Description

Drying device for lithium carbonate production

Technical Field

The utility model relates to the field of lithium carbonate production, in particular to a drying device for lithium carbonate production.

Background

Lithium carbonate is an inorganic compound, is colorless monoclinic crystals or white powder, and is extremely widely used, for example, in the production of various lithium compounds, metallic lithium and isotopes thereof. And also has applications in the semiconductor, ceramic, television, pharmaceutical and atomic energy industries. Analytical chemistry was used as the analytical reagent. And also has application in lithium ion batteries.

The general industrial salt lake brine finally prepares lithium carbonate through a plurality of processing steps, the last step is drying of lithium carbonate, and in the process of using drying equipment for lithium carbonate production, the drying is carried out by directly blowing hot air, so that partial lithium carbonate is blocked, the use is affected, and the traditional stirring mode can not well turn over lithium carbonate materials, so that the drying is incomplete.

The utility model provides a drying device for lithium carbonate production based on at least one of the technical problems.

A drying device for lithium carbonate production includes: the drying box is fixed on the base through a bracket, a feed inlet is formed in the upper portion of the drying box, hot air pipes are respectively arranged at four corners of the drying box, a motor is arranged on one side of the drying box, an output shaft of the motor drives a rotating shaft at the middle of the drying box to rotate, stirring blades are arranged on the rotating shaft, and the stirring blades are staggered on the rotating shaft; the lower part of the drying box is provided with a funnel-shaped blanking part, a vibrating screen is arranged in the blanking part, and a small-sized vibrating motor is arranged on the vibrating screen.

Further, the hot air pipe at the upper part of the drying box blows downwards obliquely, and the hot air pipe at the lower part of the drying box blows upwards obliquely.

Further, the bottom of the feed inlet is an inclined pipe inclined towards the middle of the drying box.

Further, an arc-shaped filter screen is arranged at the lower part of the drying box, and the blanking part is arranged below the filter screen.

Further, the lower end of the blanking part is sleeved with a surrounding sail, and a conveying belt is arranged below the surrounding sail.

The beneficial effects are that: the device adopts a multi-angle hot air ventilation mode, is matched with spiral stirring, can smash agglomerated lithium carbonate to sufficiently dry, and is matched with a vibrating screen to screen lithium carbonate meeting the requirements.

Detailed Description

In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

A drying apparatus for lithium carbonate production as shown in fig. 1, comprising: the drying box 1, the drying box 1 is fixed on the base 3 through the bracket 2, the upper part of the drying box 1 is provided with a feed inlet 4, four corners of the drying box 1 are respectively provided with a hot air pipe 9, one side of the drying box 1 is provided with a motor 6, the output shaft of the motor 6 drives a rotating shaft 7 in the middle of the drying box 1 to rotate, the rotating shaft 7 is provided with stirring blades 8, and the stirring blades 8 are arranged on the rotating shaft 7 in a staggered manner; the lower part of the drying box 1 is provided with a funnel-shaped blanking part 10, a vibrating screen 12 is arranged in the blanking part 10, and a small-sized vibrating motor 13 is arranged on the vibrating screen 12.

The specific working process is as follows: the wet material of lithium carbonate enters into stoving case 1 inside from feed inlet 4, and this moment motor 6 high-speed rotation breaks the wet material of lithium carbonate, and the hot-blast stoving case 1 of blowing into from four hot-blast pipes 9 is dried with lithium carbonate, and at this in-process, the hot-blast turbulence that forms of hot-blast cooperation hot-blast pipe 9 blowout in four corners in stoving case 1 can guarantee that the wet material of lithium carbonate fully contacts with hot-blast, and falls into on the shale shaker 12 again after keeping certain stoving time.

The hot air pipe 9 positioned at the upper part of the drying box 1 blows downwards in an inclined way, and the hot air pipe 9 positioned at the lower part of the drying box 1 blows upwards in an inclined way.

Specifically, the hot-blast pipe 9 is in the cross blow of stoving case 1, and the back is down to the wet material of lithium carbonate, and crisscross hot-blast can keep the lithium carbonate material can not directly fall, and cooperation pivoted stirring leaf 8 can fully be with it after drying again whereabouts.

The bottom of the feed inlet 4 is provided with an inclined pipe 5 which inclines towards the middle part of the drying box 1.

Specifically, the inclined tube 5 is used for preventing the hot air pipe 9 from directly blowing to the inclined tube 5 to influence the blanking.

An arc-shaped filter screen 11 is arranged at the lower part of the drying box 1, and a blanking part 10 is arranged below the filter screen 11.

Specifically, the filter screen 11 can keep the large-particle lithium carbonate which does not meet the requirements on the filter screen 11, and the hot air in the drying box 1 can be blown to the filter screen 11, because the rotating shaft 7 rotates, the drying box 1 can vibrate, the filter screen 11 can perform a certain screening effect, and the hot air in the drying box 1 is matched with the small-particle lithium carbonate on the filter screen 11 to directly dry, so that the drying effect is ensured, and the filter screen 11 can be made of heat-conducting metal.

A sail 14 is sleeved at the lower end of the blanking part 10, and a conveyor belt 15 is arranged below the sail 14.

In particular, the arrangement of the enclosing sail 14 can prevent the dry lithium carbonate from being blown up, and ensure that the dry lithium carbonate can stably fall on the conveyor belt 15.

In the present apparatus, the ventilation air speed of the hot air duct 9 is a medium speed air in order to prevent the hot air from being directly blown out from the lower portion of the drying box 1 at a high speed.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
