Q: How to identify the quality of the stacked screw sludge dewatering machine

Answer: Quality is the key criterion for people to evaluate products. How to test the screw dewatering machine, we need to start with the material, the material is 304 stainless steel, and the material less than 304 metal is not qualified material, one is easy to rust, and two plastic is easy to deform the weathering layer. The stacked screw sludge dewatering machine is a machine with a compact design, a small footprint, low energy consumption, low operating costs, environmental protection, energy saving, high-tech content, easy maintenance and replacement, small weight, and easy transportation. , Especially suitable for large, medium and small sewage treatment plants, urban sewage treatment plants, sewage treatment plants. The drying machine replaces the traditional filter cloth and suction filtration method with a unique filter body, which reduces operating costs and improves processing efficiency.


The old thinking thinks that the sludge dewatering machine with lower concentration must be dehydrated after extraction, which requires the basic construction of extraction and storage tanks to extract the sludge with lower concentration, which seems to be “basic knowledge”. However, the stacked screw sludge dewatering machine overthrew this “basic knowledge” and let everyone know that the original low-concentration sludge can be dehydrated immediately without extraction, so that the basic construction of extraction and storage tanks is omitted. The basic construction cost and farmland space of the sewage treatment station are greatly reduced.

The stacked screw sludge dewatering machine can immediately dedry the mud with a low concentration, which not only reduces the cost of basic construction, but more importantly, it can reduce the concentration of phosphorus while maintaining the immediate dehydration of the oxidation ditch. Released and odor caused.
Secondly, we also need to compare the production and processing technology, the production and processing of a sound ring, the price and quality of the production and processing of imported products and the production and processing of import and export machinery and equipment. Imported products are produced and processed with high flatness, and the machinery and equipment are durable. The flatness of domestic machinery and equipment produced and processed is low and easy to deform, and the machinery and equipment are not durable.

The screw-stacked waste water mud press is developing rapidly, and it is becoming more and more popular in the current environmental protection trend. Compared with the traditional plate and frame filter press, sludge filter press and decanter centrifuge, the stacked screw waste water mud press Machine contrast stands out. However, with the tight demand of screw stacking dehydrators, the quality of screw stacking waste water mud compactors is staggering and different.
How to check the quality of screw stacking waste water mud compactor, it is suggested to start from the following:

  1. Identify the establishment period, qualification certificate, sales performance, work experience, etc. of the screw stacking machine manufacturer
  2. Identify whether the material of the screw dehydrator is standard 304 stainless steel plate, whether there are components made of 201, composite resin and other materials
  3. Determine whether the model and specification of the screw dewatering machine meet the industry or industry standard specifications, and whether it can exceed the standard sludge production and specifications.
  4. Determine whether the production and processing of key components such as screw shafts and sound rings are professional and meticulous, which will immediately affect the service life of the screw dewatering machine and the actual effect of the sludge dewatering machine.
  5. In the sludge dewatering machine manufacturing industry, whether there are qualification certificates for independent innovation application and scientific research.
  6. Identify the operation status of the project and the water content of the sludge, and the degree of control and mastery of the wastewater in each manufacturing industry.
