Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery coating and drying equipment, and in particular to a lithium battery coating and drying box. Background Technology

[0002] Currently, the most commonly used coating technology for lithium batteries is wet coating, which involves mixing active materials, conductive agents, binders, and other components with solvents in a specific ratio to form a slurry. This slurry is then uniformly coated onto the surfaces of the positive and negative electrode materials using a coating die. After coating, the electrode materials need to undergo a drying process to remove the solvent and ensure the stability and good electrical performance of the battery materials. The efficiency of the drying process directly affects the battery's performance and the improvement of production efficiency.

[0003] Currently, many lithium battery coating machines heat the coating material in their drying chambers by placing heating elements, such as heating tubes or heating wires, near the material. Because the heating elements directly heat the material, this method suffers from low drying efficiency. Furthermore, heat easily escapes from the sides of the drying chamber, leading to heat waste and low energy efficiency, further increasing production costs.

[0004] To address the aforementioned technical problems, existing technologies utilize circulating fans to blow heat generated by the heating elements onto the coating material, thereby improving heat utilization. However, during the drying process, as the heating time increases, the solvent in the coating material evaporates, leading to increased humidity inside the drying chamber and delaying the drying time and efficiency of the coating material.

[0005] Therefore, how to avoid the impact of humidity inside the lithium battery coating drying oven on drying efficiency has become an urgent technical problem to be solved. Utility Model Content

[0006] The main purpose of this invention is to provide a lithium battery coating drying box that avoids the impact of humidity inside the lithium battery coating drying box on drying efficiency.

[0007] To achieve the above objectives, this utility model proposes a lithium battery coating and drying oven, comprising:

[0008] The drying oven body has a drying station inside that allows the parts to be dried to pass through;

[0009] At least one circulating heating component is disposed within the drying chamber body, capable of generating heat, and cooperates with the inner wall of the drying chamber body to form a circulating air duct, so as to circulate and guide the generated heat to the surface of the workpiece to be dried; and

[0010] An adsorption component is disposed within the circulating air duct and is used to dry the gas within the circulating air duct.

[0011] The circulating heating element generates stable and continuous heat, forming an effective circulating air duct with the inner wall of the drying chamber. This allows heat to circulate continuously and be evenly distributed within the chamber. This ensures that moisture on the surface of the parts to be dried evaporates quickly, avoiding the uneven heat distribution or localized overheating problems of traditional heating methods, significantly improving drying efficiency. The adsorption element within the circulating air duct effectively removes moisture from the air, keeping the airflow dry and preventing the re-accumulation of moisture. This not only improves drying efficiency but also reduces energy waste and the negative impact of moisture on drying performance.

[0012] In one embodiment of this application, the circulating heating assembly includes:

[0013] A fixed horizontal partition is connected to the drying chamber body to form a circulation space inside the drying chamber. The fixed horizontal partition is provided with through holes and circulation holes, and the working surface of the fixed horizontal partition faces the drying station.

[0014] A heating element is disposed within the through hole to generate heat, and a gap is left between the heating element and the through hole;

[0015] A heating fan, located within the circulation space, is used to guide the heat generated by the heating element to the drying station; and

[0016] A circulating fan is located inside the circulating hole to guide the airflow passing through the drying station into the circulating space. The adsorption element is located at the air outlet of the circulating fan.

[0017] The heating element directly heats the air, and the heated air is then effectively transported to the drying station by a heating fan, ensuring uniform heat distribution and improving drying efficiency. The circulating fan guides airflow within the drying chamber, allowing the hot air to pass through the drying station multiple times, further enhancing heat utilization efficiency. Adsorption components effectively remove moisture from the air, keeping the airflow within the drying chamber dry and preventing moisture from affecting drying efficiency. This effectively improves energy efficiency in the drying process, reduces heat waste, and accelerates the drying speed of the coated material.

