SU580222A1 - Device for removing spillage of blast furnace skip pit - Google Patents

Description

one

The invention relates to skip lifts and can be used in ferrous and non-ferrous metallurgy.

A device for cleaning waste from a skip weaver of a blast furnace is known, which contains a bucket elevator installed in a skipway, which returns spilled debris to the skip hoist, trays for unloading debris into skip 1.

However, this device is difficult, cumbersome and does not provide effective removal of spillage, requires significant labor costs for maintenance.

The purpose of the invention is the development of a simple, not cumbersome device that ensures the complete removal of spillage from the skip we and the complete mechanization of labor in this area. To do this, in the proposed device on the skip floor, we are hinged sheets. One end of each sheet is connected by a flexible pull to a winch installed outside the skip station. The sheet hinge supports are installed in front of the bucket elevator, which is intended for lifting spillage, feeding it into the chute hopper loading chute.

FIG. 1 shows the proposed device in the plan; in fig. 2 - the same device, cross section; in fig. 3 - it's about 2

longitudinal incision; in fig. 4 shows a platform with a draining pump, top view.

The device contains a skip 1 (see Fig. 2) mounted on rails 2 of the inclined bridge

3 in a skip hopper 4, a chute 5 for feeding coke into a skip and a funnel 6 with a bolt 7 for feeding ore, sinter, rolled into a skip. On the skip floor, we laid two folding sheets 8 (see Fig. 1 and 2), hingedly fortified

in front of folding trays 9, which in turn are hingedly secured in front of a national spill tank 10 (see Fig. 2 and 3). In the latter, a tensioning sprocket 11 of the bucket elevator 12 is installed, equipped with a drive 13 and a driving sprocket 14, under which is installed a pumping chute 15 for feeding debris into the chute chute chutes. Folding sheets and folding trays with flexible rods 16 (see Figs. 2, 3, and 4) are connected to

Winches 17. To prevent debris from falling under the folding sheets and folding trays between them and the walls of the skip we installed sealing devices 18. To remove spills from the skip, and

dust winches 17 by means of flexible tg 16 rises up the unsecured end of the folding sheets 8, expanding them around the hinged end. Store spills and dust on them in folding trays.

9, which also hoist 17 with

using flexible tg 16, turn them around a hinged end and pour the material spilled in them into the container 10. The bucket elevator 12 lifts the spillage from the collecting tank and feeds it into the oscillating chute 15. The latter feeds the spillage into the coke chutes and into the skip.

The proposed device allows us to completely mechanize the removal of spillage from skip we and eliminate the emergency filling of skip we, which allows us to prevent the loss of production and eliminate the labor costs of cleaning the skip we.
