Description

Technical Field

[0001] This utility model relates to the field of coating and drying technology, specifically a coating and drying device that can utilize waste heat circulation for drying. Background Technology

[0002] In the manufacturing process of lithium-ion battery electrodes, a liquid slurry needs to be uniformly coated onto aluminum or copper foil, followed by continuous high-temperature baking to evaporate the solvent in the slurry, forming the finished battery electrode solidified on the substrate. The drying process is crucial, as its drying speed directly affects the operating efficiency of the coating equipment.

[0003] Authorization notice number CN213558172U provides a coating drying device, which includes a drying chamber with an inlet for the metal substrate to enter and an outlet for the metal substrate to exit. A conveying path for the metal substrate is formed between the inlet and outlet. An electromagnetic coil for generating a magnetic field is installed inside the drying chamber, and the conveying path passes through the magnetic field. This coating drying device causes the metal substrate to heat up naturally, allowing the slurry on the surface of the metal substrate to dry from the inside out. This effectively prevents the formation of a hard film on the slurry surface, ensures the smooth evaporation of solvents inside the slurry, and improves drying efficiency and coating quality. It is highly efficient and energy-saving, using internal heating, resulting in very fast start-up and significantly improving coating production efficiency.

[0004] The existing technical solutions described above have the following drawbacks: existing coating drying devices do not facilitate the recycling of waste heat generated during use, resulting in excessive energy consumption when drying the slurry, which greatly increases the processing cost of the device. At the same time, it is not convenient to filter the intake air during use, causing dust to easily enter the device and adhere to the slurry surface, reducing the processing quality of the device. Therefore, this utility model provides a coating drying device that can utilize waste heat for recycling and drying, in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a coating drying device that can utilize waste heat for drying, in order to solve the problems mentioned in the background art, such as the inconvenience of recycling the waste heat generated by the device during use, which leads to excessive energy consumption when drying the slurry, resulting in a significant increase in the processing cost of the device, and the inconvenience of dust filtration of the intake air during use, which causes dust to easily enter the device and adhere to the slurry surface, reducing the processing quality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating drying device that can utilize waste heat circulation for drying, comprising: a base, and a drying chamber disposed on the upper side of the base, and further comprising:

[0007] A first drive motor is mounted on the right rear end of the base, and a first drive rod is connected to the front of the first drive motor. A conveyor belt is connected to the left side of the first drive rod, and a second drive rod is located on the left side of the conveyor belt. A filter assembly is located on the upper side of the drying chamber, and a second support frame is located at the lower end of the filter assembly. A support block is located on the upper side of the second support frame, and a second drive motor is located on the outer side of the support block. Fan blades are located on the outer side of the support block. A support plate is located at the lower end of the second support frame, and a limit rod is located at the lower end of the support plate. A heating tube is located on the upper side of the support plate, and a bracket is located at the lower end of the heating tube. An air nozzle is located on the outer side of the support plate, and a heat spreader is located on the inner side of the conveyor belt.

[0008] In one possible implementation, the filter assembly includes a first support frame mounted on the upper side of the drying chamber, with a connecting block provided on the outer side of the first support frame and a filter screen provided on the inner side of the first support frame.

[0009] In one possible implementation, the connecting block is engaged with the drying box, and the cross-section of the connecting block is a "T" shaped structure.

[0010] In one possible implementation, the fan blades are engaged with the support block, and the fan blades are symmetrically arranged about the central axis of the support block.

[0011] In one possible implementation, the heating tube has a wavy cross-section, and the bracket is engaged with the heating tube.

[0012] In one possible implementation, the limiting rod is threadedly connected to both the support plate and the drying box, and the limiting rod is symmetrically arranged about the central axis of the support plate.

[0013] In one possible implementation, the drying oven has a third support frame inside, a positioning rod on the outside of the third support frame, fins inside the third support frame, and a heat-conducting copper pipe at the lower end of the third support frame.

[0014] In one possible implementation, the third support frame is engaged with the positioning rod, and the third support frame is symmetrically arranged about the central axis of the drying box.

[0015] In one possible implementation, the fins are arranged at equal intervals inside the third support frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This coating drying device that utilizes waste heat circulation for drying facilitates the recycling of waste heat generated during use, reducing energy consumption during slurry drying and lowering processing costs. Simultaneously, it facilitates dust filtration of the intake air, preventing dust from easily entering the device and adhering to the slurry surface, thus improving processing quality and resulting in better performance. Specific details are as follows:

[0017] The filter screen is fixed to the upper side of the drying box by the first support frame and connecting block, so that the filter screen can filter the dust and impurities in the intake air, prevent the dust and impurities from entering the interior of the drying box, and improve the drying quality of the device.

