Description

Technical Field

[0001] The present invention relates to the field of storage and transportation of chemical raw materials, and particularly to a storage device for transporting chemical raw materials. Background Art

[0002] The storage barrels used for transporting chemical raw materials need to have high-performance shock-absorbing bases to reduce the vibration impact on chemical raw materials during transportation. Therefore, the existing storage barrels for transporting chemical raw materials can simply achieve the effect of weakening the vibration impact on chemical raw materials by adding a shock-absorbing and energy-absorbing mechanism to the base. However, when multiple storage barrels for transporting chemical raw materials with shock-absorbing and energy-absorbing mechanisms are placed vertically stacked in a transportation carriage, since there are multiple shock-absorbing and energy-absorbing mechanisms between each vertically stacked group of storage barrels, this will cause the storage barrel for transporting chemical raw materials at the top layer to be subjected to the shock-absorbing effect of the up-and-down swinging of the multiple shock-absorbing and energy-absorbing mechanisms below, resulting in an increase in the up-and-down movement stroke of the storage barrel for transporting chemical raw materials at the top layer during the shock-absorbing process, thereby leading to the potential danger of unstable stacking due to an excessive swinging range of the storage barrel for transporting chemical raw materials at the top layer. Especially when the transportation carriage is driving in a sharp-turn area, the vertically stacked group of storage barrels will be subjected to a large roll shock, and at this time, the storage barrel for transporting chemical raw materials at the top layer is in danger of tipping over and collapsing. Summary of the Invention

[0003] In order to overcome the drawback that when multiple storage barrels for transporting chemical raw materials with shock-absorbing and energy-absorbing mechanisms are vertically stacked in a transportation carriage, the storage barrel for transporting chemical raw materials at the top layer is in danger of tipping over and collapsing, the present invention provides a storage device for transporting chemical raw materials.

[0019] As Figure 2 and Figure 3As shown in the figure, the height-adjusting component includes a height-adjusting lead screw 231, a spur gear 232, and a spur gear ring 233; several height-adjusting lead screws 231 are rotatably connected to the upper sliding ring 21; each height-adjusting lead screw 231 is screwed to the upper annular frame 24 through its own thread structure; a spur gear 232 is fixedly connected to each height-adjusting lead screw 231; a spur gear ring 233 is rotatably connected to the upper sliding ring 21; the outer surface of the spur gear ring 233 is provided with an anti-slip stripe structure; each spur gear 232 meshes with the spur gear ring 233.

[0020] As Figure 8 As shown in the figure, after stacking multiple storage devices for transporting chemical raw materials of the present invention up and down, a base 3 is provided below the lower annular frame 27 of the storage device for transporting chemical raw materials of the present invention at the bottom layer; socket structures 301 corresponding to the number and positions of the insertion rod structures 271 of the lower annular frame 27 are provided on the base 3; all the insertion rod structures 271 of the lower annular frame 27 are respectively inserted into the corresponding socket structures 301 on the base 3; a damping spring telescopic rod 31 is fixedly connected to each socket structure 301 of the base 3; the bottom of the insertion rod structure 271 of the lower annular frame 27 closely abuts against the damping spring telescopic rod 31 in the corresponding socket structure 301; a reset compression spring 32 is fixedly connected between the base 3 and the lower annular frame 27.

[0021] The following are the storage preparation work steps of the storage device for transporting chemical raw materials of the present invention.

[0022] First, the staff opens the top cover 12 on the storage barrel 11, pours the chemical raw material into the interior of the storage barrel 11, and controls the liquid level height of the chemical raw material to be below the first anti-surge plate structure 111 on the upper side. Then, the top cover 12 is covered back between the storage barrel 11 and the first anti-surge plate structure 111 on the upper side. After the staff opens the exhaust valve 14, they then hold the carried protective gas delivery device and deliver the protective gas to the gas inlet valve 13. The protective gas flows through the bottom gas delivery channel structure 1301 of the gas inlet valve 13 and the bottom gas outlet channel structure 1201 of the top cover 12 in sequence and is injected into the interior of the storage barrel 11. At the same time, the protective gas injected into the interior of the storage barrel 11 will squeeze out the original air inside the storage barrel 11 through the exhaust valve 14, and the residual air inside the storage barrel 11 is replaced by the protective gas. The protective gas can provide fire and explosion protection for the chemical raw material in the storage barrel 11.

[0023] Subsequently, the staff closes the exhaust valve 14, and then rotates the gas transmission valve 13 until the side gas transmission channel structure 1302 of the gas transmission valve 13 is connected to the side gas outlet channel structure 1202 of the top cover 12. Then, the staff holds the carried protective gas delivery device and delivers protective gas to the gas transmission valve 13. The protective gas successively flows through the side gas transmission channel structure 1302 of the gas transmission valve 13 and the side gas outlet channel structure 1202 of the top cover 12 and enters each two-way gas transmission channel structure 1101 of the storage barrel 11 respectively. The protective gas is then injected into the upper annular airbag 22 and the lower annular airbag 26 respectively, so that the upper annular airbag 22 and the lower annular airbag 26 filled with pressurized protective gas respectively push the upper sliding ring 21 and the lower sliding ring 25 to drive the connected upper annular frame 24 and lower annular frame 27 to move away from each other in the up and down directions. At the same time, the lower annular frame 27 in contact with the ground supports the entire storage barrel 11 upward through the inflated lower annular airbag 26, realizing that the upper annular airbag 22 and the lower annular airbag 26 respectively expand and support the upper annular frame 24 and the lower annular frame 27 at different heights in the up and down directions. After that, the staff rotates the gas transmission valve 13 again to make the gas transmission valve 13 no longer in a connected state with the top cover 12.

