Description

Technical Field

[0001] This utility model relates to the field of nitrogen generation technology, specifically to a nitrogen generation device with automatic flow rate adjustment. Background Technology

[0002] In industrial production, nitrogen is a commonly used protective gas, isolation gas, and carrier gas. However, traditional nitrogen generation equipment has some problems during use;

[0003] Traditional nitrogen generators consist of a compressor and a nitrogen separator. The compressor compresses air to a certain pressure, and then the nitrogen separator uses a molecular sieve to separate nitrogen. However, the required nitrogen flow rate varies depending on the operating environment; existing nitrogen generators lack an adjustment mechanism on the exhaust pipe, making it difficult to precisely control the flow rate as needed. This results in the inability to adjust the nitrogen flow rate according to actual requirements during use, thus affecting performance. To address these issues, we propose a nitrogen generator with automatically adjustable flow rate. Utility Model Content

[0004] The technical problem this invention aims to solve is that a fixed flow rate results in poor applicability. The invention provides a nitrogen generator with an automatically adjustable flow rate.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an automatically adjustable nitrogen generator, comprising a nitrogen generator body, wherein a compressor and a nitrogen separator are provided inside the nitrogen generator body, and a flow regulating mechanism is provided on the outer wall of the nitrogen generator body. The flow regulating mechanism includes a movable frame, and multiple exhaust pipes are evenly connected to one side wall of the movable frame. A flow regulating valve is provided on the side of the exhaust pipe near the movable frame, and a flow detector is provided on the exhaust pipe on the other side of the flow regulating valve. The flow regulating valve and the flow detector are electrically connected. A gas guide pipe is connected to the top surface of the movable frame. Multiple diversion pipes connected to the nitrogen separator are embedded in the outer wall of the nitrogen generator body. A gas guide hose is provided between the diversion pipe and the gas guide pipe. A pressure sensor is embedded in the compressor, and an adjustment knob electrically connected to the pressure sensor is provided on the outer wall of the nitrogen generator body.

[0006] As an improvement, a filter is provided at the top of the inner wall on one side of the nitrogen generator body. The inlet end of the filter is provided with an air inlet pipe extending to the outside of the nitrogen generator body, and the outlet end of the filter is provided with an air delivery pipe connected to the compressor. This allows the air to be purified before use, improving the quality of nitrogen production and avoiding blockages that could affect the precise adjustment of the flow rate.

[0007] As an improvement, an L-shaped support frame is fixedly provided on the outer wall of the nitrogen generator body, and the flow regulation mechanism is located inside the support frame. The support frame is provided with a plurality of fixing holes that cooperate with the exhaust pipe, so as to facilitate the limiting of the flow regulation mechanism.

[0008] As an improvement, a set of sliding grooves are symmetrically provided on the outer wall of the nitrogen generator body, and a sliding plate is slidably provided in the sliding grooves. A retaining plate is fixedly provided on the bottom surface of the sliding plate, and the L-shaped support frame is provided with a retaining groove to cooperate with the retaining plate, which facilitates the quick installation of the flow adjustment mechanism and improves efficiency.

[0009] As an improvement, a threaded screw is rotatably provided in the slide groove and threadedly connected to the sliding plate. The threaded screw is located in any slide groove, and a motor that drives the threaded screw is provided in the slide groove. A through hole for cooperating with the air guide tube is provided through the sliding plate. Sealing rings are provided in both the through hole and the fixing hole. The electric control flow regulation mechanism can be quickly installed and disassembled, making it convenient to use.

[0010] As an improvement, the bottom surface of the sliding plate is evenly provided with multiple return springs, and the other end of the return spring is connected to a set of return fastening plates. The return fastening plates extend to be set close to the top surface of the moving frame, which can limit and fix the moving frame of the flow regulating mechanism, thereby improving the stability of the operation.

[0011] As an improvement, the card plate is made of transparent material, the movable frame is equipped with a controller that works with the flow regulating valve and the flow detector, and the movable frame is equipped with a display screen for easy observation and precise adjustment by the operator.

