Description

Technical Field

[0001] This invention relates to the field of filtration, and in particular to a high-pressure automatic cleaning filter. Background Technology

[0002] In the field of agricultural irrigation filtration, filters are key equipment for ensuring the stable operation of irrigation systems and preventing clogging of drippers or sprinklers. Irrigation water is mostly drawn directly from rivers, ponds, or wells, and the water not only contains particulate impurities such as sand and gravel, but also often mixes with fine fibrous debris such as straw and grass leaves. Existing ordinary filters, such as mesh or disc filters, are easily covered by straw and grass leaves when faced with such complex impurities. At the same time, these straw and grass leaves mix with sand and gravel to form a dense clogging layer, causing a rapid decrease in filtration efficiency and a sharp increase in water flow resistance, which seriously affects irrigation results.

[0003] To address the problem of filter clogging, existing technologies mostly employ manual disassembly and cleaning. Manual cleaning requires disassembling and reassembling components, which is time-consuming, labor-intensive, and inconvenient. Therefore, there is an urgent need in this field for a filter that can automatically, conveniently, and efficiently complete the cleaning process to minimize manual intervention and ensure the efficient operation of irrigation systems. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a high-pressure automatic cleaning filter.

[0005] The technical solution of the present invention is as follows: a high-pressure automatic cleaning filter, characterized in that it comprises: a housing, a filter module, and a cleaning module;

[0006] The housing is provided with a partition, which divides the internal space of the housing into a water inlet chamber and a water outlet chamber. The partition is provided with a water passage hole for connecting the water inlet chamber and the water outlet chamber.

[0007] The filtration module includes an inlet pipe, an outlet pipe, and a filter pipe. The inlet pipe and the outlet pipe are disposed on the housing. The inlet pipe is connected to the inlet chamber, and the outlet chamber is connected to the outlet chamber. The filter pipe is fixedly disposed in the inlet chamber and is connected to the water passage hole. The filter pipe has filter holes on its wall. The filter pipe is used to filter the inlet water and then discharge the filtered water to the outlet chamber.

[0008] The cleaning module includes a drive mechanism, a rotating shaft, high-pressure nozzles, a pressure sensor, a high-pressure water supply mechanism, and a drainage mechanism. The rotating shaft is rotatably mounted on the housing and extends into the filter tube. The rotating shaft is a hollow shaft. Several high-pressure nozzles communicating with the interior of the rotating shaft are provided on the portion of the rotating shaft located inside the filter tube. The pressure sensor is provided in the water inlet chamber. The drive mechanism is connected to the rotating shaft to drive the rotating shaft to rotate. The high-pressure water supply mechanism is connected to the rotating shaft to provide high-pressure water flow. The drainage mechanism is connected to the water inlet chamber to discharge cleaning wastewater.

[0009] Furthermore, the drive mechanism includes a motor, which is connected to the rotating shaft.

[0010] Furthermore, the high-pressure water supply mechanism includes a water supply pipe and a high-pressure pump, wherein the water supply pipe is connected to the rotating shaft and the high-pressure pump is connected to the water supply pipe.

[0011] Furthermore, the drainage mechanism is a bidirectional pumping device, and the water inlet chamber is provided with a pumping pipe connected to the bidirectional pumping device.

[0012] Furthermore, the converter includes a sleeve, a bearing, a seal, and a water inlet pipe. The sleeve is fixedly disposed on the outside of the housing and sleeved on the rotating shaft. A gap is left between the internal cavity of the sleeve and the outer wall of the rotating shaft to form a water passage cavity. The rotating shaft is provided with a water passage hole communicating with its own interior. The sleeve is provided with a water inlet pipe connected to a high-pressure water supply mechanism. The water inlet pipe and the water passage hole are respectively connected to the water passage cavity.

[0013] The sleeve is fixedly provided with bearings for supporting the rotating shaft at both axial ends. The bearing is provided with the sealing element on the side facing the water passage cavity. The outer wall of the rotating shaft is provided with a limiting protrusion for limiting the sealing element.

