Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling cabinet technology, specifically a dual-module mixed gas filling cabinet that does not discharge residual gas. Background Technology
[0002] Mixed gases are widely used in industrial, medical, food, and scientific research fields, and their mixing accuracy and filling safety are crucial. Traditional mixed gas filling equipment relies heavily on manual operation, resulting in low mixing accuracy and poor stability. Furthermore, residual gas in the pipeline must be discharged after each mixing cycle, leading to gas waste, environmental pollution, and safety risks. Although existing technologies have attempted to improve this by incorporating automatic control and exhaust devices, they still generally suffer from low integration, lack of real-time closed-loop monitoring, and inability to recover and reuse residual gas. Therefore, there is an urgent need to develop a new filling system that integrates high-precision automatic mixing, real-time parameter monitoring, and residual gas recovery and reuse functions to improve efficiency and meet environmental protection and safety production requirements. Utility Model Content

The device includes an all-aluminum profile control cabinet frame; an automatic clean pipe gas distribution valve assembly is fixedly installed on the top side of the all-aluminum profile control cabinet frame; an integrated instrument panel is fixedly installed on the top front side of the all-aluminum profile control cabinet frame; an external high-definition touch screen box is bolted to the front side of the all-aluminum profile control cabinet frame; the all-aluminum profile control cabinet frame is equipped with a fully transparent acrylic cabinet door, a three-color buzzer alarm, a valve assembly fixing bracket, and an electrical box; the automatic clean pipe gas distribution valve assembly is equipped with dual-path independent pneumatic control valves, a safety valve, a filter, and a one-way valve; the integrated instrument panel is equipped with a high-precision pressure sensor and a high-precision mechanical pressure gauge; the external high-definition touch screen box is equipped with an external high-definition touch display screen, which transmits data in real time and executes corresponding actions through the dual-module self-control program and the high-precision pressure sensor.
[0005] Preferably, the high-precision pressure sensor on the integrated instrument panel acquires pressure data in real time and feeds it back to the external high-definition touch screen box. The dual-module automatic control program issues execution commands, and the equipped high-precision mechanical pressure gauge provides a more intuitive real-time view of the pipeline system pressure.

By releasing the residual pressure into the fixed gas storage container, when refilling, the automatic control program will first open the control valve of the gas storage container to equalize the pressure with the gas cylinder to be filled. The entire process does not require the release of residual gas pressure.
[0007] Preferably, the automatic control program installed in the external high-definition touch screen box connects all equipment and instruments of this device to the automatic control system. The dual-module automatic control program controls the dual independent pneumatic control valves on the clean pipe automatic gas distribution valve group to achieve automatic gas distribution without interference.

[0017] The dual-path independent pneumatic control valve in the clean pipeline automatic gas distribution valve group 2 opens or closes according to the gas distribution ratio set on the external high-definition touch screen box 4, and operates automatically according to the set ratio formula. During the process, the gas source pipeline is independent and equipped with pipeline depressurization recovery and reuse.

[0020] During use, the operator first checks whether the pressure, temperature, and other data on the display screen of the external high-definition touch screen box 4 are normal. If the raw material gas and all instruments are normal, the required gas mixing accuracy and content can be preset in the proportional formula setting function of the high-definition touch screen display screen. After completing the above steps, the automatic program will generate an automatic gas mixing program according to the formula, and execute the action of the dual independent pneumatic control valve in the clean pipeline automatic gas mixing valve group 2 according to the program command. During this process, the integrated instrument panel 3 monitors the temperature and pressure in real time. The gas source pipeline is independent and equipped with a pipeline pressure relief and recovery reuse device, so there is no need to release pressure. After the gas mixing is completed, the data is generated and saved, and an alarm signal is issued.
