[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 4 As shown, a wastewater treatment granular filter screen includes a treatment box 1, an arc-shaped screen 2, and a feed pipe 3. The treatment box 1 is equipped with an inlet pipe 4 and a outlet pipe 5. It also includes a fixed part 6, a movable part 7, a telescopic cylinder 8, a U-shaped frame 9, a limiting magnetic suction assembly, and a porous arc-shaped support plate 10.

[0028] The processing box 1 includes a fixed part 6 and a movable part 7;

[0029] Two telescopic cylinders 8 are respectively fixed on the fixed part 6 and the feeding pipe 3, and the telescopic cylinders 8 are connected to the movable part 7;

[0030] Two U-shaped frames 9 are spaced apart on the arc-shaped screen 2, and the U-shaped frames 9 are connected to the movable part 7 through a limiting magnetic suction assembly to accurately define the initial installation position of the arc-shaped screen 2;

[0031] Two perforated arc-shaped support plates 10 are inclinedly fixed on the two side walls of the processing box 1, and the perforated arc-shaped support plates 10 are attached to the bottom ends of the arc-shaped screen 2.

[0032] Further refinements of the embodiments of this utility model, such as... Figures 1 to 4 As shown, the limiting magnetic suction assembly includes a tube 11, a post 12 and a magnet 13. Two U-shaped frames 9 with different lengths and the same height at the top are respectively fixed with post 12. The inner wall of the movable part 7 is fixed with a tube 11 that corresponds to the post 12 and is adapted in size. The top of the inner wall of the tube 11 is fixed with a magnet 13.

[0033] In a further optimization of the above embodiment, the insert 12 is made of 430 stainless steel.

[0034] To ensure that the wastewater after filtering solid particles can flow smoothly out of treatment tank 1, further optimization of the solution is needed, such as... Figure 4 As shown, a flow guide platform 14 is fixedly installed at the bottom of the interior of the treatment box 1 at an incline, and the flow guide platform 14 is connected to the drain pipe 5.

[0035] In a further optimization of the above embodiment, the drain pipe 5 is connected to a suction pump, which is not shown in the figure. By using the suction pump in conjunction with the guide platform 14, the amount of water remaining at the bottom of the treatment tank 1 after filtering solid particles can be further reduced.

[0036] It should be noted that the telescopic cylinder 8 is electrically connected to the controller, which is located on the rear side of the processing box 1.

[0037] The working process of this utility model is as follows:

[0038] First, the controller controls the two telescopic cylinders 8 to operate synchronously, which causes the movable part 7 to move upward (the movement distance is preset). After the movable part 7 completes its movement, it aligns the two inserts 12 on the arc-shaped screen 2 with the two insert cylinders 11 and inserts them. At this point, the installation position of the arc-shaped screen 2 can be accurately defined. When the inserts 12 come into contact with the magnet 13, the arc-shaped screen 2 can be attracted (as per the instruction manual). Figure 4 As shown in the figure, the telescopic cylinder 8 is then retracted by the controller so that the end face of the movable part 7 is reconnected with the end face of the fixed part 6. At this time, the bottom of the arc-shaped screen 2 contacts the porous arc-shaped support plate 10 and is effectively supported, and the two sides of the arc-shaped screen 2 are attached to the inner wall of the treatment box 1. At this time, the filtration process of solid particles in sewage can be carried out, and the position of the arc-shaped screen 2 will not shift in the subsequent filtration process.

[0039] Sewage is then introduced through the inlet pipe 4. At this time, the solid particles in the sewage remain on the arc-shaped screen 2. The remaining water flows through the arc-shaped screen 2 and out through the drain pipe 5. The water flow can cause the solid particles to move towards the feed pipe 3. Then most of the solid particles can flow out of the sewage tank along the feed pipe 3 (it should be noted that not all solid particles can flow out. After the sewage has been treated for a period of time, the arc-shaped screen 2 needs to be disassembled to clean the remaining solid particles attached to its surface). At this time, the two telescopic cylinders 8 are extended synchronously again, which can make the arc-shaped screen 2 move to the outside area of ​​the treatment box 1 again. Then, manual force can be applied to make the arc-shaped screen 2 detach from the magnet 13. Then, the remaining solid particles on its surface can be cleaned. In summary, the arc-shaped screen 2 can be disassembled for cleaning or maintenance at any time. It should be noted that when no force is applied, the magnet can ensure the adsorption effect on the column. Even if a small amount of solid particles are attached to the arc-shaped screen, the two will not detach.

[0040] To achieve automatic sewage flow into treatment tank 1 without affecting the disassembly and cleaning process of the arc-shaped screen 2, in some embodiments, such as Figure 5As shown, a sealing plate 15 is fixed on the inlet pipe 4. The sealing plate 15 is connected to the sewage pump fixed in another area via a hose 16, and one end of the hose 16 is connected to the inside of the treatment tank 1. The sewage pump is connected to the sewage tank. Neither the sewage pump nor the sewage tank is shown in the figure. (It should be noted that the movement distance of the movable part 7 is determined. At the same time, the hose 16 is kept aligned with the pump body axis during the lifting and lowering process. In addition, the tightness and wear of the hose 16 joints are checked regularly to ensure that the automatic sewage inlet process and the disassembly and assembly process of the arc-shaped screen 2 do not affect each other.)

[0041] In order to improve the sealing effect after the movable part 7 and the fixed part 6 are connected, in other embodiments, a sealing element is provided on the end face of the movable part 7. The sealing element is not shown in the figure, but a sealing gasket can be used.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
