[0031] like Figures 1 to 7As shown, the present invention provides a wastewater treatment device for drainage and gas production, including a filter tank 1, a discharge port 2 and a feed port 3. A servo motor 4 is provided at the upper end of the outer side of the filter tank 1, and a vertical cylinder 20 is provided at the output end of the servo motor 4. The vertical cylinder 20 is rotatably connected to the outer cover 26, and the outer cover 26 is welded to the output end of the reagent box 5. One end of the vertical cylinder 20 is located in the filter tank 1, and a mesh tube 18 is welded to the internal vertical cylinder 20. The output end of the mesh tube 18 is overlapped on the baffle 19 and the collection port 23, and a mesh pipe 22 is welded on the collection port. One end of the mesh pipe 22 is located outside the filter tank 1, and a debris discharge port 6 is welded to the external mesh pipe 22. By setting a tapered mouth 28 inside the filter tank, the waste water will be collected into the inside of the mesh tube 18 through the tapered mouth 28, and finally flow into the inside of the filter tank 1 through the mesh tube 18. The waste water will be filtered after passing through the mesh tube 18, and large impurities will be stored in the mesh tube 18. The mesh tube 18 is welded on the vertical tube 20, and the servo motor 4 can drive the mesh tube 18 to rotate, and the leakage port 25 of the mesh tube 18 will rotate toward the collection port 23. After the leakage port 25 corresponds to the collection port 23, the large impurities will be flushed into the collection port 23, and then moved to the position of the impurity discharge port 6 through the mesh tube 22, and the staff can handle the large impurities separately. The whole filtering process does not require frequent cleaning of the mesh tube 18, and the mesh tube 18 can maintain an efficient filtering state, which is convenient for the staff to use.

[0032] The reagent box 5 is provided with a connecting pipe 7, the output end of the connecting pipe 7 is provided on a storage box 8, the storage box 8 is welded on the outer cover 26, the storage box 8 is provided in a rectangular shape as a whole, the outer cover 26 is provided in a cylindrical shape as a whole, the inner diameter of the outer cover 26 is the same as the outer diameter of the vertical cylinder 20, and the vertical cylinder 20 is connected to the outer cover 26 through. By providing the reagent box 5 on the filter tank 1, the reagent can be added during the filtering process, so that the wastewater after the preliminary filtration can be mixed with the reagent and precipitated, thereby reducing the steps of the reagent addition in the next procedure, thereby improving the efficiency of wastewater treatment.

As the mesh cylinder 18 rotates, it will carry the large impurities to move. When the leakage port 25 of the mesh cylinder 18 moves to the collection port 23, the large impurities will be flushed into the mesh pipe 22, and the large impurities will be processed separately, so as not to block the mesh cylinder 18. The mesh cylinder 18 can filter large impurities without affecting the flow of the water body, thereby ensuring high efficiency of filtration. Large impurities can be discharged separately during the filtration process, so there is no need to clean the mesh cylinder 18 separately. Large impurities can be collected separately after filtration, which is convenient for the operation of the staff. The setting can bring convenience to the staff.

[0035] A top seat 12 is welded to the vertical cylinder 20 above the outer cover 26. The top seat 12 is arranged in an arc shape as a whole.

During the activity, the top seat 12 will reciprocate to the position of the top head 11. When it moves to the position of the top head 11, it will push the top head 11, and the top head 11 will drive the slide bar 14 to move. When it is away from the top head 11, the slide bar 14 will be driven by the first spring 10 to reset.

[0036] The slide bar 14 is slidably connected to the bracket 13, and the bracket 13 is vertically arranged on the storage box 8. A linkage frame 15 is welded on the slide bar 14, and the linkage frame 15 is arranged in an F shape as a whole. A first spring 10 is sleeved on the slide bar 14 between the linkage frame 15 and the bracket 13, and one end of the first spring 10 is hung on the bracket 13. By arranging a linkage rod on the slide bar 14, the linkage rod will move with the slide bar 14, and when it moves, it will drive the knocking frame 16 to swing, and the knocking frame 16 will drive the rubber head 17 to knock on the storage box 8, thereby preventing the medicine from being blocked.

[0037] The storage box 8 is welded with a side frame 9, which is arranged obliquely on the storage box 8. The side frame 9 is rotatably connected with a knocking frame 16, which is provided with a rubber head 17. The knocking frame 16 is clamped in the linkage frame 15. The knocking frame 16 can be limited by the side frame 9, and the knocking frame 16 will swing at the position of the side frame 9.

[0038] A conical port 28 is welded inside the filter tank 1, and a mesh tube 18 is overlapped at the small end position of the conical port 28. The inside of the mesh tube 18 and the inside of the conical port 28 are mutually connected, and the vertical tube 20 on the mesh tube 18 is connected to the conical port 28. The wastewater can be guided through the conical port 28, and the wastewater will flow to the position of the mesh tube 18, so as to be filtered by the mesh tube 18.

[0039] A partition 24 is welded on the net cylinder 18, and the partition 24 is arranged in a circular plate shape as a whole. A leakage opening 25 is opened on the partition 24, and the leakage opening 25 is arranged in an arc shape as a whole. The partition 24 is overlapped on the baffle 19. The net cylinder 18 can be blocked by the partition 24 to prevent the leakage opening 25 from being too large to cause wastewater to flow directly to the net pipe 22, and to prevent wastewater from being discharged to the outside of the filter tank 1 through the net pipe 22.

