[0011]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 and FIG. 2 show an example of an apparatus for cleaning, cutting and stripping using ultra-high pressure water according to the present invention. This apparatus basically produces ultra-high pressure water of about 2000 atm. It is composed of a pump 1, a nozzle 2 for injecting ultra-high pressure water from the pump 1, and a pedestal 3 for supporting each component including a unit related to them.

As shown in the figure, the pedestal 3 is usually formed in a rectangular parallelepiped shape, and is preferably made of aluminum alloy or carbon fiber for weight reduction. Four casters 4 are preferably provided on the lower side of the lower frame 3a in a well-balanced manner to make the working machine movable. Further, the pedestal 3 is appropriately configured so that each unit such as the pump 1 can be easily attached and detached.

This working machine is mainly characterized in that the pump 1 is driven by pressurized air, and therefore, the upper frame 3 of the pedestal 3 is used.
In b, a pressurized air supply port 5, an air shutoff valve 6, an air filter 7 as an oil / water separator, an oiler 8, a pressure adjusting valve 9, and an air pressure gauge 10 are installed. As a water system, a water supply port 11, a water shutoff valve 12, a water prefilter 1
3, a water pressure gauge 14, a water filter 15, and an ultrahigh pressure water pressure gauge 16 are installed. Reference numeral 17 is a bypass outlet.

Another feature of the working machine using the ultra-high pressure water is that each constituent unit is compactly arranged on the lightweight mount 3, and each constituent unit or at least some of them for facilitating disassembly and assembly. Is attached by a suitable type of clamping member, and examples of the clamping member include a double angle plate, a side clamp, a block system such as a swing clamp, a fixed spanner, and an air clamping modulus. Clamping system, as well as brackets, shaft holders, one-touch fittings, quick-fastening nuts and other fittings are selectively used.

The upper frame 3b of the frame 3 is a clamper 18
It is detachably attached to the gantry body, which makes it possible to divide the gantry 3 into two parts, thus making it easier to disassemble the working machine and clamping one unit to each gantry part if desired. There is an advantage that it can be fixed by a means other than the member, and the handling becomes easier. Preferably, the pump 1 is installed on the lower frame 3a.

FIG. 3 shows an operation system of this embodiment. When using, when a pressurized air pipe provided at the site is connected to the pressurized air supply port 5, the pressurized air is supplied to the valve 6 When it is opened, it is introduced from the supply port 5, foreign matter in the air is removed by the air filter 7, oil and fat are added by the oiler 8, and the operation of the diaphragm of the pump 1 is made smooth. Next, the air serving as the power source is set to 5 kg / square cm by the pressure adjusting valve 9.

On the other hand, the feed water is introduced from the feed port 11 by opening the valve 3, foreign matters are removed by the water pre-filter 13 and the water filter 15, and the feed water is introduced into the ultra-high pressure water generation pump 1. This pump 1 is usually a double-diaphragm piston type pump, which uses, for example, 5 kg / square cmG, 4N cubic m / min of pressurized air as power, and 2000 kg of 1.5 liter / min of water.
It is possible to pressurize to an ultrahigh pressure of / cm 2. By introducing this ultra-high pressure water into the ultra-high pressure water jet gun 2, cleaning or cutting or peeling with the ultra-high pressure water can be performed.

In this apparatus, each constituent unit, in particular, the ultra-high pressure pump 1, the injection gun 2, the filters 9, 13, 15 and the like are selected in an optimum combination to achieve high performance, compactness, and weight reduction. If desired, an abrasive jet nozzle may be used as the injection nozzle 2 so that it can be more suitably used as a working machine for cutting. In this case, an intensifier is installed in the middle of the pressure-resistant hose in order to further increase the injection pressure from the nozzle. It is also possible, or if desired, a booster pump, polymer mixer or the like may be inserted. Also in this case, like the above-mentioned one, disassembly and assembly are easy, and it can be used as a portable one.

The device according to the invention thus uses pressurized air as the power source and does not use an electric motor, so that it is significantly lighter in construction. When an electric motor is used as a power source as in the conventional case, an electric motor of 10 horsepower is required to obtain a pressure of 2000 kg / square cm, and an ultrahigh-pressure water generator with a total weight of 215 kg is used. Weight about 83k
g, ultra-high pressure water with an injection pressure of 2000 kg / square cm and a water injection amount of 1.5 liters / min is obtained, similar to the case of using an electric motor as a power source. The same performance as when using a power source is obtained.

In this way, the working capacity of the ultra-high pressure water can be exerted, and the main unit centering on the pump 1 is attached to the lightweight pedestal 3 by the clamping member, so that the device can be easily disassembled and assembled. Therefore, this device can be easily transported to the use position. Further, the gantry 3 is composed of an upper frame 3b and a lower frame 3a and is configured to be easily bisected, the pump 1 is installed in the lower frame 3a, and other main units are installed in the upper frame 3b. This makes it possible to divide the entire apparatus together with the gantry more easily and with appropriate balance, and to move the apparatus to the use position more easily.

[0021]

As described above, according to the present invention, the device for generating and utilizing the ultra-high pressure water has a light weight structure, and therefore can be moved like a portable tool. Therefore, even if the floor or wall of the facility cannot be moved or is difficult, the cleaning, cutting, and peeling work can be easily performed with the ultra-high pressure water.

Further, by optimally selecting the constituent units, it is possible to save resources, for example, a pressure of 2000 kg / square cm.
The water consumption can be about 1.5 liters / minute, and the water jet can be intensively ejected to reduce the splash of water and the pollution of noise and vibration.
In addition, a lightweight gantry is composed of an upper frame and a lower frame so that it can be easily divided into two parts, and a pump is installed in the lower frame. By proper arrangement, this device can be divided into two parts in good balance. Therefore, the transportation of this device becomes easier.
