Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to an MBR membrane frame device. Background Technology

[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 solids in water. At the same time, it combines bioreactors to degrade organic matter. Its core advantages are high water purification capacity, small footprint, and strong effluent water quality stability.

[0003] When using membrane separation technology, the membrane needs to be installed on a membrane frame for operation. Some existing membrane frames directly weld the components together, while others are not very convenient when replacing individual structures. Furthermore, installing the membrane on the frame sometimes requires tools, making the installation process cumbersome. Additionally, when using a membrane frame, fluid enters and exits through pipes. Over time, impurities from the wastewater accumulate inside the pipes, forming scale that obstructs fluid flow. Moreover, the membrane frame needs to be placed in a wastewater tank, but different tanks have varying depths, making it difficult to adjust the membrane frame height and ensuring the membrane is submerged at different depths, thus reducing the membrane frame's practicality. Summary of the Invention

[0004] This invention provides an MBR membrane frame device. The membrane frame of this invention is not connected by electric welding, which facilitates structural replacement. The installation method of the separation membrane is simple and easy to disassemble. When using the membrane frame, the inner wall of the pipe is cleaned to prevent impurities from accumulating on the inner wall of the pipe and forming dirt, which would affect the flow of sewage. When using the membrane frame, the membrane frame can be adjusted up and down, so that the separation membrane can be in sewage at different depths, improving the practicality of the mold frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an MBR membrane frame device, the device comprising:

[0006] Two main frames;

[0007] Multiple first connecting plates are movably embedded in the inner walls of the two main frames, and multiple second connecting plates are movably embedded in the inner walls of the multiple first connecting plates. The multiple first connecting plates can slide on the inner walls of the two main frames. When installing the membrane frame, firstly, the first connecting plates are inserted into the inner walls of the two main frames, and then multiple second connecting plates are inserted into the interior of the two main frames and multiple first connecting plates to build the main body of the membrane frame, which is connected together without welding.

[0008] Multiple slots are respectively opened on one side of multiple second connecting plates, and a fixing plate is movably embedded in the inner wall of each of the multiple slots. The multiple fixing plates can slide on the inner wall of the multiple slots and can be inserted into the interior of the multiple slots.

[0009] Multiple mounting plates are fixedly disposed on one side of the multiple fixed plates, and the multiple mounting plates are arranged in pairs. Multiple separation membranes are provided on the inner wall of each pair of mounting plates. When installing multiple separation membranes, the multiple mounting plates are sleeved on the outer surface of the multiple separation membranes.

[0010] Multiple rotating rods are threaded onto one side of multiple fixed plates. By rotating the multiple rotating rods, the multiple rotating rods are fixed onto the multiple fixed plates, and the mounting plate is further fixed onto the multiple second connecting plates, thereby fixing the multiple separation membranes onto the membrane frame.

[0011] As a further improvement of the present invention: a plurality of second connecting plates are provided with through holes on one side, a plurality of rotating rods are movably embedded in the inner wall of the plurality of through holes, a plurality of second connecting plates are movably embedded in one side of two main frames, a plurality of positioning plates are fixedly provided on one side of one of the main frames, a plurality of second connecting plates are respectively provided on the inner wall of the plurality of positioning plates, and a plurality of second connecting plates are respectively closely attached to a plurality of positioning plates.

[0012] As a further improvement of the present invention: an arc-shaped plate is threaded on one side of each of the two main frames, a sewage pipe is installed on the inner wall of each of the two arc-shaped plates, and a connecting pipe is installed on one side of each of the two sewage pipes. By placing the two arc-shaped plates on one side of the two main frames, the two sewage pipes are installed on the main frames by rotating the screws on the two arc-shaped plates.

[0013] As a further improvement of the present invention: filter plates are installed on the inner walls of both sewage pipes, and transmission rods are provided on both filter plates via bearings. Turbine blades are installed on one side of both transmission rods. The two filter plates can rotate via bearings. When water flows over the two turbine blades, it drives the two turbine blades to rotate, which in turn causes the two transmission rods to rotate.

