Description

Technical Field

[0001] This utility model relates to the field of chlorination generator technology, and in particular to a brine chlorination generator for water purification. Background Technology

[0002] There are many ways to disinfect swimming pools, one of which is to use a salt chlorinator. The salt chlorinator mainly consists of a control box and a reaction component. The control box contains a circuit board, and the reaction component contains an electrode plate. The electrode plate is connected to the circuit board by wires. When the water in the pool enters the salt chlorinator, it comes into contact with the electrode plate and undergoes an electrolytic reaction, ultimately achieving sterilization and disinfection of the pool water.

[0003] Salt chlorinators generate chlorine gas by electrolyzing brine to periodically disinfect water bodies, but the following problems have been found in the use of existing salt chlorinator electrolysis plate devices:

[0004] Excessive levels of scale-forming ions such as calcium and magnesium in the water cause rapid deposition of calcium and magnesium precipitates on the electrodes during electrolysis, leading to a rapid increase in cell voltage, a quick decrease in current efficiency, and the need for frequent acid washing of the electrolytic cell. This accelerates the peeling off of the electrode coating and shortens the lifespan of the electrodes.

[0005] To reduce the calcium and magnesium ion content in hard and chlorinated water, softening treatment is required beforehand. Traditional softening processes typically use chemical dosing, mainly including "lime softening" and "two-stage softening with sodium hydroxide and sodium carbonate". However, chemical dosing softening processes have disadvantages such as high reagent costs, lengthy processes, large equipment footprint and maintenance workload, and complex operation. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problem that scale easily forms on the electrolytic plates in the prior art, which is difficult to handle, not only difficult to operate but also requires a large cost.

[0007] To address the aforementioned technical problems, this utility model provides a brine chlorination generator for water purification, comprising: an anode plate, a cathode plate, and a bipolar plate, which are stacked together; two cathode plates are provided, connected by a cathode conductive rod; one anode plate is provided, located in the middle between the two cathode plates, and connected by an anode conductive rod; multiple bipolar plates are provided between the anode plate and the cathode plates on both sides; isolation blocks are provided between the anode plate and the bipolar plates, between the bipolar plates, and between the cathode plate and the bipolar plates to achieve insulation between the anode plate, cathode plate, and bipolar plates; wherein, the anode plate and cathode plate are made of the same material, used to realize the reversal of the positive and negative electrodes connected to the anode plate and cathode plate. Salt chlorination generator technology is developing towards high efficiency, energy saving, safety, and intelligence. Structural innovation improves purification efficiency and reduces dependence on chemical chlorine disinfectants, lowering the risks of using and storing chemical substances. At the same time, the chlorine content produced by the salt chlorination generator is more stable and milder. The electrodes can be reversed, eliminating the need for acid washing. Widely used in hotels, private swimming pools, and guesthouses, this invention features a precious metal-coated electrode assembly inside the electrolytic cell, offering excellent stability and reduced power consumption. The electrodes can be reversed to reduce scaling, significantly extending service life, reducing labor costs, and preventing secondary pollution.

[0010] In one embodiment of this utility model, the isolation block is annular, and the stud portion of the bolt passes through the circular hole at the center of the isolation block.

[0011] In one embodiment of this utility model, the isolation block, bolt, and nut are all made of polytetrafluoroethylene.

[0012] In one embodiment of this utility model, the anode plate is a rectangular flat plate, and a first protrusion is provided on the side of the anode plate connected to the anode conductive rod. A first groove is provided on the first protrusion, and one end of the anode conductive rod is installed in the first groove.

[0013] In one embodiment of the present invention, a first mounting hole is provided at each of the four corners of the anode plate, and the first mounting hole is used for the stud portion of the bolt to pass through.

