[0024] The present invention provides a rotatable boiler soot blower. Figure 1-6 As shown, the rotatable boiler sootblower includes: a mounting frame 1; a hollow shaft 2 rotatably mounted on the mounting frame 1; a connecting pipe 3 fixedly mounted on the mounting frame 1, the connecting pipe 3 and the hollow shaft 2 being sealed and rotatably connected, the connecting pipe 3 being used to pass steam into the hollow shaft 2; a sootblowing gun 4 fixedly mounted on the hollow shaft 2, the sootblowing gun 4 being communicated with the hollow shaft 2, the sootblowing gun 4 being used to blow soot on the heating surface of the boiler, and a plurality of exhaust ports 5 being provided on the sootblowing gun 4; a cleaning mechanism mounted on the sootblowing gun 4, the cleaning mechanism being used to clean impurities adhered to the surface of the sootblowing gun 4; a rotating mechanism arranged on the mounting frame 1 and the hollow shaft 2, the rotating mechanism being used to drive the sootblowing gun 4 to rotate; a driving mechanism mounted on the sootblowing gun 4 and the cleaning mechanism, the driving mechanism being used to drive the cleaning mechanism to rotate to clean dust adhered to the surface of the sootblowing gun 4.

[0025] In this embodiment, when sootblowing the boiler, the entire device is first installed. During installation, the sootblowing lance 4 is installed in the corresponding installation position. When sootblowing the boiler, the connecting pipe 3 and the corresponding steam pipe are connected. Steam enters the hollow shaft 2 through the connecting pipe 3 and is then blown onto the heating surface of the boiler through the sootblowing lance 4. At the same time, the controller activates the rotating mechanism to drive the hollow shaft 2 to rotate, thereby driving the sootblowing lance 4 to rotate. The rotating sootblowing lance 4 evenly blows soot on the heating surface of the boiler, thereby improving the sootblowing effect on the heating surface of the boiler.

[0026] When the sootblowing gun 4 has been used for a certain period of time and the dust adhering to the surface of the sootblowing gun 4 needs to be cleaned, the driving mechanism is started by the controller to drive the cleaning mechanism to rotate, so that the dust adhering to the surface of the sootblowing gun 4 can be cleaned. When the sootblowing gun 4 is not in use, the exhaust port 5 can be blocked by the cleaning mechanism to reduce the dust from entering the exhaust port 5. Through the entire device, the boiler can be sootblown and the dust adhering to the surface of the sootblowing gun 4 can be cleaned, thereby reducing the corrosion of the sootblowing gun 4 by dust, extending the service life of the sootblowing gun 4 and reducing the overall failure rate.

[0027] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a mounting block 6 rotatably mounted on the sootblowing gun 4; a cleaning rack 7 fixedly mounted on the mounting block 6, the cleaning rack 7 being located outside the sootblowing gun 4, the cleaning rack 7 being used to clean dust adhered to the surface of the sootblowing gun 4, and a plurality of brushes 16 being provided on the cleaning rack 7, the brushes 16 being in contact with the surface of the sootblowing gun 4.

[0028] In this embodiment, when the cleaning mechanism is used, the driving mechanism drives the mounting block 6 to rotate, thereby driving the cleaning frame 7 to rotate. Under the action of the brush 16, the dust adhering to the surface of the sootblowing gun 4 can be cleaned, thereby reducing the corrosion of the sootblowing gun 4 caused by dust, extending the service life of the sootblowing gun 4, and reducing the overall failure rate.

[0029] In a further preferred embodiment of the present utility model, the rotating mechanism includes: a driving motor 8 arranged on the mounting frame 1, a placing frame fixedly mounted on the mounting frame 1, and the placing frame and the driving motor 8 are fixedly connected; a mounting shaft 9 rotatably mounted on the mounting frame 1, and a first circular gear 10 is fixedly sleeved on the mounting shaft 9; a second circular gear 11 fixedly sleeved on the hollow shaft 2, and the second circular gear 11 is meshed with the first circular gear 10; two first pulleys 12 fixedly sleeved on the mounting shaft 9 and the output shaft of the driving motor 8, respectively, and a first belt 13 is sleeved on the two first pulleys 12.

[0030] In this embodiment, when the driving mechanism is used, the driving motor 8 is started by the controller, and under the action of the first pulley 12 and the first belt 13, the mounting shaft 9 is driven to rotate, and under the action of the second circular gear 11 and the first circular gear 10, the hollow shaft 2 is driven to rotate, and then the soot blowing gun 4 is driven to rotate to perform uniform soot blowing treatment on the boiler heating surface.

[0031] In a further preferred embodiment of the present invention, the driving mechanism includes: a servo motor 14 fixedly mounted on the sootblowing gun 4; two third circular gears 15 fixedly mounted on the output shaft of the servo motor 14 and the mounting block 6, respectively, and the two third circular gears 15 are meshed with each other.

[0032] In this embodiment, when the driving mechanism is used, the servo motor 14 is started by the controller, and the interaction of the two third circular gears 15 can drive the cleaning frame 7 on the mounting block 6 to rotate. Under the action of the brush 16, the dust adhering to the surface of the soot blowing gun 4 can be cleaned, thereby reducing the corrosion of the soot blowing gun 4 caused by dust, extending the service life of the soot blowing gun 4, and reducing the overall failure rate.

[0033] In a further preferred embodiment of the present invention, multiple exhaust ports 5 are symmetrically opened on the sootblowing gun 4, and the cleaning frame 7 includes a connecting ring 701 and two cleaning blades 702, and the two cleaning blades 702 are symmetrically fixedly mounted on the connecting ring 701, and the two cleaning blades 702 respectively correspond to the multiple exhaust ports 5, and the connecting ring 701 is fixedly connected to the mounting block 6.

[0034] In this embodiment, a seal is first formed between the connecting ring 701 and the sootblowing gun 4. When the sootblowing gun 4 is installed, the connecting ring 701 is sealed and rotated with the corresponding installation position, and the cleaning blades 702 and the exhaust port 5 are both located in the positions that need to be cleaned, so there will be no air leakage. The two cleaning blades 702 correspond to the two rows of exhaust ports 5 respectively. When the surface of the sootblowing gun 4 is cleaned, the two rotating cleaning blades 702 drive the brush 16 to rotate to clean the dust on the surface of the sootblowing gun 4. When the sootblowing gun 4 is not in use, the two cleaning blades 702 are adjusted to the outside of the two rows of exhaust ports 5 by the driving mechanism, so that the two rows of exhaust ports 5 can be blocked to reduce the dust from entering the exhaust ports 5. When sootblowing is required, the two cleaning blades 702 and the two exhaust ports 5 are staggered to avoid blocking the exhaust ports 5.

[0036] In this embodiment, when the mounting shaft 9 rotates, under the action of the second pulley 19 and the second belt 20, the fan blades 18 on the placement shaft 17 can be driven to rotate. The rotating fan blades 18 can increase the circulation of air around the drive motor 8, thereby dissipating the heat of the drive motor 8.

[0037] In a further preferred embodiment of the present invention, two avoidance openings are provided on the placement rack, and the two avoidance openings are used to avoid the first belt 13 and the second belt 20.

[0038] In this embodiment, the avoidance opening is used to allow the first belt 13 and the second belt 20 to avoid each other.

[0039] In summary, compared with related technologies, the entire device can be used to perform soot blowing on the boiler, and the dust adhering to the surface of the soot blowing gun 4 can be cleaned, thereby reducing the corrosion of the soot blowing gun 4 caused by dust, extending the service life of the soot blowing gun 4, and reducing the overall failure rate.
