Technical Field

[0001] This application relates to the field of water treatment, and in particular to a high-efficiency electrochemical circulating water treatment device. Background Technology

Electrochemical methods can continuously generate active substances in situ through electrochemical reactions, achieving controlled precipitation of hardness ions such as calcium and magnesium and removal of microorganisms in circulating water without secondary pollution, making it a promising circulating water treatment technology. This utility model relates to the field of electrochemical water treatment for circulating cooling water, specifically a novel electrochemical water treatment device. Water conservation and wastewater recycling are requirements of the sustainable development strategy. Industrial cooling water accounts for more than 80% of industrial water consumption; recycling cooling water has significant environmental, economic, and social benefits.

[0003] Utility model patent CN214243886U discloses a power-adjustable electrochemical circulating water treatment device, including a tank and a power supply. Water inlet pipes are fixedly connected to the front and rear sides of the left side of the tank, and drain pipes are fixedly connected to the front and rear sides of the right side of the tank. An exhaust port is opened on the top of the tank. Water distribution chambers are fixedly connected to both the left and right sides of the tank, and each water distribution chamber is connected to the water inlet and drain pipes. Clamping devices are provided on both the left and right sides of the tank from front to back, and a cathode plate is provided between two of the clamping devices. The positive and negative terminals of the power supply are both connected to a first wire.

[0004] In one of the aforementioned power-adjustable electrochemical circulating water treatment devices, scale adsorbed on the cathode plate after water treatment requires the cathode plate to be disassembled for cleaning, resulting in reduced work efficiency. Utility Model Content

[0005] To address the aforementioned problems, this application provides a high-efficiency electrochemical circulating water treatment device.

[0006] The high-efficiency electrochemical circulating water treatment equipment provided in this application adopts the following technical solution:

[0007] A high-efficiency electrochemical circulating water treatment device includes a tank containing multiple cathode plates and anode plates arranged alternately within the tank. The tank is equipped with a scraping assembly for removing scale from the cathode plates and an mounting assembly for installing cathode plates of different thicknesses. The scraping assembly includes mounting plates respectively disposed on both sides of the cathode plates. Each mounting plate has a scraper on its opposite sidewall. Multiple equidistant springs are fixedly connected between the scrapers and the mounting plates. An electric telescopic rod is fixedly connected to one sidewall of the tank. A connecting plate is fixedly connected to the output end of the electric telescopic rod. Multiple connecting rods are fixedly connected to the lower surface of the connecting plate, with the ends of the connecting rods away from the connecting plate fixedly connected to the mounting plates.

[0008] By adopting the above technical solution, during use, the cathode plate is installed into the housing using the mounting assembly, positioning the cathode plate between two scrapers. Spring extension pushes the scrapers closer together, causing them to abut against both sides of the cathode plate. When scale needs to be cleaned from the cathode plate, the electric telescopic rod is activated, raising and lowering the connecting plate. This, in turn, moves the mounting plate, allowing the scrapers to move along the sidewalls of the cathode plate and remove the scale. This minimizes the need to disassemble the cathode plate for cleaning, thus reducing work efficiency.

[0009] Preferably, the mounting assembly includes mounting grooves formed on both side walls inside the housing and located between two mounting plates respectively. Mounting blocks adapted to the mounting grooves are fixedly connected to both side walls of the cathode plate. T-shaped clamping blocks are provided at the top of the housing above the mounting grooves. The bottom end of the T-shaped clamping block is slidably disposed in the mounting groove and abuts against the mounting block. Two fastening bolts are provided on the upper surface of the T-shaped clamping block. The threaded ends of the fastening bolts pass through the T-shaped clamping block and are threadedly connected to the housing.

[0010] By adopting the above technical solution, the T-shaped clamping block can be disassembled by rotating the fastening bolts, and then the cathode plate can be pulled to make the mounting block slide in the mounting groove to remove the cathode plate. This makes it convenient to replace cathode plates of different thicknesses according to changes in water quality, and adjust the distance between the cathode plate and the anode plate in the tank to improve the water treatment effect.

[0011] Preferably, each spring is provided with a limiting rod, one end of which is fixedly connected to the scraper, and the other end of which passes through the mounting plate and forms a sliding arrangement.

