Description

Technical Field

[0001] The invention relates to the technical field of ship surface pretreatment, in particular to a surface cleaning pretreatment device for ship supercritical carbon dioxide spraying processing. Background Art

[0002] Supercritical carbon dioxide spraying for ships is an advanced ship surface treatment technology with obvious advantages. First, it can improve the atomization effect of the paint, allowing the paint to adhere better to the surface of the ship, making the coating more uniform and smooth. Secondly, due to the special properties of supercritical carbon dioxide, the paint can be sprayed at a lower viscosity, reducing the amount of paint used. Furthermore, it can also reduce the emission of volatile organic compounds (VOC), which is helpful for environmental protection.

[0003] Before supercritical carbon dioxide spraying of ships, in order to improve the spraying quality, it is often necessary to clean the surface of the ship. The common cleaning method is to first use a high-pressure water gun to perform low-pressure washing on the surface of the ship to remove surface stains, and then use a high-pressure water gun to perform high-pressure deep cleaning on the surface of the ship. Therefore, the surface of the ship needs to be cleaned twice, low pressure and high pressure. Not only does it take a long time, but the operation is also more laborious. After the surface of the ship is cleaned, there will be more water stains on its surface. These water stains attached to the surface of the ship are also prone to dust adhesion again, and are not easy to dry quickly, affecting the subsequent spraying time.

At this time, the high-pressure flushing area corresponds to the low-pressure flushing area, and the impurities on the ship can be heated and softened before low-pressure flushing, thereby effectively preventing dirty impurities from causing damage to the ship during the high-pressure cleaning process, and the softening of impurities is more conducive to deep cleaning operations.

[0029] Working principle: When cleaning, according to the cleaning position of the ship, the telescopic component 203 is rotated in advance, so that the telescopic component 203 is turned and adjusted through the steering plate 2012 and the rotating shaft 2017. After adjustment, the fixing bolt 2015 is rotated to make the fixing bolt 2015 penetrate into the fixing port 2013, and then the water source interface is connected to the joint 2065, and then water is delivered through the water source and sprayed through the nozzle 2063 to clean the ship; Then, the motor 2022 is controlled to drive the crank 2023 to rotate, and the crank 2023 drives the annular frame 2026 to reciprocate through the roller 2024, so that the annular frame 2026 drives the adjustment plate 2032 to reciprocate, and the adjustment plate 2032 drives the telescopic frame 2031 to reciprocate and retract, so that the telescopic frame 2031 drives the water outlet component 206, the steerable blowing component 205 and the hot blowing component 207 to reciprocate horizontally, so that the cleaning area of ​​the nozzle 2063 is increased, and the reciprocating extension and retraction of the telescopic frame 2031 can drive the shaft pin 2034 to move vertically, so that the shaft pin 2034 can drive the guide rod 2041 to move vertically. The tooth plate 2042 moves up and down, so that the tooth plate 2042 moves downward to mesh with the tooth valve 2064, so that the tooth valve 2064 increases the water output of the nozzle 2063, and the spray intensity of the nozzle 2063 is reduced. When the telescopic frame 2031 shrinks, the tooth plate 2042 moves upward, so that the tooth plate 2042 moves upward again to transmit to the tooth valve 2064, so that the tooth valve 2064 reduces the water output of the nozzle 2063, and then increases the spray intensity of the nozzle 2063. In this reciprocating manner, the telescopic frame 2031 is expanded to maintain the low-pressure cleaning of the nozzle 2063, and after the telescopic frame 2031 shrinks, the nozzle 2063 can be cleaned with high pressure; Secondly, during the reciprocating extension and retraction process of the telescopic frame 2031, the fan 2071 is made to take in air through the filter 2072 and exhaust air through the air duct 2073, so that part of the gas is discharged through the air outlet 2076, and the air flow is heated by the heating wire 2077, so that the hot air is discharged to the ship to soften the impurities. When it is necessary to adjust the vertical cleaning position of the ship, the cross telescopic arm 1025 can adjust the position of the mounting plate 1024, so as to adjust the vertical position of the adjustable cleaning pretreatment mechanism 200, so as to clean the vertical position of the ship, and the overall position can also be adjusted by the walking structure 101. At this time, the high-pressure cleaning area corresponds to the low-pressure cleaning area, so that the nozzle 2063 performs cleaning operations through high pressure again; When the fan 2071 is delivering air, another part of the air flow enters the circular cavity 2086 from the air hole 2078, so that the air flow passes through the connecting pipe 2052 and is discharged from the air outlet 2051. In addition, when the telescopic frame 2031 is unfolded, the rope 2084 is stretched to drive the rope drum 2083 to rotate, and the rope drum 2083 drives the circular cavity 2086 to rotate, and the circular cavity 2086 drives the torsion spring 2082 to twist. When the telescopic frame 2031 contracts, the torsion spring 2082 drives the circular cavity 2086 to rotate and reset, so that the circular cavity 2086 reciprocates, and the circular cavity 2086 drives the connecting pipe 2052 and the air outlet 2051 to rotate reciprocatingly, so that cold air drying operation can be performed in advance, and then a part of the air flow is heated by the heating wire 2077, and then high-temperature drying operation can be performed, so as to perform walking cleaning operation.
