Abstract

The invention relates to a tunnel furnace heat recycling device which comprises a shell. A heating device is arranged in the shell. An air induction device is arranged on the side of the heating device, a hot air outlet is formed below the air induction device, one side of the hot air outlet is provided with a first backflow hole, a first filter layer is arranged inside the shell, the first filterlayer separates the first side wall of the shell from the heating device, and a first heat recycling channel is formed between the first side wall and the first filter layer. By designing the tunnelfurnace heat recycling device, hot air left after the drying step is finished is recycled and heated again, the purpose of recycling heat exhausted by a tunnel furnace is achieved, and therefore energy waste is reduced.

Description

technical field [0001] The invention relates to a tunnel furnace, in particular to a tunnel furnace heat recovery device. Background technique [0002] The production of glass touch screens is mainly completed through a fully automatic touch panel production line. Since the touch panel manufacturing process includes a drying process for the touch panel, there is a special tunnel furnace on the automatic touch panel production line. Touch screen to dry. [0003] At present, the tunnel furnace installed on the automatic touch panel production line is basically not equipped with a heat recovery device or the heat recovery device is too simple, resulting in most of the heat discharged from the tunnel furnace directly flowing into the outside world, causing a lot of energy waste . Contents of the invention [0004] In view of the above technical problems, the present invention provides a tunnel furnace heat recovery device, which achieves the purpose of recycling the heat dis...