[0018] In one embodiment of this application, the circulating heating assembly further includes:

[0019] A fixed vertical partition is vertically connected to the fixed horizontal partition and located between the through hole and the circulation hole, used to divide the circulation space into an inner circulation space and an outer circulation space. The fixed vertical partition is provided with a connecting hole that connects the inner circulation space and the outer circulation space; the adsorption component is located in the outer circulation space.

[0020] By introducing fixed vertical baffles into the circulating heating assembly, different zones of the circulating space are effectively divided, making the airflow inside the drying chamber more orderly and efficient. The fixed vertical baffles separate the inner and outer circulating spaces, allowing the heating and moisture absorption processes to proceed independently. The adsorption assembly, located in the outer circulating space, effectively adsorbs moisture from the hot air before it recirculates, thereby reducing the negative impact of moisture on the drying process and ensuring its continuity and stability.

[0021] In one embodiment of this application, the circulating heating assembly further includes:

[0022] A guide plate is connected on the first side to the fixed vertical partition to form an air intake channel in the circulation space, and the adsorption component can abut against the air inlet of the air intake channel.

[0023] The deflector effectively guides the airflow, preventing irregular flow and facilitating the smooth entry of hot air into the circulation space. This improves the utilization efficiency of the hot airflow and avoids heat waste. The adsorption component, located at the air inlet, ensures that the airflow entering the circulation space is fully dried before recirculation, preventing moisture accumulation and maintaining the drying efficiency of the airflow.

[0024] In one embodiment of this application, the adsorption component includes:

[0025] The drying oven body has a plug-in interface for inserting or removing the plug-in plate, and the plug-in plate has mounting through holes; and

[0026] Moisture-absorbing cotton is placed inside the mounting through hole.

[0027] By designing the absorbent components to be pluggable, the replacement and maintenance of the entire absorbent cotton becomes simpler and more efficient, ensuring the effectiveness of its moisture absorption function.

[0028] In one embodiment of this application, the adsorption assembly further includes an activated carbon filter plate disposed within the mounting through hole and stacked with the moisture-absorbing cotton.

[0029] By stacking activated carbon filter plates with moisture-absorbing cotton, a dual purification and moisture-absorbing structure is formed, which significantly improves the air purification and drying effect.

[0030] In one embodiment of this application, the plug-in board is provided with a first handle. The first handle on the plug-in board facilitates the installation and removal of the plug-in board. The structure is simple and easy to implement.

[0031] In one embodiment of this application, the drying chamber is provided with a fixed guide rod, and a U-shaped limiting frame that can open or lock the first handle is slidably connected to the fixed guide rod. A compression spring is sleeved on the fixed guide rod, and a limiting block is provided at the free end of the guide rod. The first end of the compression spring abuts against the U-shaped limiting frame, and the second end of the compression spring abuts against the limiting block. When the U-shaped limiting frame is in its natural state, the free end of the U-shaped limiting frame is inserted into the first handle.

[0032] By using a combination of a fixed guide rod, a U-shaped limiting frame, a compression spring, a limiting block, and a first handle, a stable and flexible locking mechanism is provided. The design of the fixed guide rod allows the U-shaped limiting frame to move smoothly up and down, while the counterforce of the compression spring ensures that the U-shaped limiting frame remains locked in its natural state, providing a high degree of safety.

[0033] In one embodiment of this application, the U-shaped limiting frame is provided with a second handle. Providing a second handle on the U-shaped limiting frame facilitates movement of the U-shaped limiting frame.

[0034] In one embodiment of this application, two circulating heating components are respectively located above and below the drying station to achieve simultaneous drying of both surfaces of the workpiece. By setting two circulating heating components, one above and one below the drying station, both sides of the workpiece can be heated simultaneously, ensuring the comprehensiveness and uniformity of the drying process. This greatly improves drying efficiency, allowing heat transfer to both sides of the workpiece synchronously and avoiding the uneven drying problem caused by heating only one side.

