Description

[Detailed description of the invention] The present invention relates to a centrifugal dehydrator, and more specifically, it has a structure in which a balance ring is arranged at the upper end of the dehydration tank, and a dehydration cap is attached to this balance ring. To prevent the volume inside a dehydration tank from being reduced unnecessarily and to easily attach and detach a dehydration cap regardless of the amount of material to be dehydrated.

In conventional dehydrators of this type, the dehydration cap is inserted under the balance ring, so the volume of the dehydration tank is reduced by the height of the balance ring, and the volume of the dehydration tank is reduced by that amount. We have no choice but to reduce the amount of input.

Furthermore, when there is a large amount of material to be dehydrated, it becomes difficult to insert the dehydration cap, and even if it is inserted, it tends to come off due to reaction force.

The present invention eliminates the above-mentioned conventional drawbacks, and examples thereof will be described below.

In the figure, 1 is an outer casing, 2 is a dehydration tank arranged inside the outer casing 1, 3 is a dehydration tank rotatably arranged inside the dehydration tank 2, and has a dehydration hole (not shown) in the peripheral side wall. A motor shaft of a motor (not shown) is connected to the bottom via a coupling.

Reference numeral 4 designates a balance ring fitted into and welded to the upper inner peripheral edge of the dehydration tank 3, and 5 designates a dehydration cap stopper provided on the upper surface of the balance ring 4.

Reference numeral 6 denotes a cover plate having a through hole facing the upper opening of the dehydration tank 3 and whose peripheral edge is placed and fixed on the dehydration receiving tank 2, 7 an inner lid provided with a through hole in the cover plate 6 that can be freely opened and closed, and 8 an inner cover. This is a dehydration lid located above the lid 7 and provided on the upper part of the outer casing 1 so as to be openable and closable.

Reference numeral 9 denotes a switch stand provided on the upper part of the dehydration receiving tank 2, and has a dehydration timer 10.

Next, the dehydration cap stopper 5 will be explained.

The dehydration cap stopper 5 is attached to the case body 4 of the balance ring 4.
A soil wall part 12 having a recessed part 11 formed integrally or integrally with the upper surface part of a and having a recessed part 11 opened in the direction of rotation a during dewatering of the dehydration tank 3; It has an inner side wall part 13 that connects the end and the inner wall of the case body 4a, and a rear side wall part 14 that connects the rear end of the earthen wall part 12 and a radial portion of the upper surface of the case body 4a.

Reference numeral 15 denotes a dehydration cap, which has a handle portion 15a at the center of its upper surface, and a plurality of protrusions 15 at its lower surface along its periphery.
It has b.

The protrusion 15b is inserted into the recess 11 of the upper wall 12, but the radial dimension of the spherical lower end 15C of the protrusion 15b is larger than the width of the recess 11.

Therefore, it is necessary to insert the protrusion 15b while sliding it from the opening direction of the recessed notch 11.

In the above configuration, to perform dehydration work, after putting the object to be dehydrated into the dehydration tank 3, insert the protrusion 15b of the dehydration cap 15 into the recessed part 11 of the dehydration cap stopper 5, and then open the dehydration tank 3. Rotate.

Here, the opening direction of the recessed part 11 into which the protrusion 15b of the dehydration cap 15 is inserted is the direction of rotation of the dehydration tank 2;
The radial dimension of the lower end 15C of the protrusion 15b is the concave notch 1
1, the dehydration cap 15 will not come off while the dehydration tank 3 is rotating.

Since the dehydration cap 15 is installed higher than the balance ring 4, the internal volume of the dehydration tank 3 will not be unnecessarily reduced, and the amount of material to be dehydrated will not be regulated to be too small. .

Further, even when a large amount of material to be dehydrated is put into the dehydration tank 3, the attachment of the dehydration cap 15 is not hindered in any way, and when the dehydration cap is inserted into the dehydration tank while being bent as in the conventional case. Compared to this, the dehydration cap itself can be prevented from being damaged or deformed, and the dehydration cap does not need to be highly flexible at all, which is advantageous in terms of production.

As described above, according to the present invention, the protrusion of the dehydration cap is inserted into the recess of the dehydration cap stop provided on the top surface of the balance ring, and in particular, the opening of the recess is on the side in the rotational direction of the dehydration tank. Since the radial dimension of the lower end of the protrusion is larger than the width of the recessed part, it is possible to prevent the dehydration cap from coming off when the dehydration tank is rotated. The internal volume of the dehydration cap does not decrease in any way by attaching the dehydration cap, and the effect is that the amount of material to be dehydrated can be increased.
