Movable type tundish tipping table dedusting device and dedusting method adopting same

Abstract

The invention provides a movable type tundish tipping table dedusting device and a dedusting method adopting the same. The movable type tundish tipping table dedusting device comprises a fixed frame,a fixed pipeline, a rail, an L shaped vehicle body, a lifting cover and a lifting driving mechanism, wherein the fixed frame is divided along a smoke dust area into at least two sub smoke dust areas,openings are formed in the upper ends of the two sub smoke dust areas, and lateral openings are formed in the same side of the lateral direction of the two sub smoke dust areas; the fixed pipeline communicates with an induced draft fan; the rail is arranged on the fixed frame; the L shaped vehicle body comprises a horizontal beam and a vertical beam; the horizontal beam can move and is arranged onthe rail; the vertical beam is used for mounting a movable door and is also used for a movable door driving mechanism for driving the movable door to move; the lifting cover is arranged above the L shaped vehicle body and is provided with a structure fitting the upper end openings of the sub smoke dust areas and a movable ventilating pipeline communicating with the fixed pipeline; and the liftingdriving mechanism is connected between the lifting cover and the L shaped vehicle body and drives the lifting cover to move up and down. According to the movable type tundish tipping table dedustingdevice, smoke dust can be sucked to a dust remover for unified and centralized treatment without being dispersed into a 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] The continuous casting contains a molten steel isolation layer made of refractory materials. After the continuous casting tundish is used, there are residual molten steel and steel slag, which will generate a lot of dust and radiant heat when it is tipped. The dust containing refractory materials is harmful to human health. Extremely large, working in this environment for a long time can cause diseases such as pneumoconiosis and lung cancer. [0003] In the prior art, the movable dust removal device for the tundish tilting table is composed 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, the generated smoke and dust a...

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
