Abstract
本发明公开一种水工混凝土人工砂洗砂装置及方法，属于人工砂洗砂技术领域，包括：立式洗砂组件、卧式洗砂组件、静置沉降装置和控制器；立式洗砂组件设有洗涤液进口和第一溢流口，洗涤液进口用于通入洗涤液，第一溢流口用于排出立式洗砂后上层的泥粉水；卧式洗砂组件设有第二溢流口，用于排出卧式洗砂后上层的泥粉水；静置沉降装置设有第三溢流口，用于排出静置沉降后上层的泥粉水；控制器分别与立式洗砂组件、卧式洗砂组件和静置沉降装置电连接，用于控制依次完成立式初洗排出泥粉水、卧式精洗排出泥粉水和静置沉降排出泥粉水。本发明通过三级洗砂工艺，配合三次分层溢流排出泥粉水，最大限度保留了对混凝土性能有益的石粉，提升了人工砂品质。
