Description

Technical Field

[0001] This invention relates to flow fields in the field of pressure vessels, and in particular to a flow field equalization device inside a high-temperature, high-pressure sealed container. Background Technology

[0002] Currently, closed containers, while maintaining high temperature and pressure, require that the temperature difference at various points within the container be kept within technical requirements, and that pressure be kept stable. Structures such as orifice plates, conical orifice plates, flow guides, and diverter pipes are typically installed inside the container to create multiple inlets and uniform outlets for the medium, reducing the velocity gradient. However, due to various reasons, it is difficult to achieve the required temperature difference. External interference also struggles to solve the problem of maintaining internal pressure. Therefore, for high-temperature, high-pressure closed containers, relying on external factors to influence the internal space is unlikely to achieve the designed temperature and pressure requirements.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] Simply using ordinary or conical orifice plates to improve the uniformity of the temperature field inside the tank cannot guarantee that the temperature and pressure fields of different parts of the tank remain uniform, and cannot prevent local overheating or cold spots.

[0005] There is an urgent need for a flow field equalization device to achieve rapid and uniform distribution of temperature and pressure inside the tank, thereby improving the finished product qualification rate, reducing energy consumption, and lowering operating costs. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and address the issues of hot and cold spots in high-temperature, high-pressure sealed containers, this application provides a flow field equalization device for the internal flow field of such containers. This device rotates the contents within the container and uses a turbulence mechanism to regulate the airflow distribution, ensuring uniform temperature and pressure across the container. This prevents localized overheating or cold spots, achieving rapid and uniform temperature and pressure distribution within the container. Under the same heating power, this accelerates the temperature rise rate, improves thermal efficiency, and solves the technical problem of flow field uniformity in high-temperature, high-pressure sealed containers.

[0086] This application provides a flow field equalization device for the internal environment of a high-temperature, high-pressure sealed container, which solves the problem of hot and cold spots in existing high-temperature, high-pressure sealed containers. In this device, the container rotates inside the tank, and a turbulence mechanism is set to adjust the airflow distribution inside the tank, so that the temperature and pressure fields of all parts of the tank are kept uniform. The uniform flow field drives the rapid transfer of heat inside the tank, avoiding hot and cold spots, achieving flow field equalization, accelerating the temperature rise rate under the same heating power, and improving thermal efficiency.

[0087] According to the instruction manual Figure 1-13 As shown, a flow field equalization device inside a high-temperature and high-pressure sealed container includes a trolley 200, a transmission mechanism 300, a clutch 400, a flow disturbance mechanism 500, a frequency-modulated motor 600, a sealed chamber 700, a pressure-holding chamber 800, and a pressurizing device 900.

[0088] The trolley 200 is housed inside the tank 100. A rotating cage 220 is installed on the trolley 200 and is driven to rotate by a rotating mechanism 240. A tray 230 is suspended on the rotating cage 220 and rotates with the rotating cage 220. The tray 230 contains a container. The container rotates and changes position inside the tank 100 to make the temperature and pressure of the container in different positions uniform.

[0089] The transmission mechanism 300 is located at the closed end of the tank 100 and is used to provide power for the rotation of the rotating cage 220;

[0090] The clutch 400 is a split coupling, with one end connected to the output end of the transmission mechanism 300 and the other end connected to the input end of the rotating mechanism 240.

[0091] The flow disturbance mechanism 500 has a drive shaft 520 that passes through the end cap of the closed end of the tank 100. At the extension end of the drive shaft 520 located inside the tank 100, there are blades 510, a drive gear 540 and a sealing ring 550. The blades 510 serve as flow field regulating elements to regulate the distribution of airflow or steam flow inside the tank 100, so that the temperature and pressure of the flow field inside the tank 100 are uniform. The drive gear 540 is connected to the input end of the transmission mechanism 300 and is used to drive the transmission mechanism 300.

[0092] The frequency-modulated motor 600 is connected to the extension end of the drive shaft 520 located outside the tank 100, and is used to drive the drive shaft 520 to rotate, drive the blade 510 to rotate, and provide power to the transmission mechanism 300.

