[0034] Implementing this invention has the following beneficial effects:

[0035] This invention discloses an electrolysis device, including an electrolytic cell and an electrolysis assembly for water electrolysis. The electrolysis assembly includes a cathode plate and an anode plate. The electrolytic cell contains a first electrolysis chamber and a second electrolysis chamber, both of which house the electrolysis assembly. The first electrolysis chamber also contains an ion exchange membrane disposed between the cathode and anode plates. The first electrolysis chamber has a cathode flow layer and an anode flow layer to separately accommodate the cathode and anode plates, respectively, and adjacent cathode and anode flow layers are separated by the ion exchange membrane. Therefore, water flowing through the cathode and anode flow layers can be electrolyzed by the cathode and anode plates, respectively, resulting in acidic and alkaline water. Thus, by using multiple layers of the cathode and anode flow layers, the production efficiency of slightly acidic water can be improved.

[0036] On the other hand, the electrolytic cell body includes multiple longitudinally stacked frame bodies; each stacked frame body is provided with a first cavity opening and a second cavity opening, so that after the multiple stacked frame bodies are stacked, they are respectively stacked to form the first electrolytic cavity and the second electrolytic cavity.

This design allows the manufacturer to freely assemble according to needs, which is highly flexible. On the other hand, when internal cleaning or replacement is required, it can be disassembled, so that any internal space can be easily cleaned. At the same time, when any electrolytic component is damaged, it can be conveniently replaced individually.

[0037] In order to maintain the weak acidity of the electrolyzed water, the electrolytic cell is provided with an alkaline drainage channel, a cathode inlet and an anode inlet. The cathode inlet, each cathode flow layer and the alkaline drainage channel flow in sequence to discharge alkaline water that affects the production of slightly acidic water.

[0045] 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.

[0046] See Figure 1-4 This invention provides an electrolysis device, including an electrolysis tank 1 and an electrolysis assembly for electrolyzing water, wherein the electrolysis assembly includes a cathode plate 2a and an anode plate 2b;

[0047] The electrolytic cell 1 comprises multiple longitudinally stacked frame bodies 11 and a cell cover 12 for closing the stacked frame bodies 11. The stacked frame bodies 11 are sandwiched between two cell covers 12, so that the first electrolytic cavity 1a and the second electrolytic cavity 1b form a closed space. The stacked frame bodies 11 are provided with a first cavity opening 111 and a second cavity opening 112, so that after the multiple stacked frame bodies 11 are stacked, they are respectively stacked to form the first electrolytic cavity 1a and the second electrolytic cavity 1b. Conductive posts 5 are provided on both sides of the stacked frame bodies 11 for electrical connection with the cathode plate or anode plate.

[0048] The electrolytic cell 1 is provided with a first electrolytic chamber 1a and a second electrolytic chamber 1b. Both the first electrolytic chamber 1a and the second electrolytic chamber 1b are provided with the electrolytic components. The first electrolytic chamber 1a is also provided with an ion membrane 3, which is disposed between the cathode plate 2a and the anode plate 2b.

[0049] The first electrolysis chamber 1a is provided with a cathode flow layer 4a and an anode flow layer 4b to separately accommodate the cathode plate 2a and the anode plate 2b, and adjacent cathode flow layers 4a and anode flow layers 4b are separated by the ion membrane 3. The above design can easily form a structure with multiple cathode flow layers 4a and anode flow layers 4b, and is also convenient for production.

[0050] The electrolytic cell 1 is provided with an alkaline drainage channel 1c, a cathode inlet 1d and an anode inlet 1e, and the cathode inlet 1d, each of the cathode flow layers 4a and the alkaline drainage channel 1c flow in sequence;

[0051] Each of the anode flow layers 4b is connected to the second electrolysis chamber 1b, and the electrolysis tank 1 is provided with a micro-acid drainage channel 1f connected to the second electrolysis chamber 1b.

[0052] The anode inlet 1e, each of the anode flow layers 4b, the second electrolysis chamber 1b, and the micro-acid drainage channel 1f flow sequentially.

[0053] Specifically, at least two electrolysis units are provided, and the cathode flow layer 4a and anode flow layer 4b are configured in corresponding numbers according to the number of electrolysis units. Therefore, the required number of electrolysis units can be preset according to the actual production efficiency requirements.

