[0051] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0052] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0053] Example 1, such as Figures 1 to 4 As shown, an electrolysis device includes a frame 1, on which an electrolytic cell 2 is mounted. The upper part of the electrolytic cell 2 is connected to the input end of a buffer tank 9, and the output end of the buffer tank 9 is connected to the input end of a circulating pump 7. The output end of the circulating pump 7 is connected to the lower part of the electrolytic cell 2. In use, firstly, the slurry to be electrolyzed is added to the buffer tank 9 through the inlet. Then, the circulating pump 7 is started, and the slurry is injected into the electrolytic cell 2 from the bottom. The liquid level slowly rises, passes through the cathode chamber, and when it reaches the outlet height, it is discharged from the outlet and flows back to the buffer tank 9. The slurry circulates under the action of the circulating pump 7. When connected to a DC power supply, the circulating slurry is electrolyzed, achieving continuous circulating electrolysis. This technical solution is suitable for situations where the slurry to be electrolyzed is prone to sedimentation, such as in wastewater treatment. Because it is circulating, the slurry to be electrolyzed is less likely to settle, allowing for a longer electrolysis reaction and a more thorough reaction.
[0054] Specifically, several fifth circulation return pipes 13 are connected to the upper parts of the left and right sides of the electrolytic cell 2. These fifth circulation return pipes 13 on each side are connected to a fourth circulation return pipe 12. The fourth circulation return pipes 12 on both the left and right sides are connected to a third circulation return pipe 11. The third circulation return pipe 11 is connected to the input end of the buffer tank 9. A second circulation return pipe 8 connects the buffer tank 9 to the circulation pump 7, and a first circulation return pipe 6 connects the circulation pump 7 to the buffer tank 9. In use, firstly, the slurry to be electrolyzed is added to the buffer tank 9 through the feed inlet. The circulation pump 7 is then started. The slurry is injected into the electrolytic cell 2 from the bottom through the second circulation return pipe 8 and the first circulation return pipe 6. The liquid level slowly rises, passes through the cathode chamber, and reaches the outlet height, where it is discharged. The slurry then flows back to the buffer tank 9 through the fifth circulation return pipe 13, the fourth circulation return pipe 12, and the third circulation return pipe 11. The fifth circulation return pipe 13 extends in the left and right directions, and the fourth circulation return pipe 12 extends in the front and back directions. This pipeline arrangement facilitates slurry circulation.
[0055] Specifically, a hopper 4 is installed at the lower end of the electrolytic cell 2, and the output end of the circulating pump 7 is connected to the lower side of the hopper 4. The lower end of the hopper 4 has a discharge port 5. During use, the slurry is injected into the electrolytic cell 2 from the bottom. After electrolysis is completed, the discharge port 5 is opened for discharge, facilitating use. A cell cover 3 is installed at the upper part of the electrolytic cell 2, and a buffer tank 9 has a buffer tank inlet 10 at its lower part. During use, slurry can be fed through the buffer tank inlet 10 for convenience. The buffer tank 9 also has a buffer tank discharge port 19 at its lower part. During use, the slurry in the buffer tank 9 can be discharged through the buffer tank discharge port 19 for convenience.

The anode plates 1504 are connected to anode connecting wires 17, and the cathode plates 1603 are connected to cathode connecting wires 18. The anode connecting wires 17 and cathode connecting wires 18 are located at the top of the electrolytic cell 2, or alternatively on the side. Preferably, they can be arranged in an anode-cathode-anode sequence, or in a cathode-anode-cathode sequence. In use, the anode connecting wire 17 is connected to the positive terminal of the power supply, and the cathode connecting wire 18 is connected to the negative terminal. The anode plates 1504 and cathode plates 1603 cooperate to electrolyze the slurry.
[0057] Specifically, the electrolytic cell 2 is equipped with several anode boxes 15 and cathode boxes 16 arranged at intervals. Each anode box 15 includes two anode box side frames 1501, with an anode plate 1504 located between the two anode box side frames 1501. An anode box bottom frame 1502 is installed between the lower ends of the two anode box side frames 1501. Each cathode box 16 includes two cathode box side frames 1601, with a cathode plate 1603 located between the two cathode box side frames 1601. A cathode box bottom frame 1602 is installed between the lower ends of the two cathode box side frames 1601. This structure facilitates the installation and use of the anode plate 1504 and the cathode plate 1603. Between the two anode box side frames 1501, two diaphragm bottom frames 1505 are installed on both sides of the anode plate 1504. A diaphragm pressure frame 1506 is installed on the side of the diaphragm bottom frame 1505 away from the anode plate 1504. A diaphragm 1503 is installed between the diaphragm bottom frame 1505 and the diaphragm pressure frame 1506. The anode box 15 contains anolyte. In this structure, the diaphragm 1503 is divided into a cation separator and an anion separator, which are used to block the passage of anions and cations respectively, and selectively allow cations and anions to pass through, thereby improving electrolysis efficiency.
[0058] Specifically, side anode boxes 14 or side cathode boxes are arranged on both sides of the electrolytic cell 2. Each side anode box 14 includes two side anode box frames 1401, with a side anode plate 1404 installed between the two side anode box frames 1401, and a side anode box bottom frame 1402 installed between the lower ends of the two side anode box frames 1401. Preferably, if arranged in an anode-cathode-anode sequence, side anode boxes 14 are arranged on both sides of the electrolytic cell 2; if arranged in a cathode-anode-cathode sequence, side cathode boxes are arranged on both sides of the electrolytic cell 2. The structure of the side cathode boxes is the same as that of the cathode boxes 16. This structure facilitates the arrangement of the anode plate 1504 and the cathode plate 1603. A side limiting plate 1407 is installed between the two side anode box side frames 1401, located on the side of the side anode plate 1404 near the side wall of the electrolytic cell 2. A side diaphragm bottom frame 1405 is also installed between the two side anode box side frames 1401, located on the side of the side anode plate 1404 away from the side wall of the electrolytic cell 2. A side diaphragm pressure frame 1406 is installed on the side of the side diaphragm bottom frame 1405 away from the side anode plate 1404. A side diaphragm 1403 is installed between the side diaphragm bottom frame 1405 and the side diaphragm pressure frame 1406. The side anode box 14 contains anolyte. This structure facilitates the installation and use of the side anode plate 1404.
[0059] Example 2, as Figure 15 As shown, there are multiple electrolytic cells 2, with their input and output ends connected end-to-end. These multiple electrolytic cells 2 are arranged in a stepped series from high to low. The slurry to be electrolyzed exits from the first electrolytic cell 2 and enters the second, then the third, and so on. By extending the electrolysis time and using a sufficient number of electrolytic cells 2, the electrolysis targets can be achieved in one pass without slurry circulation, thus improving efficiency.
[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
