Protective sliding door used for steel slag treatment

Abstract

The invention discloses a protective sliding door used for steel slag treatment, comprising a track, and a moving and travelling device which is matched with the track, wherein the moving and travelling device is hung on the track, and a door beam provided with a flexible door is fixed on the moving and travelling device. When high-temperature steel slag splashes in a workshop, splashed slag firstly collides with a hinged flap, the impact of the splashed slag can be relieved as the hung hinged flap is flexible so as not to cause secondary splashing, and simultaneously the hinged flap has resistance to high-temperature splashed slag, thus being not easy to damage; after air flow such as smoke dust, steam and the like passes through a chain layer, the air flow is blocked by a rubber door layer and can not overflow from the workshop, so as to realize environmental protection; as the hinged flap and the rubber door are fixed in a hanging way, and both have certain flexibility, when the instant impact of the air flow is caused by rushing, slashing, explosion and the like, the flexible hinged flap and the rubber door can effectively relieve and absorb the impact kinetic energy of the air flow, and also can be automatically uncovered by the air flow when the impact pressure is over-high, thus realizing fast explosive venting, and avoiding the damage to the closed workshop.

Description

technical field [0001] The invention relates to a protective sliding door, in particular to a protective sliding door for steel slag treatment, which is mainly used in the steel slag treatment workshop to protect the slag splash and airflow impact generated during the steel slag crushing and water quenching process, and to prevent Harmful smoke and dust overflow the workshop to pollute the environment. Background technique [0002] During the processing of steel slag in iron and steel plants, it is often necessary to carry out operations such as drop hammer crushing, water spray cooling, and water quenching of steel slag. During the operation, a large amount of smoke and dust will be generated; Large amounts of steam shock etc. The above smoke, dust, slag splash, airflow impact, etc. will cause safety hazards to production personnel and pollute the environment. In order to avoid the hazards of smoke, slag splash and airflow impact generated during steel slag treatment, ste...

AI Technical Summary

Problems solved by technology

In actual use, there are the following disadvantages: (1) Steel slag splashes produced by steel slag smashing and crushing and water quenching explosion are mostly high-temperature particles, and the temperature can reach up to 800°C. The steel plate door cannot alleviate the impact of high-temperature slag splashing, and the door panel is damaged quickly; and Steel slag will be bounced by the door to form a secondary splash, causing a safety hazard

(2) The smoke and airflow generated during steel slag processing will sometimes be discharged in a large amount in an instant, resulting in airflow impact, and the steel plate door cannot relieve the airflow impact, causing damage to the door panel and the workshop
