Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas damper technology, specifically a multifunctional integrated modular flue gas damper that effectively prevents leakage. Background Technology
[0002] Flue gas dampers are key components in industrial flue gas emission and treatment systems. They are used to control the flow path of flue gas. They can flexibly adjust their opening to control the flow of flue gas according to the system's operating requirements. They can also be closed during equipment maintenance, malfunctions, or emergencies to prevent flue gas leakage, ensure the safe and stable operation of the system, and reduce environmental pollution.
[0003] Existing flue gas dampers rely entirely on electric current for operation. Under normal conditions, a continuous current supply maintains the opening and closing of the damper. However, if the current is cut off, the damper loses its driving power and cannot effectively perform its smoke extraction function. Furthermore, the emergency opening mechanism in existing technologies has limitations. Operators typically need to manually rotate the corresponding components to open the damper. Due to the relatively cumbersome and slow operation, it is difficult to quickly open the damper for timely smoke extraction in emergency situations involving rapid flue gas impact. Therefore, we propose a multifunctional, integrated, modular, and leak-proof flue gas damper. Utility Model Content

[0013] In some embodiments, a sealing component is provided in each of the two elongated slots, and the two sealing components are arranged opposite to each other for sealing the door.
[0014] In some embodiments, the sealing assembly includes a support frame fixedly connected to the outside of the outer door frame, a hydraulic rod fixedly connected to the outside of the support frame, a sealing plate slidably connected within the elongated groove, and a drive end of the hydraulic rod fixedly connected to the sealing plate.
[0015] This utility model has at least the following beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] Please see Figures 1-6 This utility model provides a technical solution:
[0026] A multifunctional integrated modular effective leak-proof flue gas damper door includes an outer door frame 1, an inner door frame 2, and a damper assembly 5. The inner door frame 2 has through-holes 3 on both sides, with both through-holes extending out of the outer door frame 1. A support frame 4 is fixedly connected inside the inner door frame 2. The damper assembly 5 is located inside the inner door frame 2 and includes a first connecting block 51 and a door body 55. The door body 55 is located between the first connecting block 51 and the second connecting block 52. The top and bottom of the door body 55 are respectively engaged with two connecting slots 53. The damper assembly 5 includes a driving component 56 for driving the door body 55 to rotate and open. An emergency component 6 is located inside and outside the inner door frame 2. The emergency component 6 includes an emergency plate 61 and a rigging component 65. A cable 654 is installed inside the rigging component 65 for connecting the emergency plate 61, and the rigging component 65 is used to drive the emergency plate 61 to fall quickly, thereby facilitating emergency smoke exhaust.
[0027] The baffle assembly 5 includes a first connecting block 51 fixedly connected inside the inner door frame 2, a second connecting block 52 provided on the top of the first connecting block 51, and the second connecting block 52 fixedly connected to the bottom of the support frame 4. Both the first connecting block 51 and the second connecting block 52 are provided with connecting grooves 53, and the two connecting grooves 53 face opposite directions. A shaft 54 is rotatably connected inside the inner door frame 2, and a door body 55 is fixedly connected outside the shaft 54. A driving component 56 is provided outside the outer door frame 1 to drive the door body 55 to rotate. The driving component 56 includes a frame 561 fixedly connected to the outside of the outer door frame 1, and a motor 562 fixedly connected inside the frame 561. The driving end of the motor 562 is fixedly connected to the shaft 54. The motor 562 drives the shaft 54 to rotate, which synchronously drives the door body 55 to rotate, which can prevent leakage and exhaust smoke.
[0028] Emergency component 6 includes an emergency plate 61 that is slidably connected to the outside of the support frame 4, a rotating shaft 62 that is rotatably connected inside the support frame 4, a first wheel 63 that is fixedly connected to the outside of the rotating shaft 62, a second wheel 64 that is rotatably connected to the outside of the support frame 4, and a rigging 65 that is provided outside the outer door frame 1.
[0029] The rigging component 65 includes two support plates 651 fixedly connected to the outside of the outer door frame 1. A rotating roller 652 is rotatably connected between the two support plates 651. A wire roller 653 is fixedly connected to the outside of the rotating roller 652. A cable 654 is wound around the wire roller 653. The cable 654 passes through the outer door frame 1 and sequentially passes through the second wheel body 64 and the first wheel body 63, and is fixedly connected to the emergency plate 61. A first torsion spring 655 is sleeved at both ends of the rotating roller 652. A ratchet 656 is fixedly sleeved at the bottom end of the rotating roller 652. An L-shaped rod 657 is fixedly connected to the top of the support plate 651 at the bottom position. A pawl is rotatably connected to the bottom of the L-shaped rod 657. 658, the pawl 658 and the ratchet 656 are engaged. A second torsion spring 659 is provided between the connecting end of the pawl 658 and the L-shaped rod 657 and the support plate 651. The end of the pawl 658 is fixedly connected to the pull rod 6510. The top of the rotating roller 652 passes through the support plate 651 at the top position and is fixedly connected to the rotating wheel 6511. Rotating the rotating wheel 6511 can drive the rotating roller 652 to rotate. The rotation of the rotating roller 652 can drive the cable 654 to be retracted. In this way, the emergency plate 61 can be returned to its position. It should be noted that the length of the cable 654 needs to be preset to avoid the cable 654 being too long and getting stuck between the door body 55 and the support frame 4.
[0030] When in use, start the motor 562, which drives the shaft 54 to rotate, synchronously driving the door 55 to rotate, thus preventing leakage and venting smoke. In the event of a power outage, pull the lever 6510 directly. The lever 6510 drives the pawl 658 to rotate, thereby releasing the ratchet 656. In this way, the rotating roller 652 will rotate rapidly under the torque of the two first torsion springs 655, which in turn causes the cable 654 outside the wire roller 653 to be released quickly. At this time, because the cable 654 is released, the emergency plate 61 will immediately fall, thereby exposing the support frame 4, and the smoke can be discharged from the support frame 4. Thus, simply pulling the lever 6510 can quickly vent smoke. Example 2
[0031] Please see Figures 5-6 This utility model provides a technical solution:
[0032] Unlike Embodiment 1, both long grooves 3 are provided with sealing components 7, and the two sealing components 7 are arranged opposite to each other to seal the door 55.
[0033] The sealing assembly 7 includes a support frame 71 fixedly connected to the outside of the outer door frame 1, a hydraulic rod 72 fixedly connected to the outside of the support frame 71, and a sealing plate 73 slidably connected inside the long groove 3. The driving end of the hydraulic rod 72 is fixedly connected to the sealing plate 73.
[0034] Activating two sets of opposing hydraulic rods 72 drives two sealing plates 73 to move within the long groove 3, which can seal the gap between the door body 55 and the inner door frame 2 after the door body 55 is rotated and closed, thus preventing leakage.
[0035] Furthermore, the snap-fit between the two connecting grooves 53 and the door body 55 also has a sealing effect. In conjunction with the sealing component 7, it can effectively prevent leakage. In addition, the sliding connection between the emergency plate 61 and the support frame 4 also has a sealing effect.
