Description

Technical field:

[0001] The utility model relates to the technical field of irrigation equipment, in particular to a direct-filtered water reuse device based on Yellow River water irrigation equipment. Background technology:

[0002] The Inner Mongolia section of the Yellow River is 843.5 kilometers long, accounting for about one-sixth of the total length of the Yellow River. The Yellow River diversion irrigation in the Hetao region began in the Qin and Han Dynasties, with a history of more than 2,000 years. With the nourishment of the Yellow River water, the Hetao region, with an average annual precipitation of less than 200 mm and an average annual evaporation of more than 2,000 mm, has become a large agricultural area. In recent years, the direct filtration irrigation equipment for diverting the Yellow River has become the mainstream equipment for irrigation with Yellow River water, but most of the irrigation equipment is relatively simple, not mature, and has a high failure rate. For example, the pumping power of the direct filtration irrigation equipment for diverting the Yellow River comes from a centrifugal pump, which is well known. It is known that a centrifugal pump must be filled with water before it can work. The purpose is to discharge the air in the pump casing. When the impeller throws the water out, a low-pressure area is formed in the pump casing, and the water outside the pump is pressed into the pump under the action of atmospheric pressure. If the centrifugal pump is not filled with water, it will not work. Therefore, manual water filling is required before starting the equipment each time, which is time-consuming and labor-intensive, and has low work efficiency. At the same time, the power of the centrifugal pump comes from the diesel engine, and the diesel engine cooling water tank also needs to be regularly replenished with cooling water. For this reason, the utility model provides a direct filtration water reuse device based on the Yellow River water irrigation equipment. Utility model content:
