They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] like Figures 1 to 5 As shown, the present invention provides a cultural relic desalination device, which comprises: The outer cylinder 1 has an open top and a water outlet 12 at the bottom, and a water inlet 11 is provided at an upper portion of one side of the outer cylinder 1; The inner cylinder 2 is coaxially rotatably disposed in the outer cylinder 1, the inner cylinder 2 has an open top, and a plurality of mesh holes are disposed on the circumferential side surface and the bottom surface; A cover plate 3 is slidably disposed in the inner cylinder 2 along the axial direction of the inner cylinder 2; A plurality of first air bags 41 are arranged on the inner cylinder 2 at intervals along the circumferential direction; At least one second air bag 42, which is arranged on the inner wall of the bottom surface of the inner cylinder 2; At least one third airbag 43 is disposed on the inner side of the cover plate 3 ; the cultural relics to be desalted are located in a space surrounded by the first airbags 41 , the second airbags 42 and the third airbags 43 .

[0022] The above technical solution provides a cultural relic desalination device, which is particularly suitable for performing effective and safe desalination operations on cultural relics that contain excessive salt and require desalination treatment.

[0023] Specific description of each component of this technical solution: Outer cylinder 1: The outer cylinder 1 is the main structure of the whole device, which is designed to be open at the top. A water inlet 11 is provided on the upper part of one side of the outer cylinder 1 for injecting desalted water or other desalting solutions into the device. A water outlet 12 is provided at the bottom of the outer cylinder 1 for discharging the brine or other solutions generated during the desalination process. During a desalination operation, the solution inside the outer cylinder 1 can be replaced multiple times to ensure the desalination effect.

[0024] Inner cylinder 2: The inner cylinder 2 is coaxially rotatably arranged in the outer cylinder 1, and its top is also open, which is convenient for putting in and taking out cultural relics. There are multiple mesh holes on the circumferential side and bottom of the inner cylinder 2, which allow the desalination solution to freely penetrate into the inner cylinder 2. The cultural relics to be desalinated are placed in the inner cylinder 2. During the desalination process, the inner cylinder 2 is rotated relative to the outer cylinder 1, thereby driving the cultural relics to rotate, so that the cultural relics rotate in the solution during the desalination process, thereby improving the desalination efficiency of the cultural relics.

[0025] Cover plate 3: The cover plate 3 is slidably arranged along the axial direction of the inner cylinder 2. It can move up and down in the inner cylinder 2 and can be suitable for cultural relics of different heights. The cover plate 3 and the bottom surface and circumferential side surface of the inner cylinder 2 form a space for accommodating cultural relics. The cover plate 3 is provided to provide a more stable and safe desalination environment for the cultural relics.

[0026] First airbag 41: In the circumferential direction of the inner cylinder 2, a plurality of first airbags 41 are arranged at intervals along its inner wall. After being inflated, the plurality of first airbags 41 can cling to the periphery of the cultural relics, thereby effectively fixing the cultural relics and preventing the cultural relics from being drastically moved or rolled over due to the rotation of the inner cylinder 2 during the desalination process, resulting in frequent collisions between the cultural relics and the inner wall of the inner cylinder 2 and causing damage to the cultural relics. At the same time, the softness of the airbags can also provide a certain degree of protection for the cultural relics.

[0027] Second airbag 42: At least one second airbag 42 is arranged on the inner wall of the bottom surface of the inner cylinder 2. After the second airbag 42 is inflated, it can lift the bottom of the cultural relic upward to ensure that the cultural relic maintains a certain distance from the bottom surface of the inner cylinder 2, thereby avoiding direct contact between the cultural relic and the bottom surface and possible damage caused by friction.

[0028] Third airbag 43: At least one third airbag 43 is disposed on the inner side of the cover plate 3. When the cover plate 3 slides down and clings to the cultural relic, the third airbag 43 can further fix the top of the cultural relic and further provide additional support and protection.

[0029] During the desalination process, the desalination solution can penetrate around the cultural relics through the mesh holes on the inner cylinder 2, react with the salt in the cultural relics and take them away. As the desalination process proceeds, the solution containing salt can be regularly discharged through the water outlet 12 of the outer cylinder 1, and new desalination solution can be added to maintain the desalination effect.

[0030] According to the size of the cultural relics to be desalted, the cover plate 3 is adjusted to slide axially along the inner cylinder 2, and the inflation amount inside the first airbag 41, the second airbag 42 and the third airbag 43 is controlled, so that the periphery of the cultural relics to be desalted is in close contact with the first airbags 41, the bottom is in close contact with the second airbag 42, and the top is in close contact with the third airbag 43.

