Description

Technical Field

[0001] The utility model relates to the technical field of dewatering machines, in particular to a process-reconstructed sand washing slurry dewatering machine. Background Art

[0002] Sand washing wastewater refers to the wastewater generated by water-washed sand and gravel production enterprises during the sand washing process. Sand and gravel are one of the basic materials for construction. With the increasing demand for sand and gravel in China, natural sand is facing the pressure of resource reduction and environmental protection. Water-washed sand will become an important source of construction sand and enter the building materials market. Therefore, the prior art discloses a variety of sand washing mud dewatering machines, such as a mud dewatering belt filter press proposed in the Chinese utility model patent with publication number CN214781436U. The filter press pours concentrated mud into a distributor, and after being stirred by the distributor, the concentrated mud is evenly distributed on the surface of the filter belt. The concentrated mud separates free water and mud through the filter belt, and the free water falls into the water tank through the filter belt. The mud separated from the free water enters the filter belt squeezing and dewatering mechanism. The filter belt squeezing and dewatering mechanism forms a mud cake through squeezing and dehydration of the squeezing roller, the squeezing roller, the dewatering roller and the rotating roller, and is discharged from the two driving rubber rollers. This device integrates concentrated filter pressing and single-cloth water filtration, making the dewatering operation more efficient.

[0003] However, the above-mentioned prior art uses a pressing mechanism composed of multiple pressing rollers, multiple squeezing rollers and a pressing belt to dewater the mud. The pressing belt is guided through multiple twists and turns and requires multiple drive motors to drive it, resulting in a relatively complex structure and a large volume, which is not conducive to installation in small sites.
