Description
Technical field
The present invention relates to non-ferrous metal smelting technology more particularly to a kind of submergences using Bearing score jet mixing flow body
Formula top-blown spray gun.
Background technique
In the prior art, be used for there are mainly two types of immersed top-blown furnace spray guns: the first is shrouded lance, telescopic spray
Rifle is the immersed top-blown spray gun developed on the basis of matching sieve spray gun, and this spray gun is made of multilayer sleeve, each layer of set
There is a kind of fluid in cylinder, multiple fluid is mixed by sleeve.The shortcoming of this spray gun is that spray gun outer layer is easy scaling loss
Deformation, small to fluid flow cooling outside spray gun, intensity of cooling is poor, in addition, spray gun structure is complicated, manufacture difficulty is big.
Second is immersion tube bank mixing top-blown spray gun, and this spray gun is changed on the basis of shrouded lance
Into multitubular bundles are mainly arranged in improvements at fluid mixing, and mixed fluid is shunted by tube bank.This spray
The shortcoming of rifle is that tube bank mixing section welding manufacture is difficult, and mixed fluid cannot be mixed uniformly；Due to empty at mixing section
Between it is narrow, if fluid is got thinner, the pipeline of the inside is very more, and gap is very small between pipeline and pipeline, can not carry out
Welding causes tube bank to fall off in use, and safety accident occurs；Secondly, the depth in spray gun insertion molten bath can not be monitored, make
It is reduced at production efficiency；In addition, being not provided with spray gun cushioning support-saddle, spray gun directly impacts high-temperature fusant in use, makes
It is bent at spray gun, service life of lance is short, and maintenance cost is high.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, provide a kind of structure it is simple, it is easy to use, safe can
It leans on, mixed flow effect is good, the uniform Bearing score injection immersed top-blown spray gun of mixed flow.
For achieving the above object, the technical solution adopted by the present invention are as follows: a kind of Bearing score injection immersed top-blown spray gun,
Including hollow gun body, gun body is cylindrical shape, and one end of gun body is closed end, and the other end is open end, which is characterized in that described
The inner cavity of gun body is divided into mixing section, conveying section, eddy flow section and turbulent section from closed end to open end, and a cartridge is from closing
End central coaxial is arranged with a connecting pipe outside the intracorporal cartridge of rifle to penetrating in gun body and extending in turbulent section, seals
Side pressure sampler is installed, side pressure sampler insertion gun body is interior and connects connecting pipe outside the gun body of closed end；The gun body side of mixing section
At least two fluid interfaces are provided on wall；At least one Lavalle injection apparatus, Lavalle injection dress are installed in the gun body
Setting between two fluid interfaces of arbitrary neighborhood；Cyclone is installed in the gun body of the eddy flow section.
Further, the cyclone is vane type cyclone.
Further, the Lavalle injection apparatus includes plectane, and the center weld of plectane is on connecting pipe, outside plectane
Disc and the inner wall of gun body are seamlessly connected, and offer several Lavalle holes on plectane.
Further, the plectane with a thickness of 2mm~200mm, quantity >=2 in the Lavalle hole on same plectane.
Further, cushioning support-saddle is installed on the gun body outer wall of the conveying section, buffer is installed in cushioning support-saddle.
Further, the buffer is spring buffer or rubber bumper.
Further, length >=100mm of the conveying section；The length of turbulent section is 100~1000mm.
The invention has the benefit that
(1) structure is simple, easily manufactured, material saves, safe and reliable.
(2) fluid mixing is more uniform, after the Lavalle hole injection that stream passes through Bearing score injection apparatus, in the form of horn-like
It is mixed into following fluid, to keep various fluid mixing more uniform；The deep-controlled of spray gun insertion molten bath is realized, is improved
The production efficiency that immersed top-blown furnace is smelted.
(3) cushioning support-saddle effectively overcomes spray gun bring during stirring molten bath and impacts to spray gun, and spray gun is not allowed
Flexible, spray gun service life extends, and improves work production rate, reduces production cost, effectively eliminates to the vertical of melt
Impact, melt splash is less, reduces blocking of the high-temperature fusant crust block to waste heat boiler.
(4) the full cornerite cyclone of vane type is used, eddy flow effect is more preferable.
