Description

Technical Field

[0001] This utility model relates to the field of palm leaf scripture protection technology, and in particular to a fumigation treatment device for palm leaf scripture cultural relics. Background Technology

[0002] Palm-leaf manuscripts are a form of written text created using the leaves of specific palm trees such as palm palm and sugar palm. Due to the unique nature of their material, palm-leaf manuscripts are susceptible to environmental changes or improper use during preservation, leading to problems such as leaf adhesion, deformation, and mold growth.

[0003] Regarding the issues of palm leaf adhesion and deformation, the usual conservation procedure involves first softening the leaves appropriately to restore their resilience before peeling and stretching them. For mold and insect infestations, fumigation with organic reagents or in a low-oxygen environment is used for disinfection. Traditional conservation methods often involve solvent soaking or boiling / fumigating with water and solvents. While these methods can soften and biologically disinfect the palm leaves, they suffer from problems such as inaccurate temperature control, excessive fumigant, and contamination by disinfectants, posing risks to the safety of both the artifacts and conservation personnel.

[0004] Ultrasonic atomization technology is a common atomization fumigation method. However, existing ultrasonic atomization fumigation devices cannot meet the requirements of synchronous and uniform wetting within the wetting range of the palm leaf scripture (approximately 40cm × 7cm in size). The dosage and temperature of the fumigant are difficult to control precisely, resulting in unsatisfactory fumigation effects. Problems include excessive diffusion of atomized reagents, damage to palm leaf scripture artifacts during the fumigation process, long processing time and high difficulty in achieving the softening effect, and difficulty in recovering harmful reagents after fumigation.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Furthermore, it should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0030] See Figure 1 As shown, this utility model provides a device for fumigating palm leaves used in cultural relic treatment, comprising:

[0031] Processing chamber 1, the processing chamber 1 is provided with a platform 11 for placing the palm leaf scripture to be processed;

[0032] The fumigant supply mechanism 2 includes a water bath cavity 21, a heating element 22 for heating the liquid in the water bath cavity, and a thin-walled container 23 for storing the fumigant. An ultrasonic atomizer 24 is provided below the water bath cavity 21, and the thin-walled container 23 is at least partially placed inside the water bath cavity 21.

[0033] The main conveying channel 3 is connected at both ends to the interior of the processing chamber 1 and the interior of the thin-walled container 23, respectively.

[0034] The gas conveying mechanism 4 can convey gas to the main conveying channel 3. The gas conveying mechanism 4 is connected to the end of the main conveying channel 3 near the thin-walled container 23.

[0035] During fumigation, the fumigation leaf to be treated is placed on the platform 11 in the treatment chamber 1. The ultrasonic atomizer 24 atomizes the liquid in the water bath 21 using ultrasonic atomizer, while the heating element 22 heats the liquid to a preset temperature. The fumigation reagent in the thin-walled container 23 is atomized and heated to the required temperature. Subsequently, the atomized fumigation reagent is input into the treatment chamber 1 through the main conveying channel 3. At the same time, the gas conveying mechanism 4 can convey gas to the main conveying channel 3, thereby controlling the flow rate after atomization in the fumigation design, improving the dispersion effect of the atomized reagent in the treatment chamber 1, and ensuring that it evenly covers the fumigation leaf.

[0036] In addition, when fumigation is not required, the passage between the thin-walled container 23 and the main conveying channel 3 can be closed, and a drying airflow can be conveyed into the main conveying channel 3 through the gas conveying mechanism 4 to dry the palm leaves in the treatment chamber 1. Alternatively, an inert gas can be conveyed into the main conveying channel 3 through the gas conveying mechanism 4 to create a low-oxygen environment for insecticidal treatment of the palm leaves in the treatment chamber 1.

