Umbhali: Smartweigh–I-Multihead Weighter

I-multihead weigher (I-Loss-in-weightfeeder) iwuhlobo lokuhlaziya ubuningi bemishini yokuphakelayo. Kusukela enjongweni eyinhloko, i-multihead weigher isetshenziselwa yonke inqubo yesisindo esiqhubekayo esiguquguqukayo, esingakwazi ukwenza izinto zokusetshenziswa okufanele zondliwe ngokuqhubekayo. Ukusebenza kokuhlaziya isisindo nobuningi, futhi kukhona ukugeleza okuphelele okusheshayo kwezinto zokusetshenziswa kanye nolwazi oluphelele lokubonisa ukugeleza. Ngokuyisisekelo, iwuhlelo lokukala idatha olumile, olwamukela ubuchwepheshe bokukala besikali se-static hopper yedatha, futhi isebenzisa inzwa yokukala ukukala i-hopper. Kodwa-ke, kuphaneli yokulawula ye-multihead weigher, kuyadingeka ukubala isisindo esilahlekile ngesikhathi seyunithi yesilinganiso se-hopper ukuze kutholwe ukugeleza okuphelele okukhona ngaleso sikhathi kwezinto zokusetshenziswa.

Umfanekiso 1 uwumbono wohlelo lomgomo we-multihead weigher. Incazelo emfushane ye-multihead weigher, uhlelo lokuklama, ukulinganisa kanye nokusetshenziswa kwemingcele eyinhloko yokusebenza kanye necala lokufaka isicelo. Umfanekiso 1. Uhlelo lomgomo lwesisindo se-multihead. Umfanekiso 1 wumdwebo wohlelo lwesakhiwo se-multihead weigher. Ukukhishwa, lapho izinga eliphezulu lezinto ezibonakalayo lifinyelelwa, i-valve yokukhipha ivaliwe, futhi i-hopper enesisindo isekelwa i-multihead weigher. Ukuze wenze isikali sinembile, izinhlangothi ezingenhla nezingezansi ze-hopper enesisindo zonke zixhunywe ngokuvumelana nesiteshi esithambile noma indawo yokungena nokuphuma, ukuze isisindo senetha sangaphambili nangemuva, kwesokunxele nesokudla imishini kanye nemishini kanye izinto ezingavuthiwe azisetshenziswa ku-hopper yokukala.

Uhlangothi lwesokudla loMfanekiso 1 wumbono wohlelo wayo yonke inqubo yesiphakeli esiqhubekayo. Yonke inqubo ye-feeder eqhubekayo inesistimu yomjikelezo (imijikelezo emithathu iboniswa esithombeni). Isistimu yomjikelezo ngamunye iqukethe izikhathi ezimbili zomjikelezo: lapho i-hopper yokukala ingenalutho, i-valve yokukhipha ivuliwe ukuze kukhishwe impahla, futhi isisindo senetha sempahla eluhlaza ku-hopper yokukala siyaqhubeka nokukhula. Lapho izinga eliphezulu lezinto ezibonakalayo lifinyelelwa ku-t1, i-valve yokukhipha ivaliwe. I-screw conveyor isanda kuqala ukuthulula i-material, kwase-ke isikali se-multihead saqala ukusebenza; ngemva kwesikhathi esithile, lapho isisindo senetha sempahla eluhlaza ku-hopper yokukala siqhubeka nokuncipha futhi safinyelela ezingeni lempahla elincane ku-t2, ivalvu yokukhipha yavulwa futhi, futhi isikhathi esisuka ku-t1 siye ku-t2 kwakuwumsebenzi Wokujikeleza kokuphakelayo. isikhathi; ngemva kwesikhathi esithile, lapho isisindo senetha sempahla eluhlaza ku-hopper enesisindo siqhubeka nokukhula futhi sifinyelela ezingeni eliphezulu lempahla futhi ngesikhathi se-t3, i-valve yokukhipha ivaliwe, futhi isikhathi esivela ku-t2 kuya ku-t3 yisikhathi somjikelezo we ukukhipha kabusha, nokunye. Phakathi nesikhathi somjikelezo wesiphakeli samandla, isilinganiso sesivinini se-screw conveyor siyagadwa ngokuya ngesilinganiso sokugeleza esisheshayo ukuze kuzuzwe okuphakelayo okuzinzile; phakathi nesikhathi somjikelezo wokukhipha kabusha, isilinganiso sesivinini se-screw conveyor sizogcina isilinganiso sejubane ngaphambi nje kokuqala kwesikhathi somjikelezo. Shintsha i-feed ibe indlela yokuqapha ukugeleza kwevolumu engashintshi.

