Description

Reaction kettle

Technical Field

The utility model relates to a reation kettle field, concretely relates to reation kettle.

Background

In the lithium battery power material industry developing at a high speed, the anode material is developing to the ternary precursor material with high nickel and capacitance, and the original reaction kettle for producing lithium cobaltate, lithium iron phosphate and lithium manganate has a series of problems that the size, the shape and the density of crystals are difficult to control for producing the ternary precursor material, so that the product required by the development of power markets can not be prepared.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the background art, the utility model provides a reaction kettle for producing ternary precursor materials with spherical crystals, high nickel and high temperature performance.

The utility model discloses the technical scheme who adopts: the utility model provides a reaction kettle, its includes the cauldron body and stretches into the rabbling mechanism of the cauldron body, internal charging tube and the overflow pipe of a plurality of groups intercommunication cauldron internal and external that are equipped with of cauldron, the circumference inner wall of the cauldron body is equipped with the spoiler of the vertical setting of a plurality of groups, be equipped with a plurality of finger-like boards that set gradually along length direction on the spoiler.

The stirring mechanism comprises a driving piece, a stirring shaft and a plurality of stirring paddles which are arranged on the stirring shaft at intervals.

The feed pipe in the kettle body is bent, and the outlet of the feed pipe corresponds to the position between the two stirring paddles.

The number of the spoilers is 1-8, and the number of the finger-shaped plates is 2-20.

The inclination angle c of the finger-shaped plates is 30-150 degrees, the distance b between every two finger-shaped plates is 30-1000 mm, and the width of every finger-shaped plate a is 20-500 mm.

The driving piece adopts a motor and a transmission belt mechanism.

The utility model has the advantages that: the utility model provides a reaction kettle, through the spoiler that has the finger-shaped board at the internal wall of reaction kettle, with the help of the spoiler to the vortex effect of internal material of cauldron, strengthen the stirring mixing intensity to the material to improve material reaction uniformity, realize the effective control to production product granularity size and granule crystal maturity, greatly improve material utilization efficiency and product percent of pass; in addition, the combined stirring paddle is adopted, so that the flow field has a large dispersed flow field and a small shearing rate, and meanwhile, finger-shaped disturbance plates in different shapes and different positions are respectively adopted according to the granularity and spherical size requirements of different crystals, so that the pH value and temperature control of the crystal are optimized to the maximum extent.

Drawings

FIG. 1 is a schematic structural diagram of a reaction kettle according to an embodiment of the present invention.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, a reaction kettle comprises a kettle body 1 and an agitating mechanism extending into the kettle body 1, wherein a plurality of groups of feed pipes 2 and overflow pipes 3 which are communicated with the inside and the outside of the kettle body 1 are arranged in the kettle body 1, a plurality of groups of spoilers 4 which are vertically arranged are arranged on the circumferential inner wall of the kettle body 1, and a plurality of finger-shaped plates 5 which are sequentially arranged along the length direction are arranged on the spoilers 4, so that the reaction kettle provided by the utility model has the advantages that the spoilers with the finger-shaped plates are arranged on the inner wall of the kettle body of the reaction kettle, the agitating mixing strength of materials is enhanced by means of the turbulent flow effect of the spoilers on the materials in the kettle body, the reaction uniformity of the materials is improved, the particle size of the produced products and the crystal maturity of the particles are effectively controlled, and; in addition, according to the granularity and spherical size requirements of different crystals, finger-shaped disturbance plates in different shapes and different positions are adopted respectively, so that the pH value and temperature control of the finger-shaped disturbance plates are optimized to the maximum extent.

The stirring mechanism comprises a driving piece 6, a stirring shaft 7 and a plurality of stirring paddles 8 which are arranged on the stirring shaft 7 at intervals, and a combined stirring paddle is adopted, so that the flow field has a large dispersed flow field and a small shearing rate.

The charge tube 2 in the cauldron body 1 is bent and is handled, just the export of charge tube 2 corresponds between two stirring rake 8, makes its added material disperse the mixture in the twinkling of an eye under the effect of stirring rake.

The number of the spoilers 4 is 1-8, and the number of the finger-shaped plates 5 is 2-20.

The inclination angle c of the finger-shaped plates 5 is 30-150 degrees, the distance b between each finger-shaped plate 5 is 30-1000 mm, and the width of each finger-shaped plate 5a is 20-500 mm.

The driving part 6 adopts a motor and a transmission belt mechanism.
