Description

Directional combustion-supporting air-cooled rotary furnace bar
Technical field:
The present invention relates to a kind of directional combustion-supporting air-cooled rotary furnace bar, this directional combustion-supporting air-cooled rotary furnace bar is mainly used in boiler, the stove and accessory.
Background technology:
At present all adopting the fire grate technology in the boiler plant, is fixed grate and civilian miniature boiler institute generally adopts, and the rotary furnace bar that has is rotary fire grate in fact, though yet there is a kind of rotary furnace bar to cause the fire bars deformed damaged because of furnace temperature is too high, it is inconvenient to use; The fire grate that uses has that the combustion-supporting fuel of blower fan is thin to cause the temperature full combustion of fuel that is unfavorable on the low side in the boiler, can't realize that also second-time burning truly easily causes the environmental pollution wasting of resources.
Summary of the invention:
The present invention proposes in view of the above-mentioned problems, so that a kind of neoteric directional combustion-supporting air-cooled rotary furnace bar to be provided is purpose, and this kind fire bars makes fuel combustion abundant, and the fire bars life-span is long not yielding, be particularly useful for vertical furnace chamber, the higher full combustion of fuel that is easy to of vertical furnace chamber furnace temperature.
To achieve the above object, the present invention adopts following technical proposals.
A kind of directional combustion-supporting air-cooled rotary furnace bar, comprise the fire bars shell, position plate, axis, blower fan is characterized in that tooth or groove are arranged on the fire bars shell, communicate with fire bars shell air compartment in porose on stove tooth or the groove, fire bars shell one end has axle, the inboard of axle is tubular porosely communicate with fire bars shell air compartment and burner hearth air compartment respectively near the place of fire bars, and a sprocket wheel is fixed in the outside or transmission devices such as gear, belt wheel connect with motor, and the other end of fire bars shell passes through the axis connection of axle sleeve or bearing and hollow.The built-in end of axis connects with the part of the close transmission device of internal diameter of fire bars shell by axle sleeve or bearing, and the outer blower fan of the outer end of axis and burner hearth connects.The inboard has the aperture pipeline to connect with the burner hearth air compartment; Porosely between the inboard refractory material of burner hearth air compartment communicate with the burner hearth air compartment, burner hearth bottom has back smoke-box.
Preferably, there are axle sleeve or bearing in the inboard place that connects with axis, the two ends of fire bars shell.
Preferably, there is seal cover in the outside of fire bars.
Preferably, there is the connection shell that communicates with burner hearth air compartment and fire bars shell air compartment the fire bars shell outer end of close transmission device, and there are two seal covers at two ends.
Preferably, position plate and axis are fixed together.
Preferably, position plate is that groove shape opening is towards burner hearth
Preferably, burner hearth one side has well-illuminated observation window.
Preferably, there is filter the observation window inboard.
Description of drawings:
Technical scheme of the present invention and advantage will be described in detail in conjunction with the drawings, in this accompanying drawing:
Fig. 1 is first embodiment of the present invention
The specific embodiment:
Explain the preferred implementation of directional combustion-supporting air-cooled rotary furnace bar of the present invention below in conjunction with accompanying drawing, main in embodiment is that example describes with the rotary furnace bar with air compartment:
Embodiment 1:
As shown in Figure 1, the directional combustion-supporting air-cooled rotary furnace bar of first embodiment of the present invention comprises fire bars shell 19, motor 12, blower fan 13, transmission device 11 blower fan pumps 14, it below burner hearth 1 rotary furnace bar shell 19, tooth 5 is arranged on the fire bars shell 19, porosely on the tooth 5 communicate with air compartment 2, the axle head of fire bars shell 19 connects with motor 12 through transmission device 11, axle head connects with housing warp beam sleeve or bearing 9, there is the little air compartment of a with closure 10 inboard and has pipeline to communicate with the air compartment 2 of burner hearth 1, the other end internal diameter two ends of fire bars shell 19 connect by two axle sleeves or bearing with axis 18, and outer section has seal cover 16, axis 18 is that tubulose is porose through pipeline 15 in the outside; Communicate with burner hearth air compartment 2, the outer end connects with motor 13, blower fan 14, and axis 18 has the directed notch board 8 that is fixed together with axis in the inside of fire bars shell 19, and opening is towards burner hearth, there is refractory material 20 the burner hearth inboard, and furnace enclosure one side has transparent windows 3 built-in filters 4.
According to said structure, because the opening of directed notch board 8 is all the time towards the burner hearth direction, so the fuel combustion in the burner hearth is played combustion-supporting effect, the effect that fire bars shell 19 is played cooling has simultaneously prolonged the distortion that has prevented the fire bars shell service life, motor 12 rotations drive 19 rotations of fire bars shell through transmission device 11,18 of fire bars shell 19 and axis have axle sleeve or bearing 17 so axis 18 and directed notch board 8 can maintain static, at blower fan 13, make under the effect of pump 14 be full of air that certain pressure is arranged in the air compartment 6 of the air compartment 2 of burner hearth 1 and fire bars shell 19 and through the hole or groove blow in the burner hearth 1, strengthened combustion efficiency, falling by fire bars shell 19 rotation, to raise the efficiency and make the boiler stereo burning to become feasible for ash, can effectively decompose nonflammable toxic gas such as dioxin makes waste incineration and generating electricity become non-pollution discharge to be achieved thereby furnace temperature is higher in the burner hearth of stereo burning 1.
Though more than be that example is illustrated to have the built-in directed notch board 8 of rotary furnace bar, directed notch board of the present invention also can be external, also available gear of transmission device or belt wheel drive, blower fan 13, pump 14 also can pipe special lead to the air compartment of burner hearth 1.
Above-described preferred implementation is illustrative and not restrictive the present invention under the situation that does not break away from purport of the present invention and essential characteristic, the present invention can also other modes implements and specializes, scope of the present invention is limited by claim, so the distortion in the claim scope all falls within the scope of the present invention.
