A suction filter type water and sand separation device for annular water tank

Abstract

The invention discloses a suction filter type water-sand separation device for an annular water tank, which comprises a water-sand sample separation device and a suction filter device. The seal is connected with isolation chambers and filter chambers arranged alternately. The filter element is arranged on the bottom plate of the filter chamber. The bottom plates of the mixed liquid collection chamber, the isolation chamber and the filter chamber are all provided with circular through water holes. The bottom plate of the isolation chamber is set There is a motorized sealing device, and the suction and filtration device includes a clear liquid collection chamber, which is sealed and connected with the bottom isolation chamber. There is an air extraction hole on the side of the clear liquid collection chamber, and a water outlet valve is installed at the bottom of the clear liquid collection chamber. The air extraction hole passes through The catheter is connected to an air pump. The invention provides a suction filter type water-sand separation device for an annular water tank, which can quickly separate the water-sand mixture sample flowing out of the annular water tank under working conditions, reduce the contact time between sediment and water body, and improve the experimental efficiency. Result accuracy.

Description

technical field [0001] The invention relates to a suction filter type water-sand separation device for an annular water tank, belonging to the technical field of water-sand separation. Background technique [0002] In many experiments on water-sediment interaction, it is necessary to have accurate grasp of water samples and sediment samples at the same time. The annular flume is a common experimental instrument used in experiments involving water and sand movement processes. It successfully simulates an infinitely long straight flume, which improves the feasibility of observation of sediment movement processes such as start-up, suspension, and settlement from a technical point of view. In the experimental research on the adsorption of pollutants by sediments under dynamic conditions by using annular tanks, the mathematical description of the sediment movement process requires the analysis of the physical parameters of the sediment samples, so it is necessary to carry out che...

AI Technical Summary

Problems solved by technology

The samples taken directly from the water tank are all water-sand mixed samples, which must be further processed to meet the standards of chemical analysis experiments, such as centrifugation in a centrifuge and filtration, etc. These treatments often consume a long time and reduce the efficiency of the experiment. During the process, the sediment and the water body are kept in constant contact, and the adsorption reaction is still going on, which greatly reduces the accuracy of the experimental results.

[0004] Based on the above, it can be seen that in the current water and sand experiments using annular tanks, sampling is difficult and it is difficult to separate water samples and sand samples in time, resulting in low experimental efficiency and the inability to guarantee the accuracy of experimental results
