Uhlelo lokuklama kanye nokubalwa kwamapharamitha ayinhloko esikali samakhanda amaningi ekusebenzeni okusebenzayo

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Isisindo se-Multihead (i-Loss-in-weightfeeder) ukuhlaziywa kwenani lemishini enikeza isisindo se-net, esetshenziswa kakhulu, isisindo se-multihead sisetshenziselwa isisindo se-net esiqhubekayo esiguquguqukayo kuyo yonke inqubo, singenza isisindo se-net kanye nokuhlaziywa kwenani lezinto zokusetshenziswa okumele zinikezwe njalo, futhi sibonise ulwazi mayelana nezinto zokusetshenziswa. Ukugeleza okuphelele okusheshayo kanye nokugeleza okuphelele. Isimiso esiyisisekelo umshini wesisindo se-net data esimile kanye nemishini, ubuchwepheshe besisindo se-net sesilinganiso se-static data warehouse buyakhethwa, futhi kusetshenziswa i-load cell weight weight warehouse. Kodwa-ke, kuphaneli yokulawula ye-multihead weiger, ukuze kutholakale kangcono isisindo se-net esilahlekile ngesikhathi seyunithi yesikali se-warehouse yezinto zokusetshenziswa, kuyadingeka ukukala ukugeleza okuphelele kwe-papo kwe-total kwezinto zokusetshenziswa.

Uhlangothi lwesobunxele loMfanekiso 1 luwumdwebo wohlaka lwesikali esingekho sesisindo esiphelele. Lapho izinto zokusetshenziswa eziku-warehouse yesisindo esiphelele zingenazo izinto zokusetshenziswa ezidingekayo, i-valve yezinto zokusetshenziswa ingavulwa. Lapho indawo ephezulu yezinto zokusetshenziswa ifinyelelwe, i-valve yezinto zokusetshenziswa ivaliwe, futhi i-warehouse yesisindo esiphelele isekelwa isikali esingekho sesisindo esiphelele. Iphuzu. Ukuze kwenziwe isisindo sibe sinembile kakhudlwana, izinhlangothi eziphezulu nezingezansi ze-warehouse yesisindo zixhunywe ngokwezindlela ezithambile neminyango nezindawo zokuphuma, kanti imishini nemishini yangaphambili nangemuva, kwesobunxele nakwesokudla kanye nesisindo esiphelele sezinto zokusetshenziswa ezikuyo azingezi ku-warehouse yesisindo. Uhlangothi lwesokudla loMfanekiso 1 luwumbono wohlelo lwenqubo yonke yokunikezwa okuqhubekayo. Kukhona uhlelo lomjikelezo lwenqubo yonke yokunikezwa okuqhubekayo (ulwazi olukumfanekiso lubonisa izinhlelo zomjikelezo ezi-3).

Uhlelo ngalunye lomjikelezo luqukethe izikhathi ezimbili zomjikelezo: lapho isitoreji sesisindo se-net sizonciphisa isitoreji, isisindo se-net sezinto zokusetshenziswa eziku-net weight warehouse siyanda, futhi lapho isikhundla esiphezulu sezinto zokusetshenziswa sifinyelelwa ku-t1, i-valve yezinto zokusetshenziswa ivaliwe, futhi i-screw conveyor iqala nje ukukhipha izinto zokusetshenziswa, futhi isisindo se-net siyalahleka ngalesi sikhathi. Ngemva kokuba isikali siqale ukusebenza isikhathi esithile, isisindo se-net sezinto zokusetshenziswa eziku-net weight warehouse sizoncipha. Lapho isikhundla esincane sezinto zokusetshenziswa sifinyelelwa ku-t2, i-valve yezinto zokusetshenziswa izovulwa futhi. Isikhathi kusukela ku-t1 kuya ku-t2 sinikeza isikhathi somjikelezo wohlobo lwamandla. Ngemva kwesikhathi esithile, isisindo se-net sezinto zokusetshenziswa eziku-net weight warehouse sizokhula. Lapho isikhathi se-t3 sifinyelela isikhundla esiphezulu sezinto zokusetshenziswa futhi, i-valve yezinto zokusetshenziswa ivaliwe, futhi isikhathi kusukela ku-t2 kuya ku-t3 siphindaphindwa ngesikhathi somjikelezo wokunikezwa kwamandla, futhi isilinganiso sejubane se-screw conveyor siqashwa ngokuya ngokugeleza okusheshayo, ukuze kufezwe umjikelezo wokunikezwa ozinzile. Phakathi nesikhathi, isilinganiso sejubane se-screw conveyor sigcina isilinganiso sejubane ngaphambi nje kokuqala kwesikhathi somjikelezo futhi asishintshi, futhi sinikezwa yindlela yokuqapha ukugeleza kwevolumu engaguquki. Ngenxa yokuthi isisindo samakhanda amaningi sihlanganisa eduze isisindo esiguquguqukayo kanye nesisindo sedatha engaguquki, futhi sihlanganisa eduze ukondla okuphazamisekile kanye nokondla okuqhubekayo, isakhiwo sikulungele ukuvalwa, futhi sifanele ukhonkolo, impuphu ye-quicklime, amalahle acoliwe, ukudla, imithi kanye nezinye izinto ezincane zokusetshenziswa. Ukusebenza kokulinganisa nokondla kungafinyelela ukunemba okuphezulu kwesisindo kanye nokuhleleka. Isisindo samakhanda amabili sisebenza ngesidingo sohlelo lokuklama oluyinhloko.

