DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0032] It can be understood that the terms "first", "second", and the like used herein can be used to describe various elements, but unless specifically stated, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0033] As Figure 1 , Figure 4 and Figure 5 shown, in one embodiment, a hot air disturbance soot blowing system is proposed, which comprises:

[0034] The main cylinder 1 comprises a mounting pipe 101 arranged on the main cylinder 1.

[0035] The disturbance mechanism 2 comprises a plurality of disturbance rotating cylinders 202 mounted inside the mounting pipe 101, and four disturbance air nozzles 201 are rotatably arranged on the surface of the disturbance rotating cylinders 202.

[0036] The swing mechanism 3 is used to drive the disturbance air nozzles 201 to swing back and forth.

[0037] The rotating mechanism 4 is used to drive the disturbance rotating cylinders 202 to rotate.

[0038] The air jet mechanism 5 is used to jet hot air through the disturbance air nozzles 201.

[0039] When the system performs internal air flow disturbance operation, the swing mechanism 3 and the rotating mechanism 4 are driven to move synchronously by the air jet mechanism 5, as shown in Figure 5 The movement of the swing mechanism 3 drives the disturbance air nozzles 201 to swing back and forth, and hot air is jetted from the outlets of the disturbance air nozzles 201 by the air jet mechanism 5, so as to disturb the dust inside the mounting pipe 101, so that the deposited dust is lifted again in the mounting pipe 101 and is brought into the dust collection place by the air flow of the mounting pipe 101, thereby avoiding the safety hazard caused by excessive deposition of internal dust, as shown in Figure 4 and Figure 5 The rotating mechanism 4 is driven to move by the air jet mechanism 5, and the movement of the rotating mechanism 4 drives the disturbance rotating cylinders 202 to rotate, thereby driving the four disturbance air nozzles 201 to rotate. The rotation of the disturbance air nozzles 201 causes the tangential force of the air flow jetted from the disturbance air nozzles 201, so that the dust is more easily lifted from the mounting pipe 101 by the action of two forces, thereby increasing the sufficiency of disturbance and reducing the deposition amount of dust. At the same time, since the disturbance air nozzles 201 on the adjacent disturbance rotating cylinders 202 are in the process of swinging, the air flow will exist in the contact surface when jetted, and the mutual impact between the air flows generates turbulence, thereby making the large particle dust rub in advance, thereby increasing the fineness of the particles, so that the dust is more easily disturbed into the air flow.

[0040] As Figure 4 , Figure 8 and Figure 9As shown, as a preferred embodiment of the present invention, the swing mechanism 3 includes a movable rack 301 meshing with the disturbance air nozzle 201, one end of the movable rack 301 is fixedly mounted on the linkage cylinder 302, the surface of the linkage cylinder 302 is slidably connected to the contact rod 303, the end of the contact rod 303 away from the linkage cylinder 302 is in contact with the surface of the rotating cam 304, and a compression spring 305 is fixedly mounted on the surface of the linkage cylinder 302.

[0041] In practical application, the embodiment of the present invention is as follows: Figure 4 As shown, at this time, the cam 304 is driven to rotate by the action of the jet mechanism 5, as shown in FIG. Figure 9 As shown, from Figure 9 When viewed from the front, the rotation of the rotating cam 304 drives the contact rod 303 to reciprocate up and down, and then drives the moving rack 301 to reciprocate up and down through the linkage cylinder 302. At the same time, the reciprocating motion of the moving rack 301 drives the disturbance air nozzle 201 to continuously swing back and forth through the meshing action with the disturbance air nozzle 201, thereby performing a range of jet disturbance through the disturbance air nozzle 201, thereby increasing the sufficient disturbance of dust.

[0042] like Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the rotating mechanism 4 includes a connecting gear cylinder 401 fixedly connected to the surface of the disturbance drum 202, the connecting gear cylinder 401 is engaged with the rotating gear 402, and a bevel gear set 403 is fixedly installed on the end of the rotating gear 402 away from the connecting gear cylinder 401, and the end of the compression spring 305 away from the linkage cylinder 302 is connected to the connecting gear cylinder 401.

