Movable tundish tipping table dust removal device and dust removal method using same

Abstract

The invention provides a movable type tundish tipping table dust removal device and a dust removal method using the same. The device includes: a fixed frame, which is divided into at least two openings at the upper end along the smoke and dust area, and side openings on the same side. The sub-smoke and dust area; the fixed pipeline is connected with the induced draft fan; the track is arranged on the fixed frame; the L-shaped car body includes a horizontal beam and a vertical beam, the horizontal beam is movable, and is arranged on the track, and the vertical beam is used for To install the movable door, and the movable door driving mechanism used to drive the movable door to move; the lifting cover is arranged above the L-shaped vehicle body, the lifting cover has a structure that fits with the upper opening of the sub-smoke and dust area, and is connected with the fixed A mobile ventilation duct connected by pipelines; a lifting drive mechanism, connected between the lifting cover and the L-shaped vehicle body, drives the lifting cover to move up and down. The smoke and dust of the present invention can be sucked to the dust collector for unified and centralized treatment without spilling into the working space.

Description

technical field [0001] The invention relates to the technical field of steelmaking auxiliary equipment, in particular to a movable tundish tipping table dust removal device and a dust removal method using the same. Background technique [0002] There is a molten steel isolation layer made of refractory materials in the middle of continuous casting. After the continuous casting tundish is used, there are residual molten steel and steel slag inside. When it is tipped over, a large amount of dust and radiant heat will be generated. The dust containing refractory materials is harmful to human health. Working in this environment for a long time will cause diseases such as pneumoconiosis and lung cancer. [0003] In the prior art, the movable tundish tipping table dedusting device consists of the following parts: a fixed frame device, a movable cover device, a fixed pipeline device, and a track. The main function is: when the tundish tilting table is working, all the smoke and du...

Problems solved by technology

[0005] There is a certain gap between the air outlet pipe of the mobile hood device and the fixed pipe interface, mainly to ensure that there is no friction and collision between the two during the moving process, but the existence of the gap will cause smoke and dust to leak out; the distance between the mobile hood device and the fixed frame A certain gap is also left between the mobile cover device to facilitate the movement of the mobile cover device. There is a certain gap between the mobile door and the ground to prevent negative pressure and allow a part of cold air to enter through the gap. However, the existence of the gap has caused The leakage of smoke and dust affects the working environment of the entire workshop
