Description

Technical Field

[0001] This utility model relates to the field of electrochemical water treatment technology, and in particular to an electrochemical descaling device with a quick-replaceable electrode assembly. Background Technology

[0002] The main principle of electrochemical water softening is to apply a certain voltage to the electrodes, generating a large number of hydroxide ions at the interface between the cathode and water. This causes bicarbonate ions to convert into carbonate ions, resulting in supersaturation of calcium carbonate and magnesium hydroxide near the cathode, which then precipitates out, thus achieving descaling. Traditional electrochemical descaling devices typically install electrodes in the reaction chamber using bolts or wire welding. Replacement requires stopping the machine, purging, disassembling pipes or the casing, disconnecting wires, removing the old electrode, installing a new electrode, and resealing and rewiring. The entire process is cumbersome, requires highly skilled operators, and involves long downtime. Therefore, this invention proposes an electrochemical descaling device with a quickly replaceable electrode assembly. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Furthermore, the electrode mounting mechanism includes a base, a back plate is provided on one side of the upper end face of the base, and a plurality of spacers 1 and 2 are alternately distributed on the front side of the back plate, with the other ends of spacers 1 and 2 disposed on the base; a gap is left between adjacent spacers 1 and 2 for the anode plate / cathode plate to be inserted; mounting brackets are respectively provided at the left and right ends of the base, and the mounting brackets are provided with threaded holes that match the long bolts.

[0007] Furthermore, both the first and second partitions are inverted L-shaped structures, and together with the base and back plate, they form holes through which the long bolts pass.

[0008] Furthermore, both the anode plate and the cathode plate are provided with large holes for the long bolts to pass through.

[0009] Furthermore, the terminal assembly includes a hollow square groove, with through holes on the front and rear end faces of the square groove for the long bolt to pass through, and a terminal block that contacts the long bolt is disposed above the square groove.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This novel electrochemical descaling device with quickly replaceable electrode assemblies achieves rapid electrode replacement by inserting the anode and cathode plates into the electrode mounting mechanism and connecting them with long bolts for power supply. This reduces electrode replacement time to minutes, minimizing equipment downtime. Furthermore, it eliminates the need for professional personnel and avoids secondary damage to components such as the casing during traditional disassembly, significantly reducing labor costs and additional failure risks. It can also promptly replace anodes and other components that fail due to oxidation or scaling, preventing reduced descaling efficiency and substandard water quality caused by single electrode issues, ensuring stable equipment operation. Moreover, it allows for targeted replacement of consumable parts, avoiding the need to replace the entire module due to individual electrode failure. Additionally, it supports flexible replacement of electrode assemblies of different materials or quantities based on water quality changes, enhancing the device's adaptability to various scenarios and optimizing usage costs and user experience from multiple dimensions, including maintenance, operation, and lifespan.

[0024] like Figure 1-5 As shown, an electrochemical descaling device with quick-replacement electrode assembly includes a housing 1. The top of the housing 1 has an outlet 7, and the bottom has a slag discharge port 8 and an inlet 9. Inside the housing 1, alternating anode plates 11 and cathode plates 12 are installed. Both anode plates 11 and cathode plates 12 are mounted on symmetrically distributed electrode mounting mechanisms 2, which are connected together by connecting rods 10. On the outside of the housing 1, a terminal assembly 4 matching the anode plates 11 and cathode plates 12 is installed. The terminal assembly 4 connects the electrode mounting mechanisms 2 and the anode plates 11 / cathode plates 12 by long bolts 3 passing through the housing 1.

[0025] The electrode mounting mechanism 2 includes a base 201. A back plate 202 is mounted on one side of the upper surface of the base 201. Several spacers 1 203 and 204 are alternately distributed on the front side of the back plate 202. The other ends of the spacers 1 203 and 204 are mounted on the base 201. A gap is left between adjacent spacers 1 203 and 204 for the anode plate 11 / cathode plate 12 to be inserted. The distance between the electrode plates can be adjusted by inserting the plates into different gaps, and the distance is equidistant, allowing for quick disassembly and installation, and convenient operation. Mounting brackets 205 are mounted on the left and right ends of the base 201, respectively. The mounting brackets 205 have threaded holes 206 that match the long bolts 3, and the threaded holes 206 fix and limit the long bolts 3. The spacers 1 203 and 204 are both inverted L-shaped structures, and form holes with the base 201 and back plate 202 for the long bolts 3 to pass through.

[0026] Both the anode plate 11 and the cathode plate 12 have large holes for the long bolts 3 to pass through. The long bolts 3 are made of metal and are conductive, thus ensuring that all plates are energized.

[0027] The terminal assembly 4 includes a hollow square groove 401. Through holes 402 are provided on the front and rear end faces of the square groove 401 for the long bolt 3 to pass through. A terminal 404 is installed above the square groove 401 to contact the long bolt 3. Mounting seats 403, which connect to the outer casing 1, are symmetrically installed on the left and right end faces of the square groove 401.

[0028] The outer casing 1 is made of insulating material.

[0029] A platform 6 is symmetrically installed on the outer side wall of the electrode mounting mechanism 2 located above, and a support 5 that cooperates with the platform 6 is symmetrically installed on the inner side wall of the outer shell 1.

[0030] The working process of this utility model is as follows:

[0031] First, connect the positive electrode of the DC constant current source to the terminal assembly 4 on the anode plate 11, and connect the cathode to the terminal assembly 4 on the cathode plate 12. Second, close the slag discharge port 8, open the water inlet 9 to fill the device with water, and then adjust the current value to make the surface of the cathode plate 12 undergo hydrogen evolution reaction. Then, stabilize the current value so that the device works under constant current. When the surface of the cathode plate 12 is full of scale, stop the DC constant current source, close the water inlet 9, and use ultrasonic waves to peel off the scale on the surface of the cathode plate 12 to regenerate the cathode. After the regeneration is completed, open the slag discharge port 8 to drain the loose scale in the device.

[0032] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
