Description

[Detailed description of the invention] [Industrial application field] The present invention removes moisture adhering to agricultural products, such as dew on tea leaves and moisture adhering after washing.
This invention relates to a dewatering tank of a reversible and take-out type dehydrator, which is rotated at high speed to drain water, and then the entire dehydrating tank is turned over and taken out.

[Conventional technology and problems]

In the case of a reversible extraction type dehydrator, the entire dehydration tank is turned over to take out the material to be processed inside, but some of it may stick to the inner wall of the dehydration tank and not be taken out.

This is centrifuged to the inner wall of the dehydration tank,
Since the quantity is not so large, the moisture that exists in the form of droplets on the inner wall of the dehydration tank rather than passing through the holes drilled in the dehydration tank causes some of the material to be processed to stick to the inner wall of the dehydration tank. This is because.

In such a case, when the dehydration tank is rotated to perform the next dehydration, the weight of the remaining adhesion causes the dehydration tank to rotate eccentrically, and furthermore,
If the following is introduced during the eccentric rotation, the eccentric rotation will be further accelerated, and the rotation will become dangerous and cause various troubles.

With this, there is no hope for smooth dehydration work,
The life of the dehydrator will also be shortened.

[Purpose of invention]

The present invention was developed in view of the current situation, and it isolates the dehydration tank and the object to be processed, thereby cutting off the adhesion force caused by water droplets, and furthermore, when the rotation of the dehydration tank stops, the material inside is removed. Allow the processed material to move slightly relative to the dehydration tank, and when reversing and taking out,
This prevents the objects to be treated from remaining in the dehydration tank.

[Summary of the idea]

Therefore, in order to achieve the above object, the present invention provides a dehydration tank that is housed in a reversible protective outer casing and receives the rotation of a motor attached to the outside of the outer casing, and a mesh bag is installed in the dehydration tank. It is characterized by a structure that prevents adhesion during reversal and extraction in a dehydration tank that is double-installed.

〔Example〕

Next, the present invention will be explained based on an illustrated embodiment in which only the main parts centering on the dehydration tank are shown.

The dehydration tank 1 has a cylindrical outer shape with an open top and a bottom, and is housed in a protective outer casing 8 that is reversible by an appropriate drive type, and a motor 9 mounted on the outside of the outer casing, for example, on the outside of the bottom. is fixedly supported on a shaft 10 of the outer casing 8, and is rotatable at high speed within the outer casing 8.
It can also be reversed freely.

Inside the dehydration tank 1, there are double bottomed cylindrical net bags made of resin such as nylon.

In this embodiment, when installing the net bags inside the dehydration tank 1, the upper end peripheries 2a, 3 of the inner net bag 2 and the outer net bag 3 are
a, the bottom center 2b, 3b, and the bottom periphery 3 of the outer net bag 3
c and were fixed at positions corresponding to each part of the dehydration tank 1.

In addition, when fixing the upper edge edges 2a and 3a, the inner ring 4, which also partially serves as a weight counter, is used to press down, and when fixing the bottom center 2b and 3b, a bolt is hidden on the shaft mounting boss 5. In order to fit the cap 6 and further fix the bottom circumferential edge 3c of the outer net bag 3, attaching strings 7 extending from appropriate locations on the bottom circumferential edge 3c are attached to holes drilled in the dehydration tank. I decided to tie it to secure it.

Therefore, to explain the operation using a dehydrator equipped with such a dehydrator tank 1, the process from inputting the material to be processed, for example, tea leaves to dehydration, is no different from that of a conventional dehydrator.

At the same time as the dehydration is completed, the rotation of the motor 9 is stopped, and a brake is usually applied to the motor, and the rotation of the dehydration tank 1 is accordingly stopped.

At this time, inside the dehydration tank 1, the rotation of the dehydration tank 1 is suppressed by a brake etc. from the motor 9 side, but the objects to be processed inside try to maintain rotation for a while due to inertia. For this reason, the tea leaves try to pull the inner mesh bag 2 due to frictional force with the inner mesh bag 2, etc.
The inner wall of the dewatering tank 1 tends to stop together with the outer mesh bag 3 due to frictional force with the outer mesh bag 3.

The forces that try to pull each other between the tea leaves, the inner mesh bag 2, the outer mesh bag 3, and the inner wall of the dehydration tank 1 are centrifuged to the inner wall of the dehydration tank, but the amount is not large, so They are made even stronger so that they can stick to each other by the water that is present in the form of water droplets on the inner wall, rather than coming out through the holes in the tank.

However, since there are double mesh bags 2 and 3 between the tea leaves and the inner wall of the dehydration tank 1, the water droplets present in these bags do not act strongly enough to directly stick the tea leaves and the inner wall of the dehydration tank 1. If the dehydration tank 1 is turned over, the object to be processed can be taken out very smoothly without any residual adhesion, because the relative shift at the time of stopping will completely cut off the sticking force due to moisture. . In particular, if the inner mesh bag 2 and outer mesh bag 3 are made of resin, the friction between them is extremely low.
Since the relative deviation at the time of stopping is severe, it becomes easier to separate.

If no processed material remains attached to the dehydration tank 1, eccentric rotation will not occur in the next dehydration, and the dehydration work can be continued smoothly.

The present invention has the configuration described above, and in this embodiment, the most preferable fixing method is given as an example, but when installing the net bag inside, the method of this embodiment is Needless to say, it is not limited to. For example, the inner net bag may be fixed at the intermediate depth, or only at the center of the bottom.

In addition, the structure of the dehydrator itself is basically a cylindrical dehydrator with an open top, which rotates at high speed to drain water, and then turns over to take out the processed material inside. It can be applied with any type of dehydrator.

[Effect of idea]

The present invention has the above-mentioned configuration, isolates the dehydration tank and the object to be processed, cuts off the adhesion force caused by water droplets, and furthermore, when the rotation of the dehydration tank stops, the object to be processed inside is slightly removed. Since it is designed to move relative to the dehydration tank, when the dehydration tank is reversed and taken out, there is no possibility that the material to be treated remains attached to the dehydration tank, and the dehydration work can be carried out smoothly.
