Problems solved by technology

Compared with domestic waste, the reuse of construction waste in my country has not attracted much attention. Most of the construction waste is only manually sorted out of metal materials, and the rest are transported to the suburbs for stacking or landfill. Burying will consume a lot of construction funds such as land acquisition and garbage removal. At the same time, the scattering and dust in the process of cleaning and stacking will aggravate environmental pollution.

Embodiment Construction

[0022] The present invention is described in further detail below:

[0023] The present invention provides a kind of production method of construction waste brick making, and this technology comprises the following steps:

[0024] A. Pretreatment: First, use mechanical knocking, chiseling, and shearing to reduce large pieces of construction waste to 0.5m, cut off excessively long steel bars to prevent damage to the conveyor belt, and sort and remove non-constructive materials to obtain small pieces construction waste;

[0025] B. Feeding: transport small pieces of construction waste to the feeding belt of the primary crusher through the loader;

[0026] C. Primary crushing: The primary crushing is carried out through the jaw crusher, and the 0.5m large stones in the small construction waste are broken into small stones of 80mm-180mm;

[0027] D. Iron removal: the steel bar in the material is separated by a magnetic separation device;

[0028] E. Secondary crushing: The mate...

Abstract

The invention provides a production method for making bricks from building waste. The building waste can be recovered effectively and made into bricks by means of the method, so that resource utilization of the building waste is achieved, and environmental pollution caused by stacking or landfill of the building waste is avoided. The process comprises the following steps: A, pre-treatment: firstly, reducing the building waste to 0.5m; B, charging; C, primary crushing: carrying out primary crushing through a jaw crusher; D, deironing; E, secondary crushing: conveying a material without iron toan impact crusher to be crushed secondarily; F, screening: screening the secondarily crushed material to different specifications through a vibrating screen; G, preparing brick-making raw materials: proportioning the screened regenerated fine aggregate in a proportion as follows: 65% of mud powder, 15% of cement and 20% of regenerated aggregate; H, brick making: conveying the uniformly stirred rawmaterial to a hopper of a brake maker; and I, maintaining: transferring ecological bricks produced in the brick maker to a maintaining region to be maintained.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of construction waste, in particular to a production method for making bricks from construction waste. Background technique [0002] With the acceleration of the pace of modernization in our country, construction waste is increasing day by day. Compared with domestic waste, the reuse of construction waste in my country has not attracted much attention. Most of the construction waste is only manually sorted out of metal materials, and the rest are transported to the suburbs for stacking or landfill. Burying will consume a lot of construction funds such as land acquisition and garbage removal. At the same time, the dust and dust in the process of removal and stacking will aggravate environmental pollution. How to properly dispose of these construction wastes and realize their resource utilization without polluting the environment is a problem that we urgently need to solve. Conten...
