[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , the present invention provides a technical solution: A flue gas purification chimney for generating electricity using the waste heat of molten slag, comprising a chimney main body 1, a filter screen 2 fixedly connected to the inner side above the chimney main body 1, a feed inlet 6 arranged inside the chimney main body 1 above, a discharge outlet 7 arranged inside the chimney main body 1 below, a water storage tank 3 fixedly connected to the outer side of the filter screen 2, a pushing mechanism 4 arranged inside the chimney main body 1, and a swing mechanism 5 arranged on the outer side of the pushing mechanism 4;

[0023] The driving mechanism 4 includes a threaded rod 401 rotatably connected to the middle inside of one side of the chimney main body 1. A first slider 402 is threadedly connected to the outer side of the threaded rod 401. The first slider 402 is slidably connected to the chimney main body 1, and the central axis of the first slider 402 is perpendicular to the central axis of the first guide rod 405, so that the threaded rod 401 can drive the first slider 402 to move horizontally. A first sliding plate 403 is vertically slidably connected to the inner wall of the other side of the chimney main body 1. The outer structure of the first guide hole 404 is an inclined straight line, and the first guide hole 404 and the first guide rod 405 are in clearance fit, so that when the first guide rod 405 moves horizontally, it can drive the first slider 402 to move up and down. A first guide hole 404 is arranged inside the upper part of the first sliding plate 403. A first guide rod 405 is arranged inside the first guide hole 404. The first guide rod 405 is fixedly connected to the first slider 402. A second guide hole 406 is arranged inside the lower part of the first sliding plate 403. A second guide rod 407 is arranged inside the second guide hole 406. One end of the second guide rod 407 close to the first slider 402 is fixedly connected to a bearing plate 408. A first guide groove 409 is arranged inside the middle of the other side of the chimney main body 1. A third guide rod 410 is arranged inside the first guide groove 409. The third guide rod 410 is fixedly connected to the second guide rod 407. The outer structure of the second guide hole 406 is an inclined straight line, and the second guide hole 406 and the second guide rod 407 are in clearance fit. The outer structure of the first guide groove 409 is a horizontal straight line, and the upper and lower surfaces inside the first guide groove 409 are in contact with the upper and lower surfaces of the third guide rod 410. And the outer structure of the third guide rod 410 is a cuboid, so that when the first guide groove 409 moves up and down, it can drive the second guide rod 407 and the third guide rod 410 to move towards the middle and towards the outside.

[0024] The swinging mechanism 5 includes a fourth guide rod 501 fixedly connected to the lower end of the third guide rod 410. A second guide groove 502 communicates with the lower part of the first guide groove 409. The fourth guide rod 501 is nested inside the second guide groove 502. The outer structure of the second guide groove 502 is wavy, and the second guide groove 502 and the fourth guide rod 501 are in clearance fit, so that when the fourth guide rod 501 moves horizontally, it can drive the third guide rod 410 to swing along the track of the second guide groove 502.

[0025] When the slag absorbs heat, the slag is poured into the inside of the bearing plate 408 from the feed port 6. At this time, the outer side of the bearing plate 408 is in contact with the inner wall of the chimney main body 1, so the poured slag is also very close to the chimney main body 1, and the heat can be better absorbed, reducing heat damage.

[0026] When it is necessary to replace the slag, rotate the threaded rod 401 to make the first slider 402 and the first guide rod 405 move horizontally. Since the appearance structure of the first guide hole 404 is an inclined straight line, and the cooperation mode between the first guide hole 404 and the first guide rod 405 is clearance fit, and the connection mode between the first slide plate 403 and the chimney main body 1 is vertical sliding connection, the first slide plate 403 moves downward. Since the appearance structure of the second guide hole 406 is an inclined straight line, and the cooperation mode between the second guide hole 406 and the second guide rod 407 is clearance fit, the appearance structure of the first guide groove 409 is a horizontal straight line, and the upper and lower surfaces of the inner side of the first guide groove 409 are in contact with the upper and lower surfaces of the third guide rod 410, and the appearance structure of the third guide rod 410 is a cuboid, the edge of the second guide hole 406 pushes the second guide rod 407 and the third guide rod 410 to move towards the middle along the track of the first guide groove 409, driving the bearing plate 408 to move towards the middle, so that the slag falls under the action of gravity. When the third guide rod 410 moves horizontally, it drives the inner side of the second guide groove 502 to move horizontally, so that the third guide rod 410, the fourth guide rod 501 and the second guide rod 407 swing reciprocally, making the bearing plate 408 swing reciprocally, making the blanking faster and discharging from the discharge port 7.
