A clog-resistant MBR membrane module

Abstract

This utility model discloses an anti-clogging MBR membrane module, relating to the field of wastewater treatment technology. It includes a mechanism box, with two vertically distributed vibration tables fixedly connected to the upper and lower sides of the inner side of the mechanism box. A moving mechanism is fixedly connected to one side of the vibration tables that is close to each other. Several horizontally distributed MBR membrane bodies are fixedly connected to the middle of the moving mechanism. A discharge mechanism is fixedly connected to the lower side of the mechanism box near the left and right sides. An outlet is fixedly connected to the middle of the right side of the mechanism box. In this anti-clogging MBR membrane module, a first motor drives a winding wheel to rotate, causing the left and right traction ropes to converge and extend from the winding wheel, respectively. This causes the slide block to slide on the slide table. When the MBR membrane bodies vibrate, causing debris to fall off, the individual MBR membrane bodies can quickly separate, preventing interference with the falling debris.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an anti-clogging MBR membrane module. Background Technology

[0002] A membrane bioreactor (MBR) is a novel wastewater treatment device that combines ultrafiltration and microfiltration membrane separation technology with biological treatment in wastewater treatment. MBR utilizes ultrafiltration and microfiltration membranes to trap microbial flocs and larger organic molecules in the activated sludge mixture, retaining them within the reactor. This results in a high biological concentration and extends the residence time of organic solids, significantly improving the degradation efficiency of organic matter by microorganisms. The effluent treated by ultrafiltration and microfiltration membranes is of high quality and can be directly reused for non-potable water.

[0003] Chinese patent document CN212924541U discloses a fouling-resistant MBR curtain membrane module, including a membrane frame, MBR curtain membrane sheets, and an aeration device. A vibration and rotation device is also provided at the center of the membrane frame. The vibration and rotation device includes an upper device and a lower device. The lower device is located on the aeration device, and the upper device is located at the top of the membrane frame and communicates with the outlet. Both the upper and lower devices include a stepped vibration pad and a rotation device. The rotation device includes a sliding device and an air pressure passage. The sliding device is pushed by the air pressure passage. This allows the MBR curtain membrane sheets to be moved from a fixed position to a position that vibrates up and down and sways at an angle during aeration, solving the problem of sludge adhering and not easily detaching. This significantly enhances the fouling resistance of the MBR curtain membrane sheets and reduces operating energy consumption.

[0004] The existing technology has the following problems:

[0005] The component uses airflow to move the slider within the groove, but this causes the bottom of the MBR membrane to stick together, making it difficult for shaken debris to fall downwards. Also, when not needed, the slider is easily affected by water flow and moves on its own, making it difficult to fix the position of the MBR membrane. Utility Model Content

[0006] This invention provides an anti-clogging MBR membrane module to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A clog-resistant MBR membrane module includes a mechanism box. Two vibrating tables are fixedly connected to the upper and lower sides of the inner side of the mechanism box. A moving mechanism is fixedly connected to the side of the vibrating tables that are close to each other. Several horizontally distributed MBR membrane bodies are fixedly connected to the middle of the moving mechanism. A discharge mechanism is fixedly connected to the lower side of the mechanism box near the left and right sides. An outlet is fixedly connected to the middle of the right side of the mechanism box.

[0009] The moving mechanism includes a slide table. The slide table is fixedly connected to the front and rear sides of the vibration table on the same side, with four slide tables arranged in a rectangular pattern. Several laterally distributed slide blocks are slidably connected to the inner sides of each of the four slide tables. Pull rods are fixedly connected to the front and rear sides of each slide block. The upper and lower sides of the MBR membrane body are movably mounted on the slide blocks away from the vibration table, near the front and rear sides. Traction ropes are fixedly connected to the front and rear sides of the four leftmost slide blocks. Winding wheels are wound around the outer sides of the traction ropes near the upper side. The front and rear sides of the winding wheels are rotatably connected to the upper side of the mechanism box near the left and right sides. Two first motors, arranged left and right, are fixedly connected to the upper side of the mechanism box near the left and right sides. Transmission rods are fixedly connected to the output ends of the two first motors. The inner side of the outermost winding wheel is fixedly connected to the outer side of the transmission rod. Gears are fixedly connected to the sides of the winding wheels away from the first motors.

[0010] Preferably, rubber pads are fixedly connected to both sides of several of the slides.

[0011] Preferably, a sixteen rectangular sealing components are rotatably connected to the upper side of the mechanism box near the four corners. Each sealing component includes a rotating sleeve, the lower side of which is rotatably connected to the upper side of the mechanism box near the four corners. A movable sleeve is movably fitted inside the rotating sleeve, and an electric push rod is rotatably connected to the outer side of the rotating sleeve. The side of the electric push rod away from the movable sleeve is rotatably connected to the upper side of the mechanism box near the four corners. The outer side of the traction rope is movably fitted inside the movable sleeve. A plurality of annularly distributed clamping blocks are slidably connected to the lower side of the movable sleeve. A rubber sleeve is fixedly connected to the side of each clamping block near the traction rope, and the outer side of each clamping block is slidably connected to the inner side of the upper wall of the mechanism box.

