Technical Field

[0001] The utility model relates to the technical field of industrial water treatment and purification, in particular to a high-efficiency self-cleaning filter device. Background Art

[0002] Self-cleaning filters automatically clean the filter screen to maintain filtration efficiency. They monitor contamination levels and, once a set threshold is reached, initiate a cleaning process to clean the filter screen. They are commonly used in industrial liquid filtration, sewage treatment, and drinking water treatment, improving filtration efficiency and extending equipment life. Their operating principles include detection, cleaning, draining, and resetting. However, some self-cleaning filters may not be ideal, resulting in residual contaminants on the filter screen, affecting filtration effectiveness. Furthermore, self-cleaning filters typically require regular maintenance and servicing, resulting in relatively high maintenance costs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "top", "bottom", "one side", "the other side", "front", "back", "middle", "inside", "top", "bottom end", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified or limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense, for example, they can mean fixed connection, detachable connection, or integral connection; they can mean mechanical connection or electrical connection; they can mean direct connection, indirect connection through an intermediate medium, or internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the utility model provides a high-efficiency self-cleaning filter device, including a filter valve 1, an upper end cover 2, a hydraulic motor 3, a sewage suction pipe 4, a filter screen 5, a backflush pipe 6, a sewage collecting device 7, a main pipe assembly 8, a water inlet 9, an inlet pressure gauge 10, a water outlet 11, an outlet pressure gauge 12, an air source main valve 13, a sewage valve 14, and a controller 15.

[0022] The top end of the filter valve 1 is fixedly connected to an upper end cover 2 , the top end of the upper end cover 2 is fixedly connected to a hydraulic motor 3 , and the output end of the hydraulic motor 3 is fixedly connected to a sewage suction pipe 4 .

[0023] A filter screen 5 is fixedly connected to the inside of the filter valve 1, and a back-blowing pipe 6 is provided on the outer surface of the filter screen 5. There are 6 back-blowing pipes 6 evenly arranged, and each back-blowing pipe 6 is provided with a back-blowing hole with a diameter of 2 mm. A wire brush is provided inside the filter screen 5, and a dirt collecting device 7 is fixedly connected to the bottom of the filter screen 5.

[0026] The working process of the utility model patent is as follows: the inlet pressure gauge 10 and the outlet pressure gauge 12 continuously send the inlet and outlet pressures of the filter valve 1 to the controller 15. The controller 15 calculates the pressure difference according to the inlet and outlet pressures. When the inlet and outlet pressure difference reaches the set value, the controller 15 controls the start of the hydraulic motor 3 and opens the drain valve 14. At the same time, the air source main valve 13 is controlled to open to supply air to the backflush pipe 6. The hydraulic motor 3 drives the wire brush on the inner surface of the filter screen 5 to rotate through the suction pipe 4 to clean the inner surface of the filter screen 5. At the same time, the backflush pipe 6 backflushes the outer surface of the filter screen 5 to further improve the cleaning effect, and finally discharges the dirt through the drain valve 14.

Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
