Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of scientific research on micropaleontological fossils, and relates to a rock processing device containing important radiolarian fossils, and specifically relates to a dripping dissolution device for radiolarian fossil processing. Background Art
[0002] As single-celled protozoa that are planktonic throughout their lives, radiolarians have complex and variable skeletal structures and are widely distributed in the world's oceans. Their history can be traced back to the Cambrian period. Therefore, radiolarians not only receive close attention from modern marine biologists, but also become the key objects of study for paleontologists due to their indicative significance for stratigraphic age, water depth, environment, and mineralization processes. Whether it is morphological research or molecular biology research, obtaining complete radiolarian fossils has always been one of the core tasks of research.
[0003] As an important rock type for preserving radiolarians, before the discovery of the hydrofluoric acid leaching method, the research on radiolarians in it mainly relied on rock sectioning and surface observation methods. Since siliceous rocks are difficult to be dissolved by other acids, the hydrofluoric acid leaching method came into being. This method mainly dissolves the surrounding rock through the reaction of hydrofluoric acid with silicon dioxide, and then neutralizes the acidity by flushing to retain the residue after dissolution. It should be particularly emphasized that hydrofluoric acid is highly toxic and corrosive, and inhalation or skin contact will cause serious harm to the human body, and there may be no pain during initial contact, thus increasing the risk of harm. Therefore, during the experiment, it is necessary to strictly protect the experimental personnel, including ensuring good ventilation conditions, wearing protective clothing, masks, gloves, and respiratory filtration devices, and preparing first-aid supplies such as hexafluorine and calcium gluconate for emergencies.
[0004] In addition to the commonly used hydrofluoric acid leaching method, some researchers have also adopted the combined treatment method of hydrochloric acid and hydrofluoric acid, that is, adding dilute hydrochloric acid with a concentration of 15%, hydrofluoric acid with a concentration of 5%, and concentrated hydrochloric acid with a concentration of 38% to the rock block containing radiolarian fossils in sequence to dissolve impurities and obtain fossils. In addition, there is also the heavy liquid separation method that uses a heavy liquid prepared from tribromomethane and acetone to separate radiolarians.
[0005] When using chemical acidic substances such as hydrofluoric acid and hydrochloric acid to soak and dissolve the rock block, since these acidic substances will be in direct contact with the rock block and the radiolarian fossils in it for a long time, and the radiolarian fossils are tiny and have diverse morphologies, including many fine structures such as radial spines, it is inevitable that the fossil body will be corroded, making it difficult to completely separate the fossil morphology from the rock block.
[0006] Whether it is the commonly used hydrofluoric acid leaching method, the hydrochloric acid-hydrofluoric acid treatment method or the heavy liquid separation method, since the rock blocks need to be soaked in the prepared chemical solution for a long time, only relatively low-concentration chemical acidic substances can be selected, which results in a slow chemical reaction process, a long treatment cycle, and is extremely likely to damage the fine structure of the radiolarians themselves.
[0007] For the leaching method, after soaking the rock blocks, radiolarians fossils need to be screened from the dissolved residues. This process not only consumes a large amount of manpower and time costs, but also is extremely likely to cause pollution and confusion when selecting fossils from the residues, and is likely to damage the integrity of the fossils. The heavy liquid required for the heavy liquid separation method is expensive, and the loss during the operation process is relatively large.
[0008] In view of the above problems, the present application provides a dropping dissolution device for processing radiolarians fossils, which effectively solves the problems of extremely easy damage to the fine structure of radiolarians and low credibility of fossils in the existing leaching method. Summary of the Invention
[0009] One of the main objects of the present invention is to overcome at least one defect in the prior art and provide a dropping dissolution device for processing radiolarians fossils.
[0010] In order to achieve the above technical solution, the present invention adopts the following technical solutions:
[0011] According to one aspect of the present invention, there is provided a dropping dissolution device for processing radiolarians fossils, including a comprehensive experimental bench, a device box, a rock block placement module, and a dropping liquid bottle;
[0012] Among them, the comprehensive experimental bench includes a base, a first vertical rod is provided on the base, and a dropping liquid bottle support assembly is fixed on the first vertical rod through a sleeve. The dropping liquid bottle support assembly includes a cross bar fixedly connected to the sleeve, and the other end of the cross bar is fixedly connected with a dropping liquid bottle support through a screw connection head. The dropping liquid bottle is fixed on the comprehensive experimental bench through the dropping liquid bottle support;
[0013] It further includes a second vertical rod, a third vertical rod is sleeved on the second vertical rod, so that the third vertical rod can rotate left and right; the other end of the third vertical rod is connected with a fourth vertical rod, and a magnifying glass connected to the fourth vertical rod; among them, multi-angle rotatable joint devices are connected between the third vertical rod and the fourth vertical rod, and between the fourth vertical rod and the magnifying glass; through the multi-angle rotatable joint devices, the magnifying glass can move in the front-back, left-right and up-down directions at multiple angles, and can meet the focusing and magnification requirements needed for observing during the dropping dissolution reaction process;
[0014] A device box is provided on the base, and several rock placement modules are provided inside the device box; the upper part of the rock placement module has an opening, a drawer-type waste liquid tank is provided at the lower part, and a hanging ear type screen is provided inside the rock placement module; the hanging ear type screen can not only place fossil rocks to facilitate the dripping of waste liquid, but also effectively screen out fine impurities and retain the radiolarians fossils after dissolution by dripping.
