Manual salt-retention water-retention fidelity sampling device and use method thereof

Abstract

The invention belongs to the field of salt lake collection device and particularly relates to a manual salt-retention water-retention fidelity sampling device and a use method thereof. The device comprises a hollow cylindrical sampling outer bin, a hollow outer cone is arranged on the lower end face of the sampling outer bin, a sampling inner bin is arranged in the sampling outer bin, an inner cone is arranged in the outer cone, a rotary bearing is disposed between the inner wall of the sampling outer bin and the outer wall of the sampling inner bin, sample inlets are formed in the outer cone and the inner cone, sampling ports are formed in the cylindrical face of the sampling outer bin and the cylindrical face of the sampling inner bin, a horizontal partition board is arranged in the sampling inner bin, and ventilation and water passing holes are formed in the horizontal partition board. An outer hollow pipe is arranged on the top of the sampling outer bin, an inner hollow pipe is arranged on the top of the sampling inner bin, a rotary bearing is arranged between the outer wall of the inner hollow pipe and the inner wall of the outer hollow pipe, a rotary handle is arranged on the outer wall of the top of the inner hollow pipe, and a fixed extraction handle is arranged on the outer wall of the top of the outer hollow pipe. The device is small in disturbance during sampling, and sample fidelity is high.

Description

technical field [0001] The invention belongs to the field of salt lake collection devices, and in particular relates to a manual salt-locking water-locking fidelity sampling device and a use method thereof. Background technique [0002] To establish a three-dimensional digital model of the salt drying process and mineralization under brine, it is necessary to analyze the composition of crystallized salt precipitated under brine at each time period. After purchasing corresponding equipment, consulting many literatures and actual sampling and analysis experiments, it is found that it is not easy to achieve fidelity sampling. Sediment sampling analysis under water (liquid) can not only have good detection and guiding significance for the industrial production of potassium sulfate, but also can be used for the weathering and denudation of rocks and soil in water sources such as rivers and reservoirs, and the causes of environmental pollution around water bodies. is of great sig...

AI Technical Summary

Problems solved by technology

[0004] (1) These two sampling devices are placed with ropes, which are not easy to operate and locate;

[0005] (2) These two sampling devices are relatively heavy and must be operated by multiple people or mechanically lifted;

[0006] (3) After the grab sampler collects the sediment, it is washed by the water flow during the lifting operation, the sample loss is disturbed, and it is easy to be polluted, resulting in the distortion of the collected sample data;

[0007] (4) The cumbersome gravity sinking sampler cannot operate at all for the sediment collection in the shoal here in the salt field
