Description

Technical Field

[0001] The invention relates to the technical field of crushing, in particular to a crushing and grinding device for producing white corundum capable of preventing high-temperature adhesion. Background Art

[0002] White corundum is a gem-grade natural mineral with a chemical composition of aluminum oxide, the same as sapphire and ruby, but because it does not contain common coloring impurities, it presents a colorless or almost colorless appearance. The hardness of white corundum is very high, reaching the Mohs hardness level of 9 at the gem level, second only to diamond, so it enjoys a high status in the gem market. Due to its pure appearance and excellent hardness, white corundum is often used in jewelry, such as rings, necklaces, earrings, etc. It can also be used to replace diamonds as a choice for wedding rings, because it is not only relatively low in price, but also equally durable and precious. Thanks to the high hardness of white corundum, it is suitable for use as a grinding and polishing material. White corundum powder can be added to grinding pastes, abrasives and polishing agents for processing the surfaces of metals, glass, ceramics, stones and other materials, and for manufacturing grinding tools such as grinding wheels, grinding wheels and abrasives. These tools are often used for precision machining and polishing, such as in glass manufacturing, metal processing and jewelry processing.

[0003] In general, white corundum has a wide range of application potential after crushing. It can be used in many different fields and processes, taking advantage of its high hardness and wear resistance. However, the current crushing equipment and grinding equipment are used separately. Crushing equipment cannot be used for grinding, and grinding equipment cannot be used for crushing. The working efficiency of the equipment is very low and the universality is biased. Summary of the invention

[0004] The object of the present invention is to provide a crushing and grinding device for producing white corundum which can prevent high temperature adhesion, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a crushing and grinding equipment for white corundum production that prevents high-temperature adhesion, comprising an equipment bracket, on which a casing, a feed hopper and a discharge hopper are arranged, the feed hopper is arranged above the casing, the discharge hopper is arranged below the casing, and the interior of the casing is provided with three chambers from large to small from top to bottom, the three chambers are connected up and down, a main shaft is arranged through the interior of the casing, a grinding body is arranged at positions corresponding to the three chambers on the main shaft, the lower end of the main shaft is connected to a rotating unit, the upper end of the main shaft is connected to a vibrating unit, the rotating unit is installed on the equipment bracket, the rotating unit drives the main shaft to reciprocate, the vibrating unit is arranged on the feed hopper, and the vibrating unit drives the main shaft to vibrate up and down.

[0006] Furthermore, the three chambers that change from large to small are respectively a crushing chamber, a transition chamber and a grinding chamber, and grinding teeth are arranged on the inner walls of the crushing chamber, the transition chamber and the grinding chamber, and the three grinding bodies are respectively a crushing disc, a primary grinding disc and a secondary grinding disc, and the crushing disc is located in the crushing chamber, the primary grinding disc is located in the transition chamber, and the secondary grinding disc is located in the grinding chamber. The gaps between the crushing disc, the primary grinding disc and the secondary grinding disc and the grinding teeth gradually decrease, and the main shaft drives the crushing disc, the primary grinding disc and the secondary grinding disc to rotate forward and reverse while vibrating up and down. When the white corundum block is put into the chamber through the feed hopper for crushing, the extrusion force generated by the up and down vibration between the crushing body and the grinding teeth is used to crush the white corundum block, and the rotational grinding force between the crushing body and the grinding teeth is used to further grind the white corundum block. Therefore, under the joint action of the rotating unit and the vibrating unit, a composite crushing and grinding effect is achieved for the white corundum, so that the grinding equipment can crush and grind the white corundum at the same time, further enhancing the crushing and grinding effect and improving the universal performance of the equipment.

