Foam glass blank annealing device

Abstract

The method relates to the technical field of glass product annealing, and particularly discloses a foam glass blank annealing device. The device comprises a bottom plate, an electric motor, an annealing mechanism and a feeding mechanism, wherein the annealing mechanism comprises a screw cap, a heating device located in the spiral center of the screw cap and an exhaust fan; the screw cap is made ofa thermal insulation material and buckled on the bottom plate to form a closed spiral space with the bottom plate, air holes are formed in the side wall of a ring with the minimum diameter of the screw cap, a foam glass discharging port is formed in the end with the maximum diameter of the screw cap, and the exhaust fan faces the discharging port and acts on the inside of the screw cap; the feeding mechanism comprises a vertical telescopic cylinder, an output end of the vertical telescopic cylinder is connected with a feeding plate, and a push plate is glidingly connected onto the feeding plate; a feeding port matched with the feeding mechanism is formed in the bottom plate constituting the spiral space, and a wedge rod matched with the push plate is further arranged on the screw cap. With the adoption of the technical scheme, the problem of large space occupied by the conventional foam glass blank annealing device can be solved. Therefore, the device can be widely applied to foam glass annealing.

Description

technical field [0001] The invention relates to the technical field of annealing devices for glass products, in particular to an annealing device for foam glass blanks. Background technique [0002] Foam glass is a new type of inorganic thermal insulation material with glass as the main raw material and a uniform independent air gap structure. It completely retains the chemical stability of inorganic glass, and has the characteristics of low bulk density, small thermal conductivity, non-combustibility, and high mechanical strength. Cellular glass has good thermal insulation properties that will not deteriorate in a wide temperature range from ultra-low to high temperatures. During the production process of foam glass, the foam glass that reaches a high temperature of about 560 ° C must be gradually cooled to normal temperature in the kiln. The purpose is to eliminate the internal stress to the allowable range, so that the foam glass can obtain stable physical properties. a...
