Detailed Description
The technical scheme claimed in the application is based on the following technical scheme of patent protection filed on the same date as the application:
as shown in fig. 1 and 3, the pneumatic grinding ball device for the microwave ferrite detection ball comprises a tank body 1 with an upward opening, a tank cover 2 for covering the tank opening of the tank body 1, an exhaust hole 201 arranged on the tank cover 2, and a pneumatic mechanism, wherein the pneumatic mechanism comprises an air pipe 3 communicated with a high-pressure air source and a nozzle 301 arranged at the terminal end of the air pipe 3, and the nozzle 301 is arranged in the tank cavity 101 of the tank body 1 according to the tangential direction of the inner wall of the tank cavity 101 of the tank body 1. In use, the air flow emitted by the nozzle 301 forms a cyclone within the tank 101 that can push the detection ball. The apparatus further comprises a pneumatic rotation mechanism by which the nozzle 301 is rotated relative to the inner wall of the tank 101 by the pneumatic rotation mechanism by means of the pneumatic power of the air jet ejected by the nozzle 301. The pneumatic rotating mechanism comprises a shaft 4 vertically arranged and a bearing 5 sleeved on the shaft 4, the nozzle 301 rotates relative to the inner wall of the tank cavity 101, the tank body 1 is arranged on the bearing 5, high-pressure air flow sprayed out of the nozzle 301 forms friction force along the tangential direction on the inner wall of the tank cavity 101, and the tank body 1 can rotate around the shaft 4 under the condition that the shaft 4 is not moved. The shaft 4 is vertically hung, the center of the tank cover 2 is provided with a bearing mounting hole, and the tank body 1 is mounted on the bearing 5 and sleeved on the bearing 5 through the mounting hole of the tank cover 2 covered on the tank body 1. The pneumatic rotation mechanism also comprises a clamping spring 6 which is arranged on the shaft 4 below the bearing 5 and is used for upwards supporting the inner ring of the bearing 5. That is, the entire can 1 is mounted in a suspended manner on the shaft 4.
The effect of rotating the tank 1 around the shaft 4 is not to produce an effect on the grinding balls, but to prevent the air flow from being aligned with a certain position of the inner wall of the tank cavity 101 for a long time, and to prevent the inner wall of the position from being worn out due to the fact that deeper and deeper grinding pits are formed in the position. After the tank body 1 rotates, the peripheral wall of the tank cavity 101 is flushed in turn, and the tank body is not fixedly concentrated in a certain place, so that the service life of the tank body 1 is prolonged by a plurality of times. Based on the above meaning of the rotation of the can 1, the can 1 is not required to rotate rapidly as long as it can rotate, but rather, the slower the rotation speed, the more beneficial the improvement of the relative speed of the detection ball in friction rolling on the peripheral wall of the can cavity 101, so that the speed of the can 1 needs to be controlled in a decelerating manner.
The present utility model will be described in detail with reference to the following examples and the accompanying drawings.
Example 1
As shown in fig. 1 and 2, a speed reducing mechanism of a rotary tank body 1 of a pneumatic ball grinding device for detecting microwave ferrite is characterized in that an annular lower wear-resisting plate 8 fixedly arranged with the tank cover 2 is arranged on the top surface of the tank cover 2 outside a bearing mounting hole, an upper wear-resisting plate 7 sleeved on a shaft 4 is arranged above the lower wear-resisting plate 8, and the upper wear-resisting plate 7 is circumferentially limited on the shaft 4 and can axially slide to be attached to or detached from the lower wear-resisting plate 8. When the upper wear plate 7 is attached to the lower wear plate 8, the rotation of the tank 1 is subjected to frictional resistance between the upper wear plate 7 and the lower wear plate 8, thereby achieving the effect of slowing down the rotation speed.
In order to adjust the frictional resistance between the upper wear plate 7 and the lower wear plate 8, a pressing mechanism is provided above the upper wear plate 7.

When the pressure regulating sleeve 9 is rotated to make it downward, the upper wear plate 7 can be pressed against the lower wear plate 8 by the elastic member 10 to control the rotation speed of the tank 1.
The elastic member 10 may be a spring or a rubber body.
The upper end of the pressure adjusting sleeve 9 is provided with a section of temporary positioning sleeve 901 without internal threads, the temporary positioning sleeve 901 is provided with radial threaded holes, and bolts 11 capable of supporting the shaft 4 are arranged in the threaded holes. When the pressure adjusting sleeve 9 is rotated to a certain position, the bolt is used for abutting the shaft 4, so that the pressure adjusting sleeve 9 is prevented from rotating again.

Example two

In this way, the pressure of the upper wear plate 7 to the lower wear plate 8 can be regulated by rotating the pressure regulating sleeve 9, and the upper wear plate 7 can be lifted upwards to be separated from the lower wear plate 8 when the rotating speed of the tank body 1 needs to be increased.
Example III
