Method for preparing novel sintered brick from construction waste

Abstract

The invention discloses a method for preparing a novel sintered brick from construction waste, which comprises the following steps: 1. collecting construction waste, and removing impurities from the construction waste for later use; 2, the construction waste is thrown into a crushing mechanism to be crushed, and the construction waste obtained after extrusion crushing falls into a conveying mechanism through a discharging hopper; the crushed construction waste is conveyed into a mixing mechanism through the conveying mechanism; 3, water is added into the sintered brick mixed raw material, stirring is carried out to form brick body pug, and the brick body pug is prepared into a sintered brick blank; and step 4, the sintered brick blank is put into a brick kiln for roasting, drying and shaping are carried out, according to the novel sintered brick preparation device, construction waste and sintered brick raw materials are stirred and mixed through a second mixing frame, meanwhile, a first mixing frame rotates while rotating around a rotary disc, the sintered brick preparation raw materials can be fully mixed and stirred to be uniform, and therefore the quality is better when the rawmaterials are used for preparing sintered bricks.

Description

technical field [0001] The invention relates to the technical field of sintered brick preparation, in particular to a method for preparing a new sintered brick from construction waste. Background technique [0002] Traditional sintered bricks, that is, all the bricks used for masonry load-bearing and non-load-bearing walls made of clay, shale, coal gangue or fly ash as raw materials after molding and high-temperature roasting are collectively referred to as sintered bricks. Divided into sintered clay bricks, sintered fly ash bricks, sintered shale bricks, etc. Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. Construction waste is used as a raw material for the preparation of fired bricks, which effectively solves the problem of construction waste recycling and new materials for fir...

Problems solved by technology

Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. Construction waste is used as a raw material for the preparation of fired bricks, which effectively solves the problem of construction waste recycling and new materials for fired bricks. In the process of preparing fired bricks from construction waste in the existing process, the treatment effect of construction waste is not good, and it is impossible to treat construction waste. Effective pulverization and thorough mix
