[0002] Diamond purification refers to the process of extracting pure diamonds from diamond ore containing impurities. When purifying diamonds, the ore containing diamonds must first be crushed into smaller particles, and then the crushed diamonds must be cleaned by acid washing to remove impurities on the surface of the diamonds (such as graphite, metal catalysts and pyrophyllite, etc.). In order to improve the efficiency of diamond purification operations, related technologies often use purification equipment to perform integrated crushing and cleaning operations on diamonds.

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figures 1 to 3 As shown, the diamond production purification device of the present invention comprises a pickling cylinder 1, in which a cleaning liquid for pickling materials is injected, a feed port 11 and a discharge piece are arranged on the pickling cylinder 1, a crushing chamber 21 is arranged in the pickling cylinder 1, the feed port 11 and the discharge piece are both connected with the inside of the crushing chamber 21, the material to be processed enters the crushing chamber 21 from the feed port 11, and is crushed and pickled in the crushing chamber 21, and the material after the crushing and pickling operation is discharged and collected from the discharge piece, and enters the subsequent processing process.

[0026] like Figures 3 to 5As shown, the bottom of the crushing chamber 21 is rotatably matched with a bottom plate 22, and a plurality of through holes are evenly opened on the bottom plate 22. The internal space of the crushing chamber 21 is connected with the internal space of the pickling cylinder 1 through the through holes, and the cleaning liquid in the pickling cylinder 1 enters the crushing chamber 21 through the through holes. A fixed part 24, a movable part 23 and a driving part 2 are arranged in the crushing chamber 21. The fixed part 24 and the movable part 23 are both in a plane scroll shape. The bottom end of the movable part 23 is in contact with the upper end surface of the bottom plate 22, and a gap is left between the bottom end of the fixed part 24 and the upper end surface of the bottom plate 22. The gap between the fixed part 24 and the bottom plate 22 is used to screen the crushed material. After the material is crushed to a qualified size, it can pass through the gap between the fixed part 24 and the bottom plate 22 to a position away from the center of the bottom plate 22. The driving member 2 is arranged to move, and there is a gap between the fixed member 24 and the movable member 23. The driving end of the driving member 2 is connected to the vortex center of the movable member 23. The driving member 2 drives the movable member 23 to rotate around its vortex center. The driving member 2 can be a motor. When the driving member 2 drives the movable member 23 to rotate, the gap between the movable member 23 and the fixed member 24 changes. By controlling the reciprocating forward and reverse rotation of the driving member 2, the size of the gap between the movable member 23 and the fixed member 24 can be repeatedly adjusted, and the material entering between the movable member 23 and the fixed member 24 can be squeezed and crushed. The bottom plate 22 is matched with the crushing chamber 21 for rotation. When the bottom plate 22 rotates relative to the crushing chamber 21, the material falling on the bottom plate 22 is driven to move to between the fixed member 24 and the movable member 23.

[0027] like Figures 4 to 7 As shown, a transmission assembly is also provided at the bottom end of the bottom plate 22, and the transmission assembly is connected to the driving member 2 and the bottom plate 22 at the same time. The transmission assembly is used to drive the bottom plate 22 to rotate forward or reversely synchronously with the movable member 23. The state in which the movable member 23 rotates forward and approaches the fixed member 24 to extrude the material is its working state, and the state in which the movable member 23 rotates reversely and moves away from the fixed member 24 is its reset state. Figure 5 is the relative position relationship between the movable part 23 and the fixed part 24 in the working state, Figure 4 is the relative position relationship between the movable part 23 and the fixed part 24 in the reset state, and the discharge end of the feed port 11 and Figure 4 The position of area A is relative, and the material to be processed falls into area A. The reverse rotation direction of the bottom plate 22 is always consistent with the forward rotation direction of the movable part 23. When the bottom plate 22 rotates forward, the material falling into area A is continuously transported to between the fixed part 24 and the movable part 23.

