Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerated dryer technology, and more specifically, to a gas storage tank for a refrigerated dryer. Background Technology
[0002] Air receivers are crucial auxiliary devices in compressed air systems, typically used in conjunction with refrigerated dryers. Their primary functions are storing compressed air, stabilizing system pressure, and providing initial cooling and moisture separation. Air receivers are generally installed between the air compressor and the refrigerated dryer. One of their core functions is to utilize the space within the tank to lower the temperature of the compressed air, causing most of the liquid water and oil to condense and be discharged, thus protecting the refrigerated dryer from efficiency degradation or damage due to handling excessively high-temperature air. This also reduces the burden on subsequent filters. However, existing air receivers have a significant drawback: the intake airflow has an excessively short residence time within the tank, and the flow path is not optimized, leading to a tendency for the air to directly short-circuit out of the outlet. This is essentially an "airflow short-circuit effect," severely reducing the processing efficiency and usability of the air receiver. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a gas storage tank for a refrigerated dryer, which has a simple structure and can effectively increase the residence time of the intake airflow in the tank, thereby improving the processing efficiency and use value of the gas storage tank.
[0004] This utility model provides an air storage tank for a refrigerated dryer, including a tank body and a guide pipe; the tank body is provided with an air inlet, an air outlet and a water outlet from top to bottom; the guide pipe is disposed in the tank body, with one end of the guide pipe facing the air inlet and the other end facing the inner wall of the tank body, for extending the airflow path; the air outlet is disposed facing the outer peripheral wall of the guide pipe.
[0005] Compared with the prior art, this application has the following advantages: During air intake, the water outlet is closed, and the airflow is injected into the tank through the air inlet and passes through the guide pipe. The guide pipe causes the airflow to contact the inner wall of the guide pipe, thereby extending the airflow path. This prevents the gas from flowing directly out of the air outlet after entering through the air inlet, avoiding the "airflow short-circuit effect" that leads to ineffective flow. It also allows the moisture in the airflow to accumulate into water droplets on the inner wall of the guide pipe and the inner wall of the tank. This allows the relatively dry and slightly lower pressure gas to flow out through the air outlet, and the water droplets will flow towards the water outlet. When needed, the water outlet can be opened to discharge the water, thereby improving the processing efficiency and use value of the gas storage tank.
[0006] In one possible implementation, the air inlet is located at the top of the tank; the air outlet is located on the side wall of the tank; the guide pipe has a cylindrical structure and is fixed to the inner wall of the tank and located directly below the air inlet, so that the guide pipe and the air inlet are coaxially arranged.
[0007] Compared with existing technologies, the above technical solution allows gas to enter directly from the top of the tank and flow downwards directly into the guide pipe. After the gas comes into contact with the inner wall of the tank, it will flow out from the outlet, further reducing the "airflow short-circuit effect".
[0008] In one possible implementation, the top of the tank has an upward-arched structure, and the upper end of the guide pipe is fixed to the top wall inside the tank, so that a first gap is formed between the air inlet and the upper end of the guide pipe, and a second gap is formed between the outer peripheral wall of the guide pipe and the inner peripheral wall of the tank.
[0009] Compared with existing technologies, the arched structure of the above-mentioned technical solution allows a portion of the gas to diffuse evenly in the radial direction after entering. The gas slows down in the first gap and then enters the guide pipe more smoothly, which helps stabilize the airflow. The structure is also simple. The second gap allows the gas to bounce back after hitting the inner wall of the tank. The relatively dry and slightly lower pressure gas will flow out from the outlet through the second gap. At this time, some gas will come into contact with the outer peripheral wall of the guide pipe and the inner peripheral wall of the tank again, further reducing the "airflow short-circuit effect".
[0010] In one possible implementation, the water outlet is located at the lower end of the tank.
[0011] Compared with existing technologies, the above technical solution enables residual water to be effectively discharged by gravity alone.
