Product Description

Volute Sludge Dewatering Machine Screw Press

Dewatering Sludge Machine Screw Press is a kind of economic and environmental friendly sludge dewatering equipment. It is a new type of sludge extrusion dewatering equipment by using the principle of screw extrusion, through the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation. Gdewatering screw press is composed of fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering device, and liquid collecting tank. GN dewatering screw press is with automatic control technology, which can realize the flocculation fully automatic operation, and continuously complete the sludge thickening and squeezing, finally return or discharge the collected filtrate liquid.

Product features:

1. Wide range of applications
It is widely used in sludge dewatering in municipal sewage, food, beverage, slaughtering, printing and dyeing, petrochemical, paper, leather, pharmaceutical and other industries.
The unique dehydration principle makes the equipment suitable for high and low concentration sludge. Starting from 2000m/L, it has created a precedent for direct dewatering of low concentration sludge. The innovative structural design makes the equipment suitable for all types of sludge with high and low viscosity, especially oily sludge. It is a tool for dewatering oily sludge.

2, equipment is not easy to block
The unique dynamic and static ring filter joint structure makes the equipment not easy to block, and does not need to be cleaned to prevent the filter joints from being clogged, completely reducing the flushing water consumption, reducing the internal circulation burden, and solving the troubles caused by the traditional dewatering equipment blockage.

3, continuous automatic operation
The snail sludge dewatering machine pumps the sludge, adds the liquid medicine, and discharges the mud cakes. It is automatically controlled by the electric control cabinet, the dosing device, the mud pump, the dosing pump, etc., without the need for personnel to operate the equipment. The operation will not cause blockage, filter belt deviation or other phenomena that affect the safety of the process. The daily maintenance and maintenance is simple and can be run continuously for 24 hours. For the first time, the continuous automatic operation of sludge dewatering was realized.

4, save operating costs
Integrated compact design saves operating costs; Low-speed spiral extrusion saves electricity costs; Equipment is not blocked, and water consumption is greatly saved; Automatic unmanned operation saves labor costs.

5, no secondary pollution
The rotation speed of the screw shaft is about 2-3 rpm, the vibration is small, and the noise is very small. The stacking screw has self-cleaning function, no clogging problem, only a small amount of water washing, no secondary pollution; The mud runs under such a slow working condition, and the odor does not spread, thus creating a very comfortable operating environment.

6. The body is light and durable
Due to the direct use of mechanical extrusion dewatering, there is no need for a large body such as a drum, so the machine is designed to be quite lightweight; the body is almost entirely made of stainless steel, and the replacement parts are only the screw shaft and the swimming ring, which has a long service life and durability.

7, Saving engineering investment
The snail sludge dewatering machine itself has a sludge concentration function, which can directly treat the aerobic sludge in the aeration tank, does not require a concentration and storage unit, and reduces the overall land occupation and construction cost of the sewage treatment facility.

8, Enhance the function of phosphorus removal
The sludge is dehydrated under aerobic conditions, and the release of sludge phosphorus under the anoxic or anaerobic conditions in the conventional sludge concentration tank or storage tank does not occur, thereby improving the phosphorus removal function of the entire sludge treatment system.

3. Work principle:
The main body of the TLDL series snail sludge dewatering machine is composed of multiple fixing rings and swimming rings, and the screw shaft penetrates through the filtering device formed therein. The front section is the enrichment section and the rear section is the dewatering section. The sludge concentration and press dewatering work is completed in one cylinder, replacing the traditional filter cloth and centrifugal filtration mode with a unique and delicate filter mode.
After being concentrated by gravity in the concentration section, the sludge is transported to the dewatering section. During the advancement process, as the filter joint and the pitch gradually become smaller, and the back pressure plate blocks, the pressure is greatly increased, and the volume is continuously reduced. Fully dehydrated.
