Uhlaka lwesisindo samakhanda amaningi, uhlelo olusebenzisa amapharamitha ayisisekelo, ukubala kanye nesibonelo sokusetshenziswa

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Isikali samakhanda amaningi (i-Loss-in-weightfeeder) uhlobo lwemishini yokuphakelayo yokuhlaziya okulinganiselwe. Kusukela enjongweni eyinhloko, isikali samakhanda amaningi sisetshenziselwa yonke inqubo yokulinganisa okuqhubekayo okuguquguqukayo, engenza izinto zokusetshenziswa okumele zihlale zondliwe. Ukusebenza kokulinganisa kanye nokuhlaziya okulinganiselwe, futhi kukhona ukugeleza okuphelele okusheshayo kwezinto zokusetshenziswa kanye nolwazi oluphelele lokubonisa ukugeleza. Empeleni, uhlelo lokulinganisa idatha olugxilile, olusebenzisa ubuchwepheshe bokulinganisa besikali se-static data hopper, futhi lusebenzisa inzwa yokulinganisa ukukala i-hopper. Kodwa-ke, kuphaneli yokulawula yesikali samakhanda amaningi, kuyadingeka ukubala isisindo esilahlekile ngeyunithi ngayinye yesikali se-hopper ukuze kutholakale ukugeleza okuphelele kwezinto zokusetshenziswa ngokushesha.

Isithombe 1 siwumbono wohlelo lwesimiso sesisindo samakhanda amaningi. Incazelo emfushane yesisindo samakhanda amaningi, uhlelo lokuklama, ukulinganisa kanye nokusetshenziswa kwamapharamitha ayinhloko okusebenza kanye nesimo saso sokusetshenziswa. Isithombe 1. Uhlelo oluyisisekelo lwesisindo samakhanda amaningi. Isithombe 1 siwumdwebo wesakhiwo sesisindo samakhanda amaningi. Ukukhipha, lapho kufinyelelwa ezingeni eliphezulu lezinto ezibonakalayo, i-valve yokukhipha ivaliwe, futhi i-weighing hopper isekelwa yi-weighing yamakhanda amaningi. Ukuze kwenziwe isisindo sibe sinembile, izinhlangothi eziphezulu nezingezansi ze-weighing hopper zonke zixhunywe ngokwesiteshi esithambile noma umnyango nokuphuma, ukuze isisindo esiphelele semishini yangaphambili nangemuva, kwesobunxele nakwesokudla kanye nemishini kanye nezinto zokusetshenziswa zingasetshenziswa kwi-weighing hopper.

Uhlangothi lwesokudla lweSithombe 1 luwumbono wohlelo lwenqubo yonke yesiphakeli esiqhubekayo. Yonke inqubo yesiphakeli esiqhubekayo inohlelo lomjikelezo (imijikelezo emithathu ikhonjisiwe esithombeni). Uhlelo ngalunye lomjikelezo luqukethe izikhathi ezimbili zomjikelezo: lapho i-weighing hopper ingenalutho, i-discharge valve iyavulwa ukuze ikhiphe izinto, futhi isisindo esiphelele sezinto zokusetshenziswa ku-weighing hopper siyaqhubeka nokukhula. Lapho izinga eliphezulu lezinto lifinyelelwa ku-t1, i-discharge valve iyavalwa. I-screw conveyor isanda kuqala ukuthulula izinto, bese isisindisi se-multihead saqala ukusebenza; ngemva kwesikhathi esithile, lapho isisindo esiphelele sezinto zokusetshenziswa ku-weighing hopper siqhubeka nokwehla futhi safinyelela ezingeni eliphansi lezinto ku-t2, i-discharge valve yavulwa futhi, futhi isikhathi kusukela ku-t1 kuya ku-t2 kwakuyisikhathi somjikelezo we-Force feeder; ngemva kwesikhathi esithile, lapho isisindo esiphelele sezinto zokusetshenziswa ku-weighing hopper siqhubeka nokukhula futhi sifinyelela ezingeni eliphezulu lezinto futhi ngesikhathi se-t3, i-discharge valve iyavalwa, futhi isikhathi kusukela ku-t2 kuya ku-t3 yisikhathi somjikelezo wokukhipha kabusha, njalo njalo. Ngesikhathi somjikelezo we-force feeder, isilinganiso sejubane se-screw conveyor siqashwa ngokwezinga lokugeleza okusheshayo ukuze kufezwe i-feeder ezinzile; ngesikhathi somjikelezo wokukhulula kabusha, isilinganiso sejubane se-screw conveyor sizogcina isilinganiso sejubane ngaphambi nje kokuqala kwesikhathi somjikelezo. Shintsha i-feeder ibe yindlela yokuqapha ukugeleza kwevolumu engaguquki.

