Abstract

Disclosed is a coal stove exhaust pipe, which is mainly composed of a pipe body, pipes, an upper sealing layer, an air duct and an exhaust reflection plate. Wherein, a plurality of pipes are arranged in the pipe body; the upper sealing layer of the pipe is arranged at the upper orifice of every pipe; the lower orifice of every pipe is connected with the air duct; the exhaust reflection plate is arranged at one end of the air duct. The utility model improves greatly the burning effect in the furnace, the coal is burned completely, and the burning efficiency of the coal is increased. When the coal is burning in the stove, the stove is smokeless, energy saving and environment protecting. Meanwhile, the cost of the coal stove is reduced; the maintenance fee and the workers are saved.

Description

The coal stove blast pipe

The utility model relates to a kind of coal stove blast pipe.

The coal-fired stove of Shi Yonging mostly uses chimney as blast pipe in the market, and chimney generally is located at the upper end of coal-fired stove, and is upright; Make burning of coal insufficient by the chimney emission gases, be easy to generate coal smoke and be discharged in the air by chimney, cause the pollution of environment, this chimney exhaust simultaneously also causes the thermal efficiency of coal-fired stove low, burning of coal is insufficient, causes a large amount of wastes of coal, and large-scale coal-fired stove also needs to establish tall and big chimney, it is big to take up room, the many troubles that cause transportation and install; Traditional chimney coal-fired stove also needs some auxiliary devices simultaneously, as air blast, air-introduced machine, reductor etc., has increased cost, causes maintenance and operating personnel many.

At the shortcoming that prior art exists, the purpose of this utility model is to provide a kind of coal stove blast pipe, utilizes aerodynamic principle to make air communication in the burner hearth cross the utility model and extraneously forms circulation, and gas square channel under the body of heater is discharged; Make coal-fired stove energy-conserving and environment-protective efficiency of combustion height.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of fire grate tracheae, mainly form by pipe body, pipeline, last confining bed, air channel and exhaust deflecting plate; It is characterized in that; A plurality of pipelines are located in the pipe body, each pipeline upper port place be provided with pipe body on confining bed, the lower port of each pipeline and air channel are communicated with, the end in the air channel is provided with the exhaust deflecting plate.

Above-mentioned air channel is horizontal trapezoidal shape, and the opening direction of wide end and pipeline is consistent; Wide end termination in the air channel is provided with the exhaust deflecting plate.

Above-mentioned pipeline is spiral or Zigzag type; It is suitable for reading opposite with opening angle direction end opening.

Above-mentioned pipe body is the cavity that water cavity formula water jacket body or fire-resistant heat insulating material are made.

One side of pipe body is corrugated hearth body.

Pipe body is positioned at coal-fired stove lower furnace place, becomes one near inboard wall of burner hearth and inboard wall of burner hearth.

Pass through the utility model, the coal stove blast pipe, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the utility model is simple in structure, easy to make, by the utility model, improved the combustion efficiency in the body of heater greatly, make burning of coal abundant, improved burning of coal efficient, smokeless when making the coal-fired stove burning, energy-saving and environmental protection; The cost of coal-fired stove is reduced, saved maintenance cost and personnel.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is the utility model structural representation:

Fig. 2 is Fig. 1 schematic side view.

The utility model coal stove blast pipe is located at pipe body and is positioned at coal-fired stove lower furnace place, becomes one near inboard wall of burner hearth and inboard wall of burner hearth; As shown in Figure 1 and Figure 2, the utility model coal-fired stove blast pipe mainly is made up of pipe body 1, pipeline 2, last confining bed 3, air channel 4 and exhaust deflecting plate 5; Wherein, a plurality of pipelines 2 are located in the pipe body 1, each pipeline 2 upper port place be provided with pipe body 1 on confining bed 3, the lower port of each pipeline 2 and air channel 4 is communicated with; Air channel 4 is horizontal trapezoidal shape, and wide end is consistent with the opening direction of pipeline 2; 4 wide end termination is provided with exhaust deflecting plate 5 in the air channel.

Above-mentioned pipeline 2 is spiral or Zigzag type; It is suitable for reading opposite with opening angle direction end opening; The density etc. of being provided with of the angle of its opening direction and the size of bore, open amount, pipeline 2 is all determined according to the capacity of the coal stove burning needs of different size and the needs that form burning " three districts " (preheating zone, primary zone, burning-out zone).

Above-mentioned pipe body 1 is the cavity that water cavity formula water jacket body or fire-resistant heat insulating material are made; One side of pipe body 1 is that waveform becomes hearth body, makes the unobstructed burner hearth sealing state that do not destroy again of body of heater air intake.

In sum, be preferred embodiment of the present utility model, all equivalent technologies of doing according to technical solutions of the utility model are replaced, and all belong to protection domain of the present utility model.
