[0002] Usually, the water in the tunnel drainage system comes from groundwater, which is mainly composed of calcium and magnesium ions, and also contains some organic matter. These organic matter 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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-9 The present invention provides a technical solution: an electrochemical wastewater crystal suppression treatment device, comprising:

[0035] A water inlet pipe 1 and a water outlet pipe 2, with a connecting cover 3 fixedly installed between the water inlet pipe 1 and the water outlet pipe 2;

[0036] The deposition assembly is arranged at the bottom of the connection cover 3. The deposition assembly includes two rotating disks 401 that are rotatably connected to the inner wall of the connection cover 3. A deposition tube 402 is fixedly installed at the bottom of the rotating disk 401, and a dynamic seal is formed between the deposition tube 402 and the rotating disk 401. The two rotating disks 401 are respectively rotatably connected to the front and rear ends of the inner wall of the connection cover 3. An opening is provided at the bottom of the connection cover 3 corresponding to the position of the deposition tube 402, and the deposition tube 402 is connected to the interior of the connection cover 3 through the opening. A sealing bellows is fixedly installed at the bottom of the connection cover 3 405, and the sealing bellows 405 is fixedly installed on the surface of the deposition tube 402, so that when the deposition tube 402 rotates around the rotating disk 401, the connection position between the deposition tube 402 and the connection cover 3 does not leak. A positioning ring 403 is fixedly installed in the middle of the top of the deposition tube 402, and a positioning groove 404 is opened on the inner wall of the connection cover 3 corresponding to the position of the positioning ring 403, and the positioning ring 403 is rotatably connected to the inner wall of the positioning groove 404, so that the positioning ring 403 cooperates with the positioning groove 404 to guide the rotation of the deposition tube 402;

[0037] An electrochemical crystallization assembly is provided between the two rotating disks 401. The electrochemical crystallization assembly includes a plurality of anode frames 601 fixedly mounted between the two rotating disks 401. The anode frames 601 are fixedly mounted on the inner wall of the deposition tube 402. A cathode grid 602 is fixedly mounted on the inner wall of the anode frame 601. When the anode frame 601 and the cathode grid 602 are energized, calcium ions in the tunnel sewage are converted into crystals that are adsorbed on the cathode grid 602.

[0038] When the above structure is in use, when sewage 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, the calcium ions and other metal ions in the sewage will be crystallized and adsorbed on the cathode grid 602, so that the calcium ions and other metal ions in the sewage will crystallize in advance, avoiding the crystallization of calcium ions and other metal ions inside the pipe, causing the pipe to be blocked. The principle of crystal suppression of this device is achieved by accelerating crystallization and removing crystals;

[0039] The decrystalline assembly is arranged on the cathode grid 602, and the decrystalline assembly includes a decrystalline scraper 701 that is movably sleeved on the surface of the cathode grid 602 and moves along the surface of the cathode grid 602, so that when the decrystalline 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. The inner wall of the decrystalline scraper 701 corresponding to the position of the anode frame 601 is fixedly installed with multiple baffles 702, and the water-facing surface of the baffle 702 is a mesh-like rough setting so that the crystals adsorbed on the cathode grid 602 are scraped into the deposition tube 402. As the water flows from the water inlet pipe 1 to the water outlet pipe 2, the crystals scraped off by the decrystalline scraper 701 on the cathode grid 602 are blocked by the baffle 702 and transported to the deposition tube 402 as the decrystalline scraper 701 moves. A reciprocating screw rod 703 is fixedly installed in the middle of the inner wall of the decrystalline scraper 701. The bottom of the reciprocating screw rod 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 driving groove 706 is opened on the surface of the reciprocating screw rod 703, and the driving head 705 is movably connected to the fixed sleeve 704. The inner wall of the driving groove 706 is connected to the middle of the reciprocating screw rod 703, and the positioning column 707 is fixedly installed on the inner wall of the positioning ring 403. The positioning column 707 is a regular polygonal structure, so that when the fixed sleeve 704 drives the driving head 705 to rotate, the reciprocating screw rod 703 will move up and down along the direction of the positioning column 707 under the guidance of the driving groove 706 and the positioning column 707 to limit the rotation of the reciprocating screw rod 703. The surface of the fixed sleeve 704 is fixedly installed with a driving tube 707. 08, the positioning column 707 is rotatably connected to the inner wall of the driving tube 708 through a bearing, and 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. The driving tube 708 and the driving column 709 are both rotatably connected to the inner wall of the deposition tube 402. The surfaces of the driving tube 708 and the driving column 709 are fixedly installed with spiral conveying blades 710 for conveying calcium ion crystals to the bottom of the deposition tube 402. An extrusion port is provided at the bottom of the deposition tube 402 to automatically discharge the crystals.

