Description

TECHNICAL FIELD

[0002] Barite is the most common mineral of barium, and its composition is barium sulfate.

[0028] Working principle: the gravity direction of the device is the direction from the crusher 107 to the bottom plate 101, when using the device, the material is sent into the crusher 107, and the crusher 107 is driven to rotate by the crushing motor, so that the crusher 107 preliminarily crushes the material, and the crushed material enters the grinding box 103 under the action of gravity, and then falls on the shaking plate 205, if the crushed material can pass through the primary filter holes on the shaking plate 205, it enters the chamber formed by the shaking plate 205 and the grinding arc plates 307 for further crushing and grinding, if it cannot pass through the shaking plate 205, it will stay on the shaking plate 205, at this time, the main motor 201 is started to drive the first gear 202 to rotate counterclockwise to drive the rotating gear 206, at this time, the rotating gear 206 is clamped by the clamping plate 207 in the initial state, so that the first gear 202 rotates to drive the second gear 211, the rotating gear 206 and the first internal gear 301 to rotate counterclockwise. Figure 6 Figure 6

[0029] ​​When the rotating gear 206 rotates, it will drive the shaking plate 205 and the pressure rod 218 to rotate around the first gear 202 shaft, which makes the bayonet plate 207 slide on the pressing ring 212. When the pressure rod 218 rotates, it will also press the sliding baffle 216, so that the sliding baffle 216 moves away from the secondary bottom column 108 and stretches the baffle spring 217. At the same time, the inclined pressing block on the pressing ring 212 will press the bayonet plate 207, which will drive the bayonet plate 207 to move away from the sealing block 204. The purpose is to make the bayonet plate 207 be pressed for a predetermined time, so that the bayonet plate 207 is out of contact with the rotating gear 206, so that the rotating gear 206 can rotate freely. At this time, the sliding baffle 216 will pull the shaking plate 205 and the pressure rod 218 back to the initial position through the baffle spring 217, and after returning to the initial position, the bayonet plate 207 will be in contact with the rotating gear 206 and fit. At this time, the rotating gear 206 will repeat the above movement. The purpose is to make the material on the shaking plate 205 that does not pass through the primary filter hole be lifted by the shaking plate 205, and be sent to the grinding arc plate 307 near the grinding box 103 through the shaking plate 205, so that the material enters the conveying pipe 104 through the inclined pipe 105, so that the spiral shaft 106 brings the material into the crusher 107 through the material outlet on the spiral shaft 106, so that the crusher 107 crushes the material again.

[0030] When the first internal gear 301 rotates, it will drive the rotating pressure plate 303 to move together with the rotating sliding plate 304, and the rotating sliding plate 304 will slide on the grinding box 103 around the first gear 202 shaft. When the rotating sliding plate 304 rotates to the limit position, it will be locked, and then the rotating sliding plate 304 will press the rotating pressure plate 303 to drive the first torsion spring to rotate, so that the rotating pressure plate 303 avoids the rotating sliding plate 304. After that, the rotating sliding plate 304 will be driven by the sliding plate spring 305 to return to the initial position. The purpose of the sliding of the rotating sliding plate 304 is to drive the grinding arc plate 307 to rotate around the first gear 202 shaft together, so that the grinding arc plate 307 constantly rubs the material between the grinding arc plate 307 and the fixed filter plate 308 when rotating. At this time, the material on the coarse filter hole will also be constantly rubbed with the fixed filter plate 308, so that the material can be further refined, so that the material passes through the grinding filter hole on the fixed filter plate 308.

[0031] When the rotating gear 206 is out of contact with the bayonet plate 207, the first gear 202 is also rotating, so when the sliding baffle 216 pulls the rotating gear 206 to move, the second gear 211 will be driven by the first gear 202 to rotate, and when the second gear 211 rotates, it will drive the precision breaking rod 219 to further break the material between the shaking plate 205 and the cavity formed by the grinding arc plate 307. It is worth mentioning here that the first internal gear 301 will be accelerated at this time, so that the intermediate ring 302 continues to rotate for a distance.

[0032] When the material in the cavity formed by the shaking plate 205 and the grinding arc plate 307 gradually accumulates, the auxiliary motor 215 is started when the bayonet plate 207 is out of contact with the rotating gear 206, and the auxiliary motor 215 drives the pressing ring 212 to move towards the main motor 201 through the threaded rod 213, so that the pressing ring 212 continues to press the bayonet plate 207, so that the rotating gear 206 is no longer stuck, and when the first gear 202 rotates at this time, it will only swing the grinding arc plate 307 through the intermediate ring 302 and the rotating slide plate 304, and will also drive the precision breaking rod 219 to rotate continuously in the cavity, so that the material can be quickly broken and ground, and the ground material will leave the device through the material outlet on the grinding box 103.
