[0002] The MBR membrane frame is a frame-type carrier used to install MBR membranes, aeration pipes, water collection pipes, air inlet pipes and other devices. It is installed in the sewage pool for use. It uses the filtering characteristics of the MBR membrane to effectively remove a large amount of organic matter and other impurities contained in the sewage, thereby purifying the environment.

[0003] Traditional membrane module frames are generally made of stainless steel and welded together, which can lead to the following problems in actual operation:

[0004] 1. Since the MBR membrane frame is usually placed in the sewage pool, a large number of bubbles will be generated in the sewage pool. The bubbles will corrode the welding parts of the MBR membrane frame for a long time, causing corrosion and fracture of the welding parts of the MBR membrane frame;

[0005] 2. Since the MBR membrane frame is welded with stainless steel, the length of the MBR membrane frame is fixed. Only multiple sets of MBR membrane frames can be placed in the sewage pool, and it is impossible to freely assemble the appropriate size according to the size of the sewage pool. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the present invention is: to provide an MBR membrane frame structure to solve the current MBR membrane frame welding joints being eroded by bubbles for a long time, resulting in the MBR membrane frame welding joints being broken, the MBR membrane frame cannot be freely assembled in size, and a large number of MBR membranes, aeration pipes, water collection pipes and water inlet pipes are installed on the MBR membrane frame. These items are fixed to the MBR membrane frame with fixing equipment, and the fixing method usually damages the MBR membrane frame, resulting in the technical problem that the MBR membrane frame is easily deformed after long-term use.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] An MBR membrane frame structure includes a membrane wire frame, wherein a detachable frame assembly is fixedly mounted on the outer surface of the membrane wire frame;

[0010] The detachable frame assembly includes a transverse frame assembly, and the transverse frame assembly includes a transverse rod. The outer surface of the transverse rod is provided with a fixing groove, the inner surface of the fixing groove is clamped with a rubber cover, and the back of the rubber cover is fixedly installed with a card cover.

[0011] As an improved technical solution, the detachable frame assembly also includes a connecting assembly, which includes a longitudinal rod, and connecting plates are fixedly installed at both ends of the longitudinal rod, and the outer surfaces of the connecting plates are fixedly connected to the opposite sides of the two transverse rods.

[0012] As an improved technical solution, the connecting assembly further comprises a bolt, one end of which passes through the transverse rod and the connecting plate in sequence and extends into the interior of the transverse rod, and a nut is threadedly mounted on the outer surface of the bolt.

[0013] As an improved technical solution, a detachable fixing component is fixedly installed on the outer surface of the transverse rod, and the detachable fixing component includes a card slot, which is opened at the top and bottom of the transverse rod, and the inner surface of the card slot is provided with a threaded groove.

[0014] As an improved technical solution, the detachable fixing assembly further includes a No. 1 card rack, the outer surface of the No. 1 card rack is clamped and installed with the inner surface of the card slot, and the inner surface of the No. 1 card rack is fixedly connected to the outer surface of the membrane wire rack.

[0016] As an improved technical solution, the detachable fixing assembly further includes a second bracket, the inner surface of which is fixedly mounted with a water outlet pipe, the outer surface of which is connected to the top of the membrane wire rack via a connecting pipe.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The utility model adds a design for the free combination of MBR membrane frames, and uses the horizontal rods and fixing grooves in conjunction with the longitudinal rods and connecting plates, and the bolts and nuts in conjunction with the connecting plates, thereby achieving the goal of changing the original stainless steel welding method to assembly by bolts and nuts, so that the MBR membrane frames can be freely assembled according to the size of the sewage pool, and there is no need to place multiple groups of MBR membrane frames in the sewage pool. At the same time, the rubber cover and the card cover are used in conjunction with the fixing groove to seal the connection parts of the MBR membrane frames, so that bubbles and sewage cannot corrode the bolts and nuts, effectively preventing bubbles from eroding the welding parts of the MBR membrane frames for a long time, causing corrosion and fracture of the welding parts of the MBR membrane frames.

[0019] 2. The utility model adds a design for fixing the external items of the MBR membrane frame detachable, through the coordinated use of the transverse rod with the card slot and the threaded groove, the coordinated use of the threaded groove and the card slot with the No. 1 card frame and the fixing bolt, and the coordinated use of the card slot and the No. 2 card frame with the outlet pipe and the connecting pipe, so that the pipes compatible with the MBR membrane frame can be fixed, and at the same time, there is no need to drill holes in the stainless steel to destroy the MBR membrane frame structure, which would cause the MBR membrane frame to be easily deformed after long-term use.