Ngenxa yokuthi isikali se-multihead sihlanganisa isisindo esishintshayo kanye nesisindo sedatha emile, futhi sihlanganisa okuphakelayo okuphazamisekile nokudla okuqhubekayo, isakhiwo kulula ukusivala, futhi silungele ukukala izinto ezingavuthiwe ezinjengokhonkolo, impushana esheshayo, amalahle agayiwe, ukudla. , imithi, njll. Ukulawulwa kwesisindo kanye nezinongo, kungafinyelela ukunemba okuphezulu kwesisindo kanye nokulandelana. 2. Isidingo sohlelo lokuklama lwemingcele eyinhloko yokusebenza kwe-multihead weigher Lapho uklama uhlelo lwe-multihead weigher, imingcele eyinhloko yokusebenza njengemvamisa yokukhishwa, ivolumu yokukhishwa kabusha, amandla i-hopper yokukala, kanye nezinga lokukhishwa kabusha kufanele kucatshangelwe, ngaphandle kwalokho isikali se-multihead ngeke sisebenze kahle emsebenzini. Ikhasimende lithenge i-multihead weigher kumkhiqizi ukuze kulungiswe imishini esizeni ukuze kuhlaziywe izici. Kuthengwe izinzwa ezinesisindo esingu-3 100kg kuphela. Ngemva kokusetshenziswa, kwatholakala ukuthi iphuzu elinguziro lalingazinzile, futhi ukugeleza okuphelele ngezinye izikhathi akuzange kubonise ulwazi namanye amaphutha avamile.

Ngemuva kokuthi umkhiqizi ethumele othile endaweni yesigameko, baqaphela ukuthi impahla eluhlaza yekhasimende yi-boric acid, ukuminyana okuhlobene ngu-1510kg/m3, ukugeleza okuphelele kungu-36kg/h kuphela, kanti ukugeleza okuphelele okuvamile kungu-21~24kg/ h. Ukugeleza okuphelele kuncane kakhulu, i-hopper ithatha amaphuzu amathathu okusekela izinzwa ezinesisindo esingu-100kg, futhi amandla e-hopper yokuhlaziya makhulu impela. Umuntu angalandela imithetho yesipiliyoni somsebenzi enconywa kakhulu engezansi“Uma inani lomlotha likhulu, imvamisa yokukhipha kabusha ikhethwa njengezikhathi eziyi-15 kuye kwezingama-20/h.”Ukuze udlulise, isisindo sengqikithi yokukhipha kabusha ngakunye ngu-36/15~36/20, okungukuthi, 1.9kg~2.4kg. Isisindo sengqikithi yezinto ezingavuthiwe ezithwalwa inzwa ngayinye enesisindo singaphansi kwe-1 kg, futhi ububanzi bokulinganisa obunengqondo bucishe bube ngu-0.5~1%.

Ngokuvamile, ububanzi bokulinganisa obuphusile benzwa yokukala kufanele okungenani bube ngu-10~30% noma ngaphezulu, ukuze kuqinisekiswe ukukala okunembe kakhudlwana. Ngokwesisindo sempahla eluhlaza engu-2.4kg kanye nenethi yesisindo se-hopper kanye nempahla yokudla (njenge-screw conveyor), isisindo esiphelele singaba ngu-10kg. Uma kusetshenziswa amaseli omthwalo amathathu, uhla lokulinganisa lweseli ngayinye yomthwalo lungakhethwa kusukela ku-5kg ~ 10kg. Okusho ukuthi, uhla lokulinganisa lwenzwa eyi-100kg eyayalelwe ekuqaleni luba lukhudlwana izikhathi eziyi-10-20, okuholela ekuthembekeni okubi kwesisindo se-multihead kanye nokunemba okuphansi kwesisindo.

