Description

Technical Field

[0001] The invention relates to the technical field of ship cleaning, in particular to an ultrasonic rust removal and paint spraying integrated device. Background Art

[0002] The ship deck is an important part of the ship structure, and its performance and safety are crucial to the normal operation of the ship. However, the ship deck is prone to rust. This is because the ship is exposed to the marine environment for a long time, and is corroded by salt, moisture and oxygen, which causes corrosion of steel materials, thereby affecting the performance and safety of the ship. At present, rust removal technologies mainly include mechanical rust removal, chemical rust removal and electrochemical rust removal. Among them, mechanical rust removal methods will cause greater stress and damage to steel materials, chemical rust removal methods will produce harmful waste and environmental pollution, and electrochemical rust removal methods are unstable and difficult to operate. In contrast, ultrasonic rust removal technology can effectively remove rust and dirt on the surface of the ship deck through the vibration and impact of ultrasonic waves without the use of chemical agents, and does not damage the materials and structures of the ship deck. It is expected to become one of the mainstream technologies for ship rust removal in the future.

[0003] However, ultrasonic rust removal technology must rely on cleaning fluid to achieve the purpose of cleaning and rust removal. Leakage of cleaning fluid during the cleaning process will lead to a decrease in rust removal efficiency. At the same time, if the cleaning fluid cannot be effectively treated and recycled, it may pollute the environment. These problems have hindered the development of ultrasonic rust removal technology. Summary of the invention

[0004] In view of the technical problem that the cleaning liquid is easy to leak and pollute the environment, the present invention provides an integrated ultrasonic rust removal and painting device, which uses a pneumatic rod to press the cleaning cabin onto the deck surface to prevent leakage, removes rust from the rusted parts through the ultrasonic transmitter in the cleaning cabin, and then recovers the waste liquid and waste residue in the cleaning cabin through the waste liquid recovery tank to avoid environmental pollution. The treated deck surface is sprayed with paint by the rear spraying device, realizing the integrated design of rust removal and painting to avoid secondary rust.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto. Example 1

[0025] The ultrasonic rust removal and paint spraying integrated device described in this embodiment includes a housing 1, a travel wheel 2 supported at the bottom of the housing 1, a first motor 3 arranged in the housing 1, an ultrasonic rust removal device, a paint spraying device and a PLC control system 4. Figure 1 This is a schematic diagram of the structure of the integrated ultrasonic rust removal and paint spraying device described in this embodiment.

[0026] The first motor 3 is used to drive the driving wheel 2 to move on the deck. The ultrasonic rust removal device includes a base 5 fixed in the housing 1, a plurality of pneumatic rods 6 installed below the base 5, a cleaning cabin 7 fixed on the pneumatic rods 6, and a second motor 8 used to drive the pneumatic rods 6 to press the cleaning cabin 7 onto / off the deck surface. A sealing ring 20 for improving the sealing effect between the cleaning cabin 7 and the deck and a pressure sensor for detecting the pressure value between the cleaning cabin 7 and the deck are provided at the bottom of the cleaning cabin 7. The pressure sensor is connected to the PLC control system 4, and the indication of the pressure sensor is used to ensure whether the cleaning cabin 7 and the ship wall are sealed. A pipeline on one side of the cleaning cabin 7 is connected to a cleaning liquid storage tank 9, and a pipeline on the other side is connected to a waste liquid recovery tank 10. Both pipelines are made of rubber, and a first water pump 11 and a second water pump 12 are respectively provided in the pipelines. A thermostat 19 is provided in the cleaning liquid storage tank 9, which is used to maintain the cleaning liquid temperature in the cleaning liquid storage tank 9 at about 60°C, so as to accelerate the chemical reaction of the cleaning liquid in the cleaning cabin 7, so that the rust is more easily decomposed and dissolved, thereby improving the rust removal effect. An ultrasonic transmitter 13 for rust removal is arranged in the cleaning chamber 7 .

[0027] The paint spraying device comprises a paint tank 14, a nozzle 15 and an air pump 16 connected to the paint tank 14 and the nozzle 15, which are arranged behind the ultrasonic rust removal device. A first drying machine 17 is arranged between the ultrasonic rust removal device and the paint spraying device, and a second drying machine 18 is arranged behind the paint spraying device.

[0028] The PLC control system 4 is electrically connected to the control units of the first motor 3, the second motor 8, the first water pump 11, the second water pump 12, the air pump 16, the first dryer 17, the second dryer 18 and the ultrasonic transmitter 13. The PLC control system 4 can be used to realize operational control of the first motor 3, the second motor 8, the first water pump 11, the second water pump 12, the air pump 16, the first dryer 17, the second dryer 18 and the ultrasonic transmitter 13.

[0029] Furthermore, a vent 21 is provided on the top of the shell 1 for discharging the hot and humid gas out of the shell 1 .

[0030] The specific implementation of the ultrasonic rust removal and paint spraying integrated device described in this embodiment is as follows:

[0031] The PLC control system 4 is used to control the second motor 8 to push the pneumatic rod 6 downward, gradually pressing the cleaning chamber 7 to the deck surface. During this period, the indication of the pressure sensor is observed. When the indication reaches the set value, the cleaning chamber 7 and the deck have been sealed, and the pressure sensor is stopped from being pushed. The PLC control system 4 is used to control the first water pump 11 to inject cleaning liquid into the cleaning chamber 7. At this time, the air in the cleaning chamber 7 is compressed, so that the cleaning chamber 7 is in a high-pressure state. When the liquid level reaches 50 mm, the first water pump 11 is turned off, and the ultrasonic transmitter 13 is turned on. The cavitation effect of ultrasonic waves in the cleaning liquid is used to remove rust. The high-pressure environment can increase the energy transmission and penetration ability of ultrasonic waves, thereby improving the rust removal effect. After the end, the PLC control system 4 is used to control the second water pump 12 to drain the cleaning liquid in the cleaning chamber 7, and then the PLC control system 4 is used to control the retraction of the pneumatic rod 6, control the first motor 3 to drive the driving wheel 2, and turn on the first dryer 17 to dry the deck surface after rust removal. When the rusted part is located below the nozzle 15, the PLC control system 4 controls the air pump 16 to spray the paint from the nozzle 15 to the rusted part, and the second dryer 18 is turned on to dry the deck surface after painting. Then the travel wheel 2 is driven to the next rust removal area. Example 2

[0032] The difference between this embodiment and the first embodiment is that a plurality of vents are provided on the top of the cleaning chamber 7. The other structures are the same as those of the first embodiment. The vents can reduce the air pressure in the cleaning chamber 7, thus preventing the sealing ring 20 from leaking due to excessive air pressure.

[0033] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
