Abstract
Abstract An apparatus for charging a shaft furnace for burning and sintering materials in lump form includes a distribution column and a plurality of distribution flaps which are mounted for pivotal movement adjacent a lower cone edge of the cone and are movable by a link arrangement between different positions to form different truncated columns which are coaxial with the distribution cone and have different diameters. To control the flow and charging of material, each of the distribution flaps preferably have a deflector plate which is secured to the flap and the spaced arrangement adjacent its end.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
In an apparatus for charging a shaft furnace for burning and sintering material in a lump form, which material is selected from a group consisting of limestone, dolomite, magnesite, cement and the like, said apparatus including a distribution cone, a plurality of distribution flaps pivotally mounted adjacent a lower edge of the cone, said flaps having impact surfaces forming a truncated cone which is coaxial to the distribution cone and means for pivoting the flaps between various positions to make it possible to vary the diameter of the base of the truncated cone, said means including a linkage passing axially through the distribution cone, the improvements comprising each of the flaps adjacent an outer end having a deflection plate arranged in spaced relation thereto to form a space therebetween, each of said deflection plates having impact surfaces extending substantially parallel to the impact surfaces of the distribution flap.
Claim 2
Dependent Claim
148 words
In an apparatus for charging a shaft furnace for burning and sintering material in a lump form, which material is selected from a group consisting of limestone, dolomite, magnesite, cement and the like, said apparatus including a distribution cone, a plurality of distribution flaps pivotally mounted adjacent a lower edge of the cone, said flaps having impact surfaces forming a truncated cone which is coaxial to the distribution cone and means for pivoting the flaps between various positions to make it possible to vary the diameter of the base of the truncated cone, said means including a linkage passing axially through the distribution cone, the improvements comprising each of the flaps adjacent an outer end having a deflection plate arranged in spaced relation thereto to form a space therebetween, each of said deflection plates having impact surfaces extending substantially parallel to the impact surfaces of the distribution flap.
Claim 3
Dependent Claim
44 words
In an apparatus according to claim 1, wherein the distance of the space between each deflecting plate and its respective flap decreases as the outer end of each flap is reached so that the surfaces of the flap and plate converge toward each other.
Claim 4
Dependent Claim
25 words
In an apparatus according to claim 2, wherein each deflection plate is secured to its respective distribution flap by means of at least one web.
Claim 5
Dependent Claim
30 words
In an apparatus according to claim 1, which includes at least one web for each distribution flap, said web securing the deflector plate for the flap in the desired position.
