Embodiment Construction
[0026] Such as Figure 1-Figure 7 The shown biomass hot air flue-cured tobacco furnace includes a furnace body 1 and a furnace 2 and a slag chamber 3 on the furnace body 1, a furnace bar 7 is arranged between the furnace 2 and the slag chamber 3, and a charging door is provided on the front wall of the furnace 2 4. It is easy to open and close and add firewood, which can prevent the flames from escaping and heat loss; the front wall of the slag chamber 3 is provided with a slag removal door 6, which is convenient for removing ash and slag, and can be closed in time to prevent heat loss, clean and hygienic. The heat collection chamber 10 and the lower heat storage chamber 12 are separated by a partition 33 right above the furnace 2 . A burner 9 is horizontally arranged in the furnace 2, and the burner 9 includes a box-type air duct 91 and a row of air distribution holes 92 provided on the rear side of the box-type air duct 91 to provide sufficient oxygen to the hot air to accel...

The invention discloses a biomass hot air tobacco roasting furnace. A burner is arranged in a hearth, a heat collection channel is reserved between the burner and the rear wall surface of the hearth, a heat collection chamber and a lower heat storage chamber are partitioned by a partition plate above the hearth, and the heat collection channel is communicated with the heat collection chamber; and the upper part of the heat collection chamber is communicated with an initial radiating tube bank, the upper end of the initial radiating tube bank is communicated with an upper heat storage chamber, a transitional radiating tube bank is communicated below the upper heat storage chamber, the lower end of the transitional radiating tube bank is communicated with the lower heat storage chamber, an afterheat radiating tube bank which is adjacent to the transitional radiating tube bank is communicated above the lower heat storage chamber, and the upper end of the afterheat radiating tube bank is communicated with a smoke collection chamber which is provided with a chimney. The heat is transferred to the external world through the heat collection chamber, the upper heat storage chamber, the lower heat storage chamber, the smoke collection chamber, the initial radiating tube bank, the transitional radiating tube bank and the afterheat radiating tube bank in the transmission process, so that a radiating channel in the form of rotation is formed; the combustion efficiency is high; the heat dissipation effect and the heat utilization rate can be greatly improved; and the tobacco roasting furnace is environment-friendly and energy-saving.
Description
technical field [0001] The invention belongs to the technical field of flue-cured tobacco equipment, in particular to a biomass hot air flue-cured tobacco furnace. Background technique [0002] After the tobacco leaves are harvested, the tobacco leaves must first be dried. Tobacco leaves are dried by heating and drying. The heat sources include sunlight, stove, electric heating, etc. Among them, the drying method using a stove as a heat source is more common. Stove flue-curing is to install a heat exchange room on one side of the flue-curing room. The stove is located in the heat-exchange room. A hot air fan is installed between the heat-exchange room and the flue-curing room. The hot air blower blows the heat emitted by the stove into the flue-curing room to dry the tobacco leaves. Provide hot air. Stoves are generally composed of hearth, grate, slag chamber and chimney, etc., which have low combustion efficiency, poor heat dissipation effect, and serious heat loss. Under...
