Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology generated during copper foil production, and in particular to a device for recovering waste heat from production. Background Technology

[0002] Copper foil production process refers to the process of processing copper raw materials into copper foil. Copper foil is a cathode electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. As a conductor in the PCB, it is mainly used for electromagnetic shielding and antistatic purposes. The commonly used production method is electrolysis, which often requires dissolving the copper raw material first, and then using direct current to deposit copper ions on the cathode to form copper foil. In order to ensure that various indicators meet customer requirements and maintain stability in the copper foil production process, various additives are often added. As the core material of copper foil production, some additives need to be heated according to the technical process requirements.

[0003] In the current production process, the heating of additives usually adopts water-jacket heating technology. The water storage tank is usually equipped with an electric heating tube, which is responsible for heating room temperature pure water to the required standard temperature. Then, the hot water is pumped to the water jacket to heat the additive tank and the additives inside. In order to ensure the quality of copper foil production, it is often necessary to keep the additive temperature stable. This usually means that the electric heating tube needs to operate for a long time. This practice often leads to a large amount of energy consumption and may cause resource waste. In addition, copper raw materials often undergo a large number of chemical reactions during dissolution, which often generate a lot of heat. The accumulation of a large amount of heat may pose certain safety hazards.

[0004] Therefore, those skilled in the art have provided a device for reusing waste heat from production to solve the problems mentioned in the background art. Utility Model Content

[0019] This utility model proposes a waste heat recovery device, which includes a connecting mechanism and a processing mechanism. The outer surface of the copper melting tank is equipped with a first water jacket. On the one hand, the flow of water carries away a large amount of heat generated during the melting process, achieving a certain heat dissipation effect, effectively preventing heat accumulation and reducing the probability of safety hazards. On the other hand, pure water absorbs heat in the second water jacket. When the temperature of the pure water rises to a suitable temperature, it can enter the first water jacket outside the additive tank to heat the additive. In this way, the waste heat of production can be recovered, which can greatly shorten the working time of the heating tube and thus greatly reduce the consumption of electricity.

The connection between the connecting pipe 310 and the second return pipe 307 is located between the second temperature sensor 308 and the third valve 309.

[0037] Specifically, the main water supply pipe 301 is connected to the liquid supply pump 105, which can transport pure water from the water storage tank 101 to the main water supply pipe 301. The first water supply pipe 302 can transport pure water from the main water supply pipe 301 to the second water jacket 205, and the second water supply pipe 304 can transport pure water from the main water supply pipe 301 to the first water jacket 202. The first valve 303 and the second valve 305 respectively control the first water supply pipe 302 and... The flow of pure water in the second water supply pipe 304 allows the first return pipe 306 to transport the cooled pure water from the second water jacket 205 to the water storage tank 101 for reuse. The second return pipe 307 can transport pure water that is not hot enough to the water storage tank 101 for electric heating and reuse. The connecting pipe 310 can transport pure water that has reached the appropriate temperature from the first water jacket 202 to the second water jacket 205 to realize the reuse of waste heat from production.

[0038] Working principle: When using this device to reuse waste heat from production, start the liquid supply pump 105 to deliver room temperature pure water from the water storage tank 101 to the water supply main pipe 301. Open the second valve 305, and the pure water enters the first water jacket 202 through the second water supply pipe 304. The pure water is heated by the heat in the copper melting tank 201. The heated pure water enters the second return pipe 307. The second temperature sensor 308 can detect the water temperature at this time.

[0039] When the water temperature reaches a suitable temperature, open valve 4 311, and hot pure water enters the connecting pipe 310, then enters the second water jacket 205 through the first water supply pipe 302. The hot pure water heats the additive tank 204 and the additives. After heat exchange, the water temperature will drop. The cooled pure water will return to the water storage tank 101 through the first return pipe 306 so that it can enter the next water cycle.

[0040] When the water temperature does not reach the appropriate temperature, valve 309 is opened. The water with insufficient temperature returns to the water storage tank 101 through the return pipe 307 and enters the water circulation. The water continuously passes through the water jacket 202. As heat accumulates, the water temperature rises continuously until it reaches the appropriate temperature, and then enters the above-mentioned process of recycling production waste heat.

[0041] If the heat generated in the copper melting tank 201 is insufficient, the heating tube 102 can be activated to heat the pure water until the temperature sensor 104 detects that the water temperature is suitable. Then, the liquid supply pump 105 is activated and the valve 303 is opened. The hot pure water enters the main water supply pipe 301 and the first water supply pipe 302 in sequence, and finally enters the second water jacket 205 to heat the additives. The cooled pure water returns to the water storage tank 101 through the first return pipe 306 and enters the water circulation.
