Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, and more specifically, to a gravity-type valveless sewage filter. Background Art

[0002] Steel gravity valveless filters are manufactured by the manufacturer and anti-corrosion is done with non-toxic paint. They are prefabricated and welded into several parts by the manufacturer in the factory. After being transported to the site, the manufacturer's staff continue to weld them together. After anti-corrosion again, they are delivered to the construction unit for taking over. After filling the filter material, they can be put into trial and operation, which greatly shortens the construction period. Factory production is not affected by the construction season.

[0003] The existing patent number CN 216295297 U discloses an integrated gravity valveless filter, which can unify all filter tanks for filtering operations while using one water tank and one sewage tank. Therefore, only one pressurizing device is needed to pressurize the water tank and input sewage into the filter tank, which greatly reduces the cost, and the synchronous filtration effect is good and the efficiency is high. However, when the space in the filter layer is small, the backwashing space is small and the flushing effect is not good. When the filter layer space is large, the filter layer density is small, which affects the filtering effect.

[0004] In view of this, research and improvement are conducted on the existing problems, and a gravity-type valveless sewage filter is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0008] As a further optimization of the technical solution, the utility model provides a gravity-type valveless sewage filter in which the filter partition is plugged and connected to the inner wall of the water filter tank as a sliding device.
