Abstract
The utility model discloses a blast furnace iron notch hinged top dust-arrester, comprising a tuyere platform (1), a dust arresting hood (2), a dust arresting pipeline (3) and a hanging winch gearing (4). The dust arresting hood (2) is a slanted top surface, and is connected with the upper hanging winch gearing (4); the dust arresting hood (2) is hinged on the outboard edge of the tuyere platform (1) and above an iron notch; the hood body can swing up and down around the hinged point; the outlet of the hood is corresponding to the dust arresting pipeline (3); the hood body is on the top of the iron notch, and can not influence the using of the spray gun and the iron notch drill. While in normal work, most of the dust just bleeding from the iron notch directly enters into the dust arresting hood (2), and is immediately aspirated away by the top outlet. The slanted top surface of the dust arresting hood (2) ensures to be adapted with the airflow direction of the dust, and simultaneously can furthest facilitate the passing and the polling of the personnel.
Description
Technical field
The utility model relates to a kind of novel dust removing device at blast furnace iron notch collection flue dust, especially can make things convenient for the hinged top of tuyere platform operation to absorb the dirt device.
Background technology
At present, during the blast furnace iron notch flue dust collecting, adopt two kinds of ways usually: 1. adopt side-suction type, this method is to arrange the air suction inlet under the tuyere platform of iron notch both sides, and volume is little, does not influence the operation on the tuyere platform, but because the air suction inlet is arranged in the Tie Kou both sides, not on the route that flue dust emits outside naturally, can only lean on place, air suction inlet negative pressure to inhale, realize flue dust collecting, when flue dust is big, the negative pressure at place, air suction inlet can not unrestrictedly increase, and must have bigger flue dust to loose outward, and dust removing effects is not good.2. adopt cross sliding type top, casting house tap drain top to absorb dust hood, this top is absorbed dust hood and is arranged on the outer naturally route that emits of flue dust, but owing to hindering reasons such as tuyere platform operation, far away apart from iron notch, flue dust has been dispersed herein, it is bulky that Gu Hengyishiding absorbs dust hood, add that the cross moving track span is big, the support volume is big, causes the total system volume big, weight is big, is difficult for arranging.
Summary of the invention
In order to overcome the shortcoming of existing two kinds of blast furnace iron notch method for dust removals, the utility model provides that a kind of volume is little, in light weight, good dedusting effect, also makes things convenient for the blast furnace iron notch hinged top of tuyere platform operation to absorb the dirt device.
The technical scheme that its technical problem that solves the utility model adopts is: the dirt device is absorbed on blast furnace iron notch hinged top, comprise tuyere platform, dust excluding hood, cleaning shaft, hang winding plant, dust excluding hood is a sloped top face, and be connected with the winding plant of hanging of top, can utilize and hang winding plant and hang fixing and lifting and swinging.
Above-mentioned dust excluding hood is hinged on outer ledge, the iron notch top of tuyere platform, and cover body can swing up and down around pin joint, has outlet to aim at cleaning shaft on the cover, and cover body does not influence the use of clay gun, iron perforater just at the top of iron mouth.
During works better, because this dust excluding hood is on the outer naturally route that emits of flue dust, the flue dust overwhelming majority of just emerging from iron notch directly enters dust excluding hood, is siphoned away from top exit immediately.The sloped top face of dust excluding hood had both guaranteed to adapt to the air flow line of flue dust, simultaneously also can abdicate the expensive real estate of tuyere platform herein to greatest extent, be convenient to personnel by with patrol and examine.Air port above the iron mouth needs maintenance, when changing, utilizes the winding plant of hanging of top, and dust excluding hood is put down certain distance, and the sloped top face of dust excluding hood has just become the platform of a spaciousness, has made things convenient for operation.
The beneficial effects of the utility model are, have comprised that side-suction type and cross sliding type top absorbs the advantage of dirt device, volume is little, in light weight, efficiency of dust collection is high, simple in structure, make things convenient for the tuyere platform operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a working state figure of the present utility model;
Fig. 2 is inspecting state figure of the present utility model.
1. tuyere platforms among the figure, 2. dust excluding hood, 3. cleaning shaft is 4. hung winding plant.
Embodiment
The dirt device is absorbed on blast furnace iron notch hinged shown in Figure 1 top, comprise tuyere platform 1, dust excluding hood 2, cleaning shaft 3, hang winding plant 4, dust excluding hood 2 is a sloped top face, and is connected with the winding plant 4 of hanging of top, can utilize to hang winding plant 4 and hang fixing and lifting and swinging.Dust excluding hood 2 is hinged on outer ledge, the iron notch top of tuyere platform 1, and cover body can swing up and down around pin joint, has outlet to aim at cleaning shaft 3 on the cover, and cover body does not influence the use of clay gun, iron perforater just at the top of iron mouth.
During works better, because this dust excluding hood 2 is on the outer naturally route that emits of flue dust, the flue dust overwhelming majority of just emerging from iron notch directly enters dust excluding hood 2, is siphoned away from top exit immediately.The sloped top face of dust excluding hood 2 had both guaranteed to adapt to the air flow line of flue dust, simultaneously also can abdicate the expensive real estate of tuyere platform 1 herein to greatest extent, be convenient to personnel by with patrol and examine.
Fig. 2 absorbs the inspecting state of dirt device for blast furnace iron notch hinged top, air port above the iron mouth needs maintenance, when changing, that utilizes the top hangs winding plant 4, and dust excluding hood 2 is put down certain distance, the sloped top face of dust excluding hood 2 has just become the platform of a spaciousness, has made things convenient for operation.
Claims (2)
1, a kind of blast furnace iron notch hinged top absorption dirt device comprises tuyere platform (1), dust excluding hood (2), cleaning shaft (3), and it is characterized in that: this dust excluding hood (2) is sloped top face, and dust excluding hood (2) is connected with the winding plant (4) of hanging of top.
2, blast furnace iron notch hinged top absorption dirt device according to claim 1, it is characterized in that: this dust excluding hood (2) is hinged on outer ledge, the iron notch top of tuyere platform (1), and cover body can swing up and down around pin joint.
