Description

The present invention relates to cleaning and peeling of an object, burdock, radish, carrot and the like passing through a hollow cylinder.

In terms of equipment, burdock, radish, carrots, etc. are placed on buckets and conveyors, and high pressure water is used, and a direct injection nozzle is swung or reciprocated to inject high pressure water for cleaning and peeling.

In the above method, cleaning, peeling, etc. cannot be completely cleaned and peeled in one spraying process, and the actual condition is that the spraying position is changed or the direction is changed several times. As a result, a large amount of water and energy are consumed.

The object of the present invention is to clean the surface of a cylindrical or polygonal rod-shaped object by passing through the inside of the unit once, and the root vegetables such as burdock and carrot are cleaned and peeled once. The purpose is to provide a high-pressure nozzle swiveling unit that can be completed by passing through and can save water and energy.

In order to achieve the above object, the present invention is directed to the axial direction toward the central direction of rotation of the ring via the nozzle mounting block on the end surface near the outer periphery of the ring-shaped disk that rotates the high-pressure nozzle. Is a unit in which a high-pressure nozzle is swiveling at an angle, tilting, mounting a plurality, and injecting high-pressure water.

If the high-pressure nozzle swivel unit of the present invention is used for a high-pressure washing machine or the like, the high-pressure nozzle itself turns and passes an object in the turning axis direction at the turning center position where the swirling jets injected from the tip of the plurality of nozzles intersect. If this is done, a high-pressure jet will hit the entire surface of the object, and it can be expected to be used in many fields. In the field of vegetable industry, cleaning and peeling of root vegetables such as burdock, carrot and radish can relieve the labor of the currently used nozzle swinging type or manual labor, water resources and energy saving. I can expect.

In Fig. 1, the side with the hollow cylindrical body 3A with the rotating ring 7A and high-pressure nozzle 9A is defined as the outlet side, and the opposite side is defined as the inlet side. The high-pressure water is supplied from the two water supply ports 4A at the high-pressure water inlet of the hollow cylindrical body 3A, passes through the hole in the cylindrical body 3A, passes through the hole formed in the bearing 11A, and the groove of the link disk rotating ring 7A. From the groove, the nozzle block 7A is distributed to each high-pressure nozzle 9A. By providing the groove, high-pressure water can be stably sent to the high-pressure nozzle 9A even when the rotary ring 7A is rotated at a high speed.

Jets jetted from the swiveling high-pressure nozzles 9A are directed to the center of swirling and collide at a certain position. From the entrance side, the hollow cylindrical body 3A has a cylindrical shape such as burdock. If you send the object, you will enter the swirling jet. If the injection angle of the high pressure nozzle 9A is made perpendicular (0 degree) to the swivel axis, the cylindrical object stays at that position and continues to receive the jet at the same place, and the injection angle of the high pressure nozzle is If a swirling jet with an angle of 15 or 30 degrees in the direction of the exit side is applied to an object, a component force is generated by the jet in the direction of the exit of the swivel axis. Since the nozzle moves in the direction of the outlet, the nozzle mounting angle is an important factor for the high-pressure nozzle swivel type.

In the high-pressure nozzle swivel type, the jet flow injected into the atmospheric pressure from the swiveling high-pressure nozzle 9A has a high pressure in the nozzle and a slow flow rate because pressure energy is converted into velocity energy at once. Since the impact energy of the jet changes depending on the distance from the exit end face of the high pressure nozzle 9A to the object, the maximum effect can be expected by mounting the nozzle at an appropriate distance (between 20 mm and 400 mm) from the object.

A chain is used for the sprocket wheel 5A attached to the rotating ring 7A via a support 6A, and the rotating ring 7A is rotated by an external driving device to rotate the high pressure nozzle 9A.

For measures against high-pressure water leakage at the rotating ring 7A and the bearing 11A, packing, rubber seals, etc. are not used. However, since the water flow ejected from a small gap is dangerous, a ring-shaped groove is formed on the side surface of the bearing 11A in FIG. 3, and a plurality of holes are formed from the bottom surface of the groove to the mounting surface of the bearing 11A. Make a hole through the flange. A similar method is used for the holding plate 10A, in which high-pressure leaked water is slowly discharged from the hole.

By examining the amount of water leaking from the above holes, it is possible to know the degree of wear of bearings. The material of the bearing 11A and the holding plate 10A is gunmetal or Teflon. The other component is SUS304 or SUS316.

It is sectional drawing of the side surface of this invention. It is a front view. It is a front view of a bearing.

Claims (4)

The hollow cylindrical body has a ring-shaped disk that rotates, and is attached to the end surface of the rotating ring. The high-pressure nozzle swivel unit is characterized by jetting high-pressure water (liquid) while rotating and passing a cylindrical or polygonal rod-shaped object into the hollow of the hollow cylindrical body. In order to supply high-pressure water (liquid) to the nozzle block on the average, a method is provided in which grooves are formed on the inner surface of the rotary ring inner diameter in contact with the bearing and the high-pressure water is supplied to each nozzle block via the grooves. The high-pressure nozzle mounting angle with respect to the rotation axis direction of the rotary ring is 0 degree perpendicular to the rotation axis direction, 5 degrees on the hollow cylindrical body side, and 60 degrees on the opposite swivel nozzle side. Nozzle mounting angle. The high-pressure nozzle attachment distance position is a distance from the surface of the object passing through the center of the ring rotation axis to the end face of the high-pressure nozzle that is 20 mm or more and 400 mm or less.
