Description

I

Invention Concerning the agglomeration of iron ore in ferrous metallurgy.

Known bowl cooler containing drive lattice ring hopper and a knife-resetter located above

cooling base.

However, in the known construction, the combination of the movement of a material with its filtration by a cooling agent results in a high dust content of the exhaust gas.

The purpose of the invention is to create a design of a cooler cooler, which provides reduced dust content of the outgoing i-ase.

E1o is achieved due to the fact that the cup cooler is equipped with fixed screens above the ejector knife on the outer sides of the bunker in the direction of its rotation} equal to 0, O5-O, 15 cooler circumferences.

FIG. Figures 1 and 2 show the proposed chiller cooler, general view and section.

The cooler has a drive lattice ring hopper 1, having an outer 2 and inner lattice walls 3, a receiving shaft 4, a reset knife 5, an extension 2

I laid over the base of the cooler 6 and fixed screens 7.

Cup cooler works as follows. The hot lumpy material enters the driving grating ring bunker 1, lowers it from top to bottom, and is removed from the base of the pan coolant l 6 with a fixed ejection knife 5 and passes through a layer of hot lumpy material and is removed through the internal lattice wall 3 of the silo.

In the drive lattice ring bunker, the lumpy material is lowered only above the installation site of the knife-dumper. The collapse of the material begins at the time of combining this cross section with the installation site of the knife ejector and ends approximately at a length equal to 0.05-0.15 of the length of the cooler's circumference. In the remaining areas of the aggregate, the material spoi is in a stationary state. In this case, the entire layer of lumpy material is filtered by the cooling agent in the horizontal direction, and both the fixed bed and the moving sing section are filtered.

The bulk of the dust and particles of the material by the flow of the cooling agent was taken out of the bed from the moving bed, the removal from the fixed bed is insignificant. To eliminate this drawback, it turned out to be beneficial to eliminate the filtration of the moving layer by installing fixed IQ screens of length O, O5-O, 15 cooler circumferences. Fixed screens are placed above the knife-ejector from the BHeLUHiix side of the lattice bushser in the direction of its rotation., 15

The application of the invention ensures a stable gathering of lumpy material in the absence of a filter cake through it a cooling agent, eliminates the removal of dust

and separate granules from a layer, and, therefore, a possibility of blockage of walls of the trellised ring bunker. All this provides a high degree of cooling of hot lumpy materials to stabilizes the aerodynamic parameters of the system.

Subject invention

Cup cooler containing a soldered bottom ring hopper and a knife spreader located above; The chiller is characterized by the fact that, in order to reduce the dust content of the exhaust gas, it is equipped with non-movable, 0, O5O, 15 screen lengths of the cooler from the outer sides of the bunker in the direction of its rotation.
