Description

Technical Field

[0001] The utility model relates to the technical field of solid electrolyte drying equipment, in particular to a drying device for solid electrolyte production. Background Art

[0002] Solid-state electrolytes (SSEs) are solid ion conductor electrolytes that can be used in electrical energy storage (EES). Their main advantages are increased safety, no leakage of toxic organic liquids, low flammability, non-volatility, mechanical and thermal stability, easy processability, low self-discharge rate, higher achievable power density and cyclability.

[0003] In the production of solid electrolytes, solid electrolyte materials are generally dried by microwave vacuum dryers. Vacuum microwave dryers use microwave energy to heat in a vacuum environment to generate heat inside the wet material to evaporate the material. Its main working principle is:

[0004] The wet material is placed in a vacuum chamber, the pressure in the vacuum chamber is reduced to a certain level, and then microwave energy is transmitted into the vacuum chamber through a microwave generator. The rapid rotation and friction inside the wet material generate heat, causing the water inside the wet material to evaporate rapidly. Finally, the water vapor is discharged through a vacuum pump under a vacuum environment;

[0005] There is a vacuum microwave drying machine, in which a rotating disk and a material tray bracket hingedly connected to the rotating disk are arranged inside, the material tray is placed on the material tray bracket, and the rotating disk is rotated to make the material in the material tray rotate in the drying furnace for heating, so that the material is heated more evenly;

[0006] However, when this type of vacuum microwave dryer is actually used, when placing the material trays on the material tray bracket in turn, the material tray bracket needs to repeat the process of rotating and stopping many times. During this process, the material tray bracket will shake during the transition between the start and stop states, which may cause the solid electrolyte material in the material tray to easily spill out. In order to avoid this situation, a drying device for solid electrolyte production is provided. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 3 In an embodiment of the utility model, a drying device for solid electrolyte production includes a vacuum microwave dryer 1 composed of a drying box body 101, a fixed guide rail 102, an outer support frame 103, a mobile frame 104, a rotating disk 105, and a hanging rod 106. The fixed guide rail 102 is symmetrically fixedly installed at the bottom of the inner side of the drying box body 101, the outer support frame 103 is placed at the front end of the drying box body 101, the mobile frame 104 is slidably installed on the top of the outer support frame 103, the rotating disk 105 is rotatably installed on the inner side of the mobile frame 104, and a plurality of hanging rods 106 are provided. The plurality of hanging rods 106 are evenly distributed along the annular edge of the rotating disk 105 and are fixedly connected to the rotating disk 105. The outer side of the hanging rod 106 is sleeved with a material support assembly 2, and the material support assembly 2 is used to provide a placement space for a material tray containing solid electrolyte materials;

[0031] The material holding bracket assembly 2 includes a support unit and an anti-sway unit. The support unit is connected to the hanging rod 106 to provide a placement space for the material tray. The anti-sway unit is used to increase the mutual friction between the support unit and the hanging rod 106 to prevent the support unit from shaking.

[0032] The supporting unit includes a triangular mounting frame 201 and an inclined hook slot 202;

[0033] The side cross section of the triangular hanging frame 201 is a triangular structure, and the inclined hook groove 202 is opened at the top of the triangular structure of the triangular hanging frame 201 and passes through one end of the triangular hanging frame 201. The triangular hanging frame 201 is hung on the outside of the hanging rod 106 through the inclined hook groove 202. The bottom of the triangular hanging frame 201 is formed with a groove for placing the material tray;

[0034] The anti-sway unit includes a resistance ball 203, a contraction groove 204, and a compression spring 205;

[0035] The outer side of the hanging rod 106 is formed with a plurality of evenly distributed annular positioning grooves 107;

[0036] The resistance ball 203 is disposed on the inner side of the triangular mounting frame 201 and protrudes to the inner side of the inclined hook groove 202. The resistance ball 203 is engaged with a positioning groove 107.

[0037] The contraction groove 204 is provided inside the triangular mounting frame 201 at a position in contact with the resistance ball 203, and the contraction groove 204 is used to provide space for the contraction of the resistance ball 203;

[0038] The compression spring 205 is distributed inside the contraction groove 204 and fits with one end of the resistance ball 203 to provide thrust for the resistance ball 203;

[0039] When the rotating disk 105 rotates in a circle, the triangular mounting frame 201 maintains its verticality unchanged under the action of its own weight and the weight of the material disk and the material, and the rotating disk 105 rotates relative to the triangular mounting frame 201, and the resistance ball 203 cooperates with the positioning groove 107 to provide resistance to the relative rotation of the rotating disk 105 and the triangular mounting frame 201, and when the relative movement stops, it is used to slow down the shaking tendency of the triangular mounting frame 201;

[0040] The contraction groove 204 is inclined, and the inclination direction of the contraction groove 204 is toward the rotation direction of the rotating disk 105 relative to the triangular mounting frame 201. When the triangular mounting frame 201 rotates oppositely relative to the rotating disk 105, the resistance ball 203 provides greater rotation resistance.