[0035] Using the above technical solution, the circulating heating component generates stable and continuous heat. Through its cooperation with the inner wall of the drying chamber, it forms an effective circulating air duct, allowing heat to circulate continuously and be evenly distributed within the chamber. This ensures that moisture on the surface of the parts to be dried evaporates quickly, avoiding the uneven heat distribution or localized overheating problems of traditional heating methods, and significantly improving drying efficiency. The adsorption component within the circulating air duct effectively removes moisture from the air, keeping the airflow dry and preventing the re-accumulation of moisture. This not only improves the drying effect but also reduces energy waste and the negative impact of moisture on drying efficiency. Attached Figure Description

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0045] like Figures 1 to 6 As shown, in order to achieve the above objectives, this utility model proposes a lithium battery coating and drying oven, comprising:

[0046] The drying oven body 1 has a drying station 6 inside that allows the parts to be dried 3 to pass through;

[0047] At least one circulating heating component is disposed within the drying chamber body 1, capable of generating heat, and cooperates with the inner wall of the drying chamber body 1 to form a circulating air duct, so as to circulate and guide the generated heat to the surface of the workpiece 3 to be dried; and

[0048] An adsorption component is disposed within the circulating air duct and is used to dry the gas within the circulating air duct.

[0049] Specifically, the drying chamber body 1 is a closed chamber with a drying station 6 for drying the parts 3 to be dried. The drying chamber body 1 has an inlet 2 for the parts to be dried and an outlet 3 for the parts to be dried, so that the parts 3 can enter the drying station 6. A circulating heating component is connected to the inner wall of the drying chamber body 1. The circulating heating system and the inner wall of the drying chamber work together to form a closed heat circulation system, ensuring effective heat conduction and airflow circulation.

[0050] The circulating heating component is located inside the drying chamber body 1, in an area close to the drying station 6. The main function of the circulating heating component is to generate heat to heat the workpiece 3 to be dried. The heating element in the circulating heating component can be in the form of heating wires, heating tubes, etc. To achieve air circulation, multiple partitions can be installed, with fixed vertical partitions 5 cooperating with the inner wall of the drying chamber body 1 to form a circulating air duct. A corresponding heating fan 10 is installed within the circulating air duct, blowing the heat generated by the heating element onto the workpiece 3 to be dried at the drying station 6, thereby uniformly heating the surface of the workpiece 3. The design of the circulating air duct ensures the circulation of hot air within the drying chamber body 1, thereby improving drying efficiency and ensuring effective removal of moisture from the surface of the coating material.

[0051] The adsorption assembly is installed within the circulating air duct of the drying chamber body 1, primarily for drying the gas within the duct. The main structure of the adsorption assembly includes moisture-absorbing materials (such as absorbent cotton, activated carbon filter plate 19, etc.), which effectively adsorb moisture and other harmful substances within the circulating air duct, ensuring air dryness and improving the drying effect. The adsorption assembly is connected to the circulating air duct via a fixed structure. When hot air flows through the circulating air duct, the adsorption assembly absorbs moisture from the air, keeping it dry and thus accelerating the drying process of the items 3 to be dried.

[0052] Using the above technical solution, the circulating heating component can generate stable and continuous heat. Through its cooperation with the inner wall of the drying chamber body 1, it forms an effective circulating air duct, allowing heat to circulate continuously and be evenly distributed within the chamber. This ensures that moisture on the surface of the workpiece 3 to be dried is quickly evaporated, avoiding the uneven heat distribution or localized overheating problems of traditional heating methods, and significantly improving drying efficiency. The adsorption component within the circulating air duct effectively removes moisture from the air, keeping the airflow dry and preventing the re-accumulation of moisture. This not only improves the drying effect but also reduces energy waste and the negative impact of moisture on drying efficiency.

[0053] In one embodiment of this application, the circulating heating assembly includes:

[0054] A fixed horizontal partition 4 is connected to the drying chamber body 1 to form a circulation space inside the drying chamber. The fixed horizontal partition 4 is provided with through holes 8 and circulation holes, and the working surface of the fixed horizontal partition 4 faces the drying station 6.

