Technical field
The utility model is related to a kind of lithium battery pole slice drying units, belong to lithium battery production technical field.
Background technology
It needs to dry after the completion of electrodes of lithium-ion batteries coating, however drying mostly uses hot-air drying device at present, still
This drying equipment high energy consumption, efficiency is low, and case interior air-flow is irregular, can not be effectively protected to electrode slice and coating, most
Cause pole piece drying degree irregular eventually, the problems such as bubble, pin hole, cracking often occur, the rejection rate of battery pole piece is caused to increase,
Greatly reduce lithium battery automated production level, it is therefore desirable to the pole piece drying unit that a kind of energy consumption is low, drying efficiency is high.
Utility model content
To solve problems of the prior art, the utility model provide a kind of simple in structure, dedusting without dead angle, remove
The good lithium battery pole slice drying unit of dirt effect.Specific technical solution is as follows：
A kind of lithium battery pole slice drying unit, including drying box, the drying box middle part are equipped with horizontal through the drying
Battery pole piece inside case, the both sides of the battery pole piece are equipped with the heating mechanism of mirror image distribution, and the heating mechanism includes gas
Cylinder, vertical supporting plate and two carbon-crystal electric hot plates, two carbon-crystal electric hot plate are hingedly arranged in the vertical supporting plate, two carbon crystals
Electric hot plate is at flare openings, and the battery pole piece part is stretched into the flare openings that two carbon-crystal electric hot plate is formed, institute
It states vertical supporting plate upper/lower terminal and is equipped with fixed pulley, the dry box outer wall is equipped with the tensioning being used cooperatively with fixed pulley
Wheel, the tensioning wheel are sequentially connected fixed pulley and carbon-crystal electric hot plate by cotton rope, and the carbon-crystal electric hot plate connects power supply.
Further, the drying box upper end is additionally provided with air outlet, and the air outlet is just corresponding to the battery pole piece.
Further, two carbon-crystal electric hot plates in the vertical supporting plate are symmetrical about the battery pole piece.
Further, the air outlet passes through pipeline connection dehumidifier.
The utility model has the beneficial effects that：The utility model using carbon-crystal electric hot plate as heating element, not only electric energy
The efficient of thermal energy is converted to, energy consumption is small, and bubble occurs in pole piece, cracking is damaged caused by avoiding traditional hot-air seasoning uneven
Wound, while the heat radiation space of carbon-crystal electric hot plate and angle of radiation are adjustable in the utility model, increase it and dry use scope.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of lithium battery pole slice drying unit of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of lithium battery pole slice drying unit, including drying box 1,1 middle part of the drying box are equipped with level
Battery pole piece 2 inside the drying box 1, the both sides of the battery pole piece 2 are equipped with the heating mechanism of mirror image distribution, described
Heating mechanism includes cylinder, and cylinder includes cylinder body end 6, tailpiece of the piston rod 5, vertical supporting plate 4 and two carbon-crystal electric hot plates 3, and described two
Carbon-crystal electric hot plate 3 is hingedly arranged in the vertical supporting plate 4, and two carbon-crystal electric hot plates 3 are at flare openings, the battery pole piece
2 parts are stretched into the flare openings that two carbon-crystal electric hot plate 3 is formed, and 4 upper/lower terminal of the vertical supporting plate is equipped with fixed
Pulley 7,1 outer wall of the drying box are equipped with the tensioning wheel 9 that is used cooperatively with fixed pulley, the tensioning wheel 9 by cotton rope successively
Fixed pulley 7 and carbon-crystal electric hot plate 3 are connected, the carbon-crystal electric hot plate 3 connects power supply.
In above-mentioned technical proposal, the heating principle of carbon-crystal electric hot plate 3 is：Under electric field action, the carbon molecules in heater
Group generates molecular motion, generates violent friction and shock between carbon atom, and the heat of generation is with far infrared radiation and convection current
Form is externally transmitted, and the conversion ratio of electric energy and thermal energy is up to 98% or more.
When the utility model specific works, the battery pole piece after the completion of double spread is passed through from 1 center of drying box, carbon crystal electric
3 electrified regulation of hot plate generates the upper and lower surface that far infrared radiation is radiated at battery pole piece 2, in battery pole piece surface size
Moisture is dried, and moisture evaporation is made to complete the drying of battery pole piece；Before drying, it can be passed through according to the width of battery pole piece
Cylinder adjusts the distance between two vertical supporting plates 4, meets the drying of different in width battery pole piece, while adjusting tensioning wheel 9
It adjusts the extended length of cotton rope and then adjusts the angle between carbon-crystal electric hot plate 3 and battery pole piece 2 so that carbon-crystal electric hot plate 3 produces
The angle that raw Thermal Infra-Red projects battery pole piece is best, improves drying efficiency and the scope of application.
1 upper end of the drying box is additionally provided with air outlet 11, and the air outlet 11 is just corresponding to the battery pole piece 2, battery pole
The steam that 2 dry tack free of piece generates can be discharged by air outlet 11, and avoid steam from overstocking influences rate of drying in drying box.
Two carbon-crystal electric hot plates 3 in the vertical supporting plate 4 are symmetrical about the battery pole piece 2, can ensure electricity
The upper and lower surface heat radiation uniformity of pond pole piece is not in that pole piece caused by drying is uneven damages.
The air outlet 11 by pipeline connection dehumidifier 12, dehumidifier 12 can efficient absorption steam, improve steam
The rate of drying box is discharged, further improves drying efficiency.
The utility model electric energy high conversion rate, energy consumption is small, and pole piece caused by avoiding traditional hot-air seasoning uneven damages, and
The heat radiation space of carbon-crystal electric hot plate and angle of radiation are adjustable, increase it and dry use scope.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
