Description

Technical Field

[0001] This invention belongs to the field of sand mill technology, specifically a vertical dual-power sand mill with recycling function. Background Technology

[0002] A sand mill is a horizontal, wet, continuous ultrafine particle disperser. Raw materials are fed into a grinding drum filled with appropriate amounts of grinding media, such as glass beads. A motor drives the dispersing blades (or pins) to rotate at high speed, imparting sufficient kinetic energy to the grinding media. This causes the media to collide with the dispersed material particles, generating shear force and achieving dispersion. The dispersed material is then separated from the grinding media and discharged through a screen, resulting in uniform and high-quality materials. This process allows for large-scale continuous production, improving both quality and cost. It is applicable to industries such as paint, ink, pharmaceuticals, food, cosmetics, and pesticides.

[0003] The main structure of a sand mill currently includes a frame, a grinding barrel, a machine spindle, and a motor; the grinding barrel is mounted on the frame and contains a rotor assembly for grinding materials.

[0004] When a sand mill grinds materials to a certain particle size, the materials need to be discharged. Currently, during the discharge process, some grinding media, zirconium beads, are often discharged together. Since zirconium beads are small in size, it is difficult to collect them, which affects the normal grinding of the sand mill.

[0005] Therefore, the present invention provides a vertical dual-power sand mill with a recycling function. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A vertical dual-power sand mill with a recycling function, comprising a sand mill body, a sand mill cylinder installed inside the sand mill body, a grinding chamber formed inside the sand mill cylinder, a main shaft rotatably mounted inside the sand mill cylinder, the end of the main shaft connected to the output end of a motor, an inner cylinder fixedly mounted on the outer surface of the main shaft, and arrayed pins fixedly mounted on the outer circumferential surface of the inner cylinder, a feed pipe installed at the bottom of the sand mill cylinder, and a separator rotatably mounted inside the sand mill cylinder. The separator has a separation shaft installed inside, and the separation shaft has a discharge through hole. During operation, the material to be ground is fed into the grinding chamber inside the grinding cylinder through the feed pipe, and the motor drives the main shaft to rotate. The main shaft drives the pins arranged in an array on its outer circumference to rotate synchronously. Under the high-speed rotation of the main shaft and multiple pins, the pins can exert strong shearing, impact and friction on the material, and gradually grind the material. At the same time, the separator is independently driven, so that the separator rotates at high speed. In this way, the grinding and separation are independently controlled, avoiding the speed coupling problem of traditional single power system.

[0008] Preferably, a mounting bracket is installed on the upper side of the side wall of the sand mill body. A separation motor is fixedly installed inside the mounting bracket. A pulley one is installed at the output end of the separation motor, and a pulley two is installed at the upper end of the separator. The pulley one and pulley two are connected by a belt. During operation, when the main shaft drives the rod pin to rotate through the inner cylinder, and it is necessary to control the rotation of the separator, the separation motor is controlled to operate, so that the output end of the separation motor drives the pulley one to rotate. The pulley one drives the pulley two to rotate through the belt, and the pulley two can then drive the separator to rotate. This design allows for easy adjustment of the separator's speed, thereby adapting to different material viscosities, ensuring efficient centrifugal sedimentation of zirconium beads in the separation zone, and reducing the risk of entering the through hole.

[0009] Preferably, a discharge bend is installed on the side wall of the mounting frame, and a filter bead is installed on the side of the mounting frame via a bracket. One end of the discharge bend extends into the discharge through-hole, and the other end extends into the filter bead. A circulating adsorption pump is installed at the bottom of the filter bead, and the adsorption end of the circulating adsorption pump extends into the interior of the filter bead. During operation, while the material is being ground normally inside the grinding cylinder, the circulating adsorption pump is simultaneously controlled to operate, so that the circulating adsorption pump generates a certain adsorption force. Moreover, the suction force generated by the circulating adsorption pump can further adsorb the material that has entered the separator and the discharge through-hole into the discharge bend, and then adsorb it into the filter bead through the discharge bend. Afterward, the material will be discharged from the bottom of the filter bead, while the zirconium beads will remain inside the filter bead, thus facilitating the subsequent recycling and processing of the zirconium beads.

