[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is a reference to the appendix. Figures 1 to 5 A desulfurization spray gun 100 that is easy to install is described in detail in an embodiment of the present invention.

[0030] The easy-to-install desulfurization spray gun 100 of this invention includes a spray gun 1, a connecting pipe 2, and an installation assembly 3. One end of the spray gun 1 is provided with a spray nozzle. The connecting pipe 2 includes a pipe body 21 and an interface pipe 22. One end of the pipe body 21 is connected to the other end of the spray gun 1. The pipe body 21 and the interface pipe 22 are provided on the pipe body 21. The interface pipe 22 is connected to the spray gun 1 through the pipe body 21 and is used to connect to the desulfurizing agent delivery pipeline (not shown in the figure). The mounting assembly 3 includes a mounting ring 31 and a fastener 32. The mounting ring 31 is located at the other end of the tube body 21. The end of the mounting ring 31 facing away from the tube body 21 is provided with a receiving groove 311, which extends axially along the mounting ring 31. A limiting groove 312 is provided on the inner wall of the receiving groove 311. The fastener 32 includes a fixing plate assembly 321, a limiting rod 322, and a limiting ball 323. The fixing plate assembly 321 is used to be placed in the area to be installed. One end of the limiting rod 322 is connected to the fixing plate assembly 321, and the other end of the limiting rod 322 is provided with a limiting ball 323. The other end of the limiting rod 322 is detachably connected to the mounting ring 31 and has an installation position and a detached position. In the installation position, the limiting ball 323 is located in the limiting groove 312, and the mounting ring 31 is adjacent to or abuts against the fixing plate assembly 321. In the detached position, both the limiting ball 323 and the limiting rod 322 are detached from the mounting ring 31.

[0031] In this embodiment of the invention, the desulfurization spray gun 100 requires the fixing member 32 to be pre-installed in the installation area. For example, the fixing plate assembly 321 is installed in the installation area by welding or bolting. For multiple different desulfurization spray guns 100, their spray gun 1 models can be the same or different, and their mounting components 3 can use the same specifications. Multiple desulfurization spray guns 100 with the same mounting component 3 specifications can share a fixing member 32. Therefore, a fixing member 32 that has been installed in the installation area of ​​the desulfurization spray gun 100 can be matched with different spray guns 1 and can be used to install different desulfurization spray guns 100. See also... Figure 2 , Figure 2 The vertical direction of the mounting ring 31 is parallel to the axial direction of the mounting ring 31. When installing the spray gun 1, the spray gun 1 is moved so that the receiving groove 311 of the mounting ring 31 is aligned with the limiting rod 322. The mounting ring 31 is then moved towards the fixing plate group 321, that is, the mounting ring 31 is moved downwards, so that the limiting rod 322 and the limiting ball 323 are moved into the receiving groove 311. Then, the mounting ring 31 is moved further towards the fixing plate group 321, so that the limiting ball 323 is moved into the limiting groove 312. Then, the limiting rod 322 is moved to the installation position, completing the connection between the mounting ring 31 and the fixing member 32. When it is necessary to remove the desulfurization spray gun 100, move the spray gun 1 away from the fixed plate group 321, that is, move the mounting ring 31 upward, so that the limiting ball 323 disengages from the limiting groove 312, and then the limiting ball 323 and the limiting rod 322 disengage from the receiving groove 311, thereby realizing the disengagement of the mounting ring 31 and the fixing part 32, that is, realizing the disassembly of the spray gun 1.

[0032] The desulfurization spray gun 100 of this embodiment uses an installation component 3 to detachably connect the spray gun 1 and the area to be installed. On the one hand, the fixing component 32 can be used with different mounting rings of the spray gun 1, resulting in minimal structural changes and easy manufacturing for the spray gun 1. On the other hand, the cooperation of the limiting ball 323 and the limiting groove 312 limits and fixes the mounting ring 31 in the circumferential and axial directions, thereby realizing the installation of the spray gun 1. The installation process is simple and easy to operate. Therefore, the installation process of the desulfurization spray gun 100 of this embodiment is simple and can save the installation time of the spray gun 1.

