Embodiment 2

[0052] Such as Figure 1~6 As shown, a centrifugal two-way backwash automatic irrigation device for diverting the Yellow River is characterized in that:

[0053] The filter screen is a five-layer metal filter screen with different apertures, and its working principle is as follows:

[0054] 20 mesh is used as the fifth layer filter, which can filter out gravel, dead branches and garbage with large particle size;

[0055] 60 mesh is selected as the fourth layer of filter, which can filter out coarse sand particles, etc.;

[0056] 150 mesh is selected as the third layer of filter, which can filter out most of the medium sand particles;

[0057] 180 mesh is used as the second filter, which can filter out most of the fine sand particles;

[0058] 250 mesh is selected as the first layer of filter, which can filter out most of the sediment particles and flocculent impurities.

[0059] The annular pipe 11 is placed at 60° to the horizontal plane, the large ring radius of the annu...

Abstract

The invention discloses a centrifugal type bidirectional backwashing automatic Yellow River irrigation device. The centrifugal type bidirectional backwashing automatic Yellow River irrigation device is characterized by comprising a pipeline unit (1), a light beam generation inductor unit (2) and an automatic control unit (3), wherein the pipeline unit (1) is arranged in the light beam generation inductor unit (2); and the automatic control unit (3) is electrically connected with the light beam generation inductor unit (2). The centrifugal type bidirectional backwashing automatic Yellow River irrigation device disclosed by the invention has high filtering precision; the inner part keeps clean by a centrifugal backwashing mechanism; water can be filtered efficiently for a long time and automatic control of water purification and washing is realized by virtue of a light induction technology; a problem of blocking of an existing irrigation device is solved radically; and the centrifugal type bidirectional backwashing automatic Yellow River irrigation device can be automatically washed, is convenient to operate and has a low price, and can be applied to the market in a large scale, so that the development of national farmland water-saving irrigation projects is effectively propelled.

Description

technical field [0001] The invention relates to a centrifugal type two-way backwash automatic irrigation device for diverting the Yellow River, in particular to a device that effectively utilizes centrifugal stratification and light-sensing principles to separate water and sand from Yellow River water containing sediment in the process of transporting water, and belongs to Water conservancy engineering technology field. Background technique [0002] The water supply project of diversion from the Yellow River in the lower reaches of the Yellow River began in the early 1950s. The water supply from the Yellow River has gone through complex and tortuous processes such as exploration and experimentation, large-scale diversion and storage, irrigation suspension, restoration and rectification, stable development, and unified dispatching and management. Agricultural water has developed into an all-round water supply for industrial and agricultural production and urban and rural resi...
