Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] See also Figure 1-3 , an automatic cleaning device for a filter tank in a water plant comprises an external cleaning rack 1, wherein a plurality of internal cleaning racks 2 for cleaning filter tanks are arranged between the rack bodies of the external cleaning rack 1.

[0024] The external cleaning frame 1 includes an upper frame 101, a driving connecting plate 1012 is fixedly connected to the middle position of the left and right sides of the upper frame 101, a lower scraper 1011 is fixedly connected to the ground along the frame path of the upper frame 101, the lower part of the upper frame 101 is fixedly connected to the lower frame 102 through a plurality of support rods, and an upper scraper 1021 is fixedly connected to the upper surface of the lower frame 102 along the path, and the cross-sections of the lower scraper 1011 and the upper scraper 1021 are right-angled triangles. The two frames are angular in shape and have the same structural arrangement. A plurality of inner frames 103 are fixedly connected to the corresponding filter tanks between the upper frame 101 and the lower frame 102. The bottom surface of the upper frame of the inner frame 103 and the upper surface of the lower frame are also fixedly connected to the lower scraper plate 1011 and the driving connecting plate 1012. The upper surface of the inner frame 103 is fixedly connected to the water guide plate 104. The water guide plate 104 is a C-shaped ridge plate with an inclined upper surface, and a relatively lower side is arranged to point to the upper frame 101.

[0025] The internal cleaning frame 2 comprises an internal frame 201 , the upper frame of the internal frame 201 is fixedly connected to the inner flange of the water guide plate 104 , and the bottom surface of the upper frame of the internal frame 201 and the upper surface of the lower frame are fixedly connected with an internal scraper 2011 .

[0026] When working, first place the external cleaning frame 1 and the internal cleaning frame 2 into the filter tank along the inner wall of the filter tank, then set two hydraulic jacks at the position of the driving connecting plate 1012, then connect the hydraulic jacks to the driving connecting plate 1012, and bind the hydraulic jacks to the recoil system, and then it can be used; when the recoil system of the filter tank is working, the recoil system will flush out the sludge mixed in the sand and gravel in the filter tank by first air flushing and then air flushing and water flushing, and the sludge will be separated and filtered by the internal cleaning frame 2 and then overflow upwards. When performing air flushing and water flushing, the hydraulic jack will push up the upper frame 101, so that it drives the lower frame 102, the inner frame 103 and the inner frame 201 along the filter The inner wall of the pool moves upward, and during the upward movement, the lower frame 102, the inner frame 103 and the internal frame 201 will scrape and clean the dirt attached to the inner wall through the upper scraper 1021 and the internal scraper 2011 fixed on the frame surface, and the hanging sludge will fall into the waterway and filter tank of the filter tank and be washed away by the backwash sewage. At the end of the backwash, the hydraulic top will pull back the upper frame 101, reset the external cleaning frame 1 and the internal cleaning frame 2, and then the water that needs to be cleaned and filtered will be refilled into the waterway of the filter tank, and then enter the filter tank for filtration after being guided by the water guide plate 104, so as to assist the backwash cleaning system to complete the comprehensive cleaning of the filter tank.

[0027] To sum up, through the setting of the external cleaning frame 1 and the internal cleaning frame 2, it can cooperate with the backwash cleaning system and the hydraulic top controlled therewith, and during air flushing and water flushing, it can automatically perform comprehensive scraping and cleaning of the filter trough and the inner wall of the filter tank, and cooperate with the flushing effect to clean the scraped inner wall.

Example 2

[0028] See also Figure 1-4 This embodiment provides a technical solution based on the first embodiment: a sand-fixing plate 2012 is fixedly connected to the upper inner side of the lower frame of the internal frame 201, a prism-shaped through hole is opened on the surface of the sand-fixing plate 2012, and the large hole is at the bottom and the small hole is at the top, and a sand-covering net 2013 is fixedly connected to the upper surface of the sand-fixing plate 2012.

[0029] When working, the backwash cleaning system of the filter tank will first perform air flushing on the filtered sand and gravel to flush out the sludge in the sand and gravel, and the flushed sludge will pass through the separation filtration of the sand fixing plate 2012 and the sand covering net 2013 and enter the top of the sand covering net 2013. After performing air flushing for a certain period of time, water flushing will be performed at the same time, and the cleaning water will carry the sludge from the filter tank to the waterway on the surrounding side, and then be discharged through the waterway.

[0030] In summary, by setting up the internal frame 201, the sand fixing plate 2012 and the sand covering net 2013, the sand and gravel in the filter tank can be blocked, filtered and covered when the air flushing is performed, so as to prevent the sand and gravel from being carried away by the sludge under the action of the air flushing, thereby reducing the loss of filtered sand and gravel due to cleaning loss.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Working principle: when working, first place the external cleaning frame 1 and the internal cleaning frame 2 into the filter tank along the inner wall of the filter tank, then set two hydraulic jacks at the position of the driving connecting plate 1012, then connect the hydraulic jacks to the driving connecting plate 1012, and bind the hydraulic jacks to the backwash system, and then it can be used; when the backwash cleaning system of the filter tank is working, it will first perform air flushing on the filtered sand and gravel to flush out the sludge in the sand and gravel, and the flushed sludge will pass through the separation filtration of the sand fixing plate 2012 and the sand covering net 2013 and enter the top of the sand covering net 2013. After executing the air flushing for a certain period of time, the water flushing will be performed at the same time. When executing the air flushing and water flushing, the hydraulic jack will push up the upper frame 101, so that it drives the lower frame 10 2. The inner frame 103 and the inner frame 201 move upward along the inner wall of the filter tank. During the upward movement, the lower frame 102, the inner frame 103 and the inner frame 201 will scrape and clean the dirt attached to the inner wall through the upper scraper 1021 and the internal scraper 2011 fixed on the frame surface, and the hanging sludge will fall into the waterway and filter tank of the filter tank and be washed away by the backwash sewage. At the end of the backwash, the hydraulic top will pull back the upper frame 101 to reset the external cleaning frame 1 and the internal cleaning frame 2, and then the water that needs to be cleaned and filtered will be refilled into the waterway of the filter tank, and then enter the filter tank for filtration after being guided by the water guide plate 104, thereby assisting the backwash cleaning system to complete the comprehensive cleaning of the filter tank.
