Description

Technical Field

[0001] This utility model relates to the field of C4 raw material storage technology, and in particular to a C4 raw material tank. Background Technology

[0002] In the chemical production field, C4 feedstock, as an important basic chemical raw material, is widely used in many key stages such as olefin production and rubber synthesis. As core equipment for storing and transferring these flammable, explosive, and volatile feedstocks, the sealing performance, convenience, and safety of C4 feedstock tanks directly affect the stability of the production process, the control of feedstock loss, and the safety of operators. Therefore, optimizing the structure and improving the performance of C4 feedstock tanks has always been a key focus of chemical equipment research and development. Existing C4 feedstock tanks typically use fixed doors that are welded or bolted to the tank body. Sealing relies on the pressure between a rubber sealing ring at the door edge and the tank flange. When cleaning or maintenance is required inside the tank, operators often need to use wrenches, screwdrivers, and other tools to remove numerous bolts, a tedious and time-consuming process. Furthermore, frequent disassembly and reassembly can easily cause the rubber sealing ring to deform or break, leading to a decrease in sealing performance. However, the existing process of connecting and disassembling the doors of C4 feedstock tanks is complicated, resulting in low efficiency in cleaning and maintenance of the tank interior. Prolonged exposure to air also increases the risk of feedstock contamination. Furthermore, traditional sealing methods are difficult to maintain a good sealing effect for a long time, which can easily lead to feedstock leakage, resulting in feedstock waste and safety hazards.

[0016] 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.

[0017] Reference Figures 1-3This utility model provides an embodiment of a C4 raw material tank, including a raw material tank frame 1. An arc-shaped connecting plate 2 is rotatably connected to one side of the top of the raw material tank frame 1. A sealing door 3 is provided at one end of the arc-shaped connecting plate 2. The sealing door 3 is a closing component of the raw material tank frame 1. When closed, it cooperates with the tank opening sealing ring 9 and achieves a seal through the sealing ring 8 to prevent leakage of C4 raw material. When opened, it facilitates cleaning, maintenance and other operations inside the raw material tank frame 1. The top of the raw material tank frame 1 is fixedly connected to the tank opening sealing ring 9, and the top of the tank opening sealing ring 9 is fixedly connected to the sealing ring 8. An opening and closing assembly is provided on the outer wall of the sealing door 3. The opening and closing assembly includes a limit latch 7, which cooperates with the locking block 11 to fix the sealed door 3, ensuring its stability during use and preventing accidental opening. When it is necessary to open the sealed door 3, the limit latch 7 is pulled to disengage from the locking block 11, releasing the fixation and realizing the preparatory operation for opening the sealed door 3. The assembly also includes a polygonal arc-shaped limit plate 10 and the locking block 11. The locking block 11 serves as the locking object of the limit latch 7, and together with the limit latch 7, it forms the fixing structure of the sealed door 3. The structure ensures the stability of the sealed door 3 in the closed state. A polygonal arc-shaped limiting plate 10 is fixedly connected to the bottom of the sealed door 3, and a snap-fit ​​block 11 is fixedly connected to one side of the outer wall of the sealed door 3. A limiting buckle 7 is located on the top of the raw material tank frame 1 on the other side. A rotating shaft 4 is rotatably connected inside the arc-shaped connecting plate 2. A gear 2 5 is fixedly connected to the bottom of the rotating shaft 4. The gear 2 5 meshes with an arc-shaped toothed plate 6 and rotates under the drive of the rotating shaft 4, transmitting the rotational motion to the arc-shaped toothed plate 6 to drive the sealed door 3 to rotate. A curved toothed plate 6 is fixedly connected to the outer wall of the sealed compartment door 3 on the side away from the snap-fit ​​block 11. The curved toothed plate 6 cooperates with the gear 5 to convert the rotational motion of the gear 5 into the rotational motion of the sealed compartment door 3. The gear 5 meshes with the curved toothed plate 6. The outer wall of the limiting buckle 7 is slidably connected to the inside of the snap-fit ​​block 11. The sealing ring 8 is set between the sealed compartment door 3 and the tank opening sealing ring 9. The sealing ring 8 is installed between the sealed compartment door 3 and the tank opening sealing ring 9. Through tight fit, it fills the gap and plays a sealing role. To prevent C4 raw materials from leaking from the connection between the sealed door 3 and the tank opening sealing ring 9, the outer wall of the polygonal arc-shaped limiting plate 10 is slidably connected to the inner wall of the tank opening sealing ring 9. When the sealed door 3 is closed, the polygonal arc-shaped limiting plate 10 cooperates with the inner wall of the tank opening sealing ring 9 to restrict the position of the sealed door 3 and ensure accurate docking between the sealed door 3 and the tank opening sealing ring 9. At the same time, during the opening process of the sealed door 3, as the sealed door 3 rotates away from the inner wall of the tank opening sealing ring 9, it creates conditions for the separation of the sealed door 3 from the raw material tank frame 1.

