Description

  The present invention relates to a dehydrator, and more particularly to a dehydrator capable of continuously removing moisture from cereals such as washed soybeans and automatically and continuously recovering dehydrated matter.

Conventionally, a dehydrator contains a material to be dehydrated in a rotating basket, and spins and spins off moisture by centrifugal force. The dehydrated material in the rotating basket is taken out from the rotating basket. Yes.
As a vibration dehydrator, dehydration is performed with a vibrating sieve as in Patent Document 1, and the material to be dehydrated is sent to the next process part by vibration.
JP-A-10-57726

In the conventional centrifugal dehydrator, it takes time to take out the material to be dehydrated from the rotary basket after dehydration, and it is difficult to perform continuous dehydration. Further, the vibration dehydrator has a drawback that it is difficult to perform sufficient dehydration.
The present invention provides a dehydrator that continuously receives dehydrated materials delivered from a washing machine, dehydrates at high speed, and automatically automatically collects dehydrated items continuously, It is an object.

  The specific contents of the present invention are as follows.

  (1) A collection guide is provided at the upper periphery of the water receiving tank provided on the base, and a dewatering basket is provided in the water receiving tank so as to be pivotable. A flange is formed at the upper end of the peripheral wall, and the flange is set to cover the upper end of the dewatering tank with a predetermined interval. In the dewatering bowl, the lower end is close to the bottom with a predetermined interval. Thus, the hopper is disposed in a non-contact manner, and the dehydrated material thrown in from the hopper is dehydrated by the rotational centrifugal force of the dewatering basket and rises by the centrifugal force along the inner wall surface, and is collected by the collection guide. Configured to be a dehydrator.

  (2) The dewatering basket is supported on an upper part of a rotating shaft disposed through the bottom of the water receiving tank. The rotating shaft is connected to a prime mover through a transmission mechanism, and the rotation speed of the dewatering basket can be changed. The dehydrator described in (1), which is configured as described above.

  (3) The dehydrator according to (2), wherein the speed change of the dewatering trough is based on inverter control of a prime mover.

  (4) The dehydrator according to (2), wherein the speed change of the rotational speed of the dehydrator is by a speed change unit disposed in a transmission mechanism interposed between the rotating shaft and the prime mover.

  (5) The dehydrator according to any one of (1) to (4), wherein the dewatering bowl is configured to be able to replace the dewatering bowl having a different form with respect to the rotating shaft.

  The present invention has the following effects.

In the dehydrator according to the invention described in the above (1), the material to be dewatered put into the dewatering basket from the hopper is dewatered by the centrifugal force by the rotating dewatering basket, and the inner wall circumference of the inclined dewatering basket by the centrifugal force It gradually moves upward along the surface, reaches the upper end of the dewatering basket, is flipped outward, and is continuously collected by the collection guide.
As a result, dehydration and recovery are performed automatically.

  The dehydrator of the invention described in the above (2) can adjust the dehydration degree and the recovery rate by adjusting the rotation speed of the dehydration basket, and can immediately respond to changes in the dehydrated matter. .

   The dehydrator of the invention described in (3) can smoothly control the rotation speed by inverter control of the prime mover.

   In the dehydrator according to the invention described in (4) above, since the transmission mechanism is provided in the transmission mechanism, the rotational speed can be switched immediately even if the prime mover is the same.

   The dehydrator of the invention described in the above (5) can be dehydrated by replacement by selecting a dewatering bowl suitable for the material to be dehydrated.

  The upper part of the dewatering trough has a large diameter, a flange is formed at the upper end, and the flange is disposed in a covering shape at the upper end of the water receiving tank.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a dehydrator according to the present invention. In the drawing, the dehydrator 1 is provided with a water receiving tank 3 on a base 2. Reference numeral 3a in the figure denotes a drain outlet. A collection guide 4 is fixed to the upper periphery of the water receiving tank 3.

The upper end portion of the collection guide 4 is set at a position higher than the upper end surface of the water receiving tank 3, the lower circumferential portion is inclined to one side, and a discharge port 4a is formed at the lower end portion.
A bearing 5 is fixed to the inner bottom of the water receiving tank 3, and a rotary shaft 6 is rotatably disposed on the bearing 5. A lower portion of the rotary shaft 6 is connected to the prime mover 7 through an arbitrary transmission mechanism 7a. ing.

The bottom of the dewatering basket 8 is fixed to the upper part of the rotating shaft 6, and the rotating shaft 6 rotates at high speed. The form and material of the dewatering basket 8 are arbitrary.
A flange 8a is formed at the upper end portion of the dewatering basket 8, and the flange 8a portion is set to cover the upper end of the water receiving tank 3 with a predetermined interval.

In the dewatering basket 8, a hopper 9 is disposed with a bottom portion close to the bottom of the dewatering basket 8 at a predetermined interval, and the upper portion of the hopper 9 is higher than the upper end surface of the collection guide 4. Set to position.
In the above configuration, for example, soybeans are washed in a washing machine (not shown) and dehydrated with a vibration sieve or the like is automatically put into the hopper 9.

  When the dewatering basket 8 is rotated by the operation of the prime mover 7 and the material to be dehydrated is introduced into the hopper 9 from a washing machine (not shown), the lowered material to be dehydrated reaches the bottom of the dewatering basket 8 and the rotational centrifugal force of the dewatering basket 8 When the debris 8 hits the inner wall surface of the dewatering basket 8 and is dehydrated, it moves upward on the slope of the inner wall peripheral surface by centrifugal force and rises up to the upper end of the dewatering bowl 8 and is bounced outward to collect the guide. 4 is lowered and recovered from the discharge port 4a.

The dewatering basket 8 may be rotated after a material to be dehydrated is put in the hopper 9 in advance. When the material to be dehydrated at the bottom of the dewatering basket 8 moves upward along the inner wall surface by centrifugal force, the material to be dehydrated in the hopper 9 naturally falls.
As a result, the dehydration and the recovery can be automatically made continuous.

If the inclination of the wall surface of the dewatering basket 8 is gentle, the dewatering rate is increased, so that the dewatering rate is lowered. Accordingly, the dewatering efficiency is higher when the inclination of the wall surface of the dewatering basket 8 is kept steep and the rotational speed is increased.
As a means for adjusting the rotational speed of the dewatering basket 8, for example, the prime mover 7 can be configured to be variable by inverter control. The transmission mechanism can be provided with transmission means.

The present invention is not limited to the above-described embodiments, and can be appropriately changed in design according to the purpose. This dehydrator can be combined with an automatic washer and a vibratory simple dehydrator to automate.
Further, the dewatering basket 8 can be configured such that different items such as the roughness of the eyes and the inclination of the wall surface can be attached to and detached from the rotating shaft 6 and can be arbitrarily replaced according to the purpose. In that case, the hopper 9 can also be configured such that the mounting height can be adjusted.

  This dehydrator is suitable for dehydration after washing the granular material, and particularly suitable for dehydration of millet.

It is a front view of the dehydrator concerning the present invention.
