Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to an MBR membrane frame device. Background Art

[0002] MBR is a wastewater treatment method that combines biological treatment and membrane separation technology. It uses membrane separation technology to replace traditional sedimentation tanks to achieve effective separation of solids and suspended matter in water, while combining bioreactors to degrade organic matter. Its core advantages are efficient water purification capabilities, smaller footprint and stronger effluent water quality stability.

[0003] When using membrane separation technology, the separation membrane needs to be installed on the membrane frame before it can be used. Some existing membrane frames directly weld the components together by welding, and some need to replace a single structure which is not very convenient. At the same time, when the separation membrane is installed on the membrane frame, some tools are needed to complete the installation of the separation membrane. The installation method is relatively troublesome. Moreover, when using the membrane frame, the fluid enters and exits through pipes. After long-term use, some impurities in the sewage will stick to the inside of the pipes. The impurities will accumulate on the inner wall of the pipes to form dirt, affecting the passage of the fluid. When using the membrane frame, it needs to be placed in a sewage pool, but the sewage depth inside different sewage pools is different, and the height of the membrane frame is difficult to adjust. The separation membrane is difficult to be in sewage of different depths, reducing the practicality of the membrane frame. Summary of the invention

[0004] The present invention provides an MBR membrane frame device. The membrane frame of the present invention does not need to be connected by electric welding, which is convenient for replacing the structure. The installation method of the separation membrane is simple and convenient for disassembly. When the membrane frame is used, the inner wall of the pipeline is cleaned to prevent impurities from accumulating on the inner wall of the pipeline to form dirt and affect the inflow of sewage. When the membrane frame is used, the membrane frame can be adjusted up and down so that the separation membrane can be placed in sewage at different depths, thereby improving the practicality of the mold frame.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] 1. In the present invention, when using the membrane frame device, multiple first connecting plates are respectively inserted into the interior of two first connecting plates, and multiple second connecting plates are respectively inserted from one of the first connecting plates, so that one side of the multiple second connecting plates is respectively close to one side of the multiple positioning plates, to form the main body of the membrane frame, and multiple separation membranes are respectively placed on one side of two of the second connecting plates, and multiple mounting plates are respectively placed on the outer surface of the multiple separation membranes, and further multiple fixing plates are inserted into the interior of multiple notches, and then multiple rotating rods are respectively inserted into the interior of multiple through holes, and further multiple rotating rods are rotated so that the multiple rotating rods are fixed on the multiple fixing plates, and further the mounting plates are fixed on the multiple second connecting plates, and the multiple separation membranes are fixed on the membrane frame, so that the membrane frame does not need to be connected by electric welding, which is convenient for replacing the structure, and the installation method of the multiple separation membranes is simple and easy to disassemble.

[0022] 2. In the present invention, when using the membrane frame to filter sewage, two arc-shaped plates are placed on one side of two main frames, and two sewage pipes are installed on the main frames by rotating the screws on the two arc-shaped plates. Water flows through the two sewage pipes to multiple separation membranes for sewage filtration.

Therefore, when the membrane frame is used, the inner wall of the pipe is cleaned to prevent impurities from accumulating on the inner wall of the pipe to form dirt, affecting the inflow of sewage to protect the head, and prevent gaps from appearing at the connection between the second head and the shell, which may cause fluid overflow.

[0023] 3. In the present invention, when the membrane frame is used, the membrane frame can be placed inside the sewage to be treated by lifting the hook, and the two L-shaped rods can slide inside the two sleeve rods respectively. By sliding the two L-shaped rods, the two L-shaped rods are inserted into the two sides of the main frame, and the two L-shaped rods are connected to the membrane frame. There are two thread grooves with different rotation directions on the outer surface of the two-way threaded rod, and the two threaded cylinders are respectively connected to the two thread grooves with different rotation directions, and a plurality of slide plates can slide on the inner walls of the two transverse grooves respectively, so that when the two-way threaded rod rotates in different directions, the two threaded cylinders move in relative or opposite directions on the outer surface of the two-way threaded rod. Move, at this time, the two-way threaded rod is driven to rotate in different directions by rotating the turntable, so that the two threaded cylinders move relative to or oppositely, and the two pressure rods can rotate around the two second horizontal axes or the two first horizontal axes respectively. When the two threaded cylinders move in relative directions, the two pressure rods will push the convex plate downward, and further drive the two L-shaped rods to move downward through the square plate. When the two threaded cylinders move in opposite directions, the two L-shaped rods will be pulled upward, and the membrane frame can be further pulled. Therefore, when the membrane frame is used, the membrane frame can be adjusted up and down, so that multiple separation membranes can be placed in sewage at different depths, thereby improving the practicability of the mold frame.

