Abstract
The invention discloses a drying box of a lithium battery cathode material. The outer part of the drying box is provided with a sealing box, a microwave device is arranged in the sealing box, the microwave device comprises a microwave generator, a magnetron and a magnetic field blender; the magnetic field blender is fixedly arranged on the top surface of the sealing box, the microwave generator is arranged above one side surface of the sealing box, one end of the microwave generator is fixedly connected with the magnetron, the magnetron is fixedly connected with the side surface of the sealing box; and the lithium battery cathode material absorbs little microwaves, the moisture can easily absorb microwaves, the energy is furthest focused on the moisture, the inner part and the outer part of the lithium battery cathode material are synchronously heated, so that the drying speed is improved greatly. The drying box of the lithium battery cathode material has the effect of energy saving.
Description
Technical field
The present invention relates to a kind of drying plant, particularly the negative material to lithium battery carries out dry drying baker.
Background technology
The oven dry principle that drying plant in the market is commonly used has mechanical evaporation, chemistry to remove these three kinds of wet method and heat drying methods.Wherein, the mechanical dehydration method be with material behind settling tank, filter, through squeezing and oven dry such as whizzer, this method can only be removed part Free water part in the material again, but combination moisture content still remains in the material.It is to utilize hygroscopic agent to remove the small amount of moisture in gas, liquid, the solid material that chemistry removes wet method, because the dehumidifying effect of hygroscopic agent is limited, therefore, can only remove the trace water in the material.The heat drying method mainly is to utilize heat energy to add thermal material; Moisture content in the gasification materiel; Like steam drying, far-infrared ray drying etc. all are to utilize heat conducting characteristic to be delivered to dry run of the inner formation of material to temperature, in this dry run; The skin of material is dried earlier, and then drying layer moves in gradually.The defective of above-mentioned three kinds of furnace drying methods is: mainly be moisture content and the partial interior moisture content of removing the material surface, can't remove whole combination moisture content of material inside.And being used to produce the negative material of lithium battery, it must have stable, high-quality electrical property and chemical property, when the negative material to lithium battery carries out drying, must reach the requirement of the low and uniformity of overall moisture content.Therefore, above-mentioned three kinds of furnace drying methods are not suitable for the oven dry to lithium cell cathode material.
Summary of the invention
The objective of the invention is provides a kind of lithium cell cathode material drying baker for overcoming the deficiency of above-mentioned prior art, can effectively remove the inside and outside moisture content of lithium cell cathode material, improves its electrical property and chemical property.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: the outside is a seal case, and microwave device is set in seal case, and this microwave device comprises microwave generator, magnetron and magnetic field agitator; The magnetic field agitator is fixedly installed on the end face of seal case; Above seal case one side, microwave generator is set, microwave generator one end is fixedly connected magnetron, magnetron fixed connection and sealing casing side.
The present invention adopts microwave drying technology, lithium ion battery negative material to the absorption of microwave seldom, and moisture content is easy to absorb microwave; Energy can concentrate on the moisture content to greatest extent, overcomes the many drawbacks in the common drying means, because microwave has very strong penetrability; When lithium cell cathode material ran into microwave, inside and outside can the heating simultaneously improved rate of drying greatly; Simultaneously, also has energy-saving effect.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.
Fig. 1 is a structural representation of the present invention:
Among the figure: 1. magnetic field agitator; 2. seal case; 3. microwave generator; 4. magnetron; 5. microwave; 6. oven dry table top.
The specific embodiment
Referring to Fig. 1, outside of the present invention is a seal case 2, and seal case 2 is provided with the anti-leak door; In seal case 2, microwave device is set, this microwave device comprises microwave generator 3, magnetron 4, magnetic field agitator 1, wherein; Magnetic field agitator 1 is fixedly mounted on the end face of seal case 2; And magnetic field agitator 1 its objective is the microwave in the seal case 2 is stirred to extending below suitable height, makes microwave even.Above a side of seal case 2, microwave generator 3 is set; Microwave generator 3 one ends are fixedly connected magnetron 4; Magnetron 4 is fixedly connected on seal case 2 sides, and magnetron 4 produces continuous microwave energy, through microwave generator 3 microwave energy is sent in seal case 2.In the bottom of seal case 2 an oven dry table top 6 is set, places lithium cell cathode material on the oven dry table top 6.
When the present invention works; From the microwave 5 that microwave generator 3 sends, the stirring of agitator 1 through magnetic field makes the lithium cell cathode material all directions all can absorb microwave energy; Continuous uniform microwave action is in lithium cell cathode material; Thereby it is dried, obtain the low lithium cell cathode material of water content, realize safety clean production.
