Isikimu sokuklama nokubalwa kwemingcele eyinhloko ye-multihead weigher ekusebenzeni okungokoqobo

Umbhali: Smartweigh–I-Multihead Weighter

I-Multihead weigher (I-Loss-in-weightfeeder) iwukuhlaziywa kwenani lensimbi yokuhlinzeka ngesisindo, esetshenziswa kakhulu, isisindo se-multihead sisetshenziselwa isisindo esiqhubekayo esiguqukayo kuyo yonke inqubo, singakwazi ukwenza isisindo esiphelele kanye nokuhlaziywa kwenani lezinto zokusetshenziswa okufanele ihlinzekwa ngokuqhubekayo, futhi ibonise ulwazi mayelana nempahla eluhlaza. Ukugeleza okuphelele okusheshayo kanye nokugeleza okuphelele. Isimiso esiyisisekelo umshini wesisindo wenetha wedatha emile kanye nemishini, ubuchwepheshe besisindo senetha lesikali se-static data warehouse sikhethiwe, futhi indawo yokugcina impahla yesisindo se-load cell isetshenziswa. Kodwa-ke, kuphaneli yokulawula ye-multihead weigher, ukuze uthole kangcono isisindo esilahlekile ngesikhathi seyunithi yesilinganiso sempahla eluhlaza, kuyadingeka ukukala ukugeleza okuphelele okukhona ngaleso sikhathi kwezinto zokusetshenziswa.

Uhlangothi lwesobunxele loMfanekiso 1 luwumdwebo wefreyimu yesikali esishodayo esinesisindo. Lapho izinto zokusetshenziswa endaweni yokugcina isisindo senetha zingenazo izinto zokusetshenziswa ezidingekayo, i-valve yempahla eluhlaza ingavulwa. Lapho isikhundla esiphezulu sempahla eluhlaza sifinyelelwa, i-valve yempahla eluhlaza ivaliwe, futhi indawo yokugcina isisindo inetha isekelwa isikali esilahlekile esinesisindo. Khomba. Ukuze wenze ukukala kunembe kakhudlwana, izinhlangothi ezingenhla nezingezansi zendlu yokugcina isisindo zixhunywe ngokuvumelana neziphaseji ezithambile nezintuba zokungena nokuphuma, kanye nangaphambili nangemuva, kwesokunxele nakwesokudla imishini kanye nemishini kanye nesisindo esinetha sezinto ezingavuthiwe. akwengezi enqolobaneni yokukala. Uhlangothi lwesokudla loMfanekiso 1 wumbono wohlelo wayo yonke inqubo yokuhlinzeka ngokuqhubekayo. Kukhona uhlelo lomjikelezo wenqubo yonke yokunikezwa okuqhubekayo (ulwazi olusesithombeni lubonisa izinhlelo zomjikelezo we-3).

Uhlelo ngalunye lomjikelezo luqukethe izikhathi zomjikelezo we-2: lapho i-net weight arehouse iwukunciphisa indawo yokugcina impahla, isisindo esinetha sezinto zokusetshenziswa endaweni yokugcina isisindo senetha siyakhuphuka, futhi lapho isikhundla esiphezulu sempahla eluhlaza sifinyelelwa ku-t1, impahla eluhlaza. i-valve ivaliwe, futhi i-screw conveyor iqala nje ukukhipha izinto zokusetshenziswa, futhi isisindo senetha siyalahleka ngalesi sikhathi. Ngemuva kokuthi isikali siqale ukusebenza isikhathi esithile, isisindo senetha sezinto zokusetshenziswa endaweni yokugcina isisindo senetha sizokwehla. Lapho ubuncane bendawo yempahla eluhlaza bufinyelelwa ku-t2, ivalvu yempahla eluhlaza izovulwa futhi. Isikhathi esisuka ku-t1 siye ku-t2 sinikeza isikhathi somjikelezo sohlobo lwamandla. Ngemva kwesikhathi esithile, isisindo senetha sezinto zokusetshenziswa endaweni yokugcina isisindo senetha sizokhula. Uma isikhathi esingu-t3 sifinyelela endaweni ephezulu yezinto ezingavuthiwe futhi, i-valve yezinto ezingavuthiwe iyavalwa, futhi isikhathi esisuka ku-t2 siye ku-t3 siyaphindwa ngesikhathi somjikelezo wokunikezwa kwamandla, futhi isilinganiso sesivinini se-screw conveyor siyagadwa ngokuya ngokugeleza okusheshayo. , ukuze kuzuzwe umjikelezo wokuhlinzeka ozinzile. Phakathi nesikhathi, isilinganiso sesivinini se-screw conveyor sigcina isilinganiso sejubane ngaphambi nje kokuqala kwesikhathi somjikelezo futhi asishintshi, futhi sinikezwa indlela yokuqapha ukugeleza kwevolumu engashintshi. Ngenxa yokuthi isikali se-multihead sihlanganisa eduze isisindo esiguquguqukayo kanye nesisindo sedatha emile, futhi sihlanganisa eduze ukuphakela okuphazamisekile nokudla okuqhubekayo, lesi sakhiwo sivumela ukuvaleka, futhi sifaneleka ukhonkolo, impushana esheshayo, amalahle agayiwe, ukudla, imithi nezinye izinto ezincane zokusetshenziswa. Ukukala kanye nokusebenza kokuphakela kungafinyelela ukunemba okuphezulu kwesisindo kanye nomugqa. I-2multihead weigher isebenza ngesidingo sohlelo oluyinhloko lokuklama ipharamitha.

