Description

Technical Field

[0001] This utility model relates to the field of extraction tank technology, specifically an interlocking self-controlled high-pressure extraction tank. Background Technology

[0002] High-pressure extraction tanks are commonly used in pharmaceutical, chemical, and bio-fermentation fields for high-temperature and high-pressure extraction of plant, traditional Chinese medicine, or chemical raw materials. To ensure the sealing and operational safety of the extraction process, the tank body and sealing cap are typically connected via a bolted locking structure or a mechanical locking mechanism using a flange connection.

[0003] Currently, most common structures use manual distributed locking devices, which involve setting up several independent locking mechanisms or pin structures around the tank flange. Operators need to operate them manually one by one, requiring multiple points of operation each time the tank is opened or closed. This is inefficient and prone to problems such as incomplete operation and partial inadequate locking. Especially under high pressure, partial locking failure can easily lead to abnormal pressure relief or even structural rupture, posing a safety hazard.

[0004] Some improved structures employ a single-point linkage locking mechanism, where a rotating ring drives a pin to insert, achieving a certain degree of structural linkage. However, such structures often rely on complex gear or cam mechanisms, resulting in complex manufacturing processes, high costs, and a susceptibility to problems like increased sliding clearance and mechanism jamming during long-term use, affecting reliability. Existing high-pressure extraction tank locking mechanisms generally lack self-locking functionality. Even with the pin inserted, some structures cannot effectively prevent the locking rod from shifting and falling off due to vibration or thermal expansion and contraction during high-pressure operation, leading to locking failure. Furthermore, most structures lack secondary limit protection and automatic reset capability after pin insertion, increasing the risk of human error.

[0005] Therefore, existing high-pressure extraction tanks still have key problems in terms of locking structure, such as poor synchronization, unstable sealing, and lack of automatic reset and interlocking control. There is an urgent need for a high-pressure extraction tank with simple structure, convenient operation, reliable sealing, and linkage and self-locking functions to improve the safety and efficiency of the equipment in high-pressure environments. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an interlocking self-controlled high-pressure extraction tank, comprising: a tank body, a sealing cover, a locking mechanism, a linkage ring, and a locking rod. The core technical point is that by using multiple sets of linkage locking mechanisms set at the flange connection, the locking structure can be automatically aligned, quickly locked, and subjected to secondary anti-detachment control under high pressure. A flange ring structure is provided between the tank body and the sealing cover, and the locking mechanism and locking rod are respectively set at corresponding positions on the tank body flange and the sealing cover flange, achieving positioning and locking through structural cooperation. Specifically, this flange structure facilitates stable connection and uniform force distribution, ensuring sealing reliability under high pressure.

[0008] In a preferred example, the locking mechanism includes a moving meniscus, a stationary meniscus, and an elastic element. The moving meniscus is mounted on the inner wall surface of the linkage ring, and the stationary meniscus is fixed to the outer side of the tank flange, with the two arranged opposite to each other. The elastic element is connected to both ends of the stationary meniscus and contacts the moving meniscus, and is used to drive the moving meniscus to automatically reset. Specifically, this structure ensures that the moving meniscus automatically returns to its initial position after operation, improving operational safety and the system's structural self-locking capability.

[0009] In a preferred example, both the moving and stationary menisci have locking grooves on their opposing surfaces, and they remain misaligned in the default state. The moving menisci are deflected by the rotation of the linkage ring, so that they align with the locking grooves on the stationary menisci to form a through hole. The locking rod is inserted through the through hole and locked into the groove to achieve locking. Specifically, this design has the ability to prevent misoperation, ensuring that the locking rod can only be inserted when it is correctly aligned, preventing accidental locking or unlocking.

[0010] In a preferred example, multiple locking mechanisms are evenly arranged along the circumference of the tank flange, with the moving meniscus mounted on the surface of the linkage ring and the stationary meniscus fixed to the tank flange. The deflection of each moving meniscus is controlled by the unified rotation of the linkage ring, forming a synchronously aligned locking operation. Specifically, this structure can significantly improve operating efficiency, reduce human intervention errors, and enhance the overall interlocking consistency.

