Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon black processing, in particular to a device for removing powder in carbon black particles. BACKGROUND

[0002] Carbon black is an important raw material for the rubber industry. With the development of the rubber industry, higher and higher requirements are put forward for carbon black as the main additive reinforcing agent of rubber. The carbon black particle product usually contains a certain amount of fine powder. Too high fine powder content not only causes pollution to product transportation, carbon black packaging environment and rubber mixing environment, but also affects carbon black packaging standards (caused by changes in apparent density leading to changes in packaging volume), and causes harm to the pneumatic conveying system of the rubber industry. At the same time, too high fine powder content will affect the dispersion of carbon black in the rubber and reduce the mechanical and physical properties of the rubber. Therefore, reducing the fine powder content in the carbon black particles has become a technical problem to be solved in the carbon black industry.

[0003] In the prior art, some methods and devices for removing powder in carbon black particles are disclosed. For example, the authorized patent document with the application number CN201821083057.2 discloses a carbon black finished product powder dust removal device. This scheme uses a vibrating sieve method to remove carbon black powder. In use, the mutual collision between carbon black particles makes the carbon black particles easy to break and form more fine powder. The fine powder is easy to block the sieve, affecting the carbon black sieving effect. To solve this problem, the authorized patent document with the application number CN200810132181.8 discloses a carbon black powder removal method and device. This method uses a wind selection method to remove powder between carbon black particles in a suspended state. In use, this type of scheme requires a large amount of air and has high energy consumption.

[0029] The top end of the inner side of the conveying belt one 18 is provided with a guide plate 16, the two ends of the inner cavity of the box body 1 are fixedly provided with blocking blocks 20, the guide plate 16 is located between the two blocking blocks 20, the end of the guide plate 16 is in contact with the blocking blocks 20, the side, away from the guide plate 16, of the blocking blocks 20 is provided with an arc-shaped groove, the conveying roller one 29 is movably connected with the inner cavity of the arc-shaped groove, and the top and the bottom of the blocking blocks 20 are in contact with the conveying belt one 18, through the arrangement of the blocking blocks 20, the blocking blocks 20 can support and limit the conveying belt one 18, so that when the carbon black particles move to the upper side of the guide plate 16, the powder can pass through the holes, the separation of the powder and the conveying belt one 18 is realized, and the powder passing through the holes falls on the guide plate 16 under the action of gravity.

[0030] The guide plate 16 is inclined, and its high end is equipped with a dust scraping structure. The low end of the guide plate 16 extends to the outside of the conveyor belt 18, and there is a dust collection gap between the bottom end of the guide plate 16 and the housing 1. The size of the dust collection gap is designed according to requirements and is not limited here. The dust scraping structure includes a scraper 19 movably connected to the side wall of the housing 1 and a hydraulic telescopic rod 7 fixedly connected to the scraper 19. The other end of the hydraulic telescopic rod 7 is fixedly connected to the housing 1, and the scraper 19 is connected to the output end of the hydraulic telescopic rod 7.

When the scraper 19 moves, it can move along the direction of the guide plate 16 and scrape off the powder that falls on the guide plate 16 to clean the powder on the guide plate 16, making it easier for the powder to fall onto the guide plate 16.

[0031] A back-blowing plate 21 is provided at the bottom of the inner cavity of the conveyor belt 18. The bottom of the back-blowing plate 21 contacts the conveyor belt 18, and dust blowing holes are evenly provided at the bottom of the inner cavity of the back-blowing plate 21. A back-blowing pipe 8 is fixed at one end of the inner cavity of the back-blowing plate 21, and the other end of the back-blowing pipe 8 extends to the outside of the box. An electric ball valve is provided at one end of the back-blowing pipe 8. The opening and closing of the back-blowing pipe 8 can be controlled by the electric ball valve. When back-blowing gas is introduced into the inner cavity of the back-blowing pipe 8, the back-blowing gas in the back-blowing pipe 8 can be blown onto the conveyor belt 18 through the dust blowing holes. The airflow blown out of the dust blowing holes can blow away the powder blocking the holes, thereby cleaning the conveyor belt 18 and preventing powder from clogging the conveyor belt 18.

