Embodiment 1
[0027] Such as Figure 1-2 As shown, the present invention provides a high-temperature flue gas flow regulating device, including a regulating plate 1, a swing arm 2, a rotating shaft 3, a flue gas channel body 5, a driving mechanism 4 and a sealing structure 6, on both sides of the flue gas channel body 5 Set the swing arm 2, the front end of the swing arm 2 is fixedly connected to the adjustment plate 1, and the rear end is hinged to the rotating shaft 3, and the rotating shaft 3 can be fixedly installed on the flue gas channel body 5, and can also be fixedly installed on other external foundations; the swing arm 2 and the The driving mechanism 4 is hingedly connected, so that the swing arm 2 can rotate around the rotating shaft 3 through the driving mechanism 4, and drive the adjustment plate 1 to be partially or completely inserted into the flue gas channel body 5 from top to bottom, so as to adjust the flow of high-temperature flue gas in the flue gas channel. The flow ar...
Embodiment 2
[0034] Such as image 3 As shown, the difference between this embodiment and the first embodiment is that at least one strut 8 is arranged on the crossbeam 7, and the driving mechanism 4 corresponding to the number of struts 8 is fixedly installed on the outside of the flue gas passage body 5, And the driving mechanism 4 is hingedly connected to the strut 8 . In this example, a strut 8 is provided in the middle of the crossbeam 7, and the drive mechanism 4 is provided with one, and the driving mode is a telescopic push rod 41 type, on which the telescopic push rod 41 is connected with the strut 8, which is hydraulically driven or Pneumatic drive or screw drive; in this way, through the action of the telescopic push rod 41, the strut 8 can drive the adjustment plate 1 to perform an insertion or extraction action relative to the flue gas channel body 5. Of course, in different embodiments, the driving mechanism 4 hingedly connected to the swing arm 2 and the strut 8 may also be...
Embodiment 3
[0036] Such as Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment is that: the driving mechanism 4 shown adopts a crank 42 connecting rod 43 drive mode, including a crank 42 and a connecting rod 43, and the crank 42 is fixedly installed on the foundation, and through The connecting rod 43 is hingedly connected to the swing arm 2, wherein the base can be the flue gas passage body 5 or other foreign objects; of course, in different embodiments, the crank 42 connecting rod 43 type driving mechanism 4 can also be connected to the crossbeam 7 On the strut 8, the above-mentioned purpose can be achieved equally.