[0007] Furthermore, the crushing disc is fixedly connected to the main shaft, the primary grinding disc and the secondary grinding disc are sleeved and installed on the main shaft, the primary grinding disc and the secondary grinding disc slide along the axial direction of the main shaft, a retaining ring is arranged on the main shaft below the primary grinding disc and the secondary grinding disc, springs are arranged between the two retaining rings and the primary grinding disc and the secondary grinding disc, and a dust cover is arranged on the outer side of the spring. Since the crushing disc and the grinding teeth in the crushing cavity need to crush the white corundum, the force required by the crushing disc is the largest, so the crushing disc and the main shaft are fixedly connected, so that the force of the main shaft can be It acts directly on the crushing disc to enhance the initial crushing effect of the crushing disc on the white corundum. Because the gap between the crushing disc, the first-level grinding disc, the second-level grinding disc and the grinding teeth gradually decreases, the movement stroke of the crushing disc when it vibrates up and down is greater than the action stroke of the first-level grinding disc and the second-level grinding disc. Therefore, the first-level grinding disc and the second-level grinding disc need to use springs to achieve contact with the grinding teeth, and the springs are used to compensate for the excessive distance of the movement stroke. The first-level grinding disc and the second-level grinding disc further crush and grind the initially crushed white corundum, and the white corundum crushed by the second-level grinding disc is discharged through the discharge hopper.

[0008] Furthermore, the bottoms of the crushing disc, the primary grinding disc and the secondary grinding disc are all provided with annular screens, the apertures of the three screens decrease from top to bottom, the three screens are in contact with the inner walls of the crushing chamber, the transition chamber and the grinding chamber respectively, the crushing chamber, the transition chamber and the grinding chamber are connected to the outside of the casing and are provided with a plurality of discharge troughs, each of which is blocked by an electric control gate plate, the electric control gate plate is connected to a control system through a circuit, the outer side of each of the discharge troughs is provided with a leather cover, the screen screens the white corundum crushed at each stage to ensure that the white corundum blocks of appropriate size enter the next chamber During the crushing and grinding process, although the crushing disc, the primary grinding disc and the secondary grinding disc vibrate up and down and rotate repeatedly, the screen is intercepted between the crushed body and the inner wall of the chamber through its own flexible adjustment to avoid leakage. After a period of crushing and grinding, the control system stops feeding, and the control system controls all the electric control gates to open the discharge chute. The white corundum blocks that have not passed through the screen are discharged from the discharge chute and roll to the raw material pile through the leather cover. After the discharge, the electric control gate closes the discharge chute, and the equipment continues to feed for crushing and grinding. The white corundum blocks that have not passed through the screen are also put back into the equipment for re-crushing.

[0009] Furthermore, the rotating unit includes a spline shaft and a driven gear. A spline hole is opened inside the main shaft, and the main shaft passes through the bottom end of the discharge hopper. The spline shaft is slidably set in the spline hole, and the driven gear is set at the bottom of the spline shaft. The driven gear is rotatably installed on the equipment bracket.

[0010] Furthermore, the rotating unit also includes an incomplete gear, a first servo motor and a transmission frame, the first servo motor is installed on the equipment bracket, the incomplete gear is installed on the first servo motor, the transmission frame and the equipment bracket are slidably installed, two sections of racks are arranged opposite to each other on the inner wall of the transmission frame, the length of one section of the rack is half of the other section of the rack, the side of the transmission frame where the two sections of the rack overlap is meshed with the incomplete gear, and only one side of the transmission frame has one end of the rack meshed with the driven gear, the control system enables the first servo motor to be powered on and run, the first servo motor drives the incomplete gear to rotate, and the incomplete gear meshes with the racks on both sides of the transmission frame in turn during the rotation process, so that the transmission frame slides back and forth, the transmission frame slides back and forth and drives the driven gear to continuously rotate forward and reverse, and the driven gear drives the main shaft to continuously rotate forward and reverse through the spline shaft.

[0011] Furthermore, a cover plate is provided at the upper end of the feed hopper, and the vibration unit is provided on the cover plate. The vibration unit includes a cylinder body and a piston plate. The piston plate is slidably provided in the cylinder body, and a transfer shaft is provided at the bottom of the piston plate.