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 kufanele inqunywe ngemva kokubala. 3. Ukubalwa kohlelo lokuklama lwemingcele eyinhloko yokusebenza kwe-multihead weigher 3.1 Ukubalwa kwemvamisa yokukhipha Umfanekiso 1 uchaza ukusebenza kwesikali se-multihead. Uhlelo ngalunye lomjikelezo luhlanganisa yonke inqubo yokukhishwa, ngakho-ke isiphi imvamisa yokukhishwa efanele? Esilinganisweni se-multihead, lapho isilinganiso sokuhlala komjikelezo we-force feeder sikhulu kusistimu yomjikelezo ngamunye (ukuhlala isikhathi = umjikelezo we-force feeder / umjikelezo wokukhipha kabusha), kungcono, ngokuvamile kufanele kudlule u-10:1. Lokhu kungenxa yokuthi ukunemba kwesikhathi somjikelezo wesiphakeli samandla sidlula kude isikhathi somjikelezo wokukhipha kabusha. Uma kukhulu ukuhlala komjikelezo wesiphakeli samandla, kuphakama ukunemba kukonke kwesisindo se-multihead.

Imvamisa yesistimu yokujikeleza kwegazi ngeyunithi ngayinye yesisindo se-multihead ngokuvamile ivezwa njengemvamisa yesistimu yokujikeleza kwegazi ngehora lapho inani lomlotha likhulu, okungukuthi, izikhathi/h. Ngenxa yokuthi umbandela wangaphambili usekelwe enanini elikhulu lokuphakela umlotha ngehora, ukuphakelwa komlotha ngesikhathi seyunithi (isibonelo, ngomzuzwana) kuyisikhathi esingaguquki. Uma kuncane ukuvama kwesistimu yokujikeleza, likhulu inani lempahla ekhishwayo isikhathi ngasinye, sikhulu umthamo nesisindo senetha se-hopper yokukala, futhi kwehlisa ukunemba kokuncipha kwesisindo nokubala kusetshenziswa inzwa yesisindo samabanga amaningi; kulapho imvamisa yesistimu yokujikeleza, Yehlisa inani lokuphuma ngakunye, iba mncane umthamo nesisindo senetha se-hopper enesisindo, futhi kuphakama ukunemba kokuncipha kwesisindo nokubala kusetshenziswa inzwa yokukala enobubanzi obuncane bokulinganisa.

Kodwa-ke, imvamisa yesistimu yokujikeleza iphezulu kakhulu, imishini yomshini wokuphakela iqala futhi ime njalo, futhi ibhodi lokulawula le-multihead weigher livame ukushintsha phakathi kwesikhathi somjikelezo we-force feeder kanye nesikhathi somjikelezo wokuphakela kabusha, okuyinto akukuhle kakhulu. Amafrikhwensi okuphinda anconywe anconywe kakhulu aboniswa kuThebula 1, kodwa okubaluleke kakhulu nokunconywa kakhulu amaza okuphuma amathathu aphakathi nendawo. Njengomthetho wesipiliyoni somsebenzi, iningi lesofthiwe yesistimu yokuphakelwa kwesisindo ifaneleka kakhulu ezintweni eziyimpuphu nezinto eziyimbudumbudu ezinoketshezi olubi. izikhathi/ihora.

Uma inani lokuphakela umlotha liphansi kunenani elikhulu lokuphakela umlotha, imvamisa yokuphakelwa kabusha iyancishiswa, ukuze izinga lokuhlala komjikelezo we-force feeder libe likhulu, okuzuzisa kakhulu ukuthuthukisa ukunemba. Njengomthetho wokuhlangenwe nakho komsebenzi, ezinye izinhlelo zokusebenza ezinezinga eliphansi kakhulu lokugeleza okuphelele kwe-feeder, nakuba umthamo we-hopper mncane kakhulu, zingakwazi ukugcina izinto zokusetshenziswa ihora elilodwa noma isikhathi eside sokuphakela, futhi isikhathi sokuphakela kabusha sidlula ihora elingu-1. . Isibonelo esilandelayo: Ukugeleza okuphelele kwesiphakeli esikhulu ngu-2kg/h. Isilinganiso senqwaba yezinto ezingavuthiwe ngu-803kg/m3. Ukugeleza okuphelele kwesiphakeli sevolumu enkulu ngu-2/803=0.0025m3/h. Uma umthamo we-hopper ungu-0.01m3 (cishe ulingane no-25b250m×25b250m×Ubukhulu be-cube hopper efana ne-25b250m), ukusetshenziswa kwempahla eluhlaza eyanele ye-2h~3h, futhi inani ngalinye lokuphakela lingaphansi kwe-10kg, ngakho-ke asikho isidingo sokuphakelwa okuzenzakalelayo, ukuphakelwa kwenkonzo okwenziwa ngesandla kungabhekwa imithethonqubo yokukhiqiza nokukhiqiza, kodwa ingqikithi yayo. ukugeleza kunomugqa ngaphansi kancane.

