Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a flue gas diversion device. Background Technology

[0002] When flue gas enters the treatment device from the flue, if it directly impacts the internal structure, it will cause excessively high local flow velocity and turbulent airflow, leading to the following problems: First, flue gas will stagnate in some areas, preventing pollutants from fully contacting the treatment medium and reducing the purification effect; second, high-speed airflow may wash away the inner walls or components of the equipment, accelerating wear and shortening the equipment's lifespan; third, uneven airflow distribution will lead to uneven loads on subsequent treatment units, affecting overall stability. Therefore, it is necessary to use a diversion device to guide the flow. Common measures include diversion plates, but during long-term use, a large amount of soot will adhere to the surface of the diversion plate.

[0003] A search revealed a Chinese patent publication number CN218154278U, which discloses a flue gas guiding device, including a first flue and a second flue. The second flue is fixedly connected to the first flue on one side. A rectifier grid assembly is provided inside the first flue near the flue gas inlet, and a variable diameter grid assembly is provided inside the first flue away from the flue gas inlet. The two ends of the rectifier grid assembly and the two ends of the variable diameter grid assembly are fixedly connected to the inner wall of the first flue. A support is provided on the outer surface of the second flue near the bottom.

[0004] To address the problem that while the aforementioned technologies can change the angle, they cannot effectively solve the issue of large amounts of smoke and dust accumulating above and being unable to be cleaned, a flue gas diversion device is proposed. Utility Model Content

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-5As shown, a flue gas diversion device includes a flue pipe 1 with multiple diversion plates 2 fixedly connected inside. Multiple flip baffles 6 are rotatably connected inside the diversion plates 2. A flip drive assembly is fixedly connected to one side of the flip baffle 6. A cleaning brush 11 is slidably connected to the rear side of the flip baffle 6. Dust suction plates 17 are fixedly connected to both sides of the cleaning brush 11. A translation assembly is fixedly connected to one end of the cleaning brush 11.

[0030] Multiple diversion plates 2 are combined to guide the airflow into the subsequent processing steps at a certain angle; the diversion plate 2 is used to guide the flue gas. One side has a groove, and the diversion effect is achieved through multiple flip baffles 6 inside. The flip baffles 6 have rounded corners on both sides, and adjacent flip baffles 6 fit together when diverting the flow.

[0031] The flipping drive assembly includes a synchronous pulley set 18, a drive motor 19, a drive wheel 20, and a synchronous belt 21. The drive motor 19 is fixedly connected to the inner wall of the diversion plate 2, the drive wheel 20 is fixedly connected to the power output end of the drive motor 19, the synchronous pulley set 18 is fixedly connected to one side of the flipping baffle 6, and multiple synchronous pulley sets 18 are connected to each other through the synchronous belt 21. One side of the synchronous pulley set 18 and the drive wheel 20 are connected through the synchronous belt 21.

[0032] When the flip-up baffle 6 is used for a long time and one side is filled with smoke and dust, the drive motor 19 starts and drives the drive wheel 20 to rotate 180 degrees. Then, through multiple synchronous belts 21 and synchronous pulley sets 18, all the flip-up baffles 6 are rotated 180 degrees, so that the clean side is used for diversion. The smoke and dust are cleaned by the reciprocating cleaning brush 11. This ensures the diversion effect during use and cleans the smoke and dust that affects the diversion effect.

[0033] In this embodiment, the translation component includes a lifting bracket 7, a drive screw 9, a screw motor 10, and a screw nut 12. The screw nut 12 is fixedly connected to one side of the cleaning brush 11. Both ends of the drive screw 9 are rotatably connected to the lifting bracket 7. One end of the screw motor 10 is fixedly connected to one side of the lifting bracket 7. The power output end of the screw motor 10 is fixedly connected to one end of the drive screw 9. The screw nut 12 is threadedly connected to the drive screw 9.

[0034] Driven by the screw motor 10, the screw 9 drives the cleaning brush 11 to move laterally through the screw nut 12, and cleans the dust by brushing the brush bristles that are in contact with the side of the flip-up baffle 6.

[0035] Multiple lifting support frames 15 are fixedly connected to the inner wall of the diversion plate 2, and one end of the lifting support frame 15 is slidably connected to the inner side of the lifting bracket 7.

[0036] The lifting support frame 15 makes the lifting bracket 7 more stable when it moves up and down.

[0037] In this embodiment, a lifting motor 13 is fixedly connected to the inner wall of the diversion plate 2, and a cam 14 is fixedly connected to the power output end of the lifting motor 13. The side wall of the cam 14 is slidably connected to the lifting bracket 7.

[0038] Springs 16 are fixedly connected to the inner walls of the lifting bracket 7 and the diversion plate 2.

[0039] When cleaning is required, the lifting bracket 7 can be pressed down by rotating the cam 14 so that the bristles can fit against the flip baffle 6. When the flip baffle 6 flips, the rotating cam 14 will rotate and no longer press the lifting bracket 7. The spring 16 will pull the lifting bracket 7 up so that the bristles do not contact the flip baffle 6 and prevent the bristles from being clamped when the flip baffle 6 rotates.

[0040] In this embodiment, a translation slide bar 8 is fixedly connected to one side of the lifting bracket 7. The translation slide bar 8 is slidably connected to the cleaning brush 11, and the translation slide bar 8 can make the cleaning brush 11 move more stably.

[0041] In this embodiment: multiple diversion plates 2 are combined to guide the airflow at a certain angle into the subsequent processing steps; the diversion plate 2 has a groove on one side for guiding the flue gas, and the diversion effect is achieved by multiple flip baffles 6 inside. The flip baffles 6 have rounded corners on both sides, and adjacent flip baffles 6 fit together when diverting the flow.

[0042] When the flip-up baffle 6 is used for a long time and one side is filled with smoke and dust, the drive motor 19 starts and drives the drive wheel 20 to rotate 180 degrees. Then, through multiple synchronous belts 21 and synchronous pulley sets 18, all the flip-up baffles 6 are rotated 180 degrees, so that the clean side is used for diversion. The smoke and dust are cleaned by the reciprocating cleaning brush 11. This ensures the diversion effect during use and cleans the smoke and dust that affects the diversion effect.

[0043] Driven by the screw motor 10, the screw 9 drives the cleaning brush 11 to move laterally through the screw nut 12. The brush bristles that are in contact with the flip baffle 6 clean the dust. The lifting support frame 15 makes the lifting bracket 7 more stable when it moves up and down.

[0044] When cleaning is required, the lifting bracket 7 can be pressed down by rotating the cam 14 so that the bristles can fit against the flip baffle 6. When the flip baffle 6 flips, the rotating cam 14 will rotate and no longer press the lifting bracket 7. The spring 16 will pull the lifting bracket 7 up so that the bristles do not contact the flip baffle 6 and prevent the bristles from being clamped when the flip baffle 6 rotates.
