Description

Technical Field

[0001] The present invention relates to the technical field of raw material crushing and screening, and specifically to a crushing device for the production and processing of nano-calcium powder. Background Art

[0002] At present, there are many types of crushing devices for the production and processing of nano-calcium powder in China. During the production process of nano-calcium powder, some new crushing devices have high production efficiency, can crush calcium carbonate into smaller particle sizes at one time, reduce the technological process, and can better control the particle size distribution of nano-calcium powder, improve the uniformity and quality of products by optimizing the structure and process parameters of the crushing device, and some devices have high crushing efficiency and low energy consumption.

[0003] However, some devices have problems such as incomplete raw material crushing, rapid wear of the lining plate, and difficulty in replacement, which increase the maintenance cost, and there are also problems such as low energy utilization rate. In some production processes, due to many factors affecting the particle size and great control difficulty, the particle size distribution may be uneven.

[0004] In summary, we propose a crushing device for facilitating the production and processing of nano-calcium powder. The raw materials for the production of crushed nano-calcium powder are cut, torn, and extruded by the inward movement of the crushing sawteeth. The rotational movement of the crushing sawteeth causes the raw materials to be repeatedly impacted and sheared in the crushing chamber, ensuring that the raw materials are fully crushed into the required particle size. By adjusting the shape and spacing of the crushing sawteeth, different crushing requirements can be met, thereby achieving an efficient crushing effect, reducing the wear of the device, extending the service life of the device, and reducing energy consumption at the same time.

[0015] The crushing equipment for the production and processing of nano calcium powder proposed by the present invention can bring the following beneficial effects:

[0016] 1. A crushing device for the production and processing of nano-calcium powder. The raw materials are conveyed into the crushing chamber inside the feed hopper through a conveyor belt. The crushing sawteeth sleeved inside the first rotating shaft and the second rotating shaft move inwards to cut, tear and extrude the raw materials for the production of nano-calcium powder. The rotational movement of the crushing sawteeth causes the raw materials to be subjected to multiple impact forces and shear forces inside the crushing chamber, ensuring that the raw materials are fully crushed into the required particle size.

When the round plate at the top of the flipping rod moves upwards along the lead screw driven by the motor, it smoothly slides into the sliding plate through the notch for adjustment and positioning, making the structure have a certain flexibility. The unqualified coarse particles are poured into the crushing chamber inside the feed hopper for re-crushing to ensure that the final powder is uniform and delicate.

[0018] 3. A crushing device for the production and processing of nano-calcium powder. After being re-crushed by the crushing sawteeth and leaking out from the screen, the particles will evenly flow out through the mesh holes of the return material sieve box and finally reach the receiving box at the bottom of the opening of the base, effectively improving the crushing efficiency, reducing energy consumption, and ensuring the long-term stable operation of the equipment. Through the settings of the flipping rod, sliding plate and sliding rod, automatic screening and cyclic crushing of the particles are realized, greatly optimizing the process flow and improving the overall working efficiency.

[0035] such as Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a crushing device for the production and processing of nano calcium powder, including a base 1, a bracket 2, a feed hopper 3, and a crushing chamber 4. A bracket 2 is fixedly installed at the top end of the base 1, and a feed hopper 3 is fixedly installed in the middle of the top end of the bracket 2. The bottom end of the bracket 2 is fixedly hinged with a crushing chamber 4. The bracket 2 is used to fixedly install the feed hopper 3 and support the crushing chamber 4, playing a role of connection and support, guiding the raw materials from the feed hopper 3 into the crushing chamber 4. The feed hopper 3 is in the shape of an inverted frustum. A group of slide baffles 5 convenient for the raw materials to slide in are fixedly installed on the inner walls on both sides of the crushing chamber 4. A group of fixing plates 6 are fixedly hinged at the bottom ends of the slide baffles 5. A group of crushing saw teeth 7 are movably installed in the middle of the interior of the crushing chamber 4. The crushing saw teeth 7 are engaged with each other, and the fixing plates 6 are used to connect and stabilize the crushing saw teeth 7. A conveyor belt 8 is movably installed on one side of the bracket 2. A conveyor motor 9 is fixedly installed in the middle of one side of the conveyor belt 8. The surface of the conveyor belt 8 is rough. Roller supports are fixedly installed at the front and rear ends of the conveyor belt 8 to support the conveyor belt 8 and reduce friction and wear during operation. The conveyor motor 9 drives the conveyor belt 8 to move the materials placed on the conveyor belt 8, thereby conveying the raw materials for the production of nano calcium powder into the internal crushing chamber 4 through the feed hopper 3. And the conveyor belt 8 is inclined, which is convenient for better conveying the raw materials for crushing;

