Nthawi yomweyo kuthamanga kwathunthu ndi kutulutsa kwathunthu. Mfundo yofunikira ndi makina olemera a static data net weight and equipment, teknoloji yolemera ya static data warehouse sikelo imasankhidwa, ndipo malo osungiramo katundu wa cell net weight amagwiritsidwa ntchito. Komabe, mu gulu lowongolera la multihead weigher, kuti mupeze bwino kulemera kwa ukonde komwe kunatayika pa nthawi ya unit ya sikelo yosungiramo zinthu zopangira, ndikofunikira kuyeza nthawi yomweyo kuchuluka kwazinthu zopangira.

Kumanzere kwa Chithunzi 1 ndi chithunzi cha sikelo yosowa kulemera. Pamene zopangira mu nkhokwe zolemetsa za ukonde zilibe zida zofunikira, valavu yamagetsi imatha kutsegulidwa. Pamene malo ochulukirapo azinthu zopangira afika, valavu yopangira zinthu imatsekedwa, ndipo malo osungiramo katundu wa ukonde amathandizidwa ndi ukonde wosowa sikelo. Lozani. Kuti muyeso ukhale wolondola kwambiri, mbali zakumwamba ndi zapansi za nyumba yosungiramo katundu zimagwirizanitsidwa molingana ndi ndime zofewa ndi zolowera ndi zotuluka, ndi kutsogolo ndi kumbuyo, kumanzere ndi kumanja makina ndi zipangizo ndi kulemera kwa ukonde wa zopangira mu. sichiwonjezera ku nkhokwe yoyezerapo. Mbali yakumanja ya Chithunzi 1 ndikuwona dongosolo la njira yonse yoperekera mosalekeza. Pali njira yozungulira njira yonse yoperekera mosalekeza (zambiri pachithunzichi zikuwonetsa machitidwe atatu ozungulira).

Dongosolo lililonse lozungulira limakhala ndi nthawi za 2: pomwe malo osungiramo zinthu zolemetsa ukonde ndikuchepetsa nyumba yosungiramo zinthu, kulemera kwazinthu zopangira muukonde wosungiramo zinthu kumachulukidwa, ndipo pomwe malo opitilira muyeso afika pa t1, zopangira. valavu yatsekedwa, ndipo wononga conveyor akuyamba kutulutsa zopangira, ndipo kulemera kwa ukonde kumatayika panthawiyi. Sikelo ikayamba kugwira ntchito kwakanthawi, kulemera kwazinthu zopangira muukonde wosungiramo zinthu kumachepa. Pamene malo ocheperako akufika pa t2, valavu yazitsulo idzatsegulidwanso. Nthawi yochokera ku t1 mpaka T2 imapereka nthawi yozungulira yamtundu wa mphamvu. Pakapita nthawi, kulemera kwa ukonde wa zinthu zopangira mu nkhokwe yolemetsa kumawonjezeka. Nthawi ya T3 ikafikanso pamalo apamwamba kwambiri, valavu yopangira zinthu imatsekedwa, ndipo nthawi yochokera ku t2 mpaka t3 imabwerezedwanso mu nthawi yanthawi yoperekera mphamvu, ndipo kuchuluka kwa liwiro la screw conveyor kumayang'aniridwa molingana ndi kutuluka kwanthawi yomweyo. , kuti mukwaniritse njira yokhazikika yoperekera. Pa nthawi, chiŵerengero cha liwiro la wononga conveyor amakhalabe liwiro chiŵerengero atangotsala pang'ono chiyambi cha mkombero nthawi ndipo sasintha, ndipo amaperekedwa ndi nthawi zonse voliyumu kuwunika otaya njira. Chifukwa choyezera chamtundu wamtundu wambiri chimaphatikiza masekeli amphamvu ndi ma data osasunthika, ndikuphatikiza kudyetsa kosokonekera ndi kudyetsa kosalekeza, kapangidwe kake kamakhala kothandiza kusindikiza, ndipo ndi koyenera, konkire, ufa wa quicklime, malasha opunthidwa, chakudya, mankhwala ndi zida zina zazing'ono. Kuyeza ndi kudyetsa ntchito kungathe kukwaniritsa masekeli apamwamba ndi linearity. 2multihead weigher imagwira ntchito pakufunika kwa dongosolo lalikulu la mapangidwe.

