Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hydrogen compressor technology, and in particular relates to a hydrogen compressor gas circulation device. Background Technology
[0002] A hydrogen compressor circulation pipe is typically a closed piping system, including an intake pipe, an exhaust pipe, and connecting pipes. The intake pipe delivers low-pressure hydrogen to the compressor for compression, while the exhaust pipe delivers the compressed hydrogen to where it is needed or recirculates it back to the front end of the compressor.
[0003] To cool the gas in the circulation pipe, a cooling fan is usually installed on one side of the pipe. Although the cooling fan achieves the purpose of cooling, its heat dissipation effect is not good, and the air cooling loss is relatively large. In order to improve the cooling effect of the circulation pipe, we propose a hydrogen compressor gas circulation device to solve the shortcomings of the existing technology. Utility Model Content
[0004] The purpose of this invention is to provide a gas circulation device for a hydrogen compressor, which improves the cooling effect of the circulation pipe and reduces the pipe body temperature, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A gas circulation device for a hydrogen compressor includes a circulation pipe body, which is connected between a pump body and a compressor. A cooling pipe is fixedly sleeved and tightly fitted onto the surface of the circulation pipe body. The cooling pipe is spiral-shaped, with one end connected to a coolant tank and the other end connected to a circulation pump. The coolant tank and the circulation pump are connected. A concave seat is fixedly connected to the top of the pump body through a support frame. A stepper motor is slidably mounted on the inner surface of the concave seat. A fan blade is fixedly connected to the output shaft of the stepper motor. The stepper motor is connected through a movable structure and moves by the drive of the movable structure.
[0006] Preferably, the movable structure includes a connecting plate fixedly connected to one side of the concave seat, and an electric telescopic rod fixedly connected to the front of the connecting plate. A movable plate is fixedly connected to the telescopic end of the electric telescopic rod. Support plates are fixedly connected to the front and back of the concave seat, and a guide rod is fixedly connected to the opposite side of the support plate. The inner surface of the movable plate is slidably connected to the outer surface of the guide rod.
[0007] Preferably, one side of the moving plate is fixedly connected to the stepper motor, and there is a gap between one end face of the fan blade and the outer surface of the cooling pipe.
[0008] Preferably, a through groove is provided on one side of the concave seat, and the outer surface of the movable plate is slidably connected to the inner surface of the through groove.
[0009] Preferably, one side of the concave seat is an open structure.
[0010] Preferably, the coolant tank is detachably connected to the cooling pipe and the circulating pump, and the top of the coolant tank is connected to a feed pipe.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model uses a circulating pump to draw coolant from the coolant tank into the interior of the cooling pipe. The spiral design of the cooling pipe lowers the temperature of the circulating pipe body due to the coolant, which in turn lowers the temperature of the gas inside the circulating pipe. At the same time, a moving structure drives a stepper motor to move, and the stepper motor drives the fan blades to rotate, blowing away the heat. By setting up the above structure, the cooling effect of the circulating pipe is improved and the pipe body temperature is reduced.
[0013] 2. This utility model uses an electric telescopic rod to drive the moving plate to move, so that the moving plate slides on the inner surface of the through groove, and the inner surface of the moving plate slides on the outer surface of the guide rod, thereby driving the stepper motor to move and increasing the blowing range.
