Description

Technical Field

[0001] The present invention relates to the technical field of tunnel sewage treatment, and specifically relates to a waste water crystal inhibition treatment device based on electrochemistry. Background Art

[0002] Generally, the water in the tunnel drainage system comes from groundwater, mainly calcium and magnesium ions, and also contains some organic substances. These organic substances will react with metal ions to form crystals mainly composed of calcium carbonate. After long-term accumulation, it will cause the drainage system to fail. When the drainage system cannot drain normally due to crystal blockage, it will lead to an increase in the lining pressure, causing the lining to crack, affecting driving safety, and in more serious cases, it will cause the tunnel to collapse, resulting in irreparable accidents.

[0003] However, in actual use of the existing technology, the existing electrochemistry crystal inhibition device adsorbs metal ions through the cathode and anode, but the crystal accumulation on the electrode surface will reduce the electrochemistry efficiency, and it needs to be frequently cleaned manually, with high operation and maintenance costs.

[0011] Preferably, it further includes a cleaning component disposed in the deposition tube. The cleaning component includes a cleaning brush holder movably connected to the bottom of the anode frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention drives the baffle to move downward on the surface of the cathode grid through the crystal removal scraper, so that the crystal removal scraper scrapes off the crystals of metal ions such as calcium ions on the cathode grid. Since the water flow is still flowing, the scraped crystals will flow with the water flow. By setting the baffle, when the water flow impacts the crystals onto the baffle, they will be blocked by the reticulated and rough side of the baffle and transported into the interior of the deposition tube together with the crystal removal scraper, finally achieving the purpose of automatically scraping the crystals on the surface of the cathode grid and collecting the crystals; 2. The present invention also drives the movable cross to rotate through the driving tube, and makes the movable cross drive the driving piece to rotate. Since the driving piece is eccentrically arranged, when the driving piece rotates, it will drive one of the guide blocks to move along the direction of the fixed cross and stretch the return spring. Since the number of driving pieces is two and the radian of both driving pieces is 90°, when the driving piece no longer drives the guide block to move under the action of the return spring stretching and resetting, the guide block moves in the reverse direction under the action of the return spring stretching and resetting, so that the guide block drives the cleaning brush holder to reciprocate on the fixed cross. When the crystal removal scraper drives the baffle to gradually approach the cleaning brush holder, the reciprocating movement of the guide block driving the cleaning brush holder will cause the brush on the cleaning brush holder to sweep off the crystals attached to the baffle, avoiding the crystals being taken away by the water flow when the baffle carries the crystals and moves upward, thereby improving the crystal deposition efficiency of the crystals in the sewage.

A cathode grid 602 is fixedly installed on the inner wall of the anode frame 601, so that when the anode frame 601 and the cathode grid 602 are energized, calcium ions in the tunnel sewage are converted into crystals and adsorbed on the cathode grid 602; When the above structure is in use, when sewage flows from the water inlet pipe 1 through the connection cover 3 to the water outlet pipe 2, by connecting the anode frame 601 and the cathode grid 602 to the positive and negative poles of the power supply, metal ions such as calcium ions in the sewage will crystallize and adsorb on the cathode grid 602, so that metal ions such as calcium ions in the sewage crystallize in advance, avoiding the situation of pipeline blockage caused by the crystallization of metal ions such as calcium ions in the pipeline. The principle of crystal inhibition of this device is achieved by accelerating crystallization and removing crystals; The crystal removal assembly is arranged on the cathode grid 602. The crystal removal assembly includes a crystal removal scraper 701 that is movably sleeved on the surface of the cathode grid 602 and moves along the surface of the cathode grid 602. When the crystal removal scraper 701 moves downward along the direction of the cathode grid 602, the crystals adsorbed on the cathode grid 602 are scraped into the deposition tube 402. A plurality of baffles 702 are fixedly installed on the inner wall of the crystal removal scraper 701 corresponding to the position of the anode frame 601, and the water-facing surface of the baffle 702 is set to be reticulated and rough. When the water flows from the water inlet pipe 1 to the water outlet pipe 2, the crystals scraped from the cathode grid 602 by the crystal removal scraper 701 are blocked by the baffle 702 and are conveyed to the deposition tube 402 as the crystal removal scraper 701 moves. A reciprocating lead screw 703 is fixedly installed in the middle of the inner wall of the crystal removal scraper 701. The bottom of the reciprocating lead screw 703 is movably connected to a fixed sleeve 704. A driving head 705 is fixedly installed in the middle of the fixed sleeve 704.

