Description

Technical Field

[0001] This utility model relates to the technical field of circulating cooling water treatment devices, specifically an electrochemical circulating cooling water treatment device. Background Technology

[0002] Electrochemical circulating cooling water refers to water in a circulating cooling water system treated using electrochemical technology. This technology involves installing electrochemical treatment equipment in the circulating water loop, using an electric field to intervene in ions and microorganisms in the water to achieve water quality control. It is a green and efficient industrial water treatment method. Traditional circulating cooling water systems rely on chemical agents for treatment, which can easily lead to problems such as agent residues, sewage pollution, and microbial resistance. Electrochemical treatment equipment, on the other hand, achieves multifunctional water quality control through physical-electrochemical interactions.

[0003] In order to ensure the normal operation of existing electrochemical circulating cooling water treatment equipment during long-term use, the equipment door needs to be opened periodically and the operator needs to use a scraper or other auxiliary tools to clean the scale attached to the outside of the electrode plates in order to maintain the reaction efficiency of the electrode plates.

[0004] Existing electrochemical circulating cooling water treatment equipment relies on manual scraping of scale off electrode plates using auxiliary tools. However, due to the difficulty in controlling the force applied, this method can easily cause varying degrees of damage to the electrode plates, resulting in low cleaning efficiency and increased labor intensity. Therefore, we propose an electrochemical circulating cooling water treatment device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electrochemical circulating cooling water treatment device with a high degree of automation, which significantly improves the operating efficiency of the circulating cooling water treatment device, extends the service life of the electrode plates, and reduces labor costs and operational risks, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrochemical circulating cooling water treatment device, comprising a housing, wherein electrode plates are respectively provided inside the housing, and a cleaning mechanism is also included;

[0007] The cleaning mechanism includes guide grooves, scrapers, guide rods, support plates, and connecting rods. Guide grooves are respectively provided on the upper and lower inner walls of the housing. Scrapers are slidably connected between two vertically adjacent guide grooves. Each scraper is installed in conjunction with an adjacent electrode plate. Guide rods are respectively provided between the upper and lower inner walls of the housing. Symmetrically distributed support plates are slidably connected between two guide rods. Connecting rods are rotatably connected to the middle of each support plate. The ends of two vertically adjacent connecting rods near the center of the housing are rotatably connected to the rear end of the adjacent scraper. This mechanism has a high degree of automation, significantly improves the operating efficiency of the circulating cooling water treatment equipment, extends the service life of the electrode plates, and reduces labor costs and operational risks.

[0008] Furthermore, a microcontroller is provided on the left side of the housing. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the electrode plates are all electrically connected to the output terminals of the microcontroller, providing electrical connections for various electrical appliances.

[0009] Furthermore, the cleaning mechanism also includes a bidirectional lead screw and a bellows. The bidirectional lead screw is rotatably connected between the upper and lower inner walls of the housing. The middle part of the support plate is threadedly connected to the bidirectional lead screw. Bellows are provided between the two support plates, between the upper support plate and the top wall of the housing, and between the lower support plate and the bottom wall of the housing. The bidirectional lead screw is located inside the bellows to prevent impurities from affecting the precision transmission of the bidirectional lead screw.

[0010] Furthermore, the cleaning mechanism also includes a motor, which is located at the top of the housing. The bottom end of the motor's output shaft is fixedly connected to the top end of the bidirectional lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide cleaning drive.

[0011] Furthermore, a water inlet pipe is provided at the top inlet of the tank, and a water outlet pipe is provided at the left outlet of the tank. The ends of the water inlet pipe and the water outlet pipe away from the center of the tank are respectively fixedly connected to flanges to facilitate the handling of water entering and leaving the tank.

[0012] Furthermore, the lower surface of the box is provided with four legs at the four corners, and a connecting plate is provided between two longitudinally adjacent legs. The front and rear ends of the connecting plate are provided with mounting holes to provide stable support.

