Spiral-flow type desilting device for water conservancy project construction and implementation method thereof

Abstract

The invention discloses a spiral-flow type desilting device for water conservancy project construction and an implementation method thereof. The spiral-flow type desilting device for water conservancy project construction comprises a box body, a conical part installed at the lower end of the box body and a desilting bin installed at the lower end of the conical part. A motor A is started to work, wherein the output end of the motor A is connected with a spiral rod A, so that the spiral rod A is driven to rotate; the bevel gear is driven to rotate through meshing connection of a gear piece and the bevel gear, and since the other end of the bevel gear is connected with a spiral rod B, the spiral rod B can rotate; the spiral rod B is installed in the channel, sand deposited at the upper end of the negative pressure cover can be conveyed into the sand collecting box through the channel, and the sand is accumulated in the sand collecting box; due to the fact that the channel is obliquely installed, water in the channel is difficult to enter the channel; and the spiral rod A is arranged in the channel and is transported to the outer end through the spiral rod A, so that sand can be prevented from being raised at the desilting bin, the sand is prevented from being muddy again, and the sand is convenient to take out.

Description

technical field [0001] The invention relates to the technical field of water conservancy project construction, in particular to a swirl type sand settling device for water conservancy project construction and an implementation method thereof. Background technique [0002] Water conservancy engineering construction is a kind of engineering construction. Water conservancy engineering construction has many similarities with general civil engineering such as road, railway, bridge and housing construction. For example: the main construction objects are mostly earthwork, stonework, concrete, metal structure and electromechanical equipment installation; some construction methods are the same; some construction machinery can be used in common; some construction organization and management can also be used for reference. [0003] In the construction process of water conservancy projects, a grit chamber is usually built to facilitate the separation of water and sand. When the existing...

AI Technical Summary

Problems solved by technology

[0003] In the construction process of water conservancy projects, a grit chamber is usually built to facilitate the separation of water and sand. When the existing grit chamber is in use, it is troublesome to take out the sand, and it is easy to muddy the internal water, resulting in relatively heavy sand. Difficult to take out, the separation effect is poor, and when taken out, it is easy to be mixed with water, and the use effect is not good
