[0040] The method for using the device for detecting the mud content of sand and soil can be performed by the following steps:

[0041] Weigh the mass of the filter device 20 as M1, and weigh the total mass of the filter device 20 and the sand and soil as M2; connect the cover 1 22 to the filter cylinder 21 through threads, put an appropriate amount of dried sand and soil into the filter cylinder 21, the volume of which cannot exceed one quarter of the volume of the filter cylinder 21, and then connect the cover 2 24 to the filter cylinder 21 through threads;

[0043] Connect the power plug 51, start the electric motor 31, open the valve 2 17 after the filter device 20 rotates for 20 minutes, and when the water level drops to half, open the valve 15 and the valve 3 43 again to wash the sand and soil, observe the pressure gauge 19, and the pressure of the pressure water can be controlled by adjusting the valve 15. When the water discharged from the drain pipe 16 is clear, close the valve 15 and the valve 3 43, turn off the power plug 51, take out the filter device 20, put it in the oven for drying, and weigh the total mass of the filter device 20 and the remaining sand and soil after drying as M3;

[0044] The mud content of sand can be calculated by the following formula:

[0045]

[0046] Wherein, w is the mud content of sand; M1 is the mass of the filter device 20; M2 is the total mass of the filter device 20 and the initial sand; M3 is the total mass of the filter device 20 and the sand after flushing.

[0047] Through the above scheme, the detection of sand content is simple and efficient. On the one hand, it avoids the splashing and loss of sand samples during the cleaning and flushing of sand samples; on the other hand, it reduces the labor intensity of experimenters; further, it avoids unclean sand flushing due to manual labor. The equipment flushes thoroughly and can achieve accurate test results.

[0048] In order to ensure the strength of the filter cylinder 21, stainless steel can be used; and in order to effectively flush out muddy water, the wall thickness of the filter cylinder cannot be set too thick, and the filter aperture should be set to 0.075mm; considering the wear of the filter cylinder 21, the filter cylinder 21 can be replaced according to actual conditions.
