Electrified insulator dry ice cleaning machine

Abstract

The invention relates to the technical field of dry ice cleaning equipment, and discloses an electrified insulator dry ice cleaning machine which comprises a material pushing mechanism, a pre-crushed ice rotating disc mechanism, a crushed ice particle adjusting mechanism, a high-pressure ice discharging device, a flow dividing valve and a semi-ring double-spraying mechanism. The semi-ring double-spraying mechanism comprises a semi-ring bottom plate, a lifting part is arranged on the semi-ring bottom plate, dry ice nozzles are arranged at the two ends of the semi-ring bottom plate through guide parts so that the lifting part can drive the dry ice nozzles to move up and down on the guide parts, and an electrified insulator cleaning area is formed between the dry ice nozzles and the semi-ring bottom plate. Ice inlets of the dry ice nozzles at the two ends are connected with spiral crushed material feeders, so that dry ice particles are conveyed into the dry ice nozzles at a high speed through the spiral crushed material feeders; according to the electrified insulator dry ice cleaning machine, the ice nozzle ascends and descends up and down for cleaning back and forth, an insulator is driven to be quickly cleaned in an electrified insulator cleaning area, the cleaning efficiency is high, no lifting equipment needs to be additionally matched for operation, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of insulator cleaning equipment, in particular, to a dry ice cleaning machine for charged insulators. Background technique [0002] Dry ice is solid carbon dioxide and is widely used in various cleaning applications due to its excellent cleaning properties. The cleaning system sprays the dry ice particles of the dry ice cleaning machine to the working surface to be cleaned through high-pressure air, and the dry ice particles sublime to CO at the moment of contacting the working surface 2 The gas absorbs a lot of heat, and the surface dirt suddenly cools down, causing the surface to become embrittled or even burst. At the same time, these extremely low-temperature dry ice particles enter the dirt cracks, sublime within a few thousandths of a second, and their volume instantly expands 600-800 times. The effect of peeling the dirt off the surface of the object is like a "micro-explosion", and due to the instan...

Problems solved by technology

[0004] In the above-mentioned structure, it is used for dry ice cleaning of live insulators, but the disclosed structure uses the rack to rotate in the limit guide column to drive the dry ice spray head to rotate and clean, but since the live insulator is in the shape of a bar, the dry ice spray head The cleaning work can only be done on the same plane. During the cleaning process, it needs to cooperate with other independent equipment for lifting and cleaning. At the same time, the dry ice transportation process is longer, and the sufficient injection pressure must be achieved, which makes the structure of the entire cleaning equipment more complex and more costly. high
