[0001] The utility model relates to the technical field of water supply and drainage filtering, in particular to a high-efficiency water supply and drainage filtering device. Background Art

[0002] Water supply refers to the process of extracting, treating and delivering water resources from water sources to users through water conservancy engineering facilities. Water supply is the main source of water for urban and rural life and production, ensuring the basic living needs of residents, such as drinking, washing, irrigation, etc. For industrial production, stable water supply is the basis for ensuring smooth production; water supply and drainage filter device is a filtering device specially designed for use in water supply and drainage systems. Its main function is to remove suspended matter, particulate matter, organic matter and other impurities in water to improve water quality, protect subsequent treatment equipment, and extend the service life of the entire water supply and drainage system. Water supply and drainage filter device is a key equipment to ensure water quality safety and improve the efficiency of water supply and drainage systems.

[0003] Chinese patent publication number CN219579965U discloses a water conservancy project filter device. The device comprises a first connecting flange fixedly connected to the left end of a water conservancy pipeline, an annular water pipe fixedly connected to the inner wall of the water conservancy pipeline, an annular flushing nozzle fixedly connected to the inner wall of the annular water pipe, an input end of the annular water pipe extending through the water conservancy pipeline and extending to the outside of the water conservancy pipeline, a filter sleeve sleeved on the left end of the water conservancy pipeline, and a filter screen fixedly connected to the inner wall of the filter sleeve. The device utilizes the first connecting flange, the second connecting flange, the sealing gasket, the mounting hole, and the gripping handle to achieve bolted mounting of the filter sleeve and the filter screen, and rapid assembly and replacement of the filter screen. Furthermore, the annular water pipe, the flushing nozzle, and the connector enable directional water flushing of the filter screen, effectively removing impurities from the filter screen surface and preventing clogging of the filter screen, thereby facilitating effective filtration of the water conservancy pipeline. However, the device requires manual cleaning of impurities and cannot automatically direct and concentrate filtered impurities.

[0004] The existing water supply and drainage filtering device will accumulate a certain amount of impurities during the filtering process, which is easy to affect the filtering effect of the filtering structure and requires manual cleaning. In addition, the filtering structure is not convenient to disassemble and it is not convenient to clean the filter.

[0005] In order to solve the above-mentioned deficiencies in the prior art, it is worthwhile to provide a high-efficiency water supply and drainage filtering device. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a high-efficiency water supply and drainage filtering device, which effectively solves the shortcomings of the prior art.

[0007] The purpose of the utility model is achieved through the following technical solutions: a high-efficiency water supply and drainage filtering device, including a water supply and drainage filtering chamber, the front and rear sides of the water supply and drainage filtering chamber are fixedly connected to installation pipes, the left and right sides of the water supply and drainage filtering chamber are fixedly connected to garbage collection chambers, the interior of the water supply and drainage filtering chamber is fixedly connected to a filter frame, and a self-cleaning roller brush is provided inside the filter frame.

[0008] Optionally, slots are provided between the water supply and drainage filter bin and the two garbage collection bins, the front and rear sides of the filter frame are both arc-shaped, and the side surfaces of the filter frame are tangent to the inner sides of the slots.

[0009] The above technical solution is adopted: by arranging an arc-shaped filter frame inside the water supply and drainage filter chamber, when the water flow enters the water supply and drainage filter chamber, the impurities in the water flow can be blocked by the filter frame, and the blocked impurities enter the garbage collection bin on both sides of the filter frame along the arc surface under the action of the water flow and the arc surface of the filter frame. The filter device uses the arc surface structure of the filter frame to guide and automatically clean the filtered impurities, so that the filter frame remains clean, and avoids the accumulation of impurities on the filter screen of the filter device that affects the filtering efficiency and filtering effect.

[0010] Optionally, a partition plate is fixedly connected to the middle of the garbage collection bin, and the height of the garbage collection bin is adapted to the height of the partition plate.

[0011] The above technical solution is adopted: by setting a partition plate in the middle of the garbage collection bin, the slots on both sides of the garbage collection bin are separated to prevent water from flowing directly through the garbage collection bin without being filtered.

[0012] Optionally, a garbage cleaning port is provided at the top of the garbage collection bin, and a closing plate is rotatably connected to the top of the garbage cleaning port, and the shape of the closing plate is adapted to the shape of the garbage cleaning port.

