Automatic device for obtaining soil turbid liquids with different particle sizes by sedimentation derivation method

Technical Field

The utility model relates to a soil particle draws the field among agronomy, ecology, the environmentology, concretely relates to subsides automation equipment that derives the method and acquire different particle diameter soil turbid liquid.

Background

The physical and chemical properties of the soil particle components with different particle sizes have obvious difference, and meanwhile, the soil particle components also have great influence on the research of agriculture and environment, and are important contents of the scientific research of soil. Therefore, it is very important to independently research the physicochemical properties of the soil particles with different particle sizes, and the required amount of the soil particle samples with different particle sizes in the research is often large, so that the rapid and accurate acquisition of sufficient soil particles with various particle sizes is an important prerequisite for the subsequent soil particle property analysis. At present, the common clay particle separation methods are mainly a sedimentation siphon separation method and a centrifugal separation method. Both the two methods are carried out on the basis of the Stokes principle, which means that dispersed particles uniformly distributed in a medium can be settled under the action of gravity, when the gravity and the resistance (viscosity coefficient of the medium) reach a balance, the dispersed particles are settled at a constant speed, and the settling rate of the particles is in direct proportion to the square of the radius of the particles and in inverse proportion to the viscosity coefficient of the medium.

The settling siphon separation method is that a soil turbid liquid sample is transferred into a settling barrel, soil particles are uniformly distributed in water by stirring, then the soil particles are allowed to freely settle, the settling rates of the soil particles with different particle sizes are different under the influence of gravity and viscous resistance of water, the required time for settling the soil particles with different particle sizes in a certain depth is calculated according to the Stokes law, the soil turbid liquid with the depth more than a certain time is sucked out by a siphon, and the soil particles with the required particle sizes are obtained after drying. After each extraction, adding equal amount of distilled water into the settling tank, and repeatedly extracting for many times until the suspension is no longer turbid, i.e. the liquid in the extraction depth range is clear liquid. Although the sedimentation siphon separation method has simple steps and convenient operation, the siphon tube needs to be held by one hand, and the suspension absorbing process is easily influenced by human factors, so that the position for absorbing the suspension is not accurate, and soil particles with different particle sizes cannot be accurately and thoroughly separated; and the soil clay sample amount that sedimentation siphon separation method single extracted is few, when needing a large amount of samples, and it is long, the efficiency is lower to extract repeatedly consuming time.

The centrifugal separation method is a method for separating clay by using a centrifuge. The dispersed particles inevitably move to the bottom of the tube due to the centrifugal force. The faster the centrifuge is rotated, the stronger the centrifugal force on the dispersed particles and the faster the settling rate. In the clay suspension, the large clay particles settle fast and the small clay particles settle slowly because the large clay particles are subjected to a larger gravity than the small clay particles. If the centrifugal force is used instead of the gravity, the dispersed particles of different particle sizes can be separated by changing the rotation speed and the centrifugation time of the centrifuge according to the Stokes sedimentation rule. The most important advantages of clay separation by centrifugation are high speed and short time, but the fixed centrifuge condition is not easy to satisfy, and the centrifugal speed and centrifugal time of the particle fraction to be extracted are not easy to control, so that the method is not widely used.

At present, the efficiency and the separation purity of the two commonly used soil particle size screening technologies need to be improved, and an automatic instrument which is simple, flexible, efficient and accurate and reduces the workload is lacked.
