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] The circulating cooling water system uses cooling equipment to lower the temperature of the heated cold water, and then uses a pump to send 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, the scale-forming ions such as Ca2+ and Mg2+ in the water are attracted by electrostatic attraction and gather in the cathode area to form precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2, which eventually deposit and scale on the cathode surface. Therefore, it is necessary to clean the cathode scale regularly.

[0003] The common method of cathode descaling is to add acid solution to the circulating water and use chemical reaction to remove scale, but this method will corrode the cathode and shorten its service life. At the same time, the residual acid will interfere with the water treatment effect and cause corrosion to the pipeline. Another method is to use a hanging plate to mechanically scrape the scale layer on the cathode, but this requires downtime, which will not only cause wear on the cathode surface, but also because the cathode structure is complex and often contains holes, it is difficult to completely remove the scale layer. In addition, this method is labor-intensive and inefficient, affecting overall production efficiency. Traditional electrochemical water treatment devices are bulky, occupy a large space, and lack installation flexibility. Summary of the invention

[0004] In order to solve the defects of the prior art, the present invention provides a fusion electrochemical water treatment device, which does not rely on the addition of acid solution, the cathode descaling process becomes simple and fast, there is no need to interrupt the operation of the equipment, and the descaling efficiency is high. The descaling solution is integrated with the pipeline system, saving space, and the installation process is flexible and changeable.

[0005] The technical solution adopted by the present invention is: comprising a movable base and a processing tube, the base is fixed with a mounting plate, the mounting plate is provided with two rows of staggered rollers, the wheel surface of the roller is a concave surface, the processing tube is folded back and connected to the roller from top to bottom in sequence 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, the cathode spring is connected to the cathode of the power supply, and a small hole is arranged on the inner tube;

[0007] The processing tube and the inner tube are both elastic, so that the processing tube and the inner tube 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, the scale-forming ions such as Ca2+ and Mg2+ in the water gather toward the cathode spring under the traction of electrostatic force, and then form precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2, and accumulate scale on the surface of the cathode spring, which will weaken the ionization efficiency of the cathode and hinder the precipitation of scale-forming ions, resulting in only consuming electrical energy but unable to effectively remove the precipitates, and unable to achieve the purification of circulating water. At this time, by pulling the water outlet end of the treatment tube, the roller is driven to rotate, and the treatment tube slides along the concave surface of the roller. The contact point between the treatment tube and the roller is the folding point, and this folding point changes with the movement of the treatment tube. Since both the anode spring and the cathode spring are spiral, when the treatment tube enters the folding point from a straight state, the pitch of the spring will change and deformation will occur. At this time, the inner ring of the spring is tight due to extrusion, and 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 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 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 surface. 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.

[0009] Preferably, a reset mechanism is provided at the upper end of the treatment tube, and the reset mechanism includes a reset block, two reset springs and a fixed block, the fixed block is provided on the mounting plate, the reset block is fixed on the upper end of the treatment tube, two mutually parallel guide rods are vertically provided on the reset block, the two guide rods are passed through the fixed block, the reset block and the fixed block are connected by two reset springs, and the two reset springs are coaxially sleeved on the two guide rods respectively. When the water outlet end of the treatment tube is pulled until it cannot be pulled, the reset spring is in a compressed state, and the treatment tube is released at this time, the reset spring is deformed and reset, 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 repeatedly pulling and releasing the treatment tube can make the scale on the cathode spring break and fall off as much as possible.

[0010] Preferably, the outer side of the folded part of the treatment tube is provided with an arc plate, the arc plate is provided on the mounting plate, the arc plate is coaxial with the roller at the corresponding folded part, a plurality of extrusion wheels are installed on the inner side of the arc plate, the distance from the extrusion wheel to the bottom of the concave surface on the roller is less than the diameter of the treatment tube, and a protrusion is provided on the inner wall of the treatment tube. When the treatment tube passes through the folded part, the treatment tube is compressed by the extrusion wheel, and as the treatment tube is pumped, the extrusion wheel applies pressure to the treatment tube, causing it to deform, and this deformation makes the protrusion on the inner wall of the treatment tube closely contact and squeeze the cathode spring, effectively removing the scale layer remaining on the surface of the cathode spring, and enhancing the descaling 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 to prevent it from entering the circulation system, thus avoiding clogging of the treatment tube due to scale.

