Description
Technical field
It the utility model is related to pipeline dedusting technology field, and in particular to a kind of detachable collecting hood of blast furnace dedusting.
Background technology
In ironmaking processes, although taking cover closure to stokehold casting runner and airborne dust point sets up fixed flue dust collecting
Cover, but actual production operation in, to the resistance to material of casting runner carry out maintenance activity when, it is necessary to overall pulling down and recover installation it is fixed
Flue dust collecting cover, is removed and the set-up time is typically at 35 minutes or so, while is removed and installed repeatedly and flue dust collecting cover is caused
Certain damage and deformation, adds maintenance cost.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of detachable collecting hood of blast furnace dedusting, realizes ironmaking
The quick disassembly and installation of stokehold casting runner airborne dust point flue dust collecting hood.
The utility model is achieved by the following technical solution：
A kind of blast furnace dedusting detachable collecting hood, including collecting hood are provided, connected at described collecting hood upper end outlet
There is inner sleeve, the upper end outer peripheral face of described inner sleeve, which is arranged, is fixed with sealing plate, and outer tube is fixed with described sealing plate,
Dust outlet tube is provided between described outer tube and inner sleeve, described dust outlet tube passes through the connection through both tube chambers with outer tube
Bar is detachably connected, and filled media seals between described dust outlet tube and outer tube.
After collecting hood is fixed on inner sleeve bottom by sealing plate and outer tube consolidation, then by outer tube and dust outlet tube
The connecting rod of setting is realized and is detachably connected, and has shortened dismounting and the set-up time of equipment, using medium-tight dust outlet tube and outside
Sleeve pipe prevents flue gas leakage, simultaneously because during installation and removal, it is only by fixed jacket pipe, dust outlet tube is outer by inserting
It is fixed between sleeve pipe and inner sleeve, reduce the damage and deformation of collecting hood, reduce maintenance cost while improve installation, tear open
Unload efficiency.
Preferably, the both sides of described outer tube are respectively fixed with hanger.
By setting hanger, hung, be easy for installation and removal using crane gear, improve operating efficiency.
Preferably, described medium is soft material.
Soft material is conveniently squeezed between outer tube and dust outlet tube, convenient to realize sealing, and during dismounting, is easily taken out,
Convenient operation.
Installation process of the present utility model：By crane gear hanging at the hanger of outer tube, inner sleeve will be connected
Collecting hood is sling, and dust outlet tube is installed between insertion inner sleeve and outer tube, with connecting rod fixed jacket pipe and going out dirt after regulation
Pipe, gap between dust outlet tube and outer tube after insertion, can be clogged with some soft materials；During dismounting, the soft of filling is first removed
Material, then with crane gear hanging hanger at and somewhat lifted, to insert connecting rod can easy removal fall, last lifting
Equipment, which falls, disengages this collecting hood and dust outlet tube, is hoisted to storeroom.
The beneficial effects of the utility model：
First, the disassembly and installation function of dedusting collecting hood can quickly be realized, practical operation is convenient, efficient；
2nd, low cost, simple in construction, operation simplifies.
Brief description of the drawings
Fig. 1 is scheme of installation of the present utility model；
Shown in figure：
1st, collecting hood, 2, inner sleeve, 3, outer tube, 4, connecting rod, 5, dust outlet tube, 6, medium, 7, hanger, 8, sealing plate.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
A kind of detachable collecting hood of blast furnace dedusting, including collecting hood 1, it is connected with the described upper end outlet of collecting hood 1
