Description

Novel dual-purpose domestic straw boiler of a heating, cooking machine

Technical Field

The utility model belongs to the technical field of living beings gas appliance, concretely relates to heating, a dual-purpose novel domestic straw boiler of a machine of cooking.

Background

With the aggravation of greenhouse gas effect and the frequent appearance of haze phenomenon in China caused by fossil energy consumption, the environmental awareness of human beings is continuously strengthened, so that how to inhibit pollution emission from the source becomes important, and the search for a clean and reliable energy is urgent. Biomass can be widely regarded as "CO₂Zero-emission environment-friendly renewable energy, so that biomass energy application is valued worldwide. Among them, the straw (cotton stalk, tree branches, corn stalk, wheat stalk, etc.) is a waste of agricultural production, and burning it in the field wastes precious resources and pollutes the atmospheric environment. The straw is a biomass fuel and a renewable energy source, the straw is fully combusted to generate heat energy, and the biomass fuel has social benefits of saving energy and preventing environmental pollution and also has good economic benefits.

In daily life, a coal-fired boiler is used for heating. Although the small household heating stove can be used for heating and cooking, the small household heating stove can only be used for small heating of civil houses, the function of large-area heating cannot be achieved, so that a boiler is required for large-area heating, but the boiler cannot be used for cooking, and therefore, an ideal product for simultaneously heating and cooking in the civil buildings does not exist at present. And the small-sized heating furnace has low heat efficiency, large coal consumption and large waste, so that users often need to purchase two furnaces, one furnace is used for cooking and the other furnace is used for heating. Thus, the investment is increased, the economic burden of users is increased, the coal consumption is increased, the waste is caused, and the environmental pollution is increased.

In order to achieve the above purpose, the utility model discloses technical scheme as follows:

a new kind of heating, cook one dual-purpose domestic straw boiler, including boiler body, cold water pipe and heat exchange tube;

a combustion chamber is arranged in the boiler main body, a smoke exhaust pipeline communicated with the outside is arranged on one side wall of the boiler main body, and an openable furnace door is arranged on the corresponding side wall and used for adding fuel; the top end of the boiler main body is provided with a heating port communicated with the combustion chamber, and a pot is placed at the heating port for heating;

one end of the cold water pipe is connected with an external water source, and the other end of the cold water pipe is connected with a cold water inlet of the heat exchange pipe;

the heat exchange tube is arranged on the peripheral wall of the combustion chamber without an opening part to form a water jacket interlayer, and a hot water outlet of the heat exchange tube is communicated with a water inlet pipeline of the heating radiator to form circulating heating.

Furthermore, the external water source is a water outlet pipe of the heating radiator.

Furthermore, a fire bar is additionally arranged on the heating port and used for placing a flat-bottomed pot or a pot with a small diameter.

Furthermore, the oven also comprises an oven cover which covers the heating opening when the oven is not used for cooking.

Further, the heat exchange tube includes circular water pipe and the square water pipe of intercommunication each other, and circular water pipe is snakelike crooked form, sets up and forms the water jacket intermediate layer at the combustion chamber top not opening portion and left and right sides, and square water pipe sets up in boiler main part side corner.

Has the advantages that: the utility model has simple structure, and can cook food while warming by connecting the heating radiator in a water heating mode; the internal structure is entirely composed of pipes, the heat utilization rate is very high, the direct heating by burning straws transfers heat through the pipes inside, the combustion chamber has large capacity and can use straw biomass as fuel for heating; the energy is converted into high-quality energy, thereby promoting the economic development of rural areas, protecting the environment, saving energy and reducing consumption.