[0055] A heating element 9 is disposed within the through hole 8 to generate heat, and a gap is left between the heating element 9 and the through hole 8;

[0056] A heating fan 10, located within the circulation space, is used to guide the heat generated by the heating element 9 to the drying station 6; and

[0057] A circulating fan 11 is located inside the circulation hole and is used to guide the airflow passing through the drying station 6 into the circulation space. The adsorption element is located at the air outlet of the circulating fan 11.

[0058] Specifically, the fixed horizontal partition 4 is located inside the drying chamber body 1, forming a circulation space within the drying chamber. The fixed horizontal partition 4 is connected to the inner wall of the drying chamber body 1, with its working surface facing the drying station 6 to ensure effective heat transfer to the workpiece 3 to be dried. The fixed horizontal partition 4 has through holes 8 and circulation holes. The through holes 8 are used to install the heating element 9, while the circulation holes are used to install the circulating fan 11, allowing airflow to circulate effectively within the drying chamber. The fixed horizontal partition 4 is connected to the drying chamber body 1 by bolts or snap-fit ​​connections to maintain the structural stability of the entire circulating heating assembly.

[0059] The heating element 9 is located within the through hole 8 on the fixed transverse partition 4 and is primarily used to generate heat. The heating element 9 can be an electric heating wire, heating tube, or electric heating element, etc., which generates stable heat when current passes through it. A gap is left between the heating element 9 and the through hole 8. The heating element 9 and the fixed transverse partition 4 are connected in a detachable manner, such as by screws or bolts. This detachable connection facilitates the installation and removal of the heating element 9 and enables later maintenance. Of course, depending on design requirements, the heating element 9 can also be connected in a fixed manner, such as by integral molding or welding. A fixed connection improves the connection strength between the heating element 9 and the fixed transverse partition 4.

[0060] The heating fan 10 is located in the circulation space inside the drying chamber body 1, and is responsible for guiding the heat generated by the heating element 9 to the drying station 6. The heating fan 10 is an axial flow fan or a centrifugal fan, and is connected to the heating element 9 through pipes or air ducts. When the heating element 9 generates heat, the heating fan 10 delivers the heated air to the drying station 6, ensuring that the surface of the item 3 to be dried can receive heat evenly, thereby accelerating the evaporation of moisture.

[0061] The circulating fan 11 is located in the circulation hole on the fixed horizontal partition 4. Its main function is to guide the airflow passing through the drying station 6 into the circulation space and bring the airflow back to the heating area for reheating. Through the action of the circulating fan 11, the airflow carries away moisture as it passes through the drying station 6 and continues to circulate within the circulation space, accelerating the drying process. The adsorption component is located at the air outlet of the circulating fan 11 and is mainly used to adsorb and remove moisture from the airflow passing through the drying station 6. The adsorption component may include moisture-absorbing materials (such as absorbent cotton, activated carbon filter plate 19, etc.) and other devices for filtering moisture and impurities from the airflow.

[0062] Using the above technical solution, the heating element 9 directly heats the air with the heat it generates, and then the heated air is effectively transported to the drying station 6 by the heating fan 10, ensuring uniform heat distribution and improving the drying effect. The circulating fan 11 guides the airflow to circulate within the drying chamber, allowing the hot air to pass through the drying station 6 multiple times, further improving heat utilization efficiency. Through the action of the adsorption component, moisture in the air is effectively removed, keeping the airflow inside the drying chamber dry and avoiding the impact of moisture on drying efficiency. This effectively improves the energy utilization efficiency of the drying process, reduces heat waste, and accelerates the drying speed of the coating material.

[0063] In one embodiment of this application, the circulating heating assembly further includes:

[0064] A fixed vertical partition 5 is vertically connected to the fixed horizontal partition 4 and located between the through hole 8 and the circulation hole, used to divide the circulation space into an inner circulation space and an outer circulation space 7. The fixed vertical partition 5 is provided with a connecting hole 12 to conduct the inner circulation space and the outer circulation space 7; the adsorption component is located in the outer circulation space 7.