Uma uklama isikali esinesisindo esingekho, qiniseka ukuthi ucabangela imingcele yokusebenza eyinhloko efana nemvamisa yokondla, umthamo wokondla kabusha, umthamo wokuphakelwa kabusha kwempahla, kanye nezinga lokuphakela kabusha. Uma kungenjalo, isikali esilahlekile ngesisindo ngeke sisebenze kahle. Isibonelo, ikhasimende lithenge i-multihead weigher kumkhiqizi ukuze kulungiswe imishini esizeni. Ngesikhathi sokuthenga, kwathengwa kuphela izinzwa zesisindo esingu-3 100kg.

Umkhiqizi uthumele othile khona lapho ukuze azi ukuthi impahla eluhlaza yekhasimende iyisixazululo se-boric acid, ukuminyana okuhlobene ngu-1510kg/m3, ukugeleza okuphelele okungu-36kg/h, kanti ukugeleza okuphelele 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 amamodeli. Enye inkinga ukuthi i-hopper ixhunywe emshinini onomthombo wokudlidliza ngesikhathi sokufakwa. Singakhetha izikhathi ezingu-15–20/h ngokuvumelana nalawa mazinga alandelayo anconywe kakhulu okuhlangenwe nakho komsebenzi lapho isidingo sisikhulu, futhi isisindo sengqikithi yokunikezwayo ngakunye okwengeziwe ngu-36/15~36/20, okungukuthi, 1.9kg~2.4kg, Isisindo sengqikithi yezinto ezingavuthiwe ezithwalwa inzwa ngayinye yesisindo singaphansi kuka-1 kg, futhi ububanzi bokulinganisa obunengqondo bungaba ngu-0.5~1%.

Ngokuvamile, ububanzi bokulinganisa obunengqondo benzwa yesisindo kufanele okungenani bube ngu-10~30% ukuze kuqinisekiswe ukukala okunembe kakhudlwana. Ngokwesisindo esiphelele sempahla eluhlaza engu-2.4kg kanye nenetha yesisindo sendawo yokugcina impahla eluhlaza kanye nemishini yempahla eluhlaza kanye nemishini (i-screw conveyor, njll.), isisindo esiphelele singaba ngu-10kg. Uma kusetshenziswa izinzwa zesisindo ezintathu, ububanzi bokulinganisa benzwa ngayinye yesisindo ingakhethwa ukusuka ku-5kg ukuya ku-10kg. Ngamanye amazwi, inani lenzwa ye-100kg ethengiwe likhuphuka izikhathi ezingu-10 ~ 20, ukwethembeka kwesisindo se-multihead kubi, futhi ukunemba kwesisindo kuphansi.

Leli cala libonisa ukuthi uhlelo lokuklama lwe-multihead weigher kufanele futhi luhambisane nesimiso sohlelo lokuklama, futhi imingcele eyinhloko yemishini yomshini kanye nokusebenza kwe-multihead weigher ayikwazi ukunqunywa ngaphandle kokulinganisa. 3 amapharamitha amakhulu wokukala isikali se-multihead wokubala kwesikimu sokuklama. 3.1 Ukubalwa kobuningi bokudla.

