An upper cover 6 is provided at the upper opening of the sand filter tank 5, and the side wall of the upper cover 6 is detachably connected to the sand filter tank 5 through a plurality of bolt connectors 3.

[0028] A backwash controller 11 is fixedly installed in the middle of the side wall of the equipment box 1. An inlet cylinder pipe 15 and an outlet cylinder pipe 16 are connected to the backwash controller 11. The ends of the inlet cylinder pipe 15 and the outlet cylinder pipe 16 are rotatably connected with internal thread sealing sleeves 17. Two butt pipes 22 threadedly connected to the internal thread sealing sleeves 17 are connected to the side wall of the sand filter tank 5. A sliding connector for moving the support plate 4 closer to or farther away from the backwash controller 11 is provided on the bottom surface of the equipment box 1.

[0029] Refer to Figure 4 As shown, the bolt connector 3 includes a fixing plate 3a fixedly connected to the upper part of the side wall of the sand filter tank 5. A bolt 3b is fixedly connected to the upper surface of the fixing plate 3a. A fixing sleeve 3c sleeved with the bolt 3b is fixedly connected to the side wall of the upper cover 6. A nut 3d threadedly connected to the bolt 3b is provided above the fixing sleeve 3c. After the upper cover 6 is located at the upper opening of the sand filter tank 5, at this time, a plurality of fixing sleeves 3c are simultaneously sleeved on a plurality of bolts 3b, and then the fastening nut 3d is rotated to drive the fixing sleeve 3c and the upper cover 6 to press down to complete the sealing installation.

[0030] Specifically, a filling basket 25 is provided inside the sand filter tank 5. The filling basket 25 is frustum-shaped, and its height is adapted to the height of the upper cover 6. The filling basket 25 can make up for the missing part of the filter material between the sand filter tank 5 and the upper cover 6. When the filter material inside the sand filter tank 5 is filled to the opening, the filling basket 25 is placed on the top of the filter material, and then the filter material is continuously added to the filling basket 25 until the filling basket 25 is filled, and then the upper cover 6 is docked and installed with the sand filter tank 5.

[0031] Refer to Figure 3As shown in FIGS. 4 or 5, four convex rods 26 evenly distributed in a circumferential manner with the axis of the sand filter tank 5 as the reference are fixedly connected to the bottom surface of the sand filter tank 5. Four concave holes 27 into which the convex rods 26 are inserted are formed through the support plate 4. After the sand filter tank 5 is placed on the surface of the support plate 4, the convex rods 26 are inserted into the concave holes 27 to prevent the sand filter tank 5 from being misaligned on the surface of the support plate 4. At the same time, the docking process between the docking pipe 22 and the internal thread sealing sleeve 17 can be made more accurate.

[0032] Referring to Figures 2 - 3 As shown in the figure, the sliding connector includes two track plates 18 fixedly connected to the inner bottom of the equipment box 1. The upper surfaces of the two track plates 18 are both provided with sliding grooves 21. Four roller seats 19 are fixedly connected to the bottom surface of the support plate 4. Rollers 20 in contact with the sliding grooves 21 are rotatably connected in the four roller seats 19. The four rollers 20 are distributed in two sliding grooves 21 in pairs. After the sand filter tank 5 is placed on the upper surface of the support plate 4 and moved, the support plate 4 is driven to move on the two track plates 18. At the same time, the rollers 20 roll in the sliding grooves 21 to make the moving process smoother, so as to achieve the purpose of docking the docking pipe 22 with the internal thread sealing sleeve 17.

[0033] Specifically, a sealing ring 24 is fixedly connected to the upper end opening of the sand filter tank 5. A sealing groove 23 adapted to the sealing ring 24 is formed at the bottom opening of the upper cover 6. After the upper cover 6 is installed on the sand filter tank 5, the sealing ring 24 is fitted into the sealing groove 23 to achieve a sealing effect and prevent liquid leakage.

[0034] Referring to Figure 2As shown in the figure, a sewage discharge pipe 8, a water inlet pipe 7 and a water outlet pipe 9 are successively connected to the upper part of one side wall of the equipment box 1. A circulation pump 12 is fixedly installed at the lower part of the side wall of the equipment box 1. A sterilizer 10 is fixedly installed at the upper part of the other side wall of the equipment box 1. A medicine feeder 13 is arranged below the sterilizer 10, and the medicine feeder 13 is fixedly installed on the inner wall of the equipment box 1. A pressure sensor 28 is fixedly installed at the upper end of the upper cover 6. The water inlet pipe 7 is communicated with the input end of the circulation pump 12. The output end of the circulation pump 12 is communicated with the input end of the backwash controller 11. The other two output ends of the backwash controller 11 are respectively communicated with the sewage discharge pipe 8, the sterilizer 10 and the medicine feeder 13. Valves 14 are arranged on both sides of the medicine feeder 13. The backwash controller 11 can automatically control the backwash action of the sand filter tank operation. When there is a lot of filtered dirt deposited inside the sand filter tank 5, it affects the water flow passability. At this time, the internal pressure of the sand filter tank 5 increases. Through the pressure sensor 28 on the upper cover 6 for inspection, when the pressure value for the sand filter tank 5 flushing setting is reached, the backwash controller 11 starts to work for automatic backwashing. It is also possible to perform backwashing by setting a time schedule. When either the pressure or the time schedule meets one of the conditions, the backwash action is carried out. Operating in this way replaces the traditional manual six-way valve, without the need for manual rotation of the valve by workers. After the whole set of equipment is set up, it automatically runs the filtration, backwashing and sewage discharge actions, saving the manual regular maintenance, and also avoiding the loss of equipment blockage and damage caused by the negligence of maintenance personnel not performing maintenance after the equipment is installed. It saves manpower and improves the filtration efficiency of the equipment at the same time.

[0035] With the above structure, by rotating the two internal thread sealing sleeves 17, gradually separating them from the butt joint pipe 22 until they fall off, and then translating the sand filter tank 5 and the support plate 4 through the sliding connecting piece. At this time, by lifting the sand filter tank 5, the tank body can be taken out of the equipment box 1. Then, by removing the restriction on the upper cover 6 through the bolt connecting piece 3, the upper cover 6 can be removed at this time. By turning the sand filter tank 5 over, the filter media can be taken out completely at one time, improving the replacement efficiency.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
