[0040] A driving column 23 is provided inside the support ring 18. The outer surface of the driving column 23 is rotatably connected to the inner wall of the support ring 18 through a bearing. A vortex track 24 is installed on the top of the driving column 23. The driving block 25 is located inside the vortex track 24. A measuring device 26 is placed on the top of the driving column 23, and the measuring device 26 is located between multiple groups of arc-shaped protective plates 22. Scale lines are provided on the surface of the measuring device 26. A first transmission gear 27 is installed at the bottom of the driving column 23, and a driving motor 28 is provided at the bottom of the base 1. The output end of the driving motor 28 is connected to the second transmission gear 29 through a coupling. The first transmission gear 27 is meshed with the second transmission gear 29. A supporting threaded rod 31 is provided above the output end of the telescopic rod 30. The bottom of the supporting threaded rod 31 passes through the output end of the telescopic rod 30, and multiple groups of stirring blades 32 are installed at intervals above the supporting threaded rod 31.

[0041] A secondary support plate 34 is fixed to one side of the main support 3, and a connecting shaft 35 is inserted through the secondary support plate 34. A first bevel gear 36 is installed at one end of the connecting shaft 35, and a rocker 37 is installed at the other end of the connecting shaft 35. A second bevel gear 38 is installed on the rotating shaft 4, and the first bevel gear 36 and the second bevel gear 38 are engaged with each other.

[0042] A protective pad is provided on the surface of the arc-shaped protection plate 22 to prevent the measuring device 26 from being damaged during use.

[0043] A positioning groove 39 is provided on one side of the rotating plate 19, and a second handle 40 is provided on one side of the base 1. A positioning pin 41 is connected to one side of the second handle 40. The end of the positioning pin 41 away from the second handle 40 extends into the positioning groove 39, and the sizes of the positioning pin 41 and the positioning groove 39 match each other.

[0044] The working principle of the present invention is as follows: when using the device, the connecting shaft 35 is driven to rotate by rotating the rocker 37. Under the transmission action of the first bevel gear 36 and the second bevel gear 38, the lifting threaded column 5 rotates accordingly, thereby achieving the purpose of adjusting the placement clamp 12. After the placement clamp 12 is adjusted, the first limiting column 7 can be driven to move by pulling the pull plate 9. When the first limiting column 7 comes out of the support groove 8, the position of the sliding sleeve 6 can be adjusted. When the position of the sliding sleeve 6 is adjusted, the pull plate 9 is released, and the sliding sleeve 6 is fixed under the action of the limit spring 10.

[0045] When it is necessary to fix the position of the measuring device 26, the driving motor 28 is turned on. Under the transmission action of the first transmission gear 27 and the second transmission gear 29, the driving column 23 rotates. When the driving column 23 rotates, it drives the vortex track 24 above it to rotate. Since the distance between the vortex line of the vortex track 24 and the center of the support ring 18 is constantly changing, the rotation of the vortex track 24 drives the driving block 25 to move. At this time, the three ejector rods 21 drive the arc-shaped protective plates 22 to approach each other, and finally fix the measuring device 26. At this time, the packing density of the activated carbon particles can be tested.

[0046] After measuring the packing density of the activated carbon particles, the telescopic rod 30 is opened, and its output end moves to drive the support threaded rod 31 to move to the top of the measuring device 26, and then the support threaded rod 31 is rotated to allow the stirring blade 32 to enter the inside of the measuring device 26. Then, an appropriate amount of water can be added to the inside of the funnel 44. At this time, the second handle 40 is pulled to drive the positioning pin 41 out of the through groove 42, and the drive motor 28 is turned on to drive the support ring 18 to rotate. When the support ring 18 rotates, it will drive the measuring device 26 to rotate. Since the stirring blade 32 and the measuring device 26 rotate relative to each other at this time, the activated carbon particles inside the measuring device 26 can be stirred. After the operation is completed, the water solubility of the activated carbon particles inside the measuring device 26 can be tested, and the staff does not need to stir the inside of the measuring device 26 again, thereby increasing the experimental speed.

[0047] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
