Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane cleaning, in particular to an MBR membrane component capable of being cleaned off-line. Background Art

[0002] The MBR membrane assembly needs to be cleaned after being used for a long time. This is because the particles in the sewage cause the MBR membrane to be blocked. If it is not cleaned, its filtration performance will be affected.

[0003] Chinese patent publication number CN220223817U discloses a device for cleaning MBR membrane leachate treatment, which is used for lifting the MBR membrane group after being immersed in the MBR membrane pool. The device includes a support seat, a support rod, a rotating member, a support plate, a lifting assembly and a limit member; the support seat is arranged at the edge of the MBR membrane pool; one end of the support rod is connected to the support seat through a rotating member; the support plate is connected to the rotating member, and the rotating member is used to drive the support plate to rotate between the support seat and the support rod; the lifting assembly is connected to the other end of the support rod, and the lifting assembly is used to lift the MBR membrane group; the limit member is arranged on the side walls of the support rod and the rotating member, and the limit member is used to limit the rotation of the rotating member.

[0004] In the above patent, after the lifting assembly lifts the MBR membrane group to a height exceeding the rotating part, the bolts are loosened until the bolts and the second nut are disengaged. At this time, the rotating part can be rotated, and the support plate is rotated to the bottom of the MBR membrane group. The lifting assembly places the MBR membrane group on the support plate, and the support plate supports the MBR membrane group. Then the bolts are tightened, and the bolts pass through the first nut and the second nut. At this time, the rotating part is limited by the bolts, and the support part can no longer rotate left and right. The MBR membrane group will not shake when being washed by a high-pressure water gun on the support plate, thereby reducing safety hazards and making the washing effect of the high-pressure water gun better.

[0005] However, the effect of flushing only by a high-pressure water gun is not good, so it is necessary to provide an MBR membrane component that is easy to clean offline so that it can be lifted out of the MBR membrane pool and placed in a cleaning pool for chemical cleaning. Utility Model Content

[0006] The utility model solves the problems in the related technology and proposes an MBR membrane assembly that can be cleaned offline. The membrane assembly can be lifted out of the membrane pool by removing the anti-floating tube pressed on the top of the membrane assembly and hooking the lifting chain on the membrane assembly with a lifting hook. After cleaning, the membrane assembly is slid into the pool along the guide rod and the anti-floating tube is installed to realize offline cleaning, which greatly reduces the cleaning time and does not affect the overall wastewater treatment.

[0007] In order to solve the above technical problems, the utility model is implemented through the following technical scheme: an MBR membrane assembly that can be cleaned offline, comprising an MBR membrane assembly and a hanging assembly, wherein the MBR membrane assembly is slidably mounted on a guide rod, an anti-floating pipe is detachably mounted on the MBR membrane assembly, one end of the anti-floating pipe is fixed to the inner wall of the MBR membrane pool through a fixed bracket; the MBR membrane assembly is connected to one end of a hanging chain, and the other end of the hanging chain is connected to the fixed bracket; the hanging assembly is located above the MBR membrane pool.

[0008] As a preferred solution, a plurality of guide grooves are installed on both sides of the MBR membrane assembly, and the MBR membrane assembly is slidably connected to the guide rods through the guide grooves.

[0009] As a preferred solution, one end of the anti-floating pipe is sleeved on the fixed pipe on one side of the MBR membrane assembly, and the other end is detachably mounted on the fixed bracket through an L-shaped plate and bolts, and the fixed bracket is fixed to the inner wall of the MBR membrane pool.

[0010] As a preferred solution, a plurality of lifting ears are provided on both sides of the MBR membrane assembly, one end of the lifting chain is installed on the lifting ear, and the other end of the lifting chain is installed on the fixed bracket through a shackle.

[0011] As a preferred solution, the MBR membrane assembly includes a water production pipe, and the water production ports on both sides of the MBR membrane assembly are connected to the water production pipe through flanges.

[0012] As a preferred solution, the MBR membrane assembly further comprises an aeration tube, and the aeration tube is detachably mounted on the aeration bracket.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model removes the anti-floating tube pressed on the top of the membrane assembly, and uses a hook to hook the lifting chain on the membrane assembly to lift the membrane assembly out of the membrane pool. After cleaning, it slides into the pool along the guide rod, and then installs the anti-floating tube to achieve offline cleaning, which greatly reduces the cleaning time and does not affect the overall wastewater treatment.

An anti-floating pipe 4 is detachably installed on the MBR membrane assembly 1, and one end of the anti-floating pipe 4 is fixed to the inner wall of the MBR membrane pool 7 through a fixed bracket 6. This is because the MBR membrane assembly 1 is slidably connected to the guide rod 2. If the anti-floating pipe 4 is not installed, the MBR membrane assembly 1 is easy to float in the liquid, affecting the treatment effect, and the anti-floating pipe 4 needs to be removed when the MBR membrane assembly 1 is lifted; the MBR membrane assembly 1 is connected to one end of a lifting chain 8, and the other end of the lifting chain 8 is connected to the fixed bracket 6; the lifting assembly is located above the MBR membrane pool 7, and the lifting assembly adopts a crane equipped with a lifting hoist. When lifting, the lifting chain 8 is hung on the hook of the lifting hoist.

[0028] In one embodiment, a plurality of guide grooves 3 are installed on both sides of the MBR membrane assembly 1 , and the MBR membrane assembly 1 is slidably connected to the guide rod 2 through the guide grooves 3 .

Specifically, mounting blocks 10 are welded on both sides of the MBR membrane assembly 1, and the fixed tube 9 is vertically welded on the mounting block 10. The inner diameter of the fixed tube 9 is slightly smaller than the inner diameter of the anti-floating tube 4. The anti-floating tube 4 can be sleeved on the outside of the fixed tube 9 and the end thereof is against the mounting block 10. The other end of the anti-floating tube 4 is detachably mounted on the fixed bracket 6 by an L-shaped plate 5 and bolts, and the fixed bracket is fixed to the inner wall of the MBR membrane pool 7, so as to facilitate disassembly and assembly.

When lifting, the shackle 12 is opened, then hung on the hook, and then the shackle 12 is tightened.

[0031] In one embodiment, the MBR membrane assembly 1 includes a water production pipe 13, and the water production ports on both sides of the MBR membrane assembly 1 are connected to the water production pipe 13 through flanges.

[0032] In one embodiment, the MBR membrane assembly 1 further comprises an aeration pipe 14 , which is detachably mounted on an aeration bracket, and the aeration bracket is fixed to the bottom of the MBR membrane tank 7 by bolts.

[0033] The working process is as follows:

[0034] When cleaning, the aeration fan is stopped, the cleaning tank 15 is injected with liquid medicine, and then the flange of the water production pipe 13 on the top of the MBR membrane tank 7 is removed, and then the anti-floating pipe 4 is disassembled. When preparing for lifting, the flange of the disassembled water production pipe 13 and the lifting chain 8 need to be fixed with a rope or chain to prevent the water production pipe 13 from drooping and swinging and damaging the MBR membrane assembly 1. Then the shackle 12 is opened and hung on the hook, and then the shackle 12 is tightened and lifted by a crane.