[0010] Preferably, the filter bead unit has an inner tube installed inside, the top end of which extends into the interior of the discharge bend. The bottom of the inner tube has a discharge trough with a diameter smaller than that of the zirconium beads. During operation, when material is adsorbed into the filter bead unit from the discharge bend, the material and some zirconium beads enter the interior of the inner tube. The material gradually moves along the top of the inner tube to the bottom and is discharged from the interior of the discharge trough. Since the diameter of the discharge trough is smaller than that of the zirconium beads, the zirconium beads remain inside the inner tube. This achieves the separation of the material and the zirconium beads and facilitates the subsequent centralized processing of the zirconium beads.

[0011] Preferably, a solvent tank is installed on the upper side of the side wall of the sand mill body. The solvent tank is used to clean the zirconium beads inside the inner tube. A transmission unit is provided on the outside of the filter bead device. The transmission unit is used to transmit the zirconium beads collected inside the inner tube.

[0012] Preferably, the transmission unit includes a transmission tube, one end of which extends into the inner tube and the other end into the solvent tank. A sealing flap is provided at the end of the transmission tube near the inner tube, and a suction pump is installed inside the transmission tube. During operation, when a certain amount of zirconium beads are stored inside the inner tube, the rotation of the main shaft inside the grinding chamber is stopped, the suction of the circulating adsorption pump is stopped, and then the suction pump is controlled to operate, so that the suction pump generates suction force in the transmission tube and drives the sealing flap to rotate, opening the end of the transmission tube near the inner tube. Then, the zirconium beads inside the inner tube are gradually adsorbed into the solvent tank, and the zirconium beads are cleaned by the solvent inside the solvent tank. The material residue on the surface of the zirconium beads is cleaned, avoiding the decrease in grinding efficiency of the zirconium beads and the problem of material contamination during subsequent use.

[0013] Preferably, the solvent tank has a spiral pipe inside, the top of which is connected to the end of a transfer pipe. A delivery pipe is installed on the outside of the solvent tank, one end of which extends into the spiral pipe and the other end is connected to an external storage tank containing cleaning solvent. A recovery unit is located at the bottom of the spiral pipe to recover the cleaned zirconium beads. During operation, as the zirconium beads inside the inner tube are gradually adsorbed into the solvent tank, the cleaning solvent is first introduced into the spiral pipe through the delivery pipe. The zirconium beads, passing through the transfer pipe, fall from the top of the spiral pipe and gradually move along the spiral path to the recovery unit at the bottom. This achieves automatic cleaning of the zirconium beads. The spiral pipe, with cleaning solvent inside, extends the zirconium bead delivery time and improves the cleaning effect.

[0014] Preferably, the recycling unit includes a recycling frame installed at the bottom of the spiral pipe. Inside the recycling frame are three layers of vibrating screens, each with screen holes on its surface. The diameter of the screen holes decreases from top to bottom. The sidewalls of the vibrating screens are connected to the output end of the vibrating motor. During operation, when the cleaned zirconium beads fall along the spiral pipe into the recycling frame below, they first land on the surface of the uppermost vibrating screen. As the vibrating screens vibrate continuously, the diameter of the screen holes gradually decreases from top to bottom. Therefore, some severely worn zirconium beads, with their smaller diameter, will first fall along the uppermost vibrating screen to the middle vibrating screen, while smaller fragments will continue to fall along the middle vibrating screen to the lowermost vibrating screen. This process effectively separates damaged zirconium beads, preventing excessively worn zirconium beads from flowing back into the grinding chamber and affecting the normal grinding of the material. It also allows for the collection of excessively worn zirconium beads.

