Lithium Iron Phosphate Double Cone Rotary Vacuum Dryer
Project description:
In recent years, China lithium battery production has increased dramatically, by the end of 2009, production of lithium-ion battery cable up to 1.875 billion dollars. Lithium battery cathode materials have also been from a single lithium cobalt oxide materials, the development of lithium cobalt oxide, lithium manganese oxide, lithium nickel and cobalt, nickel, cobalt and lithium manganese oxide, lithium iron phosphate and other materials go hand in hand stage. Driven by the growth in the lithium battery market, lithium battery material upward trend in the overall market, lithium cathode materials research progress made with regard to show that its market prospects.
Lithium iron phosphate lithium initiator is a new revolution in the industry and new materials, is at the forefront of the development of lithium battery industry. Lithium iron phosphate because of its advantages are widely used in hybrid vehicles, power tools, electric white road, electric bikes, energy storage devices. Hybrid electric vehicle (HEV) is the next few years the main direction of development of new energy vehicles. With the increasing production of hybrid vehicles, hybrid vehicles to enhance share, lithium iron phosphate market will grow rapidly.
Item Description:
Lithium-ion battery performance depends mainly on the anode and cathode materials, lithium iron phosphate as a new lithium ion battery cathode material, its safety performance and cycle life than other cathode material has obvious advantages, the battery is also the most important technical indicators . Lithium iron phosphate with non-toxic, harmless, safe and good, long life and other advantages, has become a new generation of lithium-ion batteries ideal cathode material.
Working principle:
Double cone rotary vacuum dryer double cone rotating tank, the intermediate device is cylindrical, conical ends, at the top of the cone is designed to open a feed (doubles manhole), and the other end is a discharge valve. Tank vivo divided into three layers, the intermediate jacket heating medium may be steam, hot water or thermal oil cycle, the insulation layer in the base fine glass wool, minimal power consumption; an inner layer serving materials. Work tank in a vacuum state, to the jacket into a thermal oil, hot water or steam for heating heat medium, the heat transfer to the wet material through the tank wall.
Since the tank body in a vacuum, all kinds of materials in the solvent (including water) can rapidly vaporized under vacuum conditions at a lower temperature, and the rotation of the tank so that the material continuously from top to bottom, inside and outside turning, constantly updated material surface in contact with the wall, to make full use of the heat conduction of the wall, to speed up the drying rate of materials, improve drying efficiency, and to achieve uniform drying purposes.
Evaporation of the solvent (water vapor) after wet material absorbs heat through vacuum exhaust pipe is withdrawn. Halfway through the cryogenic condensation system (using water or frozen brine) is cooled in order to achieve the purpose of recycling, saving production costs and improve the working conditions of the vacuum pump, further reducing environmental pollution.
