Background
The graphite is formed by stacking planar carbon atoms which are orderly arranged in a honeycomb shape layer by layer, and the interlayer acting force of the graphite is weak, so that the graphite is easy to be mutually stripped to form a flake graphite sheet, namely crystalline flake graphite. The flake graphite is a mineral easy to float, and the high grade of graphite concentrate needs to be improved to achieve and protect the flake, so that the graphite ore needs to be subjected to monomer dissociation, and the aim can be achieved only by multi-section ore grinding, pre-separation and multi-section concentration during the monomer dissociation. The main reasons for the damage of the scale and the low taste of the final concentrate are that the scale is damaged and the final concentrate is not high in taste, most of the existing graphite concentrate regrinding equipment adopts a ball mill, an ore grinding medium is arranged in a cylinder of the ball mill, the ore grinding medium is driven to fall due to self weight after being driven to a certain height by the rotation of the cylinder, so that the ore arranged in the cylinder is under the action of medium impact force, and on the other hand, the ore grinding medium generates extrusion and grinding stripping force on the ore between the ore grinding medium and a cylinder contact zone thereof due to the revolution and rotation of the ore grinding medium in the cylinder along the axis of the cylinder, thereby dissociating the graphite into monomers. However, because the internal grinding medium of the ball mill is in point contact with the material when falling, the impact force is strong, and the material is cracked and broken under the action of the impact force, the ball mill is used as graphite concentrate regrinding equipment to dissociate graphite into monomers and simultaneously cause flake damage. Since graphene is formed by regional deterioration of carbon, accompanying minerals of graphite mainly include impurities such as clay, quartz, pyrite, carbonate and the like. Therefore, the accompanying clay, quartz, carbonate and the like cannot be separated without monomer dissociation, and it is difficult to improve the taste of the graphite concentrate without separation.

On the basis of not considering the transmission stability, the driving device 1 can also adopt a chain transmission mode, a gear transmission mode and the like.
It should be understood that, where the rotating shaft 2 and the cylinder 7 are provided, that is, the rotating shaft 2 is rotatably provided on the cylinder 7 through a bearing, a sealing device is provided between the bearing and the rotating shaft 2, and the sealing device ensures that the mixed slurry in the cylinder 7 does not leak from the sealing device, the sealing device is a shaft end sealing manner using a conventional sealing device, such as a stirrer, and the detailed structure of the sealing device is not described in detail.
The stripping part 4 and the rubbing part 3 are positioned in the inner cavity of the cylinder 7 and correspond to the space between the feed inlet 5 and the discharge outlet 12, the stripping part 4 and the rubbing part 3 are sequentially arranged on the rotating shaft 2 at intervals along the direction from the feed inlet 5 to the discharge outlet 12, the stripping part 4 is provided with a plurality of stripping teeth 401, the stripping teeth 401 are circumferentially arranged at intervals along the stripping part 4, the tooth root part of each stripping tooth 401 extends to the tooth tip part through a curved path to form a first curved tooth, and the included angle between each first curved tooth and the horizontal plane is between 0-5 degrees, wherein the angle range refers to the included angle between the tangent line of any point on each first curved tooth and the horizontal plane, and the angle represents the deformation degree of the tooth root part of each stripping tooth 401 extending to the tooth tip part. When the stripping teeth 401 are at 0 degree, the stripping teeth 401 are entirely positioned in a horizontal plane, and the plurality of stripping teeth 401 are arranged in a cyclone shape in the circumferential direction of the rotating shaft 2, so that the length of the stripping teeth 401 can be increased by the cyclone shape arrangement, the contact point with graphite ore is increased, and the friction probability between the graphite ore and the stripping teeth 401 is increased; simultaneously, the whirlwind form sets up and can also make to peel off piece 4 when rotating along with pivot 2 softer, and it is the tangential direction of contact point with graphite ore atress direction when bumping, further reduces the breakage to the graphite scale, the scale structure of the protection graphite of great degree. At 5 degrees or even less than 5 degrees, the shape of the first curved-surface-shaped tooth is similar to the shape of a fan blade of a fan, the maximum included angle between the tangential direction of the arc-shaped tooth tip and the horizontal plane is 5 degrees, and under the angle, when the stripping tooth 401 is contacted with the graphite ore, the component force of the action force of the stripping tooth 401 on the graphite ore along the horizontal direction is larger (namely, the cutting force), so that the stripping tooth can be ensured to mainly perform stripping and cutting functions, and most of the graphite ore is stripped into scaly graphite; moreover, it can also play the effect that promotes mixed thick liquids and flow from feed inlet 5 to discharge gate 12 at the pivoted in-process, because can form the vortex at the in-process that stripping element 4 rotated, be located the formation vortex space of feed inlet 5 one side, can give the mixed thick liquids simultaneously to the thrust that discharge gate 12 promoted the material have feed inlet 5 to promote to push to discharge gate 12.