[0012] As an improvement, multiple exhaust pipes are evenly arranged, and the flow regulating valves and flow detectors between the multiple exhaust pipes are independent of each other. The controller independently controls the flow regulating valve and flow detector on each exhaust pipe, realizing the independence between exhaust pipes. This allows the nitrogen emission flow rate on each exhaust pipe to be adjusted as needed, meeting different requirements and making it more practical.

[0013] The advantages of this utility model compared with the prior art are: the automatic adjustment of nitrogen feeding is achieved by setting a detachable flow adjustment mechanism, making it suitable for different use environments, thereby improving the practicality of the device;

[0014] By installing a pressure sensor on the compressor and adjusting the knob, the pressure can be regulated, thereby regulating the nitrogen production flow rate and automating the flow control. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1-6 As shown, an automatic flow rate regulating nitrogen generator includes a nitrogen generator body 1, a compressor 2 and a nitrogen separator 3 are provided inside the nitrogen generator body 1, a filter 14 is provided at the top of the inner wall of one side of the nitrogen generator body 1, an air inlet pipe 15 extending to the outside of the nitrogen generator body 1 is provided at the inlet end of the filter 14, and a gas delivery pipe 16 connected to the compressor 2 is provided at the outlet end of the filter 14.

[0024] With the above structure, when the nitrogen generator body 1 is in use, the compressor 2 is turned on to compress the outside air after it is filtered through the filter 14. The compressed air enters the nitrogen separator 3, and the molecular sieve in the nitrogen separator 3 filters out the nitrogen, thus realizing the preparation of nitrogen.

[0025] The nitrogen generator body 1 has a flow regulating mechanism 4 on its outer wall. The flow regulating mechanism 4 includes a movable frame 5. Multiple exhaust pipes 6 are evenly connected to one side wall of the movable frame 5. A gas guide pipe 9 is connected to the top surface of the movable frame 5. Multiple diversion pipes 10 are embedded in the outer wall of the nitrogen generator body 1 and communicate with the nitrogen separator 3. A gas guide hose 11 is provided between the diversion pipe 10 and the gas guide pipe 9. An L-shaped support frame 17 is fixedly provided on the outer wall of the nitrogen generator body 1. The flow regulating mechanism 4 is located inside the support frame. Multiple fixing holes 18 that cooperate with the exhaust pipes 6 are evenly connected on the support frame. A set of sliding grooves 19 are symmetrically provided on the outer wall of the nitrogen generator body 1. A sliding plate 2 is slidably installed in the sliding grooves 19. 0. A retaining plate 21 is fixedly provided on the bottom surface of the sliding plate 20. The L-shaped support frame 17 is provided with a retaining groove 22 that matches the retaining plate 21. A threaded screw 23 that is threadedly connected to the sliding plate 20 is rotatably provided in the sliding groove 19. The threaded screw 23 is located in any sliding groove 19. A motor that drives the threaded screw 23 is provided in the sliding groove 19. A through hole 24 that matches the air guide pipe 9 is provided through the sliding plate 20. Sealing rings are provided in both the through hole 24 and the fixing hole 18. A plurality of return springs 25 are evenly provided on the bottom surface of the sliding plate 20. A set of return fastening plates 26 are connected to the other end of the return springs 25. The return fastening plates 26 extend to be set close to the top surface of the moving frame 5. The retaining plate 21 is made of transparent material.

[0026] With the above structure, before use, the movable frame 5 is placed inside the L-shaped support frame 17, so that the exhaust pipe 6 on the movable frame 5 extends through the fixing hole 18 to the outside of the L-shaped support frame 17. Then, the threaded screw 23 is driven to rotate, so that the sliding plate 20 slides down with the cooperation of the sliding groove 19 until the sliding plate 20 is close to the top surface of the L-shaped support frame 17. At this time, the clamping plate 21 enters the clamping groove 22, and the air guide pipe 9 extends through the through hole 24 to the top of the sliding plate 20. The sealing ring improves the tightness of the air guide pipe 9 and the exhaust pipe 6. At the same time, the reset fastening plate 26 is close to the top surface of the movable frame 5 under the action of the reset spring 25, completing the fastening installation operation of the movable frame 5. The two ends of the air guide hose 11 are connected to the diverter pipe 10 and the air guide pipe 9 respectively.

