Fig. 2 is the structure iron of bell base plate

Fig. 3 is a stove hearty cord composition

Vegetable fibre rod charring furnace comprises bell, body of heater, the stove heart etc.Bell 1 is tapered, comprise the conical surface 11, base plate 12 and chimney 13, it between the conical surface and base plate interlayer, few outer how staggered cigarette hole in having on the base plate 12, be distributed on three different radii circumference, the hole on each circumference is and is equally spaced, in order to the control gas stream in the stove, make furnace temperature uniform distribution from the inside to surface, the cigarette pore distribution is on the present embodiment base plate: 3,6,12.Add chimney and adopt the socket mode, be convenient to the unlatching of bell and close.Body of heater divides inside and outside two-layer, and the medullary ray of body of heater bottom fire door 11 and two big ventilation holes 12 is equilateral triangle and is symmetrically distributed, and makes wind-force more even.The fire bars of lighting a fire 10 is arranged in the stove above fire door 11, and the stove heart 3 and 10 centimeters the spacing of having an appointment between fire bars of lighting a fire are so that place kindling wood.Level is welded the waistband 6 of a hollow on body of heater shell above the fire door 11, and the inside and outside interlayer of waistband and body of heater constitutes air-return duct.Four ventilation holes 9 that are mutually 90 ° are arranged on the waistband district inner furnace body shell, a ventilation hole is arranged on the waistband 6, be positioned at the center in two ventilation for enclosures holes.Body of heater inner casing ventilation hole 7 is positioned at the top in ventilation for enclosures hole 9, is divided into four groups of 28 holes, and 7 ventilation holes are and are equally spaced in every group, and each organizes ventilation hole and the ventilation for enclosures hole is symmetrical distribution.Between the inside and outside layer of body of heater upper semisection two sealing-rings are arranged, last sealing-ring 2 is positioned at the body of heater upper end, and lower seal 8 is positioned at inner casing ventilation hole 7 tops, and filled heat insulating material 4 between the upper and lower sealing-ring, and thermometer hole 5 is positioned at the middle and lower part of body of heater upper semisection.The stove heart 3 is movable, is divided into upper and lower two-layerly, and the upper strata is to be three concentric(al) circless 31 that cross links to each other, lower floor is a fire bars 32, and is integrally welded with the column 33 of four upper end buckles between the upper and lower layer, both has been convenient to the stove heart and ventilated, make the interior charing of stove even, be convenient to lifting up into, hanging out of the stove heart again.

The vegetable fibre rod vertically is thrown in the stove heart 3, makes kindling wood, be put on the fire bars 10, with the igniting of adjustable pressure gasoline flamethrower with vegetable fibre bar waste material or firewood.Evenly igniting earlier, again the charged stove heart 3 is hung in body of heater, burn about 20～30 minutes (deciding) on envrionment temperature, promptly temperature reaches about 300 ℃ in stove, close fire door 11 and bottom two big ventilation holes 12, by furnace bosh ventilation hole natural ventilation charing.This moment, wind entered from the waistband hole, enter inside and outside shell interlayer air channel after four ventilation holes 9 on the shell heavily distribute more equably, through 28 ventilation holes 7 of inner casing, wind just enters in the stove equably again, guaranteed to set up horizontal uniform temperature field in the stove, made the interior charing of stove even, stable.After chimney becomes light blue blue or green cigarette by dense leucismus, continue charing 20～30 minutes, temperature reaches about 450 ℃ in the stove at this moment, from sealing the wind hole down, build stack cover, and all air-leak sections of stove are obturaged then with thickener, allow and close the fire cooling in the stove, treat that bell is chilled to room temperature and can goes out charcoal.

This vegetable fibre rod charring furnace, not electricity consumption fully, it is extremely low to consume energy, and every stove only needs 0.1～0.2kg gasoline igniting usefulness, and with 5～8kg left and right sides waste material or firewood, the stove that diameter is 1 meter just can be produced the artificial charcoal of 100～120kg in addition, and economic benefit is obvious.This furnace construction is reasonable, and is sturdy and durable, and temperature field in furnace is even, stable, so the charing yield rate reaches more than 90%, be fit to vast rural area and promote the use of, and production technique is simpler, is easy to grasp.