Uma uklama isikali esinesisindo esingenayo, qiniseka ukuthi ucabangela imingcele yokusebenza eyinhloko efana nemvamisa yokondla, ivolumu yokondla kabusha, umthamo wokugcina impahla, kanye nesilinganiso sokondla kabusha. Ngaphandle kwalokho, isikali esingenayo isisindo esingenayo ngeke sisebenze kahle. Isibonelo, ikhasimende lithenge umshini wokulinganisa amakhanda amaningi kumkhiqizi wokulungisa imishini endaweni. Ngesikhathi sokuthenga, kwathengwa izinzwa zesisindo ezingu-3 100kg kuphela.

Umenzi uthumele othile khona manjalo ukuthi azi ukuthi izinto zokusetshenziswa zomthengi ziyisisombululo se-boric acid, ubuningi obuhlobene bungu-1510kg/m3, ukugeleza okuphelele kungu-36kg/h, kanti ukugeleza okuvamile kungu-21~24kg/h. Ukugeleza okuphelele kuncane kakhulu, i-hopper isebenzisa amaphuzu amathathu okusekela inzwa yesisindo esingu-100kg, kanti i-hopper yokuhlaziya inomthamo omkhulu. Kuyinkinga engeyona eyesayensi ekukhetheni imodeli. Enye inkinga ukuthi i-hopper ixhunywe emshinini onomthombo wokudlidliza ngesikhathi sokufakwa. Singakhetha izikhathi ezingu-15~20/h ngokuya ngezindinganiso ezilandelayo zomsebenzi ezinconywa kakhulu lapho isidingo sikhulu, futhi isisindo esiphelele sokuphakelwa ngakunye okwengeziwe singama-36/15~36/20, okungukuthi, 1.9kg~2.4kg, Isisindo esiphelele sezinto zokusetshenziswa ezithwalwa yinzwa yesisindo ngasinye singaphansi kwe-1 kg, futhi ububanzi bokulinganisa obufanele bungaba ngu-0.5~1%.

Ngokuvamile, ububanzi bokulinganisa obufanele benzwa yesisindo kufanele okungenani bube ngu-10~30% ukuqinisekisa isisindo esinembile. Ngokwesisindo esiphelele sezinto zokusetshenziswa ezingama-2.4kg kanye nesisindo esiphelele sendawo yokugcina impahla eluhlaza kanye nemishini nezinto zokusetshenziswa (isikulufo esithwalayo, njll.), isisindo esiphelele singaba ngu-10kg. Uma kusetshenziswa izinzwa ezintathu zesisindo, ububanzi bokulinganisa benzwa ngayinye yesisindo bungakhethwa kusukela ku-5kg kuya ku-10kg. Ngamanye amazwi, inani lenzwa ethengiwe engama-100kg landa ngokuphindwe kayi-10~20, ukuthembeka kwe-multihead weigher kubi, futhi ukunemba kwesisindo kuphansi.

Leli cala libonisa ukuthi uhlelo lokuklama lwesikali samakhanda amaningi kumele luhambisane nezinga lohlelo lokuklama, futhi amapharamitha ayinhloko emishini yomshini kanye nokusebenza kwesikali samakhanda amaningi awakwazi ukunqunywa ngaphandle kokulinganiswa. 3 ukusebenza kwesikali samakhanda amaningi amapharamitha ayinhloko ekubalweni kwesikimu sokuklama. 3.1 Ukubalwa kwemvamisa yokudla.

