Description

Technical Field

[0001] The present invention relates to the technical field of electrolysis equipment, and particularly relates to a stable and high-performance electrolytic cell for producing acid-base water. Background Art

[0002] The production process of acid-base water is based on the principle of electrolyzed water. By using an ion exchange membrane or a microfiltration membrane to separate the flow channels into an anode flow channel and a cathode flow channel, the anode flow channel and the cathode flow channel are electrolyzed separately. Through the migration of ions during the electrolysis process, the concentrations of hydrogen ions and hydroxide ions in the two flow channels are changed, thereby producing acidic water or alkaline water.

[0003] Most of the existing electrolytic cells for producing acid-base water are multi-layer structures. This structure can greatly increase the production of acid-base water under the electrolysis of multiple electrodes and multiple flow channels, and is suitable for application in large-scale electrolysis equipment. However, the existing multi-layer structure has poor sealing performance, and it is easy to leak water and cross-flow, and the electrolysis performance of the electrolytic cell is unstable.

In the existing electrolytic cell, the sealing between the sheet-shaped connection piece and the electrolytic cells on both sides of the electrode plate, as well as between adjacent electrolytic cells, is achieved by passing through a large sealing ring with a small sealing ring (specifically, the sheet-shaped connection piece on the electrode plate passes through the small sealing ring, the outer surface of the small sealing ring abuts against the sheet-shaped connection piece, the cathode layer plate and the anode layer plate, and the large sealing ring is pressed between the cathode layer plate and the anode layer plate). This kind of sealing ring has a complex structure, great assembly difficulty, and low stability. The more the number of laminated layers, the greater the tightening force required to ensure sealing. Once the magnitude and application position of the tightening force change slightly, it is easy to leak water; in addition, since the sheet-shaped connection piece is connected to an external power source, the sheet-shaped connection piece will pull on the sealing ring, easily causing water leakage in multiple places. The third sealing ring of this embodiment bypasses the cathode terminal and the anode terminal and only abuts against the cathode layer plate and the anode layer plate, with high sealing reliability; the cathode terminal and the anode terminal are respectively sealed through the first sealing ring and the second sealing ring. The two separate sealing structures strengthen the overall sealing performance of the electrolytic cell, and without the complex overlapping sealing structure, the assembly process can be simplified, and the electrolytic cell with a large number of laminated layers will not increase the risk of water leakage, ensuring the stability and electrolysis performance of the electrolytic cell.

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] As Figure 1 and Figure 2 shown, the present invention provides a stable and high-performance electrolytic cell for producing acid-base water, including a cathode layer plate 1, a cathode electrode plate 2, an anode layer plate 3 and an anode electrode plate 4. The cathode layer plate 1 and the anode layer plate 3 are stacked and arranged alternately. Cathode electrolysis chambers 11, 31 and anode electrolysis chambers 12, 32 are stacked in both the cathode layer plate 1 and the anode layer plate 3, and an ion migration membrane 5 for separating the cathode electrolysis chambers 11, 31 and the anode electrolysis chambers 12, 32; the cathode electrode plate 2 is disposed between the cathode electrolysis chambers 11, 31 of the adjacent cathode layer plate 1 and anode layer plate 3; the anode electrode plate 4 is disposed between the anode electrolysis chambers 12, 32 of the adjacent anode layer plate 3 and cathode layer plate 1; the cathode layer plate 1 and the anode layer plate 3 are both provided with circulation holes 13, 33, and the cathode electrolysis chambers 11, 31 and the anode electrolysis chambers 12, 32 between the cathode layer plate 1 and the adjacent anode layer plate 3 are respectively communicated through the circulation holes 13, 33 to form a cathode water path and an anode water path; wherein, in combination with Figure 3 and Figure 4 , a first positioning hole 14 is provided on the cathode layer plate 1, a cathode connection post 21 extending outside the first positioning hole 14 is provided on the cathode electrode plate 2, and the cathode connection post 21 is sealed with the first positioning hole 14 through a first sealing ring (not shown in the figure); a second positioning hole 34 is provided on the anode layer plate 3, an anode connection post 41 extending outside the second positioning hole 34 is provided on the anode electrode plate 4, and the anode connection post 41 is sealed with the second positioning hole 34 through a second sealing ring (not shown in the figure); a third sealing ring c for sealing the cathode electrolysis chambers 11, 31 or the anode electrolysis chambers 12, 32 is provided between the adjacent anode layer plate 3 and cathode layer plate 1.

