Abstract

DOOR FURNACE RECOVERY FUNNEL, divided into compartments and containing a Fixed Case, a small cone funnel suspended from a rod along its axis, with TEMJ, in order to improve the averaging of the mixture before loading into the furnace, it is provided with a cylindrical tube with a lined neck, extended from the receiving side of the charge, located coaxially to the rod.

Description

The invention relates to ferrous metallurgy, in particular, to devices for charging a blast furnace.

The closest to the invention to the technical essence and the achieved result is the receiving funnel of the charging device of the blast furnace, divided into compartments and containing a fixed body, a container with a cone housed in it suspended on,: itango along its axis.

However, the design of the funnel does not allow evenly averaging, to mix different types of materials just before being loaded into the furnace:

The purpose of the invention is to create a cbstructure of a receiving funnel, which allows the coke to be mixed with the ore part of the charge before being unloaded onto the lower cone.

This goal is achieved by the fact that the fixed body and outer funnel are axially provided with a cylindrical tube with a one-sidedly widened neck located inside the funnel coaxially with the cone rod and separating the volume of the funnel into axial and peripheral annular parts.

It is advisable to thread the neck above the pipe with a protective layer of wear-resistant materials and the pipe and its mountains. {Il. One half should be done with the connector perpendicular to the "cool axis".

The drawing shows the receiving Odron in the section along the axis, as applied to the standard double cone filling apparatus.

The receiving funnel contains a stationary outer housing 1, a container 2 with a cylindrical discharge opening, which is closed from the bottom with a cone 3 suspended on a rod. Inside the housing 1, a neck 4 is installed, one-sidedly displaced the center to the left or the right, so that the charge of one of the skips is directed into the cylindrical tube 5, the mouth of the tube is performed 71 -it -1 - with a gap and has a transverse connector. It also has a longitudinal connector for ease of installation and repair. The cylindrical tube 5 is inserted inside the outer funnel - tank 2 coaxially so that it forms two axial volumes around the rod 6 of the hinge ring. fpy6a centering and stability can be supported on the outer funnel with stabilizers 7. The stabilizers are attached to the 5-pipe and can be freely supported on it, - -; . The neck 4, the pipe 5 with the drivers 7, if necessary, as an embodiment, is located on. Jonus 3 and the gateway, together with them on a stationary scale, like that. Provided with a standard charge distributor. In this case, the eagle flange 4 Hte flange is associated with the non-exposed body 1, i.e., it is attached to it. The receiving funnel pa6oT "lef follows the DJHM way, - Loading of the charge could be ocyiftecT 1 le" a yak transporter, Tak th Skip. When skip loading, the charge from the left skip, for example, coke, is poured into the left peripheral clean and is distributed over the LG sol f-l -tm-SJv-swKJvi-tfj: - over the cone When the right skip approaches the iron containing part of the mixture, are loaded through the throat 4 into the pipe 5, and from the bottom they are held down by the central part of the cone 3. After ratruzka dit skips of one of Tnyh nfyuyy1r, ore or sinter is in the axial volume of the funnel, and coke. in the peripheral. Then the cone 3 is lowered and the agglomerate, the flow around the rod 6, is also carried along with it, at the same time the coke from the ring part, the flow around the pipe 5 around the ring, is showered together with the agglome I aToM. . Thus, in the event of a crash in the fall of the drop, the components of the mixture are mixed together to form a mechanical, relatively homogeneous mixture of agglomerate with coke, ..., the mixture is placed on a large cone (in the drawing it is not yet ethane). . After unloading the charge from the receiving funnel, the small cone 3 in the typical distribution together with the outer funnel, the pipe 5 and the neck 4 is rotated 90 times elliptical (not shown) with one-sided widening of the neck 4 or 180 (for the Asymmetric widening of the neck 4jj or 180) changing the location of the ridges of the axial and ring volumes of the charge. Thus, the presence of an asymmetrical hole inside the receiving funnel, which directs the charge into the pipe with a cheap location, allows you to: e types of materials with a multicomponent charge; reduce the segmentation of materials j S1 the influence of the ridges during skip loading, on the uneven distribution of the charge around the circumference in a standard biconical filling device with a rotating distributor.,
