Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, specifically to a slice-type membrane module. Background Technology
[0002] MBR (Membrane Bioreactor), an innovative wastewater treatment method, cleverly integrates biological treatment and membrane separation technologies. This technology replaces traditional sedimentation tanks with membrane separation, efficiently separating solids and suspended matter from water. Simultaneously, the bioreactor degrades organic matter. It not only possesses highly efficient water purification capabilities but also saves space and produces highly stable effluent quality, making it widely used in various water treatment fields.
[0003] During the use of MBR membranes, membrane modules can be affected by fouling, necessitating regular cleaning and maintenance. When membrane modules experience caking or malfunction, the entire membrane stack must be lifted out of the water tank for comprehensive cleaning or maintenance. However, traditional MBR membrane stacks are large, weighing several to tens of tons, requiring heavy-duty cranes to lift the entire stack out of the water tank for cleaning. In some special areas, such as containerized water treatment equipment near roads, to avoid disrupting traffic, operations can only be carried out at night or during specific times, resulting in high difficulty, maintenance costs, and inconvenience. Therefore, there is an urgent need to design a lightweight MBR membrane module that is easy to disassemble and install, reducing maintenance difficulty and costs. Summary of the Invention
[0004] Technical Problem: To solve the above-mentioned technical problems, this utility model provides a sliced membrane module, which divides the traditional MBR membrane module into multiple sliced sub-membrane stacks, reducing the large volume and weight to a smaller volume and weight. The sub-membrane stacks can be lifted out of the water for maintenance or cleaning using manual lifting tools or a small crane. The sliced sub-membrane stacks and the base frame are fixed by magnetic attraction and use a socket-type connecting pipe, facilitating installation and removal, and making operation simple and convenient.
[0005] Technical solution: To solve the above technical problems, the technical solution adopted in this utility model embodiment is as follows:
[0006] A sliced membrane module, comprising:
[0007] The base frame has an aeration device and a base magnetic block at the bottom, and a positioning frame and a product water pipe inlet at the top. The positioning frame is located inside the base frame and is used to fix the sub-membrane stack and prevent misalignment. The product water inlet is located at the top of the base frame and is used to connect with the product water pipe of the sub-membrane stack. A product water flange is also provided at the top of the base frame.
[0008] The sub-membrane stack includes a membrane frame and membrane sheets. The membrane frame is a hollow structure that forms a passage. The membrane sheets are composed of several membrane filaments and are installed inside the membrane frame and communicate with the membrane frame. The upper part of the membrane frame is provided with a hanger and a product water pipe, and the bottom is provided with a magnetic block for magnetic fixation of the sub-membrane stack to the base frame.
[0009] Furthermore, the sub-membrane stack permeate pipe is equipped with a permeate connector, which has several O-ring mounting grooves and a corresponding number of sealing rings.
[0010] Furthermore, the diaphragm and the membrane frame are connected by a socket joint, and the tail is fixed to prevent the diaphragm from detaching from the membrane frame due to pressure during backwashing or vibration during operation.
[0011] During installation, the base frame is fixed to the membrane tank, ensuring that the permeate inlet at the top of the base frame is above the highest liquid level. The sub-membrane stack is installed within each positioning frame. During installation, the permeate pipe connector of the sub-membrane stack is inserted into the permeate inlet at the top of the base frame, and the O-ring on the connector seals against the inner wall of the inlet. The magnetic blocks at the bottom of the sub-membrane stack attract and adhere to the magnetic blocks at the bottom of the base frame, securing them with strong magnetic force. This replaces bolts or pins, making operation more convenient.
[0012] When a membrane stack needs to be dismantled for maintenance, simply hook the hook onto the lifting rod of the corresponding membrane stack and pull it out of the base frame under a certain traction force. When the permeate pipe connector of the membrane stack is pulled out from the permeate inlet at the top of the base frame, a permeate inlet plug must be used to seal the permeate inlet to ensure that the remaining membrane stacks continue to produce water. This operation does not require draining the water in the membrane tank and can be performed in situ. The dismantling of the membrane stack will not affect the continued operation of the remaining membrane stacks.
