Description

Technical Field

[0001] This utility model relates to the field of MBR membrane frame technology, specifically a modular MBR membrane frame. Background Technology

[0002] MBR membrane frame, also known as membrane module support or membrane stack, is one of the core hardware devices in the MBR (membrane bioreactor) process. Essentially, it is a steel structural frame used to support and fix the MBR membrane elements.

[0003] A complete MBR membrane frame typically consists of the following parts: 1. Main steel frame: Typically made of 304 or 316L stainless steel, offering good strength and corrosion resistance to withstand wastewater environments and cleaning agents. This includes top and bottom water collection pipes (product water pipes), side support beams, and support rods for fixing the membrane elements. 2. MBR membrane elements: This is the "heart" of the membrane frame, the component that actually performs the filtration. They are installed in rows on the membrane frame, commonly in the form of hollow fiber membranes (like bundles of hair) or flat sheet membranes (like plates). The membrane elements are connected to the water collection pipes of the membrane frame via clamps, bolts, or quick-connect couplings.

[0004] 3. Aeration system: It consists of aeration pipes installed at the bottom of the membrane frame and a large number of aeration heads. The air bubbles generated flow upward, which produces a violent shaking and scrubbing effect on the membrane fibers, preventing sludge from depositing on the membrane surface. It is the core means of controlling membrane fouling.

[0005] 4. Pipes and Interfaces: Product Water Interface: Connected to the water collection pipe to collect and lead out the filtered clean water (product water); Aeration Interface: Connected to the aeration pipe network at the bottom and connected to the air source provided by the blower; Cleaning Interface: Used for online chemical cleaning (CEB / CIP) and connected to the chemical solution.

[0006] 5. Lifting structure: The top of the membrane frame is designed with lifting lugs or lifting holes, which facilitates the use of overhead cranes or hoists to lift the entire membrane frame for offline cleaning or maintenance.

[0007] Existing MBR membrane frames require regular cleaning of the MBR membrane panels during actual use. Since multiple MBR membrane panels are installed on the MBR membrane frame and are closely arranged together, the MBR membrane frame needs to be removed for cleaning and then reinstalled one by one after cleaning when using a water gun. This takes more time to complete the cleaning process and affects the efficiency of cleaning the MBR membrane panels. Based on this, a modular MBR membrane frame is provided. Utility Model Content

[0008] The purpose of this invention is to provide a modular MBR membrane frame in order to solve the problems mentioned above.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a modular MBR membrane frame, comprising a frame assembly consisting of a bottom frame, a top frame, and columns. The top frame is distributed above the bottom frame and is connected and fixed to the bottom frame via the columns. Three columns are provided, arranged in a triangular pattern. Two columns are symmetrically fixed to the front ends of the bottom frame and the top frame, and the other column is fixed to the rear end of the bottom frame and the top frame. The bottom frame and the top frame are fixed with fixed rails on both sides of the column at the middle of the rear end of the column. A mounting bracket assembly that slides on a fixed rail is provided between the bottom frame and the top frame. The mounting bracket assembly is used to provide positioning for the installation of MBR membrane plates. When cleaning the MBR membrane plates, the mounting bracket assembly unfolds to move adjacent MBR membrane plates away from each other, making it easier to clean the MBR membrane plates.

[0010] As a further embodiment of this utility model: the mounting bracket assembly includes a side-inverted concave bracket, a U-shaped insertion groove, and a sliding sleeve; The sliding sleeve is fixed to the rear end of the vertical part of the side-inverted concave frame. The side-inverted concave frame is distributed in the middle of the bottom frame and the top frame, and the upper and lower horizontal parts of the side-inverted concave frame are respectively attached to the lower surface of the top frame and the upper surface of the bottom frame. The sliding sleeve is horizontally slidably connected to the fixed rail. The U-shaped insertion groove is symmetrically fixed to the upper and lower ends of the horizontal part of the side-inverted concave frame. The U-shaped insertion slots, symmetrically distributed vertically, are used to provide positioning for the installation of MBR membrane panels.

