Abstract
The invention discloses a sealing structure for a shaft end of a supporting shaft of a grating machine. A sealing bottom plate is of a two-half type structure, and is fixedly arranged on a retaining wall; asbestos is arranged for filling between the sealing bottom plate and the retaining wall; a shaft neck sealing part is clamped between two half blocks of the sealing bottom plate, and is fixedly connected with the sealing bottom plate through a bolt; a shaft neck sealing fastener is a cylindrical structure with a folded edge, and the shaft neck sealing fastener is in blocking connection with the shaft neck sealing part; and a high-temperature-resistant sealing ring is arranged between the shaft neck sealing part and the shaft neck sealing fastener. The sealing bottom plate which is of the two-half type structure is adopted to clamp the shaft neck sealing part, so that the structure is convenient to dismount, and is convenient to replace; the sealing bottom plate is fixed with the retaining wall through the bolt welded on the retaining wall, and a conical screw hole covers a welding seam, and asbestos is arranged for filling between the sealing bottom plate and the retaining wall, so that the sealing bottom plate is in seamless fit to the retaining wall; and the shaft neck sealing part is in blocking connection with the shaft neck sealing fastener, the high-temperature-resistant sealing ring is utilized for filling, and the sealing effect on the supporting shaft is good, so that protection effect is achieved on a bearing.
Description
Technical field
The present invention relates to drying grate field, especially a kind of drying grate support axle sealing structure of shaft end.
Background technology
Heat of the drying grate when being dried to pelletizing, preheating is provided by rotary kiln and central cooler, and heat is to pelletizing work
Skill plays critical effect, and the service life of pellet output and equipment is all had an impact, and needs in process of production to ensure chain
The sealing of comb machine, it is to avoid radiating of leaking out, if leaking out radiating, can cause drying grate ambient temperature to raise so that support
Axle bearing is damaged；The sealing member of drying grate support axle shaft end is installed and is more bothered at present, and long due to being utilized in interior outside
Bolted mode is connected and sealed, and bolt scaling loss is very fast in the case of a high temperature, and the sealing member of scaling loss butt axle shaft end takes off
Fall, be difficult to recover under barotropic condition, can be due to the impact of design size if recovering under negative pressure condition, sealing is not reached will
Ask, many unfavorable effects are brought to pelletizing production.
The content of the invention
The technical problem to be solved is：One kind is provided and dismounts simple, the convenient drying grate support axle shaft end of replacing
Sealing structure, good airproof performance will not be leaked out radiating.
To solve above-mentioned technical problem the technical solution adopted in the present invention it is：Drying grate support axle sealing structure of shaft end, bag
Include seal base, journal packing part and journal packing fastener, the seal base is two halves formula structure, seal base is fixed on gear
On wall, asbestos between seal base and barricade, are filled；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；Resistant to elevated temperatures sealing ring is provided between journal packing part and journal packing fastener.
It is further：Seal base is bolted with barricade, bolt welding on barricade, the screw of seal base
Mouth is all cone ports.
It is further：The sealing ring is metallic graphite carbon packing.
The invention has the beneficial effects as follows：Journal packing part is clamped using the seal base of two halves formula structure, structure dismounting
It is convenient, it is conveniently replaceable；Seal base is fixed with barricade by the bolt being welded on barricade, and will by the screw mouth of cone
Weld seam is covered, and by the use of asbestos as filling between the two, makes seamless laminating between seal base and barricade；Journal packing
Part and journal packing fastener are connected together, and are filled using resistant to elevated temperatures sealing ring, the good sealing effect to holding in the palm axle, and bearing is played
Protective effect.
Description of the drawings
Fig. 1 is the shaft side figure of the present invention；
Fig. 2 is the front view of the present invention；
It is labeled as in figure：1- barricades, 2- seal bases, 3- journal packing parts, 4- journal packing fasteners, 5- sealing rings.
Specific embodiment
For the ease of understanding the present invention, below in conjunction with the accompanying drawings the present invention is further detailed.
As shown in Figure 1 and Figure 2, drying grate support axle 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 halves formula 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 solid by screw with seal base 2
Fixed to connect, two halves formula structure is conveniently dismounted；Journal packing fastener 4 is that, with the columnar structured of flanging, journal packing is buckled
Part 4 and journal packing part 3 are connected together；In order to further strengthen sealing effectiveness, simultaneously because temperature is higher at barricade 1, in axle
Resistant to elevated temperatures sealing ring 5 is provided between neck sealing member 3 and journal packing fastener 4, thermal loss can be effectively reduced, on the other hand
Can prevent abrasion from occurring to asking axle and bearing to play insulation blocking effect.
Seal base 2 is bolted with barricade 1, bolt welding on barricade 1, then barricade 1 and bolt fixation,
Seal base 2 is fixed through bolt with nut；As bolt is welded on barricade 1, bolt is necessarily had with 1 junction of barricade
Weld seam is stayed, and when sealing baffle 2 is reclined with barricade 1, weld seam can make to leave gap between the two, affects sealing effectiveness, therefore will be close
The screw mouth of back cover plate 2 is set to cone ports, when seal base 2 is reclined with barricade 1, in weld seam embedment cone ports, will not make close
There is gap between back cover plate 2 and barricade 1.
Preferably, sealing ring 5 is metallic graphite carbon packing, and the thermostability of metallic graphite carbon packing is strong, good airproof performance, fits
For high temperature, the environment of high pressure, and the hardness of graphite is not high, and quality is softer, can be to asking axle and bearing to play protection well
Effect, be hardly damaged, usage cycles it is long, sealing can be ensured for a long time.
Structure processing and fabricating of the invention is convenient, install simple, apparatus body is not injured, thermal process process is not had yet
Adversely affect, moreover it is possible to reduce thermal loss and be conducive to improving the drying effect to pelletizing, ring can be produced around improvement equipment
Border reduces environmental pollution, while making production technology further be optimized.