[0028] The transmission assembly includes a gear 3, a movable wheel 31 and a transmission part 221. The gear 3 is rotatably arranged in contact with the bottom end surface of the base plate 22. The gear 3 is coaxial with the base plate 22. The gear 3 is fixed relative to the driving end of the driving member 2. The gear 3 rotates synchronously with the movable member 23. The transmission part 221 is annularly arranged at the bottom of the base plate 22. The inner ring of the transmission part 221 is toothed. The movable wheel 31 is arranged between the gear 3 and the transmission part 221. The movable wheel 31 is meshed with the gear 3 and the transmission part 221 at the same time. The movable wheel 31 is connected to a connecting member, which includes a connecting part 311 and a connecting shaft 312. The connecting shaft 312 is rotatably matched with the connecting part 311. The movable wheel 31 is fixedly sleeved on the connecting shaft 312. The transmission assembly also includes a limiting structure, which is used to limit the relative rotation state of the movable wheel 31 and the connecting shaft 312.

[0029] The limiting structure includes a limiting member 32, a ratchet and a ratchet bar 313. The ratchet bar 313 is slidably matched with the connecting portion 311. There are multiple ratchets, each of which is circumferentially arranged on the connecting shaft 312. The connecting shaft 312 is unidirectionally slidably matched with the ratchet bar 313 through each ratchet. When the ratchet and the ratchet bar 313 are relatively locked, the connecting shaft 312 does not rotate relative to the connecting portion 311, and the movable wheel 31 is also unable to rotate. When the gear 3 rotates forward with the movable member 23, the movable wheel 31 is in a locked state. Under the meshing action of the movable wheel 31 and the gear 3, the movable wheel 31 slides along an arc path, and drives the bottom plate 22 to rotate in the same direction as the movable member 23 under the action of the transmission part 221, that is, when the movable member 23 rotates forward to extrude the material, the bottom plate 22 rotates to drive the material falling in the A area to move to the area between the movable member 23 and the fixed member 24, so that the falling material can be fully crushed. The limiting member 32 is arranged between the gear 3 and the connecting portion 311. The limiting member 32 and the bottom plate 22 are relatively rotated and matched. The limiting member 32 can be annular. Specifically, the limiting member 32 can be fixed relative to the crushing chamber 21. At least two legs 211 are fixed to the outer wall of the crushing chamber 21. Each leg 211 is fixed relative to the bottom of the pickling cylinder 1. Each leg 211 extends from the lower side of the bottom plate 22 in the direction close to the axial direction of the crushing chamber 21 and is fixed to the limiting member 32. The limiting member 32 is also provided with an arc-shaped guide groove 321. The shape of the guide groove 321 matches the sliding path of the movable wheel 31, and the center of the guide groove 321 coincides with the center of the bottom plate 22 and the gear 3. The limiting member 32 is provided with a limiting Part 1 322 and limit part 2 323, the limit part 1 322 and the limit part 2 323 are respectively opposite to the two ends of the guide groove 321, that is, the limit part 1 322 and the limit part 2 323 are respectively located at the two ends of the sliding path of the movable wheel 31, and the movable wheel 31 slides from the limit part 1 322 to the limit part 2 323 when it is in the locked state, and the limit part 1 322 and the limit part 2 323 are in active contact with the ratchet bar 313, and the limit part pushes the ratchet bar 313 to engage with the ratchet when contacting the ratchet bar 313, so that the movable wheel 31 enters the locked state, and the limit part 2 323 pushes the ratchet bar 313 to disengage from the ratchet when contacting the ratchet bar 313, and the movable wheel 31 returns to a rotatable state.

[0030] The connecting part 311 is also connected to a guide member 324, which is in the shape of an arc rod. The shape of the guide member 324 is also adapted to the sliding path of the movable wheel 31. The guide member 324 is slidably matched with the second limiting part 323. The guide member 324 is provided with an elastic member 325 between the second limiting part 323 and the connecting part 311. When the connecting part 311 is close to the second limiting part 323, the elastic member 325 is squeezed. The elastic member 325 can be a spring.

