TECHNICAL FIELD

[0002] In water conservancy construction, the silt separating machine is the key part of the silt separating device, and is mainly used for effectively separating the silt in the sand-containing water body from the water.
[0003] In the mud separator, a filter screen is usually provided to filter impurities in the mud. The filter screen is often provided with fixed-size mesh holes. Once the impurity particles are stuck in the mesh holes of the filter screen, the effective filtering area of the filter screen will decrease, which makes the mud flow through the filter screen slow, and the amount of mud that can be processed in a unit of time also decreases accordingly. As a result, the efficiency of the silt separation is greatly reduced, which adversely affects the construction progress.
[0004] In addition, the mud produced in water conservancy construction has complex and diverse properties. For example, in the scenarios of river dredging, reservoir construction, pile foundation construction, etc., the mud differs in particle size, concentration, and viscosity. However, the filter screen with a fixed mesh size is only applicable to a certain range of mud particles. When encountering mud with large fluctuations in particle size, it is difficult to optimize the separation effect because the mesh size cannot be adjusted. For example, for fine-grained mud, if the fixed mesh size is too large, the silt cannot be completely separated. For coarse-grained mud, if the mesh size is too small, it is easy to cause blockage, resulting in reduced separation efficiency. SUMMARY
