Description

Technical Field

[0001] This utility model relates to the field of hardness removal technology for circulating water, and in particular to an electrochemical hardness removal device for circulating water systems. Background Technology

[0002] Before the advent of electrochemical hardening removal technology, circulating water systems commonly used chemical precipitation methods such as adding lime and soda ash, as well as ion exchange methods for hardening removal. Chemical precipitation methods produce a large amount of sludge, which is costly to treat and can easily cause secondary pollution. Ion exchange methods require regular resin regeneration, consume a large amount of acid and alkali, and also suffer from problems such as resin aging and decreased exchange capacity. These methods cannot meet the requirements of modern industry for circulating water quality and environmental protection, thus prompting the research and development of new hardening removal technologies.

[0003] The existing circulating water has a relatively low conductivity. When the electrodes are far apart, the electrolysis efficiency is very low, and it is almost impossible to effectively generate enough hydroxide ions. Therefore, it cannot effectively remove a large amount of bicarbonate ions from the water, and thus cannot effectively generate carbonate ions, but further generates calcium carbonate. The hardness removal efficiency is too low.

[0004] Existing patent (publication number: CN222099626U) discloses an electrochemical hardening removal device, comprising an electrolytic tank with an outlet and an inlet. An anode plate and a cathode plate are installed inside the electrolytic tank. The anode plate is connected to the positive terminal of a power source, and the cathode plate is connected to the negative terminal. The cathode plate includes a conductive plate and a flexible conductive component mounted on the conductive plate. A descaling component is located on one side of the flexible conductive component. The descaling component is moved by a driving component to physically disturb the flexible conductive component, thereby causing the deposits on the flexible conductive component to fall off. This invention adds a diaphragm between the anode and cathode plates to separate the cathode and anode areas. This ensures that the acid and alkali produced by the reaction between the anode and cathode plates will not neutralize after the distance between the cathode and anode plates is shortened, significantly improving the hardening removal efficiency. It also effectively isolates the mixing of hydrogen and oxygen, reducing the risk of explosion.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing electrochemical hardening devices lack a pre-treatment structure for disassembling the electrode tube body. As a result, when disassembling the electrode tube, a large amount of scale, impurities, and residual chemicals adhering to the surface of the electrode tube are directly exposed to the surrounding environment, which may cause dirt to fall and contaminate the work site, thereby increasing cleaning costs.

[0006] Therefore, an electrochemical hardening removal device for circulating water systems is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An electrochemical hardening removal device for a circulating water system includes a water storage tank 1, a pre-cleaning mechanism 2 fixedly connected to the right side of the water storage tank 1, a guiding mechanism 3 fixedly connected to the left side of the inner wall of the water storage tank 1, and an electrode tube body 4 slidably connected to the inner side of the pre-cleaning mechanism 2.

[0029] The pre-cleaning mechanism 2 includes a plug hole 21, a cleaning ring 22, a protective shell 23, a guide hole 24, and a sludge collection box 25. The plug hole 21 is located on the right side of the water tank 1. The cleaning ring 22 is fixedly connected to the right side of the inner wall of the water tank 1. The protective shell 23 is fixedly connected to the right side of the inner wall of the water tank 1. The guide hole 24 is located on both sides of the protective shell 23. The sludge collection box 25 is slidably connected to the bottom of the inner side of the guide hole 24. The right side of the sludge collection box 25 extends through the water tank 1 to the outside of the water tank 1.

[0030] In this embodiment: the water storage tank 1 supports and limits the pre-cleaning mechanism 2, the guiding mechanism 3, the electrode tube body 4, and the circulating water. The electrode tube body 4, through an electrochemical reaction on its surface, promotes the directional migration and crystallization of calcium and magnesium ions in the circulating water, thereby reducing the hardness of the circulating water and effectively preventing scale buildup on the inner walls of pipes and equipment in the circulating water system. This ensures efficient system operation, maintains good heat exchange efficiency, and reduces energy loss due to scale buildup. The insertion hole 21 serves as a channel for inserting and removing the electrode tube body 4 from the water storage tank 1, facilitating the installation and disassembly of the electrode tube body 4. The cleaning ring 22 has a structure with a small diameter on the left and a large diameter on the right; the large diameter on the right facilitates the electrode tube body... 4. Smooth entry: During the insertion or removal of the electrode tube body 4, it plays a preliminary guiding role, reducing the difficulty of insertion. The small diameter on the left side fits tightly against the surface of the electrode tube body 4, which can scrape off the dirt attached to the surface of the electrode tube body 4. The protective shell 23 provides protection for the cleaning process, so that the dirt and impurities generated during the cleaning process fall into the inner side of the dirt storage box 25, preventing them from spreading to other areas of the water storage tank 1. It can also support and limit the dirt storage box 25 and the guide hole 24. The guide hole 24 can support and limit the electrode tube body 4. The dirt storage box 25 is used to store the contaminants cleaned from the electrode tube body 4, and it is convenient for users to pull it out from the outside of the water storage tank 1, which is convenient for operators to clean the collected contaminants regularly.

[0031] Specifically, such as Figure 4 As shown, the guiding mechanism 3 includes a locking rod 31, a limiting rod 32, a supporting rotating rod 33, a connecting plate 34, several limiting posts 35 and several guiding rotating wheels 36. The locking rod 31 is fixedly connected to the left side of the inner wall of the water storage tank 1.

[0032] Specifically, such as Figure 4 As shown, the limiting rod 32 is fixedly connected to both sides of the inner wall of the water storage tank 1, and the left side of the limiting rod 32 passes through the water storage tank 1 and is fixedly connected to the outside of the water storage tank 1.

