[0002] Digestion vessels are used for sample pretreatment and sample dissolution in chemical analysis methods such as gas chromatography, liquid chromatography, inductively coupled plasma mass spectrometry, and atomic absorption spectrometry. High-pressure digestion vessels, also called high-pressure sealed vessels, high-pressure dissolution bombs, pressure digestion bombs, high-pressure digestion vessels, pressure digesters, and geological digestion vessels, are used in a high-temperature, high-pressure, sealed environment with strong acid or strong alkali, resulting in better digestion of poorly soluble substances. They can digest many samples that are difficult to digest using traditional methods, making them widely applicable. With the development of digestion technology, the requirements for efficient, rapid, and integrated digestion equipment or modules are becoming increasingly stringent.

[0003] However, existing digestion vessels are all single-unit digestion devices, lacking a highly efficient and rapid modular core interlocking module for the digester, resulting in low digestion efficiency and poor digestion effect. To address this issue, this invention designs a multi-position rapid interlocking module for a high-throughput digester. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a multi-position rapid fastening module for a high-throughput digester, which effectively solves the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1-3 , Figure 5The present invention includes a base plate 1 made of alloy material, which supports the entire device. The base plate 1 has multiple positioning holes 101 for facilitating the positioning of the bushing tube 9.

[0025] Each of the assembled sleeves 2 has a push-pull cover 3 on its top, which is made of alloy material and is used to position the pressure bolt 4. Each assembled sleeve 2 has a slidably connected bushing 9 inside, which is also made of alloy material and is used to position the polytetrafluoroethylene (PTFE) inner liner 602. Each bushing 9 has a PTFE inner liner 602 inside, which is also made of alloy material and is used to hold samples. Each PTFE inner liner 602 has a PTFE digestion cover 5 on its top, which is also made of alloy material and is used to ensure the sealing of the PTFE inner liner 602.

[0026] Each of the PTFE digestion cover 5 has an upper gasket 7 slidably connected to its top. The upper gasket 7 is made of rubber material and is used to connect the PTFE digestion cover 5 and the PTFE inner liner 602. Each upper gasket 7 has a pressure bolt 4 at its top. The pressure bolt 4 is made of alloy material and is used to press the PTFE digestion cover 5 to ensure the sealing of the PTFE inner liner 602. Each pressure bolt 4 has a pressure bolt rod 401 fixed at its top. The pressure bolt rod 401 is made of alloy material and is easy to rotate. Each pressure bolt rod 401 has a pressure bolt hole 402 for easy rotation of the pressure bolt rod 401.

[0027] Example 2, based on Example 1, is... Figure 4 , Figure 6Each bushing tube 9 has a lower gasket 8 slidably connected to its bottom inner end. The lower gasket 8 is made of rubber material and supports the polytetrafluoroethylene (PTFE) inner liner 602. Each lower gasket 8 has a PTFE lower liner 603 slidably connected to its top. The PTFE lower liner 603 is made of alloy material and has a spherical shell structure to facilitate sample reaction inside the PTFE inner liner 602. Each PTFE lower liner 603 is fixedly connected to the PTFE inner liner 602 at its top. Each PTFE inner liner 602 has a PTFE inner liner support ring 6 fixed to its top. The PTFE inner liner support ring 6 is made of alloy material and supports the PTFE digestion cover sealing ring 501, thereby ensuring the safety of the inner buckle 601.

[0028] Each of the PTFE inner liner support rings 6 has an inner buckle 601 fixed at its top. The inner buckle 601 has an arc-shaped structure and is sharpened to facilitate a tight fit between the PTFE digestion cover 5 and the inner buckle 601. Each inner buckle 601 has an outer buckle 502 slidably connected to its top, providing a channel for the inner buckle 601. Each outer buckle 502 is fixedly connected to the PTFE digestion cover 5 at its outer end. Each PTFE digestion cover 5 has a PTFE digestion cover sealing ring 501 fixed at its bottom. The polytetrafluoroethylene (PTFE) digestion cover sealing ring 501 is made of alloy material. The PTFE digestion cover sealing ring 501 cooperates with the PTFE inner liner support ring 6 to ensure the sealing of the PTFE inner liner 602. Each PTFE digestion cover sealing ring 501 is slidably connected to the PTFE inner liner support ring 6 at its bottom. The bottom of the multiple PTFE inner liner support rings 6 is slidably connected to a top positioning plate 202. The top positioning plate 202 is made of alloy material and is used to position the push-pull cover buckle 301.

