Summary of the invention
The utility model is to solve the technical problem that exists in the known technology, and a kind of removal device of large-particle lithium iron phosphate is provided.
The purpose of the utility model provide a kind of have simple in structure, easy to operate, dependable performance, economical and practical, maintenance cost is low, can independence or combined running, continuous productive process continuously, the removal device of the large-particle lithium iron phosphate of characteristics such as production quickness and high efficiency.
The utility model adopts wind-force to brush the LiFePO 4 material that filters out the variable grain degree through the aerial kinetic effect of LiFePO 4 material of variable grain size.This device mainly is made up of blower fan, blast pipe, raw material hopper, tripper, ventilation filter screen, baffle plate, particle bunker for collecting, collection of finished products hopper, fines collection hopper.Blower fan provides suitable wind-force, and it is inner to get into tripper by blast pipe.Material gets into tripper from the raw material hopper, under the effect of wind-force, carries out wind screening, through regulating the size of wind-force, oarse-grained LiFePO4 is dropped in the bulky grain hopper, and the finished product materials with suitable granular size drops in the collection of finished products hopper.And a spot of fine powder LiFePO 4 material drops in the fines collection hopper.Collect the product in the different hoppers respectively, then can obtain removing the LiFePO4 finished-product material of large-particle lithium iron phosphate material and few part fine powder.Blower fan imports air and gets into tripper from the outside, after air is accomplished and blown the effect of branch material, flow out from the ventilation screen portion.The ventilation screen cloth needs regularly cleaning.
The technical scheme that the removal device of the utility model large-particle lithium iron phosphate is taked for the problem that solves the prior art existence is:
A kind of removal device of large-particle lithium iron phosphate; Be characterized in: removal device comprises blower fan, blast pipe, raw material hopper and tripper; Blower fan is communicated with tripper through blast pipe; The raw material hopper is positioned at tripper top, and the tripper bottom is provided with particle bunker for collecting, collection of finished products hopper and fines collection hopper.
The removal device of the utility model large-particle lithium iron phosphate can also adopt following technical measures:
The removal device of described large-particle lithium iron phosphate is characterized in: be provided with baffle plate in the tripper, the particle bunker for collecting of barrier partitions tripper bottom, collection of finished products hopper and fines collection hopper.
The removal device of described large-particle lithium iron phosphate is characterized in: tripper is equipped with the ventilation filter screen.
The removal device of described large-particle lithium iron phosphate is characterized in: the ventilation filter screen on the tripper is equipped with electromagnetic shaker.
Advantage and the good effect that the utlity model has are:
The removal device of large-particle lithium iron phosphate is owing to adopted the utility model brand-new technology scheme; Compared with prior art; The advantage that the removal device of large-particle lithium iron phosphate has: 1, can utilize gravity selection by winnowing effect; Remove the bulky grain in the LiFePO 4 material fully, the particle diameter of the LiFePO 4 material that effective assurance filters out distributes; 2, device structure is simple, and reliability is high; 3, easy to operation, save time; 4, can independently use, also can use, realize the continuous productive process of serialization with other equipment combinations.
The utility model also can be used for the oarse-grained removal of other materials.
Description of drawings
Fig. 1 is the removal device structural representation of the utility model large-particle lithium iron phosphate;
Fig. 2 is a tripper internal structure sketch map.
Among the figure, 1. blower fan, 2. blast pipe, 3. raw material hopper, 4. tripper, 5. ventilation filter screen, 6. baffle plate, 7. particle bunker for collecting, 8. collection of finished products hopper, 9. fines collection hopper.
The specific embodiment
For further understanding technology contents, characteristics and the effect of the utility model, the following examples of giving an example now, and be described with reference to the accompanying drawings as follows:
The removal device of large-particle lithium iron phosphate; Comprise blower fan 1, blast pipe 2, raw material hopper 3 and tripper 4; Blower fan is communicated with tripper 4 through blast pipe; Raw material hopper 3 is positioned at tripper 4 tops, is provided with baffle plate 6 in the tripper 4, and tripper 4 bottoms are provided with particle bunker for collecting 7, collection of finished products hopper 8 and fines collection hopper 9.Baffle plate 6 is separated particle bunker for collecting 7, collection of finished products hopper 8 and the fines collection hopper 9 of tripper bottom.
Tripper 4 is equipped with ventilation filter screen 5.Ventilation filter screen on the tripper is equipped with electromagnetic shaker.
The concrete structure of present embodiment and operating process thereof:
The removal device of large-particle lithium iron phosphate material, mainly by blower fan 1, blast pipe 2, raw material hopper 3; Tripper 4, ventilation filter screen 5, baffle plate 6, particle bunker for collecting 7; Collection of finished products hopper 8, fines collection hopper 9 is formed, and blast pipe 2 links to each other with blower fan 1, and the soft air-flow of different in flow rate can be provided.LiFePO4 receives wind after getting into tripper from raw material hopper 3.Bulky grain will be affected less, can directly fall in the particle bunker for collecting 7.Finished product with suitable granularity will fall in the collection of finished products hopper 8.A spot of fine powder will fall in the fines collection hopper 9, thereby realize oarse-grained removal.
Operating process: open blower fan, in minute hopper, import air-flow through blast pipe.In minute hopper, add LiFePO 4 material to be separated through the raw material hopper.Under the effect of air-flow, divide the granule in the hopper because deadweight is less, can fall into suitable discharging opening along the direction of air-flow.And the LiFePO4 bulky grain can drop in the bulky grain hopper under the gravity effect because deadweight is bigger.After separating completion, stop to feed in raw material, the LiFePO 4 material of separating is collected in closed gas flow output.Ventilation filter screen 5 will regularly clean, in order to avoid stop up.
In the present embodiment, all adopt the manufacturing of SUS304 stainless steel with the material contact portion, the ventilation filter screen adopts the polypropylene non-woven fabric manufacturing.