[0033] Specifically, such as Figure 4 As shown, the support rod 33 is slidably connected to the inner side of the limiting rod 32, the connecting plate 34 is fixedly connected to the top of the right side of the support rod 33, the limiting post 35 is welded to the top of the connecting plate 34, and the guide wheel 36 is rotatably connected to the top of the surface of the limiting post 35.

[0034] In this embodiment: the snap-fit ​​rod 31 provides reliable snap-fit ​​positioning for the electrode tube body 4, ensuring the stability of the electrode tube body 4 within the water storage tank 1 and preventing lateral movement of the electrode tube body 4 during operation. The limiting rod 32 provides a sliding track for the supporting rotating rod 33. By sliding inside the limiting rod 32, the supporting rotating rod 33 can drive the connecting plate 34 to move up and down. When the connecting plate 34 moves up and down, it can drive the limiting post 35 to move up and down. The limiting post 35 can support and limit the guide wheel 36. The guide wheel 36 can fit against the surfaces on both sides of the electrode tube body 4 during installation, preventing lateral movement of the electrode tube body 4 during installation. At the same time, after the electrode tube body 4 is installed, the user can drive the connecting plate 34 downward by using the supporting rotating rod 33 to prevent the guide wheel 36 from affecting the electrochemical reaction of the electrode tube body 4 with the circulating water.

[0035] Specifically, such as Figure 4 As shown, a protective pad 5 is fitted on the surface of the guide wheel 36, and the surface of the protective pad 5 is engraved with anti-slip texture.

[0036] Specifically, such as Figure 5 As shown, a limit ring 6 is fixedly connected to the top of the left side of the support rod 33, and the surface of the limit ring 6 is engraved with anti-slip texture.

[0037] In this embodiment: by setting a protective pad 5, direct contact between the electrode tube body 4 and the guide wheel 36 can be avoided during the movement of the guide electrode tube body 4, preventing scratches and wear on the surface of the electrode tube body 4 due to friction. By setting an anti-slip texture, the friction between the electrode tube body 4 and the guide wheel 36 is increased, allowing the electrode tube body 4 to cooperate more stably with the guide wheel 36 during movement and avoiding slippage. By setting a limiting ring 6, it is convenient for the user to slide the support rod 33 and prevent the support rod 33 from sliding excessively. By setting an anti-slip texture, it is convenient for the operator to grip the support rod 33 better when adjusting or moving it, increasing the friction between the hand and the limiting ring 6.

[0038] Specifically, such as Figure 5 As shown, a reinforcing ring 7 is fixedly connected to the left side of the snap-fit ​​rod 31. The surface of the reinforcing ring 7 is coated with anti-corrosion paint. The right side of the snap-fit ​​rod 31 is snapped into the inner side of the left side of the electrode tube body 4.

[0039] Specifically, such as Figure 3 As shown, a handle 8 is fixedly connected to the right side of the sludge storage box 25, and the surface of the handle 8 is engraved with anti-slip texture.

[0040] In this embodiment: by setting the reinforcing ring 7, the overall structural strength of the clamping rod 31 is enhanced, making it less prone to deformation or damage when subjected to the clamping force of the electrode tube body 4 for a long time. By setting the anti-corrosion coating, the clamping rod 31 can be effectively resisted from the corrosion of circulating water and corrosive substances that may exist in the surrounding environment, thus extending the service life of the clamping rod 31. By setting the handle 8, an easy gripping part is provided for the operator, making it convenient to pull out the sludge storage box 25 from the guide hole 24. By setting the anti-slip texture, the friction between the hand and the handle 8 is increased, preventing the sludge storage box 25 from slipping due to sweaty hands or uneven force.

[0041] Working Principle: First, the user moves the water tank 1 to the designated working position. Then, by holding the limiting ring 6, the user slowly pushes the support rod 33 downward. At this time, the right side of the support rod 33 will rise accordingly, thereby driving the connecting plate 34 to rise synchronously. After both connecting plates 34 are raised into place, the user aligns the electrode tube body 4 with the insertion hole 21 and inserts it smoothly. The electrode tube body 4 enters the guide hole 24 along the right side of the cleaning ring 22. The guide hole 24 guides it to move to the left side inside the water tank 1. After the electrode tube body 4 has moved a certain distance, it will contact the guide wheels 36 on both sides. The guide wheels 36, with their rotational characteristics, smoothly guide the electrode tube body 4 to the position where it engages with the locking rod 31. After the electrode tube body 4 is properly installed, the user holds the limiting ring 6 again and lifts the support rod 33 upward. At this time, the right side of the support rod 33 rotates downward, causing the connecting plate 34 and the guide wheels 36 to move downward together. Then, the electrode tube body 4 moves to the left side inside the water tank 1. The user adds circulating water to the water tank 1 and powers on and starts the electrode tube body 4. The electrode tube body 4 then begins to work. After running for a period of time, if the electrode tube body 4 needs to be disassembled, maintained, and cleaned, the user first turns off the power to the electrode tube body 4. Then, the user holds the right side of the electrode tube body 4 and pulls it outward from the water tank 1. When the electrode tube body 4 contacts the left side of the cleaning ring 22, the left side of the cleaning ring 22 adheres to the surface of the electrode tube body 4, scraping away the dirt attached to the surface of the electrode tube body 4 one by one. After the dirt is removed from the surface of the electrode tube body 4, it falls directly into the dirt collection box 25 below under the action of gravity. After the user completes the disassembly and maintenance of the electrode tube body 4, the electrode tube body 4 is reinstalled into the inside of the water tank 1 according to the previous operating steps. Finally, the user holds the handle 8 and gently pulls out the dirt collection box 25 to uniformly process the dirt collected in the dirt collection box 25. The entire operation process is then successfully completed.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
