Description

Technical Field

[0001] The invention relates to explosion-proof equipment, in particular to a chemical-proof explosion-proof storage and transportation tank. Background Art

[0002] The explosion-proof tanks of the prior art are mainly used for the storage, transfer and destruction of suspected gunpowder explosives in places such as subways, airports, docks, stations, stadiums, exhibition halls, squares, passenger and cargo ships and railway trains. This explosion-proof tank has a relatively simple structure and does not have a chemical defense function. It is not suitable for the storage, transfer and destruction of biological and chemical explosives at designated locations. Once a biological and chemical explosive explodes in an explosion-proof tank, the toxic and harmful gas (liquid) produced cannot be safely handled. In my country, there are still abandoned ammunition and biological and chemical explosives left over from the war period that need to be stored, transferred and destroyed at designated locations in chemical explosion-proof storage and transportation tanks. So far, there are no literature reports and practical applications of chemical explosion-proof storage and transportation tanks for storage, transfer and destruction of biological and chemical explosives at designated locations.

[0003] The applicant has worked together as a team, and after unremitting research and careful analysis of the existing explosion-proof tanks, the main problems are:

[0004] 1. The sealing and locking of the explosion-proof tank in the prior art usually adopts the method of sealing the mouth of the tank body and the mouth of the tank cover by tightly contacting and sealing, and then locking by a lever device, and the contact surface between the mouth of the tank body and the mouth of the tank cover is a plane. This sealing and locking method is prone to leakage at the contact surface between the mouth of the tank body and the mouth of the tank cover when the explosive explodes. The leakage caused by the explosion of gunpowder explosives is not very harmful, but the leakage caused by the explosion of biological and chemical explosives left over from the war period will cause secondary disasters, endangering people's lives and ecological environment safety;

[0005] 2. The explosion-proof tanks of the prior art are exposed and unprotected inside, and can only meet the temporary storage and transportation needs of suspected explosives such as suspected small-equivalent gunpowder explosions. For abandoned ammunition and biological and chemical explosives left over from the war, the exposed and unprotected explosion-proof tanks cannot meet their temporary storage and transportation needs;

[0006] 3. When using the explosion-proof tank of the prior art, the suspected explosive is directly placed in the tank body and is in a free state in the tank body, which can only meet the temporary storage and transportation needs of suspected explosives such as suspected small-equivalent gunpowder explosions. For the abandoned ammunition and biological and chemical explosives left over from the war period, they are in a free state in the tank body and are very likely to explode accidentally during transportation, causing secondary disasters and endangering people's lives and ecological environment safety;

[0007] 4. The explosion-proof tanks in the prior art are usually placed on the ground or on a transport vehicle through a base. Since the base is in rigid contact with the ground or the transport vehicle, vibration is inevitable during the movement of the explosion-proof tank. For abandoned ammunition and biological and chemical explosives left over from the war, during the transfer and transportation in the explosion-proof tank, the base is in rigid contact with the transport vehicle and vibration is generated, which is very likely to cause accidental explosion, causing secondary disasters and endangering people's lives and ecological environment safety.

[0008] 5. The explosion-proof tanks of the prior art do not have chemical protection functions. Once a biochemical explosive explodes in the explosion-proof tank, the toxic and harmful gases (liquids) produced cannot be safely handled, posing a safety hazard. Summary of the invention

[0030] 2 Its locking ring is simultaneously sleeved on the mouth of the tank body and the mouth of the tank cover, and the structure of simultaneously locking the upper locking device and the lower locking device can ensure that the mouth of the tank body and the mouth of the tank cover are effectively locked, preventing leakage between the mouth of the tank body and the mouth of the tank cover, avoiding secondary disasters, and preventing harm to people's lives and ecological environment safety. The lower arc-shaped part, the left arc-shaped part and the right arc-shaped part of the locking ring form a locking ring, which is sleeved on the mouth of the tank body and the mouth of the tank cover, and can prevent the gap between the tank body and the tank cover from causing leakage; the left arc-shaped part of the locking ring can rotate around the rotating axis to the left, and the right arc-shaped part can rotate around the rotating axis to the right, thereby completing the locking and loosening structure of the tank mouth, the upper locking device of the screw and the nut, and the lower locking device of the lower arc-shaped part of the locking ring supported by the guide plate and the spring can lock and loosen the tank mouth through the mechanical structure of the screw and the nut, further effectively lock the mouth of the tank body and the mouth of the tank cover, and avoid leakage of the tank mouth caused by the impact force of the explosion; the motor and reducer provided can quickly lock and loosen the tank mouth. The push rod assembly provided can use the thrust of the electric push rod to support the locking ring, which further provides a strong guarantee for locking the mouth of the tank body and the mouth of the tank cover;

[0031] 3 Its composite lining protective armor is lined in the chemical explosion-proof storage and transportation tank, which can effectively protect the chemical explosion-proof storage and transportation tank. It adopts a structure of segmented combination of tank body protective armor, tank cover protective armor and tank mouth protective armor, so that it can be used as a vulnerable accessory of the chemical explosion-proof storage and transportation tank, which can not only effectively protect the chemical explosion-proof storage and transportation tank, but also facilitate assembly and installation, and can quickly replace new protective armor after it is damaged; it adopts a double-layer structure of a metal layer and a protective layer, and its metal layer can prevent the waste ammunition or biological and chemical explosives in the tank from penetrating the chemical explosion-proof storage and transportation tank, thereby improving the explosion-proof performance of the chemical explosion-proof storage and transportation tank, and its protective layer can effectively absorb the energy of the waste ammunition or biological and chemical explosives in the tank during the explosion, further increasing the explosion-proof performance of the chemical explosion-proof storage and transportation tank;

The first guide wheel and the second guide wheel change the sliding friction of the telescopic box into rolling friction when the telescopic box moves, reducing the friction force, making the movement of the telescopic box quick and labor-saving. The locking component provided by the self-locking thread simplifies the locking structure and can reliably lock the telescopic box, further improving the stability of the abandoned ammunition or biological and chemical explosives in the tank;

[0034] 6 The decompression and unloading cleaning assembly can first decompress and unload the pressure generated by the explosion of abandoned ammunition in the tank, ensuring that the pressure inside the tank is the same or close to the external pressure, and then open the chemical and explosion-proof storage and transportation tank, avoiding the danger of opening the tank when the pressure inside the tank is much greater than the external pressure, thereby improving the safety of the chemical and explosion-proof storage and transportation tank. Its normal pressure relief unloading pipeline is equipped with a sampling outlet and a sampling valve structure between the pressure relief valve and the normal discharge control valve. Before the pressure relief unloading, the gas and liquid in the tank can be sampled and analyzed to determine whether the gas and liquid in the tank are toxic and harmful. The non-toxic and harmless gas and liquid can be discharged to the outside in an orderly manner, and the toxic and harmful gas and liquid can be discharged into the supporting disinfection system for harmless treatment to avoid secondary disasters. Its emergency unloading pipeline can replace the normal pressure relief unloading pipeline for pressure relief unloading when the normal pressure relief unloading pipeline fails. Its cleaning component can clean the chemical defense and explosion-proof storage and transportation tank to avoid secondary disasters caused by the toxic and harmful gases and liquids remaining after the chemical defense and explosion-proof storage and transportation tank handles biochemical explosives, thereby endangering people's lives and the ecological environment.

[0035] It has the advantages of reasonable structure, low cost, flexible operation, reliable locking, rapid sealing and good effect, stable position and small vibration, simple and easy to manufacture, and good protection effect. BRIEF DESCRIPTION OF THE DRAWINGS
