Description

Technical Field

[0001] This utility model relates to the technical field of carbon black processing equipment, specifically a feeding device for granulating carbon black. Background Technology

[0002] Carbon black is an important additive widely used in industries such as rubber, plastics, and coatings. Its characteristics, such as small particle size, low density, easy dispersion, and easy agglomeration, pose significant challenges to the material conveying and feeding process during granulation.

[0003] In traditional carbon black feeding devices, common problems include: material easily adsorbs onto the inner wall of the feeding cylinder, causing blockage; carbon black particles agglomerate and cannot pass smoothly through the discharge port, resulting in poor or interrupted feeding; equipment is difficult to clean and requires frequent shutdowns for maintenance, which not only affects production efficiency but also increases the intensity of manual labor and the risk of dust leakage.

[0004] In existing technologies, although some feeding devices have been designed to alleviate carbon black blockage by incorporating vibration structures or airflow assist devices, they still suffer from drawbacks such as complex structures, high energy consumption, and poor adaptability. In particular, during continuous granulation production, localized agglomeration can easily lead to the shutdown of the entire production line, reducing capacity utilization. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for granulated carbon black, so as to solve the problems of complex structure and poor anti-clogging effect of existing feeding devices mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for granulating carbon black, comprising a feeding device body, wherein the top of the feeding device body is respectively provided with an inner wall cleaning mechanism and an anti-blocking mechanism, the inner wall cleaning mechanism comprising a limiting plate, a cleaning brush and a scraper, wherein a cleaning brush is fixedly connected to the inner wall of the limiting plate near the feeding cylinder, and a scraper is fixedly connected to the inner wall of the limiting plate away from the feeding cylinder, and the anti-blocking mechanism comprises an extrusion block.

[0007] Furthermore, a separation screen is connected to the middle of the feeding device body, and a guide groove is fixedly connected to the front of the feeding device body.

[0008] Furthermore, a fixing plate is fixedly connected to the top of the feeding device body, and a feeding cylinder is fixedly connected to the inner side of the fixing plate.

[0009] Furthermore, a cover plate is snapped onto the top of the feed cylinder, a cover door is hinged to one side of the top of the cover plate, and a drive motor is fixedly connected to the top of the cover plate.

[0010] Furthermore, the output end of the drive motor passes through the cover plate and is fixedly connected to a drive rod, the bottom end of which is fixedly connected to a first connecting plate and a second connecting plate respectively.

[0011] Furthermore, the bottom end of the limiting plate is slidably connected to the top end of the first connecting plate, the top end of the limiting plate is slidably connected to the bottom end of the cover plate, and a stabilizing plate is fixedly connected between the top end of the first connecting plate and the cover plate.

[0012] Furthermore, a first reset spring rod is fixedly connected to the inner side of the stabilizing plate, and the free end of the first reset spring rod is fixedly connected to the inner side of the limiting plate. The outer side of the scraper and the outer side of the cleaning brush are both attached to the inner wall of the feeding cylinder.

[0013] Furthermore, a vertical plate is fixedly connected to the top of the second connecting plate, a second reset spring rod is fixedly connected to the inner side of the vertical plate, a rubber plate is fixedly connected to the free end of the second reset spring rod, and a pre-extrusion block is fixedly connected to the inner wall of the feed cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an inner wall cleaning mechanism on the top of the feeding device body, the cleaning brush and scraper are driven by the limiting plate to clean the inner wall of the feeding cylinder simultaneously. This effectively removes the residue of carbon black particles adhering to the inner wall, preventing blockage and uneven feeding caused by carbon black agglomeration during long-term operation. At the same time, an anti-blocking mechanism is set, including a rubber plate connected to the elastic reset component and a matching extrusion block. This mechanism can actively intervene when carbon black falls poorly or bridging occurs. Through the coordinated action of compression and relaxation, the blocked area is broken up, effectively improving the device's adaptability and feeding smoothness. In addition, the device structure is also equipped with a separation screen and a guide channel to facilitate the screening of impurities or particle agglomerates in the material, guiding the material to fall evenly, improving the stability and particle quality of subsequent granulation processes. The overall structure is compact and the various mechanisms work together efficiently, reducing manual intervention and cleaning frequency, improving production efficiency, and extending equipment life.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figures 1 to 4 As shown, a feeding device for granulated carbon black in the first aspect embodiment of the present invention includes a feeding device body 1. The top of the feeding device body 1 is respectively provided with an inner wall cleaning mechanism 5 and an anti-blocking mechanism 7. The inner wall cleaning mechanism 5 includes a limiting plate 508, a cleaning brush 504 and a scraper 507. The cleaning brush 504 is fixedly connected to the inner wall of the limiting plate 508 near the feeding cylinder 4, and the scraper 507 is fixedly connected to the side of the limiting plate away from the feeding cylinder 4. The anti-blocking mechanism 7 includes an extrusion block 704.