Popanga sikelo yokhala ndi kulemera kwaukonde kosowa, onetsetsani kuti mwaganizira magawo akuluakulu ogwiritsira ntchito monga kudyetsa pafupipafupi, kuchuluka kwa kudyetsanso, kudyetsanso mphamvu yosungiramo katundu, komanso kuchuluka kwa kudyetsanso. Kupanda kutero, sikelo yolemetsa yosowa sikungagwire ntchito bwino. Mwachitsanzo, kasitomala adagula choyezera chamitundu yambiri kuchokera kwa wopanga kuti azikonza zida zapamalo. Pa nthawi yogula, ma sensor 3 100kg okha ndi omwe adagulidwa.

Wopangayo adatumiza munthu pomwepo kuti adziwe kuti zopangira za kasitomala ndi yankho la boric acid, kachulukidwe kake ndi 1510kg/m3, otaya pazipita okwana 36kg/h, ndipo wamba otaya okwana ndi 21 ~ 24kg/h. Kuthamanga kwathunthu ndi kochepa kwambiri, hopper imagwiritsa ntchito mfundo zitatu zothandizira sensa ya 100kg, ndipo hopper yowunikira imakhala ndi mphamvu zambiri. Ndivuto losagwirizana ndi sayansi pakusankha zitsanzo. Vuto lina ndilakuti hopper imalumikizidwa ndi makina okhala ndi gwero logwedezeka pakuyika. Titha kusankha 15 ~ 20 nthawi / h malinga ndi mfundo zotsatirazi zomwe zimalimbikitsidwa kwambiri pamene kufunika kuli kokulirapo, ndipo kulemera kwamtundu uliwonse ndi 36/15 ~ 36/20, ndiko kuti, 1.9kg ~ 2.4kg, Kulemera konse kwazinthu zopangira zonyamula ndi sensa iliyonse yolemetsa ndi yochepera 1 kg, ndipo miyeso yoyenera ndi pafupifupi 0.5 ~ 1%.

Nthawi zambiri, kuyeza koyenera kwa sensa yolemera kuyenera kukhala osachepera 10-30% kuti mutsimikizire kulemera kolondola. Malinga ndi kulemera kwa ukonde wa zopangira 2.4kg ndi kulemera kwa ukonde wa nyumba yosungiramo zinthu zopangira ndi makina ndi zida zopangira (screw conveyor, etc.), kulemera okwana pafupifupi 10kg. Masensa atatu olemera akagwiritsidwa ntchito, muyeso wamtundu uliwonse wolemera ukhoza kusankhidwa kuchokera ku 5kg mpaka 10kg. Mwanjira ina, kuchuluka kwa sensa ya 100kg yogulidwa kumachulukitsidwa ndi 10 ~ 20 nthawi, kudalirika kwa choyezera chamitundu yambiri ndikosauka, ndipo kuyeza kwake kumakhala kochepa.

Mlanduwu ukuwonetsa kuti dongosolo la kapangidwe ka multihead weigher liyeneranso kutsatizana ndi kapangidwe kake, ndipo magawo akulu a zida zamakina ndi magwiridwe antchito a multihead weigher sangathe kuganiziridwa popanda kuyeza. 3Multihead Weigher Opareshoni Zoyambira Zowerengera Zopangira Mapangidwe. 3.1 Kuwerengera pafupipafupi kudyetsa.