3.2 Ifomula yokubala ivolumu yokuphinda ikhishwe ikhethe imvamisa yokuphinda ikhishwe, bese kuba khona umthamo wokuphinda uchithe kanye nenani eliphelele levolumu yesiphakeli singabalwa. Ngokohlaziyo lwesici sesikali se-multihead: isamba sokugeleza kwesiphakeli esikhulu singu-275kg/h, ukuminyana kwenqwaba yezinto ezingavuthiwe ngu-485kg/m3, kanti inani lokugeleza kwesilinganiso sokuphakela kwevolumu enkulu ngu-270/480= 0.561m3/h. Imvamisa yezinto ezibonakalayo ikhethwa njengezikhathi eziyi-15/h. Indlela yokubala yevolumu yokukhishwa kabusha yile: ivolumu yokukhishwa kabusha = inani elikhulu lomlotha (kg/h)÷Ukuminyana (kg/m3)÷Imvamisa yokukhipha kabusha (imvamisa yokukhipha kabusha/h) Kulesi sibonelo, khipha kabusha ivolumu = 270÷480÷15=0.0375m33.3 Ukubalwa komthamo we-hopper yokukala Umthamo we-hopper yokukala ohlelweni lokuklama ngokungangabazeki uzodlula ivolumu yokukhipha kabusha okubaliwe. Lokhu kungenxa yokuthi kuyadingeka ukucabangela ukuthi i-hopper yokukala ayinakugwenywa lapho ukukhulula kabusha kuqalwa. Bakhona futhi“Izinto zokusetshenziswa ezisele”futhi ingaphezulu le-hopper linendawo yokubeka okungenzeka ukuthi ngeke igcwale“Indawo engenalutho”, uma i-akhawunti ngayinye i-20%, khona-ke ivolumu yokukhipha kabusha ihlukaniswa ngo-0.6, futhi umthamo we-hopper odingekayo ungatholakala, futhi umthamo wokugcina we-silo wesisindo kufanele ube ocwebezelayo ngokuvumelana nomthamo we-silo oqediwe. Indlela yokubala yevolumu yokukhipha kabusha: ukukala umthamo we-hopper = ivolumu yokukhipha kabusha÷Lapho u-k: k kuyinkomba yomthamo obaliwe we-hopper, engaba ngu-0.4~0.7, futhi u-0.6 utuswa kakhulu.

Kulesi sibonelo, I-Weigh Hopper Capacity = 0.0375÷0.6=0.0625m3 Uma umthamo wesisele sokubunjwa unemininingwane efana no-0.6m3, 0.2m3, 1.b2503, njll., kufanele icwebezele ifike ku-0.08m3, futhi umthamo we-hopper enesisindo kufanele ube ngu-0.08m3. 3.4 Izinga lokukhipha libalwa futhi ngenxa yesisindo se-multihead Esikhathini somjikelezo wokuphinda ukhiphe, okuphakelayo okunemba okuphansi kwekhono elingaguquki kuyakhethwa, ngakho-ke isivinini sokukhipha kabusha sesiphakeli esidlidlizayo sicaciswa ukuthi siyashesha (ngokuvamile, kufanele isetshenziswe phakathi kwama-5s ~ 20s). Indlela yokubala yezinga lokukhipha kabusha: izinga lokuphinda likhishwe = [ivolumu yokukhipha kabusha (m3)÷Isikhathi sokukhipha futhi (s)×60(s/min)]+[Isamba sokugeleza kwesiphakeli sevolumu enkulu (m3/h)÷60 (min/h)] Kufomula 2, izinga lokukhipha futhi liqukethe izinto ezimbili.
