Description
Technical field
This utility model belongs to heat resource equipment, particularly to a kind of spiral coal powder burner secondary wind adjustment of blade angle
Device.
Background technology
The air inlet of spiral coal powder burner divides two kinds, and a kind of is the First air in air inlet end face centre, and another kind is
At the secondary wind of air inlet end face circumference, the air needed for aftercombustion.At present, domestic also do not have one directly at spiral-flow type coal dust
The circumference of burner's air inlet end face directly regulates the device of secondary wind blade angle, owing to blade angle is fixing,
So that the angle of spiral of secondary wind is also fixing, do not change with the difference of coal, thus have impact on breeze airflow
Being sufficiently mixed of secondary wind air-flow entered with circumference, it is impossible to reach best combustion effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, it is provided that a kind of simple in construction, it is simple to use, it is possible to reach
Spiral coal powder burner secondary wind adjustment of blade angle device to best combustion effect.
This utility model solves technical problem and the technical scheme is that spiral coal powder burner secondary wind blade angle
Adjusting means includes secondary wind urceolus, secondary wind inner core, adjustment barrel inner core, adjustment barrel urceolus, blade, burner end plate, spiral shell
Female, spring washer, is characterized in that two supporting legs are one group, and often two supporting leg one end of group are welded on the end face of burner end plate
On, each two supporting leg other end one fixed plate of welding, between fixed plate and burner end plate, activity installs a regulation spiral shell
Bolt, on the regulation bolt of fixed plate arranged on left and right sides, the threaded nut of difference, is respectively provided with bullet between nut and fixed plate
Spring packing ring, on the left of regulation bolt, connecting bolt termination fixed plate is fixed in termination, and bolt end fixed plate side is fixing connects regulation
Cylinder inner core, opposite side is fixing connects adjustment barrel urceolus, and adjustment barrel urceolus is provided with adjustment barrel urceolus skewed slot, adjustment barrel inner core sets
Having adjustment barrel inner core skewed slot, adjustment barrel inner core skewed slot is identical with adjustment barrel urceolus skewed slot shape, in secondary wind urceolus and secondary wind
Equipped with multiple blades between Tong, vane nose is fixing connects blade front axle, and the two ends of blade front axle are installed on outside secondary wind respectively
In cylinder and the corresponding hole of secondary wind inner core, the rear end of blade is fixedly connected on blade rear axle, and the two ends of blade rear axle exist respectively
Adjustment barrel inner core skewed slot and adjustment barrel urceolus skewed slot slide.
The beneficial effects of the utility model are: the letter of spiral coal powder burner secondary wind adjustment of blade angle apparatus structure
Single, easy to use, it is possible to according to the angle of the different adjustment secondary wind blade of coal, thus to change the spiral shell of secondary air inlet air-flow
Spin line lift angle, the secondary wind air-flow making breeze airflow and circumference enter is sufficiently mixed, and reaches best combustion effect.

Detailed description of the invention
Embodiment, referring to the drawings 1,2, two supporting legs 10 of spiral coal powder burner secondary wind adjustment of blade angle device
It is one group, the most uniform fixing equipped with six groups on the right side of burner end plate 9, often two supporting leg 10 one end welding of group
On the right side of burner end plate 9, the other end one fixed plate 11 of welding of each two supporting leg 10, fixed plate 11 and burning
Between device end plate 9, activity installs a regulation bolt 12, and on the regulation bolt 12 of fixed plate 11 arranged on left and right sides, screw thread connects respectively
Connecing a nut 14, equipped with spring washer 13 between nut 14 and fixed plate 11, on the left of regulation bolt 12, termination is fixing connects spiral shell
Bolt termination fixed plate 15.Bolt end fixed plate 15 side is fixing connects adjustment barrel inner core 3, and opposite side is fixing to be connected outside adjustment barrel
Cylinder 7, adjustment barrel urceolus 7 is provided with adjustment barrel urceolus skewed slot 8, and adjustment barrel inner core 3 is provided with adjustment barrel inner core skewed slot 16, regulation
Cylinder urceolus skewed slot 8 is identical with adjustment barrel inner core skewed slot 16 shape.Equipped with multiple between secondary wind urceolus 1 and secondary wind inner core 2
Blade 5, blade 5 front end connects blade front axle 4, and the activity of wearing respectively of the two ends of blade front axle 4 is contained in secondary wind urceolus 1 and secondary wind
In the corresponding hole of inner core 2, the rear end of blade 5 is fixedly connected on blade rear axle 6, and the two ends of blade rear axle 6 are respectively in adjustment barrel
The skewed slot 16 of inner core and adjustment barrel urceolus skewed slot 8 slide.
The operation principle of spiral coal powder burner secondary wind adjustment of blade angle device is: by adjusting nut 14, make
Regulation bolt 12 moves forward and backward in the hole of fixed plate 11 vertically, and regulation bolt 12 drives bolt head fixed plate 15, bolt head
Fixed plate 15 drives adjustment barrel urceolus skewed slot 8 and adjustment barrel inner core skewed slot 16 to move forward and backward, and blade rear axle 6 is then forced in tune
Joint cylinder urceolus skewed slot 8 and adjustment barrel inner core skewed slot 16 slide up and down, and band moving vane 5 rotates around its blade front axle 4, thus
The angle making blade 5 changes, and also makes air intake angle change simultaneously.
