[0027] Specifically, Figure 1 As shown, a rubber pad 12 is fixedly connected to the lower surface of the support plate 1. The rubber pad 12 increases the friction between the device and the desktop, so that the device can be placed stably.

[0028] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the blocking mechanism 5 includes a threaded rod 51 rotatably connected to the inner surface of the slide plate 2, one end of the threaded rod 51 is fixedly connected to a rotating block 52, the outer surface of the threaded rod 51 is equidistantly threadedly connected to a plurality of blocking plates 53, the plurality of blocking plates 53 are all in contact with the slide plate 2, the inner surfaces of the plurality of blocking plates 53 are slidably connected to a limiting rod 54, the limiting rod 54 is fixedly connected to the slide plate 2, the outer surface of the limiting rod 54 is equidistantly fixedly connected to a positioning block 55, the positioning block 55 is in contact with the blocking plate 53.

[0029] When discharging the solution, the rotating block 52 is rotated, and the threaded rod 51 is driven to rotate by the rotating block 52, and then the blocking plate 53 is driven to move and separate from the slide plate 2 by the rotating threaded rod 51, so as to release the blocking state of the liquid outlet 3, and the solution in the solid phase extraction column 4 can be discharged through the liquid outlet 3. After the discharge is completed, the rotating block 52 is reversed, and the threaded rod 51 is driven to reverse by the rotating block 52, and then the blocking plate 53 is driven to return to its original position by the reverse rotation of the threaded rod 51, so as to block the liquid outlet 3. In this process, the blocking plate 53 is stably moved by the limiting rod 54, and is positioned by the positioning block 55;

Through the cooperation of the threaded rod 51, the rotating block 52, the blocking plate 53, the limit rod 54 and the positioning block 55, the multiple liquid outlets 3 can be synchronously blocked or unblocked, which saves time and effort, facilitates the discharge of the solution, and improves the extraction efficiency of methamphetamine in sewage.

After the slide plate 2 contacts the other fixed block 74, the other fixed block 74 moves up. When the slide plate 2 moves to a certain position, the elastic force of the spring 73 causes the connecting plate 72 to move down, and then the fixed block 74 moves down and plugs into the slot 6 on the slide plate 2, so that the slide plate 2 moved to a certain position is positioned and fixed, and then subsequent activation, sample loading, rinsing, elution and other vehicle operations can be carried out.

[0036] Specifically, Figure 1 and Figure 2As shown, the liquid adding mechanism 8 includes an activation solution tank 81, a sewage tank 82, a spray solution tank 83, and an elution solution tank 84 which are fixedly connected to the upper surface of the support plate 1; the lower surfaces of the activation solution tank 81, the sewage tank 82, the spray solution tank 83, and the elution solution tank 84 are symmetrically and fixedly connected with a plurality of liquid outlet pipes 85; the plurality of liquid outlet pipes 85 are fixedly connected to the support plate 1; and the outer surfaces of the liquid outlet pipes 85 are fixedly connected with valves 86.

[0037] When the solid phase extraction column 4 moves to the bottom of the activation solution tank 81, the valve 86 on the liquid outlet pipe 85 connected to the activation solution tank 81 is opened, and the activation solution in the activation solution tank 81 can be discharged through the liquid outlet pipe 85, and the activation solution is quantitatively added. When the solid phase extraction column 4 moves to the bottom of the sewage tank 82, the valve 86 on the liquid outlet pipe 85 connected to the sewage tank 82 is opened, and the sewage in the sewage tank 82 can be discharged through the liquid outlet pipe 85, and the sewage is quantitatively added. When the solid phase extraction column 4 moves to the bottom of the spray solution tank 83, the valve 86 on the liquid outlet pipe 85 connected to the spray solution tank 83 is opened, and the spray solution in the spray solution tank 83 can be discharged through the liquid outlet pipe 85, and the spray solution is quantitatively added.

At this time, the valve 86 on the liquid outlet pipe 85 connected to the activation solution tank 81 is opened, and the activation solution in the activation solution tank 81 can be discharged through the liquid outlet pipe 85, and the activation solution is quantitatively added. After the activation of the chemical adsorbent is completed , rotate the rotating block 52, and the threaded rod 51 is driven to rotate by the rotation of the rotating block 52, and then the sealing plate 53 is driven to move and separate from the slide plate 2 by the rotation of the threaded rod 51, so as to release the blocking state of the liquid outlet 3, and the solution in the solid phase extraction column 4 can be discharged through the liquid outlet 3, and then the discharged waste liquid is collected through the waste liquid collection box 9. After the waste liquid is discharged, the rotating block 52 is reversed, and the threaded rod 51 is reversed by the rotation of the rotating block 52, and then the sealing plate 53 is restored to its original position by the reversal of the threaded rod 51, so as to block the liquid outlet 3. In this process, the sealing plate 53 is stably moved by the limit rod 54, and is positioned by the positioning block 55. After activation, loading, rinsing, elution and other operations are performed in sequence, the extracted methylpropylamine can be collected through the test tube 11.