[0011] As a further improvement of this utility model: the side-inverted concave frame is provided in multiple groups and is symmetrically divided into two groups with the bottom frame and the top frame, and a group of U-shaped insertion grooves are symmetrically welded and fixed in the middle of the bottom frame and the top frame.

[0012] As a further improvement of this utility model, the mounting bracket assembly also includes a guide rod and a limiting block; The guide rod is fixed to one side of a sliding sleeve and passes through another horizontally adjacent sliding sleeve; two limiting blocks are fixedly installed on the outside of one guide rod. The two limiting blocks are located on both sides of another horizontally adjacent sliding sleeve.

[0013] As a further improvement of this utility model: the guide rods on two adjacent sliding sleeves are staggered vertically, and the sliding sleeves are provided with through holes for the guide rods to pass through.

[0014] As a further embodiment of this utility model: an L-shaped connecting frame is fixed to the outer side of the outermost side-inverted concave frame. When the multiple side-inverted concave frames approach and retract, the L-shaped connecting frame fits against the side of the fixed rail and is fixedly connected to the fixed rail by bolts.

[0015] As a further improvement of this utility model: a cover plate is installed between two columns distributed at the front end of the bottom frame and the top frame, and the cover plate is used to block the port of the bottom U-shaped insertion groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are: By setting up the mounting bracket assembly, multiple MBR membrane plates can be spaced further apart, thus obtaining a larger cleaning space. After cleaning, simply push the outermost side-tilted concave bracket to move it towards the center. The overall operation is simple and convenient, and the cleaning efficiency can be effectively improved. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-5In this embodiment of the utility model, a modular MBR membrane frame includes a frame assembly 1 consisting of a bottom frame 101, a top frame 102, and columns 103. The top frame 102 is distributed above the bottom frame 101 and is connected and fixed to the bottom frame 101 through the columns 103. There are three columns 103, which are arranged in a triangular pattern. Two columns 103 are symmetrically fixed on the front sides of the bottom frame 101 and the top frame 102, and the other column 103 is fixed in the middle of the rear end of the bottom frame 101 and the top frame 102. The bottom frame 101 and the top frame 102 have fixed rails 104 on both sides of the column 103 at the middle of the rear end. A mounting frame assembly 2 is provided between the bottom frame 101 and the top frame 102 and is slidably mounted on the fixed rail 104. The mounting frame assembly 2 is used to provide positioning for the installation of MBR membrane plates. When cleaning the MBR membrane plates, the mounting frame assembly 2 is unfolded to move the two adjacent MBR membrane plates away from each other, making it easier to clean the MBR membrane plates. Mounting bracket assembly 2 includes a side-inverted concave bracket 201, a U-shaped insertion groove 202, and a sliding sleeve 203; The sliding sleeve 203 is fixed to the rear end of the vertical part of the side-inverted concave frame 201. The side-inverted concave frame 201 is distributed in the middle of the bottom frame 101 and the top frame 102, and the upper and lower horizontal parts of the side-inverted concave frame 201 are respectively attached to the lower surface of the top frame 102 and the upper surface of the bottom frame 101. The sliding sleeve 203 is horizontally slidably connected to the fixed rail 104. The U-shaped insertion groove 202 is symmetrically fixed to the upper and lower ends of the horizontal part of the side-inverted concave frame 201. The U-shaped insertion slots 202, which are symmetrically distributed vertically, are used to provide positioning for the installation of MBR membrane panels; The side-tilting concave frame 201 is provided with multiple pieces and is symmetrically divided into two groups with the bottom frame 101 and the top frame 102. A set of U-shaped insertion grooves 202 are symmetrically welded and fixed in the middle of the bottom frame 101 and the top frame 102. Mounting bracket assembly 2 also includes guide rod 204 and limit block 205; The guide rod 204 is fixed to one side of a sliding sleeve 203 and passes through another horizontally adjacent sliding sleeve 203. Two limiting blocks 205 are fixedly installed on the outside of one guide rod 204. Two limiting blocks 205 are located on both sides of another horizontally adjacent sliding sleeve 203. Through the cooperation of the guide rod 204 and the limiting blocks 205, the distance between the two adjacent sliding sleeves 203 is limited. An L-shaped connecting frame 206 is fixed to the outer side of the outermost inverted concave frame 201. When multiple inverted concave frames 201 approach each other and retract, the L-shaped connecting frame 206 fits against the side of the fixed rail 104 and is fixedly connected to the fixed rail 104 by bolts.

