Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a drying device for preparing a non-metallic material dispersant for lithium batteries. Background Art

[0002] During the production process of dispersants for non-metallic materials in lithium batteries, the materials often need to be treated with solvents or moisture. These solvents or moisture must be removed to avoid affecting the performance of the dispersant. The drying device ensures that the material reaches the required dry state before final use through heating and dehumidification, thereby improving its dispersion performance and stability. Existing drying devices usually do not preheat the materials during use, and directly put the materials into the drying box. Due to the high temperature of the drying box, the sudden high temperature can easily cause the surface of the material to dry quickly, thereby forming a drying shell, making it difficult to discharge the moisture inside the material, affecting the drying effect. In addition, the sudden heating of the material at high temperature may cause thermal stress, causing the material to deform or crack. Utility Model Content

[0005] Furthermore, at least two mesh box drawers evenly distributed in the longitudinal direction are slidably installed inside the drying box, and desiccant particles are added inside the mesh box drawers.

[0006] Furthermore, an air collecting frame is fixedly installed on the other side of the inner wall of the drying box, and the air collecting frame is arranged in a trapezoidal shape.

[0007] Furthermore, an electric push rod is fixedly installed at one end of the drying box, and the free end of the electric push rod extends to the interior of the drying box and is fixedly connected to a bulk plate.

[0008] Furthermore, a plurality of material distribution grooves are provided inside the bulk material plate, and the inner bottom walls of the material distribution grooves are provided with pointed protrusions.

[0009] Furthermore, a cover plate is slidably installed on the top of the drying box, and a handle is provided on the cover plate.

[0010] Furthermore, a feed cover is movably mounted on one end of the preheating cylinder away from the bracket, a discharge port is provided at the bottom of the preheating cylinder, and an insulation sleeve is provided on the outside of the preheating cylinder.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Existing drying devices usually do not preheat the materials when in use, and directly put the materials into the drying box. Due to the high temperature of the drying box, the sudden high temperature can easily cause the surface of the material to dry quickly, thereby forming a drying shell, making it difficult to drain the moisture inside the material, affecting the drying effect. In addition, the sudden heating of the material at high temperature may cause thermal stress, causing the material to deform or crack.

[0025] To solve the defects of the above drying device during use, please refer to Figure 1-Figure 5The utility model provides a drying device for preparing a non-metallic material dispersant for lithium batteries, which can use the heat in a drying box 1 to preheat the material and then dry the material, gradually reducing the temperature difference of the material and reducing the risk of material deformation. The drying device is based on a drying box 1. A hot air blower 2 is fixedly installed on one side of the drying box 1. A hot air panel 3 is installed at the output end of the hot air blower 2. The hot air panel 3 is fixedly installed on one side of the inner wall of the drying box 1. A plurality of evenly distributed air outlets are provided on the hot air panel 3. When the material is added to the drying box 1, the hot air blower 2 is driven to evenly deliver hot air to the drying box 1. The hot air can dry the material in the drying box 1. A bracket 11 is symmetrically installed on the other side of the drying box 1. A preheating cylinder 4 is commonly installed on the upper ends of the two brackets 11. Before the material enters the drying box 1, it is first placed in the preheating cylinder 4 for preheating. A heat conduction mechanism 5 is provided between the drying box 1 and the preheating cylinder 4. The heat conduction mechanism 5 can recover the heat in the drying box 1 and conduct it to the heat exchanger. The hot air can flow into the preheating cylinder 4 through the air supply pipe 51, thereby increasing the temperature inside the preheating cylinder 4. After the hot air cools the material, the temperature of the material entering the preheating cylinder 4 is lower than the temperature in the drying box 1. The material can be preheated in the preheating cylinder 4, thereby achieving a gradual drying effect, thereby avoiding agglomeration of the material surface caused by a sudden increase in temperature, and achieving a better and more uniform drying effect.

[0026] Since the hot air blown out by the hot air panel 3 passes through the surface of the material and can take away the moisture on the material, the hot air with water vapor directly entering the preheating cylinder 4 will make the air in the preheating cylinder 4 more humid, which is not conducive to the preheating of the material. In order to solve this technical problem, at least two mesh box drawers 53 with uniform longitudinal distribution are slidably installed inside the drying box 52. Desiccant particles are added to the inside of the mesh box drawer 53. The desiccant particles can absorb water vapor in the hot air and improve the dryness of the gas. The staff can take out the mesh box drawer 53 regularly to replace the desiccant.

[0027] Since the air supply pipe 51 is connected to the interior of the drying box 1, in order to prevent the material in the drying box 1 from accidentally entering the air supply pipe 51, an air collecting frame 9 is fixedly installed on the other side of the inner wall of the drying box 1. The air collecting frame 9 is arranged to be trapezoidal. The height of the material added to the drying box 1 each time does not exceed the air collecting frame 9. The air collecting frame 9 can block the material without affecting the circulation of hot air. The trapezoidal air collecting frame 9 can expand the range of hot air collection.

[0028] In order to speed up the drying of the material, an electric push rod 6 is fixedly installed at one end of the drying box 1. The free end of the electric push rod 6 extends to the inside of the drying box 1 and is fixedly connected to a bulk plate 7. A plurality of dividing grooves 8 are provided inside the bulk plate 7. The inner bottom wall of the dividing groove 8 is provided with a pointed protrusion. Driving the electric push rod 6 can drive the bulk plate 7 to move back and forth. The setting of the dividing groove 8 can disrupt the position of the material and make the material evenly heated. The pointed protrusion on the inner bottom wall of the dividing groove 8 can prevent the material from accumulating in the dividing groove 8.

[0029] In order to prevent the heat in the drying box 1 from being lost, a cover plate 10 is slidably installed on the top of the drying box 1. A handle is provided on the cover plate 10, and the cover plate 10 can close the drying box 1.

[0030] After the material is preheated in the preheating cylinder 4, in order to facilitate the direct introduction of the material into the drying box 1 for drying, a feed cover 13 is movably installed at the end of the preheating cylinder 4 away from the bracket 11, and a discharge port 12 is provided at the bottom of the preheating cylinder 4. A discharge door corresponding to the discharge port 12 is hinged on the preheating cylinder 4. The discharge port 12 is set above the drying box 1. After opening the discharge door and the cover 10, the material can fall directly into the drying box 1 from the discharge port 12, and the outer sleeve of the preheating cylinder 4 is provided with an insulation sleeve, which can reduce the heat loss in the preheating cylinder 4.

[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0032] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
