Description

Technical Field

[0001] This invention relates to the field of carbon black processing technology, specifically to a conveying device for carbon black. Background Technology

[0002] Carbon black is a black powder composed of carbon elements, usually produced by the incomplete combustion or thermal decomposition of hydrocarbons. It 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 equipment (such as screw conveyors and pneumatic conveying systems) plays a key role in efficiently and safely transferring carbon black powder between different processes, ensuring the continuity and stability of the production process, while reducing dust pollution and material loss.

[0003] Several utility model patents in the field of carbon black production technology are disclosed in the prior art. Among them, utility model patent with publication number CN221625179U discloses a conveying device for carbon black production. Specifically, this utility model discloses a conveying device for carbon black production, relating to the field of carbon black production technology. It includes a moving component, a conveying mechanism fixedly installed on the surface of the moving component, a feeding mechanism fixedly installed on the top surface of the moving component, a screening component located below the conveying mechanism on the moving component, and a cleaning mechanism fixedly installed on one side of the screening component. This utility model, by setting up the screening component, can screen the carbon black falling from the conveyor belt through the filter plate on the filter box, allowing larger particles to be moved out by tilting, while smaller particles enter the filter box, thus facilitating removal by the cleaning mechanism. By setting up the cleaning mechanism, a dust collector, in conjunction with a connecting conduit, can absorb the fine carbon black on the filter box and the carbon black on the surface of the conveyor belt, and then guide it into a storage box for storage, effectively reducing the impact of carbon black adhesion on the device over long-term use.

[0004] However, the existing conveying equipment for carbon black has the following shortcomings:

[0005] 1. In the process of conveying carbon black materials, traditional bucket conveyors are prone to large-scale dispersion during the feeding stage due to the physical characteristics of carbon black itself, such as small particle size, light weight, poor flowability and easy moisture absorption. This dispersion not only leads to a large loss of carbon black materials and increases production costs, but also forms a high concentration of suspended particles in the working area, causing pollution to the on-site environment. In severe cases, it may even cause safety hazards such as dust explosions. At the same time, the dispersed carbon black dust is easily inhaled by on-site workers, causing respiratory system hazards and affecting occupational health.

[0006] 2. In the feeding stage of the bucket conveyor, due to the lack of an effective flow control mechanism when feeding manually or mechanically, carbon black often accumulates in large quantities at the feed inlet in an unstable and uneven state. As a result, the material cannot enter the bucket elevator smoothly, causing some carbon black to be pre-entered into the conveyor belt or fall around the equipment during the conveying process, resulting in re-scattering. More seriously, excessive carbon black accumulation is very prone to sticking and clumping under high humidity or static electricity accumulation conditions, which can cause blockage at the feed inlet, affect the continuous operation efficiency of the entire conveying system, and increase the workload of equipment cleaning and maintenance. Summary of the Invention

[0020] 1. This invention, through the setting of a smoothing device and a compaction device, ensures that as carbon black enters the storage box from the hopper, the hopper continuously runs along the conveyor belt. During operation, the upper surface of the hopper applies pressure 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, with the first rotating shaft as its rotation fulcrum, swings and pushes the first telescopic rod to retract, simultaneously driving the second and third rotating shafts to rotate and compressing the return spring. During this stage, the friction ring rolls to the upper surface of the hopper and moves along its surface, while simultaneously driving the pressure roller to rotate in coordination, thus scraping off excess carbon black from the hopper surface. The carbon black is then introduced into the storage box. At the same time, the first motor drives the rotating rod to rotate within the first bearing, causing the rotating rod to drive the eccentric block to rotate at high speed. The centrifugal force generated by the eccentric block drives the slider to slide back and forth in the groove. The compression spring applies elastic force to the slider to ensure that the slider quickly returns to its original position. During this process, the slider moves in conjunction with the second bearing, and the second bearing... The drive bar and vertical bar move in tandem. The vertical bar slides along the axial direction of the sleeve, which in turn moves the sleeve and the ball. When the pressure roller rotates to the position of the ball, the ball applies vertical pressure to the pressure roller, causing the pressure roller to push the second telescopic rod to retract and compress the return spring. This creates a relative offset between the pressure roller and the friction rings on both sides. This offset allows the pressure roller to apply pressure to the carbon black in the hopper, ensuring that the carbon black is in clumps. This effectively prevents the carbon black from scattering during transportation and unloading. After the hopper passes the pressure roller, the second rotating shaft drives the rotating plate to quickly rebound under the action of the return spring, preparing for the processing of the next hopper. Through the combination of smoothing and compaction, excess carbon black outside the hopper can be efficiently removed, and the carbon black inside the hopper can be shaped and compacted. This significantly reduces the problem of carbon black scattering during transportation and unloading, saving raw materials, reducing cleaning and maintenance costs, and significantly improving the dust pollution problem in the working environment, protecting the occupational health of operators.

