Abstract
The utility model discloses a dustproof telescopic hood for the gravity dust separator of a blast furnace. The dustproof telescopic hood comprises an electrohydraulic push rod (1), a telescopic cross brace (2), a dustproof soft cloth (3), a middle bearing plate (4), a connecting plate (5), a lower bearing plate (6), a lifting lug (7), a bottom reinforcing ring (8), middle reinforcing rings (9), a top reinforcing ring (10) and a companion flange (11); the lower bearing plate (6) and the lifting lug (7) which are used for supporting the middle reinforcing rings (9) are arranged on the bottom reinforcing ring (8); the connecting plate (5) and the middle bearing plate (4) used for supporting the upper components are arranged on the middle reinforcing rings (9); the top reinforcing ring (10), the middle reinforcing rings (9) and the bottom reinforcing ring (8) are connected through the dustproof soft cloth (3); the upper end of the telescopic cross brace (2) is connected with the electrohydraulic push rod (1); the lower end of the electrohydraulic push rod (1) is connected with the lifting lug (7); and the electrohydraulic push rod (1) and the telescopic cross brace (2) move up and down to drive the lifting lug (7) so as to realize the motion of the telescopic cross brace. The dustproof telescopic hood can be adjusted according to the height of an ash heap, thereby ensuring that a sealed space is formed during the ash discharging process, and no dust is raised.
Description
Technical field
The utility model relates to a kind of dustproof taper telescopic cover, especially can be with the flexible up and down dust cover of the grey height of heap when iron and steel metallurgical industry gravity blast furnace dust catcher dust stratification is drained.
Background technology
The blast furnace that iron and steel metallurgical industry is used to smelt iron can produce a large amount of dusts in the gravitational precipitator in process of production, regularly discharge by ash-valve.Because the gravitational precipitator inside and outside differential pressure is big, and materials flow speed is very fast relatively, very easily forms airborne dust, the way that prevents airborne dust at present is with atomized water dust to be carried out humidification, but still can't control airborne dust fully in discharging process.
Summary of the invention
In order effectively to overcome the drawback that the atomized water air-humidification method can't suppress airborne dust fully, the utility model provides a kind of anti-airborne dust taper telescopic cover, and this device can not only be locked the collection dust, and can be upper and lower flexible along with the grey height change of heap.
The technical scheme that its technical problem that solves the utility model adopts is: it is made up of companion flange, roof reinforcement circle, dustproof soft cloth, middle fixing collar, fishplate bar, middle supporting plate, bottom fixing collar, hanger, bottom plate, Electrohydraulic push rod, flexible bridging.Wherein companion flange links to each other with the roof reinforcement circle, the roof reinforcement circle links to each other with middle fixing collar by dustproof soft cloth, middle fixing collar links to each other with the bottom fixing collar by dustproof soft cloth again, fishplate bar and middle supporting plate are installed on the fixing collar wherein, on the fixing collar of bottom hanger and bottom plate are installed, the hanger of bottom fixing collar links to each other with flexible bridging one end, the other end of flexible bridging links to each other with Electrohydraulic push rod, the Electrohydraulic push rod base links to each other with platform, like this when Electrohydraulic push rod is done retraction movement, the bottom fixing collar that drives dust cover by flexible bridging and hanger moves upward, after the bottom fixing collar is moved upwards up to certain position, bottom plate on the fixing collar of bottom is with regard to the fishplate bar on the fixing collar in the middle of the jack-up, middle fixing collar moves up, after middle fixing collar was moved upwards up to certain position, the middle supporting plate on the middle fixing collar moved up with regard to the fishplate bar of the last middle fixing collar of jack-up, shortens whole telescopic cover so successively.In the process that Electrohydraulic push rod is stretching out, the bottom fixing collar by flexible bridging and hanger band and move downward, the middle fixing collar on the telescopic cover moves down under the gravity effect, and last whole telescopic cover has been launched into a cone-shaped hood.When putting ash, whole telescopic cover stretches uncaps on the railway carriage of dress ash, and telescopic cover always guarantees to put the space that forms a sealing in the grey process along with grey stack height moves up, thereby reaches the purpose of no airborne dust.After having put ash, whole telescopic cover retraction, thus form minimum space.
The beneficial effects of the utility model are: the ash of can guaranteeing to fall in putting grey process forms the space of a sealing, thereby reaches the purpose of no airborne dust, and in not whole telescopic cover withdrawal of time spent, it is little to take up room, compact conformation.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is always schemed for anti-airborne dust telescopic cover;
Accompanying drawing 2 is the telescopic cover kinematic scheme;
Among the figure: (1) is that Electrohydraulic push rod, (2) are companion flange for middle fixing collar, (10) for roof reinforcement circle, (11) for bottom fixing collar, (9) for hanger, (8) for bottom plate, (7) for fishplate bar, (6) for middle supporting plate, (5) for dustproof soft cloth, (4) for flexible bridging, (3).
The specific embodiment
For clearly demonstrating technical characterstic of the present utility model,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
A kind of gravity blast furnace dust catcher described in the utility model is prevented the airborne dust telescopic cover, mainly is made up of Electrohydraulic push rod (1), flexible bridging (2), dustproof soft cloth (3), middle supporting plate (4), fishplate bar (5), bottom plate (6), hanger (7), bottom fixing collar (8), middle fixing collar (9), roof reinforcement circle (10), companion flange (11); The piston rod part of Electrohydraulic push rod (1) links to each other with the upper end of flexible bridging (2), the lower end of flexible bridging (2) links to each other with the hanger (7) of telescopic cover, hanger (7) is connected with bottom fixing collar (8), bottom fixing collar (8) is gone up bottom plate (6) is installed, bottom fixing collar (8) is connected with a plurality of middle fixing collars (9) by dustproof soft cloth (3), middle fixing collar (9) is gone up installation can be by the fishplate bar (5) and the middle supporting plate (4) of bottom plate (6) picking-up, fixing collar (9) is connected with roof reinforcement circle (10) by dustproof soft cloth (3) in the middle of going up most one, and the companion flange (11) of roof reinforcement circle (10) links to each other with the gravitational precipitator ash discharging hole.When the piston rod of Electrohydraulic push rod (1) is done retraction movement, the bottom fixing collar (8) that drives telescopic cover by flexible bridging (2) and hanger (7) moves upward, after bottom fixing collar (8) is moved upwards up to certain position, bottom plate (6) on the bottom fixing collar (8) is with regard to the fishplate bar (5) on the fixing collar (9) in the middle of the jack-up, middle fixing collar (9) moves up thereupon, middle fixing collar (9) above the jack-up successively makes whole telescopic cover progressively shorten so then.In the process that the piston rod of Electrohydraulic push rod (1) is stretching out, be with bottom fixing collar (8) to move downward by flexible bridging (2) and hanger (7), middle fixing collar (9) on the telescopic cover moves down under the gravity effect successively, and last whole telescopic cover launches.