[0040] When the above structure is in use, the driving motor drives the driving column 709 to rotate, and the driving column 709 drives the driving tube 708 to rotate, and the driving tube 708 drives the fixed sleeve 704 to rotate, and the fixed sleeve 704 drives the reciprocating screw rod 703 to move up and down along the direction of the positioning column 707 through the driving head 705 and the driving groove 706. The reciprocating screw rod 703 drives the decrystalline scraper 701 to move up and down on the surface of the cathode grid 602. When the decrystalline scraper 701 drives the baffle 702 on the surface of the cathode grid 602 When the surface moves downward, the crystallization scraper 701 will scrape 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 hits the baffle 702, it will be blocked by the rough mesh surface of the baffle 702 and transported to the inside of the deposition tube 402 together with the crystallization scraper 701, finally completing the purpose of automatically scraping off the crystals on the surface of the cathode grid 602 and collecting the crystals.

[0041] The connecting cover 3 further includes an angle adjustment assembly disposed at one end thereof. The angle adjustment assembly includes a drive shaft 501 fixedly mounted on one end of one of the rotating disks 401. The drive shaft 501 movably penetrates and extends to the outside of the connecting cover 3 via a bearing. A worm gear 502 is fixedly mounted on the surface of the drive shaft 501. A worm 503 is meshed with the surface of the worm gear 502. A fixing bracket 504 is fixedly mounted on the end of the connecting cover 3 corresponding to the worm gear 502. The fixing bracket 504 protects the worm gear 502 and the worm 503. The worm 503 movably penetrates and extends to the top of the fixing bracket 504 via a bearing. The worm 503 is driven by a servo motor.

[0042] When the above structure is in use, the servo motor drives the worm 503 to rotate, and the worm 503 drives the worm wheel 502 to rotate, and then the worm wheel 502 drives the rotating disk 401 to rotate on the inner wall of the connecting cover 3 through the driving shaft 501, and the rotating disk 401 drives the sedimentation tube 402 to rotate and adjust the angle between it 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 connecting cover 3.

[0043] The cleaning assembly is also provided in the deposition tube 402, and the cleaning assembly includes a cleaning brush holder 801 movably connected to the bottom of the anode frame 601, and a brush is provided on the top of the cleaning brush holder 801 corresponding to the position of the baffle 702. The top of the surface of the driving tube 708 is rotatably connected to a fixed cross 802 through a bearing, and the fixed cross 802 is fixedly installed on the inner wall of the deposition tube 402. The front and rear ends of the cleaning brush holder 801 corresponding to the position of the fixed cross 802 are respectively fixedly installed with guide blocks 803, and the guide blocks 803 are movably sleeved on the front and rear ends of the fixed cross 802, and a reset spring 804 is provided between the guide block 803 and the fixed cross 802 to make the cleaning brush The brush holder 801 moves back and forth under the guidance of the fixed cross 802 and the guide block 803, and cleans the crystals blocked on the baffle 702. A movable cross 805 is fixedly installed on the surface of the drive tube 708 corresponding to the position of one of the guide blocks 803. Two drive plates 806 are fixedly installed in the middle of the movable cross 805. The surface of one of the guide blocks 803 is in contact with the surface of the drive plate 806. The drive plate 806 is eccentrically arranged, and the curvature of the drive plate 806 is 90°. When the drive tube 708 drives the drive plate 806 to rotate through the movable cross 805, the drive plate 806 drives the guide block 803 to move along the direction of the fixed cross 802.

