Description

Technical Field

[0001] This utility model relates to the field of energy saving in industrial pneumatic systems, and more specifically, to a pneumatic device. Background Technology

[0002] In feed production, pneumatic systems play a crucial role in material transport, valve control, and equipment linkage. However, in northern winters or high-altitude regions, ambient temperatures often drop below -20°C, causing moisture in the compressed air to condense and freeze inside pneumatic components (such as solenoid valves, pneumatic triple units, or cylinders), triggering the following chain reaction:

[0003] 1. Sticking of moving parts: Low temperature increases the viscosity of the lubricant, which causes a sharp increase in the frictional resistance between the valve core and the seal, resulting in delayed action or even failure;

[0004] 2. Deterioration of sealing performance: The rubber material hardens and shrinks at low temperatures, leading to gas leakage and system pressure fluctuations;

[0005] 3. Soaring energy consumption: Frequent start-stop cycles and high-voltage compensation further exacerbate energy waste.

[0006] Traditional solutions such as electric blankets or whole-house heating have significant drawbacks:

[0007] The former is prone to damage to components due to localized overheating, while the latter has high energy consumption and poor temperature control accuracy. Utility Model Content

[0015] In an optional embodiment, the first temperature control module further includes a bracket, a first air guide plate, and a second air guide plate. The directional unit, the first air guide plate, and the second air guide plate are all mounted on the bracket. The first air guide plate and the second air guide plate are arranged at intervals in the height direction of the pneumatic triplet. The side of the first air guide plate and the second air guide plate closest to the pneumatic triplet are inclined towards the pneumatic triplet. The first air guide plate is used to guide the hot air blown out by the first heating fan to the top of the pneumatic triplet, and the second air guide plate is used to guide the hot air blown out by the first heating fan to the bottom of the pneumatic triplet.

[0016] In an optional embodiment, the steering unit includes a motor, a support base, and a positioning sleeve. The output shaft of the motor is rotatably mounted on the support base, and the positioning sleeve is fixed to the output shaft of the motor. The cross-sectional profile of the positioning sleeve is set to be non-circular.

[0024] In summary, the pneumatic equipment provided in this embodiment operates by an air compressor that delivers compressed high-pressure air to a pneumatic triplet.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] In existing technologies, during the operation of pneumatic systems, especially in low-temperature environments during winter, moisture in the air easily condenses and freezes, leading to reduced operational stability and shorter lifespan of pneumatic components. Conventional methods using overall factory heating are energy-intensive and costly. While some manufacturers employ enclosed heating methods, these suffer from poor temperature control accuracy and the possibility of localized overheating, affecting the performance of pneumatic components.

[0037] In view of this, the designers have provided a pneumatic device that can not only reduce the impact of water vapor on pneumatic components in winter environments, but also save costs.

[0038] Please refer to Figures 1-2This embodiment provides a pneumatic device, including an air compressor, a pneumatic triplet 200, a solenoid valve assembly 300, a first temperature control module 400, and a second temperature control module 500, wherein:

[0039] The air compressor is connected to the pneumatic triplet 200, the pneumatic triplet 200 is connected to the solenoid valve assembly 300, and the solenoid valve assembly 300 is used to connect to the cylinder assembly 600 to control the working state of the cylinder assembly 600.

[0040] The first temperature control module 400 corresponds to the pneumatic triplet 200 and is used to heat the pneumatic triplet 200; the second temperature control module 500 corresponds to the solenoid valve group 300 and is used to heat the solenoid valve group 300.

[0041] As described above, the pneumatic equipment provided in this embodiment operates as follows:

[0042] During operation, the air compressor delivers compressed high-pressure air to the pneumatic triplet 200. The triplet 200 filters impurities from the high-pressure air, which is then delivered to the solenoid valve assembly 300. The solenoid valve assembly 300 regulates the flow rate and direction of the high-pressure air, thereby adjusting the working state of the cylinder assembly 600. During this process, the first temperature control module 400 and the second temperature control module 500 can operate simultaneously. The first temperature control module 400 heats the pneumatic triplet 200, raising its temperature and preventing water vapor in the high-pressure air from condensing and freezing inside the triplet 200, thus extending its service life. Simultaneously, the second temperature control module 500 heats the solenoid valve assembly 300, raising its temperature and preventing water vapor inside from freezing, thus reducing the risk of wear and tear on the sealing rings, resulting in high sealing performance and a long service life.

[0043] It should be noted that controlling the cylinder assembly's movement by adjusting the compressed gas flow rate and direction through the solenoid valve group 300 is a well-known existing technology. No improvements have been made to its structure and principle in this embodiment. To avoid repetition and redundancy, detailed descriptions are not provided in this embodiment.

