Abstract
Description
Technical Field
[0001] The present application relates to the field of chemical instruments, and in particular to an experimental container for chemical experiments with an alarm structure. Background Art
[0002] An experimental container is a container used for chemical reactions. Since chemical reactions are usually accompanied by a large amount of heat release or heat absorption, as well as drastic changes such as precipitation, the structural strength of the experimental container is an important consideration in its preparation process. Glass itself has a high structural strength and only reacts with a small amount of reactants, so it becomes the most important experimental container in the experiment.
[0003] Due to the particularity of chemical experiments, most chemical reagents are toxic substances, and toxic substances are easily produced during the reaction process. Therefore, during the chemical experiment, once the reaction container is damaged, it is very easy to cause toxic substances to leak and induce safety accidents. Even if the experimenters deal with the damage of the reaction container in time, there is still a risk of harm spreading. Summary of the invention
[0004] The purpose of the present application is to provide an experimental container. Compared with the prior art, an experimental container for chemical experiments with an alarm structure is provided. An inner support structure matching the inner support structure is inserted through the inner side of an elastic outer jacket. A fixing ring matching the inner support structure is fixedly connected to the pipe mouth of the inner support structure. A reaction container is inserted in the fixing ring. The reaction container is placed in the inner support structure. The inner support structure includes a supporting body. A filling cavity is excavated in the supporting body. The filling cavity is filled with filling balls and a neutralizing liquid. A plurality of filling fibers are fixedly connected to the outer wall of the filling balls. The plurality of filling fibers are in a three-dimensional spiral shape. Adjacent filling fibers are entangled together. The plurality of filling balls occupy nine-tenths of the volume of the filling cavity. A shrinkage belt is fixedly connected to the outer wall of the elastic outer jacket. The shrinkage belt has a tendency to shrink, and the position of the shrinkage belt matches the uppermost end of the filling cavity.
[0005] A temperature sensor and a pressure sensor are also provided in the reaction vessel. An alarm device is fixedly connected to the outer wall of the elastic jacket. The temperature sensor and the pressure sensor are respectively connected to the alarm device signals. The temperature sensor and the pressure sensor are intelligent sensors, and the alarm device is a buzzer alarm, which has a simple and reliable structure. The temperature sensor and the pressure sensor perform simple processing on the detection data while detecting the temperature and pressure in the reaction vessel. When the temperature and pressure in the reaction vessel detected by the temperature sensor and the pressure sensor change drastically, the buzzer alarm sounds an alarm to remind researchers that a violent chemical reaction is taking place in the reaction vessel, and researchers are required to touch the experimental container less to increase the safety of the researchers. When the reaction vessel is damaged and a neutralization reaction occurs, the detection data of the temperature sensor and the pressure sensor will also change drastically. The buzzer alarm also sounds an alarm to remind researchers to stay away to avoid irreversible damage to the researchers caused by damage to the elastic jacket, thereby increasing the safety of the use of the elastic jacket. After the neutralization reaction in the elastic jacket is completed, the temperature and pressure in the elastic jacket return to normal, the buzzer alarm stops working, and the researchers can safely handle the elastic jacket.
[0006] Even if the reaction vessel is damaged, it is unlikely to cause leakage of toxic substances, induce safety accidents, or pose risks of dangerous spread.
[0007] Optionally, a reinforcing net is fixedly connected between the elastic jacket and the inner supporting structure, and one end of the reinforcing net close to the elastic jacket is embedded in the inner wall of the elastic jacket, further increasing the structural strength of the elastic jacket and the inner supporting structure, so that through cracks appear in the elastic jacket and the inner supporting structure.
[0008] Optionally, the reinforcement mesh is woven from a plurality of high-tenacity elastic fibers, so as to further increase the structural strength of the woven reinforcement mesh.
[0009] Optionally, the fixing ring includes a hard ring, the inner wall of the hard ring contacts the outer wall of the reaction container, and further positions the upper end of the reaction container, so that the reaction container is more stable during chemical experiments, less prone to shaking, and less likely to cause safety accidents.
[0010] Optionally, a plurality of disassembly grooves are chiseled at the upper end of the hard ring, and the plurality of disassembly grooves are evenly distributed on the upper side of the hard ring, further facilitating the staff to disassemble and replace the disassembly grooves.
[0011] Optionally, a positioner matching the reaction vessel is fixedly connected to the bottom plate of the inner support structure. The positioner is made of water-soluble material and is further used to fix the lower end of the reaction vessel, so that the reaction vessel is more stable during chemical experiments, less prone to shaking, and less likely to cause safety accidents.
