Description

Technical Field

[0001] This utility model relates to the field of boron carbide drying technology, and more specifically, to a high-efficiency drying device for boron carbide coarse abrasive particles. Background Technology

[0002] In modern industrial production, boron carbide fine powder is widely used in various fields as an important high-performance material. However, boron carbide coarse abrasive particles often contain a certain amount of moisture during production and processing, which not only affects its performance and quality but may also cause problems in subsequent use. Therefore, it is necessary to use a boron carbide coarse abrasive particle drying device. In existing drying equipment, material is first discharged into the drying tower. Then, the boron carbide coarse abrasive particles are dispersed through multiple dispersing screens installed inside the drying tower. Hot air is injected from the bottom wall of the drying tower and flows from the bottom wall to the top of the drying tower, thereby drying the boron carbide coarse abrasive particles that are dispersed downward through the dispersing screens. However, when the feeding speed is too fast, the constant hot air velocity will affect the drying effect of the boron carbide coarse abrasive particles, causing the blower to be in a high-power state. Sometimes, this will lead to a large load on the blower, which will affect its service life or even burn it out.

[0003] Therefore, a high-efficiency drying device for boron carbide coarse abrasive particles is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency drying device for boron carbide coarse abrasive particles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency drying device for boron carbide coarse abrasive particles, comprising a drying tower, a feeding elevator on one side of the drying tower, a discharge pipe for the elevator connected to the top of the feeding elevator, a rotating shaft rotatably connected inside the drying tower, multiple partitions fixedly mounted on the outer wall of the rotating shaft, two turntables symmetrically fixedly mounted on the outer wall of the rotating shaft, and the two ends of the multiple partitions respectively fixedly connected to the two turntables, one end of the rotating shaft rotatably passing through the side wall of the drying tower, an angular velocity sensor connected to one end of the rotating shaft, the angular velocity sensor being fixedly mounted on the outer wall of the drying tower by bolts, a signal controller fixedly mounted on the outer wall of the drying tower next to the angular velocity sensor, a heater on one side of the lower end of the drying tower, a blower on one side of the heater, and the output end of the blower connected to the heater. In operation, the device introduces boron carbide coarse abrasive particles into the drying tower through the elevator discharge pipe. These particles then fall between multiple baffles on the outer wall of the rotating shaft. The gravity generated by the falling particles between the baffles drives the baffles, the rotating shaft, and the turntable to rotate. An angular velocity sensor detects the rotational speed of the shaft. As the velocity of the boron carbide particles entering the drying tower increases, the detected shaft speed also increases. When the shaft speed is high, the signal controller can increase the power of the blower and heater to better dry the boron carbide particles. When the velocity of the boron carbide particles decreases, the signal controller reduces the power of the blower and heater to prevent prolonged high-power operation, which could damage them and shorten their lifespan.

[0006] Preferably, the other side wall of the heater is connected to the side wall of the drying tower via an air supply pipe. Two sets of first support legs are symmetrically arranged on the outer side wall of the bottom end of the heater to support the heater. The hot air in the heater can be discharged into the drying tower through the air supply pipe, thereby drying the boron carbide coarse abrasive particles inside the drying tower.

[0007] Preferably, the end of the elevator discharge pipe near the drying tower is fixedly inserted through the top of the drying tower and extends into the interior of the drying tower. The bottom of the feeding elevator is fixedly connected to the elevator feed port, through which boron carbide coarse abrasive particles are discharged into the drying tower. Then, the feeding elevator lifts the discharged boron carbide coarse abrasive particles and finally discharges them into the drying tower through the elevator discharge pipe.

[0008] Preferably, the drying tower is equipped with multiple dispersing screens at an incline, and a material discharge port is fixedly provided at the bottom of the drying tower. Four third support legs are fixedly connected to the outer wall of the lower end of the drying tower. In use, hot air rises evenly from the bottom of the drying tower and exchanges heat in the opposite direction with the boron carbide coarse abrasive particles falling from the dispersing screens. This heat flow efficiently removes the moisture from the boron carbide coarse abrasive particles, and the moisture is directly discharged through the skylight at the top of the tower.

