Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to an internal inflow membrane grille cleaning device. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. An internal inflow membrane grille cleaning device is used in sewage treatment.

[0003] After retrieval, the publication number is CN217489879U, and the name is an internal cleaning device for a membrane grille, which includes a frame for assembling various components and a rotating nozzle mechanism. Through research and analysis, it is found that the device uses double nozzles and rotates the nozzles for cleaning through a rotary joint, greatly increasing the cleaning area and the slag removal amount of the cleaning device; a protection device is added at the rotating nozzle to prevent fiber winding of the rotating device during equipment operation and prevent possible personnel safety problems during maintenance; the nozzle module uses a lead screw and a guide rail slider for transmission, and the nozzle module runs more stably during left-right operation, reducing subsequent maintenance caused by operation jitter. However, to a certain extent, there are still the following disadvantages.

[0004] For example, when the device is in use, it cannot clean the inner side of the grille component. A large amount of garbage and particulate matter will accumulate on the inner side of the grille component. The flushing device installed on the device itself is fixed flushing and will only flush when the grille component is running. The flushing efficiency is not high. At the same time, long-term operation will also cause the aperture to be blocked by particulate matter, resulting in poor water passage of the grille component. In addition, a small amount of grease in the sewage will cause an oil film to form on the surface of the grille component. Coupled with the blockage of particulate matter, it will greatly affect the water passage efficiency of the grille component, resulting in untimely water supply to the subsequent equipment. To solve the above technical problems, we have designed an internal inflow membrane grille cleaning device. Content of the Utility Model

An inner cleaning mechanism 13 is arranged inside the frame 1 and located on the inner side of the membrane grille plate 4. The outer cleaning mechanism 6 includes movable rotating plates 15. The number of the movable rotating plates 15 is two. The movable rotating plates 15 are fixedly installed on the surface of the frame 1 through rotating shafts. A first connecting frame 16 is fixedly installed on the opposite side of the two movable rotating plates 15. A first flushing plate 17 is fixedly installed on the rear side of the first connecting frame 16. The inner cleaning mechanism 13 includes a fixing plate 25. The fixing plate 25 is fixedly installed on both sides of the frame 1. A fixing plate 25 is fixedly installed on the opposite side of the two fixing plates 25. A second flushing plate 27 is fixedly installed on the rear side of the fixing plate 25.

[0021] In some embodiments, as Figure 2 shown, a three-way valve 11 is connected to the left side of the liquid storage tank 2. Both ends of the three-way valve 11 are respectively connected to a telescopic hose 10 and a connecting pipe 12.

[0022] In some embodiments, as Figure 3 and Figure 4 shown, fixing frames 19 are fixedly connected to the front sides of both the first connecting frame 16 and the second connecting frame 26. A motor 20 is fixedly installed on the right side of the fixing frame 19. The output end of the motor 20 penetrates into the inner cavity of the fixing frame 19 and is fixedly connected to a connecting rotating shaft 21. Second bevel gears 23 are respectively installed through the front sides of both the first connecting frame 16 and the second connecting frame 26. The rear ends of the second bevel gears 23 respectively penetrate into the inner cavities of the first connecting frame 16 and the second connecting frame 26 and are fixedly connected to brush discs 24. A first bevel gear 22 is fixedly sleeved on the surface of the connecting rotating shaft 21. The first bevel gear 22 meshes with the second bevel gear 23.

[0023] In some embodiments, as Figure 3 shown, a push rod 18 is fixedly connected to the opposite side of the two movable rotating plates 15. Water supply valves 14 are respectively connected to the left sides of both the second flushing plate 27 and the first flushing plate 17. The water inlet ends of the water supply valves 14 are connected to a water supply device. The bottoms of both the telescopic hose 10 and the connecting pipe 12 are connected to the water supply valves 14.

[0024] In some embodiments, as Figure 2 shown, an outer sewage discharge pipe 8 is fixedly connected to the rear side of the frame 1. An inner sewage discharge pipe 7 is fixedly installed in the inner cavity of the frame 1. A connecting pipe 9 is connected to the right side of the outer sewage discharge pipe 8. The bottom of the connecting pipe 9 is connected to the inner sewage discharge pipe 7.

[0025] In some embodiments, as Figure 1and Figure 2 As shown, a liquid adding pipe is connected to the top of the liquid storage tank 2, a drain valve is connected to the right side of the liquid storage tank 2, and an observation mirror is inlaid and installed on the front of the liquid storage tank 2.

[0026] In some embodiments, by setting the push rod 18, it is convenient to push the convex plate 5 to lift the movable rotating plate 15, and it is also convenient for the movable rotating plate 15 to drive the first connecting frame 16 to move. Through the cooperation of the outer sewage discharge pipe 8 and the inner sewage discharge pipe 7, the dirt after cleaning can be centrally transported. By setting the connecting pipe 9, it is convenient for the outer sewage discharge pipe 8 to communicate with the inner sewage discharge pipe 7. By setting the observation mirror, it is convenient for the user to check the inside of the liquid storage tank 2 so as to check the remaining amount of the acidic cleaner.

[0027] In some embodiments, the pushing convex plate 5 in the device can lift the push rod 18. When the push rod 18 moves, it will lift the movable rotating plate 15, so that the movable rotating plate 15 can lift the brush disk 24 through the first connecting frame 16, so that the brush disk 24 can better fit the membrane grid plate 4.

[0028] The cleaning effect of the device is good: the motor 20 drives the first bevel gear 22 to rotate through the connecting rotating shaft 21, and then the first bevel gear 22 drives the brush disk 24 to brush the surface of the membrane grid plate 4 through the second bevel gear 23, so as to increase the cleaning effect of the device on dirt.

[0029] In actual use, the user first adds the acidic cleaner into the liquid storage tank 2 through the liquid adding pipe. During the use process, the driving machine body 3 will drive the membrane grid plate 4 to treat the sewage. During the treatment, the water supply device will transport the water liquid into the water conveying valve 14, so that the water conveying valve 14 can transport the water liquid into the first flushing plate 17 and the second flushing plate 27, so that the first flushing plate 17 and the second flushing plate 27 can cooperate to clean the inside and outside of the membrane grid plate 4. During the cleaning, the user starts the motor 20, and then the output end of the motor 20 drives the first bevel gear 22 to rotate through the connecting rotating shaft 21. Subsequently, the first bevel gear 22 drives the brush disk 24 to brush the inside and outside of the membrane grid plate 4 by meshing with the second bevel gear 23. During the cleaning, if there is too much dirt, the user can open the three-way valve 11, and then the connecting pipe 12 and the telescopic hose 10 will transport the acidic cleaner, so that the acidic cleaner can enter the water conveying valve 14 to remove the stubborn dirt on the surface of the membrane grid plate 4. And when the membrane grid plate 4 rotates, the pushing convex plate 5 will push the push rod 18, and then the push rod 18 will lift the first connecting frame 16 through the movable rotating plate 15, so that the first connecting frame 16 can drive the brush disk 24 to move out of the previous grid. After the pushing convex plate 5 moves away from the push rod 18, the brush disk 24 will fall into the next grid, so that the brush disk 24 can fit more closely with the membrane grid plate 4.
