Description

Technical Field

[0001] This utility model relates to the field of plating solution recycling technology, specifically to a device for the step-by-step recycling and separation of pre-plated nickel wire plating solution. Background Technology

[0002] In the pre-plating nickel production process, the electroplating process is a key link that directly affects product quality. The main components of the plating solution are nickel sulfate, nickel chloride and various additives. Among them, nickel is a non-renewable resource and its market price fluctuates greatly.

[0003] Currently, the multi-stage single-tank recycling systems commonly used in the industry suffer from problems such as low recycling efficiency and significant waste of plating solution, specifically:

[0004] 1. Existing equipment has limited functionality and cannot classify and recycle plating solutions of different concentrations, resulting in low utilization of the recycled solution.

[0005] 2. Ineffective control of losses carried out by the plating solution has led to increased consumption of precious metals such as nickel and persistently high production costs.

[0006] 3. Traditional recycling systems cannot completely avoid waste liquid discharge, resulting in significant environmental pressure. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for the step-by-step recycling and utilization of pre-plated nickel wire plating solution. Through technological upgrades, it achieves efficient recycling to reduce production costs and environmental pollution.

[0008] The technical solution adopted in this utility model is a device for the step-by-step recycling and utilization of pre-plated nickel wire plating solution, including a recycling system and a storage system. The recycling system and the storage system are connected together by pipelines. The recycling system includes a No. 4 recycling tank, a No. 3 recycling tank, a No. 2 recycling tank, and a No. 1 recycling tank. The storage system includes a No. 1 storage tank, a No. 2 storage tank, and a No. 3 storage tank. The No. 1 storage tank is equipped with a level gauge and a thermometer and is connected to the No. 1 recycling tank. The No. 2 storage tank is connected to the No. 2 recycling tank and the No. 3 recycling tank. The No. 3 storage tank is connected to the No. 4 recycling tank. An overflow pipe is connected between the No. 3 storage tank and the No. 2 storage tank, and a replenishment pipe is connected between the No. 2 storage tank and the No. 1 storage tank.

[0009] The No. 1 storage tank and the No. 1 recovery tank are connected by the No. 3 return pipe and the No. 1 return pipe. The No. 3 return pipe is equipped with the No. 3 switch valve, and the No. 1 return pipe is equipped with the No. 1 switch valve. The No. 3 switch valve and the No. 1 switch valve are electrically connected to a remote intelligent control system.

[0010] One end of the No. 4 reflux pipe is connected to the inlet of the No. 2 storage tank. The No. 4 reflux pipe is equipped with a No. 4 switch valve. The other end of the No. 4 reflux pipe is connected to the No. 2 reflux pipe and the No. 5 reflux pipe via a T-connector. The No. 2 reflux pipe is equipped with a No. 2 switch valve and is connected to the No. 2 recovery tank. The No. 5 reflux pipe is equipped with a No. 5 switch valve and is connected to the No. 3 recovery tank.

[0011] The No. 3 storage tank and the No. 4 recovery tank are connected by the No. 7 return pipe and the No. 6 return pipe. The No. 6 switch valve is installed on the No. 6 return pipe, and the No. 6 switch valve is also electrically connected to the remote intelligent control system.

[0012] The No. 3 storage tank and the No. 2 storage tank are of the same size, and the height of the No. 3 storage tank and the No. 2 storage tank does not exceed 1.5m. The base frame of the No. 3 storage tank is higher than the base frame of the No. 2 storage tank.

[0013] Both the No. 3 and No. 2 storage tanks are equipped with a drain outlet at the bottom of the tank body, a drain pipe at the drain outlet, and a drain valve on the drain pipe.

[0016] Pressure rollers are added to the No. 1 and No. 3 recycling tanks.

[0017] The beneficial effects of this utility model are as follows: This utility model adds a No. 2 storage tank and a No. 3 storage tank. The No. 2 storage tank is connected to the No. 2 and No. 3 recovery tanks, and the No. 3 storage tank is connected to the No. 4 recovery tank. This allows the original No. 1 storage tank to be used only by the No. 1 recovery tank, forming a three-level liquid level distinction of high, medium and low. This enables differentiated treatment for plating solutions of different concentrations, improves the purity and utilization rate of the recovered solution, and increases the plating solution recovery rate to over 95%. This solves the problems of low recovery efficiency and low utilization rate of recovered solution in single-tank systems.

[0018] In this invention, the remote intelligent control system can control the switching and flow rate of the No. 1, No. 2, No. 3, No. 4, No. 5, No. 6 return pipes and the replenishment pipe, thereby realizing automated control of the liquid levels of the No. 1, No. 2 and No. 3 storage tanks, ensuring the stability and efficiency of the recovery operation, and further optimizing the recovery efficiency.

[0019] In this invention, the No. 1 storage tank is at a high liquid level, while the No. 2 and No. 3 storage tanks are at selectable liquid levels, ensuring stable liquid levels during the recovery process.

[0020] In this invention, the number of pressure rollers in the No. 1 and No. 3 recovery tanks is increased, which significantly reduces the amount of plating solution carried out, thereby reducing nickel consumption by 2%. This solves the problem of increased consumption of precious metals such as nickel and high production costs caused by the ineffective control of plating solution carry-out losses.

[0021] In this invention, by improving the efficiency of plating solution recovery and reducing nickel consumption, the amount of waste liquid discharged is reduced by 95%, achieving the environmental protection goal of "zero discharge". Moreover, the device can be seamlessly connected with existing production lines to ensure convenient operation, solving the problem that traditional recycling systems cannot completely avoid waste liquid discharge, which causes great environmental pressure.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Referring to the attached drawings, a device for the step-by-step recycling and utilization of pre-plated nickel wire plating solution includes a recycling system and a storage system, which are connected together by pipelines. The recycling system includes a No. 4 recycling tank 1, a No. 3 recycling tank 2, a No. 2 recycling tank 3, and a No. 1 recycling tank 4.

