At the same time, the filter screen assembly 2 is installed in the connecting seat 12 at the lower end of the main housing 11, ensuring that the filter screen assembly 2 can be fixedly installed in the lower end of the connecting seat 12 with bolts for stable filtration. At the same time, a sealing cover 3 is installed on the lower end face of the filter screen assembly 2, which can easily block the lower end face of the filter screen assembly 2. This ensures that liquid entering the filter screen assembly 2 can only pass through the filter screen assembly 2 and be discharged. Moreover, the sealing cover 3 and the filter screen assembly 2 are connected by threads, which is easy to assemble and disassemble quickly. When the filter screen assembly 2 needs to be cleaned, the sealing cover 3 can be removed to easily clean the impurities without disassembling the filter. At the same time, a cleaning disc assembly 4 is set directly below the main housing 11. When in use, the cleaning disc assembly 4 can move up and down under the drive of the drive component 5, thereby cleaning the inner surface of the filter screen assembly 2 through the cleaning disc assembly 4.

[0027] Reference Figure 1 and Figure 2As shown, an inlet pipe head 111 is symmetrically installed on the upper end face of the main housing 11. The inlet pipe head 111 is integrally formed with the main housing 11. A guide rod 112 is also fixedly installed on the lower end face of the main housing 11. By symmetrically installing two sets of inlet pipe heads 111 on the upper end face of the main housing 11, it is easy to connect to an external liquid pipe through the inlet pipe head 111. This ensures that the liquid to be treated can stably enter the instrument head 1 from the inlet pipe head 111 and then flow into the filter screen group 2 for filtration. At the same time, by fixing the guide rod 112 on the lower end face of the main housing 11, it ensures better installation of the cleaning disc group 4 and facilitates stable lifting and lowering adjustment of the cleaning disc group 4. The connecting seat 12 includes a ring seat 121 and a top flange 122. The ring seat 121 is fixedly installed on the lower end face of the main housing 11, and the top flange 122 is coaxially fixed on the lower end face of the ring seat 121. By designing the connecting seat 12 into a structure in which the ring seat 121 and the top flange 122 cooperate, it can be fixed to the lower end face of the main housing 11 through the ring seat 121 when it is easy to use. This makes it easy to clean the disc assembly 4 and store it in the ring seat 121 when not in use. At the same time, by fixing the top flange 122 to the lower end of the ring seat 121, it is easy to install the filter assembly 2 through the top flange 122.

[0028] Reference Figure 1 and Figure 3 As shown, the filter assembly 2 includes a filter ring 21 and a bottom flange 22. The bottom flange 22 is fixedly installed on the upper end face of the filter ring 21, and is fixedly connected to the top flange 122 by bolts. By designing the filter assembly 2 into a structure where the filter ring 21 and the bottom flange 22 mate, the filter ring 21 can be connected to the top flange 122 via the bottom flange 22 for easy use. Furthermore, to ensure a tighter connection, a sealing ring can be installed between the bottom flange 22 and the top flange 122.

[0029] Reference Figure 1 and Figure 4 As shown, the sealing cover 3 includes a bottom cover 31 and an internal threaded ring 32. The internal threaded ring 32 is disposed on the upper end face of the bottom cover 31 and is integrally formed with the bottom cover 31. The lower end of the filter ring 21 is provided with an external thread that mates with the internal threaded ring 32. By designing the sealing cover 3 into a structure in which the bottom cover 31 and the internal threaded ring 32 mate, the bottom cover 31 can be installed on the lower end of the filter ring 21 via the internal threaded ring 32 when in use, thus covering the bottom of the filter ring 21. The sealing cover 3 and the filter ring 21 are connected by threads, allowing for easy disassembly and assembly when in use.

