Hot gas circulating system for drying room

Abstract

The invention discloses a hot gas recycle system for drying room, which comprises a room and a boiler arranged in the room. A chimney and a boiler air inlet communicated with the outside world are separately arranged on the boiler. The invention is characterized in that: a hot house composed of inner clapboards is arranged in the room; a channel and a hot-air chamber are arranged between the inner clapboard and the room; the boiler is arranged in the hot-air chamber; an exhaust fan is arranged between the channel and the hot-air chamber and is also arranged over the boiler; a wind board is arranged on one side of the inner clapboard near the boiler and an exhaust inlet opposite to the wind board is arranged on the other side of the inner clapboard; the exhaust inlet is communicated with the exhaust fan by the channel. The invention has the advantage that: after being blown in the hot house via the wind board, the hot air emitted by heating boiler goes out from the exhaust inlet on the other side of the hot house and form a hot-air circulating system through the exhaust fan to thoroughly dry the materials in the hot house with good drying quality.

Description

technical field [0001] The invention relates to a drying room, in particular to a hot air circulation system for the drying room. Background technique [0002] Many materials have to be dried in the drying room before use, and the method of drying the materials is generally to place the materials in the drying room, and then send hot air into the drying room through boiler heating to dry the materials. However, many drying rooms generally have only one vent, and the airflow enters and exits through the same vent. The effect of air circulation in the drying room is poor, and the temperature is uneven. The temperature near the vent is high, and the place far away from the vent The temperature is low, the drying quality of the material is poor, and the drying time is long. If you want to improve the drying quality, you can only adjust the position of the feeding tray or the feeding cart frequently, which is troublesome and requires a lot of work.
