Description

Technical Field

[0001] The present invention relates to the technical field of separation devices, and more particularly to a mud-water separation device. Background Art

[0002] Pipe jacking construction is a trenchless construction method, which is a pipeline laying construction technology with little or no excavation. Pipe jacking construction is to generate jacking force in the working pit, overcome the friction between the pipeline and the surrounding soil, jack the pipeline into the soil according to the designed slope, and transport the soil away. After one pipe is jacked into the soil layer, the second pipe is lowered and jacked forward continuously. Its principle is to use the thrust of the main jacking cylinders, between the pipelines and the relay chambers, etc., to push the tool pipe or tunneling machine from the working pit through the soil layer and into the receiving pit for hoisting. The pipeline follows the tool pipe or tunneling machine and is buried between the two pits. When excavating soil during pipe jacking construction, the soil contains moisture, which is not convenient for transportation and has a high cost. Summary of the Invention

The clamping plate 13 is regularly opened to remove the bottom plate of the extrusion box 5, and the soil is collected; the water in the collection tank 6 enters the mixing box 7 through the first water pipe 15. A flocculant is added to the mixing box 7, and the flocculant causes the soil contained in the water to be further flocculated. The mixture in the mixing box 7 enters the separation box 18 through the second water pipe 16. The filter screen 17 in the separation box 18 filters, and the flocculant stays on the filter screen 17. Moreover, the fixed rod 10 at the top of the separation box 18 stirs the mixture while reciprocating under the reciprocating motor 8, which is beneficial for the water to pass through the filter screen 17.
