Description

Technical Field

[0001] This utility model relates to the field of chemical product transportation technology, and in particular to an explosion-proof storage device for transporting chemical products. Background Technology

[0002] Due to their high volatility, flammability, and explosiveness, chemical products require stringent sealing and explosion-proof performance from their containers during transportation and storage. This is especially true in the chemical transportation sector, where leaks of raw materials such as etching solutions and developers during transport, or exposure to external environmental factors, can easily trigger explosions, threatening personnel safety and the production environment. Therefore, developing a storage device that combines multiple sealing features with efficient buffering has become a key technological requirement for improving the safety of chemical transportation.

[0003] In existing technologies, chemical product storage devices mostly employ a single sealing structure. For example, the tank is sealed using rubber gaskets and bolts, while relying on an external metal shell for basic protection. Common shock-absorbing designs include placing springs or foam materials between the tank and the outer shell to absorb vibration energy during transportation. These structures, through rigid connections or simple elastic elements, mitigate the direct impact of shock forces on the tank to some extent.

[0004] However, the aforementioned traditional sealing methods have significant drawbacks. Due to continuous vibration and impact during transportation, a single sealing structure is prone to seal failure due to loose bolts or aging rubber gaskets, resulting in leakage of chemical products. Once the volatile chemicals mix with air, they may cause an explosion if they encounter static electricity or high temperature environments. Existing technologies have not completely solved the dynamic sealing problem under vibration environments, which limits the safety of chemical product transportation. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an explosion-proof storage device for transporting chemical products, aiming to improve the problem that the single sealing structure is prone to sealing failure due to loose bolts or aging rubber gaskets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof storage device for transporting chemical products, comprising a tank, wherein a sealing assembly is provided inside the tank, a shell is fitted outside the tank, a connecting block is fixedly connected to the outer wall of the tank, and a buffer assembly is provided inside the connecting block;

[0007] The sealing assembly includes a sealing cap disposed inside the tank body. A threaded rod is rotatably connected inside the sealing cap. A threaded tube is threadedly connected to the outer wall of the threaded rod. A connecting ring is fixedly connected to the outer wall of the threaded tube. A sealing gasket is fixedly connected to the lower surface of the connecting ring. A transmission rod is slidably connected inside the sealing cap. A ball is fixedly connected to one end of the transmission rod. A groove is formed on the inner wall of the tank body.

[0008] Furthermore, the buffer assembly includes a locking block, the outer wall of which is slidably connected to the inner wall of the connecting block. A hinge seat one is fixedly connected to one side of the outer wall of the locking block. An inner rod is rotatably connected inside the hinge seat one. An outer tube is slidably connected to the outer wall of the inner rod. An annular groove is formed inside the outer tube. A hinge seat two is rotatably connected to one end of the outer tube. The outer wall of the hinge seat two is fixedly connected to the inner wall of the housing. Damping fluid is provided inside the annular groove.

[0009] Furthermore, a second spring is sleeved on the outer wall of the inner rod, with one end of the second spring fixedly connected to the outer wall of the inner rod and the other end of the second spring fixedly connected to the upper surface of the outer tube.

[0010] Furthermore, a spring is provided inside the housing, and a soft pad is provided inside the housing.

[0011] Furthermore, one end of the spring is fixedly connected to the lower surface of the inner wall of the housing, and the other end of the spring is fixedly connected to the lower surface of the soft pad.

[0012] Furthermore, a spring is provided inside the sealing cover, with one end of the spring fixedly connected to one side of the limiting ring and the other end of the spring fixedly connected inside the sealing cover.

[0013] Furthermore, a handwheel is fixedly connected to one end of the threaded rod, and the connecting ring is disposed on the upper surface of the tank.

[0014] Furthermore, the soft pad is disposed on the lower surface of the can body, and the ball bearing is disposed inside the groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the sealing cap, threaded rod, threaded tube and sealing gasket in the sealing assembly work together to achieve multiple seals on the tank. Rotating the handwheel drives the threaded rod to rotate, so that the threaded tube drives the connecting ring and sealing gasket to fit tightly against the tank opening. Combined with the guide and locking of the transmission rod, ball and groove, it effectively prevents chemical product leakage and significantly reduces the risk of explosion caused by volatilization or external environment.

