Description

Technical Field

[0002] Compressed air is the most common medium in factories and has a wide range of uses. It is mainly divided into instrument air source, dust removal air source and miscellaneous air source. At present, in order to use equipment that requires compressed air (such as dust collector silo pump, etc.), a higher-pressure air compressor is used to transport compressed air to the equipment for working use. This is a way to use compressed air. However, since air compressors are in operation all year round, low-pressure gas is often needed during use. In this case, high-pressure air is used to directly replace low-pressure air, resulting in energy loss. Secondly, there is also the use of multiple air compressors with different pressures. Although this method can reasonably use compressed air, it will increase the production cost of the factory. Utility Model Content

The high-pressure air compressor 1 and the combined dryer 2 are connected by an air pipe, and pipeline I and pipeline II are both three-way pipelines. The high-pressure gas storage tank 5, the working device 9, the low-pressure gas storage tank 12 and the combined dryer 2, the high-pressure gas storage tank 5, and the low-pressure gas storage tank 12 are arranged in an integrated manner through pipeline I and pipeline II respectively. Pipeline I includes a pipe body I3 connected to the combined dryer 2, the high-pressure gas storage tank 5, and the low-pressure gas storage tank 12 respectively. Two gate valves I4 are arranged at the ends connecting the high-pressure gas storage tank 5 and the low-pressure gas storage tank 12, and a booster valve 10 is arranged on the end of the pipe body I3 connecting the low-pressure gas storage tank 12. The pipeline II includes a pipe body II11 connected to the high-pressure gas storage tank 5, a working equipment 9, and a low-pressure gas storage tank 12 respectively, a gate valve II7 and a check valve 6 are arranged in sequence at the end of the pipe body II11 connecting the high-pressure gas storage tank 5, and a gate valve II7, a check valve 6 and a pressure reducing valve 13 are arranged in sequence at the end of the pipe body II11 connecting the low-pressure gas storage tank 12. The diameter of the end of the pipe body I3 connecting the low-pressure gas storage tank 12 is larger than the diameter of the end of the pipe body I3 connecting the high-pressure gas storage tank 5, and the diameter of the end of the pipe body II11 connecting the low-pressure gas storage tank 12 is larger than the diameter of the end of the pipe body II11 connecting the high-pressure gas storage tank 5, wherein the change of the pipe diameter is changed by connecting the large and small heads.

[0018] Pressure gauges 8 are provided on both pipeline I and pipeline II, and the two pressure gauges 8 are respectively located at the end of the pipe body II 11 connected to the high-pressure gas storage tank 5 and the end of the pipe body I 3 connected to the low-pressure gas storage tank 12. The pressure gauge 8 can monitor the pipeline pressure in real time, and the pressure data used by the working equipment 9 is clearer.

[0019] Working principle:

[0020] When the working equipment 9 needs to use high-pressure air, the gate valve I4 on the low-pressure air storage tank 12 connected to the pipe body I3 is closed, and the gate valve I4 connected to the high-pressure air storage tank 5 is opened. The high-pressure air compressor 1 generates compressed air and transmits it to the combined dryer 2, so that the air is dried and filtered, and the compressed air is transmitted to the inside of the high-pressure air storage tank 5 through the pipe body I3. At the same time, the gate valve II7 between the high-pressure air storage tank 5 and the working equipment 9 is opened to transmit the high-pressure air to the inside of the working equipment 9 for use, and the check valve 6 prevents air from flowing back.

[0021] When high-pressure air is needed, the gate valve I4 on the high-pressure gas storage tank 5 connected to the pipe body I3 is closed, and the gate valve I4 on the low-pressure gas storage tank 12 connected to the pipe body I3 is opened, so that the high-pressure air generated by the high-pressure air compressor 1 passes through the pipe body I3 to connect the low-pressure gas storage tank 12, and the diameter of the pipe is larger than the diameter of the pipe body I3 to connect the high-pressure gas storage tank 5, so that the gas pressure is reduced and transported to the low-pressure gas storage tank 12. While being transported into the low-pressure gas storage tank 12, the pressure gauge 8 detects the gas pressure. When the detected gas pressure is small, the boosting valve 10 is used to boost the pressure and transport the pressurized gas to the inside of the low-pressure gas storage tank 12, and the gate valve II7 on the low-pressure gas storage tank 12 connected to the working equipment 9 is opened, so that the low-pressure gas inside the low-pressure gas storage tank 12 is transported to the inside of the working equipment 9 for work, and the pressure gauge of the low-pressure gas storage tank 12 is used to detect the pressure inside the low-pressure gas storage tank 12 in real time, and the pressure output by the low-pressure gas storage tank 12 is adjusted through the cooperation of the pressure reducing valve 13, so that the working equipment 9 can use gases of different pressures to work.
