Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to an MBR membrane chemical fiber wastewater treatment device. Background Technology

[0002] The MBR membrane chemical fiber wastewater treatment device is a wastewater treatment equipment that combines membrane bioreactor technology with the wastewater treatment needs of the chemical fiber industry. It utilizes the combination of biodegradation and membrane filtration technology to effectively treat the wastewater generated during the chemical fiber production process.

[0003] According to the published patent CN215049030U, an MBR membrane wastewater treatment device includes a reaction tank. An MBR membrane system is installed inside the reaction tank, and membrane fibers are installed inside the MBR membrane system. Limiting blocks are provided outside the membrane fibers, and limiting holes are formed inside the limiting blocks. This invention also includes limiting blocks with limiting holes inside. The number of limiting holes is the same as the number of membrane fibers in a single MBR membrane system. During the assembly of the MBR membrane system, individual membrane fibers are passed through the limiting holes to limit their movement. When aeration begins at the bottom, the gas washes over the membrane fibers, causing them to sway. However, under the action of the limiting blocks, the swaying amplitude of the membrane fibers is reduced. With less swaying amplitude, the membrane fibers do not have enough distance to entangle. Therefore, by installing individual membrane fibers in the limiting holes, the entanglement of membrane fibers during aeration is avoided. However, the following shortcomings still exist:

[0004] When treating wastewater, uneven wastewater flow or changes in flow velocity may cause fluctuations on the membrane surface, leading to membrane shaking. The shaking of the membrane module may affect the wastewater treatment effect. Therefore, we propose an MBR membrane wastewater treatment device. Summary of the Invention

[0005] The purpose of this utility model is to provide an MBR membrane chemical fiber wastewater treatment device. By using a limiting plate that can be inserted into the fixed frame to position the connecting frame, and then tightening the bolts in the limiting plate and the fixed frame to fix the connecting frame, the problem of fixing the MBR membrane module inside the device is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an MBR membrane chemical fiber wastewater treatment device, including a shell, a top cover slidably connected to the inner wall of the shell, a disassembly mechanism provided on the top cover, and a fixing mechanism provided on the top cover;

[0008] The disassembly mechanism includes a connecting block, a fixing block slidably connected to the outer surface of the connecting block, a bolt threadedly connected to the inner wall of the fixing block, a fixing rod fixedly connected to the inner wall of the top cover, a C-shaped buckle slidably connected to the outer surface of the fixing rod, a connecting frame fixedly connected to the bottom of the C-shaped buckle, a limit plate fixedly connected to the bottom of the connecting frame, a fixing frame slidably connected to the outer surface of the limit plate, a bolt threadedly connected to the inner wall of the fixing frame, and an MBR membrane module slidably connected to the inner wall of the connecting frame.

[0009] Furthermore, there are two connecting blocks, the outer surface of which is fixedly connected to the outer surface of the top cover. There are several fixing blocks, the outer surface of which is fixedly connected to the outer surface of the housing. The outer surface of the bolt is rotatably connected to the inner wall of the connecting block.

[0010] Furthermore, there are two fixing rods, and the outer surface of the fixing frame is slidably connected to the inner wall of the housing. There are two bolts, and the outer surface of the bolts is rotatably connected to the inner wall of the limiting plate. The top of the MBR membrane module is in contact with the bottom of the top cover.

[0011] Furthermore, the fixing mechanism includes a water inlet fixedly connected to the inner wall of the top cover, a dustproof and breathable cover being snapped onto the outer surface of the water inlet, and a limiting block being fixedly connected to the inner wall of the housing, with a total of several limiting blocks provided.

[0012] Furthermore, the inner wall of the limiting block is threaded with three bolts, and there are two bolts in total. The outer surface of the bolts is rotatably connected to the inner wall of the fixing frame. The bottom of the fixing frame is fixedly connected to an insert plate, and the outer surface of the insert plate is slidably connected to a positioning frame.

[0013] Furthermore, the bottom of the positioning frame is fixedly connected to the inner wall of the housing, and the insert plate has a slot inside. There are two slots in total, and insert blocks are inserted into the inner wall of the slot.

