Abstract

The utility model discloses a blast and air suction dual-purpose fan to be used together with coal furnaces and kitchens, comprising a blast room and an air suction room. Blast fan blades and an air outlet are provided in the blast room; air suction centrifugal fan blades, an air inlet and an air outlet are provided in the air suction room. The blast fan blades and air suction centrifugal fan blades are fixed on a same motor shaft. The utility model can not only blow air into coal furnaces and kitchens and support combustion of coal furnaces, but also draw redundant flame and heat in the kitchen into the water tank of the furnace or kitchen to heat water. In this way, the utility model makes full use of the heat energy produced from burning of coal and significantly improves thermal efficiency. In addition, while redundant heat energy is reused, dust produced from burning of coal is also discharged from the air outlet of the air suction room, which greatly improves sanitary condition of surfaces of furnaces or ovens and surrounding environment.

Description

The dual-purpose machine of air blast air inducing

Technical field:

The utility model relates to a kind of small-sized machine that is used for air blast and air inducing, particularly with the dual-purpose machine of the matching used bulging air inducing of coal-fired stove.

Background technique:

The coal-fired stove of generally producing in the market and using all is combustion-supporting by the blower blowing, this combustion-supporting mode, and coal can produce a large amount of dusts and blow out through the kitchen range mouth from burner hearth when burning, had a strong impact on the health of kitchen range surface and surrounding environment; In addition, a large amount of ember that combustion-supporting back produces and waste heat are not fully utilized but are directly discharged by smoke-ejecting pipe, cause the heat energy serious waste, and heat loss is big, and the heat energy utilization rate is lower.

The model utility content:

At the deficiencies in the prior art part, it is a kind of not only can be to the coal-fired stove air blast combustion-supporting but also can make full use of the dual-purpose machine of bulging air inducing of ember, waste heat, the dust of having discharged when having reduced simultaneously the kitchen range burning significantly by air inducing that the purpose of this utility model is to provide.

For realizing the purpose of this utility model, take following technological scheme: the dual-purpose machine of air blast air inducing, mainly comprise motor, casing and flabellum, be provided with blast chamber and air inducing chamber two-part, be provided with air blast flabellum and exhaust outlet in the blast chamber, the indoor centrifugal flabellum of air inducing, intake grill and the exhaust outlet of being provided with of air inducing, the centrifugal flabellum of air blast flabellum and air inducing is fixed on the same motor shaft.

When using said apparatus, the exhaust outlet of blast chamber and the intake grill of cooking stove bottom are joined, the pyrotechnics pipe outlet of the intake grill of air inducing chamber and cooking stove water tank is joined, by the blast volume of adjusting blast chamber and the air inducing amount of air inducing chamber, realization is combustion-supporting and the pyrotechnics pipe that flame unnecessary in the kitchen range and heat are introduced water tank heated water tank to the burner hearth air blast, simultaneously form secondary the pressure in the kitchen range when hot igniting, the coal-fired dust that produces just can not blown out but the pyrotechnics pipe in water tank and the intake grill of air inducing chamber are drawn by the kitchen range mouth, after the exhaust outlet of air inducing chamber discharge.

As seen from the above technical solution, the utility model not only can be combustion-supporting to the coal-fired stove air blast, flame unnecessary in the kitchen range and heat introducing cooking stove water tank can also be heated it, make full use of the heat energy that fired coal combustion produces, make the thermal efficiency obviously improve, in addition, when unnecessary heat energy is recovered utilization, the coal-fired dust that produces is also discharged by the exhaust outlet of air inducing chamber, has improved the sanitary condition of kitchen range surface and surrounding environment greatly; Simultaneously, reasonable in design, the compact structure, safe and convenient to use of the utility model.

Description of drawings:

Fig. 1 is the utility model example structure schematic representation;

Fig. 2 is the left view of Fig. 1.

Embodiment:

As shown in Figure 1, the utility model is mainly by motor 1, blast chamber 2 and air inducing chamber 3 are formed, blast chamber 2 is set up in parallel with the direction of air inducing chamber 3 along motor shaft 4, in conjunction with shown in Figure 2, blast chamber comprises casing 5, air blast flabellum 7 and exhaust outlet 8, the exhaust outlet 8 of blast chamber 2 joins with the intake grill of cooking stove bottom, air inducing chamber 3 comprises casing 6, the centrifugal flabellum 9 of air inducing, intake grill 10 and exhaust outlet 11, the intake grill 10 of air inducing chamber 3 joins with the pyrotechnics pipe outlet of cooking stove water tank, the centrifugal flabellum 9 of air blast flabellum 7 and air inducing is fixed on the same motor shaft 4, is fixedly connected by bolt 12 between motor 1 and the casing 5, be fixedly connected by bolt 13 between casing 5 and the casing 6; By the blast volume of adjusting blast chamber and the air inducing amount of air inducing chamber, realization is combustion-supporting and the pyrotechnics pipe that flame unnecessary in the kitchen range and heat are introduced water tank heated water tank to the burner hearth air blast, simultaneously form secondary the pressure in the kitchen range when hot igniting, the coal-fired dust that produces just can not blown out but the pyrotechnics pipe in water tank and the intake grill of air inducing chamber are drawn by the kitchen range mouth, after the exhaust outlet of air inducing chamber discharge.

Claims

1, the dual-purpose machine of air blast air inducing, mainly comprise motor, casing and flabellum, it is characterized in that: this machine comprises blast chamber and air inducing chamber two-part, be provided with air blast flabellum and exhaust outlet in the blast chamber, the indoor centrifugal flabellum of air inducing, intake grill and the exhaust outlet of being provided with of air inducing, the centrifugal flabellum of air blast flabellum and air inducing is fixed on the same motor shaft.
