Embodiment Construction

[0029] refer to Figure 1 to Figure 4 For solid CO 2 Cleaning the nozzle unit is further explained.

[0030] a solid CO 2 Clean the spray head unit, such as figure 1 As shown, it includes a gun barrel 1 and a gun handle 2 connected to the gun barrel 1. One end of the gun barrel 1 is provided with a nozzle 3, and the nozzle 3 is provided with an air ice inlet 31 communicating with the inside of the gun barrel 1, and the dry ice is passed through a pneumatic Push it into the air ice inlet 31, so as to enter the spray head 3 and spray out through the gun barrel 1, so as to be used for cleaning.

[0031] Such as figure 1 As shown, the gun barrel 1 includes a connecting pipe 11 connected to the gun handle 2 and a nozzle pipe 12 passing through the connecting pipe 11. One end of the nozzle pipe 12 is connected and communicated with the spray head 3, and the connecting pipe 11 is provided with a buffer injection pipe. An elastic member 113 for spraying force, and the connecting ...

Abstract

The invention discloses a solid CO 2 The nozzle cleaning device relates to the technical field of dry ice blasting. The key points of the technical solution are: it includes a gun barrel and a gun handle connected to the gun barrel. One end of the gun barrel is provided with a nozzle. The air ice inlet, the gun barrel includes a connecting pipe connected with the gun handle and a nozzle pipe passing through the connecting pipe, one end of the nozzle pipe is connected and communicated with the spray head, and the connecting pipe is provided with a buffer for spraying the spray pipe. force, and the connecting pipe is provided with a thrust device for providing recoil force, the inner wall of the connecting pipe is provided with a heat insulation layer, the handle of the gun is provided with a thermal insulation cover, and the inner wall of the handle of the gun is provided with a heat insulating layer. A heat preservation jacket heating element is provided. The invention can reduce the recoil force, provide the user with a comfortable handle to hold the gun, avoid fatigue from being exposed to cold, and have the effect of improving the user comfort.

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...