[0037] In this invention, on the one hand, the fumigation reagent is stored in a thin-walled container 23 with extremely thin walls, and the thin-walled container 23 is immersed in water in a water bath cavity 21. The ultrasonic atomizer 24 and the heating element 22 act on the water in the water bath cavity 21 and transfer it to the fumigation reagent in the thin-walled container 23, making the atomized droplet size and temperature of the fumigation reagent more uniform, and making the atomized dosage and temperature of the fumigation reagent easier to control, so that the fumigation leaves can be evenly wetted. On the other hand, a gas delivery mechanism 4 is provided to deliver gas to the main delivery channel 3. Furthermore, by controlling the flow rate after atomization in the fumigation design, the fumigation effect is further improved. Therefore, this invention, through the combination of the fumigant supply mechanism 2 and the gas delivery mechanism 4, can better regulate the atomization intensity and temperature of the fumigant, and make the atomized droplet size and temperature of the fumigant more uniform, resulting in better fumigation effect. This effectively solves the problems of excessive diffusion of atomized reagents, damage to palm leaf artifacts during the fumigation process, and the long processing time and difficulty in achieving the softening effect found in existing atomization devices applied to palm leaf fumigation. It can meet the specific needs of palm leaf fumigation treatment. Simultaneously, the thin-walled container 23, the main delivery channel 3, and the treatment chamber 1 form a relatively closed system, facilitating the centralized recovery of harmful reagents after fumigation.

[0038] In some embodiments, see Figure 1 As shown, the main delivery channel 3 includes a reagent inlet and a gas inlet. The reagent inlet is connected to the interior of the thin-walled container 23, and a first control valve is provided between the reagent inlet and the thin-walled container 23. The gas inlet is connected to the gas delivery mechanism 4, and a second control valve is provided between the gas inlet and the gas delivery mechanism 4.

[0039] By installing control valves between the thin-walled container 23 and the reagent inlet of the main delivery channel 3, and between the gas delivery mechanism 4 and the gas inlet of the main delivery channel 3, the passage between the thin-walled container 23 and the main delivery channel 3, and the passage between the gas delivery mechanism 4 and the main delivery channel 3 can be controlled by opening and closing the control valves. The flow rate of gas and atomized reagent entering the main delivery channel 3 can be further regulated by adjusting the opening degree of the control valves, thereby controlling the dosage and flow rate of the atomized reagent and improving the fumigation effect.

[0040] In some embodiments, the gas delivery mechanism 4 may further include a gas flow meter capable of cooperating in regulating the flow rate of the gas flow.

[0041] In some embodiments, the relative height distance between the bottom of the thin-walled container 23 and the ultrasonic atomizer 24 is less than or equal to 1.5 cm, and / or the thickness of the thin-walled container 23 is 0.055 mm to 0.060 mm.

[0042] Within this range, the relative height distance between the bottom of the thin-walled container 23 and the ultrasonic atomizer 24 is small, and the thickness of the thin-walled container 23 is thin, which can reduce the transmission loss of ultrasonic energy in the liquid of the water bath cavity 21 while ensuring the uniformity of the atomized droplet size.

[0043] In some embodiments, the thin-walled container 23 is made of plastic, preferably PFA.

[0044] In some embodiments, the thin-walled container 23 is connected to the main output channel via a sealing snap to facilitate the replacement of the thin-walled container 23.

[0045] In some embodiments, the ultrasonic atomizer 24 is located directly below the thin-walled container 23 to reduce the transmission loss of ultrasonic energy in the liquid of the water bath cavity 21 while ensuring the uniformity of the particle size of the atomized fumigation reagent.

[0046] In some embodiments, the water bath cavity 21 has an inlet and an outlet to facilitate water replacement.

[0047] In some embodiments, see Figure 1 , Figures 3 to 4 As shown, the storage platform 11 includes a storage partition 111 with several through holes arranged on it. The storage partition 111 divides the processing chamber 1 into an upper processing chamber 13 and a lower recovery chamber 14. The upper processing chamber 13 is equipped with a fluid nozzle 15, which is connected to the main conveying channel 3. A cooling component 16 is provided below the lower recovery chamber 14, and the lower recovery chamber 14 is connected to a waste liquid recovery container.

