[0023] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a sampling device for liquor detection, including a test tube rack 1 for liquor detection and a test tube 2 placed in the test tube rack 1.

By providing the collection cylinder 3, the pressure plate 5, the rubber pad 6 and the pull rod 7, the function of liquor sampling is realized, and this sampling method does not need to be repeatedly screwed. The operation is relatively simple during sampling and disassembly, which is convenient for personnel to use. A docking tube 8 is fixedly sleeved on the outer surface of the pull rod 7, and a sleeve plate 9 is fixedly sleeved on the outer surface of the docking tube 8. By providing the docking tube 8 and the sleeve plate 9, it is convenient to assemble a group of docking tubes 8 and multiple collection cylinders 3, so that the sampling device can sample the same number of liquor samples according to the number of collection cylinders 3, which is convenient to use. Moreover, the setting of the sleeve plate 9 can increase the sealing performance of the docking between the docking tube 8 and the collection cylinder 3, preventing the pressure leakage in the collection cylinder 3 and the situation that liquor samples cannot be extracted, and improving the practicability of the device.

[0025] In the present invention, in order to improve the practicability of the device, the rubber pad 6 is set as a T-shaped pad, and a card slot for inserting the rubber pad 6 is opened on the outer surface of the pressure plate 5, so that the rubber pad 6 and the pressure plate 5 are tightly engaged, preventing the rubber pad 6 from detaching when the pressure plate 5 moves up and down. The wall thickness and inner diameter of the docking tube 8 and the collection cylinder 3 are the same, which is convenient for manufacturing the docking tube 8 and the collection cylinder 3. The height of the sleeve plate 9 is higher than the height of the docking tube 8, so that the sleeve plate 9 can cover the docking part of the docking tube 8 and the collection cylinder 3.

[0026] Please refer to Figures 1 - 3 , a collar 10 is adhesively bonded to the lower surface of the template 9. Two groups of arc-shaped blocks 11 are arranged inside the collar 10. A circular cylinder 12 is inserted inside the arc-shaped block 11. An extension rod 13 is slidably connected inside the circular cylinder 12. A fixing plate 14 is welded to the inner end of the extension rod 13. A spring 15 is arranged inside the circular cylinder 12, and the two ends of the spring 15 respectively abut against the inner wall of the circular cylinder 12 and the extension rod 13. A rotating ring 16 is adhesively bonded to the outer end of the circular cylinder 12. By providing the collar 10, arc-shaped blocks 11, circular cylinder 12, extension rod 13, fixing plate 14, spring 15 and rotating ring 16, it is convenient to fix the docking pipe 8 and the collection cylinder 3, so that the collection cylinder 3 remains stable when personnel take samples of white liquor. At the same time, the installation and disassembly of this component are relatively labor-saving. Only the rotating ring 16 needs to be rotated, the operation is simple and convenient, which is convenient for personnel to use. At the same time, the setting of the collar 10 can increase the contact range between the template 9 and the collection cylinder 3, making the assembly of the collection cylinder 3 more stable, and improving the stability of the sampling device.

[0027] In the present utility model, in order to improve the stability of the device operation, sliding grooves for the circular cylinder 12 to slide are opened inside the collar 10 and the arc-shaped blocks 11, so that the rotation of the circular cylinder 12 is not hindered. The height of the arc-shaped block 11 is the same as the height of the inner wall of the collar 10, so that the arc-shaped block 11 is more fittingly arranged inside the collar 10. A circular ring is fixedly sleeved at one end of the extension rod 13 inserted into the circular cylinder 12, which is convenient for the extension rod 13 and the circular cylinder 12 to abut against the spring 15, and the outer surface of the circular ring is in contact with the inner wall of the circular cylinder 12, so that the extension rod 13 slides stably inside the circular cylinder 12. The fixing plate 14 is an arc-shaped plate, which is convenient for the fixing plate 14 to clamp the arc-shaped collection cylinder 3. The radian of the inner side surface of the fixing plate 14 is the same as the radian of the inner diameter of the collar 10, so that the inner arc surface of the fixing plate 14 is in close contact with the outer surface of the collection cylinder 3.

[0028] When in use, when it is necessary to sample white liquor, insert the sampling head 4 into the white liquor, pull the pull rod 7 upward. The pull rod 7 drives the pressure plate 5 to move in the collection cylinder 3, and the pressure plate 5 drives the rubber pad 6 to move upward, thereby pumping the white liquor into the collection cylinder 3. And the height of the white liquor in the collection cylinder 3 should not exceed the collection cylinder 3. Insert the collection cylinder 3 into the test tube 2, rotate the rotating ring 16 clockwise. The rotating ring 16 drives the circular cylinder 12 to rotate, the circular cylinder 12 drives the extension rod 13 to rotate, and the extension rod 13 drives the fixing plate 14 to rotate, so that the fixing plate 14 contacts the thinner part of the arc-shaped block 11. The spring 15 contracts and pulls the extension rod 13 into the circular cylinder 12, and the extension rod 13 drives the fixing plate 14 to move outward, so that the fixing plate 14 no longer contacts the collection cylinder 3. The operator moves the docking pipe 8 upward, and the docking pipe 8 drives the sleeve plate 9 to be removed from the collection cylinder 3. The docking pipe 8 drives the pull rod 7 and the pressure plate 5 to move out of the collection cylinder 3, so that the collection cylinder 3 remains in the test tube 2, completing the sampling of white liquor. A set of collection cylinders 3 can be inserted into each set of test tubes 2, and each set of collection cylinders 3 can sample different types of white liquor, such as Maotai-flavor white liquor, light-flavor white liquor, etc. Then send the sampled white liquor to the laboratory for testing.

And this sampling method does not require repeated screwing, and the operation is relatively simple during sampling and disassembly, which is convenient for personnel to use. Through the setting of the test tube 2 and the collection cylinder 3, it is convenient for this sampling device to directly pump the white liquor into the collection cylinder 3. During subsequent testing, the white liquor can be directly taken out from the collection cylinder 3, which can reduce the operation steps of the testing personnel.

[0030] For the sampling device for white liquor detection, through the setting of the docking pipe 8 and the sleeve plate 9, it is convenient to assemble a set of docking pipes 8 and multiple sets of collection cylinders 3, so that this sampling device can sample the same number of white liquor samples according to the number of collection cylinders 3, which is convenient to use. And the setting of the sleeve plate 9 can increase the sealing performance of the docking between the docking pipe 8 and the collection cylinder 3, preventing the situation that the pressure in the collection cylinder 3 leaks and the white liquor sample cannot be pumped, improving the practicability of this device.

[0031] For the sampling device for white liquor detection, through the setting of the collar 10, the arc-shaped block 11, the circular cylinder 12, the extension rod 13, the fixing plate 14, the spring 15 and the rotating ring 16, it is convenient to fix the docking pipe 8 and the collection cylinder 3, so that the collection cylinder 3 remains stable when the operator samples white liquor.
