Description

Dust collector in continuous casting machine tundish area

Technical Field

The utility model belongs to the technical field of continuous casting, and relates to a dust removal device for a tundish area of a continuous casting machine.

Background

In the casting of steel in continuous casting machines, a large amount of covering agent needs to be put into the tundish for technical reasons. However, a great amount of smoke dust is generated in the process of putting the covering agent, and the smoke dust causes great field environmental pollution and causes damage to the health of production operators. In order to improve the environment, dust removal is required on site.

The existing common dedusting method for the tundish area of the continuous casting machine comprises the following steps:

the first method is to set fixed hood below the workshop roof over the middle tank area, and the hood is connected to the dust eliminating pipeline and the dust eliminating facility to ventilate and eliminate dust. Under the normal condition, the casting cross-workshop height of the continuous casting machine is higher, the distance from the middle tank to the roof above is longer, and the distance is about 25m, so that a huge open space is arranged below the cover, negative pressure cannot be formed by air suction, and the dust removal effect is poor. However, this method has the advantage of simple structure and does not affect the operation of the area, and therefore has application.

The second method is to arrange a movable covering vehicle above the middle tank area, the covering vehicle is supported on a suspended track, the low point of the covering vehicle is higher than equipment in the area, the high point of the covering vehicle is lower than a workshop crane, the covering vehicle is aligned with a main pipeline of a dust removal system in a working position, but a reasonable distance is kept, normal movement of the covering vehicle is not affected, and when the area needs to be subjected to lifting operation, the covering vehicle is transversely moved away. The method has the advantages that the open space below the cover is greatly reduced, the air suction effect is improved, the structure is complex, the weight of the cover car is heavy, under special conditions, the track of the cover car is difficult to set, the cover car is required to be designed into a full suspension mode, namely, the track is only arranged on one side close to the column row of the workshop, meanwhile, the cover car has a certain influence on the operation in the area, the suspension of the cover car is still higher, and the maintenance of moving parts of the cover car is difficult.
