Background

The heating furnace is common heating equipment and mainly comprises a return air furnace, a biomass particle heating furnace, an electric warming furnace and the like. Among them, the heating furnace, which needs to be burned using solid fuels such as coal, biomass particles, etc., is widely used because of its characteristics of large firepower, wide thermal coverage, etc. The heating furnace comprises a furnace surface, a furnace body, a furnace core, a base, a dust removing device, an ash box and the like; wherein the furnace core is a core component of the heating furnace; the current furnace core is mainly a core body which penetrates in the axial direction. When in use, the furnace core is placed in the furnace body until the bottom of the furnace core is contacted with the ash removing device on the base; then the fuel is put into the core body and ignited, and the fuel provides oxygen for the combustion of the fuel through an air inlet arranged on the furnace body. In this way, the fuel is continuously combusted, but because the wind flow delivered by the wind inlet is accumulated at the bottom of the core, the wind flow is almost completely consumed at the bottom of the core, and the fuel is not completely combusted at the moment, a large amount of smoke is generated, the fuel is insufficiently combusted, and the fuel resource is wasted. In addition, because the fuel is mainly concentrated on the bottom of the core body for combustion, the flame generated at the top of the core body is very small, so that the temperature rising speed of the stove surface is slow, and the daily operation of cooking food and the like is not facilitated.

In order to solve the problem, the applicant further improves the furnace core, so that the strength of the flame at the top of the core body is improved, the use amount of fuel is reduced, and the waste of the fuel is further reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a heating stove to solve the problem that the heating stove in the prior art needs a large amount of burning fuel, just enables the furnace face rapid heating up.

The heating furnace comprises a base, an ash box, an ash removing device, a furnace body, a furnace core and a furnace surface; the ash box and the ash removing device are arranged in the base, the furnace body is fixedly connected to the base, and an air inlet is formed in the furnace body; the furnace surface is fixedly connected to the furnace body, and the furnace core is positioned in the furnace body and is arranged on the ash removing device; the base is provided with an air supplementing hole which is positioned between the furnace body and the furnace core; the stove core includes the core that the axis direction runs through, and the wall body of core is fitted with a contraceptive ring and is equipped with a plurality ofly rather than the communicating ventilation hole in inside, and the ventilation hole is located the first half section of core.

The working principle and the beneficial effects of the scheme are as follows: when in use, fuel is placed in the furnace core and ignited; the fuel is burnt at the bottom of the furnace core, and the burning degree of the fuel can be controlled by controlling the opening size of the air inlet. The incompletely burnt fuel forms mixed combustible gas which quickly rises to the upper half section of the furnace core; because the base is provided with the air supplementing hole, the air supplementing hole is positioned between the furnace body and the furnace core; external air can enter the furnace body from the air supplementing hole on the base, and the temperature of the air in the furnace body is higher due to the combustion of fuel in the furnace core, so that a large amount of external air enters the furnace body; air entering the furnace body enters the core body from the vent holes and rapidly supplements oxygen to the combustible gas, so that the uncombusted completely mixed combustible gas is promoted to be combusted secondarily. Because the fuel of the upper half section of the core body is closer to the furnace surface during combustion, the flame generated by the fuel can directly act on the furnace surface, and the temperature of the furnace surface is promoted to be rapidly increased. Therefore, the heating furnace in the scheme can realize the rapid temperature rise of the furnace surface under the condition of using less fuel, and the waste of the fuel is greatly reduced.

Furthermore, the ash removing device comprises a pull rod and an ash removing plate, and one end of the pull rod is fixedly connected to the ash removing plate; the bottom of the ash removing plate is connected with an ash baffle plate used for sealing the ash leakage hole in a sliding manner; one end of the pull rod, which is far away from the ash removing plate, penetrates through the base and extends out of the base; the ash removing plate is positioned right above the ash box; the base is provided with a supporting plate for supporting the ash blocking plate. The ash removing device in the prior art generally uses a furnace bridge, and when ash materials are removed from the furnace bridge, fuel easily drops into an ash box from the gap of the furnace bridge; but also easily causes the fuel to be broken when the furnace bridge is pulled, thereby further increasing the loss of the fuel. The dust removing plate, the dust baffle plate and the dust leakage hole are arranged; when ash materials generated after fuel combustion fill ash leakage holes in the ash removing plate, the ash removing plate is pulled by the pull rod, and at the moment, the ash materials in the ash leakage holes are pulled and separated from the furnace core; the space left by the ash leakage hole is filled by the upper surface of the ash removing plate, and the upper surface of the filling part of the ash removing plate supports the fuel to be continuously combusted. When the ash leakage hole is pulled to be separated from the ash baffle, ash materials which are not supported by the ash baffle fall into the ash box below. After the ash falls into the ash box, pushing the ash removing plate through the pull rod until the ash leaking hole is positioned right below the furnace core; in the process, the ash blocking plate realizes the support of ash again, so that the ash blocking plate can be used continuously.