[0031] How to use When using the cultural relic desalination device of the present invention, firstly, the cultural relic to be desalted is placed in the inner cylinder 2, and the cover plate 3 is placed in the inner cylinder 2, and then the first airbag 41, the second airbag 42 and the third airbag 43 are inflated, so that the first airbag 41, the second airbag 42 and the third airbag 43 support the cultural relic, and an appropriate amount of desalination solution is injected into the device through the water inlet 11 of the outer cylinder 1, and the liquid level of the desalination solution in the device is at least higher than the top of the cultural relic. After the desalination solution is injected, the driving mechanism is started to drive the inner cylinder 2 to rotate relative to the outer cylinder 1, and the desalination efficiency of the cultural relic is improved while rotating during desalination and soaking; after a period of time, the desalination solution in the device is completely discharged through the water outlet 12, and then fresh desalination solution is introduced into the device again through the water inlet 11, and desalination is performed again. The desalination solution can be replaced multiple times until the salt concentration of the desalination solution discharged from the water outlet 12 is lower than the preset threshold value, and then the desalination is completed, and the solution inside the device is completely discharged through the drain port, and the inner cylinder 2 is continuously rotated to dry the cultural relic.

[0032] When the desalination process is completed, the first, second and third air bags 43 can be restored to their original state by degassing, and the gas inside the first, second and third air bags 43 can be slowly released, so that the desalinated cultural relics slowly tilt and lean against the inner wall of the inner cylinder 2, and then the cover plate 3 is taken out from the inner cylinder 2, and then the desalinated cultural relics can be taken out for subsequent processing or preservation.

The sealing ring 71 is provided at the end of the slider 31. When inflated, the gas enters the sealing ring 71 through the fourth air duct 72, and the sealing ring 71 is propped up to block the gap between the end of the slider 31 and the tube wall of the second air duct 45, thereby ensuring the air tightness between the slider 31 and the air port 46 of the second air duct 45, reducing gas leakage, and avoiding the end of the slider 31 and the second air duct 45 (air port 46) being too close to each other, and the excessive friction between them affects the smoothness of the lowering of the cover plate 3, and may also wear the tube wall of the second air duct 45.

[0043] In another technical solution, in the cultural relic desalination device, multiple protrusions are arranged at intervals on the outer surfaces of the first airbag 41, the second airbag 42 and the third airbag 43. The multiple protrusions are arranged to increase the friction between the airbag and the outside of the cultural relic, and to avoid unnecessary shaking of the cultural relic relative to the airbag during the rotation. At the same time, the protrusions are arranged so that the airbag forms multiple point contacts with the outside of the cultural relic instead of surface contacts, so that the desalination solution can penetrate between the airbag and the cultural relic, thereby increasing the contact area between the desalination solution and the cultural relic, and thus improving the desalination efficiency.

[0044] In another technical solution, the cultural relic desalination device further includes a motor 22, which is arranged at the bottom of the outer cylinder 1, and the output shaft of the motor 22 is coaxially arranged with the inner cylinder 2 and connected to the bottom of the inner cylinder 2. The motor 22 is set as a driving mechanism for the rotation of the inner cylinder 2. Preferably, the motor 22 can be set as a reciprocating forward and reverse servo motor 22, which can drive the inner cylinder 2 to reciprocate forward and reverse, further improving the desalination efficiency. The motor output shaft rotates in a sealed manner through the bottom surface of the outer cylinder and continues to extend upward and connects to the bottom surface of the inner cylinder.

[0045] In another technical solution, in the cultural relic desalination device, an ultrasonic oscillator is provided on the outer cylinder 1. The ultrasonic oscillator is provided on the inner wall of the outer cylinder 1 to further improve the desalination efficiency of the cultural relic. The ultrasonic oscillator is used to emit ultrasonic waves to the cultural relic to be desalted during the desalination process to promote the separation of salt from the cultural relic and accelerate the desalination process. When ultrasonic waves propagate in a liquid, a strong cavitation effect will be generated. That is, the tiny bubbles in the liquid are rapidly generated and broken under the action of ultrasonic waves, generating powerful shock waves and microjets. These shock waves and microjets can penetrate the tiny gaps on the surface of the cultural relic to separate the salt from the cultural relic. The cavitation effect of the sound wave can not only promote the separation of salt, but also accelerate the contact and mixing of the desalination solution with the surface of the cultural relic. At the same time, the vibration of the ultrasonic wave can also make the tiny particles or bubbles in the desalination solution disperse evenly, further improving the desalination efficiency. The ultrasonic desalination process does not cause mechanical wear or chemical corrosion to the cultural relic itself, so it is a safe and effective desalination method. The application of the ultrasonic oscillator can significantly improve the desalination efficiency and quality.

[0046] It can penetrate into the tiny gaps on the surface of cultural relics and completely separate the salt without causing any damage to the cultural relics. The ultrasonic oscillator is an existing device, for example, the ultrasonic oscillator includes an ultrasonic generator arranged on the outer wall of the outer cylinder 1, an ultrasonic vibration plate arranged on the inner wall of the outer cylinder 1, and a transducer connecting the ultrasonic generator and the ultrasonic vibration plate. The transducer is used to convert the high-frequency electrical signal generated by the ultrasonic generator into mechanical vibration, and transmit the mechanical vibration to the desalination solution in the device through the ultrasonic vibration plate to form an ultrasonic beam.
