Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and in particular to a fusion-type electrochemical water treatment device. Background Art

[0002] Circulating cooling water systems use cooling equipment to lower the temperature of the heated cold water, then pump it back to the production equipment for reuse. However, during the circulation process, water quality often causes various problems, hindering the smooth operation of the system. Specifically, scale-forming ions such as Ca2+ and Mg2+ in the water are attracted by electrostatic force and gather toward the cathode area, forming precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2, which eventually deposit and form scale on the cathode surface. Therefore, regular cleaning of the cathode scale becomes necessary.

[0003] A common cathode descaling method involves adding an acid solution to the circulating water, using a chemical reaction to remove scale. However, this method corrodes the cathode, shortening its service life. Residual acid can also interfere with water treatment and corrode the pipes. Another approach involves mechanically scraping the cathode with a hanging plate. However, this requires downtime, causing wear on the cathode surface. Furthermore, due to the complex structure and the presence of holes in the cathode, complete removal of the scale is difficult. Furthermore, this method is labor-intensive and inefficient, impacting overall production efficiency. Traditional electrochemical water treatment devices are bulky, occupy a large space, and lack installation flexibility. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention provides a fused electrochemical water treatment device that does not rely on the addition of acid solution. This device simplifies and swifts cathode descaling, eliminates the need to interrupt equipment operation, and achieves high descaling efficiency. The descaling solution is integrated into the piping system, saving space and allowing for flexible and adaptable installation.

[0005] The technical solution adopted by the present invention is as follows: comprising a movable base and a processing tube, wherein a mounting plate is fixed to the base, and two rows of staggered rollers are provided on the mounting plate, wherein the wheel surface of the rollers is concave, and the processing tubes are folded back and connected to the rollers in sequence from top to bottom to form a rolling path;

[0006] An inner tube is coaxially arranged inside the processing tube, a cathode spring is coaxially arranged between the inner tube and the processing tube, an anode spring is coaxially arranged inside the inner tube, the anode spring is connected to the anode of the power supply, and the cathode spring is connected to the cathode of the power supply, and a small hole is provided on the inner tube;

[0007] The processing tube and the inner tube are both elastic, so that they can be bent to a certain extent without being damaged. Working principle and process:

[0008] The upper end of the treatment tube serves as the water inlet, and the lower end serves as the water outlet. During operation, scale-forming ions such as Ca2+ and Mg2+ in the water are attracted by electrostatic forces and attracted to the cathode spring, where they form precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2. These precipitates accumulate on the surface of the cathode spring, weakening the cathode's ionization efficiency and hindering the precipitation of scale-forming ions. This results in the waste of electrical energy but ineffective precipitate removal, hindering the purification of the circulating water. Pulling the outlet end of the treatment tube drives the roller to rotate, causing the treatment tube to slide along the concave surface of the roller. The point of contact between the treatment tube and the roller is the fold, which changes with the movement of the treatment tube. Because both the anode and cathode springs are helical, when the treatment tube enters the fold from a straight line, the spring pitch changes, causing deformation. This compresses the inner coil of the spring, tightening it, while the outer coil becomes relatively loose. However, the scale attached to the cathode spring lacks elasticity and cannot deform with the spring. Therefore, the scale layer at the fold will break and fall off and be carried to the water outlet by the water flow. This design makes cathode descaling quick and convenient, and efficient cleaning can be achieved without disassembling the equipment or shutting down the machine. In addition, the water treatment components are directly integrated into the treatment pipe, providing greater installation flexibility. The treatment pipe is arranged on the roller in the form of a wound coil and placed vertically in a flat shape. This not only saves space, but this coiled layout also cools the circulating water, reducing the amount of water evaporation and delaying the increase in salinity caused by evaporation.

[0009] Preferably, a reset mechanism is provided at the upper end of the treatment tube, comprising a reset block, two reset springs, and a fixed block, the fixed block being provided on a mounting plate and fixed to the upper end of the treatment tube, the reset block being vertically provided with two mutually parallel guide rods, the two guide rods being passed through the fixed block, the reset block and the fixed block being connected via two reset springs, the two reset springs being coaxially sleeved on the two guide rods, respectively. When the water outlet end of the treatment tube is pulled until it cannot be pulled any further, the reset spring is in a compressed state, the treatment tube is released at this time, the reset spring deforms and resets, driving the reset block to reset, and the reset block pulls the water outlet end of the treatment tube to reset the treatment tube, and repeated pulling and releasing of the treatment tube can cause the scale on the cathode spring to break and fall off as much as possible.

