Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a silt particle size analyzer comprises a base 1 and a mounting plate 2 fixed on the base 1, wherein a peristaltic pump 3, an electronic scale 4, a settling chamber and a liquid discharge chamber 6 are fixedly mounted on the mounting plate 2 through bolts, a scale pan 7 is arranged on the electronic scale 4, a spiral flow guide pipe 8 is fixed on the scale pan 7, the settling chamber discharges liquid through the liquid discharge chamber 6, and a liquid inlet pipe 12 is arranged at an inlet of the peristaltic pump 3 to extract a water flow sample. The utility model discloses a peristaltic pump 3 extracts a certain amount of rivers sample, and the sample flows into the deposit room through spiral honeycomb duct 8 again and subsides.

The mass of the spiral flow guide pipe 8 is weighed by an electronic scale in the process that the sample passes through the spiral flow guide pipe 8, and the accumulation of the mass variation of the spiral flow guide pipe 8 is the volume weight of the water flow sample. Because the vibration force generated by the peristaltic motion of the peristaltic pump 3 can be transmitted to the spiral flow guide pipe 8 through a pipeline, and further the measurement of the electronic scale 4 is influenced, so that the data accuracy is reduced, in order to reduce the volume weight measurement error, the upper end of the spiral flow guide pipe 8 is communicated with the outlet of the peristaltic pump 3 through the hose 9, and the transmission of the vibration force is weakened through the hose 9 so as to reduce the measurement error brought to the electronic scale 4 by the peristaltic pump 3.