[0030] Reference Figure 5 and Figure 6As shown, the cleaning disc assembly 4 includes a top frame 41 and a side scraper ring 42. The side scraper ring 42 is located on the lower end face of the top frame 41 and is integrally formed with the top frame 41. A chamfer 421 is provided on the inner side of the lower end face of the side scraper ring 42. By designing the cleaning disc assembly 4 into a structure in which the top frame 41 and the side scraper ring 42 cooperate, it is convenient to drive the side scraper ring 42 to move up and down synchronously during use through the top frame 41. At the same time, by providing a chamfer 421 on the inner side of the lower end face of the side scraper ring 42, it is ensured that the side scraper ring 42 can better clean the impurities on the inner side of the filter ring 21 through the beveled surface of the chamfer during the downward movement. The top frame 41 includes a ring plate 411, a middle plate 412, and a threaded sleeve 413. The middle plate 412 is fixedly installed in the middle of the ring plate 411, and the threaded sleeve 413 is fixedly installed at the center of the upper end face of the middle plate 412. A positioning hole 414 is provided on the middle plate 412 to cooperate with the guide rod 112. By designing the top frame 41 into a structure in which the ring plate 411, the middle plate 412, and the threaded sleeve 413 cooperate, the threaded sleeve 413 can be installed through the middle plate 412 in the middle of the ring plate 411 when it is easy to use. When it is convenient to use, the threaded sleeve 413 can be connected to the drive component 5. At the same time, by opening a positioning hole 414 on the middle plate 412, it can be conveniently and stably fitted onto the guide vertical rod 112, ensuring that the top frame 41 can only be adjusted by lifting and sliding during use, and there will be no rotation operation.

[0031] Reference Figure 1 and Figure 2As shown, the driving component 5 includes a drive motor 51 and a threaded rod 52 that mates with the threaded sleeve 413. The drive motor 51 is fixedly installed in the main housing 11, and the threaded rod 52 is installed at the lower end of the main housing 11, with its head connected to the output end of the drive motor 51. By designing the driving component 5 with the drive motor 51 and the threaded rod 52 mate, it is convenient to use the drive motor 51 to drive the threaded rod 52 to rotate, thereby achieving the purpose of driving the threaded sleeve 413 to rise and fall through the engagement of the threaded rod 52 and the threaded sleeve 413. A positioning groove 113 for installing the drive motor 51 is provided at the center of the upper end face of the main housing 11, and a removable sealing plug 114 is installed in the positioning groove 113. By providing a positioning groove 113 at the center of the upper end face of the main housing 11, it is convenient to install the drive motor 51 through the positioning groove 113, and the sealing plug 114 seals the positioning groove 113, ensuring the safety of the drive motor 51 during use. A positioning sleeve 311 for inserting the bottom of the threaded rod 52 is provided at the center of the upper end face of the bottom cover 31, and a double ring frame 312 for mounting the guide vertical rod 112 is also provided on the upper end face of the bottom cover 31. The positioning sleeve 311, the double ring frame 312 and the bottom cover 31 are integrally formed. By providing the positioning sleeve 311 and the double ring frame 312 on the upper end face of the bottom cover 31, it can be ensured that the bottom of the threaded rod 52 is inserted into the positioning sleeve 311 after the bottom cover 31 is installed at the lower end of the filter ring 21, and the lower end of the guide vertical rod 112 can be inserted into the double ring frame 312, thereby ensuring that the threaded rod 52 and the guide vertical rod 112 are used more stably.

[0032] Working principle: In actual filtration use, the filter is fixedly installed inside the equipment through the instrument head 1, and then connected to the equipment's drain pipe through the liquid inlet head 111. During normal use, liquid can flow steadily into the filter screen group 2 from the liquid inlet head 111 and be discharged through the side of the filter screen ring 21 of the filter screen group 2. The filtered impurities will remain on the inner side of the filter screen ring 21. When cleaning is required, the drive motor 51 is started to drive the threaded rod 52 to rotate. Through the threaded engagement between the threaded rod 52 and the threaded sleeve 413, the cleaning disc group 4 is stably moved from the ring seat 121 into the filter screen ring 21, thereby cleaning the impurities on the inner side of the filter screen ring 21. The impurities can fall steadily onto the sealing cover 3 at the lower end of the filter screen ring 21. After cleaning, the impurities can be removed by disassembling the sealing cover 3. The filter screen group 2 can be cleaned flexibly without disassembling it.