The abrading element 3 is provided with a plurality of abrading teeth 301, the plurality of abrading teeth 301 are arranged at intervals along the circumferential direction of the rotating shaft 2, the root of each abrading tooth 301 extends to the tip of the tooth through a curved path to form a second curved tooth, and the included angle between the second curved tooth and the horizontal plane is 20-50 degrees. And 20-50 degrees is the included angle between the tangent direction of any point on the second curved surface-shaped tooth and the horizontal plane, and represents the deformation degree of the root part of the scrubbing tooth 301 extending to the tip part of the tooth. And, whole second curved surface shape tooth reduces gradually by the tangent line of lower supreme difference and the contained angle between the horizontal plane, and simultaneously, whole second curved surface shape tooth reduces gradually by the tangent line of root of tooth to the tooth point difference and the contained angle between the horizontal plane, can slow down its upward movement's speed like this at the in-process of rubbing, improves the effect of rubbing. As a whole, the angle between the grinding tooth 301 and the horizontal plane at this angle is larger than the angle between the stripping tooth 401 and the horizontal plane, so that the grinding tooth 301 can be ensured to mainly perform the grinding function, because the graphite ore is in contact with the grinding tooth 301 of the grinding tooth 301 at this angle, the graphite ore has the power of moving upwards under the condition that the graphite ore is given a certain initial speed by the stripping tooth 401, the component force of the graphite ore acting on the grinding tooth 301 along the grinding plane is larger (namely, the friction force) under this angle of the grinding tooth 301, and the friction between the graphite ore and the grinding tooth 301 can be ensured to be the sliding friction, so that the graphite ore is ensured to continuously rise in friction, and the main grinding function is achieved.
Can realize through above-mentioned scheme that the material can be in proper order from feed inlet 5 to discharge gate through peeling off 4, rub piece 3, utilize graphite ore to give certain initial velocity simultaneously after peeling off of piece, realize the process of rubbing while upward movement under the effect of rubbing piece, then from the 12 ejection of compact of discharge gate, accomplish graphite stripping and the flake graphite or the graphite monomer after dissociation at the material from the in-process of feed inlet 5 to discharge gate 12 and scrub, improve the taste of concentrate graphite. The principle is that the stripping teeth 401 on the stripping piece 4 rotate to generate circumferential cutting force to strip graphite in mixed slurry, although graphite ores in the mixed slurry entering the cylinder 7 are disordered, the stripping teeth 4 always strip the graphite ores in the rotating process due to the rotation of the steel balls and the stripping piece 4, the graphite ores are stripped in a large probability due to the fact that the steel balls and the stripping piece 4 rotate for a plurality of turns repeatedly, and meanwhile, when the stripping teeth 401 of the stripping piece 4 touch the graphite ores, the graphite ores can transversely move to reduce the transverse impact force of the stripping teeth 401, so that the scale structure of the graphite is protected, meanwhile, the surface of the separated scale graphite is continuously rubbed under the action of the rubbing piece 3, and the taste of the concentrate graphite is improved.
In fact, the driving force of the mixed slurry from the feeding port 5 to the discharging port 12 is realized by continuously adding materials into the cylinder 7, and the materials are continuously added into the cylinder 7, so that the materials are driven towards the discharging port 12. The speed and the amount of the materials added can be controlled by arranging the switch valve 6 at the feeding hole 5, the adding amount of the materials can influence the stay time of the materials in the cylinder 7 at the stripping part 4 and the grinding part 3, and further influence the stripping and grinding effects of the graphite ores, so that the switch valve 6 can be opened or closed according to specific conditions during specific operation.
