Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a novel scraper lifting device for electrochemical descaling and purification equipment. Background Technology

[0002] Electrochemical descaling and purification equipment has functions such as descaling, scale inhibition, sterilization, and algae removal. It can replace traditional agents, reduce the water demand and sewage discharge of the circulating system, and significantly reduce system energy consumption, treatment costs, and labor input. It has four major advantages: comprehensive functions, high efficiency and convenience, green environmental protection, and cost reduction. When direct current is conducted to the cooling circulating water through the titanium anode, the following reaction occurs: near the cathode, a high concentration of hydroxide ions (OH-) is formed. - This high pH environment will cause non-scaling minerals (such as calcium) in the water to... 2+ Mg 2+ The scale forms beforehand and precipitates from the water, depositing onto the cathode plate, thus softening the water. Simultaneously, hydroxyl radicals (-OH) are generated at the anode, releasing chloride ions (Cl-). - The ions are converted into free chlorine, and some hydroxide ions are converted into trace amounts of ozone. These strong oxidizing substances can inhibit the growth of bacteria and algae in the circulating water system, achieving the functions of sterilization, disinfection, and algae removal. At the same time, they can also remove calcium from the water. 2+ Mg 2+ After being adsorbed onto the cathode plate in solid form, it is removed, thus reducing the hardness of the water.

[0003] Special electrodes with electrocatalytic function are used to generate active chlorine, active oxygen, and free radicals during direct current electrolysis to kill bacteria and algae and prevent their growth. For example, the chlorine evolution reaction: 2Cl... - +2e→Cl2 (gas). During electrolysis, hydrogen evolution occurs at the cathode, generating hydroxide ions and creating a strongly alkaline environment in the cathode region, which promotes the precipitation of calcium and magnesium ions in the water. For example, the cathode reaction: 2H2O + 2e→H2 + 2OH- - Hydrolysis reaction: Ca 2+ +HCO3 - +H - →CaCO3 + H2O, Mg 2+ +2OH - →Mg(OH)2. After energizing, calcium carbonate, magnesium carbonate, magnesium hydroxide, and other scale deposits are generated, and some sludge is adsorbed onto the cathode plate. The electrolytic cell is arranged with fixed anode and cathode plates, and a scraper assembly moves vertically up and down to scrape off the scale deposits and some sludge adsorbed on the cathode plate.

[0004] Traditional scraper lifting devices use hydraulic power to drive the scraper assembly for vertical movement. Due to the compressibility of hydraulic fluid and the elasticity of the system (such as oil pipe expansion), its rigidity and accuracy are relatively poor. A "creeping" phenomenon occurs, making it difficult to achieve strictly precise positioning. Hydraulic transmission has a response delay; electrical signals control hydraulic valves, which in turn drive the cylinders. The process of hydraulic oil flow and pressure build-up involves time lag and a relatively slow response speed, often resulting in asynchronous operation between the two cylinders. This leads to height differences and uneven force distribution across the scraper assembly. Hydraulic transmission energy requires multiple conversions through the motor, pump, hydraulic oil, and actuator, resulting in throttling losses, overflow losses, and leakage losses. The overall efficiency is typically only 60%-80% or even lower. Even under pressure holding conditions, the motor and pump may need to operate continuously, leading to high energy consumption. Hydraulic oil leakage is also a common problem, polluting the environment and products, posing a serious defect for industries such as food, pharmaceuticals, and electronics. The system requires regular replacement of hydraulic oil and filters, making fault diagnosis and maintenance more complex. Finally, the overall cost of a hydraulic system is high. Utility Model Content

