Description

[0001] Waste drying apparatus [

The present invention relates to a waste drying apparatus, and more particularly, to a waste drying apparatus capable of drying and crushing industrial waste containing moisture.

Generally, industrial wastes containing moisture are dried and treated.

There is a need for a drying apparatus that removes moisture from industrial wastes containing a large amount of water to reduce the weight and volume of the waste.

A casing member having a predetermined space through which hot air is supplied and having an inlet through which waste is introduced and an outlet through which dried waste is discharged; A rotating shaft member installed through the center of the casing member and rotationally driven; A plurality of first disk members coupled to the rotating shaft member at a predetermined interval concentrically and rotated together with the rotating shaft member to transfer the dropped waste outwardly; A plurality of second disk members which are provided between the first disk members and are coupled to the rotating shaft member to rotate together and have through holes through which the waste dropped at the central portions passes; A first guide means including a first support bar provided at an upper portion of each of the first disk members and curved at a predetermined curvature, a plurality of first braids supported at a predetermined interval on the first support rods and guiding the waste in an outward direction, ; A second support bar provided at an upper portion of each of the second disk members and curved at a predetermined curvature, a second guide supported by the second support bar at a predetermined interval and including a plurality of second blades guiding the waste in the rotation center direction, A drying device has been developed which is characterized in that it comprises:

However, in the conventional drying apparatus, there is a disadvantage that a part of the waste to be dried is not dried due to lack of a process of shredding the waste. In addition, there has been an inconvenience that the re-drying must be performed as the waste is injected and discharged in a lump state.

In the conventional drying apparatus, the second disk member rotates along the rotating shaft member and drops into the through hole formed at the center. Since the waste accumulates on the outer side of the second disk member, that is, in the narrow gap separated from the casing member, The disk member is not circulated smoothly, and there is an inconvenience that the management of the manager must be steadily maintained.

In addition, in the conventional drying apparatus, the first guide means and the second guide means merely guide the waste, and the waste can not be mixed so that the waste can be dried, so that the drying time is lengthened, There was.

First, the case 10 is formed with a charging port 12 through which waste is injected and a discharge port 14 through which the dried waste is discharged.

The inlet port 12 is formed in the upper portion of the case 10 and the outlet port 14 is formed in the lower portion of the case 10.

The rotating shaft 18 is provided through the center of the case 10 and is rotated by the driving of the first driving part 16. [ A first disk member 20 and a second guide means 50, which will be described later, are coupled to the rotary shaft 18 and are integrally rotated.

2, the first disc member 20 is coupled to the rotating shaft 18 and rotates integrally.

The first disc member 20 is preferably formed to have a radius smaller than the shortest distance from the inner surface of the case 10 from the rotary shaft 18 so as to be separated from the inner circumferential surface of the case 10 so as to allow the waste to fall outwardly , And are formed at a plurality of spaced apart intervals.

6, the first disk member 20 rotates together with the rotary shaft 18 and the waste is separated from the space between the case 10 and the outer side to separate the second disk member 30, It may be formed to be inclined downward from the rotation shaft 18 toward the outer end.

3, the second disk member 30 is provided between the first disk members 20 and is fixed to the inner circumferential surface of the case 10. As shown in FIG. Further, the second disk member 30 is engaged with the rotation shaft 18 but is not coupled with the rotation shaft 18 together with the rotation shaft 18.
