Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a vortex ring. Background Art

[0002] With the rapid development of the manufacturing industry, the requirements for product quality are getting higher and higher. Laser welding and cutting, as a widely used process, play a vital role in products. During the laser welding and cutting process, foreign matter such as welding slag and dust will be generated, which will directly or indirectly cause product defects. If these foreign matter are not handled, once defects occur, the entire product will be scrapped, greatly increasing production costs and increasing the burden on factory operations.

[0003] Based on this background, some factories will use negative pressure vacuuming to suck away foreign matter, but according to actual feedback, foreign matter generated during welding cannot be completely removed, and there is no obvious effect on improving product yield; in order to solve the above problems, positive pressure blowing is used to blow up foreign matter, and negative pressure is used to suck up foreign matter for dust removal. In order to improve the effect of positive pressure blowing on foreign matter, a vortex ring is designed to form a vortex airflow, thereby improving the effect of blowing away foreign matter.

[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a vortex ring, comprising:

[0025] The ring body 1 is arranged inside the positive pressure cavity 8 formed by the inner ring 5 and the spacer ring 6, and the ring body 1 is located below the gas outlet end of the positive pressure pipe joint 9;

[0026] The inner wall of the ring body 1 is in close contact with the outer wall of the inner ring 5, and the outer wall of the ring body 1 is in close contact with the inner wall of the spacer ring 6;

[0027] A guide hole 2 is arranged on the surface of the ring body 1. The guide hole 2 is arranged obliquely, and the air outlet end of the guide hole 2 passes through the bottom surface of the ring body 1. There are multiple guide holes 2, and the multiple guide holes 2 are evenly distributed around the circumference with the axis of the ring body 1 as the reference.

[0028] In this embodiment, when in use, the positive pressure pipe joint 9 is connected to the blowing pump, and air is blown into the positive pressure chamber 8 through the air outlet pump and the positive pressure pipe joint 9. The air flow inside the positive pressure chamber 8 enters the guide hole 2. Due to the inclined setting and the multiple guide holes 2 being evenly distributed around the axis of the ring body 1 as the reference circle, the air flow forms a vortex airflow under the guidance of the guide holes 2. The vortex airflow is blown toward the foreign matter through the bottom port of the positive pressure chamber 8. The foreign matter is blown up by the vortex airflow, which has a good blowing effect and helps to improve the dust removal effect.