[0005] The purpose of this invention is to provide a novel scraper lifting device for electrochemical descaling and purification equipment. This addresses the problems of traditional scraper lifting devices that use hydraulically driven scraper assemblies for vertical movement. Due to the compressibility of hydraulic fluid and the elasticity of the system (such as oil pipe expansion), the rigidity and accuracy are relatively poor. A "creeping" phenomenon exists, making precise positioning difficult. Hydraulic transmission has a response delay; the electrical signal controls the hydraulic valve, which drives the cylinder. The process of hydraulic oil flow and pressure build-up involves a time lag, resulting in a relatively slow response speed. Therefore, the two cylinders often become asynchronous, leading to height differences and uneven force distribution across the scraper assembly. Hydraulic transmission energy requires multiple conversions through the motor, pump, hydraulic oil, and actuator, resulting in throttling losses, overflow losses, and leakage losses. The overall efficiency is typically only 60%-80% or even lower. Even under pressure holding conditions, the motor and pump may need to operate continuously, leading to high energy consumption. Hydraulic oil leakage is also a common problem, polluting the environment and products, posing a serious defect for industries such as food, pharmaceuticals, and electronics. The system requires regular replacement of hydraulic oil and filters, and fault diagnosis and maintenance are more complex. Finally, there is the issue of the high overall cost of the hydraulic system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel scraper lifting device for electrochemical descaling and purification equipment, comprising an electrolytic cell, a support foot fixedly connected to the lower end of the electrolytic cell, a rack slidably connected inside the electrolytic cell, a gear meshing on the outer side of the rack, a lifting beam fixedly connected to the upper end of the rack, a scraper assembly provided at the lower end of the lifting beam, and a drive mechanism provided on the electrolytic cell.

[0007] Preferably, the driving mechanism includes a support plate, the support plate is fixedly connected to the surface of the electrolytic cell, a support shaft is installed inside the support plate via bearings, the support shaft is fixedly connected to a gear, a sprocket is fixedly connected to the end of the support shaft, a chain is meshed on the outer side of the sprocket, a motor is fixedly installed on the surface of the electrolytic cell, an mounting plate is fixedly connected to the surface of the electrolytic cell, a screw is installed inside the mounting plate via bearings, a screw cylinder is threaded to the outer side of the screw, a slide cylinder is slidably connected to the outer side of the screw cylinder, a slide plate is fixedly connected to the upper end of the slide cylinder, the slide plate is slidably connected to the electrolytic cell, a spring is provided inside the slide cylinder, and a connecting shaft is installed inside the slide plate via bearings. The motor drives the drive sprocket, which in turn rotates the chain, causing the two sprockets to rotate synchronously. This, in turn, causes the support shaft to drive the two gears to rotate synchronously, which in turn causes the two racks to move synchronously. This allows the lifting beam to move stably up and down, which in turn moves the scraper assembly up and down. The height of the scraper assembly can be adjusted by manually rotating the screw and the screw barrel to create a threaded motion. This causes the screw barrel to compress the spring, which in turn causes the spring to elastically compress the sliding plate, which in turn moves the guide wheel to tighten the chain. This keeps the chain taut and prevents it from loosening, thus making the device drive more stable.

[0008] Preferably, a drive sprocket is fixedly connected to the end of the motor shaft, and the drive sprocket meshes with the chain. By setting the drive sprocket, the rotation of the chain is controlled.

[0009] Preferably, a sliding pin is fixedly connected to the surface of the screw cylinder, and the sliding pin and the slide cylinder are slidably connected. By providing the sliding pin, relative rotation between the screw cylinder and the slide cylinder is prevented.

[0010] Preferably, one end of the spring is fixedly connected to the screw cylinder, and the other end of the spring is fixedly connected to the slide plate. The spring provides elastic compression to the slide plate.

[0011] Preferably, a guide wheel is fixedly connected to the surface of the connecting shaft, and the guide wheel contacts the chain. By setting the guide wheel, the chain is compressed and tensioned.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a drive sprocket to rotate a chain, which in turn causes two sprockets to rotate synchronously. This, in turn, causes the support shaft to drive two gears to rotate synchronously, which in turn causes two racks to move synchronously. This allows the lifting beam to move stably up and down, which in turn moves the scraper assembly up and down, adjusting the height of the scraper assembly. This method is economical and has a high cost-performance ratio.

[0014] 2. This utility model uses manual rotation of the screw and screw barrel to create a threaded motion, which causes the screw barrel to compress the spring. The spring then compresses the sliding plate, which in turn moves the guide wheel to tighten the chain, thus keeping the chain taut and preventing it from loosening. This makes the device drive more stable. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-3 A novel scraper lifting device for electrochemical descaling and purification equipment includes an electrolytic cell 1, a support leg 2 fixedly connected to the lower end of the electrolytic cell 1, a rack 3 slidably connected inside the electrolytic cell 1, a gear 4 meshing on the outer side of the rack 3, a lifting beam 5 fixedly connected to the upper end of the rack 3, a scraper assembly 6 provided at the lower end of the lifting beam 5, and a drive mechanism 7 provided on the electrolytic cell 1.

