Description

The civil multipurpose furnace

It is the stove and accessory of fuel with the coal that the utility model relates to a kind of.

At present, known is the domestic burners of fuel with the coal, and it is made of the fire grate of body of heater, bell, flue, flue end opening, the annular heat absorption water jacket that is enclosed within furnace gall periphery and the chimney joint of upper of furnace body one side.Must be in adding burner hearth suitable for reading when adding coal, the combustion charcoal produces a large amount of flue gases from the fire door air in the dirty beam camber of emerging under the burner hearth condition of high temperature.The ashes that produce in the coal burning process fall from the slit of fire grate or when making its ashes whereabouts with stove hook hook straight joint crack, and the part ashes spill from the fire door of below and enter air.The bulk slag that sinters in combustion process can't fall from the slit of fire grate, forms thicker slag layer gradually, has reduced burning zone, can't use for a long time continuously.It can only be as heating up water, cook, provide hot water, can't baked goods, and the flue gas heat of the higher temperature of extracting out with chimney does not obtain utilizing simultaneously.

The purpose of this utility model provides a kind of energy baked goods, reclaims flue gas heat, and coal is over-emitting black exhaust not, is convenient to remove thorax bottom slag, collects the civil multipurpose furnace of removing ashes.

The utility model is realized by following measure.

The shell of civil multipurpose furnace is a rectangular casing, and the circular fire door of upper cover plate processing of casing is stamped bell on the fire door.The upper cover plate of casing also is processed with the mouth that the flue gas waste heat recovery device is installed.The front plate top and the middle part of casing are processed with coal filling hole, skimming gate.Coal filling hole is lifted with the movable doorboard of inclination.The tube of skimming at worn-out mouthful of two of stretching in the casing is equipped with at the skimming gate place, and outer nozzle is equipped with door-plate.The bottom of casing front plate is processed with installs the rectangular opening that connects ash bucket, pushes the ash bucket that connects of drawer type in the rectangular opening.Constitute on the end plate connect ash bucket and be processed with equally distributed fresh air inlet, medial surface have one with the relative air quantity control panel that can laterally spur of fresh air inlet on the end plate.The middle and lower part of casing front plate is amesiality to be processed with the door that picks and places baked goods, to the baking oven of baked goods is housed in the casing of answering the door.The tube bank that the flue gas waste heat recovery device in the box cover plate mouth of packing into is communicated with cavity between the inner/outer tube in the two-port on the inner core by inner core, urceolus, transverse weld, be welded on the hush panel of inner core to the annular upper and lower opening between the urceolus, the outlet pipe that communicates with inner chamber and the water inlet pipe that are welded on urceolus upside and downside constitute.The water inlet pipe of flue gas waste heat recovery device is communicated with by the outlet pipe of welding with the annular heat absorption water jacket that is enclosed within furnace gall periphery.The hypomere of flue gas waste heat recovery device is in the rectangular casing, and epimere is stretched on casing, and upper port is equipped with the cone-shaped hood that end mouth is a rectangle, and the chimney straight connector is installed on the top of cone-shaped hood.Between the bottom side of flue gas waste heat recovery device and the annular heat absorption water jacket passage that stove fire flame is turned back to the baking oven upper cavity is arranged.It between the bottom of flue gas waste heat recovery device and the food baking oven flame chamber of turning back.Flue is the cylindrical body that the big employing refractory material of handle mouth suitable for reading is made, an example suitable for reading have one with the rectangular box front plate on the relative breach of coal filling hole, the Di Kouchu of the same side have one with the rectangular box front plate on the relative breach of skimming gate.The periphery of flue is with the annular heat absorption water jacket of bringing water pipe and outlet pipe into.There is the supporting plate of holding flue of a band center hole bottom of boiler clothing, and supporting plate is to the gripper shoe that setting is arranged between the rectangular box base plate.The below of flue supporting plate is equipped with the crossbeam of crossing over center hole, and crossbeam is fixed by bolts to the bottom of flue supporting plate by the bolt hole at two ends.The middle part of crossbeam is processed with the axis hole that fire grate is installed, and axle is installed in the hole.Fire grate is circular, be contained on the crossbeam under the flue supporting plate, be processed with central shaft hole and eccentric pivot hole, central shaft hole is relative with the axis hole at crossbeam middle part, by axle fire grate is seated on the crossbeam, the eccentric orfice place is connected with pull bar by axle, by the pulling pull bar fire grate is come and gone among a small circle and rotates, and the ashes that cause collection to be stored in burner hearth bottom drop to drawer type and connect in the ash bucket.

Advantage and effect:

Civil multipurpose furnace described in the utility model.The door-plate that only need open inclination during coal gets final product, and flue gas is pulled out outdoorly by chimney under the effect of chimney draft, and the coal filling hole place does not have flue gas emerges.The thinner ashes that accumulate on the fire grate only need come and go the pulling pull bar, and fire grate is positive and negative rotation, and ashes just drop to drawer type and connect in the ash bucket, will connect to outwell after ash bucket goes out.Accumulate in the slag that can't fall on the fire grate, only need open the door of the tube of skimming, the stove hook is stretched into burner hearth, slag is grilled in the slag tube, extract the tube of skimming then out slag is outwelled.The flame that produces during burning enters the cavity that baking oven gets final product baking oven top from suitable for reading the turning back of flue, and baking oven is heated, and the baking oven of at this moment food being packed into can toast.The cold water that enters annular heat absorption water jacket is entered waste-heat recoverer from outlet pipe after the heating for the first time, enter the heat transferred that absorbs flue gas in the tube bank and the water in the cavity by inner core and tube bank, the outlet pipe of hot water on the surplus recover of flue gas is connected with the heating installation bag by the road, after heating installation bag heat dissipation capacity, enter annular heat absorption water jacket, form closed circulation.
