Description

Technical Field

[0001] The invention relates to the technical field of sand mills, and in particular to a sand mill suitable for minerals with different hardnesses and a working method. Background Art

[0002] Sand mills can be roughly divided into horizontal sand mills, basket sand mills, vertical sand mills, etc. according to their performance. They are mainly composed of a body, a grinding cylinder, a sand grinding disc (paddle), a grinding medium, a motor and a feed pump. The speed of feeding is controlled by the feed pump. Compared with grinding equipment such as ball mills, roller mills, and colloid mills, sand mills have the advantages of high production efficiency, strong continuity, low cost, and high product fineness.

[0003] A sand mill with the publication number CN116510845A comprises a base, a transmission box is installed on the base, a grinding cylinder body and a main motor are installed on one side of the transmission box, a main shaft is installed inside the grinding cylinder body, the main motor is connected to one end of the main shaft through a pulley in the transmission box, a feeding port and a discharging port are provided on the grinding cylinder body, a bead adding port connected to the inside of the grinding cylinder body for adding zirconium beads is provided on the top of one side of the grinding cylinder body, a bead discharging port connected to the inside of the grinding cylinder body for discharging zirconium beads is provided on the bottom of one side of the grinding cylinder body, a plurality of dispersion discs are evenly arranged along the axial direction of the main shaft, and a plurality of crescent-shaped separation holes are evenly distributed on each dispersion disc. By fixing a plurality of dispersion discs with special structures on the outer wall of the main shaft, on the one hand, the phenomenon of zirconium beads piling up at the discharging place during the grinding process is avoided, and on the other hand, the material is ground more fully, which greatly improves the effect of material grinding.

[0004] There are still some problems in the practical application of the above technical solution. The grinding effect of the material depends on the movement trajectory of the material inside the device, and the movement trajectory of the material in the traditional sand mill is single. When processing materials of different hardness, it is difficult to make adaptive adjustments according to needs. In addition, too much coarse particle material is added near the feed port, and the coarse particles are unevenly distributed. During grinding, it is easy to cause different grinding effects at both ends. It is generally difficult to adjust the grinding effect according to the different hardness of the material.

[0005] Therefore, it is necessary to invent a sand mill and a working method suitable for minerals of different hardness to solve the above problems. Summary of the invention

[0026] Technical effects and advantages of the present invention:

[0027] 1. The present invention arranges a driving assembly above the frame, and a pushing assembly and a processing cylinder are arranged on one side of the driving assembly. The material can be ground in the processing cylinder. During the material processing, the pushing assembly can push the material to move to increase the movement range of the material, thereby increasing the collision probability between the material and the grinding medium. At the same time, the movement amplitude of the pushing assembly can be adjusted to adapt to materials of different hardness, thereby controlling the movement trajectory of the material to adapt to the processing of materials of different hardness.

[0028] 2. The present invention provides a pushing assembly and a processing cylinder. When the material is processed in the processing cylinder, the pushing assembly and the processing cylinder can rotate under the drive of the driving assembly, and the rotation direction of the pushing assembly is opposite to that of the processing cylinder, thereby improving the effect of the material in the processing cylinder, and further increasing the collision probability between the material and the grinding medium, so as to achieve the effect of improving the grinding effect.

[0029] 3. The present invention provides a pushing assembly, which includes a movable sleeve, and fan-blade-shaped pushing plates are provided on both sides of the movable sleeve. The fan-blade-shaped setting allows the pushing plate to push the material to move in a larger range to extend the movement trajectory of the material. At the same time, the pushing plate is arranged as an inclined structure, which can realize the lateral push of the material, thereby improving the circulation effect of the material in the processing cylinder, and further increasing the collision probability of the material and the grinding medium, so as to achieve the effect of improving the grinding effect.

[0030] 4. The present invention provides an adjustment component, including a slide seat, which is arranged inside the movable frame. The position of the slide seat can be adjusted by cooperating with the adjusting screw through the threaded groove. The slide seat follows the movable frame to make circular motion around the transmission shaft. When the position of the slide seat is adjusted, the radius of the circular motion changes. At this time, the motion range of one end of the swing arm changes, and the relative motion range of the reciprocating shaft changes. The swing amplitude of the push plate is adjusted according to the material of different hardness, and then the rotation amplitude of the push plate is adjusted to improve the stirring effect on the material, thereby meeting the grinding requirements of materials of different hardness.