[0014] Furthermore, a sliding rod is fixedly connected to the side of the insert block away from the insert plate, and a connecting shell is slidably connected to the outer surface of the sliding rod. The bottom of the connecting shell is fixedly connected to the inner wall of the shell.

[0015] Furthermore, a spring is fixedly connected to the side of the insert block near the slide rod. Several springs are provided in total. The end of the spring away from the insert block is fixedly connected to the inner wall of the connecting shell. The inner side of the spring is sleeved with the outer surface of the slide rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a limiting plate. The limiting plate at the bottom of the connecting frame is aligned with the pre-reserved groove on the fixed frame. The limiting plate is inserted into the fixed frame, and then bolt two is tightened in the limiting plate and the fixed frame to fix the connecting frame. Then, the MBR membrane module is placed into the connecting frame from top to bottom. By using bolt two that can be tightened in the fixed frame and the limiting plate, the MBR membrane module can be fixed inside the device. Fixing the MBR membrane module inside the device can reduce the shaking and displacement of the membrane, ensure the stability of the membrane position during operation, and avoid fluctuations in the treatment effect caused by the movement of the membrane module.

[0018] 2. This utility model incorporates insert blocks. When an insert plate is inserted into a positioning frame, the insert plate presses against the insert blocks, causing the two insert blocks to move away from each other. Simultaneously, the insert blocks drive a sliding rod to slide within the connecting housing, and also compress a spring. By securing the insert blocks within the slot, the MBR membrane module can be easily removed for cleaning. This facilitates regular membrane cleaning, removing accumulated contaminants from the membrane surface, preventing membrane pore blockage, and extending the membrane's lifespan.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 As shown, this utility model is an MBR membrane chemical fiber wastewater treatment device, including a shell 101, a top cover 102 slidably connected to the inner wall of the shell 101, a disassembly mechanism 2 and a fixing mechanism 3 provided on the top cover 102. This device fixes the membrane inside the device through the disassembly mechanism 2, and then the membrane can be easily disassembled for cleaning through the fixing mechanism 3, so as to extend the service life of the membrane.

[0031] The disassembly mechanism 2 includes a connecting block 201, a fixing block 202 slidably connected to the outer surface of the connecting block 201, a bolt 203 threadedly connected to the inner wall of the fixing block 202, and a fixing rod 204 fixedly connected to the inner wall of the top cover 102. The bolt 203 can be tightened into the fixing block 202 and the connecting block 201, thereby fixing the top cover 102 into the housing 101 and locking and sealing the device. A C-shaped buckle 205 slidably connected to the outer surface of the fixing rod 204, and a connecting frame 2 is fixedly connected to the bottom of the C-shaped buckle 205. 06. A limiting plate 207 is fixedly connected to the bottom of the connecting frame 206. A fixing frame 208 is slidably connected to the outer surface of the limiting plate 207. When the top cover 102 is installed into the housing 101, it will cause the C-shaped buckle 205 to engage with the fixing rod 204, thereby positioning the connecting frame 206. Bolt 209 is threadedly connected to the inner wall of the fixing frame 208. An MBR membrane module 210 is slidably connected to the inner wall of the connecting frame 206. Two connecting blocks 201 are provided. The outer surface of the connecting block 201 is flush with the outer surface of the top cover 102. For surface-fixed connection, bolt 209 can be tightened into the fixing frame 208 and the limiting plate 207, thereby fixing the connecting frame 206 and preventing the membrane from shifting during use. Several fixing blocks 202 are provided, with their outer surfaces fixedly connected to the outer surface of the housing 101. The outer surface of bolt 203 is rotatably connected to the inner wall of the connecting block 201. Two fixing rods 204 are provided. When the fixing blocks 202 are fixed between the connecting blocks 201, the top cover 102 is also fixed. The device can be locked and sealed. The outer surface of the fixing frame 208 is slidably connected to the inner wall of the housing 101. Two bolts 209 are provided. The outer surface of the bolts 209 is rotatably connected to the inner wall of the limiting plate 207. The top of the MBR membrane module 210 contacts the bottom of the top cover 102. After the top cover 102 is installed, it can contact the MBR membrane module 210, so that the MBR membrane module 210 is always kept in the connecting frame 206, preventing the MBR membrane module 210 from detaching from the connecting frame 206.

