Description

one

This invention relates to a technique for drying crushed materials, such as fruit pomace. To dry the crushed materials, drum dryers and mine dryers of the type MC 435, ABM-04, VIS-2 are used.

A device for drying a fountain with low specific weight, e.g. wool, is used, containing a cone-shaped body with an inlet for supplying a mixture of material with heat carrier and an outlet for discharging material, and there are a cone-shaped insert with 3 lower parts of the body annular slits and; 1prplai-1mi visors.

However, the known device does not provide high performance. In addition, when drying crushed materials with high humidity, clumping of the material occurs and it sticks to the inner surface of the housing and to the cone-shaped insert. This causes the dryer to stop to clean it and results in a decrease in productivity.

The purpose of the invention is to intensify the drying process and prevent sticking; -;

For this purpose, in the proposed installation, the lower part for drying of crushed materials is made cylindrical, i.e. neck; i; ocTci; cHHO in a 1.5-foot bottom, in the central part of which there is a spherical-shaped gas distribution grid. A collector is installed in the middle part of the body but of a circumference; it is made in the form of a straight tube of a non-temporal cross section with nozzles; directional coolant supply.

FIG. I depicts the proposed installation, a longitudinal section through the drying chamber; in fig. 2 shows a section along A - A in FIG. one.

The plant for drying crushed materials consists of the lower cylindrical part 1, the junction 1, it gradually into a sesquioral 2, .-. Heating in the central part a spherical gas distribution distributor 3. under which the air duct 4 is installed; and the upper conical part 5, which has a discharge chute 6, a reflector 7 and a diffuser 8 with discharge chambers m 9. In the middle part of the installation housing around the circumference there is a variable section collector 10 with nozzles 1, and in the upper part there is a loading device 12 with an inlet pipe 13. To separate the dried material from the heat-Celp resilient cyclone 14.

cross section along the length of 1; creating the same head over the entire cross section of the chamber through the nozzles. And it comes under pressure. heat carrier. The nozzles 11 are positioned in such a way that they direct the heat carrier in a continuous stream along the wall of the unit casing at a speed that prevents the particles from sticking to the walls. The gradual transition of the cylindrical part 1 of the installation housing to the one and a half bottom 2 contributes to the creation of a turbulence of the jet and intensive mixing of the product. The product falling on the spherical gas distribution grid 3 is thrown into the zone of the vortex flow by the directed flow of air flowing through the air tube 4 and the gas distribution grid 3.

Thus, the material being in the intense vortex flow of the coolant is dried and carried to the upper conical part 5 of the installation housing, where it is discharged through the tray 6 and smaller particles are carried by the air flow into the diffuser 8 and through nozzle 9 are directed into the cyclone 14 where are separated from it. The reflector 7 serves to hold the wet material in the chamber and increase its residence time in hot air for complete dehydration.
