Slag conglomeration agent is big to pipe wear, it is necessary to wear-resisting；（4）Spray gun perforate charging causes that flue dust is excessive, dust removing effects are poor.
Utility model content
The purpose of this utility model is to provide a kind of Slag Conglomeration Agent Used For Desulphurization of Hot Metal for above-mentioned problem and be automatically added to be
System spray gun, realizes purpose simple in structure, easy to maintenance, reliable.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of Slag Conglomeration Agent Used For Desulphurization of Hot Metal is automatically added to system spray gun, including the lance tube being connected with spray gun rotating device, institute
The lance tube top stated is connected into rifle bend pipe, spray gun bottom of the tube connection nozzle, the lance tube by swivel joint
Middle part is provided with dustproof cover band sleeve bearing, dustproof cover band sleeve bearing connection dustproof cover.
The Slag Conglomeration Agent Used For Desulphurization of Hot Metal is automatically added to system spray gun, and the lance tube is sprayed by upper nozzle lances pipe and lower part
Gun barrel forms, and the upper nozzle lances pipe is connected with the lower part lance tube by thread bush.
The Slag Conglomeration Agent Used For Desulphurization of Hot Metal is automatically added to system spray gun, and the nozzle has at least two outlets.
Beneficial effect：
1. the design of the utility model different angle multiple exit can realize uniform blanking.The angle exported by nozzle two is not
Together, rotary spray gun can be realized in iron bag uniformly by Slag conglomeration agent cloth in the range of two different-diameters.Slag conglomeration agent coverage
Reach 60% molten iron face, avoid reusing the slag removal device cloth increase production time.
2. the lance tube of the utility model is designed using stainless steel segmented conduit, to ensure that pipeline is wear-resisting, the spray gun of design
Using stainless steel thick-walled pipe material, the material and thick-walled structure cause the service life of equipment to reach more than 5 years.
3. the segmental structure of the lance tube of the utility model reduces the shortcomings that long tube machining deformation is big, simultaneously because live
The space of operation is small, and segmentation can mitigate the weight and length of single-piece split-type pipe, easy to manual maintenance and replacement.For being easy to mould
The nozzle 8 of damage and the lower part lance tube 5 of temperature distortion can be replaced with split, reduce the cost replaced every time.
4. the dust-removing cover of the utility model can be in order to removing using Split type structure when burner elements are replaced.It is newly-designed from
Dust-removing cover is adapted to from flumping on support base, the screw thread casing connecting structure that the guide-tube structure and spray gun band of upper lower band cone are oriented to is matched somebody with somebody
Close, can be so that dust-removing cover adapt to the influence of decentraction or deformation in spray gun rotary course automatically, automatically moving ensures to seal always
Good spray gun.

Embodiment
With reference to embodiment, the utility model is furtherd elucidate, it should be understood that following embodiments are only used
In explanation the utility model rather than limitation the scope of the utility model.
As shown in Figure 1, the Slag Conglomeration Agent Used For Desulphurization of Hot Metal of the present embodiment is automatically added to system spray gun, including with spray gun rotating device
The lance tube of 3 connections, the lance tube top are connected into rifle bend pipe 1, spray gun bottom of the tube connection by swivel joint 2
Nozzle 8, lance tube middle part are provided with dustproof cover band sleeve bearing 7, and dustproof cover band sleeve bearing connects dust-proof
Lid 6.
The Slag Conglomeration Agent Used For Desulphurization of Hot Metal is automatically added to system spray gun, and the lance tube is by upper nozzle lances pipe 4 and lower part
Lance tube 5 forms, and the upper nozzle lances pipe is connected with the lower part lance tube by thread bush.
The Slag Conglomeration Agent Used For Desulphurization of Hot Metal is automatically added to system spray gun, and the nozzle has at least two outlets.
The utility model is installed on lift cart by spray gun rotating device bearing and realizes raising and lowering, when spray gun stops
Used time, spray gun is in upper limit, and when starting injection, spray gun is according to designed height, the angle highly according to injection outlet
It is configured with the scope of the cloth of needs.Since spray gun nozzle exit is two, to ensure uniform distribution, injection while spray gun
At the uniform velocity rotated under motor driving by swivel joint.Speed and Field adjustment of the at the uniform velocity rotating speed according to discharging.In order to
Investigate and the hose of U-shaped arrangement is accessed in lifting process, the access bend pipe in spray gun top design, the bend pipe is reduces the resistance of ducting
Abrasion, elbow radius is not less than 10 times of calibers under conditions of pipeline DN40, is taken as R500mm.
To ensure that pipeline is wear-resisting, the spray gun of design uses stainless steel thick-walled pipe material, and the material and thick-walled structure to set
Standby service life reaches more than 5 years.
Since rifle is up to more than 6m, consider to replace space and maintenanceability, by gun body be divided into upper nozzle lances pipe 4, under
8 three sections of portion's lance tube 5, nozzle.The segmental structure reduces the shortcomings that long tube machining deformation is big, simultaneously because the sky of field operation
Between it is small, segmentation can mitigate the weight and length of single-piece split-type pipe, easy to manual maintenance and replacement.Nozzle for being easy to wear
8 and the lower part lance tube 5 of temperature distortion can be replaced with split, reduce the cost replaced every time.
The angle of 8 liang of outlets of nozzle is different, can be realized by rotation and two different-diameters are uniformly distributed in iron bag
In the range of.Realize 60% all standing of molten iron face, avoid reusing the slag removal device cloth increase production time.
Dustproof cover, which is fixed on, skims on platform, by adaptive dedusting sealing cover 6 and dust-removing cover band 7 two parts group of sleeve bearing
Into.Adaptive dedusting sealing cover 7, is bolted in one using subdivision connector, is sleeved on spray gun, by flump certainly except
On dirt lid bearing 7 with well, inside is more than spray gun connector diameter for cylindrical hole diameter, has the guiding conical surface to realize up and down
Upper and lower rifle process automatic guide.
Dust-removing cover band sleeve bearing 7 plays lid supporting role, and welded and installed is on platform, due to skimming platform and lower part is removed
Dust hood designs this needs special set tube dustproof extension and is overflowed from the dust excluding hood tapping of platform lower there are oblique angle.
To ensure with conduit not interfere in spray gun ascending and descending process, and make it that the seal clearance of lid and rifle is minimum, spray gun
The connection mode of epimere and hypomere uses the structure of thread bush, which is positioned using check bolt, and outside sets guide cone
Face structure.When spray gun rotates, gun body exists under eccentric and deformation, and dust-removing cover can automatically move the center change for adapting to rifle
Change.This kind of connector, which designs, make it that the change of split rifle outside diameter is small, and transitions smooth, and steering capability is good, and sealing effect is good.
