As shown in FIGS. 1 to 4, the micro-moisture meter according to the present invention comprises a base 10, wherein the base 10 is provided with a control box 20, an electrolytic cartridge 30 and a meter body 40. The top of the electrolytic cylinder 30 is provided with a cover plate 31, the bottom of the electrolytic cylinder 30 is provided with a liquid outlet pipe 32 communicated with the inside of the electrolytic cylinder, and the liquid outlet pipe 32 is provided with a valve 33. A moisture detection probe 41 is attached to one side of the measuring instrument body 40, and the moisture detection probe 41 extends into the electrolytic cartridge 30. The above are all the prior art, and the detailed structure is not described herein.

The present invention also includes a stirring assembly 50 and a motor 60. The stirring assembly 50 is disposed in the electrolytic cell 30, and the stirring assembly 50 includes a rotating disk 51, a guide post 52, and a sleeve 53. The rotating disc 51 is arranged along the transverse direction and is rotatably connected with the base 10 through a rotating shaft 54; specifically, the rotating shaft 54 is disposed along the longitudinal direction, the upper end of the rotating shaft 54 is fixedly connected to the bottom of the rotating disc 51, and the lower end of the rotating shaft 54 is rotatably connected to the base 10 and maintains a seal. The guide post 52 is disposed along the longitudinal direction and fixedly connected to the top of the rotating disc 51, and a screw hole 521 extending downward is formed at the top of the guide post 52. The sleeve 53 is sleeved on the guide post 52 and is connected with the guide post 52 in a sliding manner. The side walls of the two sides of the sleeve 53 are respectively provided with a first paddle 55 and a second paddle 56, and the second paddle 56 is positioned below the first paddle 55. The top of the sleeve 53 is also provided with a screw 57, and the threaded end of the screw 57 can pass through the sleeve 53 and then match with the threaded hole 521 at the top of the guide post 52. The motor 60 is disposed at the bottom of the base 10 and electrically connected to the control box 20, and the motor 60 is used for driving the rotation shaft 54 to rotate.

The specific working process is as follows: in use, a worker introduces Karl Fischer's reagent into the electrolytic cell 30. Then the control box 20 controls the motor 60 to work, and the motor 60 drives the sleeve 53 to rotate through the rotating shaft 54, the rotating disc 51 and the guide column 52, so that the first blades 55 and the second blades 56 on two sides of the sleeve 53 stir the liquid in the electrolytic cylinder 30, and the reaction rate is increased. The moisture detection probe 41 transmits the detected moisture data to the control box 20 and the meter body 40 for processing and display.

When the stirring assembly 50 is cleaned after the work is finished, the worker opens the valve 33 to discharge the liquid in the electrolytic tank 30, and then opens the cover plate 31 and screws 57 at the top of the sleeve 53. At this time, the sleeve 53 is separated from the guide post 52, and after the worker takes out the sleeve 53, the first blade 55 and the second blade 56 can be cleaned, which is very convenient.

In one embodiment, an adjusting assembly 70 is disposed on each side of the casing 53, and the adjusting assembly 70 includes a guide rod 71, a bidirectional screw 72, a first slider 73 and a second slider 74. The guide column 52 and the bidirectional screw 72 are both arranged along the longitudinal direction, both ends of the guide column 52 are both fixedly connected with the sleeve 53, and both ends of the bidirectional screw 72 are both rotatably connected with the sleeve 53. The first slider 73 and the second slider 74 are respectively disposed at upper and lower ends of the guide bar 71 and are both slidably connected to the guide bar 71. The first slider 73 and the second slider 74 are also respectively in threaded connection with the upper and lower ends of the bidirectional screw 72. The first paddle 55 and the second paddle 56 are fixedly mounted on the first slider 73 and the second slider 74, respectively.

Since the screw threads at both ends of the bidirectional screw 72 are opposite in spiral direction. Therefore, when the worker rotates the two-way screw 72, the first slider 73 and the second slider 74 move closer to or away from each other by the guide bar 71, and the first paddle 55 and the second paddle 56 fixedly mounted on the first slider 73 and the second slider 74 move closer to or away from each other simultaneously. The design enables a worker to adjust the distance between the first blade 55 and the second blade 56 according to actual needs, and meets more use requirements of the worker.

In one embodiment, the first and second paddles 55, 56 are both obliquely disposed. This can make the first paddle 55 and the second paddle 56 stir the liquid in the electrolytic canister 30 better.

In one embodiment, the first blade 55 and the second blade 56 are both provided with a plurality of flow guiding holes 58 therethrough. When the first blade 55 and the second blade 56 stir the liquid in the electrolytic cartridge 30, a part of the liquid can pass through the diversion hole 58, so that the resistance of the first blade 55 and the second blade 56 during stirring is smaller, and the operation of the stirring assembly 50 is smoother.

In one embodiment, a handle 75 is installed at the upper end of the bidirectional screw 72, and the worker can control the rotation of the bidirectional screw 72 through the handle 75, which is very convenient.
