Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to an environmental protection device for sewage filtration. Background Technique

[0002] Sewage refers to the discharged water from life and production that is contaminated to a certain extent. The water that has lost its original use function is simply called sewage, mainly the water used in daily life, which contains more organic matter and is relatively easy to treat. As is well known, an environmental protection sewage filtration device is an auxiliary device used in the process of sewage treatment to filter sewage for subsequent purification, and it is widely used in the field of environmental protection.

[0003] For example, Chinese Patent Publication No. CN218421322U discloses an environmental protection sewage filtration device, which includes a box body. The middle part of the upper surface of the box body is communicated with a water inlet pipe. The middle part of the front surface of the box body is provided with an observation window. The bottom of both the left and right sides of the box body is communicated with a drain valve. The top of the right side of the box body is inserted with an installation frame, and installation feet are installed on both the front and rear sides of the right side of the installation frame. For this environmental protection sewage filtration device, by the user turning the adjusting bolt, the adjusting bolt drives the sliding plate to slide along the limit slide rail, and the sliding plate drives the clamping block to move horizontally.

[0004] However, in the above solution, when it is necessary to clean the impurities on the surface of the filter screen, the filtration of sewage needs to be stopped before the filter screen can be disassembled and cleaned, which affects the filtration efficiency of sewage and the convenience is not high.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Please refer to Figures 1-4 , in the embodiment of this utility model, a sewage filtration environmental protection device includes two filter boxes 1. The left side walls of the two filter boxes 1 are fixedly connected with water inlet pipes 2. The two water inlet pipes 2 are both communicated with the corresponding filter boxes 1. One ends of the two water inlet pipes 2 are jointly fixedly connected with a water inlet three-way pipe 4. A water inlet three-way valve 3 is provided on the side wall of the water inlet three-way pipe 4. The right side walls of the two filter boxes 1 are fixedly connected with drain pipes 7. The two drain pipes 7 are both communicated with the corresponding filter boxes 1. One ends of the two drain pipes 7 are jointly fixedly connected with a drain three-way pipe 9. A drain three-way valve 8 is provided on the side wall of the drain three-way pipe 9. Sliding grooves 6 are opened on both side walls inside the two filter boxes 1. Filter meshes 5 are provided inside the two filter boxes 1. The two filter meshes 5 are respectively slidably connected in the two sliding grooves 6 inside each filter box 1. Disassembly structures are provided on the tops of the two filter boxes 1. The bottoms of the two filter boxes 1 are fixedly connected with slag discharge pipes 10. The two slag discharge pipes 10 are both communicated with the corresponding filter boxes 1. Sealing caps 11 are threadedly connected to one ends of the two slag discharge pipes 10.

[0026] Please refer to Figures 1-4, the two disassembly structures include two T-shaped grooves 15 which are respectively opened on the top side walls of the two filter boxes 1. One ends of the two filter meshes 5 are respectively slidably connected to the two T-shaped grooves 15. Sealing plates 13 are slidably connected in both of the two T-shaped grooves 15. The side walls of the two sealing plates 13 are fixedly connected in the T-shaped grooves 15 through two bolts 14. The bottoms of the two sealing plates 13 are respectively abutted against the bottom side walls of the two T-shaped grooves 15. The tops of the two filter meshes 5 are respectively abutted against the bottom side walls of the two sealing plates 13. Sealing gaskets are provided at the bottoms of the two sealing plates 13. By turning the two bolts 14 at the rear side and taking out the two bolts 14, the sealing plate 13 on the side wall of the rear filter box 1 can be removed, and thus the filter mesh 5 in the rear filter box 1 can be taken out, so that the impurities stuck in the filter mesh 5 can be cleaned. Therefore, when cleaning the filter mesh 5 in one of the filter boxes 1, the sewage can pass through the other filter box 1 for filtration, and there is no need to stop the flow of the sewage to clean the filter mesh 5, thus improving the filtration efficiency of the sewage.

[0027] Please refer to Figures 1-4 , fixedly connected to the tops of the two sealing plates 13 are handles 12. The sealing plates 13 can be pulled out by lifting the handles 12, which is more convenient.

[0028] Please refer to Figures 1-4 , all four bolts 14 are made of stainless steel to prevent the four bolts 14 from being affected by rust during use.

[0029] Please refer to Figure 1 , the side walls at one ends of the inner bottoms of the two filter boxes 1 are both inclined. The two slag discharge pipes 10 are respectively located at the lowest positions of the inclined side walls of the inner bottoms of the two filter boxes 1, which can make the impurities at the inner bottoms of the two filter boxes 1 quickly move along the inclined side walls to the two slag discharge pipes 10, thus facilitating the quick cleaning of the impurities at the inner bottoms of the filter boxes 1.

[0030] Please refer to Figure 1 、 Figures 3-4 , the two filter meshes 5 and the four sliding grooves 6 are both inclined, so that the impurities adhering to the surfaces of the filter meshes 5 can fall downward into the slag discharge pipes 10 under their own weights.

[0031] The working principle of the utility model is as follows: Sewage enters the filter box 1 through the water inlet three-way pipe 4 and the water inlet pipe 2. The impurities in the sewage can be filtered through the provided filter net 5. Larger impurities will fall into the slag discharge pipe 10 through the side wall of the filter net 5. The filtered water is discharged through the drain pipe 7 and the drain three-way pipe 9. When it is necessary to clean one of the filter nets 5, the water inlet three-way valve 3 can be rotated to make the sewage enter the front filter box 1 through the front water inlet pipe 2 for filtration. Then, by rotating the sealing cover 11 at the bottom of the rear filter box 1, the impurities in the slag discharge pipe 10 are discharged. By rotating the two bolts 14 at the rear, the two bolts 14 are taken out, and the sealing plate 13 on the side wall of the rear filter box 1 can be removed, so that the filter net 5 in the rear filter box 1 can be taken out, and the impurities stuck in the filter net 5 can be cleaned. Thus, when cleaning the filter net 5 in one of the filter boxes 1, the sewage is filtered through the other filter box 1, and there is no need to stop the flow of sewage to clean the filter net 5, thereby improving the filtration efficiency of the sewage.