[0013] The above technical solution is adopted: by setting a garbage cleaning port on the top of the garbage collection bin, when a lot of garbage accumulates in the garbage collection bin, the closing plate can be opened and the accumulated garbage can be collected and cleaned from the garbage cleaning port. Compared with directly cleaning the filter net, this structure is more convenient and quick. The filter net is continuously flushed with water flow, which can also prevent impurities from accumulating in the filter net and affecting the filtration efficiency.

[0014] Optionally, the outer bristles of the self-cleaning roller brush are tangent to the inner side of the filter frame, and a plurality of V-shaped plates are fixedly connected to the outer side of the rotating roller of the self-cleaning roller brush, and the V-shaped plates are distributed in a ring shape on the outer side of the rotating roller of the self-cleaning roller brush.

[0015] The above technical solution is adopted: by arranging a rotating self-cleaning roller brush inside the filter frame, the rotation of the self-cleaning roller brush can scrub and clean the inner wall of the filter frame, reducing impurities attached to the filter frame. When water flows through the rotating roller of the self-cleaning roller brush, the back of the V-shaped plate on one side is impacted by the water flow, and the front of the V-shaped plate on the other side is impacted by the water flow. The front and back of the V-shaped plate are impacted by different forces of the water flow, so that the self-cleaning roller brush continues to rotate in one direction under the action of the water flow, and automatically scrubs and cleans the inner wall of the filter frame.

[0016] Optionally, a motor is fixedly connected to the top center of the water supply and drainage filter bin, and the output end of the motor is fixedly connected to the rotating shaft of the self-cleaning roller brush.

[0017] The above technical solution is adopted: by setting a motor on the top of the water supply and drainage filter bin, under normal circumstances, the output end of the motor is in a neutral state, and the self-cleaning roller brush rotates driven by the water flow to clean the inside of the filter frame. When the inside of the filter frame needs strong cleaning, the electric drive is started to rotate the self-cleaning roller brush to efficiently and fully clean the inner wall of the filter frame, avoiding the situation where the water flow force is not sufficient to drive the self-cleaning roller brush to rotate and complete the brushing.

[0018] Optionally, both ends of the installation pipes are fixedly connected with connecting flanges, and the installation pipes are fixedly connected to the water supply and drainage pipes through the connecting flanges.

[0019] Positive and beneficial effects: 1. The high-efficiency water supply and drainage filtration device uses the curved surface structure of the filter frame to guide and automatically clean the filtered impurities, so that the filter frame remains clean, avoiding the accumulation of impurities on the filter screen of the filtration device that affects the filtration efficiency and filtration effect, and uses a partition plate to separate the slots on both sides of the garbage collection bin to avoid water flowing directly through the garbage collection bin without being filtered.

[0020] 2. In this high-efficiency water supply and drainage filtration device, when water flows through the rotating roller of the self-cleaning roller brush, the back of the V-shaped plate on one side is impacted by the water flow, and the front of the V-shaped plate on the other side is impacted by the water flow. The front and back of the V-shaped plate are impacted by different forces of the water flow, so that the self-cleaning roller brush continuously rotates in one direction under the action of the water flow, automatically scrubbing and cleaning the inner wall of the filter frame.

[0021] 3. The high-efficiency water supply and drainage filtering device starts the electric motor to drive the self-cleaning roller brush to rotate, and cleans the inner wall of the filter frame efficiently and thoroughly, avoiding the situation where the water flow force is not sufficient to drive the self-cleaning roller brush to rotate and complete the brushing.

DETAILED DESCRIPTION

[0028] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1

[0030] like Figures 1 to 5 As shown, a high-efficiency water supply and drainage filtering device includes a water supply and drainage filtering chamber 1, the front and rear sides of the water supply and drainage filtering chamber 1 are fixedly connected to installation pipes 2, the left and right sides of the water supply and drainage filtering chamber 1 are fixedly connected to garbage collection chambers 3, the interior of the water supply and drainage filtering chamber 1 is fixedly connected to a filter frame 4, and the interior of the filter frame 4 is provided with a self-cleaning roller brush 5.

[0031] like Figures 1 to 3 As shown, slots 6 are provided between the water supply and drainage filter bin 1 and the two garbage collection bins 3. The front and rear sides of the filter screen frame 4 are both arc-shaped, and the side surfaces of the filter screen frame 4 are tangent to the inner sides of the slots 6. By arranging an arc-shaped filter screen frame 4 inside the water supply and drainage filter bin 1, when the water flow enters the water supply and drainage filter bin 1, impurities in the water flow can be blocked by the filter screen frame 4. Under the action of the water flow and the arc surface of the filter screen frame 4, the blocked impurities enter the garbage collection bins 3 on both sides of the filter screen frame 4 along the arc surface. The filter device utilizes the arc surface structure of the filter screen frame 4 to guide and automatically clean the filtered impurities, so that the filter screen frame 4 remains clean, and avoids the situation where impurities accumulate on the filter screen of the filter device and affect the filtering efficiency and filtering effect.

