TECHNICAL FIELD
[0001] The utility model relates to the microfossil scientific research technical field, relates to the rock processing device containing important radiolarian fossils, specifically relates to a drop dissolving device for radiolarian fossil processing. BACKGROUND
[0002] As the single-cell protist planktonic for life, radiolarians have complex and variable skeleton structures, and are widely distributed in the global oceans, with a history dating back to the Cambrian. Therefore, radiolarians not only attract the close attention of modern marine biologists, but also become the focus of paleontologists due to their indicative significance for stratigraphic age, water depth, environment, and mineralization process. Whether morphological research or molecular biological research, obtaining complete radiolarian fossils is always one of the core tasks of the research.
[0003] As an important rock type for preserving radiolarians, siliceous rocks mainly rely on rock sectioning and surface observation methods for research on radiolarians before the discovery of the hydrofluoric acid leaching method. Due to the difficulty of dissolving siliceous rocks with other acids, the hydrofluoric acid leaching method emerged as the times require. This method mainly dissolves the surrounding rock through the reaction of hydrofluoric acid and silicon dioxide, and then neutralizes the acid through washing, thereby preserving the residues after dissolution. It should be particularly emphasized that hydrofluoric acid is highly toxic and strongly corrosive, and can cause serious harm to the human body whether inhaled or in contact with the skin, and may not produce pain at the initial stage of contact, thereby increasing the risk of injury. Therefore, strict protection of experimental personnel must be ensured during the experiment, including ensuring good ventilation conditions, wearing protective clothing, masks, gloves, and respiratory filtration devices, and preparing emergency supplies such as hexafluorine and calcium gluconate for future use.
[0004] In addition to the commonly used hydrofluoric acid leaching method, researchers have also adopted a combined treatment method of hydrochloric acid and hydrofluoric acid, that is, 15% concentration of dilute hydrochloric acid, 5% concentration of hydrofluoric acid, and 38% concentration of concentrated hydrochloric acid are sequentially added to the rock block containing radiolarian fossils to dissolve impurities and obtain fossils. In addition, there is a heavy liquid separation method that uses heavy liquid prepared from tri bromomethane and acetone to separate radiolarians.
[0005] When using chemical acids such as hydrofluoric acid and hydrochloric acid to soak and dissolve rock blocks, since these acidic substances will be in direct contact with the rock blocks and the radiolarian fossils contained therein for a long time, combined with the small size and diverse morphology of radiolarian fossils, including numerous fine structures such as radiating spines, it is inevitable that the fossils will be eroded, making it difficult to completely separate the fossils from the rock blocks.
[0006] No matter the commonly used hydrofluoric acid digestion method, or the hydrochloric acid-hydrofluoric acid treatment method and heavy liquid separation method, since the rock block needs to be soaked in the configured chemical solution for a long time, only the chemical acidic substance with relatively low concentration can be selected, which leads to slow chemical reaction process, long processing period, and easy damage to the microstructure of the radiolarian itself.
[0007] The digestion method needs to soak the rock block, and then screen the radiolarian fossils in the dissolved residue, which not only consumes a large amount of manpower and time cost, but also easily causes pollution and confusion in the selection of fossils in the residue, and easily damages the integrity of the fossils. The heavy liquid required by the heavy liquid separation method is expensive, and the loss in the operation process is large.
[0008] In view of the above problems, the application provides a dripping dissolution device for radiolarian fossil treatment, which effectively solves the problems of easy damage to the microstructure of the radiolarian and low reliability of the fossils in the digestion method in the prior art.

[0048] Referring to the drawings shown in the specification, the present application provides a droplet dissolving device for treating radioactive insect fossils, which comprises a comprehensive experiment table, a device box 4, a rock block placing module 5 and a droplet bottle.

Of course, other mesh screens can also be selected according to the needs of the experiment.
[0051] The dripping bottle comprises a dripping bottle body 8, the upper end of the dripping bottle body 8 is a liquid loading port 82, the lower end is a dripping observation port 84, a lengthened dripping bottle nozzle 85 is fixed at the lower end of the dripping observation port 84, a rotary adjusting valve 83 is arranged between the dripping bottle body 8 and the lower end dripping observation port 84, and is used for adjusting the size of the liquid outflow channel, so as to control the dripping speed. The dripping observation port 84 is convenient for observing the dripping speed, and avoids the risk of liquid splashing when directly observing the dripping speed at the nozzle. The lengthened dripping bottle nozzle 85 is designed for precise dripping, and reduces the risk of liquid splashing in the experimental process. Specifically, the diameter of the dripping bottle body 8 is 5 cm, the bottle body height is 5 cm, and the length of the lengthened dripping bottle nozzle 85 is 8 cm. The liquid loading port 82 is provided with a bolt cover 81, which is convenient for loading and pouring liquid.
[0052] The assembly and experimental process of the dripping device for radiolarian fossil treatment are as follows:
[0053] (1) Knock the rock to be treated to obtain a relatively flat surface, and the length and width of the rock sample are not greater than 3 cm. Six samples, rock block placing modules and dripping bottles are selected.
[0054] (2) According to the sample sampling, a 300-mesh hanging ear type screen 7 is selected and arranged in the rock block placing module 5 through a hanging ear handle 71.
[0055] (3) Put the rock with flat side up on the screen of the rock placing module 5, and then put the rock placing module 5 into the device box 4;
[0056] (4) Select the concentration of hydrofluoric acid according to the lithology and the rarity of fossils. For extremely rare and complex radiolarian fossils, 10% concentration of hydrofluoric acid is recommended. Generally, 40% concentration of concentrated hydrofluoric acid (the higher the concentration, the shorter the reaction time) can be selected. Put the selected hydrofluoric acid into the droplet bottle.
[0057] (5) Adjust the position of the droplet bottle support 26 on the comprehensive experiment table, place the droplet bottle containing hydrofluoric acid on the droplet bottle support 26, adjust the position of the droplet bottle so that the extended droplet bottle nozzle 85 is located directly above the target rock, and twist the rotary adjusting valve 83 to adjust the droplet speed.
[0058] (6) After a period of time, close the rotary adjusting valve 83 of the droplet bottle, move the magnifying glass 33, and observe the reaction progress and the exposure of fossils. Move the droplet bottle in time to make the acid and the rock fully react. The droplet time is determined according to the acid selection.
[0059] (7) If the fossils are not completely exposed, continue to drip; if the fossils are exposed, replace the droplet bottle containing clean water to dilute the rock, until it is neutral.
[0060] (8) Take out the rock, and observe it carefully using a binocular microscope.
[0061] (9) Coat the rock as a whole, and move it into a scanning electron microscope for observation and photography.
[0062] During the above operation process, it needs to be noted that: since hydrofluoric acid is highly toxic, during the experiment process involving hydrofluoric acid, it is particularly necessary to strictly protect the experiment personnel, including ventilation, protective clothing, mask, gloves, breathing filter device, and prepare hexafluorine and calcium gluconate for emergency treatment.
[0063] It should be understood that the present application does not limit its application to the detailed structure and arrangement of the components presented herein. The present application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of the present application.
