Abstract
The utility model relates to a dust removal cover, in particular to a dust removal cover for blast furnace top, comprising a cover body and an exhaust pipe; the cover body is arranged on a furnace top receiving hopper by a flange, the cover body is a hollow shell, a skip car inlet and outlet passage opening is arranged at one side of the cover body, an extract opening which penetrates through a cover body wall is arranged at the other side of the cover body, and the extract opening is connected with an exhaust pipe; the dust removal cover is characterized in that: the skip car inlet and outlet passage opening is connected with a sealing door curtain which is a soft rubber frame with a square hole in the middle, and cutting strip shape is formed at the periphery of the square hole of the sealing door curtain, and the door curtain is connected on the cover body at the periphery of the skip car inlet and outlet passage opening. In the utility model, a frame-type sealing curtain structure is arranged at the skip car inlet and outlet passage opening for carrying out soft sealing, the raised dust can be prevented from being spilled over when the skip car unloads on the premise of not affecting the normal operation of the skip car; the dust removal cover has simple structure and high dust extraction efficiency and is safe and reliable.
Description
Technical field
The utility model relates to a kind of dust excluding hood, the very useful dust excluding hood of particularly a kind of State of Blast Furnace.
Background technology
On the blast furnace furnace roof hopper of employing double skip material loading a dust excluding hood is housed, the dust of kicking up when a suction opening is arranged on the dust excluding hood the truck discharging is taken away, because dust excluding hood one side is a truck passage up and down, this side of conventional design is opened wide, the furnace roof dust is kicked up when causing the truck discharging, contaminate environment.Basic reason is that this side is difficult to sealing, and She Ji air quantity can't satisfy dust removing effects routinely, and is very uneconomical again if employing air quantity at double improves dust removing effects, strengthened the operation cost of enterprise.This problem is stranded the blast furnace furnace roof dust removing effects of scratching the double skip material loading for a long time, does not solve so far.
Summary of the invention
At the problems referred to above, the utility model provides a kind of dust removing effects State of Blast Furnace good, with low cost very useful dust excluding hood.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: the very useful dust excluding hood of a kind of State of Blast Furnace, include cover body, induced exhaust, cover body is installed on the furnace roof hopper by flange, cover body is the housing of inner hollow, cover body one side is provided with truck access way mouth, and the opposite side of cover body is offered the bleeding point that runs through a cover body wall thickness, and bleeding point is connected with induced exhaust; It is characterized in that: truck access way mouth is connected with the sealing door curtain, and described sealing door curtain is the middle soft rubber frame that has square hole, and the square hole periphery is the cutting strip, and door curtain is connected on the truck access way mouth cover body all around.
The cover body of described truck access way mouth periphery is provided with fixed frame, the fixed frame circumferentially-spaced is welded with double-screw bolt, have open holes with the double-screw bolt opposite position on the described sealing door curtain, will seal door curtain by open holes and be enclosed within on the double-screw bolt, pressing plate is set and coupling nut on double-screw bolt on the sealing door curtain.
Described cover body is provided with the access door of visual cover body inside.
The structure formation that the utility model adopts truck access way mouth that frame sealing door curtain is set is carried out soft seal, under the prerequisite that does not influence the normal operation of truck, can when the truck discharging, stop the flour dust overflow of kicking up again, the utility model is simple in structure, safe and reliable, the efficiency of dust collection height.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the A of Fig. 1 is to view;
Description of symbols among the figure: the 1-induced exhaust, the 2-truck, the 3-access door, the 4-cover body, 5-truck access way mouth, the 6-fixed frame, 7-seals door curtain, 8-pressing plate.
Embodiment
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1,2:
Press the very useful dust excluding hood of State of Blast Furnace that the utility model is implemented, include cover body 4, induced exhaust 1, cover body 4 is installed on the stove furnace roof hopper by flange, cover body 4 is the housing of inner hollow, because what adopt is double skip 2 material-uploading styles, so cover body 4 one sides are provided with two truck access way mouths 5, the opposite side of cover body 4 offers the bleeding point that runs through a cover body wall thickness, bleeding point is connected with induced exhaust 1, the end of induced exhaust 1 is provided with vacuum fan, form the space of a negative pressure after the vacuum fan work in furnace roof hopper zone, dusty gas is sent to dust-removal system through taking out the dirt airduct. the utility model is under the prerequisite that does not increase air quantity, improve dust removing effects by sealing means, increasing very little situation in investment and be issued to the dust removing effects optimizing. concrete scheme is: be connected with sealing door curtain 7 on the cover body 4 of truck access way mouth 5 peripheries, the frame type soft rubber pad that described sealing door curtain 7 is middle opening square hole, the size of square hole is according to the shape setting of truck 2, to satisfy the seal request of truck 2 when the different positions, sealing door curtain 7 square hole peripheries are the cutting strip, and sealing door curtain 7 is connected on the cover body of truck access way mouth periphery.
Change behind the soft rubber pad senile abrasion for the ease of sealing door curtain 7, be connected with fixed frame 6 on the cover body 4 of truck access way mouth periphery, fixed frame 6 circumferentially-spaced are welded with double-screw bolt, have open holes with the double-screw bolt opposite position on the described sealing door curtain 7, by open holes door curtain is enclosed within on the double-screw bolt, on door curtain, pushes down then and tighten at the double-screw bolt coupling nut with metal platen 8.Cover body 4 is provided with access door 3, and access door 3 is a steel construction, and the inside of visual cover body 4 by its may observe discharging situation and dust removal process, also is to enter the passage that overhauls in the furnace roof hopper simultaneously.
Discussed above only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