[0017] 2. In this utility model, the buffer assembly forms a multi-stage energy dissipation mechanism through the elastic cooperation of the hinge seat, inner rod, outer tube and spring two, combined with the damping fluid filled inside the outer tube. During transportation, the relative movement of the inner rod and the outer tube forces the damping fluid to generate viscous resistance, converting the impact kinetic energy into heat energy. At the same time, the elastic deformation of spring two and the flow characteristics of the damping fluid work together to effectively suppress the vibration amplitude and reduce the impact rebound, further enhancing the explosion-proof safety and transportation stability.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of an explosion-proof storage device for transporting chemical products, comprising a tank 1, a sealing assembly inside the tank 1, and a shell 13 covering the outside of the tank 1. A connecting block 14 is fixedly connected to the outer wall of the tank 1, and a buffer assembly is installed inside the connecting block 14. The double-layer structure design of the tank 1 and the shell 13 not only provides physical protection but also achieves dynamic shock absorption through the buffer assembly inside the connecting block 14, significantly improving the ability to disperse impact energy during transportation. The sealing assembly includes a sealing cap 3, which is disposed inside the tank 1. A threaded rod 4 is rotatably connected inside the sealing cap 3. A threaded tube 6 is threadedly connected to the outer wall of the threaded rod 4. A connecting ring 7 is fixedly connected to the outer wall of the threaded tube 6, and a sealing gasket 8 is fixedly connected to the lower surface of the connecting ring 7. Rotating a handwheel 5 drives the threaded rod 4 to rotate, which in turn drives the threaded tube 6 to move axially through the threaded pair, pushing the connecting ring 7 and the sealing gasket 8 to tightly fit against the opening of the tank 1. A rigid sealing layer is formed to effectively block the evaporation path of chemical substances. A transmission rod 9 is slidably connected inside the sealing cap 3, and a ball bearing 10 is fixedly connected to one end of the transmission rod 9. A groove 2 is opened on the inner wall of the tank body 1. The linkage design of the transmission rod 9 and the ball bearing 10 allows the ball bearing 10 to be embedded in the groove 2. The position of the sealing cap 3 is fixed by a mechanical locking mechanism, which can prevent the sealing gasket 8 from shifting even under severe vibration, ensuring sealing stability. A spring 12 is set inside the sealing cap 3. One end of the spring 12 is fixedly connected to one side of the limiting ring 11, and the other end of the spring 12 is fixedly connected to the inside of the sealing cap 3. A handwheel 5 is fixedly connected to one end of the threaded rod 4. The connecting ring 7 is set on the upper surface of the tank body 1, and the ball bearing 10 is set inside the groove 2. The handwheel 5 simplifies the complexity of the sealing operation. The operator can quickly complete the sealing and locking by rotating the handwheel 5. At the same time, the cooperation between the ball bearing 10 and the groove 2 achieves tool-free precise positioning, which greatly improves the operating efficiency.

[0027] Reference Figures 1-5The buffer assembly includes a locking block 15, the outer wall of which is slidably connected to the inner wall of a connecting block 14. A hinge seat 16 is fixedly connected to one side of the outer wall of the locking block 15. An inner rod 17 is rotatably connected inside the hinge seat 16. An outer tube 19 is slidably connected to the outer wall of the inner rod 17. The sliding engagement between the locking block 15 and the connecting block 14 allows the buffer assembly to freely adjust its angle in three-dimensional space. The relative movement between the inner rod 17 and the outer tube 19 can absorb impact forces from different directions, improving the adaptability of the device. An annular groove 20 is provided inside the outer tube 19. A hinge seat 21 is rotatably connected to one end of the outer tube 19. The outer wall of the hinge seat 21 is fixedly connected to the inner wall of the shell 13. Damping fluid is provided inside the annular groove 20. When the inner rod 17 and the outer tube 19 move relative to each other, viscous resistance is generated, which converts the impact kinetic energy into heat energy dissipation, significantly reducing the vibration transmission to the tank 1. The inner rod 17 is fitted with a second spring 18 on its outer wall. One end of the second spring 18 is fixedly connected to the outer wall of the inner rod 17, and the other end is fixedly connected to the upper surface of the outer tube 19. The second spring 18 absorbs the impact energy when compressed and counteracts the rebound effect through elastic restoring force. It works in synergy with the viscous resistance of the damping fluid to form a multi-stage buffer mechanism, extending the impact attenuation time. A third spring 22 is installed inside the shell 13, and a soft pad 23 is installed inside the shell 13. One end of the third spring 22 is fixedly connected to the lower surface of the inner wall of the shell 13, and the other end is fixedly connected to the lower surface of the soft pad 23. The soft pad 23 is set on the lower surface of the tank 1. The combined design of the third spring 22 and the soft pad 23 absorbs the vertical impact between the tank 1 and the shell 13 through elastic deformation. The high damping material of the soft pad 23 further reduces local stress concentration and prevents the bottom of the tank 1 from deforming due to collision.

[0028] Working principle: When this explosion-proof chemical product transport and storage device is needed, first rotate the handwheel 5 to drive the threaded rod 4 to rotate. The threaded rod 4 and the threaded tube 6 are connected by threads, driving the threaded tube 6 to move axially, thereby pushing the connecting ring 7 and the sealing gasket 8 downward, so that the sealing gasket 8 tightly fits the opening of the tank body 1, forming the first seal. At the same time, the transmission rod 9 slides inside the sealing cover 3, and the limiting ring 11 connected to the outside of the transmission rod 9 compresses the spring 12 inside the sealing cover 3. The ball bearing 10 at its end is embedded in the groove 2 on the inner wall of the tank body 1, locking the position of the sealing cover 3 and preventing the seal from failing due to vibration, thus completing multiple sealing protections. When transporting, first put the tank... The body 1 is placed into the shell 13, so that the locking block 15 is installed in the connecting block 14. If an external impact or vibration is transmitted to the shell 13, the buffer assembly starts to work. The power is transmitted from the hinge seat 21 to the outer tube 19, which drives the inner rod 17 and the hinge seat 16 to move. The inner rod 17 and the outer tube 19 are relatively displaced, which forces the damping fluid filled in the annular groove 20 inside the outer tube 19 to generate viscous resistance, converting the impact kinetic energy into heat energy for dissipation. At the same time, the second spring 18 is elastically compressed between the inner rod 17 and the outer tube 19, further absorbing the vibration energy. The third spring 22 and the soft pad 23 inside the shell 13 work together to reduce the direct collision between the tank 1 and the shell 13 through elastic deformation, thereby reducing local stress.