[0022] Please see Figure 3 , Figure 4The drive mechanism 7 includes a support plate 71. The support plate 71 is fixedly connected to the surface of the electrolytic cell 1. A support shaft 72 is installed inside the support plate 71 through a bearing. The support shaft 72 is fixedly connected to a gear 4. A sprocket 73 is fixedly connected to the end of the support shaft 72. A chain 74 is meshed on the outside of the sprocket 73. A motor 75 is fixedly installed on the surface of the electrolytic cell 1. A drive sprocket 76 is fixedly connected to the end of the shaft of the motor 75. The drive sprocket 76 meshes with the chain 74. By setting the drive sprocket 76, the rotation of the chain 74 is controlled.

[0023] Please see Figures 1-2 An installation plate 77 is fixedly connected to the surface of the electrolytic cell 1. A screw 78 is mounted inside the installation plate 77 via bearings. A screw cylinder 79 is threadedly connected to the outside of the screw 78. A slide cylinder 710 is slidably connected to the outside of the screw cylinder 79. A sliding pin 711 is fixedly connected to the surface of the screw cylinder 79, and the sliding pin 711 and the slide cylinder 710 are slidably connected. By setting the sliding pin 711, relative rotation between the screw cylinder 79 and the slide cylinder 710 is prevented. A slide plate 712 is fixedly connected to the upper end of the slide cylinder 710, and the slide plate 712 is slidably connected to the electrolytic cell 1. A spring 713 is installed inside the slide cylinder 710. One end of the spring 713 is fixedly connected to the screw cylinder 79, and the other end of the spring 713 is fixedly connected to the slide plate 712. By setting the spring 713, the slide plate 712 is elastically compressed. A connecting shaft 71 is mounted inside the slide plate 712 via bearings. 4. A guide wheel 715 is fixedly connected to the surface of the connecting shaft 714. The guide wheel 715 contacts the chain 74. By setting the guide wheel 715, the chain 74 is compressed and tensioned. The motor 75 drives the drive sprocket 76 to rotate the chain 74, which in turn causes the two sprockets 73 to rotate synchronously. This causes the support shaft 72 to drive the two gears 4 to rotate synchronously, which in turn causes the two racks 3 to move synchronously. This allows the lifting beam 5 to move up and down stably, which in turn causes the scraper assembly 6 to move up and down. The height of the scraper assembly 6 can be adjusted by manually rotating the screw 78 and the screw barrel 79 to make a threaded movement. This causes the screw barrel 79 to compress the spring 713, which in turn causes the spring 713 to elastically compress the sliding plate 712, which in turn causes the guide wheel 715 to move and press the chain 74 tight. This keeps the chain 74 taut and prevents it from loosening, thus making the device drive more stable.

[0024] The specific implementation process of this utility model is as follows: In use, the motor 75 is started, driving the drive sprocket 76. The drive sprocket 76 drives the chain 74 to move, the chain 74 drives the sprocket 73 to rotate, the sprocket 73 drives the support shaft 72 to rotate, the support shaft 72 drives the gear 4 to rotate, and the gear 4 drives the rack 3 to move. This causes the rack 3 to slide within the guide seat on the side of the electrolytic cell 1. The rack 3 drives the lifting beam 5 to move, and the lifting beam 5 drives the scraper assembly 6 to move, causing the scraper assembly 6 to change height. The motor 75 drives the drive sprocket 76 to drive the chain 74 to rotate, causing the two sprockets 73 to rotate synchronously. This causes the support shaft 72 to drive the two gears 4 to rotate synchronously, and the two racks 3 to move synchronously, allowing the lifting beam 5 to move up and down stably. The fixed movement drives the scraper assembly 6 to move up and down, adjusting the height of the scraper assembly 6. In use, the screw 78 is manually rotated, causing the screw 78 and the screw barrel 79 to rotate in a threaded motion, which in turn causes the screw barrel 79 to move upward. The upward movement of the screw barrel 79 compresses the spring 713, which in turn causes the spring 713 to elastically compress the slide plate 712. The slide plate 712 drives the connecting shaft 714 to move upward, which in turn drives the guide wheel 715 to move upward, which in turn causes the guide wheel 715 to compress the chain 74. By manually rotating the screw 78 and the screw barrel 79 in a threaded motion, the screw barrel 79 compresses the spring 713, which in turn causes the spring 713 to elastically compress the slide plate 712, which in turn causes the guide wheel 715 to move and press the chain 74 tight, thus keeping the chain 74 taut and preventing it from loosening, thereby making the device drive more stable.
