Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrochemical descaling technology, specifically to a lifting-type dynamic scale scraping electrochemical device. Background Technology
[0002] Electrochemical circulating water treatment technology is a new type of water treatment technology developed since the 1970s. This technology consumes only a certain amount of electricity during use and is a clean and pollution-free water treatment process. It has excellent functions of scale prevention and removal, sterilization and algae removal, and corrosion inhibition. In the electrochemical treatment of circulating cooling water systems, scale-forming ions in the circulating water are precipitated in solid form through electrolysis, reducing the hardness and alkalinity of the circulating water and ensuring the normal and stable operation of the system.
[0003] Existing automated electrochemical scraping equipment is structurally complex and prone to mechanical failures, which is detrimental to the long-term stable operation of the electrochemical device. Due to design limitations in the mechanical scraping structure, the distance between the cathode and anode plates is relatively large, and it is impossible to further reduce the distance between the anode and cathode plates. The effectiveness of electrochemical removal of calcium and magnesium ions is closely related to the distance between the electrodes. On the one hand, a large distance between the anode and cathode plates increases the resistance to ion transport and weakens the driving force of electroadsorption—the electrostatic force—severely affecting the removal efficiency of calcium and magnesium ions. On the other hand, a large distance between the electrodes requires a larger DC power supply voltage to maintain the same electrode current density, resulting in higher power requirements and significantly increased operating costs.

This utility model, through the coordinated design of the power mechanism and the scraping mechanism, employs a dynamic lifting scraping device to reduce the distance between the anode and cathode plates to the most suitable distance, greatly improving the adsorption efficiency of the equipment's reaction tank. It can simultaneously and quickly remove scale from the cathode plate of the equipment's reaction tank, preventing the scale adsorbed between the cathode and anode plates from becoming increasingly thick and causing short circuits between them. It also reduces the number of scraping operations per motor in a single reaction tank, resulting in lower energy consumption, fewer mechanical failures, more stable daily operation, and better adsorption effect. This benefits enterprises by saving water and energy.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0031] This utility model provides a lifting-type dynamic scraping electrochemical device, including a reaction tank 1. Both ends of the reaction tank 1 are equipped with lifting mechanisms 2 for raising the height. The outer side of the reaction tank 1 is connected to a liquid inlet / outlet mechanism 5 for liquid inlet / outlet and scale removal. The lifting mechanism 2 has a power mechanism 3 inside for adjusting the height. The moving end of the power mechanism 3 is equipped with a scraping mechanism 4 for contact scraping of dirt. The power mechanism 3 includes an output component and a limiting component. The output component is located inside the lifting mechanism 2, and the limiting component is located inside the reaction tank 1. The output component and the limiting component allow adjustment of the required height position for scraping.
[0032] The scraping mechanism 4 includes a support component, a locking component, a moving component, and an adapter component. The support component is located inside the reaction tank 1, the locking component is located on top of the support component, the moving component is located on top of the support component, and the adapter component is located on top of the support component. Through the cooperation of the support component, locking component, moving component, and adapter component, dirt is scraped off directly upon release. The position of the scraper can then be adjusted to adapt to the anode and cathode plates.
[0033] Preferably, the lifting mechanism 2 includes a pushing component and a covering component, with the pushing component disposed at both ends of the reaction tank 1 and the covering component disposed at the top of the pushing component.
[0034] like Figure 4As shown, the pushing assembly includes a first connecting plate 21, which is fixedly installed at the bottom of both ends of the reaction tank 1. An electric push rod 22 is fixedly installed on the top of the first connecting plate 21, and a pushing block 23 is fixedly installed at the output end of the electric push rod 22. This enables the direct upward pushing to release the cover and seal, and also drives the lower components to move upward together, thereby enabling disassembly, replacement, and placement of the anode and cathode plates.
[0035] like Figure 4 As shown, the cover assembly includes a second connecting plate 24. The bottom of the second connecting plate 24 is provided with an adapter groove 25. The second connecting plate 24 covers the outside of the push block 23 through the adapter groove 25. A top cover 26 is fixedly installed on the inner side of the second connecting plate 24, which can realize the function of covering and sealing, and can also support the components connected to it.
