Drying device roller for producing carbon black

Abstract

The invention discloses a drying device roller for producing carbon black. A plurality of arc-shaped heat conduction plates are evenly distributed on the inner wall of the roller in parallel and inclined by 45 degrees, a blocking piece is arranged on one side of each arc-shaped heat conduction plate to form a whole with the arc-shaped heat conduction plates, the lengths of the arc-shaped heat conduction plates evenly distributed in the roller are sequentially reduced from a smoke inlet to a smoke outlet, therefore, a section is formed, the ends of the arc-shaped heat conduction plates are connected to form an equilateral parallelogram, the other end parts of the arc-shaped heat conduction plates are connected with a heating rod, and the heating rod is arranged on the outer wall of the roller. The roller has the advantages that the contact area of the carbon black and the arc-shaped heat conduction plates can be increased through the length change of the arc-shaped heat conduction plates, the drying time of the carbon black to be dried in the roller can be prolonged, the carbon black can move disorderly to the greatest extent by utilizing the reverse rotation of the roller and the action of the blocking piece, and non-uniform drying of the carbon black in the center of the roller is prevented.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device cylinder for producing carbon black. Background technique [0002] In the production of carbon black, the raw material oil is cracked at high temperature to generate carbon black flue gas, which is granulated by a granulator, and then dried in a dryer to form finished carbon black. At present, the carbon black dryer adopts a drum structure, and inside the drum is For the carbon black to be dried, a heat shield is installed on the outside of the drum, and several combustion ports are uniformly arranged at the bottom between the drum and the heat shield, and the drum is continuously heated through the combustion ports, so as to achieve the purpose of drying the carbon black, but Due to the large inner diameter of the drum of the current dryer, the inner diameter reaches 2-3 meters, and the length reaches more than 10 meters. The carbon black is heated unevenly in the drum. It is n...