Ngenxa yokuthi isikali samakhanda amaningi sihlanganisa isisindo esiguquguqukayo kanye nedatha engaguquki, futhi sihlanganisa isiphakeli esiphazamisekile kanye nokondla okuqhubekayo, isakhiwo kulula ukusivala, futhi sifanelekela ukukala izinto zokusetshenziswa ezicolekile kakhulu ezifana nokhonkolo, impuphu ye-quicklime, amalahle acoliwe, ukudla, imithi, njll. Isisindo kanye nokulawula izinongo, kungafinyelela ukunemba okuphezulu kwesisindo kanye nokuhleleka. 2. Isidingo sohlelo lokuklama lwemingcele eyinhloko yokusebenza kwesikali samakhanda amaningi Lapho kuklanywa uhlelo lwesikali samakhanda amaningi, imingcele eyinhloko yokusebenza njengemvamisa yokukhipha, umthamo wokukhipha kabusha, umthamo we-hopper yokukala, kanye nesilinganiso sokukhipha kabusha kumele kucatshangelwe, ngaphandle kwalokho isikali samakhanda amaningi ngeke sisebenze kahle emsebenzini. Ikhasimende lithenge isikali samakhanda amaningi kumenzi ukuze kulungiswe imishini endaweni ukuze kuhlaziywe izici. Kuthengwe izinzwa zokukala ezingama-3 100kg kuphela. Ngemva kokusetshenziswa, kwatholakala ukuthi iphuzu lika-zero lalingazinzi, futhi ukugeleza okuphelele ngezinye izikhathi kwakungabonisi ulwazi kanye nezinye iziphambeko ezivamile.

Ngemva kokuba umenzi ethumele othile endaweni yesehlakalo, baqaphela ukuthi izinto zokusetshenziswa zomthengi yi-boric acid, ubuningi obuhlobene buyi-1510kg/m3, ukugeleza okuphelele kungama-36kg/h kuphela, kanti ukugeleza okuvamile kungama-21~24kg/h. Ukugeleza okuphelele kuncane kakhulu, i-hopper isebenzisa amaphuzu amathathu okusekela inzwa enesisindo esingu-100kg, futhi umthamo we-hopper yokuhlaziya mkhulu impela. Umuntu angalandela imithetho yesipiliyoni somsebenzi enconywe kakhulu ngezansi "Uma inani lomlotha likhulu, imvamisa yokukhipha kabusha ikhethwa njengezikhathi eziyi-15 kuya kwezingama-20/h" Ukuze kuqhutshekwe, isisindo esiphelele sokukhipha kabusha ngakunye singama-36/15~36/20, okungukuthi, 1.9kg~2.4kg. Isisindo esiphelele sezinto zokusetshenziswa ezithwalwa yinzwa ngayinye enesisindo singaphansi kwe-1 kg, futhi ububanzi bokulinganisa obufanele bungaba ngu-0.5~1%.

Ngokuvamile, ububanzi bokulinganisa obufanele benzwa yokukala kufanele okungenani bube ngu-10~30% noma ngaphezulu, ukuze kuqinisekiswe ukuthi isisindo sinembile kakhudlwana. Ngokwesisindo sezinto zokusetshenziswa ezingu-2.4kg kanye nesisindo esiphelele se-hopper kanye nemishini yokudla (njenge-screw conveyor), isisindo esiphelele singaba ngu-10kg. Uma kusetshenziswa amaseli amathathu omthwalo, ububanzi bokulinganisa beseli ngalinye lomthwalo bungakhethwa kusuka ku-5kg~ 10kg. Okusho ukuthi, ububanzi bokulinganisa benzwa engu-100kg eya-oda ekuqaleni buba bukhulu ngokuphindwe ka-10-20, okuholela ekuthembekeni okungekuhle kwe-multihead weigher kanye nokunemba okuphansi kwesisindo.

