The dust-break mechanism includes the U-shaped steel pipe being connected horizontally below dust collection cover, and the opening of the U-shaped steel pipe is far from factory
Setting, the both ends of the U-shaped steel pipe offer pressure-air import inside room, and the pressure-air import is connected with high pressure drum
Wind turbine；
The side of the U-shaped steel pipe far from dust collection cover offers outlet air gap；
The one side wall that the U-shaped steel pipe is located at outlet air gap is equipped with tablet deflector, and another side wall is led equipped with bending
Flowing plate, the bending deflector include the oriented inclined rake of tablet deflector, and be connected to below rake and with it is flat
The parallel vertical component effect of plate deflector.
Technique effect：Dust collection cover is arranged around fire door, then the dust for collecting fire door discharge is arranged through dust discharge pipeline
Go out, U-shaped steel pipe is arranged below dust discharge cover, and when high pressure blower works, the pressure-air in U-shaped steel pipe can be stitched via outlet air
Gap is discharged, and to form a U-shaped high pressure air curtain below dust collection cover, the dust that fire door comes out is blocked in U-shaped high pressure air curtain
It is interior, and the opening of U-shaped steel pipe can largely reduce outer discharge of the flue dust into workshop, have far from being arranged inside workshop
Effect ensures harm of the operating personnel from high-temperature smoke, reduces flue dust and leaks, improves workshop atmospheric environment, in addition, the present invention is set
The tablet deflector set reduces the width of the air outlet in outlet air gap with bending deflector, and pressure-air is entered by outlet air gap
To between tablet deflector and bending deflector, then it is discharged via smaller air outlet, can enhances to form U-shaped high pressure air curtain
Current rate, prevent dust from leaking to significantly more efficient.
The technical solution that the present invention further limits is：
Further, the U-shaped steel pipe is located at side of the bending deflector far from tablet deflector equipped with the first reinforcing rib
Plate.
A kind of preceding aluminium melting and holding furnace fire door air curtain dust collection cover, it is separate that the U-shaped steel pipe is located at tablet deflector
The side of bending deflector is equipped with the second stiffener plate.
A kind of preceding aluminium melting and holding furnace fire door air curtain dust collection cover, between the vertical component effect and tablet deflector away from
From for 1-2cm.
The width of a kind of preceding aluminium melting and holding furnace fire door air curtain dust collection cover, the outlet air gap is 4cm.
The beneficial effects of the invention are as follows：
（1）The first stiffener plate and the second stiffener plate that the present invention is arranged, can support tablet deflector to be led with bending
Flowing plate avoids tablet deflector from blowing deformation by pressure-air with bending deflector；
（2）The distance between vertical component effect of the present invention and tablet deflector are 1-2cm, i.e. the discharge U-shaped steel pipe of pressure-air
Air outlet size be 1-2cm wide, not only can largely enhance the current rate to form U-shaped high pressure air curtain, but also can be by U
Pressure-air in shape steel tube is effectively discharged.
