Technical Field
[0001] This utility model relates to the field of filtration technology, and in particular to a filtration device for detecting chemical wastewater. Background Technology
[0002] Chemical wastewater refers to the wastewater produced during the production process of chemical plants, such as oily wastewater from units producing ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank farms, and air separation and air compressor stations. Large particulate impurities generally need to be filtered before chemical wastewater testing.
[0003] However, it is worth considering that the filtered impurities will remain on the surface of the filter screen. As the usage time increases, the impurities will accumulate and clog the filter screen, requiring frequent shutdowns to clean the filter screen and remove the filtered impurities, thus affecting the filtration efficiency.
[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a filtration device for chemical wastewater testing, so as to solve the problem of needing to frequently stop the machine to clean the filter screen.
[0006] To achieve the above objectives, this utility model provides a filtration device for chemical wastewater detection, comprising a filter box and a box cover. The box cover is equipped with a disassembly and assembly mechanism adapted to the filter box. Water outlet pipes are fixedly connected to both sides of the filter box, and valves are provided on the water outlet pipes. Water inlet pipes are fixedly connected to the box cover. Two first filter plates are provided inside the filter box. The first filter plate is fixedly connected to the inner wall of the filter box on both sides and bottom. A second filter plate is provided between the two first filter plates, and the water inlet pipe is located above the second filter plate. Cleaning brushes that are compatible with the first filter plates are fixedly connected to both sides of the second filter plate. An adjustment structure for driving the second filter plate to rotate and lift is installed on the box cover.

A lifting frame passes through the cover of the filter box, and the telescopic end of the hydraulic telescopic rod is fixedly connected to the lifting frame. A rotator for driving the second filter plate to rotate is installed at the bottom end of the lifting frame.
[0008] Preferably, the self-rotator includes two control boxes fixedly installed at the bottom of the lifting frame. The control boxes are cylindrical structures. The two sides of the second filter plate are respectively provided with clearance holes adapted to the control boxes. The control boxes are located in the clearance holes. A waterproof motor is fixedly connected inside the control box, and the output end of the waterproof motor is fixedly connected to the second filter plate. The two sides of the second filter plate are in contact with the inner wall of the filter box.
[0009] Preferably, a drain pipe is fixedly connected to the bottom of the filter box, and the drain pipe is located below the second filter plate. A valve is provided on the drain pipe, and several support legs are fixedly connected to the bottom of the filter box.
[0010] Preferably, the disassembly and assembly mechanism includes fixed frames that are respectively fixedly installed on both sides of the box cover.

[0011] Preferably, the elastic element includes a fixed plate fixedly installed at the end of the insertion rod away from the limiting sleeve, and the fixed plate and the fixed frame are connected by a tension spring.
[0012] The beneficial effects of this utility model are as follows: Workers add the chemical wastewater to be filtered into the filter box through the inlet pipe. The wastewater enters between two first filter plates and is filtered by the first filter plates. The filtered wastewater is discharged through the outlet pipe. When the first filter plates filter out a large amount of impurities, the second filter plate is driven to move vertically back and forth by an adjustment structure. The second filter plate cleans the first filter plate with a cleaning brush. After cleaning, the second filter plate is tilted by an adjustment structure to prevent impurities from accumulating on top of it. The second filter plate is then moved up above the water surface by an adjustment structure, rotated to a horizontal position by an adjustment structure, and then lowered to its initial height. The second filter plate stores and collects the impurities below it, preventing the impurities filtered by the first filter plate from affecting its subsequent filtration effect. This allows for the collection and summarization of impurities filtered by the first filter plate without stopping the machine, ensuring filtration effect while improving filtration efficiency.

[0018] This specification provides one or more embodiments of a filtration device for detecting chemical wastewater, such as... Figure 1 and Figure 2 As shown, it includes a filter box 1 and a cover 2. The cover 2 is equipped with a disassembly and assembly mechanism that is compatible with the filter box 1. Water outlet pipes 3 are fixedly connected to both sides of the filter box 1, and valves are provided on the water outlet pipes 3. Water inlet pipes 4 are fixedly connected to the cover 2.

Cleaning brushes 7, which are compatible with the first filter plates 5, are fixedly connected to both sides of the second filter plate 6. An adjustment structure for driving the second filter plate 6 to rotate and lift is installed on the box cover 2. The operator adds the chemical wastewater to be filtered into the filter box 1 through the water inlet pipe 4. The wastewater enters between the two first filter plates 5 and is filtered by the first filter plates 5. The filtered wastewater is discharged through the water outlet pipe 3. When the first filter plate 5 filters out a lot of impurities, the adjustment structure drives the second filter plate 6 vertically upward. The second filter plate 6 moves repeatedly, and the cleaning brush 7 cleans the first filter plate 5. After cleaning, the second filter plate 6 is tilted by the adjustment structure to prevent impurities from accumulating on top of the second filter plate 6. The second filter plate 6 is then moved up above the water surface by the adjustment structure, rotated to a horizontal position by the adjustment structure, and then moved down to the initial height by the adjustment structure. The second filter plate 6 stores and collects impurities below the first filter plate 5, preventing impurities filtered by the first filter plate 5 from affecting the subsequent filtration effect of the first filter plate 5. The collection and summarization of impurities filtered by the first filter plate 5 can be achieved without stopping the machine, ensuring the filtration effect while improving the filtration efficiency.
[0019] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjustment structure includes a hydraulic telescopic rod 9 fixedly installed on the cover 2. The hydraulic telescopic rod 9 is located outside the filter box 1. A lifting frame 8 passes through the cover 2, and the telescopic end of the hydraulic telescopic rod 9 is fixedly connected to the lifting frame 8. A rotator for driving the second filter plate 6 to rotate is installed at the bottom of the lifting frame 8. The rotator includes two control boxes 10 fixedly installed at the bottom of the lifting frame 8. The control box 10 has a cylindrical structure. The two sides of the second filter plate 6 are respectively provided with clearance holes 11 that are adapted to the control box 10. The control box 10 is located in the clearance holes 11. A waterproof motor 12 is fixedly connected inside the control box 10, and the output end of the waterproof motor 12 is fixedly connected to the second filter plate 6. The two sides of the second filter plate 6 are in contact with the inner wall of the filter box 1. The lifting frame 8 is driven to move vertically by the hydraulic telescopic rod 9. The lifting frame 8 can then drive the second filter plate 6 to move vertically by the control box 10 and the waterproof motor 12. The second filter plate 6 and the cleaning brush 7 are rotated by the waterproof motor 12, thereby changing the tilt angle of the second filter plate 6.
[0020] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, a drain pipe 13 is fixedly connected to the bottom of the filter box 1, and the drain pipe 13 is located below the second filter plate 6.

The filter box 1 is connected to the fixed frame 15 by a tension spring 20; the filter box 1 is supported by the support leg 14. When it is necessary to clean the impurities located below the second filter plate 6, the valve on the discharge pipe 13 is opened, and the wastewater and impurities can be discharged through the discharge pipe 13. The operator drives the fixed plate 19 and the insertion rod 17 to move, and the tension spring 20 is in a stretched state so that the insertion rod 17 is disengaged from the limit sleeve 18. The insertion rod 17 and the fixed frame 15 can move upward relative to the positioning plate 16 and the filter box 1. The operator drives the box cover 2 and the fixed frame 15 to move upward so that the fixed frame 15 is disengaged from the positioning plate 16, the fixing of the box cover 2 is released, and the second filter plate 6 and the cleaning brush 7 located below the box cover 2 can be pulled out from the filter box 1.