[0031] 5. The present invention provides a suction component, which includes a piston head. One end of the piston head is fixedly arranged at one end of a connecting shaft. The connecting shaft drives the piston head to reciprocate, so that the coarse particles added at one end close to the feed port are sucked into the corresponding movable sleeve, and then discharged to the end away from the feed port, so that the added coarse particles can be evenly distributed inside the cylinder, thereby improving the grinding effect; in particular, when grinding materials with higher hardness, due to the increase in the reciprocating motion amplitude of the connecting shaft, more coarse particles and materials with high hardness can be sucked in and discharged, so that the coarse particles and materials with high hardness are evenly distributed inside the cylinder, thereby adaptively improving the grinding effect of materials with high hardness.

[0059] The pusher assembly 3 includes a plurality of movable sleeves 301 connected end to end, and a connecting seat 302 is fixedly provided at one end of the movable sleeve 301 .

[0061] More specifically, a transmission gear 308 is fixedly provided at one end of the rotating shaft 304, and the transmission gear 308 is arranged inside the movable sleeve 301.

[0062] The processing cylinder 4 includes a cylinder body 401 and an end cover 402. The two ends of the cylinder body 401 are respectively provided with a discharge port and a feed port.

The end cover 402 is movably arranged on the outside of the fixed cover 201 through a bearing, and mutually matching bumps and grooves are arranged between the end cover 402 and the cylinder body 401, which can realize the linkage between the end cover 402 and the cylinder body 401.

[0063] The present invention also provides a working method of a sand mill suitable for minerals of different hardness, comprising the following steps:

[0064] Step 1: Equipment debugging: adjust the equipment time according to the hardness of the material to be processed, and push the material within the movement range of the device as the pushing component 3 reciprocates.

[0065] The movable frame 212 follows the transmission shaft 211 to make a circular motion, and the movable frame 212 drives the reciprocating shaft 210 to move through the swing arm 213. The reciprocating shaft 210 can drive the transmission rack 309 to reciprocate through the connecting shaft 310, and the transmission rack 309 drives the push plate 305 to move through the transmission gear 308, so that the push plate 305 swings back and forth, thereby increasing the movement range of the material to extend the movement trajectory of the material, thereby increasing the probability of collision between the material and the grinding medium, so as to achieve the effect of improving the grinding effect.

[0066] Step 2: Material feeding: clean and reset the treatment cylinder 4, and then feed the material and the grinding medium into the treatment cylinder 4 through the feed port.

[0067] Step 3: Grinding treatment: the driving assembly 2 drives the pushing assembly 3 and the processing cylinder 4 to rotate. At this time, the processing cylinder 4 and the pushing assembly 3 rotate in opposite directions, so that the material is continuously pushed and dropped in the processing cylinder 4, thereby achieving the grinding effect;

[0068] When the material is being ground, the power pulley 207 in the driving component 2 is connected to a power mechanism such as a motor through a belt to realize power input. The power pulley 207 can drive the driving bevel gear 204 to rotate, and the driving bevel gear 204 can drive the two transmission bevel gears 205 to rotate, thereby driving the two power gears 206 to rotate, and the two power gears 206 rotate in opposite directions. The two power gears 206 respectively drive the first ring gear 203 and the second ring gear 404 to rotate, thereby driving the movable cover 202 and the end cover 402 to rotate, and the movable cover 202 can drive the movable sleeve 301 to rotate through the connecting seat 302 to drive the push plate 305, and the end cover 402 can drive the cylinder 401 to rotate, so as to drive the cylinder 401.

[0069] When the movable cover 202 rotates, the connecting gear 216 inside the movable cover 202 rotates. Since a fixed gear 218 is provided on the outer side of the connecting gear 216, the connecting gear 216 rotates inside the fixed gear 218. The connecting gear 216 can drive the transmission shaft 211 to rotate through the reversing bevel gear 215 and the connecting bevel gear 214, and the transmission shaft 211 can drive the movable frame 212 to rotate. The movable frame 212 drives the reciprocating shaft 210 to move through the swing arm 213 to realize the swing drive of the push plate 305.

