Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a membrane separation device for the advanced treatment of wastewater from waste paper production. Background Art

[0002] Wastewater from waste paper production refers to the wastewater generated during the recycling, treatment, and reproduction of waste paper. This kind of wastewater usually contains a large amount of organic matter, suspended solids, fibrous materials, and potentially harmful substances such as ink and dyes. If the wastewater from waste paper production is not properly treated, it will cause serious pollution to the environment and damage to the environment.

[0003] During the waste paper production process, a large amount of water is required for production. After use, this water will generate wastewater, which contains more organic matter, suspended solids, fibrous materials, etc. If directly discharged into rivers, it will pollute the water sources in the rivers. Therefore, it is necessary to treat the wastewater before discharging. Since this wastewater contains a large amount of fibrous materials, when a large amount of fibrous materials pass through the ultrafiltration membrane for filtration and separation, the fibrous materials are prone to adhere and accumulate on the surface of the ultrafiltration membrane. After a long time of separation and filtration, a large amount of fibrous materials are likely to block the surface of the ultrafiltration membrane, thereby causing a decrease in the filtration rate of the ultrafiltration membrane and affecting the filtration efficiency of the wastewater from waste paper production.

The hydrophilic sponge is provided with a plurality of adsorption grooves, and the plurality of adsorption grooves are in a strip shape. When the hydrophilic sponge is moving to clean the surface of the ultrafiltration membrane, the long strip adsorption grooves on the hydrophilic sponge adsorb a large amount of fiber materials in the sewage.

[0022] Through the aeration pipe, connecting pipe and aeration hole, gas is introduced from the aeration pipe, and a large amount of gas is discharged from the aeration hole through the connecting pipe. The gas forms a large number of bubbles in the sewage, and the bubbles rise from the bottom of the ultrafiltration membrane. The bubbles pass through the surface of the ultrafiltration membrane, and the fiber material on the surface of the ultrafiltration membrane is further pushed upward, so that the fiber material rises and is not easy to adhere to the surface of the ultrafiltration membrane, so that the ultrafiltration membrane is not easy to cause clogging, and the filtration efficiency of the ultrafiltration membrane is further improved;

[0023] The waterproof motor is set to drive the screw to rotate, the screw drives the movable plate to move up and down, the movable plate drives the adjusting plate and the soft bristles to move up and down, and at the same time, when the adjusting plate moves up and down, it drives the adjusting rod to move up and down. When the adjusting rod moves in the corrugated groove, it cooperates with the elastic part to move back and forth left and right. The adjusting rod drives the adjusting plate and the soft bristles to move back and forth left and right, so that the soft bristles move back and forth left and right when they move up and down, and the bristles further remove the fiber material on the surface of the ultrafiltration membrane to ensure the filtration efficiency of the ultrafiltration membrane.

[0038] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0040] like Figures 1-9 As shown, the present application provides a membrane separation device for deep treatment of waste paper production wastewater, including: a treatment box 1, a box cover 101 is fixedly installed on the top surface of the treatment box 1 by bolts, and a water inlet pipe 102 and a drain pipe 103 are fixedly installed on the side of the treatment box 1, and also includes:

[0041] The filter mechanism 2 is arranged inside the treatment box 1. The filter mechanism 2 includes a fixing frame 201 located on the inner wall of the treatment box 1. A plurality of ultrafiltration membranes 202 are fixedly mounted on the fixing frame 201 by bolts. A plurality of connecting pipes 208 are arranged below the ultrafiltration membranes 202. The filter mechanism 2 is used to filter waste paper wastewater;

[0042] Specifically, Figures 1-4 As shown, a support plate 203 is fixedly installed on the side of the fixing frame 201, and a water suction pipe 204 is connected to the top surface of the support plate 203 through a fixing buckle. Both sides of the water suction pipe 204 are connected to the water outlets of multiple ultrafiltration membranes 202 through multiple connecting pipes 205. One end of the water suction pipe 204 movably passes through the bottom surface of the box cover 101 and extends to the top of the box cover 101.

[0043] In this embodiment, an ultrafiltration membrane 202 is provided to filter and separate sewage, and a water suction pipe 204 is provided to suck out the filtered water from the inside of the ultrafiltration membrane 202 .

[0044] Specifically, Figures 1-4 As shown, a fixing sleeve 207 is fixedly installed on the side of the fixing frame 201, and an aeration pipe 206 is fixedly installed on the inner wall of the fixing sleeve 207. One end of the aeration pipe 206 movably passes through the bottom surface of the box cover 101 and extends to the top of the box cover 101. One end of the connecting pipe 208 is fixedly passed through the outer wall of the aeration pipe 206 and extends to the inside of the aeration pipe 206.

