Abstract

The invention relates to a straight-through drying oven with an air curtain system. The straight-through drying oven comprises an inlet hood region, a fresh air curtain region, an inlet air curtain region, a preheating region, an internal air curtain region, a heating region, an outlet air curtain region, and an outlet hood region, wherein the regions are communicated with one another sequentially from front to rear. Each of the fresh air curtain region, the inlet air curtain region, the internal air curtain region and the outlet air curtain region is provided with an air curtain guide plate. Each air guide plate comprises a first angle plate and a second angle plate. A first top plate of the first angle plate and a second top plate of the second angle plate are both mounted a top wall plate of the drying oven. A gap between a first sloping plate of the first angle plate and a second sloping plate of the second angle plate forms an air passage. The air curtain guide plates in the inlet air curtain region and the outlet air curtain region prevent smoke inside the drying oven from overflowing. The air curtain guide plate in the internal air curtain region separates different temperature areas, so that temperature disturbance amongst different temperature areas is prevented effectively.

Description

technical field [0001] The invention relates to a straight-through drying furnace, in particular to a straight-through drying furnace with an air curtain system. Background technique [0002] In the straight-through drying furnace, the flue gas is easy to overflow at the entrance and exit of the drying furnace, which cannot meet the requirements of the working environment of the workshop; and inside the straight-through furnace, there is a problem of temperature shifting under the condition of different drying temperatures in two adjacent areas; Therefore, it is necessary to improve the existing straight-through drying furnace. Contents of the invention [0003] The object of the present invention is to address the above-mentioned defects and provide a straight-through drying furnace with an air curtain system that prevents the flue gas from overflowing and internal temperature shifting of the straight-through drying furnace. [0004] The technical solution adopted by the...
