Description

Technical Field

[0001] This invention relates to the field of copper dissolution technology using electrolytic solutions, and particularly to a copper dissolution wire reaction apparatus and method. Background Technology

[0002] As is well known, the process of dissolving copper with an electrolyte solution is widely used in the copper product industry. However, in the traditional copper dissolving tank process equipment, two defects, namely insufficient contact area between the electrolyte and the copper wire to be dissolved after the electrolyte is sprayed from the top cover, and insufficient contact area between the air and the copper wire to be dissolved, are the main reasons for the slow dissolution rate of the copper wire. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a copper wire dissolving reaction device and method. The electrolyte is sprayed through a combination of a side tube structure, a central tube structure, and a top cover structure, ensuring full contact between the upper surface, sides, and middle portion of the copper wire and the electrolyte, thereby accelerating the reaction and increasing the copper dissolving rate. By installing air guide plates on both the side tube and the central tube, air is ensured to contact the copper wire to be dissolved at 360°, accelerating the oxidation reaction process, reducing energy consumption, and increasing the copper dissolving rate.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] The present invention discloses a copper wire dissolving reaction device and method, comprising a top cover, which is divided into two parts. An acid mist exhaust ring is provided on the lower side wall of the top cover. An annular liquid distribution pipe for providing electrolytic solution to the side tube is provided inside the lower tank wall of the acid mist exhaust ring. Two air guide plates are distributed at equal intervals on both sides of the side tube. A winch frame is provided between the two top covers, and a central tube is installed at the lower end of the winch frame.

[0006] As a preferred embodiment of the present invention, the central tube has a plurality of holes evenly distributed in the cross-sectional direction and staggered in the length direction; the central tube has a plurality of small holes A on its wall, and the diameter of the small holes A is in the range of 1.8mm-2.2mm.

[0007] As a preferred embodiment of the present invention, the lower end of the plurality of side tubes is a support frame, an air tube is fixedly installed at the lower end of the support frame, and a liquid collector is provided at the lower end of the air tube.

[0008] As a preferred embodiment of the present invention, the top of the two top covers is equipped with electrolyte inlet pipes, and a liquid replenishment port is provided at the lower end of one side of the top cover.

[0009] As a preferred embodiment of the present invention, a plurality of side tubes are installed at the lower end of the annular dispensing tube, and the side tubes are evenly distributed around the tank wall, with the length-direction spacing of each side tube ranging from 95mm to 105mm; a plurality of small holes B are evenly distributed on the side tubes, and the diameter of the small holes B ranges from 1.9mm to 2.1mm, with the included angle between any two small holes B being 15°.

[0010] As a preferred embodiment of the present invention, the air deflector has a width ranging from 148mm to 152mm, a thickness ranging from 7mm to 9mm, a length ranging from 4400mm to 4600mm, and is symmetrically distributed with side tubes spaced 300mm apart.

[0011] In a preferred embodiment of the present invention, the top cover includes an upper steel plate and a lower steel plate, the distance between the upper and lower steel plates being 9mm-11mm, forming the central cavity of the top cover; the lower steel plate is uniformly distributed with... Several small holes C.

[0012] A method for a copper wire melting reaction apparatus, and the steps of the method are as follows:

[0013] Step 1: First, the air flows upward from the bottom through the tube wall of the side plate under the configuration of the acid mist exhaust ring structure. When it passes through several small holes B that are evenly distributed on the side tube, it causes the electrolyte solution to flow out of the small holes B. The relative flow velocity and pressure of the solution are relatively high compared to the air, so that some of the air flows with the water column to the copper wire to be dissolved, thus accelerating the copper wire dissolution process.

[0014] Step 2: Then, by installing air guide plates on both the side tube and the central tube, the air can be made to come into full contact with the copper wire to be dissolved in 360°, which will accelerate the oxidation reaction process of the copper wire and speed up the dissolution of the copper wire.

[0015] Step 3: The combination structure of the upper and lower steel plates inside the cavity of the top cover, and the upper and lower steel plates forming the middle cavity of the top cover, allows the electrolyte solution to enter the middle cavity of the top cover through the electrolyte inlet pipe. The electrolyte solution then flows out through several small holes C evenly distributed on the lower steel plate of the cavity, and is powerfully sprayed onto the copper wire to be dissolved.

[0016] Step 4: Finally, the electrolyte is sprayed through several small holes B evenly distributed on the side tube, several small holes A on the wall of the central tube, and small holes C inside the top cover. Under the combined action, the upper surface, side, and middle part of the copper wire to be dissolved can fully contact the electrolyte, increasing the reaction contact area, thereby accelerating the reaction and completing the entire reaction process of copper dissolution rate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention utilizes a combination of electrolyte spraying through a side tube structure, a central tube structure, and a top cover structure. This ensures that the upper surface, sides, and middle portion of the copper wire are fully in contact with the electrolyte, accelerating the reaction and increasing the copper dissolution rate. By installing air guide plates on both the side tube and the central tube, air is ensured to contact the copper wire to be dissolved at 360°, accelerating the oxidation reaction process, reducing energy consumption, and increasing the copper dissolution rate.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example 1

[0032] like Figure 1-9 As shown, the present invention provides a copper wire dissolving reaction device and method, including a top cover 1, which is divided into two parts and split along the center line. An acid mist extraction ring 2 is provided on the lower side wall of the top cover 1. An annular dispensing pipe 3 is provided inside the lower end tank wall 13 of the acid mist extraction ring 2 to provide electrolytic solution to the side pipes 4. A total of nine side pipes 4 are evenly distributed around the tank wall. The side pipes 4 employ… The pipe is made of stainless steel, material 2205; two air guide plates 12 are evenly distributed on both sides of the side pipe 4, and a winch frame 8 is set between the two top covers 1. A central pipe 11 is installed at the lower end of the winch frame 8. The central pipe 11 is made of stainless steel. Stainless steel pipe, material 2205 can be selected.

