Umbhali: Smartweigh–Multihead Weighter

I-multihead weigher (I-Loss-in-weightfeeder) luhlobo lohlalutyo lobungakanani obunobunzima besixhobo sokutyisa. Ukusuka kweyona njongo iphambili, i-multihead weigher isetyenziselwa yonke inkqubo yobunzima obuguqukayo obuqhubekayo, obunokwenza izinto eziluhlaza ekufuneka zondliwe ngokuqhubekayo. Umsebenzi wokuvavanya ubungakanani kunye nobungakanani, kwaye kukho ukuhamba okupheleleyo kwangoko kwemathiriyeli ekrwada kunye nolwazi lulonke lokubonisa ukuhamba ngokupheleleyo. Ukuthetha ngokusisiseko, yinkqubo yokuveyisha idatha engatshintshiyo, eyamkela itekhnoloji yokuweyisha yesikali se-static data hopper, kwaye isebenzisa isivayimbo sovavanyo ukulinganisa i-hopper. Nangona kunjalo, kwiphaneli yokulawula ye-multihead weigher, kuyimfuneko ukubala ubunzima obulahlekileyo ngexesha leyunithi yesikali se-hopper ukufumana ukuhamba okupheleleyo kwangoko kwezinto ezikrwada.

Umzobo 1 ngumbono wesicwangciso somgaqo we-multihead weigher. Inkcazo emfutshane ye-multihead weigher, isicwangciso soyilo, umlinganiselo kunye nokusetyenziswa kweeparamitha eziphambili zokusebenza kunye nesicelo sayo. Umzobo 1. Isicwangciso somgaqo we-multihead weigher. Umzobo 1 ngumzobo oqingqiweyo wesakhiwo se-multihead weigher. Ukukhutshwa, xa ubuninzi bezinto eziphathekayo bufikeleleke, i-valve yokukhupha ivaliwe, kwaye i-hopper yokulinganisa ixhaswa yi-multihead weigher. Ukuze wenze umlinganiso ochanekileyo, amacala aphezulu nasezantsi e-hopper yokulinganisa onke adityaniswe ngokuhambelana nomjelo othambileyo okanye indawo yokungena kunye nokuphuma, ukwenzela ukuba ubunzima bomnatha obungaphambili nasemva, obusekhohlo nasekunene kunye nezixhobo kunye nezixhobo. izinto ezikrwada azisetyenziswa kwihopha yokulinganisa.

Icala lasekunene loMfanekiso 1 yimbono yesicwangciso sayo yonke inkqubo ye-feeder eqhubekayo. Yonke inkqubo ye-feeder eqhubekayo inenkqubo yomjikelezo (imijikelo emithathu ibonakaliswe kumzobo). Inkqubo nganye yomjikelo iqukethe amaxesha amabini okujikeleza: xa i-hopper yokulinganisa ingenanto, i-valve yokukhupha ivuliwe ukuze ikhuphe izinto eziphathekayo, kwaye ubunzima bobuncwane bezinto eziluhlaza kwi-hopper yokulinganisa buqhubeka bukhula. Xa umgangatho ophezulu wezinto eziphathekayo ufikelele kwi-t1, i-valve yokukhupha ivaliwe. I-screw conveyor yaqala nje ukugalela izinto, kwaye emva koko i-multihead weigher yaqala ukusebenza; emva kwexesha elithile, xa ubunzima bomnatha bezinto ezikrwada kwi-hopper yokulinganisa buqhubeka buncipha kwaye bafikelela kwinqanaba lezinto ezincinci kwi-t2, ivalve yokukhupha yavulwa kwakhona, kwaye ixesha ukusuka kwi-t1 ukuya kwi-t2 yayingumsebenzi ixesha; emva kwexesha elithile, xa ubunzima bomnatha bezinto eziluhlaza kwi-hopper yokulinganisa buqhubeka bukhula kwaye bufike kwinqanaba eliphezulu lezinto eziphathekayo kwakhona ngexesha le-t3, i-valve yokukhupha ivaliwe, kwaye ixesha ukusuka kwi-t2 ukuya kwi-t3 lixesha lomjikelo ukukhupha kwakhona, njalo njalo. Ngethuba lexesha lokujikeleza kwe-force feeder, umlinganiselo wesantya we-screw conveyor ubekwe esweni ngokwesantya sokuhamba ngokukhawuleza ukuphumeza i-feeder ezinzileyo; ngexesha lomjikelo wokukhulula kwakhona, umlinganiselo wesantya somjikelo we-screw uya kugcina umlinganiselo wesantya ngaphambi kokuba kuqale ixesha lomjikelo. Guqula i-feeder kwindlela yokuhlola ukuhamba kwevolumu rhoqo.

