Novel dry ice cleaning device

Abstract

The invention discloses a novel dry ice cleaning device. The device comprises a base, a hopper, an ice preparing wheel, an electric motor, a mandrel, a half-shaft pushing air connecting pipe and a dry ice blowing air connecting pipe; an ice inlet and an ice outlet are arranged at the top and the bottom of the base respectively; the hopper is arranged at the top of the ice inlet; the ice preparing wheel is in a hollow cylindrical structure, ice preparing holes are formed in an axial circumferential face of the ice preparing wheel in a staggered mode, the ice preparing wheel is rotatably arranged at the center of the base, and the electric motor is connected with the ice preparing wheel through a rotating shaft; the mandrel comprises a first half shaft and a second half shaft; the first half shaft is in key connection with the second half shaft, and the mandrel is arranged at the center of the ice preparing wheel; the half-shaft pushing air connecting pipe and the dry ice blowing air connecting pipe are arranged outside the base. By the aid of the device, the problem of icing blockage of the ice preparing holes in the prior art can be effectively solved, and meanwhile, the jetting force of dry ice particles is increased.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a novel dry ice cleaning device. Background technique [0002] Dry ice blasting is to use the compressed air generated by a specially equipped air compressor or a compressed air system; the prepared dry ice particles are loaded into the cleaning equipment, and driven by the compressed air, the high-density dry ice particles are impacted with the compressed air. The surface of the object to be cleaned achieves the purpose of decontamination. The principle of dry ice cleaning is to use high-speed solid carbon dioxide particles to impact the surface of the object to be cleaned. Since the dry ice particles are in an extremely low temperature state, the temperature difference between the dry ice particles and the surface of the workpiece is extremely large, forming a "thermal shock". Under the action of the two energies of thermal shock energy, it reaches the bottom of the...