The crankshaft drives the piston plate to slide up and down in the cylinder body through the connecting rod, and the piston plate drives the adapter shaft to move up and down. The adapter shaft further drives the adapter shaft to vibrate up and down.

[0026] A cover plate 19 is provided at the upper end of the feed hopper 5, and a vibration unit is provided on the cover plate 19. The vibration unit includes a cylinder body 20 and a piston plate 21. The piston plate 21 is slidably provided in the cylinder body 20. A transfer shaft 27 is provided at the bottom of the piston plate 21. The bottom end of the transfer shaft 27 passes through the cover plate 19 and is rotatably connected to the top of the main shaft 10. A transfer block 22 is provided above the piston plate 21. The vibration unit also includes a second servo motor 25, a connecting rod 23, a crankshaft 24 and a mounting frame 26. The second servo motor 25 and the mounting frame 26 are provided above the cylinder body 20. The crankshaft 24 is connected to the second servo motor 25 and the mounting frame 26, one end of the connecting rod 23 is connected to the crankshaft 24, and the other end of the connecting rod 23 is connected to the adapter block 22. The control system drives the second servo motor 25 to be powered on and run, and the second servo motor 25 drives the crankshaft 24 to rotate. The crankshaft 24 drives the piston plate 21 to slide up and down in the cylinder body 20 through the connecting rod 23, and the piston plate 21 drives the adapter shaft 27 to move up and down. The adapter shaft 27 further drives the adapter shaft 27 to vibrate up and down. Since the main shaft 10 and the spline shaft 14 are in a sliding connection relationship, and the adapter shaft 27 and the main shaft 10 are in a rotating connection relationship, the main shaft 10 can not only rotate repeatedly, but also vibrate up and down.

[0027] The three chambers that change from large to small are respectively a crushing chamber 2, a transition chamber 3 and a grinding chamber 4. Grinding teeth are arranged on the inner walls of the crushing chamber 2, the transition chamber 3 and the grinding chamber 4. The three grinding bodies are respectively a crushing disc 7, a primary grinding disc 8 and a secondary grinding disc 9. The crushing disc 7 is located in the crushing chamber 2, the primary grinding disc 8 is located in the transition chamber 3, and the secondary grinding disc 9 is located in the grinding chamber 4. The gaps between the crushing disc 7, the primary grinding disc 8 and the secondary grinding disc 9 and the grinding teeth gradually decrease. The main shaft 10 drives the crushing disc 7, the primary grinding disc 8 and the secondary grinding disc 9 to rotate. It vibrates up and down while rotating forward and reverse. When the white corundum block is put into the chamber through the feed hopper 5 for crushing, the extrusion force generated by the up and down vibration between the grinding body and the grinding teeth is used to crush the white corundum block, and the rotational grinding force between the grinding body and the grinding teeth is used to further grind the white corundum block. Therefore, through the joint action of the rotating unit and the vibrating unit, a composite crushing and grinding effect is achieved for the white corundum, so that the grinding equipment can crush and grind the white corundum at the same time, further enhancing the crushing and grinding effect and improving the universal performance of the equipment.

