Hot-air internal circulation type glass energy-saving furnace

Abstract

The invention discloses a hot-air internal circulation type glass energy-saving furnace. According to the invention, a plurality of sets of supporting columns are arranged at the lower end of a furnace body frame; a lower furnace main body is arranged on the furnace body frame; an access door is arranged on the lower furnace main body; a conveying frame is fixedly connected with and arranged on the lower furnace main body; a conveying mechanism is arranged in the conveying frame; a plurality of sets of conveying rollers are uniformly and rotatably connected with and arranged on the conveying frame; an upper furnace cover is fixedly connected with and arranged on the lower furnace main body through a connecting lock catch; a feeding inlet and a discharge outlet are respectively arranged attwo ends of the upper furnace cover; a partition frame is arranged in the upper furnace cover and divides the interior of the upper furnace cover into a heating bin and a cooling bin; the heating binis close to the feeding inlet; and an air blowing mechanism is arranged in the heating bin. The energy-saving furnace provided by the invention has good heat preservation effect, and the utilization rate of heat energy is increased through heat energy circulation in a furnace, so energy consumption needed by heating is reduced, and the cost of glass production is reduced.

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...
