Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a leaf vegetable washing device that mainly washes leafy vegetables for pickling, such as mustard greens, Nozawa greens, Japanese greens, Chinese cabbage, Hiroshima greens, etc.

Generally, this type of leafy vegetable is washed in an aquarium by showering it with air bubbles.
The conventional washing device has a water tank 3 as shown in FIG.
A fumarole pipe 31 is disposed at the bottom of the water tank 30, a net conveyor 32 is suspended in the water tank 30, and nails 33 are protruded from the net conveyor 32 at a required interval. The leafy vegetables serving as the cleaning material W are suspended and moved within the water tank 30 while being washed by air bubbles from the fumarole pipe 31.

However, such conventional devices have drawbacks as listed below.

(1) It takes a lot of time and effort to lock it to a leafy nail and to remove it from the nail, and there is also a risk of getting your fingers injured by the nail.

(Leafy vegetables come off the nails in the aquarium, and not only does it take a lot of time and effort to pick them up, but the leafy vegetables that come off the nails prevent the other leafy vegetables from being transferred. They keep coming off the nails one after another, making cleaning work impossible.

(3) Using a net conveyor causes major damage to the equipment, making it very expensive, and not only is there a problem in terms of hygiene due to dust adhering to the net conveyor, but it also takes a lot of time to remove this trash. This requires a lot of time and effort, and maintenance and management of the device cannot be carried out easily.

(4) Air bubbles from the fumarole pipe are dispersed in the water tank and cannot be concentratedly applied to the leafy vegetables, so the air bubbles are wasted and the cleaning effect is poor.

As mentioned above, with conventional equipment, workability, equipment price,
It had many drawbacks in various respects, such as the handling of the device and the cleaning effect.

Therefore, in the present invention, a cylindrical body is hung horizontally in a water tank, and while leafy vegetables as objects to be washed are passed through the cylindrical body, air bubbles are intensively showered on the cylindrical body, thereby simplifying the work. By improving the cleaning effect and transferring the leafy vegetables within the cylinder using the flow of water caused by the force of air bubbles, the device can be simplified without the need for a separate drive device for transporting the leafy vegetables. The aim is to make it easier to configure and to keep the price low.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Reference numeral 1 denotes a washing cylinder which has an inlet 2 for the object W to be washed at one end and an outlet 3 at the other end, and is constituted by a cylindrical body having a circular cross section.

This washing cylinder 1 is horizontally suspended in a water tank 4, and in this case, the upper part of the washing cylinder 1 is exposed slightly above the water surface 4' of the water tank 4, and the washing cylinder 1 is placed inside the washing cylinder 1. A space 5 communicating with the outside air is provided.

In addition, 6°6 is a support rod installed upright on the top surface of the washing cylinder 1.
By forming a threaded portion σ at the tip and threading this through the angle material T installed on the top surface of the water tank 4, screw the nut 8 on, while adjusting the washing cylinder 1 to a horizontal state. I am trying to support it horizontally.

Further, 9 is a charging hopper connected to the charging port 2.

Further, in this embodiment, the cleaning cylinder 1 is constructed of a cylinder with a circular cross section, but it may be constructed as a cylinder with a square or polygonal cross section. The structure is not limited to a cylinder, but may be a single cylinder or multiple cylinders, and this may be appropriately selected in consideration of the throughput, installation location, etc.

10 is a fumarole pipe connected to the discharge side of the blower 11;
The nozzle pipes 1 are piped along the length directly below the washing cylinder 1, and the tips of a large number of nozzle pipes 12 are protruded from the upper surface of the washing cylinder 1 by penetrating the lower surface thereof.
The nozzle pipes 12 are opened at the distal end of the cleaning cylinder 1 in a longitudinally aligned manner, and the nozzle pipes 12 are connected to the exhaust port 3 of the cleaning cylinder 1. By inclining toward the side (approximately 60 degrees), the jet ports 13 are configured to be oriented obliquely toward the discharge port 3 side of the cleaning cylinder 1.