[0028] The crushing disc 7 is fixedly connected to the main shaft 10, and the primary grinding disc 8 and the secondary grinding disc 9 are sleeved and installed on the main shaft 10. The primary grinding disc 8 and the secondary grinding disc 9 slide along the axial direction of the main shaft 10. A retaining ring 13 is arranged below the main shaft 10 corresponding to the primary grinding disc 8 and the secondary grinding disc 9. Springs are arranged between the two retaining rings 13 and the primary grinding disc 8 and the secondary grinding disc 9. A dust cover (not shown in the figure) is arranged on the outer side of the spring. Since the crushing disc 7 and the grinding teeth in the crushing chamber 2 need to crush the white corundum, the force required by the crushing disc 7 is the largest. Therefore, the crushing disc 7 and the main shaft 10 are fixedly connected, so that the main shaft 10 can be The force of the shaft 10 acts directly on the crushing disk 7, enhancing the initial crushing effect of the crushing disk 7 on the white corundum. Because the gaps between the crushing disk 7, the primary grinding disk 8 and the secondary grinding disk 9 and the grinding teeth gradually decrease, the movement stroke of the crushing disk 7 when vibrating up and down is greater than the action stroke of the primary grinding disk 8 and the secondary grinding disk 9. Therefore, the primary grinding disk 8 and the secondary grinding disk 9 need to use springs to achieve contact with the grinding teeth and compensate for the excessive distance of the movement stroke through the springs. The primary grinding disk 8 and the secondary grinding disk 9 further crush and grind the initially crushed white corundum, and the white corundum crushed by the secondary grinding disk 9 is discharged through the discharge hopper 6.

[0029] The bottom of the crushing disc 7, the primary grinding disc 8 and the secondary grinding disc 9 are all provided with an annular screen 11, and the apertures of the three screens 11 decrease from top to bottom. The three screens 11 are in contact with the inner walls of the crushing chamber 2, the transition chamber 3 and the grinding chamber 4 respectively. The crushing chamber 2, the transition chamber 3 and the grinding chamber 4 are connected to the outside of the casing 1 and are provided with a plurality of discharge troughs 12. Each discharge trough 12 is blocked by an electric control gate (not shown in the figure), and the electric control gate is connected to a control system through a circuit. A leather cover (not shown in the figure) is provided on the outer side of each discharge trough 12. The screen 11 screens the white corundum crushed at each level to ensure that the white corundum blocks of appropriate size enter the lower A chamber is used for crushing and grinding. Although the crushing disc 7, the primary grinding disc 8 and the secondary grinding disc 9 vibrate up and down and rotate repeatedly, the screen 11 is intercepted between the ground body and the inner wall of the chamber through its own flexible adjustment to avoid leakage. After a period of crushing and grinding, the control system stops feeding, and the control system controls all the electric control gates to open the discharge chute 12. The white corundum blocks that have not passed through the screen 11 are discharged from the discharge chute 12 and roll down to the raw material stacking place through the leather cover. After the discharge is completed, the electric control gate closes the discharge chute 12, and the equipment continues to feed for crushing and grinding. The white corundum blocks that have not passed through the screen 11 are also re-fed into the equipment for re-crushing.

[0030] Several one-way air valves (not shown in the figure) are provided on the piston plate 21 and the corresponding cover plate 19 below the piston plate 21. When the piston plate 21 moves upward, the one-way air valve on the cover plate 19 is closed, and the one-way air valve on the piston plate 21 is opened, and air enters the cylinder body 20. When the piston plate 21 moves downward, the one-way air valve on the cover plate 19 is opened, and the one-way air valve on the piston plate 21 is closed, and air is blown from the cylinder body 20 into the feed hopper 5 and blown downward along the movement direction of the white corundum block. This can not only prevent dust from overflowing from the feed hopper 5, but also reduce the instantaneous high temperature generated by the friction between the ground body and the white corundum block through the airflow, prevent the white corundum from sticking to the ground body, and play a dual role of dust prevention and cooling.

[0031] The working principle of the present invention is as follows: the control system enables the first servo motor 17 to be powered on and run, and the first servo motor 17 drives the incomplete gear 16 to rotate. During the rotation process, the incomplete gear 16 sequentially meshes with the racks on both sides of the transmission frame 18, so that the transmission frame 18 slides back and forth, and the transmission frame 18 slides back and forth and drives the driven gear 15 to continuously rotate forward and reverse, and the driven gear 15 drives the main shaft 10 to continuously rotate forward and reverse through the spline shaft 14.