[0012] In one possible implementation, a pair of mounting plates are also included, with the two mounting plates respectively disposed on both sides of the water outlet at the lower end of the tank.
[0013] Compared with existing technologies, the above technical solution allows for convenient vertical installation of the tank using two mounting plates.
[0014] In one possible implementation, each mounting plate includes a vertical plate and a horizontal plate; the upper end of the vertical plate is fixed to the lower end of the tank, and one end of the horizontal plate is fixed to the lower end of the vertical plate, so that the vertical plate and the horizontal plate are perpendicularly connected, and the cross-section of the vertical plate and the horizontal plate is L-shaped; mounting holes are provided on the horizontal plate.
[0015] Compared with existing technologies, the above technical solution facilitates the vertical installation of the tank through the mounting holes.
[0016] In one possible implementation, a pair of reinforcing rings are also included, which are respectively fixed to the inner peripheral walls on both axial sides of the tank.
[0017] Compared with existing technologies, the above technical solution can increase rigidity, optimize stress distribution and suppress deformation, thereby improving the overall strength of the tank, adapting to long-term operation of high-pressure airflow, and extending service life.
[0018] In one possible implementation, it further includes an air inlet pipe, an air outlet pipe, and a water outlet pipe; the air inlet pipe is connected to an air inlet; the air outlet pipe is connected to an air outlet; and the water outlet pipe is connected to a water outlet.
[0019] Compared with existing technologies, the above technical solution enables air to be introduced through an air intake pipe, air to be discharged through an air outlet pipe, and water to be discharged through a water outlet pipe. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] As attached Figure 1 and attached Figure 2 As shown, this embodiment discloses an air storage tank for a refrigerated dryer, including a tank body 1 and a guide pipe 2; the tank body 1 is provided with an air inlet 11, an air outlet 12 and a water outlet 13 from top to bottom; the guide pipe 2 is disposed inside the tank body 1, with one end of the guide pipe 2 facing the air inlet 11 and the other end facing the inner wall of the tank body 1, for extending the airflow path; the air outlet 12 is disposed towards the outer peripheral wall of the guide pipe 2.
[0029] Specifically, in this embodiment, one end of the guide pipe 2 is aligned with the air inlet 11, and the other end is set towards the inner wall of the tank 1 to extend the airflow path. When air is inlet, the water outlet 13 is closed, and the airflow will enter the tank 1 through the guide pipe 2 from the air inlet 11. The guide pipe 2 will make the airflow contact the inner wall of the guide pipe 2, thereby extending the airflow path. This prevents the gas from flowing in from the air inlet 11 and then directly flowing out from the air outlet 12, avoiding the "airflow short-circuit effect" that leads to ineffective flow. It also allows the moisture in the airflow to accumulate into water droplets on the inner wall of the guide pipe 2 and the inner wall of the tank 1, so that the relatively dry and slightly low-pressure gas flows out from the air outlet 12. The water droplets will flow to the water outlet 13, and the water outlet 13 will be opened and discharged when needed, thereby improving the processing efficiency and use value of the gas storage tank.
[0030] As attached Figure 2 As shown, in some embodiments, the air inlet 11 is opened at the upper end of the tank body 1; the air outlet 12 is opened on the side wall of the tank body 1; the guide pipe 2 has a cylindrical structure and is fixed on the inner wall of the tank body 1 and located directly below the air inlet 11, so that the guide pipe 2 and the air inlet 11 are coaxially arranged.
[0031] Specifically, in this embodiment, the air inlet 11 is located in the middle of the upper end of the tank body 1, and the upper end of the guide pipe 2 is fixed to the top wall inside the tank body 1. The gas enters directly from the air inlet 11 at the upper end of the tank body 1 and flows downward directly into the guide pipe 2. After the gas comes into contact with the inner wall of the tank body 1, it flows out from the air outlet 12, further reducing the "airflow short-circuit effect".
