Problems solved by technology

The structure of the air guide device of the traditional heating furnace is simple, the air volume is uneven, some parts have higher temperature, and some parts have lower temperature, it is difficult to achieve the furnace temperature uniformity required by the process in a short time, resulting in the heating of the material temperature is too high or too low
Therefore, the temperature uniformity of the low-temperature furnace has always been a difficult point.

Abstract

The invention provides a low-temperature furnace hot air circulation system and method. The system comprises a fan and an air guide device, wherein the fan is a centrifugal fan, the fan is arranged atthe top of a heating furnace and embedded into the furnace, the air guide device is arranged in the furnace, the air guide device is arranged below an impeller of the fan, the air guide device comprises a top plate, two opposite side plates and a bottom plate, the tops of the two side plates are connected with the top plate, the bottoms of the two side plates are connected with the bottom plate,a fan opening is formed on the top plate, a first air guide structure and an air blocking device are arranged on the side plates, the first air guide structure is close to a front furnace opening of the heating furnace, and a second air guide structure is arranged on the bottom plate. The system is advantaged in that air inlets of different sizes are formed in different positions such as the top,two sides and the bottom of the air guide device, the air volume and air pressure entering a furnace cavity from each air outlet are uniform, the hot air is uniformly circulated in the furnace cavity,so the furnace temperature uniformity is ensured, the heating and heat preservation time is shortened, energy consumption is reduced, production efficiency of the whole production line is improved, and productivity is increased.

Description

technical field [0001] The invention belongs to the technical field of low-temperature furnaces, and in particular relates to a hot air circulation system and method for low-temperature furnaces. Background technique [0002] For the heating furnace with relatively low heating temperature, the internal gas circulation is very important, so the structure of the air guide hood is particularly important. The structure of the air guide device of the traditional heating furnace is simple, the air volume is uneven, some parts have higher temperature, and some parts have lower temperature, it is difficult to achieve the furnace temperature uniformity required by the process in a short time, resulting in the heating of the material The temperature is too high or too low. Therefore, the furnace temperature uniformity of the low temperature furnace has always been a difficult point. Contents of the invention [0003] The purpose of the present invention is to provide a low-tempera...