[0036] A support seat 10 is fixedly hinged in the middle of one side of the bracket 2. A second motor 11 is fixedly hinged at the top end of the support seat 10. A first rotating shaft 12 is fixedly installed at the output end of the second motor 11. The other end of the first rotating shaft 12 is fixedly connected with a driving gear 13. A second rotating shaft 14 is fixedly installed at a position adjacent to the first rotating shaft 12. The other end of the second rotating shaft 14 is fixedly connected with a driven gear 15. And the shaft rods of the first rotating shaft 12 and the second rotating shaft 14 are both movably connected with the crushing saw teeth 7. The crushing saw teeth 7 are a group. The teeth of the driving gear 13 and the driven gear 15 are meshed with each other. When the raw materials are conveyed into the crushing chamber 4 inside the feed hopper 3 through the conveyor belt 8, the second motor 11 starts, driving the driving gear 13 connected with the second motor 11 to rotate, and together driving the driven gear 15 meshed with the driving gear 13 to rotate, thereby driving the crushing saw teeth 7 sleeved inside the first rotating shaft 12 and the second rotating shaft 14 to move inward to cut, tear and extrude the raw materials for the production of nano calcium powder. The rotational movement of the crushing saw teeth 7 enables the raw materials to be subjected to multiple impact forces and shear forces in the crushing chamber 4, ensuring that the raw materials are fully crushed into the required particle size. By adjusting the shape and spacing of the crushing saw teeth 7, different crushing requirements can be met, thus achieving an efficient crushing effect, reducing the wear of the equipment, extending the service life of the equipment, and reducing energy consumption at the same time;

[0037] A wire mesh 16 is fixedly installed at the bottom end of the crushing chamber 4. The aperture of the wire mesh 16 is relatively large. The wire mesh 16 is used to screen the larger raw materials after crushing to separate raw materials of different particle sizes. During the crushing process, the raw materials are crushed into fine particles under the impact, shearing, etc. of the crushing sawteeth 7 in the crushing chamber 4. These particles are screened through the pores of the wire mesh 16. Only the particles with a particle size smaller than the aperture of the wire mesh 16 can pass through the wire mesh 16, while the larger particles are retained on the wire mesh 16 and wait for the next step of crushing. The wire mesh 16 is a wire woven mesh, which has high strength, wear resistance and corrosion resistance, and can withstand the high stress and wear generated during the crushing process. A drawplate 17 is fixedly installed at the bottom end of the wire mesh 16. The drawplate 17 is fixed and withdrawn through a mechanical device, and the operation is simple. It can quickly switch between the closed and open states. During the crushing process of the crushing sawteeth 7, it is used to block the bottom of the wire mesh 16 to prevent the uncompletely crushed raw materials from leaking out of the wire mesh 16. This can ensure that all raw materials are fully crushed in the crushing chamber 4 to reach the required particle size. After the crushing and screening are completed, the operator withdraws the drawplate 17. At this time, the fine particle powder on the wire mesh 16 leaks out through the wire mesh 16. A funnel 18 is fixedly hinged at the bottom end of the drawplate 17. The funnel 18 adopts a smooth inner wall design to reduce the adhesion and blockage of the powder and ensure the smooth discharge of the powder. After the drawplate 17 is withdrawn, the crushed powder leaks out through the wire mesh 16, slides out of the crushing chamber 4 along the inclined surface of the funnel 18, and enters the subsequent collection or processing device. The funnel 18 is used to guide the crushed powder to smoothly discharge from the crushing chamber 4;

