Mfundo yophatikiza mapasa mbiya mbiya

Kutsegula makina mbiya gawo

Mapangidwe ena a mbiya amapereka kasinthidwe kapadera ka ma twin screw extruders.Tikaphatikiza mbiya iliyonse ndi kasinthidwe koyenera, tidzachita kafukufuku wamba komanso wozama wamtundu uliwonse wa migolo iyi kuti ugwire ntchito ku gawo la extruder.

Chigawo chilichonse cha mbiya chimakhala ndi njira yooneka ngati 8 yomwe phula la screw limadutsa.Mgolo wotseguka uli ndi njira zakunja zololeza kudyetsa kapena kutulutsa zinthu zomwe zimawonongeka.Mapangidwe a mbiya otsegukawa atha kugwiritsidwa ntchito podyetsa ndi kutulutsa mpweya, ndipo amatha kuyikidwa paliponse pakuphatikizana kwa migolo yonse.

Dyetsani

Mwachiwonekere, zinthuzo ziyenera kudyetsedwa mu extruder kuti ziyambe kusakaniza.Mgolo wodyetsera ndi mbiya yotseguka yopangidwa kuti ikhale ndi potseguka pamwamba pa mbiya momwe zinthu zimadyetsedwa.Malo odziwika kwambiri a ng'oma ya chakudya ali pamalo 1, yomwe ndi mbiya yoyamba mu gawo la ndondomekoyi.Zinthu za granular ndi tinthu tating'onoting'ono tomwe timayenda momasuka timayezedwa pogwiritsa ntchito chodyetsa, chomwe chimawalola kuti agwere molunjika muchochocho kudzera mu mbiya ya chakudya ndikufikira pa screw.

Ufa wokhala ndi kachulukidwe kakang'ono nthawi zambiri umabweretsa zovuta chifukwa mpweya nthawi zambiri umanyamula ufa wogwa.Mpweya wothawa uwu umalepheretsa kutuluka kwa ufa wopepuka, kumachepetsa mphamvu ya ufa wodyetsa pamlingo wofunikira.

Njira imodzi yodyetsera ufa ndikuyika migolo iwiri yotseguka pamigolo iwiri yoyamba ya extruder.Muchikhazikitso ichi, ufa umadyetsedwa mu mbiya 2, kulola kuti mpweya wolowetsedwa utuluke ku mbiya 1. Kukonzekera kumeneku kumatchedwa chipangizo chakumbuyo chakumbuyo.Kumbuyo kwa mpweya kumapereka njira yoti mpweya utuluke kuchokera ku extruder popanda kutsekereza chute ya chakudya.Ndi kuchotsedwa kwa mpweya, ufa ukhoza kudyetsedwa bwino.

Polima ndi zowonjezera zikadyedwa mu extruder, zolimba izi zimatumizidwa ku malo osungunuka, komwe polima amasungunuka ndikusakanikirana ndi zowonjezera.Zowonjezera zimatha kudyetsedwa kumunsi kwa malo osungunuka pogwiritsa ntchito ma feeders am'mbali.

Kutopa

Gawo lotseguka la chubu lingagwiritsidwenso ntchito kutulutsa mpweya;Mpweya wosasunthika wopangidwa panthawi yosakaniza uyenera kutulutsidwa polima asanadutse kufa.

Malo odziwika bwino a doko la vacuum ndi kumapeto kwa extruder.Doko lotulutsa utsili nthawi zambiri limalumikizidwa ndi pampu ya vacuum kuwonetsetsa kuti zinthu zonse zosasunthika zomwe zimatengedwa mu polima zimasungunuka zimachotsedwa musanadutse mutu wa nkhungu.Nthunzi yotsalira kapena mpweya wosungunuka ukhoza kupangitsa kuti tinthu ting'onoting'ono ting'onoting'ono ting'onoting'ono, kuphatikizapo thovu ndi kuchepetsa kachulukidwe kazinthu, zomwe zingakhudze momwe ma CD amapangidwira.

Gawo la mbiya lotsekedwa

Chodziwika kwambiri chophatikizika cha mbiya ndi mbiya yotsekedwa.Gawo la mbiya limakulunga kwathunthu kusungunuka kwa polima kumbali zonse zinayi za extruder, ndikutsegula kumodzi kokha kwa mawonekedwe a 8 komwe kumalola kuti pakati pa wononga.

Polima ndi zina zilizonse zowonjezera zikadyetsedwa mu extruder, zinthuzo zidzadutsa gawo lotumizira, polima idzasungunuka, ndipo zowonjezera zonse ndi ma polima zidzasakanizidwa.Mgolo wotsekedwa umapereka kuwongolera kutentha kwa mbali zonse za extruder, pamene mbiya yotseguka imakhala ndi ma heaters ochepa ndi njira zoziziritsira.

Kusonkhanitsa mbiya ya extruder

Childs, extruder adzakhala anasonkhana ndi Mlengi, ndi masanjidwe mbiya kuti chikufanana zofunika ndondomeko kasinthidwe.M'machitidwe ambiri osakanikirana, extruder imakhala ndi mbiya yoyatsira yotseguka mu mbiya yodyera 1. Pambuyo pa gawoli lodyera, pali migolo ingapo yotsekedwa yomwe imagwiritsidwa ntchito kunyamula zolimba, kusungunula ma polima, ndi kusakaniza ma polima osungunuka ndi zowonjezera pamodzi.

Silinda yophatikizira imatha kukhala mu silinda 4 kapena 5 kuti ilole kudyetsa zowonjezera, kutsatiridwa ndi masilindala angapo otsekedwa kuti apitilize kusakaniza.Doko lotulutsa vacuum lili pafupi ndi mapeto a extruder, kutsatiridwa kwambiri ndi mbiya yomaliza yotsekedwa kutsogolo kwa mutu wakufa.Chitsanzo cha kusonkhanitsa mbiya chikuwoneka mu Chithunzi 3.

Kutalika kwa extruder nthawi zambiri kumawonetsedwa ngati chiŵerengero cha kutalika kwa wononga m'mimba mwake (L/D).Mwa njira iyi, kukulitsa gawo la ndondomekoyi kudzakhala kosavuta, monga extruder yaing'ono yokhala ndi L / D chiŵerengero cha 40: 1 ikhoza kukulitsidwa kukhala extruder ndi m'mimba mwake yaikulu ndi L / D kutalika kwa 40: 1.
