Description

Multifunctional wood-coal dual-purpose energy-saving stove

technical field

The utility model relates to an energy-saving stove, in particular to a multifunctional energy-saving stove suitable for installation and use in rural and pastoral areas.

Background technique

In rural and pastoral areas, stoves are used for cooking and kang, and heating boilers are used for heating. The stovetops in the prior art generally use adobe or bricks to build a pottop. A pot is placed on the pottop. There is a stove hall under the pot. furnace helmet. The stove with this traditional structure has a lot of heat energy absorbed by the stove, the energy utilization rate is low, and it only has the functions of cooking and heating. The heating boilers in the prior art are generally installed separately in the kitchen, occupying an independent space, and due to manufacturing cost constraints, the overall structure is relatively small, resulting in unreasonable design of the boiler combustion chamber and air distribution, and low combustion efficiency. In the prior art, there is also a multifunctional stove in which a stove and a boiler are integrated, but this type of stove is generally only suitable for burning coal or burning firewood such as crop stalks.

Contents of the invention

The purpose of the utility model is to provide a multi-functional firewood and coal dual-purpose energy-saving stove, which has the functions of cooking and cooking, heating the kang and heating the indoor water heating radiator, and has a simple structure and high thermal efficiency, and is suitable for burning coal and firewood. Used in rural pastoral areas.

The purpose of this utility model is achieved in this way: a multi-functional firewood and coal dual-purpose energy-saving cooker is characterized in that: it comprises a lower combustion chamber, a middle combustion chamber, an upper combustion chamber and a chimney. The combustion chamber is narrow, and the lower combustion chamber, the middle combustion chamber and the upper combustion chamber are surrounded by water jackets; There is a compartment in between, and there is a burner and a burner baffle on the compartment; below the middle combustion chamber, there is a middle furnace grate with a furnace door and a furnace door on the side; under the lower combustion chamber, there is a lower furnace grate with a furnace door and a side. The furnace door; the smoke outlets of the middle combustion chamber and the upper combustion chamber communicate with the chimney.

Further, the chimney is surrounded by a water jacket. It can further increase the heating area of the water jacket.

Further, the smoke outlet of the middle combustion chamber is provided with a smoke outlet pipe connected to the kang, the upper part of the smoke outlet pipe is connected with the chimney, and an inserting plate and a smoke guide plate are arranged on the smoke outlet pipe. It can change the path of the flue gas. When it is necessary to burn the kang, the smoke goes through the kang, and when it does not need to be heated, it goes through the chimney.

Further, the interlayer between the middle combustion chamber and the upper combustion chamber is a water jacket type interlayer. It can further increase the heating area of the water jacket.

Further, the bottom of the lower combustion chamber is the bottom of the water jacket furnace, on which a lower furnace grate is arranged. It can further increase the heating area of the water jacket.

Further, the middle furnace grate and the lower furnace grate are round furnace grates, and coal rings are arranged on the middle furnace grate and the lower furnace grate.

Furthermore, a ring-shaped air distribution pipe is arranged around the fire passage, and a number of air inlet holes are evenly distributed inside the ring-shaped air distribution pipe. One or both sides of the ring-shaped air distribution pipe are provided with an air inlet pipe connected to the ash storage chamber at the bottom of the lower combustion chamber. It can improve the combustion effect of the upper combustion chamber, improve thermal efficiency,

The using method of the utility model:

1) When adding fuel in the middle combustion chamber: open the burner baffle, the flame burned in the middle will directly touch the bottom of the pot through the burner, which is suitable for short-term cooking, with strong firepower and fast cooking.

2) When adding fuel in the lower combustion chamber: remove the grate from the middle furnace, and open the baffle at the fire port when burning the boiler and cooking water in a large pot at the same time; The crater baffle prevents the flame from going to the first combustion chamber.

3) When adding biomass fuels such as plant stalks, firewood or cow and sheep dung to the lower combustion chamber: take out the coal ring on the lower furnace grate, the combustion chamber has sufficient space, and a lot of fuel can be added at one time.

Compared with the prior art, the utility model has the advantages that:

1) It includes a lower combustion chamber, a middle combustion chamber and an upper combustion chamber, and the middle combustion chamber is narrower than both the upper combustion chamber and the lower combustion chamber. Adding fuel in the middle combustion chamber or in the lower combustion chamber has different functions and effects. The middle combustion chamber is relatively small and close to the upper combustion chamber, which is suitable for cooking with fire for a short period of time, with strong firepower and fast cooking. The space of the lower combustion chamber is relatively large, and a lot of fuel can be added at one time. It is suitable for heating the heating radiator. Adding enough fuel at night before going to bed can ensure that the boiler will not cool overnight.

2) The space of the lower combustion chamber is relatively large, and coal can be used as fuel, and plant straw, firewood or cattle and sheep dung can also be used as fuel.

3) Further, the smoke outlet of the middle combustion chamber is provided with a smoke outlet pipe connected to the heated kang, the upper part of the smoke outlet pipe is connected with the chimney, and an inserting plate and a smoke guide plate are arranged on the smoke outlet pipe. When it is necessary to burn the kang, the smoke goes through the heated kang, and when it is not necessary to burn the kang, the smoke goes through the chimney.
