Description
Technical Field

[0002] Existing air source boxes have certain limitations in industrial applications and related fields. The functions of common air source boxes on the market are relatively simple, and they often only focus on one aspect of the function, such as air source filtration or air source distribution. In actual production and usage scenarios, the demand for compressed air is often diverse. For example, in some specific industrial production processes, not only is room temperature compressed air required to drive conventional equipment or perform general operating tasks, but low temperature compressed air may also be required to meet special process requirements, such as certain temperature-sensitive material processing processes, or in some links that require rapid cooling. However, due to the limitations of its functions, the existing air source box design cannot simultaneously achieve the output of low-temperature and room temperature compressed air. This means that in actual applications, users have to use additional equipment or complex systems to obtain low-temperature and room temperature compressed air respectively, which not only increases the equipment cost and space occupancy, but also makes the entire air supply system more complicated, and the difficulty of operation and maintenance also increases accordingly, seriously affecting work efficiency and economic benefits.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0019] In this embodiment, Figures 1 to 3 As shown, a dual-temperature controlled air source distribution box for a temperature field measurement system includes a box body 1; a water drop separator 2 is fixed in the box body 1, the output end of the water drop separator 2 is connected to a filter pressure reducing valve 3, the output end of the filter pressure reducing valve 3 is connected to a flow valve 4, the first output end of the flow valve 4 discharges normal temperature air to the outside, the second output end of the flow valve 4 is connected to a vortex tube 6, the first output end of the vortex tube 6 discharges cold air to the outside, and the second output end of the vortex tube 6 discharges hot air to the outside.
[0020] In this embodiment, the box body 1 is made of stainless steel to avoid the possibility of rust caused by filtering and draining water. By filtering the compressed air to make it clean and dry before delivering it to the equipment, the service life of the equipment is prevented from being reduced due to air source quality problems. The low-temperature air obtains a cooling effect through the vortex tube 6, and the vortex tube 6 has no electronic components or control components, which greatly reduces the damage rate and maintenance cost of the equipment.
[0021] The water droplet separator 2 is a device used to separate liquid water droplets from gas. Its basic principle is to utilize inertia, centrifugal force, gravity, or a combination of these forces. When gas containing water droplets enters the water droplet separator, the airflow is redirected or rotated, preventing the water droplets from moving with the airflow due to their greater inertia, thereby achieving separation of the water droplets from the gas.
[0022] The filter pressure reducing valve 3 is a combined fluid control device with two main functions: filtering and pressure reducing.
[0023] Filtration: It removes impurities such as particles, rust, and dust from fluids (usually gas or liquid). This filtration works through internal filter elements, such as screens or filter cartridges. As the fluid passes through these filter elements, impurities are trapped on one side of the filter cartridge, while clean fluid passes through and continues to flow through the system. The filter in the filter-type pressure reducing valve intercepts impurities, preventing them from entering downstream equipment, thereby protecting the equipment from wear and clogging.
[0024] Pressure reducing function: It reduces the input fluid pressure to a set, stable output pressure. This is achieved through an internal pressure reducing mechanism. This mechanism typically consists of an adjustable valve and a pressure sensing element. When the input pressure exceeds the set output pressure, the valve automatically adjusts its opening, bypassing or throttling some of the fluid, thereby reducing pressure. A filter-type pressure reducing valve can reduce the source pressure to the required pressure range for the equipment and maintain a certain degree of stability in the output pressure.
[0025] A flow valve 4 is a valve used to control the flow of a fluid (liquid or gas). Its basic operating principle is to adjust the flow rate by changing the valve's flow cross-sectional area. When the valve opening increases, the flow cross-sectional area increases, and the flow rate increases. Conversely, when the valve opening decreases, the flow cross-sectional area decreases, and the flow rate decreases.
[0026] A vortex tube is a device that separates compressed gas into hot and cold streams through the vortex effect. Its principle is based on energy separation. When high-pressure gas (usually compressed air) enters the vortex tube's inlet at a tangential direction, the gas forms a high-speed rotating vortex within the tube. Due to the combined effects of the motion characteristics of the gas molecules and factors such as centrifugal force and friction during the rotation process, the gas produces energy redistribution.
[0027] Gas molecules near the central axis of the vortex tube move faster and have higher internal energy, becoming the hot air flow that is discharged from one end of the vortex tube (the hot end). Gas molecules near the tube wall move slower and have lower internal energy, becoming the cold air flow that is discharged from the other end of the vortex tube (the cold end). This allows the compressed gas's own energy to be used to separate the hot and cold air flows without external cooling or heating equipment.