[0015] Preferably, all three layers of the vibrating screen are designed with an inclination. The side wall of the recycling frame is provided with three collection ports, which are located on the side wall of the vibrating screen. During operation, due to the inclination design of the vibrating screen, worn or unworn zirconium beads on the surface of each layer of the vibrating screen will slide down along its inclination surface to the collection port and be collected through the collection port. The design of the vibration spring can improve the vibration effect of the vibrating screen. At the same time, the cleaning solvent will gradually fall to the bottom of the recycling frame for easy collection and reuse.

[0016] Preferably, each layer of the vibrating screen is equipped with a vibration spring on its sidewall, and the bottom of the recycling frame is provided with a collection trough.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The vertical dual-power sand mill with recycling function described in this invention, when the main shaft drives the rod pin to rotate through the inner cylinder and when it is necessary to control the rotation of the separator, the separation motor is controlled to operate, so that the output end of the separation motor drives pulley one to rotate, pulley one drives pulley two to rotate through the belt, and pulley two can drive the separator to rotate. This design can easily adjust the speed of the separator, thereby adapting to different material viscosities, ensuring efficient centrifugal sedimentation of zirconium beads in the separation zone, and reducing the risk of entering the through hole.

[0019] 2. The vertical dual-power sand mill with recovery function described in this invention, when the zirconium beads inside the inner tube are gradually adsorbed into the solvent tank, the cleaning solvent is first introduced into the spiral pipe through the conveying pipe. The zirconium beads will fall from the top of the spiral pipe through the conveying pipe and gradually move along the spiral path of the spiral pipe to the recovery unit at its bottom, thus realizing the automatic cleaning function of zirconium beads. The spiral pipe is designed and the cleaning solvent is set inside the spiral pipe, which extends the conveying time of zirconium beads and improves the cleaning effect of zirconium beads.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 12 As shown in the figure, a vertical dual-power sand mill with recycling function according to an embodiment of the present invention includes a sand mill body 1, a sand mill cylinder 2 installed inside the sand mill body 1, a grinding chamber opened inside the sand mill cylinder 2, a main shaft 3 rotatably installed inside the sand mill cylinder 2, the end of the main shaft 3 being connected to the output end of a motor, an inner cylinder 302 fixedly installed on the outer surface of the main shaft 3, and array-shaped pins 301 fixedly installed on the outer circumferential surface of the inner cylinder 302, a feed pipe 4 installed at the bottom of the sand mill cylinder 2, a separator 201 rotatably installed inside the sand mill cylinder 2, a separation shaft 202 installed inside the separator 201, a discharge through hole 5 opened inside the separation shaft 202, and a filter bead 9 provided on the side wall of the sand mill body 1 for collecting zirconium beads;

[0036] During operation, the material to be ground is fed into the grinding chamber inside the mill cylinder 2 through the feed pipe 4, and the motor drives the main shaft 3 to rotate. The main shaft 3 drives the array of pins 301 on its outer circumference to rotate synchronously. Under the high-speed rotation of the main shaft 3 and multiple pins 301, the pins 301 can apply strong shearing, impact and friction to the material and gradually grind the material. At the same time, the separator 201 is independently driven, so that the separator 201 rotates at high speed. In this way, the grinding and separation are independently controlled, avoiding the speed coupling problem of traditional single power system.

[0037] When the separator 201 rotates at high speed, under the action of centrifugal force, the grinding media - zirconium beads - will be thrown into the grinding chamber when they come into contact with the separator 201. When the separator 201 rotates at high speed, it will drive the separation shaft 202 to rotate synchronously. Therefore, some of the smaller and lighter material solutions after grinding will be discharged through the opening in the middle of the separator 201, realizing the function of automatic material recovery. Then, the filter bead 9 can collect some of the zirconium beads sucked into the separator 201, thus facilitating the subsequent recycling and reuse of zirconium beads.

[0038] A mounting bracket 6 is installed on the upper side of the side wall of the sand mill body 1. A separation motor 601 is fixedly installed inside the mounting bracket 6. A pulley 7 is installed at the output end of the separation motor 601. A pulley 8 is installed at the upper end of the separator 201. The pulley 7 and the pulley 8 are connected by a belt.

