Problems solved by technology

[0003] At present, there are many types of regenerated bricks made from construction waste. During the production and crushing process of the existing construction waste regenerated bricks, due to the large amount of various materials in the construction waste, it is impossible to crush the hard construction waste. In the molding process, one-time extrusion molding is not used, which is prone to the phenomenon that the surface of recycled resource bricks is tight and the interior is loose

Embodiment Construction

[0040] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0041] Combine below Figure 1-9 Describe the specific implementation of the present invention, a method for preparing recycled resource bricks based on construction waste, the method includes the following steps;

[0042] Step 1: Collect construction waste, remove the impurities in the construction waste for later use;

[0043] Step 2: crush the collected construction waste and screen out granular materials;

[0044] Step 3: Add water and additives to the crushed granular material for component mixing to form recycled resource brick mud;

[0045] Step 4: The recycled resource brick mud is pressed twice to form a sintered brick body;

[0046] Step 5: Put the sintered brick body into the brick kiln for roasting, drying and shaping, and make a new type of sintered brick after leaving the kiln;

[0047] In the step 2, the step 3 and the step 4,...

Abstract

The invention discloses a method for preparing recycled resource bricks based on construction wastes. The method comprises the following steps: step one, collecting construction wastes and removing impurities in the construction wastes for later use; step two, crushing the collected construction wastes and screening granular materials; step three, adding water and additives into the crushed granular materials and fully stirring to form a recycled resource brick pug; step four, pressing the recycled resource brick pug twice to form sintered brick blanks; and step five, putting the sintered brick blanks into a brick kiln, then roasting, drying and shaping, and taking the sintered brick blanks out of the kiln to obtain novel sintered bricks. Processing of the step two, the step three and the step four is completed in an integrated crushing and forming device; and the construction wastes are crushed in a manner of combining extrusion and knocking, so that the construction wastes with hard textures are crushed, and the crushing capacity of the device is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for preparing recycled resource bricks based on construction waste. Background technique [0002] Construction waste is the waste produced after the demolition of urban buildings. It is mainly composed of waste concrete, waste mortar, waste masonry, waste wood, etc. Most of the construction waste is transported to the suburbs or surrounding cities for simple landfill or landfill without any treatment. Open storage not only wastes land and resources, but also pollutes the environment. At present, the amount of construction waste in my country accounts for 30-40% of the total annual urban waste. Construction waste has become one of the main solid wastes in cities. How to properly deal with these construction wastes has become a research topic in the field of construction and environmental protection. focus; [0003] At present, there are many types ...
