Light-weight and high-strength porcelain particle manufactured by utilizing sludge from sugar house and manufacturing method thereof

Abstract

The invention belongs to the technical field of the recovery and the resource utilization of sludge, and particularly relates to a light-weight and high-strength porcelain particle manufactured by utilizing the sludge from a sugar house and a manufacturing method thereof. The manufacturing method comprises the following steps: first, crushing 30-50 parts of construction rubbish to obtain a construction rubbish crushed material; and uniformly mixing the construction rubbish crushed material with 30-40 parts of the sludge from the sugar house and 20-40 parts of potash feldspar powder, and then,roasting the mixture at 1150-1500 DEG C for 20-120 minutes, and cooling the mixture to obtain the light-weight and high-strength porcelain particle. In the invention, the sludge from the sugar house,the construction rubbish and the potash feldspar powder are mixed according to a certain proportion; the synergistic effects among the sludge from the sugar house, the construction rubbish and the potash feldspar powder are exerted, so that the strength of the manufactured light-weight and high-strength porcelain particle is up to 60-120 MPa; and the light-weight and high-strength porcelain particle has the physical performances and the mechanical performances more excellent than those of a general natural stone. By using the light-weight and high-strength porcelain particle, not only can waste be changed into valuables articles, but also the environmental pollution is improved favorably; the principles of harmlessness, reduction and resource utilization for the treatment of solid waste in China are met; and the light-weight and high-strength porcelain particle has obvious economic benefit and social benefit.

Description

Technical field [0001] The invention belongs to the technical field of resource recycling and utilization, and in particular relates to a light-weight high-strength porcelain granule manufactured from sugar factory sludge and a manufacturing method thereof. Background technique [0002] Sugar mill sludge is a waste produced by the sugar industry during the production of cane sugar. It contains a variety of organic substances, which pollute the environment due to its high moisture content and corruption. There are nearly one million tons every year. Since there is no comprehensive utilization, the landfill method is used for disposal, which causes waste of resources and secondary pollution. So far, there is no proper way to deal with it. [0003] At the same time, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. According to the standard of 500-600 tons / 10,000 square meters, by 2020, my country will increase construction ...

Problems solved by technology

However, this manufacturing method needs to dehydrate the sewage first, and the production efficiency is low, resulting in a waste of resources and increasing the cost. Moreover, because the technical solution only uses sludge as a component and does not contain chemical components that can improve product strength, it can only be used The ceramsite with low strength and poor mechanical properties can be obtained, and the ceramic particles with light weight, high strength and good mechanical properties cannot be obtained.
