When the sewage flow impacts the spiral force-bearing member, the rotating disk and the cleaning disk clean the scale or adhering impurities on the filter plate, which can effectively prevent the scale or impurities from clogging the filter holes on the filter plate and improve the flow effect of the filter plate when filtering sewage.

[0004] The disadvantages of the above-mentioned prior art are that the impurities on the filter plate are cleaned by the cleaning disk, but the cleaned impurities still exist in the pipeline. When the water flow hits again, the filter plate will be blocked again, resulting in poor cleaning effect. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it is necessary to understand that Figure 1 The second filter part 4 is located above the first filter part 3, and vice versa. Figure 2 The position of the first sealing plate 7 relative to the second sealing plate 9 is on the left, and vice versa.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0026] Reference Figure 1-2 A filtering mechanism for water treatment provided by an embodiment of the utility model includes a conveying pipe 1 for conveying sewage, a baffle 2 is slidably provided on the conveying pipe 1, and a first filter part 3 is provided on the baffle 2; a backwash component is provided on the conveying pipe 1, and the backwash component is located on the movement stroke of the first filter part 3.

[0027] Specifically, the delivery pipe 1 is a cylindrical structure, one end of which is connected to the delivery pump and the other end is connected to the clean water tank. A filter assembly is provided inside the delivery pipe 1. In the process of the delivery pump delivering sewage to the clean water tank through the delivery pipe 1, impurities in the sewage can be removed by the filter assembly, thereby achieving sewage treatment. This is the prior art and will not be repeated. One of the core innovations of the embodiment of the present utility model is that the delivery pipe 1 is divided into two left and right sections, the baffle 2 is slidably set at the connection position between the two, and the first filter part 3 is set on the baffle 2. The first filter part 3 is a grid-shaped filter structure, and the backwash component can be a high-pressure water gun or other structure. The purpose of such a setting is that when the first filter part 3 is blocked, the baffle 2 is slid to separate the first filter part 3 from the delivery pipe 1, and then the first filter part 3 is flushed separately by the backwash component. After flushing, the baffle 2 is slid in the opposite direction, thereby driving the first filter part 3 to automatically reset. In this way, the impurities cleaned from the first filter part 3 will not enter the delivery pipe 1 again, thereby improving the cleaning effect.

[0028] Furthermore, a second filter portion 4 is provided on the baffle 2. Specifically, the second filter portion 4 is also a grid-shaped filter structure, which is provided above the first filter portion 3, and the radial dimensions of the two are the same. The purpose of such a setting is that when the first filter portion 3 is blocked, the baffle 2 is controlled to slide downward, so that the first filter portion 3 moves to the outside of the conveying pipe 1, and at the same time, the second filter portion 4 moves down to a position coaxial with the conveying pipe 1. In this way, when the first filter portion 3 is cleaned, the second filter portion 4 can also filter, so as to achieve the effect of non-stop cleaning.

[0029] As an alternative to the above-mentioned high-pressure water gun cleaning, the backwash assembly includes a branch pipe 5 connected to the delivery pipe 1, and the baffle 2 is slidably connected to the delivery pipe 1 and the branch pipe 5. Specifically, the radial dimension of the connection position between the branch pipe 5 and the delivery pipe 1 is smaller than the radial dimension of the delivery pipe 1, and the radial dimension of the branch pipe 5 away from the connection position is adapted to the radial dimension of the first filter part 3. The effect of such a setting is that after the first filter part 3 slides out of the delivery pipe 1, since the second filter part 4 is inside the delivery pipe 1, water still flows through the delivery pipe 1 on the right side. At this time, some filtered clean water will enter the branch pipe 5 and be flushed from the right side of the first filter part 3 to passively wash away impurities on the first filter part 3, thereby realizing self-cleaning of the first filter part 3.

[0030] Furthermore, a sealing cylinder 6 is provided between the delivery pipe 1 and the branch pipe 5. Specifically, the sealing cylinder 6 is provided between the delivery pipe 1 and the branch pipe 5, and the sealing cylinder 6 is slidably and sealingly connected to the baffle 2 to prevent sewage from flowing out of the delivery pipe 1 when the first filter part 3 and the second filter part 4 switch positions.

[0031] Furthermore, a blocking member is provided on the branch pipe 5. Specifically, the blocking member is a valve or other structure. When the first filter part 3 needs to be cleaned, the valve is opened to form a passage inside the branch pipe 5. At this time, part of the water flow inside the delivery pipeline 1 will pass through the branch pipe 5 to clean the first filter part 3. After cleaning, the valve is closed to seal the space inside the branch pipe 5, thereby preventing water from flowing out of the branch pipe 5 during normal filtration.