A positioning column 707 is movably sleeved in the middle of the reciprocating lead screw 703, and the positioning column 707 is fixedly installed on the inner wall of the positioning ring 403. The positioning column 707 is of a regular polygon structure. When the fixed sleeve 704 drives the driving head 705 to rotate, under the guidance of the driving groove 706 and the restriction of the positioning column 707 on the rotation of the reciprocating lead screw 703, the reciprocating lead screw 703 moves up and down along the direction of the positioning column 707. A driving tube 708 is fixedly installed on the surface of the fixed sleeve 704. The positioning column 707 is rotatably connected to the inner wall of the driving tube 708 through a bearing. A driving column 709 is fixedly installed at the bottom of the driving tube 708. The driving column 709 is driven by a driving motor. Both the driving tube 708 and the driving column 709 are rotatably connected to the inner wall of the deposition tube 402. Helical conveying blades 710 for conveying calcium ion crystals to the bottom of the deposition tube 402 are fixedly installed on the surfaces of both the driving tube 708 and the driving column 709. An extrusion outlet is provided at the bottom of the deposition tube 402 to automatically discharge the crystals; When the above structure is in use, the driving column 709 is rotated by the driving motor, and the driving column 709 drives the driving tube 708 to rotate. The driving tube 708 drives the fixed sleeve 704 to rotate. The fixed sleeve 704 drives the reciprocating lead screw 703 to move up and down reciprocally along the direction of the positioning column 707 through the driving head 705 cooperating with the driving groove 706. The reciprocating lead screw 703 drives the crystal removal scraper 701 to move up and down on the surface of the cathode grid 602. When the crystal removal scraper 701 drives the baffle 702 to move downward on the surface of the cathode grid 602, the crystal removal scraper 701 scrapes off the crystals of metal ions such as calcium ions on the cathode grid 602. Since the water flow is still flowing, the scraped-off crystals will flow along with the water flow. By setting the baffle 702, when the water flow impacts the crystals onto the baffle 702, they will be blocked by the side of the baffle 702 with a mesh-like rough setting, and are conveyed into the interior of the sedimentation tube 402 together with the crystal removal scraper 701, finally achieving the purpose of automatically scraping the crystals on the surface of the cathode grid 602 and collecting the crystals.

[0018] It further includes an angle adjustment component arranged at one end of the connection cover 3. The angle adjustment component includes a drive shaft 501 fixedly installed at one end of one of the rotating disks 401. The drive shaft 501 movably penetrates through and extends to the outside of the connection cover 3 through a bearing. A worm gear 502 is fixedly installed on the surface of the drive shaft 501. A worm 503 is meshed with the surface of the worm gear 502. A fixed frame 504 is fixedly installed at one end of the connection cover 3 corresponding to the position of the worm gear 502, and the fixed frame 504 protects the worm gear 502 and the worm 503. The worm 503 movably penetrates through and extends to the top of the fixed frame 504 through a bearing. The worm 503 is driven by a servo motor. When the above structure is in use, the worm 503 is rotated by the servo motor, and the worm 503 drives the worm gear 502 to rotate. Then, the worm gear 502 drives the rotating disk 401 to rotate on the inner wall of the connection cover 3 through the drive shaft 501, and the rotating disk 401 drives the sedimentation tube 402 to rotate and adjust the angle between the sedimentation tube 402 and the water inlet pipe 1 and the water outlet pipe 2. By setting the sealing bellows 405, no leakage occurs when the sedimentation tube 402 rotates relative to the connection cover 3.

[0019] It further includes a cleaning assembly disposed inside the deposition tube 402. The cleaning assembly includes a cleaning brush holder 801 movably connected to the bottom of the anode frame 601. Brushes are provided at the top of the cleaning brush holder 801 corresponding to the position of the baffle 702. At the top of the surface of the driving tube 708, a fixed cross 802 is rotatably connected through a bearing, and the fixed cross 802 is fixedly installed on the inner wall of the deposition tube 402. Guide blocks 803 are fixedly installed at both the front and rear ends of the cleaning brush holder 801 corresponding to the position of the fixed cross 802. The guide blocks 803 are movably sleeved on the front and rear ends of the fixed cross 802, and a return spring 804 is provided between the guide blocks 803 and the fixed cross 802, so that the cleaning brush holder 801 moves back and forth under the guiding action of the fixed cross 802 in cooperation with the guide blocks 803, and sweeps the crystals blocked on the baffle 702. A movable cross 805 is fixedly installed on the surface of the driving tube 708 corresponding to the position of one of the guide blocks 803. Two driving pieces 806 are fixedly installed in the middle of the movable cross 805. The surface of one of the guide blocks 803 is attached to the surface of the driving piece 806. The driving piece 806 is eccentrically arranged, and the radian of the driving piece 806 is 90°, so that when the driving tube 708 drives the driving piece 806 to rotate through the movable cross 805, the driving piece 806 drives the guide block 803 to move along the direction of the fixed cross 802; When the above structure is in use, the driving tube 708 drives the movable cross 805 to rotate, and the movable cross 805 drives the driving piece 806 to rotate. The driving piece 806 drives one of the guide blocks 803 to move along the direction of the fixed cross 802. Under the action of the reset and stretching of the return spring 804, the guide block 803 drives the cleaning brush holder 801 to reciprocate on the fixed cross 802, and the brush on the cleaning brush holder 801 sweeps off the crystals attached to the baffle 702, preventing the crystals from being carried away by the water flow when the baffle 702 moves upward with the crystals, thereby improving the crystal sedimentation efficiency of the crystals in the sewage. Since the inside of the deposition tube 402 is in a slow-flow area and the water flow is slow, the crystals swept off by the cleaning brush holder 801 will slowly settle to the bottom of the deposition tube 402 and are finally extruded and discharged as the spiral conveying blade 710 rotates, thus achieving the purpose of automatically scraping off the crystals.