[0032] A brush roller 22 is movably connected inside the inner cavity of the housing 1. The brush roller 22 contacts the bottom of the conveyor belt 18 away from the feed inlet 5, and the back-blowing plate 21 is located on the side of the brush roller 22 close to the feed inlet 5. When the device is working, the brush roller 22 is in a rotating state. The brush roller 22 can scrape off the powder adhering to the surface of the conveyor belt 18, thereby cleaning the conveyor belt 18 and facilitating the back-blowing of the conveyor belt 18.

[0033] The air separation structure includes a sealed box 2, a conveying structure 2, an ion fan 12, an exhaust fan 14, and a dust filter 4. A connecting groove 30 is provided on the side of the box 1 away from the feed inlet 5. The inner cavity of the box 1 is connected to the inner cavity of the sealed box 2 through the connecting groove 30. A discharge port 15 is provided at the bottom of the other end of the sealed box 2.

[0034] The second conveying structure includes two conveying rollers. One conveying roller is movably connected to the end of the housing 1 furthest from the inlet 5, and the other conveying roller is movably connected to the end of the sealed housing 2 near the outlet 15. The two conveying rollers are connected by a conveyor belt 25. One end of the conveyor belt 25 is located below the end of the first conveyor belt 18 furthest from the inlet 5, and the other end of the conveyor belt 25 is located above the outlet 15. Through the second conveying structure, the pre-treated carbon black particles fall onto the second conveying structure under gravity. The second conveying structure drives the carbon black particles to move within the inner cavity of the sealed housing 2. After air separation, the carbon black particles are discharged through the outlet 15. The second conveyor belt 25 is movably connected to the inner cavity of the connecting groove 30.

[0035] A baffle plate 23 is fixedly connected to the inner cavity of the housing 1 on the side near the second conveyor structure. The baffle plate 23 is located between the end of the first conveyor belt 18 away from the inlet 5 and the end of the second conveyor belt 25 away from the outlet 15. By setting the baffle plate 23, the second conveyor belt 25 can be intercepted to prevent the powder adhering to the first conveyor belt 18 from falling onto the second conveyor belt 25. The baffle plate 23 is inclined, and the powder falling on the baffle plate 23 can fall into the inner cavity of the housing 1 under the action of gravity.

[0036] The conveyor belt 25 is uniformly provided with air holes, and the size of the air holes is the same as that of the aforementioned holes. The inner side of the conveyor belt 25 is provided with a first dust blowing plate 24 and a second dust blowing plate 28. The first dust blowing plate 24 is located on the side of the second dust blowing plate 28 near the feed inlet. The top of the inner cavity of both the first dust blowing plate 24 and the second dust blowing plate 28 is uniformly provided with dust blowing holes. The air outlet of the ion blower 12 is connected to the inner cavity of the first dust blowing plate 24 through the air inlet pipe. Through the setting of the ion blower 12, the operation of the ion blower 12 can blow outside air into the inner cavity of the first dust blowing plate 24. The gas in the first dust blowing plate 24 is sprayed out through the dust blowing holes. The sprayed gas can be blown onto the carbon black particles through the air holes. The sprayed gas can blow away the powder adhering to the carbon black particles, thereby achieving secondary cleaning of the carbon black particles.

[0037] The air inlet of the exhaust fan 14 is connected to the inner cavity of the sealed box 2 via a dust extraction pipe 13. The air outlet of the exhaust fan 14 is connected to the second dust blowing plate 28 via a dust filter 4. One end of the dust extraction pipe 13 extends to the top of the inner cavity of the sealed box 2, and the other end of the dust extraction pipe 13 is connected to the air inlet of the exhaust fan 14. The air outlet of the exhaust fan 14 is connected to the air inlet of the dust filter 4 via an outlet pipe. The air outlet of the dust filter 4 is connected to the inner cavity of the second dust blowing plate 28 via a pipe. Through the configuration of the exhaust fan 14, the operation of the exhaust fan 14 can blow dust-laden air from the sealed box 2 into the dust filter 4. The dust filter 4 filters the air, and the filtered air enters the inner cavity of the second dust blowing plate 28. The air in the second dust blowing plate 28 is sprayed onto the surface of the carbon black particles through the dust blowing holes, achieving a third cleaning of the carbon black particles. The dust filter is existing technology and will not be described in detail here.

[0038] As described above, when the device is in use, the gas used for the third dust blowing of carbon black particles is recycled gas, which reduces the air consumption of the device and the energy consumption of the ion fan 12. Moreover, the carbon black particles are pre-filtered by the pretreatment structure, which greatly reduces the powder content between carbon black particles, thereby reducing the dust content in the dusty air and making it easier for the dust filter 4 to treat the air.

