Description

I

This invention relates to the field of ferrous metallurgy, in particular, to devices for the sintering of ores; and other materials with the method of agglomeration.

A known installation for cutting materials, made in the form of an irivod lattice drum with a gas suction and gas duct and a tubing, seals, ZOCHOK loading and discharge units, an equalizer, gas burners, an agglomerate crusher and a segitite-type lamer, which is not in a grid, but also a gas burner, an agglomerate crusher, and a light-weight sealerite device for a non-lattice-type burner, an agglomerate crusher, and a segpeite-type loosener, which is not covered by a gas burner, an agglomerate crusher, and a segitite treadmill, which is attached to the lattice, an air grinder, an agglomerate crusher and a segitite-type lid, do not place on the surface of the grid, but also a gas burner, an agglomerate crusher, and an array of sintering and unloading units;

The disadvantage of such an installation is the need for high-purity treatment of the outer surface of the lattice drum in order to achieve a satisfactory sealing of its joining points with drag-on seals.

In order to reduce the number of harmful iroses and increase production, the drum of the proposed installation is enclosed in a casing, EE 1 Filled as connected to one another with large grounds, iriche the cavity between the cone and the drum is divided by partitions with blowing and detached but displaced but vertical, and blown and vacuum nozzles, rigidly connected with fixed

about

j) wavelengths: both by elements and through compacted hiiiijc - with rotating casing halves.

The described installation is made in the form of an extended drum equipped with gas-blowing devices; and auxiliary lips) for loading the charge and dispensing an agglomerate with a target 10 iroosa - air rocket when the combustion zone moves towards the two layers of the charge at its one-time ignition and the beginning of the process.

Ma FIG. 1 depicts the preferred installation; FIG. 2 - the same view in Ylan; ia flash 3 shows a section Io A- / 4 in FIG. ; in fig. 4 - cxeN.ia load the drum charge in moA; L-HT its ignition.

The proposed installation contains a horizontally mounted drum /, for making icoTOporo heat resistant ns1 resistant material is used.

Inside the drum / rings are located 2, having compensators for eliminating temperature papes. The drum / has slots 3 in all) to the body in the section between baidazhamn, in which it is fixed. The gap area is used as a living section of the grid.

On the outside, a rene-1 reel of the drum / covers 4, states of two and a halves, having Hi. HX x broken cones. The space between the components of the casing 4 and the fire6; i iOM / is divided by partitions 5, which are made in a manner that: the air, which is formed by the formed chambers 6 to the drum grille, is facing in the direction of the DWC, there are curvilinear elements 7, 8, 9, 10, between which are located natchzhp 11, 12, Ii, 14 gas suction and gas-pressure tracts. Curvilinear elements are interconnected between themselves by means of a joint, but they are: relatively relatively new to the casing 4 and the partitions 5, but therefore between the elements; 7, 8, 9, 10, with pipes with 11, 12, 13, 14 n a casing with non-city walls 5 are provided for H1lotnn (n | PZhnni or hydraulic), which reduce the amount of harmful P: ODeosop, air leaks, as well as its neretrek n.z one ; 011 i-aiMeiii, 6 to another, Gas pipelines 11, 12, / i, 4 are connected with m of M; aggregate, gas pipelines) tract B is assigned to primary chambers, gas exhaust tract C - two vacuum chambers. Rotation of the drum / transmitted according to the following kinematic yen.ochka: electric motor - connecting coupler - reduction gear small gear - small gearbox (gearbox) - drum /. li nolostn b ;; rabia / are BCHOMoraTe, iBHijH resistors 15-28, the load of which is over the floor, using beams 29, 01 nfa1io11ee outside on / on supports 30-32. The conveyor / 5, non-uniform ;; in the southern part of the route, through the descent boot-visor 16, is installed on the top surface of the armor / dl protection and it is protected from rapid irgsran. The unloading trolley 17, located 1a on the conveyor 18, is working, and, like n conveyor 15, in the shuttle mode, loads the material between the bed layer and the leveling pad 19, 1 of the heat-resistant material. It is provided for the artificial ergregy of the charge material during its laying with a reflector captone 20. fixed on the separating chute / 6 with such a system (). So that the largest ninxri should roll towards the trowel 19. The reflective visor 20 is wide enough for the discharge piece of the discharge trolley 17. In addition, the provision of vibrators and a visor 20 is envisaged. At the joints of the trowel 19 and the knees, seals are observed; So obr :: i); not TOvTbKO smoothes the surface of the bed of the bed, but it also eliminates the possibility of radial movement of air through it to the airway B. Along the drum 1 for ignition; an incendiary device 21 is installed. For removing agglomerate at a length of 6apa6ania 1, the rotor 22 is agro-blasting, the shaft of which is supported by bearings 23 and crushing plate 24.