[0014] Furthermore, the sealing element is an oil seal ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Integrated filtration and automatic cleaning: By setting up independent inlet and outlet water chambers and built-in filter tubes, a highly efficient filtration channel is constructed; at the same time, the rotating high-pressure jet cleaning mechanism integrated inside the filter tube can automatically remove various impurities that are intercepted.

[0017] 2. Intelligent sensing and automatic triggering capabilities: A pressure sensor installed in the inlet chamber monitors the pressure difference across the filter tube in real time. When the pressure difference reaches a preset threshold, it indicates severe filter clogging, and the system can automatically or manually initiate the cleaning program, achieving an intelligent upgrade from "passive clogging" to "active early warning and cleaning".

[0018] 3. Highly efficient and thorough cleaning without disassembly: The drive mechanism rotates the shaft and high-pressure nozzle inside the filter tube, and the high-pressure pump provides a strong water flow. Multiple high-pressure water jets from the nozzle can cover the entire inner wall of the filter tube without dead angles, which has a strong removal effect on impurities and completely solves the problem of inconvenient cleaning of traditional filters.

[0019] 4. Compact structure and reliable operation: The main functional modules are all integrated inside the shell, and the external pipeline interface is simple. It is especially suitable for long-term stable operation in complex environments such as farmland and irrigation pumping stations, which greatly reduces the frequency of maintenance and labor intensity.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0030] Please refer to the attached diagram below. Figure 1 A high-pressure automatic cleaning filter according to an embodiment of the present invention is described. The filter includes a housing 1, a filter module, and a cleaning module.

[0031] like Figure 1 As shown, the housing 1 is equipped with a partition 6, which divides the internal space of the housing 1 into an inlet chamber 2 and an outlet chamber 3. The partition 6 is provided with a water passage hole 7 for connecting the inlet chamber 2 and the outlet chamber 3. This structure clearly divides the interior of the housing 1, making the water flow path clear and facilitating the separation of filtration and sewage discharge functions.

[0032] The filtration module includes an inlet pipe 4, an outlet pipe 5, and a filter pipe 8. The inlet pipe 4 and outlet pipe 5 are mounted on the housing 1. The inlet pipe 4 connects to the inlet chamber 2, and the outlet pipe 5 connects to the outlet chamber 3. The filter pipe 8 is fixedly installed inside the inlet chamber 2 and connects to a water passage 7. The filter pipe 8 has filter holes on its wall. Thus, irrigation water to be filtered enters the inlet chamber 2 through the inlet pipe 4 and flows into the filter pipe 8. Driven by pressure, the water must pass through the filter holes on the wall of the filter pipe 8 to enter the channel between the inlet chamber 2 and the outlet chamber 3, and finally exits through the outlet pipe 5 via the water passage 7. During this process, impurities such as sand, straw, and grass leaves in the water are intercepted inside the filter pipe 8, thereby achieving an effective filtration function.

[0033] The cleaning module includes a drive mechanism 9, a rotating shaft 10, high-pressure nozzles 11, a pressure sensor, a high-pressure water supply mechanism 12, and a drainage mechanism. The rotating shaft 10 is rotatably mounted on the housing 1 and extends into the filter tube 8. The rotating shaft 10 is a hollow shaft, and its portion inside the filter tube 8 is equipped with several high-pressure nozzles 11 that communicate with the interior of the rotating shaft 10. A pressure sensor is installed in the water inlet chamber 2 to monitor the pressure difference caused by impurity accumulation inside and outside the filter tube 8. The drive mechanism 9 is connected to the rotating shaft 10 to drive its rotation, thereby causing the high-pressure nozzles 11 to rotate circumferentially within the filter tube 8. The high-pressure water supply mechanism 12 is connected to the rotating shaft 10 to provide high-pressure water flow into the hollow rotating shaft 10. The high-pressure water flow is ultimately ejected from the high-speed rotating high-pressure nozzles 11, forming a powerful water jet. The drainage mechanism rapidly discharges wastewater containing impurities from the housing 1 through a drain pipe 13 connected to the water inlet chamber 2.

