Description

Technical Field

[0001] This utility model relates to the technical field of copper foil production equipment, and more specifically, to a fresh air drying system that facilitates uniform airflow. Background Technology

[0002] In the production process of raw copper foil, after the copper foil stripped from the cathode roller is immersed in an anti-oxidation tank, excessive anti-oxidation solution residue easily adheres to its surface. If such residue is not effectively removed, it will not only cause oxidation on the surface of the copper foil, leading to quality deterioration, but will also form interface contamination in subsequent surface treatment processes. Therefore, the copper foil needs to be dried. During the drying process of copper foil, extremely high requirements are often placed on drying uniformity, surface cleanliness, and energy consumption control, especially for high-precision applications, such as lithium battery negative electrode current collectors and ultra-thin copper foil for electronic circuits. The surface quality, namely flatness, absence of obvious spots or wrinkles, moisture content, and stability of the production process, directly affects the reliability and yield of subsequent processes.

[0003] The closest existing drying oven to this application is the one authorized by publication number CN211876554U, which is a secondary circulation system for hot exhaust gas in a dryer. Air enters the hot air furnace through the air inlet and is heated to the required temperature. After reaching the required temperature, the air enters the drying oven through the hot air outlet and the hot air inlet pipe. After drying, the hot exhaust gas containing water vapor is discharged through the hot exhaust gas pipe. The hot exhaust gas enters the condenser from the hot exhaust gas pipe. Under the action of the condenser fan, the water vapor is condensed into liquid and discharged through the drain pipe. The dehumidified hot exhaust gas is output from the recovered hot gas outlet and enters the hot air furnace for recycling through the recovered hot gas pipe.

[0004] The drying oven described above can only achieve air circulation, but it does not have an energy storage module. This makes it impossible to avoid the sudden rise or fall in temperature caused by the intermittent operation of the hot air furnace, resulting in significant energy loss.

[0005] In view of this, the present invention provides an energy-saving, stable output, and easy-to-distribute fresh air drying system. Utility Model Content

[0006] The purpose of this invention is to propose an energy-saving, stable-output, and easy-to-distribute fresh air drying system.

[0007] A fresh air drying system that facilitates uniform airflow, characterized in that it includes:

[0008] The drying box module 1 is equipped with a material inlet and a material outlet distributed along the material travel direction, and forms a three-dimensional drying channel 2 inside, which includes drying chambers arranged symmetrically at the top and bottom;

[0009] The first transfer module 3 is connected to the return air end of the drying box module 1;

[0010] The condenser module 4 is connected to the first transfer module 3 and is used to condense and dehumidify the return air;

[0011] The heating unit control module 5 is connected to the output terminal of the condenser module 4 and is used to heat the dehumidified return air.

[0012] The energy storage module 6 is connected to the output terminal of the heating unit control module 5. The energy storage module 6 is used to temporarily store or stably output hot air that meets the set temperature. Firstly, it balances the instantaneous air volume fluctuations between the heating unit control module 5 and the drying box module 1 to ensure a constant temperature during the drying process and avoid sudden temperature rises or falls caused by the operation of the heating unit control module 5. Secondly, during non-continuous drying or low-load operation, the energy storage module 6 can store excess heat energy, reduce energy loss caused by the start and stop of the heating unit control module 5, and provide a buffer for sudden high-load demands.

[0013] The second transfer module 7 is connected to the energy storage module 6 and communicates with the air inlet of the drying box module 1, and is used to send hot air back to the drying box module 1; a filter unit 8 is provided between the energy storage module 6 and the output end of the heating unit control module 5 and the input end of the second transfer module 7, which plays a role in preventing local turbulence from rectifying the air outlet and uniformizing the wind speed.

[0014] Furthermore, the end of the energy storage module 6 near the second transfer module 7 has a flared structure to increase airflow speed, enhance hot air penetration, and avoid drying dead zones caused by insufficient airflow.

[0015] In some embodiments, the filter unit 8 is a multi-layer filter structure, which includes at least two filter layers, and more preferably more than three layers. The multi-layer filter structure slows down the wind speed to prevent the high-temperature airflow output by the heating unit from directly impacting the material surface, thus avoiding uneven drying or hardening of the material surface.

[0016] Furthermore, the multi-layer filtration structure includes a rectifier layer, a metal wire mesh layer, and a fine filter layer arranged in sequence, which are used to disperse airflow, intercept impurities, and improve the uniformity of outlet air velocity.

[0017] Furthermore, the rectifier layer has a pore size of 5mm-10mm, which is used for pre-rectification of large particulate impurities and airflow.

[0018] Furthermore, the metal mesh layer has a pore size of 1mm-3mm, which is used to disperse airflow and perform coarse filtration.

[0019] Furthermore, the fine filter layer has a pore size of 0.3mm-1mm, which is used for microparticle interception and wind speed equalization.

[0020] Furthermore, a high-temperature fiber layer is provided at the output end of the fine filter layer to prevent hot air from carrying out extremely fine dust and improve air cleanliness.

[0021] In some implementations, the filter unit 8 has a pull-out structure for quick disassembly and assembly, which enables rapid filter replacement and maintenance while ensuring stable operation in high-temperature environments, thus reducing downtime.

[0022] Furthermore, the pull-out filter unit 8 is also equipped with a high-temperature sealing frame and a high-temperature resistant gasket to achieve stable sealing in high-temperature operating environments.

[0023] The beneficial effects of this utility model are as follows: This utility model proposes a fresh air drying system that facilitates uniform airflow. By connecting an energy storage module 6 to the output end of the heating unit control module 5, the energy storage module 6 can balance the instantaneous airflow fluctuations between the heating unit control module 5 and the drying chamber module 1, ensuring a constant temperature during the drying process and avoiding sudden temperature rises or falls caused by the operation of the heating unit control module 5. At the same time, during discontinuous drying or low-load operation, the energy storage module 6 can store excess heat energy, reducing energy loss caused by the start and stop of the heating unit control module 5, and providing a buffer for sudden high-load demands. The energy storage module 6 is designed with a flared structure near the second transfer module 7 to increase the airflow velocity. The filter unit 8 has a multi-layer filter structure to balance the airflow velocity and eliminate the interference of turbulence on the uniformity of airflow. Attached Figure Description