[0044] The following embodiments illustrate the details of the pneumatic device of this application by way of example.

[0045] Please combine Figure 1In this embodiment, optionally, the pneumatic equipment includes a frame 100 and an air compressor (not shown), a pneumatic triplet 200, a solenoid valve assembly 300, a first temperature control module 400, a second temperature control module 500, and a cylinder assembly 600, all mounted on the frame 100. The air compressor is connected to the pneumatic triplet 200, the pneumatic triplet 200 is connected to the solenoid valve assembly 300, and the solenoid valve assembly 300 is connected to the cylinder assembly 600. The solenoid valve assembly 300 can control the working state of the cylinder assembly 600, that is, control the extension and retraction stroke of the cylinder assembly 600. The first temperature control module 400 corresponds to the pneumatic triplet 200 and is used to heat the pneumatic triplet 200; the second temperature control module 500 corresponds to the solenoid valve assembly 300 and is used to heat the solenoid valve assembly 300.

[0046] In this embodiment, optionally, the air compressor is connected to the inlet of the pneumatic triplet 200 via a pipeline. The pneumatic triplet 200 has a first outlet and a second outlet. The first outlet is connected to a solenoid valve via a pipeline, and a removable collection bottle is installed at the second outlet. When the air compressor is working, it draws in outside air, pressurizes it, and then delivers it to the pneumatic triplet 200 via a pipeline. The high-pressure gas is filtered and separated inside the pneumatic triplet 200, and the oil and gas in the high-pressure gas are separated and enter the collection bottle from the second outlet. The purified high-pressure gas is discharged from the first outlet via a pipeline and can reach the solenoid valve group 300. The solenoid valve group 300 distributes the flow to realize the extension and retraction control of the cylinder assembly 600.

[0047] It should be understood that the structure of the pneumatic triplet 200 can refer to the existing technology. No improvements have been made to its structure and principle in this embodiment. In order to avoid repetition and redundancy, it will not be described in detail in this embodiment.

[0048] In some embodiments, the pneumatic triplet 200 may also be referred to as an air source triplet.

[0049] In addition, when the amount of oil collected in the collection bottle is large, the collection bottle can be disassembled to avoid excessive oil affecting the separation effect.

[0050] In this embodiment, the number of solenoid valve groups 300 can be designed as needed and adjusted according to control requirements. A single solenoid valve can be used independently or multiple solenoid valves can be used in combination. This embodiment does not impose any specific limitations.

[0051] Please combine Figure 1In this embodiment, optionally, the first temperature control module 400 includes an insulation sleeve 410, a first heating fan 420, a directional unit 430, a bracket 440, a first air guide plate 450, and a second air guide plate 460. The air inlet and outlet of the pneumatic triplet 200 are distributed on its top and bottom. Wrapping the insulation sleeve 410 around the pneumatic triplet 200 reduces the heat dissipation rate of the pneumatic triplet 200, and the insulation sleeve 410 is less likely to interfere with the air inlet and outlet, thus minimizing impact on air intake and exhaust functions. The insulation sleeve 410 can be made of insulation cotton, etc., and can be fixed to the outside of the pneumatic triplet 200 using clamps or straps to improve stability.

[0052] Optionally, the first heating fan 420 can be installed on one side of the pneumatic triplet 200. A PTC ceramic heater can be installed inside the first heating fan 420 to heat the air, and then blow the heated air towards the pneumatic triplet 200. Obviously, the first heating fan 420 can also use a heating wire to heat the air, but this embodiment does not exhaustively describe all possibilities. At the same time, the steering unit 430, the first air guide plate 450, and the second air guide plate 460 are all installed on the bracket 440. One end of the steering unit 430 is connected to the first heating fan 420, which is used to drive the first heating fan 420 to perform pitch movement relative to the pneumatic triplet 200 within a set angle. The first air guide plate 450 and the second air guide plate 460 are arranged at intervals along the height direction of the pneumatic triplet 200. The height of the first air guide plate 450 is higher than the top height of the pneumatic triplet 200, and the height of the second air guide plate 460 is lower than the bottom height of the pneumatic triplet 200. The sides of both the first air guide plate 450 and the second air guide plate 460 closest to the pneumatic triplet 200 are inclined towards the pneumatic triplet 200. The first air guide plate 450 is used to guide the hot air blown by the first heating fan 420 to the top of the pneumatic triplet 200, and the second air guide plate 460 is used to guide the hot air blown by the first heating fan 420 to the bottom of the pneumatic triplet 200.

