Continuous changes are also possible.

Description

Swirl Angle Adjustable Flame Stabilizer

technical field

The utility model relates to an air distribution device of a combustion head of a burner, in particular to a flame stabilizer with an adjustable swirl angle.

Background technique

At present, the flame stabilizers of the combustion head of light oil burners are mostly disc-shaped, and different disc shapes are provided with different swirl slot openings, and different swirl slot openings determine different swirl angles. However, the flame stabilizer needs to be shut down and disassembled when it is replaced. It is very inconvenient to change the swirl angle of the air distributor, and the swirl angle cannot be continuously changed.

Contents of the invention

The purpose of this utility model is to provide a flame stabilizer with an adjustable swirl angle for the above-mentioned defects in the prior art. Through the connection of rack and pinion, the continuous change of the swirl angle of the air distribution of the flame stabilizer can be realized.

The technical solution is: the inner sleeve, the outer sleeve and the combustion tube are fixed together, the inner sleeve is provided with multiple sets of blades, each blade is fixedly connected by a blade fixing rod, and the rotating blade fixing rod The column is used to adjust the angle of the blade. Each blade fixing rod is connected to a pinion at the outer end, and multiple pinions are meshed with a ring rack; a blade positioning ring is provided at the inner end of the blade fixing rod to fix The vane is fixed to the rod column; the outer side of the inner sleeve is provided with an outer sleeve to fix the ring rack and limit the axial displacement of the pinion.

The above-mentioned outer sleeve is provided with rack positioning threaded holes, swirl angle adjustment holes) and outer sleeve positioning threaded holes.

The above-mentioned blades are provided with ten groups.

The beneficial effect of the utility model is: through the rack and pinion connection, the continuous change of the swirl angle of the air distribution device of the flame stabilizer can be realized, which avoids the inconvenience of stopping and disassembling the flame stabilizer when it is replaced, and makes the swirl angle of the air distribution device It is very convenient to change, and continuous change can also be realized.

Detailed ways

In conjunction with accompanying drawings 1 and 2, the utility model is further described:

The utility model comprises that the inner sleeve 4, the outer sleeve 7 and the combustion tube 8 are fixed together, and the swirl area part of the original disk-shaped flame stabilizer is changed into ten blades 2, and each blade 2 is composed of one blade The fixed rods 1 are fixedly connected, and the rotating blade fixed rods 1 are used to adjust the angle of the blades. Each blade fixed rod 1 is connected to a pinion 3 at the outer end, and multiple pinions 3 are meshed with an annular rack 5 to rotate The rack and pinion will rotate accordingly, thereby driving the pole to rotate, and finally realize the continuous change of the angle of the swirl blade; the inner end of the blade fixing pole 1 is provided with a blade positioning ring 6 to fix the blade fixing pole 1 ; The outside of the inner sleeve 4 is provided with an outer sleeve 7, which is used to fix the ring rack 5 and limit the axial displacement of the pinion 3.

Wherein, the outer sleeve 7 is provided with a rack positioning screw hole 8-1, a swirl angle adjustment hole 8-2 and an outer sleeve positioning screw hole 8-3.

The other side of the annular rack 5 is distributed with a partial tooth shape, and the meshing of the screwdriver for adjusting the swirl angle can drive the rack to rotate, and then drive the pinion to rotate to change the swirl angle. It avoids the inconvenience that the flame stabilizer needs to be shut down and disassembled when it is replaced, and it is very convenient to change the swirl angle of the air distributor, and it can also realize continuous change.