[0039] During operation, when the main shaft 3 drives the pin 301 to rotate through the inner cylinder 302, and it is necessary to control the rotation of the separator 201, the separator motor 601 is controlled to operate, so that the output end of the separator motor 601 drives the pulley 7 to rotate. The pulley 7 drives the pulley 8 to rotate through the belt, and the pulley 8 can drive the separator 201 to rotate. This design allows for easy adjustment of the speed of the separator 201, thereby adapting to different material viscosities.

[0040] The side wall of the mounting frame 6 is equipped with a discharge bend 602. The filter bead 9 is connected to the side of the mounting frame 6 by a bracket. One end of the discharge bend 602 passes through the discharge through hole 5, and the other end passes through the filter bead 9. A circulating adsorption pump 10 is installed at the bottom of the filter bead 9. The adsorption end of the circulating adsorption pump 10 passes through the interior of the filter bead 9.

[0041] During operation, while the material is being ground normally inside the grinding cylinder 2, the circulating adsorption pump 10 is simultaneously controlled to operate, so that the circulating adsorption pump 10 generates a certain adsorption force. Moreover, the suction force generated by the circulating adsorption pump 10 can further adsorb the material that has entered the separator 201 and the discharge through hole 5 into the discharge bend 602, and then adsorb it into the filter bead 9 through the discharge bend 602. After that, the material will be discharged from the bottom of the filter bead 9, while the zirconium beads will remain inside the filter bead 9, which facilitates the subsequent recycling and processing of the zirconium beads.

[0042] The filter bead 9 has an inner tube 11 installed inside. The top end of the inner tube 11 extends into the discharge bend 602. The bottom of the inner tube 11 has a discharge groove 12, the diameter of which is smaller than the diameter of the zirconium beads. During operation, when material is adsorbed into the filter bead 9 from the discharge bend 602, the material and some zirconium beads will enter the inner tube 11. The material will gradually move along the top of the inner tube 11 to the bottom and be discharged from the discharge groove 12. Since the diameter of the discharge groove 12 is smaller than the diameter of the zirconium beads, the zirconium beads will remain inside the inner tube 11. This achieves the separation of the material and the zirconium beads and facilitates the subsequent centralized processing of the zirconium beads.

[0043] A solvent tank 13 is installed on the upper side wall of the sand mill body 1. The solvent tank 13 is used to clean the zirconium beads inside the inner tube 11. A transmission unit is provided on the outside of the filter bead 9. The transmission unit is used to transfer the zirconium beads collected inside the inner tube 11. The transmission unit includes a transmission pipe 14, one end of which extends into the inner tube 11 and the other end extends into the solvent tank 13. A sealing flap 141 is provided at the end of the transmission pipe 14 near the inner tube 11. A suction pump body 15 is installed inside the transmission pipe 14. During operation, when the inner tube 11 stores a certain amount of zirconium beads... When grinding zirconium beads in a measured quantity, first stop the rotation of the main shaft 3 inside the grinding chamber, then stop the suction of the circulating adsorption pump 10, and then control the operation of the suction pump body 15 so that the suction pump body 15 generates suction force in the transmission pipe 14 and drives the sealing flap 141 to rotate, opening the end of the transmission pipe 14 near the inner pipe 11. Then, the zirconium beads inside the inner pipe 11 will be gradually adsorbed into the solvent tank 13, and the zirconium beads can be cleaned by the solvent inside the solvent tank 13. The material residue on the surface of the zirconium beads is cleaned to avoid the decrease in grinding efficiency of the zirconium beads and the problem of material contamination during subsequent use.

[0044] It should be noted that the sealing flap valve 141 is a check valve with the function of preventing backflow. When it is not subjected to the suction force of the suction pump body 15, the sealing flap valve 141 is used to block the end of the transmission pipe 14. When it is subjected to the suction force of the suction pump body 15, the sealing flap valve 141 will rotate to a certain extent and open the end of the transmission pipe 14.

