[0047] The side plate 11 is fixed to the top surface of the bottom plate 9, and the side plate 11 is perpendicular to the bottom plate 9;

[0048] The slide rail 12 is vertically fixed to one side of the side plate 11, and a vertically arranged mounting groove is provided on a side of the slide rail 12 away from the side plate 11;

[0049] The rack 13 is fixed in the mounting groove;

[0051] The adjusting rod 8 horizontally passes through the slide 14 . A gear is coaxially fixed to the adjusting rod 8 . The gear is arranged in the vertical groove and meshes with the rack 13 .

[0052] According to a further optimized solution, a locking bolt 6 is threadedly connected to one side of the slide 14 away from the adjusting rod 8 , and a threaded end of the locking bolt 6 passes through the slide 14 and abuts against a side wall of the slide rail 12 .

[0053] To further optimize the solution, the lighting department includes:

[0054] The light source buckle 7 is detachably connected to the hole 5 via a plurality of first short rods;

[0055] The light source 2 is detachably connected to a side of the light source buckle 7 away from the slide 14 .

[0065] One specific example:

[0066] The slurry 3 is placed in a light-transmitting container 1, and the light-transmitting container 1 is embedded on a bottom plate 9 and located between a light meter 4 and a light source 2, wherein the light source 2 and the light meter 4 are located at the bottom end of a slide 14;

[0067] The light-transmitting container 1 must meet the requirements of a net width of not less than 5d, a length of not less than 50mm, a height of not less than 100mm, and a light transmittance of more than 80%.

[0068] After the slurry is stable (or after a set time, depending on the test requirements), start the light source 2 and the photometer 4, the light source 2 irradiates the light-transmitting container 1, the photometer 4 receives the laser transmitted by the light-transmitting container 1 and displays the laser intensity, and records the data; by rotating the adjusting rod 8, the adjusting rod 8 drives the gear to rotate, and then drives the slide 14 to move up. After reaching the set position, rotate the locking bolt 6 to fix the slide 14, continue to irradiate the light-transmitting container 1 with the light source 2, the photometer 4 receives the laser transmitted by the light-transmitting container 1 and displays the laser intensity, repeat multiple times, and measure the stability of the slurry through statistical data.

[0069] The evaluation and determination of stability can be done by a variety of calculation methods. Calculation method 1: Divide the illuminance readings at each point at different static settling times by the initial illuminance value at each point, that is, I = P i t / P i 0, the larger the reform, the more obvious the settlement stratification; calculation method 2, the illuminance readings at each point at different static settlement times are divided by the illuminance value of the bottom measuring point, that is The larger the value, the more obvious the sedimentation stratification. Of course, in practice, other quantitative methods can also be defined using the measured light intensity.

[0070] Where: I is the illumination ratio (dimensionless). The larger the value, the more serious the sedimentation of particles inside the slurry and the worse the stability; P i t Illuminance at measuring point i at time t, unit: Lux; P i 0 The initial illuminance at measuring point i, in Lux; The illuminance at the bottom measuring point i at time t, in Lux. It is recommended to use calculation method 1 for calculation and evaluation.

[0071] Evaluation of slurry stability: In actual evaluation, three measuring points (measuring points 1, 2, and 3) can be selected, and the slurry stability can be evaluated by the ratio of the illuminance values ​​of the two measuring points to the illuminance value of the bottom measuring point; that is, I1 t =P1 t / P1 0 , Of course, in actual measurement, more measuring points can be predetermined along the height of the container according to actual conditions, and the stratification of the measured slurry can be obtained.
