[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] like Figures 1 to 4As shown, a filtering device for treating incineration waste gas comprises an air inlet pipe 1, one end of which is connected to a connecting pipe 3 through a flange ring, a purification box 2 is fixed to the other end of the connecting pipe 3, an air outlet pipe 4 is fixed to the other end of the purification box 2, two symmetrically distributed rotating gear rings 10 are rotatably installed on the inner side of the connecting pipe 3, the inner surface of the rotating gear ring 10 close to the purification box 2 is provided with transmission teeth and is connected to a rotating gear 14 through the meshing of the transmission teeth, a rotating motor 13 is fixed to the axial direction of the rotating gear 14, a supporting plate 16 is installed on the outer side of the rotating motor 13 and the top of the supporting plate 16 is fixed to the inner wall of the purification box 2, a dust cleaning scraper 11 is fixed between the two rotating gear rings 10, arc-shaped connecting blocks 12 are fixed to one side of both ends of the dust cleaning scraper 11, a rotating plate 9 is rotatably installed on the bottom of the connecting pipe 3, two contact sensing probes 15 are fixed on the inner wall of the connecting pipe 3, and an electric telescopic Rod 17, both ends of the electric telescopic rod 17 are rotatably connected with the rotating plate 9 and the connecting pipe 3, a collecting frame 8 is installed under the electric telescopic rod 17, and the collecting frame 8 is detachably connected with the connecting pipe 3, and the contact sensing probe 15 is electrically connected with the electric telescopic rod 17. After the rotating motor 13 is energized, it drives the rotating gear 14 to rotate counterclockwise. At this time, the rotating gear 14 drives the rotating gear ring 10 and the cleaning scraper 11 to rotate counterclockwise at the same time, and the rotating cleaning scraper 11 drives the arc-shaped connecting block 12 to pass over the contact sensing probe 15. At this time, the electric telescopic rod 17 starts to pull the rotating plate 9, so that the rotating plate 9 rotates downward to open an opening at the bottom of the connecting pipe 3. The rotating cleaning scraper 11 passes over the rotating plate 9 and sends the dust scraped from the inner wall of the connecting pipe 3 into the collecting frame 8, so as to remove and collect the dust on the inner wall of the connecting pipe 3 and avoid dust corrosion on the inner wall of the pipeline.
[0023] The upper surface of the arc-shaped connecting block 12 is flush with the inner wall of the connecting tube 3, the center of the contact sensing probe 15 coincides with the axis of the connecting tube 3, the outer wall of the contact sensing probe 15 is in sliding contact with the inner wall of the connecting tube 3, the contact sensing probe 15 and the arc-shaped connecting block 12 are in the same vertical plane, and the arc length of the arc-shaped connecting block 12 is greater than the arc length of the rotating plate 9, ensuring that the arc-shaped connecting block 12 passes directly above the contact sensing probe 15 during rotation, and the rotating plate 9 can be opened in advance before the cleaning scraper 11 reaches above the rotating plate 9, so that the dust scraped from the connecting tube 3 can enter the collection frame 8.
[0024] like Figure 2As shown, a plurality of linearly arranged activated carbon filter plates 6 are slidably installed on the upper surface of the purification box 2, and the two sides and the bottom of the activated carbon filter plate 6 are in contact with the inner wall and the inner bottom of the purification box 2, and a movable cover plate 5 is installed on the top of the activated carbon filter plate 6, the width dimension of the movable cover plate 5 is larger than the width dimension of the activated carbon filter plate 6, and the length dimension of the movable cover plate 5 is larger than the maximum distance between the two farthest activated carbon filter plates 6, and a plurality of strip grooves are provided on the bottom surface of the movable cover plate 5, and the top end of the activated carbon filter plate 6 is snapped into the strip groove, and the movable cover plate 5 is pulled upward to slide the activated carbon filter plate 6 out of the purification box 2, so that the activated carbon filter plate 6 that has been clogged with dust for a long time can be removed for cleaning or replacement, so as to ensure the recycling of the device.
[0025] Two magnets 7 are fixedly embedded on the upper surface of the purification box 2 , and the magnets 7 are connected to the movable cover 5 by magnetic adsorption. The magnetic adsorption of the movable cover 5 by the magnets 7 is used to increase the sealing performance of the connection between the movable cover 5 and the purification box 2 .
[0026] Working principle: Turn on the power of the device. After the power is turned on, the waste gas generated by incineration enters the connecting pipe 3 through the air inlet pipe 1, and the waste gas enters the purification box 2 from the connecting pipe 3. The waste gas will pass through the multiple activated carbon filter plates 6 that are slidably inserted in the purification box 2. The activated carbon filter plates 6 absorb and purify the dust and harmful substances in the waste gas. The purified airflow will be discharged outward through the outlet pipe 4. During the long-term transportation of waste gas by the connecting pipe 3, the dust in the waste gas will adhere to the inner wall of the connecting pipe 3. At this time, the rotating motor 13 is powered on and starts, and drives the rotating gear ring 10 and the cleaning scraper 11 to rotate counterclockwise through the rotating gear 14. When the cleaning scraper 11 rotates, it will drive the arc-shaped connecting block 12 to pass over the contact sensing probe 15. At this time, the electric telescopic rod 17 will pull the rotating plate 9 downward, so that the rotating plate 9 rotates downward to expose a gap at the bottom of the connecting pipe 3. When the cleaning scraper 11 rotates and passes through the rotating plate 9, the dust scraped from the connecting pipe 3 will be sent into the collecting frame 8 through the gap. After the cleaning scraper 11 passes the contact sensing probe 15, the electric telescopic rod 17 will push the rotating plate 9 to recover, so as to ensure the sealing of the connecting pipe 3, remove and collect the dust on the inner wall of the connecting pipe 3, and avoid dust corrosion on the inner wall of the pipeline.
