Abstract

The invention relates to a treatment device and a treatment method, and discloses a dry ice particle treatment device and a dry ice particle treatment method to solve the problems that the conventional dry ice particles are high in particle diameter and high in destructive power, and can not clean an instrument or an equipment having higher requirement on the accuracy, resulting in a blank of particle cleaning in the dry ice cleaning industry in China. The dry ice particle treatment device comprises an outer housing, a first pipeline, a second pipeline, a third pipeline, a throat pipe and a sieve plate, wherein the first pipeline, the second pipeline and the third pipeline are arranged in the outer housing; one end of the first pipeline is connected with a discharge port of a feeding assembly; the other end of the first pipeline is vertically communicated with one end of the second pipeline; the other end of the second pipeline is vertically communicated with the third pipeline; the throat pipe is arranged in the first pipeline; and the sieve plate is vertically mounted on the second pipeline in an inserting manner. The dry ice particle treatment method comprises the steps of setting a position of the outer housing, conveying materials, carrying out four times of crushing, and outputting the particles. The dry ice particle treatment device and the dry ice particle treatment method are applied to the crushing treatment of the 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...
