Description

Technical Field

[0001] This utility model relates to the field of circulating water treatment technology, specifically to an electrolytic cell based on electrochemical descaling. Background Technology

[0002] Electrochemical descaling is a highly efficient and environmentally friendly descaling technology. In an electrochemical descaling device, direct current is applied, and water molecules undergo electrolysis under the influence of the electric field. At the cathode, water molecules gain electrons and are reduced, generating hydrogen and hydroxide ions. The electrolytic cell is the core part of the electrochemical reaction, containing an anode and a cathode. The anode often uses special coating materials such as anode rods coated with noble metal oxides, while the cathode is made of a highly conductive material. Other components include a power supply, controller, and cables, which provide a stable direct current to the electrolytic cell, monitor and adjust the electrolysis process, and ensure safe and efficient operation. Advantages include environmental friendliness and energy saving, eliminating the need for large amounts of chemical reagents, reducing environmental pollution and wastewater treatment costs, versatility (simultaneously achieving sterilization, algae removal, and corrosion inhibition), minimal impact on water quality, stable treatment results, relatively low operating costs, easy maintenance, and effective extension of the service life of circulating water systems.

[0003] The circulating water used in the power workshop is prone to scaling, which can clog pipes and instruments, affecting normal production. The current method used is chemical descaling, which removes scale by adding strong acid and alkali agents. This method results in large amounts of wastewater, environmental pollution, equipment corrosion, and high treatment costs. It also has drawbacks such as poor environmental performance, high energy consumption, complex equipment maintenance, and inability to achieve near-zero discharge of circulating water. Furthermore, the existing electrochemical descaling electrolytic cell has a compact cubic space with no room for installing a water inlet dispersion structure. This means that water can only enter directly from the inlet, which prevents the water from being evenly distributed to the surface of each electrode plate, thus reducing the descaling reaction efficiency of the electrode plates. Utility Model Content

[0004] The purpose of this invention is to provide an electrolytic cell based on electrochemical descaling, in order to solve the problems of poor environmental performance, high energy consumption, complex equipment maintenance, inability to achieve near-zero discharge of circulating water, and the inability of the water flow in the electrolytic cell to be evenly distributed to the surface of each electrode plate in the chemical descaling method proposed in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolytic cell based on electrochemical descaling, comprising a processing chamber with grooves on its surface, an upper sealing cover installed on the upper surface of the processing chamber, an electrode assembly fixedly connected to the bottom surface of the grooves in the processing chamber, a power module fixedly installed on the lower surface of the processing chamber, an electromagnetic generator and a magnetic field distributor installed on the outer surface of the processing chamber, a circulating water outlet fixedly connected to the lower surface of the processing chamber, a circulating water inlet fixedly connected to the upper surface of the upper sealing cover, a dispersing water nozzle installed at the lower end of the upper sealing cover, an opening on the side surface of the processing chamber, and a linkage adjustment mechanism installed in the opening of the processing chamber. The mechanism drives a squeezing cam via a drive motor on the surface of a fixed support frame to push a linkage slide plate and a linkage push rod to move the dispersing water nozzle. A water pipe is fixedly connected to the lower surface of the upper sealing cover.

[0006] Preferably, the electrode assembly uses a titanium-based coated anode and a stainless steel cathode, and the electrode assembly is arranged in parallel. The power supply module uses a pulsed DC power supply.

[0007] By adopting the above technical solution, through the titanium-based coated anode and stainless steel cathode of the electrode assembly, the size of the titanium-based coated anode will not change during the electrolysis process, which can ensure that the distance between the electrodes remains stable. This ensures that the electrolysis operation is carried out under a stable cell voltage, which is conducive to maintaining the stability of the electrolysis process and the consistency of product quality. It also has good corrosion resistance and can overcome the problem of dissolution of graphite anodes and lead anodes.

[0008] Preferably, the electromagnetic generator is a strip-shaped design, and the electromagnetic generator is fixed around the outer surface of the processing box, while the magnetic field distributor is located at the corner of the processing box.

[0009] Using the above technical solution, the strip-shaped electromagnetic generator is fixed around the outer surface of the processing box, which can form a relatively uniform magnetic field around the box. Compared with other shapes of electromagnetic generators, the strip design can better cover the surface of the box, reduce dead corners and uneven areas of the magnetic field. The layout around the box allows the magnetic fields of multiple strip-shaped electromagnetic generators to be superimposed, forming a stronger magnetic field around the box. The corners of the processing box are usually weak points in the magnetic field distribution. Placing the magnetic field distributor at the corners can effectively enhance the magnetic field strength in these areas.

