Technical Field

[0001] This application relates to the technical field of filters, and in particular to a filter that is easy to clean. Background Technology

[0002] Filters are indispensable devices in pipelines transporting media. They are typically installed at the inlet end of pressure reducing valves, pressure relief valves, and level control valves, facilitating the filtration of other equipment. A filter consists of a cylinder, a stainless steel filter screen, a drain section, a transmission device, and an electrical control system. When water to be treated passes through the filter cylinder, impurities are blocked. Cleaning is simple; just remove the removable filter cylinder, clean it, and reinstall it. Therefore, use and maintenance are extremely convenient. However, after prolonged use, existing filters accumulate a large amount of impurities on the filter screen surface, affecting filtration efficiency.

[0003] Regarding the aforementioned technologies, it has been found that traditional cleaning methods typically require complete disassembly of the filter, which is cumbersome and may damage the filter during the cleaning process. Furthermore, some filter screens are not thoroughly cleaned, leading to reduced filtration efficiency upon reuse. Therefore, it is necessary to design a filter that is easy to clean to improve cleaning efficiency and extend its service life. Utility Model Content

[0004] To achieve efficient and rapid cleaning of the filter, this application provides a filter that is easy to clean.

[0005] The filter provided in this application, which is easy to clean, adopts the following technical solution:

[0006] A filter that is easy to clean includes a filter body, which includes a housing and a cover. The cover is fastened to the upper end face of the housing and is sealed and fixedly connected to the housing. A positioning frame is installed in the housing and is fixedly connected to the housing. A filter screen assembly is installed in the positioning frame and is rotatably connected to the positioning frame. A current-collecting shell is also installed above the positioning frame and is fixedly connected to the positioning frame. A drive rod assembly for driving the filter screen assembly to rotate is also rotatably installed on the housing. A guide seat is also fixedly installed on the outer side of the housing. A locking rod is slidably installed on the guide seat, and a support spring for supporting the locking rod is also fixedly installed on the guide seat.

[0007] By adopting the above technical solution, the filter body uses a combination structure of a shell and a cover, which facilitates disassembly and installation, and makes it convenient to maintain and clean the inside of the filter. The positioning frame provides a stable installation position for the filter mesh assembly, ensuring its stability inside the filter. The rotatable connection between the filter mesh assembly and the positioning frame allows for easier rinsing of impurities on the filter surface during cleaning, improving the cleaning effect. The converging shell gathers and guides the liquid entering the filter, allowing it to pass through the filter mesh assembly more evenly and improving filtration efficiency. The drive rod assembly allows operators to manually drive the filter mesh assembly, making operation simple and convenient.

[0008] Optionally, a liquid outlet pipe is fixedly installed on the lower end face of the outer shell, and a liquid inlet pipe and a flushing pipe are installed on the upper end face of the cover. Both the liquid inlet pipe and the flushing pipe are sealed and fixedly connected to the cover.

[0009] By adopting the above technical solution, the liquid outlet pipe on the lower end face of the housing is used to discharge the filtered liquid, the liquid inlet pipe on the upper end face of the cap is used to input the liquid to be filtered, and the flushing pipe is used to input cleaning fluid when cleaning the filter. The liquid inlet pipe and the flushing pipe are sealed and fixedly connected to the cap, ensuring that no leakage occurs during the liquid input process, thus improving the sealing performance and reliability of the filter.

[0010] Optionally, the positioning frame includes a circumferential seat and a support rod for supporting the flow-gathering shell. The support rod is evenly installed on the upper surface of the circumferential seat and is fixedly connected to the circumferential seat.

[0011] By adopting the above technical solution, the circumferential seat of the positioning frame provides a ring-shaped support structure for the filter assembly, enabling the filter assembly to be stably installed within it. The even distribution of the support rods provides stable support for the flow-gathering shell, ensuring that the flow-gathering shell is fixed in position inside the filter, and guaranteeing the flow-gathering and guiding effect of the liquid.

[0012] Optionally, the filter assembly includes an inner frame and a filter plate, wherein the filter plate is installed in the inner frame and the edge of the filter plate is fixedly connected to the inner frame.

