Description

Technical Field

[0001] The present invention relates to the technical field of carbon black processing, and particularly to a conveying device for carbon black. Background Art

[0002] Carbon black is a black powder composed of carbon elements, usually obtained by incomplete combustion or thermal decomposition of hydrocarbon substances, and is widely used in industries such as rubber, plastics, inks, and coatings to enhance the strength, wear resistance, and coloring properties of materials. In the production and processing of carbon black, conveying devices (such as screw conveyors, pneumatic conveying systems, etc.) play a key role in efficiently and safely transporting carbon black powder between different processes, ensuring the continuity and stability of the production process, while reducing dust pollution and material loss.

[0003] Some utility model patents in the technical field of carbon black production are disclosed in the prior art. Among them, the utility model patent with the publication number CN221625179U discloses a conveying device for carbon black production, which is specifically described as follows: The utility model discloses a conveying device for carbon black production, which relates to the technical field of carbon black production, and includes a moving component. A conveying mechanism is fixedly installed on the surface of the moving component, a blanking mechanism is fixedly installed on the top surface of the moving component, a screening component is arranged below the moving component near the conveying mechanism, and a cleaning mechanism is fixedly installed on one side of the screening component. By setting the screening component, the carbon black falling on the conveyor belt can be screened through the filter plate on the filter box, so that the larger ones can be removed due to inclination, while the smaller ones enter the filter box, thereby being able to cooperate with the cleaning mechanism for cleaning. By setting the cleaning mechanism, the fine carbon black on the filter box and the carbon black on the surface of the conveyor belt can be absorbed by using a dust collector in cooperation with a connecting conduit, and then introduced into the storage box for storage, effectively reducing the influence of carbon black adhesion on the device during long-term use.

[0004] However, there are the following deficiencies in an existing conveying device for carbon black: 1. During the process of conveying carbon black materials by a traditional bucket conveyor, due to the physical characteristics of carbon black itself, such as fine particles, light specific gravity, poor fluidity, and easy moisture absorption, a large-area dispersion phenomenon is extremely likely to occur during the blanking stage. This dispersion not only causes a large amount of loss of carbon black materials, increases production costs, but also forms high-concentration suspended particles in the working area, pollutes the on-site environment, and may even cause safety hazards such as dust explosions in severe cases. At the same time, the dispersed carbon black dust is extremely easy to be inhaled by on-site operators, causing harm to the respiratory system and affecting occupational health.

[0005] 2. In the feeding link of the bucket conveyor, due to the lack of effective flow control mechanism during manual or mechanical feeding, carbon black is often concentrated in large quantities at the feeding port in an unstable and uneven state. As a result, the material cannot smoothly enter the bucket lifting device, causing part of the carbon black to be rolled into the conveyor belt in advance or fall around the equipment during the transmission process, resulting in re-dispersion. What is more serious is that excessive accumulation of carbon black is very likely to stick and agglomerate under high humidity or static electricity accumulation conditions, thereby causing blockage of the feeding port, affecting the continuous operation efficiency of the entire conveying system, and increasing the workload of equipment cleaning and maintenance.

[0006] Therefore, we propose a conveying device for carbon black in order to solve the problems mentioned above. Summary of the invention

[0017] Preferably, a sliding connection is formed between the discharge pipe and the feeding box. The corrugated pipe is connected through the storage box.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the provided leveling device and compaction device, when the carbon black enters the storage box along with the hopper, the hopper continuously runs along the conveyor belt. During the running process, the upper surface of the hopper applies an extrusion force to the friction ring and the pressure roller, causing the friction ring to drive the fifth rotating shaft and the rotating plate to rotate synchronously. The rotating plate takes the first rotating shaft as the rotation fulcrum, and through its swing, it pushes the first telescopic rod to contract, while driving the second rotating shaft and the third rotating shaft to rotate and compressing the return spring. At this stage, the friction ring rolls onto the upper surface of the hopper and moves along its surface, while driving the pressure roller to rotate together to achieve the scraping of the excess carbon black on the surface of the hopper. The carbon black is introduced into the storage box. At the same time, the first motor drives the rotating rod to rotate in the first bearing, and the rotating rod drives the eccentric block to rotate at a high speed. The centrifugal force generated by the eccentric block drives the slider to reciprocate in the chute. The extrusion spring applies an elastic force to the slider to ensure the quick reset of the slider. During this process, the slider drives the second bearing to move, and the second bearing then drives the cross bar and the vertical bar to move together. The vertical bar slides axially along the sliding sleeve, thereby driving the sleeve and the sphere to move. When the pressure roller rotates to the position of the sphere, the sphere applies a vertical pressure to the pressure roller, prompting the pressure roller to push the second telescopic rod to contract and compress the pulling-back spring, forming a relative offset between the pressure roller and the friction rings on both sides. This offset state enables the pressure roller to apply a compaction force to the carbon black in the hopper to ensure that the carbon black forms blocks, thereby effectively preventing the carbon black from scattering during transportation and feeding. After the hopper passes through the pressure roller, under the action of the return spring, the second rotating shaft drives the rotating plate to quickly rebound, preparing for the processing of the next hopper. Through the combined structure of leveling and compaction, the excess carbon black outside the hopper can be efficiently removed, and the carbon black inside the hopper can be shaped and compacted, significantly reducing the problem of carbon black scattering during transportation and feeding. It not only saves raw materials, reduces the cleaning and maintenance costs, but also significantly improves the dust pollution problem of the working environment and protects the occupational health of the operators.

