[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] See Figures 1 to 5 , a sewage treatment device for grading slag interception, including a filtration tank 1. On both side walls along the length direction in the filtration tank 1, guide rails 2 are provided at multiple angles facing each other. A grid plate 3 is inserted in the guide rails 2. At the end floor along the length extension direction in the filtration tank 1, a drain port 4 is provided.

[0026] Preferably, the filtration tank 1 is a rectangular tank body, and the top of the filtration tank 1 is an open design.

[0027] Preferably, the guide rail 2 is a groove-shaped structure. On the side wall of the guide rail 2 on the side facing the water inlet surface, magnetic points 2.4 are provided. The guide rail 2 includes a first guide rail 2.1, a second guide rail 2.2, and a third guide rail 2.3. The first guide rail 2.1 is arranged along the inner wall with an inclination of 45°. The second guide rail 2.2 is arranged vertically along the inner wall. The third guide rail 2.3 is arranged along the inner wall at an angle of 60° with the bottom plate. The first guide rail arranged along the inner wall with an inclination of 45° enables the first grid plate to be arranged in the filtration tank at 45°. When sewage enters, it can directly fall onto the first grid plate. Under the action of gravity, the water accelerates through, and it also plays a role in pushing the water in the tank, further reducing the risk of blockage. The third guide rail arranged at 60° can further improve the water passing rate and reduce the number of silt cleaning times.

[0028] Preferably, the bottom end of the first guide rail 2.1 is connected to the inner side wall of the filtration tank 1 along the width direction. The bottom end of the second guide rail 2.2 is vertically connected to the bottom plate of the filtration tank 1. The inclined direction of the third guide rail 2.3 faces the side of the filtration tank 1 where the drain port 4 is provided.

Handles 3.4 are provided on the top of the grid plate 3. The grid plate 3 includes a first grid plate 3.1, a second grid plate 3.2 and a third grid plate 3.3. The grid plate 3 is magnetically attachable to the side of the guide rail 2 provided with magnetic points 2.4. By providing handles, it is convenient to disassemble the grid plate. Before replacing the grid plate, the grid plate of the same specification can be temporarily arranged on the side of the guide rail provided with magnetic points in a magnetic adsorption manner. After the grid plate is cleaned or replaced, and then inserted back into the filter tank through the guide rail, the temporarily placed grid plate is removed, without interrupting the sewage filtration treatment, thus improving the work efficiency.

[0030] Preferably, the first grid plate 3.1 is detachably inserted into the first guide rail 2.1, the second grid plate 3.2 is detachably inserted into the second guide rail 2.2, and the third grid plate 3.3 is detachably inserted into the third guide rail 2.3. This design of hierarchical filtration effectively avoids the blockage of the grid plate and the sewage discharge port, reduces the maintenance frequency, and improves the continuity and stability of sewage treatment.

[0031] Preferably, the width of the grid gaps in the first grid plate 3.1 is 20 mm, the spacing between the grid gaps in the first grid plate 3.1 is 5 mm, the shape of the grid gaps in the first grid plate 3.1 is a rectangular hole, the width of the grid gaps in the second grid plate 3.2 is 10 mm, the spacing between the grid gaps in the second grid plate 3.2 is 5 mm, and the shape of the grid gaps in the second grid plate 3.2 is a rectangular hole. The first grid plate with larger gaps can initially intercept larger slag, and the second grid plate further filters smaller impurities.

[0032] Preferably, the shape of the grid gaps in the third grid plate 3.3 is a round hole, the aperture of the upper grid gaps in the third grid plate 3.3 is 5 mm, and the aperture of the middle and lower grid gaps in the third grid plate 3.3 is 3 mm. The third grid plate realizes fine filtration.

[0033] The working principle of this embodiment is as follows:
