Double baffle fluorine lined flue gas baffle door with sealed air

Abstract

The utility model relates to a flue gas sealing technical field especially, more specifically to a double baffle fluorine lining flue gas baffle door with sealing air, including frame body, still including barrier and coupling driving part, frame body is provided with two, two frame bodies are centrally symmetric distribution, and the left and right ends of frame body are uniformly distributed and are opened to have the mounting hole, two are sealed and are connected through the flange and pass through a plurality of mounting holes, and the inner wall four sides of frame body are fixedly connected with sealing plate, and the left and right sides of sealing plate are opened to have the through groove, the utility model discloses two frame bodies are centrally symmetric distribution design, and this layout makes barrier more stable and balanced on the structure, can better bear the pressure and impact force of flue gas, and simultaneously convenient to install and maintain, and the two barrier and sealing connecting piece that set up on the device make sealing air enter two air chambers after barrier closing, effectively prevent flue gas from the tiny gap between barrier and sealing plate, frame body and leak, form third stage seal.

The shaft (103) is located on the side away from the two sealing plates (107). The end of the baffle plate (104) near the sealing plate (107) is arc-shaped and fits against the sealing plate (107). When the baffle plate (104) is in a vertically downward state, it blocks the flow groove (108) on the sealing plate (107). The three baffle plates (104) are jointly provided with a coupling drive component. The two frames (1) are jointly provided with a sealing air connector above them.

2. A double damper fluoropolymer lined flue gas damper door with sealed air according to claim 1, characterized in that: The coupling drive includes a hinge plate (5), a hinge rod (501) and a fixed rod (502). The shaft (103) passes through the front and rear ends of the frame (1) and is provided with bearing seats (106). The hinge plate (5) is fixedly connected to the shaft (103) on the outside of the bearing seats (106).

3. A double damper fluoropolymer lined flue gas damper door with sealed air according to claim 2, characterized in that: Two hinge rods (501) are fixed to one end of the hinge plate (5) away from the bearing seat (106), and a fixed rod (502) is connected to the three vertically arranged hinge rods (501).

4. A double-baffle fluoropolymer-lined flue gas damper door with air sealing as described in claim 1, characterized in that: The front and rear ends of the barrier plate (104) are not in contact with the inner wall of the frame (1). Two sealing shafts (105) are fixed to the outer wall of the shaft (103). The front and rear ends of the barrier plate (104) and the two sealing shafts (105) are in contact with each other at one end, and the two sealing shafts (105) are in contact with each other at the other end.

5. A double damper fluoropolymer lined flue gas damper gate with sealed air according to claim 1, characterized in that: The sealing air connector includes a half-connecting pipe (3) and an exhaust control valve (4); a connecting groove (101) is provided at the upper end of the frame (1), and a half-connecting pipe (3) is fixedly connected to the upper end of the connecting groove (101) on the frame (1). The two half-connecting pipes (3) form a pipe body, and the exhaust control valve (4) is sealed and connected to the upper end of the two half-connecting pipes (3).

6. A double damper fluoropolymer lined flue gas damper gate with sealed air according to claim 1, characterized in that: After the two frames (1) are joined by flanges, the space at the end where the two sealing plates (107) are close to each other is the air chamber (6). The air chamber (6) is connected to each other through the connecting groove (101) and the two half-connecting pipes (3) that are joined into a pipeline.

7. A double damper fluoropolymer lined flue gas damper gate with sealed air according to claim 1, characterized in that: The outer side of the barrier plate (104) is lined with fluoroplastic sheet; the inner wall of the frame (1) and the sealing plate (107) are also lined with fluoroplastic sheet.