[0015] In this application, through the dripping dissolution device, the reaction process between the acidic substance and the rock can be directly observed, so as to adjust the reaction speed in time; by controlling the reaction process and observing at any time, the dripping dissolution device can obtain important radiolarians fossils completely and in-situ; the dripping dissolution device uses the dripping method to corrode the rock, reducing the amount of acid used and lowering the economic cost.
[0016] According to an embodiment of the present invention, the hanging ear type screen is fixed by a hanging ear handle provided on the rock placement module; the design of the hanging ear handle is convenient for easy lifting, reducing the risk of contact with the liquid and also reducing the risk of liquid splashing.
[0017] According to an embodiment of the present invention, the length of the base is 50 cm and the width is 40 cm; the length of the device box is 30 cm, the width is 20 cm, and the height is 15 cm.
[0018] According to an embodiment of the present invention, the dropper bottle holder is in a circular ring shape, and an opening is provided at one end far from the screw connection head, adopting a non-closed design, which is convenient for operating the dropper bottle.
[0019] According to an embodiment of the present invention, the device box is a rectangular box with an opening at the top.
[0020] According to an embodiment of the present invention, the number of the rock placement modules is preferably six.
[0021] According to an embodiment of the present invention, the rock placement module is a square box with an opening at the top.
[0022] According to an embodiment of the present invention, the length and width of each rock placement module are both 9 cm, and the height is 14 cm. The rock placement module is made of transparent polypropylene, which is not only resistant to hydrofluoric acid corrosion, but also convenient for observation; each rock placement module can be extracted separately, which is convenient for operation and maintenance.
[0023] According to an embodiment of the present invention, the hanging ear type screen is one of a 300-mesh screen and a 400-mesh screen. Generally, a 300-mesh screen is used; if the sampling time of the rock is earlier and the radiolarians fossils are smaller, a 400-mesh screen is used.
[0024] According to an embodiment of the present invention, the dropping bottle includes a dropping bottle body. The upper end of the dropping bottle body is a liquid filling port, and the lower end is a dropping observation port. A lengthened dropping bottle nozzle is fixed at the lower end of the dropping observation port.
[0025] A rotary regulating valve is provided between the dropping bottle body and the lower dropping observation port to adjust the size of the liquid outflow channel, thereby controlling the dropping speed.
[0026] Among them, the dropping observation port facilitates observing the dropping speed and at the same time avoids the danger brought by liquid splashing when observing the dropping speed directly at the nozzle. The design of the lengthened dropping bottle nozzle is used for accurate dropping, reducing the danger brought by liquid splashing during the experiment.
[0027] According to an embodiment of the present invention, the diameter of the dropping bottle body is 5 cm, the height of the bottle body is 5 cm, and the length of the lengthened dropping bottle nozzle is 8 cm.

[0031] From the above technical solutions, it can be seen that the present invention has at least one of the following advantages and positive effects:
[0032] Since radiolarians fossils have fine structures such as radial spines and relatively few representative fossils with paleoenvironmental and stratigraphic significance, the dropping and dissolving device made of polypropylene material in the present invention shows significant advantages in the extraction process of rare radiolarians fossils. The dropping and dissolving device described in the present application controls the process of chemical reaction by precisely regulating the dropping speed and the dissolving position, and allows the experimenter to observe at any time, so as to obtain the fossil completely and in-situ. By using the dropping and dissolving device described in the present application, not only impurities and pollution are effectively excluded, the credibility of the fossil is significantly improved, but also more detailed observation is possible. In addition, the application of the dropping and dissolving method greatly reduces the amount of acid used, thereby reducing the economic cost of the experiment.
[0033] The drip dissolution device of the present invention is targeted at the extraction of rare radiolarian fossils and demonstrates excellent performance. It precisely regulates the dripping rate and the corrosion position, ensuring the complete extraction and in-situ observation of fossils, effectively removing the surrounding rock, and improving the extraction efficiency of important fossils. At the same time, the drip dissolution technology reduces the acid consumption and lowers the cost. The drip dissolution device of the present invention not only provides technical support for the research of radiolarian fossils, but also significantly enhances the safety design.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.
[0048] As shown in the accompanying drawings of the specification, the present invention provides a dripping and dissolving device for radiolarians fossil processing, including a comprehensive experimental bench, a device box 4, a rock block placement module 5, and a dropping liquid bottle.
[0049] The comprehensive experimental bench includes a base 1 with a length of 50 cm and a width of 40 cm. A first vertical rod 2 is provided on the base 1, and a dropper bottle support assembly is fixed on the first vertical rod 2 through a sleeve 23. The dropper bottle support assembly includes a cross bar 24 fixedly connected to the sleeve 23, and the other end of the cross bar 24 is fixedly connected with a dropper bottle support 26 through a screw connector 25.

