Utility model content
[0005] In view of the above prior art, the technical problem to be solved by the utility model is that when the circulating pump is running, the particulate impurities in the water are easily attached to the filter aperture in the inner wall of the cleaning cylinder. Traditional back cleaning scraping devices, such as simple scrapers and brushes, are difficult to penetrate into the gaps and corners, and the scraping effect is poor, which leads to continuous accumulation of impurities on the inner wall of the cleaning cylinder, reduces the filtering efficiency of the circulating pump, and makes the impurities mixed into the circulating water, affecting the water quality and exacerbating the pipe blockage and equipment wear.
[0006] In order to solve the above problems, the utility model provides a kind of with self-cleaning filter device's circulating pump, including circulating pump body, the inner end of circulating pump body is equipped with hollow filter cartridge, the inner end of circulating pump body is symmetrically provided with multiple groups of cooperation connecting block on upper and lower sides, the end of cooperation connecting block away from circulating pump body is fixedly connected with elastic connecting piece, the end of the upper and lower two elastic connecting pieces away from cooperation connecting block is fixedly connected with vertical stick, the inner end of multiple vertical sticks is all fixedly connected with inner magnetic block, multiple inner magnetic blocks are sequentially annularly distributed from top to bottom between them, the upper end of circulating pump body is fixedly connected with pump cover, the upper inner wall of pump cover is fixedly connected with electric push rod, the output end of electric push rod is fixedly connected with reverse cleaning scraping ring, the outer end lower side of reverse cleaning scraping ring is fixedly connected with main magnetic ring.
[0007] In the above-mentioned circulating pump with self-cleaning filter device, in the auxiliary cleaning, the magnetic force of the main magnetic ring and the inner magnetic block makes the vertical stick hit the outer side wall of the hollow filter cartridge, successfully removes the adherend in the gap, and makes up for the shortage that the traditional cleaning cannot reach the deep impurities.
[0008] As a further improvement of the present application, multiple vertical sticks are annularly and equidistantly distributed outside the hollow filter cartridge, and the main magnetic ring and multiple inner magnetic blocks are sequentially magnetically connected.
[0009] As a further improvement of the present application, the circulating pump body is fixedly connected with multiple support columns, and the multiple support columns are rectangularly distributed.

[0011] As another improvement of the present application, the end of the vertical stick close to the hollow filter cartridge is fixedly connected with a tapered contact vertical bar.
[0012] As a further improvement of the present application, the end of the tapered contact vertical bar close to the hollow filter cartridge is fixedly connected with a rubber contact bar, and the rubber contact bar and the outer side wall of the hollow filter cartridge are in contact with each other.
[0013] In summary, this solution uses a hollow filter cartridge to block impurities in the circulating water with a particle size larger than the filter pore size. During the cleaning process, an electric push rod drives a back-cleaning scraper ring, which, in conjunction with a silicone outer ring, efficiently scrapes off impurities from the inner wall of the hollow filter cartridge. These impurities are then discharged through a discharge valve, achieving initial cleaning of the inner wall and solving the problems of cumbersome traditional manual cleaning operations and disruption of continuous system operation. For auxiliary cleaning, the magnetic force of the main magnetic ring and the inner magnetic block causes the vertical rod to impact the outer wall of the hollow filter cartridge, successfully removing deposits in the crevices and compensating for the inability of traditional cleaning methods to reach deep impurities. At the same time, the rubber contact strip and the conical contact strip can precisely align the impact point while reducing damage to the filter cartridge and extending its service life. Furthermore, the entire self-cleaning process relies solely on the energy of the electric push rod. Through ingenious magnetic and mechanical structures, multiple cleaning functions are achieved without the need for an additional power source, greatly improving energy efficiency and reducing operating costs.

