Ultrasonic-based centrifugal type bidirectional automatic-backwashing water-sediment separating device

Abstract

The invention discloses an ultrasonic-based centrifugal type bidirectional automatic-backwashing water-sediment separating device. The water-sediment separating device is characterized by comprising a pipeline unit (1), a vibration generating unit (2), a water flow monitoring unit (3) and an automatic control unit (4), wherein the pipeline unit (1) is arranged inside the vibration generating unit (2); the water flow monitoring unit (3) is arranged inside the pipeline unit (1); the automatic control unit (4) is connected with the vibration generating unit (2) and the flow monitoring unit (3). The ultrasonic-based centrifugal type bidirectional automatic-backwashing water-sediment separating device provided by the invention can depend on centrifugal layering of self-hydraulic power and a filter screen to conduct water-sediment separation, is high in filter precision, can keep internal cleaning of the filter screen through the centrifugal backwashing mechanism, and achieves the long-time high-efficiency filtered water quality.

Description

technical field [0001] The invention relates to a water and sand separation device based on ultrasonic centrifugal two-way automatic backwashing, in particular to a water-sand separation device that effectively utilizes the principle of centrifugal layering and ultrasonic two-way backwashing to clean the solid-liquid two-phase water containing sediment during the process of transporting water. A device for separating streams belongs to the technical field of hydraulic engineering. Background technique [0002] The water supply project from the Yellow River in the lower reaches of the Yellow River began in the early 1950s. It has developed from the initial use of agricultural water to an all-round water supply for industrial and agricultural production and urban and rural residents. Taking Shandong in the lower reaches of the Yellow River as an example, there are 72 Yellow River diversion irrigation areas of more than 10,000 mu in the Shandong section of the lower Yellow Rive...

AI Technical Summary

Problems solved by technology

These fine-grained sediments are very difficult to deal with. Currently, under dynamic conditions, there are many projects that rely on hydraulic energy to treat sediments, but they are powerless to deal with sediments smaller than 0.05mm. This has brought great harm to industrial water and people's domestic water. In terms of agricultural water use, the promotion and application of advanced water-saving technologies such as agricultural sprinkler irrigation are seriously restricted due to the large amount of fine-grained sediment in the river water.