[0045] In this embodiment: gas is introduced through the aeration pipe 206, and the gas is discharged from the multiple aeration holes 209 through the connecting pipe 208. A large amount of gas forms bubbles and rises. When the bubbles rise, they come into contact with the surface of the ultrafiltration membrane 202, and the fiber material on the surface of the ultrafiltration membrane 202 is driven up together, thereby preventing the fiber material from blocking the ultrafiltration membrane 202.

[0046] Cleaning mechanism 3 is located on both sides of the ultrafiltration membrane 202. The cleaning mechanism 3 includes soft bristles 311 located on both sides of the ultrafiltration membrane 202. One end of the soft bristles 311 is fixedly installed with an adjusting plate 310. The cleaning mechanism 3 is used to clean the surface of the ultrafiltration membrane 202.

[0047] Specifically, as Figures 1-7 shown, two fixing blocks 301 are fixedly installed on the top surface of the ultrafiltration membrane 202. Two support frames 302 are respectively fixedly installed on the top surfaces of the two fixing blocks 301. A groove one 303 and a groove two 304 are respectively opened on the side surfaces of the support frames 302. A moving plate 308 is slidably installed on the inner wall of the groove one 303. One end of the top surface of the moving plate 308 is slidably penetrated and installed with a sliding rod 307. The other end of the top surface of the moving plate 308 is threadedly penetrated and installed with a screw rod 306. Both ends of the sliding rod 307 are fixedly connected to the upper and lower inner walls of the groove one 303.

[0048] In this embodiment: By setting the screw rod 306, the moving plate 308 is driven to rise and fall. The sliding rod 307 limits the moving plate 308. The set soft bristles 311 remove the fiber material on the surface of the ultrafiltration membrane 202.

[0049] Specifically, as Figures 1-7 shown, both ends of the screw rod 306 are rotatably connected to the inner walls of both ends of the groove one 303 through bearing seats. A waterproof motor 305 is fixedly installed on the inner wall of the groove two 304. The lower end of the output rod of the waterproof motor 305 is fixedly connected to the upper end of the screw rod 306. A moving groove 309 is opened on the side surface of the moving plate 308. The side surface of the adjusting plate 310 is slidably connected to the inner wall of the moving groove 309.

[0050] In this embodiment: By setting the waterproof motor 305 to drive the screw rod 306 to rotate, the screw rod 306 drives the moving plate 308 to move.

[0051] Specifically, as Figures 1-7 shown, a limiting rod 312 is slidably penetrated and installed on the side surface of the adjusting plate 310. Both ends of the limiting rod 312 are fixedly connected to the inner wall of the moving groove 309. An elastic member one 313 is slidably installed on the outer wall of the limiting rod 312. Both ends of the elastic member one 313 are fixedly connected to the side surface of the adjusting plate 310 and the inner wall of the moving groove 309.

[0052] In this embodiment: By setting the limiting rod 312 to limit the adjusting plate 310, the adjusting plate 310 moves more stably. The set elastic member one 313 exerts an elastic force on the adjusting plate 310.

[0053] Specifically, as Figures 1-7As shown in the figure, a limit sleeve 317 is fixedly installed on the side of the moving plate 308. An adjusting rod 315 is slidably installed on the inner wall of the limit sleeve 317. One end of the adjusting rod 315 is fixedly connected to the side of the adjusting plate 310. A through groove 314 is formed through the side of the moving plate 308. The outer wall of the adjusting rod 315 is slidably connected to the inner wall of the through groove 314. A corrugated groove 316 is formed on the side of the support frame 302. The outer wall of the other end of the adjusting rod 315 is slidably connected to the inner wall of the corrugated groove 316.

[0054] In this embodiment: through the provided corrugated groove 316, when the adjusting rod 315 moves up and down, the corrugated groove 316 drives the adjusting rod 315 to move. The provided limit sleeve 317 limits the adjusting rod 315.

[0055] An adsorption mechanism 4 is provided on both sides of the ultrafiltration membrane 202. The adsorption mechanism 4 includes hydrophilic sponges 403 located on both sides of the ultrafiltration membrane 202. One end of the hydrophilic sponge 403 is fixedly installed with a mounting block 402. The adsorption mechanism 4 is used to adsorb fibers in the sewage.

