Muindasitiri yesimbi inokosha, nhanho imwe neimwe kubva pakuchenesa kusvika pakugadzirisa ine zvinodiwa zvakanyanya zvekushanda kwemidziyo, kururama, uye kuvimbika. Mumakore achangopfuura,magranulator evacuumDzakabuda senyeredzi iri kukura uye zvishoma nezvishoma dzava michina inodiwa muindasitiri iyi. Kune zvikonzero zvakawanda zvakadzama zveizvi, zvinosanganisira mativi akasiyana-siyana akadai sehunhu hwesimbi dzinokosha, zvinodiwa pakugadzira, uye mashandiro akanaka emidziyo yacho pachayo.

1. Kugadzirisa hunhu hwesimbi inokosha kuti ienderane nenzvimbo inotonhorera

Simbi dzinokosha dzakadai segoridhe, sirivha, platinum, nezvimwewo dzine kukosha kwakanyanya kwehupfumi uye hunhu hwemakemikari hwakagadzikana. Zvisinei, kuchine njodzi yekuoxidation nekusvibiswa munzvimbo dzakajairika dzakadai sekupisa kwakanyanya uye mamiriro emhepo. Chigadziko chevacuum chinogona kugadzira nzvimbo inenge isina vacuum, zvichibvisa okisijeni nemamwe magasi asina kuchena. Tichitora goridhe semuenzaniso, mukuita kwegranulation yakajairika, kupisa kwakanyanya kuchaita kuti pamusoro pezvidimbu zvegoridhe zvibatane neokisijeni, zvichiita kuti pave nechikamu che oxide chakatetepa zvikuru.

Kunyangwe izvi zvingaita sezvisina simba guru pakuchena kwegoridhe, mukugadzirwa kukuru uye minda yakadai semagetsi nezvishongo zvinoda kuchena kwakanyanya, zvikanganiso zvemhando yepamusoro zvinokonzerwa nekusvibiswa uku hazvigamuchirwi. Nzvimbo yekubuda mumhepo mukati memuchina wekubvisa simbi inoderedza huwandu hweokisijeni kusvika padanho rakaderera, zvichidzivirira zvakanyanya kusvibiswa kwesimbi dzinokosha panguva yekuumbwa kwesimbi, zvichiita kuti chigadzirwa chive chakachena zvakanyanya, uye zvichisangana nezvinodiwa zveindasitiri zvemhando yepamusoro yezvigadzirwa zvesimbi dzinokosha.

2. Kudzora kwakarurama kwemaitiro egranulation

Indasitiri yesimbi inokosha ine zvinodiwa zvakasimba uye zvakananga zvehukuru hwezvimedu, chimiro, uye huwandu hwezvigadzirwa. Chigadziko chevacuum, nerubatsiro rwehurongwa hwekudzora otomatiki yepamusoro, chinogona kudzora maparamita akasiyana-siyana nemazvo panguva yekugadzika kwegranulation. Nekudzora zvinhu zvakakosha zvakaita sekuyerera kwezvinhu, tembiricha, uye kumanikidzwa, kutonga kwakanyatsojeka kwehukuru hwezvimedu kunogona kuwanikwa. Mukugadzirwa kwezvimedu zvesimbi inokosha yemagetsi, zvinodikanwa kuti kugoverwa kwehukuru hwezvimedu kuve mukati mechikamu chakamanikana kwazvo kuti ive nechokwadi chekuti paste yakafanana uye yakagadzikana panguva yekudhinda, sintering, uye mamwe maitiro.

 Chigadziko chevacuum chinogona kugadzira zvidimbu zvine kutsauka kudiki kwehukuru hwezvidimbu kuburikidza nemagadzirirwo chaiwo eparameter uye kushanda kwakasimba, zvichizadzisa zvinodiwa nemazvo zveindasitiri yemagetsi yezvinhu zvinokosha zvesimbi. Panguva imwe chete, nekugadzirisa granulation mold uye process parameters, chimiro chezvidimbu chinogona kuchinjwa nyore nyore, kubva padenderedzwa kuenda ku columnar, uye mamwe maumbirwo, kuti zvienderane nezvinodiwa zvemashandisirwo akasiyana ehunhu hwezvinhu zvinokosha zvesimbi.

3. Kuratidza zvakanakira kushanda zvakanaka uye kuchengetedza simba

Kudzora mutengo kwakakosha mukugadzirwa kwesimbi dzinokosha. Dhizaini yemuchina wekugadzira simbi unoratidza kunyatsoshandisa simba zvakanaka. Nzvimbo yekushanda simbi inoderedza kufashaira kwechinhu ichi, zvichiita kuti tembiricha yekupisa iderere zvakanyanya pakuita simbi, nokudaro zvichideredza kushandiswa kwesimba. Zvichienzaniswa nemidziyo yechinyakare yekugadzira simbi, muchina wekugadzira simbi unokwanisa kuderedza kushandiswa kwesimba ne30% kusvika 50% pakugadzira simbi dzinokosha dzemhando imwe chete uye huwandu hwakaenzana.

