DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution for a flue gas treatment device for a waste incineration power plant: a flue gas treatment device for a waste incineration power plant, comprising a device shell 1, two cleaning components 2 are fixedly connected to the inside of the device shell 1, and alternating filtering components 3 are arranged at the bottom ends of the two cleaning components 2. While the alternating filtering components 3 are alternately filtering, the other can clean the true body through the cleaning component 2, and the outer surface of the alternating filtering component 3 is fixedly connected to the inside of the device shell 1.

[0025] See also Figure 1 The device housing 1 includes a device body 12. Waste ports inclined downward from the inside to the outside are opened on the left and right sides of the device body 12. Dust generated after the cleaning component 2 cleans the alternating filter component 3 is discharged through the waste ports. A smoke outlet channel 11 is fixedly connected to the top of the device body 12, and is connected to the next process device through the smoke outlet channel 11. A smoke inlet 13 is fixedly connected to the bottom end of the device body 12. The bottom end of the smoke inlet 13 is connected to the smoke outlet of the previous device, which guides the smoke into the device body 12. The smoke entering the device body 12 can be sucked out by the suction force of the next device.

[0026] See also Figure 2The alternating filter component 3 includes two active components 34, and the outer surfaces of the two active components 34 are meshed and connected with a synchronous chain 36. The synchronous chain 36 can ensure the synchronous operation of the active components 34. The rear end of the active component 34 is fixedly connected to a forward and reverse motor 35. The forward and reverse motor 35 can change the circuit after a given time, resulting in a change in the rotation direction. The front end of the active component 34 is fixedly connected to a rotating shaft 33. The outer surface of the rotating shaft 33 is fixedly connected to two front and rear parallel connecting columns 32. The two connecting columns 32 are fixedly connected to a filter plate 31 at one end away from the rotating shaft 33. The filter plate 31 can be driven to rotate by the rotating shaft 33. The two filter plates 31 and the connecting column 32 are always located on the same side of the two rotating shafts 33. The filter plate 31 can cover the bottom end of the smoke outlet channel 11. The angles between the two connecting columns 32 and the filter plate 31 are guaranteed to be the same to prevent collision when staggered, and the airflow movement inside the device body 12 is driven by the rotation of the filter plate 31 to achieve a stirring effect.

[0027] The forward and reverse motor 35 is a prior art and will not be explained here.

[0028] See also Figure 3 The active component 34 includes a synchronous gear 341, the front end of which is fixedly connected to the rear end of the rotating shaft 33, and the two synchronous gears 341 are meshed and connected to the inner side of the synchronous chain 36. The rear end of the synchronous gear 341 is fixedly connected to an inner gear ring 342, and a driving column 343 is arranged on the inner side of the inner gear ring 342. The rear end of the driving column 343 is fixedly connected to the front end of the forward and reverse motor 35. The driving column 343 runs through two telescopic grooves in front and back, and a limit spring 344 is fixedly connected in the telescopic groove. One end of the limit spring 344 away from the inner wall of the telescopic groove is fixedly connected to a limited rotation tooth 345, and one end of the limit rotation tooth 345 away from the limit spring 344 extends to the outside of the telescopic groove and an outward angle is an inclined surface. The side of the limit rotation tooth 345 away from the inclined surface is fixedly connected to a fixed column, and the two limit rotation teeth 345 are centrally symmetrical, and the two limit rotation teeth 345 on the left are in opposite directions to the two limit rotation teeth 345 on the right.

[0029] When the forward and reverse motor 35 rotates counterclockwise, the two left limiting teeth 345 drive the left inner gear ring 342 to drive the left synchronous gear 341 and the right synchronous gear 341 to rotate synchronously through the synchronous chain 36, so that the rotating shaft 33 rotates counterclockwise. When the forward and reverse motor 35 rotates counterclockwise, the right limiting teeth 345 will shrink when they touch the inner gear ring 342 due to the setting of the inclined surface, and will pop out through the limiting spring 344 when there is enough space, so that the synchronous chain 36 takes the leading role to reduce the error. Under the counterclockwise rotation of the rotating shaft 33, the left filter plate 31 covers the bottom end of the smoke outlet channel 11, and the right filter plate 31 is cleaned under the right cleaning component 2, and the same applies to the reverse rotation.

