Description

Small mouth, double-layer thin-wall energy-saving stove

technical field

The utility model relates to an energy-saving stove, in particular to an energy-saving stove with a small opening and double-layer thin walls.

Background technique

With the improvement of people's living standards, coal and liquefied petroleum gas and other mineral energy are widely used in rural areas, while the utilization of biomass energy is less and less, and a large amount of crop straw is directly burned in the fields.

People have gradually realized the irreversible major defects of fossil energy, that is, the non-renewability of resources, and the increasingly heavy environmental pressure caused by the massive use of fossil energy. In the foreseeable future, mineral energy will inevitably withdraw from the stage of history. Human beings must seek new alternative energy sources in order to maintain normal living conditions, and the use of renewable biomass energy is the hope of human beings in the future.

Biogas is an important aspect of biomass energy utilization, but the excavation period of biogas digesters is long and the cost is high. It is greatly affected by the ambient temperature. The general situation is that the gas production is large in summer and cannot be used; in winter, the gas production is insufficient due to low ambient temperature and cannot be used normally. Therefore, it is difficult to promote and apply on a large scale.

Although traditional wood stoves use biomass energy as fuel, the wood stoves currently used in rural households have a relatively primitive structure, large volume, and energy combustion thermal efficiency lower than 15%. A large amount of smog is discharged outdoors, causing environmental pollution. It can be seen that improving the structure of traditional wood stoves, improving their thermal efficiency and modernization should be an important aspect of biomass energy utilization.

Contents of the invention

The purpose of the utility model is to provide a small-mouth, double-layer thin-walled energy-saving stove that is easy to use and has high firepower. To solve the technical problems of traditional firewood stoves such as low thermal combustion efficiency, large smoke, and large volume.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: the energy-saving cooker includes a cooker body and a cooker mouth, the cooker chamber is under the cooker mouth, a firewood inlet is arranged on the cooker chamber wall, and a cooker grate is installed in the center of the cooker chamber bottom. , the bottom of the stove is an air duct, the side wall of the stove is basin-shaped, and its side wall gradually shrinks to connect to the mouth of the stove, and there is a smoke outlet on the side wall. The area of the stove mouth is smaller than the The bottom area, the inner chamber wall is in the shape of an inverted water basin, and the outer chamber wall is also set outside the inner chamber wall. A cavity is formed between the inner chamber wall and the outer chamber wall. There are several air outlets communicating with the cavity, and several air inlets communicating with the cavity are arranged at the bottom of the chamber close to the inner chamber wall.

As a preference, the stove body is spliced into a box structure by a concrete vertical plate, a concrete bottom plate, and a concrete panel, and a convex line is provided on the inner wall of the concrete vertical plate, and the bottom plate of the hearth is fixed on the raised line to support the hearth, and The air duct of the box-shaped stove body is formed under the bottom plate of the stove chamber, the upper part of the concrete vertical plate is provided with a stove door connected with the stove chamber, the middle part of the concrete vertical plate is provided with an air duct opening connected with the air duct, and the bottom of the concrete vertical plate is provided with a The ash outlet connected to the lower ash box.

Preferably, there is a certain gap between the outer wall of the stove and the concrete vertical plate.

Preferably, the air outlets and air inlets are evenly and equidistantly arranged around the wall of the inner chamber.

The utility model has a small mouth of the stove and has a good heat-gathering effect. The double-layer hollow wall structure is conducive to heat insulation, and the airflow passing through the double-layer wall will absorb most of the heat emitted by the stove, and will accelerate the flow from the inner chamber. The air outlet on the wall sprays out and accumulates at the bottom of the pot, providing secondary combustion-supporting air for combustion and promoting the complete oxidation of fuel. Practice has proved that: the combustion temperature of the stove of the utility model is very high, the fuel is fully burned, the smoke is very small, and the combustion efficiency can reach 30%, which has obvious energy-saving effect compared with ordinary wood stoves. And its firepower is much greater than that of traditional stoves such as briquette stoves, gas stoves, biogas stoves, and gas stoves. Not only crop straws can be used, but also various wood debris such as branches, leaves, straw, etc. can be used.

In addition, the utility model adopts a modular design, and the stove chamber and the stove body can be spliced together, and has the advantages of convenient assembly, light weight, small volume, and good heat insulation performance. Therefore, the technical problems of traditional firewood stoves such as heavy benzene, large volume, large smoke, and energy consumption are effectively solved.
