A control component 206 is provided inside the sliding block 205; a connecting component 5 is disposed inside the fixed block 2 for connecting the heating seat 1 and the support seat 3; a moving component is disposed outside the fixed block 2 for moving the crucible. The moving component includes a clamping component 6 and a moving component 7. The moving component 7 is disposed inside the fixed block 2 for controlling the clamping component 6. The clamping component 6 is disposed inside the moving component 7 for clamping the crucible, and the clamping component 6 cooperates with the moving component 7 to adjust the position of the crucible. Specifically, when it is necessary to digest the sample... First, the heating base 1, the fixing block 2, and the support base 3 are connected sequentially via the connector 5. After digestion, the high-temperature crucible inside the placement rack 103 is moved to the heat dissipation rack 302 through the cooperation of the clamping part 6 and the moving part 7, thereby cooling the heated crucible. A control module is provided on the outside of the heating base 1. During use, the control module can control the heating time, heating temperature, clamping part 6, and moving part 7 to ensure that the crucible is heated and cooled simultaneously during the sample digestion process. The heat dissipation platform 301 is also provided with heat dissipation holes and a fan to control the airflow inside the heat dissipation platform 301 during use, thereby improving the cooling effect of the crucible. During use, the threaded rod 204 can drive the sliding block 205 to move inside the fixing block 2, thereby controlling the position movement of the moving part 7. The control part 206 is a rotary telescopic shaft, which can control the rotation and height adjustment of the moving part 7, thereby controlling the height and position adjustment of the crucible by the moving part 7 during use. The fixing block 2 and the support base 3 can be flexibly added as needed.

[0040] like Figures 1 to 11As shown, the connector 5 includes a fixed rod 504 and a sliding rod 507. There are multiple fixed rods 504 and sliding rods 507, and each fixed rod 504 and sliding rod 507 corresponds one-to-one with a groove 202. One end of the fixed rod 504 is connected to the fixed block 2. The sliding rod 507 slides inside the sliding groove 105. A rotating column 501 is threadedly connected to the outside of the fixed rod 504. The rotating column 501 rotates inside the groove 202 and is threaded into a threaded hole 104. A fixing ring 502 is provided on the outside of the rotating column 501. A threaded groove 506 is opened on the end of the rotating column 501 relative to the sliding rod 507.

The outer side of the sliding rod 507 is provided with a connecting plate 508 and a spring 509. The spring 509 is sleeved on the outer side of the sliding rod 507, and the connecting plate 508 slides inside the sliding groove 105. Specifically, when it is necessary to connect the heating seat 1, the fixing block 2 and the support seat 3, the heating seat 1, the fixing block 2 and the support seat 3 are first placed in sequence. After the placement is completed, the rotating column 501 is first rotated by the fixing ring 502. The rotating column 501 rotates along the fixed groove 105. The rod 504 moves relative to the threaded hole 104. While the rotating column 501 continuously engages with the threaded hole 104, the insert block 503 moves along the threaded groove 506, causing the fixing head 505 to insert into the insert block 503, thus achieving data connection. Simultaneously, the rotating column 501, in conjunction with the threaded hole 104, connects the fixing block 2 to the heating base 1 and the support base 3, ensuring the stability of the heating base 1, fixing block 2, and support base 3 during use. The fixing rod 504 and the rotating column 501 are connected by threads, and the thread pitch between the fixing rod 504 and the rotating column 501 is the same as the pitch of the internal thread inside the threaded hole 104. The threaded groove 506 has an internal thread... The insert 503 has an external thread on its outer side. During the rotation of the threaded groove 506, the insert 503 is pulled to move towards the rotating column 501 through the cooperation of the internal and external threads. The sliding rod 507 can be in the shape of a quadrangular prism, an elliptical prism, or a hexagonal prism. During the movement, the sliding rod 507 limits the insertion 503 to prevent the insertion 503 from rotating synchronously with the rotating column 501, ensuring the stability of the connection between the insertion 503 and the fixed head 505. After the insertion 503 is separated from the fixed head 505, the spring 509 and the connecting plate 508 provide the reset force for the insertion 503, so that the insertion 503 moves into the threaded hole 104.

[0041] like Figures 1 to 11As shown, the movable component 7 includes a support rod 701, which is connected to the control component 206. The support rod 701 has an internal mounting groove 703 and an external fixing frame 702. A connecting pipe 704 is slidably connected inside the fixing frame 702, and one end of the connecting pipe 704 is connected to the support rod 701. Specifically, the support rod 701 is connected to the telescopic end of the control component 206. During use, the support rod 701, in conjunction with the mounting groove 703, adjusts the position of the clamping component 6, thereby moving the crucible to different positions in conjunction with the threaded rod 204. During use, the connecting pipe 704, in conjunction with the fixing frame 702, provides power to the clamping component 6, ensuring the stability of the clamping component 6 during use.

[0042] like Figures 1 to 11 As shown, the clamping member 6 includes multiple mounting blocks 601, which slide within mounting grooves 703. Each mounting block 601 has a fixing post 609 on its side relative to the sliding block 205. Multiple guide grooves 602 are formed on the outer side of each mounting block 601. Contact blocks 606 and pressing blocks 603 are sequentially arranged within each guide groove 602.

