[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1

[0031] like Figures 1-7 As shown, a wastewater treatment device includes a filter box 1, an inlet 2, an outlet 3, and a filter screen 4. Each of the four walls of the filter box 1 is equipped with an adjusting plate 5. The adjusting plate 5 has a plurality of insertion holes 41 evenly arranged along its length. The adjusting plate 5 is equipped with insertion blocks 6, the size of which matches the size of the insertion holes 41. The distance between two adjacent insertion holes 41 is the same as the thickness of the filter screen 4. The filter screen 4 is located between upper and lower insertion blocks 6. A U-shaped hook 7 is provided at the top of the filter box 1 wall, and the adjusting plate 5 is connected to the filter box 1 via the U-shaped hook 7.

[0032] The above technical solution involves first inserting two insert blocks 6 into the two adjacent holes 41 of the adjusting plate 5. At this point, the filter screen 4 is supported and limited by the upper and lower insert blocks 6, and all four sides of the filter screen 4 are fixed by the adjusting plate 5 and the insert blocks 6. Then, the filter screen 4, adjusting plate 5, and insert blocks 6 are placed into the filter box 1 as a whole. Next, one end of the adjusting plate 5 is connected to the U-shaped hook 7. This connects the filter screen 4, adjusting plate 5, and filter box 1, ensuring that the filter screen 4 is horizontal within the filter box 1 and does not shake during filtration. The adjusting plate 5 facilitates the removal of the filter screen 4 from the filter box 1, and also facilitates disassembly and assembly, improving efficiency.

[0033] Furthermore, the insertion block 6 has an L-shaped structure, and the insertion block 6 includes a side plate 61 and a bottom plate 62. The width of the side plate 61 is the same as the width of the adjusting plate 5, and the bottom plate 62 is inserted into the insertion hole 41.

[0034] Through the above technical solution, the insert 6 has an L-shaped structure, and the inserts 6 on the upper and lower sides of the filter screen 4 are symmetrically arranged. The bottom plate 62 abuts against the filter screen 4 and supports the filter screen 4 through the bottom plate 62. At the same time, since the adjustment plate 5 is provided with multiple insertion holes 41, the filter screen 4 can be conveniently placed in different positions of the adjustment plate 5. Thus, after the filter screen 4 is put into the filter box 1 through the adjustment plate 5, it can reach different depths inside the filter box 1.

[0035] Furthermore, the filter screen 4 has grooves in the middle of its four sides. The depth of the grooves is the sum of the thickness of the adjusting plate 5 and the thickness of the side plate 61, and the width of the grooves is the same as the width of the adjusting plate 5.

[0036] With the above technical solution, the depth of the groove is just enough to fit the adjusting plate 5 and the side plate 61, and the width of the groove is the same as the width of the side plate 61 and the adjusting plate 5. This reduces the gap between the filter box 1 and the filter screen 4 after the filter screen 4 is placed in the filter box 1, thus preventing impurities from flowing out of the gap.

[0037] Furthermore, the U-shaped hook 7 is hung on the wall of the filter box 1, the thickness of the side plate 61 is the same as the thickness of one side of the U-shaped hook 7, and both sides of the U-shaped hook 7 are provided with first through holes 9 that match the size of the insertion hole 41. The top of the filter box 1 is also provided with a second through hole 10 that matches the size of the insertion hole 41. An insert 8 is provided between the adjusting plate 5 and the U-shaped hook 7. The cross-sectional size of the insert 8 matches the size of the insertion hole 41. The insert 8 passes through the insertion hole 41, the first through hole 9 and the second through hole 10.

[0038] With the above technical solution, the U-shaped hook 7 can slide on the wall of the filter box 1. After the adjusting plate 5 is connected to the filter screen 4 and placed into the filter box 1, the first through hole 9 on the U-shaped hook 7 is aligned with the second through hole 10 on the filter box 1. Then, according to the depth of the filter screen 4, the corresponding insertion hole 41 on the adjusting plate 5 is aligned with the first through hole 9 and the second through hole 10. At this time, the insertion strip 8 is inserted to complete the fixation of the adjusting plate 5, the U-shaped hook 7 and the filter box 1.

[0039] Furthermore, a sealing rubber ring is provided around the outer edge of the filter screen 4.

[0040] With the above technical solution, when the filter screen 4 is placed horizontally into the filter box 1, the sealing rubber around the filter screen 4 abuts against the filter box 1, reducing the gap between the filter screen 4 and the filter box 1, so that the water flows through the filter holes of the filter screen 4, thereby improving the filtration effect.

[0041] Furthermore, both the inlet 2 and the outlet 3 are equipped with one-way valves.

[0042] Through the above technical solution, sewage enters the filter box 1 from the inlet 2. The inlet 2 is located at the bottom of the filter box 1. Since the inlet 2 is equipped with a one-way valve, the sewage will not flow back after entering the filter box 1. The sewage in the filter box 1 gradually increases, and large particles of impurities in the sewage will settle to the bottom of the filter box 1. At the same time, as the sewage level in the filter box 1 gradually rises, the floating impurities will come into contact with the filter screen 4. The filter screen 4 can isolate the impurities, so that the filtered water flows out from the outlet 3 at the top.

[0043] Example 2

[0044] Based on Example 1, see as follows Figure 8 As shown, multiple filter screens 4 can be connected to the adjusting plate 5 via insert blocks 6, allowing filter screens 4 with various filter hole specifications to be placed in the filter box 1. Multiple filter screens 4 arranged vertically can filter sewage in multiple ways, improving the filtration effect. At the same time, multiple filter screens 4 can be easily removed and disassembled at one time, improving the efficiency of disassembly and cleaning.

[0045] Meanwhile, since the adjusting plate 5 is fixed to the U-shaped hook 7 and the filter box 1 by inserting the insert strip 8, and the adjusting plate 5 is provided with multiple insertion holes 41, the length of the adjusting plate 5 extending into the filter box 1 can be adjusted, thereby adjusting the depth of the filter screen 4 in the filter box 1, so as to facilitate the placement of the filter screen 4 according to actual needs.

[0046] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