Ngenxa yokuba isilinganisi se-multihead sidibanisa ubunzima obuguquguqukayo kunye nedatha engatshintshiyo, kwaye idibanisa i-feeder ephazamisekileyo kunye nokutya okuqhubekayo, isakhiwo kulula ukutywinwa, kwaye silungele ukulinganiswa kwezinto eziluhlaza ezifana nekhonkrithi, umgubo okhawulezayo, amalahle acoliweyo, ukutya. , iyeza, njl. Ubunzima kunye nokulawulwa kwe-seasoning, banokufikelela ukuchaneka okuphezulu kunye nomgca. 2. Imfuneko yesikimu soyilo lweeparamitha eziphambili zokusebenza kwe-multihead weigher Xa uyila iskimu se-multihead weigher, iiparitha eziphambili zokusebenza ezifana nokuphindaphinda kokukhutshwa, umthamo wokukhutshwa kwakhona, amandla i-hopper yokulinganisa, kunye nesantya sokukhutshwa kwakhona kufuneka kuthathelwe ingqalelo, ngaphandle koko i-multihead weigher ayiyi kusebenza ngokufanelekileyo emsebenzini. Umthengi uthenge i-multihead weigher kumenzi wesixhobo sokugcinwa kwesixhobo ukuze kuhlalutywe uphawu. Zii-3 100kg zokuvayisha kuphela ezithengiweyo. Emva kokusetyenziswa, kwafunyaniswa ukuba indawo ye-zero yayingazinzanga, kwaye ukuhamba ngokupheleleyo ngamanye amaxesha akuzange kubonise ulwazi kunye nezinye iimpazamo eziqhelekileyo.

Emva kokuba umenzi athumele umntu kwindawo, baqaphela ukuba izinto eziluhlaza zomthengi yi-boric acid, ukuxinana kwe-1510kg / m3, ukuhamba okupheleleyo ku-36kg / h kuphela, kunye nokuhamba okuqhelekileyo okuqhelekileyo ngu-21 ~ 24kg / h. Ukuhamba okupheleleyo kuncinci kakhulu, i-hopper ithatha ezintathu ze-100kg zobunzima beendawo zenkxaso yenzwa, kwaye umthamo we-hopper yohlalutyo mkhulu kakhulu. Umntu unokulandela imigaqo ecetyiswa ngamandla yamava omsebenzi angezantsi“Xa isixa somlotha sikhulu, i-frequency yokukhupha kwakhona ikhethwa njenge-15 ukuya kwi-20 amaxesha / h.”Ukuthwala, ubunzima bokukhutshwa kwakhona ngalunye yi-36/15 ~ 36/20, oko kukuthi, 1.9kg ~ 2.4kg. Ubunzima obunetha bezinto eziluhlaza ezithwalwa yinzwa nganye yobunzima bungaphantsi kwe-1 kg, kwaye uluhlu olufanelekileyo lokulinganisa malunga ne-0.5 ~ 1%.

Ngokuqhelekileyo, uluhlu olufanelekileyo lomlinganiselo wenzwa yokulinganisa kufuneka ubuncinane lube yi-10 ~ 30% okanye ngaphezulu, ukuze kuqinisekiswe umlinganiselo ochanekileyo. Ngokobunzima bempahla ekrwada ye-2.4kg kunye nobunzima bomnatha be-hopper kunye nezixhobo zokutyisa (ezifana ne-screw conveyor), ubunzima bubonke bumalunga ne-10kg. Ukuba iiseli zomthwalo ezintathu zisetyenzisiwe, uluhlu lokulinganisa lweseli nganye yomthwalo lunokukhethwa ukusuka kwi-5kg ~ 10kg. Oko kukuthi, uluhlu lokulinganisa lwe-sensor ye-100kg eyayalelwa ekuqaleni iba ngama-10-20 amakhulu ngokuphindwe kabini, okukhokelela ekuthembekeni okungahambi kakuhle kwe-multihead weigher kunye nokuchaneka okuphantsi kobunzima.

