Material.
But LiFePO4 is because specific surface area is big, the moisture in easy absorption air.Due to follow-up Production Process of Lithium Battery
Moisture keep under strict control, it is necessary to which the water content of LiFePO4 product is even lower less than 500ppm, so water content seems in reduction product
It is particularly important.
The method for reducing water content in product is usually to be electrically heated baking water removal, and most of at present is batch (-type)
Heated up, heated in oven, temperature-fall period, but the above-mentioned batch (-type) baking generally used, existence time is long, yields poorly,
The problems such as efficiency is low, labor intensity is big, severe operational environment, it is unfavorable for reducing the production cost of LiFePO 4 material and big rule
Mould industrialization.

This height, it is difficult to the problem of large-scale industrialized production processing.
What the technical solution of the utility model was realized in：
A kind of LiFePO4 drying unit, including microwave heating machine structure are designed, the charging aperture of the microwave heating machine structure connects
The discharging opening of hot body is connect, the charging aperture of the discharging opening connection desiccant body of the microwave heating machine structure, is added in the microwave
The charging aperture and discharging opening of heat engine structure are provided with valve；Microwave generator is installed, the microwave adds in the microwave heating machine structure
The also adjacent guiding transfer member for being provided with the microwave transmission part being horizontally mounted and tilting installation in the inside of heat engine structure；It is described micro-
Ripple transfer member includes main belt, is provided with some charging trays on the main belt, is provided with the both sides of the main belt
Belt speed is identical to turn to two groups of opposite differential conveyer belts to drive rotation of disc, the feeding end and microwave for being oriented to transfer member
The discharge end of transfer member is corresponding, and the discharge end of the guiding transfer member is corresponding with the position of valve.
Preferably, the feeding roller for being oriented to transmission element and including feeding slope frame and being installed on successively in feeding slope frame.Institute
State the hot blast jet pipe that hot body includes being connected with hot air source and be installed on heat with the push pedal at material to valve, the push pedal is pushed
On wind material platform.The desiccant body includes the heater of bottom and the air exhauster at top.The section of the charging tray is round platform
Shape, the edge of charging tray are progressively lower to edge from center.
Beneficial effect caused by the technical program energy is：
By the way of inside and outside while heating, the cycle is short, process is simple, efficiency high, dries more thorough, dried thing
Expect water content≤500ppm, the unchanged requirement that can meet lithium ion battery of pure color；
This technique saves manpower by the way of full-automatic continuous microwave drying, reduces pollution, ensures the body of staff
Body health.Overcome the shortcomings of prior art and a kind of higher efficiency efficiency, the ferric phosphate of conveniently Ultra-low Moisture Content are provided
The stoving process of lithium battery material.
