Problems solved by technology

But these cleaning methods have defects: (Ultra) high pressure water cleaning method cannot be used on electrical equipment or equipment near electrical equipment, and will produce waste water, and cause thin rust on the surface of metal equipment
Power tool cleaning can only be used for smooth and simple surface shapes, and will cause damage and damage to the surface; manual tool cleaning is not suitable for equipment that requires large-scale and frequent cleaning, and the cleaning efficiency is too low and will damage the equipment
Moreover, no matter which of the above cleaning methods is used, the equipment to be cleaned needs to be shut down for maintenance, which will greatly affect the work efficiency

Embodiment Construction

[0020] refer to figure 1 as shown, figure 1 A structural diagram of a dry ice blasting machine according to an embodiment of the present invention is disclosed. The dry ice blasting machine includes: a dry ice container 102 , a compressed air generator 104 and an ejector 106 .

[0021] Dry ice pellets 121 are stored in the dry ice container 102 . In one embodiment, the dry ice particles 121 are cylinders with a diameter of 2.8mm˜3.2mm and a length of 2.5mm˜10mm. The dry ice particles are prepared through the following process: firstly, carbon dioxide is condensed into a colorless liquid at a temperature of 20±5°C and a pressure of 6000 kPa. Then, the liquid formed by the above-mentioned condensation evaporates rapidly under low pressure, and condenses into an ice-snow-like solid substance, that is, dry ice. Put the dry ice into the mold, and press it through the abrasive tool to form dry ice particles with a diameter of 2.8 mm to 3.2 mm and a length of 2.5 mm to 10 mm.

Abstract

The invention provides a dry ice cleaning machine which comprises a dry ice container, a compressed air generator and a jetting device. Dry ice particles are stored in the dry ice container. A compressed air flow is generated by the compressed air generator and is inputted into the dry ice container. The dry ice particles are carried by the compressed air flow and are jetted by the jetting device to form a jet flow. The jet flow is jetted toward a to-be-cleaned surface. The to-be-cleaned surface is cleaned with the dry ice particles. The to-be-cleaned surface is cleaned with the jetted dry ice particles, and the cleaning purpose is achieved by means of air flow jetting energy and transient evaporation energy of the dry ice particles. The dry ice particles transiently evaporate into carbon dioxide under normal temperature and normal pressure, the environment is not polluted, the dry ice cleaning machine only needs to be halted, and the influence on the production efficiency is little.

Description

technical field [0001] The present invention relates to surface cleaning technology, more particularly, relates to a kind of dry ice cleaning technology for cleaning painted surface. Background technique [0002] In the car manufacturing process, the painting process is an essential part. The painting process is carried out in the painting workshop. A large number of paint particles will inevitably adhere to the equipment and walls in the painting workshop, causing pollution. Therefore, the painting workshop needs to be cleaned regularly. [0003] The traditional cleaning method is to use (ultra) high pressure water cleaning, solvent cleaning, power tool cleaning, hand tool cleaning and other methods to clean the paint spraying workshop. However, there are defects in these cleaning methods: the (ultra)high pressure water cleaning method cannot be used on electrical equipment or equipment near electrical equipment, and will generate waste water and cause thin rust on the sur...
