Efficient autoclaved aerated brick device and use method

Abstract

The invention relates to the technical field of aerated concrete block processing, in particular to an efficient autoclaved aerated brick device which comprises a bottom plate, and a support is arranged at the top of the bottom plate; the interior of the bracket is fixedly connected with a device main body; a rotating rod is arranged in the device main body; the top of the rotating rod is fixedly connected with the bracket; the first fan blade and the second fan blade on the flow dividing pipe rotate in different driving directions, and the downward moving rotating direction of the aerated bricks is opposite to the rotating directions of the first fan blade and the second fan blade, so that steam can be fully gathered to the position of the central aerated brick in the specific implementation process and continuously flows; therefore, the problem that heat energy is wasted due to steam accumulation is solved, meanwhile, the continuously flowing steam can fully collide and make contact with the aerated bricks to enable the aerated bricks to be heated evenly, and the problems that the temperature difference is too large due to uneven heating, and the aerated bricks have cracks are solved.

Description

technical field [0001] The invention relates to the technical field of aerated concrete block processing, in particular to a high-efficiency autoclaved aerated brick device and a use method. Background technique [0002] Aerated brick is the abbreviation of autoclaved aerated concrete block, which is aerated concrete block produced by high-temperature autoclaved process. Aerated brick has the characteristics of light capacity, good overall performance, and small inertial force during earthquakes. When producing aerated bricks, it is necessary to use an autoclave to apply saturated steam to the concrete. [0003] When the existing forming device for the production of aerated bricks is in use, the steam is usually injected through the injection pipe along the holes of the aerated bricks, and the amount of steam entering the aerated bricks is uneven, resulting in uneven heating inside the aerated bricks and affecting the quality of the finished product At the same time, due to...

Problems solved by technology

[0003] When the existing forming device for the production of aerated bricks is in use, the steam is usually injected through the injection pipe along the holes of the aerated bricks, and the amount of steam entering the aerated bricks is uneven, resulting in uneven heating inside the aerated bricks and affecting the quality of the finished product At the same time, due to the large amount of moisture adsorbed in the pores of the aerated bricks, there is a certain difference between the temperature of the pores near the air injection port and the temperature of the pores at the end far away from the air injection ports, and the bond strength of the incompletely cured aerated bricks is weak. , when the temperature difference between the pores at both ends of the aerated brick is too large, there will be cracks in the aerated brick, which will eventually lead to the strength of the aerated brick produced far below the predetermined value;

[0004] At the same time, the steam has poor fluidity in the autoclaving chamber and easily accumulates on the edge of the device, which not only wastes the heat energy in the steam, but also easily produces water droplets when the steam contacts the device wall, which affects the subsequent autoclaving process of the aerated brick;
