[0002] Acidic etching liquid is mainly used in etching process. Its ingredients include cupric chloride, etc. It has the characteristics of efficient and controllable etching. The copper recycling cylinder is the key equipment for processing etching liquid. Through chemical reaction and physical separation, copper recovery and recycling of etching liquid can be achieved. The treated etching liquid can be reused in the etching process, thereby realizing the recycling of resources and reducing waste liquid discharge, which not only reduces production costs but also reduces environmental pollution.

[0003] The existing Chinese patent with announcement number CN211595801U discloses an etching liquid recycling and copper extraction device, including an electrolytic cell, wherein an anode plate and a cathode copper-clad plate are respectively fixed to the top corresponding to the two sides of the electrolytic cell through brackets, a rectifier is installed on one side of the outer wall of the electrolytic cell, the cathode of the rectifier is connected to the cathode copper-clad plate, and the anode of the rectifier is connected to the anode plate. A copper scraping assembly used in conjunction with the cathode copper-clad plate is provided on the inner wall of one side of the electrolytic cell, and the copper scraping assembly includes a slide, a slider, a reduction motor, a reciprocating screw rod, a connecting rod, a sleeve frame, a tightening knob, a scraper and a knife groove. The slide is opened on the inner wall of one side of the electrolytic cell, and the reciprocating screw rod is rotatably connected inside the slide.

[0004] Although the above scheme realizes the automatic collection of copper and effectively improves the convenience of use, the acid etching solution will produce harmful gases when extracting copper, and its pungent smell will endanger the health of the staff. At the same time, the electrolysis reaction of copper extraction is an exothermic process. The device lacks temperature regulation in the cylinder, which affects the efficiency and effect of electrolysis. Therefore, it does not meet the existing needs. In this regard, we propose an acid etching solution copper extraction circulation cylinder. Utility Model Content

[0016] 1. The utility model is provided with an air suction machine at the upper end of the cylinder cover, and a purification box is provided on one side of the air suction machine. When electrolytic copper extraction is performed on the acid etching liquid through the circulating cylinder body, the cylinder cover is docked with the circulating cylinder body, and the air suction machine is started. The air suction machine will suck the gas emitted by the acid etching liquid into the purification box. An activated carbon air purification plate is provided in the purification box.

When the coolant flows, it exchanges heat with the circulation cylinder, which can cool the circulation cylinder to avoid affecting the electrolytic reaction and ensure the efficiency and effect of electrolytic copper extraction.

[0028] When in use, the suction machine 7 is started during copper electrolysis, so that the irritating gas enters the purification box 9 through the gas pipe 8. The gas can be fully purified through the three activated carbon air purification plates 10 to avoid pollution of the working environment during subsequent discharge. The purified gas will be neutralized with the fragrance emitted by the solid fragrance 11, achieving a fresher and odor-free gas emission and avoiding harm to the health of the staff.

[0029] See also Figure 1 A water pump 17 is provided on one side above the cooling chamber 15. The water pump 17 is connected to the serpentine pipe 19 and the cooling chamber 15 through a water inlet pipe 18. The setting of the water pump 17 provides power for the flow of the coolant;

[0030] See also Figure 1 and Figure 3 The serpentine tube 19 is connected to the cooling chamber 15 through the return pipe 14. The setting of the return pipe 14 can realize the reflux of the coolant and the circulation of the coolant. The setting of the serpentine tube 19 can increase the time for the coolant to pass through and improve the cooling effect.

[0031] See also Figure 1 and Figure 2 , the upper side of the inner side of the support seat 2 is equipped with a linear guide rail 3, and the moving end of the linear guide rail 3 is fixedly connected to the cylinder cover 5. The linear guide rail 3 can drive the cylinder cover 5 to be raised and lowered, thereby replacing manual labor, saving time and effort, and being easy to use;

[0032] See also Figure 1 A refrigeration mechanism 16 is installed at the lower end of the cooling chamber 15, and the cooling liquid inside the cooling chamber 15 can be cooled by the refrigeration mechanism 16, thereby ensuring the cooling effect of the cooling liquid;

[0033] See also Figure 1 and Figure 2 The lower end of the circulation cylinder 4 is bonded and fixed with a heat insulation pad 6, and the heat insulation pad 6 is bonded and fixed to the base 1. The setting of the heat insulation pad 6 can avoid isolating the cold air emitted by the cooling chamber 15 when no cooling is performed;

The setting of the sealed doors 12 is convenient for the staff to replace the activated carbon air purification board 10 inside the purification box 9 to ensure the adsorption and purification effect of the activated carbon air purification board 10.

[0035] Working principle: When in use, add the acid etching liquid into the inside of the circulation cylinder 4, start the linear guide 3 to move the cylinder cover 5 downward, so as to avoid the escape of the smell of the acid etching liquid and avoid polluting the working environment. The acid etching liquid can be electrolytically extracted copper through the anode plate and the cathode plate in the circulation cylinder 4. At this time, the air suction machine 7 can be started, and the air suction machine 7 will suck the gas inside the circulation cylinder 4 into the inside of the purification box 9 through the air pipe 8. After the gas enters the purification box 9, it will pass through three activated carbon air purification plates 10 in turn. The activated carbon air purification plate 10 can fully purify the gas to avoid polluting the working environment during subsequent discharge. The purified gas will be neutralized with the fragrance emitted by the solid aromatic agent 11, so as to obtain a fresher and odor-free gas emission to avoid endangering the health of the staff. When electrolytic copper extraction, the acid etching liquid can be real-timely measured through the water temperature sensor 13. For temperature monitoring, the water temperature sensor 13 will transmit the temperature data to the single-chip microcomputer (prior art, not shown in the figure) through an electrical signal. The staff can pre-set the standard temperature range, and the single-chip microcomputer can compare the monitored temperature with the preset value. When the temperature is too low, the single-chip microcomputer will start the water pump 17, and the water pump 17 will transport the coolant inside the cooling chamber 15 to the serpentine tube 19 through the water inlet pipe 18. When the coolant passes through the serpentine tube 19, it can exchange heat with the circulation cylinder 4, thereby effectively reducing the temperature of the circulation cylinder 4, avoiding affecting the electrolytic reaction, and ensuring the efficiency and effect of electrolytic copper extraction. After passing through the serpentine tube 19, the coolant will return to the inside of the cooling chamber 15 through the return pipe 14 for the next cooling, thereby achieving the effect of circulating cooling. The coolant inside the cooling chamber 15 can be refrigerated by the refrigeration mechanism 16, thereby ensuring the cooling effect of the coolant.
