Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a reverse osmosis membrane sewage treatment device. Background Art

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane that separates solvents and solutes through the driving force of a pressure difference. The reverse osmosis membrane is an artificial material that mimics biological semi-permeable membranes and has selective permeability, allowing water molecules to pass through while retaining macromolecular substances such as dissolved salts, colloids, and microorganisms. Under the action of a pressure higher than the osmotic pressure of the solution, the solvent passes through the membrane layer against the concentration gradient, while the solute is retained. This reverse osmosis process requires energy consumption.

[0003] When existing sewage enters the reverse osmosis membrane, the sewage contains a large amount of impurities such as dissolved salts, colloids, and precipitates. Therefore, it is necessary to treat the sewage to improve the treatment effect of the reverse osmosis membrane on sewage. However, most of the existing sewage treatment methods are carried out through equipment such as filters, grit chambers, and flotation tanks, and the treatment efficiency of this treatment method is very slow.

[0021] Specifically, it should be noted here that the control console 102 and the drive motor 309 are electrically connected through wires. The specific working principle between them is cited through the existing technology and will not be elaborated too much here.

[0022] As an implementation method in this embodiment, the shaking component includes an arm plate 3 fixedly connected to the other end of the main shaft 105. A guide groove 301 is formed on the arm plate 3. Inside the guide groove 301, a pulley 302 is slidably connected. The pulley 302 is rotatably connected to a disk 303.

A transmission belt 306 is sleeved between the first belt pulley 305 and the second belt pulley 307. The second belt pulley 307 is fixedly connected to one end of a drive rod 308. The other end of the drive rod 308 is fixedly connected to the output end of a drive motor 309. The drive motor 309 is fixedly installed on the bottom plate 103.

[0023] Specifically, the sewage and the additive are added into the interior of the treatment cylinder 107 through the water inlet pipe 108, and then the drive motor 309 is operated. The operation of the drive motor 309 facilitates the rotation of the drive rod 308. A second pulley 307 is fixedly connected to the drive rod 308. The rotation of the drive rod 308 drives the second pulley 307 to rotate. The rotation of the second pulley 307 drives the first pulley 305 to rotate through the transmission belt 306, thereby facilitating the rotation of the transmission rod 304 on the first pulley 305. Discs 303 are fixedly connected to both ends of the transmission rod 304. The rotation of the transmission rod 304 drives the discs 303 to rotate. The rotation of the discs 303 causes the pulleys 302 to slide inside the guide grooves 301, thereby facilitating the arm plate 3 to drive the main shaft 105 to rotate, causing the treatment cylinder 107 to shake back and forth, and increasing the full mixing between the sewage and the additive inside the treatment cylinder 107.

[0024] As an implementation manner in this embodiment, the filtering assembly includes a bracket 4 fixedly connected to the top surface position of the device body 1. Slide rods 401 are fixedly connected to both ends of the bracket 4. The other ends of the slide rods 401 are fixedly connected to shaft seats 402. The bottom ends of the shaft seats 402 are fixedly connected to the device body 1. A socket 403 is slidably connected to the slide rods 401. The top end of the socket 403 is slidably connected to a load-bearing plate 404. A frame 405 is fixedly installed on the load-bearing plate 404. A filter plate 406 is installed inside the frame 405. One end of the load-bearing plate 404 is fixedly connected to an adjustment block 407. A through groove 408 is formed in the adjustment block 407. A driven block 409 is slidably connected inside the through groove 408. One end of the driven block 409 is fixedly connected to a clamping block 410. The clamping block 410 is arranged inside the adjustment block 407. The bottom surface of the clamping block 410 is attached to the surface position of the slide rod 401. A top block 411 is fixedly connected to the top end of the clamping block 410. An arc-shaped groove 412 is formed in the top surface position of the top block 411. A cam 413 is attached to the inner wall of the arc-shaped groove 412. The cam 413 is fixedly connected to the middle end position of a rotating shaft 414. Grips 415 are fixedly connected to both ends of the rotating shaft 414.

