Description

Technical Field

[0001] The invention belongs to the technical field of carbon black processing, in particular to a filtering device for carbon black production. Background Art

[0002] Carbon black is a light, loose and extremely fine black powder with amorphous carbon as the main component. Its specific surface area ranges widely from 10 to 3000 m² / g. It is a product generated by incomplete combustion or thermal decomposition of organic matter (such as natural gas, heavy oil, fuel oil, etc.) under insufficient air supply conditions, and has significant adhesion.

[0003] Carbon black has a wide range of applications and is an important industrial material. For example, it can be used as a black dye to make Chinese ink, printing ink and paint; in rubber products, it is widely used as a reinforcing agent to improve its strength and durability. In addition, carbon black also has important uses in many other industrial fields.

[0004] In some special fields, some carbon black with smaller particle size is usually used. The existing devices generally screen out particles with suitable particle size through a drum screen. In some existing technologies, the drum screen is often set with a higher and inclined feed port, which is conducive to the carbon black rolling along the drum wall under the action of gravity after feeding, so that the carbon black is evenly spread out. However, as the drum screen rotates, some carbon black particles with larger particle size that cannot be screened out will be deposited at the bottom of the drum screen. If too much is deposited, it is necessary to pause the device, remove it, re-grind it, and then screen it, resulting in low efficiency of the entire screening process.

An extension portion is provided at one end of the feeding hopper 207 connected to the drum screen 201, and the extension portion extends 2-8 cm into the drum screen 201. The provision of the feeding hopper 207 is helpful for feeding and guiding the angle of carbon black entering the drum screen 201, so as to achieve better dispersion and screening of carbon black.

[0030] Carbon black is thrown into one end of the drum screen 201, and the drum screen 201 is driven to rotate by the meshing of the screening gear 205 and the gear ring 208. The carbon black rolls and disperses on the inner wall of the drum screen 201, so that the carbon black of suitable particle size can be screened out through the mesh of the drum screen 201 and fall downward to the conveying device 206 for transfer.

[0031] The driving mechanism 3 includes a driving motor 301, a driving main shaft 302 and a first side bracket 306. The output end of the driving motor 301 is fixedly connected to a driving gear 303.

When the driving motor 301 is started, it can drive the driving gear 303 to rotate, and then transmit the action to the first driven gear 304 through the first chain 305. The first rotating shaft 204 is driven to rotate by the driving main shaft 302, thereby driving the screening gear 205 to rotate, and the drum screen 201 is driven to rotate by meshing with the gear ring 208.

The rod 404 is hinged, and the conveyor belt 405 is arranged under the conveyor device 206. The surface of the conveyor belt 405 is evenly spaced along the length direction. A plurality of one-way inclined teeth 407 with the same direction are arranged. The inclined surface of the one-way inclined teeth 407 is consistent with the pushing direction. One end of the second connecting rod 404 contacts the vertical surface of the one-way inclined teeth 407 and applies force to push the conveyor belt 405 to move around the two conveyor rollers 409. In the process of screening carbon black by the drum screen 201, some carbon black particles with a particle size larger than the screening mesh will move to the tail of the drum screen 201 to form an accumulation. By setting a The opening is set, and the carbon black particles that have not passed through the mesh screening can be discharged onto the conveyor belt 405. When the driving main shaft 302 drives the drum screen 201 to rotate, the worm 401 rotates synchronously, which can drive the worm wheel 402 to rotate. At the same time, the connection shaft 406 rotates to drive the first connecting rod 403 to rotate, and then drives the second connecting rod 404 to move. In this embodiment, the first connecting rod 403 and the second connecting rod 404 are regarded as a whole, and the state of the longest overall length is regarded as state 1, and the state of the shortest overall length is regarded as state 2. In the process from state 2 to state 1, the first connecting rod 403 is moved toward the drum screen 201. One side of the feed port of the drum screen 201 rotates, and one end of the second connecting rod 404 can push the conveyor belt 405 to move toward the feed port of the drum screen 201 through the upright surface of the one-way inclined tooth 407; in the process from state one to state two, the first connecting rod 403 rotates toward the side away from the feed port of the drum screen 201, and one end of the second connecting rod 404 can slide along the inclined surface of the one-way inclined tooth 407. The reciprocating motion between state one and state two realizes the intermittent advancement of carbon black, so that the carbon black can be pushed into the fine grinding mechanism 5 in piles on the conveyor belt 405, which helps to improve the fine grinding effect of carbon black particles.

