Abstract

The invention relates to a roller type drying and sintering or roasting device which comprises a kiln body and a drive device. A drying roller comprises a kiln body outer shell, a net-shaped outer sleeve and a net-shaped inner sleeve from outside to inside in the radial direction of the drying roller. The inner wall of the kiln body outer shell and the outer wall of the net-shaped outer sleeve are connected through a plurality of sliding drive shifting blocks evenly distributed in the circumferential direction, and rotary drive is carried out. A powder chamber is formed by a space between the kiln body outer shell and the net-shaped outer sleeve. The net-shaped outer sleeve and the net-shaped inner sleeve are connected through a plurality of net-shaped partitions spirally extending in the length direction of the kiln body. A space between the net-shaped outer sleeve and the net-shaped inner sleeve is divided by the partitions into a plurality of drying or roasting (sintering) material chambers distributed in the circumferential direction. An inner sleeve air chamber is formed by a space in the inner sleeve. The device has the beneficial effects that material drying is even, thorough and fast; the manmade pellet (spherical block) damage rate is low; the device investment is reduced; the productivity is greatly improved; and energy saving and emission reduction are realized.

Description

technical field [0001] The invention relates to a drying device, in particular to a drum-type device capable of drying, sintering or roasting. Background technique [0002] The existing drying equipment on the market mainly includes tower (shaft furnace) dryers, drum dryers, crawler fluidized bed dryers, vertical flash or boiling dryers and other devices. [0003] The tower (shaft furnace) dryer is mainly used for drying granules or pellets, and the drying effect is not very uniform and the drying is not thorough. [0004] The tumble dryer can be used for drying solid and powder materials, but the drying of artificial pellets is not thorough, the ball breaking rate is high, and the artificial pellets cannot be sintered and roasted. [0005] Caterpillar fluidized bed dryers, such as mesh belt machines, chain plate machines, grate machines and other crawler drying and sintering machines can only be used for drying and sintering of lumps and pellets, but the cost of sintering ...
