Abstract
Description
Technical Field
[0001] This utility model relates to the field of MBR membrane frame installation technology, and in particular to a quick-installation anti-loosening boom structure for MBR membrane frames. Background Technology
[0002] MBR (Membrane Bioreactor) is a highly efficient combination of membrane separation technology and biological treatment, used to replace the secondary sedimentation tank in the activated sludge process. There are generally two installation methods for MBR membrane modules within the tank: one is a rail-fixed installation, and the other is an in-tank suspension installation. Currently, to improve the treatment capacity of the biological system, the sludge concentration is generally maintained at a high level, reaching 10,000-12,000 mg / L, leading to sludge accumulation at the bottom of the tank. If the rail-fixed installation method is used, the aeration pipes of the membrane module are too close to the bottom, easily causing sludge blockage and uneven aeration, ultimately affecting the operation of the membrane system. Therefore, the in-tank suspension installation method is now more commonly used.
[0003] The original MBR membrane module was installed in a suspended manner, with the connection points fixed by bolts and double nuts. Because the MBR membrane module is constantly aerated and shaken during operation, the bolts and nuts are prone to loosening and falling off, which poses a risk that the membrane frame may fall to the bottom of the tank. On the one hand, there is a safety concern about the membrane frame falling off, and on the other hand, the membrane frame falling off will cause the permeate interface and air inlet interface to disconnect, ultimately causing the entire MBR system to fail to operate normally.
[0004] To address the aforementioned issues, we propose a quick-installation, anti-loosening boom structure for MBR membrane frames. Utility Model Content
[0005] The purpose of this invention is to provide a quick-installation anti-loosening boom structure for MBR membrane frames, which solves the problems of low installation efficiency, easy loosening, and difficult disassembly and maintenance of existing MBR membrane frame boom structures.
[0006] To achieve the above objectives, this utility model employs a quick-installation anti-loosening boom structure for MBR membrane frames, comprising a tank body and a quick-release anti-loosening assembly. The quick-release anti-loosening assembly includes a support plate, a suspension boom, a connecting steel plate, bolts, and double nuts. The support plate is detachably connected to the tank body and is located on the upper side of the tank body. The suspension boom is detachably connected to the support plate and is located below the support plate, with the suspension boom perpendicular to the support plate. The connecting steel plate is detachably connected to the suspension boom and is located below the suspension boom, with the connecting steel plate located inside the tank body. One end of the bolt is located above the connecting steel plate, and the other end is located below the connecting steel plate. The double nuts are located on the lower outer surface of the bolt and are also located below the connecting steel plate.
[0007] The quick-release anti-loosening component also includes a column, which passes through the connecting steel plate and is detachably connected to the suspension arm, and is located below the suspension arm, with the column and the connecting steel plate being perpendicular to each other.
[0008] The quick-release anti-loosening component also includes a crossbar, which is detachably connected to the column and located on one side of the column. The crossbar is positioned below the connecting steel plate and is also perpendicular to the column.
[0009] The quick-release anti-loosening component also includes a base frame, which is detachably connected to the column and located below the column. The base frame is also positioned below the cross frame and is parallel to the cross frame.
[0010] The quick-release anti-loosening assembly further includes a membrane assembly, which is detachably connected to the cross frame and located below the cross frame. The membrane assembly is also positioned above the base frame and is located inside the pool body.

[0019] This utility model provides a quick-installation anti-loosening boom structure for MBR membrane holders, including a tank body 101 and a quick-release anti-loosening component. The quick-release anti-loosening component includes a support plate 102, a suspension boom 103, a connecting steel plate 104, bolts 105, double nuts 106, a column 107, a crossbar 108, a base frame 109, and a membrane module 110. This solution solves the problems of low installation efficiency, easy loosening, and difficult disassembly and maintenance of existing MBR membrane holder boom structures. It is understood that, during use, the bolts 105 are used to fix the connecting steel plate 104 to the connection points of each component, thus securing the membrane module. One end of the bolt 105 passes through the mounting hole above the connecting steel plate 104, and the other end protrudes from below the connecting steel plate 104. At the end of the bolt 105 protruding from below the connecting steel plate 104, the double nuts 106 are installed sequentially. The first nut is installed first, and after tightening to a certain extent, the second nut is installed. A double-nut anti-loosening method is used, with the two nuts locking each other to prevent the bolt 105 from loosening and falling off due to aeration vibration during MBR membrane module operation. This ensures the connection stability of the entire boom structure. After all components are installed, a comprehensive inspection of the MBR membrane frame quick-installation anti-loosening boom structure is conducted. After confirming that all components are securely connected and accurately positioned, fill the tank 101 with water and observe the stability of the membrane frame in the water. Check for any abnormalities such as swaying or tilting. Simultaneously, turn on the aeration system to simulate the operating conditions of the membrane module. Check whether the connection points of the boom structure are loose under aeration vibration and whether the membrane module 110 is operating normally. If any problems are found, stop the machine immediately for adjustment and tightening until the operating requirements are met. During the operation of the MBR membrane frame, regularly inspect and maintain the boom structure, checking whether the connection between the bolts 105 and the double nuts 106 is loose, and whether any components are damaged or deformed. Furthermore, if the bolt 105 is found to be loose, tighten the double nut 106 with a wrench for reinforcement. If a component is damaged, it needs to be replaced according to the actual situation. When it is necessary to repair the membrane frame or replace the membrane assembly 110, disassemble in the reverse order of installation. First, loosen the double nut 106, remove the bolt 105, and then disassemble the membrane assembly 110, the base frame 109, the cross frame 108, the column 107, the connecting steel plate 104, the suspension arm 103, and the support plate 102 in sequence. Clean, inspect, and repair the disassembled components to prepare for the next installation.