[0040] The baffle 19 is arranged in a disk shape as a whole, and the diameter of the baffle 19 is larger than the diameter of the net tube 18. A collection port 23 is welded on the baffle 19, and the collection port 23 and the leakage port 25 are mutually connected. The collection port 23 can realize the collection of large impurities, and the large impurities will be discharged through the net tube 22.

[0041] The support 13 is provided on the storage box 8, and the slide bar 14 can be installed on the support 13, and the slide bar 14 can slide reciprocatingly along the support 13. One end of the slide bar 14 is provided with a head 11, and a top seat 12 is provided on the vertical cylinder 20 corresponding to the head 11. The top seat 12 can rotate with the vertical cylinder 20, and the head 11 can be pushed back and forth by rotation. After the head 11 is pushed by the top seat 12, it will slide, and the slide bar 14 will drive the knocking frame 16 to swing through the linkage frame 15, and the knocking frame 16 will rotate toward the storage box 8 position, thereby driving the rubber head 17 to knock the storage box 8. When the knocking frame 16 knocks the storage box 8 back and forth, the storage box 8 will vibrate, so that the internal medicine can be loosened to prevent the medicine from being blocked in the storage box 8, thereby ensuring that the medicine can flow into the vertical cylinder 20, and the medicine can enter the filter tank 1 through the vertical cylinder 20 and mix with the wastewater, thereby realizing the dosing during wastewater pretreatment.

[0042] like Figure 1-7 As shown, a method for treating wastewater used for drainage and gas production comprises the following steps:

[0043] S1: The wastewater passes through the feed port 3 of the filter tank 1 and finally falls on the conical port 28. As the wastewater flows, it flows into the inner part of the net cylinder 18. Large impurities will be filtered after passing through the net cylinder 18. After starting the servo motor 4, the vertical cylinder 20 will drive the net cylinder 18 to rotate, and the leakage port 25 of the net cylinder 18 will rotate along the baffle 19, and the leakage port 25 can be blocked by the baffle 19;

[0044] S2: With the rotation of the mesh tube 18, the leakage port 25 will move to the collection port 23. With the flow of wastewater, large impurities will be washed into the collection port 23, and the large impurities will be able to move along the mesh tube 22. The wastewater will be discharged into the filter tank 1 through the mesh tube 22 and will not be discharged to the outside of the filter tank 1 along with the large impurities. With the rotation of the vertical cylinder 20, the opening 27 will move to the storage box 8. The medicine will be discharged into the filter tank 1 through the vertical cylinder 20, so that it can be initially precipitated after mixing with the wastewater.

[0045] The working principle of the present invention is as follows: by arranging a servo motor 4 on the filter tank, the servo motor 4 can drive the vertical cylinder 20 to rotate in the filter tank 1, and the filtered wastewater can be stirred by the stirring frame 21 on the vertical cylinder 20, so that the mixing of the medicine is convenient when the medicine is discharged into the wastewater. A mesh cylinder 18 is welded on the vertical cylinder 20, and the mesh cylinder 18 can rotate with the vertical cylinder 20. When the wastewater falls on the mesh cylinder 18, it will be filtered, and large impurities will stay in the mesh cylinder 18. As the mesh cylinder 18 rotates, it will carry the large impurities to move. When the leakage port 25 of the mesh cylinder 18 moves to the collection port 23, the large impurities will be flushed into the mesh pipe 22, and the large impurities will be processed separately, so as not to block the mesh cylinder 18. The mesh cylinder 18 can filter large impurities without affecting the flow of the water body, thereby ensuring the high efficiency of the filtration. The large impurities can be discharged separately during the filtration process, so that there is no need to clean the mesh cylinder 18 separately. The large impurities can be collected separately after filtering, which is convenient for the operation of the staff. The arrangement can bring convenience to the staff. By arranging a bracket 13 on the storage box 8, a slide bar 14 can be installed on the bracket 13, and the slide bar 14 can slide back and forth along the bracket 13. A top head 11 is arranged at one end of the slide bar 14, and a top seat 12 is arranged on the vertical cylinder 20 corresponding to the top head 11. The top seat 12 can rotate with the vertical cylinder 20, and the top head 11 can be reciprocated by rotating. After the top head 11 is pushed by the top seat 12, it will slide, and the slide bar 14 will pass The linkage frame 15 drives the knocking frame 16 to swing, and the knocking frame 16 will rotate toward the storage box 8, thereby driving the rubber head 17 to knock the storage box 8. When the knocking frame 16 knocks the storage box 8 back and forth, the storage box 8 will vibrate, so that the internal medicine can be loosened to prevent the medicine from being blocked in the storage box 8, thereby ensuring that the medicine can flow into the vertical cylinder 20. The medicine can enter the filter tank 1 through the vertical cylinder 20 and mix with the wastewater, thereby realizing the dosing during wastewater pretreatment.

The wastewater is discharged into the filter tank (1) through the net tube (22) and will not be discharged to the outside of the filter tank (1) along with the large impurities. As the vertical tube (20) rotates, the opening (27) moves to the position of the storage box (8). The reagent is discharged into the filter tank (1) through the vertical tube (20), so that it can be initially precipitated after mixing with the wastewater.