[0032] As attached Figure 2 As shown, in some embodiments, the top of the tank 1 has an upward arched structure, and the upper end of the guide pipe 2 is fixed to the top wall inside the tank 1, so that a first gap 100 is formed between the air inlet 11 and the upper end of the guide pipe 2, and a second gap 101 is formed between the outer peripheral wall of the guide pipe 2 and the inner peripheral wall of the tank 1.
[0033] Specifically, in this embodiment, the left and right sides of the upper end of the guide pipe 2 are fixed to the top wall inside the tank 1. Since the top of the tank 1 has an upward arched structure, a first gap 100 is naturally formed between the middle area of the upper end of the guide pipe 2 and the air inlet 11. The arched structure allows some gas to diffuse radially and evenly along the top wall inside the tank 1 after entering. The gas will slow down in the first gap 100 and then enter the guide pipe 2 more smoothly, which helps to stabilize the airflow. The structure is simple. The diameter of the guide pipe 2 is smaller than the diameter of the tank 1, so that a second gap 101 is formed between the outer peripheral wall of the guide pipe 2 and the inner peripheral wall of the tank 1. The second gap 101 allows the gas to bounce back after hitting the inner wall of the tank 1. The relatively dry and slightly lower pressure gas will flow out from the air outlet 12 through the second gap 101. At this time, some gas will come into contact with the outer peripheral wall of the guide pipe 2 and the inner peripheral wall of the tank 1 again, further reducing the "airflow short-circuit effect".
[0034] As attached Figure 1 Or attached Figure 2 As shown, in some embodiments, the water outlet 13 is located at the lower end of the tank body 1. This allows residual water to be effectively discharged by gravity alone.
[0035] As attached Figure 1 As shown, in some embodiments, a pair of mounting plates 3 are also included, with the two mounting plates 3 respectively disposed on both sides of the lower end of the tank body 1 at the outlet hole 13. Each mounting plate 3 includes a vertical plate 31 and a horizontal plate 32; the upper end of the vertical plate 31 is fixed to the lower end of the tank body 1, and one end of the horizontal plate 32 is fixed to the lower end of the vertical plate 31, so that the vertical plate 31 and the horizontal plate 32 are perpendicularly connected, and the cross-sections of the vertical plate 31 and the horizontal plate 32 are L-shaped; the horizontal plate 32 is provided with mounting holes 33.
[0036] Specifically, in this embodiment, the mounting hole 33 is a screw hole, which facilitates the vertical installation of the tank 1 on the external support platform by using screws or bolts or other fasteners in the two mounting holes 33.
[0037] As attached Figure 2 As shown, in some embodiments, a pair of reinforcing rings 4 are also included, respectively fixed to the inner peripheral walls on both axial sides of the tank body 1. The two reinforcing rings 4 can increase the rigidity of both axial sides of the tank body 1, optimize stress distribution, and suppress radial deformation, thereby improving the overall strength of the tank body 1, adapting to long-term operation of high-pressure airflow, and extending its service life.
[0038] As attached Figure 1 Or attached Figure 2 As shown, in some embodiments, it also includes an air inlet pipe 111, an air outlet pipe 121, and a water outlet pipe 131; the air inlet pipe 111 is connected to the air inlet 11; the air outlet pipe 121 is connected to the air outlet 12; and the water outlet pipe 131 is connected to the water outlet 13.
[0039] Specifically, in this embodiment, one end of the air inlet pipe 111 is connected to the air inlet 11, and the other end is connected to the air outlet of an external air compressor; one end of the air outlet pipe 121 is connected to the air outlet 12, and the other end is connected to the air inlet of an external refrigerated dryer; one end of the water outlet pipe 131 is connected to the water outlet 13, and the other end is connected to an external drainage outlet; this allows the tank 1 to take in air through the air inlet pipe 111, take out air through the air outlet pipe 121, and discharge wastewater through the water outlet pipe 131.
[0040] In the description of the embodiments of this application, it should be noted that the terms "inner" and "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.
