Embodiment Construction

[0019] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0020] Such as figure 1 As shown, a dry ice blasting device includes a compressed air nozzle 100, a mixing chamber 200, an oscillation chamber 300, a diffuser pipe 400, and a collision wall 500. The mixing chamber 200 is provided with an installation through hole 210 and a dry ice inlet 220. The compressed air nozzle 100 is embedded in the installation through hole 210, the mixing chamber 200 communicates with the oscillation chamber 300 through the dry ice injection channel 600, the oscillation chamber 300 is provided with a dry ice outlet 310, and the diffusion pipe 400 is installed on the dry ice At the outlet 310 , the collision wall 500 is disposed in the oscillation chamber 300 and is opposite to the dry ice injection channel 600 . The compressed air nozzle 100 is used to be connected with an air delivery pipeline so as to inject compressed air. A dry ...

Abstract

The invention discloses a dry ice spraying device which comprises a compressed air nozzle, a mixing chamber, an oscillating cavity, a diffusion pipe and a collision wall. A mounting through hole and a dry ice inlet are arranged on the mixing chamber, the compressed air nozzle is embedded in the mounting through hole, the mixing chamber is communicated with the oscillating cavity through a dry ice spraying-in passage, a dry ice outlet is arranged on the oscillating cavity, the diffusion pipe is mounted at the dry ice outlet, and the collision wall is arranged in the oscillating cavity and is opposite to the dry ice spraying-in passage. Two-throat-pipe spraying is adopted, so that conveying of dry ice particles is less prone to blockage when the dry ice spraying device works, continuous and smooth feeding of the dry ice particles is realized, and working efficiency is improved; the oscillating cavity is designed, and by self-excitation oscillating structure conditions and continuous border conditions of the oscillating cavity, continuous dry ice spray flow can be converted into pulse spray flow, spraying distance is long, and continuous quantity is large. The invention discloses a dry ice spraying method adopting the dry ice spraying device.

Description

technical field [0001] The invention relates to the technical field of dry ice blasting, in particular to a dry ice blasting device and method. Background technique [0002] Traditionally, dry ice cleaning equipment can only spray dry ice particles in a short distance due to its spraying device, which has low work efficiency and consumes manpower; moreover, the transportation of dry ice particles is easy to block, and it is difficult to continuously supply dry ice particles, which is likely to cause delays in cleaning work; in addition, due to the traditional The injection device of dry ice cleaning equipment has low injection pressure and weak impact force, making it difficult to clean heavily polluted working objects. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a dry ice blasting device, which can not only realize long-distance spraying and improve work efficiency, but also has high spraying ...
