Abstract

The invention can be used in the preparation of refractory quartzite ramming masses. The invention allows for self-regulation of the gas distribution process and the rational use of heat of the drying agent. The gas supply box of the dryer is placed under the perforated plate to accommodate the material M to be dried. In the holes in the slab, racks 5 of the corner bar are installed (L Yu x 9d 00

The invention relates to devices for drying bulk materials, mainly sands, and can be used in various types of impurities in the preparation of refractory materials, for example, quartzite, ramming masses, especially small volumes.

The purpose of the invention is to provide self-regulation of the gas distribution process and the rational use of heat of the drying agent.

FIG. 1 schematically shows a dryer with the described gas distribution device; figure 2 is the same, top view; on fig.Z - section aa on fkg, 2; figure 4 - section bb in fig.Z,

The dryer for bulk materials contains a hopper 1 with a gas supply duct 2 located under a horizontal perforated plate 3 for placing a dried material on it having openings 4. On the plate 3, guides in the holes 4 are made in the form of racks 5 of an angular profile.

Over the stands 5 there are caps made in the form of overturned cups 6 vertically movable, the stands 5 themselves are provided with threaded bushings 7 inside and springs 8 freely mounted on the outside 8. The interturn clearance 9 of springs 8 is provided adjustable by means of nuts 10, screws screwed onto the threads 7. Glasses 6

Together with M, C Gz is lowered with flanges 13. At the same time, gaps 9, free from M, and channels for the exit of hot gases to the outside, overlap. 4 il.

on the side of the bottoms 11, they are provided with centering pins 12, which freely enter the inside of the sleeves 7. On the side of the cleaned ends, the caps have flanges 13 supported on the layer of the material being dried.

The dryer works as follows.

By preparing the installation for operation, all cups 6 are preliminarily removed. In accordance with the intended batch of material, depending on the angle of repose in the dry state, the size and shape of particles, the amount of material passing through the interturn clearances 9 per unit of time, a nut 10 through washer set inter-turn clearances 9 springs 8,

The hopper 1 is filled with a loose, moistened material, such as quartz sand, 4 so that the upper coils 5 of the springs 8 remain on the surface. on the surface of the wet material, block the exit of gas through the inter-turn gap 9 of the upper part of the springs 8; sobenno intensively under the flange 13, wherein the material layer closest to the surface

and exerts the least resistance to the gas flow. With the loss of vlade, the material in the flange 13 zone first acquires the properties of flowability and, subject to the law of repose angle, rushes into the inter-turn gap of the springs 8 and dumps their internal channels into the pallet (not shown). the heat carrier is expended only on the evaporation of moisture, and the overheating of the material is excluded, since the material being dried is spontaneously removed from the drying zone. The material that is removed from the drying zone causes a decrease in its level in the hopper 1, followed by the glasses 6, which are supported on the material by the flanges 13, and the interturn clearances 9, free from the material, and the channels for the exit of hot gases to the outside.
