Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a wet ice spraying device for removing rust from a ship hull. Background Art

[0002] In modern industrial production and daily maintenance, efficient and environmentally friendly cleaning technologies have attracted much attention. Wet ice cleaning technology has gradually come into people's view due to its unique advantages. It perfectly combines the cleaning ability of water with the low temperature characteristics of ice. Water can dissolve and flush pollutants, and the low temperature of ice can make pollutants brittle and easy to remove. Whether it is industrial equipment cleaning or daily facility maintenance, it can effectively remove various pollutants. Moreover, wet ice cleaning can reduce water waste. Compared with traditional high-pressure water cleaning, it requires less water. At the current time when water resources are tight, this advantage is outstanding, providing a feasible cleaning solution for sustainable development, and is expected to play a greater role in future industrial production and daily maintenance.

[0003] Chinese utility model patent announcement number: CN218226031U discloses a hull rust removal device, which starts a booster pump and extracts water from a water storage bucket filled with water through a pumping pipe. After being pressurized by the booster pump, the pressurized water is transported to the nozzle through the water pipe to spray out a high-pressure water flow. The impact force of the high-pressure water flow is used to break the adhesion of the original coating of the hull to the steel plate, thereby treating the rust. This method will not damage the steel plate, and is pollution-free and odorless, and has a good rust removal effect. For rusted surfaces at different positions, the movable support frame can drive the second roller, together with the water storage bucket and the nozzle, to facilitate rust removal operations. However, the hull rust removal device mainly relies on high-pressure water flow for rust removal, which consumes a large amount of water resources, and the grinding disc needs to be separated from the support frame for use, and the operation is relatively troublesome.

[0006] The crushing assembly includes a crushing tube, a placement trough, a top cover, a crushing roller, a driven wheel and a discharge tube. The upper end of the crushing tube is fixedly connected to the placement trough, the upper end of the placement trough is rotatably connected to the top cover, the crushing roller is rotatably connected inside the crushing tube, the right side of the crushing roller is fixedly connected to the driven wheel, and the lower end of the crushing tube is fixedly connected to the discharge tube;

[0007] The rotating component 1 includes a base, a shaft seat, a worm, a second motor and a worm wheel. The upper end of the base is fixedly connected to the shaft seat, the center of the shaft seat is rotatably connected to the worm, the rear end of the shaft seat is fixedly connected to the second motor, and the upper end of the base is rotatably connected to the worm wheel.

When in use, the top cover is opened, ice cubes are placed in the placement slot, and the motor is started to drive the driving wheel to rotate, and the driven wheel and the crushing roller are driven to rotate through the transmission belt. The crushing roller rotates to cut the ice cubes into fine ice particles for wet ice jet cleaning.

The crushing roller rotates to cut the ice cubes into small ice particles for wet ice blasting cleaning. A jet pump is set. When rust removal is performed, start the air compressor to inject high-pressure air into the jet pump. The jet pump mixes the ice particles with the high-pressure air, and discharges them from the jet pipe after passing through the outlet pipe. The cross-section of the tail end of the jet pipe is smaller than that of the head end. The ice particle and air mixture is accelerated through the jet pipe and ejected. The wet ice particles are sprayed under the high-pressure air. Driven by the air flow, the wet ice particles are sprayed onto the surface of the hull at a high speed. When the wet ice particles hit the rust, they continuously knock the rust and gradually break it up and remove it. The temperature of the wet ice is extremely low, which quickly reduces the temperature of the rust and the surrounding area, making the rust brittle and more easily destroyed by the impact of the wet ice particles. At the same time, the low temperature can also make some organic attachments on the surface of the hull, such as oil stains and paint residues, harder and more brittle, making them easier to remove together with the rust. In the process of sublimation from solid to gas, the volume of the wet ice will expand rapidly. The force generated by the expansion can further help remove the rust, resulting in good rust removal effect. The device is highly integrated and easy to use.

[0036] Example 2: Figure 2-6 As shown, it is an improvement to the previous embodiment.

[0037] Specifically, the lower end of the discharge pipe 1006 is fixedly connected to the upper inlet of the jet pump 13 , and the left side of the connecting pipe 12 is fixedly connected to the right inlet of the jet pump 13 . The advantage is that a jet pump 13 is provided. When removing rust, the air compressor 11 is started to inject high-pressure air into the jet pump 13. The jet pump 13 mixes the ice particles with the high-pressure air, and the mixture is discharged from the jet pipe 15 after passing through the air outlet pipe 14. The cross-section of the tail end of the jet pipe 15 is smaller than the cross-section of the head end. The ice particles and air mixture are accelerated and ejected after passing through the jet pipe 15. The wet ice particles are ejected onto the surface of the hull at a higher speed under the push of the high-pressure airflow. When the wet ice particles hit the rust, they continuously knock the rust to gradually break it and remove it. The temperature of the wet ice is extremely low, which quickly reduces the temperature of the rust and the surrounding area, making the rust fragile and more easily destroyed by the impact of the wet ice particles. At the same time, the low temperature can also make some organic attachments on the surface of the hull, such as oil stains, paint residues, etc., harder and more fragile, which is convenient for being removed together with the rust. In the process of sublimation from solid to gas, the volume of the wet ice will expand rapidly. The force generated by the expansion can further help remove the rust, and the rust removal effect is good.

[0038] Specifically, worm 1803 and worm wheel 1805 are meshedly connected, and the structures of rotating assembly 18 and rotating assembly 2 20 are identical.

[0041] Working principle: When in use, open the top cover 1003, put the ice cubes into the placement groove 1002, start the motor 17 to drive the driving wheel 8 to rotate, and drive the driven wheel 1005 and the crushing roller 1004 to rotate through the transmission belt 9. The crushing roller 1004 rotates to chop the ice cubes into fine ice particles. When derusting, start the air compressor 11 to inject high-pressure air into the jet pump 13. The jet pump 13 mixes the ice particles with the high-pressure air, and the mixture is discharged from the jet pipe 15 after passing through the air outlet pipe 14. When derusting the hull, the jet pipe 15 can be held for cleaning operations, or the jet pipe 15 can be fixed to the placement seat 21. Start the motor 2 1804 to drive the worm 1803 to rotate, and drive the worm gear 1805 to rotate. The up and down direction of the jet pipe 15 can be adjusted. The control rotation component 2 20 can adjust the left and right direction of the jet pipe 15. The worm 1803 and the worm gear 1 The driving mode of 805 has a self-locking feature, which facilitates stable rust removal and saves manpower. The cross-section of the tail end of the injection pipe 15 is smaller than that of the head end. The mixture of ice particles and air is accelerated and ejected through the injection pipe 15. The wet ice particles are pushed by the high-pressure airflow and sprayed onto the surface of the hull at a high speed. When the wet ice particles hit the rust, they continuously knock on the rust to gradually break it up and remove it. The temperature of the wet ice is extremely low, which quickly lowers the temperature of the rust and the surrounding area, making the rust fragile and more easily destroyed by the impact of the wet ice particles. At the same time, the low temperature can also make some organic attachments on the surface of the hull, such as oil stains, paint residues, etc., harder and more fragile, making them easier to be removed together with the rust. In the process of sublimation from solid to gas, the volume of wet ice will expand rapidly. The force generated by the expansion can further help remove the rust, and the rust removal effect is good.