Further, between the adjacent peeling member 4 and the abrading member 3 as in fig. 1, the tooth root to tooth tip portions of the peeling teeth 401 on the peeling member 4 extend in the axial direction toward the opposite direction to the direction in which the tooth root to tooth tip portions of the abrading teeth 301 on the abrading member 3 extend in the axial direction, that is, the extending direction of the tooth root to tooth tip portions of the peeling teeth 401 is opposite to the extending direction of the tooth root to tooth tip portions of the abrading teeth 301 as viewed in the axial direction of the rotating shaft 2.
Alternatively, as shown in fig. 7, when viewed in the axial direction of the rotating shaft 2 between the adjacent stripping members 4 and the abrading member 3, the extending direction of the tooth root to the tooth tip of the stripping tooth 401 on the stripping member 4 is the same as the extending direction of the tooth root to the tooth tip of the abrading tooth 301 of the abrading member 3.
When the graphite ore moves from bottom to top in the cylinder 7, the graphite ore is given a certain initial speed after being stripped by the stripping teeth 401, because the direction between the rubbing teeth 301 and the stripping teeth 401 is opposite, the graphite ore can be reversed when entering the rubbing piece 3, and pre-rubbing action can be generated between graphite monomers and between the graphite monomers and the steel ball before entering the rubbing piece 3 during reversing. When the direction is changed, if the density of impurities on the graphite monomer is greater than that of the graphite monomer, the surface of the graphite monomer with more impurities tends to face downwards, and the surface of the graphite monomer with more impurities contacts with the upstream surface of the grinding teeth 301 to a greater extent, so that large-particle impurities are basically ground, and the grinding effect is improved; in addition, the graphite ore slightly reduces the upward movement speed during the reversal, thus giving the grinding teeth 301 a longer time to grind. It can be seen that the direction of extension from the tooth root to the tooth tip of the stripping tooth 401 of the stripping element 4 and the direction of extension from the tooth root to the tooth tip of the scrubbing tooth 301 of the scrubbing element 3 are particularly suitable for the case of a greater impurity density than graphite ore.
Meanwhile, in the moving process of the graphite ore from bottom to top in the cylinder 7, a certain initial speed is given after the stripping teeth 401 strip, because the directions of the grinding teeth 301 and the stripping teeth 401 are the same, if the density of impurities on the dissociated graphite monomer is smaller than that of the graphite monomer, the surface with more impurities of the graphite monomer inclines upwards, at the moment, the surface with more impurities of the graphite monomer can be in contact with the upstream surface of the grinding teeth 301 to a greater extent, large-particle impurities are basically ground, and therefore the grinding efficiency is improved.
Further, in an embodiment or based on the above embodiment, the stripping elements 4 are at least two, in this embodiment, the stripping elements 4 are two, and the two stripping elements 4 are arranged at intervals in the axial direction of the rotating shaft 2, so that the arrangement of the stripping elements 4-the rubbing elements 3 is formed on the rotating shaft 2 in the direction from the feeding port 5 to the discharging port 12, the stripping teeth 401 on the two stripping elements 4 are arranged in the same direction, the probability of rubbing between the graphite ore and the stripping elements 4 can be increased by the two stripping elements 4, when the graphite ore cannot be stripped by the first stripping element 4, the graphite ore is likely to be stripped by the second stripping element 4, and the two stripping elements 4 jointly function to increase the probability of rubbing between the stripping teeth 401 and the graphite ore, thereby increasing the effect of graphite stripping.
Of course, in some embodiments, the stripping members 4 are not limited to two, but may be one, three, four, etc., and in particular, in the actual design, the arrangement of several stripping members 4 is specifically designed according to the height of the cylinder 7 and the height between the feed opening 5 and the discharge opening 12.
Further, in an embodiment or based on the above embodiment, the number of the rubbing parts 3 is at least two, in this embodiment, two rubbing parts 3 are provided at intervals in the axial direction of the rotating shaft 2, so that the arrangement of the stripping parts 4-the rubbing parts 3 is formed on the rotating shaft 2 in the direction from the feed port 5 to the discharge port 12, or the arrangement of the stripping parts 4-the rubbing parts 3-the stripping parts 4-the rubbing parts 3 is also formed, the rubbing teeth 301 on the two rubbing parts 3 are arranged in opposite directions, so that it can be ensured that the peeled graphite monomer inside the cylinder 7 is rubbed by the first rubbing part 3, and then the peeled graphite monomer is rubbed by the second rubbing part 3 in opposite directions, so that not only the rubbing surface of the graphite monomer is increased, and the second friction and grinding piece 3 also changes the friction and grinding angle of the graphite monomer to a certain extent, so that the graphite monomer can be more comprehensively rubbed and ground.
