The hollow shaft of the paddle dryer is densely arranged with wedge-shaped hollow paddles, and the heat medium flows through the paddles through the hollow shaft. The heat transfer area per unit of effective volume is large, and the temperature range of the heat medium is -40 degree -320 degree . It can be steam or liquid: such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to carry heat away. Heat is used to heat materials. Heat loss simply dissipates heat to the environment through the body's thermal insulation.
Lub tshav kub hloov chaw ntawm lub npoo - cov hniav zoo li tus kheej - ntxuav. Cov kev sib txheeb ntawm cov khoom siv thiab cov npoo npoo tsim cov nyhuv txhuam uas ntxuav tawm cov khoom siv los ntawm cov npoo npoo thiab tuav kom huv si hloov chaw thaum lub sijhawm ua haujlwm. Lub plhaub ntawm lub tshuab ziab khaub ncaws yog W- zoo li tus, thiab feem ntau muaj ob mus rau plaub lub hollow stirring shafts hauv lub plhaub. Lub plhaub yog muab nrog lub sealing kawg npog thiab lub hau npog sab sauv txhawm rau tiv thaiv cov khoom tawm ntawm cov plua plav thiab sau cov khoom hnyav vapor. Lub baffle yog teem rau ntawm qhov chaw nres nkoj tawm los xyuas kom meej qhov siab ntawm cov khoom theem, kom lub tshav kub hloov chaw yog them los ntawm cov khoom, thiab nws cov hauj lwm yog tag nrho exerted. Lub tshav kub hloov mus nruab nrab ntws los ntawm lub casing thiab hollow sib xyaw ncej los ntawm kev sib koom ua ke. Nyob ntawm seb hom cua sov nruab nrab, qhov hollow sib xyaw ncej muaj cov qauv sab hauv sib txawv kom ua tiav cov kev hloov hluav taws xob.
Muaj qee cov kauj ruam yooj yim uas tus neeg teb xov tooj yuav tsum ua raws li txhawm rau ua kom lub tog raj kheej ziab kom zoo. Nws yog tsim nyog sau cia tias:
Kev faib dej tsis sib xws tuaj yeem ua rau undercoating. Lub milling cutter yuav tsum xyuas tias lub scraper raug kho kom raug lossis hnav. Kev tshuaj xyuas ib ntus yuav tsum tau txiav txim siab yog tias tag nrho cov saum npoo yog coated, txwv tsis pub tus scraper yuav hnav tawm ntawm qhov tsis muaj coated.
Kev hnav tsis sib xws ntawm cov hniav qhia tias muaj teeb meem tshwm sim lossis tsis tsim nyog hnav ntawm lub txheej. Qhov profile ntawm lub scraper yuav tsum tau ua raws li qab lub tshuab ziab khaub ncaws kom hnav txawm tias.
Nto ntug hnav tsis cuam tshuam ncaj qha rau kev tsim khoom, tab sis tuaj yeem ua rau cov khoom ntim tsis tsim nyog. Kev sib tsoo tom ntej yuav tsum tau ua los ntawm sab hauv ntawm lub tshuab ziab khaub ncaws kom tau txais qhov tseeb yas profile.
