Abstract
The utility model discloses a drying device for performing solid-liquid separation after lithium ion phosphate grinding. The drying device comprises a double-cone dryer and a liquid storage tank, a feed pipe is mounted at the lower end of the double-cone dryer, the upper end of the liquid storage tank is formed with a liquid inlet and an exhaust hole while the lower end is formed with a liquid outlet, the liquid inlet is connected with a quick coupling through a pipeline, the quick coupling is abutted with the feed pipe, the pipeline is further provided with a Y-shaped filter and a flow rate meter, the exhaust hole is connected with a vacuum pump through an air pipe, and the liquid outlet is provided with a valve. The drying device for performing the solid-liquid separation after the lithium ion phosphate grinding is capable of shortening the drying time, improving the organic solvent recovery and lowering the organic solvent utilization, and accordingly the production cost is lowered.
Description
Technical field
The utility model relates to a kind of drying device that grinds rear Separation of Solid and Liquid for LiFePO4.
Background technology
At present LiFePO4 all adopts presoma wet method to carry out operation, its general ball-milling medium using of process of lapping be a large amount of organic solvent as absolute ethyl alcohol, absolute ethyl alcohol does not participate in chemical reaction, needs to adopt means of different, to realize Separation of Solid and Liquid.The means of at present industrial general employing are dry, as dry in vacuum drying, spraying etc.
The shortcomings such as boulton process, because it need all evaporate the organic solvent that participates in ball milling, thereby exists energy consumption large, and drying time is long, and the organic solvent rate of recovery is not high.Spray drying process, because the decentralized medium that participates in presoma ball milling is organic solvent, thus very high to spray drying device requirement, need be with explosion-protection equipment, cost is higher; Same its need all evaporate the organic solvent that participates in ball milling, and energy consumption is large.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of drying device that grinds rear Separation of Solid and Liquid for LiFePO4.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of grind for LiFePO4 after the drying device of Separation of Solid and Liquid, comprise double-cone dryer, the lower end of described double-cone dryer is provided with feed pipe, further comprise a fluid reservoir, the upper end of described fluid reservoir is provided with inlet and aspirating hole, and lower end is provided with liquid outlet, and on the can body of fluid reservoir, is also provided with a form of being convenient to observation; Described inlet connects a snap joint by pipeline, and described snap joint is docked with described feed pipe, and y-type filter and flowmeter are also installed on described pipeline; Described aspirating hole is connecting a vavuum pump by tracheae; Described liquid outlet is provided with a valve.
Compared with prior art, the utlity model has following beneficial effect: (1) the utility model adopts first suction filtration vacuum drying ferric lithium phosphate precursor again, can shorten drying time and improve the rate of recovery of organic solvent, reduce organic solvent to sintering furnace, the particularly impact of heating wire, and then reduce production costs.
(2) the utlity model has that production process is continuous, product property is even, stay-in-grade feature, and simple for process, and suitability for industrialized is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, a kind of drying device that grinds rear Separation of Solid and Liquid for LiFePO4 the utility model proposes, comprise double-cone dryer 1, the lower end of double-cone dryer 1 is provided with feed pipe 11, further comprise a fluid reservoir 5, the upper end of fluid reservoir 5 is provided with inlet and aspirating hole, and lower end is provided with liquid outlet, and on the can body of fluid reservoir 5, is also provided with a form 7 of being convenient to observation; Inlet connects a snap joint 2 by pipeline, and snap joint 2 is docked with feed pipe 11, and y-type filter 3 and flowmeter 4 are also installed on pipeline; Aspirating hole is connecting a vavuum pump 6 by tracheae; Liquid outlet is provided with a valve 51.
The utility model is in the time of concrete use, until LiFePO4 raw material after wet ball grinding, slurry is squeezed in double-cone dryer 1 from feed pipe 11, the feed pipe 11 of transferring again, snap joint 2 is connected with the feed pipe 11 on double-cone dryer 1, open vavuum pump 5, by y-type filter 3, realize most of Separation of Solid and Liquid of slurry; After treating there is no solvent streams on flowmeter 4, Separation of Solid and Liquid completes, and takes off snap joint 2, closes material inlet valve and venting valve on drying machine 1, separates the dry of rear solid.Solvent after separation flows in fluid reservoir 5, by the upper visor window observation solvent recovery reserves of fluid reservoir 5, in the time that liquid level did not have upper visor window top soon, by the valve of fluid reservoir 5 bottoms, can emit solvent.Solvent recovering rate reaches 85%, and this device institute recovered solvent can use by direct circulation.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