[0093] The sealing chamber 700 is located outside the end cap of the closed end of the tank body 100 and is fitted onto the drive shaft 520 to seal the drive shaft 520.

[0094] The pressure-holding chamber 800 is located outside the sealed chamber 700. A sealing ring 550 is provided in the inner cavity adjacent to the sealed chamber 700 and the pressure-holding chamber 800 to stabilize the pressure inside the tank 100.

[0095] The pressurizing device 900 is connected to the pressure holding chamber 800. The pressure of the pressurizing device 900 acts on the outside of the sealing ring 550, maintaining the pressure balance on both sides of the sealing ring 550, enhancing the sealing performance of the sealing ring 550, preventing pressure leakage inside the tank 100, and maintaining the stability of the internal pressure of the tank 100.

[0096] There are three methods for achieving flow field equalization: First, the drive shaft 520 is not equipped with blades 510, the frequency-modulated motor 600 drives the drive shaft 520, and the drive shaft 520 is connected to the rotating mechanism 240 via the transmission mechanism 300 and the clutch 400, causing the rotating cage 220 to rotate, while the contents in the tray 230 rotate independently; Second, the clutch 400 is disengaged, the drive shaft 520 is equipped with blades 510, and the frequency-modulated motor 600 drives the drive shaft 520, causing the blades 510 to rotate; Third, the drive shaft 520 is equipped with blades 510, the frequency-modulated motor 600 drives the drive shaft 520, causing the blades 510 to rotate; at the same time, the transmission mechanism 300 is connected to the rotating mechanism 240 via the clutch 400, causing the rotating cage 220 to rotate, and the contents in the tray 230 also rotate.

[0099] Because the tank body 100 is equipped with a flow disturbance mechanism 500 with blades 510 as flow field adjustment elements, when the blades 510 rotate, they can adjust the airflow or steam flow distribution inside the tank body 100, thereby making the temperature and pressure of the flow field inside the tank body 100 uniform, avoiding hot spots and cold spots, solving the problem of hot spots and cold spots in high temperature and high pressure sealed containers, and improving the finished product qualification rate.

[0101] Because the uniform flow field drives the rapid transfer of heat within the tank 100, avoiding hot and cold spots, the temperature rise rate is accelerated, energy consumption is reduced, and thermal efficiency is improved under the same heating power.

The bolt holes 830 match the threaded holes 740 on the sealing chamber 700, and the pressure-holding chamber 800 is connected to the sealing chamber 700 by bolts.

[0124] In this embodiment, the sealing chamber 700 and the pressure-holding chamber 800 are integrally machined to form the inner hole of the inlaid sealing ring 550, and then divided to form sealing hole I 710 and sealing hole II 820, to ensure the coaxiality of the inner hole of the inlaid sealing ring 550.

[0125] As a conventional technical choice, the pressurization device 900 is an automatically controlled pressurization device. In this embodiment, an air compressor is used.

[0126] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0127] Since a connecting hole 840 is provided radially in the pressure holding chamber 800 to connect to the pressurizing device 900, when the pressurizing device 900 is started, the pressure inside the pressure holding chamber 800 is stable, and the pressure on both sides of the sealing ring 550 is balanced, thereby stabilizing the pressure inside the pressure holding chamber 800, enhancing the sealing performance of the transmission shaft 520, and ensuring the smoothness of the transmission.

[0128] In this embodiment, the high-temperature, high-pressure sealed container is a shoe vulcanizing tank, containing rubber soles or rubber shoes. It is a pressure vessel used for vulcanizing rubber soles or rubber shoes, with a temperature of 130-150°C and a pressure of 0.8-1.2 MPa. After the rubber soles or rubber shoes are placed in the tank, the tank door is sealed. Heat is transferred to the rubber soles or rubber shoes through heat conduction and heat convection via steam or electric heating, causing the rubber molecules to undergo a cross-linking vulcanization reaction, forming a three-dimensional network structure, thereby improving the elasticity, wear resistance, and strength of the sole.
