Problems solved by technology

However, although the existing technology can increase the pressure of the water flow, due to the technical limitations of the water pump and the spray gun, the water pressure in the equipment cannot be increased blindly. The current cavitation jet technology has reached a bottleneck. How to further improve the effect of the cavitation jet, Improving the working efficiency and cleaning effect of underwater cleaning is a problem that is being researched and explored by those skilled in the art

Embodiment 1

[0054] see Figure 1 to Figure 7 As shown, the underwater cavitation jet cleaning system of this embodiment includes a support structure 1, a cleaning liquid automatic metering feeder 9 and a power unit 2 connected in sequence, a front pump 3, a filter 4, a plunger pump 5 and The high-pressure hose 6 and the power unit 2 provide power for the front pump 3 and the plunger pump 5 . The water outlet end of the high-pressure hose 6 can be connected with a cleaning gun 7 or a cleaning disc 8 as required.

[0055] The passage in the tube of the gun barrel 7-1 of the cleaning gun 7 is composed of a plurality of spherical chambers 7-2 in communication, and the diameter of the connecting portion of two adjacent spherical chambers 7-2 is smaller than the diameter of the spherical chamber 7-2, cleaning The nozzle 7-3 of the gun 7 gun barrel 7-1 is provided with a guide flow hole, and the guide flow hole includes an inflow channel 7-31 and a vortex section 7-32, wherein the vortex sectio...

Embodiment 2

[0067] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. In this example, the cleaning agent is composed of the following components: palm kernel oil fatty acid amidopropyl betaine 3.0%, coconut oil fatty acid diethanolamide 3.0%, glycyrrhetinic acid stearate 3.0%, lauryl glucoside 5.0%, N-dodecyl-β-alanine sodium 4.0%, N-acyl amino acid 3.5%, N-bishydroxyethyl dodecylamide 6.0%, dodecyl allyl succinate Sodium sulfonate 2.0%, sodium citrate 2.5%, maleic acid 2.0%, ethanol 12%, ethylene glycol 6.0%, and the balance is water. The preparation method of cleaning agent is different from Example 1 in that:

[0068] (1) With stirring at a speed of 700 rpm, heat the reaction kettle to 40°C and disperse for 8 minutes.

[0069] (2) Stir at 1200 rpm to fully dissolve.

[0070] (3) Rest for 2 hours in an ice-cold bath.

Embodiment 3

[0072] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The cleanser is composed of the following components: palm kernel oil fatty acid amidopropyl betaine 2.0%, coconut oil fatty acid diethanolamide 2.5%, glycyrrhetinic acid stearate 2.0%, lauryl glucoside 3.5%, N- Sodium lauryl-β-alanine 3.0%, N-acyl amino acid 2.0%, N-bishydroxyethyl dodecylamide 4.0%, sodium dodecyl allyl succinate sulfonate 1.8% , sodium citrate 1.7%, maleic acid 1.5%, ethanol 9%, ethylene glycol 4.6%, and the balance is water. The preparation method of cleaning agent is different from embodiment:

[0073] (1) With stirring at a speed of 550 rpm, heat the reaction kettle to 40°C and disperse for 6 minutes.

[0074] (2) Stir at a speed of 1000 rpm to fully dissolve.

[0075] (3) Stand still for 1.5 hours in an ice-cold bath.

[0076] Wherein, the cl...

Abstract

The invention provides an underwater cavitating jet cleaning system. The system is provided with a cleaning fluid autoweighing feeder, and a cavitating jet technology is organically combined with theimprovement on cleaning fluid so that jet bubbles can be increased, and hull dirty can be easily removed. A spiral channel is formed in the eddy section of a jet nozzle, and the eddy section is gradually decreased in the direction from a water inlet to a water outlet, so that the fluid velocity is further increased; the in-pipe cavities of a gun pipe are different in size, so that the fluid flowsthrough the inside of the pipe in a pulse mode, finally the fluid jetted from the jet nozzle of a cleaning gun is jetted in a pulse mode, the cavitation rate is effectively improved, and more cavitation nucleus are generated. A hollow rotation shaft of a cleaning disc is provided with a glow guide channel, a plurality of arc-shaped strips are arranged on the wall of the flow guide channel, the hollow rotation shaft jets the fluid downwards, and the fluid applies repulsion acting force on the cleaning disc, so that the cleaning disc is easily floated in water.

Description

technical field [0001] The invention relates to the technical field of underwater cleaning, in particular to an underwater cavitation jet cleaning system. Background technique [0002] After many years of sailing, a large ship will form a thick scale layer on the hull shell below the waterline, and at the same time, it will inevitably produce a large area of ​​corrosion. Therefore, when a large ship is overhauled, it is generally required to remove the old coating, scale and rust of the hull shell, and then apply new paint to ensure the normal navigation of the ship and prolong its service life. In recent years, with the development of pressurized water jet technology, this technology has been better used in the shipbuilding industry. The working principle of this technology is to use a high-pressure water pump to increase the pressure of ordinary water to 40-250MPa, and the flow rate of a single gun is about It is 20-39L / min, ejected from the nozzle to form ultra-high pres...
