Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has the following features: (1) It is possible to extremely easily clean pipes having a narrow cross-sectional opening, such as sewer pipes, or pipes connected in a non-linear manner, with an inexpensive structure; Conventionally, there are ultra-high-pressure washers that eject high-pressure water from an ultra-high-pressure pump from a washing nozzle and use the water energy to clean various equipment, such as on the surface of the equipment, inside the tank, etc. At the cleaning point Kf15, various cleaning nozzles can be appropriately selected and replaced. However, with the above-mentioned cleaning machine, #i It cannot be washed.

In view of the above-mentioned conventional drawbacks, the present invention makes the injection nozzle in the form of a bullet, communicates with a high-pressure water flow path for ejecting high-pressure water forward for cleaning, and branches the injection hole in the rear direction. The injection nozzle t is caused by the reaction force of high-pressure water jetting in
- It has a configuration that allows for
The injection nozzle was designed to allow the injection nozzle to penetrate into the deep part of the pipeline to easily clean it, and the high-pressure water was surrounded by high-pressure air and ejected to enhance the cleaning effect of the jet spray. It is a thing.

Next, the jet spray cleaning machine of the present invention will be explained in detail with reference to the drawings showing one embodiment thereof.

Structure of the present invention! , Fi, a flexible double vinyl pipe 3 consisting of an outer pipe 3a and an inner pipe sb to which high-pressure air and high-pressure water are supplied from an air compressor 1 and a high-pressure pump 2, respectively, is connected in communication with an injection nozzle 4 having a bullet-shaped outer shape. A high-pressure water flow path 6 that is connected to the inner pipe BhK runs through the injection nozzle 4 in its longitudinal direction, and a high-pressure air flow path 6 that is connected to the outer pipe 3a is provided around the high-pressure water flow path 6. is,
I! A high-pressure water injection hole 8 is formed which branches late from the high-pressure water flow path 6 and reaches the rear jetting lower, and a high-pressure air injection hole 9 that communicates and branches from the high-pressure air flow path 6 connects to the high-pressure water injection hole 8. The main idea is that it has a shape that is surrounded by a wall.

To explain in more detail, the air compressor 1 is connected to the outer tube connection portion 10a' of the double metal tube 10 consisting of the outer tube 10a and the inner tube 106d-1.

Moreover, the discharge pipe 11- of the high-pressure pump 2 is connected to the inner pipe connection part 106'.
This double metal pipe 10 is connected in communication with the .

It is communicatively connected to a double vinyl pipe 3 wound around a hose reel 12. On the other hand, to explain in detail the structure vX of the injection nozzle 4, the nozzle main body 13. &
The shape body 14 and the extension body 15 are connected with each other by screwing.
At the same time, from the deep inside the shape retaining body 14 and the extension body 16,
A shape-retaining body 14 has a diagonal plate 17 in which a plurality of through holes 16 are bored at regular intervals on the same circumference, and a plurality of water holes 18 are bored at regular intervals from the inner wall of the cylinder to the outer surface. A branch tube 20 has a plurality of spaced protrusions 19 formed on the outer circumferential surface thereof, and a plurality of spaced protrusions 21 are formed on the outer circumferential surface of the shape retaining body 14 and the extension body 15. A connecting cylinder 22 is fitted into and connected to the connecting cylinder 22, and each spaced protrusion 19°2
Shape retaining body 14 and extension body 1 formed using 1 as a spacer
A high-pressure air flow path is constituted by a dark space between each inner wall of 5 and each outer surface of branch tube 20 and connection tube 22. or,
The nozzle body 13 has inner grooves 23.
24 are respectively cut, and the circumferential grooves 23 and 24 are communicated with each other through a plurality of communication holes 26, thereby forming a part of the high-pressure air flow path 6. Similarly, in the shape retaining body 14, a concentric circle @28 with the high pressure water injection hole is drawn from the inner wall side and the outer surface side.
．． 27 are connected to each high-pressure water injection hole 8, respectively, and each of the circumferential grooves 2@, 21 communicates with each other through a communication hole 28. A high pressure air injection hole 41 is configured. In addition, a connecting tool connects the aoFi inner pipe 31 and outer pipe 32 in the figure to the tL Shiny vinyl pipe 3 and the injection nozzle 4.

38.34t;j each packing, 36ij double metal pipe 1
The air suction holes formed in the outer tube connection portion 10a' of No. 0 are shown respectively.

In the above-described embodiment of the jet cleaning machine, the heavy product peel pipe 30 is jetted from the high-pressure water passage 5 of the jet nozzle 4 through the inner pipes 106 and 3M, and the high-pressure air from the air compressor 1 is , the jet is injected from the inner groove 23 through the outer pipes IQg, 8a of the double metal pipe 10 and the double vinyl pipe 3, and the high pressure air flow path 6t of the injection nozzle 4. Therefore, the jet high pressure water is dependent on the high pressure air. Because it is surrounded, there is extremely little loss of water flow energy of high-pressure water, allowing for efficient spray cleaning. On the other hand, in the injection nozzle 4, a branch pipe 2 is branched from the high pressure air flow path 5.
The high-pressure water that has passed through the water passage hole 18 of 0 and each high-pressure water injection hole of the shape retaining body 14 is ejected backward from the ejection lower, and
The ejected high-pressure water is also surrounded by the high-pressure air ejected from the internal structure 27 in the same manner as described above, thereby preventing loss of water flow energy, and the reaction force of this efficiently ejected high-pressure water appetizer is used to form an injection nozzle. A driving force is generated towards the leader. Therefore, narrow
If a blockage occurs in the deep part of a pipe that is 4° wide or a non-linear pipe, when the injection nozzle 4 is inserted into the pipe, the hose reel 12 rotates and is wound around the skeleton hose 12. Since the double vinyl pipe 3 is extended and the injection nozzle 4 enters the pipe, it can be easily cleaned. If the pipe is turned down, for example, even if the pipe is bent at a right angle, since the outer shape of the injection nozzle 4 is bullet-shaped, the injection nozzle 4 will enter the pipe without coming into contact with a corner and stopping.

As described above, the jet cleaning machine of the present invention, despite its simple and inexpensive configuration, can extremely easily clean knots and dirt inside the pipes, which were difficult to clean in the past. By enclosing high-pressure water with an air curtain, it exhibits powerful cleaning power and produces unprecedented effects.
