Description

Energy-saving high-fire stove with waste heat from the stove wall preheating the air intake

technical field

The utility model relates to a high-fire stove, in particular to an energy-saving high-fire stove for preheating air intake by waste heat of the stove wall.

Background technique

In the kitchens of hotels, hotels, restaurants, and the canteens of school organizations, gas cookers called fierce stoves are inseparable. This kind of cooker has a large firepower and is suitable for rapid cooking of a large amount of dishes. Therefore, it is welcomed by users.

Existing high-fire stoves include a stove body, a stove core is arranged at the center of the stove bottom of the stove body, a gas intake pipe is arranged on the stove core, and an intake pipe is also arranged on the stove core to be connected with a blower. The blower blows the air into the stove core and mixes it with the incoming gas for combustion. During combustion, a large part of the heat is lost through the stove wall of the high-fire stove. At present, the heat is lost in vain, which cannot save energy and reduce consumption.

Utility model content

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide an energy-saving high-fire stove in which waste heat from the stove wall is preheated into the air to save energy and reduce consumption.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: an energy-saving high-fire stove for preheating the air intake by waste heat of the stove wall, including a stove body, a stove core and a gas inlet pipe, and the feature is that the stove body includes The upper end is provided with the inner casing of the stove mouth, the stove core is installed on the bottom plate of the inner casing, and a sealed hot air interlayer is arranged outside the inner casing, the lower end of the stove core communicates with the bottom of the sealed hot air interlayer, and the sealed hot air interlayer The upper part of the side wall is provided with an air inlet connected with the air inlet device, and the gas inlet pipe passes through the outer wall of the sealed hot air interlayer and communicates with the bottom end of the stove core.

Using the above scheme, 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. During the process of rotating from top to bottom, the wind is fully Use the heat from the stove wall of the stove body to achieve 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 burns after premixing with the gas coming in from the gas inlet pipe to reduce heat energy. loss, to achieve the effect of energy saving and consumption reduction. 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.

In the above solution: the upper part of the inner wall of the inner casing is circumferentially distributed with secondary combustion air gathering small holes. Part of the wind (air) entering the sealed hot air interlayer is blown out from the secondary combustion air gathering holes, so that the incompletely burned gas is mixed with the air again, which is conducive to full combustion.

In the above solution: the centerlines of the inner shell, the stove core, and the gas inlet pipe are on the same straight line. Easy to design and install.

In the above scheme: the side wall of the sealed hot air interlayer is evenly distributed with at least two air inlets in the circumferential direction on the upper part, the air inlet device includes a blower and an air distribution shell, and the air distribution shell is arranged outside the sealed hot air interlayer. There is a gap between the air distribution shell and the outer wall of the sealed hot air interlayer. The air distribution shell and the outer wall of the sealed hot air interlayer enclose a sealed air distribution chamber. The air distribution shell is provided with an air inlet pipe connected to the blower. The gas inlet pipe stretches out of the air distribution shell.

In this way, the air from the blower first enters the air distribution cavity, and then evenly enters the sealed hot air interlayer from the air inlets in multiple directions, so as to avoid the uneven fire caused by the uneven air intake of the stove core.

In the above solution: the side wall of the sealed hot air interlayer is evenly distributed with three air inlets in the circumferential direction near the upper part. Conducive to uniform air intake.

Beneficial effect, the utility model improves the structure of the high-fire stove body, fully utilizes the heat emitted from the high-fire stove wall to preheat the air, and achieves the purpose of saving energy and reducing consumption. At the same time, the utility model can also realize full combustion of fuel, To achieve the effect of energy saving and emission reduction.