[0012] Preferably, the inner side of the traction rope is made of steel cable, and the outer side is made of rubber.

[0013] Preferably, the material discharge mechanism includes a conveyor belt, the outer front and rear sides of the conveyor belt are movably installed on the inner front and rear sides of the mechanism box near the bottom, and two receiving boxes distributed on the left and right sides are fixedly connected to the lower side of the mechanism box near the left and right sides, and a box cover is movably installed on the front side of each of the two receiving boxes.

[0014] Preferably, a second motor is fixedly connected to the rear side of each of the two receiving boxes, and an auger is fixedly connected to the output end of each of the two second motors, with the outer side of the auger movably sleeved on the inner side of the receiving box.

[0015] Preferably, two guide plates are fixedly connected to the inner front and rear sides of the mechanism box near the bottom.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

This allows the individual MBR membrane bodies to quickly separate when the MBR membrane body vibrates and debris falls off, preventing any impact from the falling debris.

[0018] This utility model provides an anti-clogging MBR membrane module, which uses a discharge mechanism, conveyor belt, receiving box, box cover, second motor, auger and guide plate to cooperate. The conveyor belt transports the fallen debris to the receiving boxes on the left and right sides, so that the auger can quickly discharge the debris, which facilitates the operation of cleaning the debris after filtration inside the mechanism box.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, an anti-clogging MBR membrane module includes a mechanism box 1. Two vibrating tables 2 are fixedly connected to the upper and lower sides of the inner side of the mechanism box 1. A moving mechanism 3 is fixedly connected to the side of the vibrating tables 2 that is close to each other. Several horizontally distributed MBR membrane bodies 4 are fixedly connected to the middle of the moving mechanism 3. A discharge mechanism 5 is fixedly connected to the lower side of the mechanism box 1 near the left and right sides. An outlet 6 is fixedly connected to the middle of the right side of the mechanism box 1.

[0028] The moving mechanism 3 includes a slide table 31. The slide table 31 is fixedly connected to the front and rear sides of the vibration table 2 on the side closest to each other, with four slide tables 31 arranged in a rectangle. Several horizontally distributed slide blocks 32 are slidably connected to the inner side of each of the four slide tables 31. Pull rods 33 are fixedly connected to the front and rear sides of each slide block 32. The upper and lower sides of the MBR membrane body 4 are movably mounted on the side of the slide block 32 away from the vibration table 2, near the front and rear sides. Traction ropes 35 are fixedly connected to the front and rear sides of the four leftmost slide blocks 32. Sixteen traction ropes 35 are all wound with winding wheels 34 on the outer side near the upper side. The front and rear sides of the winding wheels 34 are rotatably connected to the upper side of the mechanism box 1 near the left and right sides. Two first motors 37 are fixedly connected to the upper side of the mechanism box 1 near the left and right sides. The output ends of the two first motors 37 are all fixedly connected with transmission rods 38. The inner side of the outermost winding wheel 34 is fixedly connected to the outer side of the transmission rod 38. Gears 36 are fixedly connected to the side of several winding wheels 34 away from the first motors 37.

[0029] It should be noted that the first motor 37 drives the transmission rod 38 to rotate. When the transmission rod 38 rotates, it drives the outer winding wheel 34 to rotate. The gear 36 makes all the winding wheels 34 rotate synchronously. When the winding wheel 34 rotates, the traction rope 35 is tightened or extended on the winding wheel 34. When the left traction rope 35 tightens and the right traction rope 35 extends, the slide 32 moves to the left on the slide table 31. The pull rod 33 makes all the slides 32 move at the same time, and all the MBR membrane bodies 4 are also separated from each other.

[0030] like Figure 4 As shown, rubber pads are fixedly connected to both sides of several slides 32.

[0031] It should be noted that the rubber pads are used to avoid rigid contact between the slides 32, and to prevent the slides 32 from being too tightly fitted together when all the MBR membrane bodies 4 are attached to each other, which would cause the components to deform.

[0032] like Figure 5 As shown, a sixteen rectangular sealing components 39 are rotatably connected to the upper side of the mechanism box 1 near the four corners. Each sealing component 39 includes a rotating sleeve 392. The lower side of the rotating sleeve 392 is rotatably connected to the upper side of the mechanism box 1 near the four corners. A movable sleeve 393 is movably sleeved on the inner side of the rotating sleeve 392. An electric push rod 391 is rotatably connected to the outer side of the rotating sleeve 392. The side of the electric push rod 391 away from the movable sleeve 393 is rotatably connected to the upper side of the mechanism box 1 near the four corners. The outer side of the traction rope 35 is movably sleeved on the inner side of the movable sleeve 393. Several ring-shaped clamping blocks 394 are slidably connected to the lower side of the movable sleeve 393. A rubber sleeve 395 is fixedly connected to the side of the clamping block 394 near the traction rope 35. The outer side of the clamping block 394 is slidably connected to the inner side of the upper wall of the mechanism box 1.

