Slit type baking house hot-air stove

Abstract

The invention relates to a crack type hot-blast stove for a curing barn, which relates to a drying apparatus, in particular to a drying hot-blast stove for the curing barn. The hot-blast stove is arranged inside a hot-blast heat exchange chamber on the end head of the curing barn and mainly comprises a chimney, an air duct, an inner cylinder, an outer cylinder, a feed opening and a fire grate, wherein the top of the outer cylinder is provided with a draught fan; the chimney is communicated with the upper part of the outer cylinder; the fire grate is positioned in the bottom center of the outer cylinder; and the feed opening is positioned on the lower part of the outer cylinder. The drying hot-blast stove for the curing barn is characterized in that the diameter of the outer cylinder is larger than that of the inner cylinder; an opening on the top of the inner cylinder is hermetically connected with the outer cylinder; a crack flushing flue is arranged between the outer circumference of the inner cylinder and the inner circumference of the outer cylinder; the end part of the inner cylinder which is hermetically connected with the outer cylinder is provided with a horizontal flue; the cylindrical wall of the inner cylinder is communicated with the cylindrical wall of the outer cylinder through a hot-blast tuyere; and the inside of the inner cylinder is provided with the air duct which is positioned under the draught fan. The drying hot-blast stove for the curing barn has a simple structure, good roasting quality and high thermal efficiency, is convenient to control, and can use fuel such as coal, lignite and straws.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying hot blast stove for a barn. Background technique [0002] Existing tobacco leaf baking is generally carried out by an oven. The oven has a simple structure. There is a hanger in the oven. The tobacco leaves are hung on the hanger and baked with coal fire. The flue at the bottom of the baking room naturally dissipates heat. , the thermal efficiency is low, and the quality of baking is not easy to control. The invention patent with the Chinese patent application number 200420089018.5 discloses a leaf roasting machine. The main parts of this leaf roasting machine are drying room, smoke exhaust outlet, hot blast stove, reversing device, upper air duct, lower air duct and smoke exhaust outlet. , the hot blast stove communicates with the reversing device, and the reversing device communicates with the drying room through the upper air channel and the lower air channel respectively. There is...