[0013] Beneficial effects: Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This utility model adopts the method of "making the large into small", which divides the entire large membrane stack into multiple sub-membrane stacks, reducing the volume and weight. The sub-membrane stacks can be lifted out of the water for maintenance or cleaning using manual lifting tools or small cranes. The operation is convenient and efficient, and it is suitable for scenarios where the working space or time is limited.
[0014] The present invention uses magnetic attraction to fix the sliced sub-membrane stack and the base frame, and uses a socket-type pipe connection method, which facilitates installation and dismantling.
[0015] This utility model allows for in-situ installation and removal without the need to drain water from the pool during operation, and does not affect the normal operation of other membrane stacks. Attached Figure Description

[0022] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.
[0023] like Figures 1-4 A slice-type membrane module includes a base frame 1 and a sub-membrane stack 2. The base frame 1 has a three-dimensional structure, and the support rods of the entire three-dimensional structure are hollow, forming a complete passage. An aeration device 3 is provided at the bottom of the base frame 1, and a base magnetic block 4 is provided on the bottom support beam of the base frame. A positioning frame 5 is provided at the top of the base frame 1. The positioning frame 5 is located inside the base frame 1 and is used to limit the position of the sub-membrane stack 2 to prevent misalignment and facilitate better installation. A permeate inlet 6 and a permeate flange 7 are provided at the top of the base frame 1. During installation, the permeate inlet 6 and the permeate flange 7 must be located above the water tank surface to prevent liquid in the water tank from flowing back into the permeate inlet when the sub-membrane stack 2 is removed. This ensures that the sub-membrane stack 2 can be lifted out of the water tank for maintenance or cleaning without changing the liquid level in the water tank.
[0024] The sub-membrane stack 2 includes a membrane frame 8 and a membrane sheet 9. The membrane sheet 9 is composed of several membrane filaments encapsulated at both ends in a membrane shell. The membrane frame 8 has a hollow structure to form a passage. The upper part of the membrane frame 8 is provided with a hanger 10 and a product water pipe 11. The membrane sheet 9 is connected and fixed to the membrane frame 8. Preferably, the membrane sheet 9 and the membrane frame 8 are connected by a socket. The product water pipe of the membrane sheet is installed in the socket of the membrane frame 8 through a socket and communicates with the internal cavity. The product water is collected through the cavity of the membrane frame 8 and then discharged through the product water pipe 11.
[0025] The bottom of the membrane frame 8 is provided with a magnetic block 13, which matches the base magnetic block on the base frame 1. It is used to magnetically fix the sub-membrane stack 1 to the base frame 2. Since there are no fasteners such as bolts involved in this fixing method, it is easy to install and remove.
[0026] The product water pipe 11 is provided with a product water connector at the product water outlet. The connector has several O-ring mounting grooves and a corresponding number of sealing rings for connecting with the product water inlet 6 on the base frame 1. When the sub-membrane stack 2 needs maintenance, the sub-membrane stack product water pipe 11 only needs to be pulled out from the product water inlet 6 to lift the individual sub-membrane stack 2 out of the membrane stack.
[0027] This invention is simple to operate and highly feasible. It not only divides the overall membrane stack into multiple modules through sub-membrane stacks, allowing for convenient and quick removal and installation of any module during cleaning, but also reduces the volume and weight of the membrane stack that needs to be removed, minimizing workspace. Sub-membrane stacks can be maintained independently, making it easy to promote and use, especially in special scenarios where operating space or time is limited.

Those skilled in the art should understand that this utility model is not limited to the specific embodiments described above. The specific embodiments and descriptions in the specification are merely for further illustrating the principles of this utility model.