[0019] 2. The present invention sets up a feeding device. After the carbon black is added to the feeding box, the second motor is started. The second motor drives the eccentric wheel to rotate. During the rotation of the eccentric wheel, a periodic centrifugal force is generated, driving the locking plate to swing reciprocally. The swinging locking plate exerts a dynamic impact on the shock absorber, causing the shock absorber to be in a continuous compression and reset cycle state, thereby driving the locking plate to achieve a rapid reset process. During this cycle, the movement of the locking plate drives the inclined plate to generate a reciprocating displacement, and the inclined plate further drives the discharge pipe to perform an axial telescopic movement inside the feeding box, realizing the continuous capture of the carbon black material. The received carbon black enters the corrugated pipe through the discharge pipe and is finally transported to the inside of the storage box. This structure realizes the stable and continuous feeding of carbon black. Moreover, due to the dynamic telescopic cooperation of the discharge pipe and the inclined plate, the phenomenon of carbon black accumulation and blockage in the feeding box is effectively avoided, improving the overall feeding efficiency and the reliability of the system operation. Through this feeding device, the continuous and stable feeding of the carbon black material can be realized, avoiding the situation of blockage or dispersion caused by excessive accumulation at one time. The system has a built-in buffering and rhythm adjustment function during the transportation process, improving the stability of the material flow and effectively ensuring the continuous and efficient operation of the entire transportation system, reducing manual intervention and the time for blockage cleaning.

The diameter of the sphere 615 is slightly less than the inner diameter of the cross-section of the housing 614, and the two form a movable connection fit.

[0025] The effect achieved by the entire Embodiment 1 is as follows: During the process of carbon black entering the storage box 4 along with the hopper 3, the hopper 3 continuously runs along the conveyor belt 2. During the running process, the upper surface of the hopper 3 applies an extrusion force to the friction ring 511 and the pressure roller 512, causing the friction ring 511 to drive the fifth rotating shaft 510 and the rotating plate 503 to rotate synchronously. The rotating plate 503 takes the first rotating shaft 502 as the rotation fulcrum, and through its swing, it pushes the first telescopic rod 505 to contract, while driving the second rotating shaft 504 and the third rotating shaft 506 to rotate, and compressing the return spring 507. At this stage, the friction ring 511 rolls onto the upper surface of the hopper 3 and moves along its surface, while driving the pressure roller 512 to rotate synchronously, realizing the scraping of the excess carbon black on the surface of the hopper 3. The carbon black is introduced into the storage box 4. At the same time, the first motor 608 drives the rotating rod 606 to rotate within the first bearing 605. The rotating rod 606 drives the eccentric block 609 to rotate at a high speed. The centrifugal force generated by the eccentric block 609 drives the slider 604 to reciprocate within the chute 602. The compression spring 607 applies an elastic force to the slider 604 to ensure the quick reset of the slider 604. During this process, the slider 604 drives the second bearing 610 to move. The second bearing 610 then drives the cross bar 611 and the vertical bar 612 to move in coordination. The vertical bar 612 slides axially along the sliding sleeve 613, thereby driving the housing 614 and the sphere 615 to move. When the pressure roller 512 rotates to the position of the sphere 615, the sphere 615 applies a vertical pressure to the pressure roller 512, prompting the pressure roller 512 to push the second telescopic rod 513 to contract and compress the pulling-back spring 514, forming a relative offset between the pressure roller 512 and the friction rings 511 on both sides. This offset state enables the pressure roller 512 to apply a compaction force to the carbon black in the hopper 3, ensuring that the carbon black forms blocks, thereby effectively preventing the carbon black from scattering during transportation and feeding. After the hopper 3 passes through the pressure roller 512, under the action of the return spring 507, the second rotating shaft 504 drives the rotating plate 503 to quickly rebound, preparing for the processing of the next hopper 3. Through the combined structure of smoothing and compaction, the excess carbon black outside the hopper 3 can be efficiently removed, and the carbon black inside the hopper 3 can be shaped and compacted, significantly reducing the problem of carbon black scattering during transportation and feeding. This not only saves raw materials, reduces the cleaning and maintenance costs, but also significantly improves the dust pollution problem in the working environment.

