[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] Example 1

[0021] In this embodiment, a swirl nozzle is used for a spark extinguishing device in a dust removal system, such as Figure 1 and Figure 2As shown. It includes a cyclone cap body 1, a base 2, a nozzle 3 and a cyclone cap body connecting seat 8; the base 2 and the cyclone cap body connecting seat 8 are connected via a spiral interface 4, the cyclone cap body 1 is connected to the cyclone cap body connecting seat 8, and the cyclone cap body 1 and the cyclone cap body connecting seat 8 can rotate relative to each other. In this embodiment, the cyclone cap body 1 and the cyclone cap body connecting seat 8 are connected via a bearing, so that the cyclone cap body 1 and the cyclone cap body connecting seat 8 can rotate relative to each other. The top of the cyclone cap body 1 is connected to the nozzle 3, as shown Figure 1 As shown, in this embodiment, the number of nozzles 3 is 3, and the angle between the nozzle 3 and the swirl cap body 1 is 90°; the nozzle 3 is connected to the external fluid through a pipe 5; the swirl cap body 1 is provided with a plurality of swirl openings 6 for the fluid to pass through. In the dust removal system, since the internal dust gas flows in a directional manner, the flowing gas passes through the swirl openings 6, thereby driving the swirl cap body 1 to rotate.

[0022] like Figure 2 As described above, in this embodiment, a pipe connecting seat 7 is provided inside the cyclone cap body connecting seat 8, and the pipe connecting seat 7 is connected to the middle of the pipe 5. The function of the pipe connecting seat 7 in this embodiment is to prevent the rotation of the cyclone cap body 1 from driving the pipe 5 to rotate, causing the pipe 5 to twist or the cyclone cap body 1 to be difficult to rotate due to the excessive hardness of the pipe 5.

[0023] like Figure 3 As shown, the pipe connection seat 7 is a ball bearing, the outer ring of the ball bearing is fixedly connected to the swirl cap connection seat 8, and the inner ring is connected to the nozzle 3 through the pipe 5 ( Figure 3 The inner ring of the bearing in Figure a is represented by a thick line); Figure 3 As shown in Figure b, the space between the outer ring and the inner ring on the bottom surface of the ball bearing is sealed, and one end of the pipe is connected to the outer ring ( Figure 3 The outer ring of the bearing in Figure b is connected (indicated by the thick line), and the other end is connected to the external fluid.

[0024] Example 2

[0025] The structure of this embodiment is the same as that of embodiment 1, except that the number of nozzles 3 is 5, and the angle between the nozzles 3 and the swirl cap body 1 is 40° (the nozzles 3 are tilted outward). This design can increase the coverage area of ​​the fire extinguishing material sprayed by the nozzles and improve the fire extinguishing efficiency.

[0026] The nozzle arrangement structure, nozzle mounting plate and printing device provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification is only an implementation method of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention. It should not be understood as a limitation of the present invention.
