Screw type sludge dewatering machine
The stacked screw type sludge dewatering machine follows the principles of force and water in the same direction, thin layer dewatering, appropriate pressure and extension of dewatering path, solves the technical problems of previous generations of sludge dewatering equipment, such as easy blockage, unable to deal with low concentration sludge and oily sludge, high energy consumption and complex operation, and achieves the goal of high efficiency and energy saving. Under the condition of full-automatic operation, the dehydrator can realize high-efficiency flocculation, continuously complete sludge thickening and pressing dehydration, and finally return or discharge the collected filtrate. It is widely used in municipal sewage treatment engineering and water treatment system of aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather and other industries.
Working Principle
During the operation of the equipment, the sludge is pushed to the discharge port by the spiral blade after entering the filter cartridge from the feed port. As the pitch of the spiral blade is gradually reduced, the pressure on the sludge increases and begins to dehydrate under the pressure. The water flows out from the gap between the fixed ring and the movable ring. At the same time, the equipment relies on the self-cleaning function between the fixed ring and the movable ring to clean the sludge The filter clearance is swept to prevent blockage, and the mud cake is discharged from the discharge port under the propulsion of the screw shaft after dehydration.
The main body of the screw type sludge dewatering machine is a filtering device formed by a fixed ring and a movable ring which are overlapped with each other and through which a spiral shaft runs. The former part is concentrated part and the latter part is dehydrated part.
The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration section to the dehydration section.
The rotation of the screw shaft drives the sludge to be transported from the thickening section to the dewatering section, at the same time, it also drives the floating ring to clean the filter seam to prevent blockage.
Main Feature
1.With 304stainless steel cover,which is easy to take off and observe.
2.Screw and screen adopt high quality 304SUS,Which is preservative,can use long time.
3.Easy operate,small dimension,low noise,work stable.
4.Low moisture content after press,you can't press out water by hand.After press the moisture content is around 60%.
5.Screw is full welding,which is more durable.
Application
The stacked screw type sludge dewatering machine follows the principles of force and water in the same direction, thin layer dewatering, appropriate pressure and extension of dewatering path, solves the technical problems of previous generations of sludge dewatering equipment, such as easy blockage, unable to deal with low concentration sludge and oily sludge, high energy consumption and complex operation, and achieves the goal of high efficiency and energy saving. Under the condition of full-automatic operation, the dehydrator can realize high-efficiency flocculation, continuously complete sludge thickening and pressing dehydration, and finally return or discharge the collected filtrate. It is widely used in municipal sewage treatment engineering and water treatment system of aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather and other industries. At present, there are 16 types of easy maintenance stacked screw sludge dehydrators manufactured by our company to adapt to different sludge treatment capacity and different needs of customers.

A picture for you to understand the screw folding machine
Reasons for choosing us
1. Exquisite appearance and fine workmanship
304 drawing stainless steel body, base after surface sandblasting, fine workmanship, will be beautiful and technology integration
2. Processing of moving and fixed rings
After six rigorous processes: laser cutting, grinding, inner ring chamfering, machine leveling, stress relief, comprehensive detection
3. Spiral shaft strengthening process
Compared with the traditional welding spiral blade, the continuous cold rolling spiral blade has smooth surface, regular shape and high precision, which is conducive to material transportation, reducing material damage and improving transportation efficiency; the supersonic tungsten carbide coating is adopted, with spraying thickness of 0.3mm and hardness of 1200hv, which ensures the wear resistance and service life of the spiral shaft to the maximum extent.
4. Electric control cabinet and electronic components
It adopts Omron,other first-line brand electronic components, with reasonable wiring, neat wiring, low failure rate and guaranteed safety
5. Drive motor
It adopts the first-line brands such as rizing and Guomao, which makes the operation more stable and reliable
6. Strict selection of accessories and professional decision of details
