Description

Technical Field

[0001] This utility model relates to the field of pressure controller technology, specifically to an intelligent control mechanism for pressure vessels that is easy to inspect and maintain. Background Technology

[0002] The pressure vessel controller is a core device ensuring the safe operation of pressure vessels. It integrates sensors for pressure, temperature, and liquid level with an intelligent control module, enabling real-time monitoring of key parameters within the vessel. It processes data via a PLC or microcontroller, automatically triggering protective actions such as safety valve venting and cooling system activation when the pressure exceeds a threshold. Simultaneously, it provides audible and visual alarms, supports manual or automatic mode switching, and can preset pressure regulation curves to adapt to the dynamic operating conditions of equipment such as reactors and gas storage tanks. Some models include data storage and remote transmission capabilities for easy tracing of operational records.

[0003] In the prior art, such as the explosion-proof pressure controller with application number 202322593390.5, there is a pressure controller body, a limit plate is provided on the top of the pressure controller body, a limit mechanism is provided inside the pressure controller body, and an adjustment mechanism is provided inside the pressure controller body.

[0004] However, the core components (sensors, actuators, etc.) of traditional pressure vessel controllers are integrated and packaged, requiring complete disassembly for maintenance. This results in long maintenance times, high costs for unplanned downtime, and cumbersome and inconvenient operation when disassembling the pressure vessel controller housing during maintenance.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was implemented based on the existing pressure controller. Utility Model Content

[0007] The purpose of this utility model is to provide an intelligent control mechanism for pressure vessels that is easy to inspect and maintain, so as to solve the problem of long inspection and maintenance time and inconvenience in maintenance mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An intelligent control mechanism for pressure vessels that is easy to inspect and maintain includes a controller housing. A display screen is located in the middle of the front side of the controller housing, and a warning light is located below the display screen. A connecting pipe is connected to the upper right side of the controller housing, and the connecting pipe is connected to the pressure vessel pipeline through a flange. Several plugs are located on the upper left side of the controller housing. A control module, a sensing module, and an execution module are installed inside the controller housing, and the control module, sensing module, and execution module are all independent modules. A movable cover is located on the rear side of the controller housing, and the movable cover has an up-and-down moving structure.

[0010] Preferably, the control module, sensing module, and execution module are fixed together via aviation connectors.

[0011] Using the above technical solution, the control module, sensing module and execution module are fixed by aviation joints, which improves disassembly efficiency compared to traditional welding connections. When a single module is being repaired, the entire structure does not need to be disassembled, thus shortening the maintenance time.

[0012] Preferably, the controller housing has heat dissipation vents on both the left and right sides, and dust filters are provided inside the heat dissipation vents.

[0013] By adopting the above technical solution, the heat dissipation vents of the controller housing, together with the inner dust filter, can intercept some dust, avoid short circuits in the module caused by dust accumulation, and adapt to dusty working conditions around pressure vessels.

[0014] Preferably, a drive motor is fixedly installed inside the lower right side of the controller housing, and a first gear is connected and installed at the lower output end of the drive motor, and a second gear is meshed with the rear side of the first gear.

[0015] Using the above technical solution, the drive motor can precisely control the lifting and lowering of the movable cover through the transmission of the first gear and the second gear, which saves operation time compared to manual opening of the cover, and the self-locking property of the gear meshing prevents the movable cover from accidentally slipping off.

[0016] Preferably, a threaded rod is fixedly connected above the second gear, and the right side of the front side of the movable cover is threadedly connected to the outside of the threaded rod. The left side of the movable cover is slidably connected to the slide rod. The threaded rod is rotatably connected to the right side inside the controller housing, and the slide rod is fixedly connected to the left side inside the controller housing.

[0017] The above technical solution features a threaded rod on the right side of the movable cover and a sliding rod on the left side, which reduces the vertical deviation during lifting and lowering, avoids jamming or offset, improves stability compared to a single-rail structure, and ensures that the rear of the outer shell is completely open, facilitating the loading and unloading of internal modules.

[0018] Preferably, connecting rods are fixedly connected to the lower left and right sides of the front of the movable cover, and electrostatic dust removal brush rollers are fixedly installed on the front of the connecting rods. The lifting and lowering of the movable cover drives the electrostatic dust removal brush rollers to clean the filter screen.

[0019] Using the above technical solution, when the movable cover is raised and lowered, the connecting rod drives the electrostatic dust removal brush roller to clean the dust filter screen simultaneously. The dust removal coverage rate is significantly improved compared to manual cleaning, and electrostatic adsorption can remove fine dust, ensuring that the heat dissipation vents remain unobstructed for a long time.

[0020] Preferably, connecting rods are fixedly connected to the lower left and right sides of the front of the movable cover, and electrostatic dust removal brush rollers are rotatably connected to the front of the connecting rods. The lifting and lowering of the movable cover drives the electrostatic dust removal brush rollers to roll and clean the filter screen.

