Description

technical field [0001] The invention relates to a screening machine, in particular to a sediment particle size wet screening machine. Background technique [0002] The different particle sizes of marine sediments can indicate the hydrodynamic changes in the depositional environment, so in oceanographic research, the particle size analysis of sediments is very important. The traditional sediment particle size analysis is to use a grading sieve with an aperture of 0.063mm to remove the fine particles, then collect the upper particles and dry them, and then use mesh sieves of different particle sizes to sieve. Detritus particles will bounce on the sieve, especially fine particles will float up, and the grading sieve is not stacked tightly, which will cause the loss of samples, and at the same time, a large number of mineral particles will be stuck on the mesh of the sieve. The brush brushes these particles from the mesh forcefully, and a certain amount of sample loss will be c...