[0036] When it is necessary to pick up or put down the scraper, or when the scraper needs to be replaced, the electric push rod 22 is used to operate directly. The electric push rod 22 pushes the second connecting plate 24 to move the top cover 26 upward together until the top cover 26 is separated from the reaction tank 1. The top cover 26 will then drive the power mechanism 3 and the scraping mechanism 4 to move upward together until the scraping mechanism 4 is above the reaction tank 1.
[0037] Since the top cover 26 is bolted to the push block 23 through the second connecting plate 24 and the opening adapter slot 25, it can move up and down stably during the pushing and pulling process. After pushing up, the bolt fixing can be released so that the top cover 26, along with the power mechanism 3 and the scraping mechanism 4, can be removed together by external equipment to facilitate better maintenance or replacement. Replacing the scraper alone does not require complete removal.
[0038] After replacing the anode and cathode plates and the scraper, the electric push rod 22 can then pull the top cover 26 to drive the power mechanism 3 and the scraping mechanism 4 downwards until they are in the initial position, which is the position shown in the figure.
[0039] further:
[0040] like Figure 5 As shown, the output component includes a horizontal plate 31, which is fixedly installed on the inner side wall of the top cover 26. A motor 32 is fixedly installed on the top of the horizontal plate 31. The output shaft of the motor 32 is keyed to a threaded post 33. A threaded sleeve 35 is threadedly connected to the outer side of the threaded post 33. The threaded sleeve 35 is rotatably connected to the horizontal plate 31 through it.
[0041] It enables power output operation, and in conjunction with the limit component, it can move up and down, and can rise and fall stably, thereby performing scraping work.
[0042] like Figure 5As shown, the limiting component includes a vertical rod 34, which is fixedly installed at both ends of the top of the inner cavity of the top cover 26. A sliding sleeve 36 is slidably connected to the outer side of the vertical rod 34. This facilitates limiting the output component during operation, thereby preventing the phenomenon of it being unable to move up or down.
[0043] When moving up and down:
[0044] The motor 32 operates directly, driving the threaded column 33 to rotate clockwise. This, through the threaded connection, causes the threaded sleeve 35 to move upward. As the threaded sleeve 35 moves upward, it drives the scraping mechanism 4 to move up and down together. In addition, it also drives the sliding sleeve 36 to move up and down together, and the sliding sleeve 36 slides on the surface of the vertical rod 34. When it rises to the required height, the motor 32 reverses, that is, it rotates counterclockwise. Then, it descends in the opposite direction according to the above-mentioned upward movement until it returns to the initial position. The repeated upward and downward movement directly drives the scraping mechanism 4 to perform scraping operations on the cathode plate.
[0045] like Figure 6 As shown, the support assembly includes a fixed plate 42, with mounting plates 41 fixedly installed at both ends of the fixed plate 42. One end of the mounting plate 41 is fixedly installed at the end of the sliding sleeve 36 and the threaded sleeve 35, and a bracket 46 is fixedly installed on the top of the fixed plate 42. This facilitates the transmission and support functions, ensuring the connection and adjustment of the scraper below.
[0046] The adapter component includes a first adapter hole 43 and a second adapter hole 47. The first adapter hole 43 is opened on the top of the fixing plate 42, and the second adapter hole 47 is opened on the top of the bracket 46, which facilitates the limit adjustment when adjusting the scraper and is not obstructed during the adjustment process.
[0047] like Figure 6 As shown, the locking assembly includes a threaded rod 48, which slides inside the second adapter hole 47. A nut 49 is threadedly connected to the outer side of the threaded rod 48, and a connecting strip 45 is fixedly installed at the bottom end of the threaded rod 48. This serves to lock the scraper after adjustment, preventing loosening that could reduce the scraping effect.
[0048] like Figure 6 As shown, the movable component includes a connecting rod 44, which is fixedly installed at both ends of the bottom of the connecting strip 45. A mounting bracket 410 is fixedly installed at the bottom end of the connecting rod 44. A scraper body 411 is bolted inside the mounting bracket 410, which can support and install the scraper and move together with it through the above operation. The bolted connection between the two facilitates subsequent disassembly and replacement.
[0049] Based on the above, when the scraper body 411 needs to be replaced when it is located at the top of the reaction tank 1, the bolts between the scraper body 411 and the mounting bracket 410 can be directly released and then it can be removed directly. After replacing the new scraper body 411, the scraper body 411 and the mounting bracket 410 can be fixed together with bolts.