[0051] Working principle: When using the membrane frame device, the plurality of first connecting plates 2 are respectively inserted into the interior of the two first connecting plates 2, and the plurality of second connecting plates 201 are respectively inserted from one of the first connecting plates 2, so that one side of the plurality of second connecting plates 201 is respectively close to one side of the plurality of positioning plates 208, and the main body of the membrane frame is formed. At this time, the plurality of separation membranes 205 are respectively placed on one side of two of the second connecting plates 201, and the plurality of mounting plates 204 are respectively placed on the outer surface of the plurality of separation membranes 205, and the plurality of fixing plates 203 are further inserted into the interior of the plurality of notches 202, and then the plurality of rotating rods 206 are respectively inserted into the interior of the plurality of through holes 207, and the plurality of rotating rods 206 are further rotated so that the plurality of rotating rods 206 are fixed on the plurality of fixing plates 203, and the mounting plates 204 are further fixed on the plurality of second connecting plates 201, and the plurality of separation membranes 205 are fixed on the membrane frame, so that the membrane frame does not need to be connected by electric welding, which is convenient for replacing the structure, and the installation method of the plurality of separation membranes 205 is simple, and convenient for disassembly;

[0052] When using the membrane frame to filter sewage, two arc plates 3 are placed on one side of the two main frames 1, and two sewage pipes 301 are installed on the main frames 1 by rotating the screws on the two arc plates 3. Water flows through the two sewage pipes 301 to the multiple separation membranes 205 for sewage filtration. When the water flows through the two turbine blades 304, the two turbine blades 304 are driven to rotate, and the two transmission rods 309 are further rotated. The two second telescopic rods 306 can slide on the inner walls of the two first telescopic rods 305 respectively. The two springs 308 have elastic force, and the elastic force of the two springs 308 pushes the two second telescopic rods 306, so that one side of the two scrapers 307 is closely attached to the inner wall of the sewage pipe 301, the sewage first flows into the inside of the two sewage pipes 301 through the filter plate 303, and the small particles of sewage are filtered through the leakage holes on the two filter plates 303. When the two turbine blades 304 rotate, the two transmission rods 309 are driven to rotate, and the two scrapers 307 are further rotated. The two scrapers 307 are closely attached to the inner wall of the two sewage pipes 301, and the inner wall of the sewage pipe 301 is cleaned, so that when the membrane frame is used, the inner wall of the pipe is cleaned to prevent impurities from accumulating on the inner wall of the pipe to form dirt and affect the inflow of sewage;

[0053] When using the membrane frame, the membrane frame can be placed inside the sewage to be treated by lifting the hook 413, and the two L-shaped rods 4 can slide inside the two sleeve rods 401 respectively. By sliding the two L-shaped rods 4, the two L-shaped rods 4 are inserted into the two sides of the main frame 1, and the two L-shaped rods 4 are connected to the membrane frame. There are two thread grooves with different rotation directions on the outer surface of the two-way threaded rod 408, and the two threaded cylinders 407 are respectively connected to the two thread grooves with different rotation directions, and multiple slides 410 can slide on the inner walls of the two transverse grooves 411 respectively. When the two-way threaded rod 408 rotates in different directions, the two threaded cylinders 407 move in relative or opposite directions on the outer surface of the two-way threaded rod 408. At this time, By rotating the turntable 412, the bidirectional threaded rod 408 is driven to rotate in different directions, so that the two threaded cylinders 407 move relative to or oppositely, and the two pressure rods 405 can rotate with the two second horizontal axes 406 or the two first horizontal axes 404 as axes. Further, when the two threaded cylinders 407 move in relative directions, the two pressure rods 405 will push the convex plate 403 downward, and further drive the two L-shaped rods 4 to move downward through the square plate 402. When the two threaded cylinders 407 move in opposite directions, the two L-shaped rods 4 will be pulled upward, and the membrane frame can be further pulled. Therefore, when the membrane frame is used, the membrane frame can be adjusted up and down, so that multiple separation membranes 205 can be placed in sewage at different depths, thereby improving the practicality of the mold frame.
