Abstract
The utility model discloses a boron powder grinding device, wherein a rotating shaft is arranged in the center of a grinding cavity, a belt pulley is arranged at the bottom end part of the rotating shaft, and the belt pulley is connected with an output wheel of a speed reducer through a belt; a rotating arm is arranged on the rotating shaft, a long-strip through groove is arranged on the rotating arm, a guide rail is arranged at the edge of the upper part of the long-strip through groove, a sliding block is embedded between the guide rails, the lower part of the sliding block is connected with a pinch roller shaft, and the pinch roller shaft penetrates through the long-strip through groove and is fixed with a pinch roller through a bearing; an outlet is formed in the upper part of the grinding cavity, a filter screen is arranged at the outlet, and a collecting cover is arranged on the grinding cavity outside the outlet; the upper end in grinding the chamber sets up the feed inlet, the lower extreme in grinding the chamber sets up the air intake. The utility model has the advantages that: because the structure that gas blows boron powder to the outlet end is adopted, the boron powder with the particle size meeting the requirement after grinding is discharged through the collecting cover through the filter screen, and the boron powder with the larger particle size falls into the grinding cavity again to be ground again until the boron powder is qualified, so that the particle size requirement is ensured.
Description
Technical Field
The utility model relates to the field of machinary, specifically a grinder of boron powder.
Background
When in use, the boron powder needs to be ground according to the requirement, and the use requirement can be met only when the boron powder reaches a certain granularity requirement.
The existing grinding device usually pours boron powder to be ground into a grinding cavity, and takes out the boron powder after grinding for a certain time, so that the process can not ensure that the boron powder can meet the requirement of granularity, and some overproof boron powder is often mixed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a can the automatic filtration boron powder particle diameter, and guarantee continuity of operation's grinder, concrete technical scheme is as follows:
a boron powder grinding device comprises a grinding cavity, wherein a rotating shaft is arranged in the center of the grinding cavity, a belt pulley is arranged at the end part of the bottom side of the rotating shaft, and the belt pulley is connected with an output wheel of a speed reducer through a belt; a rotating arm is arranged on the rotating shaft, a long through groove is arranged on the rotating arm, a guide rail is arranged at the edge of the upper part of the long through groove, a sliding block is embedded between the guide rails, the lower part of the sliding block is connected with a pinch roller shaft, and the pinch roller shaft penetrates through the long through groove and is fixed with a pinch roller through a bearing; an outlet is arranged at the upper part of the grinding cavity, a filter screen is arranged at the outlet, and a collecting cover is arranged on the grinding cavity outside the outlet; the upper end in grinding the chamber sets up the feed inlet, the lower extreme in grinding the chamber sets up the air intake.
The number of the rotating arms is 2, and the rotating arms are symmetrically arranged at two ends of the rotating shaft in a straight line.
The number of the rotating arms is 4, and the included angle between the rotating arms is 90 degrees.
The feed inlet and the air inlet are arranged on the same straight line passing through the circle center of the rotating shaft.
The filter screen is fixed on the net rack, and the net rack is fixed on the upper end cover of the grinding cavity; the center of the net rack is coupled with the upper end of the rotating shaft.
The utility model has the advantages that: because the structure that the boron powder is blown to the outlet end by gas is adopted, the boron powder with the particle size meeting the requirement after grinding is discharged through the collecting cover by the filter screen, and the boron powder with the larger particle size falls into the grinding cavity again to be ground again until the boron powder is qualified, so the particle size requirement is ensured; in addition, because the centrifugal force is adopted to drive the pinch roller to move towards the wall of the grinding cavity along the radial direction of the rotating arm, the grinding force can be controlled through the rotating speed, and different grinding requirements are met.
