Description

The invention relates to devices 1 for cooling friable granular material in rotary kilns, mainly when calcining carbonaceous materials.

A limestone device for cooling the material, containing a lined drum with burning and cooling zones, has a cooling tube inside the lower section of the drum forming section for primary cooling of the material, which in the transition zone of the cooling zone freely enter the collection collector in the burning zone. However, the availability of the open air secondary blowing air eliminates the possibility of using a cooling device, a nairiger, white n decorative Portland cements, and also calcining carbonaceous materials, as the material from the furnace drops, a repeated oxidation of the reduced clinker elements and an increase in carbon loss occurs. materials.

In order to intensify the process of cooling the material by cooling the corus, in the proposed device, the furnace body is equipped with buckets fixed to it and connected to the tubes, immersed in a container with water.

FIG. 1 shows the proposed device - a longitudinal section; in fig. 2 - section

but A - L in FIG. one; on fng. 3 - a unit for introducing water pipes into a drain header; on fng. 4 - pipe, cross section.

The cooling device includes a corus 1 of the cooling zoo of the rotating nechi; } 1 is 1 irrigating unit 2 for cooling the oven corns from the outside; mounted on the housing, a gripping bucket 3, immersed B filled with water; awn 4 n connected to the water conduit of the plumbing pipes 5 installed along the forming corns of the inside of the day's cooling zone, the outlet ends of which are freely entering into the collector 6 connected to the 4 Water pipes 5 Spabjeps rib g rigidness 7.

The device works in the following way.

Posture:; The outdoor irrigation unit 2 water, washing the outer surface of the corns 1 of the cooling zone, enters the tank 4, from which, with a bucket one and a half buckets 3, rotates the dix with the housing 1. It is fed into the internal cooling pipes 5. Water, removing the material from the material, flows into the collector 6, from where gravity flows into tank 4.

PRIORITY AND MEASUREMENT j) e te

The device for cooling the rotating drum chain containing the placed

inside the body but forming a pipe, combined at the ends by collectors, characterized in that, in order to intensify the process

cooled the furnace body, the body is provided with buckets fixed to it attached to the pipes, immersed in a container with water.