[0034] In this embodiment, by providing cathode electrolytic chambers 11, 31, anode electrolytic chambers 12, 32 and ion migration membranes 5 on the cathode laminar plate 1 and the anode laminar plate 3, the cathode electrode plate 2 is disposed between the cathode electrolytic chambers 11, 31 of the adjacent cathode laminar plate 1 and anode laminar plate 3, and the anode electrode plate 4 is disposed between the anode electrolytic chambers 12, 32 of the adjacent anode laminar plate 3 and cathode laminar plate 1. The cathode electrolytic chambers 11, 31 are communicated through the flow holes 13, 33 on the cathode laminar plate 1 and the anode laminar plate 3 to form a cathode water path, and the anode electrolytic chambers 12, 32 are communicated through the flow holes 13, 33 on the cathode laminar plate 1 and the anode laminar plate 3 to form an anode water path. The cathode water path and the anode water path are separated from each other. By laminating and staggering the cathode laminar plate 1 and the anode laminar plate 3 into multiple layers, the cathode water path and the anode water path are electrolyzed multiple times, improving the electrolysis efficiency. In addition, by providing a first positioning hole 14 and a second positioning hole 34 on the cathode laminar plate 1 and the anode laminar plate 3 respectively, a cathode terminal 21 is provided on the cathode electrode plate 2, and an anode terminal 41 is provided on the anode electrode plate 4. The seal between the cathode terminal 21 and the cathode laminar plate 1 is achieved through a first sealing ring, the seal between the anode terminal 41 and the anode laminar plate 3 is achieved through a second sealing ring, and the seal of the cathode electrolytic chambers 11, 31 or the anode electrolytic chambers 12, 32 between the cathode laminar plate 1 and the anode laminar plate 3 is achieved through a third sealing ring c; the independent sealing structures do not affect each other, strengthening the overall sealing performance of the electrolytic cell. In the existing electrolytic cell, the seal between the sheet-shaped connection piece and the electrolytic cell on both sides of the electrode plate, as well as between adjacent electrolytic cells, is achieved by passing through a large sealing ring with a small sealing ring (specifically, the sheet-shaped connection piece on the electrode plate passes through the small sealing ring, the outer surface of the small sealing ring abuts against the sheet-shaped connection piece, the cathode laminar plate 1 and the anode laminar plate 3, and the large sealing ring is pressed between the cathode laminar plate 1 and the anode laminar plate 3). This kind of sealing ring has a complex structure, difficult assembly, and low stability. The more the number of laminated layers, the sufficient tightening force is required to ensure the seal. Once the magnitude and application position of the tightening force change slightly, it is easy to leak water; in addition, since the sheet-shaped connection piece is connected to an external power source, the sheet-shaped connection piece will pull the sealing ring, easily causing water leakage in multiple places. The third sealing ring c of this embodiment bypasses the cathode terminal 21 and the anode terminal 41 and only abuts against the cathode laminar plate 1 and the anode laminar plate 3, with high sealing reliability; the cathode terminal 21 and the anode terminal 41 are respectively sealed through the first sealing ring and the second sealing ring. The two separate sealing structures strengthen the overall sealing performance of the electrolytic cell, and there is no complex overlapping sealing structure, which can simplify the assembly process. The electrolytic cell with a large number of laminated layers will not increase the risk of water leakage, ensuring the stability and electrolysis performance of the electrolytic cell.

[0035] Specifically, a first clamping protrusion 15 is provided on the cathode layer board 1 of this embodiment, and the first positioning hole 14 is arranged on the first clamping protrusion 15; a second clamping protrusion 35 is provided on the anode layer board 3, and the second positioning hole 34 is arranged on the second clamping protrusion 35; a first clamping groove 16 adapted to the second clamping protrusion 35 is provided on the cathode layer board 1, and a second clamping groove 36 adapted to the first clamping protrusion 15 is provided on the anode layer board 3.

