More specifically, the inner side of the adjusting blade 203 is provided with a movable seat 204, both sides of the movable seat 204 are movably provided with a connecting arm 205 through a pin shaft, one end of the connecting arm 205 is movably arranged on the inner side wall of the adjusting blade 203 through a pin shaft, and the middle part of the movable seat 204 is fixedly provided with a movable rod 206.
And, the middle part of movable rod 206 cup joints and is provided with movable sleeve 207, and one side of movable sleeve 207 is fixed and is provided with connecting frame 208, and connecting frame 208 is fixed to be set up in the inside wall of fixed blade 201, and movable sleeve 207 plays the spacing to adjusting blade 203 through movable rod 206, movable seat 204 and linking arm 205 to guarantee the pentagonal structure of blade assembly 2 stability when the adjustment.
Moreover, one end of the movable rod 206 is fixedly disposed at one end of the connection seat 209 having the annular structure, and the inner side of the connection seat 209 is fixedly disposed at one end of the end flange 101.
When the gap between two adjacent blade assemblies 2 is adjusted, the bottom flange 102 moves and is far away from the end flange 101, the bottom flange 102 synchronously drives the fixed blades 201 to be far away from the end flange 101, and the end flange 101 and the movable rod 206 fixedly connected with the end flange are kept motionless, so that the adjusting blades 203 can be close to each other and the movable blades 202 can be close to each other under the action of the connecting arms 205, further the pentagonal structure of the blade assemblies 2 is contracted, and finally the gap between two adjacent blade assemblies 2 is enlarged.

Specifically, sleeve 302 is fixedly arranged at one end of connecting plate 301, sleeve 302 is provided with a permanent magnet, fixed column 303 is arranged in sleeve 302 in a sliding manner, a limiting block is arranged on fixed column 303, a limiting groove is arranged in sleeve 302, and through the mutual matching of the limiting block and the limiting groove, the fixed column 303 can drive sleeve 302 to synchronously rotate, and sleeve 302 can also axially slide relative to fixed column 303. One end of the fixed column 303 is fixedly arranged on the inner side of the transmission seat 104, an annular electromagnetic part 304 is fixedly arranged on the inner side of the transmission seat 104, and a telescopic spring 305 is fixedly arranged between the electromagnetic part 304 and the sleeve 302.
When the distance between the bottom flange 102 and the end flange 101 needs to be adjusted, the electromagnetic part 304 is controlled to be electrified, magnetic repulsion force is generated on the sleeve 302, the sleeve 302 is pushed to be far away, the telescopic spring 305 is stretched, and at the moment, the sleeve 302 can drive the bottom flange 102 to be far away from the end flange 101 through the connecting plate 301, so that the gap between two adjacent blade assemblies 2 is enlarged. By controlling the electromagnetic part 304 to be powered off and the telescopic spring 305 to restore the elastic deformation, the sleeve 302 is pulled to return to the initial position, or by changing the current of the electromagnetic part 304, the electromagnetic part 304 generates magnetic attraction force to the sleeve 302, the telescopic spring 305 is compressed, the sleeve 302 is close to the electromagnetic part 304, the bottom flange 102 can be driven to be close to the end flange 101, and then the gap between two adjacent blade assemblies 2 is reduced. Thus, the electromagnetic part 304, the sleeve 302, the telescopic spring 305 and the like are mutually matched, so that the adjustment of the gap size of two adjacent blade assemblies 2 is realized, and the corresponding functions of the classification wheel can be realized.
The invention also provides a sand mill with the classifying wheel, which comprises a cylinder body 5, a top cover 6 and a driving motor 7, wherein the cylinder body 5, the top cover 6 and the driving motor 7 are sequentially arranged from left to right, the supporting component 1, the blade component 2 and the driving component 3 are all arranged in the cylinder body 5, and a supporting seat is fixedly arranged at the lower end of the cylinder body 5 to play a role in supporting equipment. A rotating shaft is arranged in the cylinder body 5, and a plurality of grinding sheets are arranged on the rotating shaft.
To sum up, when the device is used, the material to be processed is put into the cylinder 5, the cylinder 5 grinds the material through the grinding sheet in the cylinder, and the ground material moves forward under the pushing of the follow-up feeding pressure in the grinding process and enters the classifying wheel. Under the action of centrifugal force generated by rotation of the classifying wheel, coarse particle materials are discharged from gaps of adjacent blade assemblies 2 of the classifying wheel and flow back to the grinding sheet for secondary or multiple grinding. And the materials with qualified granularity pass through the classifying wheel and move to the discharge end to be discharged from the discharge pipe, so that the grinding treatment and the classified discharge of the materials are realized.
In the actual grinding process of minerals, due to the change of the hardness characteristics of the minerals, when grinding the minerals with large hardness, more coarse particles need to be ground for two or more times, and the reflux distance of the coarse particles is increased, so that the reflux coarse particles can be contacted with more grinding sheets and ground for two or more times; in grinding minerals with low hardness, it is necessary to reduce the secondary or multiple grinding of minerals and reduce the distance of coarse particles flowing back to be ground as soon as possible and discharged in order to improve grinding efficiency. The following operations were performed in view of the hardness characteristics of the above-mentioned ground minerals.
