Background technique

As we all know, my country is a country with relatively serious shortage of coal and oil resources. In order to save coal and petroleum fuel resources and reduce the cost of living, combined with the characteristics of large rural population and wide distribution in my country, many civilian wood stoves have been developed on the market. Because these civilian wood stoves not only have high thermal efficiency, the cost of fuel The cost is low, the characteristics of waste materials can be fully utilized, and the wood stove is small in size, light in weight, convenient and safe to use. Therefore, it is used as a stove for vast rural and suburban families and small and medium-sized catering shops and stalls, and is more and more favored by people. But existing these civil firewood stoves still have some deficiencies in the use process: the one, because firewood directly burns insufficiently in the combustion zone, the heat efficiency of firewood combustion is not high enough, and firewood consumption is bigger; When the wood stove is burned, it will produce more ash and smoke, which is not conducive to food hygiene and environmental protection.

Utility model content

Aiming at the problems existing in the above-mentioned civil wood stoves in the prior art, the utility model provides a novel high-efficiency energy-saving gasification wood-saving stove with high combustion efficiency, energy saving and environmental protection, and convenient operation.

The technical solution adopted for the technical problem to be solved by the utility model is: the new high-efficiency energy-saving gasification wood-saving furnace includes a furnace platform, a furnace core, an annular bellows, a feeding hopper and a push rod, and an annular bellows is arranged outside the furnace core , the upper side wall of the furnace core is provided with staggered distribution of convection holes, the air enters the inner cavity of the furnace core evenly from the annular bellows through the convection holes, a feeding hopper is connected to the lower end of one side of the furnace core, and a pushing material is arranged in the feeding hopper One end of the hopper is horizontal or inclined and connected to the lower end of one side of the furnace core, and gasification holes are arranged on the two sides and the top surface of the hopper between the furnace core and the annular air box, and the air passes through the annular air box The gasification hole enters the connection between the furnace core and the hopper, so that the combustible gas generated after the carbonization of the firewood is burned at high temperature in the inner cavity of the furnace core.

In the utility model, since a gasification zone is formed between the furnace core and the hopper, the firewood is first preheated and carbonized to generate combustible gas, and an annular air box with a ring-shaped convection hole is arranged on the upper part of the furnace core, so that the combustible gas can be made The volatile gas forms convective high-temperature back-burning in the inner cavity of the furnace core, and the combustion is more complete, which not only strengthens the combustion effect, improves the combustion efficiency of the wood stove, saves firewood, and the wood stove does not produce smoke and dust, which is beneficial to sanitation and the environment. Protect.

Detailed ways

Embodiment 1, as shown in Figures 1 and 2, the novel high-efficiency energy-saving gasification firewood-saving stove includes an annular wind box 1, a furnace core 13, a furnace platform 3, a hopper 5, and a push rod 6, and the furnace core and The cross section of the annular air box is circular, and an annular air box 1 is arranged on the upper side wall of the furnace core 13. The furnace platform 3 is located on the top surface of the furnace core 13, and convection holes are arranged in a staggered manner between the annular air box and the upper part of the furnace core. 2. There are three rows of convection holes, with 16 convection holes in each row. The convection holes are round holes and are distributed in a circular staggered manner. The cross section of the feeding hopper 5 is square, and one end of the feeding hopper is inclined to the lower part of the furnace core. The sides are connected and connected, the inclination angle between one end of the hopper and the horizontal plane is not more than 45°, a pusher rod is arranged in the hopper, and gasification holes 12 are arranged on both sides and the top surface of the hopper between the furnace core and the annular bellows , the gasification hole communicates with the annular air box 1 through the air delivery pipe 4, and the annular air box can be directly connected with the main air inlet pipe 11. In order to further improve the combustion effect, an inclined plate 8 is movable at the bottom of the furnace core. When not in use, the inclined plate can be drawn out from the furnace core to facilitate ash removal and cleaning. There are staggered distribution of oblique air inlet holes 9 on the inclined plate. The air storage box 10 can be set on the lower end wall on the other side of the furnace core, and the air enters the air storage box 10 from the total air inlet pipe 11.
