Clay particle extractor

Abstract

A clay particle extractor is disclosed, and comprises a water pump connected with a water tank and a cylinder vertically fixed on the water pump. A base disc provided with a water inlet is fixed at the lower end of the cylinder. A water inlet control sheet which rotates axially around the center of the bottom disc and is same with the bottom disc in structure is arranged below the bottom disc. A side tube inclining downward is arranged on the upper side surface of the cylinder and connected with an extraction and filtration device of a vacuum pump. A switch controller of the water pump can be installed on the water inlet control sheet and the cylinder can be a glass cylinder which is convenient to process and use. The invention has a simple and reasonable structure, is convenient to operate and has low cost. When the clay particle extractor is used, the clay particle extractor is good in controllability, has less manual influencing factors, remarkably reduces the time and procedure to extract the clay particles, improves the separation degree of the clay particles, and effectively solves the deficiencies of cockamamie steps, long time consumed, large manpower consumption, low separation degree of clay particles in prior art, thereby providing reliable data for further study on sequent mineral particles of clay.

Description

technical field [0001] The invention relates to a clay particle extracting device, which is used for separating soil particles with different particle sizes in sediments. Background technique [0002] Clay minerals are widely distributed in surface sediments. Because of their particularity in structure, crystal structure, chemical composition and physical and chemical properties, clay minerals play an important role in scientific research. Climate, accounting for environmental evolution, etc. are of great significance. In order to analyze the composition, content and chemical composition of clay, it is necessary to separate and extract the clay particles. Therefore, the separation and extraction of clay particles is the basis of related research, and the quality of clay separation will directly affect the analysis and measurement results. [0003] Regarding the separation and extraction methods of clay particles, the sedimentation siphon separation method and centrifugal s...

Problems solved by technology

[0004] The sedimentation siphon separation method has a clear principle and clear steps, and is widely used. However, if you want to separate the clay particles thoroughly and extract the particle size accurately, this method still has obvious shortcomings, mainly in the following: cumbersome operation steps and time required for complete separation Longer, after each extraction, it is necessary to add an equal amount of distilled water to the beaker, and then stir and settle to extract, so repeated many times; external and human factors are greatly affected, such as clay suspension concentration, temperature, extraction depth and time, etc. Both will affect the clay separation results; in addition, when the siphon is placed in the beaker, it will stir the surrounding suspension and disturb the settled coarse particles, reducing the extraction accuracy

The centrifugation method is fast and time-consuming, but the centrifugation speed and centrifugation time corresponding to the particle size to be extracted are not easy to control, which makes this method subject to many limitations in practical application.
