Abstract

The invention relates to a variable-hole filtering pool, which comprises a filtering pool body and is characterized in that an air inlet device and a water collection device are sequentially arranged in the filtering pool body from top to bottom. The variable-hole filtering pool mainly adopts coarse filtering materials, and the filtering is carried out through the whole filtering layer, so the surface filtering of the filtering layer formed by an ordinary filtering pool is avoided, the filtering layer resistance is reduced, previous penetration of suspension material particles is also avoided, and the filtering speed is also accelerated. Through the addition of fine filtering materials and the uniform mixing in the filtering layer, the local porosity of the coarse filtering materials is greatly reduced, the flocculation effect of fine particles in sewage is improved, tiny particles can be more favorably removed, and the pollutant interception capability of the filtering pool is also greatly improved. The total equipment investment cost is reduced, the occupied area is small, the filtering effect is better, the filtering time is shortened, and the operation work procedure is reduced. After the variable-hole filtering pool is matched with a pneumatic valve and a programmable logic controller (PLC), the fully automatic control can be realized.

Description

technical field [0001] The invention relates to a filter tank device, in particular to a variable porosity filter tank. Background technique [0002] At present, some filters are used to remove suspended solids in water to obtain water with lower turbidity; some are used to remove water from sludge to obtain sludge with lower water content. [0003] The existing filter only forms the surface filtration of the filter layer, and the resistance of the filter layer is relatively large, resulting in premature penetration of suspended particles, and the filtration rate is slow; the local porosity of the filter material is large, and the flocculation of fine particles in the sewage Not obvious. Contents of the invention [0004] The object of the present invention is to provide a variable porosity filter which overcomes the disadvantages mentioned above. [0005] Technical scheme of the present invention is: [0006] A variable porosity filter, comprising a filter body, ...
