Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of MBR flat sheet membrane cleaning equipment, and specifically relates to an MBR flat sheet membrane cleaning device. Background Technology
[0002] MBR (Membrane Bio-Reactor) is a water treatment technology that uses membrane separation to replace the secondary sedimentation tank in the traditional activated sludge process. After a period of use, MBR membrane modules (such as MBR flat sheet membranes) may experience sludge compaction and blockage due to the accumulation of impurities, leading to membrane pore clogging. This can affect water filtration efficiency and even cause the entire MBR membrane module to fail. Membrane pore clogging also severely impacts the filtration performance of the MBR membrane module, increases treatment costs, and may even necessitate the replacement of the entire membrane module, resulting in resource waste.
[0003] Currently, the existing technology usually involves workers manually cleaning the MBR flat sheet membrane using a nozzle. This method is not only inefficient but also results in uneven cleaning. Utility Model Content
[0004] The purpose of this invention is to provide an MBR flat sheet membrane cleaning device to solve the problem of low cleaning efficiency in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] In a first aspect, this utility model provides an MBR flat membrane cleaning device, including a first scraper, a second scraper, and a housing;
[0007] A first scraper and a second scraper are arranged in parallel relative to each other above the box body by several fixing parts. A gap is formed between the first scraper and the second scraper, which is the channel for the MBR flat membrane to slide up and down.
[0008] The interior of the housing contains several high-pressure nozzles, and the exterior of the housing is equipped with quick-connect fittings that connect to the high-pressure nozzles.
[0009] A further improvement of this invention is that all of the high-pressure nozzles are adjustable-angle nozzles.
[0010] A further improvement of this invention is that all of the high-pressure nozzles are stainless steel high-pressure nozzles.
[0011] A further improvement of this utility model is that the box body is a square box body.
[0012] A further improvement of this utility model is that the box body is a polyvinyl chloride box body.
[0013] A further improvement of this utility model is that the quick-connect connector is a straight-through quick-connect connector.
[0014] A further improvement of this utility model is that the quick-connect connector is a stainless steel quick-connect connector.
[0015] A further improvement of this invention is that both the first scraper and the second scraper are silicone plates.
[0016] A further improvement of this utility model is that both the first scraper and the second scraper are straight strip scrapers.
[0017] A further improvement of this utility model is that all of the fixing components are screws.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] Compared with existing MBR flat sheet membrane cleaning devices, the MBR flat sheet membrane cleaning device proposed in this invention has two advantages. First, after the first and second scrapers initially clean the sludge on the surface of the MBR flat sheet membrane, several high-pressure nozzles are used for deep cleaning. The high-pressure nozzles have powerful jetting force, ensuring the cleaning effect. Second, the external casing is equipped with quick-connect couplings, which are plug-and-play and more convenient to operate than traditional flange connections. They can quickly connect to the high-pressure nozzles, thereby improving the cleaning efficiency of the MBR flat sheet membrane and effectively solving the problem of low cleaning efficiency in existing technologies.
[0020] Furthermore, this utility model also discloses that several high-pressure nozzles are adjustable-angle nozzles. It can be seen that this utility model can adjust the angle of several high-pressure nozzles according to actual cleaning needs, thereby ensuring that several high-pressure nozzles can directly impact the area to be cleaned, reducing ineffective spraying, and thus improving the cleaning efficiency of MBR flat sheet membranes.
[0021] Furthermore, this utility model also discloses several high-pressure nozzles, all of which are stainless steel high-pressure nozzles. Stainless steel high-pressure nozzles have good wear resistance, which makes it less likely for the high-pressure nozzles to wear or be damaged during long-term use.
[0022] Furthermore, this utility model also discloses that the box body is a square box body with four right angles, which facilitates installation and maintenance.
[0023] Furthermore, this utility model also discloses that the box body is a polyvinyl chloride box body. The polyvinyl chloride box body is not only strong, but also has good wear resistance and can resist the impact and wear in daily use.
[0024] Furthermore, this utility model also discloses that the quick-connect connector is a straight-through quick-connect connector. The straight-through quick-connect connector has a relatively simple structure, no complicated internal parts, and is easy to clean and maintain.
[0025] Furthermore, this utility model also discloses that the quick-connect connector is a stainless steel quick-connect connector. The stainless steel quick-connect connector is not only strong, but also has good wear resistance. It can remain stable under extreme temperature and pressure conditions and is not prone to deformation or damage.
[0026] Furthermore, this utility model also discloses that both the first scraper and the second scraper are silicone plates. The surface of the silicone plates is smooth, not easily stained, and easy to clean. Moreover, the silicone plates have high tear resistance and are not easily damaged.
[0027] Furthermore, this utility model also discloses that both the first scraper and the second scraper are straight-strip scrapers. The design of the straight-strip scraper can fit more closely to the surface of the high MBR flat sheet membrane, thereby cleaning the sludge on the surface of the MBR flat sheet membrane more effectively.

[0034] This invention proposes an MBR flat sheet membrane cleaning device, which includes a first scraper, a second scraper, and a housing. The first and second scrapers are arranged parallel to each other on the top of the housing via several fixing members, forming a gap between them. This gap serves as a channel for the MBR flat sheet membrane to slide up and down. Several high-pressure nozzles are installed inside the housing, and quick-connect fittings are installed on the outside. Compared to existing technologies, this invention effectively solves the problem of low cleaning efficiency in existing technologies.

The length of the first scraper 1 and the second scraper 2 is 750 mm, and the width of the first scraper 1 and the second scraper 2 is 50 mm. A gap is formed between the first scraper 1 and the second scraper 2, which is a channel for the MBR flat membrane to slide up and down.
[0039] The interior of housing 3 is equipped with several high-pressure nozzles (in this embodiment, there are 7 high-pressure nozzles 6, with a spacing of 130 mm between two adjacent high-pressure nozzles; the number of high-pressure nozzles 6 can be adjusted according to actual needs, and the spray outlet angle of the high-pressure nozzles 6 is 25 degrees).

[0041] Several high-pressure nozzles are adjustable-angle nozzles. This invention allows for adjustment of the angles of these nozzles according to actual cleaning needs, ensuring that they directly impact the area to be cleaned, reducing ineffective spraying, and thus improving the cleaning efficiency of MBR flat sheet membranes.
[0042] Several of the high-pressure nozzles are made of stainless steel. Stainless steel high-pressure nozzles have excellent wear resistance, which prevents them from wearing out or being damaged during long-term use.

[0046] Quick-connector 4 is a stainless steel quick-connector. Stainless steel quick-connectors are not only strong but also highly wear-resistant, maintaining stability under extreme temperature and pressure conditions and are not prone to deformation or damage.
[0047] Both the first scraper 1 and the second scraper 2 are silicone sheets. The ends of both scrapers 1 and 2 are pointed.
