Abstract
The utility model relates to a downward air-heating coal furnace, which essentially consists of a jacketed stove body, a blast room, a flue pipe, a coal feeding opening, a taphole and a sirocco conveying system. The iron panel on the blast room where is provided with an internal sleeve of the jacketed stove body is provided with a plurality of vents, and the circumference is provided with a plurality of strip upright air inlet pipes. Therefore, the coal in the jacketed stove body can gain sufficient air, and reach an absolute burning effect, the thermal efficiency is improved and the energy resource is saved.
Description
The utility model relates to a kind of stove and accessory, specifically is a kind of coal-fired counter-burning type heating oven dry hot-blast stove.
At present, the oven dry that is used to warm oneself stove and accessory, mainly by the jacket type body of heater, compositions such as blast chamber and hot blast induction system, during operation, the burning of the fire coal in the jacket type body of heater is with the air heat in the chuck, then, hot blast is blown out, use for the heating oven dry by hot air blower.This jacket type body of heater is the column type cylindrical shell, and certain altitude is arranged, and after filling it up with coal in the body of heater, easily causes improper ventilation, incomplete combustion, and the thermal efficiency is low.
The purpose of this utility model provide a kind of well-ventilated, burning fully, the hot-blast stove that the thermal efficiency is high.
The utility model is real like this, and the interior cover of jacket type body of heater and shell are welded on respectively on the top iron plate of blast chamber, and a coal feeding hole is established on the top of interior cover and shell, and is provided with inner roof brick and outer bell.Be drilled with several air vents on the iron plate on the blast chamber at place, interior cover bottom, and on its circumference, be provided with some vertical blast pipes.The upper left-hand of shell is provided with chimney, and the right side is provided with hot air blast hole, and the lower left side of shell is provided with combustion-supporting blast orifice.In body of heater, pile coal cinder, ignite from the top earlier, vertical blast pipe in air blast reaches from the air vent of combustion-supporting blast orifice bottom furnace body inner housing around the cover is comprehensive blows in body of heater, make coal cinder fully burning from top to bottom, air between shell and the interior cover is heated, air blast by hot air blast hole blows out by dividing plate hot blast from hot-blast outlet, for heating, oven dry is used.
Owing to adopted such scheme, in body of heater, increased vertical blast pipe, thereby made the coal of body of heater can obtain sufficient air, reach completing combustion, improve the thermal efficiency.
Below in conjunction with accompanying drawing, the utility model is further specified.
Accompanying drawing is the cutaway view of utility model, 1 combustion-supporting blast orifice among the figure, 2 hot-blast outlets, 3 heat-insulation layers, 4 chimneys, 5 shells, cover in 6,7 outer bells, 8 inner roof bricks, 9 vertical blast pipes, 10 hot air blast holes, 11 wind isolation boards, 12 muck removal mouth and lids, 13 blast chambers, 14 air vents, 15 air vents.
As shown in the figure, jacket type furnace body inner housing 6 and shell 5 are welded in respectively on the iron plate above the blast chamber 13.Interior cover is established a coal feeding hole with the top of shell, and is provided with inner roof brick 8 and outer bell 7.Be drilled with several air vents 14 on the iron plate on the blast chamber at the place, bottom of interior cover 6, and be evenly equipped with some vertical blast pipes 9 on its circumference, the lower end of vertical blast pipe communicates with blast chamber 13, and the upper end is sealed with blanking cover.Be drilled with several air vents 15 on the circumference of vertical blast pipe from bottom to top.The upper left-hand of shell 5 is provided with chimney 4, and the right side, bottom is provided with the muck removal mouth and covers 12, and the left side is provided with hot-blast outlet 2.Be provided with hot blast dividing plate 11 between shell and the interior cover, hot blast is all blown out in order.The left side of blast chamber 13 is provided with combustion-supporting blast orifice 1, blowing-in and combustion-supporting in body of heater, and the outer surface of shell covers with insulation material 3, keeps hot blast temperature.
Claims (3)
1, a kind of coal-fired counter-burning type heating, oven dry hot-blast stove, mainly by the jacket type body of heater, blast chamber, the hot blast induction system, chimney, coal feeding hole, compositions such as muck removal mouth, it is characterized in that being drilled with several air vents on the iron plate on the blast chamber at place, interior cover bottom, and at some vertical blast pipes of its circumference uniform distribution.