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

[0013] Preferably, an air bag is fixed on the slider, a through hole is provided on the upper surface of the square tube, an elastic membrane is sealed and fixed on the inner wall of the through hole, a lifting plate is fixed at the center of the elastic membrane, the area of ​​the lifting plate is larger than the area of ​​the through hole, a pull rope is fixed at the bottom of the lifting plate, a rotating shaft is provided at the bottom of the inner side of the square tube, a pulley is provided on the rotating shaft, and the pull rope is fixedly connected to the bottom of the slider after passing around the bottom of the pulley. When the filter screen is blocked due to excessive accumulation of scale, the water flow cannot pass through the filter screen smoothly, which will cause the water pressure in the pipeline to gradually increase. As the water pressure increases, the elastic membrane will expand upward due to the pressure. This expansion action will then drive the lifting plate connected to it to rise. During the process of rising, the lifting plate will pull the pull rope, and the other end of the pull rope will pull a slider. Therefore, as the pull rope is pulled, the slider will move down along its track. When the slider moves down, the scraper installed on it will contact and scrape the surface of the filter screen, effectively scraping off the dirt attached to the filter screen. Once the dirt is cleaned, the water in the pipe can flow smoothly through the filter again, and the water pressure will return to normal. At this time, the elastic membrane will elastically reset to its original state due to the loss of external pressure. At the same time, due to the buoyancy provided by the airbag, the scraper will also move upward under the buoyancy and return to its initial position. The entire cleaning process is automatic and efficient, ensuring the continuous unobstructed flow of the filter and the stable operation of the system.

[0014] Preferably, a collecting cylinder is provided below the filter screen, the top of the collecting cylinder is connected to the bottom of the square tube, and a valve is provided on the collecting cylinder. The removed scale is successfully intercepted by the filter screen and falls into the collecting cylinder for storage, which effectively prevents the scale from entering the circulation system. When the scale in the collecting cylinder needs to be cleaned, the scale can be discharged smoothly by simply opening the valve.

[0015] Preferably, a curved reserved pipe is provided at the upper end of the treatment pipe, and the length of the reserved pipe is greater than the length of the treatment pipe between two adjacent folds. When the treatment pipe is pulled, the reserved pipe can be flexibly straightened to adapt to the position change of the treatment pipe, and the mounting plate cooperates to guide the water inlet end of the treatment pipe to move smoothly, without causing 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] The fusion electrochemical water treatment device described in the present invention has a spiral shape because the anode spring and the cathode spring are both spiral. When the treatment tube enters the folding part from the straight state, the pitch of the spring will change and deform. At this time, the inner ring of the spring is tight due to extrusion, and 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 folding part will break and fall off and be carried to the water outlet by the water flow. After the treatment tube in the straight state is pulled to contact and deform with the roller, the treatment tube is released, the reset spring is deformed and reset, and the reset block is 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 make the scale on the cathode spring 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 stopping the machine. In addition, the water treatment component is directly integrated into the treatment tube, providing higher installation flexibility. The treatment tubes are arranged on the rollers in the form of wound coils and placed vertically in a flat plane. This not only saves space, but the coiled layout can also cool the circulating water, reduce the evaporation of water, and delay the increase in salinity caused by evaporation.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with 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 comprises a movable base 1 and a treatment tube 2, a mounting plate 3 is fixed on the base 1, two rows of staggered rollers 4 are arranged on the mounting plate 3, the wheel surface of the roller 4 is a concave surface, and the treatment tube 2 is folded back and wound around the roller 4 in sequence 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, the anode spring 23 is connected to the anode of the power supply, and a small hole 25 is arranged 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, and the lower end serves as the water outlet. During operation, the ions such as Ca2+ and Mg2+ in the water that are easy to form scale gather toward the cathode spring 22 under the traction of the electrostatic force, and then form precipitates such as CaCO3, MgCO3, Ca(OH)2, and Mg(OH)2, and accumulate scale on the surface of the cathode spring 22, which will weaken the ionization efficiency of the cathode and hinder the precipitation of scale ions, resulting in only consuming electrical energy but unable to effectively remove the precipitates, and unable to achieve the purification of circulating water. At this time, by pulling the water outlet end of the treatment tube 2, the roller 4 is driven to rotate, and the treatment tube 2 slides along the concave surface of the roller 4. The contact point between the treatment tube 2 and the roller 4 is the folding point, and as the treatment tube 2 moves, this folding point also changes. Since the anode spring 23 and the cathode spring 22 are both spiral, when the treatment tube 2 enters the folding point from the straight state, the pitch of the spring will change and deformation will occur. At this time, the inner circle of the spring is tight due to extrusion, and the outer circle is relatively loose. 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. In addition, the water treatment component is directly integrated into the treatment tube 2, providing greater installation flexibility. The treatment tube 2 is arranged on the roller 4 in the form of a wound coil and placed vertically in a flat shape, which 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 arranged at the upper end of the treatment tube 2, and the reset mechanism comprises a reset block 51, two reset springs 52 and a fixed block 53. The fixed block 53 is arranged on the mounting plate 3, and the reset block 51 is fixed at the upper end of the treatment tube 2. Two mutually parallel guide rods 54 are vertically arranged on the reset block 51, and the two guide rods 54 are penetrated on 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 to the point where it cannot be pulled, the reset spring 52 is in a compressed state. At this time, the treatment tube 2 is released, and the reset spring 52 is 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 make the scale on the cathode spring 22 break and fall off as much as possible.

