Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] The high-efficiency carbon dioxide snow spray gun provided by the present invention includes a housing 3, an interconnected carbon dioxide expansion chamber 4 and a compressed air chamber arranged in the housing 3, a mixing nozzle 1 arranged at the front end of the housing 3, and the rear of the housing 3 The carbon dioxide inlet 6 and the compressed air inlet 9 at the end, the inner wall of the carbon dioxide expansion chamber 4 is provided with a spiral groove 5, the spiral groove 5 is arranged along the entire carbon dioxide expansion chamber 4, so that carbon dioxide enters the carbon dioxide expansion chamber along the spiral groove 5 4, effectively extending the entry path of carbon dioxide and improving the phase transition conversion rate of carbon dioxide;

[0013] The compressed air cavity is composed of a straight cylindrical cavity 11 and a conical c...

Abstract

The invention provides an efficient carbon dioxide snow spray gun. The efficient carbon dioxide snow spray gun comprises a casing, a carbon dioxide expansion cavity, a compressed air cavity, a mixing nozzle arranged at the front end of the casing as well as a carbon dioxide inlet and a compressed air inlet which are arranged at the rear end of the casing, wherein the carbon dioxide expansion cavity and the compressed air cavity are formed in the casing and mutually communicate. The efficient carbon dioxide snow spray gun is characterized in that a spiral slot is formed in the inner wall of the carbon dioxide expansion cavity. After the spiral slot is formed in the inner wall of the carbon dioxide expansion cavity, when sent high-pressure carbon dioxide gas is rapidly decompressed in the carbon dioxide expansion cavity and has phase change, the phase change route of carbon dioxide is effectively prolonged due to arrangement of the spiral slot, more carbon dioxide has phase change, small-particle solids are formed, the phase change conversion rate of carbon dioxide is increased, and the efficient cleaning requirement is met. The efficient carbon dioxide snow spray gun is simple in structure, convenient to use and remarkable in cleaning effect.

Description

technical field [0001] The invention relates to a carbon dioxide snow spray gun, in particular to a high-efficiency carbon dioxide snow spray gun, and belongs to the technical field of design and manufacture of electric cleaning equipment. Background technique [0002] Due to the characteristics of high efficiency, wide application range and no pollution, carbon dioxide cleaning technology has a wide range of applications in the mold, power electronics, petrochemical and automotive industries. Carbon dioxide is a colorless, odorless, non-flammable, insulating and inert gas. When the pressurized carbon dioxide liquid loses its pressure, a phase transition will occur. Under the Joule-Thompson effect, the expanding carbon dioxide gas will become colder, making a part of the carbon dioxide The gas turns into a solid state, creating "carbon dioxide snow." Carbon dioxide snow cleaning is to use the high-speed carbon dioxide small particle airflow formed during the rapid decompres...