Ngesikali se-multihead, isilinganiso esikhulu somjikelezo wokunikezwa kwamandla (isilinganiso sesikhathi = umjikelezo wokunikezwa kwamandla / umjikelezo wokunikezela kabusha) ohlelweni ngalunye lokujikeleza kwegazi, okungcono, ngokuvamile kufanele kudlule u-10:1. Lokhu kungenxa yokuthi uhlobo lwamandla lunikeza isikhathi somjikelezo ngokunemba okuphezulu kakhulu kunesikhathi somjikelezo wokunikezela kabusha, futhi uma uhlobo lwamandla lunikeza isikhathi somjikelezo, kuphakama ukunemba okuphelele kwesikali se-multihead. Imvamisa yesistimu yokujikeleza kwegazi ngeyunithi ngayinye yesisindo se-multihead ngokuvamile ivezwa njengemvamisa yesistimu yokujikeleza kwegazi ngehora lapho isidingo sisikhudlwana, okungukuthi, izikhathi/h.

Ukuthatha isidingo esikhulu ngehora njengesijwayelekile, isikhathi sokufunwa singaguquguquki ngesikhathi seyunithi (isibonelo, ngesekhondi ngalinye) umbandela wangaphambili. Uma kuncane ukuvama kwesistimu yokujikeleza, inani elikhulu lokuphakelwa ngakunye, amandla amakhulu kanye nesisindo esiphelele sempahla yesisindo senetha, kuncipha ukunemba kokulinganisa isimo esingenasisindo ngokusebenzisa amazinga amaningi amaseli omthwalo, kulapho-ke khona imvamisa yesistimu yokujikeleza, inani elikhulu lokudla isikhathi ngasinye. Okuphansi kwayo, kuncane umthamo nesisindo esiphelele se-net weight warehouse, futhi kukhuphuka ukunemba kokusebenzisa inani elincane lamaseli omthwalo ukukala isimo esingenasisindo. Kodwa-ke, imvamisa yesistimu yomjikelezo iphezulu kakhulu, umshini wokuphakelayo uvame ukunqanyulwa, futhi iphaneli yokulawula ye-multihead weigher ivame ukushintsha phakathi kwesikhathi somjikelezo wokuphakela amandla kanye nesikhathi somjikelezo wokubuyisela, futhi akukuhle kakhulu.

Njengokujwayelekile kokuhlangenwe nakho komsebenzi, iningi lesimo esingenasisindo sinikeza isofthiwe yesistimu, ikakhulukazi i-powdery kanye nezinhlayiya ezingasebenzi kahle, imvamisa yokubuyisela ikhethwa njengezikhathi ezingu-15 ~ 20 / ihora lapho isidingo sikhulu. Uma isidingo siphansi kunesidingo esikhulu, imvamisa yokuhlinzekwa kabusha iyancishiswa, futhi umjikelezo wokunikezwa kohlobo lwamandla ubala ingxenye enkulu, ehambisana nokuthuthukisa ukunemba. Ngaphandle kokujwayelekile kokuhlangenwe nakho komsebenzi, ezinye izinhlelo zokusebenza ezinikeza ukugeleza okuphelele okuphansi ikakhulukazi, nakuba umthamo we-warehouse mncane kakhulu, zingakwazi ukugcina izinto zokusetshenziswa ezihlinzekwe ngaphezu kwehora elingu-1, kanye nesikhathi sokuhlinzeka ngehora eli-1.

Lezi zimo ezilandelayo: Okukhudlwana kunikeza ukugeleza okuphelele kwe-2kg/h. I-raw material deposition ratio ngu-803kg/m3. Ukugeleza okuphelele kokuphakela kwevolumu enkulu ngu-2/803=0.0025m3/h.

Uma umthamo we-warehouse ungu-0.01m3 (cishe ukulingana no-250Mm×250Mm×Usayizi we-cubic meter warehouse njengo-250Mm) wanele u-2h~3h wokusetshenziswa kwempahla eluhlaza, futhi ukusetshenziswa ngakunye kwempahla eluhlaza akudluli u-10kg, ngakho-ke izinto zokusetshenziswa ezizenzakalelayo azidingeki, futhi izinto zokusetshenziswa zabasebenzi zingacatshangelwa. Imithethonqubo yokukhiqiza, kodwa isamba sokugeleza kwemigqa singaphansi kancane . 3.2 Bala umthamo wokuphakela futhi. Ngemuva kokukhetha imvamisa yokugcwalisa, kungenzeka ukukala ivolumu yokugcwalisa kanye nevolumu yokunikezela okuphelele.

