Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to a drying furnace body for a copper strip electroplating production line. Background Technology

[0002] During the copper strip electroplating process, residual electrolyte and other liquids remain on the surface of the electroplated copper strip, requiring drying to ensure the quality of the copper strip and the smooth progress of subsequent processing. Currently, the industry mainly uses two methods for drying electroplated copper strips: natural air drying and fan drying.

[0003] Natural air drying is greatly affected by environmental factors such as temperature, humidity, and air flow speed, resulting in extremely low drying efficiency. It cannot meet the needs of large-scale, continuous production. Moreover, during the drying process, the surface of the copper strip is easily contaminated with dust and other impurities, affecting product quality.

[0004] While fan drying is more efficient than natural air drying, it still has significant drawbacks. On the one hand, fan drying struggles to achieve uniform drying of the copper strip, easily resulting in incomplete drying in certain areas. On the other hand, this method requires a continuous large amount of electricity to drive the fan, leading to high energy consumption, which does not align with current energy-saving and environmentally friendly production principles.

[0005] Therefore, it is of great significance to provide a drying furnace body for copper strip electroplating production lines that can solve the problems existing in the current technology. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a drying furnace body for a copper strip electroplating production line to solve the problem.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A drying furnace body for a copper strip electroplating production line includes a combustion chamber, a cooling chamber, a heating chamber, and a preheating chamber. The preheating chamber is located above the heating chamber, and the cooling chamber is located below the heating chamber, forming a continuous drying channel from top to bottom.

[0009] The cooling chamber is equipped with an exit roller to guide the movement of the copper strip; the bottom of the heating chamber is equipped with a flat, elongated heating chamber outlet for the copper strip to pass through and enter the cooling chamber; the top of the preheating chamber is equipped with a flat, elongated copper strip inlet, and an inlet roller is installed above the copper strip inlet to guide the copper strip into the preheating chamber; the top of the preheating chamber is also connected to an exhaust pipe for discharging waste gas.

[0010] The combustion chamber has an air inlet connected to a circulating fan, the heating chamber has an air outlet connected to the air inlet of the circulating fan, and the heating chamber has an air inlet connected to the combustion chamber's air outlet, forming a hot air circulation system.

[0011] Furthermore, both the heating chamber outlet and the copper strip inlet are flat and elongated strip structures to accommodate the shape of the copper strip and reduce heat loss.

[0012] Furthermore, the outer wall of the heating chamber is provided with an insulation layer, and the preheating chamber is located outside the insulation layer to improve the efficiency of thermal energy utilization.

[0013] Furthermore, the cooling chamber is equipped with a low-temperature nitrogen inlet pipe and a high-temperature nitrogen outlet pipe for rapidly cooling the copper strip and recovering waste heat.

[0014] Furthermore, the inlet roller, copper strip inlet, heating chamber outlet, and outlet roller are arranged along the same vertical line to ensure that the copper strip maintains stable operation during the drying process.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Reduced floor space: This utility model adopts a vertical drying oven structure, with the preheating chamber, heating chamber and cooling chamber arranged sequentially from top to bottom to form a three-dimensional continuous drying channel. Compared with traditional horizontal drying equipment, it greatly reduces the floor space and is conducive to the rational use of space in the production workshop.

[0017] 2. Improved Drying Efficiency: By setting up a preheating chamber, a heating chamber, and a cooling chamber, continuous drying of the copper strip is achieved, avoiding the low efficiency problems of natural air drying and simple fan drying, and meeting the needs of large-scale continuous production. At the same time, the inlet roller, copper strip inlet, heating chamber outlet, and outlet roller are arranged along the same vertical line to ensure stable operation of the copper strip, further improving the continuity and efficiency of drying.

[0018] 3. Energy-saving and environmentally friendly, with low energy consumption: The combustion chamber, heating chamber, and circulating fan form a hot air circulation system, enabling heat recycling, reducing heat waste, and lowering energy consumption. The insulation layer on the outer wall of the heating chamber, as well as the flat, elongated heating chamber outlet and copper strip inlet, effectively reduce heat loss and improve thermal efficiency. Furthermore, the cooling chamber uses low-temperature nitrogen to cool the copper strip, and the high-temperature nitrogen outlet pipe can recover waste heat, further achieving energy savings and making it more environmentally friendly.

