Description

Technical Field

[0001] The invention relates to the technical field of wave condensers, and in particular to a cavitation wave condenser. Background Art

[0002] The cavitation wave condenser is an efficient cleaning device designed using the cavitation effect and the pressure wave focusing effect. Its core consists of a water inlet, a jet channel, a collision zone, and a water outlet. Through precise mechanical structure and fluid dynamics design, the water flow is cavitated, and the resonant cavity generates pressure waves. The pressure waves are reflected and focused through a specially designed structure to generate a high-pressure, high-temperature, and high-energy concentration zone. The cavitated bubbles grow fully in this zone, and the grown bubbles are quickly annihilated by the microorganisms through the water jet, thereby generating huge impact and shear forces, which can easily remove attachments such as barnacles on the bottom of the ship. The cavitation wave condenser can achieve efficient dirt removal and is suitable for cleaning guns, cleaning trays, cleaning robots, water flossers, fish tank cleaning, dishwashers, and cleaning of barnacles on the bottom of ships. Through the optimization design of adjustable delivery pipe size, guide vanes, turbulence enhancers, etc., the cavitation wave condenser can flexibly adapt to a variety of cleaning tasks, while improving cleaning efficiency and reducing energy consumption, and has a wide range of industrial and life application prospects.

[0003] Traditional cavitation ejectors are driven by high-pressure water flow. After entering the water inlet, the water is accelerated through a jet channel with a specific structure, forming a high-speed jet flow at the outlet. Through the optimized trumpet-shaped or tapered outlet, the water flow produces cavitation in the low-pressure area, forming a large number of tiny bubbles. These bubbles release high temperature, high pressure and strong impact force when they collide, compress and rupture, which are used to remove surface dirt or attachments. The equipment is widely used in cleaning guns, cleaning trays, cleaning barnacles on the bottom of ships and other scenarios. The water pressure and spray angle need to be manually adjusted according to the task requirements to optimize the cleaning effect.

[0004] Traditional cavitation ejector delivery pipes are usually of fixed size, and it is difficult to flexibly adjust the opening size according to actual needs, and thus it is difficult to meet the needs of different cleaning tasks, and it is difficult to adapt to different flow and pressure requirements, resulting in reduced efficiency.

[0005] In the cavitation wave focuser provided by the present invention, due to the wave focusing effect, high temperature, high pressure and huge energy are generated at the focusing point, so that the cavitation bubbles grow rapidly, and then go out through the jet. The cavitation bubbles are quickly annihilated when they encounter microorganisms, thereby generating huge impact force and shear force, so that attachments such as barnacles on the bottom of the ship can be easily removed. The cleaning effect of the cavitation wave focuser of the same size is at least twice that of the cavitation ejector, and the effective action distance of the former is more than five times that of the latter. Summary of the invention

[0006] In order to make up for the above shortcomings, the present invention provides a cavitation wave condenser, which aims to improve the problem that traditional cavitation wave condensers are difficult to meet the needs of different cleaning tasks, and thus difficult to adapt to different flow and pressure requirements, resulting in reduced efficiency.

In this area, bubbles grow fully, and the grown bubbles are quickly annihilated when they encounter microorganisms through the water jet, thereby generating huge impact force and shear force, and thus can easily remove attachments such as barnacles on the bottom of the ship.

[0012] Furthermore, both ends of the slide rod are slidably connected to the inside of the slide groove, and the slide groove is used to guide the movement of the slide rod.

[0013] Furthermore, the outer wall of the worm is rotatably connected to the inside of the regulating pipe, and the worm is used to drive the worm wheel to rotate.

[0014] Furthermore, the interior of the cavitation generator is arranged in an hourglass shape. When the water flows through the narrow part of the hourglass shape, the water flow velocity is significantly increased due to the reduction of the cross-sectional area, forming a high-speed jet.

[0015] Furthermore, the cavitation generating tube is arranged at one end of the resonance cavity to increase the focusing and rupture effects of the bubbles and enhance the impact force.
