Technical Field

[0001] The utility model relates to the technical field of carbon black granulation processing, in particular to a fine screening device for carbon black granulation processing. Background Art

[0002] The fine screening device for carbon black granulation processing is a device used to separate carbon black particles. In the process of carbon black preparation, carbon black usually exists in the form of powder or granules, and the fine screening device is used to screen the carbon black particles according to their size, so as to obtain the required particle size range in the production process. This device usually includes components such as screens, vibration devices and silos. Through the action of vibration and screens, carbon black particles can be separated according to their size, thereby achieving a fine screening effect. This device plays an important role in the carbon black production process and can improve product quality and production efficiency.

[0003] There are many existing technologies for fine screening devices for carbon black pelletizing, such as:

This device can improve the work efficiency of replacing the mesh cage, does not require the cooperation of multiple people, and can avoid accidental injury to workers.

[0005] Most of the fine screening devices used in carbon black granulation processing include a screening device, through which the float carbon black is screened, but carbon black usually exists in the form of powder or particles, which means that there is often carbon black powder on the surface of the carbon black particles, and the carbon black powder may adhere to the surface of the carbon black particles, so that the actual size of the carbon black particles increases, which may cause the screening device to be unable to accurately separate the carbon black particles according to their actual size, thereby affecting the screening accuracy. In addition, the powder forms a layer of covering on the surface of the carbon black particles, which may increase the adhesion between the particles, making it more difficult to separate the particles, which may cause particles to accumulate or block the screen holes during the screening process, thereby reducing the screening efficiency.

[0006] In view of this, we propose a fine screening device for carbon black pelletizing processing. Utility Model Content

[0023] Most of the fine screening devices used in carbon black granulation processing include a screening device, through which the float carbon black is screened, but carbon black usually exists in the form of powder or particles, which means that there is often carbon black powder on the surface of the carbon black particles, and the carbon black powder may adhere to the surface of the carbon black particles, so that the actual size of the carbon black particles increases, which may cause the screening device to be unable to accurately separate the carbon black particles according to their actual size, thereby affecting the screening accuracy. In addition, the powder forms a layer of covering on the surface of the carbon black particles, which may increase the adhesion between the particles, making it more difficult to separate the particles, which may cause particles to accumulate or block the screen holes during the screening process, thereby reducing the screening efficiency.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a fine screening device for carbon black granulation processing, including a vibrating screening group 100 and a transport group 200, the transport group 200 includes a tube body 201, a feed port 202 is provided on one side of the tube body 201, and a discharge port 203 is provided on the other side of the tube body 201. In consideration of transporting carbon black particles while avoiding accumulation of carbon black particles, a keel 211 is provided in the tube body 201, and a driving group 210 is provided at one end of the tube body 201 close to the feed port 202. The driving group 210 is used to drive the keel 211 to rotate. In consideration of powder removal, an air supply group 220 is provided at one end of the tube body 201 close to the discharge port 203. The air supply group 220 is used to blow air to the keel 211.

[0025] The improvement of this embodiment lies in that a keel 211 is provided in the tube body 201, and the keel 211 is driven to rotate by the driving group 210, so as to drive the carbon black to move forward. At the same time, the advancing carbon black is always in a rotating and falling state, so as to prepare for the next step of powder removal. An air supply group 220 is provided on one side of the tube body 201, and the wind force generated by the air supply group 220 is used to remove the powder from the moving carbon black, so as to reduce the influence of the powder on the carbon black particles.

[0026] Considering the introduction of the air supply group 220 and the driving group 210 and avoiding the accumulation of powder in the tube body 201, the second embodiment of the present utility model is shown.

[0027] The air supply group 220 includes a bracket 221, a fan blade 222 is provided on one side of the bracket 221, and a motor for driving the fan blade 222 to rotate is provided on the other side of the bracket 221. When the motor is started, the motor output shaft rotates, driving the fan blade 222 fixed to the motor output shaft to rotate, thereby generating wind force. The driving group 210 includes a dust collecting chamber 213, a motor is provided in the dust collecting chamber 213, and the output shaft of the motor in the dust collecting chamber 213 is fixed to one side of the keel 211. When the motor is started, the motor output shaft rotates, driving the keel 211 fixed to the motor output shaft to rotate, thereby driving the carbon black particles on the keel 211 to move forward. A plurality of filter screens 212 are provided on one side of the dust collecting chamber 213 to facilitate the discharge of powder from the tube body 201 into the dust collecting chamber 213 through the filter screens 212. A powder outlet 214 is provided at the bottom of the dust collecting chamber 213.

[0028] In summary, the working principle of this solution is as follows:

[0029] The carbon black particles are put into the feed port 202 through the tube body 201, and the feed port 202 is covered with a cover plate. The motor is started, and the motor output shaft rotates, driving the keel 211 fixed to the motor output shaft to rotate, thereby driving the carbon black particles on the keel 211 to move forward and move. The other motor output shaft rotates, driving the fan blades 222 fixed to the motor output shaft to rotate, generating wind force, thereby removing powder from the carbon black particles in the keel 211. The removed powder is discharged from the tube body 201 into the dust collecting chamber 213 through the filter screen 212, and is discharged from the powder outlet 214 set at the bottom of the dust collecting chamber 213. As the keel 211 rotates, the carbon black particles are discharged from the outlet 203 of the tube body 201, and directly fall into the vibration screening group 100 for vibration grading and screening.