[0050] When the scraper needs to be adjusted, first loosen the nut 49, and then move the threaded rod 48 by pushing and pulling the nut 49. At this time, the threaded rod 48 will not only slide inside the second adapter hole 47, but will also move the bottom connecting strip 45 together. When the connecting strip 45 moves, it will move the mounting bracket 410 and the scraper body 411 inside through the connecting rod 44 until it moves to the required position.
[0051] Once the position has been adjusted, stop moving the device and then tighten the nut 49 so that it presses against the top of the bracket 46, thus securing it and ensuring the stability of subsequent scraping.
[0052] The length of the first adapter hole 43 and the second adapter hole 47 is not only the length shown in the figure, but can also be longer. At the same time, the width of the fixing plate 42 can be set to be smaller, so as to better adapt to the spacing between the anode and cathode plates.
[0053] at last:
[0054] like Figure 3 As shown, the liquid inlet and outlet mechanism 5 includes a water inlet pipe 51, which connects the two ends of the surface and the bottom of the back side of the reaction tank 1. A water outlet pipe 54 is connected to the top of the back side of the reaction tank 1. A drain pipe 53 is connected to the inner side wall of the bottom of the reaction tank 1. A scale discharge pipe 52 is connected to the bottom of the reaction tank 1.
[0055] The inlet pipe 51 enables water intake, the outlet pipe 54 enables water discharge from the reaction tank, the drain pipe 53 discharges liquid, and the scale removal pipe 52 removes scale as needed to prevent excessive scale buildup inside the reaction tank 1.
[0056] When scraping scale, first place the cathode and anode plates in the reaction tank 1, then adjust the position of the scraper in the scraping mechanism 4 so that it is in a position that can be scraped. Start the power mechanism 3 to drive the scraping mechanism 4 to move up and down repeatedly, so as to scrape scale from the cathode plate and remove it in the following manner.
[0057] During operation, circulating water enters reaction tank 1 for electrolysis, and an oxidation reaction occurs in the anode area to generate ClO. -Strong oxidizing substances such as H2O2 and O3 play a good role in sterilization, algae removal, and COD removal. A large number of hydroxide ions are generated in the cathode area, which react with bicarbonate ions in the water to form carbonate ions, thus disrupting the hydrolysis equilibrium of bicarbonate ions and removing the alkalinity of the water. Under the action of the electric field, calcium and magnesium ions move towards the cathode plate and react with hydroxide ions and carbonate ions to produce magnesium hydroxide and calcium carbonate precipitates. These precipitates are adsorbed on the cathode plate. The cathode plate scraping program is started by an electrical signal or time. Before starting the cathode plate scraping program, the valves on the inlet pipe 51 and outlet pipe 54 are closed, and the drain valve and drain pump are opened to drain water. After the drainage is completed, the scraping program is started, and the up-and-down scraping mechanism is activated. The scraping mechanism 4 moves back and forth up and down in the above way, which is the power mechanism 3 driving the scraping mechanism 4 to form the scraping operation. After the scraping is completed, the scale discharge valve is opened, and the solid scale is discharged to the designated location through the scale discharge pipe 52.
[0058] In summary, this utility model adopts a dynamic lifting and lowering scraping method, which can reduce the distance between the anode and cathode plates to the most suitable distance, greatly improving the adsorption efficiency of the reaction tank 1 of the equipment. Not only can it stay at a position higher than the top of the reaction tank 1 when the scraper is not scraping, but it can also avoid the scraper from being in long-term contact with water and thus rusting. At the same time, it is easy to replace and maintain. In addition, after the scraping is completed, the scale adhering to the scraper can be cleaned in time to avoid affecting the scraping effect of the next scraping and accelerating the corrosion of the scraper, thus affecting the use of the equipment.
[0059] The dynamic lifting and scraping mechanism can simultaneously and quickly remove scale from the cathode plate in reaction tank 1, preventing the scale adsorbed between the cathode and anode plates from becoming increasingly thick and causing short circuits. This reduces the number of scale scraping operations per power unit in each reaction tank 1, resulting in lower energy consumption, fewer mechanical failures, and more stable daily operation. Consequently, the adsorption effect is better, which is beneficial for enterprises to save water and energy, in line with industrial policies. At the same time, the overall structure of the equipment is simple, easy to maintain, and has a long service life.
