Application:Sewage Treatment,Wastewater Treatment
The volute sludge dewatering machine for sewage treatment utilizes the principle of screw extrusion, the strong squeezing force generated by the change of screw diameter and pitch, and the small gap between the traveling ring and the fixed ring, to achieve the extrusion dewatering of sludge. A new type of solid-liquid separation equipment.
The main body of the volute sludge dewatering machine for sewage treatment is composed of multiple fixed rings and traveling rings, and the screw shaft penetrates the filter device formed therein. The front section is the concentration section, and the rear section is the dehydration section. The sludge concentration and squeezing dehydration work is completed in a tube, replacing the traditional filter cloth and centrifugal filtering method with a unique and delicate filter body mode.
The sludge is concentrated in the concentration section by gravity and then transported to the dehydration section.As the filter slit and pitch gradually become smaller during the process of progress, and the back pressure plate is blocked, it generates a great internal pressure and the volume continues to shrink To achieve the purpose of full dehydration.
1. The unique dehydration principle makes the equipment suitable for high and low concentration sludge, starting from 2000mg / L, creating a precedent for direct dehydration of low concentration sludge.
2. Innovative structural design makes the equipment suitable for various types of sludge with high and low viscosity, especially oily sludge, which can be called a weapon for dewatering oily sludge.
3. Continuous automatic operation: The volute sludge dewatering machine adopts automatic control from the extraction of sludge, injection of chemical liquid, and discharge of sludge cake. It does not require personnel to operate the equipment. There will be no blockage, deviation of the filter belt or other phenomena that affect the safety of the process. The daily maintenance is simple and convenient, and it can be operated continuously without people for 24 hours. For the first time, continuous and fully automatic operation of sludge dewatering was realized.
4. Saving operating costs: The integrated overall design, compact design, greatly saves operating costs. Low-speed spiral extrusion technology makes the power consumption greatly reduced; the equipment is not clogged, the flushing water is greatly reduced; 24 hours of automatic unmanned operation, the labor cost is greatly reduced. Therefore, this equipment has truly become a new type of energy-saving and environmentally friendly equipment that complies with national policies.
5. No secondary pollution: The rotation speed of the screw shaft is about 2 ~ 3 rpm, no vibration, and the noise is very small; its lamination has a self-cleaning function, no clogging problem, only a small amount of water is rinsed, no secondary water Pollution; coupled with sludge running in such a slow working state, the odor does not diffuse, so a very good operating environment is created!
6. The body is light and durable: the machine is designed to be very light due to the direct use of mechanical extrusion dehydration without the need for large bodies such as rollers; the body is almost entirely made of stainless steel, and the replacement parts are only the spiral shaft and the traveling ring, which has a long service life and long durability durable.
7. Saving project investment: The volute sludge dewatering machine itself has the function of sludge concentration, which can directly process the aerobic sludge in the aeration tank without the need for concentration and storage units, reducing the overall space and construction cost of the sewage treatment facility.
8. Improve the phosphorus removal function: The sludge is dehydrated under aerobic conditions, and the phosphorus release of the sludge in the conventional sludge concentration tank or storage tank under anoxic or anaerobic conditions will not occur, thereby improving the removal of the entire sewage treatment system Phosphorus function.
The volute sludge dewatering machine can be widely used in municipal sewage, food, beverage, slaughter and breeding, printing and dyeing, petrochemical, paper, leather, pharmaceutical and other industries for sludge dewatering.
