Ultrasonic vibration automatic deicing device and method

Abstract

The invention discloses an automatic supersonic vibration deicing device and method, and relates to a deicing device and method used for a low-temperature medium conveying system. The automatic supersonic vibration deicing device and method are good in deicing effect, high in efficiency, easy to operate, safe to use and high in generality; the automatic supersonic vibration deicing device comprises an annular retaining frame (1), at least two air cylinders (2) are fixedly arranged on the retaining frame and are circumferentially and evenly arranged along the center of the retaining frame, and supersonic vibrators (3) are fixedly connected to piston rods; the deicing method of the automatic supersonic vibration deicing device is used and comprises following steps: the automatic supersonic vibration deicing device is aligned with the low-temperature medium conveying system; the air cylinders automatically propel the supersonic vibrators to make contact with the low-temperature medium conveying system; the supersonic vibrators alternatively work in a cycle manner; according to the deicing effect, the gas supply pressure of all air cylinder positive cavities is adjusted until deicing is completed; gas supply openings of air cylinder reverse cavities are ventilated, and the supersonic vibrators retreat in a reverse manner.

Description

technical field [0001] The invention relates to the field of automatic low-temperature medium transportation, in particular to a deicing device and method for a low-temperature medium transportation system. Background technique [0002] In aerospace, aviation, LNG and other fields, low-temperature medium delivery systems are widely used to transport low-temperature medium (liquid hydrogen, liquid oxygen, liquid natural gas, etc.) to launch vehicle storage tanks, automotive LNG cylinders and other containers. In the process of low-temperature transportation, under the action of low-temperature medium, moisture in the natural environment can easily cause frost and ice on the surfaces of equipment such as injectors, connectors, liquid filling guns, and valves in the transportation system, which affects the low temperature. Normal disengagement of the media delivery system. In addition, when severe icing occurs in the low-temperature medium delivery system, the operator needs t...

Problems solved by technology

In the process of low-temperature transportation, under the action of low-temperature medium, moisture in the natural environment can easily cause frost and ice on the surfaces of equipment such as injectors, connectors, liquid filling guns, and valves in the transportation system, which affects the low temperature. Normal disengagement of the media delivery system

In addition, when severe icing occurs in the low-temperature medium conveying system, the operator needs to remove the ice through mechanical force. The deicing efficiency is low, which will affect the secondary docking process and easily lead to safety accidents such as explosions.