[0012] By adopting the above technical solution, the stability of the spring can be improved by using the limiting rod, preventing the scraper from hitting the cathode plate and bending the spring when scraping the cathode plate, which would cause the scraper to swing.

[0013] Preferably, a plurality of semi-permeable membranes are installed inside the housing, and the semi-permeable membranes are respectively located between the cathode plate and the anode plate.

[0014] By adopting the above technical solution, the semi-permeable membrane allows only certain ions and small molecules to pass freely, which has a significant effect on enriching chloride ions and can significantly improve the dechlorination efficiency.

[0015] Preferably, the side walls of the tank are provided with multiple water supply pipes for conveying circulating water, and the tank is provided with connecting pipes on both sides. The end of each water supply pipe away from the tank is fixedly connected to the connecting pipe.

[0016] By adopting the above technical solution, circulating water can be conveniently transported into the tank for treatment via connecting pipes and water supply pipes, and then discharged, thereby improving the purification efficiency of circulating water.

[0017] Preferably, each of the mounting slots is fixedly connected to a fixing rod, and the mounting blocks are respectively sleeved on the fixing rods and form a sliding arrangement.

[0018] By adopting the above technical solution, when the mounting block is slid into the mounting groove, the mounting block is fitted onto the fixing rod, which can improve the stability of the mounting block in the mounting groove and prevent the cathode plate from shaking.

[0019] Preferably, the maximum distance between the connecting plate and the housing is greater than the height of the cathode plate.

[0020] By adopting the above technical solution, it is possible to prevent the top of the cathode plate from coming into contact with the connecting plate when the cathode plate is removed from the box, thus preventing the cathode plate from being difficult to remove.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the cooperative arrangement of structures such as mounting plates, scrapers, and springs. During use, the cathode plate is installed into the housing via the mounting assembly, positioning it between two scrapers. The springs extend and retract, pushing the scrapers closer together so that they abut against both sides of the cathode plate. When it is necessary to clean the scale on the cathode plate, the electric telescopic rod is activated, causing the connecting plate to rise and fall. The connecting rod then moves the mounting plate up and down, allowing the scrapers to move along the side wall of the cathode plate and scrape off the scale. This minimizes the need to disassemble the cathode plate for cleaning, thus reducing work efficiency.

[0023] 2. Remove the T-shaped clamping block by rotating the fastening bolts, then pull the cathode plate to slide the mounting block in the mounting groove and remove the cathode plate. This allows for easy replacement of cathode plates of different thicknesses according to changes in water quality, and adjustment of the distance between the cathode plate and anode plate in the tank, thereby improving the water treatment effect.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a high-efficiency electrochemical circulating water treatment device.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A high-efficiency electrochemical circulating water treatment device includes a tank 1, which contains multiple cathode plates 2 and anode plates 3. The cathode plates 2 and anode plates 3 are arranged alternately inside the tank 1. The anode plates 3 are fixedly connected to the tank 1. The tank 1 is provided with a scraping component for scraping scale off the cathode plates 2 and an installation component for installing cathode plates 2 of different thicknesses. The scraping component includes an installation plate 4, a scraper 5, a spring 6, an electric telescopic rod 7, a connecting plate 8, and a connecting rod 9.