[0048] During fumigation, the reagent atomized droplets of the mixed gas are transported to the treatment chamber 1 through the main conveying channel 3 and the fluid nozzle 15. The through-hole design of the partition plate 111 can effectively increase the contact area between the surface of the palm leaf to be treated and the fumigation reagent. The bottom of the palm leaf can also fully contact the fumigation reagent, ensuring that the upper and lower surfaces of the palm leaf can be evenly wetted. At the same time, it allows excess fumigation reagent to settle into the lower recovery chamber 14 below the partition plate 111, and condense back into liquid under the cooling effect of the cooling element 16. It is then recycled to the waste liquid recovery container, making the centralized recovery of harmful reagents after fumigation more convenient and safer.

[0049] In some embodiments, see Figure 1 As shown, the side wall of the lower recovery chamber 14 is provided with a recovery outlet 141, which is connected to a waste liquid recovery container (not shown).

[0050] When the liquid waste in the current recovery chamber 14 reaches the height of the recovery outlet 141, it can automatically flow to the waste liquid recovery container, making the centralized recovery of harmful reagents after fumigation more convenient.

[0051] In some embodiments, see Figure 3 As shown, the shelf 111 is also provided with a magnetic pressing block 12 for pressing and fixing the palm leaf to be processed. The shelf 111 is made of magnetic material.

[0052] For example, either the shelf 111 or the magnetic pressure block 12 can be a magnet, and the other can be a magnetic metal such as iron, cobalt, or nickel.

[0053] By using the magnetically connected shelf 111 and magnetically attached block 12, the basil can be stably fixed on the shelf 111, preventing the basil from shifting due to airflow. The magnetically attached block 12 is easy and quick to use, and can fix the basil at any position on the shelf 111, offering high flexibility and strong applicability.

[0054] In some embodiments, see Figure 1 As shown, the cooling component 16 includes a refrigeration assembly and a cooling platform 161, which is parallel to and in contact with the bottom of the lower recovery chamber 14.

[0055] The cooling effect is improved by having the cooling platform 161 parallel to and tightly fitted to the bottom of the lower recovery chamber 14.

[0056] For example, the cooling component may be a semiconductor component.

[0057] In some embodiments, see Figure 1 and Figure 5 As shown, the fluid nozzle 15 includes a cover, and an outlet end 151 is provided at the end of the cover away from the main conveying channel 3. The outlet end 151 has a rectangular structure and is provided with a number of fluid output holes 152. The cross-sectional area of ​​the cover increases sequentially in the direction away from the main conveying channel 3, and a filter membrane layer 153 is provided inside the cover.

[0058] By setting a hood with a large-sized outlet end 151 and making the outlet end 151 rectangular, it is beneficial for the atomized reagent to quickly and evenly wet the fumigation needle. The filter membrane layer 153 can filter solid impurities in the fumigation reagent, preventing solid impurities from clogging the fluid output hole 152 or contaminating the fumigation needle.

[0059] In some embodiments, the fluid nozzle 15 is adjustablely disposed within the upper processing chamber 13 in the vertical direction. For example, a telescopic bracket can be provided to fix the fluid nozzle 15, but this is not a limitation. By adjusting the height of the fluid nozzle 15, it is beneficial to control the spray range of the atomized reagent and further improve the uniformity of atomization.

[0060] In some embodiments, a temperature detector, a humidity detector, a pressure detector, etc., may also be provided in the processing chamber 1 to monitor the temperature, humidity, pressure, etc. inside the processing chamber 1 in real time, so as to ensure that the temperature, humidity and pressure inside the processing chamber 1 can be adjusted in a timely manner.

[0061] In some embodiments, see Figure 1 As shown, the gas conveying mechanism 4 includes a gas supply source (not shown) and a gas flow input branch pipe 41. The two ends of the gas flow input branch pipe 41 are connected to the gas supply source and the main conveying channel 3, respectively.

[0062] In some embodiments, see Figure 2 As shown, the water bath cavity 21 is provided with a sealing cover 211, and the sealing cover 211 is provided with a slot for securing the thin-walled container 23, so as to ensure that the thin-walled container 23 is stably fixed in the water bath cavity 21.

[0063] Of course, the above illustrations are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
