Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an easy-to-maintain electrochemical water treatment device. Background Technology

[0002] Electrochemical water treatment technology utilizes the electrochemical interaction between electrodes and an electrolyte (water to be treated) to purify water through multiple mechanisms such as oxidation-reduction reactions, flocculation, flotation, and adsorption. During the electrochemical water treatment process, scale is generated and adheres to the cathode plate. To ensure the normal operation of the system, this scale is typically removed using a scraper. The anode plate also requires maintenance during use. While some water treatment equipment on the market can lift the anode plate from the reaction wall for maintenance, this presents a problem of inconvenient inspection and maintenance.

[0003] For example, Chinese Patent Application No. CN202021940688.9 discloses an electrochemical circulating water treatment device, comprising a cylinder, a support frame, and a hydraulic cylinder installed sequentially from bottom to top. An electrical control system is installed inside the cylinder. An inlet pipe and a drain pipe are connected to the bottom of the cylinder, and an outlet pipe is connected to the top of the cylinder. A positive electrode extends from the axis of the cylinder, and a negative electrode is installed on the inner wall of the cylinder. The hydraulic cylinder, the positive electrode, and the negative electrode are all connected to the electrical control system. A scraper is installed inside the cylinder, abutting against the negative electrode. The scraper is connected to the hydraulic cylinder, and the hydraulic cylinder drives the scraper to reciprocate up and down along the inner wall of the cylinder. In this design, the anode plate is immersed in water, making it impossible to lift the anode plate for maintenance and inspection, resulting in inconvenient maintenance. Utility Model Content

[0024] Please refer to Figures 1 to 4As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is an easy-to-maintain electrochemical water treatment device.

[0025] When the first locking rod 49 hinged on the anode box 41 is engaged with the first locking buckle 32 on the scraper holder 31, the scraper holder rises and the anode box 41 also rises synchronously. This design makes the maintenance and repair of the anode plate 410 more convenient.

[0026] This application provides an easy-to-maintain electrochemical water treatment device, including a cylinder 10, a lifting device 20, a scraper device 30, and an electrode device 40. A sedimentation hopper 11 is provided at the bottom of the cylinder 10, and a drain port 17 is provided on the sedimentation hopper 11. The lifting device 20 is provided on the cylinder 10 and is connected to the scraper device 30. The scraper device 30 includes a scraper holder 31 and a scraper mounted on the scraper holder 31. The electrode device 40 includes an anode box 41, an anode plate 410 removably mounted inside the anode box 41, and a reaction wall 411 mounted on the inner wall of the cylinder 10. A first locking rod 49 is hinged to the anode box 41, and a first locking buckle 32 is provided on the scraper holder 31. The first locking rod 49 is engaged with the first locking buckle 32. The anode box 41 moves up and down with the scraper holder, and the scraper can scrape away the dirt on the reaction wall 411. The cylinder 10 is a metal cylinder 10. The interior of the cylinder 10 is coated with a reaction wall 411, which serves as the cathode. The reaction wall 411 can be made of metal materials such as stainless steel, titanium, iron, and aluminum, or conductive inorganic materials such as carbon. The lifting device 20 can lift the scraper device 30. When the scraper frame 31 moves up and down, the scraper removes dirt from the reaction wall 411. When the anode plate 410 needs to be inspected, the worker uses their hand or a hook to engage the first locking rod 49 with the first locking buckle 32, so that when the scraper frame 31 is lifted, the anode box 41 rises synchronously. Since the anode plate 410 is installed inside the anode box 41, the anode box 41 is raised, making it convenient for workers to maintain and inspect the anode plate 410. When the anode plate 410 needs to be inspected, the worker removes the anode plate 410 from the anode box 41 for cleaning and maintenance. The first locking rod 49 can be an L-shaped rod. The first locking rod 49 swings on the anode box 41, thereby engaging with the first latch 32. This design is very convenient. At least two first locking rods 49 and first latches 32 are grouped together to ensure balanced force on the anode box 41. In this embodiment, the anode plate 410 is made of metal.

[0027] Preferably, the lifting device 20 includes a first hydraulic cylinder 21, a second hydraulic cylinder 22, and a cylinder cover 23; the first hydraulic cylinder 21 and the second hydraulic cylinder 22 are mounted on the cylinder cover 23; the output end of the first hydraulic cylinder 21 is connected to the scraper holder 31, and the first hydraulic cylinder 21 can lift the scraper holder 31; the output end of the second hydraulic cylinder 22 is connected to the mounting seat 18 on the inner wall of the cylinder 10, and the second hydraulic cylinder 22 can lift the cylinder cover 23.

The output end of the second hydraulic cylinder 22 is mounted on the mounting seat on the inner wall of the cylinder 10. When the drive shaft of the second hydraulic cylinder 22 extends, the cylinder cover 23 will be lifted. This design allows the cylinder cover 23 to be lifted, which in turn raises the scraper holder 31 and the anode box 41 to a certain height. This design further facilitates workers to inspect and maintain the anode plate 410.

[0028] Preferably, the feature is that: an inspection door 24 is provided on the cylinder cover 23, and a first sealing ring is fitted on the inspection door 24; a cylindrical ring 25 is provided on the bottom surface of the cylinder cover 23, and a second sealing ring 26 is provided inside the cylindrical ring 25, with the cylindrical ring 25 fitted on the top of the cylinder body 10.

The first scraper 35 is disposed on the elastic plastic 34, and its extension is greater than that of the second scraper 36. Because the elastic plastic 34 is elastic, when encountering thicker dirt, the first scraper 35 will scrape away the dirt layer by layer first, avoiding cutting too deeply. Therefore, with the combined action of the first scraper 35 and the second scraper 36, the wear of the scraper can be reduced, and the service life of the scraper can be improved.

[0030] Preferably, the anode box 41 includes a box body 42, an ion exchange membrane 43, a box side plate 44, and a third sealing ring 45; the box body 42 and the box side plate 44 have through holes 46; the third sealing ring 45 is disposed in a sealing groove on the side of the box body 42; the box side plate 44 presses the ion exchange membrane 43 onto the box body 42.

[0032] Preferably, the inner wall of the sedimentation tank 11 is provided with a plurality of cleaning nozzles 12 facing the drain outlet. The cleaning nozzles 12 can spray water at a certain pressure to clean the sedimentation tank 11 and prevent dirt from accumulating inside the sedimentation tank.
