Abstract

The invention discloses a screw extrusion centrifugal acceleration dry ice pill cold jet cleaner comprising a cylindrical dewar vessel, an inlet and an outlet are provided on the cylindrical dewar vessel, a spiral feeder is arranged in the inner cavity of the cylindrical dewar vessel, which periphery is provided with a heat exchanger, the inner cavity of the cylindrical dewar vessel is communicated with the liquid CO2 feed port. A bottom plate with an opening is installed at a discharge port on the lower end of the cylindrical dewar vessel, a box body is arranged below the bottom plate, an opening is provided on the side wall of the box body, a rotable disc is horizontally arranged in the box body and is connected with a centrifugal blade which is disposed right below the bottom plate. Compared with the existing technology, the invention increases the dry ice forming efficiency and outlet jetting speed, expands the effective area for cleaning the dry ice, is especially suitable for performing clean operation onto the huge device which is inconvenient to move and disassemble; the dry ice forming and acceleration process are integrated into one system, accordingly, the invention is convenient to move and use, and is low in system noise.

Description

Technical field [0001] The invention relates to the technical field of dry ice cleaning, in particular to a cold jet cleaning machine for spiral extrusion and centrifugal acceleration of dry ice pellets. Background technique [0002] At present, traditional physical and chemical cleaning methods are still mainly used in the cleaning industry in our country. Because traditional physical cleaning methods often damage the surface of cleaning objects, chemical cleaning will bring headaches to secondary pollution problems. Dry ice cold jet cleaning technology can overcome the shortcomings of traditional cleaning technology. It is a true green cleaning technology. It can quickly clean grease, carbon, scale, rust, ink, adhesive, mold release agent, rubber sintering Various dirt, such as solder slag on circuit boards, can also be cleaned without contact on uneven surfaces. After cleaning, dry ice is directly sublimated and released into the air without causing secondary pollution. The ad...