[0033] The central tube 11 has several holes evenly distributed in the cross-sectional direction and staggered in the length direction; the wall of the central tube 11 has several small holes A17, and the diameter of the small holes A17 ranges from 1.8mm to 2.2mm. When the electrolyte solution is sprayed out from the small holes A17 in the wall of the central tube 11, even if the electrolyte solution is evenly distributed on the copper wire, the copper wire is the copper wire to be dissolved placed inside this reaction device.

[0034] The lower ends of several side tubes 4 form support frames 5. Air tubes 6 are fixedly installed at the lower ends of the support frames 5. In this specific implementation, a total of 3 air tubes 6 are installed. The air tubes 6 are made of square tubes (the square tubes are not numbered in the attached drawings; that is, the part connected to the air tube 6 is a square tube, as shown in the instruction manual). Figure 9 (As shown) The air enters and then flows out through the square tube and round tube vent at the bottom, evenly delivering the air from the bottom of the tank to the top.

[0035] The lower end of the air pipe 6 is equipped with a liquid collector 7, which is composed of a titanium mesh and a manifold. The outlet is connected to the copper dissolving circulation pump. All the technical means involved are well known to those skilled in the art and will not be described in detail here.

[0036] The top of the two top covers 1 are equipped with electrolyte inlet pipes 9, and a liquid replenishment port 10 is provided at the lower end of one side of the top cover 1.

[0037] The lower end of the annular separator 3 is equipped with several side tubes 4, which are evenly distributed around the tank wall 13. The distance between each side tube 4 in the longitudinal direction is between 95mm and 105mm. Several small holes B18 are evenly distributed on the side tubes 4, and the diameter of the small holes B18 is between 1.9mm and 2.1mm. The included angle between any two small holes B18 is 15°.

[0038] The air deflector 12 has a width ranging from 148mm to 152mm, a thickness ranging from 7mm to 9mm, and a length ranging from 4400mm to 4600mm. It is symmetrically distributed with the side tubes 4 at a distance of 300mm, which serves to guide airflow and strengthen the tube wall.

[0039] The top cover 1 includes an upper steel plate 14 and a lower steel plate 15, with a distance of 9mm-11mm between them, forming the central cavity 16 of the top cover; the lower steel plate 15 has evenly distributed... Several small holes C19.

[0040] A method for a copper wire melting reaction apparatus, and the steps of the method are as follows:

[0041] Step 1: First, the air flowing through the pipe wall of the side plate 4 flows upward from the bottom under the structure configuration of the acid mist exhaust ring 2. When it passes through the several small holes B18 that are evenly distributed on the side pipe 4, it causes the electrolyte solution to flow out of the small holes B18 with a relatively high flow rate and low pressure relative to the air. This causes some air to flow with the water column towards the copper wire to be dissolved, accelerating the copper wire dissolution process.

[0042] Step 2: Then, by installing air guide plates 12 on both the side tube 4 and the central tube 11, the air can be in full contact with the copper wire to be dissolved in 360°, which accelerates the oxidation reaction process of the copper wire to be dissolved and speeds up the dissolution of the copper wire.

[0043] Step 3: The combination structure of the upper steel plate 14 and the lower steel plate 15 inside the cavity of the top cover 1, and the upper steel plate 14 and the lower steel plate 15 forming the middle cavity 16 of the top cover, allows the electrolyte solution to enter the middle cavity 16 of the top cover through the electrolyte inlet pipe 9, and to flow out through several small holes C19 evenly distributed on the lower steel plate 15 of the cavity, and be powerfully sprayed onto the copper wire to be dissolved;

[0044] Step 4: Finally, the electrolyte is sprayed through several small holes B18 evenly distributed on the side tube 4, several small holes A17 on the wall of the central tube 11, and small holes C19 inside the top cover 1. Under the combined action, the upper surface, side and middle part of the copper wire to be dissolved can fully contact the electrolyte, increase the reaction contact area, thereby accelerating the reaction and completing the entire reaction process of copper dissolution rate.

[0045] Working Principle: Air near the side plate 4 flows upwards from the bottom under the configuration of the acid mist extraction ring 2. When passing through the small hole B18, the electrolytic solution flowing out of B18 has a higher velocity and lower pressure than the air, causing some air to flow with the water column towards the copper wire to be dissolved, effectively accelerating the dissolution of the copper wire. The electrolytic solution enters the top cover cavity 16 through the electrolyte inlet pipe 9. Several small holes C19 with diameters ranging from 1.5mm to 2.5mm are evenly distributed on the lower steel plate 15 at the bottom of the top cover cavity 16, allowing the electrolytic solution to flow out from the small holes C19 and be powerfully sprayed onto the copper wire to be dissolved. The electrolytic solution is sprayed through the side pipe 4, the central pipe 11, and the small holes C19 inside the top cover 1, working together to ensure that the upper surface, sides, and middle part of the copper wire to be dissolved are fully in contact with the electrolyte, increasing the reaction contact area, thereby accelerating the reaction and increasing the copper dissolution rate.

[0046] By installing air guide plates 12 on the side tube 4 and the central tube 11, the air can fully contact the copper wire to be dissolved at 360°, accelerating the oxidation reaction of the copper wire. This process reduces energy consumption and increases the copper dissolution rate. It solves the problems of insufficient contact area between the electrolyte and the copper wire to be dissolved, and insufficient contact area between the air and the copper wire to be dissolved, after the electrolyte is sprayed from the top cover 1 in the traditional method.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
