Description

Technical Field

[0001] The utility model relates to the field of sealing structures, in particular to a novel and efficient combined tertiary air damper sealing device. Background Technique

[0002] The existing tertiary air damper sealing structure is a combined structure of a spring pressing mechanism and a graphite pressing block. Such a structure is adopted because the wind pressure at the damper is relatively large, and the spring pressing mechanism can provide a certain elastic margin. However, such a structure has certain defects. After being used for a long time, a relatively serious air leakage problem will occur, mainly because the pressure makes the edge of the tertiary air damper uneven. Therefore, in order to solve the above air leakage problem, it is necessary to further adjust and improve the existing sealing structure. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel and efficient combined tertiary air damper sealing device to solve the problem of serious air leakage in the existing tertiary air damper sealing structure.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A novel and efficient combined tertiary air damper sealing device includes a spring pressing mechanism, a sealing graphite block pressing block, and a box-type sealing mechanism. The spring pressing mechanism is evenly arranged around the tertiary air damper. The inner end of the spring pressing mechanism is connected to the sealing graphite block pressing block, and the box-type sealing mechanism surrounds the edge of the tertiary air damper and covers the outside of the sealing graphite block pressing block.

[0006] The original air leakage problem is caused by the deformation of the tertiary air damper and the elastic margin of the spring pressing mechanism. Therefore, a box-type sealing mechanism is added on the original basis. By covering the outside of the sealing graphite block pressing block with the box-type sealing mechanism, the gap where air leakage may occur between the sealing graphite block pressing block and the tertiary air damper is wrapped, and further sealing is carried out, so that the air leakage problem can be well solved.

[0007] As a further preference of the utility model, the spring pressing mechanism includes a fixing plate, a screw rod, and a spring. The fixing plate is arranged close to the tertiary air damper. The screw rod is horizontally inserted in the middle of the fixing plate. The inner end of the screw rod is connected to the outer end of the spring, and the inner end of the spring is connected to the sealing graphite block pressing block.

[0008] By rotating the screw rod, the pressing degree of the spring can be adjusted.

[0009] As a further preference of the utility model, the box-type sealing mechanism includes a box body and filled rock wool. The box body surrounds the edge of the tertiary air damper and covers the outside of the sealing graphite block pressing block, and the filled rock wool is filled in the box body.

[0010] The filled rock wool can block the air leakage gap and play a heat insulation role at the same time.

[0011] As a further preference of the present utility model, the box body includes a surrounding plate and a top plate. The inner end of the top plate is rotatably connected to the outer wall of the tertiary air damper, and a locking and sealing mechanism is provided between the outer end of the top plate and the outer end of the top surface of the surrounding plate.

[0012] The top plate can be opened to perform operations such as adding, removing, and replacing the filled rock wool in the box body.

[0013] As a further preference of the present utility model, a pulling and flipping mechanism is provided in the middle of the top surface of the top plate.

[0014] It is convenient to flip up the top plate.

[0015] Compared with the prior art, the present utility model can achieve at least one of the following beneficial effects:

[0016] 1. The original air leakage problem is caused by the deformation of the tertiary air damper and the elastic margin problem of the spring-type pressing mechanism. Therefore, a box-type sealing mechanism is added on the original basis. By covering the box-type sealing mechanism outside the sealing graphite block pressing block, the air leakage gap between the sealing graphite block pressing block and the tertiary air damper is wrapped, and further sealing is carried out, so that the air leakage problem can be well solved.

[0017] 2. The pressing degree of the spring can be adjusted by rotating the screw.

[0018] 3. The filled rock wool can block the air leakage gap and play a heat insulation role at the same time.

[0019] 4. The top plate can be opened to perform operations such as adding, removing, and replacing the filled rock wool in the box body. BRIEF DESCRIPTION OF THE DRAWINGS
