Operation method of carbon dioxide carbonized brick body manufacturing device

Abstract

The invention discloses an operation method of a carbon dioxide carbonized brick body manufacturing device, and belongs to the field of civil engineering brick manufacturing. The two processes of pre-carbonization and secondary carbonization are specially set, so that after the shape and the strength of a brick body are temporarily stabilized, demolding is smoothly completed, and the strength is rapidly increased. All systems in the device work coordinately and orderly according to the method, so that charging, compaction forming and brick mold conveying are conducted at the same time, brick material adding and uniform mixing are conducted in the pre-carbonization process, and the brick body manufacturing and conveying efficiency is greatly improved; an upper conveying belt and a lower conveying belt rotate through a rotating shaft, brick bodies are demolded through spring limiters in brick molds, and brick body demolding and efficient cyclic utilization of the empty brick molds are achieved through electromagnet adsorption and releasing and conveying of the conveying belts. According to the brick manufacturing method, low-concentration carbon dioxide and construction waste are utilized, the carbon dioxide in a carbonization cavity can be pumped into a storage bin through an exhaust fan after carbonization, carbon dioxide gas is recycled, tail gas emission is reduced, environmental protection is facilitated, and the brick manufacturing cost is reduced.

Description

Technical field[0001]The invention belongs to the category of civil engineering bricks, and specifically relates to an operation method of a carbon dioxide carbonized brick body making 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. my country has produced a total of 20 billion m in the past 50 years3And these clay bricks will be discarded with the demolition, accounting for about 30%-50% of the construction waste. The sources of discarded clay bricks are very rich. These discarded bricks are transported to the suburbs or villages without any treatment. Some are directly used as filling materials for general roads and subgrades, and some are processed in open-air stacking or landfilling. Good application of construction waste. These treatment methods not only occupy a large amount of land, but also spill a large amount of dust and ...
