Abstract
A kind of steel-wire galvanizing nitrogen, which is smeared, to be wiped air knife and is related to tool used in hot dip of steel wire zinc technology.Mainly to solve the problem of that existing air knife will cause that air flow method is uneven to be influenced zinc layers surface quality and the thickness uniformity and design.It includes cutter hub, there is axial steel wire channel in cutter hub center, nitrogen inlet is equipped at the top of cutter hub, the first air cavity of annular is equipped in cutter hub, first air cavity is connected by pipeline with nitrogen inlet, the second air cavity of annular is equipped with below first air cavity, the air cavity partition of annular is equipped between first air cavity and the second air cavity, several stomatas are evenly equipped on the air cavity partition of annular, first air cavity and the second air cavity are connected by the stomata on air cavity partition, air knife lip is mounted on the bottom of the second air cavity, air knife lip is connected with steel wire channel, air knife lip is up-small and down-big tubaeform.Advantage is to improve zinc-coated wire zinc layers surface quality and the thickness uniformity.
Description
Technical field:
The utility model relates to tool used in hot dip of steel wire zinc technology, it is specifically related to a kind of nitrogen and smears wipe air knife.
Background technique:
During steel-wire galvanizing, the vertical thick zinc layers of plating generally use nitrogen to smear and wipe, and nitrogen blows to steel wire by air knife
Surface can make steel wire surface zinc layers smooth, while control adjustment zinc layer weight by nitrogen pressure.Smear wipe during, because
The problem of unreasonable structure of existing air knife, it is uneven to will cause air flow method, influences zinc layers surface quality and the thickness uniformity.
Summary of the invention:
The technical problem to be solved by the utility model is to provide one kind can specification air flow direction, uniform air flow speed,
The steel-wire galvanizing nitrogen of raising zinc-coated wire zinc layers surface quality and the thickness uniformity, which is smeared, wipes air knife.
Above-mentioned purpose is achieved in that it includes cutter hub, and there is axial steel wire channel in cutter hub center, is equipped at the top of cutter hub
Nitrogen inlet, interior the first air cavity for being equipped with annular of cutter hub, the first air cavity is connected by pipeline with nitrogen inlet, under the first air cavity
Side is equipped with the second air cavity of annular, and the air cavity partition of annular, annular air cavity partition are equipped between the first air cavity and the second air cavity
On be along the circumferential direction evenly equipped with several stomatas, the first air cavity and the second air cavity are connected by the stomata on air cavity partition, gas
Knife lip is mounted on the bottom of the second air cavity, and air knife lip is connected with steel wire channel, and air knife lip is up-small and down-big tubaeform.
In process of production, nitrogen enters the first air cavity by air inlet, by the stomata on partition, into the second gas
Chamber, uniform air flow speed, has air-flow with laminar condition, and air knife interior air-flow is evenly distributed, and air-flow is equal in steel wire circumferencial direction
Even distribution uniformly smear to zinc-coated wire surface and be wiped, solve since air-flow unevenness causes zinc-coated wire under the guidance of knife lip
Surface quality is poor, zinc coating thickness unevenness problem.
The utility model has the advantages that: this method is by improving air knife internal structure, specification air flow direction, uniform air flow speed
Degree, air-flow are uniformly distributed in steel wire circumferencial direction, and knife lip plays guiding role to air-flow, improve air velocity, improve galvanized steel
Silk zinc layers surface quality and the thickness uniformity.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A view of Fig. 1.
Specific embodiment:
Referring to Figures 1 and 2, it includes cutter hub 1, and there is axial steel wire channel 2 in cutter hub center, be equipped at the top of cutter hub nitrogen into
Mouth 3, interior the first air cavity 4 for being equipped with annular of cutter hub, the first air cavity are connected with nitrogen inlet by pipeline, are set below the first air cavity
There is the second air cavity 5 of annular, the air cavity partition 6 of annular is equipped between the first air cavity and the second air cavity, on annular air cavity partition
Several stomatas 7 are along the circumferential direction evenly equipped with, the first air cavity and the second air cavity are connected by the stomata on air cavity partition, air knife
Lip 8 is mounted on the bottom of the second air cavity, and air knife lip is connected with steel wire channel, and air knife lip is up-small and down-big tubaeform.
