Waste building mud sand washing treatment system

Abstract

The invention relates to a waste building mud sand washing treatment system. The system comprises a washing machine; the washing machine comprises a sand washing tank, water wheels and a first spraying frame; the sand washing tank is at least provided with two water washing tanks connected end to end; the water wheels are arranged in the two water washing tanks respectively, the axis directions of the water wheels are perpendicular to the arrangement direction of the water washing tanks, wheel shafts of the water wheels are rotationally connected to the sand washing tank and can rotate in the same direction, and a plurality of sand bailing tanks with leaking holes are evenly formed in the circumferential surfaces of the water wheels; and the first spraying frame is arranged above the sides, close to each other, of the two water washing tanks, and spraying heads of the first spraying frame can spray water to the sides, close to each other, of the two water wheels at the same time. With the waste building mud sand washing treatment system adopted, the sand washing efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of construction waste recycling, in particular to a water washing treatment system for waste building mud and sand. Background technique [0002] At present, in the construction waste recycling process, when the construction waste is crushed and the sand is recovered from the construction waste, it is generally necessary to wash the sand to wash off the sludge adhered to the sand surface to obtain a clean washing process. For sand or machine-made sand, in the process of sand washing, sand washing equipment is needed to select and wash sand and gravel, remove impurities covering the surface of sand and gravel, and destroy the water vapor layer covering sand grains at the same time, so as to facilitate dehydration and play a role in dehydration. To the effect of efficient sand washing and cleaning. [0003] At present, sand washing equipment generally includes a washing tank and an impeller. There a...

Problems solved by technology

[0004] However, during the rotation of the impeller of this type of water washing equipment, although the sediment can be fished out from the sand removal tank, when the sand removal tank rotates to the discharge side with the impeller, due to the strong adhesion of the sediment, it is difficult to completely remove the sand from the sand removal tank. If the sand is discharged from the sand tank, a large amount of sand will adhere to the sand fishing tank, which greatly reduces the sand washing efficiency.