[0036] By providing the second clamping groove 36 corresponding to the first clamping protrusion 15 on the anode layer board 3 and the first clamping groove 16 corresponding to the second clamping protrusion 35 on the cathode layer board 1, when the cathode layer board 1 and the anode layer board 3 are assembled in a stacked and staggered manner, this complementary assembly structure has a good positioning effect, and the assembly structure is unique, which can ensure the staggered stacking and assembly of the cathode layer board 1 and the anode layer board 3, and improve the assembly efficiency.

[0037] In this embodiment, the third sealing ring c is clamped between the first clamping protrusion 15 and the second clamping groove 36, or between the second clamping protrusion 35 and the first clamping groove 16. At this time, the third sealing ring c is in closer contact with the cathode layer board 1 and the anode layer board 3, and the sealing effect is better.

[0038] Both the first sealing ring and the second sealing ring in this embodiment are O-shaped sealing rings. The third sealing ring c includes a main sealing ring c1 for sealing the cathode electrolytic chambers 11, 31 and the anode electrolytic chambers 12, 32, and a flow hole sealing ring c2 for sealing the flow holes 13, 33. The main sealing ring c1 and the flow hole sealing ring c2 are integrally formed. The area of the main sealing ring c1 is larger than the area of the anode electrolytic chambers 12, 32 or the cathode electrolytic chambers 11, 31. The O-shaped sealing ring and the third sealing ring c are made of silica gel.

[0039] To further improve the sealing effect and avoid water leakage and seepage, in this embodiment, it is preferably to injection-mold the cathode layer board 1 and the anode layer board 3 on the ion migration membrane 5. During the injection molding process of the cathode layer board 1 and the anode layer board 3, the ion migration membrane 5 is embedded in the cathode layer board 1 and the anode layer board 3. The ion migration membrane 5 and the cathode layer board 1 or the anode layer board 3 become an integral body, and the cathode electrolytic chambers 11, 31 and the anode electrolytic chambers 12, 32 on the cathode layer board 1 or the anode layer board 3 are separated. This connection form can avoid leakage between the cathode electrolytic chambers 11, 31 and the anode electrolytic chambers 12, 32, improve the electrolysis stability, and ensure a good electrolysis effect.

[0040] Since the cathode layer plate 1 and the anode layer plate 3 are injection-molded on the ion migration membrane 5, the ion migration membrane 5 in the cathode layer plate 1 and the anode layer plate 3 of this embodiment can be selected to be one or both of an ion membrane or a microfiltration membrane as needed. Since the microfiltration membrane can pass both anions and cations, while the ion membrane can only selectively pass cations or anions, when electrolysis is carried out using the microfiltration membrane and the ion membrane respectively, the ion migration effects in the two electrolyses are different. Generally speaking, the pH value of the acidic water electrolyzed through the ion membrane is lower, and the pH value of the alkaline water is higher.

[0041] In the existing electrolytic cell, an ion membrane or a microfiltration membrane cannot be applied in the same electrolytic cell because the materials of the microfiltration membrane and the ion membrane are different. On the premise of ensuring the sealing effect between the cathode electrolysis chambers 11, 31 and the anode electrolysis chambers 12, 32, the microfiltration membrane can directly separate the flow channels by ultrasonic welding on plastic parts, while the ion membrane cannot be ultrasonically welded and requires a sealing ring between the plates to be pressed tightly to separate the flow channels, resulting in the structures of the cathode layer plate 1 and the anode layer plate 3 provided with these two ion migration membranes 5 not being unified. Therefore, only a single type of ion migration membrane 5 can be applied in the same electrolytic cell.

