[0027] Example 1

[0028] A multi-stage filtration device for industrial water treatment, such as Figures 1 to 3 As shown, the system includes a filter box 1, a mixing box 2 fixed to the top of the filter box 1, a fixing frame 6 detachably fixed to the inner wall of the filter box 1, and a filter plate 7 fixed to the inner wall of the fixing frame 6. The filter plate 7 is conical. A collection pipe 8 located below the filter plate 7 is provided on the inner wall of the filter box 1. The collection pipe 8 includes a vertical pipe and an inclined pipe connected to each other. The top end of the vertical pipe is detachably fixed to the filter plate 7, and the inclined pipe is fixedly connected to the filter box 1, with one end extending out of the filter box 1 and inclined towards the ground. A water leakage hole is provided on the outer wall of the vertical pipe, and the inner walls of both the upper and lower ends of the vertical pipe are fixed. The filter box 1 has a closed ring 11. A telescopic rod 16 is fixed to the inner wall of the filter box 1 by a support frame. The telescopic end of the telescopic rod 16 is connected to a support rod 9. The support rod 9 is slidably engaged with the collection pipe 8. A first blocking block 12 is connected to the top of the support rod 9. The first blocking block 12 is sealed to the closed ring 11 located at the top of the vertical pipe. A second blocking block 14 is connected to the outer wall of the bottom end of the support rod 9. The second blocking block 14 is sealed to the closed ring 11 located at the bottom end of the vertical pipe. The distance between the first blocking block 12 and the second blocking block 14 is less than the distance between the two closed rings 11.

[0029] The mixing box 2 has two mixing chambers inside, and the top of each mixing chamber is connected to a water inlet pipe 3. One end of each water inlet pipe 3 is connected to the same electric three-way valve 4. The bottom of each mixing chamber is connected to the same liquid outlet pipe 20. The end of the liquid outlet pipe 20 connected to the mixing chamber is equipped with a solenoid valve. The liquid outlet of the liquid outlet pipe 20 faces the filter plate 7. A dosing port is provided at the top of the mixing chamber. A guide cone 21 is fixed on the inner wall of the filter box 1. The guide cone 21 is located directly below the liquid outlet pipe 20. Multiple purification plates 22 are provided on the inner wall of the filter box 1 below the filter plate 7. The purification plates 22 can be made of activated carbon or other materials. A water outlet 5 is provided on the bottom side wall of the filter box 1. The inner walls of the two mixing chambers are rotatably connected to the same stirring frame 19. A stirring motor that drives the stirring frame 19 to rotate is installed on the outer wall of the mixing box 2.

[0030] During operation, wastewater enters a mixing chamber through an electric three-way valve 4 and an inlet pipe 3. External dosing equipment adds chemicals through the dosing port. The stirring motor drives the stirring frame 19 to rotate, ensuring uniform mixing of the wastewater and chemicals. Then, the solenoid valve at the bottom of this mixing chamber opens, while the solenoid valve at the bottom of another mixing chamber closes. The electric three-way valve 4 changes the connection path, allowing subsequent wastewater to enter another mixing chamber for further dosing and mixing. The dosing-completed wastewater enters the filter box 1 through the outlet pipe 20, impacting the top of the guide cone 21. The outlet pipe 20 then guides the wastewater, dispersing it around the filter plate 7. The filter plate 7 filters the wastewater, trapping impurities. The impurities on the surface of the filter plate 7 converge towards the center along the outer wall of the filter plate 7 and fall into the vertical pipe of the collection pipe 8. After being purified by the purification plate 22, the filtered wastewater is discharged from the outlet 5. After a period of time, when the impurities in the collection pipe 8 reach a certain amount, the telescopic rod 16 pushes the support rod 9 to move upward. The first block 12 fits with the closing ring 11 at the upper end of the vertical pipe, so that the upper end of the vertical pipe is closed. At the same time, the second block 14 moves away from the closing ring 11 at the bottom end of the vertical pipe, and the bottom end of the vertical pipe opens, allowing the impurities to flow out of the collection pipe 8. After the impurities in the collection pipe 8 flow out, the telescopic rod 16 drives the support rod 9 to reset, the bottom end of the vertical pipe is closed, and the top end is opened, allowing the impurities to enter the collection pipe 8.

