Embodiment Construction

[0021] A rotating hub of a rotary dryer with a flue gas deflector, comprising: a rotary hub 3 , a deflector 4 , and a fire box 5 .

[0022] The smoke inlet 8 is in the tangential direction at the bottom of the fire box 5, and the deflector 4 is distributed in a spiral shape on the outer wall of the rotating hub 3; the direction of rotation of the deflector 4 depends on the rotation of the rotating hub 3;

[0023] The addition of deflectors is a new design for the dryer hub, which solves the problems that the drying effect of the dryer cannot meet the process requirements and the qualified rate of finished products is low for many years. The drying residence time in the rotating hub improves the production efficiency.

[0024] When adding deflectors,

[0025] ① Before the assembly and welding of each section of the hub 3 is completed and installed with other components, draw a spiral line on the hub 3 according to the figure;

[0026] ② Spot weld the deflector 4 on the hub 3 ...

Abstract

The invention discloses a rotary dryer rotating hub with a flue gas guide plate. The rotary dryer rotating hub is characterized in that the high-temperature flue gas guide plate is additionally arranged on the outer side of the dryer rotating hub; and by guiding a flue gas flow to flow around the rotating hub, the heat exchange time with the rotating hub is increased, and the high-temperature fluegas is uniformly distributed on the rotating hub. With the arrangement of the flue gas guide plate, the problems of low qualified rate of finished products of a dryer, uneven distribution of high-temperature flue gas outside the rotating hub and the like are effectively solved.

Description

technical field [0001] The invention relates to a rotary dryer equipment. The equipment is mainly composed of a rotating hub, a transmission system and a fire box. The rotating hub is driven by the transmission system to rotate. The inside is the wet granular material to be dried, and the outside is introduced between the fire box. A stream of high-temperature flue gas heats the rotating hub and then enters the rotating hub to fully contact and heat the wet material, so as to achieve the purpose of drying the wet material. The rotating hub of the dryer with deflector can effectively guide the high-temperature flue gas entering between the fire box and the rotating hub to flow around the outer wall of the rotating hub and maximize heat exchange with the outer wall of the rotating hub, shortening the drying time for wet materials , while the length of the hub can also be shortened accordingly. Background technique [0002] For many years, the rotary dryer widely used in the c...