[0020] Working principle: When in use, when the sewage filtered by the tunnel without large impurities flows from the water inlet pipe 1 through the connecting cover 3 to the water outlet pipe 2, by connecting the anode frame 601 and the cathode grid 602 to the positive and negative poles of the power supply, metal ions such as calcium ions in the sewage will crystallize and adsorb on the cathode grid 602, causing the metal ions such as calcium ions in the sewage to crystallize in advance, and avoiding the situation that the metal ions such as calcium ions crystallize inside the pipeline and cause pipeline blockage; When there is a large accumulation of crystals on the cathode grid 602, the driving column 709 is rotated by the driving motor, and the driving column 709 drives the driving tube 708 to rotate. When the driving tube 708 rotates, the driving tube 708 drives the fixed sleeve 704 to rotate. Since the positioning column 707 is fixedly installed with the positioning ring 403, that is, the positioning column 707 remains relatively stationary with the deposition tube 402. At this time, when the driving tube 708 drives the fixed sleeve 704 to rotate, the fixed sleeve 704 drives the reciprocating lead screw 703 to reciprocate up and down along the direction of the positioning column 707 through the driving head 705 and the driving groove 706. When the reciprocating lead screw 703 reciprocates up and down, the reciprocating lead screw 703 drives the crystal removal scraper 701 to move up and down on the surface of the cathode grid 602; When the crystal removal scraper 701 drives the baffle 702 to move downward on the surface of the cathode grid 602, the crystal removal scraper 701 scrapes off the crystals of metal ions such as calcium ions on the cathode grid 602. Since the water flow is still flowing, the scraped crystals will flow with the water flow. By setting the baffle 702, when the water flow impacts the crystals onto the baffle 702, they will be blocked by the rough mesh side of the baffle 702 and move downward together with the crystal removal scraper 701; When the driving tube 708 rotates, the driving tube 708 drives the movable cross 805 to rotate, and the movable cross 805 drives the driving piece 806 to rotate. Since the driving piece 806 is eccentrically arranged, when the driving piece 806 rotates, it drives one of the guide blocks 803 to move along the direction of the fixed cross 802 and stretches the return spring 804. Since the number of driving pieces 806 is two and the radian of both driving pieces 806 is 90°, when the driving piece 806 no longer drives the guide block 803 to move under the action of the reset and stretching of the return spring 804, the guide block 803 moves in the reverse direction under the action of the reset and stretching of the return spring 804, so that the guide block 803 drives the cleaning brush holder 801 to reciprocate on the fixed cross 802. When the crystal removal scraper 701 drives the baffle 702 to gradually approach the cleaning brush holder 801, the reciprocating movement of the cleaning brush holder 801 driven by the guide block 803 causes the brush on the cleaning brush holder 801 to sweep off the crystals attached to the baffle 702, preventing the crystals from being carried away by the water flow when the baffle 702 moves upward with the crystals, thereby improving the crystal settling efficiency of the crystals in the sewage. Since the inside of the deposition tube 402 is in a slow flow area and the water flow is slow, the crystals swept off by the cleaning brush holder 801 will slowly settle to the bottom of the deposition tube 402 and are finally extruded and discharged with the rotation of the spiral conveyor blade 710, thus achieving the purpose of automatically scraping off the crystals; When adjusting the tilt angles of the deposition tube 402, the anode frame 601, and the cathode grid 602 according to the flow rate or flow volume, at this time, the servo motor is driven to rotate the worm 503, and the worm 503 drives the worm wheel 502 to rotate. Furthermore, the worm wheel 502 drives the rotating disk 401 to rotate on the inner wall of the connecting cover 3 through the drive shaft 501, and the rotating disk 401 drives the deposition tube 402 to rotate and adjust the angle between the water inlet pipe 1 and the water outlet pipe 2. By providing the sealing bellows 405, no leakage occurs when the deposition tube 402 rotates relative to the connecting cover 3.
