Abstract
Description
Technical Field
[0001] This utility model relates to the field of MBR membrane module technology, and in particular to an MBR membrane frame module. Background Technology
[0002] MBR (Membrane Bioreactor) is a novel and highly efficient wastewater treatment process that combines high-efficiency membrane separation technology with the traditional activated sludge process. The MBR system uses a hollow fiber ultrafiltration membrane as the central treatment unit. The MBR membrane frame assembly is placed in the aeration tank. The treated liquid flows through the membrane surface at a certain velocity. Water molecules permeate through the membrane under a certain suction force, while suspended solids, colloids, macromolecular organic matter, and microorganisms are blocked, thereby achieving the purpose of purification and separation. Combined with the aeration system to introduce oxygen, the biological reaction efficiency of the MBR membrane is improved.
[0003] The frame assembly is one of the main components of an MBR system, used to support and fix membrane modules (such as hollow fiber membranes, flat sheet membranes, etc.) to ensure their efficient and stable operation during water treatment. It mainly consists of a main frame (stainless steel or engineering plastic), a membrane fixing system (water collection pipes / slots), an aeration device (piping network and diffusers), and a water collection system (product water pipelines).
[0004] The existing main frame has poor stability. After long-term use, the connections are prone to loosening and the frame is prone to deformation. After the frame is deformed, it will affect the sealing of the MBR membrane and the connection of each pipeline, which will reduce the sewage treatment capacity and make it difficult to meet the usage requirements. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the main frame of the existing MBR membrane frame assembly has poor stability, is prone to deformation, and affects the sealing of the MBR membrane and the connection of various pipelines. Therefore, this invention proposes an MBR membrane frame assembly.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An MBR membrane frame assembly includes a main frame, which comprises two symmetrically arranged main frames and four parallel water collection pipes. The two main frames are located at both ends of the water collection pipes, and the four water collection pipes are located at the four corners of the main frame. The assembly also includes: a reinforcing plate disposed at the connection between the main frame and the water collection pipes for fixing the water collection pipes to the main frame; and diagonal bracing assemblies, which are detachably connected to the reinforcing plates on the same side.
[0008] To facilitate the connection and reinforcement of the water collection pipe and the main frame, preferably, the reinforcing plate includes an inner plate with an L-shaped structure. The outer right-angled surface of the inner plate abuts against the inner wall of the main frame and the water collection pipe, respectively. An inclined plate is fixedly connected to the inner right-angled surface of the inner plate, and the inclined bracing assembly is detachably connected to the inclined plate.
[0009] To facilitate assembly and disassembly, the inner plate is further detachably connected to the inner wall of the main frame and the inner wall of the water collection pipe by means of the first screw.
[0010] To reduce the lateral deviation of the water collection pipe on the horizontal plane, a side plate is further fixedly installed on the outer wall of the inner plate. The side plate has an L-shaped structure and is detachably connected to the outer wall of the main frame and the outer wall of the water collection pipe by a second screw.
[0011] Furthermore, the inclined brace assembly includes a connecting plate, within which multiple sets of adjusting rods evenly distributed in a circle are rotatably connected, and the end of the adjusting rod away from the connecting plate is detachably connected to the inclined plate.
[0012] Furthermore, the adjusting rod includes a fixed rod, wherein one end of the fixed rod is rotatably connected to the connecting plate, and the other end of the fixed rod is telescopically connected to a movable rod. A limit block is fixedly provided at the end of the movable rod away from the fixed rod, and a through groove is provided on the inclined plate, with the limit block slidably connected to the through groove.
[0013] Furthermore, an adjusting screw is rotatably connected to the end of the fixed rod away from the connecting plate, and the end of the adjusting screw away from the fixed rod is threadedly connected to the movable rod, and a knob is fixedly provided on the adjusting screw.
[0014] Furthermore, a fixing screw is fixedly provided on the limiting block, and at least one nut is threadedly connected to one end of the fixing screw that extends out of the through groove, and the nut abuts against the inner wall of the inclined plate.
[0015] Compared with the prior art, the present invention provides an MBR membrane framework assembly with the following advantages:
[0016] 1. This MBR membrane frame assembly, by setting a reinforcing plate at the connection between the main frame and the water collection pipe, and the reinforcing plate is composed of two L-shaped side plates and an inner plate, can reinforce the water collection pipe from multiple directions, reduce the risk of deformation of the main frame, and help improve the performance.
[0017] 2. This MBR membrane frame assembly has a movable rod that is telescopically connected to the fixed rod. The end of the movable rod away from the fixed rod is fixedly connected to the inclined plate. This not only makes it convenient to adjust the support length of the adjustment rod, but also supports and holds it on the diagonal of the main frame. This can enhance the strength and stability of the frame in multiple directions, making it more resistant to complex and changing external forces.
[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can reinforce the water collection pipe from multiple directions by setting a reinforcing plate at the connection between the main frame and the water collection pipe, reducing the risk of deformation of the main frame.

[0026] Example:
[0027] Reference Figures 1-4An MBR membrane frame assembly includes a main frame, comprising two symmetrically arranged main frames 1 and four parallel water collection pipes 2. Each main frame 1 has two vertical rods 101 and two horizontal rods 102, forming a rectangular frame structure. Reinforcing rods 103 are fixedly connected at the connection points between the horizontal rods 102 and the vertical rods 101 to increase the strength of the main frame 1. The horizontal rods 102, vertical rods 101, and reinforcing rods 103 are preferably connected by welding. Support legs are fixedly connected to the bottom of the vertical rods 101. The length of 2 is less than the length of the water collection pipe 2. The two sets of main frames 1 are located at both ends of the water collection pipe 2, and the four sets of water collection pipes 2 are located at the four corners of the main frame 1. It also includes: a reinforcing plate 3 set at the connection between the main frame 1 and the water collection pipe 2, used to fix the water collection pipe 2 and the main frame 1; and a diagonal bracing assembly, which is detachably connected to the reinforcing plate 3 on the same side. That is, diagonal bracing is set at the side wall of the two sets of main frames 1 near the water collection pipe 2. During use, it can improve the stability and load-bearing capacity of the main frame and reduce the problem of deformation.
