The invention discloses a sorting device of ultra-fine sediment and a use method of the sorting device of the ultra-fine sediment. The sorting device of the ultra-fine sediment comprises a sorting groove, a transmission device, suspended sediment samplers and a bottom sediment collector. The sorting groove comprises a sorting groove upper disk and a sorting groove lower disk which are used for achieving suspension and sedimentation of the sediment. The transmission device is connected with the sorting groove and used for achieving ascending and descending of the sorting groove upper disk, turning of the sorting groove upper disk and the sorting groove lower disk and adjustment of the rotation speed. The suspended sediment samplers are arranged on the outer side wall of the sorting groove lower disk and used for collecting suspended sediment. The bottom of the bottom sediment collector is attached to the bottom of the sorting groove lower disk. The side portion of the bottom sediment collector is attached to the outer side wall of the sorting groove lower disk. The upper portion of the bottom sediment collector is detachably installed on the outer side wall of the sorting groove lower disk. The sorting device has the advantages of being easy to operate, high in applicability, high in sorting efficiency, good in effect and the like, and the sorting device is particularly suitablefor sorting out the ultra-fine sediment of a specific grain size or grade from natural sediment of wide grain size grades.
Description
technical field [0001] The invention relates to the technical field of sediment sorting devices, in particular to a sorting device for ultrafine grained sand and a method for using the same. Background technique [0002] Under laboratory and field conditions, the current separation of sediment is mainly through two methods: physical separation and wet separation. [0003] In the laboratory, it is mainly through physical sorting, that is, screen sorting. The screen sorting method requires pretreatment of the sediment such as drying and grinding, and the size of the sediment that can be sorted is limited by the pore size of the screen. It takes longer to sieve sediment with a finer particle size, and it is difficult to further sieve ultrafine sediment with a particle size of less than 63 μm by screen sorting. [0004] Under field conditions, in order to improve the economic benefits of river sediment, the wet method is usually used to separate the sediment by using the diffe...