[0038] On both sides of the top end of the base 1, support blocks 19 are fixedly installed to enhance the stability of the device and prevent component displacement or damage caused by vibration or impact. On one side of the top end of the support block 19, a lead screw 20 is fixedly connected. At the top end of the lead screw 20, a stepper motor 21 is fixedly connected. The top end of the support block 19 is movably connected with a slider 22. In the middle of the inner sides of the sliders 22, a connecting rod is fixedly connected. The sliders 22 are a group and are respectively fixedly installed on both sides of the top end of the base 1, and the sliders 22 are located at the bottom end of the lead screw 20. On the front end of one side of the bracket 2 and the column 23, a column 23 is fixedly hinged. On both sides of the lead screw 20, a turning rod 24 passes through. The turning rod 24 is connected through both sides of the lead screw 20. In the middle of the column 23, a sliding plate 25 is fixedly connected. The sliding plate 25 is flush with the height of the feed hopper 3. Both ends of the sliding plate 25 are connected. There is a notch at the bottom end of the sliding plate 25, which is convenient for the round piece at the top end of the turning rod 24 to smoothly slide into the sliding plate 25 through the notch when moving upward along the lead screw 20 for adjustment and positioning, making the structure have a certain flexibility. On the other side of the top end of the slider 22, a sliding rod 26 is fixedly installed. In the middle of both sides of the support block 19, a return material screening box 27 is movably connected. The aperture of the return material screening box 27 is relatively small and is used to screen out unqualified coarse particles to ensure that the final powder is uniform and delicate. Since the return material screening box 27 is movably connected, it can be conveniently disassembled. The middle parts of both sides of the return material screening box 27 are fixedly connected with the connecting rods in the middle parts of both sides of the slider 22. The sliding rod 26 is used to adjust and fix the position of the return material screening box 27, reducing a part of the pulling force during the process of the lead screw 20 driving the return material screening box 27 to move upward, ensuring its stability during movement and preventing displacement caused by gravity. At the same time, the design of the sliding rod 26 enables it to withstand large pulling and pressing forces, and the heights of the lead screw 20, the column 23, and the sliding rod 26 are all higher than that of the feed hopper 3. The heights of the lead screw 20, the column 23, and the sliding rod 26 are equal. At the bottom end of the base 1, a receiving box 28 is movably installed. After the raw materials in the crushing chamber 4 are crushed by the crushing teeth 7, the materials that reach the required particle size will enter the mesh holes of the return material screening box 27 through the pores of the mesh screen 16 and pour into the inside of the receiving box 28, while the larger particles will be intercepted inside the return material screening box 27 and return to the crushing chamber 4 inside the feed hopper 3 to be crushed into powder again. When the stepper motor 21 drives the lead screw 20 to move upward, the two sliders 22 and the return material screening box 27 in the middle are also driven to slide upward along the lead screw 20 and the sliding rod 26. During the sliding process, the turning rod 24 moves upward along the lead screw 20 all the time. When reaching the height of the sliding plate 25, the turning rod 24 touches the notch of the sliding plate 25 and enters the other end of the sliding plate 25 that is connected, so that the return material screening box 27 stays above the feed hopper 3. The turning rod 24 drives the return material screening box 27 to turn over, pouring the larger particles back into the crushing chamber 4 inside the feed hopper 3. After the return material screening box 27 turns over, the larger particles smoothly return to the crushing chamber 4 inside the feed hopper 3 and continue to be crushed.Ensure uniform particle size. After the particles are crushed again by the crushing serrations 7 and leak out from the screen 16, the particles will uniformly flow out through the mesh holes of the return material screen box 27 and finally reach the opening provided at the top of the base 1, effectively improving the crushing efficiency, reducing energy consumption, and ensuring the long-term stable operation of the equipment. Through the settings of the turning rod 24, the sliding connection plate 25, and the sliding rod 26, automatic screening and cyclic crushing of the particles are realized, greatly optimizing the process flow and improving the overall working efficiency. To ensure the stable turning of the return material screen box 27, larger particles can smoothly return to the crushing chamber 4, further enhancing the durability of the equipment and the convenience of operation, enabling the entire equipment to maintain stability and reliability during high-efficiency operation. Each component is interconnected. When the equipment processes raw materials with different particle sizes, it can automatically adjust and maintain high-efficiency operation, avoiding the cumbersome manual intervention, further reducing the risk of operation errors, and ensuring the continuity of the production process.

[0039] It should be noted that the control of the conveyor motor 9, the second motor 11, the lead screw 20, and the stepper motor 21 described above can be carried out through a controller and sensors in the prior art to control the motion logic, facilitating the smooth progress of the raw material crushing process.