[0013] By adopting the above technical solution, the inner mesh frame of the filter assembly provides an installation frame for the filter plate, allowing the filter plate to be firmly installed in the inner mesh frame. The filter plate is used to filter impurities in the liquid, and its edges are fixedly connected to the inner mesh frame to prevent the filter plate from shifting or deforming during use, ensuring the stability of the filtration effect.

[0014] Optionally, two sets of connecting seats are symmetrically installed on the outer side of the inner mesh frame. The connecting seats are integrally formed with the inner mesh frame, and the connecting seats are provided with connecting holes.

[0015] By adopting the above technical solution, the connecting seat on the outer side of the inner mesh frame is integrally formed with the inner mesh frame, ensuring the connection strength between the connecting seat and the inner mesh frame. The connecting hole on the connecting seat is used to cooperate with the plug-in rotating rod of the drive rod assembly to realize the connection between the drive rod assembly and the filter mesh assembly, so that the drive rod assembly can accurately drive the filter mesh assembly to rotate.

[0016] Optionally, the flow-gathering shell includes an annular top frame and a flow-guiding shell, wherein the flow-guiding shell is installed on the lower end face of the annular top frame and is fixedly connected to the annular top frame.

[0017] By adopting the above technical solution, the annular top frame of the flow-collecting shell provides an installation base for the flow-guiding shell. The installation of the flow-guiding shell can guide the liquid entering the filter, allowing the liquid to flow downwards along the shape of the flow-guiding shell and pass through the filter screen more evenly. This avoids situations where the liquid flows too fast or too slow in certain areas inside the filter, thereby improving filtration efficiency.

[0018] Optionally, the lower end face of the annular top frame is provided with a plurality of sleeves connected to the support rods along the circumferential direction, and the sleeves are fixedly connected to the annular top frame.

[0019] By adopting the above technical solution, the sleeve on the lower end face of the annular top frame is connected to the support rod, allowing the flow-gathering shell to be firmly installed on the positioning frame. The fixed connection between the sleeve and the annular top frame ensures the stability of the connection between the flow-gathering shell and the positioning frame, preventing the flow-gathering shell from shaking or shifting during use, which would affect the flow-gathering and guiding effect of the liquid.

[0020] Optionally, the drive rod assembly includes a plug-in rotating rod and an operating panel. One end of the plug-in rotating rod is plugged into and fixed in a connecting hole, and the operating panel is fixedly installed on the outer end of the plug-in rotating rod. Two sets of slots that cooperate with the locking rod are symmetrically opened on the outer side of the operating panel.

[0021] By adopting the above technical solution, one end of the drive rod assembly's plug-in rotating rod is inserted and fixed in the connecting socket, achieving a reliable connection between the drive rod assembly and the filter assembly. The operating panel is fixedly installed on the outer end of the plug-in rotating rod, allowing operators to manually rotate the operating panel to drive the filter assembly to rotate. The operation is simple and convenient, requiring no complicated tools or equipment. The two sets of slots ensure that the filter assembly can be used stably in both forward and reverse directions.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The filter of this application, by setting a drive rod assembly, allows manual rotation of the filter screen assembly. During cleaning, simply rotating the operating disc makes it easier to wash away impurities on the filter screen surface, eliminating the need for complete filter disassembly, greatly improving cleaning efficiency and reducing cleaning time and workload. The converging shell design gathers and guides the liquid entering the filter, allowing the liquid to pass through the filter screen assembly more evenly, avoiding localized excessively fast or slow flow of liquid inside the filter, thus improving filtration efficiency and ensuring the stability of the filtration effect. The rational design and installation of components such as the positioning frame and converging shell provide stable support and connection for the various components inside the filter, ensuring the stability and reliability of the filter during use and reducing malfunctions caused by loose or displaced components.

The rotatable connection between the filter screen assembly 3 and the positioning frame 2 allows the filter screen assembly 3 to be rotated during cleaning, making it easier to wash away impurities on the filter screen surface and improving the cleaning effect. The installation of the flow-gathering shell 4 can gather and guide the liquid entering the filter, allowing the liquid to pass through the filter screen assembly 3 more evenly and improving filtration efficiency. The drive rod assembly 5 allows the operator to manually drive the filter screen assembly 3 to rotate, making operation simple and convenient. The outlet pipe 111 is fixedly installed on the lower end face of the outer shell 11, and the inlet pipe 121 and flushing pipe 122 are installed on the upper end face of the cover 12. Both the inlet pipe 121 and the flushing pipe 122 are sealed and fixedly connected to the cover 12. The outlet pipe 111 on the lower end face of the outer shell 11 is used to discharge the filtered liquid, the inlet pipe 121 on the upper end face of the cover 12 is used to input the liquid to be filtered, and the flushing pipe 122 is used to input the cleaning fluid when cleaning the filter. The sealed and fixed connection between the inlet pipe 121 and the flushing pipe 122 and the cover 12 ensures that no leakage occurs during the liquid input process, improving the sealing performance and reliability of the filter.

