Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a water conservancy engineering silt removal device and a removal method thereof. Background Art

[0002] In the field of water conservancy projects, sediment removal operations are of vital importance to ensure that rivers are unobstructed and water conservancy facilities operate efficiently. With the continuous development of water conservancy projects and the enhancement of environmental protection awareness, the requirements for sediment removal technology are also increasing. At present, there are some sediment removal devices on the market. Most of these devices are based on the traditional physical sedimentation principle and have the following defects: limited sedimentation efficiency; especially for water bodies containing a large number of fine particles and floating objects, traditional sedimentation tanks are often difficult to achieve ideal sedimentation effects; Filter devices are easy to clog. Due to the wide variety of impurities in the water body, the filter or screen is very easy to be clogged during use, resulting in poor water flow and the need for frequent cleaning and maintenance. In addition, the existing technical solutions also have shortcomings in the addition of precipitants. Most devices lack a mechanism for flexibly adjusting the amount of precipitant added, and can only be added according to the preset dosage, resulting in low purification efficiency and serious waste of resources when treating water bodies with different turbidity.

At the same time, the precipitant in the reagent box 5 is mixed with muddy water through the mixing valve 15, which accelerates the transformation of mud into flocculent sediment, and finally the treated water is discharged from the water outlet pipe 18.

[0040] The specific mixing valve 15 includes a first cylinder 151, a second cylinder 152 and a third cylinder 153. The second cylinder 152 and the third cylinder 153 are fixed on the top of the first cylinder 151 and the third cylinder 153 is located on one side of the second cylinder 152.
