Abstract

VIBRATION DRYER for high-moisture materials, containing a vibration-controlled heated body with a copper bottom and placed inside the body of a screw tray, fastening the loading pipe and discharging device so that, in order to increase productivity, a screw tray before the last upper turn has a connector and the input section of this coil is installed with overlapping of the output section of the last but one turn of the tray and is equipped with a double perforated cone-shaped distributor, with the upper The turn of the tray has a hole larger than the other turns of the latter, is made without an inner bead, and is provided with a number of vertical curved distribution ratios between each other plates, the first of which is attached to the body with one end and the other end in contact with the inner edge of the upper turn.

Od

The invention relates to vibration dryers and can be used in the chemical, metallurgical, construction and other industries associated with the thermal development of high-moisture bulk materials. The purpose of the invention is to increase the productivity of the dryer. FIG. 1 shows a sectional vibrating dryer; in fig. 2 section aa of FIG. The dryer contains a heated housing 1, inside which a split screw tray 2 is fixed, and the heated bottom 3 of housing 1 has a conical shape. A drive bracket 4 is rigidly connected to the base of the housing 1, to which vibro-vibration spruce 5 is attached. On the housing 1 a discharge device 6 is placed. The elastic suspension of the switch 7 is made in the form of springs. A removable cover 8 is attached to the body, fitted with a loading nozzle 9, to the walls of which 10 is attached an upper turn 11 of the screw-shaped tray 2 of greater width than the other turns of the tray 2, with the initial portion of the upper turn 11 located in the plan with overlapping under the ending portion of the last but one turn Tray 2. The upper coil 1 is made without an inner bead, and on top of its bottom there are attached vertical curved distributive plates equally spaced one from the other 12. The first of them, at one end, is replenished to body 1, and the other It is installed in contact with the inner edge of the upper turn 11. A double perforated cone-shaped distributor is attached to the upper coil 11, containing a funnel 13 in the form of a truncated n pore cone, with the base facing up, and placed coaxially and with a gap relative to the co. The base plate 3 of the dryer case 1 with the perforated conical nozzle 14 attached to the funnel 13 can rotate relative to the funnel 13 and with perforation, similar to the perforation performed on the funnel 13. The vibrating dryer works as follows. The perforated tapered nozzle 14 is mounted on the cone of the plug 13 in such a position that the perforation on the nozzle 14 coincides with the perforation on the cone of the funnel 13. When the vibration exciter 5 rotates, a disturbing force occurs under the action of which the drive bracket 4, the housing 1, the lid 8 and the screw Tray 2 performs helical oscillatory movements which are set in amplitude and frequency. The discharge device 6 is set to the Closed position. The wet material enters the dryer through the nozzle 9 of the load placed on the removable 8. From the conical bottom 3, the material is poured off and enters a screw-heated, tray 2, through which it vibrates from the bottom up. From the penultimate turn of the split tray 2, the material is poured onto the upper-upper turn 11 and further along the conveying channels formed by the vertical distribution plates I2, the material is directed to the inner edge of the upper turn 11 evenly along the entire length of its inner edge. At the same time, the material is constantly poured from the inner edge of the coil 11 along its entire length into the funnel 13, over the entire inclined surface of which it is permanently collapsed to its outlet. In this case, part of the material wakes up through the perforated holes, you-. the funnels 13 filled in the cone and in the conical nozzle 14, and enters the conical heated bottom 3. Another part of the material rolls along the walls of the funnel 13 and reaches its outlet opening, through which it enters the conical heated bottom 3 (in the apex area and on the slopes relative to her). Rolling from the entire surface of the conical bottom 3, the material dries out and then re-enters the heated tray 2. This cycle of material movement repeats until the dryer (conical bottom 3 and the screw split tray 2) is being transported along the heated surfaces. will not dry out. After the material has dried, the discharge device 6 is set to the Unload position. In this case, the dry material in the process of pickup311906704