[0032] The fixing mechanism 3 includes a water inlet 301 fixedly connected to the inner wall of the top cover 102. A dustproof and ventilated cover 302 is snapped onto the outer surface of the water inlet 301. Limiting blocks 303 are fixedly connected to the inner wall of the housing 101. Several limiting blocks 303 are provided. The dustproof and ventilated cover 302 on the water inlet 301 can prevent dust from entering the device during wastewater treatment, thereby ensuring better quality of the treated water. Two bolts 304 are threadedly connected to the inner wall of the limiting block 303. The outer surface of the bolts 304 is rotatably connected to the inner wall of the fixing frame 208. An insert plate 305 is fixedly connected to the bottom of the fixing frame 208. Bolt 304 can be tightened into the limiting block 303. At this time, bolt 304 will also enter the fixed frame 208, thereby fixing the fixed frame 208. The outer surface of the insert plate 305 is slidably connected to the positioning frame 306. The bottom of the positioning frame 306 is fixedly connected to the inner wall of the housing 101. The insert plate 305 has a slot 307 inside. There are two slots 307. The inner wall of the slot 307 is inserted into the insert block 308. When the fixed frame 208 is installed, the positioning frame 306 guides the fixed frame 208 through the connection with the insert plate 305, thereby facilitating the subsequent fixing of the fixed frame 208.

[0033] A slide rod 309 is fixedly connected to the side of the insert block 308 away from the insert plate 305. A connecting shell 310 is slidably connected to the outer surface of the slide rod 309. The bottom of the connecting shell 310 is fixedly connected to the inner wall of the shell 101. A spring 311 is fixedly connected to the side of the insert block 308 near the slide rod 309. When the insert block 308 moves, it will also compress the spring 311, so that the spring 311 can rebound and lock the insert block 308 into the slot 307. Several springs 311 are provided. The end of the spring 311 away from the insert block 308 is fixedly connected to the inner wall of the connecting shell 310. The inner side of the spring 311 is sleeved with the outer surface of the slide rod 309. The slide rod 309 restricts the movement trajectory of the spring 311, so that the spring 311 can only move along the slide rod 309, preventing the spring 311 from tilting or deviating during the movement.

[0034] One specific application of this embodiment is:

[0035] When the equipment is needed, the staff first aligns the insert plate 305 at the bottom of the fixed frame 208 with the positioning frame 306 and inserts the insert plate 305 into the positioning frame 306. At this time, the insert plate 305 will press the insert block 308, causing the two insert blocks 308 to move away from each other. The insert block 308 will then drive the slide rod 309 to slide within the connecting shell 310. Simultaneously, the insert block 308 will also press the spring 311. When the insert plate 305 is fully inserted into the positioning frame 306, the spring 311 will rebound, causing the insert block 308 to insert into the slot 307, thus positioning the fixed frame 208. This facilitates the removal of the MBR membrane module 210 for cleaning. This facilitates regular membrane cleaning, which removes accumulated contaminants from the membrane surface, prevents pore blockage, and extends the membrane's lifespan. At this point, the fixing frame 208 will also contact the limiting block 303. Then, the bolt 304 is tightened into the limiting block 303 to fix the fixing frame 208. Next, the limiting plate 207 at the bottom of the connecting frame 206 is aligned with the pre-drilled groove on the fixing frame 208, and the limiting plate 207 is inserted into the fixing frame 208. Then, the bolt 209 is tightened into the limiting plate 207 and the fixing frame 208 to fix the connecting frame 206. Then, the MBR... The membrane module 210 is placed into the connecting frame 206 from top to bottom, which achieves the goal of fixing the MBR membrane module 210 inside the device. Fixing the MBR membrane module 210 inside the device can reduce membrane shaking and displacement, ensure the membrane's stable position during operation, and avoid fluctuations in the treatment effect caused by the movement of the membrane module. Then, the top cover 102 is clamped into the housing 101. At this time, the fixing rod 204 will be clamped into the C-shaped buckle 205, further fixing the connecting frame 206. Finally, the bolt 203 is tightened into the fixing block 202 and the connecting block 201 to fix the top cover 102.