[0043] In practical application, the embodiment of the present invention is as follows: Figure 4 As shown, under the action of the jet mechanism 5, the bevel gear set 403 is driven to rotate, as shown in FIG. Figure 5 As shown, the rotation of the bevel gear set 403 drives the connecting gear cylinder 401 to rotate through the rotating gear 402. At this time, the rotation of the connecting gear cylinder 401 drives the disturbance drum 202 to rotate, and then drives the disturbance air nozzle 201 to rotate synchronously. The rotation of the disturbance air nozzle 201 generates a tangential force on the dust deposited on the installation pipe 101 during the air jetting process, so that the dust cannot effectively adhere to the inner wall of the installation pipe 101. At the same time, due to the difference between the rotation speed of the disturbance drum 202 and the swinging speed of the disturbance air nozzle 201, the range swept by the disturbance air nozzle 201 is annular, which fully disturbs the dust deposited on the inner wall of the installation pipe 101.

[0044] like Figure 2 、 Figure 3 and Figure 6As shown, as another preferred embodiment of the present invention, the jet mechanism 5 includes a jet channel 501 opened inside the disturbance drum 202, the jet channel 501, the main channel 502 and the delivery air channel 505 are connected in sequence, the main channel 502 is opened inside the branch pipe 503, the surface of the branch pipe 503 is rotatably connected to the disturbance drum 202, the surface of the branch pipe 503 is rotatably connected to the connecting gear cylinder 401, the surface of the branch pipe 503 is rotatably connected to the linkage cylinder 302, and the contact rod 303 runs through the branch pipe 503. Tube 503 is slidably connected to the branch pipe 503, the branch pipe 503 is fixedly installed on the delivery pipe 504, the delivery air channel 505 is opened inside the delivery pipe 504, and the delivery air channel 505 is connected to the inside of the diversion pipe 506, the three delivery pipes 504 are all fixedly installed on the diversion pipe 506, and the main pipe 507 is fixedly installed on the surface of the diversion pipe 506, the main pipe 507 passes through the installation pipe 101 and is fixedly connected to the installation pipe 101, and the inside of the diversion pipe 506 is connected to the inside of the main pipe 507.

[0045] In practical application of the embodiment of the present invention, when the dust deposited on the inner wall of the installation pipe 101 is disturbed, as shown in FIG. Figure 6 As shown, at this time, the hot air flow enters the branch pipe 506 through the main pipe 507, as shown in FIG. Figure 3 As shown, the dust then enters the inside of the branch pipe 503 from the conveying pipe 504, and is then ejected from the disturbance air nozzle 201 through the jet channel 501 opened inside the disturbance drum 202. The adjacent branch pipes 503 are circumscribed by the circular ring disturbed by the disturbance air nozzle 201, thereby achieving the purpose of automatically and fully disturbing the dust to flow.

[0046] like Figure 4 As shown, as another preferred embodiment of the present invention, the system also includes a driving mechanism 6, which includes a driving fan blade 601 that passes through the branch pipe 503 and is rotatably connected to the branch pipe 503, and a fan blade is provided on the driving fan blade 601. A rotating cam 304 is fixedly installed on the surface of the driving fan blade 601, and a bevel gear set 403 is also fixedly installed on the surface of the driving fan blade 601.

[0047] In practical application of the embodiment of the present invention, when performing dust disturbance operation, such as Figure 4 As shown, the airflow inside the branch pipe 503 drives the driving blade 601 to rotate, and the rotation of the driving blade 601 drives the rotating cam 304 and the bevel gear set 403 to rotate synchronously, thereby driving the disturbance air nozzle 201 to swing and rotate synchronously, thereby achieving the purpose of fully disturbing the dust.

[0048] like Figure 7As shown, as another preferred embodiment of the present invention, the soot blowing system also includes a dustproof mechanism 7, which includes a dustproof cylinder 701 fixedly mounted on the surface of the branch pipe 503, and the connecting gear cylinder 401 is rotatably connected to the inner wall of the dustproof cylinder 701.

[0049] In practical application, the embodiment of the present invention is as follows: Figure 7 As shown, the dustproof cylinder 701 provided on the branch pipe 503 effectively protects the internal transmission mechanism, preventing dust from entering the transmission mechanism, increasing the friction of the transmission mechanism, and thus reducing the service life of the mechanism.

[0050] like Figure 9 As shown, as another preferred embodiment of the present invention, a rolling ball is provided at the contact end of the contact rod 303 and the rotating cam 304 .

[0051] In practical application, the embodiment of the present invention is as follows: Figure 9 As shown, by the rolling ball provided on the contact rod 303, sliding friction is converted into rolling friction, thereby increasing the service life of the device.
