Automatic stoking system and device for tobacco leaf bulk curing barn

Abstract

The invention discloses an automatic stoking device for a tobacco leaf bulk curing barn. The automatic stoking device comprises a curing barn, a heat supply system, a grate, an air chamber, a stokinghopper, a coal conveying sleeve, a coal conveying reel and a coal conveying motor, wherein the heat supply system is arranged in the curing barn; the air chamber is arranged under the grate; the stoking hopper is externally arranged outside the curing barn; the coal conveying sleeve is connected to the grate and is arranged at the bottom of the stoking hopper; the coal conveying reel is arranged in the coal conveying sleeve and extends to the grate; the coal conveying motor is arranged on the outer end part of the coal conveying reel; the bottom of the air chamber is connected to a combustionfan arranged outside the curing barn through an air supply pipe; and an automatic control instrument is connected to the coal conveying motor and accesses a temperature sensing signal on the heat supply system. When temperature reduction in the curing barn occurs, the automatic control instrument automatically turns on the coal conveying motor; the coal reel conveys coal blocks in the stoking hopper into the grate to be combusted according to the quantity and the speed; after the temperature reaches a stable value, the stoking is stopped, so that the automatic stoking control is realized; themanual supervision and manual stoking are avoided; more precise control can be realized on the stoking quantity; the temperature control precision of the curing barn is ensured; and the curing qualityof flue-cured tobacco is improved.

Description

technical field [0001] The invention relates to the technical field of equipment related to a dense curing room for curing tobacco leaves, in particular to an automatic coaling system and device for a dense curing room for tobacco leaves. Background technique [0002] Tobacco leaf intensive curing room is a special equipment for processing tobacco leaves in the tobacco industry. The basic structure includes a smoke chamber and a hot air chamber. The main equipment includes heating equipment, ventilation and humidity removal equipment, and temperature control equipment. It is more than twice that of forced ventilation, hot air circulation, with temperature and humidity detection. According to the airflow mode, it is divided into airflow ascending type and airflow descending type. It is a common equipment for farmers to process flue-cured tobacco. [0003] At present, farmers need to conduct regular inspections on the real-time temperature of the curing barn during the flue-cu...