[0029] The top positioning plate 202 is fixedly connected to the assembled sleeve 2 at its bottom. A set of push-pull cover buckles 301 are slidably connected to the outside of the top positioning plate 202. The push-pull cover buckles 301 are made of alloy material. The push-pull cover buckles 301 and the top positioning plate 202 cooperate to ensure that the push-pull cover 3 can only move left and right. The push-pull cover buckles 301 are fixedly connected to the push-pull cover 3 at its top. The push-pull cover 3 is provided with a plurality of push-pull cover nuts 302. Each push-pull cover nut 302 is internally engaged with a pressure bolt screw 403. The pressure bolt screw 403 and the push-pull cover nut 302 cooperate to allow the pressure bolt 4 to move up and down. Each pressure bolt screw 403 is fixedly connected to the pressure bolt 4 on its inner side.

[0030] When using this equipment, the operator inserts multiple bushings 9 into multiple assembled sleeves 2. Then, the operator inserts multiple lower gaskets 8 into the bushings 9. The positioning holes 101 on the base plate prevent the lower gaskets 8 from falling off. Next, the operator inserts multiple upper gaskets 7 into the lower gaskets 8. The bushings 9 facilitate the rotation of the upper gaskets 7. Then, the operator inserts a polytetrafluoroethylene (PTFE) inner liner 602 into the upper gaskets 7. The bottom of the PTFE lower liner 603 is tightly fitted to the lower gaskets 8. The operator then adds the sample to be digested into the PTFE inner liners 602. Finally, the operator attaches the PTFE digestion cover 5 to the top of the PTFE inner liners 602. The outer clip 502 and the inner clip 601 ensure a tight fit between the PTFE inner liner support ring 6 and the PTFE digestion cover sealing ring 501. At this point, the workers place gaskets 7 on top of each of the polytetrafluoroethylene (PTFE) digestion covers 5 in sequence. Then, using the push-pull cover buckle 301 and the top positioning plate 202, the workers position the push-pull cover 3 on top of the assembled sleeve 2. Next, by moving the push-pull cover 3, each push-pull cover nut 302 is positioned on top of multiple gaskets 7. Then, the workers screw multiple pressure bolts 4 into the multiple push-pull cover nuts 302 in sequence. Next, the workers insert a rotating rod into the pressure bolt hole 402 and rotate the pressure bolt rod 401, causing the pressure bolt 4 to rotate. At this point, due to the action of the pressure bolt screw 403 and the push-pull cover nuts 302, the multiple pressure bolts 4 can rotate downwards, thereby ensuring that the PTFE digestion cover sealing ring 501 is tightly attached to the PTFE inner liner support ring 6, thus guaranteeing the sealing of the multiple PTFE inner liners 602 and ensuring the digestion effect.

[0031] The working process of this utility model is as follows: When using this equipment, the operator inserts multiple bushings 9 into multiple assembled sleeves 2. Then, the operator inserts multiple lower gaskets 8 into multiple bushings 9. At this time, the positioning hole 101 on the bottom plate prevents the lower gaskets 8 from falling off. Next, the operator inserts multiple upper gaskets 7 into multiple lower gaskets 8 sequentially. At this time, the bushings 9 facilitate the rotation of the upper gaskets 7. Then, the operator inserts the polytetrafluoroethylene (PTFE) inner liner 602 into the upper gaskets 7. At this time, the bottom of the PTFE lower liner 603 is tightly fitted with the lower gaskets 8. Then, the operator adds the sample to be digested into multiple PTFE inner liners 602 sequentially. Finally, the operator attaches the PTFE digestion cover 5 to the top of the PTFE inner liner 602 sequentially. At this time, the outer buckle 502 and the inner buckle 601 ensure that the PTFE inner liner support ring 6 and the PTFE digestion cover sealing ring 50 are properly secured. 1. A tight fit is achieved. At this point, the worker places a gasket 7 on top of each of the PTFE digestion covers 5 in sequence. The worker then uses the push-pull cover buckle 301 and the top positioning plate 202 to position the push-pull cover 3 on top of the assembled sleeve 2. The worker then moves the push-pull cover 3 so that each push-pull cover nut 302 is positioned on top of multiple gaskets 7 in sequence. The worker then screws multiple pressure bolts 4 into the multiple push-pull cover nuts 302 in sequence. The worker then inserts a rotating rod into the pressure bolt hole 402 and rotates the pressure bolt rod 401 to rotate the pressure bolt 4. At this point, due to the action of the pressure bolt screw 403 and the push-pull cover nuts 302, multiple pressure bolts 4 can rotate downwards, thereby ensuring that the PTFE digestion cover sealing ring 501 is tightly fitted with the PTFE inner liner support ring 6, thus guaranteeing the sealing of multiple PTFE inner liners 602 and ensuring the digestion effect.
