Description
Technical field
The present invention relates to drying grate field, especially a kind of drying grate support axis sealing structure of shaft end.
Background technique
Heat of the drying grate when being dried, preheating to pelletizing is provided by rotary kiln and ring cold machine, and heat is to pelletizing work
Skill plays the role of critical, all has an impact to the service life of pellet output and equipment, needs to guarantee chain in process of production
The leakproofness of comb machine avoids heat dissipation of leaking out, if leaking out heat dissipation, will lead to drying grate ambient temperature and increases to make to hold in the palm
Axle bearing damage；The sealing element installation of drying grate support axis shaft end is more troublesome at present, and due to being utilized in interior outside length
Bolted mode is connected and sealed, and bolt scaling loss is very fast in the case of a high temperature, and the sealing element of scaling loss butt axis shaft end is de-
It falls, is difficult to restore under barotropic condition, if restoring to want since the influence of design size, leakproofness are not achieved under negative pressure condition
It asks, brings many unfavorable effects to pelletizing production.
Summary of the invention
The technical problems to be solved by the present invention are: providing, a kind of dismounting is simple, replaces convenient drying grate support axis shaft end
Sealing structure, good airproof performance will not leak out heat dissipation.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: drying grate support axis sealing structure of shaft end, packet
Seal base, journal packing part and journal packing fastener are included, the seal base is two-half structure, and seal base is fixed on gear
On wall, asbestos are filled between seal base and barricade；Journal packing part be clipped between two half blocks of seal base and with sealing bottom
Plate is fixedly connected by screw；Journal packing fastener is with the columnar structured of flanging, journal packing fastener and journal packing
Part is connected together；Sealing ring resistant to high temperature is equipped between journal packing part and journal packing fastener.
Further, seal base is bolted with barricade, bolt welding is on barricade, the screw hole of seal base
Mouth is all cone ports.
Further, the sealing ring is metallic graphite carbon packing.
The beneficial effects of the present invention are: the seal base using two-half structure clamps journal packing part, structure dismounting
It is convenient, it is conveniently replaceable；Seal base is fixed by the bolt being welded on barricade with barricade, and will by the screw hole mouth of cone
Weld seam covers, and using asbestos as filling between the two, makes seamless fitting between seal base and barricade；Journal packing
Part and journal packing fastener are connected together, and are filled using sealing ring resistant to high temperature, good to the sealing effect of support axis, play to bearing
Protective effect.
Detailed description of the invention
Fig. 1 is shaft side figure of the invention；
Fig. 2 is front view of the invention；
In the figure, it is marked as 1- barricade, 2- seal base, 3- journal packing part, 4- journal packing fastener, 5- sealing ring.
Specific embodiment
To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, drying grate support axis sealing structure of shaft end of the present invention, including seal base 2, journal packing part 3
With journal packing fastener 4, the seal base 2 is two-half structure, and seal base 2 is fixed on barricade 1, seal base 2 with
Asbestos are filled between barricade 1；Journal packing part 3 is clipped between 2 two half blocks of seal base and is consolidated with seal base 2 by screw
Fixed connection, two-half structure, which facilitates, to be dismounted；Journal packing fastener 4 is with the columnar structured of flanging, and journal packing is buckled
Part 4 and journal packing part 3 are connected together；In order to further strengthen sealing effect, simultaneously because temperature is higher at barricade 1, in axis
It is equipped with sealing ring 5 resistant to high temperature between neck sealing element 3 and journal packing fastener 4, thermal loss can be effectively reduced, on the other hand
It can play the role of insulation blocking to support axis and bearing, prevent abrasion.
Seal base 2 is bolted with barricade 1, and bolt welding is on barricade 1, then barricade 1 and bolt fixation,
Seal base 2 is secured with nuts across bolt；Since bolt is welded on barricade 1, bolt necessarily has with 1 junction of barricade
Weld seam leaves, and weld seam can make to leave gap between the two when sealing baffle 2 and barricade 1 recline, and influences sealing effect, therefore will be close
The screw hole mouth of back cover plate 2 is set as cone ports, and when seal base 2 and barricade 1 recline, weld seam is embedded in cone ports, will not make close
There are gaps between back cover plate 2 and barricade 1.
Preferably, sealing ring 5 is metallic graphite carbon packing, and the heat resistance of metallic graphite carbon packing is strong, good airproof performance, is fitted
For high temperature, the environment of high pressure, and the hardness of graphite is not high, and quality is softer, can play good protection to support axis and bearing
Effect, be hardly damaged, service life it is long, can guarantee leakproofness for a long time.
Structure processing and fabricating of the invention is convenient, installation is simple, does not injure to apparatus body, does not also have to thermal process process
It adversely affects, moreover it is possible to reduce thermal loss and be conducive to improve the drying effect to pelletizing, can improve and produce ring around equipment
Border reduces environmental pollution, while optimizes production technology further.
