Problems solved by technology

[0006] Although the cleaning effect of ultrasonic cleaning is good, it is powerless to clean sub-micron dirt particles. At the same time, the size of the cleaning tank also limits the range and complexity of cleaning objects, and it is also a big problem that the cultural relics after cleaning need to be dried quickly. problem
The laser cleaning technology that has emerged in recent years is more suitable for small-scale high-precision cleaning, and has limited effect on large-scale corrosion.

Embodiment 1

[0039] This embodiment cleans the sediment disease on the surface of the high-temperature sintered ceramics with water outlet.

[0040] The No. 8 outflow ceramic piece from the No. 1 shipwreck in the South China Sea was selected, with a size of 47*31mm, and there were hard deposits on it. The main component was calcium carbonate according to Raman spectroscopic analysis. Ceramic slices before cleaning Figure 2a As shown, it can be seen that the ceramic sheet has a smooth surface and is sintered at high temperature.

[0041] Install a pump filling tank, valve and funnel at the water inlet of the dissolved air pump, and install a check valve, air flow sensor and needle valve at the air inlet. Install a pressure sensor, a pH sensor and a conductivity sensor in the water outlet pipeline of the dissolved air pump. Install a micro-nano bubble generator at the end of the outlet pipe of the dissolved air pump, and place it at the bottom of the cleaning tank. The micro-nano bubble ...

Embodiment 2

[0046] This embodiment cleans the sediment disease on the surface of the low-temperature sintered ceramics with water outlet.

[0047] Select No. 14 water-discharged ceramic piece from the No. 1 shipwreck in the South China Sea, with a size of 45*45mm, and there are hard deposits on it. The main component is calcium carbonate according to Raman spectroscopic analysis. It can be seen from the appearance of the ceramic sheet that the surface of the ceramic sheet is rough and is sintered at a low temperature.

[0048] Install a pump filling tank, valve and funnel at the water inlet of the dissolved air pump, and install a check valve, air flow sensor and needle valve at the air inlet. Install a pressure sensor, a pH sensor and a conductivity sensor in the water outlet pipeline of the dissolved air pump. Install a micro-nano bubble generator at the end of the outlet pipe of the dissolved air pump, and place it at the bottom of the cleaning tank. The micro-nano bubble generator a...

Embodiment 3

[0053] This embodiment is aimed at cleaning the water-discharging ceramics with metal erosion deposits on the surface.

[0054] Selected No. 18 water-discharged ceramic piece from No. 1 shipwreck in the South China Sea, the size is 95*59mm, and there are metal erosions on it. After X-ray fluorescence spectroscopic analysis, a relatively high content of iron element is detected. See image 3 , which is the X-ray fluorescence spectrogram of No. 18 effluent ceramic sheet.

[0055] Install a pump filling tank, valve and funnel at the water inlet of the dissolved air pump, and install a check valve, air flow sensor and needle valve at the air inlet. Install a pressure sensor, a pH sensor and a conductivity sensor in the water outlet pipeline of the dissolved air pump. Install a micro-nano bubble generator at the end of the outlet pipe of the dissolved air pump, and place it at the bottom of the cleaning tank. The micro-nano bubble generator adopts a high-speed rotary micro-nano b...

Abstract

The invention discloses a method and device for washing historical relics from water with circulation type micro-nano bubbly water through a power pump. The method comprises the steps that air and water are pressurized and mixed through an air-liquid mixing pump, so that an air-water mixture is obtained; and then, the air-water mixture generates the micro-nano bubbly water through a micro-nano bubble generator so that the historical relics from water can be washed. According to the method and device for washing the historical relics from water with the circulation type micro-nano bubbly water through the power pump, through the efficient interfacial activity, the super-strong permeation function and the micro-bursting force of the micro-nano bubbly water are utilized to weaken the binding force between the historical relics and harmful attached impurities, the different harmful attached impurities on the historical relics are stripped, and therefore washing of the historical relics from water is completed. Compared with conventional methods of adding acid-base complexing agent, ultrasonic methods and the like, the method for washing the historical relics from water with the circulation type micro-nano bubbly water through the power pump is a pure physical cleaning method, the attached concretions on the historical relics are effectively washed away, the historical relics are not damaged meanwhile, and no environmental pollutant is generated in the processing process; and the efficiency is high, and the method can be applied to washing of the historical relics from water on a large scale.

Description

technical field [0001] The invention relates to the technical field of cleaning cultural relics discharged from water, in particular to a method and a device for cleaning cultural relics discharged from water by circulating micro-nano bubble water with a power pump. Background technique [0002] Cultural relics are non-renewable remains that carry rich information about human history and culture. In the long history, China has exported a large amount of ceramics to all over the world. As a traditional mode of transportation, sea transportation has the advantages of large quantity, safety, convenience and low freight. However, due to the frequent occurrence of shipwrecks and shipwrecks, countless ceramics for export have been left in the depths of the vast sea. With the development of underwater archaeology today, a large number of ancient Chinese ceramics have been salvaged from the ocean. Through the research on the restoration and protection of ceramic cultural relics o...