[0027] The exhaust pipe 6 is provided with a flow regulating valve 7 on the side near the moving frame 5. The exhaust pipe 6 is provided with a flow detector 8 located on the other side of the flow regulating valve 7. The flow regulating valve 7 and the flow detector 8 are electrically connected. The moving frame 5 is provided with a controller 27 that works with the flow regulating valve 7 and the flow detector 8. The moving frame 5 is provided with a display 28. Multiple exhaust pipes 6 are evenly arranged. The flow regulating valves 7 and flow detectors 8 of the multiple exhaust pipes 6 are independent of each other. The controller 27 independently controls the flow regulating valve 7 and flow detector 8 on each exhaust pipe 6. The compressor 2 is embedded with a pressure sensor 12. The outer wall of the nitrogen generator body 1 is provided with an adjustment knob 13 that is electrically connected to the pressure sensor 12.

[0028] With the above structure, the prepared nitrogen gas enters the gas delivery hose 11 through the splitter pipe 10. The gas delivery hose 11 then transfers the nitrogen gas to the moving frame 5 through the gas delivery pipe 9. The nitrogen gas in the moving frame 5 is then extracted for use through each individual exhaust pipe 6 with the assistance of the flow regulating valve 7. The flow regulating valve 7 is adjusted according to usage requirements with the flow detector 8 to ensure that the nitrogen flow rate meets the usage requirements. During use, the compression force of the compressor 2 can be adjusted by adjusting the knob 13 in conjunction with the pressure sensor 12, thereby achieving flow rate regulation (specifically, when the intake pressure of the compressor 2 increases, the compression ratio of the compressor 2 increases, thereby increasing the nitrogen flow rate. Conversely, when the intake pressure of the compressor 2 decreases, the compression ratio of the compressor 2 decreases, thereby decreasing the nitrogen flow rate. Similarly, when the exhaust pressure of the compressor 2 increases, the compression ratio of the compressor 2 increases, thereby increasing the nitrogen flow rate. Conversely, when the exhaust pressure of the compressor 2 decreases, the compression ratio of the compressor 2 decreases, thereby decreasing the nitrogen flow rate).

[0029] In the specific implementation of this utility model, firstly, before use, the movable frame 5 is placed inside the L-shaped support frame 17, so that the exhaust pipe 6 on the movable frame 5 extends through the fixing hole 18 to the outside of the L-shaped support frame 17. Then, the threaded screw 23 is driven to rotate, so that the sliding plate 20 slides downward with the cooperation of the sliding groove 19 until the sliding plate 20 is in close contact with the top surface of the L-shaped support frame 17. At this time, the clamping plate 21 enters the clamping groove 22, and the air guide pipe 9 extends through the through hole 24 to the top of the sliding plate 20. The sealing ring improves the tightness between the air guide pipe 9 and the exhaust pipe 6. At the same time, the reset fastening plate 26 is in close contact with the top surface of the movable frame 5 under the action of the reset spring 25, completing the fastening installation operation of the movable frame 5. The two ends of the air guide hose 11 are connected to the diverter pipe 10 and the air guide pipe 9 respectively.

[0030] When the nitrogen generator body 1 is in use, the compressor 2 is turned on to compress outside air after it is filtered through the filter 14. During use, the compression force of the compressor 2 is adjusted by the adjustment knob 13 in conjunction with the pressure sensor 12 to regulate the flow rate. The compressed air enters the nitrogen separator 3, where the molecular sieve filters out the nitrogen. The prepared nitrogen enters the gas delivery hose 11 through the split pipe 10. The gas delivery hose 11 transfers the nitrogen to the moving frame 5 through the gas delivery pipe 9. The nitrogen in the moving frame 5 is taken out for use through each individual exhaust pipe 6 with the help of the flow regulating valve 7. The flow regulating valve 7 is adjusted according to the usage requirements in conjunction with the flow detector 8 to make the nitrogen flow rate meet the usage requirements.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
