Description

Coal and firewood dual-purpose energy-saving cooking bath furnace

technical field

The utility model relates to a cooking bath furnace, in particular to an energy-saving dual-purpose cooking bath furnace which can use both coal and firewood.

Background technique

As we all know, the cooking bath furnace is easy to operate, economical and affordable. Therefore, cooking and bathing stoves have been widely used in the vast urban and rural areas of my country, especially in the homes of rural residents. People continue to improve the technology of cooking bath furnaces, and the products of cooking bath furnaces are constantly updated, from ordinary steel plate furnaces, enamel furnaces, cold galvanized furnaces, hot dip galvanized furnaces to stainless steel furnaces, aluminum alloy furnaces, etc. There are also those that use firewood alone, with a variety of specifications and forms, but they still have some problems: First, in the vast rural areas of our country, due to the abundance of coal and cheap firewood resources, according to seasonal changes and usage conditions, Different, in order to save fuel costs, the majority of residents generally use coal in winter, and want to use firewood in summer, so as to achieve the purpose of saving fuel costs. Second, due to the fixed setting of the grate of the existing cooking and bathing furnace, the height of the fuel combustion area in the furnace is relatively constant. When the damper is open and in use, the temperature of the water in the hot water tank around the furnace will rise, but the temperature rise is not fast enough. Therefore, the relatively constant height of the combustion area of the cooking bath furnace is not conducive to The water in the hot water tank heats up quickly; moreover, in order to ensure that the distance between the firewood and the furnace mouth should not be too far, so as not to affect the cooking effect, it can only design the wood-burning cooking and bathing furnace as a horizontal type. Pushing the firewood, the smoke exhaust effect of this horizontal cooking and bathing furnace is not very good, and the ash discharge is inconvenient.

Utility model content

Aiming at the above-mentioned problems existing in the use of the cooking bath furnace in the prior art, the utility model provides a device that can adjust the upper and lower positions of the furnace core and the grate according to the amount of hot water and seasonal changes, so as to control the heating rate of the water. It can burn both coal and firewood. It is a practical and environmentally friendly coal and firewood dual-purpose energy-saving cooking and bath stove.

The technical solution adopted by the utility model to solve the technical problems is: the dual-purpose energy-saving cooking and bath furnace for coal and firewood includes a stove base, a heat preservation body, a water tank, a furnace frame and a furnace core, and the water tank is located inside the heat preservation body, on the upper part of the water tank The hot water valve for water outlet and the cold water valve for water inlet are respectively provided at the bottom and the bottom part, and a cylindrical tube integrally connected with the water tank is provided in the water tank, and the upper and lower ends of the cylindrical tube protrude to the top and bottom of the water tank respectively A side air inlet pipe is arranged on the side of the lower end of the cylindrical pipe, an upper air inlet pipe passing through the bottom of the water tank is arranged on the upper end of the cylindrical pipe, and a lower air inlet pipe is arranged on the lower end of the cylindrical pipe. The upper air inlet pipe and the lower air inlet pipe One end of the pipe is connected with one end of the lower exhaust pipe protruding out of the insulation body and the air outlet of the blower through a multi-head spherical valve. A lifting mechanism that can adjust the height of the grate inside the cylindrical tube is installed on the furnace frame. There is a movable furnace core, and an annular flue communicated with the upper smoke exhaust pipe is arranged between the furnace platform and the heat preservation body.

The working process of the present utility model is:

1. Use coal as the fuel. When the cooking bath furnace is in the standby state, cover the furnace cover. According to the amount of hot water used, properly open the side air inlet pipe, and use the lifting mechanism to adjust the upper and lower positions of the furnace core. When needed When using a large amount of hot water, lower the furnace core to the lowest position to increase the area of the coal-fired upper combustion zone. The waste heat in the combustion zone is transferred to the water tank through the cylindrical tube, and the hot flue gas passes through the upper air inlet pipe located in the water tank to exhaust the smoke. The temperature of the air cools down, while the water temperature rises, and by controlling the multi-head spherical valve, the upper air inlet pipe communicates with the lower smoke exhaust pipe, and the smoke is discharged from the lower smoke exhaust pipe.

2. Coal is used as the fuel. When the cooking bath furnace is in use, remove the furnace cover, put on the cooking utensils, open all the side air inlet pipes, and use the lifting mechanism to adjust the furnace core to rise to the highest position, and control the multi-head spherical valve. Make the upper air inlet pipe communicate with the lower smoke exhaust pipe, the flue gas is discharged from the annular flue on the furnace surface and the upper smoke exhaust pipe, and the lower smoke exhaust pipe supplies oxygen to the combustion zone through the upper air inlet pipe to make the coal combustion fully combustion,

3. Use firewood as fuel. When the cooking and bathing furnace is in use, remove the furnace cover and furnace core, close the side air inlet pipe, place firewood in the furnace core, ignite firewood, put cooking utensils, and control the multi-head spherical valve to make The air outlet of the fan is connected with the upper air inlet pipe and the lower air inlet pipe at the same time. When the fan is started, the wind enters the cylindrical pipe from top to bottom to make the firewood burn vigorously. The water heats up, and the flue gas is discharged from the annular flue on the furnace surface and the upper flue pipe at the same time.

4. Use firewood as fuel. When the cooking and bathing furnace is not in use, turn off the fan, cover the furnace cover, properly open the side air inlet pipe, control the multi-head spherical valve, make the upper air inlet pipe communicate with the lower smoke exhaust pipe, and make the waste heat of firewood burning Passed to the water tank, the hot flue gas is cooled through the upper air inlet pipe and then discharged from the lower exhaust pipe, making full use of the waste heat and keeping the room clean and hygienic. If all the inlets are closed, the remaining burned firewood can be turned into charcoal. Reserve for later use.

Compared with the existing cooking bath furnace, the utility model has the following characteristics:

1. Since the grate is supported on the lifting mechanism that can adjust the height of the grate outside the furnace, the grate and the furnace core can move up and down. By controlling the upper and lower positions of the furnace core and the furnace grate, the temperature of the water in the water tank can be adjusted. Whether to use coal or firewood, the height of the furnace core and the grate can be adjusted reasonably according to the season and the amount of hot water used, so that the speed of the water temperature rise in the water tank can be controlled, which brings great convenience to people.

2. Since the water tank is equipped with an upper air inlet pipe that can not only ventilate but also exhaust smoke, when the hot smoke passes through the upper air inlet pipe in the water tank, the heat of the hot smoke can be transferred to the water in the water tank, which can speed up the flow of water. The temperature rises and at the same time reduces the temperature of the flue gas, which is conducive to the rapid discharge of the flue gas and environmental protection.

3. Adopt the vertical structure in which the grate and the furnace core can be lifted up and down, so that the dust is discharged from the side air duct in an orderly manner from top to bottom, which improves the working environment.

4. According to seasonal changes and local fuel types, coal and firewood can be used alone to make full use of local fuel resources, thereby reducing fuel costs.

5. The utility model has the advantages of compact structure, convenient operation and strong durability, and is widely applicable to rural household use.
