In order to improve the filtration efficiency, the filter grid needs to be cleaned regularly. However, in the current sewage purification process, the fixing methods of the filter grid are mostly inconvenient to disassemble, or the filter grid is easily damaged during disassembly. How to quickly disassemble the filter grid without damaging the grid is an urgent problem to be solved. Summary of the Invention

[0020] In order to further understand the purpose, structure, features and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0021] In view of the above problems, the present utility model provides a grid filter, see Figure 1 , Figure 1 is a schematic diagram of a grid filter of the present utility model, which includes a filter box body 1 and a filter grid 4. An inlet 2 is arranged on the first side of the filter box body 1, and an outlet 3 is arranged on the second side of the filter box opposite to the inlet 2; the filter grid 4 is arranged in the filter box body 1 and is perpendicular to the direction of the inlet 2. At least one inner side of the filter box body 1 except for the sides where the inlet 2 and the outlet 3 are located is provided with two parallel limiting plates 5, and the two parallel limiting plates 5 fix the filter grid 4. A vertical side of the filter grid 4 is inserted between the two parallel limiting plates 5 and is fixed by these two limiting plates 5 so that the filter grid 4 is in a vertical state.

[0022] Furthermore, a filtering medium 6 is arranged in the filtering box body 1, and the filtering medium 6 is arranged in parallel with the filtering grid 4. The filtering medium 6 is arranged at a position close to the water outlet 3. When sewage flows into the filtering box body 1 through the water inlet 2, it is first filtered by the filtering grid 4 to isolate large-particle impurities in the sewage. The sewage after removing the large-particle impurities is further filtered by the filtering medium 6. The fixing method of the filtering medium 6 is the same as that of the filtering grid 4, and is fixed by two parallel limiting plates 5 arranged in the filtering box body 1. A vertical side of the filtering medium 6 is inserted between the two parallel limiting plates 5 and fixed by the limiting plates 5 so that the filtering medium 6 is in a vertical state.

[0023] Furthermore, the filtering grid 4 is a strip-shaped filtering grid. In the present utility model, the filtering grid 4 is a strip-shaped filtering grid. In actual use, a mesh filtering grid or other perforated filtering grids can also be adopted, and the present utility model does not limit this.

[0024] For better fixing and disassembling of the filtering grid 4, refer to Figure 2 , Figure 2 which is a schematic diagram of the first embodiment of the limiting plate of the present utility model. The present utility model extends the extension part of the limiting plate 5 into an arc shape, and fixes the filtering grid through the buffering characteristic of the arc shape. The present utility model can design the extension part of one of the two parallel limiting plates into an arc shape, or can also set the extension parts of the two parallel limiting plates into arc shapes. Specifically, the range of the arc radius is between 10 mm and 20 mm. In actual production, when the arc shape formed by the extension part of the limiting plate has a radius between 10 mm and 20 mm, the fixing and disassembling force of the filtering grid is more appropriate. However, the present utility model does not limit the arc radius of the extension part of the limiting plate 5. It should be noted that this fixing method with the extension part of the limiting plate 5 being in an arc shape can also be applied to the filtering medium.

[0025] In another embodiment, refer to Figure 3 , Figure 3 which is a schematic diagram of the second embodiment of the limiting plate of the present utility model. The present utility model bends the extension part of the limiting plate 5 into an angle and fixes the filtering grid through the buffering characteristic of the bending angle. The present utility model can bend the extension part of one of the two parallel limiting plates 5 into an angle, or can also bend the extension parts of the two parallel limiting plates 5 into angles. Specifically, the range of the angle after bending the limiting plate 5 is between 20 degrees and 30 degrees. In actual production, when the range of the angle after bending the limiting plate 5 is between 20 degrees and 30 degrees, the fixing and disassembling force of the filtering grid 4 is more appropriate. However, the present utility model does not limit the angle of the extension part of the limiting plate 5 being bent. It should be noted that this fixing method with the extension part of the limiting plate 5 being bent into an angle can also be applied to the filtering medium 6.

[0026] Furthermore, the filter may further include a cover body disposed above the filter box body 1 to prevent sewage from splashing out during the sewage filtration process.

[0027] The utility model provides a grid filter, which includes a filter box body, a filter grid and a filter cover body. An inlet is provided on the first side of the filter box body, and an outlet is provided on the opposite side. The filter grid is disposed in the filter box body and is perpendicular to the direction of the inlet. At least two parallel limiting plates are provided on at least one inner side of the filter box body, and the two parallel limiting plates fix the filter grid. The utility model fixes the filter grid through the limiting plates, which increases the convenience of installation and disassembly of the filter grid and does not damage the filter grid.
