Cavitating jet cleaning disc with recovery function

Abstract

The invention discloses a cavitating jet cleaning disc with a recovery function, which belongs to the technical field of cleaning. The cavitating jet cleaning disc with a recovery function comprises acleaning disc, a suction cover, a sewage pipe and a push handstand. The cavitation jet cleaning disc made by the scheme can be used for underwater cleaning of equipment such as ships or oil platforms. By adding the recovery system, microorganisms such as clams attached to the underwater part of a cleaned device and other contaminants can be effectively smashed and cleaned and can be recovered tothe shore for filtration to avoid secondary contamination on the seawater. In addition, the operation is convenient, the recovery efficiency is high, the cleaning efficiency of the underwater cavitating jet disc is not affected, and the anti-corrosion coating on the surface of the cleaned device is not damaged during the cleaning process.

Description

technical field [0001] The invention relates to a cavitation jet cleaning disc with recovery function, which belongs to the technical field of cleaning. Background technique [0002] At present, the cleaning of underwater parts such as ships or oil platforms usually uses rotary brush underwater cleaning equipment. The cleaning head is a rotating nylon brush or wire brush. The driving part is driven by a hydraulic motor and has a certain adsorption capacity. The advantages of this equipment It is simple to operate, safe and reliable, and has high cleaning efficiency. It is the most widely used underwater cleaning technology at present, but the rotary brush underwater cleaning technology also has many shortcomings: A. Destruction of the coating, due to the direct contact between the cleaning brush and the cleaning surface , when the material of the cleaning brush is improperly selected or the pressure is too high, the anti-fouling coating and anti-corrosion coating of the hull...

[0002] At present, the cleaning of underwater parts such as ships or oil platforms usually uses rotary brush underwater cleaning equipment. The cleaning head is a rotating nylon brush or wire brush. The driving part is driven by a hydraulic motor and has a certain adsorption capacity. The advantages of this equipment It is simple to operate, safe and reliable, and has high cleaning efficiency. It is the most widely used underwater cleaning technology at present, but the rotary brush underwater cleaning technology also has many shortcomings: A. Destruction of the coating, due to the direct contact between the cleaning brush and the cleaning surface , when the material of the cleaning brush is improperly selected or the pressure is too high, the anti-fouling coating and anti-corrosion coating of the hull will be damaged; B. The cleaning tools (brush head and scraper) need to be replaced frequently, which will increase the cleaning cost and reduce the cleaning speed ; C. The cleaning efficiency is not high for thicker hard marine organisms and aquatic plants; D. Cannot clean cylindrical surfaces and curved surfaces, such as ribs, light-shielding rudder plates, lattices, coupling rings, etc.; E. The use of hydraulic devices It may cause leakage of hydraulic oil, thereby polluting the environment; F. The tool end is huge and heavy, weighing more than a hundred kilograms, requiring hoisting equipment

[0003] Cavitation jet technology has relatively mature applications in many fields, such as material cutting, rock breaking drilling, oil well unblocking, ultra-fine crushing of materials, degradation of sewage in sewage, etc. Patent application 201110046757.0 applies cavitation jet technology In the field of underwater cleaning, a good cleaning effect has been achieved, but the garbage recovery after cleaning has not been realized. With the increasing requirements for environmental protection, it is necessary to develop a cavitation jet cleaning plate with recovery function to achieve a cleaner environment. Friendly underwater cleaning operations, thereby minimizing the impact on port water quality and marine ecology
