Description

Technical Field

[0001] This application relates to the field of copper recycling technology, specifically to equipment for recovering copper from micro-etching waste liquid from circuit boards. Background Technology

[0002] As the name suggests, the copper recovery equipment for circuit board micro-etching waste liquid is a special equipment for treating copper-containing waste liquid generated after the circuit board micro-etching process. Its main function is to reduce copper ions in the waste liquid to metallic copper through processes such as electrolysis, thereby realizing the recycling and reuse of copper resources.

[0003] For example, patent CN222499413U discloses a copper recovery device for circuit board micro-etching waste liquid. This patent uses a third motor to drive an elastic rod to rotate two striking blocks, which in turn strike the negative electrode plate, causing the elemental copper attached to the negative electrode plate to fall onto the collection box.

[0004] Most existing copper recovery equipment for circuit board micro-etching waste liquid adopts a single-sided cathode plate design. During the electrolysis process, copper ions are reduced to metallic copper and deposited on the surface of the cathode plate. When the copper deposited on one side of the cathode plate reaches a certain thickness, the electrolysis operation needs to be stopped, the cathode plate is removed from the waste liquid, and the copper is stripped and collected. During this process, the equipment needs to be stopped and wait, resulting in discontinuous electrolysis operation, low equipment utilization, and low overall production efficiency.

[0005] Therefore, it is necessary to provide equipment for recovering copper from micro-etching waste liquid of circuit boards to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2 As shown, this application provides a copper recovery equipment for circuit board micro-etching waste liquid. The copper recovery equipment for circuit board micro-etching waste liquid is installed in the waste liquid treatment area after the circuit board micro-etching process. It is mainly used to extract metallic copper from the circuit board micro-etching waste liquid (hereinafter referred to as waste liquid). Specifically, the copper recovery equipment for circuit board micro-etching waste liquid includes a box 1 fixedly installed in the waste liquid treatment area, and an electrolytic cell 2 is opened at the middle position of the upper end of the box 1. The electrolytic cell 2 is used to contain the circuit board micro-etching waste liquid.

[0036] Meanwhile, a feed inlet 9 is fixedly provided on one side of the tank 1. The feed inlet 9 is connected to the electrolytic cell 2 so that the waste liquid can be introduced into the electrolytic cell 2. At the same time, a discharge outlet 7 is fixedly provided on the tank 1. The discharge outlet 7 is also connected to the electrolytic cell 2 so that the waste liquid can be discharged for use.

[0037] Meanwhile, an anode plate 3 is fixedly installed on the inner wall of the electrolytic cell 2. The anode plate 3 is a mesh frame structure and covers the inner wall of the electrolytic cell 2. The anode plate 3 serves as the anode of the electrolytic reaction and is responsible for transmitting current and guiding the oxidation reaction.

[0038] In order to carry out subsequent electrolysis operations, columns 4 are fixedly installed at both ends of the tank 1 located in the electrolysis cell 2, and crossbeams 5 are fixedly installed between the columns 4.

[0039] In order to achieve the effect of electrolysis without stopping the machine, such as Figures 1-4 As shown, a switching mechanism 6 is provided on the crossbeam 5. The switching mechanism 6 includes a rotary cylinder 60 fixedly installed at the lower end of the crossbeam 5, and a horizontal plate 61 is fixedly installed at the output end of the rotary cylinder 60. Thus, the horizontal plate 61 can be driven to rotate at the lower end of the crossbeam 5 by starting the rotary cylinder 60.

[0040] Furthermore, a first work station 610 is provided at one end of the horizontal plate 61. The first work station 610 includes a cylinder 62 fixedly installed at the upper end of the horizontal plate 61. The output end of the cylinder 62 passes through the horizontal plate 61 and is fixedly connected to a fixing plate 63. A slot 64 is provided on the fixing plate 63, and a cathode plate 65 is inserted into the slot 64. It should be noted that when the cathode plate 65 is inserted into the slot 64, the cathode plate 65 inside the slot 64 can be fixed by setting bolts on both sides of the fixing plate 63.

[0041] When performing electrolysis, the cathode plate 65 can first be placed inside the slot 64. Then, the rotary cylinder 60 is started to move the first station 610 to the top of the electrolytic cell 2. Then, the cathode plate 65 is pushed into the electrolytic cell 2 by the cylinder 62 until it is immersed in the waste liquid. Finally, the anode plate 3 and the cathode plate 65 are energized to perform electrolysis. During the electrolysis process, copper ions in the waste liquid are reduced to metallic copper on the surface of the cathode plate 65 and deposited.

[0042] Meanwhile, a second station 611 is provided at the other end of the horizontal plate 61. The second station 611 is the same as the first station 610. So when the electrolysis operation is completed, the horizontal plate 61 can be driven by the rotary cylinder 60 to switch between the first station 610 and the second station 611, thereby achieving the purpose of rapid electrolysis operation.

[0043] In order to collect the copper on the cathode plate 65, a scraping mechanism 8 is provided on the side of the upper end of the box 1 located in the electrolytic cell 2. The scraping mechanism 8 scrapes the surface of the cathode plate 65 to clean the metallic copper on the surface of the cathode plate 65.

[0044] The scraping mechanism 8 includes a base 80 fixedly mounted on the upper end of the housing 1, and fixed columns 82 fixedly mounted on both sides of the upper end of the base 80. A connecting rod 83 is fixedly mounted on the inner side of the fixed column 82, and a scraper 84 is fixedly mounted on one end of the connecting rod 83. It should be noted that the two scraper 84s are coaxially arranged, thereby forming a gap between the two scraper 84s. The size of the gap matches the size of the cathode plate 65, so that the cathode plate 65 can be scraped in the future.

[0045] Furthermore, a collection box 81 is provided at the lower end of the gap on the upper end of the base 80. This collection box 81 is used to collect the metallic copper scraped off the cathode plate 65.

[0046] It should be noted that when the first station 610 is directly above the electrolytic cell 2, the cathode plate 65 on the second station 611 is directly above the gap between the two scrapers 84. Thus, when the first station 610 drives the cathode plate 65 to complete the electrolysis operation, the position can be switched with the second station 611 by starting the rotary cylinder 60. Then the cathode plate 65 on the second station 611 can continue to perform the electrolysis operation, while the cathode plate 65 on the first station 610 can enter the gap between the two scrapers 84 under the drive of the cylinder 62 to perform the scraping operation. In this way, the electrolysis operation can be carried out without stopping the machine.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
