Description
Technical Field
The utility model relates to the technical field of bronze ware cleaning, in particular to a device for cleaning bronze ware in a nondestructive mode.
Background
The relics are remains and remains left in the historic development process of human beings, and have important archaeological values. However, these precious relics are inevitably damaged to varying degrees after thousands of years of both natural weathering, including natural factors such as rain and snow, sand, dust, smoke, soluble salts, organisms and microorganisms, and also including artifacts such as smearing, scoring, soot, acid rain, improper retooling and reinforcement, and the like, leaving a wide variety of contaminants and blots.
Cleaning is an important link of cultural relic restoration, and aims to remove various pollutants and marks, reduce and preserve the historical value of the cultural relic as much as possible. At present, physical cleaning, chemical cleaning, ultrasonic cleaning, laser cleaning, dry ice cleaning and other methods are mainly adopted for cleaning cultural relics. The chemical cleaning mainly uses acid materials such as oxalic acid, citric acid, acetic acid and the like, complexing materials such as sodium hexametaphosphate, EDTA disodium salt and the like, alkaline materials such as sodium carbonate and the like, oxidizing materials such as 84 disinfectant and hydrogen peroxide and the like, and the chemical substances tend to irreversibly corrode the surface of the cultural relics while cleaning, so that the cultural relics are damaged. The physical cleaning mainly adopts a mechanical means to physically erase, and uses a dust collector, a brush, a flap, sticky, wiping and the like to directly remove dirt or adopts a mechanical electric tool to remove hard pollutants, so that the defect is that the pollutants on the surface of the cultural relics are difficult to thoroughly clean, and the electric tool can possibly damage the cultural relics. The cleaning methods such as laser and dry ice have respective defects, for example, laser cleaning irradiates the surface of an object by using high-frequency high-energy laser pulse, the instantaneously focused laser energy causes instantaneous evaporation or stripping of pollutants on the surface, the substrates of cultural relics can be possibly damaged, the dry ice cleaning needs a high-pressure cleaning machine, the equipment requirement is high, and the application range is small.
Ultrasonic cleaning is to utilize cavitation, acceleration and direct flow of ultrasonic wave in liquid to directly and indirectly act on liquid and dirt to disperse, emulsify and strip dirt layer for cleaning. Cavitation and direct flow are more commonly used in all ultrasonic cleaners. The ultrasonic wave has high frequency and short wavelength, so that the propagation directivity is good and the penetrating power is strong, which is why the ultrasonic cleaner is designed and manufactured. Ultrasonic cleaning belongs to physical cleaning, is green cleaning per se, belongs to combined cleaning if proper cleaning agents are added into cleaning fluid, has obvious cleaning effect, and is very suitable for cleaning the surfaces of some cultural relics.
Bronze is an alloy with copper, tin and lead as main components, and is subjected to long-time oxidation effect both in the prior art and the earth, so that various corrosion coatings with different colors are naturally formed, and harmful rust is extremely damaged on the bronze, so that the bronze rust removal repair is very important. The aim of cleaning and rust removal of the copper relics is mainly to better read historical information such as textures, inscriptions and various casting marks left by the copper relics, remove corrosive substances such as unstable harmful rust on the surfaces of the copper relics, restore the surfaces and the processed original appearance of the copper relics, show the historical originality of the copper relics, and provide the truest and most reliable information for the research of the current social politics, economy and culture of the relevant staff such as Wen Bo. The cleaning and rust removal of copper cultural relics can be divided into two types, namely physical rust removal and chemical rust removal. The physical rust removing method mainly adopts a surgical knife, a miniature dental drill and ultrasonic vibration to remove scaling and rust matters on metal cultural relics. The chemical method for removing rust is to use chemical medicines such as citric acid, glycolic acid, ethylenediamine tetraacetic acid, sodium nitrite, ethanol, acetone, sodium dithionate solution, citric acid-thiourea compound solution, trisodium bicarbonate solution and the like, wherein the temperature is about 35 ℃ and the pH is controlled between 6 and 7, so that the purposes of removing scaling and harmful rust on the surface of the copper cultural relics are achieved. The disadvantage of this method is that it may cause excessive cleaning or residue effects, and the control of the amount of the drug at the time of use is a difficult problem.
