The recoil-type industrial water filter is installed on water supply pipes in various industries such as power stations, chemical industry, printing and dyeing, and papermaking. The water filter is mainly suitable for pipes below DN500mm, which can replace the secondary filter and save costs. It is used to filter impurities in pipe water.

[0003] The Chinese patent with publication number CN218306485U discloses a water filter for hydropower stations that is easy to use. The water filter base and fastening threads are provided, and the water filter base is threadedly connected to the water filter body through the fastening threads, which is conducive to cleaning up the debris accumulated at the bottom of the water filter base, making it convenient to use. The water filter base bears the pressure of the entire water filter for a long time. The threaded connection between the water filter base and the water filter body facilitates the maintenance and replacement of the water filter base. However, the water filter in the comparative patent has only one filter screen inside, a single number of filter screens, and only one inlet for the filter screen. Therefore, impurities in the water may clog the mesh of the filter screen, affecting the filtering effect. If the single filter screen is clogged, it is difficult to continue to maintain the normal filtering effect of the water filter, which may affect the normal use of the water filter. Therefore, in view of the above problems, a filter screen structure with water entering from top to bottom inside the water filter is proposed. Utility Model Content

If a single filter screen is blocked, it is difficult to continue to maintain the normal filtering effect of the water filter, which may affect the normal use of the water filter. The filter screen is further prevented from being blocked by impurities, ensuring the normal use of the water filter. BRIEF DESCRIPTION OF THE DRAWINGS

Large-volume residues will be filtered out by the filter body 19, and small-volume floating objects will float to the top of the chamber. The filtered clean water is sent out from the water outlet 20. Under the impact force of the water flow below, the spring 28 will keep driving the thrust sleeve 27 to move upward, so that the thrust sleeve 27 is always in contact with the support plate 17.

Under the impact of the water flow below, the spring 28 will always drive the thrust sleeve 27 to move upward, so that the thrust sleeve 27 is always in contact with the support plate 17. The reduction motor 1 drives the first transmission shaft 3, the second transmission shaft 4, the third transmission shaft 16, the sewage fork pipe 15 and the throttle plate 5 to rotate in the same direction. There is a certain gap between the throttle plate 5 and the pressure cover 21, so that part of the water can generate a larger impact force under the rotation of the throttle plate 5, and enter the filter through the gap to impact the debris on the filter, so that the debris is not easy to remain on the surface of the filter body 19 and is easier to discharge.