In this case, a through hole 14 having a larger diameter than the outer diameter of the nozzle pipe 12 is formed on the lower surface of the cleaning cylinder 1, and a gap 15 is maintained within the through hole 14 to allow the nozzle pipe 12 to be inserted therethrough. Accordingly, this gap 15 is used as a gap for discharging sand and the like.

Note that 16 is a stand for the blower, and 17 is an intake pipe connected to the suction side of the blower 11.

18 is a water supply pipe connected to a water pipe, and its water supply port 1
9 is opposed to the inlet 2 of the washing cylinder 1.

Reference numeral 20 denotes an overflow pipe, which allows water in the tank 4 to overflow from an overflow port 21 at the upper end, thereby maintaining the water level in the tank 4 at a constant level.

In the figure, 22 indicates a net, and 23 indicates a discharge pipe, and 24 indicates casters.

Therefore, inside the cleaning cylinder 1, air bubbles are generated by the air jetted from the jet nozzle 13, and since these air bubbles are jetted from the oblique jet nozzle 13 toward the discharge port 3 side, the cleaning The water in the cylinder 1 will flow from the inlet 2 to the outlet 3.

In this state, when a leafy vegetable as the object to be washed W is fed from the input port 2 with its stem end at the tip, the leafy vegetable is pushed through the washing cylinder 1 by the flow of water and is transferred to the discharge port 2.
As it moves, it is washed by air bubbles from below.

In this case, the leafy vegetables move by repeatedly rising and falling due to the floating action caused by being exposed to air bubbles from below and the sinking action due to their own weight, and the leaves are diffused by the air bubbles, and the diffused leaves are exposed to the air bubbles. Since the air bubbles are concentrated within the regulated area inside the washing cylinder 1, washing can be performed using the air bubbles effectively without letting the air bubbles escape.

At this time, if the inner diameter of the washing tube 1 is made to be just large enough to allow the expanded leaves of the leafy vegetables to pass through, all of the air bubbles can be bathed on the leafy vegetables without wasting them.

The leafy vegetables washed in the washing cylinder 1 as described above are discharged from the outlet 3, and then taken up to complete the washing work.

Incidentally, the garbage removed from the leafy vegetables during washing floats on the water surface and flows into the overflow pipe 20 from the overflow port 21 and is removed, and the settled matter such as sand falls from the gap 15. It will accumulate at the bottom of the water tank 4.

Furthermore, as shown in the embodiment, if the water supply port 19 is arranged to face the input port 2 in the washing cylinder 1, clean water is supplied into the washing cylinder 1, and the circulation of fresh water and dirty water is promoted. In addition, the flow of water in the washing tube 1 can be promoted, and the transfer of leafy vegetables can be made even smoother.

Further, in the embodiment, the object to be washed W is leafy vegetables, but it is also possible to wash other chopped vegetables and the like.

The present invention is configured as described above, and has various effects as listed below.

(4) Since the cleaning process is as simple as putting the items to be washed through the input port and picking them up from the discharge port, even women and women can do the work without any skill.
There is no danger.

(b) Since the objects to be washed are transferred by the flow of water within the washing cylinder, there is no need to provide a separate transfer device, and the device can be configured simply and the price can be significantly reduced. Maintenance and management becomes easier.

(c) Since a net conveyor, nails, etc. are not used, the objects to be washed are not damaged, and the work can be carried out smoothly without the transfer being delayed due to objects to be washed coming off the nails.

(→ Since the water in the tank is flowing, there is no dirt attached to it, making it sanitary.

(E) Since air bubbles can be concentrated on the object to be washed in the washing cylinder, the air bubbles can be used without wastage and mud and dirt firmly attached to the roots and stems can be completely removed. However, since the leaf portion can be washed in an expanded state, it is possible to completely wash even the septum, thereby significantly improving the cleaning effect.
