Description

Spiral arm device of collecting cover for dust removal of rolling mill frame

Technical Field

The utility model relates to a dust collecting equipment of rolling mill frame, in particular to portable rolling mill frame removes dust with spiral arm device of entrapment cover.

Background

The dust-removing collecting cover is arranged on the rolling mill frame, is an important measure for effectively treating air pollution caused by water vapor and smoke dust generated in the rolling process of the hot rolled plate, particularly treating a large amount of water vapor-containing smoke dust dissipated outwards from the top of the rolling mill frame, helping the dust-removing system to exert the maximum efficiency, cleanly and thoroughly removing the water vapor-containing smoke dust diffused upwards from the rolling mill frame, and strictly controlling the unorganized emission above the rolling mill frame.

When the steel plate is rolled in the hot rolling initial rolling process, the steel plate needs to be repeatedly rolled back and forth under a frame (commonly known as four-roller reversible rolling), a large amount of cooling water needs to be sprayed in the rolling process, the red steel plate is stimulated by cooling of the cooling water, water mist and dust gas rushing to the sky can be generated instantly, the water mist and dust gas flying to the sky is changed into a mushroom cloud state immediately and is diffused outwards, and the air quality of the whole steel rolling workshop is greatly influenced. The phenomenon is greatly related to the uniqueness of a hot-rolling initial rolling process and a rolling frame, and on one hand, a large amount of cooling water needs to be sprayed in the rolling process to generate a large amount of water mist and dust gas; on the other hand, in the rolling process, the steel plate is rolled back and forth in one rack, so that a dust removal collecting cover cannot be installed on the rack, particularly, the dust removal collecting cover cannot be installed on a medium plate rolling line because the transverse width exceeds eight meters, and once the roller and the steel plate are not well matched, a shell is clamped between four rollers, so that obstacles cannot be removed in time. In order to remove faults as soon as possible, an overhead traveling crane is required to arrive at the site in time for hoisting, and a dust removal collecting fan cover cannot be mounted at the top of the hot rolling frame according to the operation requirement, so that the top of the hot rolling frame is open at present, water mist and dust gas at the top of the rolling mill is diffused, and the problem to be solved urgently in the field of dust removal of the hot rolling primary rolling mill at present is solved. The severe environment not only brings great hidden trouble to safety production, but also seriously affects the ecological environment and the air quality of a production workshop and also harms the physical and mental health of workers.

At present, a frame of a hot-rolling blooming mill (particularly a medium plate rolling line) is not provided with a collecting cover for a dust removal system, the collecting cover for dust removal cannot be installed due to the transverse width of more than eight meters, and a collecting cover supporting frame cannot be installed for supporting and installing the collecting cover due to the fact that motors for driving rollers are densely distributed in the front and the back of the frame without a sufficient place, so that a large amount of water mist and dust generated in the blooming and rolling process are reserved with a window for disorganized dispersion, and the air quality and the ecological environment are influenced.

In view of this, researchers in the field of dust removal have made an effort to develop a dust collecting cover for dust removal of a rolling mill stand and a swing arm device thereof to solve the problem of the unorganized dissipation of the top of the hot-rolling blooming mill stand.