[0014] As a further improvement of the present invention: a first telescopic rod is fixedly provided on the outer surface of each of the two transmission rods, a second telescopic rod is movably embedded in the inner wall of each of the two first telescopic rods, and a scraper is fixedly provided on one side of each of the two second telescopic rods.

[0015] As a further improvement of the present invention: a spring is fixedly provided on one side of the inner wall of each of the two first telescopic rods, and one side of each spring is fixedly provided on one side of each of the two second telescopic rods. The two springs have elastic force, and the elastic force of the two springs pushes the two second telescopic rods so that one side of each scraper is tightly attached to the inner wall of the sewage pipe.

[0016] As a further improvement of the present invention: L-shaped rods are movably embedded on opposite sides of the two main frames, and sleeve rods are movably sleeved on the outer surfaces of the two L-shaped rods. A square plate is fixedly provided at one end of the two sleeve rods, and a protruding plate is fixedly provided on one side of the square plate. 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.

[0017] As a further improvement of the present invention: two first horizontal shafts are fixedly provided on the inner wall of the convex plate, and pressure rods are movably sleeved on the outer surfaces of the two first horizontal shafts. Second horizontal shafts are movably embedded on the outer surfaces of the two pressure rods. The two pressure rods can rotate about the two second horizontal shafts or the two first horizontal shafts respectively. When the two threaded cylinders move in opposite directions, the two pressure rods will push the convex plate downward, and the square plate will drive the two L-shaped rods to move downward. When the two threaded cylinders move in opposite directions, the two L-shaped rods will be pulled upward, which can further pull the membrane frame.

[0018] As a further improvement of the present invention: threaded cylinders are fixedly provided on both sides of the two second horizontal shafts, and bidirectional threaded rods are threadedly embedded in the inner walls of the two threaded cylinders. Frames are provided at both ends of the bidirectional threaded rods through bearings. Two sliding plates are fixedly provided on the outer surfaces of the two threaded cylinders. Horizontal grooves are opened on both sides of the inner walls of the frames. Multiple sliding plates are slidably disposed on the inner walls of the two horizontal grooves. There are two threaded grooves with different helical directions on the outer surface of the bidirectional threaded rod. The two threaded cylinders are respectively connected to the two threaded grooves with different helical directions, and multiple sliding plates can slide on the inner walls of the two horizontal grooves. Thus, when the bidirectional threaded rod rotates in different directions, the two threaded cylinders move in relative or opposite directions on the outer surface of the bidirectional threaded rod. By rotating the turntable, the bidirectional threaded rod is driven to rotate in different directions, causing the two threaded cylinders to move relative or opposite directions.

[0019] As a further improvement of the present invention: a hook is fixedly provided on one side of the frame, and a turntable is fixedly provided on one side of the bidirectional threaded rod. The turntable facilitates the rotation of the bidirectional threaded rod. By rotating the turntable, the bidirectional threaded rod can be rotated in different directions, and the hook can be lifted to place the membrane frame inside the sewage to be treated.

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

[0021] 1. In this invention, when using the membrane frame device, multiple first connecting plates are inserted into the interior of two first connecting plates. At this time, multiple second connecting plates are inserted from one of the first connecting plates, so that one side of each of the multiple second connecting plates is tightly attached to one side of each of the multiple positioning plates, thus assembling the main body of the membrane frame. Multiple separating membranes are then placed on one side of two of the second connecting plates, and multiple mounting plates are placed on the outer surface of each of the multiple separating membranes. Further, multiple fixing plates are inserted into the interior of multiple slots, and multiple rotating rods are inserted into the interior of multiple through holes. Further, the multiple rotating rods are rotated to fix them onto the multiple fixing plates, and the mounting plates are further fixed onto the multiple second connecting plates, thus fixing the multiple separating membranes onto the membrane frame. Therefore, the membrane frame does not need to be connected by welding, which facilitates structural replacement, and the installation method of the multiple separating membranes is simple and easy to disassemble.

