Description

High-efficiency gasification and energy-saving wood stove

technical field

The utility model relates to a high-efficiency gasification and energy-saving wood stove.

Background technique

Burning firewood for cooking and boiling water is a traditional habit in the vast cities and towns and rural areas of our country. However, the old kang stoves that have been used for many years consume a lot of wood and crop straw because of their low combustion rate, which leads to the deterioration of the ecological environment and affects my country's economy and development. Social development. Therefore, it is imperative to develop a firewood-saving stove with very good firewood-saving effect. Over the years, many individuals or units have researched many firewood-saving stoves, such as secondary air supply structure, flue gas recycling and other measures, and achieved certain firewood-saving effects, but it seems to have reached the limit in recent years. Without further improvement, these wood stoves still have many shortcomings: the fuel is not fully burned and the heat generated by the combustion cannot be directly absorbed, resulting in low fuel utilization; when fuel such as firewood is burned, more dense smoke and dust will be generated from the pot. If it floats out from the gap between the bottom and the hob, it will not only choke people, but also the dust will stick to the kitchen utensils and stove, which will cause trouble for cleaning; frequent refueling operation is inconvenient; the gap between the furnace body charging door and the furnace body The sealing ring is directly installed on the furnace body. If the fuel burns for a long time, the heating temperature of the furnace body will be high, which will easily cause the sealing ring to be deformed by heat, affect the sealing performance, and cause smoke leakage, and even damage the sealing ring, reducing its life; the air supply device is generally equipped with The blower cannot flexibly adjust the firepower according to the needs when using it. It can only be adjusted by turning on or off the power of the fan. If the pipe returns to the fan, the fan will be damaged and its service life will be shortened.

Contents of the invention

In order to solve the deficiencies of the prior art, the utility model provides a high-efficiency gasification energy-saving wood stove in which firewood or other fuels can be fully burned and has high thermal efficiency.

In order to achieve the above purpose, the technical solution adopted by the utility model is: high-efficiency gasification and energy-saving wood stove mainly includes a furnace body, and the inner cavity of the furnace body is divided into a feeding area and a combustion area; There is a furnace pan; a firewood pushing board is set in the feeding area, and a charging door is provided on the furnace wall at the side of the feeding area, and a firewood pushing device is provided on the charging door. In the combustion area, there is no need to frequently refuel, and the operation is very convenient; the furnace body is equipped with a furnace with multiple secondary ventilation holes and an air supply device on the side of the furnace body, and the air inlet pipe communicates with the combustion area; The air supply device continuously delivers air to the combustion area, which can make the fuel placed in the combustion area fully contact with oxygen to achieve the effect of full combustion, effectively use the secondary combustion, and can quickly ignite and burn without smoke, so as to achieve The purpose of energy saving; the air inlet pipe of the air supply device is provided with a damper plate that can adjust the size of the air volume, and the damper plate is connected with the air volume adjustment and the fan switch contact rod. The position of the door panel controls the air volume. When the air volume is adjusted and the fan switch contact rod presses the fan switch contact piece, the damper is completely closed, and the fan is turned off at the same time, so that the heat in the combustion area cannot flow back to the fan after the fan is turned off, thereby Ensure the service life of the fan.