Kumshini wokulinganisa amakhanda amaningi, uma isilinganiso somjikelezo wokunikezwa kwamandla sikhulu (isilinganiso sesikhathi = umjikelezo wokunikezwa kwamandla/umjikelezo wokuphinda unikeze) ohlelweni ngalunye lokujikeleza kwegazi, kungcono, ngokuvamile kumele kudlule u-10:1. Lokhu kungenxa yokuthi uhlobo lwamandla lunikeza isikhathi sokujikeleza ngokunemba okuphezulu kakhulu kunesikhathi somjikelezo wokuphinda unikeze, futhi uma uhlobo lwamandla lunikeza isikhathi sokujikeleza isikhathi eside, kulapho ukunemba okuphelele kwesikali samakhanda amaningi kuphakeme khona. Imvamisa yesistimu yokujikeleza kwegazi ngeyunithi yesikhathi sesikali samakhanda amaningi ngokuvamile ivezwa njengemvamisa yesistimu yokujikeleza kwegazi ngehora lapho isidingo sikhulu, okungukuthi, izikhathi/ihora.

Uma kuthathwa isidingo esikhulu ngehora njengendinganiso, isikhathi sokudinga esingaguquki ngeyunithi yesikhathi (isibonelo, ngomzuzwana) yisona sidingo sangaphambili. Uma imvamisa yesistimu yokujikeleza incane, inani lokuphakelwa ngakunye liyanda, umthamo kanye nesisindo sendawo yokugcina isisindo esiphelele likhulu, ukunemba kokulinganisa isimo esingenasisindo ngokusebenzisa amazinga amaningi amaseli omthwalo, imvamisa yesistimu yokujikeleza iyanda, inani lokuphakelwa liyanda isikhathi ngasinye. Uma iphansi, umthamo kanye nesisindo sendawo yokugcina isisindo esiphelele sincane, kanye nokunemba kokusebenzisa inani elincane lamaseli omthwalo ukukala isimo esingenasisindo. Kodwa-ke, imvamisa yesistimu yomjikelezo iphakeme kakhulu, imishini yomshini wokondla ivame ukuqedwa, futhi iphaneli yokulawula ye-multihead weigher ivame ukushintsha phakathi kwesikhathi somjikelezo wokuphakelwa kwamandla kanye nesikhathi somjikelezo wokondla kabusha, futhi akukuhle kakhulu.

Njengokujwayelekile kwesipiliyoni somsebenzi, iningi lesimo esingenasisindo lihlinzeka ngesofthiwe yesistimu, ikakhulukazi yezinhlayiya ezimpuphu nezingenamanzi kahle, imvamisa yokuphinda kunikezwe ikhethwa njengezikhathi ezingu-15 ~ 20/ihora lapho isidingo sikhulu. Uma isidingo siphansi kunesidingo esikhulu, imvamisa yokuphinda kunikezwe iyancipha, futhi umjikelezo wokuphakelwa kohlobo lwamandla ubala ingxenye enkulu, okusiza ekuthuthukiseni ukunemba. Ngaphandle kokujwayelekile kwesipiliyoni somsebenzi, ezinye izinhlelo zokusebenza ezinikeza ukugeleza okuphelele okuphansi kakhulu, yize umthamo wendawo yokugcina impahla mncane kakhulu, zisengagcina izinto zokusetshenziswa ezinikeziwe isikhathi esingaphezu kwehora eli-1, kanye nesikhathi sokunikeza isikhathi esingaphezu kwehora eli-1.

Amacala alandelayo: Okukhulu kunikeza ukugeleza okuphelele okungu-2kg/h. Isilinganiso sokufakwa kwezinto zokusetshenziswa singama-803kg/m3. Ukugeleza okuphelele kokudla okukhulu kungu-2/803=0.0025m3/h.

Uma umthamo wendawo yokugcina impahla ungu-0.01m3 (cishe ulingana no-250Mm×250Mm×Usayizi wendawo yokugcina impahla eyi-cubic meter njengo-250Mm) wanele ukusetshenziswa kwezinto zokusetshenziswa ezingavuthiwe amahora ama-2 ~ amahora ama-3, futhi ukusetshenziswa ngakunye kwezinto zokusetshenziswa akudluli u-10kg, ngakho-ke izinto zokusetshenziswa ezizenzakalelayo azidingeki, futhi izinto zokusetshenziswa zabasebenzi zingacatshangelwa. Imithetho yokukhiqiza, kodwa ukulingana kokugeleza okuphelele kuphansi kancane. 3.2 Bala futhi ivolumu yokudla. Ngemva kokukhetha imvamisa yokugcwalisa kabusha, kungenzeka ukukala ivolumu yokugcwalisa kabusha kanye nevolumu yokuphakelwa iyonke.