When the hardness of the ground mineral is large, it is necessary to increase the amount of coarse particles discharged from the classifying wheel and increase the return distance of the coarse particles to be brought into contact with more grinding sheets. At this time, by controlling the electromagnetic portion 304 to be electrified and generating magnetic repulsive force to the sleeve 302 and pushing the sleeve 302 to be far away, at this time, the sleeve 302 can drive the bottom flange 102 to be far away from the end flange 101 through the connecting plate 301, under the action of the connecting arm 205, the adjusting blades 203 can be close to each other and the movable blades 202 can be close to each other, further the pentagonal structure of the blade assembly 2 is contracted, finally the gap between two adjacent blade assemblies 2 is enlarged, and coarse particles which can be discharged are increased under the action of centrifugal force generated by rotation of the classifying wheel. And at this time, the bottom flange 102 is far away from the end flange 101, and the bottom flange 102 drives the fixed blade 201, the movable blade 202 and the adjusting blade 203 above the bottom flange to be closer to the grinding sheets, so that coarse particles discharged in a grading manner can be contacted with more grinding sheets after flowing back and are subjected to secondary grinding, and the effect of secondary or multiple grinding of the coarse particles with high hardness is improved.
When the hardness of the ground minerals is small, it is necessary to reduce the discharge amount of the classifying wheel and reduce the return distance of coarse particles, so that the material is discharged more quickly. At this time, by controlling the electromagnetic portion 304 to be powered off, the extension spring 305 resumes the elastic deformation, the sleeve 302 is pulled to return to the initial position, or by changing the current of the electromagnetic portion 304, the electromagnetic portion 304 generates magnetic attraction to the sleeve 302, the extension spring 305 is compressed, the sleeve 302 is close to the electromagnetic portion 304, and then the bottom flange 102 is driven to be close to the end flange 101, under the action of the connecting arm 205, the adjusting blades 203 can be far away from each other and the movable blades 202 can be far away from each other, the pentagonal structure of the blade assemblies 2 is further enabled to be opened, the gap between two adjacent blade assemblies 2 is finally enabled to be reduced, even the gap is closed, at this time, less material is discharged through the centrifugal force of the classifying wheel, even no material is guaranteed, and the material with small hardness can rapidly pass through the classifying wheel and be discharged through the discharge pipe. Meanwhile, because the bottom flange 102 is close to the end flange 101 at this time, the bottom flange 102 drives the fixed blade 201, the movable blade 202 and the adjusting blade 203 above the bottom flange to be far away from the grinding sheet, and coarse particles discharged in a grading manner flow back, so that the opportunity of contacting the grinding sheet is reduced, and even coarse particles with no flow back are avoided, so that materials with small hardness can be ensured to rapidly pass through the grading wheel and be discharged from the discharge pipe after being ground, and the grinding efficiency of subsequent materials is ensured.
To sum up, this device can adjust the clearance of two adjacent blade assemblies 2 and the position of classification wheel in barrel 5 according to the hardness characteristic of grinding material in the grinding process, and then control the quantity of backward flow coarse grain and the backward flow distance of coarse grain, and then adjust grinding effect and grinding efficiency, strong adaptability, the effect is showing.
Example two
In the above embodiment, during the process of classifying the materials in the classifying wheel (for example, the line a of the materials in fig. 11), the materials conforming to the standard are discharged from the discharge pipe (for example, the line B of the materials in fig. 11), the materials not conforming to the standard are discharged from the gap of the classifying wheel and flow back into the cylinder 5 for secondary grinding (for example, the line C of the materials in fig. 11), but the materials not conforming to the standard flow back along the inner wall of the cylinder 5, can only advance by pushing the following materials, and new materials with a certain pressure can be continuously fed in the whole grinding process, and the back flow of the coarse particles is reacted, so that the back flow distance of the coarse particles is limited, which leads to the back flow of the coarse particles, the fewer the number of grinding sheets contacting the classifying wheel is, the effect that the back flow coarse particles are ground for the second time or more is worse, thus being unfavorable for the secondary grinding effect of the back flow coarse particles. Therefore, the related parts of the device are further improved, so that the reflux distance of the reflowed coarse-grain materials in the cylinder 5 is increased and the reflowed coarse-grain materials are contacted with a plurality of grinding sheets as much as possible, and the grinding effect of the large-grain materials during reflow is further improved.
Specifically, as shown in fig. 1, 4, 5 and 12, the pushing device further comprises a pushing component 4, the pushing component 4 comprises a plurality of supporting blocks 401, the supporting blocks 401 are fixedly arranged at one ends of pin shafts at the connecting positions of the two adjusting blades 203, and the two ends of the supporting blocks 401 cannot be affected by the arrangement of the supporting blocks 401. The inside of each supporting block 401 is provided with a connecting shaft 402 in a penetrating way, and the connecting shaft 402 is limited in the supporting block 401 and can only rotate but can not axially move. The one end of every connecting axle 402 is all fixed and is provided with the movable gear 403, and the movable rod 206 is close to movable gear 403 department all fixed and is provided with the pinion rack, and the pinion rack all meshes with corresponding movable gear 403, and the other end of every connecting axle 402 is all fixed and is provided with connecting block 404, and the other end of connecting block 404 is all fixed and is provided with closing plate 405, and connecting block 404 is the distortion shape, and connecting block 404 and closing plate 405 constitute the flabellum shape.
