Abstract

The utility model relates to an agitating mill, which is exclusively used for producing fine particles of graphite in a submicron order. A large quantity of transverse short braces which are arranged on a wall fin of the agitating mill form a pinna shape or a crosswise shape; the surface of a steel ball of a grinding medium is processed into a ragged cambium, and steel balls with different specifications are matched to be used; the agitating mill and the grinding medium increase stirring strength; the fine particles, of the graphite in the submicron order, which are produced by the utility model and the grinding medium are different from the structures of the fine particles, of the graphite in the submicron order, which are produced by other devices and grinding media. The appearance of the utility model is favorable to the exertion of the performance of the graphite, and the utility model is an ideal special-purpose device.

Description

A kind of in order to produce the stirring mill of submicron order graphite particle

The utility model relates to a kind of in order to produce the stirring mill of submicron order graphite particle, belongs to chemical machinery field.

In electronics chemical industry manufacture of materials process, generally adopt equipment such as vibrator, drum ball mill, crushing mill for the grinding of graphite at present.The graphite crystal formation that these several mechanical lappings go out destroys big, influence the performance of graphite serviceability, power consumption is big simultaneously, because will driving cylindrical shell, liner plate, medium and pulverized material, rotates together by the drum-type ball mill, vibrator then drives cylindrical shell, liner plate, medium and material and does dither, and mill Jie steel ball of employing is same specification, and size is identical, any surface finish also influences grinding effect.

It is a kind of in order to produce the stirring mill of submicron order graphite particle that the purpose of this utility model is to provide, this stirring mill must be situated between with special mill and be used, be exclusively used in and produce the submicron order graphite particle, it is to adopt difform mixing arm that special mill is situated between to run foul of each other with material and shear, thereby reaches the purpose of comminuting matter.

The utility model is realized by following process, stirs mill and comprises that motor, transmission mechanism, ball milling bucket, the circulatory system, cooling system, shaft, mixing arm and mill are situated between; Motor links to each other with shaft by transmission mechanism, and mixing arm is fixed on the shaft, and the circulatory system comprises pump and pump motor, is installed in the two ends up and down of ball milling bucket by pipeline; Two warter connections are arranged on the cooling system, and top connection is a water inlet, and lower contact is a delivery port; There is discharging opening ball milling bucket lower end, rear side has charging aperture, below two mixing arms be crosswise, each mixing arm is 30 ° of angles and intermeshes and be installed on the shaft, four arm wings are arranged on each mixing arm, have some horizontal short supports on each arm wing, the arrangement of short support inwardly is pinniform, also can be crosswise, intersect mutually, the three-dimensional arrangement, uppermost mixing arm is a disc, there is short support in the dish outside.

Mill is situated between and is the steel ball of different size, and its surface becomes a scraggly formation layer through specially treated, and its steel ball specification is respectively φ 11, φ 8, φ 5.

Adopt this equipment can produce following good effect; must be equipped with above-mentioned mill simultaneously with this equipment is situated between; with this submicron order graphite particulate of producing performance and other method intensity, appearance, the size distribution of producing different; its crystal formation keeps the 2H crystal formation substantially; and need not shut down and material can be discharged in producing, mixing arm and steel ball stir great efforts, and grinding effect is good; more adapting to peeling off of graphite layers, is a kind of more satisfactory equipment of producing graphite particle.

Be described in further details below in conjunction with drawings and the specific embodiments.

Fig. 1 is the structural representation of stirring mill of the present utility model;

Fig. 2 is the structural representation of mixing arm of the present utility model;

Fig. 3 is the another kind of embodiment structural representation of mixing arm of the present utility model;

Fig. 4 is the structural representation that mill of the present utility model is situated between;

As seen from Figure 1, the shaft 5 that stirs mill links to each other with transmission mechanism 2, drives shaft 5 by motor 1 and rotates, and between ball milling bucket 3 and the shell 7 interlayer is arranged, and is used for cooling device, and cooling water enters from the last end entrance 4 of interlayer, exports 11 discharges from the lower end; The circulatory system comprises pump 9 and pump motor 10, and pump 9 is linked to each other by the two ends up and down that pipeline is installed in ball milling bucket 3; Material is extracted out from the lower end of ball milling bucket 3 by pump 9 after grinding, and squeezes into from the upper end the ball milling bucket 3 and further grinds, and has a lid to be charging aperture (cannot see among the figure) at the rear side of ball milling bucket, at downside one discharging opening 8 is arranged, and mixing arm is installed on the shaft 5; Find out that from Fig. 2 and Fig. 3 mixing arm 6 is a crosswise, four arm wings, many horizontal short supports are all arranged on each arm wing, short support is arranged and inwardly is pinniform, and is interlaced, the three-dimensional arrangement, another kind of embodiment is: short support is cross, interlaced, the three-dimensional arrangement, mixing arm 12 is for being disc, there is short support in the outside, and it has the sedimental effect of ball milling bucket 3 inwalls of removing simultaneously, and the arm wing of this stirring mill is exclusively used in produces the submicron order graphite particle; As seen from Figure 4, grind the treated coarse injustice that becomes of matching used mill Jie steel ball surface with this stirring, form a convex-concave layer, this structure has increased the stirring dynamics greatly, join φ 11, φ 8,5 three kinds of specifications of φ during use, be situated between and stir graphite particulate minor structure that mill produces in the form of sheets by this mill, the graphite particulate minor structure needle-like of producing with miscellaneous equipment and mill Jie is different, this is miscellaneous equipment and the inaccessible result of mill Jie, and this stirring mill must be used just and can achieve the above object with this mill Jie.

Earlier mill Jie steel ball of different size is packed into during use in the ball milling bucket 3, more main motor is opened, the material that the prepares bonnet from ball milling bucket 3 is added, open pump motor 9, timing then is in process of lapping, material from the lower end suction, enters the upper end of ball milling bucket 3, circular grinding through pump; After finishing, close the discharging opening of pump 8, promptly the last end entrance of ball milling bucket 3 is opened discharge gate 11, material is discharged, and need not shut down.
