Dust hood device of torch cutting machine for continuous casting

Abstract

The invention discloses a dust hood device of a torch cutting machine for continuous casting. The dust hood device of the torch cutting machine for continuous casting comprises a dust hood body, a dust collection pipe, a pipe support, an electric valve, an air flow guiding device, a driving device and a fixed base. The dust hood body is mounted above a torch cutting machine support through taper pins; the front end of the dust collection pipe is connected with the dust hood body through a bolt; the electric valve is mounted at the tail end of the dust collection pipe and is connected with a main dust collection pipe of a workshop; the air flow guiding device is further arranged in the dust hood body and is connected with a rod end of the driving device through a connecting rod mechanism; and the driving device is arranged on the outside of the dust hood body through the fixed base. During working of the device, the rod end of the driving device extends and drives the connecting rod mechanism to move counterclockwise, flow guiding plates rotate around a rotating center counterclockwise, on the contrary, the rod end of the driving device extends and drives the connecting rod mechanism to move clockwise, the flow guiding plates rotate around the rotating center clockwise, meanwhile, action of the driving device is interlocked with cutting action of the torch cutting machine, and soot of the torch cutting machine can be discharged effectively.

Description

technical field [0001] The invention relates to the continuous casting industry, in particular to a dust removal cover device for a continuous casting torch cutter. Background technique [0002] With the continuous improvement of environmental protection requirements, metallurgical environmental protection requirements also increase. Once the workshop environmental protection does not meet the standards, it must be closed for rectification. Therefore, any equipment that generates a large amount of smoke and dust must use a matching environmental protection dust removal device. In the continuous casting process workshop, there are few equipments that generate smoke and dust, mainly water vapor evaporated at high temperature, which has little impact on the environment. However, after the continuous casting billet comes out, it needs to be flame-cut according to the specified length, and a certain amount of smoke and dust will be generated when the billet is cut. Under the act...

Problems solved by technology

In the continuous casting process workshop, there are few equipments that generate smoke and dust, mainly water vapor evaporated at high temperature, which has little impact on the environment. However, after the continuous casting billet comes out, it needs to be flame-cut according to the specified length, and a certain amount of smoke and dust will be generated when the billet is cut. Under the action of high-temperature and high-pressure airflow, smoke and dust will permeate some workshops, causing local environmental protection to fail to meet standards