[0012] Optionally, the positioner includes multiple fixing sleeves, and the multiple fixing sleeves are all "T"-shaped. Further, after the chemicals in the reaction container leak, the leaked chemical reagents will quickly corrode the multiple fixing sleeves, so that the fixation of the lower end of the reaction container is released. At the same time, under the action of the filling balls pouring out of the filling cavity, the reaction container will be broken and pushed to overturn, and the entire reaction container falls into the inner support structure, which is convenient for the shrinkage belt to completely tighten the opening of the elastic outer sleeve and the inner support structure.
[0013] Optionally, prefabricated grooves are bored on a plurality of fixing sleeves, and the prefabricated grooves are located at one end of the fixing sleeves away from the bottom plate of the inner supporting structure, so that the structure of the positioner corroded by chemical reagents can be quickly collapsed to release the positioning of the reaction container.
[0014] Optionally, the plurality of prefabricated grooves are all located on the outer wall of the fixing sleeve, which further makes it easy for the plurality of fixing sleeves to tilt away from the reaction container after being partially corroded, and the structure thereof is easy to collapse.
[0015] Optionally, the elastic jacket, the reinforcing net and the inner supporting structure are all made of transparent materials, and the neutralizing liquid is mixed with fluorescent liquid, which further facilitates the experimenter to observe the chemical reaction process in the reaction vessel. A small amount of fluorescent liquid can enable the experimenter to see the process of the neutralizing liquid flowing out of the inner supporting structure, and the experimenter can respond quickly.
[0016] Compared with the prior art, the advantages of this application are:
[0017] In this scheme, chemical reagents react in the reaction container, and the heat generated by the reaction will cause the temperature of the reaction container to change rapidly. At the same time, the intense chemical reaction will also impact the reaction container, causing fatigue accumulation on the reaction container. After the fatigue accumulates to a certain extent, the reaction container will rupture. The debris generated by the rupture will contain a large amount of kinetic energy, which is easy to scratch the inner wall of the supporting body, causing the neutralizing liquid filled in the filling cavity to flow out. During the process of the neutralizing liquid flowing out, some filling balls will flow out together, and multiple filling balls are partially connected by filling fibers, causing the spatial structure in the filling cavity to collapse instantly. At the same time, the locator will also collapse under the corrosion line structure of the chemical reagent and can no longer position the reaction container. At the same time, under the action of the filling balls gushing out of the filling cavity, the reaction container will be broken and pushed to overturn, so that the entire reaction container falls into the inner support structure. At this time, under the action of the shrinkage belt, the elastic jacket, the reinforcement net and the opening of the inner support structure will be tightened to form a cloth bag, complete the sealing, and facilitate subsequent recycling. Even if the reaction container is damaged, it is not easy to cause toxic substance leakage, induce safety accidents, and have the risk of dangerous spread.
[0018] The use of a positioner to fix the lower end of the reaction container makes the reaction container more stable during chemical experiments, less likely to shake, and less likely to cause safety accidents. After the chemicals in the reaction container leak, the leaked chemical reagents will quickly corrode the multiple fixing sleeves, so that the fixation of the lower end of the reaction container is released. At the same time, under the action of the filling balls gushing out of the filling cavity, the reaction container will be broken and pushed to overturn, and the entire reaction container will fall into the inner support structure, making it easier for the shrinkage belt to completely tighten the openings of the elastic outer sleeve and the inner support structure. The prefabricated grooves excavated on the outside of the multiple fixing sleeves make it easy for the multiple fixing sleeves to tilt away from the reaction container after being locally corroded, and the structure itself is prone to collapse.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0033] The first implementation method:
[0034] This application discloses an experimental container for chemical experiments with an alarm structure, please refer to Figure 1-5 The invention comprises an elastic jacket 1, an inner supporting structure 3 matching the elastic jacket 1 is inserted into the inner side of the elastic jacket 1, a fixing ring 5 matching the elastic jacket 1 is fixedly connected to the pipe mouth of the inner supporting structure 3, a reaction container 7 is inserted into the fixing ring 5, and the reaction container 7 is placed in the inner supporting structure 3, the inner supporting structure 3 comprises a supporting body 301, a filling cavity 302 is excavated in the supporting body 301, the filling cavity 302 is filled with a filling ball 303 and a neutralizing liquid, a plurality of filling fibers 304 are fixedly connected to the outer wall of the filling ball 303, the plurality of filling fibers 304 are all in a three-dimensional spiral shape, and adjacent filling fibers 304 are connected to each other. 304 are entangled together, and multiple filling balls 303 occupy nine-tenths of the volume of the filling cavity 302. A shrinkage band 4 is fixedly connected to the outer wall of the elastic jacket 1. The shrinkage band 4 has a tendency to shrink, and the position of the shrinkage band 4 matches the uppermost end of the filling cavity 302. The elastic jacket 1, the reinforcing net 2 and the inner support structure 3 are all made of transparent materials. Fluorescent liquid is added to the neutralizing liquid to facilitate the experimenter to observe the chemical reaction process in the reaction container 7. A small amount of fluorescent liquid can enable the experimenter to see the process of the neutralizing liquid flowing out of the inner support structure 3, and the experimenter can respond quickly.
