Abstract
A kind of zinc-plated air knife, includes air admission hole（5）, rectangular inlet chamber（1）, rounded hybrid chamber（2）, upper knife lip（3）And lower knife lip（4）；Described air admission hole（5）It is arranged on the right-hand member of air knife；Described inlet chamber（1）It is arranged on the right side inside air knife, it is characterised in that：Described hybrid chamber（2）The centre inside air knife is arranged on, lower right side is provided with towards inlet chamber（1）Hole, left upper portion is provided with towards upper knife lip（3）And lower knife lip（4）Between accelerated passage hole.The utility model passes through in inlet chamber（1）Hybrid chamber is set afterwards（2）So that pressure in air knife is consistent, while by upper knife lip（3）And lower knife lip（4）It is arranged to the electric boiling plate of chromium plating, it is to avoid sticking for cadmia, the plate face that effectively improves galvanized sheet is clean and tidy.
Description
Technical field
The utility model is related to the zinc layers control device in continuous galvanizing line, especially a kind of zinc-plated air knife.
Background technology
Unnecessary zinc liquid is generally struck off in current continuous galvanizing line using air knife, zinc coating thickness is controlled, but it is traditional
Air knife has following defect：1st, the cadmia splashed is often attached on knife lip, is blocked the passage of air-out, is caused on galvanized sheet
Form a white line；2nd, the gas pressure intensity that air knife sprays is uneven, causes the zinc layers of two edge of galvanized sheet uneven.
The content of the invention
Not enough for more than, the purpose of this utility model is to provide a kind of zinc-plated air knife, is that one is set after inlet chamber
Individual hybrid chamber so that gas pressure intensity becomes uniform in air knife, while upper lower knife lip is changed into electric boiling plate and evanohm is plated, it is to avoid
Cadmia sticks, so that the plate face for lifting galvanized sheet is clean and tidy.
The technical solution of the utility model is achieved in the following ways：A kind of zinc-plated air knife, includes air admission hole, is in
The inlet chamber of rectangle, rounded hybrid chamber and upper lower knife lip；Described air admission hole is arranged on the right-hand member of air knife, has 9, etc.
That divides is distributed on the axis of air knife right flank；Described inlet chamber is arranged on the right side inside air knife, by air admission hole with
Air inlet pipe is connected；Described hybrid chamber is arranged on the centre inside air knife, and lower right side is provided with the hole towards inlet chamber, left side
Portion is provided with towards the hole of the accelerated passage between upper lower knife lip；Described upper lower knife lip is arranged on the left end of air knife, upper lower knife lip
Between surround accelerated passage.
The utility model after inlet chamber by setting hybrid chamber so that the air pressure in air knife is averaged, while the knife by above and below
Lip is arranged to the electric boiling plate of chromium plating, it is to avoid cadmia sticks so that the plate face tidiness of galvanized sheet is effectively improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is position view of the air admission hole on air knife.
1 is inlet chamber in figure, and 2 be hybrid chamber, and 3 be upper knife lip, and 4 be lower knife lip, and 5 be air admission hole.
Embodiment
Known by Fig. 1 and Fig. 2, a kind of zinc-plated air knife, include air admission hole 5, rectangular inlet chamber 1, rounded mixing
Chamber 2, upper knife lip 3 and lower knife lip 4；Described air admission hole 5 is arranged on the right-hand member of air knife；Described inlet chamber 1 is arranged in air knife
The right side in portion, is connected by air admission hole 5 with external pipe；Described hybrid chamber 2 is arranged on the centre inside air knife；Described is upper
Knife lip 3 and lower knife lip 4 are arranged on the left end of air knife.
Described air admission hole 5 has 9, and decile is distributed on the axis of air knife right flank, and 9 of decile distribution enter
Stomata 5 causes the gas pressure intensity entered in air knife evenly.
The described lower right side of hybrid chamber 2 is provided with towards the hole of inlet chamber 1, and left upper portion is provided with towards upper knife lip 3 with
The hole of accelerated passage between knife lip 4, can be sufficiently mixed the compressed air of the introduction of inlet chamber 1 so that each section of gas inside air knife
Body pressure is averaged.
Accelerated passage obliquely is surrounded between described upper knife lip 3 and lower knife lip 4, the compressed air blown out obliquely has
Effect improve gas scrape zinc liquid energy power；Described upper knife lip 3 and lower knife lip 4 is the electric boiling plate of chromium plating, is effectively kept away
Sticking for cadmia is exempted from.
During work, then air compressor compressed air is introduced into the inlet chamber 1 of air knife by pipeline from 9 air admission holes 5
It is interior, carry out after preliminary mixing in from the hole of the lower right side of hybrid chamber 2 into hybrid chamber 2, filled in hybrid chamber 2 in inlet chamber 1
The accelerated passage for dividing mixing to pass through again between upper knife lip 3 and lower knife lip 4 obliquely after causing gas pressure average is blown out.
