Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge equipment, in particular to a reclaimed water supply system for centrifuge equipment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Centrifuges are needed in the sewage treatment process to separate solid particles from liquids in suspensions.

[0003] At present, the centrifuge dosing machine, dilution panel and plunger pump coolant all use tap water. In order to reduce costs and save energy, some centrifuge rooms have switched to using recycled water for all equipment except domestic water. However, the water pressure of recycled water is often unstable, which leads to insufficient water pressure at the dilution panel, resulting in the flocculant dilution concentration in the dilution panel unable to accurately meet the sewage treatment requirements, thus affecting the sewage treatment effect.

When the water pressure of the grey water in the grey water supply pipe 2 is insufficient, the pressurized grey water stored in the pressurization storage unit 6 can be released into the grey water supply pipe 2 to increase the outlet water pressure. In addition, by arranging a pressure stabilizing unit 5 in front of the dilution unit 4, the outlet water pressure of the grey water supply pipe 2 is maintained stable by the pressure stabilizing unit 5, which can make the grey water entering the dilution unit 4 always maintain a stable water pressure, so as to accurately meet the dilution requirement of the centrifuge flocculant concentration.
