Abstract
Description
Technical Field
[0001] This invention relates to the field of liquid gas conveying devices, and more specifically to a liquid gas conveying device that is easy to adjust. Background Technology
[0002] Liquid gas conveying devices are a type of equipment specifically designed to facilitate the directional transport of cryogenic liquid gases (such as liquid oxygen, liquid nitrogen, and liquid argon) from storage containers to end-use equipment. Their core function is to achieve efficient and safe fluid transfer while maintaining the cryogenic characteristics and stable state of the liquid gas. They are a key hub connecting the production, storage, and application of liquid gases, and their performance directly determines the continuity, safety, and precision of downstream industry production and application.
[0003] Traditional liquid gas conveying devices have several shortcomings in use. On the one hand, liquid gases may contain impurities, which, if not effectively filtered, can easily clog pipelines or damage downstream equipment, affecting the continuity of conveying. On the other hand, fluctuations in flow rate, temperature, and pressure during conveying can lead to instability in the liquid gas state, and even cause safety risks. Traditional devices lack real-time monitoring and adaptive adjustment capabilities, making it difficult to cope with complex operating conditions. In addition, the filter components of some traditional devices are prone to reduced filtration efficiency due to impurity accumulation, requiring frequent manual cleaning and increasing maintenance costs. Furthermore, liquid gas leaks are difficult to detect in a timely manner, which may lead to resource waste or safety accidents, requiring corresponding solutions. Summary of the Invention

A centrifugal force-driven variable resistance structure converts the flow rate into an electrical signal, which is then fed back to the PLC controller for precise flow rate monitoring and adjustment, ensuring a stable delivery rate. When the flow rate gradually decreases and reaches a set threshold, the motor starts and drives the cleaning rod to remove impurities accumulated on the filter plate surface, thus preventing filter clogging and eliminating the need for frequent manual maintenance. This improves filtration efficiency and device continuity. When the filter plate cleaning is complete and the flow rate increases and exceeds the set threshold, the filtration efficiency enhancement component automatically shuts off, better meeting practical usage requirements.

A pressure-driven variable resistance structure monitors pressure changes, and a PLC controller, in conjunction with a cryogenic precision regulating valve, compensates for pressure fluctuations, ensuring stable pressure in the outlet pipe and meeting the requirements of downstream equipment. This invention, through its leak alarm component, can promptly detect and alert to liquid gas leaks. The combination of an infrared gas sensor and an alarm light can quickly detect leaks and issue warnings, while simultaneously cutting off input to avoid safety accidents and resource waste.

[0023] The working principle of this invention is as follows: When using this easily adjustable liquid gas conveying device, the conveying and full-process adjustment of liquid gas are completed according to the following process; First, the device is started, and the external power supply powers all components. The PLC controller 13 enters standby mode. The operator opens the solenoid valve 24 on the inlet pipe 21 through the PLC controller 13. Liquid gas enters the housing 22 through the inlet pipe 21, passes through the filter plate 23 to filter out impurities, and then enters the first inlet pipe 25 and the second inlet pipe 26 in sequence. Finally, it is transported to the downstream equipment through the outlet pipe 27. During the transportation process, the flow rate detection component 3 monitors the flow rate in real time. The liquid gas pushes the guide plate 32 to drive the first rotating shaft 31 to rotate. The moving block 36 on the rotating block 33 slides along the guide rod 35 due to centrifugal force. Through the connecting block 311, it drives the first conductive ring 310 to move along the first variable resistance rod 39, changing the resistance. The PLC controller 13 receives the resistance signal and calculates the flow rate. If the flow rate is abnormal, the PLC controller 13 will detect the abnormal flow rate. The flow rate can be adjusted by the low-temperature precision regulating valve 28. The faster the flow rate, the greater the centrifugal force generated by the rotation of the first rotating shaft 31. The moving block 36 moves more towards the first spring 37, and the resistance gradually increases. Similarly, the lower the flow rate, the lower the resistance gradually decreases. The filtration efficiency improvement component 4 works synchronously. The PLC controller 13 starts the motor 41 according to the flow rate detection result (if the flow rate drops to a certain value, it is judged that the filter plate 23 may be blocked). The motor 41 drives the second rotating shaft 43 to rotate. Through the meshing of the first bevel gear 45 and the second bevel gear 46, the third rotating shaft 44 is driven to rotate. The cleaning rod 47 scrapes off the impurities on the surface of the filter plate 23 and restores the filtration efficiency. The impurities can be periodically discharged by removing the housing 22 later. In this way, the high efficiency of the conveying and the cleanliness of the conveyed liquid gas are guaranteed. Temperature control and adjustment component 5 is used to maintain temperature stability. Temperature sensor 56 detects the temperature of liquid gas in the first infusion pipe 25 and transmits the data to PLC controller 13. If the temperature is higher than the set value, PLC controls pressure reducing valve 53 to open. Liquid nitrogen enters spiral temperature regulating pipe 54 from liquid nitrogen storage tank 51 through first temperature regulating pipe 52. Through heat exchange, it cools the liquid gas in second infusion pipe 26. The liquid nitrogen tail gas after heat exchange is discharged through second temperature regulating pipe 55. After the temperature reaches the standard, pressure reducing valve 53 closes and liquid nitrogen supply stops. The adaptive pressure compensation component 6 is used to balance the delivery pressure. The liquid gas pressure in the outlet pipe 27 pushes the inclined bottom detection block 63 to move up and down, which drives the slide rod 65 and the second conductive ring 67 to slide along the second variable resistance rod 66, changing the resistance. The principle here is similar to that of the flow rate detection component 3 mentioned above. The PLC controller 13 judges the pressure based on the resistance signal. If the pressure is too low, it controls the low temperature precision regulating valve 28 to increase the opening and increase the flow rate to compensate for the pressure. If the pressure is too high, it reduces the opening to ensure that the pressure is stable and the delivery process is safe and efficient enough. The leakage alarm component 7 monitors safety throughout the process. The infrared gas sensor 71 detects the gas concentration in the cavity 11 in real time. If liquid gas leaks and the concentration exceeds the threshold, the sensor transmits a signal to the PLC controller 13. The PLC immediately controls the alarm light 72 to flash and can simultaneously close the solenoid valve 24 to cut off the input and prevent the leakage from expanding. Throughout the entire transportation process, the PLC controller 13 integrates the monitoring data of each component to achieve automatic adjustment of flow rate, temperature, and pressure, as well as dynamic improvement of filtration efficiency and timely alarm of leakage, ensuring stable, safe, and efficient liquid gas transportation.