[0032] As an alternative to the above-mentioned valve, the blocking member includes a first blocking plate 7, a through hole 8 is provided on the first blocking plate 7, and a second blocking plate 9 is slidably provided on the first blocking plate 7. Specifically, the first blocking plate 7 is an annular structure, and its radial dimension is adapted to the radial dimension of the inside of the branch pipe 5, and the through hole 8 is located at the center of the first blocking plate 7. The second blocking plate 9 is a circular plate, and the second blocking plate 9 is located on the right side of the first blocking plate 7. The radial dimension of the second blocking plate 9 is larger than the radial dimension of the through hole 8 and smaller than the radial dimension of the first blocking plate 7. The second blocking plate 9 is provided with a sliding portion 10, which is a U-shaped rod structure. The first blocking plate 7 is provided with a sliding hole adapted to the sliding portion 10. The two ends of the connecting part 10 pass through the sliding holes and are fixedly connected to the second sealing plate 9. The purpose of such a setting is that under the pressure of the water flow, the second sealing plate 9 will fit together with the right side of the first sealing plate 7, so that the through hole 8 can be blocked. When the first filter part 3 needs to be cleaned, the second sealing plate 9 is controlled to slide to the right, so that the second sealing plate 9 is separated from the first sealing plate 7. At this time, the through hole 8 is opened, and the water flow in the branch pipe 5 will flow out through the gap between the second sealing plate 9 and the first sealing plate 7 to achieve self-cleaning of the first filter part 3.

[0033] Furthermore, an abutment rod 11 is fixedly connected to the second blocking plate 9, and the abutment rod 11 is located on the movement stroke of the baffle 2. Specifically, the abutment rod 11 is L-shaped, that is, the abutment rod 11 includes a vertical section and a horizontal section, the vertical section is fixedly connected to the sliding portion 10, and a square hole 12 is opened on the horizontal section, and a wedge surface 13 is provided on the side wall of the square hole 12, and the wedge surface 13 is located on the movement stroke of the baffle 2. The purpose of such a setting is that when the second filter part 4 moves down to be coaxial with the conveying pipe 1, the first filter part 3 is not coaxial with the branch pipe 5, and the first filter part 3 is located slightly above the central axis of the branch pipe 5. When the first filter part 3 needs to be cleaned, in order to facilitate comprehensive cleaning of the first filter part 3, the baffle 2 is controlled to move downward so that the first filter part 3 is coaxial with the branch pipe 5, and in the process of the baffle 2 moving down, the bottom end of the baffle 2 will be in contact with the wedge surface 13 on the abutment rod 11. 3 abuts against the abutment rod 11, the sliding portion 10 and the second blocking plate 9 to slide to the right, so that the through hole 8 can be passively opened, and at this time the first filter part 3 is coaxial with the branch pipe 5, so the first filter part 3 can be fully cleaned (in this process, the second filter part 4 will also be driven to move downward, which will cause a slight offset between the second filter part 4 and the central axis of the conveying pipe 1. Since the cleaning process of the first filter part 3 is short, the short offset of the second filter part 4 will not have a significant impact on the transportation of sewage). After cleaning, the baffle 2 is controlled to move upward. When the baffle 2 is away from the wedge-shaped surface 13, the second blocking plate 9 will be driven to move to the left under the action of the impact force of the water flow to block the through hole 8 again.

[0034] Furthermore, a fixing plate 14 is fixedly connected to the second blocking plate 9, and a spring 15 is provided between the fixing plate 14 and the first blocking plate 7. Specifically, there are two fixing plates 14 and two springs 15, and the fixing plates 14 are symmetrically arranged on the upper and lower sides of the sliding portion 10. The two springs 15 are respectively provided between the two fixing plates 14 and the first blocking plate 7. The purpose of such a setting is that when there is no water in the branch pipe 5, the elastic force of the spring 15 causes the second blocking plate 9 to block the through hole 8, thereby isolating the inside of the branch pipe 5 from the outside world. When the baffle 2 abuts the abutting rod 11 to drive the second blocking plate 9 to move, the spring 15 is charged. When the baffle 2 moves away from the abutting rod 11, the elastic force of the spring 15 is released, thereby accelerating the blocking speed of the second blocking plate 9.

[0035] Preferably, two backwash assemblies are provided, and the two backwash assemblies are symmetrically arranged about the delivery pipe 1. The two backwash assemblies are symmetrically arranged on the upper and lower sides of the delivery pipe 1, and the two backwash assemblies are used to clean the first filter part 3 and the second filter part 4 respectively.

[0036] It should be noted that when the second filter part 4 is clogged after long-term use, the baffle 2 is controlled to slide upward, and the above process will be repeated during the upward sliding of the baffle 2, so that the second filter part 4 can be cleaned. At this time, the cleaned first filter part 3 will be moved into the conveying pipe 1 again for filtering, and alternating filtration is performed in this way.

[0037] Furthermore, it also includes a power assembly (not shown in the figure) for driving the baffle 2 to slide. Specifically, the power assembly can be a reciprocating drive assembly such as an electric push rod, which is used to provide a driving force when the baffle 2 slides.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
