Abstract
The utility model discloses an auxiliary air intake energy-saving return air stove, belonging to coal-fired cookers, which aims to provide with a coal-fired stove with high heat efficiency, energy conservation and simple structure. The coal-fired stove comprises a panel, a seat, a stove body for connecting the panel and the seat, an inner cavity in the stove body which is fixed on the seat, and a stove core fixed in the inner cavity. An inner cover (4) is fixed on the top portion of the inner cavity (7), an air intake ring (3) is fixed between the inner cover (4) and the stove core (11), the periphery of which is provided with air intake holes (13), a cavity between the inner cavity (7) and the air intake ring (3) are communicated with an air intake pipe (6) and the seat (8), a flue (5) fixed on the stove body (10) is communicated with the cavity between the stove body (10) and the inner cavity (7). The utility model effectively improves the air ventilating condition of a hearth, can fully burn coal, which is an ideal domestic coal-fired stove.
Description
Technical field:
The utility model relates to a kind of stove and accessory, relates in particular to a kind of coal stove.
Background technology:
At present, most of air return stoves generally adopt the combustion-supporting traditional structure of grate air intake that is arranged on burner hearth bottom, stop up grate owing to fire coal overstocks easily at burner hearth bottom, thereby usually cause the burner hearth oxygen supply deficiency, fire coal can not completing combustion; Not only the waste is big, energy consumption is high, the thermal efficiency is low, but also has many defectives such as contaminated environment.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of thermal efficiency height, energy savings, and the energy-conservation air return stove of auxiliary air intake simple in structure.
To achieve these goals, the utility model by the following technical solutions: it comprises panel, base, connects both shafts, is fixed on inner bag that is arranged in shaft on the base and the combustion chamber that is fixed on inner bag; The top of inner bag is fixed with inner cap, and the air intake circle that periphery is provided with fresh air inlet is fixed between inner cap and the combustion chamber; Inner bag is communicated with base by blast pipe with cavity between the air intake circle, and the flue that is fixed on the shaft is communicated with cavity between shaft and the inner bag.
In the cavity of blast pipe between shaft and inner bag; Blast pipe also can be positioned at combustion chamber.
On the basis of said structure, can also wall of plug-in mounting in the air intake circle be provided with the insulation plug of pore.
Compared with the prior art, the utility model is owing to increased air intake circle and inner cap on the basis of traditional air return stove, and utilize blast pipe that the cavity between inner bag and the air intake circle is communicated with for burner hearth provides auxiliary air intake with base, thereby improved effectively burner hearth ventilation condition, increased the oxygen-supplying amount in the burner hearth; Not only can make coal-fired fully burning, improve the thermal efficiency, but also reduce energy consumption; In addition, blast pipe also has the effect of air inducing, the air in therefore can the clean room.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: panel 1 insulation plug 2 air intake circles 3 inner caps 4 flues 5 blast pipes 6 inner bags 7 bases 8 grates 9 shafts 10 combustion chambers 11 pores 12 fresh air inlets 13
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: panel 1 is fixed on the base 8 by shaft 10, and the inner bag 7 that is arranged in shaft 10 is fixed on the base 8, and combustion chamber 11 is fixed in the inner bag 7, is the grate 9 that is fixed on the base 8 in the bottom of this combustion chamber; Outer setting at shaft 10 has flue 5, and this flue is communicated with shaft 10 with cavity between the inner bag 7.The top of inner bag 7 is fixed with inner cap 4, and the air intake circle 3 that periphery is provided with fresh air inlet 13 is fixed between inner cap 4 and the combustion chamber 11; Air intake circle 3, inner bag 7 and the inner cap 4 common cavitys that constitute a ring-type, the blast pipe 6 that an end is fixed on the base 8, the other end is fixed on the inner bag 7 is communicated with this cavity with base 8.Obviously, blast pipe 6 also can directly be set direct puncture and crosses combustion chamber 11 described cavity is communicated with base 8.In order to save fire coal, in air intake circle 3, can also insulation of plug-in mounting fill in 2; The through hole that the side of this plug has pore 12, the top is provided with communicates with this pore.