Mukugadzirwa kukuru, kuchengetedza simba kwenguva refu kwakaunganidzwa kwakanyanya. Pamusoro pezvo, nzira yekugadzirwa inoenderera mberi ye granulator ye vacuum yakavandudza kushanda zvakanaka kwekugadzira. Midziyo iyi inogona kushanda nguva dzose munzvimbo yakagadzikana ye vacuum, ichiramba ichishandura zvinhu zvakakosha zvesimbi kuita zvigadzirwa zvemhando yepamusoro, ichideredza nguva yekushanda uye nguva yekugadzirisa mukugadzirwa, ichivandudza kubuda kwechinhu panguva imwe neimwe, uye ichideredza mutengo wekugadzira chigadzirwa chimwe nechimwe.

4. Kushanda zvakanaka kwezvakatipoteredza uye kuchengetedzeka

Nyaya dzekuchengetedzwa kwezvakatipoteredza nekuchengetedzwa hadzifanirwe kufuratirwa mukugadzirwa kwesimbi dzinokosha. Nzvimbo yakavharirwa yemuchina wekugadzira simbi inodzivirira guruva resimbi dzinokosha kuti risapfuure. Munzira dzechinyakare dzekugadzira simbi, kuburitsa guruva hakungokonzere chete kutambisa simbi dzinokosha, asiwo kunokanganisa nharaunda nehutano hwevashandi. Muchina wekugadzira simbi unodzivirira simbi yese muchina wekugadzira simbi, zvichibvisa mukana wekubuda kweguruva uye kuita kuti pave nekugadzirwa kwakachena.

Panguva imwe chete, nekuda kwekudzikira kwenjodzi dzinogona kukonzerwa nekupisa kwakanyanya, oxidation nezvimwe zvinokonzerwa nemakemikari, kuchengetedzeka kwevacuum granulator panguva yekushanda kunovandudzwa zvikuru. Paunenge uchibata nemamwe masotopu esimbi anokosha ane radioactive kana chepfu, nzvimbo yakavharwa yevacuum granulator inogona kuve nechokwadi chekuti vanoishandisa nenzvimbo yakapoteredza vakachengeteka, kudzivirira kubuda nekupararira kwezvinhu zvine radioactive kana chepfu.

5. Gadzirira zvinodiwa zvakasiyana-siyana zvekugadzira

Indasitiri yesimbi inokosha ine mashandisirwo akasiyana-siyana ezvigadzirwa, kubva kuzvishongo zvepamusoro kusvika kuzvinhu zvemagetsi zvepamusoro, kubva kumidziyo yekurapa chaiyo kusvika kuzvinhu zvakakosha muindasitiri yendege. Minda yakasiyana ine zvinodiwa zvakasiyana-siyana zvekushanda uye marongero ezvikamu zvesimbi zvinokosha. Chigadziko chesimbi chinoputika, chine kugona kwacho kwekugadzirisa maitiro, chinogona kukurumidza kuchinjika kune zvinodiwa izvi zvakasiyana-siyana zvekugadzira. Nekuchinja fomura yezvinhu, kugadzirisa maparamita emaitiro, uye kutsiva mamold akasiyana egranulation, magranulator esimbi anogona kugadzira zvigadzirwa zvezvikamu zvesimbi zvinokosha zvakakodzera mamiriro akasiyana ekushandiswa.

Muindasitiri yezvishongo, zvinodikanwa kugadzira zvidimbu zvesimbi zvinokosha zvakatenderera zvine pamusoro wakatsetseka uye ruvara rwakafanana rwekuisa mukati; Mubasa rekurongedza zvemagetsi, zvidimbu zvesimbi zvinokosha zvine saizi chaiyo uye kufamba zvakanaka zvinodiwa kuti zvive nechokwadi chekuti welding yakanaka. Chigadziko chevacuum chinogona kusangana nezvinodiwa izvi zvakasiyana, zvichipa rutsigiro rwakasimba rwehunyanzvi mukusimudzira kwakasiyana-siyana kweindasitiri yesimbi inokosha.

Muchidimbu,magranulator evacuumZvave zvishandiso zvinofarirwa zvisingapokanwe muindasitiri yesimbi inokosha nekuda kwekugadzirisa kwayo zvakakwana hunhu hwesimbi inokosha, kugona kwayo kudzora granulation, mabhenefiti ekushanda anoshanda zvakanaka uye anochengetedza simba, kushanda zvakanaka kwezvakatipoteredza uye kuchengetedzeka, uye kugona kuchinjika zvakanyanya kuzvinodiwa zvakasiyana-siyana zvekugadzira. Nekufambira mberi kwetekinoroji uye kusimudzira kudiwa kweindasitiri, mikana yekushandisa granulators dzevacuum muindasitiri yesimbi inokosha ichave yakakura, ichiita basa rakakosha mukusimudzira kukura kwemhando yepamusoro kweindasitiri yesimbi inokosha.
