Description

Efficient energy-saving furnace

Technical field

The utility model relates to a kind of domestic stove, particularly a kind of efficient energy-saving furnace.

Background technology

Domestic existing faggot stove generally is made up of table, burner hearth and furnace shell, in use exist many with bavin, fuel availability is low, heat-energy losses is big, cook, heat up water, cooking speed is slow, the high easily scald people of furnace wall temperature, once reinforced burning time is short and structural design is unreasonable, the shortcoming of inconvenience maintenance.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of efficient energy-saving furnace of reasonable in design, has overcome the defective of existing faggot stove, and firing rate is few, fuel availability is high, heat-energy losses is little.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of efficient energy-saving furnace, comprise table and the burner hearth that is installed on the table, burner hearth is with furnace shell outward, the furnace shell upper end is installed with boiler face, burner hearth is by the furnace wall that connects successively from bottom to top, furnace roof and fire door are formed, inside, furnace wall is provided with at the bottom of the liftable ash-removing stove that is installed on the elevating mechanism, be provided with a cavity that communicates with air inlet on the furnace shell at the bottom of the liftable ash-removing stove and between the table, be placed with grey box in the cavity, the furnace shell on top is provided with the charge door of band fire door at the bottom of the liftable ash-removing stove, charge door passes the furnace wall and communicates with burner hearth inside, constitute a ring-shaped air chamber that communicates with charge door between furnace roof and the furnace shell, flue communicates with ring-shaped air chamber, and removable cover is installed on the boiler face.

In the elevating mechanism, the connecting rod lower end of passing table is connected with the lift adjustment frame, and the connecting rod upper end is connected with at the bottom of the liftable ash-removing stove.

In the lift adjustment frame, support body one side is connected with placing the handle in the vertical chute of table, and the support body opposite side is connected with balancing pole in placing the vertical chute of table by the collar.

Be provided with boiler clothing between furnace shell and the furnace wall.

It at the bottom of the liftable ash-removing stove furnace bottom of band grate.

Fire door is eccentric fire door, is sleeved on the neck of furnace roof with the burner hearth base plate of eccentric crater, and fire-stop ring is installed on burner hearth base plate top, and the fire door upper end is equipped with active ring and cover plate.

The exhanst gas outlet switch is installed on the flue.

The efficient energy-saving furnace that the utility model provides, beneficial effect is as follows: 1, because at the bottom of the liftable ash-removing stove that is installed on the elevating mechanism is established in inside, furnace wall, place fuel at the bottom of the liftable ash-removing stove, but the height at the bottom of the big or small up-down adjustment liftable ash-removing stove of based on fuel flame mechanism and combustion flame, shortened the distance between combustion flame and the crater, firing rate is few, flame is high, firepower is strong; Fuel availability height, heat-energy losses are little; Ring-shaped air chamber between furnace roof and the furnace shell has overcome the shortcoming that existing faggot stove does not have special air chamber, has prolonged the currency of flue gas in stove, has reduced the concentration of flue gas, has improved IAQ, has reduced fume amount, clean hygiene.

2, the effect of insulation has been played in the design of boiler clothing, both made the fuel in the burner hearth under the higher environment of temperature, rapid decomposition combustion preserve heat, reduce heat and distribute the heat-energy losses that causes, can prevent from again to cause the too high easy scald people's of casing temperature situation to take place because of furnace shell directly contacts with burner hearth, safe.

3, eccentric fire door makes that the flame of fuel generation is bent, bottom cooker is not direct heat transfer, has disconnected the direct heat transfer point, has further reduced heat-energy losses, the contact area and the time of contact of flame and cooker bottom have been increased simultaneously, the temperature of the cooker bottom that effectively raise.

4, balancing pole cooperates the design of the collar to make the lift adjustment frame when upper and lower activity in the lift adjustment frame, can move adjusting simultaneously in the horizontal direction, avoided at the bottom of the liftable ash-removing stove and the friction between the furnace wall, guaranteed at the bottom of the liftable ash-removing stove can be in inside, furnace wall smoothly, upper and lower motion apace.

5, the exhanst gas outlet switch fits into the air port and can play the effect of regulating the firepower size, has adapted to the demand of different cookers.

6, reinforced convenient: as, constantly to append fuel and get final product from charge door if need or not take off cooker for a long time for fire.

7, the utility model thermal efficiency height, through combustion test, the firing rate of every boiled 5 kilograms of boiling water (initial water temperature 13-16 ℃) is: 1) careless class A fuel A is 1.8 kilograms; 2) the stalk class A fuel A is 0.9 kilogram; 3) wooden class A fuel A is 0.7 kilogram; Than existing faggot stove fuel saving more than 30%, and burning time is long, and the once reinforced sustainable burning in back need not be fed in raw material more than 90 minutes.
