Umbhali: Smartweigh–Multihead Weighter

I-Multihead weigher (I-Loss-in-weightfeeder) lucazululo lobungakanani bobunzima bokubonelela ngezixhobo, ezisetyenziswa ikakhulu, i-multihead weigher isetyenziselwa ubunzima obuqhubekayo obuqhubekayo kuyo yonke inkqubo, inokuqhuba ubunzima obunenethi kunye nohlalutyo lobungakanani bemathiriyeli ekrwada ekufuneka ibe nayo. ibonelelwa ngokuqhubekayo, kwaye ibonise ulwazi malunga nemathiriyeli ekrwada. Ukuqukuqela okupheleleyo kwangoko kunye nokuqukuqela okupheleleyo. Umgaqo osisiseko ngumatshini wobunzima bedatha ye-static kunye nezixhobo, itekhnoloji yobunzima bomnatha we-static data warehouse scale ikhethiwe, kwaye i-cell net weight weight isetyenziswa. Nangona kunjalo, kwiphaneli yokulawula ye-multihead weigher, ukuze ufumane bhetele ubunzima obulahlekileyo ngexesha leyunithi yesikali sokugcina impahla ekrwada, kuyimfuneko ukulinganisa ukuhamba okupheleleyo kwangoko kwezinto eziluhlaza.

Icala lasekhohlo loMzobo woku-1 ngumzobo wesakhelo sobunzima obungekhoyo. Xa izinto eziluhlaza kwindawo yokugcina ubunzima bomnatha zingenazo izinto eziyimfuneko ezifunekayo, ivalve yempahla ekrwada inokuvulwa. Xa ubuninzi bendawo ekrwada bufikelelwe, ivalve yempahla ekrwada ivaliwe, kwaye indawo yokugcina ubunzima bomnatha ixhaswa sisikali esilahlekileyo sobunzima. Inqaku. Ukuze wenze umlinganiso uchaneke ngakumbi, amacala aphezulu nangaphantsi kwendawo yokugcina ukulinganisa adityaniswe ngokweendlela ezithambileyo zokungena kunye nokuphuma, kunye nangaphambili nangasemva, ngasekhohlo nasekunene koomatshini kunye nezixhobo kunye nobunzima obunetha bezinto ezikrwada ngaphakathi. ayongezi kwisixhobo sokulinganisa. Icala lasekunene loMzobo 1 yimbono yesicwangciso sayo yonke inkqubo yokubonelela ngokuqhubekayo. Kukho inkqubo yomjikelezo wenkqubo yonke yokubonelela ngokuqhubekayo (ulwazi olukumzobo lubonisa iinkqubo ze-3 cycle).

Inkqubo nganye yomjikelo iquka amaxesha ama-2 okujikeleza: xa i-warehouse yobunzima bokunciphisa i-warehouse, ubunzima bobuncwane bezinto eziluhlaza kwi-warehouse ye-net weight iyanda, kwaye xa ubuninzi bendawo ekrwada bufikelelwa kwi-t1, i-raw material. ivalve ivaliwe, kwaye i-screw conveyor iqala nje ukukhupha izinto eziluhlaza, kwaye ubunzima bomnatha bulahlekile ngeli xesha. Emva kokuba isikali siqale ukusebenza ixesha elithile, ubunzima obunetha bezinto eziluhlaza kwindawo yokugcina ubunzima buya kuncipha. Xa ubuncinci bendawo ekrwada bufikelelwe kwi-t2, ivelufa yezinto ekrwada iya kuvulwa kwakhona. Ixesha elivela kwi-t1 ukuya kwi-t2 linika ixesha lokujikeleza kohlobo lwamandla. Emva kwexesha elithile, ubunzima obunetha bezinto eziluhlaza kwi-warehouse yobunzima bomnatha buya kwanda. Xa ixesha le-t3 lifikelela kwindawo ephezulu yezinto ekrwada kwakhona, ivalve yezinto ekrwada ivaliwe, kwaye ixesha ukusuka kwi-t2 ukuya kwi-t3 liphinda liphindwe kwixesha lomjikelo lonikezelo lwamandla, kwaye umlinganiselo wesantya se-screw conveyor ujongwa ngokuhambelana nokuhamba kwangoko. , ukuze kuphunyezwe umjikelo ozinzileyo wonikezelo. Ngethuba lexesha, umlinganiselo wesantya we-screw conveyor ugcina umlinganiselo wesantya ngaphambi nje kokuqala kwexesha lomjikelezo kwaye awutshintshi, kwaye unikezelwa yindlela yokujonga umthamo oqhubekayo. Ngenxa yokuba i-multihead weigher idibanisa ngokusondeleyo ubungakanani obuguquguqukayo kunye nedatha engatshintshiyo, kwaye idibanisa ngokusondeleyo ukondla okuphazamisekileyo kunye nokutya okuqhubekayo, isakhiwo sikulungele ukutywinwa, kwaye sifanelekile kwikhonkrithi, umgubo okhawulezayo, amalahle acoliweyo, ukutya, amayeza kunye nezinye izinto ezincinci ezikrwada. Umsebenzi wokulinganisa kunye nokutya kunokufikelela ukuchaneka okuphezulu kunye nomgca. I-2 ye-multihead weigher isebenza kwimfuno yeskimu soyilo lweparameter ephambili.