[0013] Furthermore, the front side of the box is connected to a door via a hinge, and a rubber sealing strip is provided on the rear side of the door. The rubber sealing strip is located between the rear side of the door and the front side of the box, which facilitates the discharge of impurities after internal cleaning.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This electrochemical circulating cooling water treatment equipment has the following advantages:

[0015] The motor drives the bidirectional lead screw to rotate. Because the threads at both ends of the bidirectional lead screw are opposite, the two support plates connected to it will move in opposite directions along the guide rod. When the support plates move, they push the scraper to slide in the guide groove through the connecting rod. Therefore, the reverse movement of the support plates will cause the scraper to make reciprocating linear motion along the surface of the electrode plate, thereby scraping off the precipitated particles and biological slime attached to the surface of the electrode plate, realizing automatic cleaning of the electrode plate. It eliminates the need for operators to manually clean the electrode plates one by one with a scraper or other tools, greatly reducing the labor intensity of operators. The pressure of the scraper on the electrode plate can be precisely controlled to avoid scratching the coating or deforming the electrode, and maintain the stability of the electrochemical performance of the electrode plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: an electrochemical circulating cooling water treatment device, including a housing 1, with electrode plates 2 (anode and cathode plates respectively) inside the housing 1. The metal anode plate undergoes an oxidation reaction, releasing metal ions. These ions combine with carbonate and phosphate ions in the water to form insoluble hydroxides or phosphates, which preferentially precipitate out compared to scale, thereby inhibiting scale deposition on the heat exchange surface. Dissolved oxygen or water molecules in the water undergo a reduction reaction at the cathode, generating hydroxide ions, which raises the local pH and promotes the migration of calcium and magnesium ions to the electrode surface, forming loose calcium / magnesium hydroxide precipitates. The device also includes a cleaning mechanism 6. A microcontroller 7 is located on the left side. The input terminal of the microcontroller 7 is electrically connected to an external power supply. The input terminals of the electrode plates 2 are all electrically connected to the output terminals of the microcontroller 7. A water inlet pipe 3 is located at the top inlet of the housing 1, and a water outlet pipe 4 is located at the left outlet of the housing 1. Flanges 5 are fixedly connected to the ends of the water inlet pipe 3 and the water outlet pipe 4 away from the center of the housing 1. Support legs 8 are located at the four corners of the lower surface of the housing 1. A connecting plate 9 is located between two longitudinally adjacent support legs 8. Mounting holes are opened at the front and rear ends of the connecting plate 9. A door 10 is rotatably connected to the front side of the housing 1 via a hinge (a locking block is located on the right side of the door 10, and a locking block is located on the right side of the housing 1). The enclosure has a mounting base, with a screw rod rotatably connected to the center of the mounting base via a pin. A dial wheel is rotatably connected to the outside of each screw rod. A clearance groove corresponding to the screw rod is provided in the center of the locking block. When locking the door, rotate the door 10 to position the locking block directly in front of the mounting base, then rotate the screw rod to position it inside the clearance groove of the locking block, and then rotate the dial wheel to press its rear side against the locking block, thus fixing the door 10. A rubber sealing strip is provided on the rear side of the door 10, located between the rear side of the door 10 and the front side of the enclosure 1. In circulating water treatment, when electrochemical circulating cooling water treatment equipment is required, it is first connected via a connecting plate... 9. The mounting holes are opened to fix the box 1 to the designated position. Then, the flange 5 at the top of the water inlet pipe 3 is fixedly connected to the external water supply pipe, and the flange 5 of the water outlet pipe 4 is fixedly connected to the external water supply pipe. The cooling circulating water enters the box 1 through the top water inlet pipe 3. At this time, the electrode plate 2 is energized under the control of the microcontroller 7. The calcium and magnesium ions, microorganisms, organic matter and other substances in the water are treated through electrochemical action (such as electrolysis and oxidation-reduction reaction). After treatment, the circulating cooling water will be discharged from the box 1 through the water outlet pipe 4 and enter the next process. After closing the box door 1, the electrochemical circulating cooling water treatment equipment will work normally to treat the circulating cooling water.

