Screening device for white carbon black production

Abstract

The invention discloses a screening device for white carbon black production. The screening device comprises a screen drum, a first supporting frame, a second supporting frame, a material receiving box and a base. A feed hopper box is arranged at the upper end of the screen drum. A first rotating shaft is arranged inside the screen drum. A screw blade is arranged on the first rotating shaft. One end of the first rotating shaft is connected with a first rotating motor. A second rotating shaft is arranged at the left side of the screen drum. A second rotating motor is arranged at the other end of the second rotating shaft. A discharging outlet is formed in the outer wall of the bottom of the screen drum. Springs are arranged inside both the first supporting frame and the second supporting frame. Vibration motors are arranged outside both the first supporting frame and the second supporting frame. The first supporting frame and the second supporting frame are vertically arranged on the base. The base is provided with universal wheels. The material receiving box is arranged at the upper side of the base. The screening device for white carbon black production provided by the invention is simple in structure, stable in work, good in dynamic equilibrium and high in safety.

Description

Technical field [0001] The invention relates to the field of screening, in particular to a screening device for the production of white carbon black. Background technique [0002] At present, in the screening and grading of raw materials and finished products in grain, food, feed and other industries, cyclotron screening devices are widely used, such as the "plane cyclone screen" disclosed in Chinese Patent Document CN202356294U (announcement date is August 1, 2012). It includes a base and a screen body. The two ends of the base are respectively provided with gantry hangers. The two gantry hangers and the hanging rings of the base are respectively connected with a hoisting rope for horizontally hoisting the base, and one end of the base is installed The driving device is connected to one end of the screen body through an eccentric block transmission, and the other end of the screen body is inclined downward and hung on the gantry hanger at the corresponding end by a sling. In th...

AI Technical Summary

Problems solved by technology

However, during the entire screening process, part of the weight of the material and the sieve body acts on the sling, so that the sling bears a large load, especially in the process of screening, the tensile load borne by the sling will be will be larger, which will lead to aggravated fatigue damage of the sling and affect the working stability of the entire rotary screening device

At the same time, affected by the horizontal relative movement of the screen body and the gantry hanger, shear damage will occur on the connecting parts connecting the gantry hanger and the screen body at both ends of the hanging rope, so that the reliability and stability of the hanging rope connecting the gantry hanger and the screen body are affected. Influence, reduce the use safety and stability of the whole rotary screening device
