Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The vertical stirring ball mill for tungsten carbide shown in figure 1 is used for stirring and grinding tungsten carbide and comprises a driving motor 1 and a shell 2, wherein the driving motor is arranged at the top of the shell, a multi-stage stirring cabin is arranged in the shell, and a supporting turntable 3 is arranged in the shell at the lower side of the multi-stage stirring cabin; a stirring shaft 4 is arranged in the multistage stirring cabin, the top end of the stirring shaft is fixedly connected with an output shaft of the driving motor, and the bottom end of the stirring shaft is fixedly connected to the supporting turntable. The driving motor provides power output for the stirring shaft, and the stirring shaft is driven to rotate to stir and grind the tungsten carbide in the multistage stirring cabin. The support carousel of bottom is used for spacing the bottom of (mixing) shaft, prevents at rotatory in-process, and the bottom of (mixing) shaft takes place to deflect.
The trisection position on the stirring shaft is respectively and fixedly connected with a first-stage filter disc 5 and a second-stage filter disc 6, and when the stirring shaft rotates, the first-stage filter disc and the second-stage filter disc also rotate along with the rotation of the stirring shaft. The primary filter disc is positioned above the secondary filter disc, and a plurality of material through holes which are communicated up and down are formed in the disc surfaces of the primary filter disc and the secondary filter disc;
a plurality of primary grinding balls 10 are contained in the primary stirring cabin 7 above the primary filter disc, a plurality of secondary grinding balls 11 are contained in the secondary stirring cabin 8 between the secondary filter disc and the primary filter disc, and a plurality of tertiary grinding balls 12 are contained in the tertiary stirring cabin 9 below the secondary filter disc; the diameter of one-level grinding ball is greater than the diameter of second grade grinding ball, and the diameter of second grade grinding ball is greater than the diameter of tertiary grinding ball, and the diameter of second grade grinding ball is greater than the aperture of material through-hole.
The feed inlet 13 has been seted up at the top in multistage stirring cabin, and tungsten carbide enters into the one-level stirring cabin at first from the feed inlet, because the diameter of one-level ball is big, and the one-level ball in the one-level stirring cabin can carry out the corase grind to tungsten carbide, and the tungsten carbide through the corase grind enters into the second grade stirring cabin through the material through-hole on the one-level filter disc. Because the diameter of the secondary grinding ball is smaller than that of the primary grinding ball, the tungsten carbide can be further finely ground under the grinding of the secondary grinding ball. The tungsten carbide after the fine grinding enters the third-stage stirring cabin from the material through hole on the second-stage filter disc, and the diameter of the third-stage grinding ball is further reduced, so that the tungsten carbide is finely ground under the grinding of the third-stage grinding ball, the ground powder is finer, and the granularity is more uniform. Finally, the milled tungsten carbide leaves the multistage mixing chamber from the bottom discharge port 14. The discharge port can be provided with a pump for pumping out the tungsten carbide.
Wherein, the first-order filter disc and second grade filter disc all have the interval with the inner wall of multistage stirring cabin, and the interval is less than the diameter of second grade ball. The interval is used for keeping apart filter disc and stirring cabin inner wall, prevents that pivoted filter disc and stirring cabin inner wall from taking place the friction, causing wearing and tearing. And because the diameter of the material through hole is also smaller than that of the second-stage grinding ball, the second-stage grinding ball can be prevented from falling into the third-stage stirring cabin from the material through hole or the interval of the filter disc.
In a similar way, the diameter of the first-stage grinding ball is larger than that of the second-stage grinding ball, so that the first-stage grinding ball can not fall into the second-stage stirring cabin from the material through holes on the first-stage filter disc or the first-stage filter disc at intervals. The grinding balls are ensured to be positioned in the corresponding stirring cabins.
The discharge port is provided with a filter screen 15, and the diameter of the filter screen is smaller than that of the third-stage grinding ball. The filter screen is used for preventing the tertiary ball mill from leaving the stirring cabin along with the tungsten carbide.
The support turntable is mounted on a turntable base 16, the support turntable being rotatable relative to the turntable base.
The side wall of the shell is respectively provided with a cabin door corresponding to the first-stage stirring cabin, the second-stage stirring cabin and the third-stage stirring cabin. The grinding balls in the corresponding stirring cabin can be increased, decreased or replaced through the cabin door.
The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
