Description

Technical Field

[0001] The invention relates to the technical field of autoclaving equipment, in particular to an automated autoclaving equipment for autoclaving aerated concrete blocks. Background Art

[0002] The production of autoclaved aerated concrete blocks has abundant raw materials, especially fly ash as raw material, which can comprehensively utilize industrial waste residue, control environmental pollution, and not damage arable land, while creating good social and economic benefits. It is an ideal wall material to replace traditional solid clay bricks. Aerated concrete products have become an important component of new building materials and have broad market development prospects.

[0003] The manufacturing process is based on the physical and chemical reactions between the slurries. The main raw materials are siliceous materials (sand, fly ash, and silicon-containing tailings, etc.) and calcareous materials (lime, cement), mixed with a gas-generating agent (aluminum powder), and stirred with water. Pores are formed by chemical reactions. Furthermore, as the temperature increases, the volume increases (the volume of hydrogen increases from 0°C to 40°C), which inevitably causes the mixed slurry to expand. Aerated blocks that are not steam-cured will have insufficient density and strength, and will not meet national standards.

[0004] The operation and control of existing autoclave curing are all done manually by workers. Since the production is in a high temperature and high pressure environment, the workers work in a harsh environment, with high labor intensity, which is also easy to cause harm to the workers. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an automated autoclaving equipment for autoclaved aerated concrete blocks, which solves the problems of traditional manual operation in the autoclaving curing process, such as the harsh environment and high labor intensity, and the proneness to production accidents and the disadvantages of being detrimental to personal safety.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automated autoclaving device for autoclaved aerated concrete blocks, comprising an autoclave and a controller, wherein the autoclave inlet and outlet are provided with a sealing cover, the outer surface of the sealing cover is provided with an opening and closing mechanism, the autoclave and the sealing cover are both threadedly connected to a locking mechanism, and the inner wall of the autoclave is fixedly connected with uniformly distributed photoelectric sensors, pressure sensors, and temperature sensors;

[0010] Preferably, the outer wall of the servo motor is fixedly connected to a motor base.

[0012] Preferably, the platform is equipped with a human-computer interaction interface for displaying the real-time position of the semi-finished concrete blocks, and for setting and controlling the internal pressure and temperature values ​​of the autoclave through a controller.

[0013] Preferably, the operation method of the automated autoclave equipment comprises the following steps:

[0014] Step 1: The human-machine interface of the operating platform controls the winch through the controller to pull the semi-finished concrete block into the autoclave, and simulates the real-time position of the semi-finished concrete block inside the autoclave based on the real-time feedback data from the photoelectric sensor. When the semi-finished concrete block approaches the predetermined position, the pulling is stopped to stop the movement due to the friction force;

[0015] Step 2: The controller controls the cylinder to extend and drive the crossbeam to rise, which causes the rocker arm to rotate under the action of the rotating shaft, thereby driving the sealing cover to rotate to the inlet and outlet of the autoclave and seal it;

[0016] Step 3: The controller controls the servo motor to start and drive the locking wheel to rotate, thereby driving the locking ring to rotate, so that the locking ring is simultaneously threadedly connected to the autoclave and the sealing cover, thereby achieving the purpose of auxiliary sealing;

[0017] Step 4: After sealing, the controller controls the steam to enter the autoclave, and controls the internal pressure and temperature of the autoclave to reach the preset values ​​according to the data fed back by the pressure sensor and the temperature sensor, and then the curing can be carried out;

[0032] The controller controls the winch to pull the semi-finished concrete blocks into the autoclave 1, and simulates the real-time position of the semi-finished concrete blocks inside the autoclave 1 according to the real-time feedback data of the photoelectric sensor 13.

After the curing is completed, the controller controls the autoclave 1 to release the pressure. When the pressure and temperature drop to the preset opening value, the servo motor 10 is first controlled to reverse to separate the locking ring 9 and the sealing cover 3 from each other, and then the cylinder 8 is controlled to contract, driving the sealing cover 3 to flip upward to be fully opened.

[0037] The controller then controls the servo motor 10 to start driving the locking wheel 11 to rotate, thereby driving the locking ring 9 to rotate, so that the locking ring 9 is simultaneously threadedly connected to the autoclave 1 and the sealing cover 3, thereby achieving the purpose of auxiliary sealing.

[0038] A motor base 12 is fixedly connected to the outer wall of the servo motor 10 .

[0039] The motor base 12 is used to fix the servo motor 10 .

When the semi-finished concrete block approaches the predetermined position, the pulling is stopped to stop the movement due to the friction force;

[0047] Step 2: The controller controls the cylinder 8 to extend and drive the crossbeam 7 to rise, which causes the rocker arm 4 to rotate under the action of the rotating shaft 5, thereby driving the sealing cover 3 to rotate to the inlet and outlet of the autoclave 1 and seal it;