It should be noted that, by rotating the connecting shaft 402, the connecting shaft 402 can drive the connecting block 404 and the sealing plate 405 to rotate, when the connecting shaft 402 rotates forward, the angle between the connecting block 404 and the sealing plate 405 changes, and two adjacent connecting blocks 404 and the sealing plate 405 are far away from each other, as shown in fig. 12 (a), and at this time, when the connecting blocks 404 and the sealing plate 405 rotate along with the classifying wheel, a larger thrust can be generated; when the connecting shaft 402 rotates reversely, the angle between the connecting block 404 and the sealing plate 405 changes, and the adjacent two connecting blocks 404 and the sealing plate 405 approach each other, as shown in fig. 12 (b), and the thrust generated when the connecting blocks 404 and the sealing plate 405 follow the rotation of the classifying wheel is small.
Specifically, when grinding a material having a high hardness, it is necessary to increase the amount of coarse particles discharged from the classifier and increase the return distance of the coarse particles to bring the coarse particles into contact with more grinding sheets. As described in the above embodiment, the clearance between two adjacent blade assemblies 2 can be made large, and the coarse particles discharged are increased by the centrifugal force generated by the rotation of the classifying wheel. And at this time, the bottom flange 102 is far away from the end flange 101, the bottom flange 102 drives the fixed blade 201, the movable blade 202 and the adjusting blade 203 above the bottom flange to be far away from the end flange 101, and because the toothed plate on the movable rod 206 is fixed, the pin shaft at the joint of the adjusting blade 203 drives the connecting shaft 402 to move through the supporting block 401, the connecting shaft 402 drives the movable gear 403 to move on the toothed plate in a meshed manner, so that the connecting shaft 402 rotates positively, the connecting shaft 402 can drive the connecting block 404 and the sealing plate 405 to rotate positively, and the angle of the fan blade shape formed by the connecting block 404 and the sealing plate 405 can be adjusted, as shown in fig. 12 (a), when the connecting block 404 and the sealing plate 405 follow the rotation of the classifying wheel, larger thrust can be generated, coarse particles separated from the classifying wheel can be pushed, the coarse particles can flow to a longer distance along the cylinder 5, the reflowed coarse particles can be contacted with more grinding sheets, and the secondary or multiple grinding effects of the reflowed coarse particles can be improved.
Correspondingly, when grinding materials with low hardness, it is necessary to reduce the amount of coarse particles discharged from the classifying wheel and reduce the return distance of the coarse particles, so that the coarse particles are less in contact with the grinding plate and pass through the classifying wheel as soon as possible and are discharged from the discharge pipe. As described in the above embodiment, the clearance between two adjacent vane assemblies 2 can be made small, and the coarse particles discharged can be reduced by the centrifugal force generated by the classifying wheel rotation. And at this time, the bottom flange 102 is close to the end flange 101, the bottom flange 102 drives the fixed blade 201, the movable blade 202 and the adjusting blade 203 above the bottom flange to be close to the end flange 101, because the toothed plate on the movable rod 206 is fixed, the pin shaft at the joint of the adjusting blade 203 drives the connecting shaft 402 to move through the supporting block 401, the connecting shaft 402 drives the moving gear 403 to move on the toothed plate in a meshed manner, so that the connecting shaft 402 reversely rotates, and then the connecting block 404 and the sealing plate 405 can be driven to rotate, namely, the angle of the fan blade shape formed by the connecting block 404 and the sealing plate 405 can be adjusted, as shown in fig. 12 (b), when the connecting block 404 and the sealing plate 405 rotate along with the grading wheel, only small thrust is generated, the reflux distance of coarse particles is reduced, the contact between the coarse particles which are refluxed is reduced as much as possible and the grinding piece is discharged from the discharging pipe through the grading wheel as soon as possible, and the grinding efficiency is ensured.
It should be noted that, the connection block 404 and the sealing plate 405 are both disposed on the outer periphery of the classifying wheel and are close to the inner wall of the cylinder 5, and the thrust generated by the rotation of the connection block and the sealing plate acts on the coarse particles flowing back, so that the coarse particles flow back along the inner wall of the cylinder 5, and the generated thrust does not affect the movement of the grinding material from the feeding end to the discharging end in the cylinder 5.
Therefore, according to the requirements of the material grinding hardness characteristics, the angle of the fan blade shape can be formed by adjusting the connecting block 404 and the sealing plate 405, so that the reflux distance of the reflux coarse particles separated by the classifying wheel can be controlled in a targeted manner, the effect that the reflux coarse particles are ground for two or more times can be ensured, and the grinding efficiency can be ensured.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
