Description

The coal stove of quantity-adjustable

The utility model belongs to coal dust ball stove, relates in particular to the coal dust ball stove that can regulate intake.

Family and restaurant coal dust ball stove used in everyday mostly is cast iron, steel plate or ceramic making, the coal stove fire door of these unlike material manufacturings all is opened in the sidewall of furnace bottom, fire door laterally communicates with furnace bottom, and furnace bottom is the air channel, when stove is banked up a fire, fire door is closed with a female cap, this stove, the wind that enters burner hearth from fire door can not directly be gathered in the burner hearth center, and coal briquette can not fully burn, it is more to produce the carbon monoxide pernicious gas, the thermal efficiency is low, and fire door is not that standard-sized sheet is exactly a complete shut-down in addition, can not open the minor adjustment air quantity greatly to open, be unfavorable for being sparing in the use of coal, fire door and fire door are non-machined surface, are not closed completely, and have gas leak phenomenon, the weak effect of banking up a fire, slag also must be drawn by staff.

The purpose of this utility model provides a kind of coal stove of quantity-adjustable, this stove wind-force is gathered in the furnace chamber center, coal briquette can fully burn, reduce CO emission, thermal efficiency height is sparing in the use of coal, fire door can be regulated the size of intake, fire door is closed the back good airproof performance, and it is effective to bank up a fire, and door opened back slag falls automatically.

Take following technical scheme for realizing this purpose, the coal stove of quantity-adjustable, comprise bonnet, body of heater and be positioned at the stone or metal plate for standing a stove on as a precaution against fire of body of heater below has blast pipe below stone or metal plate for standing a stove on as a precaution against fire, from blast pipe to the stove item, its internal diameter changes from small to big and is divergent contour, fire door is arranged at the bottom at blast pipe, and fire door can rotate to an angle around the fixed axis that is fixed on blast pipe one side, and fixed axis is provided with the spring that is pressed on the fire door.

Blast pipe is tubaeform, and it and the same axis of burner hearth are suitable for reading big, young down, end opening is an air inlet, and its diameter is greater than the coal briquette external diameter, air inlet end face and be airtight smooth finish surface with the fire door contact-making surface, fixed axis is located at air inlet end face one side, and opposite side is provided with the fire door rotation set screw.

Because air inlet of the present utility model and burner hearth have same axis, therefore wind-force is directly aimed at the burner hearth center, carbon monoxide emission is few, coal briquette can fully burn, thermal efficiency height, fire door can turn an angle the size that changes air inlet in order to regulate intake around fixed axis, and the contact-making surface of fire door and intake mouth is airtight smooth finish surface, and on fixed axis, be provided with spring, when fire door was closed, gas leakage was few, and it is effective to bank up a fire, from the blast pipe to the furnace roof, its internal diameter changes from small to big and is divergent contour, the stove good heat insulating, and this furnace construction is reasonable, result of use is good, residue-discharge convenience.

The utility model is described in further detail below in conjunction with drawings and Examples.