[0022] 2. In this invention, when using a membrane frame to filter wastewater, two arc-shaped plates are placed on one side of two main frames. Two wastewater pipes are installed on the main frames by rotating the screws on the arc-shaped plates. Water flows through the two wastewater pipes to multiple separation membranes for wastewater filtration. When the water flows over two turbine blades, it drives the two turbine blades to rotate, further causing the two transmission rods to rotate. Two second telescopic rods can slide on the inner walls of the two first telescopic rods. Two springs have elastic force, and the elastic force of the two springs pushes the two second telescopic rods, causing one side of the two scrapers to press tightly against the membrane. Inside the sewage pipes, sewage first flows through filter plates into the two sewage pipes. The sewage is filtered through the perforations on the filter plates by a small particle filter. When the two turbine blades rotate, they drive the two transmission rods to rotate, further causing the two scrapers to rotate. The two scrapers press tightly against the inner walls of the two sewage pipes, cleaning the inner walls. This prevents impurities from accumulating and forming scale, which could affect the flow of sewage. It also protects the head from gaps at the connection between the second end cap and the shell, preventing fluid overflow.

[0023] 3. In this invention, when using the membrane frame, it can be placed inside the wastewater to be treated by suspending it with hooks. Two L-shaped rods can slide inside two sleeve rods respectively. By sliding the two L-shaped rods, they are inserted into both sides of the main frame, connecting them to the membrane frame. The outer surface of the bidirectional threaded rod has two threaded grooves with different directions of rotation. Two threaded cylinders are connected to the two threaded grooves with different directions of rotation, and multiple sliding plates can slide on the inner walls of the two transverse grooves. Therefore, when the bidirectional threaded rod rotates in different directions, the two threaded cylinders move in opposite or opposite directions on the outer surface of the bidirectional threaded rod. The movement is achieved by rotating the turntable, which drives the bidirectional threaded rod to rotate in different directions, causing the two threaded cylinders to move relative to or in opposite directions. 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 opposite directions, the two pressure rods push the convex plate downwards, which in turn drives the two L-shaped rods downwards through the square plate. When the two threaded cylinders move in opposite directions, they pull the two L-shaped rods upwards, which can further pull the membrane frame. Thus, when using the membrane frame, it can be adjusted up and down, allowing multiple separation membranes to be placed in wastewater at different depths, improving the practicality of the mold frame.

Multiple positioning plates 208 are fixedly installed on one side of one of the main frames 1. The sides of multiple second connecting plates 201 are respectively located on the inner wall of multiple positioning plates 208.

[0042] In use, multiple first connecting plates 2 are inserted into the interior of two first connecting plates 2 respectively. At this time, multiple second connecting plates 201 are inserted from one of the first connecting plates 2 respectively, so that one side of the multiple second connecting plates 201 is tightly attached to one side of the multiple positioning plates 208, thus assembling the main body of the membrane frame. At this time, multiple separation membranes 205 are placed on one side of two of the second connecting plates 201 respectively, and multiple mounting plates 204 are placed on the outer surface of the multiple separation membranes 205 respectively. Further, multiple fixing plates 203 are inserted into the interior of multiple slots 202, and multiple rotating rods 206 are inserted into the interior of multiple through holes 207 respectively. Further, the multiple rotating rods 206 are rotated to fix the multiple rotating rods 206 on the multiple fixing plates 203. Further, the mounting plates 204 are fixed on the multiple second connecting plates 201, thus fixing the multiple separation membranes 205 on the membrane frame.

