[0002] Microporous filter (also known as microfilter, ultrafine filter and dirt collector, etc.) is a device that uses porous solid adsorbent to remove particulate impurities in water so that the effluent water quality meets the prescribed water supply and discharge standards. It is usually composed of a filter element, which has the advantages of small size, high efficiency, strong corrosion resistance and low resistance, and can intercept particles larger than 0.1 to 1um.

[0003] After long-term use, a large amount of residue will accumulate on the filter element of the existing microporous filter to clog the mesh, so it needs to be cleaned. Traditional manual cleaning has many inconveniences. Therefore, patent CN211069220U discloses a microporous filter, including a shell assembly and a filter assembly. The shell assembly includes a cylinder, a cover, a support frame, an inlet pipe, a drain pipe, a sewage pipe and an overflow pipe. The top of the cylinder is provided with the cover, and the lower surface of the cylinder is fixed with the support frame.

[0029] The specific operation is as follows. By designing the cleaning mechanism 3 and the above-mentioned related structures, when working, sewage enters through the inlet on one side of the upper shell 11, and the water level is lower than the ring plate 18. Then the sewage is purified by the filter element main body 2 and discharged by the drain pipe 21, and a small amount of sewage can be discharged through the bottom conduit of the lower shell 12. When cleaning, the two sealing plates 16 are opened, and the soft brush strip 34 is placed, and the slideway of the soft brush strip 34 is passively inserted into the slider 33 until the slider 33 is in contact with the top surface of the slideway. At this time, the manual bolt 35 is inserted from the top of the soft brush strip 34 and inserted into the bolt hole of the slider 33 to be fixed, and the brush contacts the outer wall of the filter element main body 2. At this time, the cleaning motor 17 is started to drive the rotating cylinder 31 to rotate, and the rotating cylinder 31 drives the rotating plate 32 and then drives the soft brush strip 34 to clean the residue and dirt on the outer wall of the filter element main body 2. In this way, the residue on the outer wall of the filter element main body 2 can be effectively cleaned, and the problem of corrosion caused by long-term contact with sewage of the cleaning components can be avoided. After the cleaning is completed, the soft brush strip 34 is removed, which can also be convenient for maintenance and cleaning, and is worthy of promotion and use.

When entering water in daily use, water may splash into the rotating cylinder 31 and other components through the middle circular opening of the ring plate 18. Therefore, during installation, two arc-shaped baffles 4 can be placed in the middle circular opening of the ring plate 18 to form an annular plate, and the rubber ring 41 fits with the outer wall of the filter element main body 2, which then plays a good protective role. During cleaning, the arc-shaped baffles 4 are lifted and separated through the buckle 42, and then the two arc-shaped baffles 4 are lifted and placed in the arc-shaped groove 19. After cleaning, the soft-bristle brush strip 34 is removed, and then the arc-shaped baffle 4 is put back to its original place. It is very convenient. Note that the top cover on the top of the upper shell 11 is an existing design. After the upper shell 11 and the lower shell 12 are spliced, the arc-shaped baffle 4 is first inserted and then the top cover is installed, which does not affect the overall assembly process.
