The hollow paddle dryer is an indirect heating low-speed stirring dryer with two or four hollow rotating shafts inside the equipment. The fan-shaped wedge-shaped hollow blades are densely arranged in parallel on the hollow shaft. The structure is designed and clever. The shaft rotates relatively, and adopts the principle and structure of the same angular velocity and different linear velocity, which ingeniously realizes the self-cleaning effect of the sludge on the shaft, which can prevent the occurrence of the phenomenon of "holding the shaft" during the operation of the sludge. Sludge drying. During the drying process, the sludge is made to flow rapidly through the "colloid phase region". At the same time, the ingenious structure makes the sludge reach a bidirectional shearing state during the drying process.
Cov sludge qhuav yog tsis tu ncua thiab ntau npaum li cas pub rau hauv qhov chaw nres nkoj ntawm lub tshuab ziab khaub ncaws los ntawm cov ntsia hlau feeder. Tom qab cov sludge nkag mus rau hauv tib neeg lub cev, cov sludge yog tig thiab nplawm los ntawm kev sib hloov ntawm lub paddle, thiab cov cua sov interface yog hloov kho tas li mus cuag lub ntsiab lub cev thiab cov hniav, thiab tag nrho rhuab kom evaporate cov dej saum npoo muaj nyob rau hauv cov sludge. Nyob rau tib lub sijhawm, cov sludge raug xa mus rau qhov chaw nres nkoj tawm hauv ib qho kauv trajectory nrog kev sib hloov ntawm cov hniav ncej.
Thaum lub sij hawm conveying txheej txheem, cov sludge yog tas li stirred, kom cov dej seeping tawm ntawm cov sludge mus evaporate. Qhuav thiab tsim nyog cov khoom raug tso tawm ntawm qhov chaw nres nkoj tawm. Cov qauv ntawm lub plhaub tsho yog saws, yog li cov sludge yog sib npaug ntawm txhua qhov kev sib tshuam hauv lub tshuab, cov ncej tig, cov sludge yuav tsis yob hauv cov cuab yeej, thiab cov cua sov saum npoo yuav raug kho tsis tu ncua. Yog li ntawd, qhov ua tau zoo ntawm cov sludge hollow paddle tshuab ziab khaub ncaws tau zoo heev, uas tsis tsuas yog ua tiav lub hom phiaj ntawm sludge kom qhuav, tab sis kuj paub txog qhov qis - nqi ua haujlwm ntawm tag nrho cov cuab yeej.