[0054] See Figure 5 The ion membrane 3 is disposed at the first cavity opening 111 of the stacked frame 11 to close the first cavity opening 111; and by providing the ion membrane 3, the stacked frame 11 is divided into an upper stacked portion 11A and a lower stacked portion 11b.

[0055] In two adjacent stacked frames 11, the cathode flow layer 4a or the anode flow layer 4b is formed between the lower stack 11b of one stacked frame 11 and the upper stack 11a of the other stacked frame 11. Therefore, due to the arrangement of the ion membrane 3, after the stacking of multiple stacked frames 11, multiple individually flowing cathode flow layers 4a and anode flow layers 4b can be formed, and they are arranged alternately in sequence.

[0056] Furthermore, in order to improve the electrolysis effect of the first electrolysis chamber 1a and the second electrolysis chamber 1b, multiple partition strips 113 for forming a serpentine flow channel are provided at the first chamber opening 111 and the second chamber opening 112 on the stacked frame 11. Specifically, each end of the partition strip 113 is provided with a water passage opening 1131 for water to flow through, and the water passage openings 1131 at both ends are located at the upper stacked part 11a and the lower stacked part 11b, respectively, so that the cathode flow layer 4a or the anode flow layer 4b forms a serpentine flow channel, thereby extending the travel distance of the water flowing through the first electrolysis chamber 1a and the second electrolysis chamber 1b, and thus extending the electrolysis time.

[0057] The electrolytic cell 1 is provided with a cathode water collection channel 13 and an anode water collection channel 14. The cathode inlet 1d is connected in parallel with each of the cathode flow layers 4a through the cathode water collection channel 13; the anode inlet 1e is connected in parallel with each of the anode flow layers 4b through the anode water collection channel 14. With this configuration, the user can introduce a specific electrolyte formula into the cathode flow layer 4a and / or the anode flow layer 4b respectively according to the required production requirements for slightly acidic water, thereby achieving the effect of independent electrolysis of the electrolyte.

[0058] In the structural design to achieve independent flow and water supply between the cathode flow layer 4a and the anode flow layer 4b, a water collection flow section 15 and a water distribution flow section 16 are respectively provided on both sides of the first cavity opening 111.

[0059] The water collection and flow section 15 has two water collection holes 17, which are used to form the cathode water collection channel 13 and the anode water collection channel 14 respectively; the water distribution and flow section 16 has alkaline drainage holes 161 for forming the alkaline drainage channel 1c.

[0060] Meanwhile, in order to avoid interference between the feed water of the cathode flow layer 4a and the anode flow layer 4b, the upper and lower end faces of the water collection and flow section 15 are respectively provided with side passage grooves 18, which are located in the upper stack 11a and the lower stack 11b respectively, so as to connect the cathode flow layer 4a and the anode flow layer 4b respectively.

[0061] On the water collection and flow section 15 of the same stacked frame 11, the side passage grooves 18 of the upper stacked section 11a and the lower stacked section 11b are staggered, and the upper stacked section 11a and the lower stacked section 11b are respectively provided with water collection holes 17; the water collection hole 17 of the upper stacked section 11a is connected to the side passage groove 18 of the lower stacked section 11b, and the water collection hole 17 of the lower stacked section 11b is connected to the side passage groove 18 of the upper stacked section 11a.

[0062] Furthermore, for ease of description, depending on the different structures of the water collection and circulation section 15, the stacked frame 11 is divided into an upper frame 11A and a lower frame 11B, and the upper frame 11A and the lower frame 11B are stacked alternately in sequence.

[0063] In the two adjacent stacked frames 11, the side through groove 18 of the upper frame 11A and the side through groove 18 of the lower frame 11B are arranged in a mirror symmetrical manner; between the adjacent stacked frames 11, the end faces of the water collection and flow section 15 are correspondingly attached to each other to restrict the water flow from flowing out between the end faces of the two adjacent water collection and flow sections 15.