[0019] 4. Ensure drying quality: The continuous drying channel and stable copper strip operation ensure that the copper strip is heated evenly and dried more thoroughly, avoiding problems such as localized inadequate drying and ensuring the drying quality of the copper strip.

[0030] Please see Figure 1-2 This utility model provides a technical solution for a drying furnace body used in a copper strip electroplating production line:

[0031] A drying furnace body for a copper strip electroplating production line includes a combustion chamber 5, a cooling chamber 1, a heating chamber 7, and a preheating chamber 9. The preheating chamber 9 is located above the heating chamber 7, and the cooling chamber 1 is located below the heating chamber 7. Together, they form a continuous drying channel from top to bottom. The copper strip enters from the preheating chamber 9 and passes through the heating chamber 7 and the cooling chamber 1 in sequence to complete the entire drying process.

[0032] The cooling chamber 1 is equipped with an output roller 2, whose main function is to guide the movement of the cooled copper strip and ensure that the copper strip can be smoothly output from the drying furnace. The bottom of the heating chamber 7 is provided with a flat and elongated heating chamber outlet 3. The shape of the outlet matches the shape of the copper strip, which facilitates the copper strip to enter the cooling chamber 1 from the heating chamber 7. At the same time, the flat and elongated structure can reduce the heat loss from the heating chamber 7 to the outlet.

[0033] The top of the preheating chamber 9 is equipped with a flat, elongated copper strip inlet 11, designed to accommodate the shape of the copper strip and reduce heat loss. Above the copper strip inlet 11, an inlet roller 12 is installed to accurately guide the copper strip to be dried into the preheating chamber 9. An exhaust pipe 10 is also connected to the top of the preheating chamber 9, allowing waste gas generated during the drying process to be discharged, preventing waste gas from accumulating inside the furnace and affecting the drying effect and the quality of the copper strip.

[0034] The intake end of combustion chamber 5 is connected to a circulating fan 13, and the exhaust end of heating chamber 7 is connected to the intake end of circulating fan 13. The intake end of heating chamber 7 is also connected to the exhaust end of combustion chamber 5, thus forming a complete hot air circulation system. The hot air generated in combustion chamber 5 enters heating chamber 7 to heat and dry the copper strip. The hot air exhausted from heating chamber 7 returns to combustion chamber 5 for reheating under the action of circulating fan 13, achieving heat recycling and effectively reducing energy consumption.

[0035] The outer wall of the heating chamber 7 is covered with an insulation layer 8, which is made of a high-temperature resistant and heat-insulating material. This reduces heat exchange between the heating chamber 7 and the external environment, further improving thermal energy utilization efficiency. The preheating chamber 9 is located outside the insulation layer 8. This allows the small amount of heat emitted from the heating chamber 7 through the insulation layer 8 to preheat the copper strip entering the preheating chamber 9, thereby improving energy utilization.

[0036] The cooling chamber 1 is equipped with a low-temperature nitrogen inlet pipe and a high-temperature nitrogen outlet pipe. The low-temperature nitrogen enters the cooling chamber 1 through the low-temperature nitrogen inlet pipe and exchanges heat with the heated and dried copper strip, causing the copper strip to cool down rapidly. The nitrogen that absorbs the heat from the copper strip rises in temperature and becomes high-temperature nitrogen, which is discharged from the cooling chamber 1 through the high-temperature nitrogen outlet pipe. This high-temperature nitrogen can be collected and used in other processes that require heat, realizing waste heat recovery.

[0037] The inlet roller 12, the copper strip inlet 11, the heating chamber outlet 3, and the outlet roller 2 are arranged along the same vertical line. This ensures that the copper strip moves in a straight line throughout the drying process, avoiding deviations or wrinkles, and ensuring stable operation of the copper strip, thereby guaranteeing the drying quality.

[0038] The working process of this utility model is as follows: The copper strip to be dried is guided by the inlet roller 12 and enters the preheating chamber 9 through the copper strip inlet 11, where it is preheated. Then the copper strip enters the heating chamber 7 and is heated and dried under the action of hot air provided by the hot air circulation system. After drying, the copper strip enters the cooling chamber 1 through the heating chamber outlet 3 and is rapidly cooled by the cooling effect of low-temperature nitrogen. Finally, the cooled copper strip leaves the drying furnace under the guidance of the outlet roller 2, completing the entire drying process.

[0039] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
