The invention discloses a solid CO2 particle spray cleaning device, which relates to the technical field of dry ice cleaning. The key points of the technical solution are: comprising a dry ice granulation mechanism, a dry ice collision channel and a centrifugal separator, and a dry ice collision part is arranged in the dry ice collision channel , the centrifugal separator is connected with a dry ice particle pipe and a dry ice particle recovery pipe, the dry ice particle pipe and the dry ice particle recovery pipe are connected with a protective power flow pipe, and the dry ice particle pipe is connected with a dry ice cleaning spray gun, so The dry ice particle recovery pipe is connected to the dry ice collision channel, the dry ice cleaning spray gun is connected with a nozzle, a dry ice particle mixing chamber is provided between the dry ice cleaning spray gun and the nozzle, and a mixing and stirring device is provided in the dry ice particle mixing chamber . The invention can screen the dry ice particles after collision, provide dry ice particles with relatively similar uniformity and size for spray cleaning, and the dry ice particles are uniformly dispersed during spraying, which has the advantage of improving the effect of dry ice spray cleaning.

Description

technical field [0001] The invention relates to the technical field of dry ice blasting, more specifically, it relates to a solid CO 2 Particle jet cleaning device. Background technique [0002] Dry ice is solid CO 2 In addition to the dry ice cleaning technology developed in the prior art to clean the workpiece, compressed air is used as the power and carrier to spray dry ice particles onto the surface of the workpiece to be cleaned, thereby cleaning the workpiece. [0003] For example, the authorized announcement number is CN201049331Y, and the Chinese patent whose announcement date is 2008.04.23 discloses a particle dry ice spray cleaning gun, including a handle, and a gun barrel connecting the dry ice blasting device and the gun head. Dry ice impact parts for dry ice. [0004] After the dry ice particles are sent into the gun barrel, they collide with the dry ice collision parts multiple times, so that the dry ice particles are refined, and then sprayed out of the gun...

Problems solved by technology

However, the dry ice particles produced during the dry ice collision process are of different sizes and have not been sieved, so that some dry ice particles with incomplete collisions are also ejected together with the dry ice particles, resulting in poor dry ice cleaning effect, and the dry ice is directly ejected after the collision, resulting in The uneven mixing of dry ice and conveying gas makes the sprayed dry ice particles not uniform enough, which affects the cleaning effect of dry ice
