The invention relates to a drying technique, more specifically to a drying bed dryer, and beats the beat used in the chemical industry and other industries of the national economy.

Invention is an increase in productivity.

FIG. 1 roll is offered dryer; in fig. 2 - the same, at the moment of coupling of the retaining roller with one blade, cross section; in fig. 3 - then, at the moment of conjugation of the rotor holding the two blades.

The dryer contains a vertical cylindrical chamber 1, a lid with (L1 3 dm from here a spent drying agent, I-inlet box 4 with naipvbKOM 5, gas distribution 1C1Y1 and reheader 6, discharge device 7 and loading device (not shown), sector (sector compartment) 8 load, shaft 9 with radial blades 10 mounted on hinges 1 1 and connected by means of melcht, with elastic elements 12. On the inside surface of chamber 1 at the border of sections (sector sections) 8 and 1i, respectively with iai manual and unloading devices, mouth A retaining roller is inserted, while the gas-distributing sector lattice 6 in the area of the discharge device 7 has a notch 15.

The dryer works as follows.

Wet material through the loading device (not pumped) enters the vertical cylindrical chamber 1 on sector 8, communicated with the loading device, and as the shaft rotates H, the radial blades 10 move towards the discharge device 7. Under the action of the drying agent supplied through the nozzle 5, gas supply the duct 4 and through the grate 6, the material to be dried is in a fluidized state. In one revolution of the shaft 9 with radial vanes 10, the material is dried and discharged through the device 7. The spent drying agent is discharged from the dryer through the nozzle 3 of the lid. dryers

Wet material is continuously fed to sector 8 (a thin line of

an approximate loading point is indicated) and is in a fluidized state. When the shaft 9 is rotated counterclockwise, one of the radial blades located on the sector boundary engages with the roller 14 and is held until the shaft 9 rotates around its axis at an angle equal to the angle of the sector formed by the blades 10 i.e. until the next blade fits the held blade and overloads the discharge device 7. At the moment of the discharge device 7 closes, the held blade comes out of engagement with roller 14 and returns to its place under the action of elastic elements 12. Similarly, all blades 10 pivotally mounted on the firing 9 are operated. Thus, at any time, any of the radial blades separates sector 8 from the discharge device 7, and for reliable separation and eliminating the possibility of material passage near the wall of the cylindrical vertical chamber 1, the length of the roller 14 is equal to the height of the radial chasper 10.

Claims (1)

Invention Formula A fluidized bed dryer containing a vertical cylindrical chamber with a loading device at the top and with a discharge at the bottom, a gas distribution grid with a sector cut in the area of the discharge device and a shaft located above it along its axis with radial blades dividing the working volume of the cylindrical chamber into sector ones compartments, characterized in that, in order to increase productivity, on the inner surface of the chamber at the border of the sector compartments, communicated respectively with the loading and unloading devices In addition, a holding roller is additionally installed, the height of which is equal to the height of the radial blade, while each blade is hinged on the shaft and provided with elastic elements connecting it with adjacent blades. 70 4h five 7 -U Phie, 3 eight
