The publication is 2022.01.13 Chinese patent discloses a pipeline through-wall hole fills sealing mechanism for building water supply and drainage, including the wall body, set up the through-wall hole on the wall body and run through in the pipeline of through-wall hole, the pipeline outside just is located the both sides of wall body and all is equipped with annular hole sealing plate in the suit, two hole sealing plate nest respectively at through-wall hole both ends, and two through the long screw pole fixed connection of symmetric distribution between the hole sealing plate, the supporting ring has just been cup jointed to the symmetry in the pipeline outside and in the through-wall hole, the supporting ring outside symmetry is connected with the reinforcement piece, just long screw pole runs through in the reinforcement piece side, adopts hole sealing plate shutoff between pipeline and the wall body in this patent, fills with the through-wall hole between the filler because the drive shaft is the needs to rotate, and hole sealing plate and wall body structure are unreasonable, consequently can not adopt the form of filling the filler, and hot air can be along with the gap blowout drying chamber, leads to the outdoor wallboard to be in the long-term high temperature state colour change influence life.

Disclosure of Invention

The utility model provides a drying chamber hole sealing component for solving the problems that a sealing device and a drying chamber wall are unreasonable in sealing structure, hot air leaks outwards and the service life of the drying chamber wall is influenced.

The technical scheme adopted by the utility model for achieving the technical effects is as follows: the utility model provides a drying chamber hole seal assembly, includes the flange sleeve pipe, and flange sleeve pipe center passes there is the drive shaft, and the flange sleeve pipe includes flange, and flange right side is provided with the sleeve pipe, and the sleeve pipe passes the drying chamber wall body, flange fixed connection in drying chamber wall outer wall board, flange left side is connected with movable flange, is provided with the rubber pad between flange and the movable flange, and the sleeve pipe is connected with the drying chamber wall body full weld. The sleeve pipe is connected with the drying chamber wall body in a full-welded mode to block gaps between the sleeve pipe and the drying chamber wall body, hot air cannot be blown out from the gaps between the sleeve pipe and the drying chamber wall body, the sleeve pipe and the driving shaft are sealed by the fixing flange and the rubber pad, and hot air cannot be blown out from the gaps between the driving shaft and the sleeve pipe.

Further, the diameter of the middle opening of the rubber pad is the same as that of the driving shaft. The middle of the rubber pad passes through the driving shaft, and hot air with the same diameter as the driving shaft in the rubber pad opening hole cannot be blown out from a gap between the driving shaft and the sleeve.

Further, the fixing flange is connected with the outer wall plate of the drying chamber wall by rivets. The rivet connection is quick and convenient, and the flange sleeve can be replaced in time when damaged.

Further, the fixed flange and the movable flange are connected through bolts. The fixed flange and the movable flange are connected through bolts, so that the rubber pad is convenient to replace.

Further, the fixed flange and the movable flange are consistent in size.

Further, the rubber pad adopts a high-temperature-resistant rubber sealing gasket. The high-temperature-resistant rubber sealing gasket can prevent the rubber gasket from being damaged by hot air, and the service life is prolonged.

From the above technical scheme, the utility model has the following technical effects: the sleeve pipe and the drying chamber wall body adopt full-welded connection to fill up sleeve pipe and drying chamber wall body gap, and the sealing gasket shelters from the gap between drive shaft and the sleeve pipe, and hot air can not blow out from the sealing chamber hole, and the stoving effect in the drying chamber can not receive the influence because of hot air is blown outward.