[0024] A separating screen 3 is connected to the middle of the feeding device body 1, and a guide channel 2 is fixedly connected to the front of the feeding device body 1.

[0025] A fixing plate 6 is fixedly connected to the top of the feeding device body 1, and a feeding cylinder 4 is fixedly connected to the inner side of the fixing plate 6.

[0026] The top of the feed cylinder 4 is fitted with a cover plate 502, and a cover door 503 is hinged to one side of the top of the cover plate 502. A drive motor 501 is fixedly connected to the top of the cover plate 502.

[0027] The output end of the drive motor 501 passes through the cover plate 502 and is fixedly connected to the drive rod 505. The bottom end of the drive rod 505 is fixedly connected to the first connecting plate 506 and the second connecting plate 705 respectively.

[0028] It should be noted that the output end of the drive motor 501 is set through the cover plate 502 and is mainly used to provide reciprocating driving force in the vertical direction. The lower end of the output shaft of the drive motor 501 is fixedly connected to the drive rod 505, which can efficiently transmit the rotation or up and down driving force of the motor to the lower structure. The bottom end of the drive rod 505 is fixedly connected to the first connecting plate 506 and the second connecting plate 705 respectively. The first connecting plate 506 is associated with the cleaning component, and the second connecting plate 705 cooperates with the anti-clogging component structure. Through this double-branch structure design, the drive rod 505 can synchronously drive the two structural units to move under the drive of the motor, thereby realizing the linkage control of the cleaning and anti-clogging functions inside the feed cylinder 4, and improving the overall operating efficiency and reliability of the device.

[0029] The bottom end of the limiting plate 508 is slidably connected to the top end of the first connecting plate 506, and the top end of the limiting plate 508 is slidably connected to the bottom end of the cover plate 502. A stabilizing plate 509 is fixedly connected between the top end of the first connecting plate 506 and the cover plate 502.

[0030] It should be noted that the bottom end of the limiting plate 508 is slidably connected to the top end of the first connecting plate 506, and the top end is slidably connected to the bottom end of the cover plate 502. This bidirectional sliding connection allows the limiting plate 508 to reciprocate vertically under the drive of the transmission structure. During the movement, the limiting plate 508 drives the cleaning brushes 504 and scrapers 507 on both sides to sweep and scrape along the inner wall of the feed cylinder 4, which can effectively clean the carbon black particles attached to the cylinder wall. To ensure the stability of the limiting plate 508 during the sliding process, a stabilizing plate 509 is set between the first connecting plate 506 and the cover plate 502. The stabilizing plate 509 plays a guiding and supporting role, preventing the limiting plate 508 from shifting or shaking during the movement, and ensuring the stability of the cleaning structure and the consistency of the cleaning effect.

[0031] The inner side of the stabilizing plate 509 is fixedly connected to the first reset spring rod 510, and the free end of the first reset spring rod 510 is fixedly connected to the inner side of the limiting plate 508. The outer side of the scraper 507 and the outer side of the cleaning brush 504 are both attached to the inner wall of the feed cylinder 4.

[0032] It should be noted that a first reset spring rod 510 is fixedly connected to the inner side of the stabilizing plate 509. The free end of the first reset spring rod 510 is connected to the inner side of the limiting plate 508, giving the limiting plate 508 an elastic reset function. When the drive motor 501 stops running or the direction of movement changes, the first reset spring rod 510 can automatically pull the limiting plate 508 back to its initial position under the elastic recovery action, ensuring that the cleaning brush 504 and the scraper 507 always remain in contact with the inner wall of the feeding cylinder 4, thereby achieving continuous and effective cleaning action. In addition, the outer sides of the cleaning brush 504 and the outer sides of the scraper 507 are both in contact with the inner wall of the feeding cylinder 4, ensuring that the bristles and the blade edge are always in full contact with the cylinder wall when the limiting plate 508 slides up and down. This not only removes powder residue but also scrapes off agglomerated particles or dried matter, further improving the cleanliness of the cylinder wall and preventing material accumulation that could cause blockage.

