High Oil Slurry Multi Disc Screw Press Sludge Dewatering Equipment For Printing And Dyeing

 

The main part of the dehydrator is a filter device that a screw runs through the stacked fixed

 

rings and moving ring.
 

The small gaps between fixed rings and moving ring can filter the sludge, and the

 

lumenbetween screw and rings is filled with polymer grains. The moving ring transfers the

 

sludge to the end of the machine with pressure and extrudes sludge cakes.
 

The running of the screw drives the moving ring to clean the gaps and avoid jam.

 

Flow Diagram:

1.The sludge in the sludge sump is carried to the measuring tank by sludge pump.And the

 

sludge inlet volume can be controlled by adjusting the liquid level tube.
 

2.Sludge and flocculant will form alum floc in the disposal tank after agitator mixing.
 

3.After gravity thickening in the thickening part, large amount of filtrate will discharge from the

 

gaps between rings.
 

4.The thickened sludge is carried forward by the screw and dehydrated sufficiently under the

 

pressure of the back pressure plate.
 

5.The dehydrated mud cake is discharged from the gaps between back pressure plates and

 

screw body. The treating capacity of sludge and water content's rate of mud cake can be

 

controlled by adjusting the running speed of screw and gaps between back pressure plates.

 

 

Advantage

 

1. Widely Use
(1). Can be widely used in municipal sewage, food, slaughtering breeding, printing and

 

dyeing, oil chemical industry, paper making, leather, pharmaceutical and other industries of

 

sludge dewatering;
 

(2). Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-

 

50000mg/L:
 

(3). Due to the innovation of the structure design, it is highly suitable to various high and low

 

concentration sludge, most especially for the oily ones.
 

2. Clog-free
 

Due to rotation of helical axis, the moving rings begin detaching from the fixed rings while

 

continuously starting the self-cleaning process. As a result, the ubiquitous clogging is avoided.

 

Therefore, it can handle oily sludge without any trouble while separating the water from the

 

sludge easily. In addition, there is no need to add large quantity of flushing water and there is

 

no odor and no secondary pollution during the dewatering process.
 

3. Fully Automatic Control
 

There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press.

 

Combining with the auto control system, the machine runs very safely and simply and can be

 

programmed according to the requirement of the users. It can operate automatically for 24

 

hours, unmanned.
 

4. Save Running Cost
 

Volute sludge dewatering works by the machine’s internal pressure and needs no large scale

 

integrations like rollers. It saves energy and water and has very minimal noise because of low

 

running speed (2-4 r/min). The average unit power consumption is only 0.1-0.01kwh/kg-DS

 

(1/8 of Belt Press and 1/20 of Centrifuge), and can greatly reduce the running cost of

 

 

wastewater treatment system.