[0064] With this configuration, as the upper frame 11A and the lower frame 11B are alternately stacked, the two water collection holes 17 of the water collection and circulation section 15 will be stacked to form the cathode water collection channel 13 and the anode water collection channel 14, which are not interconnected. At the same time, each is provided with a side passage groove 18 so that the water flows into the cathode circulation layer 4a or the anode circulation layer 4b independently.

[0065] More specifically, on the upper frame 11A, the upper and lower end faces of the water distribution flow section 16 are respectively provided with side passage grooves 18, which are located in the upper stack 11a and the lower stack 11b respectively, so as to connect the cathode flow layer 4a and the anode flow layer 4b respectively.

[0066] On the water distribution and flow section 16 of the same stacked frame 11, the side channels 18 provided by the upper stacked section 11a and the lower stacked section 11b are staggered. The alkaline drainage hole 161 is provided on the upper stacked section 11a and is correspondingly connected to the side channel 18 of the lower stacked section 11b.

[0067] On the water distribution and flow section 16 of the lower frame 11B, the upper stack 11a is provided with a side channel 18 communicating with the cathode flow layer 4a, and correspondingly communicating with the alkaline drainage hole 161 of the lower stack 11b of the adjacent upper frame 11A. The alkaline drainage hole 161 of the lower frame 11B is located at the lower stack 11b of the water distribution and flow section 16, and communicates with the side channel 18 of the upper stack 11a. At the same time, the lower stack 11b is provided with a communication notch 11c to form a communication channel between the anode flow layer 4b and the second cavity. See [reference needed]. Figure 6 .

[0068] Therefore, with the alternating stacking of the upper frame 11A and the lower frame 11B, the alkaline drainage holes 161 will overlap to form the alkaline drainage channel 1c, thereby diverting and discharging the electrolyzed water from each of the cathode flow layers 4a. Correspondingly, the electrolyzed water from each of the anode flow layers 4b will flow into the second electrolysis chamber 1b through the connecting gap 11c to perform secondary electrolysis on the slightly acidic electrolyzed water.

[0069] A micro-acid drainage section 19 is provided on one side of the second cavity opening 112. The upper and lower end faces of the micro-acid drainage section 19 are provided with micro-acid side grooves 191 for communicating with the second electrolysis cavity 1b and micro-acid holes 192 for overlapping to form the micro-acid drainage channel 1f. The micro-acid holes 192 are correspondingly located at the micro-acid side grooves 191 to communicate with them. Therefore, the electrolyzed water in the second electrolysis cavity 1b can flow into the micro-acid drainage channel 1f through the micro-acid side grooves 191.

[0070] Since the stacked frame 11 is sandwiched between the two tank covers 12, the cathode inlet 1d and the anode inlet 1e are located on the upper tank cover 12, and the lower tank cover 12 is provided with a micro-acid outlet 121 for discharging micro-acidic water, which connects to the micro-acid drainage channel 1f. Correspondingly, the lower tank cover 12 is provided with an alkaline drainage outlet 122 connected to the alkaline drainage channel 1c. This height difference facilitates liquid flow and reduces residual liquid in the first electrolysis chamber 1a and the second electrolysis chamber 1b when operation is stopped.

[0071] To facilitate the electrical connection between the external power electrode and the cathode plate 2a and the anode plate 2b, the stacked frame 11 is provided with power-through holes 110 on both sides for installing the conductive post 5. The power-through holes 110 on both sides are respectively used to communicate with the cathode flow layer 4a and the anode flow layer 4b so that the conductive post can be inserted from the outside.

[0072] In detail, each of the adjacent stacked frames 11 is provided with a positioning part 5a for mutual insertion and positioning and a recessed part 5b adapted to the positioning part. The power-conducting hole 110 is opened at the positioning part 5a and the recessed part 5b. Therefore, the adjacent stacked frames can be staggered between each other by the staggered insertion between the positioning part 5a and the recessed part 5b, so as to maintain the longitudinal stacking state.

[0073] One end of the conductive post 5 is provided with a snap-fit ​​groove 5c for the cathode or anode plate to be snapped into, so as to make contact and electrical connection with the cathode or anode plate. Therefore, the above arrangement can facilitate the parallel electrical connection of multiple cathode plates 2a or anode plates 2b by a single conductive strip 6.

[0074] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
