Description

Technical Field

[0001] The utility model belongs to the technical field of autoclaving devices, and particularly relates to a high-temperature autoclaving device for autoclaved aerated bricks. Background Art

[0002] Autoclaved aerated bricks are aerated concrete blocks produced by high-temperature autoclaving equipment technology. They have the characteristics of light weight, good heat insulation and heat preservation performance. With the rapid development of the construction industry, the building area is getting larger and the number of floors is increasing. Therefore, people's requirements for buildings are getting higher and higher. Traditional concrete structures are relatively heavy. In comparison, aerated bricks are treated at high temperature and high pressure for the formed aerated bricks, so that the moisture in the bricks is fully evaporated, making the aerated bricks lighter in weight and more stable in structure. When manufacturing autoclaved aerated bricks, autoclaving and curing the autoclaved aerated bricks is a very important process, which is related not only to the performance of the product, but also to production efficiency and energy consumption.

[0003] At present, factories mainly use autoclaves to carry out high-temperature autoclaving and curing treatment on autoclaved aerated bricks. However, in the process of use, the existing autoclaves need to heat water through heating pipes beside them to generate steam first, and then pour the steam into the autoclave. The operation is very troublesome. Moreover, the cut autoclaved aerated bricks are stacked and sent into the autoclave together. The high-temperature autoclaving effect of the autoclaved aerated bricks stacked inside is not good, and a lot of heat cannot be transmitted to the inside, so that the cement and foaming agent cannot undergo a chemical reaction to generate a large amount of gas, resulting in holes formed inside the bricks, thus reducing the weight of the bricks.

[0023] Refer to Figures 1 to 5 , the present utility model discloses a high-temperature autoclaving device for autoclaved aerated concrete blocks, including: a kettle body 1, a kettle lid 2, and a fixing frame 3; the bottom of the kettle body 1 is supported by a support base 4, the outer shell of the kettle body 1 is layered and an internal sealing cavity 11 is formed, four fixed rods 12 are arranged inside the kettle body 1, the fixing frame 3 is slidably installed on the fixed rods 12, the kettle lid 2 is arranged at the right end of the kettle body 1, a steam pipe 13 is arranged below the kettle body 1 and connected to the sealing cavity 11, and the pipe orifice is arranged at the bottom of the kettle body 1 near the kettle lid 2. An air duct 14 is arranged above the sealing cavity 11. One end orifice of the air duct 14 is arranged at the middle position of the upper end of the kettle body 1 to communicate with the sealing cavity 11, and the other end orifice is arranged at the center position on the left side of the kettle body 1 and passes through the sealing cavity 11 and is connected to the inside of the kettle body 1. An exhaust pipe 15 is arranged above the kettle body 1 near the kettle lid 2.

[0024] Refer to Figure 1 、 Figure 3 、 Figure 4As shown, the main body of this device is an autoclave, which is a pressure vessel and is widely used in the autoclave curing process of various materials. Its function is to promote the discharge of moisture and air inside the material under high pressure and high temperature conditions, thereby making it more compact, increasing thermal conductivity, accelerating the heating speed, and improving processing efficiency. In addition, the autoclave is also suitable for sterilization and disinfection treatments, providing an ideal treatment environment for items that need to be aseptically treated in a high-temperature and high-pressure environment. In terms of chemical reactions, the high-temperature and high-pressure environment of the autoclave can promote chemical reactions on the surface or inside of the item, accelerate the impregnation speed, improve the impregnation effect, and thus enhance the quality of the processed product. This device mainly achieves a high-temperature and high-pressure environment through steam. The steam is input from the steam pipe 13, and the steam pipe 13 is connected to the sealed cavity 11. The steam first enters the sealed cavity 11. When the steam fills the entire sealed cavity 11, it is transmitted to the inside of the autoclave body 1 through the air guide pipe 14, filling the entire internal cavity, and performing autoclave curing treatment on the aerated bricks. Finally, the steam inside the autoclave body 1 is discharged through the exhaust pipe 15.

[0025] In this embodiment, an intake valve 131 is provided on the steam pipe 13, a gas guide valve 141 is provided on the air guide pipe 14, and an exhaust valve 151 is provided on the exhaust pipe 15.