[0042] In this embodiment, the microfiltration membrane or the ion membrane is integrated with the cathode layer plate 1 or the anode layer plate 3 into a module through the pre-embedding process in injection molding. During the injection molding process, the microfiltration membrane or the ion membrane is embedded in the cathode layer plate 1 or the anode layer plate 3. This structure can separate the cathode electrolysis chambers 11, 31 and the anode electrolysis chambers 12, 32 without considering the sealing effect between the ion migration membrane 5 and the cathode layer plate 1 or the anode layer plate 3. The two are injection-molded into one body, with a firm structure and no leakage, ensuring a good electrolysis effect. In addition, the injection-molded microfiltration membrane and ion membrane can be applied in the same electrolytic cell, and the electrolytic cell can obtain a wider pH range of the electrolytic solution. It goes without saying that since the ion migration membrane 5 is integrated with the cathode layer plate 1 or the anode layer plate 3 into a module, it can reduce the processing and assembly process flow, eliminate the complexity of assembly, and reduce the processing cost.

[0043] Combined Figure 5 and Figure 6 This embodiment of the stable and high-performance electrolytic cell for producing acidic and alkaline water further includes a top pressing plate 6 and a bottom pressing plate 7. The top pressing plate 6 and the bottom pressing plate 7 stack and press the cathode layer plate 1, the cathode electrode plate 2, the anode layer plate 3, and the anode electrode plate 4. Among them, the bottom pressing plate 7 is provided with a cathode water inlet 71 and an anode water inlet 72, the top pressing plate 6 is provided with a cathode water outlet 61 and an anode water outlet 62, the cathode water inlet 71 and the cathode water outlet 61 communicate with the cathode electrolysis chambers 11, 31 through the through holes 13, 33, and the anode water inlet 72 and the anode water outlet 62 communicate with the anode electrolysis chambers 12, 32 through the through holes 13, 33.

[0044] The bottom pressing plate 7 is provided with a third clamping protrusion 73 adapted to the second clamping groove 36 on the anode layer plate 3. The cathode electrode plate 2 is provided on one side of the bottom pressing plate 7 that abuts against the anode layer plate 3. The bottom pressing plate 7 is sealed with the anode layer plate 3 through the third sealing ring c. The top pressing plate 6 is provided with a third clamping groove 63 adapted to the first clamping protrusion 15 on the cathode layer plate 1. The top pressing plate 6 is sealed with the cathode layer plate 1 through the third sealing ring c.

[0045] To facilitate the energization of the cathode electrode plate 2 and the anode electrode plate 4, the stable and high-performance electrolytic cell for producing acid-base water further includes a cathode connecting piece 8 and an anode connecting piece 9. The cathode connecting piece 8 is connected in parallel with the cathode terminal 21, and the anode connecting piece 9 is connected in parallel with the anode terminal 41.

[0046] In summary, implementing the present invention has the following beneficial effects:

[0047] 1. The third sealing ring c bypasses the cathode terminal 21 and the anode terminal 41 and only abuts against the cathode layer plate 1 and the anode layer plate 3, with high sealing reliability; while the cathode terminal 21 and the anode terminal 41 are respectively sealed through the first sealing ring and the second sealing ring, and the two separate sealing structures strengthen the overall sealing of the electrolytic cell; electrolytic cells with a large number of stacked layers will not increase the risk of water leakage, ensuring the stability and electrolytic performance of the electrolytic cell.

[0048] 2. The ion migration membrane 5 is injection-molded integrally with the cathode layer plate 1 or the anode layer plate 3, avoiding leakage between the cathode electrolytic chamber 11, 31 and the anode electrolytic chamber 12, 32, improving electrolytic stability and ensuring good electrolytic effects.

[0049] 3. The ion migration membrane 5 is injection-molded integrally with the cathode layer plate 1 or the anode layer plate 3, which can reduce the processing and assembly process flow and lower the processing cost.

[0050] 4. The microfiltration membrane and the ion membrane can be applied in the same electrolytic cell, and the electrolytic cell can obtain a wider pH range of the electrolytic solution.

[0051] 5. The complementary assembly structure of the anode layer plate 3 and the cathode layer plate 1 has a good positioning effect, and the assembly structure is unique, which can ensure the staggered laminated assembly of the cathode layer plate 1 and the anode layer plate 3 and improve the assembly efficiency.

[0052] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