[0010] Preferably, the outer side of each of the folded portions of the treatment tube is provided with an arc plate, each of the arc plates being mounted on a mounting plate, each of the arc plates being coaxial with the rollers at the corresponding folded portions, a plurality of extrusion wheels being mounted on the inner side of the arc plates, the distance between the extrusion wheels and the bottom of the concave surface of the rollers being less than the diameter of the treatment tube, and a protrusion being provided on the inner wall of the treatment tube. When the treatment tube passes through the folded portion, the treatment tube is compressed by the extrusion wheels, and as the treatment tube is pulled, the extrusion wheels exert pressure on the treatment tube, causing it to deform. This deformation, in turn, causes the protrusions on the inner wall of the treatment tube to closely contact and compress the cathode spring, effectively removing the scale layer remaining on the surface of the cathode spring and enhancing the scale cleaning effect.

[0011] Preferably, a horizontal square tube is provided at the lower end of the treatment tube, the lower end of the treatment tube is connected to the square tube, and a filter is provided in the square tube. The cleaned scale is intercepted by the filter, thereby preventing it from entering the circulation system and avoiding clogging of the treatment tube due to scale.

[0012] Preferably, a scraping mechanism is provided in the square tube, comprising a scraper, a slider, and a slide rod. The scraper is provided on the slider, which is slidably connected to the slide rod, and the scraper contacts the surface of the filter. The scraper slides on the surface of the filter to scrape off the structure on the filter, thereby preventing the filter from being clogged by scale.

[0013] Preferably, an airbag is fixed to the slider. The square tube has a through-hole on its upper surface, and an elastic membrane is sealed and fixed to the inner wall of the through-hole. A lifting plate is fixed to the center of the elastic membrane, and the lifting plate has an area larger than the through-hole. A pulley is fixed to the bottom of the lifting plate. A rotating shaft is provided on the inner bottom of the square tube, and a pulley is provided on the rotating shaft. The pulley passes around the bottom of the pulley and is fixed to the bottom of the slider. When the filter screen becomes clogged due to excessive accumulation of scale, water cannot flow smoothly through the filter screen, which causes the water pressure in the pipe to gradually increase. As the water pressure increases, the elastic membrane expands upward due to the pressure. This expansion, in turn, drives the connected lifting plate upward. As the lifting plate rises, it pulls the pulley, and the other end of the pulley pulls a slider. As the pulley is pulled, the slider descends along its track. As the slider descends, a scraper mounted on it contacts and scrapes the surface of the filter screen, effectively removing any debris adhering to the filter screen. Once the debris is removed, water in the pipe can flow smoothly through the filter again, and the water pressure will return to normal. At this point, the elastic membrane, freed from external pressure, elastically resets to its original state. Simultaneously, the buoyancy provided by the airbag causes the scraper to rise upward and return to its initial position. The entire cleaning process is automatic and efficient, ensuring the continued unobstructed flow of the filter and stable operation of the system.

[0014] Preferably, a collection cylinder is located below the filter, the top of which is connected to the bottom of the square tube. A valve is installed on the collection cylinder. The removed scale is successfully intercepted by the filter and stored in the collection cylinder, effectively preventing it from entering the circulation system. When the scale in the collection cylinder needs to be cleaned, simply open the valve and the scale is discharged smoothly.

[0015] Preferably, a curved reserve tube is provided at the upper end of the treatment tube, the length of which is greater than the length of the treatment tube between two adjacent bends. When the treatment tube is pulled, the reserve tube can flexibly straighten to accommodate the change in position of the treatment tube, and the mounting plate cooperates to guide the water inlet end of the treatment tube for smooth movement, preventing unnecessary stress or damage to other connected equipment or components due to excessive bending or pulling.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the fusion electrochemical water treatment device described in the present invention, since both the anode spring and the cathode spring are spiral-shaped, when the treatment tube enters the fold from a straight state, the pitch of the spring will change and deform. At this time, the inner ring of the spring is tight due to compression, while the outer ring is relatively loose. The scale attached to the cathode spring lacks elasticity and cannot deform with the spring. Therefore, the scale layer at the fold position will break and fall off and be carried to the water outlet by the water flow. After the treatment tubes in all straight states are pulled into contact with the roller and deformed, the treatment tubes are released, and the reset spring is deformed and reset, driving the reset block to reset. The reset block pulls the water outlet end of the treatment tube to reset the treatment tube. Repeated pulling and releasing the treatment tube can cause the scale on the cathode spring to break and fall off as much as possible. This design makes cathode descaling quick and convenient, and efficient cleaning can be achieved without disassembling the equipment or shutting down. In addition, the water treatment components are directly integrated into the treatment tube, providing greater installation flexibility. The treatment tubes are arranged on the rollers in the form of wound coils and placed vertically in a flat surface. This not only saves space, but also the coiled layout can cool the circulating water, reduce water evaporation, and delay the increase in salinity caused by evaporation.

