[0026] It should be noted that the connection between the sampling bottle 402 and the sampling tube 4 is provided with a sealing ring, and the operator needs to place the sampling bottle 402 in the inside of the sliding cup holder 501, and drive the sampling bottle 402 to slide into the inside of the sampling tube 4 by rotating the fixed handle 503. The sampling bottle 402 is fixed in the inside of the sampling tube 4 by the cooperation between the second threaded rod 502 and the fixed tube 5. The operator can move the plug tube 2 to the inside by rotating the sampling handle 302, so as to realize the intercommunication between the sampling tube 4 and the connecting tube 1, and then the sample liquid can be transported to the inner wall of the sampling bottle 402.

[0027] Specifically, the inner wall of the connecting tube 1 is provided with a connecting groove 102, the inner wall of the connecting groove 102 is slidably connected with the outer wall of the plug tube 2, the inner wall of the sampling tube 4 is provided with a sampling groove 401, the sampling groove 401 is connected with the connecting groove 102 in a penetrating manner, and the end of the sampling groove 401 away from the connecting groove 102 is sleeved with the top end of the sampling bottle 402.

[0028] It should be noted that the connecting groove 102 and the sampling groove 401 are mutually penetrated, the plug tube 2 is initially arranged at the end of the connecting groove 102, and the plug tube 2 can block the combination of the connecting groove 102 and the sampling groove 401. When the plug tube 2 slides away from the connecting groove 102 and the sampling groove 401, the sample liquid can flow into the sampling groove 401 through the connecting groove 102, and finally flow into the inner wall of the sampling bottle 402.

[0029] Specifically, the outer wall of the connecting tube 1 and the end close to the plug tube 2 are provided with a connecting flange 101, the end of the connecting tube 1 away from the connecting flange 101 is provided with a connecting cover 3, the end of the connecting cover 3 away from the connecting flange 101 is provided with a connecting ring 301, the inner wall of the connecting ring 301 is threadedly connected with the outer wall of the first threaded rod 202, the inner wall of the connecting tube 2 is provided with an inner thread 201, and the inner thread 201 is threadedly connected with the outer wall of the first threaded rod 202 and the end close to the connecting flange 101.

[0030] It should be noted that the operator needs to butt joint the connecting flange 101 to the flange plate of the reaction tank, and connect the connecting flange 101 by screws. When the operator rotates the sampling handle 302, the sampling handle 302 drives the first threaded rod 202 to rotate, and the first threaded rod 202 rotates in the inner wall of the connecting ring 301. The first threaded rod 202 is threadedly connected with the inner thread 201, and the inner thread 201 is displaced to the rotating position of the sampling handle 302 along the thread of the first threaded rod 202, so that the plug tube 2 is rotated and displaced on the outer wall of the first threaded rod 202, thereby realizing the intercommunication between the connecting groove 102 and the sampling groove 401.

[0031] Specifically, the outer wall of the sampling tube 4 is provided with an exhaust valve 403, the bottom end of the second threaded rod 502 is threadedly connected to the bottom end of the fixed tube 5, the sliding cup holder 501 is provided with a sliding block 505 at one end near the sampling bottle 402, the outer wall of the fixed tube 5 is provided with a sliding groove 504, and the inner wall of the sliding groove 504 is slidably connected to the outer wall of the sliding block 505.

[0032] It should be noted that when the operator rotates the fixed handle 503, the fixed handle 503 will drive the second threaded rod 502 to rotate. The second threaded rod 502 will engage with the bottom end of the fixed tube 5 through thread engagement. The second threaded rod 502 pushes the sliding cup holder 501 to slide through the thread engagement. The sliding cup holder 501 slides inside the sliding groove 504 through the sliding block 505, thus realizing the sliding of the sliding cup holder 501 inside the fixed tube 5.

[0033] Working principle of this utility model:

[0034] The specific operation is as follows: The operator needs to connect the connecting flange 101 of the connecting pipe 1 to the reaction vessel. Then, the operator needs to place the sampling bottle 402 onto the inner wall of the sliding cup holder 501. The operator can manually rotate the fixing handle 503, which will drive the second threaded rod 502 to rotate. The second threaded rod 502 will engage with the bottom end of the fixing pipe 5, causing the second threaded rod 502 to push the sliding cup holder 501 to slide. The sliding cup holder 501 will slide against the inner wall of the sliding groove 504 using the sliding block 505. The sliding cup holder 501 will drive the sampling bottle 402 to slide against each other, sliding the mouth of the sampling bottle 402 to the inner wall of the sampling groove 401. The sampling bottle 402 will be fixed in the sampling groove by the thread engagement between the second threaded rod 502 and the bottom end of the fixing pipe 5. The operator needs to rotate the sampling handle 302 on the inner wall of the sampling tank 401. The sampling handle 302 will drive the first threaded rod 202 to rotate. The outer wall of the first threaded rod 202 will continue to thread into the inner thread 201 of the plugging tube 2. The plugging tube 2 will rotate to the outer wall of the first threaded rod 202 during the threaded engagement, so that the sample liquid will flow from the connecting tank 102 to the inner wall of the sampling tank 401 along the movement trajectory of the plugging tube 2. The sample liquid then flows into the inner wall of the sampling bottle 402 through the sampling tank 401. When an appropriate amount of sample is taken out, the operator can rotate the sampling handle 302 in the opposite direction, so that the plugging tube 2 moves in the opposite direction and then plugs the connecting tube 1. Finally, the operator opens the exhaust valve 403 to release and adjust the air pressure. Finally, the sampling bottle 402 can be taken out.
