Description

Technical Field

[0001] This utility model relates to the field of carbon black processing technology, and specifically to a screening device for carbon black processing. Background Technology

[0002] Carbon black is an amorphous carbon, a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. During the carbon black processing, carbon black needs to be screened to facilitate its classification.

[0003] In the prior art, patent document CN217550455U discloses a carbon black powder screening device, including a horizontal airflow screen. The horizontal airflow screen includes a screen box, a rear end cover, and a clamping plate. The screen box and the rear end cover are detachably connected. It also includes a drive mechanism for driving the detached rear end cover along the length of the screen box away from or towards it. The rear end cover and the clamping plate are connected, and the end of the cylindrical mesh cage inside the screen box is coaxially provided with a first annular end plate. The two sides of the first annular end plate respectively abut against the clamping plate and the annular partition inside the screen box. The clamping plate has through holes. The gap between the rear end cover and the clamping plate, and the through holes, constitute a material channel for coarse material in the inner cavity of the cylindrical mesh cage to flow into the screen box. This device can improve the efficiency of changing the mesh cage, eliminates the need for multiple people to work together, and avoids accidental injury to workers.

[0004] To address the issue of inconvenient filter replacement in existing screening devices, current technology employs a drive mechanism to move the rear cover and pressure plate away from the screen box, thereby releasing the restriction on the cylindrical mesh cage inserted into the screen box. However, this method still results in the device being inconvenient to crush carbon black during use, easily causing carbon black agglomeration, which reduces the practicality of the screening device.
