Description

Energy-saving hot air premixed fire stove

technical field

The utility model relates to a high-fire stove, in particular to an energy-saving hot air premixed high-fire stove.

Background technique

In the kitchens of hotels, hotels, restaurants, and the canteens of school agencies and organizations, gas or oil stoves called fierce fire stoves are inseparable. This kind of stove has a large firepower and is suitable for fast cooking of large quantities of dishes. Therefore, it is welcomed by users.

Existing high-fire ranges include a stove body, a stove core is arranged at the center of the stove bottom of the stove body, and a gas inlet pipe or a fuel oil inlet pipe is arranged on the stove core (the gas inlet pipe is generally arranged at the bottom of the stove core, and the fuel oil inlet pipe is arranged at the bottom of the stove core). The lower part of the side wall), and the stove core is also provided with an air inlet pipe to be connected with the blower. The blower blows the air into the stove core and mixes it with the incoming fuel or gas for combustion. During combustion, a large part of the heat is lost through the stove wall of the high-fire stove, and there is also a large amount of waste heat in the waste gas generated after combustion. At present, these heats are all in vain. Emission loss cannot achieve the effect of saving energy and reducing consumption.

Secondly, although air and fuel oil or gas are premixed in the stove core and then burned, there is still a phenomenon of insufficient combustion. There is a small amount of fuel or gas in the exhaust gas, which is directly discharged, which not only pollutes the environment, but also causes a waste of energy.

Utility model content

Needling on the needles of the prior art, the technical place to be solved by the utility model is: how to provide an energy-saving hot-air premixed high-fire stove that saves energy and reduces consumption.

For the sake of the above-mentioned technology, the utility model adopts the following technical scheme: an energy-saving hot air premixed high-fire stove, including a stove body, a stove core and a gas inlet pipe, and the feature is that the needle stove body includes an upper end The inner casing of the stove mouth is set, the stove core is installed in the center of the bottom plate of the inner casing, the inner casing is provided with a sealed hot air interlayer, the lower end opening of the stove core communicates with the sealed hot air interlayer, and the hot air interlayer is sealed The upper part of the side wall is provided with an air inlet, and the bottom center of the sealed hot air interlayer is provided with a gas inlet pipe, and the gas and the inlet air are mixed and enter the stove core from the lower end of the stove core;

The range body also includes an outer shell with an open upper end, there is a gap between the outer shell and the outer wall of the sealed hot air interlayer, and the outer shell and the outer wall of the sealed hot air interlayer enclose a secondary combustion exhaust chamber, and the outer shell The upper port of the inner shell is provided with an inner flanging extending to the stove mouth of the inner shell. The inner flanging is located above the top of the inner shell, and there is a gap between the top of the inner shell and the gas generated after combustion. The gap between the edge and the top of the inner casing enters the secondary combustion exhaust chamber; the bottom surface of the outer casing is provided with an exhaust pipe for discharging the burned gas;

The cooker body also includes a blower air intake casing with an upper opening located outside the casing. There is a gap between the blower intake casing and the casing. The gas inlet pipe and exhaust pipe extend outside the blower air intake casing. The needle air inlet extends to the outside of the air blower air inlet casing and is connected with the air outlet pipe of the blower blower, and the bottom plate of the needle blower air inlet casing is provided with an air exhaust port to be connected with the air inlet of the blower blower.

We set up a sealed hot air interlayer outside the stove. The cold air enters the sealed hot air interlayer from the upper part through the blower, and rotates in the sealed hot air interlayer to reach the bottom of the stove body. When the wind rotates from top to bottom, it makes full use of the stove body The heat from the stove wall achieves the effect of preheating. After preheating, the hot air enters the stove core through the air inlet channel on the side wall of the stove core, and then burns after premixing with the gas coming in from the gas inlet pipe, reducing the loss of heat energy and achieving The effect of saving energy and reducing consumption. After the gas is mixed with the incoming air, it enters from the lower end of the stove core, and the gas and air can be premixed, which is conducive to full combustion.

The exhaust gas generated by the combustion in the stove enters the secondary combustion exhaust chamber, where it is fully burned for the second time, and at the same time, it is heated by the cold air entering the sealed hot air interlayer. Recycling heat energy further achieves the effect of saving energy and reducing consumption.

The air intake of the blower enters the gap between the blower intake shell and the outer shell from the upper opening of the blower air intake shell, is preheated by the waste heat of the combustion exhaust gas in the shell, and then enters the sealed hot air interlayer through the blower, further as high The temperature of the air preheating further has the effect of saving energy and reducing consumption. Reduce the temperature of the wall of the high-fire stove, and the cook will not be so hot when cooking in the hot summer.

In the needle-up scheme: the upper part of the inner wall of the inner shell of the needle is circumferentially distributed with secondary combustion air-gathering small holes. The wind (air) that enters the sealed hot air interlayer is blown out from the secondary combustion air gathering holes, so that the fuel or gas that has not been fully burned is mixed with the air again, which is conducive to full combustion.

The centerlines of the inner shell, the stove core and the gas inlet pipe are on the same straight line. Easy to make and install.

Beneficial effect, the utility model makes full use of the heat emitted by the wall of the high-fire stove and the waste heat of the waste gas generated by combustion to preheat the air through the improvement of the structure of the high-fire stove body, so as to achieve the purpose of saving energy and reducing consumption. It can realize the full combustion of fuel and achieve the effect of energy saving and emission reduction.