[0020] In this specific embodiment, the support plate 102 is detachably connected to the pool body 101 and is located on the upper side inside the pool body 101. The suspension arm 103 is detachably connected to the support plate 102 and is located below the support plate 102, and the suspension arm 103 is perpendicular to the support plate 102. The connecting steel plate 104 is detachably connected to the suspension arm 103 and is located below the suspension arm 103, and the connecting steel plate 104 is located inside the pool body 101. One end of the bolt 105 is located above the connecting steel plate 104, and the other end of the bolt 105 is located below the connecting steel plate 104. The double nut 106 is located on the lower outer surface of the bolt 105, and the double nut 106 is also located below the connecting steel plate 104.
[0021] The column 107 is detachably connected to the suspension arm 103 through the connecting steel plate 104 and is located below the suspension arm 103. The column 107 is perpendicular to the connecting steel plate 104. When installing the column 107 through the connecting steel plate 104 and detachably connected to the suspension arm 103, it is necessary to ensure that the column 107 is perpendicular to the connecting steel plate 104. A right-angle ruler can be used for measurement and calibration. Tighten the connection to prevent the column 107 from shaking.
[0022] Secondly, the crossbeam 108 is detachably connected to the column 107 and is located on one side of the column 107. The crossbeam 108 is located below the connecting steel plate 104 and is also perpendicular to the column 107.
[0023] Meanwhile, the base frame 109 is detachably connected to the column 107 and is located below the column 107. The base frame 109 is also located below the cross frame 108 and is parallel to the cross frame 108.
[0024] In addition, the membrane module 110 is detachably connected to the cross frame 108 and located below the cross frame 108. The membrane module 110 is also located above the base frame 109 and inside the pool body 101. The membrane module 110 is detachably connected to the cross frame 108 so that the membrane module 110 is located below the cross frame 108, above the base frame 109, and inside the pool body 101. According to the installation requirements of the membrane module 110, the membrane module 110 is fixed to the cross frame 108 using appropriate connectors to ensure stable installation and prevent the membrane module 110 from shifting during operation.
[0025] When using this utility model, the bolts 105 are used to fix the connection between the connecting steel plate 104 and each component. One end of the bolt 105 passes through the mounting hole above the connecting steel plate 104, and the other end passes through the bottom of the connecting steel plate 104. At the end of the bolt 105 that passes through the bottom of the connecting steel plate 104, the double nuts 106 are installed sequentially. The first nut is installed first, and after tightening to a certain extent, the second nut is installed. A double-nut anti-loosening method is used, where the two nuts are locked together to prevent the bolts 105 from loosening and falling off due to aeration vibration during the operation of the MBR membrane module, ensuring the connection stability of the entire boom structure. After all components are installed, a comprehensive inspection of the MBR membrane frame quick-installation anti-loosening boom structure is conducted to confirm that each component is firmly connected and accurately installed. Water is injected into the tank 101, and the stability of the membrane frame in the water is observed to check for any abnormalities such as shaking or tilting. Simultaneously, the aeration system is turned on to simulate the operating conditions of the membrane module and to check... Check whether the connection parts of the boom structure are loose under aeration vibration, and whether the membrane module 110 is operating normally. If any problems are found, stop the machine in time for adjustment and tightening until the operating requirements are met. During the operation of the MBR membrane frame, regularly inspect and maintain the boom structure, check whether the connection between the bolt 105 and the double nut 106 is loose, and whether any parts are damaged or deformed. If the bolt 105 is found to be loose, tighten the double nut 106 with a wrench for reinforcement. If any parts are damaged, they need to be replaced according to the actual situation. When it is necessary to repair the membrane frame or replace the membrane module 110, disassemble in the reverse order of installation. First, loosen the double nut 106, remove the bolt 105, and then disassemble the membrane module 110, the base frame 109, the cross frame 108, the column 107, the connecting steel plate 104, the suspension boom 103, and the support plate 102 in sequence. Clean, inspect, and repair the disassembled parts to prepare for the next installation.
