[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution for a filtering device for industrial wastewater treatment: including a filtering component 1, the filtering component 1 is connected to both a cover component 2 and a plugging component 3, and the cover component 2 is connected to a motor 4;

[0028] The filtering component 1 includes a filtering pipe 11, the filtering pipe 11 is fixedly connected to a support 5, both ends of the filtering pipe 11 are fixedly connected to two first flanges 12 respectively, and a dividing ring 13 is fixedly connected inside the filtering pipe 11.

[0029] The left and right side surfaces of the dividing ring 13 are respectively fixedly connected to two ring column meshes 14, and a fixing plate 15 is fixedly connected between the inside of the dividing ring 13. The fixing plate 15 is rotationally connected to a first rotating shaft 16 through a bearing.

[0030] The first rotating shaft 16 is fixedly connected to two first rotating plates 17 inside the ring column mesh 14 on the left side. Two inner scraping plates 18 are fixedly connected at both ends between the two first rotating plates 17. The two inner scraping plates 18 are arranged in a ring-shaped rotation with a 30° offset at the left and right ends. Both inner scraping plates 18 are in contact with the inner wall of the ring column mesh 14 on the left side. By driving the second rotating shaft 24 on the cover component 2 to rotate through the motor 4, the second rotating shaft 24 drives the first transmission plate 25 to rotate synchronously, so that the first transmission plate 25 is sleeved in the sleeve hole to drive the first rotating shaft 16 to rotate. The first rotating shaft 16 drives the two first rotating plates 17 to rotate synchronously, so that the two first rotating plates 17 drive the two inner scraping plates 18 to rotate on the inner surface of the ring column mesh 14 on the left side to scrape off the filter residue. Then, as the inner scraping plates 18 rotate, the scraped filter residue is driven towards the cover component 2, so as to facilitate discharging the filter residue through the fine discharge pipe 26.

[0031] A sealing plate is fixedly connected to the right end of the ring column mesh 14 on the right side, and the sealing plate is rotationally connected to the first rotating shaft 16 through a bearing. Sleeve holes are formed on both side surfaces of the two ends of the first rotating shaft 16. The first rotating shaft 16 is fixedly connected to a second rotating plate 111 on the right side of the sealing plate.

[0032] The second rotating plate 111 is fixedly connected to an outer scraping plate 112. The outer scraping plate 112 is located inside the filtering pipe 11 and is in contact with the outer wall surface of the ring column mesh 14. The outer scraping plate 112 is arranged in a ring-shaped rotation with a 30° offset at the left and right ends. The first rotating shaft 16 can drive the second rotating plate 111 to rotate synchronously, so that the second rotating plate 111 drives the outer scraping plate 112 to rotate to scrape off the filter residue filtered on the outer surface of the ring column mesh 14 on the right side. At the same time, with the driving of the rotation of the outer scraping plate 112, the scraped filter residue is driven towards the plugging component 3, so as to facilitate discharging through the thick discharge pipe 34. In this way, the device can continuously filter and operate industrial wastewater.

[0033] The filter tube 11 is provided with a liquid inlet pipe 19 and a liquid outlet pipe 110. The liquid inlet pipe 19 corresponds to the middle of the ring column net 14 on the right, and the liquid outlet pipe 110 corresponds to the middle of the ring column net 14 on the left. The industrial wastewater is transported to the filter tube 11 through the liquid inlet pipe 19, so that the ring column net 14 on the right filters the larger impurities mixed in the wastewater and intercepts them on the outer surface. At the same time, the wastewater passes through the ring column net 14 on the right and enters the ring column net 14 on the left through the dividing ring 13, so that the ring column net 14 with a larger mesh number on the left filters the filtered wastewater again, so that the impurities are filtered and intercepted on the inner surface of the ring column net 14 on the left, and at the same time, the wastewater filtered by the ring column net 14 on the left is discharged through the liquid outlet pipe 110.

[0034] The sealing cover assembly 2 includes a sealing cover 21, which is fixedly connected to the second flange 22, and the second flange 22 is bolted to the first flange 12 on the left side, so that the sealing cover assembly 2 can be disassembled and separated from the filter assembly 1 by releasing the bolts. The sealing cover 21 is fixedly connected to the mesh ring 23, and the mesh ring 23 is socketed with the left end of the ring column mesh 14 on the left side.

[0035] The cover 21 is rotatably connected to the second rotating shaft 24 through a bearing. The left end of the second rotating shaft 24 is transmission-connected to the output shaft of the motor 4 through a transmission belt. The right end of the second rotating shaft 24 is fixedly connected to the first transmission plate 25. The first transmission plate 25 is sleeved with the sleeve hole on the left side. A row of capillary tubes 26 is provided on the cover 21.

[0036] The plugging assembly 3 includes a plugging cover 31, which is fixedly connected to the third flange 32, and the third flange 32 is bolted to the first flange 12 on the right side, so that the plugging assembly 3 can be disassembled and separated from the filter assembly 1 by releasing the bolts. The plugging cover 31 is rotatably connected to the second transmission plate 33 through a bearing, and the second transmission plate 33 is sleeved with the sleeve hole on the right side. A thick discharge pipe 34 is provided on the plugging cover 31.

[0037] The mesh number of the left ring column net 14 is set to 4 times that of the right ring column net 14, so that the right ring column net 14 can filter and intercept larger particles of impurities in the wastewater, and then the left ring column net 14 can filter the filtered wastewater again, thereby improving the filtering effect of industrial wastewater and meeting environmental protection requirements.

[0038] The operating steps of the utility model are:

[0039] The industrial wastewater is transported to the filter tube 11 through the liquid inlet pipe 19, so that the right side annular column net 14 filters and intercepts the larger impurities mixed in the wastewater on the outer surface, and at the same time, it passes through the right side annular column net 14 through the dividing ring 13 and enters the left side annular column net 14, so that the left side annular column net 14 with a larger mesh number filters the filtered wastewater again, so that the impurities are filtered and intercepted on the inner surface of the left side annular column net 14, and at the same time, the wastewater filtered by the left side annular column net 14 is discharged through the liquid outlet pipe 110;

[0040] When filtering through the two annular columnar meshes 14, the motor 4 drives the second rotating shaft 24 on the cover assembly 2 to rotate. The second rotating shaft 24 drives the first transmission plate 25 to rotate synchronously, so that the first transmission plate 25 is sleeved in the sleeve hole to drive the first rotating shaft 16 to rotate. The first rotating shaft 16 drives the two first rotating plates 17 to rotate synchronously, so that the two first rotating plates 17 drive the two inner scraping plates 18 to rotate on the inner surface of the left annular columnar mesh 14 to scrape off the filter residue. Then, as the inner scraping plates 18 rotate, the scraped filter residue is driven towards the cover assembly 2, so as to facilitate the discharge of the filter residue through the fine discharge pipe 26;

[0041] At the same time, the first rotating shaft 16 drives the second rotating plate 111 to rotate synchronously, so that the second rotating plate 111 drives the outer scraping plate 112 to rotate to scrape off the filter residue filtered on the outer surface of the right annular columnar mesh 14. At the same time, as the outer scraping plate 112 rotates, the scraped filter residue is driven towards the blocking assembly 3, so as to facilitate the discharge through the thick discharge pipe 34. In this way, the device can continuously filter industrial wastewater.