In addition, in some embodiments, the above-mentioned friction members 3 are not limited to two, but may be provided with one, three, four, etc., and as for the specific arrangement of several friction members 3, the specific design is also required according to the size of the cylinder 7, specifically according to the height of the cylinder 7.
The stripping part 4 and the rubbing part 3 are respectively provided with two functions for further improving the stripping effect and the rubbing effect. Particularly, under the condition that the directions of the rubbing teeth 301 and the stripping teeth 401 are opposite, and the density of impurities is lower than that of the graphite monomer, the surface with more impurities on the graphite monomer is contacted with the water facing surface of the rubbing teeth 301 on the first rubbing piece 3 with lower probability, so that the rubbing effect is not very good, and because the two rubbing pieces 3 are arranged and the directions of the rubbing teeth 301 on the two rubbing pieces are opposite, the graphite monomer is reversed between the two rubbing pieces, and the surface with more impurities on the graphite monomer is contacted with the water facing surface of the rubbing teeth 301 on the second rubbing piece 3 to a greater extent when entering the rubbing teeth of the second rubbing piece 3, so that the two-side rubbing is realized, and the rubbing effect is further improved.
Meanwhile, the stripping part 4 and the rubbing part 3 are respectively provided with two functions for further improving the stripping effect and the rubbing effect. Particularly, under the condition that the directions between the rubbing teeth 301 and the stripping teeth 401 are the same, and the density of impurities is higher than that of a graphite monomer, the surface with more impurities on the graphite monomer is contacted with the upstream surface of the rubbing teeth 301 of the first rubbing piece 3 with a lower probability, so that the rubbing effect is not very good, and because two rubbing pieces 3 are arranged and the directions of the rubbing teeth 301 on the two rubbing pieces 3 are opposite, the graphite monomer is reversed between the two rubbing pieces 3, and the surface with more impurities on the graphite monomer is contacted with the upstream surface of the rubbing teeth 301 of the second rubbing piece 3 to a greater extent when entering the rubbing teeth 301 of the second rubbing piece 3, so that the two-side rubbing is realized, and the rubbing effect is further improved.
Therefore, the two rubbing pieces 3 are arranged, and the rubbing teeth 301 on the two rubbing pieces are arranged in opposite directions, so that comprehensive rubbing can be realized to a greater extent, and the rubbing effect is improved.
Further, in order to improve the strength of the stripping teeth 401, the connecting disc 13 is commonly connected among the stripping teeth 401, the plane of the connecting disc 13 is vertical to the rotating shaft 2, the connecting disc 13 is arranged close to the center of the stripping piece 4, each stripping tooth 401 is divided into an upper tooth part and a lower tooth part, because water, steel balls and graphite ores exist in mixed slurry, the stripping piece 4 has large resistance during rotation, and is easy to bend or deform greatly, and the connecting disc 13 can improve the strength of the stripping teeth 401 and reduce the deformation of the stripping teeth during rotation.
Of course, in alternative embodiments, the connecting plate 13 may be disposed on one or both of the upper end surface and the lower end surface of the stripping member 4.
Further, in the application, the feeding port 5 is located below the discharging port 12, meanwhile, the feeding port 5 and the discharging port 12 are located on two opposite sides of the central line of the cylinder 7, when feeding is performed, materials are fed from the feeding port 5 at the lower portion into the cylinder 7, then a mixture of graphite ore, water and steel balls is continuously added into the cylinder 7, the materials in the cylinder 7 move from bottom to top until the materials are discharged from the discharging port 12 after stripping and grinding are completed, and when the graphite ore enters the stripping part 4 and the grinding part 3, the retention time of the graphite ore at the stripping part 4 and the grinding part 3 is increased due to the gravity effect, so that the stripping and grinding effects of the graphite ore are increased.
However, in some embodiments, the above-mentioned feed opening 5 and discharge opening 12 may be replaced, i.e. the feed opening 5 is located above the discharge opening 12, and correspondingly, in this case, the stripping member 4 and the rubbing member 3 may be replaced, i.e. the stripping member 4 is located above the rubbing member 3.