[0041] In this embodiment, it should be supplemented that: the outer support frame 103 is provided with a guide rail aligned with the fixed guide rail 102, and the mobile frame 104 can move along the fixed guide rail 102 and the top of the outer support frame 103, so that the rotating disk 105 can be moved into or out of the drying box body 101, which is convenient for loading and unloading operations. In addition, a driving component for driving the rotating disk 105 to rotate is provided inside the drying box body 101, and the rotating disk 105 can drive the material to perform a circular motion, so that the material is dried more evenly. The driving component and the heating structure inside the drying box body 101 are existing structures, so they are not described in detail.

[0042] The triangular hanging frame 201 is hung on the outside of the hanging rod 106 through the inclined hook groove 202. When the rotating plate 105 drives the hanging rod 106 to perform circular motion, the triangular hanging frame 201 can maintain a vertical state under the action of its own gravity, so that the opening of the material tray placed on the inner side of the bottom of the triangular hanging frame 201 is always facing upward, thus ensuring the stability of the material loading;

[0043] During the feeding process, the material-containing trays need to be placed inside each triangular hanging frame 201 in sequence. During this process, the rotating disk 105 needs to be manually rotated to rotate the empty triangular hanging frames 201 to the feeding position one by one. When the rotating disk 105 rotates, since the triangular hanging frames 201 remain in a vertical state, the hanging rod 106 will rotate relative to the triangular hanging frames 201, and the hanging rod 106 will squeeze the resistance ball 203 through the positioning groove 107, so that the resistance ball 203 shrinks into the inside of the shrinkage groove 204 and further squeezes and deforms the compression spring 205. When another positioning groove 107 is aligned with the resistance ball 203, the resistance ball 203 will be reset and stuck into the inside of another positioning groove 107 under the elastic force of the compression spring 205, and so on.

[0044] During the contraction of the resistance ball 203, a reverse action is exerted on the hanging rod 106 and the triangular hanging frame 201. This reverse action can increase the relative rotation resistance between the hanging rod 106 and the triangular hanging frame 201. When the rotating disk 105 stops, the hanging rod 106 does not move, and the triangular hanging frame 201 rotates relative to the hanging rod 106 under the action of inertia. At this time, the rotation resistance exerted by the resistance ball 203 can slow down the rotation inertia of the triangular hanging frame 201, reduce the shaking tendency of the triangular hanging frame 201, keep the triangular hanging frame 201 in a non-shaking state or make the triangular hanging frame 201 deflect by a small angle.

[0045] When the inertia of the triangular mounting frame 201 is greater than the rotation resistance given by the resistance ball 203 and a small angle deflection occurs, the triangular mounting frame 201 will have a tendency to return to its original position under the action of gravity after the deflection. At this time, since the rotation direction of the triangular mounting frame 201 changes, the extrusion force on the resistance ball 203 is not directed toward the contraction groove 204, that is, the resistance ball 203 is not easy to contract, so that the resistance ball 203 gives a greater resistance to the triangular mounting frame 201, thereby further weakening the return kinetic energy of the triangular mounting frame 201, reducing the shaking amplitude of the triangular mounting frame 201, and being able to return to a stable vertical state more quickly;

[0046] The cooperation of the above multiple parts can effectively reduce the shaking amplitude of the triangular hanging frame 201. Compared with the traditional structure without buffer, the material tray in the triangular hanging frame 201 can be better maintained stable, thereby avoiding the situation where the material is scattered due to large shaking.

[0047] Please refer to Figure 3 There are multiple groups of resistance balls 203, contraction grooves 204, and compression springs 205 evenly arranged with the rotating disk 105 as the center. The multiple groups of resistance balls 203, contraction grooves 204, and compression springs 205 are evenly distributed on the inner side of the inclined hook groove 202 in an arc shape.

[0048] In this embodiment, the structural arrangement of multiple groups of resistance balls 203, contraction grooves 204, and compression springs 205 can provide sufficient buffer resistance for the triangular mounting frame 201, thereby achieving a better anti-swaying effect.

[0049] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