[0043] Please see Figures 1 to 9 In one embodiment, an arc-shaped plate 3 is threaded on one side of each of the two main frames 1, and a sewage pipe 301 is installed on the inner wall of each of the two arc-shaped plates 3. A connecting pipe 302 is installed on one side of each of the two sewage pipes 301. By placing the two arc-shaped plates 3 on one side of the two main frames 1, the two sewage pipes 301 are installed on the main frames 1 by rotating the screws on the two arc-shaped plates 3.

[0044] Please see Figures 1 to 9 In one embodiment, filter plates 303 are installed on the inner walls of the two sewage pipes 301. Each filter plate 303 is equipped with a transmission rod 309 via a bearing. Turbine blades 304 are installed on one side of each transmission rod 309. The two filter plates 303 can rotate via the bearings. When water flows over the two turbine blades 304, it drives the two turbine blades 304 to rotate, which in turn causes the two transmission rods 309 to rotate.

[0045] Please see Figures 1 to 9 In one embodiment, a first telescopic rod 305 is fixedly provided on the outer surface of each of the two transmission rods 309, a second telescopic rod 306 is movably embedded in the inner wall of each of the two first telescopic rods 305, and a scraper 307 is fixedly provided on one side of each of the two second telescopic rods 306.

[0046] Please see Figures 1 to 9In one embodiment, a spring 308 is fixedly provided on one side of the inner wall of each of the two first telescopic rods 305. One side of the two springs 308 is fixedly provided on one side of the two second telescopic rods 306. 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 tightly attached to the inner wall of the sewage pipe 301.

[0047] Please see Figures 1 to 9 In one embodiment, L-shaped rods 4 are movably embedded on opposite sides of the two main frames 1. Sleeve rods 401 are movably sleeved on the outer surfaces of the two L-shaped rods 4. A square plate 402 is fixedly provided at one opposite end of the two sleeve rods 401. A protruding plate 403 is fixedly provided on one side of the square plate 402. 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.

[0048] Please see Figures 1 to 9 In one embodiment, two first horizontal shafts 404 are fixedly provided on the inner wall of the convex plate 403. Pressure rods 405 are movably sleeved on the outer surface of each of the two first horizontal shafts 404. Second horizontal shafts 406 are movably embedded on the outer surface of each of the two pressure rods 405. The two pressure rods 405 can rotate about the two second horizontal shafts 406 or the two first horizontal shafts 404 respectively. When the two threaded cylinders 407 move in opposite directions, the two pressure rods 405 push the convex plate 403 downward. The square plate 402 drives the two L-shaped rods 4 to move downward. When the two threaded cylinders 407 move in opposite directions, the two L-shaped rods 4 are pulled upward, which can further pull the membrane frame.

[0049] Please see Figures 1 to 9 In one embodiment, threaded cylinders 407 are fixedly provided on both sides of the two second horizontal shafts 406. A bidirectional threaded rod 408 is threadedly embedded in the inner wall of the two threaded cylinders 407. A frame 409 is provided at both ends of the bidirectional threaded rod 408 through bearings. Two sliding plates 410 are fixedly provided on the outer surface of the two threaded cylinders 407. A transverse groove 411 is opened on both sides of the inner wall of the frame 409. Multiple sliding plates 410 are slidably disposed on the inner wall of the two transverse grooves 411. There are two threaded grooves with different helical directions on the outer surface of the bidirectional threaded rod 408. The two threaded cylinders 407 are respectively connected to the two threaded grooves with different helical directions, and multiple sliding plates 410 can slide on the inner wall of the two transverse grooves 411. Thus, when the bidirectional threaded rod 408 rotates in different directions, the two threaded cylinders 407 move in relative or opposite directions on the outer surface of the bidirectional threaded rod 408.

[0050] Please see Figures 1 to 9In one embodiment, a hook 413 is fixedly provided on one side of the frame 409, and a turntable 412 is fixedly provided on one side of the bidirectional threaded rod 408. The turntable 412 facilitates the rotation of the bidirectional threaded rod 408. By rotating the turntable 412, the bidirectional threaded rod 408 can be rotated in different directions. By lifting the hook 413, the membrane frame can be placed inside the sewage to be treated.