[0018] Specifically, when using the C4 raw material tank, pull the limiting buckle 7 to disengage it from the locking block 11, releasing the fixation on the sealed door 3. The drive shaft 4 drives the gear 5 to rotate, and the meshing relationship between the arc-shaped toothed plate 6 and the gear 5 causes the sealed door 3 to rotate. When the sealed door 3 rotates to the appropriate angle, the polygonal arc-shaped limiting plate 10 disengages from the inner wall of the tank opening sealing ring 9, and pulling the arc-shaped connecting plate 2 separates the sealed door 3 from the raw material tank frame 1. The sealing ring 8 effectively seals the sealed door 3 and the tank opening sealing ring 9, preventing leakage, facilitating cleaning of the inside of the raw material tank frame 1, and also contributing to sealing.

[0019] Reference Figure 1 , Figure 4 and Figure 5 A solenoid valve 12 is fixedly connected to the top of the sealed door 3. The input end of the solenoid valve 12 is fixedly connected to the installation pipe 13. The installation pipe 13 is an important component connecting the pipeline to the raw material tank and cooperates with the connecting ring 20. The upper surface of the installation pipe 13 is fitted with the connecting ring 20. The connecting ring 20, as a connecting component in the pipeline connection, cooperates with the installation pipe 13, the fixing rod 21, etc., to realize the connection between the pipeline and the raw material tank. The top of the connecting ring 20 is fixedly connected to the fixing rod 21, and the bottom of the connecting ring 20 is fixedly connected to the rubber plate 18. The rubber plate 18 is located between the connecting ring 20 and the installation pipe 13, reducing the friction between the connecting ring 20 and the installation pipe 13 during installation, disassembly, and use, and also playing a buffering role to protect the pipeline surface from damage. The outer wall of the connecting ring 20 is provided with a fixing component, which includes a rotating sleeve 16. The rotating sleeve 16 can rotate freely on the outer wall of the fixing block 14 and the rotating shaft 15, covering the connecting ring 20 and the... The connection part of the mounting tube 13 enhances the stability of the connection between the connecting ring 20 and the mounting tube 13. The rotating sleeve 16 is set on the outer wall of the connecting ring 20. The upper surface of the connecting ring 20 is fixedly connected to the fixing block 14. The outer wall of the fixing block 14 is fixedly connected to the rotating shaft 15. The fixing block 14 and the rotating shaft 15 provide rotational support for the rotating sleeve 16, ensuring that the rotating sleeve 16 can rotate flexibly and helping to enhance the stability of the connection between the connecting ring 20 and the mounting tube 13. The rotating sleeve 16 is provided with a threaded rod 17 inside. The mounting tube 13 and the connecting ring 20 are both provided with mounting holes 19 inside. The outer wall of the threaded rod 17 passes through the mounting holes 19 inside the mounting tube 13 and the connecting ring 20. The rotating shaft 15 is rotatably connected to one end of the rotating sleeve 16, so that the rotating sleeve 16 can rotate with the rotating shaft 15 as the center. The rubber plate 18 is set between the connecting ring 20 and the mounting tube 13. The rotating sleeve 16 is wrapped around the outer wall of the connecting ring 20 and the mounting tube 13.

[0020] Specifically, regarding pipe connections, the rubber plate 18 between the connecting ring 20 and the mounting pipe 13 reduces friction and provides cushioning protection for the pipe. Pulling the rotating sleeve 16 to cover the connection area allows it to rotate freely between the fixed block 14 and the outer wall of the rotating shaft 15, enhancing connection stability. Finally, the threaded rod 17 passes through the connecting ring 20, mounting pipe 13, and rotating sleeve 16 for fixation, and in conjunction with the solenoid valve 12, facilitates convenient loading and unloading of raw materials.

[0021] Working principle: When the C4 raw material tank is needed, first pull the limit buckle 7 to disengage it from the inside of the snap-fit ​​block 11, thereby releasing the fixation between the snap-fit ​​block 11 and the sealing door 3. Then, drive the rotating shaft 4 to rotate the gear 5. Combined with the meshing relationship between the arc-shaped toothed plate 6 and the gear 5, the sealing door 3 is rotated. When the sealing door 3 rotates to a certain angle, the polygonal arc-shaped limit plate 10 can be disengaged from the inner wall of the tank opening sealing ring 9. Then, pull the arc-shaped connecting plate 2 to separate the sealing door 3 from the raw material tank frame 1. In addition, the sealing ring 8 can be used to seal the sealing door 3 and the tank opening sealing ring 9 to prevent leakage, thereby facilitating the cleaning of the inside of the raw material tank frame 1 and facilitating the sealing of the raw material tank frame 1. In addition, a rubber plate 18 is specially provided between the connecting ring 20 and the mounting pipe 13, which can not only reduce friction but also act as a buffer to protect the surface of the pipe from damage. Next, the rotating sleeve 16 is pulled to allow it to rotate freely on the outer wall of the fixed block 14 and the rotating shaft 15, so that the rotating sleeve 16 can completely cover the connection part between the connecting ring 20 and the mounting pipe 13, further enhancing the stability of the connection. Finally, the threaded rod 17 is fixed by passing through the connecting ring 20, the mounting pipe 13 and the rotating sleeve 16, thereby achieving the fixation of the connecting ring 20 and the fixed rod 21, and thus facilitating the loading and unloading of raw materials in conjunction with the solenoid valve 12.
