DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] Direct electrolysis equipment, such as Figure 1-Figure 5 As shown, it includes an electrolytic cell 1, an anode conductive plate 2, an anode conductive connector, a cathode conductive plate 3, a cathode conductive connector, an anode plate 4, a cathode plate 5, a partition 6, a placement box 7, a bottom plate 8, a limit block 9 and a fixing plate 11. The front side of the electrolytic cell 1 is provided with an anode conductive plate 2, and the anode conductive plate 2 is connected to the positive pole of the power supply. The rear side of the electrolytic cell 1 is provided with a cathode conductive plate 3, and the cathode conductive plate 3 is connected to the negative pole of the power supply. The bottom of the anode conductive plate 2 and the cathode conductive plate 3 is connected to the bottom of the bottom plate 8, and a plurality of through holes are opened on the bottom plate 8. The electrolytic cell 1 is provided with an anode plate 4 and a cathode plate 5, and the anode plate 4 and the cathode plate 5 are parallel to each other. Arranged in the electrolytic cell 1, each set of cathode plates 5 and anode plates 4 constitutes a circuit loop. Two adjacent sets of cathode plates 5 and anode plates 4, the cathode plates 5 or anode plates 4 in one set and the anode plates 4 or cathode plates 5 in the other set can also form a circuit loop, so that each side of the anode plate 4 can regenerate the etching solution and each side of the cathode plate 5 can have heavy metal precipitation. The cathode plate 5 is provided with a cathode conductive connector, and the anode plate 4 is provided with an anode conductive connector. The cathode plate 5 is connected to the cathode conductive plate 3 through the cathode conductive connector, and the anode plate 4 is connected to the anode conductive plate 2 through the anode conductive connector. The anode conductive joint is welded to the anode conductive plate 2 to reduce the film resistance between the anode conductive joint and the anode conductive plate 2. The cathode plate 5 is perpendicular to the cathode conductive plate 3, and the cathode conductive joint is parallel to the cathode conductive plate 3. The anode plate 4 is perpendicular to the anode conductive plate 2, and the anode conductive joint is parallel to the anode conductive plate 2. The cathode conductive joint is provided on the upper part of the cathode plate 5, and the cathode conductive joint extends from the top of the electrolytic cell 1 to connect with the cathode conductive plate 3 outside the electrolytic cell 1; the anode conductive joint is provided on the upper part of the anode plate 4, and the anode conductive joint extends from the top of the electrolytic cell 1 to connect with the anode conductive plate 2 outside the electrolytic cell 1. The cathode conductive connector and the anode conductive connector can be connected to the cathode plate 5 and the anode plate 4 respectively without affecting the volume of the electrolytic cell 1. A plurality of fixed plates 11 are provided on the anode conductive plate 2 and the cathode conductive plate 3. A limit block 9 is connected between every two fixed plates 11. The limit block 9 is used to support the cathode plate 5 or the anode plate 4. A placement box 7 is slidably connected to the front side of the electrolytic cell 1. The placement box 7 passes through the electrolytic cell 1. A plurality of through holes are opened on the upper front side of the electrolytic cell 1. The through holes are used to connect the exhaust valve. A plurality of front-to-back symmetrical circular holes are opened on the lower front and rear sides of the electrolytic cell 1. The circular holes are used to connect the electrolyte circulation pipe.

[0024] like Figure 3 As shown, an electromagnetic plate 10 is also included. The fixed plate 11 on the cathode conductive plate 3 can be replaced with the electromagnetic plate 10. The cathode conductive plate 3 is connected to the negative pole of the power supply. When power is turned on, the electromagnetic plate 10 will acquire magnetism. When the cathode plate 5 needs to be replaced, the cathode conductive plate 3 is disconnected from the negative pole of the power supply, the electromagnetic plate 10 loses power, and the electromagnetic force disappears, making it convenient to disassemble and replace the cathode plate 5.

[0025] like Figure 6 As shown, a positioning plate 12 is also included. A plurality of grooves are formed on the positioning plate 12 to provide additional mechanical support, enhance the overall structural strength, and be used to fix components such as the cover and make them more stable.

[0026] like Figure 2 As shown, it also includes a partition 6 and a support seat 801. The partition 6 is slidably connected to the electrolytic cell 1 so that the device can simultaneously process different types of electrolytes or perform different electrolysis processes, thereby improving the versatility and flexibility of the equipment. Several support seats 801 are provided on the top of the bottom plate 8, and the support seats 801 are used to support the electrolyte circulation pipe.

[0027] The anode plate 4 and the cathode plate 5 are arranged in parallel between the fixed plates 11 in the electrolytic cell 1. Etching waste liquid is added to the electrolytic cell 1 through the sliding placement box 7. After the power is turned on, the current passes through the circuit loop between the anode plate 4 and the cathode plate 5, and the electrolysis process begins. An oxidation reaction occurs on the anode plate 4, and the metal ions in the etching waste liquid lose electrons and enter the solution. A reduction reaction occurs on the cathode plate 5, and the heavy metal ions (such as copper, nickel, etc.) in the solution gain electrons and precipitate on the cathode surface, realizing heavy metal recovery. The gas generated during the electrolysis process is discharged through the exhaust valve on the upper front side of the electrolytic cell 1.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
