DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifugal dehydrator, and more particularly to an improvement in an inner basket used for dehydrating a container-shaped dehydrate.

[0002]

2. Description of the Related Art As is well known, when dewatering a container-shaped dewatered material using a centrifugal dewatering machine, the following method has been adopted because water tends to remain inside.

(1) Dehydration is performed using an inner basket 1 as shown in FIG. In this case, first, the dewatered material is dewatered while rotating outward from the center object along the slope provided in the inner basket by rotation.
Next, the rotation is stopped and the dehydrated material is returned to the center along the slope. When the direction of the dehydrated material changes along with this movement, the container-shaped dehydrated material is dehydrated by repeating rotation and rest.

(2) FIGS. 2 (A) and 2 (B) show a case where a small number of varieties are handled, and a method of dehydrating by dividing and arranging a plurality of inner baskets 2a, 2b, 2c and 2d. Note that an inclined plate 3 as shown in FIG. 2B is provided inside each inner basket. Also in this case, dehydration is performed in the same procedure as in the above (1).

[0005]

However, the conventional centrifugal dehydrator has the following problems. That is, in the case of the above (1), it is preferable to perform a large amount of dehydration at once, but the efficiency is low for a small amount of many kinds of dehydration. On the other hand, the case (2) is suitable for the production of a large number of varieties in small quantities, but the dewatering efficiency is poor, and complete dehydration cannot be performed without manual operation.

[0006] The present invention has been made in view of the above circumstances, the efficiency of dehydration of a small number of varieties is good, and even when dehydrating container-shaped dehydrated, it is necessary to manually forcibly agitate during the dehydration. The purpose is to provide a centrifugal dehydrator that does not.

[0007]

Means for Solving the Problems The present invention provides a dewatering tank,
In a centrifugal dehydrator having a plurality of inner baskets arranged along the circumferential direction in the dewatering tank, the inner basket has an input port for inputting dehydrated material at an upper portion and a dehydrated material at a lower portion. A housing having a take-out opening for take-out, and a rotating shaft-side end of the dewatering tub is inclined and arranged in the housing so as to be positioned lower than an outer end thereof. A first inclined plate on which the dehydrate is moved by the generated centrifugal force, and a second inclined plate disposed in the housing below the first inclined plate and substantially parallel to the first inclined plate, on which the dehydrated substance slides down when stopped And a centrifugal dehydrator comprising:

[0008]

The case where the first and second inclined plates are alternately arranged two by two in the inner basket as shown in FIG. 4 will be described.

(1) First, a dehydrated product is put into the inner basket through the inlet, and placed on the uppermost inclined plate in the inner basket. Set so that the side plate faces the rotation axis of the centrifugal dehydrator. Here, the number of rotations, the rotation time, the stop time, and the number of rotation-stop cycles are set in the centrifugal dehydrator in advance.

(2) When the centrifugal dehydrator rotates, the dehydrated material on the uppermost inclined plate moves upward along the inclined plate due to the centrifugal force, and the dehydrated material is inclined secondly from the gap between the inclined plate and the side plate. Fall to the board. When the rotation stops, the dewatered material moves down the inclined plate, and falls to the third inclined plate due to the gap between the inclined plate and the side plate.

(3) When the centrifugal dehydrator rotates again, the dehydrated material on the third inclined plate moves upward along the inclined plate by centrifugal force in the same manner as described above, and the dehydrated material is moved between the inclined plate and the side plate. After falling from the gap to the fourth inclined plate and stopping rotation, it falls from the inclined plate to the bottom plate.

(4) After the rotation-stop cycle is completed at 4 c / s, the door is opened and the dehydrated product is taken out of the inner basket. As described above, the direction of the dehydrated material changes many times while rolling while moving from the uppermost inclined plate to the lowermost bottom plate, and the moisture of the dehydrated product is dehydrated by centrifugal force.
