[0010] Furthermore, a controller is provided on the left side of the soot blowing base. The input terminal of the controller is electrically connected to an external power source to control various electrical appliances.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This ash blowing mechanism for a waste incineration boiler has the following advantages:

[0015] Driven by the steam flow, the impeller rotates, which in turn drives the planetary gear mechanism to rotate the four soot blowing tubes. This results in a periodic change in the direction of the steam flow as it exits the soot blowing tubes. Simultaneously, the worm gear mechanism drives the gear mechanism to adjust the vertical angle of the soot blowing tubes. This makes the direction of the soot blowing flow inside the incinerator more diverse, causing the ash on the inner wall of the incinerator to change direction due to the changing soot blowing flow. As a result, the ash on the inner wall of the incinerator can be more easily removed, greatly improving the soot removal efficiency of the inner wall of the incinerator. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This embodiment provides a technical solution: a soot blowing mechanism for a waste incineration boiler, including a soot blowing seat 1, a fixed plate 5 is provided on the rear side of the soot blowing seat 1, an adjustable soot blowing chamber 2 is provided on the rear side of the fixed plate 5, and a uniformly distributed soot blowing cylinder 4 is rotatably connected to the rear end of the soot blowing chamber 2, and also includes an adjustment component 3.

[0023] Adjustment component 3 includes a fixed base 31, a rotating shaft 32, an impeller 33, a drive gear 34, and a driven gear 35. The fixed base 31 is fixedly connected to the center of the rear surface of the fixed disk 5. The rear end of the fixed base 31 is rotatably connected to the front end of the soot blowing chamber 2 via a pin. The soot blowing chamber 2 is equipped with an air chamber, and the rotating shaft 32 is rotatably connected inside the air chamber. The impeller 33 is fixedly connected to the front end of the outer surface of the rotating shaft 32, and the drive gear 34 is fixedly connected to the rear end of the outer surface of the rotating shaft 32. The front ends of the soot blowing cylinders 4 are all fixedly connected to the driven gears 35. All four driven gears 35 are meshed with the drive gears 34. The front ends of all four soot blowing cylinders 4 are connected to the air chamber. The section assembly 3 also includes an arc-shaped plate 36, a bevel gear 37, and a rotating shaft 38. The arc-shaped plates 36 are symmetrically fixedly connected to the front end of the soot blowing chamber 2 (the central axes of the two arc-shaped plates 36 are both located on the central axis of the pin). The inner surfaces of the two arc-shaped plates 36 are provided with evenly distributed bevel teeth. The rotating shaft 38 is symmetrically rotatably connected to the inside of the fixed disk 5. The rear end of the rotating shaft 38 is fixedly connected to a bevel gear 37, which meshes with the bevel teeth adjacent laterally. The front end of the fixed disk 5 is fixedly connected to a sliding cylinder 6. The outer surface of the sliding cylinder 6 is slidably connected to the inside of the soot blowing seat 1. The front end of the sliding cylinder 6 is fixedly connected to a drive chamber 9. The rotating shaft 38 extends... Inside the drive chamber 9, worm gears 10 are fixedly connected to the front ends of rotating shafts 38. A worm 11 is rotatably connected to the upper end of the drive chamber 9, and a knob is fixedly connected to the right end of the worm 11. Both worm gears 10 are meshed with the worm 11. According to the angle required for cleaning the inner wall of the incinerator boiler, the worm 11 is rotated via the knob. The rotation of the worm 11 drives the two worm gears 10 to rotate, which in turn drives the longitudinally adjacent rotating shafts 38 to rotate. The rotation of the rotating shafts 38 drives the bevel gears 37 to rotate. The rotation of the bevel gears 37 acts on the laterally adjacent bevel teeth, causing the arc-shaped plates 36 to rotate around the central axis of the pin. The rotation of the arc-shaped plates 36 causes the soot blowing chamber 2 to rotate around the central axis of the pin. The rotation of the spindle axis causes the soot blowing chamber 2 to rotate, which in turn drives the four soot blowing tubes 4 to rotate vertically, thereby adjusting the angle of the soot blowing tubes 4. When the soot blowing tubes 4 reach the required angle, the knob is stopped. Then, the steam inside the air chamber drives the impeller 33 to rotate. The rotation of the impeller 33 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the drive gear 34 to rotate. The rotation of the drive gear 34 drives the four driven gears 35 to rotate. The rotation of the driven gears 35 drives the adjacent soot blowing tubes 4 to rotate. The rotation of the soot blowing tubes 4 realizes the automatic change of the direction of steam flow, which makes the ash on the inner wall of the incinerator easier to fall off due to the change in the direction of force, thus improving the ash removal efficiency of the inner wall of the incinerator.