[0011] In a preferred example, the surface of the locking bar is provided with a groove whose height matches the thickness of the moving and stationary menisci; after the moving menisci are reset under the action of the elastic element, their locking groove is inserted into the inner side of the groove to form a snap-fit ​​secondary limiting structure; specifically, this structure enhances the locking reliability and prevents the locking bar from being dislodged under high pressure.

[0012] In a preferred example, to ensure the sliding stability of the moving meniscus deflection, a sliding pin structure is provided on the surface of the tank. The sliding pin slides with the moving meniscus to guide it to deflect along a predetermined path. Specifically, this structure improves the stability and mechanical life of the locking mechanism during the deflection process and avoids jamming or offset problems.

[0013] In summary, this utility model achieves automatic alignment, rapid locking, and structural anti-detachment functions of the high-pressure extraction tank during the locking phase by setting a linkage ring to control the deflection of multiple sets of moving menisci and combining the cooperation and elastic reset of the stationary menisci. This not only improves the ease of operation but also significantly enhances the structural sealing stability and safety of use, making it suitable for industrial extraction applications with high requirements for sealing performance and operational efficiency.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, by setting multiple locking mechanisms at the connection between the tank body and the sealing cover flange, and using a linkage ring to uniformly drive the deflection and alignment of the moving meniscus, synchronous interlocking control of multiple locking structures is achieved. While improving the convenience of operation, it effectively enhances the safety and consistency of the sealing locking process, and meets the requirements of structural reliability and sealing stability under high pressure environment.

[0016] 2. In this utility model, the locking mechanism adopts a through-hole structure that can be deflected and aligned by the mating groove of the moving meniscus and the stationary meniscus, and achieves secondary locking by resetting through the elastic element. After the locking rod is inserted, it forms an anti-disengagement positioning in the groove. The overall structure has comprehensive advantages such as protection against misoperation, quick reset, and reliable locking, which significantly improves the safety, stability and interlocking efficiency of the equipment.

[0025] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an interlocked self-controlled high-pressure extraction tank.

[0028] Combination Figures 1-5 As shown, the present invention provides an interlocking self-controlled high-pressure extraction tank, comprising: a tank body 100, a sealing cover 110, a locking mechanism 200, a linkage ring 300, and a locking rod 400.

[0029] The tank body 100 has a cylindrical structure, with a flange connection at its top that mates with the sealing cover 110. The bottom of the sealing cover 110 also has a flange ring structure to achieve a tight seal between the top and bottom. The tank body 100 and the sealing cover 110 are connected and fixed at the flange ring by multiple locking mechanisms 200 to achieve a closed structure.

[0030] The locking mechanism 200 includes a moving meniscus 210, a stationary meniscus 220, an elastic element 230, and a locking groove 211. The moving meniscus 210 is disposed on the inner wall surface of the linkage ring 300, and the stationary meniscus 220 is fixed to the flange ring surface of the tank body 100. The moving meniscus 210 and the stationary meniscus 220 are arranged in pairs corresponding to each other. Each pair of moving meniscus 210 and stationary meniscus 220 has a locking groove 211 on their opposite surfaces. The locking groove 211 remains misaligned under normal conditions and does not form a through hole.

[0031] The linkage ring 300 has a ring structure and is fitted and rotatably mounted on the outer wall surface of the tank 100. The moving meniscus 210 is fixedly connected to the inner wall of the linkage ring 300. As the linkage ring 300 rotates, the moving meniscus 210 deflects under the action of the guide structure. By manually rotating the linkage ring 300, the moving meniscus 210 can be deflected, so that the groove 211 on its surface aligns with the groove 211 on the stationary meniscus 220, forming a through-hole structure.

[0032] In the aligned state, the operator can insert the locking rod 400 into the circular hole formed by the moving meniscus 210 and the stationary meniscus 220 to achieve positioning and locking. The surface of the locking rod 400 is provided with a groove 410. After insertion, under the action of the elastic element 230, the moving meniscus 210 returns to its initial position, causing its locking groove 211 to misalign with the stationary meniscus 220 again, and inserting into the inside of the groove 410 of the locking rod 400 to achieve secondary snap-fit ​​locking and enhance locking stability.

