Description

one

The invention relates to a drying technique and can be used in the chemical, microbiological, and other industries of the industry for drying high-moisture conglomeration and XC materials, for example chlorinated rubber, enzyme preparations.

A known installation for drying high-moisture materials, a housing comprising a material inlet and outlet, and a shredder inside the housing in the form of fixed and movable fingers entering one another, the latter of which are mounted on a disc type 1 rotor.

This installation works as follows. Wet material is fed into the body, where, with the help of the shredder, they destroy the conglomerates formed during drying due to the impact effect of the fixed and moving fingers entering one another.

This setup is closest to the invention in its technical essence and the achieved result.

The disadvantages of the known installation are the Irregularity of the material processing and the difficulty of creating conditions for drying thermosensitive materials with a wide range of particle sizes.

The purpose of the invention is to intensify heat and mass transfer and improve the quality of drying.

For this, the rotor is made many brown and on the upper surface of the disk of each tusa central and peripheral blades are fixed, and to the body walls parallel to

individual gas distributing manifolds for each tier are attached to the discs, distribution rings from the bottom, and the latter are communicated with the corresponding manifold through the holes made in the casing walls located between the fingers.

In addition, a singing device with a rotary valve-free gas distribution grid, made up of trapezoid elements, and a gas duct under it, in which flow dividers equipped with electromagnetic coils are located, is connected to the material input nozzle.

FIG. 1 is a schematic representation of the installation, the longitudinal section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 — node II in FIG. one; in fig. 5 is a section along BB in FIG. four; in fig. 6 is a section along BB in FIG. four.

The installation contains a feeder I, pneumoguns 2 with adjustable angle of inclination, gas flow dividers 3, trapezoid elements 4, constituting a gas distributor grating without threshold, threshold 5, trunnions 6, electromagnetic coils 7 placed in housing 8, chopper 9 in the form of disks 10 fixed on shaft and nesush, their fingers 11 and central 12 pnerferpnye 13 blades, gas distributing manifolds 14 with holes 15, distribution rings 16 and fixed fingers 17. The installation works as follows. The source material to be dried is continuously fed by the feeder 1 to the pneumodal belt 2, which is simultaneously transporting, since the gas flow of the coolant is evenly distributed along the length of the gas chamber by the dividers 3 and is directed by the trapezoidal elements 4 towards the threshold 5. By changing the angle of the pelvic pulmonary 2 its performance is regulated. In pneumosilver 2, moisture is removed from the material that is substantially free and foreign inclusions are separated due to their deposition under the force of gravity or the magnetic field on the metallic inclusions in case of electromagnetic coils 7. The separable particles are removed from the lattice of the pulverizer 2 by turning it about pivots 6 with disconnection of electromagnetic coils 7. Magnetic zero gas distribution grid increases the effect of hydrophilicity and thereby contributes to the intensification of the drying process. The gas that has passed through the elements 4 and the fluidized bed of material is withdrawn from the pneumo-flap 2 in its upper part and partly together with the material is sent to the chopper 9, in which the material goes to the rotating upper wheel 10 of the disk 10, is entrained by the ventilation flow into the zone of action of the blades 13, then they are sent to the zop of the relative movement of the fingers of And and 17 and the blades 13. The blades drop material into the void of the tooth-like projections located on the periphery of the discs 10. During the grinding process, the free surface increases nce material that causes moisture samoisparenie with the newly exposed surfaces of the n nrotsess intensifies mass exchange. When moving the fingers 11, the blades 12 and 13 relative to the fingers 17, ultrasonic waves occur, accelerating both mass transfer and chemical processes. The pressure forces of the sound waves eliminate the adhesion of particles to the structural elements of the shredder 9. The bright arrangement of the disks 10 contributes to an increase in the path traveled by the material, ensuring the alignment of the residence time of particles by moving the dried material from the non-periphery of the previous disk 10 to the central zone of the subsequent one. The temperature and humidity conditions in the zone of each disk 10 are provided by introducing the coolant from the collector 14 through the openings 15 and the rings 16 having slots in the non-periphery. The insult material is discharged from the lower disk 10 to the discharge, and the spent tenon-media is recycled and cleaned. In the proposed plant, the quality of the material being dried in the corresponding gaseous environment is improved due to the equilibrium distribution of the residual moisture in the product particles and the absence of overheating of the material. It reduces the drying time due to the intensification of the distribution of particles in the gas stream as a result of uniform grinding of the material being dried and the use of a heat carrier with a higher temperature. The installation easily regulates the temperature and humidity modes of drying and creates ultrasonic wave processes that intensify the processes of mass transfer, grinding and eliminate the effect of sticking of particles on the working elements.