Thatha isikali se-multihead njengesibonelo: esikhulu sinikeza ukugeleza okuphelele kuka-270KG/ihora. Ukuminyana kwenqwaba yezinto ezingavuthiwe ngu-485kg/m3. Isamba sokugeleza kokuphakela umthamo omkhulu ngu-270/480=0.561m3/h.

Ngesilinganiso esikhulu sokulethwa, imvamisa yokulethwa kabusha ikhethwe ukuthi ibe izikhathi eziyi-15/h. Indlela yokubala yokulayisha kabusha ivolumu: ivolumu yokulayisha kabusha = inani elikhulu lokwengeza (kg/h)÷Ukuminyana (kg/m3)÷Imvamisa yokuphinda ufake (imvamisa yokuphinda ungene/h) Kulesi simo, ivolumu yokufaka kabusha = 270÷480÷15=0.0375m3. 3.3 Isibalo sengqikithi yendawo yokugcina impahla.

Umthamo we-net we-warehouse yesisindo sohlelo lokuklama kufanele udlule umthamo we-net onesisindo esibaliwe. Lokhu kungenxa yokuthi i-net weight warehouse izoba nezinto zokusetshenziswa ezisele kanye nesikhala samahhala phezulu kwendawo yokugcina impahla lapho i-net weight warehouse iqala i-net weight warehouse. Uma i-akhawunti ngayinye ibiza u-20%, futhi umthamo we-net weight store uhlukaniswa ngo-0.6, umthamo odingekayo we-warehouse ungatholakala.

Ivolumu yokugcina ekhethiwe yesisindo senetha kufanele ibe cwebezelayo ngokuya ngevolumu yendlu yokugcina impahla engashintshi. Indlela yokubala yokulayisha kabusha ivolumu: umthamo wesitoreji sesisindo senetha = ivolumu yesisindo esisele÷k. Kufomula: k iyinkomba yemali esele elinganiselwe yendlu yokugcina impahla engavuthiwe, engaba ngu-0.4~0.7, futhi u-0.6 uyahlongozwa.

Kulesi sibonelo, umthamo we-net weight store = 0.0375÷0.6=0.0625m3. Uma ivolumu yendlu yokugcina impahla emise okuwu-0.6m3, 0.8m3, 1.0M3 nezinye izicaciso namamodeli, isicwebezelisi kufanele sibe ngu-0.08m3 phezulu, futhi umthamo wesitolo esikala kufanele ube ngu-0.08m3. 3.4 Linganisa izinga lokufakwa kabusha.

Isikali se-multihead sinikezwa indlela yomthamo ongaguquki enembayo ephansi ngesikhathi somjikelezo wokulayisha kabusha, ngakho izinga lokulayisha kabusha lomshini wokulayisha kabusha licaciswa ukuthi liyashesha (ngokuvamile, kufanele lilawulwe phakathi kwama-5s~20s). Indlela yokubala yezinga lokulayisha kabusha: isilinganiso sokwenza imali kabusha = [ivolumu yokuvuselela kabusha (m3)÷Isikhathi sokutshalwa kabusha (s)×60(s/min)]+[isamba esikhulu sokugeleza kwesamba esikhulu sokutshala imali (m3/h)÷60(min/h)] Ku-Equation 2, isilinganiso sokwengeza kabusha siqukethe izinto ezintsha ezi-2, into yokuqala entsha yizinga lokwengezwa elisekelwe kuvolumu yokwengezwa kabusha, futhi into yesibili entsha ngokuvamile ayinakwa abantu abaningi, okubonisa ukuthi okufanayo Izinga lokwengeza isikhathi, impahla eluhlaza okufanele igcwalise le ngxenye uma yengezwe futhi. Ngokwevelu, izinga lokuphakela kabusha licishe liphindwe izikhathi ezingu-30 kunesilinganiso esikhulu sokwengezwa. Ngamanye amazwi, ngokwaleli nani, lapho ulinganisela izinga lokuphakela kabusha kwezinye izikali ezintula isisindo, lingalinganiselwa izikhathi ezingu-25-40 inani elikhulu lokungeza. .
