Description

Technical Field

[0001] The present application relates to the technical field of metering bins, and in particular to a mother powder metering bin suitable for a small fly ash stabilization system. Background Art

[0002] The basic principle of fly ash solidification equipment cement solidification technology is to contain and reduce harmful solidified wastes through physical and chemical effects under certain conditions, so that they will eventually become hydroxides or complexes, reduce their permeability and mobility, and thus achieve the purpose of stabilization or harmlessness. The method of using cement to solidify fly ash is mainly through the hydration of cement, which absorbs and settles some metal ions in the fly ash in physical and chemical ways, so that the heavy metal elements in the fly ash will eventually exist stably in the cement in the form of certain compounds, thereby preventing the invasive toxicity characteristics of the heavy metal elements from causing harm to the environment.

[0003] In the fly ash stabilization system in the related technology, in order to meet the requirements of environmental assessment and process production, the system usually has an independent fly ash metering bin and a cement metering bin to meet the weighing of fly ash and cement. However, for some fly ash stabilization systems with small processing capacity, saving floor space and reducing cost investment have become particularly important. The use of two independent powder metering bins has a large floor space and requires two independent weighing sensors and arch breakers, which is costly.

[0004] Therefore, we propose a mother powder metering silo suitable for small fly ash stabilization systems to solve the above problems. Utility Model Content
