[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process and contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater has a wide variety and complex composition. Since industrial wastewater often contains various toxic substances, it pollutes the environment and poses a great harm to human health. Therefore, comprehensive utilization should be developed to turn harm into benefit, and corresponding purification measures should be taken according to the components and concentrations of pollutants in the wastewater before it can be discharged.

[0003] A Chinese patent with the authorization announcement number CN216236358U discloses an industrial wastewater purification device, which includes a wastewater purification body. There is a feed inlet at the top of the wastewater purification body, a purification treatment chamber is arranged inside the wastewater purification body, an ozone purification part is arranged on the wastewater purification body, and the ozone purification part extends into the purification treatment chamber. A detachable anti-blocking filtering component that can reciprocate linearly in the horizontal direction is arranged in the feed inlet.

[0004] Larger solid impurities in the wastewater stay on the holes of the filter plate. When the filter plate needs to be cleaned, the pumping drive part is started to drive the filter plate to be pulled out. During the cleaning process of the filter plate, the whole device stops running, resulting in the shutdown of the production line and affecting the normal production progress. Therefore, the present application provides a multi-stage filtering industrial wastewater purification device to meet the requirements. Summary of the Utility Model

[0031] As Figures 1-6As shown in the figure, an embodiment of the present utility model provides a multi-stage filtering industrial wastewater purification device, which includes a water inlet pipe 1 and a water passing pipe 3. A cleaning mechanism 2 is arranged on one side of the water inlet pipe 1. The cleaning mechanism 2 includes a protective shell 21 and a motor one 22 fixedly installed on the protective shell 21. The output end of the motor one 22 is fixedly installed with a filter pipe 23. Both sides of the filter pipe 23 are rotationally connected to the inner wall of the protective shell 21. A feeding groove 24 is opened on the filter pipe 23. A scraping plate 25 is fixedly installed on the filter pipe 23, and the scraping plate 25 is located on one side of the feeding groove 24. The radian of the outer wall of the scraping plate 25 fits the radian of the inner wall of the protective shell 21. A feeding screw 26 is rotationally connected inside the filter pipe 23. A fixed shell 27 is fixedly installed on the protective shell 21. An outlet groove 28 is opened on the fixed shell 27. A filter plate 29 is fixedly installed on the inner wall of the water passing pipe 3. A first filtering hole 210 is opened on the filter plate 29. The radian of the outer wall of the scraping plate 25 fits the radian of one side of the filter plate 29. A motor two 211 is fixedly installed on the fixed shell 27. The output end of the motor two 211 is fixedly connected to one end of the feeding screw 26. A second filter cylinder 5 is fixedly installed on one side of the water passing pipe 3. A second filtering hole 7 is opened on the second filter cylinder 5. The rotation speed of the feeding screw 26 is greater than the rotation speed of the filter pipe 23. One end of the water inlet pipe 1 is inclined and arranged on one side of the protective shell 21. Industrial wastewater enters the inside of the protective shell 21 from one side of the water inlet pipe 1. The motor one 22 is started to drive the filter pipe 23 to rotate. The motor two 211 is started to drive the feeding screw 26 to rotate. The rotation speed of the feeding screw 26 is greater than the rotation speed of the filter pipe 23. The wastewater flows to one side of the filter plate 29. Water and impurities with smaller particles flow into the water passing pipe 3 from the first filtering hole 210.

The filter pipe 23 drives the scraping plate 25 to rotate. The outer wall of the scraping plate 25 scrapes the impurities on one side of the filter hole one 210. The impurities stay on the scraping plate 25. The water leaks out from the water draining hole two on the scraping plate 25. When the scraping plate 25 turns to the position where it is vertically upward, the impurities fall vertically downward due to the action of gravity. After entering the feeding groove 24, they fall between the blades of the feeding screw 26. The water leaks out from the interior of the water draining hole one. During the rotation of the feeding screw 26, the impurities are gradually transported into the interior of the fixed shell 27 and finally fall from the position of the discharge groove 28. After the wastewater is filtered for the first time, it enters the water pipe 3, and then flows from the water pipe 3 into the interior of the filter cartridge two 5, flows to the filter hole two 7 and is filtered between the support plates 6, and then flows from the filter hole three 8 on the outer wall of the filter cartridge one 4 into the interior of the water collecting pool 9 to complete the filtration of the wastewater.
