[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] To address the technical problem of inconvenient maintenance of gas buffer tanks, this utility model provides a gas buffer tank that allows for convenient replacement or maintenance of the buffer structure by adjusting the position of the connecting tank, thereby improving the convenience and efficiency of maintenance.

[0033] It should be noted that the gas buffer tank described in this utility model is used for, but not limited to, the transportation of light hydrocarbon fuels. For ease of explanation, this utility model only uses the application of the gas buffer tank to the transportation of light hydrocarbon fuels as an example. The principle of the gas buffer tank in other types of gas transportation is essentially the same as that in the transportation of light hydrocarbon fuels, and will not be described in detail here.

[0034] Please see Figures 1 to 3 The gas buffer tank includes: a tank body 1, a buffer structure 2, and a connecting structure 3. The tank body 1 includes a tank top 111, a connecting tank 12, a tank bottom 13, an inlet pipe 14, and an outlet pipe 15. The two ends of the connecting tank 12 are detachably connected to and communicate with the tank top 111 and the tank bottom 13, respectively. The inlet pipe 14 and the outlet pipe 15 are respectively located at the tank top 111 and the tank bottom 13. The buffer structure 2 is installed inside the connecting tank 12. The connecting structure 3 is connected to the tank top 111 and / or the tank bottom 13. The connecting tank 12 is rotatably connected to the connecting structure 3. The rotation path of the connecting tank 12 around the connecting structure 3 has a first position communicating with the tank top 111 and the tank bottom 13, and a second position isolated from the tank top 111 and the tank bottom 13.

[0035] In this device, the connecting tank 12 is positioned between the tank top 111 and the tank bottom 13. The inlet pipe 14 and outlet pipe 15 are respectively located at the tank top 111 and the tank bottom 13, allowing light hydrocarbon gas to enter the tank body 1 from the tank top 111 through the inlet pipe 14, flow through the connecting tank 12 to the tank bottom 13, and finally exit from the outlet pipe 15. The buffer structure 2 within the connecting tank 12 effectively slows down the gas flow rate, reduces the impact of gas on the inner wall of the tank body 1, and minimizes noise and wear. Simultaneously, the connection of the connecting structure 3 to the tank top 111 and / or the tank bottom 13, and the rotatable connection between the connecting tank 12 and the connecting structure 3, allow the connecting tank 12 to rotate around the connecting structure 3. When the connecting tank 12 is in the first position, it is aligned with the tank top 111 and the tank bottom 13, allowing gas to flow smoothly through the connecting tank 12. When the buffer components are damaged or require maintenance, simply rotate the connecting tank 12 around the connecting structure 3 to the second position. At this time, the connecting tank 12 is offset from the top 111 and the bottom 13 of the tank, making it easy to replace or maintain the buffer structure 2 without disassembling the entire tank 1.

[0036] For easy connection of can 12 and sealing, please refer to [link / reference]. Figure 1 and Figure 2In some possible embodiments, a lifting drive 4 is also provided between the tank bottom 13 and the tank top 111. The lifting drive 4 connects the tank top 111 and the tank bottom 13 and is used to drive the tank top 111 to perform lifting and lowering actions. When it is necessary to rotate and move the connected tank 12 to a second position, the lifting drive 4 can be used to raise the tank top 111 to a certain height, providing sufficient space for the rotation of the connected tank 12. When it is necessary to fix the connected tank 12 in the first position, the lifting drive 4 can be used to lower the tank top 111 back to its original position, thereby fixing the connected tank 12.

[0037] To ensure stability during the lifting and lowering process of the tank top 111, and to prevent the lifting drive component 4 from obstructing the rotation of the connected tank. Please refer to... Figures 1 to 3 In some possible embodiments, the lifting drive 4 is provided in at least two sets, and at least two sets of lifting drive 4 are located outside the rotation path of the connecting tank 12 to ensure that the lifting drive 4 does not interfere with the connecting tank 12.

[0038] In one preferred embodiment, the lifting drive component 4 is provided in three sets, two of which are located opposite each other on both sides of the tank body 1, and the other set is located at the front or rear end of the tank body 1. The three sets of lifting drive components 4 work together to improve the stability of the tank top 111 during the lifting process, and also ensure the balance of the tank body 1 during the lifting process, while not affecting the rotation of the connected tank 12.