[0032] Multiple mounting plates 4 are provided and are respectively located on both sides of the cathode plate 2. Multiple scrapers 5 are provided and are respectively located between the mounting plates 4 and the cathode plate 2. Multiple springs 6 are provided and are respectively located between the scrapers 5 and the mounting plates 4 and are equidistantly arranged. An electric telescopic rod 7 is fixedly connected to one side wall of the housing 1. One end of the lower surface of the connecting plate 8 is fixedly connected to the output end of the electric telescopic rod 7 and the connecting plate 8 is located above the housing 1. Multiple connecting rods 9 are provided and are all fixedly connected to the lower surface of the connecting plate 8. The end of the connecting rod 9 away from the connecting plate 8 is fixedly connected to the mounting plate 4.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The installation assembly includes mounting grooves 10 located on both sides of the inner sidewall of the housing 1 and between two mounting plates 4. Mounting blocks 11, which are adapted to the mounting grooves 10, are fixedly connected to both sides of the cathode plate 2. T-shaped clamping blocks 12 are provided at the top of the housing 1 above the mounting grooves 10. The bottom end of the T-shaped clamping block 12 is slidably disposed in the mounting groove 10 and abuts against the mounting block 11. Two fastening bolts 13 are provided on the upper surface of the T-shaped clamping block 12. The screw ends of the fastening bolts 13 pass through the T-shaped clamping block 12 and are threadedly connected to the housing 1. The T-shaped clamping block 12 can be removed by rotating the fastening bolts 13. Then, the cathode plate 2 is pulled to make the mounting block 11 slide in the mounting groove 10 and the cathode plate 2 can be removed. This allows for the replacement of cathode plates 2 of different thicknesses according to changes in water quality, and adjustment of the distance between the cathode plate 2 and the anode plate 3 in the housing 1, thereby improving the water treatment effect.

[0034] Reference Figure 1 and Figure 2 Each spring 6 is equipped with a limiting rod 14. One end of the limiting rod 14 is fixedly connected to the scraper 5, and the other end of the limiting rod 14 passes through the mounting plate 4 and forms a sliding setting. The limiting rod 14 can improve the stability of the spring 6 and prevent the scraper 5 from abutting against the cathode plate 2. When scraping the cathode plate 2, the spring 6 will bend, causing the scraper 5 to swing.

[0035] Reference Figure 1 and Figure 3 Multiple semi-permeable membranes 15 are installed inside the housing 1. The semi-permeable membranes 15 are located between the cathode plate 2 and the anode plate 3. The semi-permeable membranes 15 include a ruthenium-titanium-iridium coating, which includes ruthenium dioxide, titanium dioxide and iridium metal. Only certain ions and small molecules are allowed to pass freely through the semi-permeable membranes 15, which has a significant effect on enriching chloride ions and can significantly improve the chloride removal efficiency.

[0036] Reference Figure 1 Multiple water supply pipes 16 for conveying circulating water are provided on both sides of the tank body 1. Connecting pipes 17 are provided on both sides of the tank body 1. The end of the water supply pipe 16 away from the tank body 1 is fixedly connected to the connecting pipe 17. The circulating water is conveniently transported into the tank body 1 for treatment through the connecting pipe 17 and the water supply pipe 16, and then discharged, thereby improving the purification efficiency of the circulating water.

[0037] Reference Figure 4 Each mounting groove 10 is fixedly connected with a fixing rod 18. The mounting blocks 11 are respectively sleeved on the fixing rods 18 and form a sliding arrangement. When the mounting blocks 11 are slid into the mounting groove 10, the mounting blocks 11 are sleeved on the fixing rods 18, which can improve the stability of the mounting blocks 11 in the mounting groove 10 and prevent the cathode plate 2 from shaking.

[0038] Reference Figure 1 The maximum distance between the connecting plate 8 and the housing 1 is greater than the height of the cathode plate 2, so as to prevent the top of the cathode plate 2 from coming into contact with the connecting plate 8 when the cathode plate 2 is taken out of the housing 1, which would make it difficult to remove the cathode plate 2.

[0039] The implementation principle of the high-efficiency electrochemical circulating water treatment equipment in this application embodiment is as follows: During use, the T-shaped clamping block 12 is removed by rotating the fastening bolt 13, and then the cathode plate 2 is pulled to make the mounting block 11 slide in the mounting groove 10 to remove the cathode plate 2. According to the water quality changes, cathode plates 2 of different thicknesses are installed in the tank 1, so that the cathode plate 2 is located between two scrapers 5. The spring 6 pushes the scrapers 5 closer to each other, so that the scrapers 5 abut against the two sides of the cathode plate 2 respectively. When it is necessary to clean the scale on the cathode plate 2, the electric telescopic rod 7 is activated to raise and lower the connecting plate 8. The connecting rod 9 drives the mounting plate 4 to raise and lower, so that the scrapers 5 move on the side wall of the cathode plate 2 to scrape off the scale. This avoids the need to remove the cathode plate 2 for cleaning, which would reduce the working efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
