Description

Technical Field

[0001] This utility model belongs to the field of filter cleaning technology, and in particular relates to a self-cleaning filter. Background Technology

[0002] In industrial water treatment, cooling systems and various applications requiring water purification, filters are essential key components. As the usage time increases, scale and impurities inevitably accumulate inside the filter, which not only reduces filtration efficiency but may also affect the normal operation of the entire system. This is especially true in environments with hard water or high concentrations of suspended solids, where scale buildup on the filter's inner wall is faster and has a more significant impact on filtration performance.

[0003] Traditional filter maintenance often requires shutdown and disassembly for manual cleaning. This not only consumes a lot of manpower and time, but also leads to production interruptions and reduces overall work efficiency. For example, in some continuous production industrial processes, any unplanned shutdown will cause economic losses. In addition, frequent manual cleaning will increase the risk of operators being exposed to chemicals, and manual cleaning is difficult to guarantee that all scale and impurities will be completely removed each time, thus affecting the service life and performance stability of the filter. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a self-cleaning filter that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a self-cleaning filter includes a filter, a mounting bracket, a support leg, and a drain pipe. The lower outer surface of the filter is fixedly connected to the surface of the mounting bracket, the surface of the mounting bracket is fixedly connected to the upper end of the support leg, the lower inner wall of the filter is fixedly connected to the surface of the drain pipe, and a cleaning device is provided at the upper end of the filter, with an auxiliary mechanism provided on the cleaning device.

[0006] The cleaning device is used to clean the inner wall of the filter;

[0007] The auxiliary mechanism is used to assist the cleaning process.

[0008] To improve the stability of the fixed plate movement, the cleaning device preferably includes a guide rod, a fixed plate, an electric push rod, and a support frame. The surface of the guide rod is slidably connected to the inner walls on both sides of the fixed plate, the upper surface of the fixed plate is fixedly connected to the lower end of the electric push rod, and the upper surface of the electric push rod is fixedly connected to the upper surface of the support frame. The guide rod allows the fixed plate to slide smoothly along its surface, ensuring that the fixed plate and the sealing cover connected to it can move stably up and down, preventing sealing problems caused by positional deviation, thereby ensuring a tight connection between the sealing cover and the filter and enhancing the sealing performance at the interface.

[0009] To improve cleaning efficiency, preferably, the auxiliary mechanism includes a water tank, a water pump, a water supply pipe, a spray plate, a connecting plate, a hydraulic cylinder, and an electric pump. The water tank is located at the rear end of the filter. The inner wall of the water tank is fixedly connected to the surface of the water pump. The output end of the water pump is fixedly connected to the lower end of the water supply pipe. The upper end of the water supply pipe is fixedly connected to the inner wall of the spray plate. The surface of the spray plate is fixedly connected to both sides of the connecting plate. The upper end of the connecting plate is fixedly connected to the lower end of the hydraulic cylinder. The upper end of the hydraulic cylinder is fixedly connected to the output end of the electric pump. The spray plate is located in the area above the filter and is equipped with multiple high-pressure nozzles, which can evenly spray the cleaning liquid to various parts of the inner wall of the filter, thereby achieving a comprehensive and efficient cleaning effect.

[0010] To improve the stability of the feeding process, preferably, a sealing cover is provided on the inner wall of the fixed plate, and the surface of the sealing cover is fixedly connected to the inner wall of the fixed plate. A limit plate is provided on the lower side of the guide rod, and the inner wall of the limit plate is fixedly connected to the surface of the guide rod. By fixing the sealing cover to the inner wall of the fixed plate, the sealing cover and the fixed plate form a stable linkage state. When the electric push rod drives the fixed plate to move up and down along the guide rod, the sealing cover can move synchronously, thereby ensuring the docking accuracy between the sealing cover and the filter and avoiding misalignment or poor sealing caused by relative displacement.

[0011] To improve work efficiency, preferably, the lower end of the guide rod is fixedly connected to the upper end of the support leg, and the upper end of the guide rod is fixedly connected to the inner wall of the support frame, so as to prevent the guide rod from shaking or deviating when subjected to external loads or reciprocating action of moving parts, thereby ensuring the guiding function of the guide rod on the fixed plate and the sealing cover.

[0012] To improve the smoothness of the electric pump's operation, preferably, the surface of the electric pump is fixedly connected to the upper surface of the support frame. By fixing the electric pump to the upper surface of the support frame, displacement or loosening caused by vibration or hydraulic shock during operation is prevented, thereby ensuring that it continuously and stably provides power output to the hydraulic cylinder.

