So that lithium battery is not applied within some time after being proposed first；With the development of science and technology, present lithium battery
Have become main flow.
Lithium battery can substantially be divided into two major classes：Lithium metal battery and lithium ion battery.Lithium ion battery does not contain metal
The lithium of state, and charging operations can be carried out.5th generation product lithium metal battery of rechargeable battery was born in 1776, its safety
Property, specific capacity, self-discharge rate and cost performance are superior to lithium ion battery.Because the high-tech of its own requires to limit, existing
The company for having a few countries is producing this lithium metal battery.
The method for preparing lithium iron phosphate positive material in the prior art is to be sent into the slurry uniformly mixed to be spray-dried
In tower, slurry is sprayed by atomizer sprayer, mixed in drying tower entrance with hot-air, but because phosphoric acid is big, easily
Cause the blocking of atomizer and cause equipment not run steadily in the long term, therefore its structure is further improved.
Utility model content
To solve the problems, such as that present technology is present, the utility model provides a kind of simple in construction, stable, drying effect
Good lithium iron phosphate positive material production drying device.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of lithium iron phosphate positive material production drying device, includes drying tower, and the upper end of described drying tower is set
Atomizer is equipped with, the atomizer is connected with slurry pipe, and shurry pump is provided with described slurry pipe, and described slurry pipe passes through
It is provided with the heat exchanger of heating tube；The bottom of described drying tower is provided with whirlwind generator, in described whirlwind generator
Cross one another double helix air channel is provided with, the top of described drying tower is provided with heat blower, and described hot blast occurs
Device includes air-introduced machine and inlet manifold, and an at least discharge pipe is connected on described inlet manifold, is set on described discharge pipe
It is equipped with the heating element for being capable of regulation heating temperature.
The technical measures of optimization also include：
Described shurry pump is in continuous S-shaped structure setting in the heat exchanger.
Described discharge pipe totally two, the heating element independent control on two discharge pipes.
Described double helix air channel and the angle of horizontal plane are 20 ° to 30 °.
After the technical solution of the utility model, heat exchanger is set before drying tower, slurry is being delivered to atomization
Heat exchange occurs with heat exchanger before device, the part moisture content allowed in slurry is evaporated, and so as to reduce the viscosity of slurry, and then is reduced
The blocked probability of atomizer sprayer, to ensure the stable operation of equipment；Cross one another double spiral shells are used in whirlwind generator
Whirlwind road, wind-force can be strengthened, so as to reduce reduction speed of the raw material in drying tower, improve drying effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference therein is：Drying tower 1, atomizer 2, slurry pipe 3, heat exchanger 4, whirlwind generator 5, double helix
Air channel 51, air-introduced machine 61, inlet manifold 62, discharge pipe 63, heating element 64.
Embodiment
As shown in figure 1,
A kind of lithium iron phosphate positive material production drying device, include drying tower 1, the upper end of described drying tower 1
Atomizer 2 is provided with, the atomizer 2 is connected with slurry pipe 3, and shurry pump 31, described material are provided with described slurry pipe 3
Slurry pipe 3 passes through the heat exchanger 4 for being provided with heating tube；The bottom of described drying tower 1 is provided with whirlwind generator 5, described
Cross one another double helix air channel 51 is provided with whirlwind generator 5, the top of described drying tower 1 is provided with hot blast
Device, described heat blower include air-introduced machine 61 and inlet manifold 62, discharge pipe are connected with described inlet manifold 62
63, the heating element 64 for being capable of regulation heating temperature is provided with described discharge pipe 63.
Described shurry pump 31 is in continuous S-shaped structure setting in the heat exchanger 4.Material can be increased by being arranged such
Length of the stock pump 31 in heat exchanger 4, so as to increase heat exchanger time, improve slurry moisture evaporation in heat exchanger 4 and imitate
Fruit.
Described discharge pipe 63 totally two, the independent control of heating element 64 on two discharge pipes 63.
Two discharge pipes 63 are set, and the heating element 64 being respectively arranged on discharge pipe 63 can be with independent control, so
It can as needed select using a discharge pipe 63 or two discharge pipes 63 while use, to meet the need of different situations
Will.In addition, two discharge pipes 63 can use in turn, avoid single discharge pipe 63 always using and caused by service life subtract
It is few, the stability of equipment operation can be so improved, reduces maintenance cost.
