Abstract

A dry ice particle processor and a dry ice particle processing method relate to a processor and a processing method thereof. The present invention solves the problem that existing dry ice particles have larger particle diameters and greater destructive power, and cannot clean instruments or equipment with high precision requirements, resulting in blank particle cleaning in the domestic dry ice cleaning industry. A dry ice particle processor comprises an outer shell, a first pipeline, a second pipeline, a third pipeline, a throat and a sieve plate, the first pipeline, the second pipeline and the third pipeline are respectively arranged in the housing, and one end of the first pipeline It is connected with the discharge port of the feeding assembly, the other end of the first pipe is vertically connected with one end of the second pipe, the other end of the second pipe is vertically connected with one end of the third pipe, and the throat is set on the first pipe Inside, the sieve plate is inserted vertically on the second pipe. Processing method: set the position of the outer shell; convey and feed the material; crush four times; output the particles. The invention is used for crushing treatment of dry ice particles.

Description

technical field [0001] The invention relates to a dry ice particle processor and a processing method for dry ice particles. Background technique [0002] The temperature of dry ice particles is extremely low (-78°C). Such a low temperature makes it have unique thermodynamic properties, which affect the mechanical properties of adhered dirt. Due to the temperature difference between the dry ice particles and the cleaning surface, when the dry ice particles are in contact with the material, thermal shock occurs, the temperature of the material decreases, the brittleness increases, and physical changes occur, so that the dry ice particles can impact and break the dirt layer. [0003] The characteristic of dry ice blasting is that the dry ice particles vaporize at the moment of impact, and the momentum of the dry ice particles disappears at the moment of impact. Rapid heat exchange occurs between the dry ice particles and the cleaning surface to achieve solid CO 2 Rapid sublim...