[0014] 3. This utility model features an open structure on one side of the concave seat, allowing heat to be blown away and thus enabling timely heat dissipation;
[0015] 4. This utility model provides a material pipe connected to the top of the coolant tank, which facilitates the injection of coolant into the tank. Attached Figure Description

[0023] In the following description, embodiments of the hydrogen compressor gas circulation device of the present invention will be described with reference to the accompanying drawings. Example 1
[0024] Figure 1-4 This invention illustrates a hydrogen compressor gas circulation device according to an embodiment of the present invention. It includes a circulation pipe 3, which connects a pump body 1 and a compressor 2. A cooling pipe 4 is fixedly sleeved and tightly fitted to the surface of the circulation pipe 3. The cooling pipe 4 is spiral-shaped, with one end connected to a coolant tank 5 and the other end connected to a circulation pump 6. The coolant tank 5 and the circulation pump 6 are connected. A concave seat 7 is fixedly connected to the top of the pump body 1 via a support frame. A stepper motor 8 is slidably mounted on the inner surface of the concave seat 7. A fan blade 9 is fixedly connected to the output shaft of the stepper motor 8. The stepper motor 8 is connected via a movable structure and moves by the drive of the movable structure. The movable structure includes a connecting plate fixedly connected to one side of the concave seat 7, and an electric telescopic rod 10 fixedly connected to the front of the connecting plate. A moving plate 11 is fixedly connected to the telescopic end of the electric telescopic rod 10. Support plates are fixedly connected to the front and back of the concave seat 7, and a guide rod 12 is fixedly connected to the opposite side of the support plate. The inner surface of the moving plate 11 is connected to the guide rod. The outer surface of the guide rod 12 is slidably connected, and one side of the moving plate 11 is fixedly connected to the stepper motor 8. There is a gap between one end face of the fan blade 9 and the outer surface of the cooling pipe 4. A through groove 13 is provided on one side of the concave seat 7. The outer surface of the moving plate 11 is slidably connected to the inner surface of the through groove 13. The moving plate 11 is moved by the electric telescopic rod 10, so that the moving plate 11 slides on the inner surface of the through groove 13 and is slidably connected to the outer surface of the guide rod 12 through the inner surface of the moving plate 11, thereby driving the stepper motor 8 to move and increase the air blowing range. The coolant in the coolant tank 5 is drawn into the interior of the cooling pipe 4 by the circulation pump 6. Through the spiral design of the cooling pipe 4, the coolant in the cooling pipe 4 reduces the temperature of the circulation pipe 3, thereby reducing the temperature of the gas in the circulation pipe 3. At the same time, the moving structure drives the stepper motor 8 to move, and the stepper motor 8 drives the fan blade 9 to rotate, blowing away the heat. By setting the above structure, the cooling effect of the circulation pipe is improved and the pipe temperature is reduced. Example 2
[0025] Figure 1-4This invention illustrates a hydrogen compressor gas circulation device according to an embodiment of the present invention, comprising a circulation pipe 3 connected between a pump body 1 and a compressor 2. A cooling pipe 4 is fixedly sleeved and tightly fitted onto the surface of the circulation pipe 3. The cooling pipe 4 is spiral-shaped, with one end connected to a coolant tank 5 and the other end connected to a circulation pump 6. The coolant tank 5 and the circulation pump 6 are connected and detachably connected. A feed pipe is connected to the top of the coolant tank 5, facilitating the injection of coolant into the coolant tank 5. A concave seat 7 is fixedly connected to the top of the pump body 1 via a support frame. One side of the concave seat 7 is open, allowing heat to be blown away and thus timely heat dissipation. A stepper motor 8 is slidably mounted on the inner surface of the concave seat 7. A fan blade 9 is fixedly connected to the output shaft of the stepper motor 8. The stepper motor 8 is connected via a movable structure and moves by the drive of the movable structure.
[0026] Working principle: When this utility model is used, the coolant in the coolant tank 5 is drawn into the cooling pipe 4 by the circulating pump 6. The spiral design of the cooling pipe 4 makes the coolant in the cooling pipe 4 lower the temperature of the circulating pipe 3, thereby lowering the temperature of the gas in the circulating pipe 3. At the same time, the electric telescopic rod 10 drives the moving plate 11 to move, so that the moving plate 11 slides on the inner surface of the through groove 13 and is slidably connected to the outer surface of the guide rod 12 through the inner surface of the moving plate 11, thereby driving the stepper motor 8 to move, increasing the air blowing range. The stepper motor 8 drives the fan blade 9 to rotate, blowing away the heat, thereby improving the cooling effect of the circulating pipe and reducing the pipe temperature.
