Abstract
The invention discloses a method for using a water-saving and energy-saving sandstone aggregate water washing system, and relates to the field of sandstone aggregate, in particular to a water-saving and energy-saving sandstone aggregate water washing system and a use method. The purpose of the present invention is to solve the problem of flocculant accumulation in the sand aggregate water washing system. A water-saving and energy-saving sand and gravel aggregate water washing system, which includes a crusher, an inspection screen, a large-caliber anti-blocking nozzle, a mixed aggregate belt conveyor, a fan-shaped nozzle, a finished product screen, a finished aggregate belt conveyor, a light waste water tank, and a light waste water Slurry pump, sand washing machine, dewatering screen, finished sand belt conveyor, concentrated wastewater slurry pump, concentrated wastewater tank, plate and frame filter press, filter cake belt conveyor, clean water tank and clean water pump; use methods: 1. Crushing; Two, the first screening; three, the second screening; four, wheel washing; five, wastewater treatment. Beneficial effects: 1. No flocculant is added; 2. The effluent quality is generally below 5mg / L; 3. The water consumption is reduced to half. The invention is mainly used for water washing of sandstone aggregates.
Description
technical field [0001] The invention relates to the field of sand and gravel aggregates, in particular to a water-saving and energy-saving sand and gravel aggregate washing system and a use method. Background technique [0002] At present, the wet washing process commonly used in the sand and gravel aggregate industry is water washing-dosing precipitation-press filtration-reuse. This method consumes a lot of water, requires a lot of investment, and the quality of the sedimentation effluent is unstable. The quality of the effluent water is generally between 10mg / L and 20mg / L (SS content), large dosage and other characteristics. In addition, during the recycling process of recycled water, the flocculant has been accumulating, which will have a certain impact on the quality of the aggregate. [0003] The effluent water quality of the sedimentation tank is unstable and the water consumption is large. At the same time, the investment cost of the sedimentation tank is high. Due ...