[0021] By adopting the above technical solution, the electrostatic dust removal brush roller is rotatably connected to the connecting rod. During the rolling cleaning, the friction between the brush roller and the dust filter screen is reduced, avoiding wear on the screen surface. At the same time, the rolling contact improves the uniformity of dust removal and solves the problem of incomplete cleaning in certain areas by the fixed brush roller.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the intelligent control mechanism for pressure vessels that facilitates inspection and maintenance,

[0023] 1. Independent modular design improves maintenance efficiency: The control module, sensing module and execution module adopt independent structure and are fixed by aviation connectors, which realizes quick plug-in between modules. During maintenance, there is no need to disassemble the whole device. The faulty module can be removed separately, which shortens the maintenance time compared with the traditional integrated structure. Moreover, the connection stability of aviation connectors ensures that the module can still transmit signals accurately after disassembly and assembly, avoiding secondary debugging.

[0024] 2. The movable cover and dust removal work together to ensure stable operation: The movable cover is automatically raised and lowered by a drive motor, gears, threaded rods, and slide bars. The opening and closing time is reduced from 5 minutes for manual operation to 30 seconds. The rear of the outer shell is fully open, which is convenient for module loading and unloading and internal maintenance. When the movable cover is raised and lowered, the connecting rod drives the electrostatic dust removal brush roller to clean the dust filter screen in sync, which prevents dust from clogging the heat dissipation vents and reduces the maintenance frequency compared to regular manual cleaning.

[0032] Example 1

[0033] Please see Figure 1-5 This utility model provides a technical solution:

[0034] An intelligent control mechanism for pressure vessels that is easy to inspect and maintain includes a controller housing 1.

The control module 18, the sensing module 19, and the execution module 20 are all independent modules. A movable cover 9 is provided on the rear side of the controller housing 1, and the movable cover 9 has an up-and-down moving structure.

[0035] The control module 18, the sensing module 19, and the execution module 20 are fixed together by aviation connectors. Compared with traditional welding connections, the disassembly efficiency is improved. When a single module is inspected, the entire structure does not need to be disassembled, and the maintenance time is shortened.

[0036] The controller housing 1 has heat dissipation vents 8 on both the left and right sides, and dust filters 10 are installed inside the heat dissipation vents 8. Connecting rods 16 are fixedly connected to the lower left and right sides of the front of the movable cover 9, and electrostatic dust removal brush rollers 17 are fixedly installed on the front of the connecting rods 16. The movement of the movable cover 9 drives the electrostatic dust removal brush rollers 17 to clean the dust filters 10. The heat dissipation vents 8 of the controller housing 1, together with the inner dust filters 10, can intercept some dust and avoid short circuits caused by dust accumulation. It is suitable for dusty working conditions around pressure vessels. When the movable cover 9 is raised or lowered, the connecting rods 16 drive the electrostatic dust removal brush rollers 17 to clean the dust filters 10 simultaneously. The dust removal coverage rate is higher than that of manual cleaning, and electrostatic adsorption can remove fine dust, ensuring that the heat dissipation vents 8 are unobstructed for a long time.

[0037] A drive motor 11 is fixedly installed on the lower right side inside the controller housing 1. A first gear 12 is connected to the output end of the drive motor 11, and a second gear 13 is meshed with the rear side of the first gear 12. A threaded rod 14 is fixedly connected above the second gear 13. The right side of the front of the movable cover 9 is threaded to the outside of the threaded rod 14. The left side of the movable cover 9 is slidably connected to the slide rod 15. The threaded rod 14 is rotatably connected to the right side inside the controller housing 1, and the slide rod 15 is fixedly connected to the left side inside the controller housing 1. The drive motor 11 is driven by the first gear 12 and the second gear 13, which can precisely control the lifting and lowering of the movable cover 9. This saves operation time compared to manual opening of the cover. The self-locking property of the gear meshing prevents the movable cover 9 from accidentally slipping off. The right side of the movable cover 9 is threaded to the threaded rod 14, and the left side is slidably connected to the slide rod 15. This reduces the vertical deviation during lifting and lowering, avoids jamming or offset, and improves the stability compared to the single-rail structure. This ensures that the rear side of the housing is completely open, making it easy to put in and take out the internal modules.

The lifting and lowering of the movable cover 9 drives the electrostatic dust removal brush rollers 17 to roll and clean the dust filter screen 10. The electrostatic dust removal brush rollers 17 are rotatably connected to the connecting rods 16. When they roll to clean, the friction between them and the dust filter screen 10 is reduced, avoiding wear on the screen surface. At the same time, the rolling contact improves the uniformity of dust removal and solves the problem of incomplete cleaning of certain areas by the fixed brush roller.

[0041] Working principle:

[0042] When using this utility model,

[0043] Intelligent control process: The sensing module 19 collects parameters such as pressure and temperature of the pressure vessel pipeline 5 through the connecting pipe 4 and transmits them to the control module 18 through the aviation connector; After analyzing the data, the control module 18 regulates the relevant components of the pressure vessel, such as the safety valve, through the execution module 20. In case of abnormality, the warning light 3 is triggered to alarm, and the data is displayed synchronously on the display screen 2.

[0044] Inspection and maintenance process: When inspection is required, the drive motor 11 drives the first gear 12 and the second gear 13 to rotate, which in turn drives the threaded rod 14 to rotate. The movable cover 9 moves up and down along the slide rod 15 to open the outer shell. After the faulty module is removed, a new module is replaced and reconnected through the aviation connector. During the lifting and lowering of the movable cover 9, the electrostatic dust removal brush roller 17 moves with the connecting rod 16 to clean the dust on the dust filter 10 and ensure that the heat dissipation vent 8 is unobstructed.