[0070] When the material is being ground, the push plate 305 rotates around the central axis inside the cylinder 401, which can push the material to move, so that the material is thrown up inside the cylinder 401. At the same time, the push plate 305 itself can swing, which can exert a lateral force on the material, so that the material moves along the central axis of the cylinder 401 to increase the movement range of the material, thereby increasing the probability of collision between the material and the grinding medium, so as to achieve the purpose of improving the grinding effect.

[0071] Step 4: unloading. After the material is processed, it can be discharged through the discharge port on the processing cylinder 4.

[0072] Embodiment 2

[0073] In the above embodiment, the movable frame 212 follows the transmission shaft 211 to make circular motion, and the movable frame 212 drives the reciprocating shaft 210 to move through the swing arm 213, and the reciprocating shaft 210 can drive the transmission rack 309 to reciprocate through the connecting shaft 310, and the transmission rack 309 drives the push plate 305 to move through the transmission gear 308, so that the push plate 305 swings back and forth, increasing the movement range of the material, so as to extend the movement trajectory of the material, and thus increase the collision probability between the material and the grinding medium. However, the swing amplitude of the push plate 305 cannot be adjusted, and materials of different hardness can only be ground in the same way in the same processing cylinder 4, resulting in different grinding effects of materials of different hardness. Therefore, the material grinding cannot achieve the desired effect. For this reason, the relevant components of the device are further improved.

[0074] Specifically, Fig.16 As shown, it also includes an adjustment component 6, which includes a slide 601. The slide 601 is arranged inside the movable frame 212. The middle part of the movable frame 212 is set to be hollow. A swing arm 213 is movably arranged on the outer side of the slide 601 through a pin shaft, and one end of the swing arm 213 is movably connected to one end of the reciprocating shaft 210 through the pin shaft. A thread groove 602 is penetrated through the middle part of the slide 601, and an adjusting screw 603 is penetrated through the inside of the thread groove 602. The adjusting screw 603 is set inside the movable frame 212 through a bearing. The thread groove 602 cooperates with the adjusting screw 603 to realize the adjustment of the position of the slide 601, and the slide 601 follows the movable frame 212 to make a circular motion around the transmission shaft 211. When the position of the slide 601 is adjusted, the radius of the circular motion changes. At this time, the motion range of one end of the swing arm 213 changes, and the relative motion range of the reciprocating shaft 210 changes.

[0075] More specifically, by adjusting the swing amplitude of the push plate 305, the movement trajectory of the material in the processing cylinder 4 can be adjusted, so as to adapt to the grinding process of materials with different hardness. When adjusting the movement trajectory of the push plate 305, the inspection ports on the fixed cover 201 and the movable cover 202 can be opened, and the adjusting screw 603 can be rotated. The adjusting screw 603 cooperates with the thread groove 602 to make the slide 601 slide in the movable frame 212. Since the movable frame 212 follows the transmission shaft 211 to make a circular motion, and drives the reciprocating shaft 210 through the slide 601 Movement, therefore, when adjusting the position of the slide 601 in the movable frame 212, the reciprocating range of the reciprocating shaft 210 can be adjusted, and the reciprocating shaft 210 can drive the transmission rack 309 to reciprocate through the connecting shaft 310, and the transmission rack 309 drives the push plate 305 to move through the transmission gear 308, so that the push plate 305 swings back and forth. When the movement range of the reciprocating shaft 210 is adjusted, the relative swing amplitude of the push plate 305 is adjusted, so that the movement trajectory of the material can be adjusted, and the grinding effect of the material is also improved.

