a solid co 2 the cleaning method

Abstract

The invention discloses a solid CO2 cleaning method, which relates to the technical field of dry ice cleaning. The key points of the technical solution are as follows: S1, selecting an intelligent dry ice cleaning machine, and the intelligent dry ice cleaning machine is equipped with an image acquisition device and a display device; S2, Select the dry ice spray gun to be connected with the dry ice blasting machine, and the spray port of the dry ice spray gun is provided with a nozzle and a shifting mechanism; S3, transmit the alignment image of the dry ice spray gun to the display device; S4, judge the shape of the workpiece and the degree of dirt through the display device, and set Set the cleaning parameters, and control the shifting mechanism to switch nozzles for use; S5, turn on the intelligent dry ice blasting machine to clean the workpiece; S6, judge whether the cleaning is clean through the display device, if so, end the cleaning, if not, cycle step S4 until the cleaning is clean . The invention can perform visual cleaning, adjust the nozzle shape and cleaning parameters according to the cleaning environment, is flexible and convenient, and has the advantages of improving the cleaning effect.

Description

technical field [0001] The invention relates to the technical field of cleaning, more specifically, it relates to a solid CO2 cleaning method. Background technique [0002] The common cleaning methods are high-pressure water cleaning and abrasive cleaning, etc. The main cleaning medium is likely to cause the equipment to fail. Therefore, the dry ice cleaning method is disclosed in the prior art. By spraying dry ice onto the surface of the object to be cleaned, the energy conversion such as momentum change, sublimation, and melting of solid dry ice particles moving at high speed is used to make the dirt, oil, and residue on the surface of the object to be cleaned Impurities, etc. are frozen quickly, so as to coagulate, embrittle, and be stripped, and at the same time, they are removed with the clear flow, which will not cause any damage to the surface of the object to be cleaned, especially the metal surface, and will not affect the smoothness of the metal surface.

Problems solved by technology

However, the structure of each cleaning workpiece is different, and some may need to be inserted into the inside of the workpiece for cleaning. However, in the existing dry ice cleaning method, it is a blind operation when cleaning the inside of the workpiece, and it is impossible to accurately judge the cleaning situation. Narrow, the shape of the nozzle is single during cleaning, and it cannot be adjusted flexibly according to the environment, resulting in inflexible and convenient use and affecting the cleaning effect
