Vacuum sintering furnace for manufacturing vacuum glass

Abstract

The invention relates to a vacuum sintering furnace for manufacturing vacuum glass, which comprises a vacuum set, a high temperature-resistant fan and a vacuum sintering furnace, wherein the vacuum set and the high temperature-resistant fan are arranged outside the vacuum sintering furnace, the vacuum set is communicated with the inner part of the vacuum sintering furnace by a vacuum pipeline, the high temperature-resistant fan is communicated with the inner part of the vacuum sintering furnace by a wind inlet pipe and a wind outlet pipe respectively, in the vacuum sintering furnace, wind inlet rack pipes communicated with the wind inlet pipe of the high temperature-resistant fan are evenly arranged on the inner wall of a furnace body at intervals, wind outlet rack pipes communicated with the wind outlet pipe of the high temperature-resistant fan are evenly arranged on the upper wall or / and the lower wall in the furnace body at intervals, and a furnace internal / external closed cycle is formed by the wind inlet pipe and the wind outlet pipe through the high temperature-resistant fan. The vacuum sintering furnace is low in cost price, a sealing side can be heated under normal pressure, the problem of the air leakage of the sealing side caused by a mass of air bubbles of glass powder caused by heating under a vacuum state in the furnace is solved, the quality of the vacuum glass is effectively improved, the low-pressure vacuumizing and sealing mode is particularly suitable for the manufacture of the plate vacuum glass, and the vacuum sintering furnace is small in volume and low in energy consumption.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a vacuum sintering furnace for manufacturing vacuum glass. Background technique [0002] The traditional flat vacuum glass is made by heating molten powder in a vacuum state in a vacuum sintering furnace. The vacuum sintering furnace is a closed structure except for the furnace door. The balance of the temperature in the furnace needs to be stirred by multiple sealed axial flow fans on the furnace top. The air in the furnace is obtained, and the furnace is heated in a vacuum state. The furnace type is a multi-purpose comprehensive furnace type. As far as vacuum glass manufacturing is concerned, the above-mentioned vacuum sintering furnaces are relatively expensive, and the preparation process is relatively complicated. The resulting vacuum glass products are of poor quality, consume more energy, and have low temperature regulation efficiency. Contents of the invention [0003] The ...