[0033] Among them, arc plates 6 are arranged on the outer side of the folded part of the treatment tube 2, and the arc plates 6 are arranged on the mounting plate 3. The arc plates 6 are coaxial with the rollers 4 at the corresponding folded part, and a plurality of extrusion wheels 7 are installed on the inner side of the arc plates 6. The distance from the extrusion wheels 7 to the bottom of the concave surface on the rollers 4 is less than the diameter of the treatment tube 2, and a protrusion 24 is arranged on the inner wall of the treatment tube 2. When the treatment tube 2 passes through the folded part, the treatment tube 2 is pressed by the extrusion wheels 7. With the pumping action of the treatment tube 2, the extrusion wheels 7 exert pressure on the treatment tube 2, causing it to deform. This deformation makes the protrusion 24 on the inner wall of the treatment tube 2 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] The lower end of the treatment tube 2 is provided with a horizontal square tube 8, the lower end of the treatment tube 2 is connected to the square tube 8, and 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, avoiding the blockage of the treatment tube 2 due to scale.

[0035] Among them, a scraping mechanism is arranged in the square tube 8, and the scraping mechanism includes a scraper 101, a slider 102 and a slide bar 103. The scraper 101 is arranged on the slider 102, and the slider 102 is slidably connected to the slide bar 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, so as to prevent the filter screen 9 from being blocked by scaling.

[0036] Among them, an air bag 11 is fixed on the slider 102, a through hole is provided on the upper surface of the square tube 8, an elastic membrane 12 is sealed and fixed on the inner wall of the through hole, a lifting plate 13 is fixed at the center of the elastic membrane 12, the area of ​​the lifting plate 13 is larger than the area of ​​the through hole, a pull rope 14 is fixed at the bottom of the lifting plate 13, a rotating shaft 15 is provided at the bottom of the inner side of the square tube 8, a pulley 16 is provided on the rotating shaft 15, and the pull rope 14 is fixedly connected to the bottom of the slider 102 after passing the bottom of the pulley 16. When the filter screen 9 is blocked due to excessive accumulation of scale, the water flow cannot pass through the filter screen 9 smoothly, which will cause the water pressure in the pipeline to gradually increase. As the water pressure increases, the elastic membrane 12 will expand upward due to the pressure. This expansion action will then drive the lifting plate 13 connected thereto to rise. During the process of rising, the lifting plate 13 will pull the pull rope 14, and the other end of the pull rope 14 will pull a slider 102. Therefore, as the pull rope 14 is pulled, the slider 102 will move down along its track. When the slider 102 moves downward, the scraper 101 installed thereon will contact and scrape the surface of the filter screen 9, effectively scraping off the dirt attached to the filter screen 9. Once the dirt is cleaned, the water flow in the pipeline can pass through the filter screen 9 smoothly again, and the water pressure will return to normal levels. At this time, the elastic membrane 12 will elastically reset to its original state due to the loss of external pressure. At the same time, due to the buoyancy provided by the airbag 11, the scraper 101 will also move upward under the action of buoyancy and return to its initial position. The entire cleaning process is automatic and efficient, ensuring the continuous smooth flow of the filter screen 9 and the stable operation of the system.

[0037] A collecting cylinder 17 is provided below the filter screen 9, the top of the collecting cylinder 17 is connected to the bottom of the square tube 8, and a valve 18 is provided on the collecting cylinder 17. The removed scale is successfully intercepted by the filter screen 9 and falls into the collecting cylinder 17 for storage, which effectively prevents the scale from entering the circulation system. When the scale in the collecting cylinder 17 needs to be cleaned, the valve 18 is simply opened and the scale can be discharged smoothly.

[0038] A curved reserved pipe 19 is provided at the upper end of the treatment pipe 2, and the length of the reserved pipe 19 is greater than the length of the treatment pipe 2 between two adjacent folds. When the treatment pipe 2 is pulled, the reserved pipe 19 can be flexibly straightened to adapt to the position change of the treatment pipe 2, and the mounting plate 3 cooperates to guide the water inlet end of the treatment pipe 2 to move smoothly, without causing unnecessary stress or damage to other connected equipment or components due to excessive bending or pulling.