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] A fusion electrochemical water treatment device includes a movable base 1 and a treatment tube 2. A mounting plate 3 is fixed to the base 1. Two rows of staggered rollers 4 are provided on the mounting plate 3. The roller surfaces of the rollers 4 are concave. The treatment tube 2 is folded back and connected to the rollers 4 from top to bottom to form a rolling path.

[0028] An inner tube 21 is coaxially arranged inside the processing tube 2. A cathode spring 22 is coaxially arranged between the inner tube 21 and the processing tube 2. An anode spring 23 is coaxially arranged inside the inner tube 21. The cathode spring 22 is connected to the cathode of the power supply, and the anode spring 23 is connected to the anode of the power supply. A small hole 25 is provided on the inner tube 21.

[0029] Both the processing tube 2 and the inner tube 21 are elastic, so that the processing tube 2 and the inner tube 21 can be bent to a certain extent without being damaged.

[0030] Working principle and process:

[0031] The upper end of the treatment tube 2 serves as the water inlet, while the lower end serves as the water outlet. During operation, scale-forming ions such as Ca2+ and Mg2+ in the water, drawn by electrostatic force, gather toward the cathode spring 22, forming precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2. These precipitates accumulate on the surface of the cathode spring 22, forming scale. This weakens the cathode's ionization efficiency and hinders the precipitation of scale-forming ions, resulting in the consumption of electrical energy without effective precipitate removal, and thus, inability to purify the circulating water. At this point, by pulling the outlet end of the treatment tube 2, the roller 4 is driven to rotate, causing the treatment tube 2 to slide along the concave surface of the roller 4. The point of contact between the treatment tube 2 and the roller 4 is the fold, which changes as the treatment tube 2 moves. Because both the anode spring 23 and the cathode spring 22 are helical, when the treatment tube 2 moves from a straight line into the fold, the spring pitch changes, causing deformation. At this point, the inner coil of the spring becomes compact due to compression, while the outer coil becomes relatively loose. However, the scale attached to the cathode spring 22 lacks elasticity and cannot deform with the spring. Therefore, the scale layer at the folded position will break and fall off and be carried to the water outlet by the water flow. This design makes cathode descaling quick and convenient, and efficient cleaning can be achieved without disassembling the equipment or shutting down the machine. In addition, the water treatment component is directly integrated into the treatment pipe 2, providing greater installation flexibility. The treatment pipe 2 is arranged on the roller 4 in the form of a wound coil and placed vertically in a flat shape. It not only saves space, but also this coiled layout can cool the circulating water, reduce the evaporation of water, and delay the increase in salinity caused by evaporation.

[0032] Among them, a reset mechanism is provided at the upper end of the treatment tube 2, which includes a reset block 51, two reset springs 52 and a fixed block 53. The fixed block 53 is provided on the mounting plate 3, and the reset block 51 is fixed to the upper end of the treatment tube 2. Two mutually parallel guide rods 54 are vertically provided on the reset block 51, and the two guide rods 54 are passed through the fixed block 53. The reset block 51 and the fixed block 53 are connected by two reset springs 52, and the two reset springs 52 are respectively coaxially sleeved on the two guide rods 54. When the water outlet end of the treatment tube 2 is pulled until it cannot be pulled further, the reset springs 52 are in a compressed state. At this time, the treatment tube 2 is released, and the reset springs 52 are deformed and reset, driving the reset block 51 to reset. The reset block 51 pulls the water outlet end of the treatment tube 2 to reset the treatment tube 2. Repeated pulling and releasing of the treatment tube 2 can cause the scale on the cathode spring 22 to break and fall off as much as possible.

