Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1:

the embodiment provides an air heating furnace, which comprises a furnace body 1, wherein the inner cavity of the furnace body 1 comprises a coil area 10 and a heating area 11, and the coil area 10 is positioned above the heating area 11, as shown in fig. 1-3; an air inlet pipe 111 and a smoke exhaust pipe 112 are arranged on the side wall of the heating area 11, the air inlet pipe 111 is used for conveying combustible gas to the heating area 11, and the smoke exhaust pipe 112 is used for discharging impurities such as smoke generated by the combustible gas; at least one group of S-shaped pipelines 101 are arranged in the coil area 10, preferably two groups are arranged in the embodiment, each group of pipelines 101 is fixed on the side wall of the coil area 10 through a fixing frame 1011, the main purpose of the embodiment that the pipelines 101 are arranged into the S-shaped coil is to enable the S-shaped coil to be in contact with hot air in a larger area, the heating speed of the air in the pipelines 101 is increased, an inlet 102 and an outlet 103 of each pipeline 101 penetrate through the side wall of the coil area 10, a fan 1021 is connected at the inlet 102, and the air is conveyed into the pipelines 101 through the fan 1021; the coil area 10 and the heating area 11 are separated by a baffle 12, and the baffle 12 is provided with a plurality of sets of heat dissipation holes 121, in this embodiment, the baffle 12 may be a flat structure or an arch structure, in order to realize the aggregation of heat energy, preferably, the baffle 12 is composed of at least three sets of arch structures, and the heat dissipation holes 121 are disposed at the top of the arch structures, see fig. 4, further, in order to better heat the pipeline 101, preferably, the arching direction of the baffle 12 of the arch structure is perpendicular to the arrangement direction of the pipeline 101.
