Description

Technical Field

[0001] This utility model belongs to the technical field of bead mills, specifically a horizontal bead mill. Background Technology

[0002] A horizontal bead mill is a continuously producing grinding and dispersing machine with a horizontal cylinder, used for grinding and dispersing solid or liquid suspensions. Its dispersion principle is as follows: the main motor drives the dispersion shaft to move at high speed through a V-belt, and the disperser on the dispersion shaft drives the grinding media to move, generating friction and shear force to grind and disperse the material.

[0003] In existing technology, during the grinding process of a ball mill, some grinding media often become damaged or incomplete due to impact. The media used in each grinding operation needs to be recycled for reuse. To ensure the grinding effect in the next operation, the staff usually need to screen the damaged or incomplete grinding media before the next grinding to ensure that the particle size of the grinding media entering the ball mill is uniform. However, the manual screening process is cumbersome, time-consuming, labor-intensive, and inefficient.

[0004] Therefore, this utility model provides a horizontal bead mill. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that in the past, when medical staff changed dressings on patients' wounds, they would typically use tweezers to pick up gauze or medical cotton to wipe the wound. During this process, because the tweezers themselves have a certain degree of elasticity, it is necessary to press the tweezers firmly with one's fingers to prevent the gauze or medical cotton from loosening, which can easily lead to finger pain for medical staff after a long time, this utility model proposes a horizontal bead mill.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A horizontal ball mill of this utility model includes a machine body, on which a ball mill cylinder is fixedly installed. A screening box is fixedly connected to the top of the ball mill cylinder. The top of the screening box is provided with a feed inlet. The bottom of the inner cavity of the screening box is funnel-shaped and communicates with the inner cavity of the ball mill cylinder. Multiple mounting plates are fixedly connected to the inner cavity of the screening box. A filter plate is provided above the mounting plate. Through holes are evenly opened on the filter plate. A rotating shaft is provided below the filter plate. The rotating shaft is rotatably connected to the inner cavity of the screening box. A cam is fixedly connected to the rotating shaft. The cam is adapted to the filter plate. Elastic support components are provided on both sides of the bottom of the filter plate. A drive component is provided on the outside of the screening box.

[0007] Preferably, the elastic support assembly includes a fixed sleeve, a top support rod, and a spring. Fixed sleeves are provided on both sides below the filter plate. The two fixed sleeves are respectively fixed to the inner wall of the mounting plate and the screen box. A top support rod is slidably connected in the inner cavity of the fixed sleeve. A spring is fixed between the top support rod and the inner cavity of the fixed sleeve. The end of the top support rod away from the spring extends to the top of the fixed sleeve and is fixed to the bottom of the filter plate.

[0008] Preferably, the drive assembly includes an L-shaped plate and a motor. An L-shaped plate is fixedly connected to the outer wall of the screening box, and a motor is fixedly installed on the L-shaped plate. One end of each of the two rotating shafts extends to the outside of the screening box and is fixedly connected to a synchronous pulley. The two synchronous pulleys are driven by a synchronous belt. The output end of the motor is fixedly connected to one of the rotating shafts.

[0009] Preferably, the top of the filter plate is wavy, the through hole is located in the recess at the top of the filter plate, the filter plate is inclined, and both sides of the filter plate are in contact with the inner wall of the screening box and the mounting plate. The mounting plate is U-shaped, and the middle part of the mounting plate is inclined. A weir plate is provided on the side of the mounting plate near the lowest point of the filter plate, and an inclined surface is provided on the top of the side of the mounting plate away from the weir plate. Multiple discharge pipes are fixedly connected to the screening box. The discharge pipes are located on the inclined surface of the mounting plate and are interconnected. A discharge pipe is fixedly connected to the outer end of the lowest discharge pipe.

[0010] Preferably, an electromagnet is fixedly installed at the bottom of the inner cavity of the mounting plate, the bottom end of the weir plate is slidably connected to the inner cavity of the mounting plate, a permanent magnet is embedded at the bottom end of the weir plate, and a spring is fixedly connected between the permanent magnet and the electromagnet.

[0011] Preferably, each of the mounting plates is provided with a second rotating shaft between the side of the mounting plate near the weir plate and the inner wall of the screening box. The second rotating shaft is rotatably connected to the inner wall of the screening box. A rotating roller is fixedly connected to the second rotating shaft. The rotating roller is uniformly provided with protrusions. One end of the second rotating shaft extends to the outside of the screening box and is fixedly connected to a synchronous pulley. The synchronous pulleys on the first rotating shaft and the second rotating shaft are both driven by a synchronous belt.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The horizontal ball mill of this utility model drives the rotating shaft of the drive component to rotate the cam, and with the help of the elastic support component, the filter plate vibrates up and down. As the grinding media rolls on the filter plate, the broken and defective grinding media falls from the through hole to the mounting plate, thereby removing the broken and defective grinding media and ensuring that the particle size of the grinding media entering the ball mill is uniform.