[0021] 2. This invention, through the setting of a feeding device, after carbon black is added to the feeding box, starts a second motor, which drives an eccentric wheel to rotate. During rotation, the eccentric wheel generates periodic centrifugal force, driving the locking plate to reciprocate. The reciprocating locking plate applies dynamic impact to the shock absorber, causing the shock absorber to be in a continuous compression and reset cycle, 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 reciprocate, and the inclined plate further drives the discharge pipe to perform axial extension and retraction within the feeding box, achieving continuous capture of the carbon black material. The received carbon black is discharged through the discharge... The material enters the corrugated pipe and is finally conveyed into the storage box. This structure enables stable and continuous feeding of carbon black. Due to the dynamic expansion and contraction of the discharge pipe and the cooperation of the inclined plate, the accumulation and blockage of carbon black in the feed box are effectively avoided, improving the overall feeding efficiency and system reliability. The feeding device enables continuous and stable feeding of carbon black material, avoiding blockage or scattering caused by excessive accumulation at one time. The system has built-in buffering and rhythm adjustment functions during the conveying process, improving the stability of material flow and effectively ensuring the continuous and efficient operation of the entire conveying system, reducing manual intervention and blockage cleaning time.

One end of return spring 507 is fixedly connected to the outside of third rotating shaft 506, and the other end of return spring 507 is fixedly connected to the outside of second rotating shaft 504. Compaction device 6 also includes two vertical plates 601, sliding plate 603, two second bearings 610, four compression springs 607, two horizontal bars 611, vertical bars 612, sliding sleeve 613, sleeve 614, and ball 615. The two vertical plates 601 are fixedly connected to the upper surface of storage box 4. Each of the two vertical plates 601 has a groove 602. Sliding plate 603 is fixedly connected to the groove 602. Sliding block 604 is slidably connected to the outside of sliding plate 603. Inside the slide groove 602, two compression springs 607 are respectively installed on the upper and lower surfaces of the slider 604, and the other end of the compression springs 607 is fixedly connected inside the slide groove 602. Two second bearings 610 are sleeved outside the rotating rod 606. Two horizontal rods 611 are respectively connected to the two second bearings 610. The vertical rod 612 is fixedly connected inside the two horizontal rods 611. The sleeve 614 is fixedly connected to the lower end of the vertical rod 612. A ball 615 is provided inside the sleeve 614. A sliding sleeve 613 is sleeved outside the vertical rod 612 and forms a sliding connection with the vertical rod 612. The sliding sleeve 613 is connected through the storage box 4. The size of the ball 615 is slightly smaller than the cross-section of the sleeve 614, and the two form a movable connection.

[0036] The overall effect of Embodiment 1 is as follows: During the process of carbon black entering the storage box 4 with the hopper 3, the hopper 3 continuously runs along the conveyor belt 2. During the operation, the upper surface of the hopper 3 applies a squeezing 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 uses the first rotating shaft 502 as the fulcrum of rotation, and pushes the first telescopic rod 505 to retract through its swing, while driving the second rotating shaft 504 and the third rotating shaft 506 to rotate, and compressing the return spring 507. During this stage, the friction ring 511... 1. The material rolls to the upper surface of hopper 3 and moves along its surface, while simultaneously driving the pressure roller 512 to rotate, thus scraping off excess carbon black from the surface of hopper 3. The carbon black is then 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 high speed. The centrifugal force generated by the eccentric block 609 drives the slider 604 to slide back and forth in the slide groove 602. The compression spring 607 applies elastic force to the slider 604 to ensure that the slider 604 quickly returns to its original position. During this process, the slider 604 is linked to the second shaft. As the second bearing 610 moves, it drives the horizontal bar 611 and the vertical bar 612 to move in tandem. The vertical bar 612 slides axially along the sliding sleeve 613, thereby moving the housing 614 and the ball 615. When the pressure roller 512 rotates to the position of the ball 615, the ball 615 applies vertical pressure to the pressure roller 512, causing the pressure roller 512 to push the second telescopic rod 513 to retract and compress the return spring 514, creating a relative offset between the pressure roller 512 and the friction rings 511 on both sides. This offset state allows the pressure roller 512 to apply pressure to the carbon black in the hopper 3, ensuring the carbon... The carbon black is formed into clumps, thus effectively preventing the carbon black from scattering during transportation and unloading. After passing through the pressure roller 512, the second rotating shaft 504 drives the rotating plate 503 to quickly rebound under the action of the return spring 507, preparing for the next processing of the hopper 3. Through the combination of smoothing and compaction, excess carbon black on the outside of 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 unloading. This not only saves raw materials and reduces cleaning and maintenance costs, but also significantly improves the dust pollution problem in the working environment.

[0037] It should be noted that the friction ring 511 rotates synchronously with the pressure roller 512 during rolling, enabling the pressure roller 512 to maintain a stable rhythm in contact with the surface of the hopper 3 for compaction. This cooperation ensures that the pressure roller 512 maintains uniform force even with slight differences in the surface height of different hoppers 3, thereby improving the synchronous efficiency of carbon black surface scraping and internal compaction, and avoiding local residue or incomplete compaction due to uneven pressure. When the slider 604 reciprocates in the groove 602, it drives the second bearing 610 to slide linearly, realizing the linear sliding of the horizontal bar 611 and the vertical bar 61. The precise drive of the 2-axis and the smooth linkage between the two improve the response speed and stability of the action, enabling the entire mechanism to complete a compaction cycle in a short time. At the same time, it improves the mechanical life and repeatability of the system. When the ball 615 is driven above the pressure roller 512 by the vertical rod 612, it applies vertical pressure to 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, while ensuring that the action of the pressure roller 512 is more compliant, which is conducive to the full compaction of carbon black.