In summary, there is no system for cleaning bronze-type relics that is relatively thorough and friendly.

Notably, are:
the micro-nano bubble cleaning cultural relics mainly depend on strong energy generated when bubbles break down in a dynamic state, and a part of dirt layers on the surface of the cultural relics are peeled off, dispersed, emulsified and shed under the action of shock waves.
In the present application: adding a proper amount of cleaning agent into the micro-nano bubble water, and combining ultrasonic waves under the dynamic disturbance state of the water body to clean harmful rust on the surface of the cultural relics. In the process, micro-nano bubbles are formed, grown and closed, high pressure is generated at the moment of cracking, and the instant high pressure is continuously generated by continuous cracking like a series of small 'explosion' to continuously impact the surface of the cultural relics, so that dirt on the surface of the cultural relics and in gaps is rapidly peeled off, and the aim of purifying the surface of the cultural relics is fulfilled. On one hand, the adsorption of dirt and the surface of a cleaning piece is destroyed, on the other hand, fatigue damage of a dirt layer can be caused to be refuted, the solid surface is scrubbed by vibration of gas type bubbles, once the dirt layer is slotted and drillable, the bubbles can enter the vibration to enable the dirt layer to fall off. The gaps and gaps between the dirt layer and the surface layer formed by impact are permeated, and the small bubbles are repeatedly acted on the dirt layer due to expansion and contraction, so that the dirt layer is peeled layer by layer, and bubbles continue to permeate inwards until the dirt layer is completely peeled. Meanwhile, the dissolution process of dirt can be enhanced by adding disturbance and a proper amount of cleaning agent, and the chemical force and the physical force are combined, so that the cleaning process is accelerated. Wherein the chemical action of the cleaning medium can accelerate the ultrasonic wave and micro-nano bubble cleaning effect.
The bronze cultural relics are sufficiently and thoroughly cleaned by combining micro-nano bubbles, ultrasonic waves and chemical reagents.
The lower the ultrasonic frequency is, the easier cavitation is generated in the liquid, the larger the generated force is, the stronger the effect is, the ultrasonic cleaning device is suitable for coarse, dirty and primary cleaning of workpieces, the higher the frequency is, the stronger the ultrasonic directivity is, and the ultrasonic cleaning device is more suitable for cleaning fine objects.
In the present application: two or more than three transducers with different frequencies are arranged in the ultrasonic cleaning water tank 7, and the transducers with the respective frequencies are respectively pushed by a plurality of generators. When the operating frequency of the ultrasonic cleaning tank 7 is high, the cavitation density is high when the liquid cavitation intensity is low, and the opposite is true when the operating frequency is low. The low-frequency ultrasonic wave has high intensity, is beneficial to cleaning the surface of an object, has high cavitation density, and can penetrate through the fine structures such as grooves, slits, deep holes and the like. Meanwhile, the ultrasonic cleaning water tank 7 has ultrasonic waves with various frequencies, and the problem of uneven cleaning caused by a single-frequency cleaning standing wave field is also solved. In addition, the sweep frequency and the frequency hopping cleaning can be selected to improve the sound field structure in the ultrasonic cleaning water tank 7. The sweep frequency solves the uneven standing wave field in the ultrasonic cleaning water tank 7, so that the cleaning is uniform. The frequency hopping and the multi-frequency are both carried out on high and low frequency cleaning, except that the frequency hopping is carried out by an ultrasonic transducer and an ultrasonic generator, the ultrasonic transducer has two resonant frequencies, continuous frequency change is carried out in the bandwidth of a first resonant point, then the frequency hopping is carried out in the other bandwidth, and the frequency sweeping cleaning is carried out alternately on high and low frequencies.