Eli tyala libonisa ukuba isicwangciso soyilo somlinganiso we-multihead kufuneka siphinde sihambelane nomgangatho wesikimu soyilo, kwaye iiparitha eziphambili zesixhobo somatshini kunye nokusebenza kwe-multihead weigher kufuneka kunqunywe emva kokubala. 3. Ukubalwa kweskimu soyilo lweeparamitha eziphambili zokusebenza kwe-multihead weigher 3.1 Ukubalwa kwe-discharge frequency Umfanekiso we-1 ucacisa ukusebenza kwe-multihead weigher. Inkqubo nganye yomjikelo ibandakanya yonke inkqubo yokukhutshwa, ngoko yintoni i-frequency discharge frequency? Kwi-multihead weigher, umlinganiselo omkhulu wokuhlala komjikelo we-force feeder kwinkqubo yomjikelo ngamnye (ixesha lokuhlala = umjikelo we-force feeder / umjikelezo wokukhupha kwakhona), ngcono, ngokubanzi kufuneka udlule i-10: 1. Oku kungenxa yokuba ukuchaneka kwexesha lomjikelo we-force feeder lidlula kakhulu ixesha lomjikelo wokuphinda ukhuphe. Okukhona ubuninzi bomjikelo we-force feeder, kokukhona kuphezulu ukuchaneka kukonke kwe-multihead weigher.

I-frequency ye-circulatory system ngexesha leyunithi ye-multihead weigher ibonakaliswe ngokubanzi njenge-frequency ye-circulatory system ngeyure xa inani lomlotha likhulu, oko kukuthi, amaxesha / h. Ngenxa yokuba i-precondition isekelwe kwisixa esikhulu sokutya kothuthu ngeyure, ukutya kothuthu ngexesha leyunithi (umzekelo, ngesekhondi) lixesha elingatshintshiyo. Okuncinci ukuphindaphinda kwenkqubo yokujikeleza, ubuninzi bezinto ezikhutshwayo ngexesha ngalinye, ubukhulu bomthamo kunye nobunzima bobunzima be-hopper yokulinganisa, kunye nokuncinci ukuchaneka kokunciphisa ubunzima kunye nokubala usebenzisa i-multi-range yokulinganisa inzwa; Okukhona ukuphindaphinda kwenkqubo yomjikelezo, Okukhona kusezantsi ubungakanani bokukhutshwa ngakunye, amandla amancinci kunye nobunzima bobunzima be-hopper yokulinganisa, kunye nokuphezulu kokuchaneka kokunciphisa ubunzima kunye nokubala usebenzisa inzwa yokulinganisa kunye noluhlu oluncinci lokulinganisa.

Nangona kunjalo, i-frequency yenkqubo yokujikeleza iphezulu kakhulu, izixhobo zomatshini wokutyisa ziqala kwaye ziyeke rhoqo, kwaye ibhodi yokulawula ye-multihead weigher idla ngokutshintsha phakathi kwexesha lomjikelo we-force feeder kunye nexesha lomjikelo wokondla kwakhona, onokuthi utshintshe. ayilunganga kakhulu. Iifrikhwensi zokukhupha kwakhona ezicetyiswayo ziboniswa kwiThebhile 1, kodwa eyona nto ibalulekileyo kwaye inconywa kakhulu ngamaza amathathu okukhupha phakathi. Njengomthetho wamava omsebenzi, uninzi lwe-software yenkqubo yokutya ilahleko-in-weight ifaneleke kakhulu kwizinto ezinomgubo kunye nezixhobo zegranular ezinobumanzi obumdaka. amaxesha/iyure.

Xa umyinge wokutya uthuthu ungaphantsi kwexabiso elikhulu lokutya uthuthu, ukuphindaphinda kokuphinda kuncitshiswe, ukwenzela ukuba izinga lokuhlala komjikelo we-feeder force likhulu, oluyinzuzo ngakumbi ukuphucula ukuchaneka. Njengomthetho wamava omsebenzi, ezinye izicelo ezinezinga eliphantsi kakhulu lokuhamba kwe-feeder, nangona umthamo we-hopper umncinci kakhulu, usengakwazi ukugcina izinto eziluhlaza kwiyure enye okanye ixesha elide lokutyisa, kwaye ixesha lokutya kwakhona lidlula iyure enye. . Lo mzekelo ulandelayo: Ukuqukuqela okupheleleyo kwe-feeder enkulu yi-2kg/h. Umlinganiselo wemfumba yempahla ekrwada yi-803kg/m3. Ukuhamba kukonke kwesondlo somthamo omkhulu ngu-2/803=0.0025m3/h. Ukuba umthamo we-hopper yi-0.01m3 (ilingana ne-25b250m×25b250m×Ubungakanani be-cube hopper efana ne-25b250m), ukusetyenziswa kwempahla ekrwada eyaneleyo ye-2h ~ 3h, kwaye isixa ngasinye sokutya singaphantsi kwe-10kg, ngoko akukho mfuneko yokutya okuzenzekelayo, ukutya kwenkonzo yezandla kunokuqwalaselwa kwimveliso kunye nemimiselo yokuvelisa, kodwa iyonke. ukuhamba kumgca ngaphantsi kancinci.