[0039] In one embodiment, please refer to Figure 1 and Figure 2 The lifting drive component 4 is a screw drive structure. Each lifting drive component 4 includes a drive motor 41, a mounting base 42, a lead screw 43, and a nut seat 44. The drive motor 41 is mounted on one side of the tank top 111 via the mounting base 42. The mounting base 42 is slidably connected to the tank top 111 and can slide up and down along the outer wall of the tank top 111. One end of the lead screw 43 is fixedly connected to the output shaft of the drive motor 41, and the other end passes through the nut seat 44 and is rotatably connected to the tank bottom 13. The nut seat 44 is threadedly connected to the lead screw. When the drive motor 41 starts, the output shaft of the drive motor 41 drives the lead screw 43 to rotate. Since the nut seat 44 is threadedly connected to the lead screw 43, the nut seat 44 will move along the axial direction of the lead screw 43. When the drive motor 41 rotates forward, the nut seat 44 moves upward, causing the tank top 111 to rise; when the drive motor 41 rotates in reverse, the nut seat 44 moves downward, causing the tank top 111 to fall. Since the mounting base 42 is slidably connected to the tank top 111, it can slide up and down along the outer side wall of the tank top 111. Therefore, when the tank top 111 is raised or lowered, the mounting base 42 can remain stationary relative to the tank bottom 13, ensuring the stable operation of the lifting drive component 4.

[0040] Please see Figures 1 to 3In one embodiment, the connecting structure 3 includes a connecting shaft 31 and a connecting seat 32. The connecting seat 32 is fixed to one side of the tank bottom 13. One end of the connecting shaft 31 is rotatably connected to the connecting seat 32, and the other end is coaxially connected to the lead screw of one of the screw drive structures. One side of the connecting tank 12 is sleeved with the connecting shaft 31, allowing it to rotate around the connecting shaft 31 and slide up and down. A handle 121 is provided on the side wall of the connecting tank 12, which allows the operator to manually rotate the connecting tank 12. When it is necessary to rotate the connecting tank 12 to the second position, the lifting drive 4 drives the tank top 111 to rise to a certain height. Then, the operator can hold the handle 121 to lift the connecting tank 12 upwards, separating it from the tank bottom 13, and then manually rotate the connecting tank 12 to rotate it to the second position. After the connecting tank 12 is rotated to the desired position, it is slowly lowered to ensure the stability and safety of the rotation of the connecting tank 12.

[0041] Of course, in other possible embodiments, the lifting drive 4 can also be manually driven, for example, by rotating the lead screw through a hand crank to achieve the lifting action of the tank top 111, in order to adapt to different usage environments and needs. The lifting drive 4 can also adopt other transmission structures, such as worm gear transmission structure, belt transmission structure or chain transmission structure, as long as it can meet the lifting requirements of the tank top 111 and ensure stability during the lifting process.

[0042] To ensure stability during the installation of connecting tank 12, please refer to... Figure 2 and Figure 4 In some possible embodiments, the connecting tank 12 has an annular connecting protrusion 122 at one end corresponding to the tank top 111, and the outer diameter of the annular connecting protrusion 122 matches the inner diameter of the tank top 111. After the connecting tank 12 is installed, the annular connecting protrusion 122 can be embedded into the tank top 111, achieving a tight fit between the connecting tank 12 and the tank top 111. This design not only ensures the coaxiality of the connecting tank 12 during installation, but also effectively enhances the local wall thickness by adding the annular connecting protrusion 122 at the segment, thereby significantly improving the overall pressure-bearing capacity.

[0043] Please see Figure 1 , Figures 3 to 5 In some possible embodiments, the gas buffer tank also includes two sets of sealing structures 5, which are respectively disposed between the connecting tank 12 and the tank top 111 and the connecting tank 12 and the tank bottom 13. The connecting tank 12 and the tank top 111 and the connecting tank 12 and the tank bottom 13 are detachably sealed together by the sealing structures 5 to ensure that the connecting tank 12 can maintain good sealing performance with the tank top 111 and the tank bottom 13 in both rotating and fixed states.