[0035] It is worth noting that in this solution, the material of the support body 301 and the composition of the neutralizing liquid need to be specifically selected and need to match the chemical experiment drugs. The support body 301 is easily corroded by the drugs and products of the current chemical experiment, and the neutralizing liquid is selected to be a substance that can react with the drugs and products of the current chemical experiment and produce non-toxic or low-toxic products. This is a well-known technology for those skilled in the art, and those skilled in the art need to make a reasonable selection based on the actual situation of the chemical reaction, so it is disclosed in detail in this application.
[0036] Even if the reaction vessel is damaged, it is unlikely to cause leakage of toxic substances, induce safety accidents, or pose risks of dangerous spread.
[0037] A reinforcing net 2 is fixedly connected between the elastic jacket 1 and the inner supporting structure 3. One end of the reinforcing net 2 close to the elastic jacket 1 is embedded in the inner wall of the elastic jacket 1, thereby increasing the structural strength of the elastic jacket 1 and the inner supporting structure 3, so that through cracks appear in the elastic jacket 1 and the inner supporting structure 3. The reinforcing net 2 is woven from a plurality of high-toughness elastic fibers, thereby increasing the structural strength of the woven reinforcing net 2.
[0038] See also Figure 6 The fixing ring 5 includes a hard ring 501, the inner wall of the hard ring 501 contacts the outer wall of the reaction vessel 7, and positions the upper end of the reaction vessel 7, so that the reaction vessel 7 is more stable during the chemical experiment, less likely to shake, and less likely to induce safety accidents. A plurality of disassembly grooves 502 are cut at the upper end of the hard ring 501, and the plurality of disassembly grooves 502 are evenly distributed on the upper side of the hard ring 501, so that the staff can disassemble and replace the disassembly grooves 502 conveniently.
[0039] See also Figure 7A positioner 6 matching the reaction vessel 7 is fixedly connected to the bottom plate of the inner support structure 3. The positioner 6 is made of a water-soluble material. It is worth noting that the positioner 6 in the present application is made of a water-soluble material because water is the solvent for most chemical experiments. When an organic solvent such as ethanol is needed as a solvent for a chemical experiment, the positioner 6, like the support body 301 and the neutralizing liquid, requires professionals in this field to select suitable materials for fixing the lower end of the reaction vessel 7, so that the reaction vessel 7 is more stable during the chemical experiment, less likely to shake, and less likely to induce safety accidents. The positioner 6 includes a plurality of fixing sleeves 601, and the plurality of fixing sleeves 601 are all in a "T" shape. After the chemicals in the reaction vessel 7 leak, the leaked chemical reagents will quickly move the plurality of fixed sleeves 601 to the bottom plate of the inner support structure 3. The corrosion of the fixed sleeve 601 causes the fixation of the lower end of the reaction vessel 7 to be released. At the same time, under the action of the filling balls 303 gushing out of the filling cavity 302, the reaction vessel 7 will be broken and pushed to overturn, and the reaction vessel 7 will fall into the inner support structure 3 as a whole, so that the shrink belt 4 can completely tighten the opening of the elastic jacket 1 and the inner support structure 3. Prefabricated grooves 602 are drilled on multiple fixed sleeves 601, and the prefabricated grooves 602 are located at the end of the fixed sleeve 601 away from the bottom plate of the inner support structure 3, so that the structure of the positioner 6 corroded by chemical reagents can collapse quickly, releasing the positioning of the reaction vessel 7. Multiple prefabricated grooves 602 are all located on the outer wall of the fixed sleeve 601, so that after multiple fixed sleeves 601 are partially corroded, they are easy to tilt in the direction away from the reaction vessel 7, and their own structure is prone to collapse.
