Description

High-efficiency and energy-saving coal-fired furnace

technical field

The utility model relates to a coal stove used for catering industry.

Background technique

At present, the main structure of the coal stove used in the catering industry provided on the market is: the furnace shell with the furnace inside is supported by the base, the bottom of the furnace is provided with a furnace bar, and the inner cavity of the base with the furnace door is connected with the furnace. The inner cavities of the gallbladders communicate with each other, and an air supply pipe leads into the base. For the coal stove of this structure, when it is necessary to increase the firepower in use, an air blower is connected to the outer end of the air supply pipe, and the air is supplied by the air blower to the furnace. The deficiency that above-mentioned coal furnace exists is: though blower can accelerate combustion, increase firepower, but can cause coal combustion not enough, because coal combustion is not enough, therefore can produce larger smoke dust (contain more in the smoke dust Combustible but future and burning composition), therefore, coal consumption is bigger, and also caused the pollution to environment; In addition, firepower is still not strong enough.

Purpose of utility model

The purpose of the utility model is to provide a high-efficiency energy-saving fire-injected coal stove, which can generate more powerful firepower, and enable coal to burn more fully, and has less pollution to the environment.

In order to achieve the above object, the utility model adopts the following scheme:

High-efficiency and energy-saving fire-injected coal furnace, the furnace shell is equipped with a furnace, the bottom of the furnace is equipped with furnace bars, the furnace shell is supported by the base, the inner cavity of the base communicates with the inner cavity of the furnace, and the base is equipped with a furnace door. The air supply pipe leads into the base, there is an annular cavity between the furnace shell and the furnace, and the upper end of the furnace supports a ring-shaped air supply ring with a cavity, and the opening in the middle of the air supply ring is connected to the upper port of the furnace , the cavity of the air supply ring is connected to the cavity between the furnace shell and the furnace, and there are more than two through holes connected with the cavity along the edge of the opening on the air supply ring, and each through hole is inclined upward toward the port. The center of the air supply pipe is connected with a branch supply air pipe connected with it, and the branch supply air pipe leads to the cavity between the furnace shell and the furnace gall.

It can be seen from the above scheme that when the outer end of the air supply pipe is connected with a blower to blow air into the furnace, the blower also supplies air to the cavity of the air supply ring, and the wind in the air supply ring is sprayed from the through hole toward its opening. out. When the flame in the furnace and the smoke containing combustible components go up to the opening of the air supply ring, they will burn further under the combustion aid of the wind ejected from the through hole, so that the firepower at the opening will be more intense. Since the combustible components in the soot are further burned, the soot produced is also smaller.

The structure of the utility model is reasonable, the flame produced is strong, stable and uniform, and the coal consumption is small, and there is basically no pollution. In addition, because the utility model has a more reasonable air supply, compared with the existing coal furnace, the air blower installed The power is also less.

Detailed ways

Below in conjunction with embodiment and accompanying drawing further illustrate the utility model.

Referring to Fig. 1, the furnace shell 4 is provided with a furnace 6, the bottom of the furnace 6 is provided with a furnace bar 3, the furnace shell 4 is supported by the base 1, and the base 1 is provided with a furnace door 2, and the inner cavity of the base 1 and the furnace The inner cavity of 6 communicates, and a air supply pipe 17 leads in the base 1. The above is prior art. There is an annular cavity 5 between the furnace shell 4 and the furnace 6. The upper end of the furnace 6 supports an annular air supply ring 8 with a cavity 9. The opening 11 in the middle of the air supply ring 8 is connected to the upper port of the furnace 6. catch. Two connection pipes 7 are connected to the air supply ring 8, and the connection pipes 7 are extended to the cavity 5 between the furnace shell 4 and the furnace 6, so that the cavity 9 of the air supply ring 8 is connected to the space between the furnace shell 4 and the furnace 6. Cavity 5. Two or more through holes 10 communicating with the cavity 9 are evenly distributed on the air supply ring 8 along the edge of the opening 11 , and each through hole 10 is inclined upward toward the center of the opening 11 . In this embodiment, the through hole 10 on the air supply ring 8 is located on its inner side. On the air supply pipe 17, a section of branch air supply pipe 16 communicating with it is connected, and the branch supply air pipe 16 leads to the cavity 5 between the furnace shell 4 and the furnace 6.

Referring to Fig. 3, the air supply pipe 17 is two sections, and the air supply pipe 17 of the two sections is connected with two dampers 18 connected to each other. A flashboard 19 is arranged. Referring to Fig. 1 and Fig. 2, two cranks 13, 15 are hinged on the outside of the furnace shell 4, a connecting rod 14 is hinged between the two cranks 13, 15, a handle 12 is connected to the upper end of one crank 13, and the lower end of the other crank 15 Hinged with plate 19.

It can be seen from Fig. 1, Fig. 2 and Fig. 3 that pushing and pulling the handle 12 can manipulate the plate 19 between the two air doors 18 to move, thereby controlling the opening size of the port 20 and realizing the air intake in the furnace 6 and the air supply ring 8 control.

Referring to Fig. 4, the air supply ring 8 is circular.

Referring to FIG. 5 , the through hole 10 on the air supply ring 8 is located at the junction of its inner surface and the upper end surface.

It can be seen from Fig. 1 that when the outer end of the air supply pipe 17 is connected with a blower to blow air into the furnace 6, the blower also supplies air to the cavity 9 of the air supply ring 8 through the cavity 5, and the air supply in the air supply ring 8 The wind blows out from the through hole 10 toward the through port 11 . When the flame in the furnace 6 and the soot containing combustible components go up to the opening 11 of the air supply ring 8, they will be further combusted under the combustion aid of the wind ejected from the through hole 10, so that the firepower at the opening 10 will be further enhanced. Violent, forming a fire-breathing flame. Since the combustible components in the soot are further burned, the soot produced is also smaller. In addition, the airflow in the cavity 5 will absorb part of the heat in the furnace 6, so the surface temperature of the furnace shell 4 will decrease, and the air blown out from the through hole 10 is hot air.