[0026] It should be noted that: during the rolling process, the friction ring 511 rotates synchronously with the pressure roller 512, enabling the pressure roller 512 to compact the surface of the hopper 3 at a stable rhythm. Through this cooperation relationship, it is ensured that the pressure roller 512 can still maintain uniform force under slight differences in the surface height of different hoppers 3, thereby improving the synchronous efficiency of scraping the surface of carbon black and internal compaction, and avoiding local residues or incomplete compaction caused by uneven pressure. When the slider 604 reciprocates in the chute 602, it drives the linear sliding of the second bearing 610, achieving precise drive of the cross bar 611 and the vertical bar 612. The smooth linkage between the two improves the response speed and stability of the action, enabling the entire mechanism to complete a compaction cycle in a short time, while also improving the mechanical life and action repetition accuracy of the system. When the sphere 615 is driven by the vertical bar 612 below the pressure roller 512, it exerts a vertical pressure on the pressure roller 512, indirectly guiding the second telescopic rod 513 to complete the compression action. This indirect drive structure has a certain flexible buffering effect, avoiding structural damage caused by rigid impact, and at the same time ensuring that the action of the pressure roller 512 is more compliant, which is beneficial to fully compacting the carbon black.

[0027] Example 2, according to Figure 8 As shown, the feeding device 7 includes a support frame 701, a feeding box 702, a connecting column 703, a shock absorber 704, a locking plate 705, an inclined plate 706, a discharge pipe 707, a corrugated pipe 708, a second motor 709, and an eccentric wheel 710. The support frame 701 is fixedly connected to the base 1, the feeding box 702 is connected through the support frame 701, the connecting column 703 is fixedly connected to the base 1, the shock absorber 704 is fixedly connected to the upper end of the connecting column 703, the locking plate 705 is fixedly connected to the shock absorber 704, the inclined plate 706 is fixedly connected to the upper surface of the locking plate 705, the discharge pipe 707 is arranged in the feeding box 702, the discharge pipe 707 is fixedly connected to the outer slope of the inclined plate 706, the corrugated pipe 708 is sleeved outside the discharge pipe 707, the second motor 709 is fixedly connected to the lower surface of the locking plate 705, the eccentric part of the eccentric wheel 710 is fixedly connected to the output end of the second motor 709, and a sliding connection fit is formed between the discharge pipe 707 and the feeding box 702. The corrugated pipe 708 is connected through the storage box 4.

[0028] The effect achieved by the entire Embodiment 2 is as follows: After the carbon black is added to the feed box 702, the second motor 709 is started. The second motor 709 drives the eccentric wheel 710 to rotate. During the rotation of the eccentric wheel 710, a periodic centrifugal force is generated, driving the locking plate 705 to sway reciprocally. The swaying locking plate 705 exerts a dynamic impact on the shock absorber 704, causing the shock absorber 704 to be in a continuous compression and reset cycle state, thereby driving the locking plate 705 to achieve a rapid reset process. During this cycle, the movement of the locking plate 705 drives the inclined plate 706 to generate reciprocating displacement, and the inclined plate 706 further drives the discharge pipe 707 to perform axial telescopic movement inside the feed box 702, realizing continuous capture of the carbon black material. The received carbon black enters the corrugated pipe 708 through the discharge pipe 707 and is finally transported to the storage box 4. This structure realizes stable and continuous feeding of carbon black. Moreover, due to the dynamic telescoping of the discharge pipe 707 cooperating with the inclined plate 706, the phenomenon of carbon black accumulation and blockage in the feed box 702 is effectively avoided, improving the overall feeding efficiency and the reliability of the system operation. Through this feeding device 7, continuous and stable feeding of the carbon black material can be achieved, avoiding the situation of blockage or dispersion caused by excessive accumulation at one time. The system has a built-in buffering and rhythm adjustment function during the transportation process, improving the stability of the material flow and effectively ensuring the continuous and efficient operation of the entire transportation system, reducing manual intervention and the time for blockage cleaning.

