Abstract

The invention discloses a flue gas filtering device which comprises a flue gas pipe, a mounting frame, amounting plate and a linkage assembly; the mounting frame is mounted on the inner wall of the flue gas pipe, a rotating disc is rotationally mounted on the outer side of the mounting frame, mounting blocks are mounted on the circumferential side of the rotating disc, and scrapers are mounted on the mounting blocks; the mounting plate is mounted on the inner wall of the flue gas pipe, and a motor is mounted on the mounting plate; and the linkage assembly is installed on the mounting frame and acts on the rotating disc, and the motor is connected with the linkage assembly. According to the flue gas treatment device, when flue gas circulates in the flue gas pipe and an output shaft of the motor rotates, the linkage assembly drives the rotating disc to rotate, the scraping plate rotates in the axis direction of the rotating disc, and when the scraping plate rotates, one end of the scraping plate makes contact with the inner wall of the flue gas pipe, dust, particles and the like on the inner wall of the flue gas pipe are scraped off, and caking on the inner wall of the flue gas pipe is prevented; and compared with an existing device, the device can prevent the inner wall of the flue gas pipe from caking and avoiding blockage, the service life of the filtering device is greatly prolonged, the overall structural design is ingenious, and the device is suitable for industrial popularization and application.

Example Embodiment

[0033] Example 1
[0034] like figure 1 , figure 2 , Figure 4 with Figure 9 As shown, a flue gas filtration device proposed in this embodiment is suitable for the use of fire power plants, including: flue gas pipes 1, mounting frame 2, mounting plate 6, inter-action assembly 8, mounting frame 2 mounted in flue gas pipe 1 On the inner wall, the mounting frame 2 is rotated and mounted with a rotating disk 3 coaxial with the flue gas pipe 1, and the mounting block 4 is mounted on the rotary disk 3 circumferential side, and the mounting block 4 is mounted to clean the wiper of the inner wall of the flue gas pipe 1. 5. The mounting plate 6 is mounted on the inner wall of the flue gas pipe 1 and is located away from the mounting frame 2 away from the blade 5, and the mounting plate 6 is mounted on the mounting plate 6, and the communication assembly 8 is mounted on the mounting frame 2 and acts on the rotating plate 3. The output shaft of the motor 7 is connected to the intermediate assembly 8. When the output shaft of the motor 7 is rotated, the rotating disk 3 drives the rotating disk 3 along the axis, when the flue gas flows from the flue gas pipe 1, the motor 7 The output shaft is rotated, and the rotation disk 3 is rotated by the intermediate assembly 8, so that the scraper 5 mounted on the mounting block 4 is rotated in the axial direction of the turntable disk 3, and the squeegee 5 rotates one end and smoke The inner wall of the tube 1 is in contact, thereby scraping the dust and particulate matter in the inner wall of the flue gas pipe 1, thereby preventing the flungeon 1 inner wall of the flue gas pipe 1, and the flue gas filtration device of the present invention can prevent smoke as compared with the existing device. The inner wall of the tube 1 is to avoid clogging, thereby increasing the life of the filter device.
[0035] like figure 2 , Figure 4 , Figure 7 with Figure 9 As shown, the communication assembly 8 includes a first cone gear 9 that is rotatably mounted on the mounting frame 2 and coaxial with the flue gas pipe 1, and the center of the first cone gear 9 outputs an axis connection with the motor 7, the inner wall of the mounting frame 2 The rotating rod 10 is mounted on the bearing, and the second tapered gear 11 that is engaged with the first cone gear 9 is mounted by the bearing 10, and the other end of the rotor 10 is outside the mounting frame 2 and the third cone 12 is mounted. The rotating plate 3 is rotated to be mounted on the outer side of the mounting frame 2 and is configured with the third cone gear 12, and the output shaft rotation of the motor 7 is rotated to rotate, so that the second cone gear 11 Turn, the second bevel gear 11 is rotated, and the third cone 12 is rotated by the rotary rod 10, since the third cone gear 12 meshes such that the rotating disk 3 is rotated, thereby achieving the blade 5 rotation.
[0036] like image 3 with Figure 7As shown, the mounting block 4 includes a connection block 17 that is fixed to the guide block 16, and the connection block 17 is open and sliding mounting has a sliding block 18, and there is a plurality of springs and the connecting block 17. The blade 5 is mounted on the sliding block 18, and the design of the spring is mounted in the pipe, and the blade 5 can move in the axial direction of the flue gas pipe 1, thereby facilitating the installation of the device, and the design of the spring also makes the blade 5 can be in contact with the inner wall of the flue gas pipe 1 to prevent a gap between the blade 5 and the flue gas pipe 1.
[0037] like figure 2 , image 3 , Figure 5 , Image 6 with Figure 7 , The flue gas duct inner wall is attached to the connecting plate 14, the blade 14 close to the direction of the connecting plate 5 is attached to the connecting rod 15, one end of the connecting rod 15 is attached to the guide block 16, connected to the other end of the guide block 17 is connected to the block 16 The outer peripheral side and the outer surface of the guide block 16 can be rotated, and the design of the guide block 16 can reduce the jitter when the flue gas pipe 1 occurs, thereby improving the cleaning effect of the scraper 5.