[0016] In one embodiment of this utility model, the bipolar plate is a rectangular flat plate, and a third mounting hole is provided at each of the four corners of the bipolar plate, the third mounting hole being for the stud portion of the bolt to pass through.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1-4As shown, the brine chlorination generator for water purification of this utility model includes: an anode plate 1, a cathode plate 2, and a bipolar plate 3, which are stacked together; two cathode plates 2 are provided, with a cathode conductive rod 4 connecting the two cathode plates 2; one anode plate 1 is provided, located in the middle between the two cathode plates 2, with an anode conductive rod 5 connected to the anode plate 1; multiple bipolar plates 3 are provided between the anode plate 1 and the cathode plates 2 on both sides; isolation blocks 10 are provided between the anode plate 1 and the bipolar plate 3, between the bipolar plates 3, and between the cathode plate 2 and the bipolar plate 3 to achieve insulation between the anode plate 1, the cathode plate 2, and the bipolar plate 3; wherein, the anode plate 1 and the cathode plate 2 are made of the same material, used to realize the reversal of the positive and negative electrodes connected to the anode plate 1 and the cathode plate 2. During normal use, anode plate 1 is connected to the positive electrode, and cathode plate 2 is connected to the negative electrode, allowing the chlorination generator to purify water normally. When the positive and negative electrodes connected to anode plate 1 and cathode plate 2 are interchanged, i.e., anode plate 1 is connected to the negative electrode and cathode plate 2 is connected to the positive electrode, descaling can be achieved on anode plate 1, cathode plate 2, and bipolar plate 3. To achieve descaling on anode plate 1 and cathode plate 2, bipolar plate 3 needs to be designed. Specifically, bipolar plate 3 is configured with anode and cathode on two sides, i.e., one rectangular side of bipolar plate 3 is set as the anode, and the other opposite rectangular side is set as the cathode. For example, if the side of the bipolar plate 3 adjacent to the anode plate 1 that faces the anode plate 1 is the cathode, then the side of the bipolar plate 3 that is far away from the anode plate 1 is set as the anode. If one side of the adjacent bipolar plate 3 is the anode, then the other side is the cathode. The arrangement of the cathode plate 2 and the bipolar plate 3 is similar. In this way, when the anode plate 1 and the cathode plate 2 are connected and reversed for descaling, the anode plate 1, the cathode plate 2 and the bipolar plate 3 are descaled through the liquid in the combination of the anode and cathode.

[0033] To enable the interchangeability of anode plate 1 and cathode plate 2, preferably, both anode plate 1 and cathode plate 2 are made of ruthenium-iridium-titanium.

[0034] The connection between the anode plate 1, cathode plate 2, and bipolar plate 3 is such that bolts 6 and nuts 7 are provided between them. The stud portion of the bolt 6 passes through the anode plate 1, cathode plate 2, and bipolar plate 3, and the bolt 6 is locked by the nut 7. The isolation block 10 is annular, and the stud portion of the bolt 6 passes through the circular hole in the center of the isolation block 10.

[0035] To achieve insulation, the insulating block 10, bolt 6, and nut 7 are all made of polytetrafluoroethylene.

[0036] Reference Figure 5 , 6As shown, the anode plate 1 is a rectangular flat plate. A first boss 11 is provided on the side of the anode plate 1 that connects to the anode conductive rod 5. A first groove 111 is provided on the first boss 11, and one end of the anode conductive rod 5 is installed in the first groove 111. A first mounting hole 12 is provided at each of the four corners of the anode plate 1, and the first mounting hole 12 is used for the stud portion of the bolt 6 to pass through.

[0037] Reference Figure 7 , 8 As shown, the cathode plate 2 is a rectangular flat plate. A second protrusion 21 is provided on the side of the cathode plate 2 connected to the cathode conductive rod 4. A second groove 211 is provided on the second protrusion 21. A connecting block 22 is provided between the two cathode plates 2. The end of the connecting block 22 is installed in the second groove 211, and the cathode conductive rod 4 is installed on the connecting block 22. A second mounting hole 23 is provided at each of the four corners of the cathode plate 2, through which the stud portion of the bolt 6 passes.

[0038] Reference Figure 9 As shown, the bipolar plate 3 is a rectangular flat plate, and each of the four corners of the bipolar plate 3 is provided with a third mounting hole 31, which is used for the stud portion of the bolt 6 to pass through.

[0039] Reference Figure 10 As shown, there is a mounting plate on the superimposed anode plate 1, cathode plate 2 and bipolar plate 3. It is tightened onto the tee pipe with a nut, which is convenient for installation. The cathode conductive rod 4 and anode conductive rod 5 extend out of the nut, and when not in use, the parts of the cathode conductive rod 4 and anode conductive rod 5 that extend out of the nut are covered with protective sleeves.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