[0018] By using a limiting rod in conjunction with the drying box, the support plate and heating tube are fixed to the upper side of the drying box, so that the heating tube heats the air that is drawn in, while the support plate blocks the air and discharges it into the interior of the drying box through the air nozzle. This prevents the heated air from blowing directly onto the raw materials, reduces cracking caused by uneven heating, and improves the processing quality of the device.

[0019] The waste heat generated by the heated air is collected by the third support frame and fins, so that the heat is conducted into the interior of the heat spreader through the heat-conducting copper pipe. The heat spreader then heats and dries the raw material on the conveyor belt, reducing the energy consumption of the device and reducing processing costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a coating drying device that can utilize waste heat circulation for drying, comprising: a base 1, and a drying chamber 6 disposed on the upper side of the base 1, and further comprising:

[0028] The first drive motor 2 is installed at the rear right side of the base 1, and the front side of the first drive motor 2 is connected to the first drive rod 3. The left side of the first drive rod 3 is connected to the conveyor belt 4, and the left side of the conveyor belt 4 is provided with the second drive rod 5. The upper side of the drying box 6 is provided with the filter assembly 7, and the lower end of the filter assembly 7 is provided with the second support frame 8. The upper side of the second support frame 8 is provided with the support block 9, and the outer side of the support block 9 is provided with the second drive motor 10. The outer side of the support block 9 is provided with the fan blade 11. The lower end of the second support frame 8 is provided with the support plate 12, and the lower end of the support plate 12 is provided with the limit rod 13. The upper side of the support plate 12 is provided with the heating tube 14, and the lower end of the heating tube 14 is provided with the bracket 15. The outer side of the support plate 12 is provided with the air nozzle 16. The inner side of the conveyor belt 4 is provided with the heat spreader 21, which constitutes a complete coating and drying device.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, the filter assembly 7 includes a first support frame 701 mounted on the upper side of the drying chamber 6, with a connecting block 702 on the outer side of the first support frame 701 and a filter screen 703 on the inner side of the first support frame 701. The connecting block 702 is engaged with the drying chamber 6, and the cross-section of the connecting block 702 is a "T" shaped structure. The fan blade 11 is engaged with the support block 9, and the fan blade 11 is symmetrically arranged about the central axis of the support block 9. The first drive motor 2 drives the first drive rod 3 to rotate on the right side of the base 1, causing the first drive rod 3 to push the conveyor belt 4 along the second drive... As rod 5 rotates, the raw material is displaced to the left by conveyor belt 4 and enters the interior of drying chamber 6. At the same time, the second drive motor 10 drives the support block 9 to rotate along the second support frame 8, so that the support block 9 drives the fan blades 11 to draw air from outside the drying chamber 6 into the interior of the drying chamber 6 from the top side. At this time, the first support frame 701 is installed on the top side of the drying chamber 6 along the connecting block 702, so that the filter screen 703 set on the inner side of the first support frame 701 filters the dust and impurities in the drawn-in air, preventing dust and impurities from entering the interior of the drying chamber 6 and improving the drying processing quality of the device.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the heating tube 14 has a corrugated cross-section, and the bracket 15 is engaged with the heating tube 14. The limiting rod 13 is threadedly connected to the support plate 12 and the drying box 6. The limiting rod 13 is symmetrically arranged about the central axis of the support plate 12. By installing the support plate 12 inside the drying box 6 and rotating the limiting rod 13, the limiting rod 13 connects the support plate 12 and the drying box 6 to fix the heating tube 14 inside the drying box 6. The heating tube 14 heats the intake air, while the support plate 12 blocks the intake air, so that the heated air is discharged into the drying box 6 through the air nozzle 16. This prevents the heated air from directly blowing on the raw material, making the raw material less prone to uneven heating and cracking, and improving the processing quality of the device.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a third support frame 17 is provided inside the drying chamber 6, and a positioning rod 18 is provided on the outside of the third support frame 17.

The third support frame 17 and the positioning rod 18 are engaged with each other, and the third support frame 17 is symmetrically arranged about the central axis of the drying chamber 6. The fins 19 are evenly spaced inside the third support frame 17. The waste heat generated by the heated air is collected through the third support frame 17 and the fins 19 inside it. At this time, the heat is conducted into the interior of the heat spreader 21 through the heat-conducting copper pipe 20, so that the heat spreader 21 performs secondary heating and drying on the raw materials on the upper side of the conveyor belt 4, thereby reducing the energy consumption of the device and reducing the processing cost.