[0033] The elastic element 230 is a spring structure, located on both sides of the stationary meniscus 220, used to apply a restoring force to the moving meniscus 210, so that it automatically returns to its locked position when the external force is removed. The elastic element 230 is adapted to the surface of the moving meniscus 210 to achieve stable reset control.

[0034] In the actual structure, multiple locking mechanisms 200 are evenly distributed circumferentially along the flange ring of the tank body 100. Each moving meniscus 210 is positioned opposite to the stationary meniscus 220 and is uniformly driven by the linkage ring 300, avoiding cumbersome operation and improving synchronization and interlocking. During the linkage operation, all moving meniscus 210 deflect simultaneously under the drive of the linkage ring 300, and after being aligned by the locking groove 211, multiple locking rods 400 are uniformly inserted to form a multi-point locking structure, improving sealing and pressure resistance stability.

[0035] To improve the stability of the deflection motion, the flange of the tank body 100 is also provided with several sliding pin structures. The sliding pins are slidably sleeved on the outer edge surface of the moving meniscus 210 to guide the moving meniscus 210 to deflect along a specific trajectory and prevent deviation or jamming.

[0036] The through-hole structure formed by the buckle groove 211 on the surface of the moving meniscus 210 and the stationary meniscus 220 is adapted to the diameter of the locking rod 400, ensuring smooth insertion and accurate positioning, and avoiding structural loosening or gap errors.

[0037] In general, when using this invention, the operator first aligns the sealing cap 110 with the flange ring of the tank body 100, then rotates the linkage ring 300 to rotate and align the moving meniscus 210. After inserting the locking rod 400, the operator releases the linkage ring, and the moving meniscus 210 automatically returns to its original position, achieving rapid locking. After the extraction process is completed, the linkage ring is rotated in the opposite direction to release the lock, allowing the sealing cap to be removed and the entire operation to be completed.

[0038] Working principle and usage process of this utility model:

[0039] like Figure 5 As shown, this utility model improves the safety and ease of operation of the equipment by setting several sets of locking mechanisms at the connection between the tank body and the sealing cover flange of the high-pressure extraction tank, and combining them with the rotation operation of the linkage ring.

[0040] In actual use, the operator first covers the tank with the sealing cap, aligning its flange ring with the tank flange ring. At this time, among the multiple locking mechanisms 200, the moving meniscus 210 on the linkage ring 300 and the stationary meniscus 220 fixed on the tank flange ring are initially misaligned, that is, the two locking slots 211 are not aligned, and the locking rod 400 cannot be inserted, thereby preventing accidental locking and misoperation.

[0041] When the operator rotates the linkage ring 300 clockwise or counterclockwise, multiple movable menisci 210 fixed to its surface deflect and move under the drive of the linkage ring, causing the movable menisci 210 to align with the locking grooves on the stationary menisci 220. This forms a prototype through-hole structure to facilitate the insertion of the locking rod 400. After the locking rod 400 is inserted, under the elastic force of the elastic element 230, the movable menisci 210 can automatically reset, causing the locking grooves 211 to misalign, so that the movable menisci 210 can be inserted into the inner side of the receiving groove 410 to achieve the locking effect.

[0042] After locking is completed, during high-pressure extraction, the sealing cap is reliably connected to the tank flange, and the locking rod 400 achieves radial limiting through each latching groove 410, thereby effectively preventing the structure from loosening under high pressure; the elastic element 230 continuously provides elastic resistance, so that the interlocking mechanism is always in the locked state.

[0043] After extraction, the operator can manually rotate the linkage ring in the opposite direction to deflect the moving meniscus 210 and misalign the locking groove 211, thereby enabling quick unlocking and removal of the locking rod 400. The sliding pin guides the sliding process of the moving meniscus 210, improving operational smoothness and reliability.

[0044] In summary, this utility model achieves automatic structural alignment, rapid locking, and safe sealing under high pressure by using a linkage ring to uniformly control multiple locking mechanisms. It simplifies the operation process, improves sealing reliability, and is suitable for process scenarios with strict requirements for sealing and interlocking, such as high-pressure extraction.