[0025] Specifically, the mixed sewage inside the treatment cylinder 107 is discharged into the interior of the frame 405 through the water outlet pipe 109. The sewage is secondary-treated by the filter plate 406. The treated sewage is discharged through the water passing plate 101. When it is necessary to move the position of the frame 405, the grip 415 is pulled upward. The pulling of the grip 415 causes the rotating shaft 414 to rotate. The rotation of the rotating shaft 414 causes the cam 413 to disengage from the interior of the arc-shaped groove 412. Then, the frictional force between the clamping block 410 at the bottom end of the top block 411 and the slide rod 401 is reduced, thereby facilitating the movement of the position of the frame 405.

[0026] As an implementation manner in this embodiment, the scraping assembly includes guide rails 5 fixedly connected to both sides of the frame 405. A slider 501 is slidably connected to the guide rails 5. The slider 501 is fixedly connected to a bracket 502. A handle 503 is fixedly connected to the top end of the bracket 502. A side plate 504 is fixedly connected to the middle position of the bracket 502. Limiting blocks 505 are movably inserted at both ends of the side plate 504. A scraping plate 506 is fixedly connected to the bottom end of the limiting block 505. A spring 507 is sleeved on the limiting block 505. A pull rod 508 is fixedly connected to the middle position of the top surface of the scraping plate 506. The top end of the pull rod 508 is movably inserted into a hinge seat 509. A pressure rod 510 is movably connected to the hinge seat 509. The middle end of the pressure rod 510 is rotatably connected to a limiting seat 511. The limiting seat 511 is fixedly connected to the middle position of the top surface of the bracket 502.

[0027] Specifically, when it is necessary to scrape the impurities filtered on the filter plate 406, first press down the pressure rod 510. Then, the hinge seat 509 at the other end of the pressure rod 510 will pull up the pull rod 508. Then, the scraping plate 506 will separate from the surface of the filter plate 406. Then, push the handle 503. The pushing of the handle 503 causes the slider 501 on the bracket 502 to slide on the guide rail 5, moving the bracket 502 to the other side of the frame 405. Then, release the pressure rod 510. The elastic force of the spring 507 makes the scraping plate 506 fit on the filter plate 406. By pulling the handle 503, the scraping plate 506 scrapes the impurities on the surface of the filter plate 406.

[0028] The working principle of the present invention: Sewage and additives are added into the interior of the treatment cylinder 107 through the water inlet pipe 108. Then, the drive motor 309 operates. The operation of the drive motor 309 facilitates the rotation of the drive rod 308. A second pulley 307 is fixedly connected to the drive rod 308. The rotation of the drive rod 308 drives the second pulley 307 to rotate. The rotation of the second pulley 307 drives the first pulley 305 to rotate through the transmission belt 306. Thus, it is convenient for the transmission rod 304 on the first pulley 305 to rotate. Discs 303 are fixedly connected to both ends of the transmission rod 304. The rotation of the transmission rod 304 drives the discs 303 to rotate. The rotation of the discs 303 makes the pulleys 302 slide inside the guide grooves 301. Thus, it is convenient for the arm plate 3 to drive the main shaft 105 to rotate, causing the treatment cylinder 107 to sway back and forth, increasing the full mixing between the sewage and additives inside the treatment cylinder 107; The mixed sewage inside the treatment cylinder 107 is discharged into the interior of the frame 405 through the water outlet pipe 109. The sewage is secondary-treated by the filter plate 406, and the treated sewage is discharged through the water passing plate 101. When it is necessary to move the position of the frame 405, the grip 415 is pulled upward. The pulling of the grip 415 causes the rotating shaft 414 to rotate. The rotation of the rotating shaft 414 causes the cam 413 to disengage from the interior of the arc-shaped groove 412. Then, the frictional force between the clamp 410 at the bottom end of the top block 411 and the sliding rod 401 is reduced, facilitating the movement of the position of the frame 405. When it is necessary to scrape the impurities filtered on the filter plate 406, first, the pressure rod 510 is pressed down. Then, the hinge seat 509 at the other end of the pressure rod 510 will pull up the pull rod 508. Then, the scraper 506 will disengage from the surface of the filter plate 406. Then, the handle 503 is pushed. The pushing of the handle 503 causes the slider 501 on the bracket 502 to slide on the guide rail 5, moving the bracket 502 to the other side of the frame 405. Then, the pressure rod 510 is released. The elastic force of the spring 507 causes the scraper 506 to fit on the filter plate 406. By pulling the handle 503, the scraper 506 scrapes the impurities on the surface of the filter plate 406.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
