Stacked screw sludge dewatering machine

Stacked screw sludge dewatering machineIt is a mechanical equipment that utilizes the relative motion between a spiral shaft and multiple fixed/moving laminations (rings) to continuously concentrate and filter dewater sludge under the squeezing effect of multiple filter bodies. It is a low-speed, low-energy, continuous operation solid-liquid separation equipment.

Compared with traditional plate and frame filter presses and belt filter presses, its core feature is the dynamic and static ring (laminated) filtration structure, which is not easily clogged and suitable for treating sludge that is difficult to dewater, such as oily and viscous sludge.

Features and Advantages

Low speed energy-saving: Extremely low speed (2-3 revolutions per minute), minimal power consumption, and low operating costs.

◆ Not easy to clog, self-cleaning: The unique relative movement of the dynamic and static rings can automatically remove blockages between the stacked pieces, and has good adaptability to viscous and oily sludge.

◆ Continuous automatic operation: It can achieve 24-hour unmanned continuous operation without the need for frequent start and stop like panel and frame machines.

◆ Dehydration main body closure: friendly operating environment, minimal odor emission, and clean work site.

Small and compact, easy to install: small in size, light in weight, no need for large foundations, and even movable.

◆ Simple maintenance and long lifespan: The main components are made of stainless steel, with few moving parts. Daily maintenance only requires regular lubrication and cleaning, and there are basically no vulnerable parts (such as filter cloth).

Moderate solid content in the discharged sludge: Typically, sludge with a moisture content of over 99% can be dehydrated to a moisture content of 80% -85%, meeting general transportation and disposal requirements.

Application field

Municipal sewage treatment plant: suitable for dewatering excess sludge and digested sludge.

Industrial wastewater treatment station:

(1) Food processing (high in oil and organic matter).

(2) Slaughtering and breeding (high viscosity, high fat).

(3) Paper making, textile, printing and dyeing.

(4) Petrochemical industry (oily sludge, excellent effect).

(5) Electroplating and metal processing (after conditioning).

Dredging silt from rivers and lakes: dealing with large amounts and complex components of silt.

Stacked screw sludge dewatering machineIt is an ideal choice for sludge dewatering scenarios that are suitable for small and medium-sized, mainly organic matter, and have high requirements for the on-site environment. It has become one of the mainstream dehydration equipment in municipal and many industrial fields due to its core advantages of low energy consumption, easy maintenance, continuous operation, and good anti clogging performance.
