Complete and Environmental security, optimizes the cover structure that gathers dust and can effectively ensure that harm of the operating personnel from high-temperature smoke, reduces flue dust and leaks,
Improve workshop atmospheric environment.
The content of the invention
The technical problems to be solved by the invention are that the flue dust of high temperature can leak to workshop, influence factory when opening fire door
Room atmospheric environment and personnel safety, the shortcomings that overcoming the prior art, there is provided a kind of aluminium melting and holding furnace fire door air curtain dust collection cover,
In order to solve the above technical problems, the present invention provides a kind of aluminium melting and holding furnace fire door air curtain dust collection cover, including dust collection cover,
Dust discharge pipeline is communicated with above the dust collection cover, lower section is connected with the dust-break mechanism for forming U-shaped high pressure air curtain；
The dust-break mechanism includes being connected horizontally on the U-shaped steel pipe below dust collection cover, and the opening of the U-shaped steel pipe is away from workshop
Portion is set, and the both ends of the U-shaped steel pipe offer pressure-air import, and the pressure-air import is connected with high pressure air blast
Machine；
The side of the U-shaped steel pipe away 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 equipped with bending deflector,
The bending deflector includes the oriented inclined rake of tablet deflector, and be connected to below rake and with tablet water conservancy diversion
The parallel vertical component effect of plate.
Technique effect：Dust collection cover is arranged on around fire door, for collecting the dust of fire door discharge, is then arranged through dust discharge pipeline
Go out, U-shaped steel pipe is arranged on 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, so that in one formed below U-shaped high pressure air curtain of 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 away from being set 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 put 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 discharged via less air outlet, can strengthen to form U-shaped high pressure air curtain
Current rate so that significantly more efficient prevent dust from leaking.
The technical solution that further limits of the present invention is：
Further, the U-shaped steel pipe is located at side of the bending deflector away from tablet deflector and is equipped with the first stiffener plate.
A kind of preceding aluminium melting and holding furnace fire door air curtain dust collection cover, it is remote 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 vertical component effect and the tablet deflector away from
From for 1-2cm.
A kind of preceding aluminium melting and holding furnace fire door air curtain dust collection cover, the width in 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 set, can support tablet deflector and bending deflector,
Tablet deflector is avoided to blow deformation by pressure-air with bending deflector；
（2）The distance between vertical component effect of the present invention and tablet deflector be 1-2cm, i.e. the discharge U-shaped steel pipe of pressure-air goes out
Air port size is 1-2cm wide, not only can largely strengthen the current rate to form U-shaped high pressure air curtain, but also can be by U-shaped steel
Pressure-air in pipe is effectively discharged.