3.2 Ifomula yokubala umthamo wokukhutshwa kwakhona uye wakhetha ukuphindaphinda kokukhutshwa kwakhona, kwaye ke umthamo wokukhutshwa kwakhona kunye nomthamo opheleleyo we-feeder ungabalwa. Ngokohlalutyo lweempawu ze-multihead weigher: ireyithi yokuhamba iyonke ye-feeder enkulu yi-275kg / h, ubuninzi bobuninzi bezinto eziluhlaza yi-485kg / m3, kwaye isantya sokuhamba sisonke se-270/480= 0.561m3/h. Ubuninzi bezinto eziphathekayo bukhethwa ngamaxesha angama-15 / h. Indlela yokubala yomthamo wokukhutshwa kwakhona kukuba: umthamo wokukhutshwa kwakhona = inani elikhulu lomlotha (kg / h)÷Ubuninzi (kg/m3)÷Ukukhupha kwakhona i-frequency (i-re-discharge frequency / h) Kulo mzekelo, ukukhupha kwakhona umthamo = 270÷480÷15=0.0375m33.3 Ukubalwa kobunzima behopper Umthamo wehopha yoweyishi kwisikimu soyilo ngokungathandabuzekiyo uya kudlula umthamo obaliweyo wokukhupha kwakhona. Oku kungenxa yokuba kuyimfuneko ukuqwalasela ukuba i-hopper yokulinganisa ayinakuthintelwa xa ukukhutshwa kwakhona kuqalwa. Kukwakho nezinye“Imathiriyeli ekrwada eseleyo”kwaye umphezulu we-hopper unokugcinwa okungenakwenzeka ukuba kuzaliswe“Vula isithuba”, ukuba nganye i-akhawunti ye-20%, ngoko umthamo wokukhupha kwakhona uhlukaniswe ngu-0.6, kwaye umthamo ofunekayo we-hopper unokufumaneka, kwaye umthamo wokugqibela we-silo kufuneka ube ne-glossy ngokomthamo we-silo ogqityiweyo. Indlela yokubala yokukhupha kwakhona umthamo: ubungakanani bomthamo wehopper = ukukhupha kwakhona umthamo÷Apho k: k isalathiso somthamo obaliweyo we-hopper, enokuthi ibe yi-0.4 ~ 0.7, kwaye i-0.6 icetyiswa ngamandla.

Kulo mzekelo, Weigh Hopper Capacity = 0.0375÷0.6=0.0625m3 Ukuba umthamo wesilelo sokubunjwa uneenkcukacha ezifana ne-0.6m3, 0.2m3, 1.b2503, njl., kufuneka ibengezele ukuya kuthi ga kwi-0.08m3, kwaye umthamo we-hopper yokulinganisa kufuneka ube yi-0.08m3. 3.4 Ireyithi yokukhupha ibalwa kwakhona ngenxa ye-multihead weigher Ngexesha lokuphinda likhutshwe, i-low-precision constant-capacity method feeder ikhethiwe, ngoko ke ukukhutshwa kwakhona kwesantya se-vibrating feeder kuchazwe ngokukhawuleza (ngokubanzi, kufuneka iqhutywe ngaphakathi kwe-5s ~ 20s). Indlela yokubala ireyithi yokukhupha kwakhona: ireyithi yokukhupha kwakhona = [ukukhupha kwakhona umthamo (m3)÷Ixesha lokukhupha kwakhona (s)×60(s/min)]+[Uhambo lulonke lwesixhasi somthamo omkhulu (m3/h)÷60 (min/h)] Kwifomula yesi-2, izinga lokukhutshwa kwakhona liquka izinto ezimbini.
