The ejection of compact subassembly includes annular box 107, discharging pipe 112, has seted up annular groove 106 on the crocus case 101 inner wall, and the bottom slope sets up in annular groove 106, and annular box 107 cup joints outside crocus case 101, has seted up out powder hole 111 on the annular groove 106 inner wall, and the one end setting of discharging pipe 11 is at the interior bottom of annular box 107, and the other end setting of discharging pipe 11 is at the top in adsorption tank 201. It should be noted that, through setting up the powder outlet 111, the kaolin particles after grinding can be sieved, so that only the kaolin particles with qualified size can enter the ring box 107 through the powder outlet 111, and the unqualified kaolin particles slide down into the pulverizing box 101 along the inclined bottom of the ring groove 106.

The driving assembly comprises a gear ring 102, a gear 104 and a bracket 103, wherein the gear ring 102 is fixedly arranged at the upper end of the grinding box 101, the gear 104 is rotatably connected to the lower end of the bracket 103, the gear 104 is meshed with the gear ring 102, the gear 104 is fixedly connected with a grinding wheel 105 through a connecting rod, and the bracket 103 is fixedly connected with a three-way pipe 108. It should be noted that, by arranging the driving assembly, the grinding wheel 105 can rotate along the inner wall of the annular groove 106, and can rotate at the same time, so that kaolin particles thrown onto the inner wall of the annular groove 106 can be ground, and compared with a mode of grinding through a grinding disc, the device can more fully grind the kaolin particles; more remarkably, in the device, the revolution speed and the rotation speed of the grinding wheel 105 are controlled by the three-way pipe 108, so that the faster the rotation speed of the three-way pipe 108 is, the more kaolin particles thrown out in unit time are, the faster the grinding wheel 105 rotates, and more kaolin particles can be ground in unit time, therefore, the device can also automatically adjust the rotation speed of the grinding wheel 105 according to the throwing-out speed of the kaolin particles so as to ensure that the kaolin particles can be fully ground.

In the invention, the kaolin particle raw material with larger size can be conveyed into the three-way pipe 108 from the feeding pipe 110, and at the same time, the double-shaft motor 6 is started and drives the negative pressure fan 207, the reciprocating screw 208, the rotating shaft 5, the three-way pipe 108 and the stirring shaft 308 to rotate.

In the rotating process of the three-way pipe 108, the kaolin particle raw materials falling into the three-way pipe can be continuously thrown out from two ends, the kaolin particle raw materials can be thrown into the annular groove 106 under the action of centrifugal force, the three-way pipe 108 can drive the support 103 fixedly connected with the three-way pipe to rotate at the same time, the support 103 can drive the gears 104 on the support to rotate around the feeding pipe 110, and in the process, the gears 104 continuously run along the inner wall of the gear ring 102, so that the gears 104 can rotate and drive the grinding wheel 105 below the gears to rotate.

Therefore, the grinding wheel 105 can rotate along with the rotation of the support 103 and can also rotate, so that the raw material of kaolin particles thrown to the inner wall of the annular groove 106 can be fully ground, the qualified powdered kaolin particles pass through the powder outlet 111 and enter the annular box 107, and the unqualified kaolin particles fall back into the grinding box 101 along the inclined bottom of the annular groove 106 and are continuously pushed into the annular groove 106 for grinding by the kaolin particles thrown out of the three-way pipe 108.

Therefore, the device can screen the ground kaolin particles to discharge the qualified kaolin particles, and can grind the unqualified kaolin particles again.

After the negative pressure fan 207 rotates, a negative pressure is continuously generated in the discharge pipe 112, so that the kaolin particles ground through the powder outlet 111 are sucked into the adsorption tank 201 from the annular tank 107. The kaolin particles entering the adsorption tank 201 are blocked by the conical screen 205, air can pass through the conical screen 205 and then is discharged from the outlet pipe 203, while the kaolin particles are blocked at the upper end surface of the conical screen 205, slide downwards under the action of gravity, flow into the outlet pipe 203 through the material guide pipe 204, and finally are discharged at a high speed along with the air flow.

In the process, the reciprocating lead screw 208 continuously rotates, and under the action of the limiting rod 210, the lead screw nut 209 on the reciprocating lead screw 208 moves up and down in a reciprocating manner, so that the magnetic force plates 202 on two sides of the lead screw nut 209 also move up and down together. On one hand, the magnetic plate 202 moving up and down continuously impacts the conical filter screen 205 to cause the kaolin particles trapped on the conical filter screen 205 to slide down; on the other hand, during the up-and-down movement of the magnetic plate 202, the magnetic plate continuously enters and exits the spiral coil 206, so that the magnetic flux inside the spiral coil 206 changes, and finally an induced current is generated in the spiral coil 206, and after the magnetic plate 202 is completely moved out of the spiral coil 206, the magnetic flux inside the spiral coil 206 is zero, and at this time, no induced current is generated. The spiral coil 206 thus intermittently generates current as the magnetic plate 202 moves up and down.

Therefore, the electromagnetic spring 304 electrically adjacent to the helical coil 206 is intermittently energized, i.e., the electromagnetic spring 304 is continuously energized and de-energized, so that the electromagnetic spring 304 is continuously stretched and contracted, thereby driving the telescopic bellows 303 to stretch and contract and pushing the discharge pipe 305 below to move up and down in the stirring tank 301. It should be noted that, when the present apparatus is applied to: when a large amount of kaolin particles and surfactant are treated at one time, and the resistance to the up-and-down movement of the spoiler 307 is large, and the current generated by the spiral coil 206 is difficult to extend and contract the electromagnetic spring 304, the electromagnetic spring 304 can be coupled with an amplifying circuit to assist the operation of the device.

And kaolin particle and air current will be along outlet duct 203 during the flexible bellows 303 of income and row material pipe 305, each bin outlet 306 discharge on row material pipe 305 lateral wall can be followed finally, then row material pipe 305 is at the in-process that reciprocates, can make and discharge in each different degree of depth positions department of agitator tank 301 from each bin outlet 306 kaolin particle, thereby can make the kaolin particle after the grinding can the homodisperse in agitator tank 301 surfactant active everywhere, when (mixing) shaft 308 drive stirring vane 302 rotates, can make kaolin particle and surfactant active intensive mixing even in short time, the mixing efficiency has been improved greatly.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
