[0032] Before using this equipment, the operator sequentially inserts PTFE liners 9 into the multiple holding chambers 4, then inserts bottom gaskets 8 into the PTFE liners 9, then inserts the digestion inner liner 702 into the PTFE liners 9, then fills the multiple chambers 792 with the samples to be digested, and then covers the PTFE digestion top cover 6. The digestion inner liner top ring 7 and the top cover support ring 601 ensure the sealing of the digestion inner liner 702. The digestion inner liner buckle 701 and the top cover buckle 602 further ensure the sealing of the digestion inner liner 702. The operator then lifts the limiting rod positioning plate 203, causing the limiting rod 205 to move upwards, which in turn moves the limiting block 202 upwards. The operator then rotates the limiting plate 2, opening the left side of the box 1. The operator then passes the box 1 through the... The left side of the box 1 is inserted into the box 1. When the rightmost holding cavity 4 is tightly against the limiting arc plate 101, the operator closes the limiting plate 2 and further loosens the limiting rod positioning plate 203, thereby locking the limiting block 202 against the limiting plate 2, thus achieving the purpose of positioning the positioning ring connecting rod 402, thereby fixing the holding cavity positioning ring 401, thus achieving the purpose of positioning the holding cavity 4, so that each holding cavity 4 is aligned with the box body thread 102. At this time, the operator places the top gasket 5 on the top of the polytetrafluoroethylene digestion cover 6 in sequence. The operator then rotates the pressure bolt head 301 by the pressure bolt rotating ring 302, thereby allowing multiple pressure bolts 3 to rotate, so that multiple pressure bolt rotating rings 302 can engage with the box body thread 102, so that multiple pressure bolts 3 can sequentially press the top gasket 5, thereby further ensuring the sealing of the digestion inner liner 702, thus ensuring the digestion effect.

[0033] The working process of this utility model is as follows: Before using this equipment, the operator sequentially inserts polytetrafluoroethylene (PTFE) liners 9 into the multiple holding cavities 4, then sequentially inserts bottom gaskets 8 into the PTFE liners 9, then sequentially inserts the digestion inner liner 702 into the PTFE liners 9, then sequentially fills the multiple 792 cavities with the samples to be digested, then sequentially covers the PTFE digestion top cover 6. At this time, the digestion inner liner top ring 7 and the top cover support ring 601 ensure the sealing of the digestion inner liner 702. At this time, the digestion inner liner buckle 701 and the top cover buckle 602 further ensure the sealing of the digestion inner liner 702. Then, the operator lifts the limiting rod positioning plate 203, thereby causing the limiting rod 205 to move upward, which in turn drives the limiting block 202 to move upward. Then, the operator rotates the limiting plate 2, thereby opening the left side of the box 1. At this time, the operator opens the box. Body 1 is inserted into the interior of the box 1 through the left side. When the rightmost holding cavity 4 is in close contact with the limiting arc plate 101, the operator closes the limiting plate 2 and further loosens the limiting rod positioning plate 203, thereby locking the limiting block 202 with the limiting plate 2, thus achieving the purpose of positioning the positioning ring connecting rod 402, thereby fixing the holding cavity positioning ring 401, thus achieving the purpose of positioning the holding cavity 4, so that each holding cavity 4 is aligned with the box thread 102. At this time, the operator places the top gasket 5 on the top of the polytetrafluoroethylene digestion cover 6 in sequence. The operator then rotates the pressure bolt head 301 by the pressure bolt rotating ring 302, thereby allowing multiple pressure bolts 3 to rotate, so that multiple pressure bolt rotating rings 302 can engage with the box thread 102, so that multiple pressure bolts 3 can sequentially press the top gasket 5, thereby further ensuring the sealing of the digestion inner liner 702, thus ensuring the digestion effect.
