Based on the embodiments of 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. Specific embodiment 1

[0030] See also Figure 1-7 The utility model is a smoke particle capture device for a double-drum boiler, comprising a fixed flange 1, a smoke inlet pipe 2 is fixed at one end of the fixed flange 1, and a filter chamber 3 is fixedly connected to one end of the smoke inlet pipe 2; a smoke outlet pipe 5 is fixed to one side of the filter chamber 3, a collection box 6 is snap-fitted at the bottom of the filter chamber 3, a filter assembly 4 is arranged at the top of the filter chamber 3, and the filter assembly 4 comprises a double-shaft motor 401 fixed to the top of the filter chamber 3, a transfer rod 402 is fixed at both output ends of the double-shaft motor 401, cams 403 are fixed to the side surfaces of the two transfer rods 402, a follower rod 404 is slidably fitted to the side surfaces of the cam 403, a fixed plate 405 is fixed to one end of the follower rod 404, and a fixed plate 405 is fixed to one end of the follower rod 404. The bottom of the fixed plate 405 is located on both sides of the driven rod 404, and connecting columns 406 are fixed on both sides, and impact balls 407 are fixed on one end of the two connecting columns 406. Springs 408 are sleeved on the sides of the two connecting columns 406, and one end of the spring 408 is fixedly connected to the top outside the filter chamber 3, and the other end of the spring 408 is fixedly connected to the bottom of the fixed plate 405. A turntable 409 is fixed on one end of the two transfer rods 402, and a centrifugal column 410 is fixed on one side of the two turntables 409 away from the center. A connecting plate 411 is rotatably matched with the side of the centrifugal column 410, and one end of the connecting plate 411 is rotatably matched with a fixed rod 412, and a connecting plate 413 is fixed to one end of the fixed rod 412.

[0031] Specifically, the filter chamber 3 has a plurality of filter screens 415 that are slidably matched in a linear array, and the plurality of filter screens 415 are fixedly connected to the connecting plate 413. Two symmetrical impact plates 414 are fixed on the top of the plurality of filter screens 415. The filter chamber 3 has a plurality of slide grooves 301 that are slidably matched with the filter screens 415. The filter chamber 3 has two opposite inner walls that are respectively provided with slide grooves 302 that are slidably matched with the two connecting plates 413. The inner wall of the slide groove 302 is penetrated by a slide groove 303 that is slidably matched with the fixed rod 412.

[0032] The operation process of this embodiment is as follows: when filtering, the dual-axis motor 401 is started to drive the transfer rod 402 to rotate, and the transfer rod 402 drives the cam 403 and the turntable 409 to rotate synchronously. During the rotation of the cam 403, the driven rod 404 slides along the contour of the cam 403, so that the driven rod 404 moves up and down along the vertical direction. The driven rod 404 drives the fixed plate 405 fixed thereto to move. When the fixed plate 405 moves upward, it pulls the spring 408 to extend. At the same time, the driven rod 404 drives the two connecting columns 406 fixed at the bottom of the fixed plate 405 to move synchronously. The connecting column 406 drives the impact ball 407 fixed at one end thereof to move up and down reciprocatingly. During the rotation of the turntable 409, the centrifugal column 410 fixed at one side of the turntable 409 also moves in a circular motion. At the same time, the centrifugal column 410 drives the connecting plate 411 to rotate. At this time, the connecting plate 411 drives the fixing rod 412 to move up and down along the sliding groove 303. The fixing rod 412 drives the connecting plate 413 to move in the sliding groove 2 302 at the same time. The connecting plate 413 drives the plurality of filter screens 415 fixed thereto to move up and down reciprocatingly, and the impact plates 414 fixed on the top of the plurality of filter screens 415 also move accordingly.

[0033] The vertical stroke of the driven rod 404 driven by the cam 403 is greater than the vertical stroke of the connecting plate 413 driven by the turntable 409, and when the cam 403 drives the driven rod 404 to move to the lowest position, the turntable 409 also drives the connecting plate 413 to move to the lowest position. At this time, the impact ball 407 fixed at one end of the connecting column 406 is in contact with the top of the impact plate 414, and the spring 1 408 is in a non-deformed state. In the process of the cam 403 driving the driven rod 404 from the highest position to the lowest position, the impact ball 407 will make the first impact with the impact plate 414 in the middle. In this way, under the action of the spring 1 408, the impact ball 407 will also reciprocately impact the impact plate 414 after the first impact, causing the filter screen 415 to vibrate, and the smoke particles stuck in the mesh will be shaken off.

[0036] The operation process of this embodiment is as follows: when it is necessary to remove the smoke particles in the collection box 6, the pull rod 607 is pulled to disengage the clamping column 606 fixed to the pull rod 607 from the fixing hole 306, so that the collection box 6 can be pulled to the right to disengage the clamping plate 602 from the guide rail 305;

[0037] When installing the collection box 6, pull the pull rod 607, at this time the spring 2 608 is squeezed, and then the clamping plate 602 and the guide rail 305 are connected, and the collection box 6 is pushed to the left. After the clamping plate 602 and the guide rail 305 are fully engaged, the pull rod 607 can be released, and the spring 2 608 drives the clamping column 606 to engage in the fixing hole 306, so as to fix the collection box in the horizontal direction.

At this time, the water flow in the water pipe 701 sprays water mist through the water mist nozzle 702, and the water mist absorbs toxic gases such as carbon monoxide and sulfur dioxide in the smoke. At the same time, sewage is discharged through the sewage outlet 703.
