Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 3 This is the first embodiment of the present invention, which provides an acidic etching solution waste electrolytic cell, comprising:

[0030] A sealed top cover 2 is provided with an exhaust control assembly 4 in the middle position of the sealed top cover 2. The exhaust control assembly 4 includes a control main pipe 401 fixedly installed in the middle position of the sealed top cover 2. An air guide assembly 5 is provided on the outside of the control main pipe 401.

[0031] The air guiding assembly 5 includes a connecting manifold 501 fixedly connected to the left and right sides of the bottom end of the control main pipe 401. A connecting pipe 502 is fixedly connected to the bottom end of the connecting manifold 501. An air collecting pipe 504 is detachably installed at the bottom end of the connecting pipe 502. A connecting sleeve 503 is connected between the air collecting pipe 504 and the connecting pipe 502. Multiple air guiding heads 505 are fixedly connected to the bottom side wall of the air collecting pipe 504 at equal intervals.

[0032] Specifically, a tank body 1 is detachably installed at the bottom of the sealed top cover 2. A waste liquid flow component 3 is provided on one side wall of the tank body 1. An anode plate 7 corresponding to the gas collection pipe 504 is detachably installed inside the tank body 1. A cathode plate 8 is provided on one side of the anode plate 7.

[0033] Furthermore, the control manifold 401 is interconnected with the gas guide head 505 through the connecting manifold 501, connecting pipe 502, gas collecting pipe 504, etc., so that the gas inside the device can be discharged through the gas guide assembly 5, thereby improving the gas discharge effect of the device.

[0034] In use, when it is necessary to export the chlorine gas generated by the anode plate 7 during electrolysis, the exhaust control component 4 is activated. The control main pipe 401 of the exhaust control component 4 is connected to the connecting manifold 501, so that the suction force can be transmitted to the connecting manifold 501. The connecting manifold 501 can transmit the suction force to each gas collecting pipe 504 through the connecting pipe 502. The gas collecting pipe 504 can be connected to the connecting pipe 502 in each position through the set connecting sleeve 503. Through the multiple gas guide heads 505 distributed on the gas collecting pipe 504, the chlorine gas generated around each anode plate 7 can be adsorbed, so as to ensure the export and adsorption effect of chlorine gas and reduce the problem of chlorine gas diffusion and overflow.

[0035] In summary, the detachable gas collection pipe 504 allows for the control of chlorine generation at different locations, and the distributed multiple gas guide heads 505 adsorb the chlorine generated around each anode plate 7. This ensures the effective adsorption and removal of chlorine, reduces the problem of chlorine diffusion and overflow, and improves the overall collection and emission efficiency of chlorine.

[0036] Example 2

[0037] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5This is the second embodiment of the present invention, which provides an improved design for an acidic etching solution waste electrolytic cell.

[0038] Specifically, the waste liquid flow assembly 3 includes a filling pipe 301 fixedly connected to the bottom of the side wall of the tank 1, and an inlet control valve 302 fixedly installed in the middle of the filling pipe 301. The waste liquid flow assembly 3 also includes a drain pipe 303 fixedly connected to the connection between the tank 1 and the sealing top cover 2, and a drain control valve 304 fixedly installed in the middle of the drain pipe 303.

[0039] Furthermore, the waste liquid flow component 3 can control the amount of waste liquid entering and exiting the tank 1, ensuring that the waste liquid to be treated is fully electrolyzed.

[0040] Specifically, the exhaust control assembly 4 includes an assembly frame 402 fixedly installed in the middle of the control manifold 401. A control motor 403 is fixedly installed in the middle of the assembly frame 402. A fan blade 404 is fixedly installed at the output end of the control motor 403. An agitator 6 is provided both inside and outside the tank 1. The agitator 6 includes an agitator motor 601 fixedly installed on the outer wall of the tank 1. A rotating shaft 602 is fixedly installed at the output end of the agitator motor 601. Agitator blades 603 are distributed at equal angles on the outer wall of the rotating shaft 602.

[0041] Furthermore, the exhaust control component 4, in conjunction with the gas guiding component 5, can control the emission of chlorine gas, and the stirring component 6 can be used to stir the waste liquid inside the device. This allows the liquid inside the device to fully contact the anode plate 7 and the cathode plate 8, thereby improving the treatment efficiency of waste liquid electrolysis.

[0042] In use, the filling pipe 301 is connected to the external waste liquid input device. Opening the liquid inlet control valve 302 allows the external waste liquid to be transported into the tank 1. At the same time, opening the liquid outlet control valve 304 allows a large amount of waste liquid to be input into the tank 1. When the waste liquid level reaches the height of the liquid outlet pipe 303, the fully electrolyzed waste liquid can be discharged from the liquid outlet pipe 303. During electrolysis, the anode plate 7 and cathode plate 8 are energized, and the stirring motor 601 is started. The stirring motor 601 drives the rotating shaft 602 to rotate. The rotating shaft 602 can fully stir the waste liquid in the device through the stirring blades 603. This allows the flowing waste liquid to fully contact the anode plate 7 and cathode plate 8. When chlorine gas is generated on the anode plate 7, the control motor 403 is started. The control motor 403 drives the fan blades 404 to rotate. The rotation of the fan blades 404 generates a negative pressure at the control main pipe 401, which creates a negative pressure suction in the gas guiding component 5, thereby adsorbing and collecting the generated chlorine gas.

[0043] In summary, the exhaust control component 4 enables the gas guiding component 5 to have negative pressure suction, thereby adsorbing and collecting the generated chlorine gas, ensuring the overall adsorption effect of the gas guiding component 5 on the chlorine gas inside the device.