[0023] Two embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0024] The first embodiment is as follows:
[0025] Figures 1-6 A circulating pump with a self-cleaning filter device is shown, comprising a circulating pump body 1, a hollow filter cylinder 5 is installed at the inner end of the circulating pump body 1, a plurality of sets of matching connecting blocks 9 are symmetrically arranged on the upper and lower sides of the inner end of the circulating pump body 1, a resilient connecting piece 10 is fixedly connected to the end of the matching connecting block 9 away from the circulating pump body 1, the end of the upper and lower resilient connecting pieces 10 away from the matching connecting block 9 is fixedly connected with a vertical stand 11, the inner end of the plurality of vertical stands 11 is fixedly connected with an inner magnetic block 13, the plurality of inner magnetic blocks 13 are annularly distributed from top to bottom, the upper end of the circulating pump body 1 is fixedly connected with a pump cover 3, the inner wall of the upper end of the pump cover 3 is fixedly connected with an electric push rod 4, the output end of the electric push rod 4 is fixedly connected with a reverse cleaning scraper ring 6, the outer end of the lower side of the reverse cleaning scraper ring 6 is fixedly connected with a main magnetic ring 8.
[0026] The plurality of vertical stands 11 are annularly and equidistantly distributed outside the hollow filter cylinder 5, the main magnetic ring 8 and the plurality of inner magnetic blocks 13 are sequentially magnetically connected, the circulating pump body 1 is fixedly connected with a plurality of support columns 15, the plurality of support columns 15 are rectangularly distributed, the lower left side of the circulating pump body 1 is fixedly connected with a waste discharge valve pipe 2, the right end of the upper side of the waste discharge valve pipe 2 is fixedly connected with a water inlet valve pipe 16.
[0027] Figures 2-6The hollow filter cylinder 5 is shown in the present scheme, the impurities with particle size larger than the filter aperture of the hollow filter cylinder 5 are blocked outside the hollow filter cylinder 5, and the filtered clean circulating water can continue to flow in the circulating system through the internal passage of the hollow filter cylinder 5, ensuring that the cleanliness of the circulating water meets the system operation requirements and maintaining the normal operation of the circulating system. When the hollow filter cylinder 5 needs to be self-cleaned, the output end of the electric push rod 4 pushes the back cleaning scraper ring 6 to move downward in the hollow filter cylinder 5, the silica gel outer ring 7 fixedly connected to the outer end of the back cleaning scraper ring 6 is in close contact with the inner side wall of the hollow filter cylinder 5, and as the back cleaning scraper ring 6 moves downward, the silica gel outer ring 7 can scrape off the impurities attached to the inner wall of the hollow filter cylinder 5. The scraped impurities settle at the bottom of the circulating pump body 1 under the action of gravity and are discharged from the circulating pump body 1 through the discharge valve pipe 2 fixedly connected to the left side of the lower end of the circulating pump body 1, thereby realizing the preliminary cleaning of the inner wall of the hollow filter cylinder 5. The main magnetic ring 8 fixedly connected to the outer end of the back cleaning scraper ring 6 plays a key role in the process of moving downward, the main magnetic ring 8 generates an attractive magnetic force with the inner magnetic blocks 13 distributed in the multiple vertical rods 11 outside the hollow filter cylinder 5. Since the vertical rods 11 are connected with the matching blocks 9 through the elastic connecting pieces 10, the elastic connecting pieces 10 are stretched under the action of the magnetic force, and the multiple vertical rods 11 are sequentially hit with the outer side wall area of the hollow filter cylinder 5 under the combined action of the elastic restoring force of the elastic connecting pieces 10 and the magnetic force. This impact can help to pop out the attachments in the crevices of the hollow filter cylinder 5 in the opposite direction, effectively solving the problem that the traditional cleaning method is difficult to remove the impurities in the crevices. The present self-cleaning process only uses the driving energy of the electric push rod 4, realizes multiple cleaning functions through magnetic force and mechanical structure design, does not need additional energy consumption, greatly improves the energy utilization efficiency, reduces the operation cost, and effectively distinguishes from the complex cleaning method relying on multiple power sources in the prior art.
