An emergency leak-proof hazardous chemical transport tank

Abstract

This utility model relates to the field of hazardous chemical transportation equipment technology, and in particular to an emergency leak-proof hazardous chemical transportation tank, including a tank body, a tank cover, and several baffles vertically arranged in the inner cavity of the tank. The baffles have a hyperboloid arc structure, with one side being an outwardly convex curved surface and the other side being an inwardly concave curved surface. The inwardly concave curved surface is integrally formed with reinforcing ribs. By using the hyperboloid arc structure of the baffles, the outwardly convex curved surface can directly bear the surge impact of the medium inside the tank. The guiding effect of the arc curved surface disperses the impact force, reducing the problem in the prior art where the reaction force caused by the concentrated impact force is directly transmitted to the tank wall. At the same time, the inwardly concave curved surface and the integrally formed reinforcing ribs form several buffer zones, which can further achieve buffering and reduce leakage hazards such as cracks and perforations, adapting to the complex road conditions of frequent vehicle starts, stops, and lane changes during emergency transfer.

Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical transportation equipment technology, and in particular to an emergency leak-proof hazardous chemical transportation tank. Background Technology

[0002] Hazardous chemical storage tanks are one of the core pieces of equipment for emergency response to chemical accidents and emergency transfer of hazardous chemicals. In sudden emergency scenarios such as leaks and explosions, it is necessary to quickly complete the temporary storage and transfer of hazardous chemicals, which places stringent requirements on the impact resistance and leak prevention performance of the tank. During emergency transfer, vehicles need to frequently start and stop and change lanes to cope with complex road conditions, and the medium inside the tank will generate violent surge impacts. Although current transport tanks are equipped with baffles, the existing baffles are all flat structures. When the vehicle starts, stops, or brakes suddenly, the medium inside the tank directly impacts the surface of the baffle. Since the flat structure cannot effectively disperse the impact force, the reaction force generated by the impact will be directly transmitted to the tank wall. Under long-term repeated action, the metal fatigue damage of the tank wall will be aggravated, and cracks or even perforations will easily appear, causing hazardous chemical leaks.

[0003] Therefore, based on the above situation, we propose an emergency leak-proof hazardous chemical transport tank to solve the above problems. Utility Model Content

[0004] This invention provides an emergency leak-proof hazardous chemical transport tank to solve the problems existing in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: An emergency leak-proof hazardous chemical transport tank includes a tank body, a tank cover, and several baffles vertically arranged in the inner cavity of the tank. The baffles have a hyperboloid arc structure, with one side being an outwardly convex curved surface and the other side being an inwardly concave curved surface. Reinforcing ribs are integrally formed on the inwardly concave curved surface, and the reinforcing ribs and the inwardly concave curved surface enclose several buffer zones. A flow-through component is provided through the baffle.

[0006] Preferably, the reinforcing rib unit includes multiple main reinforcing ribs and multiple secondary reinforcing ribs. The main reinforcing ribs are distributed crisscrossingly along the inner wall of the tank, and the secondary reinforcing ribs are evenly distributed within the enclosed area of ​​adjacent main reinforcing ribs.

[0007] Preferably, the thickness of the main reinforcing rib is greater than the thickness of the secondary reinforcing rib.

[0008] Preferably, the flow component includes a first flow hole at the bottom of the wave deflector and a second flow hole at the top of the wave deflector, with the second flow holes on the wave deflector being staggered.

[0009] Preferably, the diameters of the first flow hole and the second flow hole gradually increase along the direction from the convex surface of the wave deflector to the concave surface.

[0010] Preferably, the diameter of the second flow hole is larger than the diameter of the first flow hole.

[0011] The beneficial effects of this utility model are as follows: by using a wave deflector with a hyperboloid arc structure, its convex curved surface can directly bear the surge impact of the medium inside the tank. The guiding effect of the arc curved surface disperses the impact force, reducing the problem in the prior art where the reaction force is directly transmitted to the tank wall due to the concentration of impact force. At the same time, the concave curved surface and the integrated molded reinforcing rib unit form several buffer zones, which can further achieve buffering and reduce leakage hazards such as cracks and perforations, and adapt to the complex road conditions of frequent vehicle starts, stops and lane changes during emergency transfer.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] Reference Figures 1-5As shown, an emergency leak-proof hazardous chemical transport tank includes a tank body 1, a tank cover 2, and several baffles 3 vertically arranged inside the tank body 1. The tank body 1 is generally made of stainless steel in one piece to ensure that the tank body 1 has sufficient structural strength to adapt to the high-frequency impact scenario of emergency transfer of hazardous chemicals. The tank cover 2 can be detachably connected to the flange interface at the top of the tank body 1 by locking bolts evenly distributed around the circumference. In actual use, a fluororubber sealing gasket is embedded between the tank cover 2 and the flange interface to effectively prevent hazardous chemicals from leaking from the connection between the tank cover 2 and the tank body 1. The baffles 3 are vertically arranged at equal intervals along the length of the inner cavity of the tank body 1. The outer diameter of the baffles 3 is adapted to the inner diameter of the tank body 1, and its edge can be fixed to the inner wall of the tank body 1 by high-strength fastening bolts. To improve the wave-damping effect, the wave deflector 3 has a hyperboloid arc structure. Its convex surface faces the rear of the tank 1, and its concave surface faces the front of the tank 1. The curvature of the concave surface matches the curvature of the convex surface. A flow-through component 5 is provided through the wave deflector 3. When the tank cover 2 is opened to transport the medium into the tank 1, the medium will pass through the wave deflector 3 through the flow-through component 5 and be evenly distributed inside the tank 1. When filling the tank, the medium can quickly pass through each layer of wave deflectors 3 with the help of the flow-through component 5, avoiding local accumulation due to the obstruction of the wave deflectors 3. This makes the distribution of the medium in the tank more even, reducing the shift of the center of gravity of the tank 1 caused by the uneven loading of the medium during loading and unloading, and improving the safety of loading and unloading operations. During emergency transfer, when the vehicle frequently starts, stops, and brakes suddenly, the medium in the tank will first surge backward. This backward surge of medium will directly impact the concave surface of the rear wave deflector 3. This concave surface acts like a buffer, dispersing the backward impact force and preventing the medium from colliding at the rear. Then, due to inertia, the medium surges forward, and this forward impact force strikes the convex curved surface of the front baffle 3. The arc-shaped convex surface guides the medium along the curved surface, preventing the impact force from concentrating directly in one area. Furthermore, multiple baffles 3 divide the inner cavity of the tank 1 into several small areas, each containing a small amount of medium, thus reducing the impact force from the source. The integrally formed reinforcing rib unit 4 on the concave curved surface enhances the structural strength of the baffle 3, preventing deformation and cracking when repeatedly subjected to media impacts, further ensuring the stability of the buffering effect. Therefore, regardless of whether the medium surges backward or forward, the impact force is weakened layer by layer and does not concentrate on the tank wall, thereby reducing the risk of tank wall damage and leakage.