[0009] Preferably, a dust collection hood is fixedly installed at the top of the drying tower, and a connecting pipe is fixedly connected to the top of the dust collection hood. The dust in the drying tower is discharged through the cooperation of the dust collection hood and the connecting pipe and discharged into the dust collector for filtration.

[0010] Preferably, a dust collector is provided on one side of the drying tower, and the end of the connecting pipe near the dust collector is connected to the side wall of the dust collector. An induced draft connecting pipe is connected to the other side wall of the dust collector. An induced draft fan is provided on one side of the dust collector, and the end of the induced draft connecting pipe near the induced draft fan is connected to the input end of the induced draft fan. The dust discharged from the drying tower is filtered through the connecting pipe, and at the same time, the induced draft fan draws the dust in the drying tower through the induced draft connecting pipe, so that the dust can enter the dust collector for filtration.

[0011] Preferably, the dust collector is fixedly connected to a dust outlet at its bottom end, and a plurality of second support legs are fixedly provided on the outer side wall of the lower end of the dust collector to support the dust collector. The dust outlet allows the filtered impurities inside the dust collector to be discharged.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this high-efficiency drying device for boron carbide coarse abrasive particles uses a signal controller to adaptively control and adjust the power of the blower and heater by varying the speed of the boron carbide coarse abrasive particles introduced into the drying tower. This allows for better drying of the discharged boron carbide coarse abrasive particles while avoiding damage to the blower and heater caused by prolonged high-power operation.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] As attached Figures 1 to 4 The boron carbide coarse abrasive grain high-efficiency drying device shown includes a drying tower 1. A feeding elevator 11 is provided on one side of the drying tower 1. The output end of the feeding elevator 11 is connected to the top of the drying tower 1 and a discharge pipe 12 is provided. A rotating shaft 2 is rotatably connected inside the drying tower 1. Multiple partitions 3 are fixedly provided on the outer wall of the rotating shaft 2. Two turntables 4 are symmetrically fixedly connected to the outer wall of the rotating shaft 2, and the two ends of the multiple partitions 3 are respectively fixedly connected to the two turntables 4. One end of the rotating shaft 2 rotates through the side wall of the drying tower 1. An angular velocity sensor 5 is connected to one end of the rotating shaft 2. The angular velocity sensor 5 is fixedly provided on the outer wall of the drying tower 1 by bolts. A signal controller 6 is fixedly provided on the outer wall of the drying tower 1 and on the side of the angular velocity sensor 5. A heater 8 is provided on one side of the lower end of the drying tower 1. A blower 7 is provided on one side of the heater 8. The output end of the blower 7 is connected to the heater 8. The other side wall of the heater 8 is connected to the side wall of the drying tower 1 through an air supply pipe 9. Two sets of first support legs 10 are symmetrically provided on the outer wall of the bottom end of the heater 8 to support the heater 8.

[0020] In operation, the device introduces boron carbide coarse abrasive particles into the drying tower 1 through the elevator discharge pipe 12. These particles then fall between multiple baffles 3 on the outer wall of the rotating shaft 2. The gravity generated by the falling particles between two baffles 3 drives the baffles 3, the rotating shaft 2, and the turntable 4 to rotate. An angular velocity sensor 5 detects the rotational speed of the rotating shaft 2. As the speed of the boron carbide coarse abrasive particles entering the drying tower 1 increases, the speed of the rotating shaft 2 detected by the angular velocity sensor 5 also increases. Finally, when the rotating shaft 2 rotates at a high speed, the signal controller 6 can increase the power of the blower 7 and the heater 8 to better dry the boron carbide coarse abrasive particles introduced into the drying tower 1. When the speed of the boron carbide coarse abrasive particles entering the drying tower 1 decreases, the signal controller 6 reduces the power of the blower 7 and the heater 8 to prevent prolonged high-power operation, which could damage them and affect their service life. Example

[0021] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the end of the elevator discharge pipe 12 near the drying tower 1 is fixedly inserted through the top of the drying tower 1 and extends into the interior of the drying tower 1. The bottom of the feeding elevator 11 is fixedly connected to the elevator feed port 13. Boron carbide coarse abrasive particles are discharged into the drying tower 1 through the elevator feed port 13. Then, the feeding elevator 11 lifts the discharged boron carbide coarse abrasive particles and finally discharges them into the drying tower 1 through the elevator discharge pipe 12.

