Mud recycling and separating system and using method thereof

Abstract

The invention relates to a mud recycling and separating system. The system comprises a stone separation device and a sand-water separation device, the sand-water separation device is positioned belowthe stone separation device; the lower part of the stone separation device is communicated with a communicating pipe; the sand-water separation device comprises a material bearing hopper located belowthe communicating pipe, a circular pipeline which communicates with the outlet end of the material bearing hopper and is obliquely arranged, and a second support used for supporting the circular pipeline. Spiral blades are arranged in the circular pipeline, a water output port is formed in the lower end of the circular pipeline, and a driving motor for driving the spiral blades to rotate is arranged at one end of the circular pipeline. The mud recycling and separating system has the effects that stones, sand and water are separated, the separation degree of the stones, the sand and the wateris enhanced, and the water is recycled.

Description

technical field [0001] The invention relates to the technical field of mud recycling, in particular to a sand-stone separator for mud recycling. Background technique [0002] The commercial concrete mixing station inevitably produces a large amount of wastewater during the cleaning process of the commercial concrete transport vehicle. This wastewater not only contains conventional building materials such as sand and cement, but also contains various types of concrete additives. If it is discharged directly, it will not only cause a waste of building material resources, but also cause serious pollution to the natural environment. Most of the current concrete mixing and viscous clear wastewater adopts multi-stage slag separation and natural precipitation method for solid-liquid separation. Not only is the treatment efficiency low, but also the settled wastewater cannot be recycled due to the high content of suspended solids. The resource recovery system of a commercial concre...

Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: although it is provided with a pre-screening device, a buffer device and a re-screening device to screen the sand, the sand generally contains water, which does not separate the water. It is easy to cause the sand to be combined with water after the separation of the stones, and it will be compacted after solidification, which will affect the reuse of the sand