Integrating the magnifying glass 33 on the comprehensive experimental bench can not only observe the reaction process at any time, but also, since the dripping and dissolving treatment of radiolarians involves hydrofluoric acid, a highly toxic acidic substance, fixing the magnifying glass can prevent the danger caused by acid droplets splashing when personnel hold it for observation.
[0050] A device box 4 is provided on the base 1. The length of the device box is 30 cm, the width is 20 cm, and the height is 15 cm.

The upper part of the rock placement module 5 has an opening, and a drawer-type waste liquid tank 6 is provided at the lower part. When the waste liquid tank 6 is replaced, it is convenient to pour out the waste liquid in time. A hanging ear type screen 7 is provided in the rock placement module 5; the hanging ear type screen 7 can not only place the fossil rock blocks to facilitate the dripping of the waste liquid but also effectively screen out fine impurities and retain the radiolarians fossils after dissolution by dripping. The hanging ear type screen 7 is fixed by a hanging ear handle 71 provided on the rock placement module 5; the design of the hanging ear handle 71 is convenient for lifting easily, reducing the risk of contact with the liquid and also reducing the risk of liquid splashing. The hanging ear type screen 7 is one of a 300-mesh screen and a 400-mesh screen. Generally, a 300-mesh screen is used; if the sampling time of the rock block is earlier and the radiolarians fossils are smaller, a 400-mesh screen is used. Of course, other mesh screens can also be selected according to the experimental requirements.
[0051] The dropping bottle includes a dropping bottle body 8. The upper end of the dropping bottle body 8 is a liquid filling port 82, and the lower end is a dropping observation port 84. A lengthened dropping bottle nozzle 85 is fixed at the lower end of the dropping observation port 84; a rotary regulating valve 83 is provided between the dropping bottle body 8 and the lower dropping observation port 84 for adjusting the size of the liquid outflow channel so as to control the dropping speed; the dropping observation port 84 is convenient for observing the dropping speed and at the same time avoids the danger of liquid splashing when observing the dropping speed directly at the nozzle; the design of the lengthened dropping bottle nozzle 85 is for accurate dropping and reduces the danger of liquid splashing during the experiment. Specifically, the diameter of the dropping bottle body 8 is 5 cm, the height of the bottle body is 5 cm, and the length of the lengthened dropping bottle nozzle 85 is 8 cm. There is a bolt cover 81 at the liquid filling port 82, which is convenient for filling and pouring the liquid.
[0052] The assembly and experimental process of a dropping and dissolving device for radiolarians fossils according to the present invention are as follows:
[0053] (1) Knock a relatively flat surface on the rock to be processed. The length and width dimensions of the rock sample do not exceed 3 cm. Select six samples, as well as the number of rock placement modules and dropping bottles.
[0054] (2) According to the sample sampling, select a 300-mesh hanging ear type screen 7 and set it in the rock placement module 5 through the hanging ear handle 71.
[0055] (3) Place the relatively flat side of the rock facing upwards on the screen of the rock placement module 5, and then place the rock placement module 5 into the device box 4;
[0056] (4) Select the concentration of hydrofluoric acid according to the lithology and the rarity of the fossils. For extremely rare and structurally complex radiolarian fossils, it is recommended to use hydrofluoric acid with a concentration of 10%. Generally, concentrated hydrofluoric acid with a concentration of 40% can be selected (the higher the concentration, the shorter the reaction time). Fill the selected hydrofluoric acid into a dropping bottle.
[0057] (5) Adjust the position of the dropping bottle holder 26 on the comprehensive experimental bench, place the dropping bottle filled with hydrofluoric acid on the dropping bottle holder 26, adjust the position of the dropping bottle so that the extended dropping bottle nozzle 85 is directly above the target rock, and turn the rotary regulating valve 83 to adjust the dropping speed.
[0058] (6) After dropping for a period of time, close the rotary regulating valve 83 of the dropping bottle, move the magnifying glass 33, observe the reaction process and the exposure of the fossils, and move the dropping bottle in a timely manner to make the acid and the rock react fully. The dropping time is determined according to the acidity.
[0059] (7) If the fossils are not completely exposed, continue to drop; if the fossils are exposed, replace the dropping bottle filled with clear water to dilute the rock until it is neutral.
[0060] (8) Take out the rock and carefully observe it with a binocular microscope.
[0061] (9) Coat the whole rock with a film, move it into a scanning electron microscope for observation and photography.
[0062] During the above operation process, it should be noted that: Since hydrofluoric acid is highly toxic, during the experiment involving hydrofluoric acid, it is particularly necessary to strictly protect the experimental personnel, including ventilation, protective clothing, face masks, gloves, respiratory filtration devices, and prepare hexafluorine and calcium gluconate for use in emergency treatment.
[0063] It should be understood that the present invention does not limit its application to the detailed structure and arrangement of the components proposed in this article. The present invention 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 invention. It should be understood that the present invention disclosed and defined in this article extends to all alternative combinations of two or more separate features mentioned or apparent in the text and / or drawings.