Xa uyila isikali esinesisindo sobunzima obulahlekileyo, qiniseka ukuba uthatha ingqalelo kwiiparamitha eziphambili zokusebenza ezifana nokuphindaphinda kokutya, umthamo wokutya kwakhona, umthamo wokutya kwakhona, kunye nesantya sokutya kwakhona. Ngaphandle koko, isikali esilahlekileyo sobunzima asiyi kusebenza kakuhle. Umzekelo, umthengi uthenge i-multihead weigher kumenzi wokugcinwa kwezixhobo kwindawo. Ngexesha lokuthenga, kuphela i-3 100kg yokuvavanya ubunzima obuthengiweyo.

Umenzi wathumela umntu kwangoko ukuba azi ukuba izinto eziluhlaza zomthengi ziyisisombululo se-boric acid, ukuxinana kwe-1510kg / m3, ukuhamba okupheleleyo kwe-36kg / h, kunye nokuhamba okuqhelekileyo okuqhelekileyo yi-21 ~ 24kg / h. Ukuhamba okupheleleyo kuncinci kakhulu, i-hopper isebenzisa ezintathu ze-100kg zenkxaso ye-sensor sensor points, kunye ne-hopper yohlalutyo inomthamo omkhulu. Yingxaki engeyoyenzululwazi ekukhetheni imodeli. Enye ingxaki kukuba i-hopper iqhagamshelwe kumatshini onomthombo wokungcangcazela ngexesha lofakelo. Sinokukhetha i-15 ~ 20 amaxesha / h ngokwemigangatho elandelayo yamava omsebenzi acetyiswayo kakhulu xa imfuno inkulu, kwaye ubunzima bomnatha wonikezelo ngalunye olongezelelweyo 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 lokulinganisa inzwa yobunzima kufuneka ubuncinane bube yi-10 ~ 30% ukuqinisekisa ubungakanani obuchanekileyo. Ngokobunzima obunetha bezinto eziluhlaza 2.4kg kunye nobunzima bokugcina impahla ekrwada kunye noomatshini bezinto ezikrwada kunye nezixhobo (i-screw conveyor, njl.), ubunzima bubonke bumalunga ne-10kg. Xa kusetyenziswa izinzwa ezintathu zobunzima, uluhlu lokulinganisa lwenzwa nganye yesisindo lunokukhethwa ukusuka kwi-5kg ukuya kwi-10kg. Ngamanye amazwi, ubuninzi be-sensor ye-100kg ethengiweyo inyuswe ngamaxesha angama-10 ~ 20, ukuthembeka kwe-multihead weigher akubi, kwaye ukuchaneka kokulinganisa kuphantsi.

Eli tyala libonisa ukuba isicwangciso soyilo lwe-multihead weigher kufuneka kwakhona ihambelane nomgangatho wesikimu soyilo, kwaye iiparitha eziphambili zesixhobo somatshini kunye nokusebenza kwe-multihead weigher ayikwazi ukugqitywa ngaphandle kokulinganisa. I-3 ye-multihead weigher operation eziphambili iiparameters zeskimu soyilo lokubala. 3.1 Ukubalwa kwamaxesha okutyiswa.

