The slide bar 10 extends outside the diverter box 2 and connects to a runner 11. A connecting block 12 is fixedly mounted on the outer wall of the slide bar 10 outside the diverter box 2. A spring 13 is mounted on one side of the connecting block 12 and on the outer wall of the slide bar 10. A symmetrically arranged limit block 14 is mounted on the outer wall of the runner 11. A limit bracket 15 is attached to one side of the diverter box 2 to match the limit block 14. A sliding hole 1 is provided in the diverter box 2 to match the slide bar 10. The runner 11 is connected to the slide bar 10 via a bearing. The connecting block 12 is connected to the diverter box 2 via a spring 13. When sampling and testing, a group of wheels 11 are rotated, and the wheels 11 drive the limit block 14 to disengage from the limit frame 15. At this time, the spring 13 starts to reset and drives the slide bar 10 to move to the outside of the diversion box 2. The slide bar 10 drives the block 9 to move in the control groove 4. At this time, the sampling tube 3 is connected with the delivery pipe 1 6, and the pressure control component is started to make the pressure in the extraction box 5 lower than the pressure in the reactor 1. Therefore, the liquid in the reactor 1 is transported to the delivery pipe 2 8 corresponding to the extraction box 5 through the sampling tube 3 and the delivery pipe 1 6, and enters the detection device 7 for detection in an emergency. When sampling is performed in the next time period, the previous group of opened sampling tubes 3 are first closed and the other sampling tube 3 is opened. The steps are as above. By setting the interception component, different sampling tubes can be used for sampling and testing in different time periods to prevent residual liquid in the sampling tube from affecting the accuracy of subsequent sampling and detection.

[0030] like Figure 1-7As shown, it includes a reactor 1, a diverter box 2 is provided on one side of the reactor 1, and a plurality of evenly distributed sampling tubes 3 are provided on the top of the diverter box 2. One side of the sampling tubes 3 extends into the reactor 1. A plurality of evenly distributed control slots 4 are provided in the diverter box 2. The sampling tubes 3 are connected to the control slots 4. The control slots 4 are provided with a cut-off assembly. An extraction box 5 is provided at the bottom of the diverter box 2. A plurality of evenly distributed delivery tubes 6 are provided on the top of the extraction box 5 and are respectively connected to the control slots 4.

A detection device 7 is provided at the bottom of the extraction box 5. A plurality of evenly distributed delivery tubes 8 are provided on the top of the detection device 7 and are respectively connected to the extraction box 5. The pressure control assembly includes a vacuum pump 16 provided on each side of the extraction box 5 and connected thereto. The vacuum pump 16 is provided with a matching piston 17. A connecting rod 18 is provided on one side of the piston 17. One side of the connecting rod 18 extends outside the extraction box 5 and is connected to the drive assembly. A second sliding hole is provided on one side of the vacuum cylinder 16 to match the connecting rod 18. The drive assembly includes a drive box 19 provided on one side of the extraction box 5. The drive box 19 is provided with a dual-axis motor 20. A screw 21 is provided on each driving end of the dual-axis motor 20. A movable sleeve 22 is sleeved on the outer wall of the screw 21. One side of the connecting rod 18 extends into the drive box 19 and is connected to the movable sleeve 22. A third sliding hole is provided on one side of the drive box 19 to match the connecting rod 18. A threaded groove is provided on the inner wall of the movable sleeve 22 to match the screw 21. A symmetrical guide block 23 is provided on the outer wall of the movable sleeve 22. A travel groove 24 is provided on the inner wall of the drive box 19 to match the guide block 23. When controlling the pressure in the extraction box 5, first start the dual-axis motor 20 to drive the two sets of screw rods 21 to rotate. The screw rods 21 drive the movable sleeve 22 to move to the side away from the dual-axis motor 20. The movable sleeve 22 drives the piston 17 to move through the connecting rod 18. By setting up a pressure control component, the piston can be pulled to both sides at the same time, so the pressure difference between the reactor and the extraction box can be quickly changed, thereby speeding up the sampling speed.

[0031] In actual application, when sampling and testing is carried out, a group of wheels 11 are rotated, and the wheels 11 drive the limit block 14 to disengage from the limit frame 15. At this time, the spring 13 starts to reset and drives the slide bar 10 to move to the outside of the diversion box 2. The slide bar 10 drives the block 9 to move in the control groove 4. At this time, the sampling tube 3 is connected with the delivery pipe 1 6, and the pressure control component is started to make the pressure in the extraction box 5 lower than the pressure in the reactor 1. Therefore, the liquid in the reactor 1 is transported to the corresponding delivery pipe 2 8 on the extraction box 5 through the sampling tube 3 and the delivery pipe 1 6, and enters the detection device 7 for detection in an emergency. When sampling is carried out in the next time period, the previously opened sampling tube 3 is first closed, and the opened sampling tube 3 is opened. For another sampling tube 3, the steps are as above. By setting up a cut-off component, different sampling tubes can be used for sampling and testing at different time periods to prevent residual liquid in the sampling tube from affecting the accuracy of subsequent sampling and testing. At the same time, the cut-off component is simple to operate and easy to use through the cooperation of the spring and the block; when controlling the pressure in the extraction box 5, first start the dual-axis motor 20 to drive the two sets of screw rods 21 to rotate, and the screw rods 21 drive the movable sleeve 22 to move to the side away from the dual-axis motor 20. The movable sleeve 22 drives the piston 17 to move through the connecting rod 18. By setting up a pressure control component, the piston can be pulled to both sides at the same time, so the pressure difference between the reactor and the extraction box can be quickly changed, thereby speeding up the sampling speed.

[0032] To sum up, with the help of the above-mentioned technical solution of the present invention, by setting up the interception component, different sampling tubes can be used for sampling and testing at different time periods to prevent the residual liquid in the sampling tube from affecting the accuracy of subsequent sampling and testing. At the same time, the interception component is simple to operate and easy to use through the cooperation of the spring and the block. By setting up the pressure control component, the piston can be pulled to both sides at the same time, so the pressure difference between the reactor and the extraction box can be quickly changed, thereby speeding up the sampling speed.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