[0024] Cleaning mechanism 6 includes guide grooves 61, scrapers 62, guide rods 63, support plates 64, and connecting rods 65. Guide grooves 61 are respectively provided on the upper and lower inner walls of the housing 1. Scrapers 62 are slidably connected between two vertically adjacent guide grooves 61. Each scraper 62 is installed in conjunction with an adjacent motor plate 2. Guide rods 63 are respectively provided between the upper and lower inner walls of the housing 1. Symmetrically distributed support plates 64 are slidably connected between two guide rods 63. Connecting rods 65 are rotatably connected to the middle of each support plate 64. The ends of two vertically adjacent connecting rods 65 closest to the center of the housing 1 are rotatably connected to the rear end of the adjacent scraper 62. Cleaning mechanism 6 It also includes a bidirectional lead screw 66 and a bellows 67. The bidirectional lead screw 66 is rotatably connected between the upper and lower inner walls of the housing 1. The middle part of the support plate 64 is threadedly connected to the bidirectional lead screw 66. Bellows 67 are respectively provided between the two support plates 64, between the upper support plate 64 and the top wall of the housing 1, and between the lower support plate 64 and the bottom wall of the housing 1. The bidirectional lead screw 66 is located inside the bellows 67. The cleaning mechanism 6 also includes a motor 68, which is located at the top of the housing 1. The bottom end of the output shaft of the motor 68 is fixedly connected to the top end of the bidirectional lead screw 66. The input end of the motor 68 is electrically connected to the output end of the microcontroller 7. When When the electrode plate 2 inside the housing 1 is used for a long time and the scale buildup on the outside affects its water treatment efficiency, first disconnect the water inlet pipe 3 and drain the remaining cooling water from the water outlet pipe 4. Then, rotate the dial on the left side of the housing 1 to release the dial from the limit on the housing door 1 and open the front hinged housing door 10. Under the control of the microcontroller 7, the motor 68 starts to run, and the output shaft drives the bidirectional lead screw 66 to start rotating. Since the threads at both ends of the bidirectional lead screw 66 are in opposite directions, the two support plates 64 connected to it will move in opposite directions along the guide rod 63 (one moves up and the other moves down). When the support plates 64 move, they are connected by the connecting rod 65. The scraper 62 is pushed to slide in the guide groove 61. Since the vertically adjacent scrapers 62 are rotatably connected to the support plate 64 through the connecting rod 65, the reverse movement of the support plate 64 will cause the scraper 62 to reciprocate linearly along the surface of the electrode plate 2. The corrugated pipe 67 between the support plate 64 and the top and bottom walls of the tank 1 extends and retracts with the movement of the support plate 64, preventing impurities in the water from entering the transmission area of ​​the bidirectional screw 66, avoiding mechanical jamming, and protecting the internal structure from corrosion. It scrapes off the sediment particles and biological slime attached to the surface of the electrode plate. The scraped-off scale will fall to the bottom wall of the tank 1 under the action of gravity, and then be removed with the help of other tools.

[0025] The working principle of the electrochemical circulating cooling water treatment equipment provided by this utility model is as follows: When the electrochemical circulating cooling water treatment equipment is needed for circulating water treatment, firstly, the housing 1 is fixed to the designated position through the mounting holes opened in the connecting plate 9. Then, the flange 5 at the top of the inlet pipe 3 is fixedly connected to the external water supply pipe, and the flange 5 of the outlet pipe 4 is fixedly connected to the external water supply pipe. The cooling circulating water enters the housing 1 through the top inlet pipe 3. At this time, the electrode plate 2 is energized under the control of the single-chip microcomputer 7, and the cooling water is energized through the electrical circuit. Chemical processes (such as electrolysis and redox reactions) treat calcium and magnesium ions, microorganisms, and organic matter in the water. The treated circulating cooling water is then discharged from the interior of tank 1 through outlet pipe 4 and enters the next process. When the electrode plates 2 inside tank 1 have been used for a long time and the scale buildup on the outside affects their water treatment efficiency, first disconnect the inlet pipe 3 to discharge the remaining cooling water from the outlet pipe 4. Then, rotate the dial on the left side of tank 1 to release the dial from its restriction on the tank door 1, opening the front hinged door 10 to allow water to pass through. Under the control of the microcontroller 7, the motor 68 starts to run, and the output shaft drives the bidirectional lead screw 66 to rotate. Since the threads at both ends of the bidirectional lead screw 66 are in opposite directions, the two support plates 64 threaded to it will move in opposite directions along the guide rod 63 (one moves up and the other moves down). When the support plates 64 move, they push the scraper 62 to slide in the guide groove 61 through the connecting rod 65. Since the vertically adjacent scrapers 62 are rotatably connected to the support plates 64 through the connecting rod 65, the reverse movement of the support plates 64 will cause the scrapers 62 to slide along the surface of the electrode plate 2. The surface makes reciprocating linear motion. The corrugated pipe 67 between the support plate 64 and the top and bottom walls of the tank 1 extends and retracts with the movement of the support plate 64, preventing impurities in the water from entering the transmission area of ​​the bidirectional screw 66, avoiding mechanical jamming, and protecting the internal structure from corrosion. It scrapes off the sediment particles and biological slime attached to the surface of the electrode plate. The scraped-off scale will fall to the bottom wall of the tank 1 under the action of gravity, and then be removed with the help of other tools. After closing the tank door 1, the electrochemical circulating cooling water treatment equipment will work normally to treat the circulating cooling water.

[0026] It is worth noting that the microcontroller 7 disclosed in the above embodiments can be a PIC18F4550, the motor 68 can be a YS8024, and the microcontroller 7 controls the operation of the motor 68 and the electrode plate 2 using methods commonly used in the prior art.
