Abstract
A mechanical seal device of a gas-making furnace secondary closed furnace bar machine vertical shaft output end comprises a volute, a volute cover, a vertical shaft, a shaft section seal ring, a cone section seal ring and a driving gear. The mechanical seal device is characterized in that the shaft section seal ring is a graphite packing die-cast formation body and is provided with a radial notch groove, a semi-circle groove is formed on the outer circle of the shaft section seal ring, and an annular extension spring ring is attached inside the semi-circle groove in an elastic mode. The cone section seal ring is also a graphite packing die-cast formation body, an annular disc-shaped end face seal ring is attached between upper surface of the volute and the lower surface of the driving gear in an elastic compression mode, the end face seal ring is a graphite packing die-cast formation body, the diameter of the outer circle of the end face seal ring is the same as the outer diameter of a stage disc of the volute cover, the inner circle of the end face seal ring corresponds to the conical hole shape of the outer circle of the vertical shaft on the section, and an annular groove which corresponds to the annular circle protruded ring of the volute cover, is provided with an downward opening, and is arranged on the lower end face of the end face seal ring, is sleeved on the annular circle protruded ring of the volute cover. The mechanical seal device has the advantages that the three-seal-ring compression type is utilized, elastic, axial and radial seal effects are good, mechanical seal is conducted on the vertical shaft, and leakage is avoided.
Description
technical field:
The present invention relates to ammonia stove accessory, particularly the mechanical seal device of gas producing furnace two generation enclosed grate mechanism vertical shaft output terminal.
background technique:
Synthetic ammonia two generation enclosed fire bars machine is positioned at stove furnace hearth, drives furnace bottom outline ball mechanism to rotate thus got rid of smoothly by furnace bottom lime-ash after the rotation of drive ash-pan by it.Grate mechanism is made up of motor, worm gear pair, driving gear.The vertical shaft output terminal mechanical seal device of worm gear pair is made up of spiral case, snail lid, vertical shaft, shaft part seal ring, cone section seal ring.Snail lid cylindrical is that two-way step is discoid, its lower dome ring fit is fixed in spiral case upper end-hole, it is poroid that snail lid inner circle is three grades of steps, engagement sleeves is moved on vertical shaft cylindrical in hole of getting out of a predicament or an embarrassing situation, shaft part seal ring is provided with between middle step hole and vertical shaft cylindrical, top bar hole and vertical shaft is bored to be provided with between shell of column and is bored section seal ring, and two sections of seal rings revolve filling compacting with graphite packing cheese respectively; Snail covers surface and is provided with ring week bulge loop, and the driving gear lower surface that all bulge loops of ring and vertical shaft axle head are fixed possesses small―gap suture, and the bulge loop effect of ring week is the lime-ash blocking gasifier bottom, prevents lime-ash from invading seal ring.If do not stay small―gap suture and driving gear veneer, then hinder pinion rotation, after two seal rings and vertical shaft cylindrical wear and tear, also can produce gap.
This seal form is in gasifier bottom because equipment runs, in the rugged environment such as high-temperature ash, high-temperature vapor, the operation about one month of original material filling type machinery envelope just starts to lose efficacy, being subject to coal ash ground-slag after the wearing and tearing of shaft part seal ring inner circle immerse, there is coal ash ground-slag and immerses passage in the small―gap suture that the driving gear lower surface that all bulge loops of former ring and vertical shaft axle head are fixed is possessed.A large amount of water vapors and coal ash ground-slag enter grate mechanism inside by the machinery envelope lost efficacy, and the bearing of grate mechanism inside, worm screw turbine are damaged, cause grate mechanism be working life individual month of 2-4 not etc.Replacing maintenance grate mechanism stops gas producing furnace production consumption and significantly rises.
summary of the invention:
The object of the invention is to overcome above-mentioned defect, a kind of mechanical seal device of gas producing furnace two generation enclosed grate mechanism vertical shaft output terminal is provided.
The solution of the present invention is: comprise spiral case, snail lid, vertical shaft, shaft part seal ring, cone section seal ring, also comprise driving gear, it is characterized in that: shaft part seal ring is graphite packing die cast body, shaft part seal ring is provided with radial indentation groove, shaft part seal ring with outer is provided with half slot, all extension spring circles of elastic fit one ring in half slot; Cone section seal ring is also graphite packing die cast body; Cover elasticity pressure type between surface and driving gear lower surface snail to fit the end-face seal ring of an annulus plate-like, end-face seal ring is graphite packing die cast body, it is isometrical that its cylindrical and snail cover step disk external diameter, its inner circle is the taper hole shape corresponding to this section of vertical shaft cylindrical, and the downward opening ring week groove corresponding to snail bezel ring, week bulge loop that its lower end surface is arranged is linked on snail bezel ring, week bulge loop.
The invention has the advantages that: three seal ring pressure type elastic packings, axially, radial seal is effective, realize two generation enclosed grate mechanism vertical shaft machinery envelope do not leak, long-play.

embodiment:
The present invention includes spiral case, snail lid 3, vertical shaft 6, shaft part seal ring 5, cone section seal ring 2, also comprise driving gear 1, it is characterized in that: shaft part seal ring 5 is graphite packing die cast body, shaft part seal ring 5 is provided with radial indentation groove, shaft part seal ring 5 cylindrical is provided with half slot, all extension spring circles of elastic fit one ring in half slot; Cone section seal ring 2 is also graphite packing die cast body; Between snail lid 3 upper surface and driving gear 1 lower surface, elasticity pressure type is fitted the end-face seal ring 7 of an annulus plate-like, end-face seal ring 7 is graphite packing die cast body, its cylindrical and snail lid 3 disk external diameter of topping bar is isometrical, its inner circle is the taper hole shape corresponding to this section of vertical shaft 6 cylindrical, and the downward opening ring week groove corresponding to snail lid 3 ring week bulge loop that its lower end surface is arranged is linked on snail lid 3 ring week bulge loop.
Shaft part seal ring 5 is provided with all extension spring circles of ring and radial indentation, and after inner circle wearing and tearing under elastic force effect, its inner circle can hold vertical shaft tightly by auto-necking.
End-face seal ring 7 material has intrinsic elasticity, upper-end surface and driving gear 1 lower surface elastic fit, and lower end surface is with snail lid 3 ring week bulge loop location, and graphite material is wear-resisting and friction factor is little, has sealed the intrusion of lime-ash, high-temperature steam after Double End laminating completely.After shaft part seal ring 5, the wearing and tearing of cone section seal ring 2 inner circle, the extruding of end-face seal ring 7 elasticity downforce can be subject to and automatically shrink inner circle, good sealing effect.