[0013] To improve the reliability of the device, preferably, the lower surface of the sealing cap contacts the upper inner wall of the filter, and the two lower side surfaces of the fixing plate contact the upper surface of the limiting plate. The limiting plate restricts the position of the fixing plate as it descends along the guide rod, effectively controlling the lowest descending position of the fixing plate and the sealing cap, ensuring appropriate pressure between the sealing cap and the filter, thereby enhancing the sealing effect and preventing mechanical damage or structural deformation caused by overtravel. Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates a cleaning device, an auxiliary mechanism, a guide rod, a fixed plate, a support frame, a spray plate, a connecting plate, a hydraulic cylinder, and an electric pump. The cleaning device cleans the inner wall of the filter, while the auxiliary mechanism assists the cleaning process. The guide rod allows the fixed plate to slide smoothly along its surface, ensuring stable up-and-down movement of the fixed plate and its connected sealing cover, preventing sealing issues caused by positional misalignment. This guarantees a tight connection between the sealing cover and the filter, enhancing the sealing performance at the interface. The spray plate, positioned above the filter and equipped with multiple high-pressure nozzles, evenly sprays the cleaning fluid onto all parts of the filter's inner wall, achieving a comprehensive and efficient cleaning effect. This solves the problem of traditional filter maintenance, which typically requires shutdown and manual disassembly for cleaning. This not only consumes manpower and time but also interrupts production and reduces efficiency. For example, in continuous production processes, unplanned shutdowns lead to economic losses, and frequent manual cleaning may increase the risk of operators coming into contact with chemicals. Furthermore, it is difficult to ensure thorough removal of scale and impurities each time, affecting the filter's lifespan and performance. Attached Figure Description

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown in the figure, this utility model provides a self-cleaning filter, including a filter 5, a mounting frame 6, a support leg 7, and a drain pipe 8. The lower outer surface of the filter 5 is fixedly connected to the surface of the mounting frame 6, the surface of the mounting frame 6 is fixedly connected to the upper end of the support leg 7, and the lower inner wall of the filter 5 is fixedly connected to the surface of the drain pipe 8. A cleaning device 1 is provided at the upper end of the filter 5, and an auxiliary mechanism 2 is provided on the cleaning device 1. The cleaning device 1 is used to clean the inside of the filter 5, and the auxiliary mechanism 2 is used to assist the cleaning process. The cleaning device 1 includes a guide rod 101, a fixing plate 102, an electric push rod 103, and a support frame 104. The surface of the guide rod 101 is slidably connected to the inner walls of both sides of the fixing plate 102, and the upper surface of the fixing plate 102 is slidably connected to the electric push rod 103. The lower end of the push rod 103 is fixedly connected, and the upper surface of the electric push rod 103 is fixedly connected to the upper surface of the support frame 104. The guide rod 101 enables the fixed plate 102 to slide smoothly along its surface, ensuring that the fixed plate 102 and the sealing cover 3 connected to it can move up and down stably, preventing the sealing problem caused by positional displacement, thereby ensuring a tight connection between the sealing cover 3 and the filter 5 and enhancing the sealing performance at the interface. The auxiliary mechanism 2 includes a water tank 201, a water pump 202, a water pipe 203, a spray plate 204, a connecting plate 205, a hydraulic cylinder 206, and an electric pump 207. The water tank 201 is located at the rear end of the filter 5, and the inner wall of the water tank 201 is fixedly connected to the surface of the water pump 202. The output end of the water pump 202 is connected to the... The lower end of the water supply pipe 203 is fixedly connected, and the upper end of the water supply pipe 203 is fixedly connected to the inner wall of the spray plate 204. The surface of the spray plate 204 is fixedly connected to both sides of the connecting plate 205. The upper end of the connecting plate 205 is fixedly connected to the lower end of the hydraulic cylinder 206. The upper end of the hydraulic cylinder 206 is fixedly connected to the output end of the electric pump 207. The spray plate 204 is located above the filter 5 and is equipped with multiple high-pressure nozzles, which can evenly spray the cleaning liquid to various parts of the inner wall of the filter 5, thereby achieving a comprehensive and efficient cleaning effect. A sealing cover 3 is provided on the inner wall of the fixing plate 102, and the surface of the sealing cover 3 is fixedly connected to the inner wall of the fixing plate 102. A limit plate 4 is provided on the lower side of the guide rod 101, and the inner wall of the limit plate 4 is fixedly connected to the surface of the guide rod 101. The sealing cover 3 is fixed to the inner wall of the fixed plate 102, so that the sealing cover 3 and the fixed plate 102 form a stable linkage state. When the electric push rod 103 drives the fixed plate 102 to move up and down along the guide rod 101, the sealing cover 3 can move synchronously, thereby ensuring the docking accuracy between the sealing cover 3 and the filter 5 and avoiding misalignment or poor sealing caused by relative displacement. The lower end of the guide rod 101 is fixedly connected to the upper end of the support leg 7, and the upper end of the guide rod 101 is fixedly connected to the inner wall of the support frame 104 to prevent the guide rod 101 from shaking or deviating when subjected to external loads or reciprocating action of moving parts, thereby ensuring the guiding effect of the guide rod 101 on the fixed plate 102 and the sealing cover 3. The surface of the electric pump 207 is fixedly connected to the upper surface of the support frame 104.By fixing the electric pump 207 to the upper surface of the support frame 104, displacement or loosening due to vibration or hydraulic shock during operation is prevented, thus ensuring a continuous and stable power output to the hydraulic cylinder 206. The lower surface of the sealing cover 3 contacts the upper inner wall of the filter 5, and the lower two sides of the fixing plate 102 contact the upper surface of the limiting plate 4. The limiting plate 4 limits the position of the fixing plate 102 as it descends along the guide rod 101, effectively controlling the lowest descending position of the fixing plate 102 and the sealing cover 3, ensuring appropriate clamping force between the sealing cover 3 and the filter 5, thereby enhancing the sealing effect and preventing mechanical damage or structural deformation caused by over-stroke.

