Description

Technical Field

[0001] This utility model relates to the field of aerated concrete block preparation technology, and more specifically, to an autoclaved aerated concrete block preparation device based on dynamic pressure regulation. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a high-performance building material made through a special process. They are lightweight, high-strength, and have good thermal insulation properties. In the production process, concrete is mixed with a specific proportion of foaming agent, stirred, poured into molds, and then placed in an autoclave.

[0003] Patent authorization announcement number CN222904445U discloses an autoclaving device for the production of autoclaved aerated concrete blocks, including a main vessel body. A sealing component for sealing the main vessel body is provided on one side of the main vessel body. A cleaning component is provided inside the main vessel body. When the main vessel body is cooling, an electric push rod is activated, thereby driving the bottom plate to move downward. During the downward movement of the bottom plate, the telescopic plate B and the telescopic plate A are ejected to both sides of the bottom plate under the action of the second spring and the first spring, respectively, thereby bringing the side plates and the soft brush into contact with the inner wall of the main vessel body to clean the liquid droplets on the inner wall of the main vessel body, ultimately achieving the effect of facilitating the cleaning of the inner wall.

[0004] However, the steam generator in patent publication number CN222904445U experiences pressure fluctuations during steam output. These pressure fluctuations lead to unstable steam flow, affecting the stability of the internal pressure of the autoclave. Unstable steam pressure can cause internal stress in aerated concrete blocks due to temperature differences during autoclaving, especially when the heating or cooling rate is too fast (exceeding 20°C / hour). This uneven moisture migration within the block can easily lead to lightning-shaped cracks. Therefore, we propose an autoclaved aerated concrete block preparation device based on dynamic pressure regulation to solve the above-mentioned problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1-4 A device for preparing autoclaved aerated concrete blocks based on dynamic pressure regulation includes a base 1, an autoclave 2 fixed on the base 1, a sealing cover 3 hinged to the port of the autoclave 2, and a steam inlet pipe 4 connected to the autoclave 2. An actuator is installed at the end of the steam inlet pipe 4.

[0031] The actuator includes a valve body 6 connected to the steam inlet pipe 4, a valve seat 8 fixedly connected to the valve body 6, a valve stem 9 rotatably connected to the valve seat 8, a valve plate 10 installed on the inner side of the valve body 6 and connected to the bottom end of the valve stem 9, a bracket 12 fixedly connected to the edge of the valve seat 8, and a stepper motor 13 installed on the top of the bracket 12 and whose power output end is connected to the valve stem 9.

[0032] A pressure sensor 14 is installed at the air inlet end of the valve body 6;

[0033] A controller 15 is installed on one side of the base 1;

[0034] It should be noted that, in use, the autoclaved aerated concrete block preparation device based on dynamic pressure regulation first connects the pressure sensor 14 to the steam generator through a pipeline, and uses the steam inlet pipe 4 to transport steam to the autoclave 2. The pressure sensor 14 is used to sense the change in steam pressure in the pipeline and transmits the pressure signal to the controller 15 in real time. The controller 15 compares the received pressure signal with the preset pressure range, and then outputs a control signal to the actuator. The stepper motor 13 on the actuator drives the valve plate 10 to rotate according to the control signal by using its output end in conjunction with the valve stem 9 on the valve seat 8, so as to adjust the opening of the valve plate 10 inside the valve body 6, thereby achieving the purpose of regulating the steam pressure. It has the characteristics of fast response, precise control and good stability, which can ensure the stability of the autoclave pressure inside the autoclave 2 and prevent cracks from appearing in the autoclaved aerated concrete blocks.

[0035] like Figure 4 As shown, a dynamic seal 11 is installed at the junction of the valve seat 8 and the valve stem 9;

[0036] It should be noted that by using the dynamic seal 11 to fill the gap between the valve seat 8 and the valve stem 9, steam leakage can be effectively prevented while ensuring the normal rotation of the valve stem 9.

[0037] like Figure 4 As shown, a coupling is installed between the power output shaft of the stepper motor 13 and the valve stem 9;

[0038] It should be noted that this ensures that the power transmitted by the stepper motor 13 can be properly transmitted to the valve stem 9.

[0039] like Figure 1 , Figure 2As shown, a first flange 5 is fixedly connected to the end of the steam inlet pipe 4, and a second flange 7 is integrally formed at both ends of the valve body 6. One of the second flanges 7 is connected to the first flange 5 by bolts, and a sealing gasket is installed between the first flange 5 and the second flange 7. A third flange 16 is integrally formed at both ends of the pressure sensor 14. One of the third flanges 16 is connected to the second flange 7 away from the first flange 5 by bolts, and a sealing gasket is installed between the second flange 7 and the third flange 16.

[0040] It should be noted that this facilitates the assembly of the steam inlet pipe 4, valve body 6, and pressure sensor 14, while ensuring the sealing of the connection between the steam inlet pipe 4, valve body 6, and pressure sensor 14.

[0041] like Figure 1 , Figure 2 As shown, the output terminal of the pressure sensor 14 is electrically connected to the input terminal of the controller 15, and the output terminal of the controller 15 is electrically connected to the input terminal of the stepper motor 13.

[0042] It should be noted that the pressure sensor model 14 can be HALO-FB-WE, and the controller model 15 can be EHR-PE20.

[0043] In use: First, connect the pressure sensor 14 to the steam generator through a pipe. Use the steam inlet pipe 4 to deliver steam to the autoclave 2. The pressure sensor 14 is used to sense the change in steam pressure in the pipe and transmit the pressure signal to the controller 15 in real time. The controller 15 compares the received pressure signal with the preset pressure range and then outputs a control signal to the actuator. The stepper motor 13 on the actuator drives the valve plate 10 to rotate according to the control signal by using its output end in conjunction with the valve stem 9 on the valve seat 8. This adjusts the opening of the valve plate 10 inside the valve body 6 to achieve the purpose of regulating the steam pressure. It has the characteristics of fast response, precise control and good stability, which can ensure the stability of the autoclave 2 internal autoclave pressure.

[0044] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