Kwa choyezera chamagulu ambiri, chiŵerengero chokulirapo cha kuchuluka kwa mphamvu yamagetsi (nthawi yowerengera = kuchuluka kwa mphamvu / kuzungulira kwapang'onopang'ono) mumayendedwe aliwonse ozungulira, ndibwino, nthawi zambiri kuyenera kupitilira 10: 1. Izi ndichifukwa choti mtundu wa mphamvuyo umapereka nthawi yozungulira molunjika kwambiri kuposa nthawi yobwereza, ndipo ngati mtundu wa mphamvuyo umapereka nthawi yozungulira, ndiye kuti woyezera mutu wambiri amakwera kwambiri. Ma frequency a circulatory system pa nthawi ya unit ya multihead weigher nthawi zambiri amawonetsedwa ngati ma frequency a circulatory system pa ola pomwe kufunikira kuli kwakukulu, ndiko kuti, nthawi / h.

Kutengera kuchulukirachulukira pa ola ngati muyezo, nthawi yofunikira nthawi zonse pa nthawi ya unit (mwachitsanzo, pa sekondi iliyonse) ndiye chofunikira. Kuchepa kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake pafupipafupi kwa kayendedwe ka kayendedwe kake, kuchuluka kwa kudyetsa nthawi zonse. M'munsi mwake, mphamvu yaing'ono ndi kulemera kwa ukonde wosungira katundu, komanso kukwezera kulondola kwakugwiritsa ntchito kachulukidwe kakang'ono ka maselo olemetsa kuti muyese kulemera kwake. Komabe, mafupipafupi a dongosolo lozungulira ndilokwera kwambiri, makina odyetsera makina odyetsera nthawi zambiri amathetsedwa, ndipo gulu lolamulira la multihead weigher nthawi zambiri limasintha pakati pa nthawi yodyetsa mphamvu ndi nthawi ya refeeding, ndipo si yabwino kwambiri.

Monga momwe zimachitikira nthawi zonse, dziko lopanda kulemera limapereka mapulogalamu a pulogalamu, makamaka kwa powdery ndi particles bwino fluidized, maulendo obwereza amasankhidwa ngati 15 ~ 20 nthawi / ola pamene kufunika kuli kwakukulu. Pamene kufunikira kuli kochepa kusiyana ndi kufunidwa kwakukulu, kuchuluka kwa kubwereketsanso kumachepetsedwa, ndipo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Kupatula kukhazikika kwazomwe zimagwira ntchito, mapulogalamu ena omwe amapereka otsika otsika kwambiri, ngakhale mphamvu yosungiramo katunduyo ndi yaying'ono kwambiri, imatha kusungabe zida zomwe zimaperekedwa kwa ola lopitilira 1, komanso nthawi yopereka nthawi yopitilira ola limodzi.

Milandu yotsatirayi: Yaikulu imapereka otaya okwana 2kg/h. Kuchuluka kwazinthu zopangira ndi 803kg/m3. Kuchuluka kwa kuchuluka kwa chakudya chokulirapo ndi 2/803=0.0025m3/h.

Ngati mphamvu yosungiramo katundu ndi 0.01m3 (pafupifupi yofanana ndi 250Mm×250 mm×Kukula kwa nyumba yosungiramo mita ya kiyubiki ngati 250Mm) ndi yokwanira 2h ~ 3h yogwiritsira ntchito zopangira, ndipo kugwiritsa ntchito kulikonse sikudutsa 10kg, kotero zopangira zokha sizifunikira, ndipo zida zopangira anthu zitha kuganiziridwa. Malamulo opangira zinthu, koma kuchuluka kwa kayendedwe kake kumakhala kotsika pang'ono . 3.2 Werenganinso kuchuluka kwa chakudya. Pambuyo posankha mafupipafupi owonjezeredwa, ndizotheka kuyeza voliyumu yowonjezeredwa ndi kuchuluka kwa voliyumu yowonjezera.

Tengani choyezera mitu yambiri monga chitsanzo: chokulirapo chimapereka otaya okwana 270KG/ola. Kuchuluka kwazinthu zopangira ndi 485kg/m3. Kuchuluka kwa kuchuluka kwa chakudya chokulirapo ndi 270/480=0.561m3/h.

