Ultrasonic steam bath cleaning machine for plane oxygen system accessories

Abstract

The invention discloses an ultrasonic steam bath cleaning machine for plane oxygen system accessories. The ultrasonic steam bath cleaning machine comprises an electrical control device, a conveying mechanism , a cleaning system and a hot-air drying system, wherein the cleaning system and the hot-air drying system are arranged in the same sealed housing; an openable and closeable feed opening and an openable and closeable discharging opening are formed in the housing; the cleaning system comprises ultrasonic crude cleaning tanks, ultrasonic fine cleaning tanks and steam-bath cleaning tanks which are sequentially arranged from front to back; the feed opening is close to the ultrasonic crude cleaning tank; the hot-air drying system is positioned behind the cleaning system; the discharging opening is close to the hot-air drying system; the conveying mechanism comprises a track arranged above the cleaning system and the hot-air drying system, a mechanical hand arranged on the track and a driving mechanism used for driving the mechanical hand to move transversely and vertically; and the electrical control device is used for controlling a cleaning basket to enter from the feed opening, then controlling the cleaning basket to be grasped and fed into all cleaning tanks sequentially by the mechanical hand, cleaned in the cleaning tanks, and subjected to hot-air drying by the hot-air drying system and finally controlling the cleaning basket to be discharged from the discharging opening. The ultrasonic steam bath cleaning machine is good in cleaning effect and can ensure that the cleanliness of cleaned workpieces meets requirements.

Description

technical field [0001] The invention relates to maintenance equipment for an oxygen system of a civil aviation aircraft, in particular to an ultrasonic steam bath cleaning machine for an accessory of an aircraft oxygen system. Background technique [0002] Although oxygen cannot be burned directly, any object will become extremely flammable in an oxygen-containing environment, especially in a high-concentration oxygen environment, so oxygen is a dangerous gas. Aircraft oxygen system accessories are parts that are in direct contact with oxygen. In the process of maintaining oxygen system parts, the most important thing is to clean the parts. According to the requirements of the "Maintenance Manual", the cleanliness of parts in direct contact with oxygen is very high, and the NVR (NonVolatileResidue) must be less than 1.0 mg / square foot. [0003] At present, the traditional way of cleaning oxygen system parts is to use general ultrasonic cleaning equipment and use the cleanin...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional way of cleaning oxygen system components is to use general ultrasonic cleaning equipment and cleaning agents specified in the "Maintenance Manual". The time is long, and the cleaning efficiency is very low; (2) the cleaning agent consumes a lot and the cleaning cost is high; (3) the solvent cleaning agent has strong volatility, which not only pollutes the environment, but also endangers human health
