Embodiment 1

[0056] In order to more clearly demonstrate the operation method and working principle of the brick making device of the present invention, on the basis of the aforementioned brick making device and operating steps, further supplementary examples are carried out. Assuming that the brick mold 2 used in this method is an iron material, there are 5 brick molds 2 on the conveyor belt with spring stoppers and sensors, the inner size of the brick mold 2 is 240mm*115mm*120mm, and the thickness of the brick body is prefabricated The length and width of the pressure head of the hydraulic device 33 are 240mm*115mm. Assuming that the brick mold 2 is 220mm high, the distance between the lower conveyor belt 302 and the conveyor belt C10 is 400mm.

[0057] Its working principle: when working, clay brick fines and magnesium hydroxide solution are mixed in the mixing chamber 42 after a certain period of time and then stirred evenly. The discharge machine 44 works with the cutting plate 4 to o...

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...