[0034] In some embodiments, the drive mechanism 9 includes a motor 22 connected to the rotating shaft 10, providing stable and reliable rotational power to ensure that the high-pressure nozzle 11 can uniformly scan the inner surface of the filter tube 8.

[0035] In some embodiments, the high-pressure water supply mechanism 12 includes a water supply pipe and a high-pressure pump. The water supply pipe is connected to the rotating shaft 10, and the high-pressure pump is connected to the water supply pipe. The high-pressure water supply mechanism 12 provides the high-pressure water source required for cleaning, ensuring that the impact force of the jet of water is sufficient to remove stubborn impurities.

[0036] In some embodiments, the drainage mechanism is a bidirectional pumping device connected to the sewage pipe 13. The bidirectional pumping device is a device that can simultaneously or alternately perform water intake and drainage operations, so that flushing and drainage can be performed after the drainage mechanism is turned on.

[0037] In some implementations, such as Figure 2As shown, the converter 14 includes a sleeve 15, a bearing 16, a seal 17, and a water inlet pipe 18. The sleeve 15 is fixedly mounted on the outside of the housing and sleeved onto the rotating shaft 10. A gap is left between the internal cavity of the sleeve 15 and the outer wall of the rotating shaft 10 to form a water passage cavity 19. The rotating shaft 10 is provided with a water passage hole 20 communicating with its own interior. The sleeve 15 is provided with a water inlet pipe 18 connected to the high-pressure water supply mechanism. The water inlet pipe 18 and the water passage hole 20 are respectively connected to the water passage cavity 19. Bearings 16 for supporting the rotating shaft 10 are fixedly mounted at both axial ends of the sleeve 15. A seal 17 is provided on the side of the bearing 16 facing the water passage cavity 19. The seal 17 can be, for example, an oil seal ring. A limiting protrusion 21 for limiting the sealing 17 is provided on the outer wall of the rotating shaft 10. Thus, the high-pressure water supply mechanism 12 can supply water to the rotating shaft 10 while the motor 22 drives the rotating shaft 10 to rotate.

[0038] In summary, this high-pressure automatic cleaning filter has the following characteristics:

[0039] 1. Integrated filtration and automatic cleaning: By setting up independent inlet chamber 2, outlet chamber 3 and built-in filter tube 8, a high-efficiency filtration channel is constructed; at the same time, the rotating high-pressure jet cleaning mechanism integrated inside the filter tube 8 can automatically remove various impurities that are intercepted.

[0040] 2. Intelligent sensing and automatic triggering capabilities: A pressure sensor installed in the inlet chamber 2 monitors the pressure difference across the filter tube 8 in real time. When the pressure difference reaches a preset threshold, it indicates that the filter screen is severely clogged, and the system can automatically or manually start the cleaning program, realizing an intelligent upgrade from "passive clogging" to "active early warning and cleaning".

[0041] 3. Highly efficient and thorough cleaning without disassembly: The drive mechanism 9 drives the rotating shaft 10 and the high-pressure nozzle 11 to rotate inside the filter tube 8. The high-pressure pump provides a strong water flow. Multiple high-pressure water jets ejected from the nozzle can cover the entire inner wall of the filter tube 8 without dead angles through rotation, which has a strong removal effect on impurities and completely solves the problem of inconvenient cleaning of traditional filters.

[0042] 4. Compact structure and reliable operation: The main functional modules are all integrated into the shell 1, and the external pipeline interface is simple. It is particularly suitable for long-term stable operation in complex environments such as farmland and irrigation pumping stations, which greatly reduces the frequency of maintenance and labor intensity.

[0043] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are within the scope of protection of the claims of the present invention.