[0014] 2. The horizontal bead mill of this utility model increases the filtration time by designing the top of the filter plate as wavy, and further increases the residence time of the grinding medium on the filter plate by setting a weir plate on the mounting plate, thereby improving the filtration effect.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6As shown, the horizontal bead mill of this utility model includes a machine body 1, on which a grinding cylinder 2 is fixedly installed. A sieve box 3 is fixedly connected to the top of the grinding cylinder 2. The top of the sieve box 3 is provided with a feed inlet 4. The bottom of the inner cavity of the sieve box 3 is funnel-shaped and communicates with the inner cavity of the grinding cylinder 2. Multiple mounting plates 5 are fixedly connected to the inner cavity of the sieve box 3. A filter plate 6 is provided above the mounting plates 5. Through holes 7 are evenly opened on the filter plate 6. A rotating shaft 10 is provided below the filter plate 6. The rotating shaft 10 is rotatably connected to the inner cavity of the sieve box 3. A cam 11 is fixedly connected to the rotating shaft 10. The cam 11 is adapted to the filter plate 6. Elastic support components are provided on both sides of the bottom of the filter plate 6. A drive component is provided on the outside of the sieve box 3. During operation, the operator puts the grinding media into the sieve box 3 through the feed inlet 4. The grinding media enters and rolls downwards along the uppermost filter plate 6. After the first round of screening, the grinding media enters the channel formed by the mounting plate 5 and the inner wall of the sieve box 3. Then, the grinding media falls onto the next layer of filter plate 6 and continues to roll. This process is repeated until the grinding media enters the ball mill cylinder 2 after multiple rounds of screening, completing the subsequent grinding operation. The drive assembly drives the rotating shaft 10 to rotate the cam 11. With the help of the elastic support assembly, the filter plate 6 vibrates up and down. As the grinding media rolls on the filter plate 6, broken and defective grinding media fall from the through hole 7 onto the mounting plate 5, thus removing broken and defective grinding media. This ensures that the particle size of the grinding media entering the ball mill cylinder 2 is uniform, avoiding the process of manually screening and removing defective grinding media, reducing the workload of the workers, and improving the grinding efficiency.

[0025] The elastic support assembly includes a fixed sleeve 12, a top support rod 13, and a spring 14. Fixed sleeves 12 are provided on both sides below the filter plate 6. The two fixed sleeves 12 are respectively fixed to the inner walls of the mounting plate 5 and the screening box 3. A top support rod 13 is slidably connected within the inner cavity of the fixed sleeve 12. A spring 14 is fixed between the top support rod 13 and the inner cavity of the fixed sleeve 12. The end of the top support rod 13 away from the spring 14 extends above the fixed sleeve 12 and is connected to the filter plate 6. The bottom is fixed; during operation, when the cam 11 rotates upward with the rotating shaft 10 to press the filter plate 6, the filter plate 6 drives the top support rod 13 to slide upward and compress the spring 14. When the cam 11 moves away from the filter plate 6, the filter plate 6 quickly returns to its original position downward under the elastic force of the spring 14 until the cam 11 presses the filter plate 6 again. This process is repeated, which realizes the up-and-down reciprocating vibration of the filter plate 6. This not only avoids the clogging of the grinding media and causes the grinding media to roll downward, but also removes broken and defective grinding media.

[0026] The drive assembly includes an L-shaped plate 8 and a motor 9. The L-shaped plate 8 is fixedly attached to the outer wall of the screening box 3, and the motor 9 is fixedly installed on the L-shaped plate 8. One end of each of the two rotating shafts 10 extends to the outside of the screening box 3 and is fixedly attached to a synchronous pulley 18. The two synchronous pulleys 18 are driven by a synchronous belt 19. The output end of the motor 9 is fixedly connected to one of the rotating shafts 10. During operation, through the cooperation of the synchronous pulley 18 and the synchronous belt 19, when the motor 9 drives one of the rotating shafts 10 to rotate, the other rotating shafts 10 rotate accordingly, thereby causing the cam 11 in the screening box 3 to rotate synchronously and drive the filter plate 6 to vibrate up and down.