[0021] In this embodiment, it should be noted that the aeration system, pipes and interfaces, and lifting structure on this MBR membrane frame can adopt the conventional design of commonly available MBR membrane frames on the market. Therefore, they will not be described in detail here. In daily use, the MBR membrane plates are inserted into multiple sets of U-shaped insertion slots 202 to achieve positioning and distribution. When it is necessary to flush the MBR membrane plates, the operation method is as follows: First, disassemble each interface and corresponding pipe of frame component 1, and then lift the entire device out to the outside to facilitate cleaning operations; Next, remove the connecting bolts between the L-shaped connecting frame 206 and the fixed rail 104 to release the connection between the L-shaped connecting frame 206 and the fixed rail 104. Then, pull the L-shaped connecting frame 206 to move the outermost side-inverted concave frame 201 outward. During this process, the sliding sleeve 203 corresponding to this side-inverted concave frame 201 moves along the outer wall of the fixed rail 104. The guide rod 204 on this sliding sleeve 203 moves synchronously. When the limiting block 205 at the end of the guide rod 204 contacts another sliding sleeve 203, the movement of the first side-inverted concave frame 201 will pull the second side-inverted concave frame 201 to move synchronously. By operating in this manner, multiple side-inverted concave frames 201 can first move away from each other and then move synchronously, thereby enabling multiple MBR membrane plates to move away from each other and unfold (it should be noted that the MBR membrane plates are connected to the existing pipelines using flexible hoses, and the hoses have a certain length to provide space for the MBR membrane plates to move away from each other). This allows for a larger cleaning space and effectively improves cleaning efficiency (it should be noted that when multiple side-inverted concave frames 201 are fully unfolded, the outermost few side-inverted concave frames 201 will move out of the fixed rail 104, but will remain stable and horizontal with the cooperation and support of multiple guide rods 204). After cleaning, simply push the outermost side-tilting concave frame 201 to move it towards the center. Finally, the two adjacent sliding sleeves 203 are pressed together by the limiting block 205 in the middle of the guide rod 204, and the limiting block 205 at the end of the guide rod 204 on the second sliding sleeve 203 near the center is pressed together with the side of the rear column 103. Finally, the connection between the L-shaped connecting frame 206 and the fixed rail 104 is fixed. The overall operation is simple and convenient.

[0022] Please refer to this carefully. Figures 2-5 The guide rods 204 on two adjacent sliding sleeves 203 are staggered vertically, and the sliding sleeves 203 have through holes for the guide rods 204 to pass through.

[0023] In this embodiment, this structure ensures that the guide rods 204 on two adjacent sliding sleeves 203 do not interfere with each other.

[0024] Please refer to this carefully. Figures 1-4A cover plate 105 is installed between two columns 103 located at the front of the bottom frame 101 and the top frame 102. The cover plate 105 is used to block the port of the bottom U-shaped plug groove 202.

[0025] In this embodiment: by removing the cover plate 105, the MBR membrane plate can be disassembled and installed from the front end. After the MBR membrane plate is installed, the front end of the MBR membrane plate can be limited by the cover plate 105 to ensure stability during daily use.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
