An operation method for making bricks by using a carbon dioxide carbonization device

Abstract

The invention discloses an operation method for making a brick body by using a carbon dioxide carbonization device, and belongs to the field of civil engineering brick making. In the present invention, two processes of pre-carbonization and secondary carbonization are ad hoc, and after temporarily stabilizing the shape and strength of the brick body, demoulding and rapid strength growth are successfully completed. All systems in the device work in an orderly manner according to this method, so that loading, compaction and brick mold transmission are carried out at the same time, and brick materials are added and mixed in the pre-carbonization process, which greatly improves the brick production and transmission efficiency; up and down The conveyor belt rotates through the rotating shaft, and the brick body is demoulded through the spring stopper in the brick mould, and is absorbed and released by the electromagnet and conveyed by the conveyor belt, so as to realize the demoulding of the brick body and the efficient recycling of the empty brick mould. This brick-making method utilizes low-concentration carbon dioxide and construction waste. After carbonization, the carbon dioxide in the carbonization chamber can be pumped into the storage bin by the exhaust fan, and the carbon dioxide gas can be recycled to reduce tail gas emissions, which is beneficial to environmental protection and reduces production costs. brick cost.

Description

technical field [0001] The invention belongs to the civil engineering brick making category, and in particular relates to an operation method for making a brick body by using a carbon dioxide carbonization device. Background technique [0002] With the continuous development of urbanization, a large number of urban and rural buildings have been demolished, and many of the demolished buildings are clay bricks. In the past 50 years, my country has produced a total of 20 billion m 3 left and right clay bricks, and these clay bricks will be abandoned along with the demolition, accounting for about 30%-50% of the amount of construction waste. The sources of waste clay bricks are very rich. These waste bricks were transported to the suburbs or villages without any treatment. Some were directly used as filling materials for general road subgrades, and some were disposed of by open-air stacking or landfilling. Good application for construction waste. These disposal methods not on...