[0033] In some embodiments, such as Figure 2 As shown, the fixing member 32 further includes a first pushing block 324 and a second pushing block 325. Both the first pushing block 324 and the second pushing block 325 are located at the other end of the limiting rod 322, respectively positioned on both sides of the limiting ball 323 along the axial direction of the mounting ring 31. The first pushing block 324 and the second pushing block 325 form a protective barrier for the limiting ball 323 along the axial direction of the mounting ring 31. When the limiting ball 323 and the receiving groove 311 are connected, this prevents the limiting ball 323 from directly contacting or even colliding with the mounting ring 31, and prevents the limiting ball 323 from directly colliding with the bottom wall of the receiving groove 311. This avoids excessive wear of the limiting ball 323, ensures the reliability of the fixed fit between the limiting ball 323 and the limiting groove 312, and thus ensures the reliability of the spray gun 1 installation.

[0034] Specifically, both the first pushing block 324 and the second pushing block 325 are frustoconical in shape, and both have a large-diameter end and a small-diameter end. The large-diameter end of the first pushing block 324 is adjacent to the limiting ball 323, and the small-diameter end is away from the limiting ball 323. The conical surface of the first pushing block 324 provides a guiding function when the first pushing block 324 enters the receiving groove 311, improving the convenience and speed of the first pushing block 324 and the limiting rod 322 entering the receiving groove 311. The large-diameter end of the second pushing block 325 is away from the limiting ball 323, and the small-diameter end is adjacent to the limiting ball 323. The diameter of the small-diameter end of the first push block 324 and the small-diameter end of the second push block 325 are equal to the diameter of the limiting rod 322. In the axial direction of the limiting rod 322 (which is also the axial direction of the mounting ring 31), the limiting ball 323 protrudes from the large-diameter end of the first push block 324 and the large-diameter end of the second push block 325 to cooperate with the limiting groove 312.

[0035] In some embodiments, the receiving groove 311 is an annular groove, and the first pushing block 324 is located on the side of the limiting ball 323 away from the fixing plate assembly 321. In this installation position, the first pushing block 324 abuts against the bottom wall surface of the receiving groove 311. Figure 2As shown, the first pushing block 324 is located above the limiting ball 323, and the bottom wall of the receiving groove 311 is the wall of the bottom of the receiving groove 311. The receiving groove 311 is an annular groove, which facilitates the entry of the limiting rod 322 into the receiving groove 311, improves the convenience of the docking between the mounting ring 31 and the fixing member 32, and further improves the convenience of the installation process of the spray gun 1. When the limiting rod 322 moves to the bottom wall of the receiving groove 311 where the first pushing block 324 abuts, the operator can determine that the limiting rod 322 has been installed in place in its axial direction. Then, the limiting groove 312 can be made to engage with the limiting ball 323 by rotating the mounting ring 31. When the operator feels an increase in rotational resistance while rotating the mounting ring 31, it means that the limiting ball 323 has engaged with the limiting groove 312, and then the rotation of the mounting ring 31 can be stopped.

[0036] Furthermore, there are multiple limiting rods 322, which are arranged at equal intervals. Correspondingly, each limiting rod 322 is provided with a limiting ball 323, thereby improving the connection strength between the mounting ring 31 and the fixing member 32 and improving the installation stability of the spray gun 1.

