(54) DEVICE FOR CONTINUOUS THERMAL AND CHEMICAL TREATMENT OF BULK MATERIALS

(57) The invention relates to a device for the continuous thermal and chemical treatment of bulk materials. The purpose of the invention is to increase the reliability of the device by ensuring complete removal of the processed material from the discs by contacting the scrapers with the discs. In case K 1 of the device, disks (D) 5, 6, 7 are fixed on the vertical shaft 8, above which are slats 10 with scrapers (C) 11 fixed to them. The ends of the slats 10 enter vertical slots 12 in the side walls; К 1 Due to this, C 11 is in contact with the surfaces D 5, 6 and 7 under its own weight, i.e. image minimum clearance. The bulk material moves alternately from the periphery to the center D and back due to the rotation D 5, 6 and 7, while the material goes from D to D through the holes 9 and the gap between K 1 and D. The grooves 12 keep the strips 10 from turning together with the shaft 8. The minimum clearance between C 11 and D 5, 6, and 7 provides a more complete removal of bulk processed material from the device. 1 hp f-ly, 2 ill.

The invention relates to a technique associated with cooling, heating with a cue or calcining bulk materials in construction, chemical industry, mechanical engineering, food industry and other areas of national economy, and can also be used for conducting chemical heterogeneous reactions,

The purpose of the invention is to increase the reliability of the device by completely removing the material being processed by ensuring the contact of the scrapers with the disks.

FIG. 1 schematically shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

A device for continuous thermal and chemical treatment of bulk materials comprises a housing 1c with connecting pipes 2, 3 and 4 for introducing materials for withdrawal and for blowing (gas supply), respectively.

The inner space in the housing 1 of the device is divided into three sections. The sections are arranged one above the other by movable disks 5, 6 and 7, secured on the vertical shaft 8 with a drive (not shown), and communicated with each other through the holes 9. The disks 5, 6 and 7 alternate with the bars 10, on the bottom which are fixed scrapers 11, made in the form of spirals, for example, Archimedes. The ends of the slats 10 are installed in vertical grooves 12, made in the side walls of the housing 1, with the possibility of vertical movement. Thus, the scraper-helix 11 under its own weight contacts the surface of the disks 5, 6 and 7.

The device works as follows.

The material is fed through the nozzle 2 and it hits the rotating disk 5, where under the influence of the scraper-helix 11 and the rotation of the disk 5 the material moves in both the radial and circumferential directions until it moves to the hole 9. Through the hole 9, the material to be processed falls on a subdisk 6, where under the influence of a scraper-helix 11 moves to the periphery of the disc. BH cut annular gap between the side surface of the disk 6 and the housing t material falls on the movable disk 7

s

and also, as in the upper section, moves to the center, passes the apertures 9 and goes through the nozzle out of the device. The number of sections and related parts can be reduced or increased depending on the desired mode of material processing.

If necessary, through the nozzle 4 BHjTTpb of the housing 1, the required gas is supplied during processing.

Due to the possibility of moving the strips 10 with scrapers-spirals 11 in the vertical direction in the grooves of the walls of the housing 1, the scrapes-spirals 11 are at constant contact with the surfaces of the rotating disks 5, 6 and 7 with a minimum clearance caused by the flat surfaces of the bottom surfaces of the scrapers - helixes and disks 5, 6 and 7, while the size of the gap is not affected by factors such as mounting errors during assembly

which provides the most complete removal of material from the surfaces of rotating disks as it moves along them.