[0033] The fine grinding mechanism 5 includes a fine grinding wheel 501, a grinding wheel groove 502, a fine grinding driving shaft 503 and a second side bracket 509. The fine grinding wheel 501 can be used in conjunction with the grinding wheel groove 502.

The other end of the inclined plate 508 is hinged with the pushing mechanism 4. The center of the fine grinding wheel 501 is fixedly connected with a grinding wheel driven shaft 504. The grinding wheel driven shaft 504 is fixedly connected to the grinding wheel driven shaft 504. A second driven gear 505 is fixedly sleeved, the fine grinding driving shaft 503 is connected to the end of the first rotating shaft 204 away from the driving mechanism 3, a driving gear 506 is fixedly sleeved on the fine grinding driving shaft 503, the second driven gear 505 and the driving gear 506 are meshed and connected through a second chain 507, the bottom of the second side bracket 509 is connected to the base 1, and the fine grinding driving shaft 503 and the grinding wheel driven shaft 504 are rotatably connected to the second side bracket 509;

[0034] The fine grinding wheel 501 is provided with a protrusion 511 in the circumference, and the protrusion 511 is slidably connected to the inner wall of the grinding wheel groove 502, and is used to scrape the carbon black out of the grinding wheel groove 502. The base 1 is provided with a receiving box 510 near the fine grinding wheel 501;

[0035] The fine grinding mechanism 5 can be indirectly driven by the driving mechanism 3 through the screening mechanism 2. When the first rotating shaft 204 of the screening mechanism 2 rotates, the action can be transmitted to the driving gear 506 through the fine grinding driving shaft 503, and then the second driven gear 505 is driven to rotate through the second chain 507, and then the fine grinding wheel 501 is driven to rotate through the grinding wheel driven shaft 504, so that the carbon black in the grinding wheel groove 502 is ground into smaller particles, and then when the protrusion 511 enters the grinding wheel groove 502 as the fine grinding wheel 501 rotates, the ground carbon black is scraped out and then thrown into the receiving box 510 by inertia.

[0036] See also Figure 1 , based on the above embodiment, another embodiment of the present invention further includes a tilt adjustment mechanism 6;

[0037] The tilt adjustment mechanism 6 includes a first universal joint 601, a second universal joint 602, and a cylinder 603. The two ends of the first universal joint 601 are respectively connected to the driving main shaft 302 and the first rotating shaft 204. The two ends of the second universal joint 602 are respectively connected to the first rotating shaft 204 and the fine grinding active shaft 503. The end of the first rotating shaft 204 connected to the fine grinding active shaft 503 has a telescopic structure. The cylinder 603 is fixedly mounted on the base 1.

The bottom of the support rod 604 is fixedly connected to the mounting seat 605, and the top of the support rod 604 is hinged to the support frame 202. By controlling the extension and contraction of the cylinder 603, the fine grinding mechanism 5 can be adjusted. The contraction drives the support rod 604 to rise and fall, and lifts up or lowers the support frame 202, and then controls the speed of carbon black screening and sliding in the drum screen 201 by adjusting the inclination angle of the drum screen 201. In order to stably achieve the inclination of the drum screen 201, a strip groove is provided at the hinge between the support frame 202 and the support rod 604. The strip groove allows the support rod 604 to be displaced from the hinge point of the support frame 202 during lifting and lowering. The telescopic structure at one end of the first rotating shaft 204 can allow the telescopic amount to change when the inclination angle of the support frame 202 changes. In this embodiment, the gear ratio set between each mechanism can just match the cycle of the pushing mechanism 4 completing one pushing and the fine grinding mechanism 5 completing one fine grinding.