Pachiwongoladzanja chachikulu choperekera, maulendo obwereza amasankhidwa kukhala 15 nthawi / h. Njira yowerengera yoyikanso voliyumu: kuyikanso voliyumu = kuchuluka kokulirapo (kg/h)÷Kachulukidwe (kg/m3)÷Kulowetsanso pafupipafupi (maulendo obwereza / h) Pankhaniyi, voliyumu yoyikanso = 270÷480÷15 = 0.0375m3. 3.3 Kuwerengera kuchuluka kwa malo osungira katundu.

Kuchuluka kwa malo osungiramo katundu wa net wa pulani yamapangidwe kuyenera kupitilira kuchuluka kowerengeredwa kosungirako kulemera kwa net. Izi zili choncho chifukwa nyumba yosungiramo zinthu zolemetsa za net idzakhala ndi zida zotsalira komanso malo aulere pamwamba pa nyumba yosungiramo zinthu zakale pomwe malo osungiramo zinthu zolemetsa ukonde ayamba nkhokwe zolemetsa. Ngati chilichonse chili ndi 20%, ndipo kuchuluka kwa malo osungiramo katundu kumagawidwa ndi 0.6, mphamvu yosungiramo zinthu zofunika ingapezeke.

Voliyumu yomaliza yosankhidwa yosungiramo zinthu zolemetsa iyenera kukhala yonyezimira molingana ndi voliyumu yosungiramo yokhazikika. Njira yowerengera yotsitsanso voliyumu: Netweight Warehouse capacity = net weight volume÷k. Mu chilinganizo: k ndiye chilolezo chowonjezera chosungiramo zinthu zopangira, chomwe chingakhale 0.4 ~ 0.7, ndipo 0.6 ikufunsidwa.

Mu chitsanzo ichi, mphamvu yosungiramo katundu wolemera = 0.0375÷0.6 = 0.0625m3. Pamene voliyumu ya nyumba yosungiramo zinthu zooneka ngati 0.6m3, 0.8m3, 1.0M3 ndi zina ndi zitsanzo zina, gloss ayenera kukhala 0.08m3 m'mwamba, ndi mphamvu yosungiramo katundu ayenera kukhala 0.08m3. 3.4 Yezerani kuchuluka kwa kukhazikitsanso.

Kuyeza kwamitundu yambiri kumaperekedwa ndi njira yochepetsetsa yokhazikika yokhazikika mu nthawi yobwezeretsanso, kotero kuti kulowetsedwa kwa makina otsitsimula kumatchulidwa kuti ndi mofulumira (kawirikawiri, ziyenera kuyendetsedwa mkati mwa 5s ~ 20s). Njira yowerengera yotsitsanso: recapitalization rate = [recapitalization volume (m3)÷Nthawi yobwezeretsanso (s)×60(s/min)]+[chikulu cha ndalama zogulira ndalama zonse (m3/h)÷60(min/h)] Mu Equation 2, mlingo wowonjezeranso uli ndi zinthu 2 zatsopano, chinthu chatsopano choyamba ndi mlingo wowonjezera potengera voliyumu yowonjezeranso, ndipo chinthu chatsopano chachiwiri nthawi zambiri chimanyalanyazidwa ndi anthu ambiri, kusonyeza kuti chimodzimodzi Mlingo wa Kuwonjezera nthawi, zopangira kuti ayenera kudzaza gawoli pamene anawonjezera kachiwiri. Malinga ndi mtengo wake, kuchuluka kwa kudyetsanso kumakhala pafupifupi nthawi 30 kuposa kuchuluka kwake. Mwa kuyankhula kwina, molingana ndi mtengo uwu, poyerekezera kuchuluka kwa chakudya chamtundu wina wosowa masikelo, akhoza kuyerekezedwa pa 25-40 nthawi yowonjezera yowonjezera. .