[0026] The No. 1 storage tank 11 and the No. 1 recovery tank 4 are connected by the No. 3 return pipe 10 and the No. 1 return pipe 5.

[0027] One end of the No. 4 return pipe 23 is connected to the inlet of the No. 2 storage tank 19. The No. 4 return pipe 23 is equipped with a No. 4 switch valve 18. The other end of the No. 4 return pipe 23 is connected to the No. 2 return pipe 8 and the No. 5 return pipe 24 through a three-way pipe connector. The No. 2 return pipe 8 is equipped with a No. 2 switch valve 7 and is connected to the No. 2 recovery tank 3. The No. 5 return pipe 24 is equipped with a No. 5 switch valve 26 and is connected to the No. 3 recovery tank 2. The No. 4 switch valve 18, the No. 2 switch valve 7, and the No. 5 switch valve 26 are all electrically connected to the remote intelligent control system.

[0028] The No. 3 storage tank 21 and the No. 4 recovery tank 1 are connected by the No. 7 return pipe 22 and the No. 6 return pipe 25. The No. 6 switch valve 27 is installed on the No. 6 return pipe 25, and the No. 6 switch valve 27 is also electrically connected to the remote intelligent control system.

[0029] The No. 3 storage tank 21 and the No. 2 storage tank 19 are tanks of the same size, and the height of the No. 3 storage tank 21 and the No. 2 storage tank 19 does not exceed 1.5m. The base frame of the No. 3 storage tank 21 is higher than the base frame of the No. 2 storage tank 19.

[0030] Both the No. 3 storage tank 21 and the No. 2 storage tank 19 are equipped with a drain outlet at the bottom of the tank body. A drain pipe is provided at the drain outlet, and a drain valve is provided on the drain pipe. Both the No. 3 storage tank 21 and the No. 2 storage tank 19 are equipped with a protective cover, and the protective cover is equipped with a manhole and a manhole cover.

[0031] The replenishment pipe 14 is sequentially equipped with a switch control valve 17, a replenishment pump 16, and a flow control valve 15. The switch control valve 17, the replenishment pump 16, and the flow control valve 15 are all electrically connected to the remote intelligent control system.

[0032] The level gauge 12 and the thermometer 13 are electrically connected to the remote intelligent control system.

[0033] Pressure rollers are added to the No. 1 recycling tank 4 and the No. 3 recycling tank 2.

[0034] When this pre-plating nickel wire plating solution is in use, the plating solution in recovery tank 1 (No. 4) is returned to storage tank 21 (No. 3) through return pipes 25 (No. 6) and 22 (No. 7); the plating solution in recovery tank 2 (No. 3) is returned to storage tank 19 (No. 2) through return pipes 24 (No. 5) and 23 (No. 4); the plating solution in recovery tank 3 (No. 2) is returned to storage tank 19 (No. 2) through return pipes 8 (No. 2) and 23 (No. 4); and the plating solution in recovery tank 4 (No. 1) is returned to storage tank 11 (No. 1) through return pipes 5 (No. 1) and 10 (No. 3), thus improving the recovery efficiency and utilization rate of the plating solution.

[0035] When the liquid level in storage tank 21 is too high, the plating solution in storage tank 21 can automatically flow to storage tank 19 through overflow pipe 20. The plating solution in storage tank 19 can be automatically pumped to storage tank 11 through replenishment pipe 14 according to the liquid level. Storage tank 11 is used to replenish the plating solution consumed. Each shift, the plating solution is replenished to the plating solution storage tank according to the consumption, so as to achieve the purpose of graded recycling and utilization.

The second storage tank 19 is connected to the second recovery tank 3 and the third recovery tank 2, and the third storage tank 21 is connected to the fourth recovery tank 1. This allows the original first storage tank 11 to be used only by the first recovery tank 4, forming a three-level liquid level distinction of high, medium and low. This enables differentiated treatment for plating solutions of different concentrations, improves the purity and utilization rate of the recovered solution, and increases the plating solution recovery rate to over 95%. This solves the problems of low recovery efficiency and low utilization rate of recovered solution in single-tank systems.

[0037] In this invention, the remote intelligent control system can control the switching and flow rate of the No. 1 return pipe 5, No. 2 return pipe 8, No. 3 return pipe 10, No. 4 return pipe 23, No. 5 return pipe 24, No. 6 return pipe 25 and the replenishment pipe 14, thereby realizing the automated control of the liquid level of the No. 1 storage tank 11, the No. 2 storage tank 19 and the No. 3 storage tank 21, ensuring the stability and efficiency of the recovery operation, and further optimizing the recovery efficiency.

[0038] In this invention, the first storage tank 11 is at a high liquid level, while the second storage tank 19 and the third storage tank 21 are at optional liquid levels, ensuring stable liquid levels during the recovery process.

[0039] In this invention, the number of pressure rollers in the No. 1 recovery tank 4 and the No. 3 recovery tank 2 is increased, which greatly reduces the amount of plating solution carried out and reduces nickel consumption by 2%. This solves the problem that the loss of plating solution carried out is not effectively controlled, which leads to increased consumption of precious metals such as nickel and high production costs.

[0040] In this invention, by improving the efficiency of plating solution recovery and reducing nickel consumption, the amount of waste liquid discharged is reduced by 95%, achieving the environmental protection goal of "zero discharge". Moreover, the device can be seamlessly connected with existing production lines to ensure convenient operation, solving the problem that traditional recycling systems cannot completely avoid waste liquid discharge, which causes great environmental pressure.