[0031] By setting up a collection pipe 8, a closed ring 11, a first blockage block 12, a toggle frame 13, a second blockage block 14, and a telescopic rod 16, impurities can be discharged to the outside while filtering, without the need to stop the machine for cleaning.

[0032] By setting up the outlet pipe 20, the wastewater is dispersed around the filter plate 7, avoiding long-term impact of wastewater on the fixed position on the surface of the filter plate 7.

[0033] Example 2

[0034] A multi-stage filtration device for industrial water treatment, this embodiment is based on embodiment 1, with the following improvements, such as... Figures 3 to 4 As shown, a hollow cylinder 10 is rotatably fitted to the outer wall of the support rod 9. A toggle frame 13 is fixed to the outer wall of the hollow cylinder 10. The side wall of the toggle frame 13 contacts the inner wall of the vertical pipe. The second blocking block 14 is slidably fitted to the outer wall of the hollow cylinder 10. The telescopic rod 16 is connected to the support rod 9 through a drive assembly 15. The drive assembly 15 includes a mounting box 17 and a drive motor 18. The mounting box 17 is fixed to the telescopic end of the telescopic rod 16. The drive motor 18 is installed on the inner wall of the mounting box 17. The bottom end of the support rod 9 is fixedly connected to the mounting box 17. The hollow cylinder 10 is rotatably fitted to the mounting box 17. The output shaft of the hollow cylinder 10 and the drive motor 18 are driven by a gear mechanism. The gear mechanism is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. The bottom end of the second blocking block 14 is fixedly connected to the outer wall of the mounting box 17 through a connecting cylinder.

[0035] While impurities are being discharged, the drive motor 18 drives the hollow cylinder 10 to rotate, which in turn drives the agitator 13 to rotate, scraping and cleaning the inner wall of the collection tube 8 to prevent the water holes from becoming clogged. At the same time, the impurities are agitated to prevent them from accumulating in the collection tube 8 and becoming difficult to discharge.

[0036] The hollow cylinder 10, the agitator 13, and the drive assembly 15 are used to scrape and clean the inner wall of the collection pipe 8 to prevent the water holes from getting clogged. At the same time, the impurities are stirred to prevent them from accumulating in the collection pipe 8 and being difficult to discharge.

[0037] Working principle: During operation, wastewater enters a mixing chamber through an electric three-way valve 4 and an inlet pipe 3. External dosing equipment adds chemicals through the dosing port. The stirring motor drives the stirring frame 19 to rotate, ensuring uniform mixing of the wastewater and chemicals. Then, the solenoid valve at the bottom of this mixing chamber opens, while the solenoid valve at the bottom of another mixing chamber closes. The electric three-way valve 4 changes the connection path, allowing subsequent wastewater to enter another mixing chamber for further dosing and mixing. The dosing-treated wastewater enters the filter box 1 through the outlet pipe 20, impacting the top of the guide cone 21. The outlet pipe 20 guides the wastewater, dispersing it around the filter plate 7. The filter plate 7 filters the wastewater, trapping impurities on its surface and converging towards the center along the outer wall of the filter plate 7, eventually falling into the vertical pipe of the collection pipe 8. The filtered wastewater then undergoes further purification. After purification by the chemical plate 22, the water is discharged from the outlet 5. After a period of time, when the impurities in the collection pipe 8 reach a certain amount, the telescopic rod 16 pushes the support rod 9 upward. The first block 12 fits with the sealing ring 11 at the upper end of the vertical pipe, thus sealing the upper end of the vertical pipe. At the same time, the second block 14 moves away from the sealing ring 11 at the bottom end of the vertical pipe, opening the bottom end of the vertical pipe and allowing the impurities to flow out of the collection pipe 8. The drive motor 18 drives the hollow cylinder 10 to rotate, causing the hollow cylinder 10 to drive the actuating frame 13 to rotate, scraping and cleaning the inner wall of the collection pipe 8 to prevent the water permeable holes from being blocked. At the same time, it agitates the impurities to prevent them from accumulating in the collection pipe 8 and being difficult to discharge. After the impurities in the collection pipe 8 flow out, the telescopic rod 16 drives the support rod 9 to reset, sealing the bottom end of the vertical pipe and opening the top end, allowing the impurities to enter the collection pipe 8.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
