High pressure membrane anchor double uniform stream chilled glass furnace

Abstract

The invention belongs to the technical field of glass tempered equipment, and particularly discloses a high-pressure transmembrane double uniform flow tempered glass furnace. The furnace comprises a furnace body and a roller path formed by rotating rollers, wherein the roller path is positioned at a furnace door of an inner cavity of the furnace body, and a high-pressure transmembrane double uniform flow system is arranged above the roller path; and the high-pressure transmembrane double uniform flow system consists of a special level convection equation device, a first level convection equation device and a second level convection equation device which are orderly arranged in the inner cavity of the furnace body from top to bottom and connected with one another by circuits. The high-pressure transmembrane double uniform flow tempered glass furnace with novel heating mode provided by the invention has the advantages of high efficiency, energy conservation and environmental protection, and successfully meets the requirement of quick heating when the Low-E glass is tempered under the U value of between 0.02 and 0.08; and more importantly, the furnace eliminates the phenomena of falling slag and flying ash of heat insulation cotton for puzzling the industry for multiple years.

Description

technical field [0001] The invention belongs to the technical field of glass tempering equipment, and in particular relates to a high-pressure film-penetrating double-even-flow tempered glass furnace. Background technique [0002] At present, the heating of the tempered glass furnace mainly includes: radiation heating, conduction heating, forced convection, fan convection, and simple gas convection. Regardless of the structure or principle, it is impossible to fundamentally meet the tempering quality of low-emission Low-E glass, especially when the U value is 0.08-0.02. First, the power consumption of the hot air blower is too large, and the inertia of the fan blades is not easy. Precise control; second: the simple air flow blows the insulation cotton dust in the furnace, and the stainless steel oxidation points infiltrate too much into the Low-E glass coating layer; third: after long-term convection, the insulation cotton structure is loose, the density connection is poor, ...