[0024] Finally, the staff closes and puts away the carried protective gas delivery device. At this time, the upper annular airbag 22 and the lower annular airbag 26 respectively maintain the state of expanding and supporting the upper annular frame 24 and the lower annular frame 27 away from the storage barrel 11, making the storage barrel 11 in an independent suspended state. The upper annular airbag 22 and the lower annular airbag 26 filled with pressurized protective gas provide anti-impact buffer protection for the storage barrel 11 in the form of air springs, completing the storage preparation work of a storage device for transporting chemical raw materials of the present invention.

[0025] The following are the stacking and transportation working steps of a storage device for transporting chemical raw materials of the present invention.

[0026] First, the staff places a base 3 in the transportation carriage. Then, the staff stacks multiple storage devices for transporting chemical raw materials of the present invention that have completed the storage preparation work vertically above the base 3. At this time, the bottom of the insertion rod structure 271 of the lower annular frame 27 in the storage device for transporting chemical raw materials of the present invention at the bottom layer presses downward tightly against the damping spring telescopic rod 31 in the corresponding socket structure 301, causing the damping spring telescopic rod 31 and the return compression spring 32 to be compressed downward by the weight pressure of all the storage devices for transporting chemical raw materials of the present invention above. The compressed damping spring telescopic rod 31 and return compression spring 32 jointly absorb the vibration impact received by all the storage devices for transporting chemical raw materials of the present invention above. Then, the staff rotates the straight tooth rings 233 of each storage device for transporting chemical raw materials of the present invention in turn. The straight tooth ring 233 meshes with the connected straight gear 232 to drive the height-adjusting screw rod 231 to rotate. The height-adjusting screw rod 231 pushes the corresponding upper annular frame 24 upward to increase the upward expansion distance of the upper annular frame 24 until the upper annular frame 24 of the storage device for transporting chemical raw materials of the present invention at the top layer can tightly adhere to the inner top of the transportation carriage, firmly supporting the top of the stacked storage devices for transporting chemical raw materials of the present invention in the inner top of the transportation carriage and forming a support column structure that expands in the vertical direction of the transportation carriage. At this time, even if the transportation carriage experiences a severe rollover, the stacked storage devices for transporting chemical raw materials of the present invention in the transportation carriage will not easily tip over or collapse.

[0027] In addition, when the staff adjusts the height-adjusting screw rods 231 of all the storage devices for transporting chemical raw materials of the present invention to raise each upper annular frame 24 to the highest position, if the upper annular frame 24 of the storage device for transporting chemical raw materials of the present invention at the top layer still cannot tightly adhere to the inner top of the transportation carriage, the staff can first inject more pressurized protective gas into the upper annular airbag 22 and the lower annular airbag 26 of the storage device for transporting chemical raw materials of the present invention at the bottom layer. The more pressurized protective gas is injected into the upper annular airbag 22 and the lower annular airbag 26, the higher the upper annular airbag 22 and the lower annular airbag 26 expand and support the upper annular frame 24 and the lower annular frame 27 respectively, and the stronger the load-bearing capacity of the upper annular airbag 22 and the lower annular airbag 26. By adjusting the injection amount of the pressurized protective gas in the upper annular airbag 22 and the lower annular airbag 26, the height of the upper annular frame 24 can also be adjusted until the upper annular frame 24 of the storage device for transporting chemical raw materials of the present invention at the top layer can tightly adhere to the inner top of the transportation carriage.

[0028] Embodiment 2 Based on Embodiment 1, as Figures 1-7As shown in the figure, an upper annular guard plate 28 is fixedly connected to the upper sliding ring 21 of this embodiment; the upper annular guard plate 28 surrounds the outside of the upper annular airbag 22; a lower annular guard plate 29 is fixedly connected to the lower sliding ring 25; the lower annular guard plate 29 surrounds the outside of the lower annular airbag 26; both the upper annular guard plate 28 and the lower annular guard plate 29 are made of anti-corrosive rubber material with a buffering effect; during the handling and transportation of the storage barrel 11, when adjacent storage barrels 11 collide and rub against each other, the upper annular guard plate 28 and the lower annular guard plate 29 can respectively provide buffering protection to the upper annular airbag 22 and the lower annular airbag 26 in time, avoiding damage to the upper annular airbag 22 and the lower annular airbag 26 due to intense friction, which affects their shock absorption effect on the storage barrel 11.

[0029] Embodiment 3 On the basis of Embodiment 1, as Figures 1-7 shown in the figure, the wave baffle structures 111 in the storage barrel 11 of this embodiment are all set as upwardly convex annular conical surface structures; during the process of pouring out the liquid chemical raw materials in the storage barrel 11, the wave baffle structures 111 in the storage barrel 11 will be inverted into downwardly concave annular inclined surface structures, and the liquid chemical raw materials in the storage barrel 11 will completely pour out along the annular inclined surface structures of the wave baffle structures 111, avoiding waste caused by a large amount of liquid chemical raw materials remaining between the wave baffle structures 111 and the storage barrel 11.

[0030] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention.
