Description

The invention relates to a technique for drying loose materials in a vibroanalyzed layer and can be used in the chemical, feed, food and other sectors of the national vegetable industry.

: The purpose of the invention is to increase the quality of drying by eliminating stagnant zones.

I Figure 1 shows the vibrating dryer, a slit; figure 2 - section aa in figure 1; in FIG. 3, the execution of I of the guide elements in the form of spi-rial grooves, option; FIG. figure 5 - section; cut BB in figure 4.

: The vibratory dryer contains a suction chamber 1 with built-in internal transporting screw device 2, loading 3 and unloading 1 tray 4, valve 5, pipe 6 I inlet and pipe 7 draining heat 1siter connected to camera I post -: a device of flexible elements 8. In the lower part of the chamber I there is a gas: distribution grid 9 inclined towards the discharge chute 4.

The camera is mounted on an elastic suspension30

10 and provided with an exciter I); The end walls 12 of the chamber 1 are additionally equipped with conical inserts 13, between which a conveying screw device 2 is placed. Conical inserts 13 are 35 filled with mixing elements 14 extending from the top of each insert 13 to its periphery in the opposite the direction towards the opening of the mixing element 40 14 of the opposite conical insert 13. The mixing elements 14 can be made in the form of spiral channels (Fig. 3) or spiral blades (Fig.4) .45

Vibration dryer works as follows.

When the vibration exciters 11 are located in the plane, the passage of the porting screw device moves the mat's inner layers to the right end wall 12 with a conical insert 13, with a stirring element 14, for example, a spiral channel. Thus, the tapered insert 13 is subjected to pressure by the material transported by screw screw 2. Rotated at the right end of the wall, the material is transported along spiral wires from the center of the region of the layer to the upper layers. In this way, a cluster of material is formed at the right end station under the action of vibration of the material to a uniform distribution over the entire length of the drying chamber, as a result of which the upper joints go to the left end wall which is made similar to the end wall 12, but its back channel is open with respect to the spiral channel of the right end wall, therefore, it captures the upper material and transports it to the center of the layer to the screw device, thus lowering the level of the material from the left end wall

Claims (2)

Invention Formula I. Vibration dryer for persistent materials, containing a shielding chamber with a transport screw screw placed therein, loading and unloading trays and supply pipes and heat carrier, characterized in that, in order to improve the quality of drying by stagnant zones, the end chambers were equipped with provided with cic inserts, made oppositely directed mixing elements, with through the center of mass of the oscillating su-50 smaller base conical The latter is connected to oscillations along a circular trajectory. The material placed in the drying chamber 1 as a result of vibrotransport makes a rotary circular motion 55 opposite to the direction of rotation of the vibration exciters. The transverse is located opposite, and the transport device is placed. 2. The dryer according to claim 1,0 tl so that the elements are mixed in the form of sp grooves or blades. 0 five thirty 0 25 35 40 45 , The porting screw device 2 moves the inner layers of material to the right end wall 12 provided with a conical insert 13, with a mixing element 14, for example, with a spiral channel. Thus, the right conic insert 13 is constantly subjected to the pressure of the material transported by the screw device 2. Rotated at the right end wall, the material is transported along spiral channels from the central region of the layer to the upper layers. Thus, an accumulation of material forms at the right end wall 12. But under the action of vibration, the material tends to be evenly distributed along the entire length of the drying chamber, as a result of which the upper junction moves to the left end wall | 2, which is made similar to the right end wall ,, 12, but its spiral channel is open in the opposite direction relative to the spiral the channel of the right end wall 12, therefore, it picks up the upper layers of the material and transports it to the central region of the layer to the transport screw device 2, thus lowering the material level at the left torus central wall 12. Invention Formula I. Vibration dryer for dispersed materials, containing a drying chamber with a transporting screw device placed inside it, loading and unloading trays and nozzles for supplying and discharging the heat transfer medium, characterized in that, in order to increase the quality of drying by eliminating stagnant zones, the end walls chambers dsFpolnenr equipped with conical inserts made with oppositely directed mixing elements, while smaller conical bases The wok is located opposite, and between them there is a transporting screw device. 2. The dryer according to claim 1,0 of aphid is inherent in that the mixing elements are made in the form of spiral grooves or blades. 1D673D4 Aa 1b Fy S- (f Fi9.2 bb lit fPuf.5
