River and lake desilting bottom mud brick and preparation method thereof
The invention relates to a river and lake desilting bottom mud brick and a preparation method thereof, the preparation method comprises the following steps: desilting bottom mud, adding a flocculating agent for sedimentation after the completion of dredging, then conveying to a mechanical device for dehydration, and then standing, stacking and naturally airing. After dehydrated cement cakes enter a crusher to be crushed, a bottom mud matrix is screened out through a screen and conveyed to a mixing bin, a water reducing agent is added firstly and mixed evenly, and then the mixture is stirred and mixed evenly with industrial waste residues, a calcium additive, construction waste, an exciting agent and other materials. And conveying the mixed material to a digestion bin for aging. And carrying out compression molding on the aged materials under pressure through a brick making machine. The brick blank is subjected to a low-temperature hydrothermal reaction to prepare the finished bottom mud brick. River and lake bottom mud in different regions including bottom mud stacked in a storage yard can be treated and utilized, sintering and long-time maintenance are avoided, and good social environment and economic benefits can be generated.
本发明涉及一种河湖清淤底泥砖及其制备方法，清淤底泥，疏浚完成后加入絮凝剂进行沉降，然后输送到机械装置进行脱水，再静置、堆放自然晾晒。脱水泥饼进入破碎机破碎后，通过筛网筛出底泥基质，传送到混合料仓，先添加减水剂混合均匀，再与工业废渣、钙质添加剂、建筑废弃物、激发剂等物料进行搅拌混匀。混合物料传送至消解仓进行陈化。将陈化后的通过制砖机在压力下压制成型。砖坯通过低温水热反应制备得到成品底泥砖。可以对不同地域的河湖底泥包括堆场堆置底泥进行处理利用，避免烧结和长时间养护，可产生良好的社会环境和经济效益。
