JPS583743B2 - grain washer - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain washing machine that automatically washes and discharges rice and other grains.

Washing rice and other grains is still done by hand even today, when household labor has become more streamlined.

This process is not only troublesome because it involves repeating water injection, rinsing, and draining, but it is also troublesome especially when the water is cold, such as in winter.

In the present invention, a spiral body connected to a prime mover is inserted into a straight pipe made of a mesh body, a separator is rotatably installed at the top of the straight pipe, and a scattering chamber is provided between the separator and the rotating plate. By providing a grain washer that is rotatably installed, has an inlet at the bottom of the straight pipe, and an outlet in the scattering chamber, it automates the washing of grains and makes the complicated work easier. The purpose is to

The present invention will be described based on the illustrated embodiment. Reference numeral 1 denotes a spiral body connected to a motor 2 via a coupling 3, and is penetrated into a straight pipe 5 vertically installed in a container 4.

A mortar-shaped separator 6 is rotatably installed on the upper part of the straight pipe 5 via a bearing 7 made of a synthetic resin with a small coefficient of friction, such as fluororesin.

A mesh is provided on the circumferential side of the separator 6.

Reference numeral 8 denotes an entrance provided in the separator 6.

A scattering chamber 9 is provided in the upper part of the separator 6, and a flat rotary plate 10 is rotatably provided.

11 is a grain inlet provided at the lower part of the straight pipe 5, 12 is a grain outlet provided in the scattering chamber 9, and 13 is an outlet pipe attached to the outlet.

Numeral 14 is a water supply pipe connected to a water distributor 15, from which it is divided, one opening into the upper part of the straight pipe 5, and the other opening into the scattering chamber 9.

A nozzle 16 is attached to the tip of the water supply pipe 14 that opens into the scattering chamber 9 (hereinafter, the water supply pipe that opens at the top of the straight pipe 5 is referred to as the water supply pipe 14, and the water supply pipe that opens to the scattering chamber 9 is referred to as the nozzle pipe 17. ).

Reference numeral 18 denotes a drain pipe, which is attached slightly above the lower end of the container 4 because a jet siphon device 19 is attached thereto.

When the jet siphon device 19 is not attached, the drain pipe is attached below the container 4 to allow the waste water to fall naturally.

20 is a controller for the motor 2.

The present invention has the above-mentioned configuration, but if the following parts are added to this, the invention becomes a further improved invention.

That is, a fixed shielding plate 21 is provided diagonally below the circumferential surface of the separator 6, and a negative pressure chamber 22 is provided between the separator 6 and the shielding plate 21.

This will improve water suction when separating the water adhering to the grains.

Further, if the straight pipe 5 is provided with a mesh, drainage of plow water becomes easy.

To explain the operation of the present invention, rice and other grains entering from the inlet 11 are transported upward within the straight pipe 5 by the spiral body 1, but during this time, they are supplied into the straight pipe 5 from the water supply pipe 14. Washed with water.

The washed grains are fed onto the separator 6 through the inlet 8.

Since the separator 6 is rotating, the grains are scattered in the scattering chamber 9 due to centrifugal separation, and the grains are scattered on the rotating rotary plate 10.
is guided to the outlet 12 and taken out from the outlet pipe 13.

On the other hand, the water adhering to the grains is detached from the grains by the centrifugal action of the separator 6 and falls downward into the container 4 through the mesh provided on the peripheral side of the separator 6.

At this time, by attaching a fixed shielding plate 21 and creating a negative pressure between the separator 6 and the separator 6, the rinsing water can be sucked in better, so that the rinsing water adhering to the grains can be removed more smoothly and quickly. It will be held in

The rinsing water that has fallen into the container 4 is drained from the drain pipe 18 by a jet siphon device 19.

After washing and taking out the grain in this way, nozzle pipe 1
The separator 6, rotary plate 10, straight pipe 5, and spiral body 1 are washed by jetting water from 7.

This is sufficient for normal cleaning after work, but the separation body 6,
Since the rotary plate 10, the straight pipe 5, and the spiral body 1 can each be disassembled, they can be disassembled and cleaned periodically.

As described above, according to the present invention, it is possible to automate the washing of rice and other grains, which has been troublesome in the past, and to perform complicated operations such as pouring water, rinsing, etc. all at once smoothly and quickly.

Additionally, if a shielding plate is attached and a negative pressure chamber is provided between the separators, the rinsing water adhering to the grains can be separated and dehydrated even more smoothly and quickly, making the cleaning process that much faster. It has the effect of becoming.
