Problems solved by technology

The coal-fired furnace of the barn is built-in, using a three-stage baking process of yellowing, color fixing, and rib opening. During the baking process, the yellowing period is simmering and baking. The temperature and humidity cannot be effectively and timely controlled, which will have a certain impact on the quality of the cured tobacco leaves

Embodiment Construction

[0010] According to the accompanying drawings, the present invention includes a furnace 1, a furnace wall 28, an insulation layer 12, a grate 14 and a hot air duct 6. The furnace 1 is a furnace in which the volume of the furnace can be controlled by a furnace regulating plate 2, and the furnace regulating plate 2 is controllable. Move, the furnace adjustment plate 2 is connected to one end of the metal rod 5, the other end of the metal rod 5 is connected to the eccentric wheel 4, the eccentric wheel 4 is coaxially connected to the variable speed motor 19, and the eccentric wheel 4 and the variable speed motor 19 are installed at the lower part of the coal-fired furnace body . The upper part of the furnace body surrounded by the furnace regulating plate 2 is an inverted trapezoidal cone, and the lower part is a rectangular three-dimensional shape. A heat supply valve 7 is arranged at the outlet of the hot air passage 6, and the motor drives the heat supply valve shaft 9 to cont...

Abstract

The present invention relates to an automatic fire control coal-fired furnace of tobacco baking machine, including firing space, furnace wall, heat-insulating layer, fire grate and hot air duct, wherein the characterized in that: said firing space is surrounded by firing space adjusting plate and it has controllable variable capacity of firing space, the motion of firing space adjusting plate can be controlled for adjusting the fire to small, medium and big. One end of metal rod connect with firing space adjusting plate, and another end connect with eccentric wheel which connect with speed variable motor with same axle, eccentric wheel and speed variable motor are mounted lopsided downward of external coal-fired furnace. The present invention can greatly enhancing baking quality of tobacco, and it can guarantee the safety of burning in firing space and utilize sufficiently coal-fired heat energy through using naked fire baking and taking calorific radiation heat energy of firing space by circulating air duct, which not only can save coal by 20%, but also greatly enhance gradation rate of tobacco, therefore it can implement full-automatic and simply operation and liberate labor force.

Description

1. Technical field: [0001] The invention relates to a tobacco flue-curing device, in particular to a coal-fired stove with automatic fire control for the flue-cure tobacco machine. 2. Background technology: [0002] At present, most of the curing barns used in the production of flue-cured tobacco in China are naturally ventilated barns with rising air flow, and the fire control and ash removal are all controlled manually during the entire curing process. The coal-fired furnace of the barn is built-in, using a three-stage baking process of yellowing, color fixing, and rib opening. During the baking process, the yellowing period is simmering and baking. The temperature and humidity cannot be effectively and timely controlled, which will have a certain impact on the quality of the cured tobacco leaves. 3. Contents of the invention: [0003] The purpose of the present invention is to make up for the deficiencies of the furnace hearth in the prior art, and to design a fully au...