[0032] like Figures 1 to 3As shown, a partition plate 7 is fixedly connected to the middle of the garbage collection bin 3. The height of the garbage collection bin 3 is adapted to the height of the partition plate 7. By arranging the partition plate 7 in the middle of the garbage collection bin 3, the slots 6 on both sides of the garbage collection bin 3 are separated to prevent water from directly passing through the garbage collection bin 3 without being filtered.

[0033] like Figure 4 As shown, a garbage cleaning port 8 is provided at the top of the garbage collection bin 3, and a closing plate 9 is rotatably connected to the top of the garbage cleaning port 8. The shape of the closing plate 9 is adapted to the shape of the garbage cleaning port 8. By arranging the garbage cleaning port 8 at the top of the garbage collection bin 3, when a large amount of garbage accumulates in the garbage collection bin 3, the closing plate 9 can be opened and the accumulated garbage can be collected and cleaned from the garbage cleaning port 8. This structure is more convenient and quicker than directly cleaning the filter screen. The filter screen can be continuously flushed with water flow, which can also prevent impurities from accumulating in the filter screen and affecting the filtration efficiency.

[0034] Example 2

[0035] like Figures 4 and 5 As shown, the outer bristles of the self-cleaning roller brush 5 are tangent to the inner side of the filter frame 4, and a number of V-shaped plates 10 are fixedly connected to the outer side of the rotating roller of the self-cleaning roller brush 5. The V-shaped plates 10 are distributed in a ring shape on the outer side of the rotating roller of the self-cleaning roller brush 5. By arranging a rotating self-cleaning roller brush 5 inside the filter frame 4, the self-cleaning roller brush 5 can scrub the inner wall of the filter frame 4 when it rotates, thereby reducing impurities attached to the filter frame 4. When water flows through the rotating roller of the self-cleaning roller brush 5, the back side of the V-shaped plate 10 on one side is impacted by the water flow, and the front side of the V-shaped plate 10 on the other side is impacted by the water flow. The impact forces of the water flow on the front and back sides of the V-shaped plate 10 are different, so that the self-cleaning roller brush 5 continues to rotate in one direction under the action of the water flow, and automatically scrubs the inner wall of the filter frame 4.

[0036] Example 3

[0037] like Figures 4 and 5 As shown, a motor 12 is fixedly connected to the top center of the water supply and drainage filter chamber 1, and the output end of the motor 12 is fixedly connected to the rotating shaft of the self-cleaning roller brush 5. By arranging the motor 12 at the top of the water supply and drainage filter chamber 1, under normal circumstances, the output end of the motor 12 is in a neutral state, and the self-cleaning roller brush 5 rotates under the drive of the water flow to clean the inside of the filter frame 4. When the inside of the filter frame 4 needs strong cleaning, the electric motor 10 is started to drive the self-cleaning roller brush 5 to rotate, and the inner wall of the filter frame 4 is efficiently and fully cleaned to avoid the situation where the force of the water flow is insufficient to drive the self-cleaning roller brush 5 to rotate and complete the brushing.

[0038] like Figures 1 to 3As shown, both ends of the installation pipe 2 are fixedly connected with a connecting flange 11, and the installation pipe 2 is fixedly connected to the water supply and drainage pipe through the connecting flange.

[0039] The working principle of this utility model is as follows:

[0040] S1. When water flows into the water supply and drainage filter chamber 1, impurities in the water flow can be blocked by the filter frame 4. Under the action of the water flow and the curved surface of the filter frame 4, the blocked impurities enter the garbage collection chamber 3 on both sides of the filter frame 4 along the curved surface. The filter device uses the curved surface structure of the filter frame 4 to guide and automatically clean the filtered impurities, so that the filter frame 4 is kept clean, and the situation in which impurities accumulate on the filter screen of the filter device and affect the filtering efficiency and filtering effect is avoided;

[0041] S2. When the water flows through the rotating roller of the self-cleaning roller brush 5, the back of the V-shaped plate 10 on one side is impacted by the water flow, and the front of the V-shaped plate 10 on the other side is impacted by the water flow. The front and back of the V-shaped plate 10 are impacted by different forces of the water flow, so that the self-cleaning roller brush 5 continues to rotate in one direction under the action of the water flow, and automatically scrubs and cleans the inner wall of the filter frame 4.
