ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a moisturizing equipment for moisturizing an object to be moisturized, which object mainly contains a sheet-shaped substance (for example, vinyl sheet).
Conventional moisturizing equipments will be described with reference to FIG.
1
.
Installed at a bottom of a vessel
12
is an agitating vane
13
for rotation in a rotating direction
14
. A water addition unit
15
is installed on one side of an upper portion of the vessel
12
, a supply port
16
for an object is provided on the other side of the upper portion of the vessel
12
, and a recovery port
17
for the object is provided on a lower side of the vessel
12
.
In such moisturizing equipment, the object is supplied into the vessel
12
from the supply port
16
in a direction
18
of supplying, water is added into the vessel
12
from the water addition unit
15
, and the agitating vane
13
is rotated.
Then, the object is moisturized and discharged from the recovery port
17
in a direction
19
of recovery.
Such conventional moisturizing equipments are disadvantageous in that the moisturizing efficiency is extremely decreased when a sheet-shaped substance is contained in an object.
Concretely stated, an object remains within the vessel
12
such that a sheet-shaped substance is twined around the agitating vane
13
and covers the recovery port
17
of the vessel
12
, thus resulting in reduction in the processing capacity of the moisturizing equipment. In particular, when an object is to be continuously moisturized in great quantity, it is necessary to efficiently control a series of processes including the process of supplying into the vessel
12
of the object, the moisturizing process, and the recovering process. However, it is possible that the reason for reduction in the processing capacity of the moisturizing equipment, caused by a sheet-shaped substance is generated in the respective processes described above. In particular, when an object is a substance of many kinds, such as a sheet-shaped substance and so on, like waste, it is extremely difficult to enhance the moisturizing efficiency of the whole object. Further, in the case where the moisturizing processing is needed as a preliminary process in recycling and waste disposal, it is not possible to realize suitable recycling and processing.
In this manner, since it is difficult in the conventional moisturizing equipments to moisturize an object, which contains a sheet-shaped substance, it has been earnestly desired to develop a moisturizing equipment capable of operating even under the above-mentioned troublesome conditions.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a moisturizing equipment capable of moisturizing an object to be moisturized, with high efficiency even when the object contains a sheet-shaped substance or the like.
It is another object of the invention to provide a moisturizing equipment, in which an object is prevented from remaining in a vessel.
According to the invention, there is provided a moisturizing equipment having an addition unit for adding a moisturizing medium to an object to moisturize the object, the equipment comprising a hollow rotating drum provided obliquely, and a size classification unit provided on a part of the rotating drum, and wherein the object is supplied from an opening on an upper portion of the rotating drum, so that an object having at most a predetermined size is discharged from the size classification unit while an object having a larger size than the predetermined size is discharged from an opening on an underside of the rotating drum.
