This utility model discloses a microbial carbon fixation enhanced recycled aggregate device with stirring function, including an air inlet device, a liquid inlet device, a reaction vessel body, and a collection device. The air inlet device includes a vacuum pump and a carbon dioxide cylinder, with an inlet pipe connected to the carbon dioxide cylinder. The inlet pipe is equipped with a thickened valve, a valve handwheel, a pressure gauge, and an inlet valve. The vacuum pump is connected to the side of the reaction vessel body via a flange. Thus, the heating furnace performs a carbonization reaction by mixing microbial slurry, calcium source solution, and recycled aggregate in the reaction vessel. The recycled aggregate is placed in the reaction vessel, and the device controller controls the introduction of carbon dioxide, the spraying of the solution, and the stirring of the recycled aggregate within the reaction vessel. After carbonization, the aggregate enters the aggregate collection area. This device achieves more uniform carbonization of the recycled aggregate, improves the modification effect of microbial enhanced recycled aggregate, and is suitable for enhancing recycled aggregate with carbon-fixing bacteria.

This invention relates to the technical field, and more particularly to a carbonization production system for wooden flower stand panels, comprising: a conveying mechanism and a carbonization mechanism disposed on the conveying mechanism, wherein the carbonization mechanism includes a spray gun assembly movable and rotatably disposed on the conveying mechanism, a converging assembly rotatably disposed at the flame end of the spray gun assembly, and an adjusting assembly disposed between the spray gun assembly and the converging assembly; the conveying mechanism continuously conveys the panels within the carbonization mechanism, and the spray gun assembly, in conjunction with the converging assembly, focuses the flame onto the carbonization area of ​​the panel. When grooves and / or ridges are formed on the surface of the panel, causing undulations, the adjusting assembly forces the spray gun assembly to move and rotate, adjusting the temperature of the flame emitted by the converging assembly. Simultaneously, the adjusting assembly forces the converging assembly to move and rotate, adjusting the distance and orientation between the emitted flame and the undulating surface of the panel. This solves the problems of flame dispersion, uneven carbonization and inconsistent depth, and the tendency to create blind spots in existing carbonization systems.
