Description

Environmentally friendly and energy-saving coal-fired stove

technical field

The utility model relates to a stove, in particular to a coal-fired stove.

Background technique

Traditional coal-fired stoves, especially movable honeycomb coal-fired stoves, as shown in Figure 1, have only a single stove body, and the flue gas 4 produced by coal combustion carries a large amount of heat, dust, carbon dioxide and other harmful substances. The gas is directly discharged to the surroundings from the flame port 11 on the stove body, pollutes the indoor environment, and even causes death in severe cases, and the heat in the flue gas is also wasted.

Therefore, it is necessary to improve the existing coal-fired stoves so that the flue gas produced by coal-burning can be discharged outside without polluting the indoor environment, and the heat in the flue gas can be utilized.

Contents of the invention

In view of this, the utility model provides an environment-friendly and energy-saving coal-fired stove, so that the smoke generated by coal-burning can be discharged outside without polluting the indoor environment.

The environmental-friendly and energy-saving coal-fired stove of the present utility model comprises a stove core, a shell covering the stove core, and a chimney connected with the shell. An air inlet is provided on the wall corresponding to the vent of the stove core, and a pot opening is provided on the upper surface of the shell corresponding to the flame port of the stove core, and the height of the pot port of the shell is higher than that of the flame port of the stove core.

Further, the diameter of the pot mouth of the shell is smaller than the diameter of the flame mouth of the stove core;

Further, the air inlet of the stove core communicates with the air inlet of the casing through a hollow straight pipe;

Further, the chimney is detachably connected to the casing.

The beneficial effect of the utility model is that: the utility model has a casing on the outer cover of the stove core, the casing communicates with the chimney, and the height of the pot mouth of the casing is higher than the height of the flame mouth of the stove core, so that the smoke generated by burning coal in the stove core is released from the flame. The chimney is detachably connected to the shell, and most of the chimney is placed indoors in winter, so that the heat of the flue gas is transferred to the room through the chimney, improving the Indoor temperature, the heat in the flue gas is effectively used. In summer, most of the chimneys are placed outside, and the heat of the flue gas is discharged to the outside.

Description of drawings

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings, wherein:

Fig. 1 is the structural representation of traditional coal-fired stove;

Fig. 2 is a schematic structural view of the utility model (most of the chimneys are placed indoors);

Fig. 3 is a schematic structural view of the utility model (most of the chimneys are placed outdoors).

Detailed ways

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Fig. 2 is a structural schematic diagram of the present utility model (most of the chimneys are placed indoors), and Fig. 3 is a structural schematic diagram of the present utility model (most of the chimneys are placed outdoors), as shown in the figure, the environmental protection and energy-saving coal-fired stove of the present utility model , including a stove core 1, a casing 2 overlaid on the stove core 1, and a chimney 3 communicating with the casing 2, the upper surface of the stove core 1 is provided with a flame port 11, and the lower part of the side wall is provided with a vent 12, and the side wall of the casing 2 is An air inlet 22 is provided on the wall corresponding to the vent 12 of the stove core 1, and a pot opening 21 is provided on the upper surface of the shell 2 corresponding to the flame port 11 of the stove core 1, and the height of the pot port 21 of the shell 2 is higher than that of the stove. The height of the flame port 11 of the core 1; the structure of the stove core 1 is the same as that of a traditional coal-fired stove, and the traditional coal-fired stove can be used directly; the flue gas 4 produced by burning coal in the stove core 1 is discharged from the flame port 11. The inside of the casing 2 flows, and then it is discharged outside through the chimney 3, which will not pollute the indoor environment.

As a further improvement of the present utility model, the diameter of the pot mouth 21 of the shell 2 is smaller than the diameter of the flame port 11 of the stove core 1; so that the smoke discharged from the flame port 11 is less likely to escape from the pot port 21, but in the shell 2 After internal circulation, it is discharged from the chimney 3 to improve the smoke exhaust efficiency of the chimney 3; of course, the diameter of the pot mouth can also be greater than or equal to the diameter of the flame mouth, but the sealing effect on the smoke is not as good as the above structure.

As a further improvement of the utility model, the vent 12 of the stove core 1 communicates with the air inlet 22 of the shell 2 through the hollow straight pipe 5; the air 6 required for combustion enters the stove core 1 from the hollow straight pipe 5, which improves the The ventilation effect of the coal-fired stove makes the combustion more complete.

As a further improvement of the utility model, the chimney 3 is detachably connected to the shell 2; most of the chimney 3 is placed indoors in winter, and the heat of the flue gas 4 is transferred to the room through the chimney 3, thereby increasing the indoor temperature and effectively utilizing the smoke. The heat in the gas 4 is shown in Figure 2; most of the chimney 3 is placed outdoors in summer, and the heat of the flue gas 4 is discharged to the outside, as shown in Figure 3.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the utility model without limitation, although the utility model has been described with reference to the preferred embodiment of the utility model, those of ordinary skill in the art should understand that, Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
