A continuous vacuum glass preparing device and a preparing method

Abstract

A continuous vacuum glass preparing device is disclosed. The device includes a tunnel type kiln, and a plurality of mobile bearing gears corresponding to heating zones. Each bearing gear includes at least one bearing trolley. Each bearing trolley includes a frame the bottom of which is provided with idler wheels, a vacuumizing gear fixed to the frame, a heat-insulating bottom plate fixed to the upper part of the frame, and a vertical bearing support fixed to the heat-insulating bottom plate and used for supporting a glass assembly to be vacuumized. The heat-insulating bottom plates of a plurality of trolleys connected form a kiln bottom. A vertical fixing manner is adopted by the device, thus increasing the bearing capacity and increasing the production efficiency. During production, the glass assembly after powder distribution and support installation are finished is clamped tightly and then is conveyed in each heating zone by the bearing trolleys to achieve operation integrating heating, edge sealing and vacuumization, thus reducing a process of repeated heating, reducing energy consumption and reducing the processing cost.

Description

technical field [0001] The invention relates to the technical field of vacuum glass processing, in particular to a continuous vacuum glass preparation device and a preparation method. Background technique [0002] With the acceleration of urbanization, my country's building energy consumption will account for about 35% of the total energy consumption of the whole society, surpassing industrial energy consumption and becoming the largest field of energy consumption. Minimizing the reduction of building energy consumption has become an urgent problem in the field of construction. As an important part of the building envelope, doors and windows account for about 50% of the heat loss of the entire envelope. Therefore, high-performance doors and windows are a prerequisite for the realization of passive buildings. The selection, processing and installation quality of materials in doors and windows should be given highly valued. Glass accounts for about 70% of the outer window ar...

Problems solved by technology

[0003] However, the existing vacuum glass manufacturing process faces low efficiency, especially in the edge sealing and vacuuming stages, because of the long heat preservation time, long material loading time, and small processing quantity, etc., which become the bottleneck restricting the production
