Mud-sand-water filtering device for laboratories and vibration anti-blocking method

Abstract

The invention discloses a mud-sand-water filtering device for laboratories. The mud-sand-water filtering device comprises a conical water inlet hopper with a large upper part and a small lower part, and the conical water inlet hopper is downwards connected with a water inlet pipe; the water inlet pipe is downwards communicated with a water inlet cavity, the side wall of the water inlet cavity is connected with a filter plate; the filter plate is connected with a water outlet cavity; a plurality of filter holes communicating with the water inlet cavity and the water outlet cavity are distributed in the filter plate; the water outlet cavity is connected with a water outlet pipe; a plurality of vibration cavities are uniformly formed in the filter plate, and an elastic ball is arranged in each vibration cavity. During work, the elastic balls continuously jumps in the vibration cavities and impact the inner walls of the vibration cavities, so that vibration impact is generated on the filter plate, impurities in the filter holes are more easily separated from the filter holes, and a good anti-blocking effect is achieved. Due to the precipitation process and the filtering process, the effects of purifying water and recycling mud and sand are good, the burden of a drainage system is reduced, and mud and sand waste is reduced.

Description

technical field [0001] The invention relates to the technical field of river engineering model test. Background technique [0002] In the field of hydraulic engineering technology, various hydraulic model experiments are often required. For example, the river engineering model test is to reduce the river channel shape and the characteristics of water flow and sediment movement into a model according to similar criteria to simulate the river sediment movement and the scouring and sedimentation deformation of the river bed. In the experiment, water containing mud and sand will be continuously produced, and the mud and sand are often purchased experimental materials. If the water containing mud and sand is directly discharged, the experimental materials will be wasted on the one hand, and the load of the drainage system will be increased on the other hand, which will easily cause drainage blockage in severe cases. SUMMARY OF THE INVENTION [0003] The purpose of the present ...
