[0002] Shallow - layer medium filtration is to filter impurities in water quality to achieve the purpose of reducing impurities in water. Currently, shallow - layer medium filtration generally involves passing water into a filtration tank, and using a filter screen in the filtration tank to intercept and filter impurities in the water, thereby achieving the purpose of shallow - layer medium filtration.

[0003] The Chinese patent discloses a fully - automatic shallow - layer medium filtration system (publication number CN208525916U). In this patented technology, the water supply pipe conveys water to the water inlet, and the water is evenly sprayed onto the filter layer through a water distributor. The filter layer filters the water, and finally it is conveyed out through a water collector. The dirt in the filter layer is cleaned through the water discharge pipe, which makes the filtration effect better. At the same time, it is convenient to clean the inside of the tank body, with convenient operation, time - saving, high safety, and improved filtration work efficiency.

[0004] However, there are still deficiencies in view of this patent. Although this patent can wash the filter screen, as can be seen from the drawings of this patent, when this patent is in use, the filter screen cannot be taken out from the inside of the tank body, which makes it impossible to replace and maintain the filter screen. In this way, when the filter screen is damaged after long - term use, the shallow - layer medium filtration work cannot be carried out. Therefore, those skilled in the art have provided a fully - automatic shallow - layer medium filtration device to solve the problems raised in the above - mentioned background technique. Content of the Utility Model

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a fully automatic shallow - layer medium filtration device includes a filter box 1, a door 3 of the box clamped on the front surface of the filter box 1, a water distribution pipe 11 penetrating through the upper surface of the filter box 1. A filter screen 12 is arranged inside the filter box 1, and a recycling box 4 is installed on one side of the filter box 1, and a cleaning motor 2 is installed on the other side of the filter box 1. A screw rod 22 is arranged above the filter screen 12 at the driving end of the cleaning motor 2, and a cleaning plate 23 is arranged above the filter screen 12 outside the screw rod 22. Positioning plates 32 are symmetrically arranged on the rear surface of the door 3 of the box, and a positioning groove 13 is opened on the front surface of the filter box 1. Fixed rods 5 are arranged on both the upper surface and the lower surface of the filter box 1. A limit rod 51 penetrates through the upper end of the fixed rod 5 at the position of the lower surface of the filter box 1. This setting utilizes the quick installation and disassembly of the door 3 of the box and the filter box 1, so as to facilitate the replacement and maintenance of the filter screen 12 inside the filter box 1, and the impurities on the filter screen 12 can be cleaned by moving the cleaning plate 23 on the filter screen 12.

[0023] In Figure 2 and Figure 3 : A bearing 221 is arranged inside the recycling box 4, and one end of the screw rod 22 is embedded inside the bearing 221 and rotatably connected to the bearing 221. Guide rods 21 are arranged in front of and behind the screw rod 22 inside the filter box 1. The cleaning plate 23 is slidably arranged outside the guide rod 21 and the screw rod 22. This setting utilizes the rotation of the screw rod 22 caused by the operation of the cleaning motor 2, and makes the cleaning plate 23 move outside the screw rod 22 and the guide rod 21 to achieve the purpose of cleaning the upper surface of the filter screen 12.

[0024] In Figure 3In the middle: The lower surface of the cleaning plate 23 contacts the upper surface of the filter screen 12. A discharge groove is provided inside the filter box 1. The upper surface of the filter screen 12 is flush with the lower surface of the discharge groove. This setting makes it convenient to scrape impurities into the interior of the recycling box 4 for recycling by making the filter screen 12 flush with the discharge groove.

[0025] In Figure 4 In the middle: The rear surface of the positioning plate 32 is embedded in the interior of the positioning groove 13. A sealing gasket 31 is further provided on the rear surface of the box door 3. The rear surface of the sealing gasket 31 contacts the front surface of the filter box 1. This setting can improve the sealing performance of the connection between the filter box 1 and the box door 3 by using the sealing gasket 31.

[0026] In Figure 4 In the middle: A limiting hole is provided outside the positioning plate 32. The lower end of the limiting rod 51 is embedded in the interior of the limiting hole. An electric telescopic rod 52 is further provided inside the fixing rod 5. The telescopic end of the electric telescopic rod 52 is connected to the upper end of the limiting rod 51. This setting can fix the positioning plate 32 by making the limiting rod 51 embed into the limiting hole when the electric telescopic rod 52 works.

[0027] The working principle of the present utility model is as follows: When the fully automatic shallow - layer medium filtration device of the present utility model is in use, shallow - layer medium can be introduced into the interior of the filter box 1 through the water distribution pipe 11 for filtration treatment. After entering, it is filtered through the filter screen 12. After filtration, by starting the cleaning motor 2 to work, the screw rod 22 rotates inside the filter box 1. When rotating, the cleaning plate 23 moves outside the screw rod 22 and the guide rod 21. Furthermore, large impurities on the filter screen 12 can be scraped by the cleaning plate 23, so as to scrape and clean the impurities into the interior of the recycling box 4. Small impurities can be processed through backwashing. When it is necessary to replace and maintain the filter screen 12 inside the filter box 1, at this time, by starting the electric telescopic rod 52 inside the fixing rod 5 to work, the limiting rod 51 will enter the interior of the fixing rod 5, and the positioning plate 32 will be pulled out from the positioning groove 13, thus achieving the purpose of quickly separating the box door 3 from the filter box 1 for the purpose of disassembling and maintaining the filter screen 12.

[0028] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
