Solid CO2 cleaning and spraying device

Abstract

The invention discloses a solid CO2 cleaning nozzle device, and relates to the technical field of dry ice cleaning. The technical scheme adopted by the device is characterized in that the solid CO2 cleaning nozzle device comprises a gun barrel and a gun handle connected to the gun barrel; a nozzle is arranged at one end of the gun barrel; an air ice inlet communicated with the interior of the gunbarrel is formed in the nozzle; the gun barrel comprises a connecting pipe connected with the gun handle and a nozzle pipe penetrating through the connecting pipe; one end of the nozzle pipe is connected and communicated with the nozzle; an elastic piece used for buffering spray force of the spray pipe is arranged in the connecting pipe; a thrust device used for providing recoil force is arrangedon the connecting pipe; a heat insulation layer is arranged on the inner wall of the connecting pipe; a heat preservation sleeve is arranged on the gun handle; and a heat preservation sleeve heating piece is arranged in the gun handle. According to the solid CO2 cleaning nozzle device, recoil force can be reduced; a user can hold the gun handle comfortably; freezing and fatigue are avoided; and aneffect of improving the use comfort of the gun handle is achieved.

Description

technical field [0001] The invention relates to the technical field of dry ice blasting, more specifically, it relates to a solid CO 2 Clean spray unit. Background technique [0002] Dry ice blasting is a method of cleaning dirt. Dry ice blasting (solid carbon dioxide cleaning) is called cold spray, which uses compressed air as the power and carrier, and dry ice particles as accelerated particles, which are sprayed onto the surface of the object by a special jet cleaning machine. Cleaning the surface of the object, using the momentum change (Δmv), sublimation, melting and other energy conversion of the high-speed moving solid dry ice particles, so that the dirt, oil, residual impurities, etc. on the surface of the cleaned object are quickly frozen, so that they are condensed, embrittled, and peeled off. And at the same time cleared with the airflow. Existing solid-state carbon dioxide cleaning machines are usually equipped with spray guns for convenient operation and clean...

AI Technical Summary

Problems solved by technology

However, the temperature of dry ice is usually low, and the user directly holds the handle of the gun, which is easy to suffer from freezing and fatigue under long-term use, and the recoil force of the spray gun is relatively large, and the user needs a large grip force when using it, and it is easy to get tired after long-term use. time consuming for users