[0033] It should be noted that the electric push rod 391 drives the rotating sleeve 392 to rotate. The inner side of the rotating sleeve 392 is provided with a spiral groove, so that when the rotating sleeve 392 rotates, it drives the moving sleeve 393 to move up and down. The outer side of the clamping block 394 is conical. When the moving sleeve 393 moves down and drives the clamping block 394 to move down, the clamping block 394 pushes the rubber sleeves 395 closer together, so that the rubber sleeves 395 are tightly attached to the outer side of the traction rope 35, thereby sealing the traction rope 35 and the mechanism box 1.

[0034] like Figure 3 As shown, the inner side of the traction rope 35 is made of steel cable, and the outer side is made of rubber.

[0035] It should be noted that the material of the traction rope 35 not only enhances its own strength, but also facilitates the sealing effect of the clamping block 394 on the traction rope 35. At the same time, a hydrophobic layer can be easily applied to the outside of the traction rope 35, so that the traction rope 35 will not carry water out when it is removed from the inside of the mechanism box 1.

[0036] like Figure 6 As shown, the material discharge mechanism 5 includes a conveyor belt 51. The outer front and rear sides of the conveyor belt 51 are movably installed on the inner front and rear sides of the mechanism box 1 near the bottom. Two receiving boxes 52 distributed on the left and right sides are fixedly connected to the lower side of the mechanism box 1 near the left and right sides. The front side of each receiving box 52 is movably installed with a box cover 53.

[0037] It should be noted that the overall structure of the conveyor belt 51 is ︹-shaped, with its two sides extending into the inside of the receiving box 52. The receiving box 52 has brushes attached to the bottom of both sides of the conveyor belt 51 near the top, so that when the conveyor belt 51 moves debris into the receiving box 52, the brushes will sweep off the debris attached to the conveyor belt 51.

[0038] like Figure 6 As shown, a second motor 54 is fixedly connected to the rear side of each of the two receiving boxes 52, and an auger 55 is fixedly connected to the output end of each of the two second motors 54. The outer side of the auger 55 is movably sleeved on the inner side of the receiving box 52.

[0039] It should be noted that the second motor 54 drives the auger 55 to rotate, which causes the auger 55 to move the debris in the receiving box 52 forward, so that the debris is removed from the inside of the receiving box 52.

[0040] like Figure 6 As shown, two guide plates 56 are fixedly connected to the inner front and rear sides of the mechanism box 1 near the bottom.

[0041] It should be noted that the guide plate 56 is used to guide the inside of the mechanism box 1 so that the debris falls onto the conveyor belt 51 as much as possible.

[0042] The working principle of this utility model is as follows: First, the first motor 37 drives the transmission rod 38 to rotate. When the transmission rod 38 rotates, it drives the outer winding wheel 34 to rotate. The gear 36 makes all the winding wheels 34 rotate synchronously. When the winding wheels 34 rotate, the traction rope 35 tightens or extends on the winding wheels 34. When the left traction rope 35 tightens and the right traction rope 35 extends, the slide block 32 moves to the left on the slide table 31. The pull rod 33 causes all the slide blocks 32 to move simultaneously, and all the MBR membrane bodies 4 also separate from each other. The electric push rod 3... 91 drives the rotating sleeve 392 to rotate. The inner side of the rotating sleeve 392 is provided with a spiral groove, so that when the rotating sleeve 392 rotates, it drives the moving sleeve 393 to move up and down. The outer side of the clamping block 394 is conical. When the moving sleeve 393 moves down and drives the clamping block 394 to move down, the clamping block 394 pushes the rubber sleeve 395 closer together, so that the rubber sleeve 395 is tightly against the outer side of the traction rope 35, thereby sealing the traction rope 35 and the mechanism box 1. The first motor 37 drives the winding wheel 34 to rotate, so that the left traction rope 35 and the right traction rope 35 are connected. One component is wound on the winding wheel 34, and the other extends from the winding wheel 34, causing the slide block 32 to slide on the slide table 31. This allows the MBR membrane bodies 4 to quickly separate when vibration causes debris to fall off, preventing any impact on the debris's fall. Finally, the guide plate 56 guides the inner side of the mechanism box 1, ensuring that as much debris as possible falls onto the conveyor belt 51. The second motor 54 drives the auger 55 to rotate, causing the auger 55 to move the debris in the receiving box 52 forward, causing the debris to fall from the receiving box. The inside of the receiving box 52 is cleaned. The overall structure of the conveyor belt 51 is ︹-shaped, with its two sides extending out of the inside of the receiving box 52. The inside of the receiving box 52 is equipped with brushes near the top, which are attached to the bottom of both sides of the conveyor belt 51. When the conveyor belt 51 moves the debris into the receiving box 52, the brushes sweep off the debris attached to the conveyor belt 51. The conveyor belt 51 then transports the fallen debris into the receiving boxes 52 on the left and right sides, allowing the auger 55 to quickly discharge the debris. This facilitates the cleaning of the debris filtered inside the mechanism box 1.
