Tabular corundum green pellet drying equipment and working method thereof

Abstract

The invention discloses tabular corundum green pellet drying equipment. The tabular corundum green pellet drying equipment comprises an air cylinder, a feeding port is formed in the left side of the air cylinder, an exhaust elbow is arranged on the right side of the air cylinder, a drying oven is arranged at the lower end of the exhaust elbow, a conical hopper is connected to the lower end of the drying oven, a discharging port is formed in the lower end of the conical hopper, the right end of the conical hopper is connected with a heating barrel, the upper end of the heating barrel is connected with an electric control box, the upper end of the electric control box is connected with a fan, the air cylinder is connected with a piston rod, the lower end of the piston rod is connected with a conical barrel, a movable groove is formed in the barrel wall of the conical barrel, a right-angle plate is arranged inside the movable groove, a hinge block is hinged to the upper end of the right-angle plate, and a material turning plate is fixed to the upper end of the hinge block. The tabular corundum green pellet drying equipment is reasonable in structural arrangement, green pellets can be evenly heated through the arrangement of the material turning device, and the drying efficiency and the drying quality are improved.

Description

technical field [0001] The invention relates to the related technical field of stone processing equipment, in particular to a plate-shaped corundum green ball drying equipment and a working method thereof. Background technique [0002] Tabular alumina is a pure sintered corundum without additives. It has a coarse crystal and well-developed α-Al2O3 crystal structure. The tabular corundum has a plate-like crystal structure under the electron microscope, with small pores and more closed pores. The porosity Roughly equivalent to fused corundum, it has high purity, good volume stability, and minimal reburning shrinkage. The refractory materials or castables used for production have good thermal shock stability and bending strength after high temperature treatment, while corundum production The required green balls are usually industrial alumina, which is made by grinding, forming, dehydration and drying. [0003] However, the existing green ball drying equipment generally puts t...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a plate-shaped corundum green ball drying equipment and its working method to solve the problem that the existing green ball drying equipment proposed in the above background technology usually puts green balls into the drying box, and directly In contact with raw balls, dry the moisture inside the green balls. Since the green balls are static during the drying process, they cannot be heated evenly, which leads to the problem of low drying efficiency and poor drying effect.
