Abstract
The utility model provides a regulating rod device with rotating vanes, which is characterized by comprising a regulating rod fixing device fixed in a powder coal burner and a regulating rod sealing device fixed on a powder coal pipeline on the upper portion of the powder coal burner. The rear portion of a connection rod of a regulating rod is arranged in the regulating rod sealing device, the head portion of the connection rod of the regulating rod penetrates through the regulating rod fixing device to be connected with a head cylinder body of the regulating rod, and at least one spiral vane of the regulating rod is arranged on the outer surface of the head cylinder body of the regulating rod. The regulating rod device has the advantages that the regulating rod device with the rotating vanes can be suitable for burning regulating effect of more powder coal nozzles (including burners with rotational flow effect and burners without the rotational flow effect), adjustment of rotational flow strength is various and refined, and air flow evenness can be controlled more effectively. Simultaneously, the regulating rod device with the rotating vanes is simple and reasonable in structure.
Description
Technical field
The utility model relates to a kind of adjusting rod device, belongs to coal powder boiler combustion adjusting device field.
Background technology
The coal dust at the coal nozzle place of burner and a wind mixture often need be regulated in pulverized-coal fired boiler, and the adjusting form is very various.In traditional " W " flame pulverized-coal fired boiler; Burner often adopts the middle form that installs adjusting rod additional of whirlwind tube, and adjusting rod head (burner coal nozzle place) is installed some blades, in the actual motion; Through the position of regulating nozzle place adjusting rod and then spin intensity and the uniform properties of controlling breeze airflow; The further mixability of control breeze airflow and hot secondary wind, and burning ignition point reaches the effect of regulating combustibility.
This common adjusting rod device applicable scope is narrow, often only in whirlwind tube burner, uses, simultaneously often because the contraction of whirlwind tube head causes breeze airflow speed too high to problems such as adjusting rod head erosive wear are serious.Finally cause results such as decline of adjusting rod adjusting function or adjusting rod damage.
Summary of the invention
The purpose of the utility model provides a kind of novel adjusting rod device, can adapt to the burning regulating action of more coal nozzle, optimizes the contour structures of adjusting rod simultaneously, makes its structure more reasonable.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of adjusting rod device that has rotating vane; It is characterized in that: comprise being fixed on the inner adjusting rod fixture of coal burner and being fixed on the adjusting rod sealing device on the pulverized coal channel of coal burner top; The afterbody of adjusting rod connecting rod is located in the adjusting rod sealing device; Its head passes the adjusting rod fixture and links to each other with adjusting rod head cylindrical shell, on the outer surface of adjusting rod head cylindrical shell, is provided with a slice adjusting rod rotation direction blade at least.
Further, the afterbody of said adjusting rod connecting rod is located in said adjusting rod sealing device through positioner.
Said adjusting rod rotation direction blade is at least two, and is distributed on the outer surface of said adjusting rod head cylindrical shell.
Said adjusting rod connecting rod is adjustable positions in said adjusting rod sealing device and said adjusting rod fixture.
The rotation direction angle of said adjusting rod rotation direction blade is the 0-90 degree.
The utility model has the advantages that and adopt this adjusting rod device that has rotating vane; The burning regulating action (include the burner of cyclonic action and do not have the burner of cyclonic action) that can adapt to more coal nozzle; More various and the refinement of the adjusting of swirl strength, more effective to the control of breeze airflow uniformity.Simultaneously, the structure of this adjusting rod device that has a rotating vane is simple more, rationally.

The specific embodiment
For making the utility model more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
Embodiment 1
As shown in Figure 1, be a kind of structural representation that has the adjusting rod device of rotating vane.The described adjusting rod device that has rotating vane is by adjusting rod connecting rod 1, adjusting rod fixture 2, and adjusting rod head cylindrical shell 3, adjusting rod rotation direction blade 4, adjusting rod sealing device 5 and positioner 6 are formed.Wherein adjusting rod fixture 2 is fixed on coal burner 7 inside; Adjusting rod sealing device 5 is fixed on the pulverized coal channel 8 on coal dust firing top; Adjusting rod connecting rod 1 head links to each other with adjusting rod head cylindrical shell 3; Adjusting rod rotation direction blade 4 is evenly distributed on the outer surface of adjusting rod head cylindrical shell 3, the quantity n of the layout of adjusting rod rotation direction blade 4 (n=3) wherein, rotation direction angle θ (θ=21 °); And adjusting rod connecting rod 1 rear portion is fixed in the adjusting rod sealing device 5, finally confirms the position through the location of positioner 6 on adjusting rod sealing device 5.
This adjusting rod device that has a rotating vane is through moving up and down at the inner vertical direction of coal burner 7; Regulate rotating vane in the position at coal burner 7 head nozzle places, and the spin intensity of control breeze airflow and the effect that uniform properties reaches overheavy firing.
As shown in Figure 2, be a kind of structural representation that has the adjusting rod device of rotating vane.The described adjusting rod device that has rotating vane is by adjusting rod connecting rod 1, adjusting rod fixture 2, and adjusting rod head cylindrical shell 3, adjusting rod rotation direction blade 4, adjusting rod sealing device 5 and positioner 6 are formed.Wherein adjusting rod fixture 2 is fixed on coal burner 7 inside; Adjusting rod sealing device 5 is fixed on the pulverized coal channel 8 on coal dust firing top; Adjusting rod connecting rod 1 head links to each other with adjusting rod head cylindrical shell 3; Adjusting rod rotation direction blade 4 is evenly distributed on the outer surface of adjusting rod head cylindrical shell 3, the quantity n of the layout of adjusting rod rotation direction blade 4 (n=4) wherein, rotation direction angle θ (θ=15 °); And adjusting rod connecting rod 1 rear portion is fixed in the adjusting rod sealing device 5, finally confirms the position through the location of positioner 6 on adjusting rod sealing device 5.
This adjusting rod device that has a rotating vane is through moving up and down at the inner vertical direction of coal burner 7; Regulate rotating vane in the position at coal burner 7 head nozzle places, and the spin intensity of control breeze airflow and the effect that uniform properties reaches overheavy firing.
