Product Description

Product description

The company produces and manufactures the s crew type sludge dehydrator, at present, has formed a variety of specifications and models series to meet dif fferent sludge treatment capacity and different needs of customers.

The double screw sludge dewatering machine integrates the automatic control cabinet and sludge concentration and dehydration body with liquid tar nk. It can realize high-efficiency flocculation under the condition of full automatic operation, and contin huously complete sludge concentration and pressing dehydration, and finally return or discharge the collected filtrate.

 Features

 The process is simple, sludge dewatering is efficient and energy-saving, and the system investment is small.
 The system can be programmed to make the operation convenient and accurate. 
 Unique flocculant makes sludge dewatering easier. 
 The dispensing is uniform and accurate, and the operation cost is saved.
 
Compared with the traditional sludge dewateri ing machine, the dewatering body, flocculation mixing tank and electronic control cabinet of the lam inated snail sludge dewatering machine adopt the three-dimensional integrated design, which is conver nient to install, occupies a small area, is compatible with the ancillary equipment, and is easy to replace the original equipment.

The main body of the stacked screw sludge dewatering machine is composed of multiple fixed rings and swimming rings, and the screw shaft runs through it to form a filtering device.

The front section is the concentration section, and the back section is the dehydration section, which completes the sludge concentration and dehydration in one cylinder, and replaces the traditional filter cloth and centrifugal filtration methods with a unique and subtle filter pattern.

Remark: The cleaning water quantity and maintenance frequency are the reference values,and the specific data are subjict to the on-site use.

When the equipment is running, the sludge is pushed from the inlet to the filt barrel by the spiral spindle and moves to the discharge outlet. As the pitc h between the spiral spindles decreases gradually, the pressure on the sludge increases continuously, and under the action of pressure difference, the sludge begins to dehydrate, and the filter gap between the water fixing plate and the movable plate flows out. When the equipment relies on the self-cleaning function between the fixed plate and the movement, the clearance of the filter can be cleaned to prevent clogging, and the mud cake is discharged from the discharge outlet under the propelling action of the screw shaft after full dehydration.
