Ihame rya twin screw barrel guhuza

Gufungura imashini ya barriel igice

Ibishushanyo bimwe na bimwe bitanga iboneza ryihariye rya twin screw extruders. Mugihe duhujije buri barrale hamwe nuburyo bukwiye bwa screw, tuzakora ubushakashatsi rusange kandi bwimbitse kuri buri bwoko bwikibari kubikorwa byibice byihariye kuri kiriya gice cya extruder.

Buri gice cya barrale gifite umuyoboro umeze 8 unyuramo umugozi wa screw. Barrale ifunguye ifite imiyoboro yo hanze yemerera kugaburira cyangwa gusohora ibintu bihindagurika. Ibishushanyo bifunguye birashobora gukoreshwa mugaburira no kunaniza, kandi birashobora gushirwa ahantu hose murwego rwose.

Kugaburira

Biragaragara, ibikoresho bigomba kugaburirwa muri extruder kugirango utangire kuvanga. Igaburo ryo kugaburira ni ingunguru ifunguye yagenewe kugira gufungura hejuru ya barrile inyuzwamo ibikoresho. Umwanya usanzwe kubiryo byingoma ni kumwanya wa 1, nicyo kibanza cya mbere mugice cyibikorwa. Ibikoresho bya granulaire hamwe nuduce duto twisanzuye bipimwa hifashishijwe ibiryo, bikabemerera kugwa muri extruder binyuze muri barrique yo kugaburira no kugera kuri screw.

Ifu ifite ubucucike buke akenshi itera ibibazo kuko umwuka akenshi utwara ifu igwa. Umuyaga uhunga uhagarika urujya n'uruza rw'ifu, bigabanya ubushobozi bw'ifu yo kugaburira ku kigero gikenewe.

Uburyo bumwe bwo kugaburira ifu nugushiraho ibibari bibiri bifunguye kuri barrele ebyiri zambere za extruder. Muriyi miterere, ifu igaburirwa muri barrale 2, ituma umwuka winjiye usohoka muri barrile 1.Iyi miterere yitwa igikoresho cyinyuma. Umuyaga winyuma utanga umuyoboro wumwuka usohoka muri extruder utabangamiye ibiryo byokurya. Hamwe no gukuraho umwuka, ifu irashobora kugaburirwa neza.

Iyo polymer hamwe ninyongeramusaruro bimaze kugaburirwa muri extruder, ibyo bikoresho bijyanwa mukarere gashonga, aho polymer yashonga ikavangwa ninyongeramusaruro. Inyongeramusaruro zirashobora kandi kugaburirwa epfo na ruguru yo gushonga ukoresheje ibiryo byo kuruhande.

Umunaniro

Igice gifunguye gishobora kandi gukoreshwa mu gusohora; Imyuka ihindagurika ikorwa mugihe cyo kuvanga igomba gusohoka mbere yuko polymer inyura mu rupfu.

Umwanya ugaragara cyane wicyambu cya vacuum ugana kumpera ya extruder. Iki cyambu gisohora ubusanzwe gihujwe na pompe ya vacuum kugirango harebwe ko ibintu byose bihindagurika bitwarwa na polymer byashizwemo mbere yo kunyura mumutwe. Imyuka isigaye cyangwa gaze mu gushonga birashobora gutuma habaho ubuziranenge buke, harimo kubira ifuro no kugabanya ubwinshi bwo gupakira, bishobora kugira ingaruka ku gupakira ibintu.

Igice gifunze

Igishushanyo gikunze kwambukiranya ibice bya barriel birumvikana ko gifunze. Igice cya barrale gifunga burundu polymer yashonga kumpande enye zose za extruder, hamwe nugukingura kamwe kamwe gusa 8 gatuma hagati ya screw inyuramo.

Iyo polymer nibindi byongeweho bimaze kugaburirwa byuzuye muri extruder, ibikoresho bizanyura mugice cyo gutanga, polymer izashonga, nibindi byose hamwe na polymers bizavangwa. Ikigega gifunze gitanga ubushyuhe kumpande zose za extruder, mugihe ingunguru ifunguye ifite ubushyuhe buke hamwe numuyoboro ukonje.

Guteranya ingunguru ya extruder

Mubisanzwe, extruder izateranyirizwa hamwe nuwabikoze, hamwe nimiterere ya barrale ihuye nibikorwa bikenewe. Muri sisitemu nyinshi zo kuvanga, extruder ifite ingunguru yo kugaburira ifunguye muri barri yo kugaburira 1. Nyuma yiki gice cyo kugaburira, hari ibibari byinshi bifunze bikoreshwa mu gutwara ibintu bikomeye, gushonga polymers, no kuvanga polymers zashongeshejwe hamwe ninyongeramusaruro hamwe.

Ihuriro rya silinderi irashobora kuba muri silindiri 4 cyangwa 5 kugirango yemererwe kugaburira kuruhande rwinyongeramusaruro, hagakurikiraho silinderi nyinshi zifunze kugirango zikomeze kuvanga. Icyambu cya vacuum giherereye hafi yimpera ya extruder, gikurikirwa hafi na barri ya nyuma ifunze imbere yumutwe wapfuye. Urugero rwo guteranya ingunguru urashobora kuboneka mu gishushanyo cya 3.

Uburebure bwa extruder mubusanzwe bugaragazwa nkikigereranyo cyuburebure na diameter ya screw (L / D). Muri ubu buryo, kwagura igice cyibikorwa bizoroha, nkumusemburo muto ufite igipimo cya L / D cya 40: 1 urashobora kwagurwa muri extruder ifite diameter nini na L / D uburebure bwa 40: 1.
