In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a sealed cavity mechanism of axle head of two-way seal, includes the door frame, the inside fixed mounting of door frame has the sealed cavity of second axle end filler device, the sealed cavity of second axle end right side fixedly connected with axle head, the sealed cavity right side fixedly connected with of axle head first axle end filler device, the inside door axle that is provided with of door frame.
Preferably, the second axial end packing device is connected with the axial end sealing chamber.
By adopting the technical scheme, the second shaft end packing device is connected with the shaft end sealing chamber, so that the left side of the shaft end sealing chamber is filled by the second shaft end packing device, and the tightness of the shaft end sealing chamber is improved.
Preferably, the shaft end sealing chamber is connected with the first shaft end packing device.
By adopting the technical scheme, the first shaft end filling device is arranged to be communicated with the shaft end sealing cavity, so that the right side of the shaft end sealing cavity is filled with the first shaft end filling device, and the tightness of the shaft end sealing cavity is greatly improved.
Preferably, the door shaft is movably attached to the outer surface of the inner wall of the door frame.
By adopting the technical scheme, the door shaft is movably attached to the outer surface of the inner wall of the door frame, so that the door shaft can drive the door plate to rotate around the door frame.
Compared with the prior art, the utility model has the beneficial effects that:
this two-way sealed axle head seal chamber mechanism, through the inside fixed mounting of door frame second shaft end packing device, second shaft end right side fixedly connected with axle head seal chamber, axle head seal chamber right side fixedly connected with first axle end packing device, the inside door axle that is provided with of door frame, no longer be direct intercommunication between axle head seal chamber and the door frame, separate two through axle head packing device, the sealed chamber of axle head to sealed fan section has accomplished the protection to a certain extent, even seal the wind system trouble, also can not cause the interior high temperature gas of flue to flow backward to the sealed chamber inside, two-way sealed packing device, both cut off the inside and sealed chamber of door frame, also cut off sealed chamber and door frame outside, greatly reduced the interior high temperature gas of flue from the possibility that axle head leaked, even seal wind system trouble, the interior high temperature gas of flue also can not directly get into sealed chamber, can effectively protect sealed chamber and sealed fan, thereby reach and solved high temperature gas and get into sealed chamber, can cause corrosion and wearing and abrasion to a certain extent to sealed fan, also can cause the condition that corrodes and damages to sealed fan to sealed chamber even.
Drawings
FIG. 1 is an enlarged cross-sectional schematic view of the present utility model.
In the figure: 1. a door frame; 2. the shaft end seals the cavity; 3. a first shaft end packing device; 4. a door spindle; 5. and a second shaft end packing device.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 in combination, when the utility model is used, in order to solve the problems that high-temperature gas can cause corrosion and abrasion to a certain extent to sealing filler and reduce the service life of the sealing filler, and also can cause corrosion and damage to a certain extent to a sealing chamber and even a sealing fan, the utility model relates to a shaft end sealing chamber 2 mechanism which comprises a door frame 1, wherein a second shaft end filler device 5 is fixedly arranged in the door frame 1, the right side of the second shaft end is fixedly connected with a shaft end sealing chamber 2, the right side of the shaft end sealing chamber 2 is fixedly connected with a first shaft end filler device 3, and a door shaft 4 is arranged in the door frame 1.