[0044] In one possible embodiment, each sealing structure 5 includes two flanges 51, several connecting bolts 52, and an annular sealing ring 53. One flange 51 is fixedly connected to the end face of the connecting tank 12 and is sleeved on the connecting shaft 31 for rotatable engagement. The other flange 51 is fixedly connected to the corresponding position of the tank top 111 or the tank bottom 13. Several connecting bolts 52 pass through and connect the two flanges 51. An annular sealing gasket is embedded between the mating surfaces of two adjacent flanges 51. In addition, an annular sealing gasket is also provided between the connecting tank 12 and the tank top 111, and between the connecting tank 12 and the tank bottom 13. When the tank top 111 moves downward, it can squeeze the annular sealing gasket, causing it to undergo elastic deformation, thereby filling the tiny gap between the connecting tank 12 and the tank top 111 or the tank bottom 13, further improving the sealing effect.

[0045] Furthermore, in some possible embodiments, the sealing structure 5 also includes a positioning element 6, which is a positioning pin or positioning block, etc., to ensure the accurate positioning of the two flanges 51 during the connection process. There are corresponding sockets between two adjacent flanges 51, and the positioning element 6 is inserted into the sockets of the two adjacent flanges 51 to achieve accurate positioning of the two flanges 51 during connection, avoid misalignment, and ensure the stability and reliability of the sealing structure 5.

[0046] Please see Figure 2 and Figure 6 To ensure a buffering effect, in some possible embodiments, multiple sets of buffer structures 2 are provided. These multiple sets of buffer structures 2 are arranged sequentially within the connecting tank 12 along the material flow direction, with each buffer end corresponding to the air inlet pipe, to further slow down the gas flow velocity and enhance the buffering effect. Each set of buffer structures 2 may include an arc-shaped buffer plate 21, an elastic element 22, and a mounting plate 23. The buffer plate 21 is disposed within the connecting tank 12 to block the direct impact of the gas. The mounting plate 23 is fixed within the connecting tank 12 by bolts. The elastic element 22 connects the buffer plate 21 and the mounting plate 23. When the gas impacts the buffer plate 21, the buffer plate 21 is subjected to pressure and moves downward, compressing the elastic element 22. The compression and recovery process of the elastic element 22 can consume the kinetic energy of the gas, thereby slowing down the gas flow velocity. The arrangement of multiple sets of buffer structures 2 allows the gas to be buffered multiple times during the flow process, further reducing the gas impact force and noise, while extending the service life of the tank 1.

[0047] Furthermore, in some possible embodiments, each buffer plate 21 is provided with an elastic element 22 at both ends. The elastic element 22 is a shock absorber, which is mounted on the mounting plate 23. The top end of the shock absorber is rotatably connected to the buffer plate 21, and the other end of the buffer plate 21 is rotatably connected to the buffer plate 21 and the mounting plate 23. When gas impacts the buffer plate 21, the buffer plate 21 will swing slightly around the mounting point of the shock absorber after being subjected to the impact force of the gas. This allows it to better adapt to the flow direction of the gas, thereby improving the buffering effect.

[0048] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: When it is necessary to replace or maintain the buffer components, the lifting drive 4 is activated, causing the output shaft of the drive motor 41 to drive the lead screw 43 to rotate. Since the nut seat 44 is threadedly connected to the lead screw 43, the nut seat 44 will move upward along the axial direction of the lead screw 43, causing the top of the can 111 to rise, providing sufficient space for the rotation of the connecting can 12. Then, the operator can hold the handle 121 provided on the side wall of the connecting can 12 and lift the connecting can 12 upward, separating it from the bottom of the can 13. Subsequently, the operator can manually rotate the connecting can 12, rotating it from the first position connected to the top of the can 111 and the bottom of the can 13 to the second position isolated from the top of the can 111 and the bottom of the can 13. After the connecting can 12 is rotated to the required position, the operator can slowly lower the connecting can 12 to replace or maintain the buffer structure 2. After maintenance, the operator can rotate the connecting can 12 back to the first position in reverse order, and use the lifting drive 4 to lower the top of the can 111 back to its original position, thus fixing the connecting can 12.

[0049] This utility model, through the arrangement of a tank body 1, a buffer structure 2, and a connecting structure 3, and the detachable connection of a tank top 111, a connecting tank 12, and a tank bottom 13, and the connecting structure 3 that can support the rotation of the connecting tank 12, allows the connecting tank 12 to rotate around the connecting structure 3 to communicate with or isolate itself from the tank top 111 and the tank bottom 13. When it is necessary to replace or maintain the buffer components of the buffer structure 2, the connecting tank 12 is rotated to a second position, so that the connecting tank 12 is misaligned with the tank top 111 and the tank bottom 13, which makes it convenient to replace or maintain the buffer structure 2, improving the convenience and efficiency of maintenance.
