Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for grains such as rice, wheat, and other grains.

Conventionally, in this type of cleaning device, the bottom of the container is formed into a funnel shape, a communication hole is bored in the deepest part, the suction port of the circulation cleaning flow path faces near the communication hole, and the discharge port is placed above the container. In some cases, a granule discharge pipe is connected to the outlet of the circulation cleaning channel via a switching valve, and an aeration jet device is installed near the communication hole. It is relatively short and connected in a straight line on the outside of the container.
The granules collide and come into contact with each other, so there is little opportunity for cleaning action, and it takes a long time to clean the granules.Furthermore, the granules have to be circulated many times through the circulation cleaning channel and inside the container, and the aeration jet device is unable to clean them. This means that a large amount of washing water is required. Therefore, in the present invention, a circulating cleaning flow path is arranged in a spiral shape around the outer circumference of the container, with the aim of efficiently cleaning the granules quickly and using a small amount of cleaning water.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.

The container 1 is open at the top, has a funnel-shaped bottom 2, and has a communication hole 3 in the deepest part. The suction port 5 of the circulation cleaning channel 4 is located near the bottom of the communication hole 3 of the container 1 and communicates with it, and the outlet port 6 of the circulation cleaning channel 4 is connected to the communication hole 3 of the container 1.
Place it above. The discharge port 6 is provided with a granule discharge pipe 8 for guiding the washed granules out of the container 1 with a switching valve 7 for circulation and granule discharge operation interposed therebetween. The aeration jet device 9 includes an in-pipe nozzle 10 for introducing pressurized water or tap water, and an air introduction pipe 11 that is connected to and communicates with the injection side circumferential wall and opened near the in-pipe nozzle 10 to mix air into the jet water. Become. The injection direction of this aerated jet device 9 is the circulation cleaning channel 4.
It is attached to the lower end of the circulating cleaning flow path 4 with the suction port 5 of the filter facing. A drain pipe 12 is connected to the top of the side wall of the container 1 for discharging wastewater such as polishing liquid from the particles during circulation cleaning to the outside of the container 1.

The circulation cleaning channel 4 is arranged in a spiral shape around the outer circumference of the container 1, and in this embodiment, an example is shown in which it is provided within the thickness of the outer circumferential wall of the container 1. You can also place . Further, the diameter of the circulation cleaning channel 4 and the helical pitch are set depending on the granule cleaning conditions.

Next, the operation will be described.

First, grains such as rice are put into the container 1 from the upper opening. When the switching valve 7 is opened in the circulation direction (the state shown in the figure) and high-pressure water or tap water is introduced into the aeration jet device 9, air is introduced from the air intake pipe 11, and the aerated jet water ( A so-called mixed air jet is generated, an aerated water fountain is injected into the suction port 5 of the circulation cleaning channel 4, and the particles are sucked through the communication hole 3 of the container 1. The aerated jet water flows through the spiral circulation cleaning channel 4 together with the particles, enters the container 1 through the discharge port 6 and the switching valve 7, and flows into the circulation cleaning channel 4 through the suction port 5 again, where the fluid is circulated with the aerated jet water. While the particles flow together with the aerated jet water through the long spiral circulation cleaning channel 4, the particles collide and come into contact with each other to perform a sufficient cleaning action. The wastewater such as the polishing juice of the granules resulting from this washing flows out from the drain pipe 12 and is discharged. When cleaning of the granules is completed, when the switching valve 7 is switched to open to the granule discharge pipe 8, the granules are discharged from the granule discharge pipe 8 through the circulation cleaning channel 4, through the discharge port 9 and the switching valve 7. .

As described above, the present invention has the bottom surface of the container shaped like a funnel, a communication hole formed in the deepest part, the suction port of the circulation cleaning flow path facing the vicinity of the communication hole, and the discharge port located above the container. In a granule washer, the granule discharge pipe is connected to the outlet of the circulation cleaning channel via a switching valve, and an aeration jet device is installed near the communication hole. This is a granule washer that is arranged in a spiral shape in the container, and the circulation cleaning channel is arranged in a spiral shape around the outer periphery of the container, so the granules are washed in a spiral shape with aerated jet water for a long period of time. While flowing through the channel, the particles collide and come into contact with each other to perform a sufficient cleaning action, and the particles can be washed quickly and efficiently with a small amount of washing water. Also,
In the present invention, since the circulating cleaning flow device is disposed within the thickness of the outer circumferential wall of the container or on the outer surface of the outer circumferential wall, the washer can be made as compact as possible. Furthermore, as in the embodiment of the present invention, the structure of the granule washer can be extremely simplified since the granules can be washed simply by opening the container without providing any lid member or locking member on the upper part of the container. , can be provided at low cost, easy to maintain, and can be widely used in general households.