[0056] Specifically, as Figures 1-9 shown, an installation groove 401 is formed on the side of the adjusting plate 310. The inner wall of the installation groove 401 is slidably connected to the outer wall of the mounting block 402. A clamping hole 405 is formed on the top surface of the mounting block 402. A plurality of adsorption grooves 404 are formed on the surface of the hydrophilic sponge 403.

[0057] In this embodiment: through the provided hydrophilic sponge 403, the fiber material on the surface of the ultrafiltration membrane 202 is removed. The adsorption grooves 404 on the surface of the hydrophilic sponge 403 are in a strip state, so that the adsorption grooves 404 adsorb the fiber material in the sewage.

[0058] Specifically, as Figures 1-9 shown, a cavity 406 is formed inside the adjusting plate 310. A connecting plate 407 is slidably installed on the inner wall of the cavity 406. A clamping column 408 is fixedly installed on the bottom surface of the connecting plate 407. The clamping column 408 slidably penetrates the inner wall of the cavity 406 and is clamped with the clamping hole 405.

[0059] In this embodiment: through the provided clamping column 408 and clamping hole 405, the clamping column 408 can fix the clamping hole 405, so as to facilitate the fixation of the mounting block 402 and the hydrophilic sponge 403.

[0060] Specifically, as Figures 1-9 shown, a pull rod 409 is fixedly installed on the top surface of the connecting plate 407. The upper end of the pull rod 409 slidably penetrates the inner wall of the cavity 406 and extends above the adjusting plate 310. An elastic member II 410 is slidably installed on the outer wall of the pull rod 409. Both ends of the elastic member II 410 are fixedly connected to the upper inner wall of the cavity 406 and the top surface of the connecting plate 407.

[0061] In this embodiment: By providing the pull rod 409, it is convenient to pull the pull rod 409, which further drives the clamping post 408 out of the clamping hole 405, facilitating the disassembly of the mounting block 402 and the hydrophilic sponge 403 for cleaning and replacement of the hydrophilic sponge 403.

[0062] Specifically, the solution is as follows: Sewage is introduced from the water inlet pipe 102, and the ultrafiltration membrane 202 filters the sewage. Water is sucked from the water suction pipe 204. The water suction pipe 204 sucks the filtered water from inside the ultrafiltration membrane 202. A large amount of gas is blown in from the aeration pipe 206, and the gas is discharged from the aeration holes 209 through the connecting pipe 208, forming a large number of bubbles in the sewage. The bubbles rise from below the ultrafiltration membrane 202 and pass over the surface of the ultrafiltration membrane 202, further pushing up the fibrous material on the surface of the ultrafiltration membrane 202, causing the fibrous material to rise and not easily adhere and adsorb on the surface of the ultrafiltration membrane 202. The waterproof motor 305 is turned on, and the waterproof motor 305 drives the screw rod 306 to rotate. The screw rod 306 drives the moving plate 308 to move up and down. The moving plate 308 drives the adjusting plate 310 and the soft bristles 311 to move up and down. At the same time, when the adjusting plate 310 moves up and down, it drives the adjusting rod 315 to move up and down. When the adjusting rod 315 moves in the corrugated groove 316, through cooperation with the first elastic member 313, the adjusting rod 315 moves left and right reciprocally. The adjusting rod 315 drives the adjusting plate 310 and the soft bristles 311 to move left and right reciprocally. Thus, when the soft bristles 311 move up and down, they move left and right reciprocally, and the soft bristles 311 further clean the fibrous material on the surface of the ultrafiltration membrane 202. At the same time, the adjusting plate 310 drives the mounting block 402 and the hydrophilic sponge 403 to move up and down. The hydrophilic sponge 403 is provided with a plurality of adsorption grooves 404, and the plurality of adsorption grooves 404 are in a strip shape. When the hydrophilic sponge 403 moves to clean the surface of the ultrafiltration membrane 202, the strip-shaped adsorption grooves 404 on the hydrophilic sponge 403 adsorb a large amount of fibrous material in the sewage. A large amount of fibrous material is adsorbed inside the strip-shaped adsorption grooves 404, making it difficult for the fibrous material to accumulate and cover the surface of the ultrafiltration membrane 202, causing blockage of the surface of the ultrafiltration membrane 202, and ensuring the filtration efficiency and quality of the ultrafiltration membrane 202. After the operation, when the adsorption grooves 404 on the hydrophilic sponge 403 are saturated, by pulling the pull rod 409, it is convenient to disassemble, clean and replace the hydrophilic sponge 403, with relatively high efficiency.

[0063] Those of ordinary skill in the art should understand that: The discussion of any above embodiment is only exemplary; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above, which are not provided in detail for the sake of brevity.

[0064] The present invention aims to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
