Automatic drainage device of compressed air pipeline

Abstract

The invention discloses an automatic drainage device of a compressed air pipeline. A segment of the compressed air pipeline is cut down and connected through a curved pipe, the middle segment of the curved pipe is bent downward, and a diversion pipe is connected to the bottom of the middle segment of the curved pipe; a filter is arranged on the diversion pipe, the bottom of the diversion pipe is connected to an inlet end of a two-position three-way solenoid valve, and two outlet ends of the two-position three-way solenoid valve are connected with two water collection and drainage pipelines respectively; each water collection and drainage pipeline includes a water collection pipe, a water storage tank and a drainage pipe which are connected from top to bottom in sequence, photoelectric switches are arranged on the water storage tanks, each drainage pipe is provided with a first fast opening ball valve and a drainage solenoid valve from top to bottom in sequence, the bottoms of the waterstorage tanks of the two water collection and drainage pipelines are communicated with each other through a horizontal communication pipe which is provided with a second fast opening ball valve, andthe photoelectric switches and all the solenoid valves are electrically connected with a controller. The automatic drainage device has the advantages of being free of gas loss, unlikely to be clogged,high in automation degree and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of compressed air water removal, in particular to an automatic drainage device for compressed air pipelines. Background technique [0002] Compressed air is the second largest power source next to electricity, and it is also a process gas source with multiple uses. Different fields of application have different requirements for the quality of compressed air, but moisture content is one of the most important quality indicators. [0003] In industrial applications, due to the widespread presence of moisture in the ambient air and the influence of comprehensive factors such as air compressor pipelines and water removal equipment, compressed air always contains a certain amount of moisture. As the temperature and pressure change, condensed water will precipitate in the pipeline. If it cannot be drained in time, it will easily damage the pneumatic control components and related instruments of the terminal equipm...