[0027] The top of the filter plate 6 is wavy, and the through hole 7 is located in the recess at the top of the filter plate 6. The filter plate 6 is inclined, and both sides of the filter plate 6 are in contact with the inner wall of the screening box 3 and the mounting plate 5. The mounting plate 5 is U-shaped, and the middle part of the mounting plate 5 is inclined. A weir plate 15 is provided on the side of the mounting plate 5 near the lowest point of the filter plate 6, and a slope is provided on the top of the side of the mounting plate 5 away from the weir plate 15. Multiple discharge pipes 20 are fixedly connected to the screening box 3. The discharge pipes 20 are located on the slope side of the mounting plate 5. The two discharge pipes 20 are interconnected, and the outer end of the discharge pipe 20 at the bottom is fixed to the discharge pipe 21. During operation, by designing the top of the filter plate 6 as a wave shape, the filtration time can be increased when the grinding medium rolls on the filter plate 6. By setting the weir plate 15 on the mounting plate 5, the residence time of the grinding medium on the filter plate 6 is further increased, and the filtration effect is improved. The broken grinding medium that falls from the through hole 7 onto the mounting plate 5 is discharged from the discharge pipe 20 and finally flows into the discharge pipe 21 and is discharged from the discharge pipe 21.

[0028] An electromagnet 22 is fixedly installed at the bottom of the inner cavity of the mounting plate 5. The bottom end of the weir plate 15 is slidably connected to the inner cavity of the mounting plate 5. A permanent magnet 23 is embedded at the bottom end of the weir plate 15. A spring 24 is fixedly connected between the permanent magnet 23 and the electromagnet 22. During operation, when the grinding is finished and the residual grinding media in the screening box 3 needs to be removed, the electromagnet 22 is energized, so that the permanent magnet 23 drives the weir plate 15 to slide downward under the magnetic attraction and compresses the spring 24. The top of the weir plate 15 is in contact with the top of the mounting plate 5 until the grinding media is completely discharged. Then the electromagnet 22 is de-energized, and the weir plate 15 slides upward and resets under the elastic force of the spring, which is convenient for the next screening of the grinding media.

[0029] Each mounting plate 5 has a rotating shaft 16 between its side near the weir plate 15 and the inner wall of the screening box 3. The rotating shaft 16 is rotatably connected to the inner wall of the screening box 3. A rotating roller 17 is fixedly connected to the rotating shaft 16. The rotating roller 17 has evenly distributed protrusions. One end of the rotating shaft 16 extends to the outside of the screening box 3 and is fixedly connected to a synchronous pulley 18. The rotating shaft 10 and the synchronous pulley 18 on the rotating shaft 16 are both driven by a synchronous belt 19. During operation, the synchronous pulley 18 on the rotating shaft 10 and the synchronous pulley 18 on the rotating shaft 16 rotate synchronously under the drive of the synchronous belt 19, so that the rotating shaft 16 rotates with the rotating shaft 10, thereby causing the rotating roller 17 to rotate. The protrusions on the rotating roller 17 prevent the grinding media from clogging the channel between the mounting plate 5 and the inner wall of the screening box 3.

[0030] Working principle: The worker puts the grinding media into the screening box 3 through the feed inlet 4, so that the grinding media rolls down along the uppermost filter plate 6 after entering. After the first round of screening, the grinding media enters the channel formed by the mounting plate 5 and the inner wall of the screening box 3. Then, the grinding media falls onto the next layer of filter plates 6 and continues to roll. This process is repeated. After multiple rounds of screening, the grinding media enters the ball mill cylinder 2 to complete the subsequent grinding operation. Through the cooperation of the synchronous pulley 18 and the synchronous belt 19, when the motor 9 drives one of the rotating shafts 10 to rotate, the other rotating shafts 10 rotate accordingly. When the cam 11 rotates with the rotating shaft 10 and presses the filter plate 6 upward, the filter plate 6 drives the top support rod 13 to slide upward and compress the spring 14. When the cam 11 moves away from the filter plate 6, the filter plate 6 quickly returns to its original position under the elastic force of the spring 14 until the cam 11 presses the filter plate 6 again. This process is repeated to realize the up-and-down vibration of the filter plate 6. When the filter plate 6 vibrates, it falls out of the through hole 7. The crushed grinding media falling onto the mounting plate 5 is discharged from the discharge pipe 20 and finally flows into the discharge pipe 21, from which it is discharged. The synchronous wheel 18 on the rotating shaft 26 rotates synchronously under the drive of the synchronous belt 19, causing the rotating shaft 26 to rotate with the rotating shaft 10, which in turn causes the rotating roller 17 to rotate, thus clearing the channel between the mounting plate 5 and the inner wall of the screening box 3. By setting the weir plate 15 on the mounting plate 5, the residence time of the grinding media on the filter plate 6 is increased, improving the screening effect. When the grinding is finished and the residual grinding media in the screening box 3 needs to be removed, the electromagnet 22 is energized, causing the permanent magnet 23 to drive the weir plate 15 to slide downward under the magnetic attraction and compress the spring 24. The top of the weir plate 15 is in contact with the top of the mounting plate 5 until the grinding media is completely discharged. Then the electromagnet 22 is de-energized, and the weir plate 15 is driven to slide upward and reset under the elastic force of the spring, facilitating the next screening of the grinding media.