Furthermore, in the present application, there is a special arrangement for the discharge opening 12, that is, a discharge pipe 11 is connected to the discharge opening 12, the discharge pipe 11 is preferably a stainless steel pipe, an alloy aluminum pipe or other metal pipe having high corrosion resistance, since this reduces the corrosion of the internal water on the tapping pipe 11 and ensures a certain rigid support force, one end of the discharge pipe 11 extends out of the cylinder body 7, the other end extends to a position close to the central shaft of the cylinder body 7 towards the inner cavity of the cylinder body 7, the discharge speed of the graphite monomer can be increased when the discharge pipe 11 extends to the central shaft of the cylinder body 7, so that the dissociated graphite monomer is timely discharged out of the cylinder body 7 after being rubbed and ground, compared with a simple discharging mode of the discharge opening 12 arranged on the wall of the cylinder 7, the distance and the time for the graphite monomer to move to the discharge opening 12 can be shortened, and particularly the distance and the time for the graphite monomer on the side far away from the discharge opening 12 to move to the discharge opening 12 can be shortened.
Furthermore, in order to increase the discharging speed, the discharging pipe 11 is not only provided with an opening on the end face of one end positioned in the cylinder 7, but also provided with a feeding opening 9 on the pipe wall of the discharging pipe 11 positioned in the inner cavity of the cylinder 7, so that the dissociated graphite monomer can be discharged from the opening on the end face of the discharging pipe 11 and the feeding opening 9 on the pipe wall at the same time, and the discharging speed is increased.
Furthermore, in order to prevent the steel balls in the mixture from being discharged out of the cylinder 7 together during discharging, the end faces of the feeding opening 9 on the pipe wall of the discharging pipe 11 and the discharging pipe 11 positioned in the inner cavity of the cylinder 7 are respectively provided with a filter screen 10, the mesh size of the filter screen 10 is set according to the size of the steel balls, and the purpose is to filter the steel balls so that the steel balls are not discharged out of the cylinder 7 together with the graphite monomers.
Further, in an embodiment, the cross-sectional shape of the inner cavity of the cylinder 7 is a polygonal shape to form a polygonal prism section 702 of the inner cavity of the cylinder 7, so that the inner cavity of the cylinder 7 is in a polygonal prism inner cavity structure 8, the stripping element and the rubbing element are disposed on the corresponding polygonal prism section in the cylinder, the polygonal shape of the cross-sectional area of the inner cavity may be a pentagon, a hexagon, a heptagon, or an octagon … …, and the outer wall of the cylinder 7 may be a circle, a polygonal prism, or other regular shapes, etc. The cylinder body 7 is arranged to be the polygonal-prism inner cavity structure 8, so that the inside smoothness of the cylinder body 7 is poor, when the peeling part 4 and the grinding part 3 are driven to rotate by the rotating shaft 2 through the polygonal-prism inner cavity structure 8 of the cylinder body 7, the inner wall of the cylinder body 7 is impacted with water and the graphite ore inside, the direction of the graphite ore in the cylinder body 7 is changed, the polygonal-prism inner cavity structure 8 enables the graphite ore to be changed in direction for multiple times when rotating for a circle, so that the friction probability between the graphite ore and the peeling part 4 and the grinding part 3 is increased, when one angle of the graphite ore is not suitable for peeling or grinding, the direction of the graphite ore is changed continuously, the peeling part 4 is likely to find the direction suitable for peeling of the graphite ore, and the probability that the graphite ore is adjusted to the proper peeling angle is increased.
Preferably, the inner cavity of the cylinder 7 further includes a cylinder section 701, the cylinder section 701 is located above the polygonal column section 702, the diameter of the cylinder section 701 is larger than the maximum size of the polygonal column section 702, the discharge port 12 is located at the cylinder section 701 of the cylinder 7, most of the cylinder section 701 is graphite ore which has been stripped and ground, and the neck expansion is arranged at the cylinder section 701 to reduce the speed of the graphite ore coming out of the polygonal column section 702, so that the graphite ore which is dissociated and ground is gradually collected at the discharge port; the slower speed also enables the larger-mass graphite ore or the graphite ore which is not stripped to have enough time to sink to the multi-prism section 702 again for dissociation, but not to be thrown to the discharge port 12 along with the larger inertia and discharged together, so that most of the graphite ore is stripped, and the total stripping degree is improved.
The above-described embodiments should not be construed as limiting the scope of the invention, and any alternative modifications or alterations to the embodiments of the present invention will be apparent to those skilled in the art.
The present invention is not described in detail, but is known to those skilled in the art.
