Abstract

The invention discloses an absorption tower upper cover assembly of an oxygen producing machine, which comprises an absorption tower upper cover. An airway connection plate is hermetically mounted at the bottom of the absorption tower upper cover; a compressed air inlet and a nitrogen discharging opening are formed on the airway connection plate; a pneumatic valve is mounted on the lateral surface of the absorption tower upper cover; and a pilot-operated solenoid valve is arranged on the pneumatic valve. The product adopts integral formation, and reduces the connections of pipelines among components of the absorption tower upper cover, thereby reducing pressure loss. In addition, the invention is favorable for micromation of the oxygen producing machine, so as to enable the structure of the absorption tower upper cover of the oxygen producing machine to be more compact, thereby simplifying installation steps, and improving the sealing performance and the reliability of the system. Furthermore, the invention can be widely applied to production of the absorption tower upper cover of the oxygen producing machine.

Description

technical field [0001] The invention relates to a component of an oxygen generator, in particular to an integration of an upper cover of an adsorption tower of an oxygen generator. Background technique [0002] In recent years, due to the rapid development of pressure swing adsorption (PSA) technology, the application field of pressure swing adsorption oxygen production is also becoming wider and wider. Pressure swing adsorption (PSA) air separation oxygen production technology is based on the difference in the adsorption capacity of the adsorbent for oxygen and nitrogen in the air to achieve the separation of oxygen and nitrogen. When air enters the bed layer with adsorbent, nitrogen is adsorbed with strong adsorption capacity, but oxygen is not adsorbed, so that a high concentration of oxygen can be obtained at the outlet end of the adsorption bed. At present, the pneumatic valves, the upper cover of the double tower and various connecting airway pipelines in the pressure...
