A hot air internal circulation glass energy-saving furnace

Abstract

The invention discloses a hot air internal circulation type glass energy-saving furnace. Several groups of support legs are arranged at the lower end of the furnace body frame, the lower furnace body is arranged on the furnace body frame, and the lower furnace body is provided with maintenance The conveying frame is fixedly connected to the main body of the lower furnace, and a conveying mechanism is arranged inside the conveying frame, and several groups of conveying rollers are uniformly rotated and connected to the conveying frame; the upper furnace cover passes through the connecting lock The buckle is fixedly connected to the main body of the lower furnace, the two ends of the upper furnace cover are respectively provided with a feed port and a discharge port, and a barrier frame is arranged in the upper furnace cover, and the barrier frame connects the upper furnace cover The interior of the furnace cover is divided into a heating chamber and a cooling chamber. The heating chamber is close to the feeding port, and an air blowing mechanism is arranged in the heating chamber; Utilization efficiency, thereby reducing the energy loss required for heating and reducing glass production costs.

Description

technical field [0001] The invention relates to the technical field of glass tempering furnaces, in particular to a hot air internal circulation type energy-saving glass furnace. Background technique [0002] The process of the physical tempering furnace is to heat the glass to a certain temperature, and then cool it rapidly to increase the mechanical properties and thermal stability of the glass. However, the existing glass tempering furnace is heated and cooled separately, which is easy to cause glass damage during the transfer process. In the process of heating or cooling, the upper and lower surfaces of the glass are heated unevenly, which will easily lead to poor glass tempering effect and affect the tempering strength of the glass, and the heating furnace body of the glass tempering furnace has poor heat preservation effect, and the energy consumption required for heating is large. , which leads to the problem of increased glass production costs. [0003] The patent w...