Kwi-multihead weigher, umlinganiselo omkhulu wokujikeleza kwamandla (umlinganiselo wexesha = umjikelo wokunikezelwa kwamandla / umjikelezo wokunikezela kwakhona) kwinkqubo nganye yokujikeleza, bhetele, ngokuqhelekileyo kufuneka idlule i-10: 1. Oku kungenxa yokuba uhlobo lwamandla lunika ixesha lomjikelo ngokuchaneka okuphezulu kakhulu kunexesha lomjikelo wokubuyisela kwakhona, kwaye ixesha elide uhlobo lwamandla lubonelela ngexesha lomjikelo, luphezulu ukuchaneka okupheleleyo kwe-multihead weigher. I-circulatory system frequency ngeyunithi yeyunithi ye-multihead weigher ibonakaliswa ngokubanzi njenge-circulatory system frequency ngeyure xa imfuno inkulu, oko kukuthi, amaxesha/h.

Ukuthatha imfuno enkulu ngeyure njengomgangatho, ixesha lemfuno elingaguqukiyo ngokweyunithi yexesha (umzekelo, ngesekhondi) ngumqathango wangaphambili. Okukhona kuncinci ukuphindaphindeka kwenkqubo yokujikeleziswa, kokukhona ubuninzi bokutya ngakunye, kokukhona umthamo kunye nobunzima obushiyekileyo bendawo yokugcina ubunzima, kokukhona usezantsi ukuchaneka kokulinganisa imeko engenabunzima ngokusebenzisa amanqanaba amaninzi eeseli zomthwalo, kokukhona Ukuphindaphinda kwenkqubo yokujikeleza, ubukhulu bexabiso lokutya ngexesha ngalinye. Ephantsi kwayo, incinci umthamo kunye nobunzima obunetha be-warehouse yobunzima bomnatha, kwaye iphezulu ukuchaneka kokusebenzisa inani elincinci leeseli zomthwalo ukulinganisa imeko engenabunzima. Nangona kunjalo, ukuphindaphinda kwenkqubo yomjikelo kuphezulu kakhulu, izixhobo zomatshini wokutyisa zihlala zipheliswa, kwaye iphaneli yokulawula ye-multihead weigher idla ngokutshintsha phakathi kwexesha lomjikelo wokutya kwamandla kunye nexesha lomjikelo wokubuyisela, kwaye akulunganga kakhulu.

Njengesiqhelo samava omsebenzi, ininzi yelizwe elingenasisindo libonelela ngesofthiwe yenkqubo, ngokukodwa kwi-powdery kunye ne-particlely fluidized particles, i-frequency of resupply ikhethwa njenge-15 ~ 20 amaxesha / iyure xa imfuno inkulu. Xa imfuno iphantsi kunemfuno enkulu, ukuphindaphinda kokunikezelwa kwakhona kuyancitshiswa, kwaye umjikelo wokunyanzeliswa kohlobo lokunyanzeliswa kwe-akhawunti yomlinganiselo omkhulu, ohambelana nokuphucula ukuchaneka. Ngaphandle kokuqheleka kwamava omsebenzi, ezinye izicelo ezibonelela ngokuqukuqela okuphantsi kakhulu, nangona umthamo we-warehouse umncinci kakhulu, usenokugcina izinto ezikrwada ezibonelelwe ngaphezu kweyure enye, kunye nexesha lokubonelela ngaphezulu kweyure enye.

Ezi meko zilandelayo: Enkulu inika ukuhamba okupheleleyo kwe-2kg / h. Umlinganiselo wokubekwa kwezinto ekrwada yi-803kg/m3. Ukuqukuqela komthamo omkhulu wokutya ngu-2/803=0.0025m3/h.

Ukuba indawo yokugcina impahla yi-0.01m3 (malunga ne-250Mm×250mm×Ubungakanani be-cubic meter warehouse efana ne-250Mm) yanele i-2h ~ 3h yokusetyenziswa kwezinto eziluhlaza, kwaye ukusetyenziswa kwezinto eziluhlaza nganye akudluli kwi-10kg, ngoko ke izinto ezizenzekelayo ezizenzekelayo azifunwa, kwaye izinto ezisetyenziswayo zingaqwalaselwa. Imimiselo yokuvelisa, kodwa i-flow flow linearity iyonke iphantsi kancinci. 3.2 Bala umthamo wokutyisa kwakhona. Emva kokukhetha i-frequency refill, kunokwenzeka ukulinganisa umthamo wokugcwalisa kunye nomthamo opheleleyo wokubonelela.