Leli cala libonisa ukuthi uhlelo lokuklama lwesikali samakhanda amaningi kumele luhambisane nendinganiso yohlelo lokuklama, futhi amapharamitha ayinhloko emishini yomshini kanye nokusebenza kwesikali samakhanda amaningi kumele anqunywe ngemva kokubalwa. 3. Ukubalwa kohlelo lokuklama lwamapharamitha ayinhloko okusebenza kwesikali samakhanda amaningi 3.1 Ukubalwa kwemvamisa yokukhipha Isithombe 1 sichaza ukusebenza kwesikali samakhanda amaningi. Uhlelo ngalunye lomjikelezo luhlanganisa yonke inqubo yokukhipha, ngakho-ke iyini imvamisa yokukhipha efanele? Kusisikali samakhanda amaningi, lapho isilinganiso sokuhlala komjikelezo sikhulu sesilayidi samandla ohlelweni ngalunye lomjikelezo (ukuhlala kwesikhathi = umjikelezo wesilayidi samandla / umjikelezo wokukhipha kabusha), kungcono, ngokuvamile kufanele kudlule u-10:1. Lokhu kungenxa yokuthi ukunemba kwesikhathi somjikelezo wesilayidi samandla kudlula kakhulu isikhathi somjikelezo wokukhulula kabusha. Lapho ukuhlala komjikelezo kwesilayidi samandla kukhulu, kulapho ukunemba okuphelele kwesikali samakhanda amaningi kuphakeme khona.

Imvamisa yesistimu yokujikeleza kwegazi ngeyunithi yesikhathi se-multihead weigher ngokuvamile ivezwa njengemvamisa yesistimu yokujikeleza kwegazi ngehora lapho inani lomlotha likhulu, okungukuthi, izikhathi/ihora. Ngenxa yokuthi umbandela usekelwe enanini elikhulu lokudla umlotha ngehora, ukudla umlotha ngeyunithi yesikhathi (isibonelo, ngomzuzwana) kuyinto engaguquki. Uma imvamisa yesistimu yokujikeleza kwegazi incane, inani lezinto ezikhishwayo liba likhulu isikhathi ngasinye, umthamo kanye nesisindo se-weight hopper likhulu, futhi ukunemba kokulahlekelwa isisindo kanye nokubala kusetshenziswa inzwa yokulinganisa enebanga elincanyana lokulinganisa kuyancipha; imvamisa yesistimu yokujikeleza kwegazi iyanda, inani lokukhishwa ngakunye liyancipha, umthamo kanye nesisindo se-weight hopper sincane, futhi ukunemba kokulahlekelwa isisindo kanye nokubala kuphakeme kusetshenziswa inzwa yokulinganisa enebanga elincane lokulinganisa.

Kodwa-ke, imvamisa yesistimu yokujikeleza kwegazi iphakeme kakhulu, imishini yomshini wokondla iqala futhi ime njalo, futhi ibhodi lokulawula le-multihead weigher livame ukushintsha phakathi kwesikhathi somjikelezo we-force feeder nesikhathi somjikelezo we-re-feeder, okuyinto engeyinhle kakhulu. Imvamisa yokuphinda ukhiphe enconyiwe kakhulu iboniswe kuThebula 1, kodwa ebaluleke kakhulu futhi enconyiwe kakhulu yimvamisa emithathu yokukhipha phakathi. Njengomthetho wesipiliyoni somsebenzi, iningi lesofthiwe yesistimu ye-loss-in-weight feeder lifaneleka kakhulu ezintweni eziwumpuphu kanye nezinto ezi-granular ezinokuguquguquka okuncane. izikhathi/ihora.

