Energy-saving glass annealing furnace

Abstract

The invention discloses an energy-saving glass annealing furnace which comprises an annealing furnace body (1). The annealing furnace body (1) is provided with three heating areas, namely a first heating area (2), a second heating area (3) and a third heating area (4); a small air blower (5) is arranged at an outlet of the annealing furnace body (1) and is connected with an air pipe (6) outside the annealing furnace body (1) and a frequency converter; the frequency converter is connected with a proportion integration differentiation (PID) controller. The small air blower is additionally arranged at the outlet of the annealing furnace body, and the air pipe is connected with the small air blower to blow cold air into the annealing furnace body so as to lower the speed of air flowing to the outlet in the annealing furnace body, so that heat loss of the annealing furnace is reduced, and the consumption of electric energy is saved; the operation frequency of the frequency converter is controlled through the PID controller, and the operating speed of the small air blower is further controlled, so that intelligent control is realized.

Description

technical field [0001] The invention relates to an energy-saving glass annealing furnace, which belongs to the field of glass processing. Background technique [0002] In glass bottle making enterprises, the annealing furnace generally adopts the electric heating type, which is a device that consumes more electric energy. The annealing furnace generally has three zones to automatically control the heating section, the first zone has the highest temperature, the second zone is the second, and the third zone is the lowest. After the molten glass is blown into shape by the line machine, it is sent to the annealing furnace through the conveyor belt for annealing. When the glass bottle enters the annealing furnace and runs from the high temperature area to the low temperature area, a large amount of heat will be taken away. When the directions are consistent, the annealing furnace will dissipate more heat, which will require more electric energy for heating, resulting in energy ...

After the molten glass is blown into shape by the line machine, it is sent to the annealing furnace through the conveyor belt for annealing. When the glass bottle enters the annealing furnace and runs from the high temperature area to the low temperature area, a large amount of heat will be taken away. When the directions are the same, the annealing furnace will dissipate more heat, which will require more electric energy for heating, resulting in energy waste