[0053] This design allows the directional unit 430 to adjust the airflow direction of the first heating fan 420 as needed, ensuring that hot air is better directed towards the pneumatic triplet 200. Furthermore, due to the design of the first and second air guide plates 450, when hot air blows towards the first air guide plate 450, it is directed downwards towards the top of the pneumatic triplet 200, heating the top area. Simultaneously, the heat from the heated top area is transferred to the middle section. Similarly, when hot air blows towards the second air guide plate 460, it is directed downwards towards the bottom of the pneumatic triplet 200, heating the bottom area. The overall temperature of the pneumatic triplet 200 can be controlled within a reasonable range, preventing internal moisture from freezing. Meanwhile, since the pneumatic triplet 200 is surrounded by an insulation sleeve 410, it has a good insulation effect, the temperature is not easily lost, and it can be maintained at the set temperature, thus reducing energy consumption.

[0054] Obviously, the surface temperature of the pneumatic triplet 200 can be obtained by setting a temperature sensor, thereby guiding the working state of the first temperature control module 400. That is, when the obtained temperature is low, the temperature of the hot air blown out by the first heating fan 420 can be increased; when the temperature is high, the temperature of the hot air blown out by the first heating fan 420 can be decreased or the air speed can be reduced, etc.

[0055] Please combine Figure 1 and Figure 2 Optionally, the directional unit 430 includes a motor 431, a support base 432, and a positioning sleeve 433. The output shaft of the motor 431 is rotatably mounted on the support base 432 via bearings. The positioning sleeve 433 is fixed to the output shaft of the motor 431, and the positioning sleeve 433 and the output shaft can be connected via splines to ensure that the positioning sleeve 433 does not rotate relative to the rotating shaft. The cross-sectional profile of the positioning sleeve 433 is set to be non-circular; for example, the cross-sectional profile of the positioning sleeve 433 can be rectangular. A buckle 530 is provided on the housing of the first heating fan 420. The buckle 530 engages with the positioning sleeve 433, and the buckle 530 and the positioning sleeve 433 are fixed relative to each other in the circumferential direction of the positioning sleeve 433. The buckle 530 can be set as a spring clip, which uses a clamping method to fix the first heating fan 420 on the positioning sleeve 433, making operation convenient and easy to disassemble and maintain.

[0056] In this embodiment, optionally, the second temperature control module 500 includes a second heating fan 510 and an air guide duct 520. The air guide duct 520 has a gradient air guide channel. The constricted end of the gradient air guide channel is close to the solenoid valve group, and the flared end of the gradient air guide channel is close to the air outlet of the second heating fan 510. The second heating fan 510 is used to deliver hot air to the air guide duct 520, and then deliver the hot air to the solenoid valve group 300 through the air guide duct 520.

[0057] It should be understood that the air guide duct 520 can be a conical cylinder, with the inner diameter of its cross-section gradually increasing from the constricted end to the flared end. Furthermore, the air guide duct 520 can be fixed in place using a frame. After fixing, the central axis of the air guide duct 520 forms an angle of 15°-30° with the horizontal plane, and the height of the constricted end is lower than the height of the flared end. In this way, the air guide duct 520 blows hot air obliquely downwards towards the solenoid valve assembly 300, increasing the heating area of ​​the solenoid valve assembly 300. Simultaneously, the hot air is guided by the air guide duct 520, concentrating the heat and covering the core area of ​​the solenoid valve assembly 300. The temperature difference of the solenoid valve assembly 300 itself is ≤±2℃, avoiding ineffective heat diffusion and achieving energy savings of over 30% compared to traditional heating methods.

[0058] In addition, the surface temperature of the solenoid valve assembly 300 can be obtained by setting a temperature sensor, thereby guiding the working status of the second temperature control module 500 and facilitating precise temperature control.

[0059] In this embodiment, optionally, the cylinder assembly 600 can be used to clamp goods, etc. The extension and retraction of the cylinder assembly 600 can be controlled by the solenoid valve group 300, which has a high degree of automation and flexible control.

[0060] The pneumatic device provided in this embodiment, through the combined use of the first temperature control module 400 and the second temperature control module 500, can respectively heat components such as the pneumatic triplet 200 and the solenoid valve assembly 300 at specific points, providing a stable heat source. This keeps the temperature of the pneumatic triplet 200 and the solenoid valve assembly 300 within a set range, preventing internal moisture from freezing due to excessively low temperatures. The pneumatic triplet 200 and the solenoid valve assembly 300 operate stably, are not easily damaged, and have a long service life. Simultaneously, the two temperature control modules are operated independently without interference, saving energy and reducing costs.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
