1. Kev ziab ntawm cov khoom siv kom qhuav
1. Qhov hnyav poob los ntawm cov khoom nyob rau hauv chav tsev lub sij hawm thiab chav tsev cheeb tsam yog hu ua drying rate.
2. Kev ua kom qhuav.
● Lub sijhawm pib: Lub sijhawm luv luv, txhawm rau kho cov khoom kom zoo ib yam li lub tshuab ziab khaub ncaws.
● Lub sijhawm ceev ceev: Qhov no yog thawj lub sijhawm nrog qhov ziab kom qhuav. Cov dej evaporated los ntawm qhov chaw ntawm cov khoom yog ntxiv rau hauv, yog li cov yeeb yaj kiab dej saum npoo tseem nyob ntawd thiab khaws cia ntawm qhov kub thiab txias.
● Theem 1 ntawm deceleration: Lub sijhawm no, cov dej evaporated tsis tuaj yeem rov qab ua tiav hauv, yog li cov yeeb yaj kiab dej saum npoo pib tawg, thiab qhov ziab qhuav pib qeeb. Cov khoom siv hu ua qhov tseem ceeb ntawm lub sijhawm no, thiab cov dej uas muaj nyob rau lub sijhawm no yog hu ua cov dej noo tseem ceeb.
● Theem 2 ntawm deceleration: theem no tsuas yog muaj rau cov ntaub ntawv ntom ntom, vim dej tsis yooj yim los; tab sis tsis yog rau cov khoom ntxeem tau. Hauv thawj theem, evaporation ntawm dej feem ntau yog nqa tawm ntawm qhov chaw. Nyob rau theem ob, cov yeeb yaj kiab dej ntawm qhov chaw tau ploj mus tag nrho, yog li cov dej ntws mus rau saum npoo ntawm cov dej vapor.
2. Cov yam ntxwv cuam tshuam rau qhov nrawm nrawm nrawm nrawm
● Huab cua kub: yog tias qhov kub thiab txias, qhov sib txawv thiab qhov evaporation ntawm hws yuav nce.
● Cov av noo ntawm huab cua: Thaum cov av noo qis dua, cov evaporation ntawm cov dej yuav loj dua.
● Airflow ceev: qhov nrawm dua, qhov zoo dua qhov hloov pauv huab cua thiab cua sov.
● Shrinkage thiab case hardening: Ob qho xwm txheej yuav cuam tshuam rau ziab.
3. Kev faib cov khoom siv kom qhuav
Cov dej noo ntau dhau yuav tsum tau muab tshem tawm kom ntau li ntau tau ua ntej cov khoom nkag mus rau hauv cov khoom siv.
● Cov tshuab ziab khaub ncaws rau cov khoom khib nyiab thiab pastes.
(1) Disc tshuab ziab khaub ncaws.
(2) Lub tshuab ziab khaub ncaws.
(3) Rotary Dryer.
(4) Ntsia Hlau Conveyor Dryers.
(5) Overhead tshuab ziab khaub ncaws.
(6) Lub tshuab ziab khaub ncaws.
(7) Flash evaporation tshuab ziab khaub ncaws.
(8) Lub tshuab ziab khaub ncaws.
● Cov tshuaj thiab slurry yog qhuav los ntawm thermal evaporation.
(1) Lub tshuab ziab khaub ncaws.
(2) Lub tshuab ziab khaub ncaws.
