Description

The invention relates to drying and can be used in the woodworking industry.

The aim of the invention is to intensify the drying process.

The drawing shows a vibrating dryer, a longitudinal section.

The vibrating dryer contains a vertical chamber 1 with a bracket 2, a tube 3 perforated below for supplying heat transfer fluid and springs 4 on which a vibrotransporter 5 is mounted. Chamber 1 is mounted on the vibrating supports of the lower part and is equipped with a discharge funnel 7 with an opening 8. On the beam 9 there is an elec. Tromagnet 10 vibrodrive. The anchor 11 is attached to the bottom of the vibrotransporter 5, which is made with a tapered extension 12 in the upper part of the chamber 1. The vibrating conveyor 5 is provided with a multi-turn tray 13 on the tapered expansion section 12, with the perforations of the tray 13 having an increasing diameter. At the bottom of the vibrotransporter 5 is installed inclined - the lid 14, the transition into the tray 15. At the bottom of the vibrotransporter 5 there are a series of holes 16, and at the bottom of the pipe 3 there are a series of 17 holes for the heat carrier exit. In the upper part of the conical expansion 12 there are cylindrical springs 18, which are attached to the upper lid 19. On the lid 19, a feed funnel 20 is installed. On the outer part of the feed funnel 20, sealing elements are installed in the form of a series of washers 21 that perform the role of sealing labyrinths to prevent flue gases in the space between the feed funnel 20 and pipe 3. Inside chamber 1, a tray 22 is fixed in its upper part, and in its midst and lower part is a multi-pass tray 23. To prevent losses to the surrounding Wednesday chamber 1 is made with a heat insulating layer 24.

Vibration dryer works as follows.

Small fractions of wood waste are poured into the feed hopper 20. The supply voltage to the electromagnet 10 is turned on, resulting in measles 11 along with vibJO

cl

the rotor transporter 5, the trays 15 and 13 and the conical expansion 12 begin to vibrate, while the waste enters the space between the tube 3 and the vibrating conveyor 5 and moves towards the inclined cover 14. At the same time, coolant is supplied through the tube 3 that comes out through the holes 17 and with wood waste enters the space between the trays 15, 13, 22 and 23. The wood particles due to the directional vibration of the vibrating conveyor 5 rise up the tray 15, then the transition into the tray 13. The presence of perforations in the trays 13 allows dry fine they are sent down to the funnel 7 by the particles. Larger fractions rise to the upper part of tray 13, from where they fall into tray 22. From tray 22, waste is poured into tray 23 (trays 22 and 23 are chosen together with camera 1 to counter the vibrating conveyor 5). The wood waste is moved to the lower part of chamber 1 and through opening 8 is discharged from the dryer due to: ibration.

Drying of wood waste begins in the space between pipe 3 and vibrating conveyor 5 and continues on trays 15, 13, 22 and 23, as well as in the process of sifting through perforations and pouring from tray 22 and 23. The drying process proceeds by heat conduction and convection. Removal of exhaust gases is carried out in the upper part of chamber 1 through openings (shown in the drawing). Due to the presence of a conical expander 12 and holes of varying diameter on each subsequent turn of tray 13, large fractions of wood waste are for a longer time in chamber 1, and small waste is immediately transferred to multi-way tray 23, sifted through openings in tray 13. In the hopper 20 a natural compaction of wood waste is formed, which prevents the exit of flue gases, thus a certain condition is the presence of a certain amount of small fractions of wood waste in the feed hopper 20. .

Vibration dryer for wood

waste allows drying of polydisperse materials, for example wood waste, fractions of which range from 1000 µm to 10-20 mm.