[0022] In a preferred embodiment, multiple dispersing screens 23 are fixedly and inclined inside the drying tower 1, a material discharge port 21 is fixedly provided at the bottom of the drying tower 1, and four third support legs 20 are fixedly connected to the outer wall of the lower end of the drying tower 1. When in use, hot air rises evenly from the bottom of the drying tower 1 and exchanges heat in the opposite direction with the boron carbide coarse abrasive particles falling up and down on the dispersing screens 23. This heat flow efficiently removes the moisture from the boron carbide coarse abrasive particles, and the moisture is directly discharged through the skylight at the top of the tower.

[0023] In a preferred embodiment, a dust collection hood 14 is fixedly installed at the top of the drying tower 1, and a connecting pipe 15 is fixedly connected to the top of the dust collection hood 14. Dust inside the drying tower 1 is discharged through the cooperation of the dust collection hood 14 and the connecting pipe 15 and discharged into the dust collector 16 for filtration. Then, a dust collector 16 is installed on one side of the drying tower 1. One end of the connecting pipe 15 near the dust collector 16 is connected to the side wall of the dust collector 16, and an exhaust fan connecting pipe 17 is connected to the other side wall of the dust collector 16. An exhaust fan connecting pipe 17 is installed on one side of the dust collector 16. The blower 18 and the exhaust pipe 17 are connected to the input end of the blower 18 at one end. The dust collector 16 is fixedly connected to the bottom end of the dust collector 16 and multiple second support legs 19 are fixedly installed on the outer side wall of the lower end of the dust collector 16 to support the dust collector 16. The dust discharged from the drying tower 1 is filtered through the connecting pipe 15. At the same time, the blower 18 pulls the dust in the drying tower 1 through the exhaust pipe 17, so that the dust can enter the dust collector 16 for filtration.

[0024] In this embodiment, the angular velocity sensor 5, signal controller 6, blower 7, heater 8, feeding elevator 11, dust collector 16, and induced draft fan 18 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not elaborate further.

[0025] The working process of this utility model is as follows: First, the boron carbide coarse abrasive particles are fed into the feeding elevator 11 through the feeding port 13 of the elevator. Then, the boron carbide coarse abrasive particles are lifted by the feeding elevator 11 and put into the drying tower 1 through the discharge pipe 12 of the elevator. Subsequently, the introduced boron carbide coarse abrasive particles will fall between multiple partitions 3 set on the outer wall of the rotating shaft 2. The gravity generated by the boron carbide coarse abrasive particles falling between two partitions 3 will drive the partitions 3, the rotating shaft 2, and the turntable 4 to rotate. Then, the angular velocity sensor 5 detects the rotation speed of the rotating shaft 2. The angular velocity sensor 5 converts the detected rotation speed of the rotating shaft 2 into an electrical signal. Then, the signal controller 6 receives and analyzes the electrical signal.

[0026] As the velocity of the boron carbide coarse abrasive particles discharged into the drying tower 1 increases, the rotational speed of the shaft 2 detected by the angular velocity sensor 5 also increases. At this time, the signal controller 6 can increase the power of the blower 7 and the heater 8 when the shaft 2 rotates at a higher speed, thereby increasing the temperature and rate of the hot air and thus better drying the boron carbide coarse abrasive particles introduced into the drying tower 1. When the velocity of the boron carbide coarse abrasive particles discharged into the drying tower 1 decreases, the signal controller 6 reduces the power of the blower 7 and the heater 8 to avoid prolonged high-power operation of the blower 7 and the heater 8, which could damage them and affect their service life. This structure can adaptively adjust the power of the blower 7 and the heater 8 according to the discharge speed into the drying tower 1, thereby better drying the discharged boron carbide coarse abrasive particles. The above is the working principle of this high-efficiency drying device for boron carbide coarse abrasive particles.