[0033] Among them, the outer side of the folded part of the processing tube 2 is provided with an arc plate 6, and the arc plate 6 is provided on the mounting plate 3. The arc plate 6 is coaxial with the roller 4 at the corresponding folded part. A plurality of squeezing wheels 7 are installed on the inner side of the arc plate 6. The distance between the squeezing wheel 7 and the bottom of the concave surface of the roller 4 is less than the diameter of the processing tube 2. The inner wall of the processing tube 2 is provided with a protrusion 24. When the processing tube 2 passes through the folded part, the processing tube 2 is compressed by the squeezing wheel 7. As the processing tube 2 is pumped, the squeezing wheel 7 applies pressure to the processing tube 2, causing it to deform. This deformation causes the protrusion 24 on the inner wall of the processing tube 2 to closely contact and squeeze the cathode spring 22, effectively removing the scale layer remaining on the surface of the cathode spring 22 and enhancing the scale cleaning effect.

[0034] Among them, a horizontal square tube 8 is provided at the lower end of the treatment pipe 2, and the lower end of the treatment pipe 2 is connected to the square tube 8. A filter screen 9 is provided in the square tube 8. The cleaned scale is intercepted by the filter screen 9, thereby preventing it from entering the circulation system and avoiding clogging of the treatment pipe 2 due to scale.

[0035] A scraping mechanism is provided inside the square tube 8, comprising a scraper 101, a slider 102, and a slide rod 103. The scraper 101 is provided on the slider 102, which is slidably connected to the slide rod 103. The scraper 101 contacts the surface of the filter screen 9. The scraper 101 slides on the surface of the filter screen 9 to scrape off the structure on the filter screen 9, thereby preventing the filter screen 9 from being clogged by scale.

[0036] The slider 102 is secured with an airbag 11. The square tube 8 has a through-hole on its upper surface, and an elastic membrane 12 is sealed and secured to the inner wall of the through-hole. A lifting plate 13 is secured to the center of the elastic membrane 12. The lifting plate 13 is larger than the through-hole. A pull cord 14 is secured to the bottom of the lifting plate 13. A rotating shaft 15 is located on the inner bottom of the square tube 8, and a pulley 16 is mounted on the rotating shaft 15. The pull cord 14 passes around the bottom of the pulley 16 and is then fixed to the bottom of the slider 102. When the filter 9 becomes clogged due to excessive scale accumulation, water cannot flow smoothly through the filter 9, causing the water pressure in the pipe to gradually increase. As the water pressure increases, the elastic membrane 12 expands upward due to the pressure. This expansion, in turn, drives the connected lifting plate 13 upward. As the lifting plate 13 rises, it pulls the pull cord 14, which in turn pulls a slider 102. Consequently, as the pull cord 14 is pulled, the slider 102 descends along its track. As the slider 102 moves downward, the scraper 101 mounted thereon contacts and scrapes the surface of the filter screen 9, effectively removing any debris or dirt attached to the filter screen 9. Once the debris is removed, the water in the pipe can flow smoothly through the filter screen 9 again, and the water pressure returns to normal. At this point, the elastic membrane 12 elastically resets to its original state due to the loss of external pressure. Simultaneously, due to the buoyancy provided by the airbag 11, the scraper 101 also moves upward under the buoyancy and returns to its initial position. The entire cleaning process is automatic and efficient, ensuring the continued unobstructed flow of the filter screen 9 and the stable operation of the system.

[0037] Below the filter 9 is a collection barrel 17, the top of which is connected to the bottom of the square tube 8. A valve 18 is provided on the barrel 17. The removed scale is successfully intercepted by the filter 9 and stored in the collection barrel 17, effectively preventing it from entering the circulation system. To clean the scale in the collection barrel 17, simply open the valve 18, and the scale is discharged smoothly.

[0038] A curved reserve tube 19 is provided at the upper end of the treatment tube 2. This reserve tube 19 is longer than the length of the treatment tube 2 between two adjacent bends. When the treatment tube 2 is pulled, the reserve tube 19 flexibly straightens to accommodate the change in position of the treatment tube 2. The mounting plate 3 cooperates to guide the water inlet end of the treatment tube 2 for smooth movement, preventing unnecessary stress or damage to other connected equipment or components due to excessive bending or pulling.
