Device and method for quickly dispersing sand grains

Abstract

The invention discloses a device and a method for quickly dispersing sand grains. The device comprises a stirring cylinder, a micro pipeline pump and a dispersing bin; stirrers are arranged in the stirring cylinder, and a dispersing plate and a barrier glass plate are sequentially arranged above the dispersing bin; the method comprises the following steps of: adding the sand grains into the stirring cylinder into which liquid nitrogen is filled, and fully mixing the sand grains and the liquid nitrogen under the action of the stirrers; inputting mixed liquid into the dispersing bin by the micro pipeline pump and returning the mixed liquid to the stirring cylinder along a connection pipeline; and after the mixed liquid circulates between the dispersing bin and the stirring cylinder for a certain period of time, closing electric valves at two ends of the micro pipeline pump and the dispersing bin, opening the barrier glass plate, allowing the mixed liquid of the sand grains and the liquid nitrogen in the dispersing bin to penetrate through the dispersing plate to contact air, and gasifying and volatilizing the liquid nitrogen to obtain the sand grains, so that the sand grains are dispersed. The device and the method are high in automation degree; and by the device and the method, the sand grains can be quickly dispersed, the characteristics of the sand grains cannot be damaged, and the measurement accuracy of the sand grains is guaranteed.

Description

technical field [0001] The invention relates to a silt particle dispersing device and a method thereof, which are mainly used in the field of silt particle analysis and are a necessary step for studying the characteristics of the silt particle. Background technique [0002] When performing image or microscope analysis of sediment particles, the sediment particles must be fully dispersed in order to obtain parameters such as the size and shape of individual sediment particles. It is difficult to satisfy the sufficient dispersion of sediment particles, and the phenomenon of mutual overlapping of sediment particles often occurs. From the image, it can only be judged as a single particle, which affects the analysis of sediment particles and causes measurement errors. Therefore, it is urgent to establish an automatic dispersing device for silt particles to realize rapid dispersal of silt particles, improve measurement automation, and ensure the accuracy of silt analysis.
