Existing treatment methods include adding flocculants to accelerate the sedimentation of particulate matter and filtering suspended solids and large particle impurities in wastewater through filters. In the prior art, wastewater is filtered through a filter screen. However, most of the existing filter screens are static filters, which causes a large amount of impurities to accumulate on the filtering surface of the filter screen. The accumulated impurities will block the filter holes of the filter screen, affect the water flow rate of the filter screen, and reduce the filtration efficiency of wastewater. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an efficient sewage filtration equipment for wastewater treatment.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an efficient sewage filtration equipment for wastewater treatment, including two fixed ring parts.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0019] As shown Figures 1-4 in the figure, a high-efficiency sewage filtration device for wastewater treatment includes two fixed ring members 17. A cylindrical filter screen 11 is installed between the two fixed ring members 17. A toothed ring 9 is fixedly sleeved on the surface of one of the fixed ring members 17. A gear 8 is arranged above the toothed ring 9. A transmission chain 6 is connected between the gear 8 and the toothed ring 9. A driving motor 7 is connected to the side of the gear 8. After the driving motor 7 is powered on, it drives the gear 8 to rotate. The gear 8 drives the toothed ring 9 to rotate through the transmission chain 6. When the toothed ring 9 is stressed, it drives one of the fixed ring members 17 to rotate. One of the fixed ring members 17 drives the cylindrical filter screen 11 and the other fixed ring member 17 to rotate synchronously. As the cylindrical filter screen 11 rotates, impurities will also slide on its inner surface as the cylindrical filter screen 11 rotates, reducing the number of blockages of the filter holes of the cylindrical filter screen by impurities and improving the efficiency of the cylindrical filter screen in filtering impurities in wastewater.

[0020] On one side of the two fixed ring members 17, a first mounting plate 5 and a second mounting plate 12 are respectively provided. Rotating wheels 3 are connected to the sides of the first mounting plate 5 and the second mounting plate 12 through rotating shafts. The arc surfaces of the plurality of rotating wheels 3 slide along the arc surfaces of the two fixed ring members 17 respectively. The driving motor 7 is installed on the top of the first mounting plate 5 through a motor bracket. As the two are stressed and rotate, the two fixed ring members 17 rotate synchronously on the surfaces of the plurality of rotating wheels 3. At the same time, the rotating wheels 3 rotate on the surfaces of the rotating shafts when stressed, improving the stability of the two fixed ring members 17 during the stressed rotation process.

[0021] Support seats 16 are installed on the sides of the first mounting plate 5 and the second mounting plate 12 respectively. The two support seats 16 play a role in supporting the device.

[0022] An arc plate 2 is installed between the sides of the first mounting plate 5 and the second mounting plate 12 at corresponding positions. A water outlet pipe 1 is installed through the bottom of the arc plate 2. The arc plate 2 is located below the cylindrical filter screen 11 and is used to receive the wastewater falling from the cylindrical filter screen 11. The wastewater is discharged from the water outlet pipe 1 through the arc plate 2.

[0023] A plurality of connecting rods 10 arranged at equal angles are installed between the sides of the two fixed ring members 17 at corresponding positions. The surface of the connecting rod 10 is in contact with the outside of the cylindrical filter screen 11. The connecting rod 10 is used to increase the connection stability between the two fixed ring members 17 and at the same time play a role in protecting the cylindrical filter screen 11.

[0024] A water inlet pipe 4 is installed through the side of the first mounting plate 5. One end of the water inlet pipe 4 passes through the inner hole of the fixed ring member 17 and extends into the interior of the cylindrical filter screen 11. The water inlet pipe 4 is fixedly connected to the first mounting plate 5, improving the water outlet work of the water inlet pipe 4 without being affected when the fixed ring member 17 rotates.

[0025] A through hole is formed in the side surface of the second mounting plate 12. A baffle 18 is fitted and mounted in the inner hole of the fixed ring member 17 corresponding to the position of the second mounting plate 12. An installation rod 19 is mounted on the side surface of the baffle 18. One end of the installation rod 19 passes through the through hole and extends to one side of the second mounting plate 12. A long strip 15 is mounted at one end of the installation rod 19. Two stud bolts 14 are fixedly mounted on the side surface of the second mounting plate 12. Both ends of the long strip 15 are movably sleeved on the surfaces of the two stud bolts 14. Threaded sleeves 13 are sleeved on the surfaces of the two stud bolts 14. The ends of the two threaded sleeves 13 are in contact with the side surface of the long strip 15. The other side surface of the long strip 15 is in contact with the side surface of the second mounting plate 12. Since a large amount of impurities are accumulated at the bottom inside the cylindrical filter screen 11, in order to remove the impurities in the cylindrical filter screen 11, first rotate the two threaded sleeves 13 in sequence. After the two threaded sleeves 13 are spirally removed from the two stud bolts 14, the long strip 15 can be pulled. The long strip 15 pulls the baffle 18 out of the inner hole of the fixed ring member 17 through the installation rod 19. After the baffle 18 is removed from the through hole of the second mounting plate 12, it is convenient for the staff to clean the impurities in the cylindrical filter screen 11 through the through hole and the inner hole of the fixed ring member 17.