[0024] The following configuration is provided: A controller 16 is located on the left side of the soot blowing base 1, and the input terminal of the controller 16 is electrically connected to an external power source. A working base 8 is fixedly connected to the front end of the soot blowing base 1. The outer surface of the sliding cylinder 6 is slidably connected to the interior of the working base 8. A guide rod 13 is fixedly connected to the left end of the front surface of the fixed plate 5, and the outer surface of the guide rod 13 is slidably connected to the interior of the soot blowing base 1 and the working base 8. An electric push rod 12 is located at the lower end of the working base 8. A support plate 7 is fixedly connected to the lower end of the outer surface of the drive chamber 9, and the rear end of the support plate 7 is fixedly connected to the telescopic end of the electric push rod 12. The input terminal of 12 is electrically connected to the output terminal of the controller 16. The controller 16 enables the operation of the electric push rod 12. The extension and retraction of the electric push rod 12 drives the drive chamber 9 to move backward through the support plate 7. The backward movement of the drive chamber 9 drives the sliding cylinder 6 to slide. At the same time, the guide rod 13 slides between the soot blowing seat 1 and the working seat 8, providing guidance and limiting for the sliding of the sliding cylinder 6. The backward movement of the sliding cylinder 6 drives the fixed plate 5 to move backward. The backward movement of the fixed plate 5 drives the soot blowing chamber 2 to move backward. The backward movement of the soot blowing chamber 2 drives the four soot blowing cylinders 4 to move backward, thereby achieving all-round cleaning of the ash accumulation on the inner wall of the incineration boiler.

[0025] Wherein: an air pipe 14 is provided at the upper end of the soot blowing chamber 2. The air pipe 14 is a flexible pipe that extends to the front side of the soot blowing seat 1. The outer surface of the air pipe 14 is slidably connected to the inside of the soot blowing seat 1. The rear end of the air pipe 14 is connected to the air chamber, and the front end of the air pipe 14 is connected to the air outlet of the external steam equipment. The input end of the external steam equipment is electrically connected to the output end of the controller 16. The external steam equipment is operated by the controller 16, and the external steam equipment pumps steam into the interior of the air chamber through the air pipe 14.

[0026] Among them, a corrugated tube 15 is fixedly connected between the fixed plate 5 and the soot blowing chamber 2, and the soot blowing seat 1 has evenly distributed mounting holes inside.

[0027] The working principle of the soot blowing mechanism for a waste incineration boiler provided by this utility model is as follows: During operation, the operator first securely connects the mounting hole inside the soot blowing seat 1 to the threaded hole of the incineration boiler using bolts, thus achieving stable installation of the soot blowing mechanism. Then, based on the required angle for cleaning the inner wall of the incineration boiler, the operator rotates the worm gear 11 via a knob. The rotation of the worm gear 11 drives the two worm wheels 10 to rotate, which in turn drives the longitudinally adjacent rotating shafts 38 to rotate. The rotation of the rotating shafts 38 drives the bevel gears 37 to rotate, which in turn acts on the laterally adjacent bevel teeth, causing the arc-shaped plates 36 to rotate around the central axis of the pin shaft. The rotation of the arc-shaped plates 36 causes the soot blowing chamber 2 to rotate around the central axis of the pin shaft. The rotation of the soot blowing chamber 2 drives the four soot blowing cylinders 4 to rotate vertically, thereby adjusting the angle of the soot blowing cylinders 4. When the soot blowing cylinders 4 reach the required angle, the operator stops rotating the knob. Then, the external steam equipment is activated via the controller 16, which transmits steam through the gas pipe 14. Steam is pumped into the air chamber, and the steam inside the air chamber drives the impeller 33 to rotate. The rotation of the impeller 33 drives the shaft 32 to rotate, which in turn drives the drive gear 34 to rotate. The drive gear 34 drives the four driven gears 35 to rotate, and the rotation of the driven gears 35 drives the adjacent soot blowing cylinders 4 to rotate. The rotation of the soot blowing cylinders 4 realizes the automatic change of the direction of steam flow, which makes the ash on the inner wall of the incinerator easier to fall off due to the change of force direction, thus improving the ash removal efficiency of the inner wall of the incinerator. At the same time, the controller 16 realizes the operation of the electric push rod 12. The retraction of the extension end of the electric push rod 12 drives the drive chamber 9 to move backward through the support plate 7. The backward movement of the drive chamber 9 drives the sliding cylinder 6 to slide. At the same time, the guide rod 13 slides between the soot blowing seat 1 and the working seat 8, providing guidance and limiting for the sliding cylinder 6. The backward movement of the sliding cylinder 6 drives the fixed plate 5 to move backward, which drives the soot blowing chamber 2 to move backward, and the backward movement of the soot blowing chamber 2 drives the four soot blowing cylinders 4 to move backward, thus realizing the all-round cleaning of the ash on the inner wall of the incinerator.

[0028] It is worth noting that the controller 16 disclosed in the above embodiments controls the operation of the electric push rod 12 and the external steam equipment using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
