Description

The invention relates to the field of heat treatment of granular materials by burning them in a rotary kiln followed by cooling in a planetary refrigerator and can be used in the building materials industry for the production of cement clinker, lime, expanded clay, in the metallurgical and chemical industries for the production of pellets.

The aim of the invention is to reduce material consumption and increase operational reliability.

In FIG. 1 shows a general view of a planetary refrigerator; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 1; in FIG. 4 is a section bb in FIG. 1.

The planetary refrigerator contains a rotary kiln 1 and installed on

circles in the form of a crown planetary tubes 2 with lifting arms 3, adapter pipes 4 for supplying material and removing heat carrier. The planetary pipes from the unloading ends have air chambers 5 with a cavity 6 located opposite the material rails 7 of the lifting plates 3. The air chambers are connected to the air outside the driving manifold along the axis of the planetary tubes using nozzles 8 (using, for example, a copying device , not shown in Figs. 1-4), Air chambers 5 are rotated along the ends of planetary tubes by means of rollers 9. The lifting bars 3 are perforated and covered outside by the casing 10, and mounted from the discharge end between the casings of the lifting bars Ani sector 11 roundabout

washers. The rotary kiln 1 is equipped with a burner 12.

Planetary refrigerator operates as follows.

The material 7 from the rotary kiln 1 through the transition pipes 4 enters the planetary pipes 2 and during rotation is distributed along the lifting plates 3 in the form of layers moving to the discharge, and is discharged through the openings 13 in the air chamber 5. Cold air flows through the pipes 8 in the cavity 6 of the air chambers 5 and through the holes 14 between the sectors of the ring washer, it enters the cavities formed by the lifting bars 3 and the casings 10, spreads along the entire length of the planetary tubes 2 and flows out through the voids in the perforated lifting bars 3 in. A layer of material for each loaded shelf. The heated fluid through the transition pipes 4 enters the rotary kiln 1 and is consumed to burn fuel entering through the burner 12.

Thanks to the effective cooling of the material on the lifting bars of the planetary cooler during filtration in the air layer, the length of the planetary tubes and, accordingly, their mass are significantly reduced, which reduces the static and mechanical loads of the furnace body, and the operational reliability of the furnace installation as a whole increases.

by stifling chambers allows air to be pumped into each refrigerator, and the combination of this annular cavity with lifting plates with a perforated bottom, externally covered by a casing, provides air to the material layer while it is on the plates. This intensifies the cooling process and contributes to the most rational use of the coolant without leakage past the material layer and significantly reduces the length of the refrigerator, and consequently, its weight (material consumption) is reduced.

Installing sectors of the annular washer between the casings of the perforated lifting shelves creates a tightness between the annular cavity of the distribution head and the discharge end of each planetary pipe. ;