[0039] Conveying structure one, conveying structure two and brush roller 22 are connected by a linkage structure. The linkage structure is driven by servo motor 6. Servo motor 6 is fixedly connected to housing 1. The end of the output shaft of servo motor 6 is fixedly connected to a conveying roller 29 through a reducer. The rotation of servo motor 6 can drive the fixedly connected conveying roller 29 to rotate. The rotating conveying roller 29 can drive the other conveying roller 29 to rotate.

[0040] The linkage structure includes a first synchronous belt 11, a second synchronous belt 9, a driving gear and a driven gear movably connected to the housing 1, a third synchronous belt 10, and a servo motor 6. The output shaft end of the servo motor 6 is fixedly connected to the end of a first conveyor roller. The second conveyor roller and the adjacent second conveyor roller are connected by the first synchronous belt 11. The two adjacent brush rollers 22 are connected by the second synchronous belt 9. The end of one brush roller 22 is fixed with a driven gear. The driving gear meshes with the driven gear, and the driving gear is connected to the other first conveyor roller by the third synchronous belt 10. In some embodiments of this application, the ends of the other first conveyor roller and the adjacent second conveyor roller are both fixed with a first synchronous wheel. The two first synchronous wheels are connected by the first synchronous belt 11. The ends of the two adjacent brush rollers 22 are both fixed with a second synchronous wheel. The two second synchronous wheels are connected by the second synchronous belt 9. One second synchronous wheel is fixedly connected to the driven gear. The side of the driving gear away from the driven gear and the end of the first synchronous wheel connected to the other first conveyor roller are both fixed with a third synchronous wheel. The two third synchronous wheels are connected by the third synchronous belt 10.

[0041] As can be seen from the above description of the linkage structure, the rotation of the servo motor 6 can drive the rotation of another conveyor roller 29, which in turn can drive the rotation of the second conveyor roller via the synchronous belt 11, thus achieving synchronous movement of the first and second conveyor belts. The other conveyor roller 29 can drive the rotation of the drive gear via the synchronous belt 10, which in turn can drive the rotation of the second synchronous wheel via the driven gear meshing with it. The second synchronous wheel drives the brush roller to rotate, so that when the device is in use, the brush roller can brush the first conveyor belt 18.

[0042] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0043] In summary: When the powder removal device for carbon black granules is in use, the servo motor 6 operates. The servo motor 6 drives the first conveyor belt 18, the second conveyor belt 25, and the brush roller 22 to rotate simultaneously through the linkage structure. The carbon black granules to be processed are placed on the first conveyor belt 18 through the feed port 5. The first conveyor belt 18 transports the carbon black granules. During the transport process, the carbon black granules can come into contact with the brush belt 17. The bristles on the brush belt 17 can brush the carbon black granules, facilitating the separation of powder particles from carbon black. The brush belt 17 can also intercept the carbon black granules, allowing them to move slowly on the first conveyor belt 18 and accelerating the separation speed of carbon black powder from carbon black granules. The separated carbon black powder falls onto the guide plate 16. When the hydraulic telescopic rod 7 extends, it can drive the scraper 19, which is fixedly connected to it, to move. During the movement, the scraper 19 can scrape off the dust that has fallen onto the guide plate 16, thus cleaning the guide plate 16. After pretreatment, the carbon black particles fall onto conveyor belt 25 under gravity. Conveyor belt 25 continues to transport the carbon black particles. As the carbon black particles move on the first dust-blowing plate 24 and the second dust-blowing plate 28, the air containing a large number of evaporated ions sprayed by the first dust-blowing plate 24 or the second dust-blowing plate 28 can blow onto the carbon black particles, blowing away the powder adhering to the carbon black particles. The dust-laden air is blown into the dust filter 4 by the exhaust fan 14. The air filtered by the dust filter 4 enters the second dust-blowing plate 28, and the gas sprayed by the second dust-blowing plate 28 can blow away the carbon black particles for a third dust-blowing operation. The powder adhering to conveyor belt 18 is brushed off by the brush roller 22, and the powder clogging the holes is blown away by the gas blown by the back-blowing plate 21, thus cleaning conveyor belt 18 and facilitating the separation of carbon black particles and powder on conveyor belt 18.