[0044] When the above structure is in use, the movable cross 805 is driven to rotate by the driving tube 708, and the movable cross 805 drives the driving plate 806 to rotate. The driving plate 806 will drive one of the guide blocks 803 to move along the direction of the fixed cross 802, and under the action of the reset stretching of the reset spring 804, the guide block 803 drives the cleaning brush holder 801 to move back and forth on the fixed cross 802, and the brush on the cleaning brush holder 801 will sweep off the crystals attached to the baffle 702, so as to prevent the baffle 702 from carrying the crystals and being carried away by the water flow when moving upward, thereby improving the crystal sedimentation efficiency of the crystals in the sewage. Since the interior of the sedimentation 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 sedimentation tube 402, and are finally squeezed out as the spiral conveying blade 710 rotates, thereby achieving the purpose of automatically scraping off the crystals.

[0045] Working principle: When in use, the invention filters the sewage without large impurities through the tunnel and 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, the calcium ions and other metal ions in the sewage will be crystallized and adsorbed on the cathode grid 602, so that the calcium ions and other metal ions in the sewage will crystallize in advance, avoiding the crystallization of the calcium ions and other metal ions inside the pipe, which will cause the pipe to be blocked.

[0046] When a large amount of crystals accumulate on the cathode grid 602, the driving motor drives the driving column 709 to rotate, 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 and the deposition tube 402 remain relatively stationary, when the driving tube 708 drives the fixed sleeve 704 to rotate, the fixed sleeve 704 drives the reciprocating screw 703 to move back and forth along the direction of the positioning column 707 through the driving head 705 and the driving slot 706. When the reciprocating screw 703 moves back and forth up and down, the reciprocating screw 703 drives the decrystalline scraper 701 to move up and down on the surface of the cathode grid 602.

[0047] When the decrystalline scraper 701 drives the baffle 702 to move downward on the surface of the cathode grid 602, the decrystalline 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 hits the baffle 702, it will be blocked by the mesh-shaped rough surface of the baffle 702 and move downward with the decrystalline scraper 701.

[0048] 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 plate 806 to rotate. Since the driving plate 806 is eccentrically arranged, when the driving plate 806 rotates, it drives one of the guide blocks 803 to move along the direction of the fixed cross 802 and stretches the reset spring 804. Since there are two driving plates 806 and the curvature of the two driving plates 806 is 90 degrees, when the driving plate 806 no longer drives the guide block 803 to move under the action of the reset stretching of the reset spring 804, the guide block 803 moves in the opposite direction under the reset stretching action of the reset spring 804, thereby causing the guide block 803 to move in the opposite direction. The cleaning brush holder 801 is driven to move back and forth on the fixed cross 802. When the crystal removal scraper 701 drives the baffle 702 to gradually approach the cleaning brush holder 801, the guide block 803 drives the cleaning brush holder 801 to move back and forth, which causes the brush on the cleaning brush holder 801 to sweep away the crystals attached to the baffle 702, thereby preventing the baffle 702 from carrying the crystals and being carried away by the water flow when moving upward, thereby improving the crystal sedimentation efficiency of the crystals in the sewage. Since the interior of the sedimentation tube 402 is in a slow flow area and the water flow is slow, the crystals swept away by the cleaning brush holder 801 will slowly settle to the bottom of the sedimentation tube 402 and be finally squeezed out as the spiral conveying blade 710 rotates, thereby achieving the purpose of automatically scraping off the crystals;

[0049] When the inclination angle of the deposition tube 402, the anode frame 601 and the cathode grid 602 needs to be adjusted according to the flow rate or flow rate, the worm 503 is driven to rotate by the servo motor, and the worm 503 drives the worm wheel 502 to rotate, and then the worm wheel 502 drives the rotating disk 401 to rotate on the inner wall of the connecting cover 3 through the driving 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 setting the sealing bellows 405, no leakage occurs when the deposition tube 402 rotates relative to the connecting cover 3.
