Description

one

A shaft cooler for cooling granular materials is primarily intended for use in the building materials industry and is used in the manufacture of cement, claydite and similar granulated materials.

A shaft cooler is known for cooling granular materials, for example, expanded clay, containing two annular shafts with perforated concentrically mounted walls, loading and unloading parts connected to air inlet manifolds.

The design of the well-known HiaxTiioro refrigerator is complicated and cumbersome, laborious and unreliable in operation, does not provide high-quality cooling of the granular material.

The aim of the invention is to improve the quality of the material and increase the operational reliability of the refrigerator.

This is achieved by the fact that the walls of the shafts are made of vertical metal rods installed with a gap, and the loading part is additionally equipped with a casing with openings connected to the air inlet manifold.

FIG. 1 shows the proposed refrigerator in two projections; in fig. 2 is a cross section A-A; in fig. 3 - shell with rods, node I.

The shaft cooler consists of two ring shafts 1 with perforated concentric walls 2, loading section 3 with case 4, discharge part 5 consisting of a cone collector 6 and a feeder unloader 7. The ring shafts 1 are enclosed on the outside in a metal case 8.

0 Perforated walls 2 include steel rods 9, which are freely mounted around the perimeter of the annular shafts 1 with a certain gap. The rods 9 are freely missed in the shells 10, which are installed at a distance of each other from the annular shafts 1 at a certain distance from each other and rigidly fastened to each other and with a cone collector 6 by rods 11. The cooled air is supplied through the air inlet manifold 12, and the exhaust air is removed through the air ducts 13. The casing 4 is provided with openings 14 and an air intake manifold 15. The refrigerator operates as follows.

5 The firing material flows from the furnace into the charging part 3, from which, gradually lowering downwards, enters the annular gap between the perforated walls 2. The cooling air is provided to the air diffuser

0, the collector 12 enters the inner annular shaft 1, passes through an annular gap between the perforated walls 2 filled with hot material, and cools it. Exhausted hot air from the casing 8 is discharged through ducts 13. The cooled material from the annular gap between the perforated walls 2 enters the cone collector 6, and from there into the discharger-discharger 7. Rods 9, freely passed through the holes in the shells 10 and installed with some cooling air gap, easily replaced when necessary. The metal loading part 3 is cooled from the outside by flowing air, which is sucked through the opening 14 in the casing 4 and exits on the other side of the casing 4 through the air inlet manifold 15.