[0017] Reference Figure 5As shown, further, the reinforcing rib unit 4 includes multiple main reinforcing ribs 41 and multiple secondary reinforcing ribs 42. The main reinforcing ribs 41 are distributed crisscrossingly along the inner wall of the tank body 1, and the length of each main reinforcing rib 41 is consistent with the diameter of the baffle plate 3. The secondary reinforcing ribs 42 are evenly distributed in the enclosed area of ​​adjacent main reinforcing ribs 41, forming a grid with the main reinforcing ribs 41. The main reinforcing ribs 41 can form the core support frame of the baffle plate 3, resisting the main stress generated by the impact of the medium. The secondary reinforcing ribs 42 assist in strengthening the local structure and dispersing the stress between the main reinforcing ribs 41. Moreover, the thickness of the main reinforcing ribs 41 is greater than the thickness of the secondary reinforcing ribs 42. Ribs 41 are distributed in a cross pattern along the inner wall of the tank body 1. They are the core load-bearing skeleton of the baffle plate 3 and need to directly bear the main impact force generated by the medium. A thicker rib can improve its resistance to bending and deformation, and prevent the baffle plate 3 from collapsing or cracking under high-frequency impact. The secondary reinforcing ribs 42 only need to help disperse the local stress between the main reinforcing ribs 41. They are thinner than the main reinforcing ribs 41, which is sufficient to meet the requirements and reduce structural redundancy. Through the core support of the main reinforcing ribs 41 and the auxiliary reinforcement of the secondary reinforcing ribs 42, the stress of the baffle plate 3 can be evenly distributed to the entire concave curved surface when it is subjected to the impact of the medium, avoiding structural damage caused by local stress concentration.

[0018] Reference Figure 5 As shown, furthermore, a flow component 5 is provided through the baffle plate 3. The flow component 5 includes a first flow hole 51 located at the bottom of the baffle plate 3 and a second flow hole 52 located at the top of the baffle plate 3. The first flow hole 51 is located at the bottom edge of the baffle plate 3, which can ensure the normal flow of the medium at the bottom of the tank and prevent the medium from stagnating and accumulating at the bottom of the tank for a long time. The second flow hole 52 is located in the upper area of ​​the baffle plate 3, away from the bottom of the tank, and is used to guide the flow of the upper medium. The second flow holes 52 on multiple baffle plates 3 are staggered, and the second flow holes 52 on two adjacent baffle plates 3 are not on the same straight line, which forces the surge medium to change the flow direction when passing through each layer of baffle plates 3, and avoids the impact force to be superimposed and transmitted along a straight line, thereby further improving the anti-surge effect.

[0019] Both the first flow hole 51 and the second flow hole 52 are variable diameter holes. The diameter of both gradually increases along the direction from the convex surface of the baffle plate 3 to the concave surface. When the medium impacts the convex surface of the baffle plate 3, it will first enter the small diameter end of the flow hole, and then flow to the buffer zone on the concave surface side through the channel with gradually increasing diameter. This gradual diameter design can buffer and guide the flowing medium, avoid the medium from turbulent impact caused by the sudden change in the flow cross section at the orifice, reduce stress concentration at the edge of the orifice, reduce cracking and damage of the flow hole due to long-term impact, and ensure the stability of the medium flow.

[0020] Reference Figure 5As shown, the diameter of the second flow hole 52 is larger than that of the first flow hole 51. The larger diameter of the second flow hole 52 can quickly divert the surging medium in the upper layer, allowing the medium to enter the buffer zone in time to dissipate energy and improve the buffering effect on the upper surge. Meanwhile, the lower medium is relatively stable, and the smaller diameter of the first flow hole 51 can prevent the lower medium from violently surging due to excessive flow, ensuring the efficient diversion and buffering of the upper surge medium, while also constraining the flow state of the lower medium, thereby improving the flow efficiency of the medium in the entire tank 1 and meeting the requirements for buffering and wave protection.
