Scope.
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 a kind of viscous wall device of anti-material of centrifugal spray dryer, including hothouse 4, hot air duct 2, warm-air pipe
Road 2 is used to import the hot-air of dried material, and hothouse 4 includes outer wall 1, inwall 3, and outer wall 1 is arranged at the outermost of hothouse 4
Portion, inwall 3 is the hollow body of double wall composition, and hot air duct 2 is arranged at the middle part of outer wall 1 and is circumferentially symmetrically distributed in left and right
Two ends, offer the hot blast pod apertures 5 of some arrays, the air inlet end of hot blast pod apertures 5 and going out for hot air duct 2 on inwall 3
Air port end is connected, and material removing device is additionally provided with inwall 3.
Used as a kind of preferred embodiment, the air opening end of hot air duct 2 is provided with deflector apron 6.
Used 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 hot blast is guided into Fig. 2 cavity first half, left side deflector apron 6 guides hot blast into latter half, to prevent hot blast two-way
Into the disorderly air-flow of somewhere formation.
Used as a kind of preferred embodiment, material removing device includes permanent magnet 7, electromagnet 8, and permanent magnet 7 is arranged at interior
At the inner surface of wall 3, electromagnet 8 is arranged at the outer surface of inwall 3, and permanent magnet 7 is connected with electromagnet 8；Due to this hair
Bright act as reduction material wall sticking phenomenon and can not avoid completely, therefore outer wall 1 is removed when of the invention out of service, connects
The power supply of electromagnet 8, Mobile electromagnetic iron 8 simultaneously drives permanent magnet 7 to move to strike off viscous wall material.
Used as a kind of preferred embodiment, hot blast pod apertures 5 are axially evenly distributed on inwall 2 along the axis of hothouse 4
On, hot blast pod apertures 5 extend to internal layer from the outer layer of inwall 3, for hot blast direction to be converted to along the inwall 3 of hothouse 4
Tangential direction.
Used as a kind of preferred embodiment, the air inlet of hot blast pod apertures 5 is pyramidal structure, convenient increase intake.
Used as a kind of preferred embodiment, the wall of hot blast pod apertures 5 is plane, and cleaning work is carried out to facilitate.
