SU1627793A1 - Drier for wood chips - Google Patents

Abstract

The invention relates to a drying technique, can be used in the production of chipboard, and makes it possible to increase the uniformity of the drying process. Particles of different sizes enter through the loading device 6 into the gap formed by mixing, the device 2 and the stationary drum 1, and re-light through the drying zone in the direction of the conical insert 8. On the way, the wood particles interact with the high-speed flow of heat carrier flowing through gas nozzle with adjustable dampers 4. Dried wood particles from the drying zone enter the inside of the shredder 9, made in the form of perforated glass 10. The particles are crushed during the interaction of pop plystryn 14 with blades 15. The perforated cup 10 with the plates 14 on the inner surface rotates at different speeds and directions relative to the blades m 15 mounted on the flank 16. The crushed particles are transported through the holes of the perforated cup 10 through the openings of the perforated cup 10 between the latter and the drum I wall, from where the particles are moved by screw 13 to the exhaust coolant outlet nozzle 5 and output to a further separation in the form of a gas suspension. 3 il.

Claims (1)

Claim A wood particle dryer containing a fixed drum with a mixing body located in it, a gas supply system with a gas nozzle with guide flaps connected to the side surface of the drum along the length of the mixing body, a coolant pipe, a material loading and unloading device, is distinguished by the fact that, in order to increase the uniformity of the drying process, the drum is additionally equipped with an insert in the form of a truncated cone mounted at the outlet of the mixing organ and mounted on the bar wall the banana with a large base and a grinder made in the form of a perforated cup mounted coaxially on the hollow shaft, on the outer surface of which there is a screw auger, and on the inside there are pairs of plates interacting with the side surfaces of the blades mounted on an individual shaft, while the conical insert is paired with a perforated glass, and the end of the mixing organ is placed coaxially with the conical insert and repeats its profile.
