Description

Technical Field

[0001] The invention relates to the technical field of safe transportation of thiazole solution filling machines, and in particular to a filling container structure for realizing rapid filling and safe transfer and transportation of pure thiazole solution in a workshop, in particular to an explosion-proof and leak-proof filling container for pure thiazole solution. Background Art

[0002] The chemical formula of thiazole is C3H3NS. Thiazole is a five-membered heterocyclic compound containing one sulfur and one nitrogen atom. Thiazole and isothiazole do not exist in nature and are generally produced by industrial synthesis.

[0003] At the same time, thiazole can also be used as an organic synthesis reagent for the synthesis of drugs, dyes, rubber accelerators, film coloring, fungicides and dyes, etc.

[0004] Thiazole in its natural state is a light yellow liquid with a corrupt odor, a boiling point of 116.8°C, and a relative density of 1.998 (17 / 4°C). It is harmful to the body if inhaled, ingested, or absorbed through the skin, and is irritating to the eyes and skin.

[0005] The traditional method for synthesizing thiazoles mainly adopts a multi-step synthesis method, which realizes the synthesis through the transformation between functional groups; with the development of green chemistry, the existing technology begins to adopt a one-step method to synthesize thiazole compounds.

[0006] After the preparation of pure thiazole in industrial chemical workshops, it is necessary to fill and hold it in sealed containers. Since pure thiazole has high dangerous characteristics, such as being flammable, toxic, and irritating, it is at risk of combustion and explosion when exposed to open flames, high heat, or contact with oxidants. Therefore, currently, when packaging pure thiazole, it is mainly sealed and held in rigid sealed containers with sealed screw caps. After the filling in the workshop, the pure thiazole containers need to be transported to the hands of downstream distributors or customers in need by transfer vehicles or transportation equipment.

[0007] There are also some technologies for preserving pure thiazole in the prior art. For example, a patent document with patent application number CN201611233091.9 also discloses a safe storage method for thiazole, which mainly includes the following steps: ①, collect or newly configure thiazole, the collected thiazole should not exceed 5h, and the thiazole must be pure and free of other impurities; ②, preliminarily clean the collected thiazole, place it in multiple containers respectively, and then place the containers in a cold storage, and adjust the temperature in the cold storage to 2-5°C; ③, adjust the humidity in the cold storage to 20-30%, and then adjust the carbon dioxide content to 24-35%; ④, fill the container filled with thiazole with Clean water, the clean water should be 3-5cm higher than the thiazole liquid level, then shake it slightly and let it stand; ⑤, take a sealed jar, the sealed jar is a glass jar with brown glass, and a layer of quicklime is laid on the bottom of the sealed jar, and then a layer of soft cloth is laid on the quicklime, and then the above containers are placed in a group of 6-8 in the sealed jar and sealed; ⑥, adjust the air humidity in the above sealed jar to 25-30%, and then evacuate it to vacuum, cover it and seal it, and use wax oil to seal the mouth of the sealed jar; ⑦, check the temperature and humidity in the cold storage and the air humidity in the sealed jar every week, and check the vacuum degree in the sealed jar and the clean water content in the container until it is taken out for use.

[0008] From the above, it can be seen that the above patent mainly utilizes a sealed tank structure to store pure thiazole. However, the current situation is that when encountering complex road conditions with bumps during long-distance transportation, it is easy to cause the temperature and explosion inside the pure thiazole due to excessive shock, which poses a great safety hazard. Obviously, the storage method and container in the prior art cannot meet the use requirements under transportation conditions.

[0009] In addition, after the pure thiazole container is transported to the place of use, since the existing containers mainly adopt the traditional sealed screw cap and sealed container structure, when the pure thiazole in the sealed container with a larger capacity is released for use, it is generally necessary to remove the sealed screw cap, which can easily cause the pure thiazole to spill and also easily cause contamination of the pure product inside.

[0010] To this end, the present invention has developed a filling container structure for pure thiazole that can achieve stable transportation and safe reloading, so as to better solve the problems existing in the prior art. Summary of the invention

[0082] The annular shock-absorbing pad 24 can ensure the purpose of shock absorption and buffering when the container monomers 1 are stacked, ensure the safety and stability of the stacked units during transportation, and reduce the situation of excessive hard collisions between adjacent container monomers 1.

[0083] Specific working principle:

[0084] Each container unit 1 of the explosion-proof and leak-proof filling container of pure thiazole solution can be used separately as a separate and independent sealed container. At the same time, when loading on a transport vehicle, multiple container units 1 can be stacked up and down in sequence, and the stacking stability between adjacent container units 1 can be ensured after stacking, so as to ensure that it can cope with various bumpy road conditions in the transportation state. In addition, when the transportation reaches the use environment, the internal pure thiazole solution can be quickly and quantitatively discharged from the discharge valve 5 according to the use requirements to meet the use requirements, and it can be quickly closed after discharging.

[0085] During filling, the feed one-way valve 19 can serve the purpose of liquid inlet conduction and reverse sealing. The pure thiazole solution entering through the feed one-way valve 19 can be quickly injected into the cylindrical barrel 2 through the liquid inlet guide hole 11. At the same time, when the injection amount reaches the set amount, the buoyancy plugger will be lifted up, thereby enabling it to block the two liquid inlet guide holes 11.

[0086] In summary, the overall safety and sealing performance of the container is good, and it can be used for the rapid filling of pure thiazole solution. After filling, the container can be effectively sealed; the individual container monomers 1 inside the container can be effectively stacked, and the stability after stacking is good, and the sealing effect of each container monomer 1 can be effectively guaranteed during transportation; when feeding and pouring, due to the existence of a quantitative anti-overflow mechanism, the maximum injection volume inside can be effectively controlled, and when the maximum volume is reached, automatic blocking can be effectively achieved to prevent feeding; a safety buffer space D is reserved between the quantitative anti-overflow mechanism and the one-way injection assembly B, which can better In response to the internal high pressure under a certain state, the quantitative overflow prevention mechanism is lifted to achieve expansion and pressure reduction, so as to achieve safe pressure reduction and prevent the occurrence of excessive internal pressure, thereby achieving the purpose of preliminary control of safety; when the internal pressure increases significantly during transportation or collision, the quantitative overflow prevention mechanism is passively lifted to the highest position to achieve passive operation of the safety and explosion-proof components, at which time the upper film layer 21 will be punctured. After the film layer 21 is punctured, the water inside the water storage tank 20 will quickly fall into the through cavity 7 and continue to fall to mix with the pure thiazole solution inside the cylindrical barrel 2 to achieve cooling and explosion prevention, thereby further achieving the purpose of safety and explosion prevention.