[0033] The technical effects achieved by the above embodiments are as follows: By setting an inner wall cleaning mechanism and an anti-blocking mechanism 7 on the top of the feeding device body 1, the problems of carbon black agglomeration, adhesion and poor feeding can be effectively solved. During operation, granulated carbon black is fed in by the feeding cylinder 4 at the top of the device. The cover plate 502 and the cover door 503 structure can be opened and closed conveniently, which facilitates feeding and sealing against dust. A drive motor 501 is provided on the top of the cover plate 502. The output end of the motor passes through the cover plate 502 and is fixedly connected to the drive rod 505. The bottom end of the drive rod 505 is connected to the first connecting plate 506 and the second connecting plate 705 in sequence to form a transmission drive structure. The top end of the first connecting plate 506 is slidably connected to the limiting plate 508. The inner walls of the limiting plate 508 are respectively provided with a cleaning brush 504 and a scraper 507, and a stabilizing plate 509 is provided between its bottom end and the cover plate 502. The limiting plate 508 is fixed by the first reset spring rod 510 fixed inside the stabilizing plate 509. The elastic reset function of the 8 means that the above structure, driven by the motor, can realize the periodic up and down movement of the limiting plate 508, which drives the cleaning brush 504 and the scraper 507 to scrape and clean the inner wall of the feeding cylinder 4, thereby removing the carbon black particles adhering to the inner wall and effectively avoiding blockage and pollution caused by the accumulation of residues. In addition, a separating screen 3 is connected in the middle of the feeding device body 1, which can separate agglomerated particles from smaller particles, which is beneficial to improving the uniformity of the feeding material and the subsequent granulation effect. The guide channel 2 is set on the front of the feeding device body 1, which helps to guide the particles to be discharged smoothly and reduce the retention rate. During the operation of the device, the cleaning brush 504 adheres to the inner wall of the feeding cylinder 4 for flexible cleaning, while the scraper 507 can strongly peel off the tightly adhered particles. The two work together to achieve multi-level and multi-angle cleaning, maintain the inner wall unobstructed and clean, and thus ensure the continuous and efficient feeding process. Example

[0034] like Figure 3 and Figure 4As shown, a feeding device for granulated carbon black includes all the contents of Example 1. In addition, a vertical plate 701 is fixedly connected to the top of the second connecting plate 705, a second reset spring rod 702 is fixedly connected to the inner side of the vertical plate 701, a rubber plate 703 is fixedly connected to the free end of the second reset spring rod 702, and a pre-extrusion block 704 is fixedly connected to the inner wall of the feeding cylinder 4.

[0035] The technical effects achieved by the above embodiments are as follows: The top of the second connecting plate 705 is fixedly connected to the vertical plate 701. The inner side of the vertical plate 701 is provided with a second reset spring rod 702. The free end of the spring rod is connected to a rubber plate 703. The rubber plate 703 is arranged opposite to the extrusion block 704 fixed on the inner wall of the feeding cylinder 4. This structure forms an adjustable pressing area during the feeding process. When the carbon black material is partially blocked or bridged, the rubber plate 703 will undergo elastic deformation under the extrusion of the material, forcing the carbon black material to redisperse and flow, thereby relieving the pressure of the blockage. At the same time, the second reset spring rod 702 can automatically reset the rubber plate 703 after the material pressure is released, ensuring structural stability and service life. The rigid design of the extrusion block 704 and the elastic design of the rubber plate 703 form a rigid-flexible flow-limiting channel, enabling the entire device to have a main The anti-clogging mechanism 7, when working in conjunction with the inner wall cleaning mechanism, can dynamically adjust the internal space and channel pressure distribution of the feed cylinder 4, improving the equipment's adaptability to carbon black in different particle states. In particular, when carbon black agglomerates due to moisture, compression, or electrostatic adsorption, the rubber plate 703 and the extrusion block 704 can apply a certain extrusion force to the material, causing it to slide back down, thus ensuring continuous feeding. At the same time, the reciprocating motion of the cleaning brush 504 and scraper 507 driven by the upper and lower drive limit plate 508 can further prevent local deposition of adhering substances, significantly improving the overall cleaning ability and adaptive anti-clogging capability of the device. In summary, the device can not only improve the feeding efficiency of granulated carbon black, but also has good cleanliness, safety, and operational stability, making it suitable for continuous and automated production needs.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