[0065] Specifically, the fixed vertical partition 5 is vertically connected to the fixed horizontal partition 4 and is located between the through hole 8 and the circulation hole. Its main function is to divide the circulation space into an inner circulation space and an outer circulation space 7, thereby allowing for more precise control of the airflow inside the drying oven. The fixed vertical partition 5 is fixed to the fixed horizontal partition 4 by bolts or integral molding to ensure its stability. The fixed vertical partition 5 is provided with a connecting hole 12, which can conduct air between the inner circulation space and the outer circulation space 7. This ensures that the airflow can flow freely between the two spaces without affecting the uniformity and flow efficiency of the hot airflow. The size and position of the connecting hole 12 can be adjusted according to specific airflow requirements to optimize the airflow path and heat distribution. The adsorption component is located inside the outer circulation space 7.

[0066] By adopting the above technical solution, the structure of the fixed vertical partition 5 introduced into the circulating heating component effectively divides the different areas of the circulating space, making the airflow inside the drying chamber more orderly and efficient. The fixed vertical partition 5 separates the inner circulating space and the outer circulating space 7, allowing the heating and moisture absorption processes to proceed independently. The adsorption component is located in the outer circulating space 7, which can effectively adsorb moisture from the hot air before it recirculates, thereby reducing the negative impact of moisture on the drying process and ensuring the continuity and stability of the drying process.

[0067] In one embodiment of this application, the circulating heating assembly further includes:

[0068] The guide plate 13 is connected to the fixed vertical partition 5 on the first side to form an air inlet channel in the circulation space, and the adsorption component can abut against the air inlet of the air inlet channel.

[0069] Specifically, the first side of the guide plate 13 is connected to the fixed vertical partition 5, forming an air inlet channel for the circulating inner space. The function of the guide plate 13 is to guide the flow direction of the airflow, ensuring that the airflow entering the circulating inner space can flow smoothly to the predetermined area. The adsorption component is set at the air inlet of the air inlet channel to ensure that all airflow entering the circulating inner space is treated with moisture absorption, thereby keeping the air dry and avoiding interference from moisture in the drying process.

[0070] By adopting the above technical solution, the baffle 13 ensures that the airflow direction is effectively guided, avoiding irregular airflow and helping hot air to smoothly enter the circulation space. This improves the utilization efficiency of the hot airflow and avoids heat waste. The adsorption component is located at the air inlet, ensuring that the airflow entering the circulation space is fully dried before recirculation, thereby avoiding moisture accumulation and maintaining the drying efficiency of the airflow.

[0071] In one embodiment of this application, the adsorption component includes:

[0072] The plug-in plate 16, the drying oven body 1 is provided with a plug-in interface 14 for inserting or removing the plug-in plate 16, and the plug-in plate 16 is provided with a mounting through hole 17; and

[0073] Moisture-absorbing cotton 18 is disposed within the mounting through hole 17.

[0074] Specifically, the plug-in plate 16 is installed in the plug-in interface 14 of the drying chamber body 1, and the mounting through hole 17 of the plug-in plate 16 is used to fix the moisture-absorbing cotton 18. The plug-in plate 16 is connected to the plug-in interface 14 of the drying chamber body 1 by a sliding plug-in connection, and the plug-in plate 16 can be easily installed or removed by inserting or pulling it out. The moisture-absorbing cotton 18 is made of a material with strong moisture absorption function, such as high-efficiency moisture-absorbing fibers or moisture-absorbing materials, which can quickly absorb and store moisture and keep the airflow dry. The replacement of the moisture-absorbing cotton 18 can be completed by inserting or removing the plug-in plate 16, which makes maintenance and replacement more convenient.

[0075] By adopting the above technical solution and designing the adsorption component as pluggable, the replacement and maintenance of the entire moisture-absorbing cotton 18 is made simpler and more efficient, ensuring the effectiveness of its moisture-absorbing function.

[0076] In one embodiment of this application, the adsorption assembly further includes an activated carbon filter plate 19 disposed within the mounting through hole 17 and stacked with the moisture-absorbing cotton 18.

