Abstract
The invention discloses a kind of breeze blowing distributors, are made of connecting flange, blowing supervisor, centrum, ceramic tube, blowing branch pipe, white steel washer, end cap and fixing bolt, in the pressure-bearing rapid wear surface build-up welding tungsten carbide of the end cap；The ceramic embedded pipe of branch pipe wall is blown inside the centrum；The ceramics bore is consistent with external branch bore, prevents coal dust from causing to wear to inner wall in transmission process eddy generation.It is 92mm that above-mentioned blowing supervisor, which selects internal diameter, with a thickness of the thick-walled pipe of 8mm.By 28 blowing branch pipes inside above-mentioned centrum.New coal powder blowing distributor of the invention has the characteristics that wear-resistant, can reduce the mill leakage frequency of distributor, to mitigate the labor intensity of employee, reduction spare parts consumption guarantees the steady production of blast furnace.
Description
Technical field
The present invention relates to a kind of pulverized coal distributors, and in particular to a kind of breeze blowing distributor.
Background technique
Currently, coal injection is to replace part of coke in furnace charge in intensification of smelting process in BF production, the one of fuel ratio is reduced
Kind technical way.The breeze blowing distributor used before Baogang BF, due to unreasonable structure, material selection wearability
It does not reach requirement, leads to distributor in use, leakage of pulverized coal failure frequently occurs, not only increases the labor of service personnel
Fatigue resistance, and influence the normal production of blast furnace.
Summary of the invention
The purpose of the present invention is to provide a kind of breeze blowing distributors, make to solve existing breeze blowing distributor
The problem of generation leakage of pulverized coal failure numerous with process intermediate frequency.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of breeze blowing distributor, by connecting flange, blowing supervisor, centrum, ceramic tube, be blown branch pipe, white steel washer,
End cap and fixing bolt composition, in the pressure-bearing rapid wear surface build-up welding tungsten carbide of the end cap；It is blown in branch pipe inside the centrum
The ceramic embedded pipe of wall；The ceramics bore is consistent with external branch bore, prevents coal dust internal in transmission process eddy generation
Wall causes to wear.
It is 92mm that above-mentioned blowing supervisor, which selects internal diameter, with a thickness of the thick-walled pipe of 8mm.
By 28 blowing branch pipes inside above-mentioned centrum.
The present invention has the advantage that
New coal powder blowing distributor of the invention has the characteristics that wear-resistant, and the mill that can reduce distributor leaks the frequency, from
And mitigate the labor intensity of employee, spare parts consumption is reduced, guarantees the steady production of blast furnace.
Detailed description of the invention
Fig. 1 is the present invention a kind of structure chart and A-A cross-sectional view of breeze blowing distributor.
In figure: 1, connecting flange；2, blowing supervisor；3, centrum；4, ceramic tube；5, it is blown branch pipe；6, white steel washer；7, it holds
Lid；8, tungsten carbide overlay cladding；9, fixing bolt.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification to be taken off
The content shown is not intended to limit the invention enforceable qualifications so that those skilled in the art understands and reads, therefore
Do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the present invention
Under the effect of can be generated and the purpose that can reach, it should all still fall in disclosed technology contents and obtain the model that can cover
In enclosing.Meanwhile cited such as "upper", "lower", " left side ", the right side in this specification ", the term of " centre ", be merely convenient to chat
That states is illustrated, rather than to limit the scope of the invention, relativeness is altered or modified, and is changing skill without essence
It is held in art, when being also considered as the enforceable scope of the present invention.
Embodiment
Referring to Fig. 1, a kind of breeze blowing distributor, by connecting flange 1, blowing supervisor 2, centrum 3, ceramic tube 4, blowing branch
Pipe 5, white steel washer 6, end cap 7 and fixing bolt 9 form, it is characterised in that: are carbonized in the pressure-bearing rapid wear surface build-up welding of the end cap
Tungsten 8；The ceramic embedded pipe 4 of 5 inner wall of branch pipe is blown inside the centrum 3；4 internal diameter of ceramic tube and external branch bore one
It causes, prevents coal dust from causing to wear to inner wall in transmission process eddy generation.
It is 92mm that above-mentioned blowing supervisor 2, which selects internal diameter, with a thickness of the thick-walled pipe of 8mm.
By 28 blowing branch pipes inside above-mentioned centrum 3.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