[0023] The working principle of this utility model:

[0024] During long-term use, scale often accumulates on the inner wall of filter 5 due to water quality issues. This scale not only affects the quality of the filtered water but can also become a breeding ground for bacteria, thus adversely affecting the overall operation of the system. Therefore, to ensure the normal working performance and hygiene of filter 5, it must be cleaned and maintained regularly. Under normal operating conditions, the electric push rod 103 is in the retracted state, and the sealing cover 3 maintains a sealed connection with the top of filter 5. When cleaning is required, the electric push rod 103 is first activated, pushing the fixed plate 102 downward along the guide rod 101. The sealing cover 3 is located on the inner side of the fixed plate 102. As the fixed plate 102 descends, the sealing cover 3 descends synchronously and eventually forms a tight fit with the top of filter 5. When the lower surface of the fixed plate 102 contacts the limiting plate 4 on the guide rod 101, the electric push rod 103 continues to apply pressure to ensure good sealing between the sealing cover 3 and filter 5, preventing leakage during subsequent filtration. After the sealing operation is completed, the cleaning stage begins. At this time, the electric push rod 103 is activated again, moving the fixed plate 102 downward. 02 moves upward along the guide rod 101, thereby causing the sealing cover 3 to rise together. After the sealing cover 3 rises to a certain height, the end cover is automatically opened, completely exposing the inside of the filter 5 and providing sufficient space for cleaning operations. Subsequently, the electric pump 207 is started, driving the hydraulic cylinder 206 to move the spray plate 204 downward and pass through the sealing cover 3 into the inside of the filter 5. At the same time, the water pump 202 in the water tank 201 is turned on, and the cleaning solution is delivered to the spray plate 204 through the water pipe 203. The cleaning solution is evenly distributed through the high-pressure nozzles on the spray plate 204. The spray is applied to the inner wall of the filter 5 for efficient rinsing. The spray plate 204 can move up and down reciprocally under the drive of the hydraulic cylinder 206 to ensure that the cleaning fluid covers all areas of the inner wall of the filter 5. The nozzles are arranged in a multi-angle manner to enhance the rinsing effect and improve the cleaning efficiency. After the rinsing operation is completed, the water pump 202 and the electric pump 207 are turned off. The hydraulic cylinder 206 drives the spray plate 204 to move up and detach it from the inside of the filter 5. Then, the sealing cover 3 is lowered by the electric push rod 103 and re-sealed with the top of the filter 5, so that the system returns to the initial operating state.

[0025] The specific models and specifications of the electric push rod 103, water pump 202, water pipe 203, spray plate 204, hydraulic cylinder 206, and electric pump 207 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