[0076] Embodiment 3

[0077] In the above embodiment, the material is put into the cylinder 401 through the feed port, and the processing cylinder 4 and the pushing assembly 3 are driven by the driving assembly 2 to make circular motion and grind the material, and the motion trajectories of the processing cylinder 4 and the pushing assembly 3 are opposite. At the same time, when the pushing assembly 3 makes circular motion, the components inside the pushing plate 305 also rotate, which increases the collision probability between the material and the grinding medium. However, when feeding, there are more coarse particles at one end of the feed port, and less coarse particles at the other end, and more fine materials are ground, which eventually leads to uneven distribution of coarse particles inside the cylinder 401 and poor grinding effect. For this reason, the relevant components of the device are further improved.

[0078] Specifically, Fig.14 and Fig.15 As shown, it also includes a suction component 5, which includes a piston head 501. One end of the piston head 501 is fixedly set at one end of the connecting shaft 310, and the piston head 501 slides along the inside of the movable sleeve 301. The piston head 501 is set inside the movable sleeve 301 at the tail end, and is driven by the connecting shaft 310 to slide inside to generate suction and thrust. One end of the movable sleeve 301 is respectively fixedly provided with a first valve body 502 and a second valve body 503.

[0079] Specifically, the first valve body 502 may be a one-way valve for feeding, and the second valve body 503 may be a one-way valve for discharging. When the piston head 501 is twitched to generate suction, the coarse particles enter the movable sleeve 301 through the first valve body 502, and when the piston head 501 is pushed to generate thrust, the coarse particles are discharged through the second valve body 503. Of course, in order to realize automatic control, the first valve body 502 and the second valve body 503 may be configured as solenoid valves and electrically connected to the control system; when the piston head 501 generates suction, the first valve body 502 is opened and the second valve body 503 is closed, so that the coarse particles can be sucked into the movable sleeve 301; and when the piston head 501 generates thrust, the first valve body 502 is closed and the second valve body 503 is opened, so that the coarse particles are discharged from the movable sleeve 301.

[0080] Specifically, the first valve body 502 is fixedly arranged at one end of the rear end movable sleeve 301, the second valve body 503 is fixedly arranged at the bottom of the rear end movable sleeve 301, and a discharge pipe 504 is fixedly arranged at one end of the second valve body 503, and the discharge pipe 504 is fixed to the outer wall of the movable sleeve 301 by a buckle, and a plurality of nozzles are arranged on the discharge pipe 504 to facilitate the material to be sprayed out. Specifically, more nozzles can be arranged away from the feed end to improve the uniformity of the distribution of coarse particles in the cylinder 401, thereby improving the grinding effect.

[0081] When grinding the material, the material is put into the cylinder 401, and the driving component 2 drives the cylinder 401 and the movable sleeve 301 to rotate, and the rotation trajectories of the two are opposite. The movable sleeve 301 drives the push plate 305 to rotate to grind the material. At the same time, the driving component 2 also drives the transmission rack 309 and the connecting shaft 310 to reciprocate inside the movable sleeve 301, thereby driving the push plate 305 to rotate. The rotated push plate 305 increases the movement range of the material and the grinding medium, thereby increasing the probability of collision between the two. When the driving assembly 2 drives the transmission rack 309 and the connecting shaft 310 to reciprocate, and the connecting shaft 310 drives the piston head 501 to move toward the discharge port, at this time, the first valve body 502 is opened, and the second valve body 503 is closed, and the suction force generated by the piston head 501 in the movable sleeve 301 sucks the coarse particle material near the end of the feed port in the cylinder 401 into its interior; and when the connecting shaft 310 and the piston head 501 move away from the discharge port and toward the feed port, the first valve body 502 is closed, and the second valve body 503 is opened, and the piston head 501 pushes the sucked coarse particle material to be discharged through the second valve body 503 and the discharge pipe 504, and finally discharged through the nozzle, so as to improve the uniformity of the distribution of the coarse particle material in the cylinder 401, thereby improving the grinding effect.

[0082] Moreover, when it is necessary to grind materials with relatively large hardness, after the adjustment component 6 adjusts its position, as the movement amplitude of the reciprocating shaft 210 increases, the material sucked in and discharged by the piston head 501 also increases, so that more coarse-grained materials are evenly distributed in the cylinder 401, thereby improving the grinding effect of the coarse-grained materials and being able to adapt to the grinding of materials of different hardness. This is another important technical effect produced after the improvement of this embodiment.

[0083] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