[0028] Reference Figure 3 Here, we design the reinforcing plate 3 as an L-shaped inner plate 302. The right-angled surface of the outer side of the inner plate 302 abuts against the inner walls of the main frame 1 and the water collection pipe 2, respectively. An inclined plate 303 is fixedly connected to the right-angled surface of the inner side of the inner plate 302, which can improve the strength of the inner plate 302. The inner plate 302 is detachably connected to the inner wall of the main frame 1 and the inner wall of the water collection pipe 2 by the first screw. The inclined bracing assembly is detachably connected to the inclined plate 303. In use, by using the L-shaped inner plate 302, not only can the water collection pipe 2 be fixed to the main frame 1, but the vertical tilt of the water collection pipe 2 can also be reduced. The inclined plate 303 fixedly connected to the inner wall of the inner plate 302 can increase the strength of the inner plate 302 and improve the performance.
[0029] Reference Figure 3 A side plate 301 is fixedly installed on the outer wall of the inner plate 302. The side plate 301 has an L-shaped structure and is detachably connected to the outer wall of the main frame 1 and the outer wall of the water collection pipe 2 by a second screw. In use, by fixing the side plate 301 to the outer wall of the inner plate 302, the stability of the left and right sides of the water collection pipe 2 can be increased, the deformation can be reduced, and the firmness of the connection between the water collection pipe 2 and the main frame 1 can be improved.
[0030] In use, by setting a reinforcing plate 3 at the connection between the main frame 1 and the water collection pipe 2, the reinforcing plate 3 is composed of two L-shaped side plates 301 and inner plate 302, which can reinforce the water collection pipe 2 from multiple directions, reduce the risk of deformation of the main frame, and help improve the use effect.
[0031] Reference Figure 1 and Figure 4Here, we design the diagonal bracing assembly as a connecting plate 5, which consists of two discs fixedly connected by a fixed shaft. Multiple sets of evenly distributed adjusting rods are rotatably connected within the connecting plate 5. There are two to eight sets of adjusting rods; here, we prefer four sets. The ends of the four adjusting rods furthest from the connecting plate 5 are detached and connected to the corresponding inclined plates 303. At this point, the adjusting rods are diagonally distributed on the main frame. During use, this improves the rigidity and load-bearing capacity of the main frame, reduces deformation, and enhances the performance.
[0032] Reference Figure 1 and Figure 4 Here, we design the adjusting rod as a fixed rod 4, with one end of the fixed rod 4 rotatably connected to the connecting plate 5, facilitating the adjustment of the direction of the fixed rod 4. This is suitable for reinforcing different main frames. A movable rod 401 is telescopically connected to the other end of the fixed rod 4. A limit block 402 is fixedly installed at the end of the movable rod 401 away from the fixed rod 4, and a through groove 304 is provided on the inclined plate 303. The limit block 402 is slidably connected to the through groove 304. To improve the fixing effect, a fixing screw 403 is fixedly installed on the limit block 402. The cross-section of the limit block 402 is rectangular, pentagonal, or hexagonal, preferably rectangular, and more preferably square. The through groove 304 matches the limit block 402, thus restricting the movable rod 401. The rotation of the screw rod 403 is achieved by threading at least one nut, preferably one, at one end extending out of the through groove 304. Using two nuts helps to improve the anti-loosening effect. The nut abuts against the inner wall of the inclined plate 303, and the end of the movable rod 401 away from the fixed rod 4 abuts against the outer wall of the inclined plate 303, so that the adjusting rod has the effect of both a pull rod and a support rod. In use, by telescopically connecting the movable rod 401 to the fixed rod 4, the end of the movable rod 401 away from the fixed rod 4 is fixedly connected to the inclined plate 303. This not only facilitates the adjustment of the support length of the adjusting rod, but also provides support and tension on the diagonal of the main frame. This can enhance the strength and stability of the frame in multiple directions, making it more resistant to complex and variable external forces.
[0033] Reference Figure 4One end of the movable rod 401 can be slidably connected to the fixed rod 4. After the length adjustment is completed, the movable rod 401 is fixed to the fixed rod 4 with bolts. Here, the adjustment method we use is as follows: an adjusting screw 6 is rotatably connected to the end of the fixed rod 4 away from the connecting plate 5. The end of the adjusting screw 6 away from the fixed rod 4 is threadedly connected to the movable rod 401, and a knob 601 is fixedly installed on the adjusting screw 6. In use, by rotating the knob 601, the adjusting screw 6 is rotated, causing the limit block on the movable rod 401 to rotate. 402 extends into the through groove 304 and abuts against the outer wall of the inclined plate 303. Then, the nut is tightened on the fixing screw 403 to fix the movable rod 401 on the inclined plate 303. Then, the remaining movable rods 401 are connected to the inclined plate 303 in the same way. After the connection is completed, the distance between the movable rods 401 and the fixed rods 4 is adjusted as a whole so that the distance between the four sets of movable rods 401 and the fixed rods 4 on the same connecting plate 5 is equal. At this time, a diagonal shape is formed on the main frame, which helps to improve the reinforcement effect.
[0034] 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.