[0028] In one or more embodiments of the present invention, a pressure relief valve 5 is connected between the flow valve 4 and the vortex tube 6 .
[0029] In this embodiment, during the operation of the flow valve 4 and the vortex tube 6, fluctuations in fluid flow or temperature changes may cause changes in pressure. The pressure relief valve can maintain the pressure within a relatively stable range. When the flow valve adjusts the flow so that the downstream pressure tends to increase, the pressure relief valve 5 can respond in a timely manner and balance the pressure by discharging a certain amount of fluid, ensuring that the vortex tube 6 operates in a stable pressure environment. This is conducive to the vortex tube 6 performing its normal functions, such as stably producing a hot and cold air flow separation effect.
[0030] In one or more embodiments of the present invention, the box body 1 is a rectangular parallelepiped structure as a whole, one side of which is an opening, and a sealing door 7 is hinged at the opening, and a cavity is formed in the box body 1.
[0031] In this embodiment, the water drop separator 2, the filter pressure reducing valve 3, the pressure relief valve 5, the vortex tube 6 and the flow valve 4 are integrated and installed through a sealed cavity.
[0032] In one or more embodiments of the present invention, an air inlet connector 8 is installed on the side of the box body 1, and the inner end of the air inlet connector 8 is connected to the input end of the water drop separator 2. The air inlet connector 8 is used to input 0.4-0.8 compressed air.
[0033] In this embodiment, the air inlet connector 8 provides an inlet channel for external air to enter the entire gas system. Connecting it to the water droplet separator 2 ensures that the incoming air first passes through the water droplet separator 2 for preliminary treatment to remove moisture, thereby preventing moisture from causing damage to subsequent equipment, such as corrosion and blockage.
[0034] In one or more embodiments of the present invention, a normal temperature air outlet connector 9 and a cold air air outlet connector 10 are also installed on the side of the box body 1. The inner end of the normal temperature air outlet connector 9 is connected to the first output end of the flow valve 4 through a first air pipe 11; the inner end of the cold air outlet connector 10 is connected to the first output end of the vortex tube 6 through a second air pipe 12.
[0035] In this embodiment, the normal temperature air outlet connector 9 and the cold air outlet connector 10 provide discharge channels for different output air flows.
[0036] The normal temperature gas outlet connector 9 is connected to the first output end of the flow valve 4 so that the normal temperature fluid regulated by the flow valve 4 can be discharged from the system, meeting the application scenarios that require normal temperature fluid.
[0037] The cold air outlet connector 10 is connected to the first output end of the vortex tube 6, and can discharge the cold air flow separated by the vortex tube 6, providing a dedicated output channel for occasions where cold air is needed, realizing the separate utilization of air flows at different temperatures, and improving the applicability and flexibility of the system.
[0038] In one or more embodiments of the present invention, an exhaust pipe is fixed to the second output end of the vortex tube 6 , and the other end of the exhaust pipe extends to the discharge port at the bottom of the box body 1 .
[0039] In this embodiment, the second output end of the vortex tube 6 typically discharges hot air or air no longer needed after energy separation. Providing an exhaust pipe extending to the discharge port at the bottom of the housing ensures that this airflow can be safely and orderly discharged from the system, preventing accumulation within the system that could cause pressure increases or affect the normal operation of other equipment. Furthermore, placing the discharge port at the bottom of the housing 1 also facilitates the natural upward diffusion of the hot air flow, minimizing its impact on the surrounding environment.
[0040] In one or more embodiments of the present invention, two fixing seats 13 are fixed to the upper side and the lower side of the box body 1 respectively.
[0041] In this embodiment, mounting bases 13 provide a mounting and securing location for the housing, ensuring the stability of the entire device during operation. Two mounting bases 13 are provided on the upper and lower sides, respectively, allowing the housing 1 to be securely fixed in place in various installation environments, preventing vibration, external forces, and other factors that may cause the housing 1 to shake or shift, thereby ensuring the normal operation of the internal components.
[0042] Working principle of this utility model:
[0043] After the compressed air is connected to the outside and the moisture and impurities in the air are filtered through the water droplet separator 2 and the filter pressure reducing valve 3, part of the air source is output to the equipment at room temperature through the flow valve 4, and the other part is divided into hot and cold air through the vortex tube 6. The hot air is directly discharged to the external space, and the cold air is output to the required equipment.
