The friction in the stirring device comes from two aspects: firstly, friction is generated due to different motion directions; the second is the friction generated by the difference of the inner and outer movement speeds. The steel shots and the large-particle dust particles in the recovery box fall into the stirring device, and are rubbed with each other under the action of the stirring shaft and the rotating blades, so that the surfaces of the steel shots become smooth, and the dust particles are broken into smaller particles. The air current that jet-propelled fan produced enters into agitating unit by the jet-propelled mouth, blows the top with the less dust granule of bottom, falls the upper surface of shot and dust granule under the effect of filter screen, improves agitating unit to the crushing effect of great dust granule. The first rotating motor is a one-way motor, and rotates at intervals, so that mutual friction in the stirring device can be increased. Since the dust particles entering the stirring device are not removed by the dust removal fan, the volume and the mass of the dust particles are large, and therefore the dust particles need to be conveniently separated after being crushed.

The situation of the ground to be processed is recorded through the image detection equipment, the data are intelligently analyzed through the processor, if the proportion of spherical pits formed by the impact of the steel shots is reduced, the dust particles are not completely crushed by the stirring device, the larger dust particles and the steel shots are thrown out by the shot blasting wheel, and the stirring speed of the stirring device needs to be increased. The larger dust particles have different shapes due to different materials and shapes, so that pits generated by impact are different in shapes, the polishing effect on the ground is different, and the polishing uniformity of the polishing equipment on the ground is influenced.

A control method of high-precision grinding equipment with a multistage electromagnetic separation device comprises the following steps: after the grinding equipment is started, the following steps are carried out: the method comprises the following steps: the image detection equipment records the polishing condition of the ground and transmits information to the processor; step two: after the processor carries out intelligent analysis and calculation according to the information transmitted by the image detection equipment, if the proportion of the spherical pits in the pits newly generated on the ground is reduced, the advancing speed of the grinding equipment is adjusted through the controller until the grinding degree of the ground reaches a standard horizontal line after grinding, and meanwhile, the power of the first rotating motor is increased through the controller until the proportion of the spherical pits in the pits newly generated on the ground returns to the standard proportion.

Hardness and the material on different positions on ground department are different, can lead to in different positions, and the quantity and the size of the dust granule of the production of polishing are different, need adjust agitating unit's power correspondingly this moment, prevent that great dust granule from getting into the shot-blasting wheel, cause the influence to the effect of polishing of equipment of polishing. Ideally, the steel shots are spherical, and the proportion of spherical pits in newly generated pits on the ground is one hundred percent.

The friction in the stirring device comes from two aspects: firstly, friction is generated due to different motion directions; the second is the friction generated by the difference of the inner and outer movement speeds. The steel shot and the large-particle dust particles in the recovery box 4 fall into the stirring device, and rub against each other under the action of the stirring shaft and the rotating blades 52, so that the surface of the steel shot becomes smooth, and the dust particles are broken into smaller particles. The air current that air jet fan 54 produced gets into agitating unit by air jet 56, blows the top with the less dust granule of bottom, falls to the upper surface of shot and dust granule under the effect of filter screen, improves agitating unit and to the crushing effect of great dust granule. The first rotating motor is a one-way motor, and rotates at intervals, so that mutual friction in the stirring device can be increased. Since the dust particles entering the stirring device are not removed by the dust removal fan 2, the dust particles have a large volume and mass, and therefore, the dust particles need to be conveniently separated after being crushed. The rotating blades 52 are arranged to be inclined downwards along the rotating direction of the stirring shaft 51 and matched with the air injection pipeline 53, and are used for lifting the steel shots and the dust particles upwards and preventing the steel shots and the dust particles from being accumulated at the bottom.

The situation of the ground to be processed is recorded through the image detection device 7, data are intelligently analyzed through the processor, if the proportion of spherical pits formed by the impact of the steel shots is reduced, the dust particles are not completely crushed by the stirring device, the larger dust particles and the steel shots are thrown out by the shot blasting wheel, and the stirring speed of the stirring device needs to be increased. The larger dust particles have different shapes due to different materials and shapes, so that pits generated by impact are different in shapes, the polishing effect on the ground is different, and the polishing uniformity of the polishing equipment on the ground is influenced.

The working process of the embodiment is as follows: the steel shots in the shot hopper 6 are thrown out at a high speed by the shot blasting wheel, the ground is polished after passing through the shot blasting channel, and then the steel shots carry dust particles to enter the recovery box 4 under the action of the recovery channel. Smaller dust particles enter the collecting device 3 under the action of the dust removal fan 2. And opening the first opening and closing structure to enable the steel shots and dust particles in the recovery box 4 to enter the stirring device through the communicating pipeline, and then closing the first opening and closing structure. The stirring device polishes the surface of the steel shot and enables dust particles to be broken and reduced.

The steel shots and dust particles in the stirring device enter the electromagnet separation structure through the second through hole, most of the dust particles are sucked away by the air suction fan and enter the collecting device 3, the steel shots are adsorbed by the electromagnet 510 and rotate under the driving of the central shaft 58, and the dust particles are separated from the steel shots through centrifugal force. The dust particles in the electromagnet separation structure are brought into the air suction pipeline 512 by the airflow blown out by the air blowing fan under the action of the guide surface. Finally, the power supply of the electromagnet 510 is cut off, so that the steel shots on the surface of the electromagnet fall off and enter the shot hopper 6 under the action of the guide surface. The air flow blown by the blowing fan passes through the air vents 511 to clean the dust particles in the area between the auxiliary plates.

Hardness and the material on different positions on ground are different, can lead to in different positions, and the quantity and the size of the dust granule that the shot-blasting produced are different, need adjust agitating unit's power correspondingly this moment, prevent that great dust granule from getting into the shot-blasting wheel, cause the influence to the effect of polishing of the equipment of polishing. Ideally, the steel shots are spherical, and the proportion of spherical pits in newly generated pits on the ground is one hundred percent. While the larger dust particles are non-spherical in shape, the impact-generated pits are also non-spherical pits. The existence of great dust granule can make the equipment of polishing unstable to the efficiency of polishing on ground, changes the translation rate of the equipment of polishing, can balance it.