[0026] Refer to Figure 4 As shown, first, all the valves in the device are closed. Open the intake valve 131, and the steam enters the sealed cavity 11 from the steam pipe 13. When the steam fills the sealed cavity 11, then open the gas guide valve 141, and the steam flows from the sealed cavity 11 to the inside of the autoclave body 1. When the curing is completed, close the intake valve 131 and the gas guide valve 141 in sequence, and open the exhaust valve 151, so that the steam inside the autoclave body 1 can be discharged from the exhaust pipe 15.

[0027] In this embodiment, a safety valve 102, a pressure gauge 103, and a thermometer 101 are installed on the outer wall of the autoclave body 1. The safety valve 102 is arranged at a position slightly to the left of the upper end of the autoclave body 1. The pressure gauge 103 is arranged at the upper end of the autoclave body 1 and is located in the middle position between the air guide pipe 14 and the exhaust pipe 15. The thermometer 101 is arranged on the side wall of the autoclave body 1.

[0028] Refer to Figure 1 、 Figure 2As shown, the safety valve 102 is used to control the pressure inside the kettle body 1 and protect the safety of the system. When the pressure in the kettle body 1 exceeds the specified safety value, the safety valve 102 will automatically open and quickly discharge part of the steam, thereby reducing the system pressure. This process ensures that the system will not be damaged or suffer safety accidents due to excessive pressure. When the pressure returns to the allowable range, the safety valve 102 will automatically close to maintain the stable operation of the system. The pressure gauge 103 is used to monitor the pressure value inside the kettle body 1, and the thermometer 101 is used to monitor the temperature inside the kettle body 1, so that the kettle body 1 reaches a suitable high-temperature and high-pressure environment for steam curing the aerated bricks.

[0029] In this embodiment, the fixing rods 12 are distributed in a square shape inside the kettle body 1. The length of the fixing rods 12 is the same as the inner length of the kettle body 1. The fixing rods 12 are provided with sliding grooves 121. Among them, for the two fixing rods 12 arranged above, the sliding grooves 121 are arranged at the bottom, and for the two fixing rods 12 arranged below, the sliding grooves 121 are arranged at the upper part.

[0030] In this embodiment, the fixing frame 3 is divided into three layers, namely the top layer 31, the middle layer 32, and the bottom layer 33. The upper surface of the top layer 33 is provided with two sliding rods 301, and the lower surface of the bottom layer is provided with two identical sliding rods 301. The sliding rods 301 on the top layer 31 of the fixing frame 3 match the sliding grooves 121 arranged above inside the kettle body 1, and the sliding rods 301 on the bottom layer 33 match the sliding grooves 121 arranged below inside the kettle body 1. The fixing frame 3 is installed on the fixing rods 12 through the sliding rods 301.

[0031] Refer to Figure 1 、 Figure 3 、 Figure 5 As shown, this device separates and places the aerated bricks to avoid stacking the bricks together so that the inner bricks cannot be cured. The fixing frame 3 is divided into three layers, and the bricks are laid flat on each layer. Then, align the four sliding rods 301 with the sliding grooves 121, push the entire fixing frame 3 into the kettle body 1, and then close the kettle lid 2 to input steam for autoclave curing treatment.

[0032] In this embodiment, the length of the fixing frame 3 is the same as the length of the fixing rods 12. A number of round holes 302 are evenly opened on the top layer 31, the middle layer 32, and the bottom layer 33 of the fixing frame 3.

[0033] Refer to Figure 1 、 Figure 3As shown in the figure, steam is directly introduced through the steam pipe 103 without generating heated water on the side, which is faster. The steam first fills the entire sealed cavity 11 to preheat the outer shell of the autoclave body 1, and then is discharged into the autoclave through the air duct 104 to steam-cure the bricks, forming irregular and fine bubbles inside the bricks, resulting in a dense and delicate pore structure, improving the compressive strength, frost resistance and impermeability of the bricks, and reducing the weight of the bricks. During the steam-curing process, the round holes 302 are conducive to the full contact of steam with the aerated bricks, ensuring that all aerated bricks can be cured, avoiding the situation of insufficient steam-curing of the bricks, improving the efficiency of steam-curing, and ensuring the quality of the autoclaved aerated bricks produced. And it is conducive to reducing environmental pollution.