Thatha i-multihead weiger njengesibonelo: enkulu inikeza ukugeleza okuphelele okungu-270KG/ihora. Ubuningi bezinto zokusetshenziswa bungu-485kg/m3. Ukugeleza okuphelele kokudla okunomthamo omkhulu kungu-270/480=0.561m3/ihora.

Ngesilinganiso esikhulu sokulethwa, imvamisa yokulethwa kabusha ikhethwe ukuthi ibe izikhathi ezingu-15/h. Indlela yokubala yokulayisha kabusha ivolumu: ivolumu yokulayisha kabusha = inani elikhulu lokwengeza (kg/h)÷Ubuningi (kg/m3)÷Imvamisa yokungena kabusha (imvamisa yokungena kabusha/h) Kulesi simo, ivolumu yokufaka kabusha = 270÷480÷15=0.0375m3. 3.3 Isisindo esiphelele sokubalwa kwamandla endlu yokugcina impahla.

Umthamo wendawo yokugcina izinto enesisindo esiphelele wohlelo lokuklama kumele udlule umthamo wendawo yokugcina izinto enesisindo esiphelele obaliwe. Lokhu kungenxa yokuthi indawo yokugcina izinto enesisindo esiphelele nakanjani izoba nezinto zokusetshenziswa ezisele kanye nendawo ekhululekile phezulu kwendawo yokugcina izinto lapho indawo yokugcina izinto enesisindo esiphelele iqala indawo yokugcina izinto enesisindo esiphelele. Uma ngayinye ibiza u-20%, futhi umthamo wendawo yokugcina izinto enesisindo esiphelele uhlukaniswe ngo-0.6, umthamo wendawo yokugcina izinto odingekayo ungatholakala.

Umthamo wokugcina wesitoreji sesisindo esikhethiwe kumele ube mhlophe ngokwevolumu yesitoreji esimisiwe. Indlela yokubala yokulayisha kabusha ivolumu: umthamo wesitoreji sesisindo esiphelele = umthamo wesisindo esiphelele÷k. Kule fomula: k yinkomba elinganiselwe yokusalela kwesitoreji sezinto zokusetshenziswa, okungaba ngu-0.4~0.7, kanti u-0.6 uyaphakanyiswa.

Kulesi sibonelo, isisindo esiphelele umthamo wendawo yokugcina impahla = 0.0375÷0.6=0.0625m3. Uma umthamo wendawo yokugcina impahla enobunjwa ingu-0.6m3, 0.8m3, 1.0M3 kanye nezinye izici namamodeli, ukukhanya kufanele kube ngu-0.08m3 phezulu, kanti umthamo wendawo yokugcina impahla enesisindo kufanele ube ngu-0.08m3. 3.4 Linganisa izinga lokufakwa kabusha.

Isisindo samakhanda amaningi sinikezwa ngendlela yomthamo oqondile ophansi ngesikhathi somjikelezo wokulayisha kabusha, ngakho-ke izinga lokulayisha kabusha lomshini wokulayisha kabusha lichazwe ukuthi lishesha (ngokuvamile, kufanele lilawulwe ngaphakathi kwamasekhondi angu-5 ~ 20). Indlela yokubala izinga lokulayisha kabusha: izinga lokuphinda lisetshenziswe = [ivolumu yokuphinda lisetshenziswe (m3)÷Isikhathi sokutshala kabusha (s)×60(s/min)]+[ukugeleza kwesamba esikhulu sokutshalwa kwezimali (m3/h)÷60(min/h)] Ku-Equation 2, izinga lokuphinda lisetshenziswe liqukethe izinto ezintsha ezimbili, into entsha yokuqala izinga lokwengeza elisekelwe kuvolumu yokwengeza kabusha, kanti into entsha yesibili ivame ukunganakwa ngabantu abaningi, okubonisa ukuthi izinga elifanayo lokwengeza isikhathi, izinto zokusetshenziswa okumele zigcwalise le ngxenye uma zengezwa futhi. Ngokusho kwenani, izinga lokuphinda lisetshenziswe kabusha liphindwe izikhathi ezingu-30 kunezinga lokwengeza elikhulu. Ngamanye amazwi, ngokwaleli nani, uma kulinganiswa izinga lokudla kabusha kwezinye izikali ezingenasisindo, kungalinganiselwa izikhathi ezingu-25-40 kunezinga lokwengeza elikhulu.
