Abstract
The invention relates to a lifting type top draft hood for trapping smoke dust. The lifting type top draft hood comprises a dedusting flue (13) and a cover body (4) of the dedusting flue (13). The cover body is arranged below a girder (1) and is opposite to a blast-furnace tapping opening. The lifting type top draft hood is characterized in that a gear motor (6) is further arranged on the girder, one end of the gear motor is connected with a brake (7), one end of the brake is connected with a gearbox (8), one side of the gearbox is provided with a power output shaft (9), the power output shaft penetrates through the gearbox, the two ends of the power output shaft are respectively provided with a main rope coiling block (11), and the main rope coiling block is connected with the cover body through a rope in a matched mode. The lifting type top draft hood has the advantages that the structure is simple, operation is convenient, an operator can adjust the height between the cover body and the tapping opening in real time according to the actual production situations to fully trap the smoke dust at the tapping opening, so that the smoke dust trapping effect is improved, and the working environment is improved.
Description
Technical field
The present invention relates to a kind of dedusting, dust collection equipment for metallurgy ironmaking, particularly a kind of liftable top suction hood.
Background technology
The flue dust that the blast furnace iron notch of metallurgical ironmaking is emerged, under the effect of HTHP, is spurting and penetrates and the diffusion of rising rapidly from tapping hole, for normally carrying out of ensureing to produce, conventionally can top suction hood be set above the tapping hole of blast furnace, in order to trap flue dust.Because the top suction hood under prior art is fixed on girder substantially, cannot be according to practical condition and moving lifting trapping flue dust, so top suction hood can only trap part flue dust in the time of blast furnace casting, collection at large to flue dust can be diffused in surrounding environment, brought great harm to environment and operating personnel.
Summary of the invention
The object of the invention is to solve the problem that is fixed on the top suction hood trapping flue dust weak effect on girder of prior art, and a kind of liftable top suction hood is provided.
The object of the invention is to be achieved by the following technical programs:
For trapping a lift top suction hood for flue dust, comprise dust-removing flue and cover body thereof, it is relative with blast furnace iron notch that cover body is located at girder below, it is characterized in that girder is provided with the sleeve pipe being slidably matched with cover body, and sleeve pipe one end and dust-removing flue are connected; On described girder, be also provided with reducing motor, reducing motor one end is connected with brake, brake one end is connected with gear-box, gear-box one side is provided with power output shaft, power output shaft is through gear-box, and in its two ends symmetric position, a main rope drum being set respectively, main rope drum is connected by rope and cover body.
On the basis of technique scheme, the present invention can also have following further technical scheme.
The described sleeve pipe other end is connected with push-pull valve, and push-pull valve one end and sleeve pipe are interconnected, and its other end and dust-removing flue are interconnected, and the keying by push-pull valve is to control the throughput in dust-removing flue.
Described each main rope drum one side is provided with auxiliary rope reel, and auxiliary rope reel is connected by rotating shaft and main rope drum, and auxiliary rope reel is connected by rope and cover body.
Described power output shaft two ends symmetric position arranges respectively a commutator, and each commutator is connected with corresponding main rope drum respectively.
Described cover body shell symmetric position arranges respectively hanger, and hanger is provided with the roller being rotatably assorted with it, and corresponding roller is connected by rope with main rope drum, auxiliary rope reel respectively.
Described cover body below is also provided with spacing frame, and in the time that cover body drops in spacing frame, cover body forms spacing cooperation with spacing frame, the lower position while decline for restriction cover body.
Described internal surface of sleeve pipe symmetric position arranges respectively slide rail, is slidably matched along its axis direction and sleeve pipe at the guide effect lower cover of slide rail.
Beneficial effect of the present invention is: simple in structure, easy to operate, operating personnel can adjust cover body apart from tapping hole height in real time according to practical condition, fully to trap the flue dust of tapping hole, this has not only improved smoke catching effect, has also improved working environment.
Below just accompanying drawings and embodiment the present invention is further described.