[0037] In some embodiments, such as Figure 2 As shown, the fixing plate assembly 321 includes a washer 3211, an elastic element 3212, and a buffer plate 3213. The washer 3211 is connected to one end of the limiting rod 322. The buffer plate 3213 is placed in the area to be installed. One end of the elastic element 3212 is located on the side of the washer 3211 away from the limiting rod 322, and the other end of the elastic element 3212 is connected to the buffer plate 3213. Therefore, when the fixing element 32 is pre-installed in the area to be installed, the buffer plate 3213 can be installed in the area by welding or bolting. An elastic element 3212 is provided between the washer ring 3211 and the buffer plate 3213. The elastic element 3212 can absorb vibration. When the mounting ring 31 is moved towards the fixing member 32, after the limiting rod 322 and the limiting ball 323 are installed in place in the axial direction of the mounting ring 31, the mounting ring 31 tends to continue moving due to inertia or large force applied by personnel. The gap between the washer ring 3211 and the buffer plate 3213 provides space for the continued movement of the mounting ring 31. The elastic element 3212 can also absorb part of the force through its own deformation, thereby buffering the movement of the mounting ring 31 and preventing the mounting ring 31 from directly hitting the installation area and causing damage.

[0038] Furthermore, the elastic element 3212 is a spring. Springs have a simple structure and low cost. When compressed, the spring absorbs vibration through its expansion and contraction. The mounting assembly 3 further includes a telescopic rod, which connects the washer 3211 and the buffer plate 3213. The spring is sleeved on the telescopic rod. The telescopic rod guides the expansion and contraction of the spring, preventing skewing during elastic expansion and contraction.

[0039] like Figure 4and Figure 5 As shown, the desulfurization spray gun 100 of this embodiment further includes a sealing element 4, which includes a first sealing ring 41 and a sealing gasket 42. The first sealing ring 41 is disposed inside the interface pipe 22, and the first sealing ring 41 has an installation groove 411 for connecting with the desulfurizing agent delivery pipeline. The sealing gasket 42 is disposed inside the installation groove 411 and is used to abut against the desulfurizing agent delivery pipeline. The desulfurizing agent delivery pipeline is installed in the installation groove 411 of the interface pipe 22. The sealing gasket 42 can increase the sealing performance of the desulfurizing agent delivery pipeline and the installation groove 411, ensuring the sealing of the connection between the desulfurizing agent delivery pipeline and the interface pipe 22.

[0040] In some embodiments, the seal 4 further includes a second sealing ring 43 and a sealing ring 44. The second sealing ring 43 is disposed inside the first sealing ring 41. The outer surface of the second sealing ring 43 and the inner surface of the interface pipe 22 form a space for installing the desulfurizing agent delivery pipeline. The sealing ring 44 is sleeved on the second sealing ring 43 to abut against the desulfurizing agent delivery pipeline. The sealing ring 44 forms a seal on the inner side of the desulfurizing agent delivery pipeline and the outer side of the second sealing ring 43, thereby further improving the sealing performance of the desulfurizing agent delivery pipeline and the interface pipe 22.

[0041] The sealing ring 44 and the sealing gasket 42 form a compression and seal on the inner side and end of the desulfurizing agent delivery pipeline. After connecting the desulfurizing agent delivery pipeline and the interface pipe, there is no need to seal them again, which can further simplify the installation process of the desulfurization spray gun 100 in this embodiment of the invention and improve the convenience of installation.

[0042] In some embodiments, the seal 4 further includes multiple limiting strips 45, which are distributed circumferentially along the second sealing ring 43. Both ends of each limiting strip 45 are connected to the second sealing ring 43. A sealing ring 44 is disposed between the limiting strips 45 and the second sealing ring 43. The sealing ring 44 is mounted on the second sealing ring 43 via the multiple limiting strips 45, which simplifies the installation and ensures a secure connection between the sealing ring 44 and the second sealing ring 43.

[0043] In some embodiments, the desulfurization spray gun 100 further includes a sleeve 5, which is sleeved on the spray gun 1 and has anti-slip grooves. The anti-slip grooves extend along the axial direction of the spray gun 1, and there are multiple anti-slip grooves. The anti-slip grooves facilitate personnel to move the spray gun 1 by holding the sleeve 5.
