Lithium iron phosphate double cone rotary vacuum dryer
Detailed description
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.