[0029] It should be noted that: The cooperation between the eccentric wheel 710 and the locking plate 705: During the rotation of the eccentric wheel 710, a periodic centrifugal force is continuously output, exerting a non-linear swaying force on the locking plate 705. This cooperation structure avoids the single rhythm of traditional rigid driving, making the movement of the locking plate 705 have a more natural perturbation characteristic, thereby increasing the response frequency of the shock absorber 704, making the feeding rhythm more stable and adaptable, and reducing the risk of discontinuous feeding caused by local material blockage; The cooperation between the inclined plate 706 and the discharge pipe 707: The inclined plate 706 realizes reciprocating sliding driven by the locking plate 705, and the discharge pipe 707 thus completes periodic telescoping, realizing intermittent absorption of the carbon black. The cooperation between the two forms a rhythm control of the material flow, ensuring that the carbon black has been segmented before entering the corrugated pipe 708, effectively avoiding the blockage hidden danger caused by continuous stacking of materials, and at the same time improving the efficiency and stability of each carbon black transportation; The cooperation between the corrugated pipe 708 and the discharge pipe 707: The corrugated pipe 708 has good flexibility and buffering performance, and can adapt to the connection requirements of the discharge pipe 707 in different telescopic states. This cooperation ensures that there will be no material backflow or leakage due to connection stress during the discharging process, improving the stability and sealing performance of the transportation process.

[0030] The working principle of the whole equipment is as follows: the carbon black is firstly added into the feed box 702 through the feed device 7, and after the second motor 709 is started, the eccentric wheel 710 rotates to generate periodic centrifugal force to drive the locking plate 705 to shake, and the locking plate 705 applies impact force to make the shock absorber 704 reciprocate and compress to reset, and drive the inclined plate 706 to produce reciprocating motion, and the inclined plate 706 drives the discharge pipe 707 to perform telescopic motion in the feed box 702, and continuously transports the carbon black to the bellows 708, and finally enters the storage box 4, completing the stable After the carbon black enters the storage box 4, it runs along the conveyor belt 2 with the hopper 3. During the operation, the upper surface of the hopper 3 comes into contact with the friction ring 511 and the pressure roller 512, and the extrusion force is applied to make the friction ring 511 drive the fifth rotating shaft 510 and the rotating plate 503 to rotate. The rotating plate 503 drives the first telescopic rod 505 to contract with the first rotating shaft 502 as a fulcrum, and links the second rotating shaft 504 and the third rotating shaft 506 to rotate, compressing the reset spring 507. At this stage, the friction ring 511 rolls along the upper surface of the hopper 3 , and at the same time, the pressing roller 512 is driven to rotate synchronously to scrape off the excess carbon black on the surface of the hopper 3. Synchronously, the first motor 608 drives the rotating rod 606 to rotate in the first bearing 605. The eccentric force generated by the rotation causes the eccentric block 609 to drive the slider 604 to slide back and forth in the slide groove 602. The slider 604 is quickly reset by the extrusion spring 607, driving the second bearing 610, the cross bar 611, and the vertical rod 612 to move in sequence. The vertical rod 612 moves along the sliding sleeve 613, further driving the sleeve shell 614 and The ball 615 moves, and when the pressure roller 512 rotates to the bottom of the ball 615, the ball 615 applies pressure to it, causing the pressure roller 512 to compress the second telescopic rod 513 and compress the pull-back spring 514, forming a relative offset between the pressure roller 512 and the friction ring 511. The offset enables the pressure roller 512 to apply compaction force to the carbon black in the hopper 3, thereby compacting the carbon black into blocks. After the hopper 3 passes through the pressure roller 512, the reset spring 507 drives the rotating plate 503 and related mechanisms to reset, thereby preparing for the next hopper 3 processing cycle.
