Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically a rotary microfiber membrane filter. Background Technology

[0002] Currently, most common filtration equipment uses wound filter cartridges, which are made by winding textile fiber yarns onto a porous skeleton. By controlling the winding density of the filter layer and the shape and structure of the filter pores, filter cartridges with different filtration precisions can be made. They can effectively remove suspended solids and particles from liquids, withstand high filtration pressures, have excellent deep filtration effects, good compatibility and high filter cake load capacity, and can be made of various materials to meet the needs of various liquid filtration.

[0003] Chinese patent CN208975309U discloses a filtration device for a rotary microfiber membrane filter. It filters wastewater through a filter plate. After passing through the filter plate, the wastewater enters the interior of the central drum through the filter support. This invention can increase the filtration area, increase the filtration speed, reduce production difficulty and cost, and simplify the assembly process.

[0004] While the above-mentioned solutions achieve faster filtration speeds through the cooperation of the filter plate and the central rotating drum, the filter plate becomes clogged with suspended debris after prolonged use, reducing water flow and impacting filtration efficiency. Therefore, we provide a rotary microfiber membrane filter to address these issues. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-4As shown, this utility model provides a technical solution: a rotary microfiber membrane filter, including a tank body 1, a filter assembly, a cleaning assembly, a liquid supply assembly, a rotating assembly, and a sludge discharge assembly.

[0032] The pool body 1 can be constructed using a combination of bricks and concrete, or assembled using welded steel plates. Inside the pool body 1, there are sequentially arranged inlets: an inlet weir 2, a filter pool 3, a filtered water weir 4, and an auxiliary equipment installation platform 5. The inlet weir 2 has an inlet 6, and it connects to the filter pool 3 via the inlet 6. The water to be filtered enters the filter pool 3 through the inlet 6. An inlet weir plate 7 is fixedly connected to the inner wall of the filter pool 3, covering the inlet 6. This weir plate buffers and distributes the water entering through the inlet 6, preventing the incoming water from directly impacting the equipment body and thus damaging or displacing it. A tilting weir plate 9 is fixedly connected to the filtered water weir 4. The tilting weir plate 9 divides the filtered water in the filtered water weir 4 into two states: one that can be directly discharged, and the other that is blocked by the tilting weir plate 9 and retained in the filtered water weir 4, providing purified water for the liquid supply components.

[0033] The filtration assembly includes a central drum 11 rotatably connected to the filter tank 3. The central drum 11 is hollow inside. An outlet 8 is provided in the filtered water weir 4. One end of the central drum 11 is connected to the filtered water weir 4 through the outlet 8. Filter discs 13 are fixedly connected to the central drum 11 at equal intervals. Water entering the filter tank 3 will be filtered by the filter discs 13. The filtered water will enter the central drum 11 through the guide groove on the filter disc 13 and then be discharged into the filtered water weir 4 through the opening on the central drum 11.

[0034] The cleaning assembly includes a collecting pipe 25 disposed within the filter tank 3 and a shield 21 vertically disposed on both sides of the filter disc 13. A spray bar 19 is disposed inside the shield 21, and the shield 21 is mounted on the spray bar 19. The shield 21 protects the spray bar 19 and can also be designed with bristles to improve cleaning effectiveness. Spray holes 20 are provided on the spray bar 19. A collection box 22 is disposed below the shield 21, and a drain pipe 23 is fixedly connected to the collection box 22. One end of the drain pipe 23 is fixed... The collection box 22 is fixedly connected to the collection pipe 25, and a support rod 24 is fixedly connected to it. One end of the support rod 24 is fixedly connected to the inner wall of the filter tank 3. After the water sprayed from the spray bar 19 through the spray hole 20 cleans the filter plate 13, the wastewater generated will drip directly into the collection box 22 instead of remaining inside the shield 21, so as to avoid the shield 21 from being blocked by debris and affecting the cleaning effect. The wastewater is then discharged into the collection pipe 25 through the drain pipe 23 on the collection box 22 for centralized discharge.

[0035] The liquid supply assembly is installed inside the tank 1. The liquid supply assembly supplies water to the spray bar 19 to complete the spray cleaning of the filter disc 13. The liquid supply assembly includes a water pump 14 installed in the auxiliary equipment installation platform 5. The input end of the water pump 14 is equipped with a backwash water inlet pipe 15, and one end of the backwash water inlet pipe 15 passes through the auxiliary equipment installation platform 5 and extends into the filtered water weir 4. The output end of the water pump 14 is equipped with a backwash water outlet pipe 16, and a pressure gauge is installed on the backwash water outlet pipe 16. When it is necessary to clean the filter disc 13 in the filter tank 3, the clean water in the filtered water weir 4 is transported to the backwash water outlet pipe 16 through the backwash water inlet pipe 15 on the water pump 14, and the water pressure can be detected by the pressure gauge on the backwash water outlet pipe 16.

[0036] Backwash water outlet pipe 16 is fixedly connected to backwash water distribution pipes 17 arranged at equal intervals. Backwash water distribution pipes 17 are fixedly connected to backwash water delivery pipes 18, and one end of backwash water delivery pipe 18 is fixedly connected to spray bar 19. Pressurized water in backwash water outlet pipe 16 is delivered to spray bar 19 through backwash water distribution pipes 17 and backwash water delivery pipes 18, and sprayed onto filter disc 13 through spray holes 20 to complete cleaning. In addition, backwash water distribution pipes 17 are also designed with electrically controlled valves, which can open each backwash water distribution pipe 17 in groups according to the needs of backwashing, so as to realize the function of group cleaning of filter disc 13.

[0037] The rotating assembly is located inside the filter tank 3 and is used to rotate the central drum 11 to complete the thorough cleaning of the filter disc 13. The rotating assembly includes a housing 10 installed inside the filter tank 3. A motor 12 is installed on the housing 10. Both the output shaft of the motor 12 and the central drum 11 are equipped with sprockets, and the two sprockets are connected by chain drive.

[0038] When cleaning the filter disc 13, the output shaft of the motor 12 can be rotated, and the central drum 11 can be rotated by the action of the chain and sprocket, and the spray bar 19 can be used to thoroughly clean the filter disc 13.

[0039] The sludge removal assembly is installed inside the tank body 1 and is used to clean the sludge accumulated on the bottom wall of the filter tank 3. The sludge removal assembly includes a sludge removal pump 26 installed in the auxiliary equipment installation platform 5 and a bottom perforated sludge removal pipe. The input end of the sludge removal pump 26 is equipped with a sludge suction pipe 27. The bottom perforated sludge removal pipe is installed inside the filter tank 3, and one end of the sludge suction pipe 27 passes through the auxiliary equipment installation platform 5 and is connected to the bottom perforated sludge removal pipe, so that the sludge suction pipe 27 on the sludge removal pump 26 cleans the sludge at the bottom of the filter tank 3 through the bottom perforated sludge removal pipe.
