[0003] For example, the utility model with announcement number CN212166672U discloses a filter-type automatic sand removal device. In order to improve the automatic sand removal capability of the sand removal device, a transmission main shaft is provided through the inner side of the mechanical seal, a sewage scraper is fixed on the outer side of the transmission main shaft, a filter cartridge is fixed on the inner side of the filter tank body, a pressure sensor is fixed on the inner wall of the filter tank body at the bottom, and the filter tank body is connected to the sewage tank through a sewage outlet. The utility model drives the sewage scraper to scrape the impurities of the filter cartridge in a cyclic manner through a transmission motor, which can not only efficiently clean the impurities adhered to the inner wall of the filter cartridge, but also ensure that the impurities are removed without stopping the water supply. The uniform storage of impurity sewage in the sewage tank can facilitate the staff to uniformly discharge the impurity sewage and avoid the staff from frequently processing the cleaned impurity sewage.

[0004] In the process of implementing this application, it was found that the technology has the following problems: the switch of the internal control motor of the existing filter-type automatic sand and desander is mostly set at the outer end of the filter cartridge during use, so that when blockage occurs inside the filter cartridge later, the water flow cannot enter the interior of the sewage tank, resulting in the switch of the control motor cannot be triggered during use, thereby reducing the practicality of the device.

[0005] For this reason, a filter screen type automatic sand removal and desanding device is proposed. Utility Model Content

[0028] like Figures 1 to 4 As shown, the cleaning mechanism 4 includes a fixed rod 402, which is mounted on the lower surface of the output shaft of the motor 103, a fixed plate 401 is mounted on the lower surface of the fixed rod 402, and two groups of scrapers 403 are arranged on the upper surface of the fixed plate 401, and the opposite sides of the two groups of scrapers 403 are attached to the left and right sides of the filter tank 104, and the adjacent sides of the two groups of scrapers 403 are provided with grooves;

[0029] The driving mechanism 5 includes a slide plate 501 and a contact switch 502. The slide plate 501 is slidably connected to the inside of the grooves of the two groups of scrapers 403. The contact switch 502 is installed on the top of the inner wall of the groove of the right group of scrapers 403. The contact switch 502 is located on the moving path of the slide plate 501. The contact switch 502 is electrically connected to the control end of the motor 103. Specifically, the fixed rod 402 and the two groups of scrapers 403 are driven to rotate by starting the motor 103, and then the opposite sides of the two groups of scrapers 403 are attached to the inner wall of the filter tank 104, so that the two groups of scrapers 403 can scrape off the mud and sand accumulated on the inner wall of the filter tank 104 during the rotation, thereby avoiding the blockage of the subsequent filter tank 104 during use.

[0030] At the same time, when the filter holes on the inner wall of the filter tank 104 are blocked, the water level inside the filter tank 104 drives the slide plate 501 to float upward, so that the slide plate 501 slides upward along the grooves of the two groups of scrapers 403, and then the contact switch 502 is located on the moving path of the slide plate 501, so that the contact switch 502 is triggered to start the motor 103 during the process of the slide plate 501 sliding upward, so that the staff does not need to turn on the motor 103 for a long time when using the device to filter sewage, thereby reducing the subsequent power consumption of the device during use, thereby improving the practicality of the device; the drive mechanism 5 is arranged inside the filter tank 104, so that the drive mechanism 5 can quickly trigger and start the motor 103 during use, thereby trying to avoid the subsequent sewage overflowing from the interior of the filter tank 104 and entering the interior of the treatment tank 101, which leads to a decrease in the sewage treatment effect of the device;

[0032] like Figure 4 As shown, a group of scrapers 403 near the contact switch 502 are provided with 7 at the top of the inner wall of the groove, and the position of 7 is set between the positioning rod 601 and the contact switch 502; specifically, by setting the position of 7 between the positioning rod 601 and the contact switch 502, the contact switch 502 blocks the splashing sewage and adheres to the outer surface of the contact switch 502, thereby avoiding the contact switch 502 from being in contact with the sewage for a long time during use, thereby preventing the contact switch 502 from being damaged, thereby improving the service life of the driving mechanism 5.

[0033] like Figure 4 As shown, the contact switch 502 includes a switch and a shell, and the height of the lower surface 7 is kept parallel to the lower surface of the contact switch 502 shell; specifically, by keeping the height of the lower surface 7 parallel to the lower surface of the contact switch 502 shell, the position of the sliding plate 501 in the moving path inside the grooves of the two groups of scrapers 403 is restricted by 7, thereby minimizing the excessive squeezing of the contact switch 502 by the sliding plate 501 during subsequent use.
