An infrared heating device

Abstract

The invention provides an infrared heating device. The infrared heating device comprises a fan, an air pipe arranged on the fan, an air guiding cylinder arranged at the air outlet of the air pipe and a baffle plate arranged at the air outlet of the air guiding cylinder, wherein the air pipe and the air guiding cylinder are communicated, a rectifying grid is arranged inside the air pipe, a plurality of through holes are formed in the baffle plate, and a plurality of infrared heating pipes are arranged in front of the baffle plate. When the infrared heating device provided by the invention is used, the air produced by the fan passes through the rectifying grid, then smoothly enters the air guiding cylinder, then uniformly passes through the through holes in the baffle plate, flows through the infrared heating pipes and arrives at a heating surface. The infrared heating device provided by the invention has the advantages that two ways, namely thermal radiation and thermal convection, are adopted for heating, the heating efficiency is improved, and the surface of a to-be-heated solid is uniformly heated, so that product quality is guaranteed.

Background technique [0002] Infrared heating technology is widely used in all walks of life. Because of its advantages of fast heating speed and low energy consumption, it is currently favored by people in textile, leather and metal heat treatment. However, this technology is still immature in the glass processing industry. For example, during the curing process of photovoltaic glass coating and the tempering process of glass, high temperature treatment is required for the coating layer.

Problems solved by technology

However, this technology is still immature in the glass processing industry. For example, during the curing process of photovoltaic glass coating and the tempering process of glass, high temperature treatment is required for the coating layer.

[0003] At present, in the curing process of the coating layer of photovoltaic glass and the tempering process of photovoltaic glass, heat conduction through heating wire is the most used method. Although this method can meet the heating requirements, the heat conduction speed is slow and the energy consumption is high. High; of course, some people try to use infrared heating. The method is to install an infrared heating tube in the heating furnace and use its thermal radiation for heating, but it cannot solve the problem that the glass bursts in the furnace and damages the infrared heating tube.

The above two methods still have common defects, that is, the heating efficiency is low, and the temperature of the heating surface is uneven during the heating process, which may easily lead to deformation or even cracking of the heating surface.
