Fig. 1 is overall structure diagram of the invention.Fig. 2 is the structural representation of the sectional view of one embodiment of the present of invention
Figure.The present invention proposes that a kind of anti-material of centrifugal spray dryer glues wall device, including hothouse 4, hot air duct 2, hot air pipe
Road 2 is used to import the hot-air of dried material, and hothouse 4 includes outer wall 1, inner wall 3, and outer wall 1 is set to the outermost of hothouse 4
Portion, inner wall 3 are the hollow body of double wall composition, and hot air duct 2 is set to the middle part of outer wall 1 and is circumferentially symmetrically distributed in left and right
Both ends offer the hot wind deflector hole 5 of several arrays, the air inlet end of hot wind deflector hole 5 and going out for hot air duct 2 on inner wall 3
Air port end is connected, and material removing device is additionally provided on inner wall 3.
As a kind of preferred embodiment, the air opening end of hot air duct 2 is equipped with deflector apron 6.
As a kind of preferred embodiment, the deflector apron 6 of the left and right sides is in parallel direction, and the deflector apron 6 on right side is used
In guiding hot wind into Fig. 2 cavity first half, left side deflector apron 6 guides hot wind into latter half, to prevent hot wind two-way
Into somewhere formation disorder air-flow.
As a kind of preferred embodiment, material removing device includes permanent magnet 7, electromagnet, and permanent magnet 7 is set to inner wall
At 3 inner surface, electromagnet is set to the outer surface of inner wall 3, and permanent magnet 7 and electromagnet are cooperatively connected；Due to of the invention
Effect cannot avoid completely to reduce material wall sticking phenomenon, therefore outer wall 1 is removed when the present invention is out of service, connect electromagnetism
The power supply of iron, Mobile electromagnetic iron simultaneously drive the movement of permanent magnet 7 to strike off viscous wall material.
As a kind of preferred embodiment, hot wind deflector hole 5 is axially evenly distributed on inner wall 2 along the axis of hothouse 4,
Hot wind deflector hole 5 extends to internal layer from the outer layer of inner wall 3, for hot wind direction to be converted to the tangent line of the inner wall 3 along hothouse 4
Direction.
As a kind of preferred embodiment, the air inlet of hot wind deflector hole 5 is pyramidal structure, facilitates increase intake.
As a kind of preferred embodiment, the wall surface of hot wind deflector hole 5 is plane, to facilitate carry out cleaning work.
As a kind of preferred embodiment, hot wind deflector hole 5 includes circumferential symmetrical one 5-1 of deflector hole, deflector hole
Two 5-2, three 5-3 of deflector hole, four 5-4 of deflector hole, five 5-5 of deflector hole, six 5-6 of deflector hole, deflector apron 6 draw the hot wind of pressurization
To first half of the invention, hot wind quickly flows in the cavity of hothouse 4, enters along a tangential direction through hot wind deflector hole 5
In 4 cavity of hothouse, air-flow is divided into the air-flow that multiply is quickly flowed along cavity tangential direction by six circumferentially distributed deflector holes 5