[0051] Working principle: When using the membrane frame device, multiple first connecting plates 2 are inserted into the interior of two first connecting plates 2 respectively. At this time, multiple second connecting plates 201 are inserted from one of the first connecting plates 2 respectively, so that one side of the multiple second connecting plates 201 is tightly attached to one side of multiple positioning plates 208, thus assembling the main body of the membrane frame. At this time, multiple separation membranes 205 are placed on one side of two of the second connecting plates 201 respectively, and multiple mounting plates 204 are placed on the outer surface of multiple separation membranes 205 respectively. Further, multiple fixing plates 203 are inserted into the interior of multiple slots 202, and multiple rotating rods 206 are inserted into the interior of multiple through holes 207 respectively. Further rotating the multiple rotating rods 206 fixes the multiple rotating rods 206 on the multiple fixing plates 203. Further fixing the mounting plates 204 on the multiple second connecting plates 201, thus fixing the multiple separation membranes 205 on the membrane frame. Thus, the membrane frame does not need to be connected by electric welding, which is convenient for structural replacement. Moreover, the installation method of multiple separation membranes 205 is simple and easy to disassemble.

[0052] When using a membrane frame to filter wastewater, two arc-shaped plates 3 are placed on one side of two main frames 1. Two wastewater pipes 301 are installed on the main frames 1 by rotating the screws on the arc-shaped plates 3. Water flows through the two wastewater pipes 301 to multiple separation membranes 205 for wastewater filtration. When the water flows over the two turbine blades 304, it drives the two turbine blades 304 to rotate, further causing the two drive rods 309 to rotate. 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 in close contact with the inner wall of the sewage pipe 301. The sewage first flows through the filter plate 303 into the inside of the two sewage pipes 301. The sewage is filtered by the small particle device through the leakage holes on the two filter plates 303. When the two turbine blades 304 rotate, they will drive the two transmission rods 309 to rotate, which will further cause the two scrapers 307 to rotate. The two scrapers 307 are in close contact with the inner wall of the two sewage pipes 301 to clean the inner wall of the sewage pipes 301. Thus, when using the membrane frame, the inner wall of the pipe is cleaned to prevent impurities from accumulating on the inner wall of the pipe and forming dirt, which would affect the flow of sewage.

[0053] When using the membrane frame, by suspending it with hook 413, the membrane frame can be placed inside the wastewater to be treated. Two L-shaped rods 4 can slide inside the two sleeve rods 401 respectively. By sliding the two L-shaped rods 4, they are inserted into both sides of the main frame 1, connecting them to the membrane frame. The outer surface of the bidirectional threaded rod 408 has two threaded grooves with different directions of rotation. Two threaded cylinders 407 are connected to the two threaded grooves with different directions of rotation, and multiple sliding plates 410 can slide on the inner walls of the two transverse grooves 411. Therefore, when the bidirectional threaded rod 408 rotates in different directions, the two threaded cylinders 407 move in opposite or relative directions on the outer surface of the bidirectional threaded rod 408. The rotating turntable 412 drives the bidirectional threaded rod 408 to rotate in different directions, causing the two threaded cylinders 407 to move relative to or in opposite directions. The two pressure rods 405 can rotate around the two second horizontal axes 406 or the two first horizontal axes 404 respectively. When the two threaded cylinders 407 move in opposite directions, the two pressure rods 405 push the convex plate 403 downward, which in turn drives the two L-shaped rods 4 downward through the square plate 402. When the two threaded cylinders 407 move in opposite directions, they pull the two L-shaped rods 4 upward, which can further pull the membrane frame. Thus, when using the membrane frame, it can be adjusted up and down, so that multiple separation membranes 205 can be placed in sewage at different depths, improving the practicality of the mold frame.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
