Description

1257387

The invention relates to dryers for drying bulk materials and may be used in the building materials industry.

The aim of the invention is to increase the quality of drying.

The drawing shows the device, the overall view.

A device for drying loose materials contains an upper chamber 1, made into a cylindrical form 10

gulls, and Bottom, duct 2. A removable lid 3 is installed on the chamber. A hopper 4 is fixed above the chamber. A rotor 5 is placed inside the chamber with a gap relative to it.

The cylindrical shell of the rotor is perforated and attached to the hopper 4 by means of a movably mounted bearing 9, two diametrically opposed vibrating elements 10 are mounted in it. a lattice 11 is attached to a shell 14 with a zigzag face, which is freely supported on a zigzag guide, - reinforced on the bottom box. A barrel 15 is attached to the shell 14, below which a disk valve 17 is attached to the grid with a gap 16 with a gap.

The measure is a drain hole 1B to remove water and waste, and at the top is a hole 19 to exit the spent drying agent.

The device works as follows.

The material being dried is loaded into the hopper 4, from where it enters the perforated rotor shell 5. When the electric motor 13 is put into operation, rotation through gear 12 is transferred to the rotor and all the material under the action of centrifugal forces is distributed on the inside. surface, rotor shells. In this treatment, the surface moisture is removed by centrifugation and removed through the drain hole 18, and its efficiency is increased as a result of vibration vibrations from the vibrators 10, creating horizontal oscillations and from the movement of the gas distribution grid along a zigzag guide box in a vertical plane. The dried material passes through the apertures of the lattice and, with the aid of a funnel 15, is directed towards the distribution valve 17, which rotates together with the lattice. The material is dried in the falling layer in the box 2 in countercurrent of the heated drying agent coming through the channel 6 from the slot 7. The dried material is collected in the discharge hopper 8. The spent drying agent is released from the device through the hole 19.