Thatha i-multihead weigher njengomzekelo: inkulu inika ukuhamba okupheleleyo kwe-270KG ngeyure. Ubuninzi bobuninzi bemathiriyeli ekrwada yi-485kg/m3. Ukuqukuqela komthamo omkhulu wokutya ngu-270/480=0.561m3/h.

Kwizinga elikhulu lokuhanjiswa, ukuphindaphinda kokunikezelwa kwakhona kwakhethwa ukuba kube ngamaxesha angama-15 / h. Indlela yokubala yokulayisha kwakhona umthamo: ukulayishwa kwakhona kwevolumu = isixa esikhulu sokongeza (kg/h)÷Ubuninzi (kg/m3)÷Ukungena kwakhona rhoqo (i-re-entry frequency / h) Kule meko, umthamo wofakelo kwakhona = 270÷480÷15=0.0375m3. 3.3 Ubalo lwesakhono sobunzima obushiyekileyo.

Ubungakanani obushiyekileyo bendawo yokugcina impahla yesicwangciso soyilo kufuneka bugqithe ubungakanani obubaliweyo bomthamo wogcino lwenethi. Oku kungenxa yokuba i-net weight warehouse ngokuqinisekileyo iya kuba nezixhobo eziseleyo kunye nesithuba esikhululekileyo phezulu kwindawo yokugcina iimpahla xa i-net weight warehouse iqala i-net weight warehouse. Ukuba nganye i-akhawunti ye-20%, kwaye umthamo we-net weight warehouse wahlulwe nge-0.6, umthamo oyimfuneko wokugcinwa kwezinto unokufumaneka.

Umthamo wokugqibela okhethiweyo we-net wobunzima bokugcina kufuneka ubengezela ngokuhambelana nomthamo osisigxina wendawo yokugcina impahla. Indlela yokubala yokulayisha kwakhona umthamo: umthamo we-net wobunzima obunzima = umthamo we-net wobunzima÷k. Kwifomula: k luqikelelo lwesalathiso sentshiyekela yendawo yokugcina impahla ekrwada, enokuba yi-0.4 ~ 0.7, kunye ne-0.6 ecetywayo.

Kulo mzekelo, umthamo we-net weight warehouse = 0.0375÷0.6=0.0625m3. Xa umthamo wendawo yokugcina impahla eyi-0.6m3, 0.8m3, 1.0M3 kunye nezinye iinkcukacha kunye neemodeli, iglosi kufuneka ibe yi-0.08m3 phezulu, kunye nomthamo wendawo yokugcina impahla kufuneka ibe yi-0.08m3. 3.4 Linganisa izinga lofakelo kwakhona.

I-weigher ye-multihead inikezelwa yindlela ephantsi yokuchaneka komthamo ochanekileyo kwixesha lokuphinda ulayishe kwakhona, ngoko ke izinga lokulayishwa kwakhona komatshini wokulayisha kwakhona lichazwe ngokukhawuleza (ngokubanzi, kufuneka lilawulwe ngaphakathi kwe-5s ~ 20s). Indlela yokubala yokulayisha kwakhona ireyithi: irecapitalisation rate = [recapitalization volume (m3)÷Ixesha lotyalo-mali ngokutsha (s)×60(s/min)]+[umthamo omkhulu wotyalo-mali lwenkunzi yemali iyonke ukuhamba (m3/h)÷60(min/h)] Kwi-Equation 2, umlinganiselo wokongezwa kwakhona uquka izinto ezi-2 ezintsha, into yokuqala entsha yireyithi yokongeza esekelwe kumthamo wokongeza kwakhona, kwaye into yesibini entsha idla ngokungahoywa ngabantu abaninzi, ebonisa ukuba okufanayo Umlinganiselo wokongezwa kwexesha, imathiriyeli ekrwada ekufuneka igcwalise le nxalenye xa yongezwa kwakhona. Ngokwexabiso, ireyithi yokondla kwakhona malunga namaxesha angama-30 kumlinganiselo omkhulu wokongezwa. Ngamanye amazwi, ngokweli xabiso, xa kuqikelelwa umlinganiselo wokutya kwakhona kwezinye izikali ezilahlekileyo zobunzima, unokuqikelelwa ngamaxesha angama-25-40 umlinganiselo omkhulu wokongezwa. .