[0040] See also Figure 8-10In this solution, the chemical reagent reacts in the reaction container 7. The heat generated by the reaction will cause the temperature of the reaction container 7 to change rapidly. At the same time, the fierce chemical reaction will also impact the reaction container 7, causing fatigue accumulation on the reaction container 7. After the fatigue accumulates to a certain extent, the reaction container 7 will rupture. The debris generated by the rupture will contain a large amount of kinetic energy, which is easy to scratch the inner wall of the support body 301. At the same time, the outflowing chemical reagent will also corrode the support body 301, causing the neutralizing liquid filled in the filling cavity 302 to flow out. During the outflow of the neutralizing liquid, some of the filling balls 303 will flow out together, and the multiple filling balls 303 are partially connected through the filling fibers 304. The spatial structure in the filling cavity 302 will collapse instantly and can no longer play a supporting role. At the same time, the locator 6 will also collapse due to the corrosion line structure of the chemical reagent and can no longer play a positioning role for the reaction container 7. At the same time, under the action of the filling balls 303 pouring out of the filling cavity 302, the reaction container 7 will be broken and pushed to overturn, so that the entire reaction container 7 falls into the inner support structure 3. At this time, under the action of the shrinkage belt 4, the elastic jacket 1, the reinforcement net 2 and the opening of the inner support structure 3 will be tightened to form a cloth bag, complete the sealing, and facilitate subsequent recycling. Even if the reaction container is damaged, it is not easy to cause leakage of toxic substances, induce safety accidents, and have the risk of dangerous diffusion.
[0041] The fixation of the lower end of the reaction container 7 by the positioner 6 makes the reaction container 7 more stable during the chemical experiment, less likely to shake, and less likely to cause safety accidents. After the chemicals in the reaction container 7 leak, the leaked chemical reagents will quickly corrode the multiple fixing sleeves 601, so that the fixation of the lower end of the reaction container 7 is released. At the same time, under the action of the filling balls 303 flowing out of the filling cavity 302, the reaction container 7 will be broken and pushed to overturn. The reaction container 7 falls into the inner support structure 3 as a whole, which makes it easier for the shrink belt 4 to completely tighten the opening of the elastic jacket 1 and the inner support structure 3. The prefabricated grooves 602 excavated on the outside of the multiple fixing sleeves 601 make the multiple fixing sleeves 601 easily tilt away from the reaction container 7 after being partially corroded, and the structure itself is prone to collapse.
[0042] The second implementation method:
[0043] The invention discloses an experimental container for chemical experiments with an alarm structure. A temperature sensor and a pressure sensor are also arranged in a reaction container 7. An alarm device is fixedly connected to the outer wall of an elastic jacket 1. The temperature sensor and the pressure sensor are respectively connected to the alarm device signals. The temperature sensor and the pressure sensor are intelligent sensors, and the alarm device is a buzzer alarm. The structure is simple and reliable. The temperature sensor and the pressure sensor perform simple processing on the detection data while detecting the temperature and pressure in the reaction container 7. When the temperature and pressure in the reaction container 7 detected by the temperature sensor and the pressure sensor change dramatically, the buzzer alarm sounds an alarm to remind researchers that a violent chemical reaction is taking place in the reaction container 7. The researchers need to touch the experimental container less, thereby increasing the safety of the researchers. When the reaction container 7 is damaged and a neutralization reaction occurs, the detection data of the temperature sensor and the pressure sensor will also change dramatically. The buzzer alarm also sounds an alarm to remind researchers to stay away, thereby avoiding irreversible damage to the researchers caused by damage to the elastic jacket 1, thereby increasing the safety of the elastic jacket 1. After the neutralization reaction in the elastic jacket 1 is completed, the temperature and pressure in the elastic jacket 1 return to normal, the buzzer alarm stops working, and the researchers can safely handle the elastic jacket 1.
[0044] Compared with the first embodiment, in this embodiment, through the cooperation of the temperature sensor, the pressure sensor and the buzzer alarm, when a violent chemical reaction occurs or when the reaction container (7) is damaged, the researchers are reminded to touch the experimental container less, thereby increasing the safety of the researchers.
[0045] The above are only preferred specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and improved ideas of the present application, which should be covered by the protection scope of the present application.
