Abstract

The utility model discloses a novel mobile closed dust collection hood for a ladle-to-ladle position in a steel smelting workshop. The dust collection hood is positioned above a ladle-to-ladle position (the ladle-to-ladle position of iron ladles), and a heavy bridge type crane is singly arranged beside the dust collection hood. The dust collection hood comprises a mobile hood, a mobile hood biplate bracket and a ventilating duct, wherein the mobile hood biplate bracket is fixed to the bottom of the mobile hood; the upper end of the mobile hood is mounted on the ventilating duct and reinforced by a lacing wire; and the ventilating duct is provided with a control valve. The utility model has the following advantages: the mobile closed dust collection hood disclosed by the utility model can effectively trap flue gas and clean the operating environment of a workshop; the mobile part is provided with a closed plate to prevent flue dust from flowing out from the tail part; the mobile hood and the heavy bridge type crane work separately without influencing each other; and the fixed part and the mobile part of the mobile hood can be separated through pulleys, so that the leak tightness is good, the air leak rate is low, and the flue gas can be effectively trapped.

Description

A kind of steelshop closes the airtight dust hood of bag position place's new mobile type
Technical field
The utility model relates to field of environment protection, relates in particular to a kind of steelshop and closes the airtight dust hood of bag position place's new mobile type.
Background technology
The molten iron that iron and steel enterprise's blast furnace is produced adopts hot metal ladle to be transported to steelshop by train traction conventionally, and hot metal ladle is risen and winched in front of converter by steelshop heavy duty crane again, and molten iron is poured into and in converter, carried out oxygen blast smelting.But the molten iron that blast furnace is produced can not can be filled each hot metal ladle at every turn, therefore last hot metal ladle may only fill partial volume.Therefore, need to topple over and merge one and completely wrap hot metal ladle at specific station (close bag position) less than hot metal ladle multiple at steelshop, then pour converter into and carry out oxygen blast smelting.Molten iron can produce a large amount of high-temperature smokes, severe contamination steelshop environment from a hot metal ladle toward another hot metal ladle toppling process.Because hot metal ladle all adopts special heavy bridge-type starting engine in factory building to complete in the time toppling over and expire the lifting of iron clad water, if fixed dust hood is set, flue gas is trapped, can affect the lifting operation of starting engine.Therefore need a kind of new technical scheme to address the above problem.
Utility model content
The utility model provides a kind of steelshop to close the airtight dust hood of bag position place's new mobile type.
The technical solution adopted in the utility model: a kind of steelshop closes bag position place's airtight dust hood of new mobile type and is positioned at and closes top, bag position (the ladle-to-ladle position of hot metal ladle), dust hood side is provided with separately heavy bridge crane, this dust hood comprises mobile cover, mobile cover biplate support and ventilator trunk, mobile cover biplate support is fixed on mobile cover bottom, mobile cover upper end is arranged on ventilator trunk and by lacing wire and reinforces, and by-pass valve control is also installed on ventilator trunk.
Above-mentioned mobile cover biplate support comprises support, and guide rail and limit switch prop up the bottom that is set up in mobile cover biplate support, and described support upper end is provided with guide rail, and two terminations of guide rail are provided with limit switch.
Above-mentioned mobile cover comprises fixed part and moving portion, being shaped as of mobile cover is inverted U-shaped, and bottom is wide, top is narrow, fixed part is positioned at moving portion upper end and departs from by pulley and moving portion, the rear end of moving portion is fixed with closure plate, the centre of the upper end of moving portion is provided with crossbeam, the both sides of moving portion are connected and fixed by the closure plate of rear end and middle crossbeam, the both sides of the bottom of moving portion are separately installed with motion-work wheel and follow-up pulley, are all connected with synchronous machine on motion-work wheel and follow-up pulley.
The beneficial effects of the utility model: Mobile enclosed dust hood of the present utility model can effectively trap flue gas, cleaning shop operating environment; The closure plate that moving portion is provided with can prevent that flue dust is excessive from rear portion; Mobile cover separates work with heavy bridge crane, does not exert an influence mutually; The fixed part of mobile cover and moving portion adopt pulley to depart from, good leak tightness, and air leak rate of air curtain is low, and flue gas is effectively trapped.
