In existing carbon black drying equipment, carbon black accumulates at the bottom of the drying drum due to its own weight, which prevents the hot air from being evenly distributed and causes uneven drying.
The drying device is equipped with a guide plate and a diversion channel. The guide plate disperses the carbon black granular material and the diversion channel evenly conveys it into the drying chamber. At the same time, a servo motor drives the drive rod and cam structure to make the screening screen move up and down, which, together with the hot air fan, achieves uniform drying and powder screening.
This method achieves uniform drying of carbon black granules and effective sieving of powder, thereby improving processing efficiency and drying effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon black processing technology, and specifically to a drying device for carbon black processing. Background Technology
[0002] Carbon black has a wide range of applications in the industrial field and is an important raw material for processing related equipment. Carbon black can be classified into conductive carbon black, special carbon black, soft carbon black, pigment carbon black, and hard carbon black, etc. Among them, pigment carbon black is used as a coloring pigment in inks, paints, coatings, and plastics. According to the coloring strength and particle size, it is generally divided into four types: high pigment carbon black, medium pigment carbon black, ordinary pigment carbon black, and low pigment carbon black. It is mainly produced by oil furnace method and tank method. Carbon black needs to be dried during the production process to obtain dry carbon black.
[0003] In the prior art, a Chinese patent document with publication number CN221425224U and publication date of July 26, 2024, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: A drying device for carbon black processing includes a drying barrel, a hopper, a pusher plate, a feeding box, a thermometer, an electrical control box, and a control panel. The hopper is fixed to the bottom end of the drying barrel, the pusher plate is installed at the bottom end of the hopper, the feeding box is located at the bottom end of the pusher plate, the thermometer is located at the right end of the hopper, the electrical control box is located at the right end of the drying barrel, and the control panel is located at the front end of the electrical control box.
[0004] To address the drying problem in carbon black processing, existing technology involves using a motor to drive a polished rod, causing the first dispersing rod and the rotating frame to rotate synchronously. As the rotating frame rotates, it drives the second dispersing rod to rotate along the inner wall of the drying drum. Through the cooperation between the first and second dispersing rods, hot air is blown up to disperse the carbon black. However, during this drying method, the carbon black tends to accumulate at the bottom of the drying drum due to its own weight, preventing the hot air from dispersing among the carbon black particles and resulting in uneven drying. Utility Model Content

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.
[0026] Example 1
[0027] like Figure 1-5 As shown, this utility model provides a drying device for carbon black processing, including a drying chamber 1. A top cover plate 2 is fixedly installed on the top of the drying chamber 1. A feed inlet 3 is fixedly installed on the top right side of the top cover plate 2. A discharge outlet 4 is opened on the bottom left side of the drying chamber 1. A diversion unit is provided at the bottom of the feed inlet 3. A drying unit is provided inside the drying chamber 1. The diversion unit includes a guide plate 31 fixedly installed at the bottom of the feed inlet 3. A diversion protrusion 32 is fixedly installed on the top of the guide plate 31.
[0028] Furthermore, the carbon black granules to be processed are introduced into the interior of the drying chamber 1 through the feed inlet 3. When the carbon black granules enter the interior of the feed inlet 3, they roll downward along the inclined angle of the guide plate 31. With the help of the diversion protrusions 32, the carbon black granules are dispersed and evenly flow into the diversion channel 33, which then transports them into the interior of the drying chamber 1.
[0029] Example 2
[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a diversion channel 33 is fixedly installed on the output end of the feed inlet 3, and the other end of the diversion channel 33 is fixedly installed at the top right through hole of the drying chamber 1. The drying unit includes a fixing block 11 fixedly installed on the inner walls of both sides of the drying chamber 1. A slide rod 12 is fixedly installed on both sides of the top of the fixing block 11. A screening screen plate 13 is slidably sleeved on the outer surface of the slide rod 12, and a return spring 14 is movably sleeved on the outer surface of the slide rod 12 below the screening screen plate 13. One end of the reset spring 14 is fixedly installed on the bottom end of the screening screen plate 13, and the other end of the reset spring 14 is fixedly installed on the top of the fixing block 11. A support bracket 15 is fixedly installed on the right outer surface of the drying chamber 1. A servo motor 16 is fixedly installed inside the support bracket 15. A drive rod 17 is fixedly installed on the output end of the servo motor 16. The other end of the drive rod 17 is rotatably installed on the left inner wall of the drying chamber 1. Cams 18 are fixedly sleeved on the outer surfaces of both ends of the drive rod 17. A roller 19 is rotatably installed inside the protruding end of the cam 18.
[0031] Furthermore, when the carbon black granules enter the drying chamber 1, they fall onto the top of the screening screen plate 13 and roll continuously towards the far end along the inclined angle of the screening screen plate 13, achieving uniform drying. The output end of the servo motor 16 drives the drive rod 17 to cause the two sets of cams 18 to rotate. When the cam 28 rotates, its protruding end will abut against and squeeze the screening screen plate 13, causing the screening screen plate 13 to slide down onto the outer surface of the slide rod 12 and squeeze the return spring 14. Then, the elastic reaction force of the return spring 14 will cause the screening screen plate 13 to spring back and reset, thereby making the screening screen plate 13 move up and down, which facilitates the screening of powder in the carbon black granules.
[0032] Example 3
[0033] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, a diversion box 22 is fixedly installed on the top of the upper cover plate 2, a diversion pipe 23 is fixedly installed on the output end of the diversion box 22, the other end of the diversion pipe 23 is fixedly installed inside the top of the upper cover plate 2, a hot air blower 21 is fixedly installed on the top of the diversion box 22, and the output end of the hot air blower 21 is fixedly installed inside the top of the diversion box 22.
[0034] Furthermore, by starting the hot air blower 21, hot air is discharged into the interior of the distribution box 22, and then the heat source inside the distribution box 22 is delivered to the interior of the drying box 1 through the distribution pipe 23 to dry the carbon black granular material inside the drying box 1.
[0035] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 16 and the hot air blower 21 through RS-485 communication. When it is necessary to start the servo motor 16 and the hot air blower 21, the PLC sends start commands to the servo motor 16 and the hot air blower 21 respectively, causing the servo motor 16 and the hot air blower 21 to start simultaneously.
[0036] The working principle of this drying device for carbon black processing will be explained in detail below.
[0037] like Figure 1-5As shown, during operation, the carbon black granules to be processed are introduced into the drying chamber 1 through the feed inlet 3. As the carbon black granules enter the feed inlet 3, they roll downwards along the inclined angle of the guide plate 31. The diverting strips 32 disperse the carbon black granules, causing them to flow evenly into the diverting channel 33. The diverting channel 33 then transports them into the drying chamber 1. At this point, the hot air blower 21 is activated, drawing hot air into the diverting box 22. The diverting pipes 23 then distribute the heat source from the diverting box 22 to the drying chamber 1, drying the carbon black granules inside. When the material enters the drying chamber 1, it falls onto the top of the screening screen plate 13 and rolls continuously towards the far end along the inclined angle of the screening screen plate 13, achieving uniform drying. At the same time, the output end of the servo motor 16 drives the drive rod 17 to cause the two sets of cams 18 to rotate. When the cam 28 rotates, its protruding end will abut against and squeeze the screening screen plate 13, causing the screening screen plate 13 to slide down on the outer surface of the slide rod 12 and squeeze the return spring 14. Then, the elastic reaction force of the return spring 14 causes the screening screen plate 13 to spring back and reset, thereby making the screening screen plate 13 move up and down, which facilitates the screening of powder in carbon black granular materials.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