[0038] 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, and 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 set inside the feed box 702 and is fixedly connected to the outside of the inclined surface of the inclined plate 706. The corrugated pipe 708 is sleeved on the outside of 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. The discharge pipe 707 and the feed box 702 form a sliding connection. The corrugated pipe 708 is connected through the storage box 4.

[0039] The overall effect of Embodiment 2 is as follows: After 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, the eccentric wheel 710 generates periodic centrifugal force, which drives the locking plate 705 to reciprocate. The reciprocating locking plate 705 applies dynamic impact to 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 move back and forth. The inclined plate 706 further drives the discharge pipe 707 to perform axial extension and retraction within the feed box 702, thereby achieving the holding of the carbon black material. Continuing to capture, 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 achieves stable and continuous feeding of carbon black. Due to the dynamic expansion and contraction of the discharge pipe 707 and the cooperation of the inclined plate 706, the phenomenon of carbon black accumulating and clogging in the feed box 702 is effectively avoided, improving the overall feeding efficiency and system operation reliability. Through this feeding device 7, the continuous and stable feeding of carbon black material can be achieved, avoiding clogging or scattering caused by excessive accumulation at one time. The system has built-in buffering and rhythm adjustment functions during the conveying process, improving the stability of material flow, effectively ensuring the continuous and efficient operation of the entire conveying system, and reducing manual intervention and clogging cleaning time.

[0040] 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, applying a nonlinear swaying force to the locking plate 705. This cooperation structure avoids the single rhythm of traditional rigid drive, giving the locking plate 705 a more natural disturbance 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 blockage; the cooperation between the inclined plate 706 and the discharge pipe 707: the inclined plate 706 reciprocates under the drive of the locking plate 705, thus completely... The periodic expansion and contraction of the corrugated pipe 708 enables intermittent absorption of carbon black. This combination of expansion and contraction creates rhythmic control over the material flow, ensuring that the carbon black is segmented before entering the corrugated pipe 708. This effectively avoids the blockage risks associated with continuous material accumulation and improves the efficiency and stability of each carbon black transport. The corrugated pipe 708, with its excellent flexibility and buffering properties, can adapt to the connection requirements of the discharge pipe 707 under different expansion and contraction states. This combination ensures that material backflow or leakage will not occur during discharge due to connection stress, improving the stability and sealing of the conveying process.

[0041] The working principle of the entire equipment is as follows: Carbon black is first added to the feed box 702 through the feeding device 7. After the second motor 709 is started, the eccentric wheel 710 rotates and generates periodic centrifugal force to drive the locking plate 705 to shake. The locking plate 705 applies impact force to cause the shock absorber 704 to reciprocate and compress to reset, and drives the inclined plate 706 to reciprocate. The inclined plate 706 drives the discharge pipe 707 to extend and retract within the feed box 702, continuously conveying the carbon black to the corrugated pipe 708, and finally into the storage box 4, completing the stabilization process. After the carbon black enters the storage box 4, it moves along the conveyor belt 2 with the hopper 3. During operation, the upper surface of the hopper 3 comes into contact with the friction ring 511 and the pressure roller 512, applying pressure to cause the friction ring 511 to drive the fifth rotating shaft 510 and the rotating plate 503 to rotate. The rotating plate 503 drives the first telescopic rod 505 to retract with the first rotating shaft 502 as the fulcrum, and also drives the second rotating shaft 504 and the third rotating shaft 506 to rotate, compressing the return spring 507. During this stage, the friction ring 511 rolls along the upper surface of the hopper 3. Simultaneously, the pressure roller 512 is driven to rotate synchronously, scraping off excess carbon black from the surface of the hopper 3. Simultaneously, the first motor 608 drives the rotating rod 606 to rotate within 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 within the groove 602. The slider 604 is quickly reset by the compression spring 607, causing the second bearing 610, the horizontal rod 611, and the vertical rod 612 to move sequentially. The vertical rod 612 moves along the sliding sleeve 613, further driving the housing 614 and... When the ball 615 moves, and the pressure roller 512 rotates to a position below the ball 615, the ball 615 applies pressure to it, causing the pressure roller 512 to compress the second telescopic rod 513 and the return spring 514, resulting in a relative offset between the pressure roller 512 and the friction ring 511. This offset causes the pressure roller 512 to apply pressure to the carbon black in the hopper 3, thereby compacting the carbon black into lumps. After the hopper 3 passes the pressure roller 512, the reset spring 507 drives the rotating plate 503 and related mechanisms to reset, preparing for the next hopper 3 processing cycle.