[0031] Reference Figure 3 As shown, the positioning frame 2 includes an circumferential seat 21 and support rods 22 supporting the flow-gathering shell 4. The support rods 22 are evenly installed on the upper surface of the circumferential seat 21 and are fixedly connected to the circumferential seat 21. The circumferential seat 21 of the positioning frame 2 provides an annular support structure for the filter assembly 3, allowing the filter assembly 3 to be stably installed therein. The even distribution of the support rods 22 provides stable support for the flow-gathering shell 4, ensuring that the position of the flow-gathering shell 4 is fixed inside the filter, thus guaranteeing the flow-gathering and guiding effect of the liquid.

Its edge is fixedly connected to the inner frame 31 to prevent displacement or deformation during use, ensuring the stability of the filtration effect. Two sets of connecting seats 311 are symmetrically installed on the outer surface of the inner frame 31. The connecting seats 311 are integrally formed with the inner frame 31, and the connecting seats 311 have connecting holes 312. The connecting seats 311 on the outer side of the inner frame 31 are integrally formed with the inner frame 31, ensuring the connection strength between the connecting seats 311 and the inner frame 31. The connecting hole 312 on the connecting seat 311 is used to cooperate with the plug-in rotating rod 51 of the drive rod assembly 5 to realize the connection between the drive rod assembly 5 and the filter screen assembly 3, so that the drive rod assembly 5 can accurately drive the filter screen assembly 3 to rotate.

[0033] Reference Figure 3 and Figure 5 As shown, the flow-concentrating shell 4 includes an annular top frame 41 and a flow-guiding shell 42. The flow-guiding shell 42 is installed on the lower end face of the annular top frame 41 and is fixedly connected to the annular top frame 41. The annular top frame 41 of the flow-concentrating shell 4 provides an installation base for the flow-guiding shell 42. The installation of the flow-guiding shell 42 can guide the liquid entering the filter, allowing the liquid to flow downward along the shape of the flow-guiding shell 42, and pass through the filter screen group 3 more evenly, avoiding local flow that is too fast or too slow inside the filter, thus improving filtration efficiency.

The operating disc 52 is fixedly installed on the outer end of the plug-in rotating rod 51, allowing the operator to manually rotate the operating disc 52, thereby driving the filter assembly 3 to rotate. The operation is simple and convenient, requiring no complex tools or equipment. A guide seat 6 is also fixedly installed on the outer surface of the outer casing 11. A locking rod 61 is slidably installed on the guide seat 6, and a support spring 62 supporting the locking rod 61 is also fixedly installed on the guide seat 6. Two sets of slots 521 that cooperate with the locking rod 61 are symmetrically opened on the outer surface of the operating disc 52. The guide seat 6 and the support spring 62 are designed to ensure that the locking rod 61 can be stably inserted into the slot 521 to lock the operation panel 52. In this way, the two sets of slots 521 ensure that the filter group 3 can be used stably in both forward and reverse states.

[0035] The implementation principle of an easy-to-clean filter according to an embodiment of this application is as follows: In actual use, the liquid to be filtered is input into the filter through the inlet pipe 121. After being collected and guided by the flow-gathering shell 4, the liquid passes evenly through the filter screen assembly 3. Impurities are intercepted by the filter screen plate 32, and the filtered liquid is discharged through the outlet pipe 111. When the filter needs to be cleaned, the inlet pipe 121 is closed, and cleaning fluid is introduced through the flushing pipe 122. The operator manually rotates the operating panel 52, causing the filter screen assembly 3 to rotate, making it easier for impurities on the surface of the filter screen to fall off under the flushing and rotation of the cleaning fluid. The cleaned wastewater is discharged through the outlet pipe 111.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