[0030] See also Figure 4 The cleaning component 2 includes a component shell 21, and the opposite sides of the two component shells 21 are fixedly connected to the left and right sides of the smoke outlet channel 11. Two sliding grooves that are parallel to each other and run through the front and back are arranged inside the component shell 21. The sliding grooves are slidably connected to the limiting components 23. The end of the limiting component 23 away from the smoke outlet channel 11 is fixedly connected to a tension spring 22, and the end of the tension spring 22 away from the limiting component 23 is fixedly connected to the inner side of the component shell 21. A driving groove is arranged between the two sliding grooves of the component shell 21, and a driving component 26 is slidably connected in the driving groove. A starting block 25 is fixedly connected to the side between the driving groove and the sliding groove close to the smoke outlet channel 11. The bottom ends of the two limiting components 23 extend to the outside of the sliding groove and are jointly fixedly connected to a cleaning brush 24. The tops of the two limiting components 23 are jointly fixedly connected to a reset rod 27. The starting block 25 is close to one end of the sliding groove and is away from the outward angle of the smoke outlet channel 11. The bottom end of the cleaning brush 24 is close to the top of the filter plate 31.

[0031] The limit assembly 23 is driven to move by the driving assembly 26, and the tension spring 22 is stretched at the same time. After the limit assembly 23 touches the starting block 25, the contraction component causes the limit assembly 23 to move together with the contraction of the tension spring 22, driving the cleaning brush 24 connected to the bottom end of the limit assembly 23 to clean the filter plate 31.

[0032] See also Figure 4 The driving assembly 26 includes a rotating wheel 261, which is fixedly connected to the top inner side of the component housing 21. A driving motor is provided at the top of the rotating wheel 261, and a rotating column 262 is fixedly connected to the bottom end of the rotating wheel 261. The rotating column 262 is driven to rotate by the driving motor. A moving block 263 is slidably connected to the side of the bottom end of the rotating column 262 away from the rotating wheel 261. The moving block 263 can slide on the rotating column 262 and slide in the driving groove, so that the rotating column 262 can drive the moving block 263 to reciprocate left and right. The moving block 263 is fixedly connected to the limiting blocks 264 on both sides close to the limit assembly 23. The moving block 263 is slidably connected in the driving groove. The limit block 264 is away from one end of the moving block 263 and away from the outward angle of the starting block 25, and the inclined surface of the limit block 264 can enable the limit block 264 to pass through the limit assembly 23 to reach the outside of the limit assembly 23 and then lift the limit assembly 23 through the plane.

[0033] See also Figure 5The limiting assembly 23 includes a connecting block 231, which slides in the sliding groove and has its bottom end fixedly connected to the top of the cleaning brush 24. A reset groove is provided inside the connecting block 231, and a pulling block 233 is slidably connected in the reset groove. The pulling block 233 can extend to the outside of the connecting block 231 through the reset groove. The end of the pulling block 233 close to the connecting block 231 is fixedly connected to a reset spring 232, and the end of the reset spring 232 away from the pulling block 233 is fixedly connected to the reset groove. The outward angle of the pulling block 233 closest to the starting block 25 is an inclined surface.

[0034] When the inclined surface of the pulling block 233 is able to contact the inclined surface of the limit block 264, the pulling block 233 is retracted, allowing the limit block 264 to pass, and after passing, it is reset and extended by the reset spring 232, so that the limit block 264 can drive the connecting block 231 to move through the plane contact with the pulling block 233. When the inclined surface of the pulling block 233 contacts the inclined surface of the starting block 25, the pulling block 233 is retracted, so that the pulling block 233 is separated from the drive of the limit block 264, and the connecting block 231 will be reset under the drive of the tension spring 22 and clean the dust accumulated on the filter plate 31, and the dust is discharged through the waste port.

[0035] Working principle:

[0036] First, connect the smoke inlet 13 to the smoke outlet of the previous device, and connect the smoke outlet 11 to the smoke inlet of the next device. By starting the device, the forward and reverse motors 35 drive the active component 34 to drive the two rotating shafts 33 together, and drive the two filter plates 31 to perform staggered filtering. In the staggered process, the movement process can stir the airflow in the cabin of the device body 12 to prevent impurities from accumulating. The filter plate 31 that has not been filtered will rotate to the bottom of the cleaning component 2 so that the cleaning brush 24 is close to the filter plate 31, and is driven by the limit component 23 for cleaning. The accumulated impurities after cleaning are discharged through the waste port.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
