Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic copper production, and particularly relates to an electrolytic copper anti-oxidation tank. Background Art

[0002] The patent document with publication number CN211686493U mentions that electrolytic copper is widely used in various fields of production. During the production and storage of electrolytic copper, oxidation discoloration is very likely to occur, causing considerable losses to enterprises producing or selling electrolytic copper. How to prevent electrolytic copper from oxidation is one of the key issues that need to be solved in the production and storage of electrolytic copper. So far, electrolytic copper production and sales enterprises have taken a variety of effective protective measures to reduce the degree of oxidation discoloration of electrolytic copper. The effective measures taken in the production process mainly include the use of drawing oil containing oxidants, the use of antioxidants in the continuous annealing process, and passivation treatment of the surface of electrolytic copper. In terms of actual storage, the probability of electrolytic copper being oxidized is mainly reduced by appropriately wrapping the electrolytic copper during storage and isolating external oxidizing factors such as humid air and water.

[0003] Due to the limitations of the production method of electrolytic copper, the electrolytic cell is filled with electrolyte, resulting in very high air humidity above the electrolytic cell. In conventional production, the moisture on the electrolytic copper layer is drained to prevent moisture from remaining on the cathode copper layer and accelerating the oxidation of the electrolytic copper. However, conventional drainage cannot completely remove the moisture on the cathode copper layer, and the moisture in the humid air flow on the electrolytic cell will also adhere to the electrolytic copper layer, affecting the anti-oxidation ability of the electrolytic copper layer. Therefore, the existing technology requires an electrolytic cell equipment that can reduce the moisture attached to the electrolytic copper layer to improve the anti-oxidation ability of the electrolytic copper layer.

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] An electrolytic copper anti-oxidation tank comprises: a tank body 1, conductive strips 2, a sub-platform 3, and an air pump 4; the tank body 1 is the main body of the electrolytic tank (the tank body 1 also has other necessary mechanisms for realizing the function of the electrolytic cell, and the specific structure of the tank body 1 is omitted because it belongs to the prior art and has little relevance to the present application), and the tank body 1 is provided with two groups of parallel conductive strips 2 for conducting the electrolytic plate; a sub-platform 3 is provided on the side of the tank body 1, and an air pump 4 is fixed on the sub-platform 3, the gas outlet end of the air pump 4 is vertically arranged upward, and is connected to a heater 6 for gas heating through a pipeline, and the gas outlet of the heater 6 is extended to the top of the tank body 1 through a vertical vertical pipe 11 and connected to a horizontal main nozzle 7, and the main nozzle 7 is parallel to the two groups of conductive strips 2 of the tank body 1; the main nozzle 7 is provided with a spray drying head 9 that can adjust the jet angle.

[0026] In order to enable the spray drying head 9 to have an angle adjustment capability, the spray drying head 9 comprises: a tube seat 91, a spherical head 92, a spherical shell 93, a nozzle 94, and a nozzle 95; the tube seat 91 is a diameter-reducing circular body horizontally arrayed on the main nozzle 7, and the end of the tube seat 91 away from the main nozzle 7 is a spherical head 92 with a spherical structure, and the side of the spherical head 92 away from the tube seat 91 is provided with an opening for gas circulation, the spherical shell 93 is externally embedded on the spherical head 92 to form a ball joint connection, and the other side of the spherical shell 93 is connected to the nozzle 94, and the nozzle 94 is provided with a nozzle 95, and the nozzle 95 is communicated with the cavity inside the spherical shell 93.

[0027] In order to increase the drying spray range and drying jet velocity of the nozzle 95 , the nozzle 95 side of the nozzle 94 is distributed in an elongated shape, the number of the nozzles 95 is not less than one group, and the nozzles 95 are distributed in a linear array on the nozzle 94 .

[0028] In order to increase the efficiency of thermal drying and to make the drying spray more uniform, the upper part of the vertical pipe 11 is connected to a secondary nozzle 8 through a tubular cross-connecting pipe 13. The secondary nozzle 8 and the main nozzle 7 are symmetrical structures. The secondary nozzle 8 is provided with a spray drying head 9 corresponding to the spray drying head 9 on the main nozzle 7.

[0029] In order to enable the air pump 4 to have rotational power, a motor 10 is fixed on the auxiliary platform 3, and the output end of the motor 10 and the input end of the air pump 4 are coaxially fixedly connected.

[0030] In order to realize automatic air supply when air supply is needed, a valve is connected to the air inlet end of the air pump 4 to form an air inlet valve 5, and the air inlet valve 5 is a solenoid valve or a manual solenoid dual-purpose valve.

[0031] In order to prevent the nitrogen from expanding due to heat, which may cause the nozzle 95 to release pressure in time, a pressure relief valve is provided at the air inlet or outlet of the air pump 4.

[0032] In order to avoid excessive angular deviation between the nozzle 95 and the electrolytic plate during spraying, the tank body 1 needs to be kept horizontal, and a leveling foot 14 is provided at each of the four corners of the bottom of the tank body 1.

[0033] When in use, copper electrolyte is injected into the tank body 1, and an electrolytic plate (not shown in the figure) is set between two groups of conductive strips 2. The cathode of the electrolytic plate is immersed in water, and positive and negative electrodes are connected to the conductive strips 2. The conductive strips 2 supply power to the electrolytic plate. The copper ions in the copper electrolyte adhere to the cathode of the electrolytic plate to form a copper layer. When the copper layer is formed to a specified thickness, the electrolytic plate and the copper layer thereon need to be hoisted as a whole, and all the electrolytic plates are hoisted by a crane and a hoisting device, and all the electrolytic plates are placed between the main nozzle 7 and the auxiliary nozzle 8.

The heater 6 is energized to work, and the heater 6 heats the nitrogen and conveys it to the main nozzle 7 and the auxiliary nozzle 8 through the vertical pipe 11. The main nozzle 7 and the auxiliary nozzle 8 The nozzle 8 diverts the airflow and guides it into each spray drying head 9. The array-distributed nozzles 95 on the spray drying head 9 blow the hot nitrogen flow to the surface of the copper layer on the electrolytic plate to quickly dry the moisture on the copper layer. At the same time, because the blown gas is nitrogen, nitrogen is an inert gas and will not accelerate the oxidation of the copper layer surface. Therefore, the warm nitrogen flow can prevent the wet copper layer from being oxidized, reduce the probability of electrolytic copper being oxidized, reduce the degree of oxidative discoloration of electrolytic copper, and improve the sales quality of the product. After the spraying is completed, keep the air inlet valve 5 and the air pump 4 open, temporarily turn off the heater 6, let the nitrogen flow blow away the wet airflow above the tank body 1, then hoist the electrolytic plate and the copper layer thereon as a whole for storage, then close the air inlet valve 5 and the air pump 4, and carry out the next electrolytic copper operation. When it is necessary to adjust the angle of the nozzle 95, the spherical joint structure formed around the spherical head 92 and the spherical shell 93 can be used to deflect the nozzle 94.