[0032] The control system drives the second servo motor 25 to operate, and the second servo motor 25 drives the crankshaft 24 to rotate. The crankshaft 24 drives the piston plate 21 to slide up and down in the cylinder body 20 through the connecting rod 23. The piston plate 21 drives the adapter shaft 27 to move up and down, and the adapter shaft 27 further drives the adapter shaft 27 to vibrate up and down. Since the main shaft 10 and the spline shaft 14 are in a sliding connection relationship, and the adapter shaft 27 and the main shaft 10 are in a rotating connection relationship, the main shaft 10 can not only rotate repeatedly, but also vibrate up and down, and the main shaft 10 drives the crushing disk 7, the primary grinding disk 8 and the secondary grinding disk 9. The grinding disc 9 rotates forward and reverse while vibrating up and down. When the white corundum block is put into the chamber through the feed hopper 5 for crushing, the extrusion force generated by the up and down vibration between the grinding body and the grinding teeth is used to crush the white corundum block, and the rotational grinding force between the grinding body and the grinding teeth is used to further grind the white corundum block. Therefore, through the joint action of the rotating unit and the vibrating unit, a composite crushing and grinding effect is achieved for the white corundum, so that the grinding equipment can crush and grind the white corundum at the same time, further enhancing the crushing and grinding effect and improving the universal performance of the equipment.

[0033] Since the crushing disk 7 and the grinding teeth in the crushing chamber 2 need to crush the white corundum, the force required by the crushing disk 7 is the greatest. Therefore, the crushing disk 7 and the main shaft 10 are fixedly connected, so that the force of the main shaft 10 can directly act on the crushing disk 7, thereby enhancing the initial crushing effect of the crushing disk 7 on the white corundum. Because the gaps between the crushing disk 7, the primary grinding disk 8 and the secondary grinding disk 9 and the grinding teeth gradually decrease, the movement stroke of the crushing disk 7 when vibrating up and down is greater than the action stroke of the primary grinding disk 8 and the secondary grinding disk 9. Therefore, the primary grinding disk 8 and the secondary grinding disk 9 need to use springs to achieve contact with the grinding teeth, and use the springs to compensate for the excessive distance of the movement stroke. The primary grinding disk 8 and the secondary grinding disk 9 further crush and grind the initially crushed white corundum, and the white corundum ground by the secondary grinding disk 9 is discharged through the discharge hopper 6.

[0034] The screen 11 screens the crushed white corundum at each level to ensure that the white corundum blocks of appropriate size enter the next chamber for crushing and grinding. Although the crushing disk 7, the first-level grinding disk 8 and the second-level grinding disk 9 vibrate up and down and rotate repeatedly, the screen 11 intercepts the crushed body and the inner wall of the chamber through its own flexible adjustment to avoid leakage. After a period of crushing and grinding, the control system stops feeding, and the control system controls all the electric control gates to open the discharge chute 12. The white corundum blocks that have not passed through the screen 11 are discharged from the discharge chute 12 and roll down to the raw material stack through the leather cover. After the discharge is completed, the electric control gate closes the discharge chute 12, and the equipment continues to feed for crushing and grinding. The white corundum blocks that have not passed through the screen 11 are also re-fed into the equipment for re-crushing.

[0035] During the upward movement of the piston plate 21, the one-way air valve on the cover plate 19 is closed, and the one-way air valve on the piston plate 21 is opened, and air enters the cylinder body 20. When the piston plate 21 moves downward, the one-way air valve on the cover plate 19 is opened, and the one-way air valve on the piston plate 21 is closed, and air is blown from the cylinder body 20 into the feed hopper 5, and blown downward along the movement direction of the white corundum stone. This can not only prevent dust from overflowing from the feed hopper 5, but also reduce the instantaneous high temperature generated by the friction between the crushed body and the white corundum stone through the airflow, prevent the white corundum from sticking to the crushed body, and play a dual role of dust prevention and cooling.
