[0025] The following is combined with Figure 1-6The technical solution of the present invention is described in detail with reference to the preferred embodiment, wherein: 1. fan; 2. bracket; 3. slide rod; 4. slider; 5. hanger plate; 51. top plate; 52. side plate; 53. bottom plate; 54. hook hole; 6. hook; 7. fixed upper plate; 8. fixed lower plate; 9. wiring device; 10. support; 11. fan outlet; 12. air filter; 13. solenoid valve assembly; 14. nozzle; 15. furnace body.

[0026] like Figure 1-6 As shown, the present invention discloses a mobile fan device for a boiler, which includes a fan 1, a support portion, and a sliding assembly. The support portion is fixed to the bracket 2 of the boiler, and is used to bear the weight of the fan and limit the movement trajectory of the fan. The fan is fixed to the sliding assembly, and the sliding assembly can move back and forth along the support portion, so the fan can move back and forth along the support portion along with the sliding assembly. Therefore, when the boiler needs to be inspected and repaired, only one person is needed to move the fan, and there is no need for multiple people to cooperate to dismantle the fan at the same time, which greatly saves manpower, material resources and time.

[0027] The fan movement process may be as follows: the fan 1 includes one or more interface mounting portions. When the fan is in normal operation, the sliding assembly is placed in a first position on the support portion, and the fan interface mounting portions are aligned and fixed with the interface mounting portions of other devices in the boiler. When the boiler requires inspection and maintenance, the fan interface mounting portions are detached from the interface mounting portions of other devices in the boiler, and the sliding assembly is moved from the first position along the support portion to drive the fan to move together.

[0028] It should be noted that the support portion and sliding assembly can be implemented in a variety of ways. For example, the support portion can be one or more slide bars, on which the sliding assembly suspends the fan; or the support portion can be one or more slide rails, along which the sliding assembly slides. Of course, the support portion and sliding assembly can also be implemented in other ways, as long as their functions are the same as those of the present invention, and they all fall within the scope of protection of the present invention.

[0029] like Figure 1-3As shown, as a preferred embodiment of the mobile fan device described in the present invention, the support portion is a slide bar 3, and the sliding assembly includes a slider 4, a hanger plate 5 fixedly mounted on the slider 4, a plurality of hooks 6 suspended from the hanger plate 5, and a retaining portion provided on the plurality of hooks 6. The slide bar 3 is fixed to the bracket 2 of the boiler, passes through the slider 4, and the slider 4 can move back and forth along the slide bar 3. The hanger plate 5 is fixedly mounted on the slider 4, and a plurality of hooks 6 are hung on the hanger plate 5. The plurality of hooks are provided with retaining portions for securing the fan to the hooks and can move with the movement of the hooks. Therefore, when the slider moves along the slide bar, the slider 4 drives the hanger plate 5 to move, the hanger plate 5 drives the hooks 6 to move, and the hooks 6 drive the retaining portion and the fan 1 to move, so that the fan 1 can move back and forth along the slide bar with the slider. Of course, force can also be applied to the hooks, so that the hooks drive the entire slider assembly and the fan to move along the slide bar.

[0030] As a preferred embodiment of the above preferred solution, Figure 2 and Figure 5 As shown, the fan 1 includes a fan outlet 11. When the slider 4 is placed in the first position of the support rod 3 (the first position is the position of the slider when the fan is in normal operation), the fan outlet 11 is aligned with the inlet of the boiler furnace 15 and is fixed. The air filter 12 sends filtered air into the nozzle, and the solenoid valve assembly 13 sends gas into the nozzle 14. The nozzle 14 sends the mixed air and gas into the fan. The fan mixes the air and gas again and then sends the mixed air and gas into the furnace 15 through the fan outlet 11 for combustion. When the boiler needs to be inspected and maintained, the fan outlet 11 is detached from the inlet of the furnace 15, and the slider is moved from the first position to move along the support portion to drive the fan to move together. Figure 3 This is the position of the sliding assembly in the boiler maintenance state. As can be seen from the figure, the fan moves to one end of the sliding rod along with the slider, and the original position of the fan is vacant, making it convenient for maintenance personnel to check and repair other parts of the boiler that were originally blocked by the fan.

[0031] As a preferred embodiment of the above preferred solution, the retaining portion provided on the hook 6 includes one or more sets of fixed upper plates 7 and fixed lower plates 8. Each set of fixed upper plates and fixed lower plates is provided on one or more hooks, and the distance between the fixed upper plates and fixed lower plates is adjustable. The fan is fixed to the hook via one or more sets of fixed upper plates and fixed lower plates. Preferably, two sets of fixed upper plates and fixed lower plates are provided, with the ends of the fan respectively embedded between the two sets of fixed upper plates and fixed lower plates.

[0032] like Figure 6As shown, as a preferred embodiment of the above-mentioned preferred scheme, the hanger plate includes a top plate 51, a bottom plate 53 and two side plates 52, and the slider 4 is embedded in the space enclosed by the top plate 51, the bottom plate 53 and the two side plates 52. The top plate is fixed on the top of the slider, and preferably the top plate is fixed to the slider by screws. The two side plates are arranged on both sides of the slider, and hook holes are respectively provided at both ends of each side plate, and the hooks are hung on the hanger plate through the hook holes. In order to prevent the two side plates from being deformed due to heavy pressure, a bottom plate is added to the bottom of the hanger plate as a reinforcement rib to increase the load-bearing capacity of the side plates. Preferably, the two ends of each side plate of the hanger plate extend out of the two ends of the bottom plate of the hanger plate, and the hook holes are provided on the extension of the side plates. In addition, when the fan moves to one end of the slide bar, as shown Figure 3 As shown, in order to prevent the fan from shaking too much and causing adverse effects, the vertical distance between the upper edge of the side plate of the hanger plate and the lower edge of the upper frame of the boiler support is preferably 1 to 5 mm.

[0033] As a preferred embodiment of the above preferred solution, a support 10 is fixedly provided on the bracket 2 of the boiler, one end of the slide rod is provided on the bracket, and the other end is provided on the support 10, which facilitates the installation of the slide rod.

[0034] like Figure 4 As shown, as a preferred embodiment of the mobile fan device described in the present invention, a wiring device 9 can be added to secure the fan wiring within the wiring device 9. The wiring device 9 moves with the movement of the fan, or the wiring device changes shape with the movement of the fan. This ensures a neat, standardized, and aesthetically pleasing wiring environment for the fan, making it easier for maintenance personnel to inspect and repair the boiler. Preferably, the wiring device 9 is in the form of an elongated strip, with one end secured to the boiler bracket 2 and the other end secured to the sliding assembly. The wiring device can bend with the movement of the sliding assembly.

[0035] The present invention also discloses a boiler, which comprises a bracket, a furnace body and the mobile fan device of the present invention.
