Sintering method brick making process of building waste mud

Abstract

The embodiment of the invention discloses a sintering method brick making process of building waste mud, and the method comprises the following steps: coarsely filtering the collected building mud, and discharging the filtered building mud into a sedimentation tank; after the waste mud is precipitated, removing supernatant liquid and floating objects; carrying out sand separation and sand washingtreatment on the residual slurry, and discharging the residual slurry into a flocculation basin; adding a flocculating agent, quickly stirring, standing, and removing supernatant liquid; dehydrating the flocculated slurry to obtain a dehydrated mud cake with the water content of less than or equal to 35%; then adding water into 60%-70% of the dehydrated mud cake, 15%-25% of coal gangue and 10%-20%of stone shale, and stirring; feeding uniformly stirred ingredients into an aging tank for aging; crushing and weighing the ingredients, and then sending the ingredients to a brick making machine formaking a blank; and baking the obtained brick blank in a baking kiln to obtain the finished product brick. According to the building waste mud brick making process, the treatment cost of the waste mud can be reduced, the problem of environmental pollution caused by the waste mud is solved, and the economic value is reproduced by recycling the waste mud.

Description

technical field [0001] The embodiment of the present invention relates to the field of brick making, in particular to a brick making process of construction waste mud by pressing method. Background technique [0002] The traditional construction industry uses a large number of clay bricks as wall materials, and the production of a large number of clay bricks will definitely destroy farmland, consume farmland land resources, and seriously damage the ecological balance. In 2010, the use of clay bricks was prohibited in all cities across the country, so a raw material must be found to replace traditional clay raw materials for making bricks. [0003] With the continuous development of the construction industry, a large amount of waste mud, including sand, bentonite and a large amount of water, will be produced during the construction process. The current treatment method is to use tank trucks to load the waste mud on site. There are many problems: the amount of waste mud produ...

Problems solved by technology

[0003] With the continuous development of the construction industry, a large amount of waste mud, including sand, bentonite and a large amount of water, will be produced during the construction process. The current treatment method is to use tank trucks to load the waste mud on site. There are many problems: the amount of waste mud produced by construction is huge, the cost of loading and transportation is high, and the efficiency is low; the mud will pollute the environment due to mud leakage during transportation; the mud is discarded and buried at random, causing greater pollution

[0004] The inventor of the present application found that, in the prior art, the construction waste mud is subjected to mud-water separation treatment at the construction site, so that the water content is lower than 60%, the main treatment method is still landfill, and the treatment cost is high, accounting for the land area of ​​the construction site. Large, low efficiency, seriously affecting the construction progress
