Embodiment Construction

[0020] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0021] Such as figure 1 A pressurized saline soil desalination device is shown, including a water supply tank 1, a pressure pump 3 and a sample tank 14, and the water supply tank is filled with deionized water. The lid of the water supply bucket includes a cover body 5 and a sealing rubber pad between the lid body and the water supply bucket bucket body. The hook 4 adapted to the slot is inserted into the slot by the hook to fix the lid and the barrel, and a good seal is ensured by the provided sealing rubber pad. The cover body is provided with an air inlet 6, and the air inlet 6 communicates with the air outlet of the pressurizing pump 3 through an air inlet pipe, which is a high-pressure rubber hose and is connected to the cover body.

[0022] A liquid level gauge 2 is installed on the outer wall of the water supply ba...

Abstract

The invention relates to a pressure type salty soil desalter, comprising a water supply bucket communicated with a pressure pump by virtue of an air inlet pipe and a sample bucket provided with a detachable top cover, the bottom of the sample bucket is communicated with the water supply bucket by virtue of a water inlet pipe, a lower filter layer, salty soil and an upper filter layer are sequentially arranged from bottom to top in the sample bucket, and a water outlet pipe communicated with the interior of the sample bucket is arranged on a top cover of the sample bucket. The pressure type salty soil desalter provided by the invention not only can realize desalting treatment on all kinds of salty soil but also can study influence of water pressure on a soil mass desalting process by regulating output pressure of the pressure pump; rules that salt content of soil mass changes over time can be summarized according to measured conductivity values; filtering effect of porous stones, a filter screen or filter paper is skillfully utilized, soil particle loss is reduced, influence of a test on size distribution of soil particles is reduced, and accuracy of the test is improved; and the pressure pump is utilized for pressurization, thus not only a test period can be greatly shortened, but also the aim of saving water can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil testing, in particular to a pressurized saline soil desalination device. Background technique [0002] According to statistics, 2% of my country's land area belongs to saline soil, 20% of cultivated land has different degrees of salinization and secondary salinization, and 260 million mu of land is threatened by potential salinization. In this context, domestic research on saline soil is increasing day by day, and its research scope has gradually expanded to many fields, such as: agricultural engineering, civil engineering, physical geography, etc. [0003] People often define different saline soils according to the difference in salinity in the soil, and the difference in salinity also affects the material properties of the soil. Taking geotechnical engineering research as an example, in order to study the influence of salt on the mechanical properties of soil, the test soil must first be desalinat...