Uma inani lokuphakelwa komlotha liphansi kunenani elikhulu lokuphakelwa komlotha, imvamisa yokuphakelwa kabusha iyancishiswa, ukuze izinga lokuhlala komjikelezo we-force feeder libe likhulu, okuzuzisa kakhulu ukuthuthukisa ukunemba. Njengomthetho wesipiliyoni somsebenzi, ezinye izinhlelo zokusebenza ezinezinga eliphansi kakhulu lokugeleza kwe-feeder, yize umthamo we-hopper uncane kakhulu, zisengagcina izinto zokusetshenziswa ihora elilodwa noma ngaphezulu, futhi isikhathi sokuphakelwa kabusha sidlula ihora eli-1. Isibonelo esilandelayo: Ukugeleza okuphelele kwe-feeder enkulu kungu-2kg/h. Isilinganiso senqwaba yezinto zokusetshenziswa singu-803kg/m3. Ukugeleza okuphelele kwe-feeder enkulu kungu-2/803=0.0025m3/h. Uma umthamo we-hopper ungu-0.01m3 (cishe ulingane no-25b250m×25b250m×Usayizi we-cube hopper ofana no-25b250m), ukusetshenziswa okwanele kwezinto zokusetshenziswa okuluhlaza amahora ama-2~3, futhi inani ngalinye lokuphakelwa lingaphansi kuka-10kg, ngakho-ke asikho isidingo sokudla okuzenzakalelayo, ukudla kwenkonzo ngesandla kungabhekwa njengemithetho yokukhiqiza nokukhiqiza, kodwa ukugeleza kwayo okuphelele kuphansi kancane.

3.2 Ifomula yokubala ivolumu yokukhipha kabusha ikhethe imvamisa yokukhipha kabusha, bese kubalwa ivolumu yokukhipha kabusha kanye nevolumu iyonke yesiphakeli. Ngokusho kokuhlaziywa kwesici se-multihead weigher: izinga lokugeleza eliphelele lesiphakeli esikhulu lingu-275kg/h, ubuningi bezinto zokusetshenziswa bungu-485kg/m3, kanti izinga lokugeleza eliphelele lesiphakeli esikhulu lingu-270/480=0.561m3/h. Imvamisa yezinto ikhethwa njengezikhathi ezingu-15/h. Indlela yokubala ivolumu yokukhipha kabusha yile: ivolumu yokukhipha kabusha = inani elikhulu lomlotha (kg/h)÷Ubuningi (kg/m3)÷Imvamisa yokukhipha kabusha (imvamisa yokukhipha kabusha/h) Kulesi sibonelo, ivolumu yokukhipha kabusha = 270÷480÷15=0.0375m33.3 Ukubalwa komthamo we-hopper yokukala Umthamo we-hopper yokukala ohlelweni lokuklama ngokungangabazeki uzodlula ivolumu yokukhipha kabusha ebaliwe. Lokhu kungenxa yokuthi kubalulekile ukucabangela ukuthi i-hopper yokukala ayinakugwenywa lapho kuqaliswa ukukhipha kabusha. Kukhona futhi "izinto zokusetshenziswa ezisele" futhi ingxenye ephezulu ye-hopper inesitoreji esingenakwenzeka ukuba "sibe isikhala esikhululekile" esigcwele, uma ngasinye sibiza u-20%, khona-ke ivolumu yokukhipha kabusha ihlukaniswe ngo-0.6, futhi umthamo we-hopper odingekayo ungatholakala, futhi umthamo wokugcina we-silo wokukala kufanele ube mhlophe ngokwekhono le-silo eliqediwe. Indlela yokubala yokukhipha kabusha ivolumu: isisindo umthamo we-hopper = ukuphinda ukhiphe ivolumu÷Lapho u-k: k kuyinkomba yamandla ebalwe ye-hopper, engaba ngu-0.4~0.7, kanti u-0.6 unconywa kakhulu.

Kulesi sibonelo, Umthamo we-Weigh Hopper = 0.0375÷0.6=0.0625m3 Uma umthamo wesilo sokubumba unemininingwane efana no-0.6m3, 0.2m3, 1.b2503, njll., kufanele ukhanye kuze kufike ku-0.08m3, futhi umthamo we-weigh hopper kufanele ube ngu-0.08m3. 3.4 Izinga lokukhipha libalwa futhi ngenxa ye-multihead weiger Esikhathini somjikelezo wokukhipha kabusha, kukhethwa i-feeder yendlela eqondile ephansi, ngakho-ke ijubane lokukhipha kabusha i-feeder yokudlidliza lichazwe ukuthi lishesha kakhulu (ngokuvamile, kufanele lisebenze ngaphakathi kwamasekhondi angu-5 ~ 20). Indlela yokubala izinga lokukhipha kabusha: izinga lokukhipha kabusha = [ivolumu yokukhipha kabusha (m3)÷Isikhathi sokukhipha futhi (s)×60(s/min)]+[Ukugeleza okuphelele kwe-feeder enkulu yevolumu (m3/h)÷60 (min/h)] Kufomula 2, izinga lokukhipha futhi liqukethe izinto ezimbili.
