[0015] Figure 2 Shown as Figure 1 An enlarged schematic view of area A in Detailed Embodiments

[0016] To further illustrate the embodiments, the present utility model provides drawings. These drawings are a part of the disclosure of the present utility model, which are mainly used to illustrate the embodiments and can be used to explain the operating principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] Now, the present utility model will be further described in conjunction with the drawings and specific embodiments.

[0018] Refer to Figure 1As shown in the figure, this embodiment provides an anti-blocking device for a flue gas treatment settling chamber (hereinafter referred to as the anti-blocking device). The anti-blocking device includes a settling chamber body 1. The bottom of the settling chamber body 1 has an ash outlet 11. It also includes a rotating mechanism 2 for forming a turbulent flow. The rotating mechanism 2 includes a driver 21, a bevel gear assembly 22, and a rotating fan blade assembly 23. The rotating part of the rotating fan blade assembly 23 extends into the ash outlet 11. The driver 21 drives the rotating part of the rotating fan blade assembly 23 to rotate through the bevel gear assembly 22 to form a turbulent flow setting, thereby driving the dust at the ash outlet 11 to move disorderly.

[0019] In this embodiment, the cross-sectional shape of the settling chamber body 1 is conical to facilitate the dust in the settling chamber body 1 to concentrate and fall toward the ash outlet 11.

[0020] The driver 21 drives the bevel gear assembly 22 to make corresponding rotations, and then drives the rotation of the rotating part of the rotating fan blade assembly 23 to form a turbulent flow in the ash outlet 11 of the settling chamber body 1.

[0021] By extending the rotating part of the rotating fan blade assembly 23 into the ash outlet 11 of the settling chamber body 1 and rotating it, a turbulent flow is formed in the ash outlet 11 of the settling chamber body 1, driving the dust at the ash outlet 11 to move disorderly. Thus, it is realized that the dust is not easy to accumulate and compact at the ash outlet 11, reducing the probability of blockage. Moreover, the structure of the anti-blocking device is compact, simple, and efficient.

[0022] In another preferred embodiment, the driver 21 is a driving motor.

[0023] More specifically, as Figure 2 shown, the bevel gear assembly 22 includes a first bevel gear 221 and a second bevel gear 222 that are engaged with each other. A support 3 is fixed outside the settling chamber body 1. The driving motor and the rotating fan blade assembly 23 are both fixed on the support 3. The driving shaft of the driving motor is drivingly connected to the first bevel gear 221, and the rotating shaft part of the rotating fan blade assembly 23 is connected to the second bevel gear 222.

[0024] During specific implementation, the rotating fan blade assembly 23 includes a rotating fan blade 231 and a rotating shaft 232. The rotating fan blade 231 is fixed on the rotating shaft 232. A first support frame 31 is fixed on the side of the support 3 close to the ash outlet 11. One end of the rotating shaft 232 facing away from the rotating fan blade 231 rotatably passes through the first support frame 31 and is fixed together with the second bevel gear 222. The rotating fan blade 231 is the rotating part, and the rotating shaft 232 is the rotating shaft part.

[0025] A second support frame 32 is fixedly attached to the bottom of the support 3. A connecting shaft 4 is disposed between the drive shaft of the drive motor and the first bevel gear 221. The connecting shaft 4 is rotatably passed through the second support frame 32. One end of the connecting shaft 4 is fixed to the drive shaft of the drive motor, and the other end is fixed to the first bevel gear 221.

[0026] The drive shaft of the driver 21 drives the connecting shaft 4 to rotate, thereby driving the first bevel gear 221 to rotate accordingly. Then, through the meshing connection relationship between the first bevel gear 221 and the second bevel gear 222, the second bevel gear 222 is driven to rotate synchronously with the rotating shaft 232, thereby driving the rotating fan blade 231 to rotate in the ash outlet 11 and agitating the flue gas and the dust in the flue gas in the ash outlet 11 to jointly form a turbulent flow, so as to drive the dust at the ash outlet 11 to move disorderly, thereby preventing the dust from easily accumulating and compacting at the ash outlet 11 and reducing the probability of blockage.

[0027] In addition, by disposing the drive motor on the support 3 outside the sedimentation chamber body 1, the working environment of the drive motor is avoided from the harsh environments such as high temperature and high humidity inside the sedimentation chamber body 1, so as to ensure the reliability of the rotating fan blade assembly 23.

[0028] In another preferred embodiment, a maintenance opening 12 for maintenance as shown in Figure 1 is provided on the side wall of the sedimentation chamber body 1, so as to facilitate maintenance personnel to enter the sedimentation chamber body 1 for maintenance after opening the maintenance opening 12.

[0029] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
