[0022] See also Figure 1-4 A flue evaporator soot blowing mechanism in this embodiment includes a flue bin 1, a support rod 3 located on the inner wall of the flue bin 1, and a soot blowing structure located on the support rod 3.

[0023] In the present application, the soot blowing structure moves on the support rod 3, so that the soot blowing can be performed on the single-layer filter structure in the cross section of the flue bin 1.

[0024] In this embodiment, the soot blowing structure includes a hook 5 slidably connected to the support rod 3 and a distributor 4 fixedly connected to the hook 5 , wherein a nozzle 6 is connected below the distributor 4 .

[0025] Preferably, there are a plurality of nozzles 6 , and the plurality of nozzles 6 are continuously arranged below the distributor 4 .

[0026] In a specific implementation, the soot blowing of the flue evaporator can be achieved by passing the gas source into the distributor 4 and blowing from a plurality of nozzles 6 .

[0027] It should be noted that there are two hooks 5 on the distributor 4 , and the two hooks 5 are symmetrically located at both ends of the distributor 4 . The two hooks 5 can form an embracing structure, so that the distributor 4 can be stably set on the support rod 3 .

[0028] In this embodiment, there are several distributors 4, which are connected by connecting pipes 7, so that the distributors 4 can be arranged in an array in the flue bin 1 for soot blowing, thereby improving the concentration of soot blowing.

[0029] It can be understood that a gas source pipeline 17 is fixed to the outside of the flue bin 1, and one end of the gas source pipeline 17 is directly connected to an air supply source, and the selected air supply source can be an air pump.

[0030] In this embodiment, a support frame 2 is fixedly installed on the outside of the flue bin 1, and a traction structure is provided on the support frame 2 for controlling the movement of the distributor 4. The traction structure includes a push rod 11 fixedly installed on the support frame 2 and a gear 15 for pulling the push rod 11, wherein the push rod 11 is fixedly connected to the distributor 4, and the movement of the push rod 11 can drive the distributor 4 to move relative to the support rod 3.

[0031] It should be noted that a stabilizing frame 8 is fixedly mounted on the supporting frame 2 , a mounting plate 9 is fixedly mounted on the stabilizing frame 8 , a guide sleeve 10 is fixedly mounted on the mounting plate 9 , and a push rod 11 is slidably connected to the guide sleeve 10 .

[0032] With such a design, the moving track of the push rod 11 is guided by the guide sleeve 10 on the mounting plate 9, so that the moving stability of the push rod 11 can be improved.

[0033] In this embodiment, an electric push rod 13 is fixedly mounted on the mounting plate 9, and a mounting frame 14 is fixedly mounted on the power end of the electric push rod 13, and the mounting frame 14 is rotatably connected to the gear 15;

[0034] It is additionally explained that a tooth groove 12 is provided on the outer wall of the push rod 11 , and the gear 15 is tooth-engaged in the tooth groove 12 . The gear 15 rotates to enable the push rod 11 to move relative to the guide sleeve 10 .

[0035] In this embodiment, a rack 16 is fixedly mounted on the mounting plate 9, and the rack 16 is meshed with the gear 15 at the same time. The rack 16 is located on the side of the gear 15 away from the push rod 11, so that the gear 15 can rotate when it moves relative to the rack 16.

[0036] In the present application, support rods 3 and distributors 4 are evenly arranged in the flue bin 1, and the distributor 4 is connected to the air circuit, so that the nozzle 6 on the distributor 4 can evenly blow soot in the flue bin 1, and the push rod 11 is arranged to cooperate with the gear 15 to obtain twice the propulsion space, which can achieve uniform coverage of the flue bin 1, improve the uniformity of soot blowing distribution, and improve the practicability of the device.

[0037] The working principle of the above embodiment is:

[0038] When soot blowing is required, the electric push rod 13 is controlled, and the electric push rod 13 drives the mounting frame 14 on the power end to move relative to the mounting plate 9. At this time, the gear 15 located at the end of the mounting frame 14 moves relative to the rack 16, and the gear 15 rotates under the tooth meshing. The tooth meshing of the gear 15 can push the push rod 11 to slide relative to the guide sleeve 10. At the same time, the gear 15 rotates, so that the push rod 11 obtains a larger propulsion range, thereby being able to pull the distributor 4 to slide relative to the support rod 3 to evenly blow soot in the flue bin 1.
