Description

one

Installations for drying high-moisture materials are known, comprising an annular drying chamber with a rotor inside it, a bath for the material being dried, and a mechanism for removing the dry material.

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

This goal is achieved by the fact that on the rotor around its circumference there are installed with the possibility of planetary rotation drums equipped with jackets made of elastic material and end rings, in the radial points of which the longitudinal rods are movably fixed, interacting with the rollers of the mechanism for removing the dry material.

FIG. 1 schematically shows the proposed installation (a cross-section of the drying chamber on the supply side of the coolant); in fig. 2 - the same plan view; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 2; in fig. 5 - drum when interacting with the rollers of the mechanism for removal of dry material; in fig. 6 is a view along arrow B in FIG. 3

The installation contains a heater 1, air ducts 2, a fan 3, a drying chamber 4, a nozzle 5 for air outlet, a rotor 6 with radial spokes 7, drums 8 with jackets 9 of elastic material, rods 10 and end rings 11, a two-tub bath 12 the material being dried with the drain pipe 13 and the screw 14, the rollers 15 on the arcs 16 of the mechanism for removing the dry material, the hopper 17, the drive 18, chain drives 19, 20 and 21, seals 22.

The dried high moisture material, such as enamel frit, is applied to the surface of the elastic shirts 9 of the reels 8 when they are immersed in the upper shaft of the bath 12. The drums 8 rotate at the ends of the radial spokes 7 attached to the rotating rotor 6. Simultaneous rotation of the rotor 6 and

reels 8 is driven from driver 18 via chain drives 19, 20 and 21.

Drying of the material takes place during one rotation of the rotor 6. A heat transfer medium, for example, air heated in the heater 1, is fed through a fan 3 through two air ducts 2 into the drying chamber 4, where it washes the drums 8 in the counter and in the countercurrent and leaves five.

During the passage of the drums 8 over the arcs with freely rotating rollers 15, attached to them in a staggered order, the latter are in contact with the rods 10, causing them to move in the radial grooves of the end rings And and the deformation of the elastic

shirts 9 and thus destroying the layer of dry

material, which is then dumped into the hopper 17.

The feed of the dried material from the bottom rus to the upper russia of the bath 12 is made by a speck 14, and the constant level in the upper rus of the bath 12 is maintained by the drain pipe 13.

Seal the drying chamber with seals 22.

Subject invention

A plant for drying high-moisture materials, for example, an enamel Frit, a gaseous coolant, containing an annular core chamber with a rotor inside it, a bath for the material being dried, and a mechanism for removing dry material, in order to intensify the drying process on the rotor the circles are installed with the possibility of planetary rotation of the drums, equipped with jackets made of elastic material and end rings, in the radial grooves of which the longitudinal rods are movably fixed, and working with rollers of the mechanism for removal of dry material.