[0045] The solvent tank 13 has a spiral pipe 16 inside, the top end of the spiral pipe 16 is connected to the end of the transfer pipe 14, and a delivery pipe 17 is installed on the outside of the solvent tank 13. One end of the delivery pipe 17 passes through the spiral pipe 16 and the other end is connected to an external storage tank. The storage tank contains cleaning solvent, and a recovery unit is provided at the bottom of the spiral pipe 16. The recovery unit is used to recover the cleaned zirconium beads.

[0046] During operation, as the zirconium beads inside the inner tube 11 are gradually adsorbed into the solvent tank 13, the cleaning solvent is first introduced into the spiral pipe 16 through the delivery pipe 17. The zirconium beads, which are transported through the transfer pipe 14, fall from the top of the spiral pipe 16 and gradually move along the spiral path of the spiral pipe 16 to the recovery unit at its bottom. This achieves the automatic cleaning function of the zirconium beads. The spiral pipe 16 is designed with cleaning solvent inside, which extends the transport time of the zirconium beads and improves the cleaning effect of the zirconium beads.

[0047] The recycling unit includes a recycling frame 18, which is installed at the bottom of the spiral pipe 16. Three layers of vibrating screens 19 are installed inside the recycling frame 18. Each layer of vibrating screen 19 has screen holes 20 on its surface. The diameter of the screen holes 20 of the vibrating screen 19 decreases from top to bottom. The side wall of the vibrating screen 19 is connected to the output end of the vibrating motor.

[0048] During operation, the cleaned zirconium beads fall along the spiral pipe 16 into the lower recycling frame 18. The zirconium beads first land on the surface of the uppermost vibrating screen 19. As the vibrating screen 19 vibrates continuously, the diameter of the screen holes 20 of the three layers of vibrating screen 19 gradually decreases from top to bottom. Therefore, some of the more severely worn zirconium beads have smaller diameters and will fall along the uppermost vibrating screen 19 to the middle vibrating screen 19. Some smaller fragments will continue to fall along the middle vibrating screen 19 to the lowermost vibrating screen 19. This process can screen the damaged zirconium beads, prevent some excessively worn zirconium beads from flowing back into the grinding chamber and affecting the normal grinding of the material, and collect the excessively worn zirconium beads.

[0049] All three layers of vibrating screens 19 are designed with an inclination. The side wall of the recycling frame 18 is provided with three collection ports 21, which are located on the side wall of the vibrating screen 19. Each layer of vibrating screen 19 is equipped with a vibration spring 22 on its side wall, and the bottom of the recycling frame 18 is provided with a collection trough.

[0050] During operation, due to the inclined design of the vibrating screen 19, the worn or unworn zirconium beads on the surface of each layer of the vibrating screen 19 will slide down along its inclined surface to the collection port 21 and be collected through the collection port 21. The vibration spring 22 is designed to improve the vibration effect of the vibrating screen 19. At the same time, the cleaning solvent will gradually fall to the bottom of the recovery frame 18 for easy collection and reuse.

[0051] During operation, the material to be ground is fed into the grinding chamber inside the mill cylinder 2 through the feed pipe 4, and the motor drives the main shaft 3 to rotate. The main shaft 3 drives the array of pins 301 on its outer circumference to rotate synchronously. Under the high-speed rotation of the main shaft 3 and multiple pins 301, the pins 301 can apply strong shearing, impact and friction to the material and gradually grind the material. At the same time, the separator 201 is independently driven, so that the separator 201 rotates at high speed. In this way, the grinding and separation are independently controlled, avoiding the speed coupling problem of traditional single power system.

