Description

Technical Field

[0001] This utility model relates to the technical field of carbon black recycling equipment, specifically a carbon black recycling equipment for carbon black production. Background Technology

[0002] Carbon black is an amorphous carbon, a light, loose, and extremely fine black powder. The structure of carbon black is expressed as the degree to which carbon black particles aggregate into chains or grape-like structures. Carbon black composed of aggregates whose size, morphology, and number of particles per aggregate are considered high-structure carbon black. Existing carbon black re-blending equipment requires re-blending the produced carbon black because it contains carbon black of varying quality after production.

[0003] However, in the carbon black production process, qualified and unqualified carbon black products need to be mixed and dried with hot air to reduce the moisture content of the unqualified products. Traditional mixing devices are often simply designed, lacking sufficient mixing strength and uniformity, resulting in uneven carbon black mixing. This affects subsequent production processes and product quality. Furthermore, during carbon black production and re-blending, carbon black material easily adheres to the inner walls of storage tanks or drying processors. This adhered carbon black material is not only difficult to clean but also mixes into new material in subsequent production processes, leading to a decline in product quality. To address these problems, the inventors propose a carbon black re-blending device for carbon black production. Utility Model Content

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a carbon black recycling device for carbon black production, including a mixing tank 1. A stirring rod 2 is provided inside the mixing tank 1. Stirring blades 3 are fixedly connected to the outside of the stirring rod 2 at equal intervals. A U-shaped frame 4 is movably fitted inside the mixing tank 1 and on the outside of the top of the stirring rod 2. Stirring blades 5 are fixedly connected to both sides of the inner wall of the U-shaped frame 4 at equal intervals. The stirring blades 5 and stirring blades 3 are distributed alternately. An exhaust pipe 7 communicating with the inside of the mixing tank 1 is fixedly connected to the top of the mixing tank 1. Fan blades 8 are provided inside the exhaust pipe 7. A drive assembly 6 is provided at the middle of the top of the mixing tank 1.

[0021] The drive assembly 6 includes an L-shaped plate 61, which is fixedly connected to the top center of the mixing tank 1. A shaft coupling 62 is rotatably connected to the top of the inner wall of the L-shaped plate 61. A bevel gear 63 is fixedly connected to the outer side of the top of the shaft coupling 62. A rotating sleeve 64 is rotatably connected to the middle of the top of the mixing tank 1. The bottom end of the shaft coupling 62 moves through the rotating sleeve 64 and is fixedly connected to the top of the stirring rod 2. A bevel gear 65 is fixedly connected to the top of the rotating sleeve 64. A bevel gear 66 is rotatably connected to one side of the inner wall of the L-shaped plate 61. The bevel gear 66 meshes with the bevel gear 63 and the bevel gear 65 respectively. A servo motor 69 is fixedly installed on the top of the L-shaped plate 61. The drive end of the servo motor 69 is fixedly connected to the shaft coupling 62.

[0022] By adopting the above technical solution, the servo motor 69 drives the coupling 62 to rotate, which in turn drives the stirring rod 2, stirring blade 3 and bevel gear 63 to rotate, thus stirring the carbon black material inside the mixing tank 1. At the same time, the bevel gear 66 meshes with the bevel gear 63 and the bevel gear 65 respectively, driving the rotating sleeve 64, U-shaped frame 4 and stirring blade 5 to rotate in opposite directions. Furthermore, the cooperation between the stirring blade 5 and the stirring blade 3 ensures thorough stirring inside the mixing tank 1, further improving the drying efficiency.

[0023] A drive wheel 67 is fixedly connected to the outer side of the top of the rotating sleeve 64, and a driven wheel 68 is fixedly connected to the top of the rotating shaft of the fan blade 8. The outer sides of the drive wheel 67 and the driven wheel 68 are connected by belt drive.

[0024] By adopting the above technical solution, when the rotating sleeve 64 rotates, it drives the driving wheel 67 to rotate. The driving wheel 67 and the driven wheel 68 are connected by a belt drive, which drives the driven wheel 68 and the fan blade 8 to rotate. The fan blade 8 extracts the evaporated water from the carbon black material, accelerating the drying of the carbon black material. Furthermore, since the diameter of the driven wheel 68 is smaller than the diameter of the driving wheel 67, the transmission ratio between the driven wheel 68 and the stirring rod 2 is controlled, ensuring the stability of the equipment operation.

[0025] Scrapers 12 are fixedly connected to both sides of the U-shaped frame 4, and the scrapers 12 are in contact with the inner wall of the mixing tank 1.

[0026] By adopting the above technical solution and setting scraper 12, the scraper 12 can be rotated while the carbon black is being stirred, and the inside of the mixing tank 1 can be cleaned by scraper 12 to prevent the carbon black material from sticking to the inner wall of the mixing tank 1.

[0027] A filter screen 9 that communicates with the inside of the mixing tank 1 is fixedly connected to the top of the mixing tank 1 on the side away from the exhaust pipe 7. A discharge pipe 10 that communicates with the inside of the mixing tank 1 is fixedly connected to the bottom of the mixing tank 1. A switch valve is installed on the discharge pipe 10.

[0028] By adopting the above technical solution and setting the filter screen 9, it is convenient to add carbon black material into the mixing tank 1, and the processed material can be discharged through the discharge pipe 10 by opening the switch valve.

[0029] An observation window 11 is provided on one side of the mixing tank 1 to facilitate observation of the interior of the mixing tank 1.

[0030] By adopting the above technical solution and setting up the observation window 11, it is convenient to observe the internal condition of the mixing tank 1.

[0031] A filter screen 9 is fixedly installed on the inner side of the top of the exhaust pipe 7, and the rotating shaft of the fan blade 8 moves through the middle of the filter screen 9.

[0032] By adopting the above technical solution and setting up a filter screen 9, materials are prevented from being drawn out along with the exhaust pipe 7.

[0033] Working principle: When reprocessing carbon black, the carbon black material is added into the mixing tank 1 through the filter screen 9. Then, the servo motor 69 drives the shaft coupling 62 to rotate, which in turn drives the stirring rod 2, stirring blade 3 and bevel gear 63 to rotate, thus stirring the carbon black material inside the mixing tank 1. At the same time, bevel gear 66 meshes with bevel gear 63 and bevel gear 65 respectively, which drives the rotating sleeve 64, U-shaped frame 4 and stirring blade 5 to rotate in the opposite direction. The cooperation between stirring blade 5 and stirring blade 3 further stirs the inside of the mixing tank 1, thereby improving the drying efficiency.

[0034] Meanwhile, when the rotating sleeve 64 rotates, it drives the driving wheel 67 to rotate. The driving wheel 67 and the driven wheel 68 are connected by a belt drive, which drives the driven wheel 68 and the fan blade 8 to rotate. The fan blade 8 extracts the evaporated water from the carbon black material, accelerating the drying of the carbon black material. Furthermore, since the diameter of the driven wheel 68 is smaller than that of the driving wheel 67, the rotation ratio between the driven wheel 68 and the stirring rod 2 is controlled, ensuring the stability of the equipment operation.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