A screw 607 is rotatably connected to the outer side of the pressing block 603. The mounting block 601 has a telescopic rod 608 inside. The telescopic end of the telescopic rod 608 slides inside the fixed post 609. The telescopic end of the telescopic rod 608 has a control block 610 and a moving block 611 in sequence. The control block 610 slides inside the fixed post 609. There are multiple moving blocks 611, and the moving blocks 611 slide inside the fixed post 609. The moving direction of the moving blocks 611 is perpendicular to the moving direction of the control block 610. The control block 610 has a control groove 614 on its outer side. A connecting strip 615 is slidably connected inside the control groove 614. Connected to the movable block 611, specifically, when it is necessary to cool down the heated crucible, firstly, the height of the fixed frame 702 is adjusted by the control component 206, so that the guide groove 602 moves out of the fixed block 2. Then, the support rod 701 is rotated by the control component 206, so that the guide groove 602 moves to the top of the crucible. Next, the guide groove 602 is moved into the crucible by the control component 206. After the guide groove 602 moves into the crucible, the movable block 611 is controlled by the telescopic rod 608 and the control block 610. 1. Slide outward to clamp the crucible. Finally, control the crucible to move from the placement rack 103 to the heat dissipation rack 302 for cooling through the control component 206 and guide groove 602. The screw 607 and the extrusion block 603 control the contact block 606 to contact and separate from the inner wall of the mounting groove 703, thereby limiting and adjusting the mounting block 601. The telescopic rod 608 can be electrically, pneumatically, or hydraulically controlled. During the movement of the mounting block 601, the moving block 611 can be controlled to expand outward or contract inward, thereby controlling the placement and removal of the crucible.

[0043] like Figures 1 to 11 As shown, a guide groove 612 is also provided on the outer side of the moving block 611. A guide block 613 is slidably connected inside the guide groove 612, and the guide block 613 is connected to the fixed post 609. Specifically, during the movement of the moving block 611, the moving block 611 is guided in the direction of movement by the cooperation of the guide block 613 and the guide groove 612, so as to avoid the moving block 611 tilting during the movement and ensure that the moving block 611 stably clamps the crucible. The moving block 611 is made of high temperature resistant material to ensure the stability of the moving block 611 in contact with the crucible.

[0044] like Figures 1 to 11 As shown, the heating base 1, support base 3, and fixing block 2 are all provided with fixing frames 101 on their outer sides. The fixing frames 101 are provided with fixing covers 4 and connecting covers 203 on their outer sides. The fixing covers 4 and connecting covers 203 are fitted onto the outer sides of the heating base 1, fixing block 2, and support base 3. Specifically, during use, the fixing covers 4 and connecting covers 203 work together to block the hot air generated during heating. Suction pipes can also be installed on the outer sides of the fixing covers 4 and connecting covers 203 as needed. The suction pipes are connected to the exhaust gas processor to collect the exhaust gas generated during use. The fixing frames 101 provide support for the fixing covers 4 and connecting covers 203 during use, ensuring the stability of the position of the fixing covers 4 and connecting covers 203 during use. The fixing covers 4 and connecting covers 203 are connected to the fixing frames 101 by snap-fit. A sealing gasket is also provided between the fixing covers 4 and connecting covers 203 to block the exhaust gas.

[0045] like Figures 1 to 11 As shown, the outer side of the fixing ring 502 has slots, and there are multiple slots. Specifically, during use, the slots are used in conjunction with tools to facilitate the control of the rotating column 501 and the fixing ring 502 to rotate in different directions.

[0046] like Figures 1 to 11 As shown, the extrusion block 603 is provided with a connecting groove 604 on the side opposite to the contact block 606. A connecting block 605 is slidably connected inside the connecting groove 604, and the connecting block 605 is connected to the contact block 606. Specifically, the connecting groove 604 and the connecting block 605 have the same shape. The connecting block 605 can be a T-shaped block or a dovetail-shaped block to ensure the stability of the position of the contact block 606 and the extrusion block 603 during use.

[0047] The modular graphite heating digestion apparatus operates as follows: After the crucible is heated, the height of the moving part 7 is first adjusted by the control component 206, causing the clamping part 6 to move out of the fixed block 2, preparing for subsequent clamping of the crucible. Then, the support rod 701 is rotated by the control component 206, moving the clamping part 6 to the top of the heated crucible, ensuring accurate alignment. Next, the clamping part 6 is moved into the crucible by the control component 206, placing it in a position to clamp the crucible. Once inside the crucible, the moving block 6 is controlled by the cooperation of the telescopic rod 608 and the control block 610. 11 slides outward to securely clamp the crucible. During the movement of the moving block 611, the guide block 613 and the guide groove 612 work together to guide the movement direction of the moving block 611, preventing it from tilting and ensuring the stability of the clamping. Finally, through the cooperation of the control component 206 and the clamping component 6, the clamped crucible is controlled to move from the placement rack 103 to the inside of the heat dissipation rack 302. After the crucible is placed, the moving block 611 is controlled to retract inward through the cooperation of the telescopic rod 608 and the control block 610, releasing the clamping of the crucible. At the same time, through the heat dissipation holes on the outside of the heat dissipation platform 301 and the fan, the airflow inside the heat dissipation platform 301 is controlled to accelerate the cooling speed.