[0077] Specifically, the activated carbon filter plate 19 is installed within the mounting through-hole 17 of the plug-in plate 16. The activated carbon filter plate 19 is used to filter harmful gases, odors, and some fine pollutants from the air, thus purifying the air. The activated carbon filter plate 19 is made of activated carbon material with strong adsorption properties and can remove harmful substances from the air through physical and chemical adsorption. The layered structure of the activated carbon filter plate 19 and the moisture-absorbing cotton 18 further enhances the filtration effect of both.

[0078] By adopting the above technical solution, the activated carbon filter plate 19 and the moisture-absorbing cotton 18 are stacked to form a dual purification and moisture-absorbing structure, which significantly improves the air purification and drying effect.

[0079] In one embodiment of this application, the plug-in plate 16 is provided with a first handle 20.

[0080] By adopting the above technical solution, a first handle 20 is provided on the plug-in plate 16 to facilitate the installation and removal of the plug-in plate 16. The structure is simple and easy to implement.

[0081] In one embodiment of this application, the drying chamber is provided with a fixed guide rod 22, and a U-shaped limiting frame 21 that can open or lock the first handle 20 is slidably connected to the fixed guide rod 22. A compression spring 24 is sleeved on the fixed guide rod 22, and a limiting block 23 is provided at the free end of the guide rod. The first end of the compression spring 24 abuts against the U-shaped limiting frame 21, and the second end of the compression spring 24 abuts against the limiting block 23. When the U-shaped limiting frame 21 is in its natural state, the free end of the U-shaped limiting frame 21 is inserted into the first handle 20.

[0082] Specifically, the fixed guide rod 22 is installed on the drying chamber and connected to the drying chamber by a fixing structure such as bolts or screws. The main function of the fixed guide rod 22 is to provide sliding guidance for the U-shaped limiting frame 21, ensuring that the U-shaped limiting frame 21 slides smoothly within the predetermined track. To ensure the stable sliding of the U-shaped limiting frame 21, the number of fixed guide rods 22 is preferably two or more to support the stable movement of the U-shaped limiting frame 21.

[0083] The U-shaped limiting frame 21 is slidably connected to the fixed guide rod 22 and can slide along the fixed guide rod 22. The U-shaped limiting frame 21 is used to cooperate with the first handle 20 to perform the opening or locking function.

[0084] A compression spring 24 is sleeved on the fixed guide rod 22, with one end abutting against the U-shaped limiting frame 21 and the other end abutting against the limiting block 23. The compression spring 24, through its elastic action, holds the U-shaped limiting frame 21 in a predetermined position, providing a certain degree of elastic support and resistance. When the U-shaped limiting frame 21 is in its natural state, the spring's counterforce ensures that the U-shaped limiting frame 21 can be freely inserted into the first handle 20, providing a locking function.

[0085] By employing the above technical solution, a stable and flexible locking mechanism is provided through the combination of a fixed guide rod 22, a U-shaped limiting frame 21, a compression spring 24, a limiting block 23, and a first handle 20. The design of the fixed guide rod 22 allows the U-shaped limiting frame 21 to move smoothly up and down, while the counterforce of the compression spring 24 ensures that the U-shaped limiting frame 21 remains locked in its natural state, providing a high degree of safety.

[0086] In one embodiment of this application, the U-shaped limiting frame 21 is provided with a second handle 25.

[0087] By adopting the above technical solution, a second handle 25 is provided on the U-shaped limiting frame 21 to facilitate the movement of the U-shaped limiting frame 21.

[0088] In one embodiment of this application, there are two circulating heating components, located above and below the drying station 6, respectively, so as to achieve simultaneous drying of the two surfaces of the workpiece 3 to be dried.

[0089] By adopting the above technical solution, two circulating heating components are set up, one above and one below the drying station 6, respectively, so that both sides of the part to be dried 3 can be heated simultaneously, ensuring the comprehensiveness and uniformity of the drying process. This greatly improves the drying efficiency, allowing heat to be transferred to both sides of the part to be dried 3 at the same time, avoiding the uneven drying problem caused by heating only one side.
