The invention relates to a drying technique, in particular for drying loose and fibrous materials, and can be used in the textile, chemical, food and other industrial sectors.

A dryer is known for high-strength m theories, for example, having a body and a rotor placed therein with radially spiral rows of vanes made hollow and connected to horizontal ring collectors, the upper of which is connected to a narrowing nozzle for entering a heat transfer fluid, and working the blade surface has perforations for supplying heat transfer fluid to the material being dried tl J

However, this dryer is characterized by an insufficient intensity of the drying process due to the impossibility of

make material mixing in a vertical plane.

Closest to the invention is a dryer for bulk materials, containing a vertical cylindrical housing and nojfijycHo swiveling profiled blades located on the central rod located in it, the rod being enclosed in a sectioned 2 pipe

However, this dryer is also characterized by an insufficient intensity of the drying process.

The aim of the invention is to intensify the drying process by changing the direction of rotation of the material in the horizontal and vertical planes.

This goal is achieved by the fact that in a dryer for bulk materials containing a vertical cylindrical body and rotatable profiled blades located on the central rod, irresistible in it, the rod is enclosed in a pipe sectioned in rus, radial sleeves are additionally fixed on each section of the pipe, the possibility of rotation around their axes installed specified blades, equipped with perforations, and the rod with all elements fixed on it is made in the form of a drive rotor.

FIG. 1 shows a dryer, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

Dryer for bulk materials. It contains a vertical cylindrical body 1 and a hollow rotor 2 exchanged inside it, connected to the shaft 3 of the engine 4. The rotor 2 is located inside the pipe 5, divided into sections 6, kinematically connected to each other and on each of which are mixing devices installed by Rusy on sleeves 7 and made in the form of a cruciate-arranged rotary perforated blades 8, having the possibility of simultaneous rotation both around the rotor 2 and around the sleeves 7. The engine 4 is connected by means of a chain gear 9 with a hollow mouth rum 2, on the outer surface of which, at a height of each torsion, are mounted bevel gears 10, which serve to drive the bevel gears 11 into rotation, which are fixed to the hubs 7 of the blades 8, and the engine 4 is connected to the tube 5 through a system of gears 12, consisting of section 6, for each floor there is a section; the ends of each section are equipped with bevel gears 13. The sections are interconnected by a parasitic gear 14, which is engaged with gear 13 to change the speed 15.

Dryer for bulk materials works as follows.

The drained material is transported by heating medium from a heat generator (not shown) along the rotor 2 from the bottom upwards of the housing 1. Simultaneously with the supply of material, the engine 4 is turned on, which through the shaft 3 with the help of a chain transmission 9 begins to rotate the rotor 2, transmitting, in turn, the movement fixed to at the level of each tusk conic gear 10 and, conical gear 11, which engages with them, on the COTO1ILX the sleeves of 7 blades 8 are fixed, at the same time, in a row of located rus, the blades 8 rotate towards each other. At the same time, the engine 4 rotates the pipe 5, consisting of sections 6, through its gear gear system 12, section 6 for each tier, and section 5 of pipe 5 in a row of tresses located at the expense of bevel gears 13 and engaging gears each other, rotate in the opposite direction. The drained material is captured by profiled blades 8 and draws it into rotation relative to the rotor 2. When leaving the upper tusk to the lower due to the blades 8 to different sides, intensive aerodynamic impact and mixing of the counter-swirling flows of the material mixture and the heating medium occur at the boundary between the rus, which increases the time the material stays in the dryer case 1. Changing the speed of rotation of the variator 15 regulates the drying process by changing the speed of rotation of the blades 8 and, accordingly, the residence time of the material in

zone of each rus. The blades 8 are shaped to prevent the dried material from being pressed to the periphery of the dryer body 1 due to the centrifugal effect of the rotating blades 8, and the blades 8 are also made perforated, which contributes to the intensification of the material drying process due to heat supply from the inside of the blades 8 through perforation, and also removal of moisture through this surface.

The proposed dryer will allow to intensify the process of drying various materials.