[0031] When the driving member 2 drives the movable member 23 and the gear 3 to rotate in the positive direction, the movable wheel 31 slides from the position of the limiting part 1 322 to the position of the limiting part 2 323 in a locked state. During the process of the movable wheel 31 approaching the limiting part 2 323, the elastic member 325 is continuously squeezed and the elastic member 325 is forced to accumulate force. During the positive sliding process of the movable wheel 31, the bottom plate 22 is driven to rotate positively through the transmission part 221, and the materials falling on the bottom plate 22A area are continuously transported to between the movable member 23 and the fixed member 24, so that the materials are fully squeezed and crushed. The connecting member moves with the movable wheel 31, and the ratchet bar 313 and the limiting part 323 are connected. When the two gears 323 abut against each other, the ratchet on the relative connecting shaft 312 disengages, releasing the restriction on the rotation of the connecting shaft 312 and the movable wheel 31. In the process of crushing the material, the driving member 2 will reciprocate and drive the movable member 23 to rotate forward and reversely. When the driving member 2 drives the movable member 23 and the gear 3 to rotate in the reverse direction, the movable wheel 31 rotates around its axis under the meshing action with the gear 3, and pushes the bottom plate 22 to rotate in the reverse direction relative to the gear 3 through the movable part. That is, in the process of the movable member 23 repeatedly forward and reversely crushing the material, the bottom plate 22 always keeps rotating forward and continuously transports the material to between the movable member 23 and the fixed member 24. Under the elastic force of the elastic member 325, the movable wheel 31 will also slide along the guide groove 321 during the forward rotation until the ratchet bar 313 abuts against the limiting portion 1 322, and the limiting portion 1 322 pushes the ratchet bar 313 to re-engage with the ratchet on the connecting shaft 312, thereby locking the rotation of the connecting shaft 312 and the movable wheel 31, that is, the movable wheel 31 moves from the limiting portion 1 322 to the limiting portion 2 323 in a sliding state, and simultaneously moves from the limiting portion 2 323 to the limiting portion 1 322 in a rotating and sliding state.

[0032] After the material is crushed to a qualified size, it moves to the edge of the bottom plate 22 through the gap between the fixing member 24 and the bottom plate 22, and enters the discharging member after the bottom plate 22 rotates to be opposite to the discharging member. In order to further improve the pickling effect of the crushed material, a cleaning component is also provided in the crushing chamber 21. The cleaning component includes a lifting member 26 and a scrubbing member 25. The scrubbing member 25 is located on the outside of the fixing member 24. The protruding end of the lifting member 26 is connected to the upper side of the scrubbing member 25. The lifting member 26 drives the scrubbing member 25 to move in the crushing chamber. The lifting member 26 can be a cylinder and moves longitudinally in the crushing chamber 21. The crushed material moves to the outside of the fixing member 24 and enters the lower side of the scrubbing member 25. The lifting member 26 drives the scrubbing member 25 to move downward until the scrubbing member 25 presses on the upper side of the material. The bottom plate 22 rotates relative to the scrubbing member 25, so that the small particles between the scrubbing member 25 and the bottom plate 22 are further scrubbed and cleaned, thereby improving the cleaning effect on the material. In order to further improve the cleaning effect, the bottom end face of the scrubbing member 25 can also be provided with convex patterns.

[0033] In order to facilitate the small particle material to slide toward the edge of the bottom plate 22, the thickness of the bottom plate 22 can be reduced in the direction close to its edge. The discharge member includes a barrel 12 and a screw conveyor shaft 13. The screw conveyor shaft 13 is arranged in the barrel 12 and is used to convey the material in the barrel 12 from bottom to top. A discharge port 14 is provided on the upper side of the barrel 12, and the discharge port 14 is inclined downward in the direction away from the barrel 12.

[0034] The diamond production purification device provided by the present invention can promote the full contact between the crushed small particles and the pickling liquid while crushing the diamond ore, thereby improving the cleaning effect of the diamond ore during purification treatment.
