Introduction to screw stacker screw sludge dehydrator
The screw stacker sludge dehydrator is a screw press dehydrator, which can reduce the sedimentation tank and sludge thickener, and save the construction cost of the sewage station. The stacked screw sludge dehydrator ingeniously uses the multiple ring automatic cleaning filtration technology to replace the traditional screen filtration. The self-cleaning filtration technology ensures the continuous and stable sludge and water separation effect of the dehydrator. It is a new type of solid-liquid separation equipment that realizes the squeezing dehydration of sludge through the strong squeezing pressure generated by the change of screw diameter and screw pitch, as well as the small gap between the moving ring and the fixed ring.
1. Continuous automatic operation
The stacker sludge dehydrator is automatically controlled from sludge extraction, pharmaceutical injection, and sludge cake discharge. Through the electric control cabinet, it is linked with the dosing machine, sludge pump, and dosing pump. No personnel are required to operate the equipment. The operation will not occur blocking, track deviation, or other phenomena that affect the process safety. The daily maintenance is simple, and it can be continuously unmanned for 24 hours. For the first time, continuous and automatic operation of sludge dewatering has been realized.
2. Saving operation costs
Integrated overall design, compact design, greatly saving operating costs. Low-speed screw extrusion technology can greatly reduce the power consumption of the equipment without blocking, greatly reduce the water for washing, fully automatic unmanned operation for 24 hours, and greatly reduce the labor cost. Therefore, this equipment also really becomes a new type of energy-saving and environmental protection equipment in line with national policies.
3. No secondary pollution
The rotating speed of the screw shaft is about 2-3 rpm, without vibration, and the noise is very small. Its lamination has the cleaning function, and will not cause blocking problems. Only a small amount of water is needed to wash, and there is no secondary water pollution. In addition, the sludge is carried out in such a slow working state, and the odor does not spread, creating a very good operating environment at one time.
4. The body is light and durable
Because of the direct use of mechanical extrusion dehydration, without the need for large bodies such as rollers, the machine is designed to be quite lightweight; The machine body is almost made of stainless steel, and the replacement parts are only spiral shaft and traveling ring, with long service life and durability.
5. Saving project investment
The sludge dewatering machine itself has the sludge thickening function. It can directly treat the aerobic sludge in the aeration tank without concentration and storage unit, reducing the overall floor space and construction cost of the sewage treatment facility.
6. Improve phosphorus removal function
When sludge is dehydrated under aerobic conditions, it will not release sludge phosphorus in traditional sludge thickener or storage tank under anoxic or anaerobic conditions, thus improving the phosphorus removal function of the whole sewage treatment system.