[0010] Preferably, the upper sealing cover and the dispersing water outlet are rotatably connected, the upper sealing cover has a water flow guide groove inside, the water flow guide groove of the upper sealing cover is connected to the connecting water pipe, and the connecting water pipe is connected to the dispersing water outlet.

[0011] By adopting the above technical solution, the water flow can be guided along a predetermined path, allowing the water to flow smoothly from the upper closed cover to the connecting water pipe, and then to the dispersed water outlet. This ensures the stability and directionality of the water flow, avoids disordered internal flow, reduces water flow turbulence and energy loss, and connects the water flow guide channel of the upper closed cover to the dispersed water outlet. This enables long-distance water transmission, allowing the water outlet to be set away from the water source or the upper closed cover, increasing the installation flexibility and application range of the water outlet, and meeting the water needs of different scenarios.

[0012] Preferably, the linkage adjustment mechanism includes a linkage slide plate, which is installed in an opening on the side surface of the processing box. A fixed support frame is provided on the side surface of the processing box. A drive motor is fixedly connected to the upper surface of the fixed support frame, and a pressing cam is installed on the lower surface of the fixed support frame. A linkage push rod is connected to the surface of the linkage slide plate.

[0013] The above technical solution provides a stable mounting base for the drive motor and the extrusion cam, ensuring that they maintain a fixed position and posture during operation, avoiding displacement due to vibration or external force, which would affect the normal operation of the entire mechanism. It converts the rotational motion of the drive motor into linear motion or reciprocating motion with a specific pattern, and through cooperation with the linkage slide or linkage push rod, it realizes the control of the extrusion, pushing and other actions required in the processing.

[0014] Preferably, the linkage slide plate and the processing box are slidably connected, and a spring is connected between the linkage slide plate and the processing box. The side surface of the linkage slide plate is in contact with the side surface of the extrusion cam.

[0015] By adopting the above technical solution, the movement of the linkage slide plate is precisely guided, ensuring that it can only move in the direction specified by the processing box, thus guaranteeing the accuracy and stability of the movement. This helps to improve the adjustment accuracy of the entire mechanism and ensure the accuracy of related operations. During the movement of the linkage slide plate, the spring can absorb and buffer the impact force from the extrusion cam or other components, reducing the impact of vibration and shock on the equipment, protecting other components of the equipment from damage, and improving the stability and reliability of the equipment.

[0016] Preferably, the extrusion cam is rotatably connected to the fixed support frame, and the rotating shaft of the extrusion cam passes through the fixed support frame. The upper end of the rotating shaft of the extrusion cam is fixedly connected to the output end of the drive motor. The linkage push rod is rotatably connected to the dispersing nozzle and the linkage slide plate, respectively.

[0017] By adopting the above technical solution, the extrusion cam can rotate stably around a fixed axis. The axis passes through the fixed support frame, making the connection between the extrusion cam and the fixed support frame more stable. This allows the linkage push rod to rotate in different directions and can flexibly transmit the motion of the linkage slide plate to the dispersing nozzle.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the electrolytic cell based on electrochemical descaling:

[0019] 1. Equipped with an electrode assembly and an electromagnetic generator, this device periodically and automatically reverses the polarity of the titanium-coated anode and stainless steel cathode to prevent polarization. During electrolysis, hydrogen ions and active oxygen are generated, reducing and dissolving calcium carbonate or magnesium scale. Electromagnetic mixing field interferes with ion crystallization to prevent the formation of new scale. Finally, suspended solids are adsorbed by chemicals, and calcium and magnesium ions are captured by the negative charge on the electrode surface to form a peelable scale layer. This results in a concentration ratio of more than 8 times, a reduction in sewage discharge of more than 50%, and a 30% improvement in descaling efficiency through dynamic polarity reversal and mixing technology. The cost per ton of water is ≤0.02 yuan, no chemical agents are added, the total phosphorus content is reduced, there is no secondary pollution, and manual intervention is reduced through real-time monitoring and adaptive control.

[0020] 2. Equipped with a dispersing water outlet and a linkage slide plate, this device allows circulating water introduced from the circulating water inlet to be quickly directed to the dispersing water outlet through the connecting water pipe during operation. The arrangement of multiple dispersing water outlets increases the dispersion effect of the circulating water discharge, improves the uniformity of contact between each electrode group and the circulating water, and improves the efficiency of subsequent processing.

[0021] 3. The device is equipped with a squeezing cam and a linkage push rod. When the device is working, the squeezing cam is driven by the drive motor to rotate, which in turn drives the linkage slide plate to move horizontally. The linkage slide plate drives the dispersing water nozzle to rotate through the linkage push rod. This rotation of the dispersing water nozzle during operation further increases the range of circulating water discharge, which is beneficial to increasing the contact area between the circulating water and the electrode assembly, thus improving the processing effect.