[0052] When the separator 201 rotates at high speed, under the action of centrifugal force, the grinding media - zirconium beads - are thrown into the interior of the grinding chamber when they come into contact with the separator 201. Some of the smaller and lighter material solutions after grinding will be discharged through the opening in the middle of the separator 201, realizing the function of automatic material recovery. When the main shaft 3 drives the rod pin 301 to rotate through the inner cylinder 302, and it is necessary to control the rotation of the separator 201, the separation motor 601 is controlled to run, so that the output end of the separation motor 601 drives the pulley 7 to rotate. The pulley 7 drives the pulley 8 to rotate through the belt. The pulley 8 can then drive the separator 201 to rotate. This design allows for easy adjustment of the speed of the separator 201, thereby adapting to different material viscosities.

[0053] While the material is being ground normally inside the mill cylinder 2, the circulating adsorption pump 10 is simultaneously operated, generating a certain adsorption force. The suction force generated by the circulating adsorption pump 10 further adsorbs the material entering the separator 201 and the discharge through-hole 5 into the discharge bend 602, and then into the filter bead 9. The material is then discharged from the bottom of the filter bead 9, while the zirconium beads remain inside the filter bead 9, facilitating the subsequent recycling of the zirconium beads. When the material is adsorbed into the filter bead 9 from the discharge bend 602, the material and some zirconium beads enter the inner tube 11. The material gradually moves along the top of the inner tube 11 to the bottom and is discharged from the discharge trough 12. Since the diameter of the discharge trough 12 is smaller than the diameter of the zirconium beads, the zirconium beads remain inside the inner tube 11. This achieves the separation of the material and the zirconium beads and facilitates the subsequent centralized processing of the zirconium beads.

[0054] When a certain amount of zirconium beads are stored inside the inner tube 11, the rotation of the main shaft 3 inside the grinding chamber is stopped first, then the suction of the circulating adsorption pump 10 is stopped. Next, the suction pump body 15 is controlled to operate, generating suction force within the transfer pipe 14 and causing the sealing flap gate 141 to rotate, opening the end of the transfer pipe 14 near the inner tube 11. The zirconium beads inside the inner tube 11 are then gradually adsorbed into the solvent tank 13, where the solvent cleans the zirconium beads, removing any material residue from their surface and preventing problems during subsequent use. The grinding efficiency of zirconium beads decreases, which can lead to material contamination. When the zirconium beads inside the inner tube 11 are gradually adsorbed into the solvent tank 13, the cleaning solvent is first introduced into the spiral pipe 16 through the conveying pipe 17. The zirconium beads through the transmission pipe 14 fall from the top of the spiral pipe 16 and gradually move along the spiral path of the spiral pipe 16 to the recovery unit at its bottom. This achieves the automatic cleaning function of zirconium beads. The spiral pipe 16 is designed and the spiral pipe 16 is equipped with cleaning solvent, which extends the conveying time of zirconium beads and improves the cleaning effect of zirconium beads.

[0055] As the cleaned zirconium beads fall along the spiral pipe 16 into the lower recycling frame 18, they first land on the surface of the uppermost vibrating screen 19. With the continuous vibration of the vibrating screen 19, the diameter of the screen holes 20 gradually decreases from top to bottom across the three layers of vibrating screens 19. Therefore, some of the more severely worn zirconium beads, with their smaller diameters, will first fall along the uppermost vibrating screen 19 to the middle vibrating screen 19, while smaller fragments will continue to fall along the middle vibrating screen 19 to the lowermost vibrating screen 19. This process effectively cleans the damaged zirconium beads. The beads are screened to prevent excessively worn zirconium beads from flowing back into the grinding chamber and affecting the normal grinding of materials. Excessively worn zirconium beads can also be collected. Since the vibrating screen 19 is designed with an inclination, worn or unworn zirconium beads on the surface of each layer of the vibrating screen 19 will slide down its inclination surface to the collection port 21 and be collected through the collection port 21. The vibration spring 22 is designed to improve the vibration effect of the vibrating screen 19. At the same time, the cleaning solvent will gradually fall to the bottom of the recovery frame 18 for easy collection and reuse.
