Abstract
The utility model discloses a straw particle fuel screw type combustor which comprises a combustor body, an electric igniter and a combustion air blower. The straw particle fuel screw type combustor is characterized in that the combustor is rectangular, venting holes are uniformly arranged in the bottom of the combustor, a spiral driving lever is assembled along the length direction of the combustor and is connected with an ash pushing motor, an ash outlet is arranged in the outer end of the combustor, and an air blast outlet of the combustion air blower is positioned under the venting holes in the bottom of the combustor. The straw particle fuel screw type combustor disclosed by the utility model has the advantages that the ash obtained after combustion can be continuously naturally discharged without blocking the venting holes; the combustion air blast is carried out on the bottom of a combustion disk, no parts block the wind, so that fuel is combusted more completely, and little ash exists; and the straw particle fuel screw type combustor is suitable for a low-class straw particle fuel, and no ash is remained in the spiral combustion disk. The spiral combustion disk can realize automation combustion of the low-class straw particle fuel, and can ensure that the low-class straw particle fuel is high in combustion rate; and according to used heat loads of users, a plurality of spiral combustion disks can be simultaneously installed, so that demands of the users are met, and the structure is simplified.
Description
Technical field
The utility model relates to a kind of burner, the spiral burner of particularly a kind of stalk granular fuel.
Background technology
Stalk granular fuel is that national policy is helped the environmental protection project of promoting in recent years.This fuel does not produce harmful burnt gas, not air pollution, and ashes also contain materials such as phosphorus, potassium, can make the fertilizer auxiliary material.At present, having occurred civilian small-sized heating furnace on the market, is fuel with the stalk particle, and structure mainly is made up of material storing box and combustion furnace two parts.The material storing box middle and lower part has spiral driving lever, blast pipe to communicate with combustion furnace.The deficiency of this small-sized heating furnace is: fuel combustion is abundant inadequately; Ashes are more, develop a kind of straw granular fuel combustion furnace afterwards, are provided with electric igniter at the tray for combustion inwall; The rotation shifting block vertically is set on the chassis in tray for combustion, and shifting block links to each other with the shifting block motor through a pair of bevel gear.Fuel can fully burn, and ashes are few.And, make the particulate material ashes after the burning be milled into powder because of the distance at the bottom of shifting block and the tray for combustion is little.But this kind combustion furnace remains in deficiency: the ashes after the burning can not be discharged continuously naturally, and ashes are prone to block air vent in tray for combustion, influence the abundant burning of fuel.Combustion blower is positioned at the bottom of combustion furnace simultaneously, and is far away apart from the bottom of tray for combustion, gets into the abatement of wind of air vent, and the transmission bevel gear of shifting block is positioned at the top of blast orifice simultaneously, blocks wind-force.The structure more complicated.
Summary of the invention
The purpose of the utility model provides the spiral burner of a kind of stalk granular fuel, and the ashes after the burning can be discharged continuously naturally, can not block air vent; Air blast burn simultaneously in the bottom of tray for combustion, and no parts block wind-force, make fuel combustion abundant; Ashes are few, designs simplification.
The purpose of the utility model realizes through following technical scheme: it comprises burner, electric igniter and combustion blower; It is characterized in that: burner is rectangle; Air vent evenly is set in the bottom, and along burner length direction assembling spiral driving lever, the spiral driving lever connects propelling movement ashes motor; The burner outer end is provided with the ashes outlet; The air blast of combustion blower outlet be positioned at the burner bottom vents below.
The utility model has the advantages that: 1, the ashes after the burning can be discharged continuously naturally, can not block air vent, and the air blast of burning simultaneously is in the bottom of tray for combustion, and no parts block wind-force, make fuel combustion abundant, and ashes are few; 2, be applicable to rudimentary stalk granular fuel (comprising B, C grade stalk granular fuel), ashes do not remain in spiral tray for combustion the inside.So use spiral tray for combustion, can realize B, C grade stalk granular fuel automation burning.3, can make rudimentary stalk granular fuel realize high combustion rate.4, according to user's use thermic load, a plurality of spiral tray for combustions can be installed simultaneously, satisfy user's demand with this.5, designs simplification.
Description of drawings
Fig. 1 is the sketch map that the utility model burner and material storing box and combustion furnace fit together.
Fig. 2 is the vertical view of the utility model burner.
The specific embodiment
See Fig. 1,2; The concrete structure of the utility model is following: burner 10 is rectangle; Both sides are the insulation wall with the inner, and top is open state, and air vent 15 evenly is set in the bottom; Through bearing 11 assembling spiral driving levers 14, spiral driving lever 14 connects propelling movement ashes motor 3 along the burner length direction; Burner 10 outer ends are provided with ashes outlet 11-1; The firing tip of electric igniter 2 is positioned at burner 10 inner bottoms, and combustion blower 1 connects the air blast outlet through ajutage 17, the air blast outlet be positioned at burner 10 bottom vents 15 below.Lower room outer end in the burner bottom is provided with except that little ashes door 12.
Operation principle:
See Fig. 1, during use, the utility model burner and material storing box 7 are fitted together with combustion furnace that sets of burners of the present invention is contained in the bottom of combustion furnace, the top of combustion furnace is provided with chimney 8, and the bottom is provided with transparent doors 9.Material storing box 7 bottoms that stalk granular fuel 6 is housed are provided with tremie pipe 16, and tremie pipe 16 outlets are positioned at burner 10 inside fronts.Be provided with the spiral driving lever 5 that feeding motor 4 drives in material storing box 7 bottoms.Electric igniter 2 external control circuit plate (not shown)s realize igniting automatically, and ability timing return and startup simultaneously push 3 operations of ashes motor.Can realize starting at a distance, stopping working etc.Can master control or multiple spot control be set according to the combustion furnace scope of application.
In equipment when operation,, stalk granular fuel 6 enters into burner 10 through the tremie pipe 16 of lower directions, accumulate a certain amount of after, light stalk granular fuel through electric igniter 2, in the combustion chamber, blow through uniform air vent 15 with combustion blower 1.
Through behind the certain hour, spiral driving lever 14 beginnings of burner 10 the insides are with the certain speed rotation, and stalk granular fuel burns away simultaneously.
Granular fuel is after burning a period of time, and the spiral driving lever 14 in the burner 10 outwards pushes the ashes after the completing combustion in the burner 13 with the certain speed rotation continuously uniformly, and 11-1 discharges from the ashes outlet.
