Description
Technical Field
The utility model relates to the field of mechanical sealing, in particular to a door shaft sealing assembly.
Background
The door shaft sealing filler position of air door is usually nearer to the door frame, and when the heat preservation is installed to the flue gas duct outside, can wrap up filler device below the heat preservation for it is comparatively complicated to change door shaft sealing, need demolish partial heat preservation earlier, just can change the door shaft packing smoothly afterwards, and the bearing frame of current design is nearer to the door frame equally, and the inside temperature of flue gas duct majority condition is higher, also has higher temperature near the heat preservation outside, is in high temperature environment for a long time, can reduce bearing life.
What is needed is a door shaft seal that can replace the sealing filler without removing the insulating layer, effectively improve the working environment of the bearing seat, and extend the service life of the bearing seat to solve the above-mentioned technical problems.
Disclosure of Invention
In order to solve the problems, the utility model provides the door shaft sealing assembly, which can replace sealing filler on the premise of not dismantling the heat insulation layer, effectively improve the working environment of the bearing seat and prolong the service life of the bearing seat.
The utility model solves the technical problems through the following technical scheme:
the utility model provides a door shaft sealing assembly which comprises a door frame, a door shaft, a sleeve, a packing seat, a packing gland and a graphite packing; the sleeve is sleeved on the outer wall of the door shaft, and the lower end of the sleeve is fixed on the upper edge of the door frame; the upper end of the sleeve is fixedly connected with the packing seat, the graphite packing is arranged in the packing seat, and the packing gland is fixed at the top end of the packing seat; the packing gland and the packing seat are arranged on the outer wall of the door shaft and are in sealing combination with the door shaft through a graphite packing; a gap is maintained between the middle part of the sleeve and the outer wall of the door shaft.
In the utility model, the sleeve is a core component of the door shaft sealing assembly, so that a sufficient safety distance exists between the installation position of the filler seat and the smoke duct, and the replacement of sealing filler of the door shaft can be facilitated;
preferably, the bottom end of the sleeve is connected with a fixing plate, and the fixing plate is fixed at the upper end of the door frame.
In the utility model, the packing seat, the packing gland and the graphite packing are used for realizing the sealing of the door shaft;
preferably, the packing gland and the packing seat are fixed through stud bolts and nuts;
preferably, the sealing combination is ensured between the packing gland and the packing seat and between the packing seat and the door shaft through a graphite packing.
The sleeve can enable the installation position of the filler seat to be positioned outside the smoke air flue heat insulation layer; in the prior art, if the filler seat is required to be installed outside the heat insulation layer, the general measure is to simply increase the length of the filler seat, and correspondingly, the number of fillers is required to be increased, so that the production and manufacturing cost is increased, the rotating friction force of the door shaft is also increased, and the opening and closing of the air door are required to be more thrust.
The utility model has the positive progress effects that: the door shaft sealing assembly can replace sealing filler on the premise of not removing the heat insulation layer, effectively improve the working environment of the bearing seat and prolong the service life of the bearing seat.

Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1, the present embodiment provides a door shaft sealing assembly, which comprises a door frame 1, a door shaft 2, a sleeve 3, a packing seat 4, a packing gland 5 and a graphite packing 7; the sleeve 3 is sleeved on the outer wall of the door shaft 2, and the lower end of the sleeve 3 is fixed on the upper edge of the door frame 1; the upper end of the sleeve 3 is fixedly connected with the packing seat 4, the graphite packing 7 is arranged in the packing seat 4, and the packing gland 5 is fixed at the top end of the packing seat 4; the packing gland 5 and the packing seat 4 are arranged on the outer wall of the door shaft 2 and are in sealing combination with the door shaft 2 through graphite packing; a gap is kept between the middle part of the sleeve 3 and the outer wall of the door spindle 2, wherein the broken line part shows the height of the heat insulation layer.
In the embodiment, the sleeve 3 is a core component of the door shaft sealing assembly of the embodiment, so that a sufficient safety distance exists between the installation position of the filler seat 4 and the smoke duct, and the replacement of sealing filler of the door shaft 2 can be facilitated; the bottom of sleeve 3 is connected with fixed plate 8, and fixed plate 8 is fixed in the upper end of door frame 1.
