Description
Technical field
This utility model relates to a kind of large-scale batch mixing formula mechanical shaft kiln, a kind of large-scale batch mixing formula mechanical shaft kiln
The star-like discharging sealing device of kiln bottom.
Background technology
The kiln bottom discharging sealing device of large-scale batch mixing formula mechanical shaft kiln, need to keep ash discharge continuously, stable, safety, and protect
Card, under the positive pressure that kiln bottom is 10～30KPa, can play effective discharge lock wind effect, and in reducing kiln, air quantity is excessive, reduces
Dust in operating environment.Ash discharge water-tight equipment effect mainly has star ash hoist and two kinds of three road gates, star-like go out
Material sealing device with its simple in construction, easily fabricated, volume is little, become Chinese large-sized batch mixing formula mechanical shaft kiln use most
Kiln bottom discharging sealing device, the lump material of kiln bottom enters star-like discharging sealing device through elephant trunk, by lattice wheel rotor
Rotate and discharge, when lattice wheel rotor rotates, closely cooperate between lattice wheel rotor and housing, it is achieved the gas inside and outside shaft furnace is close
Envelope.
But star-like discharging sealing device the most often there arises a problem that one is to be sealed between end cap and rotating hub
Oil immersion asbestos packing, under worst hot case, packing is the most aging, abrasion, loses sealing function, causes the lock wind effect of ash hoist
Declining, even lost efficacy, two is that rotor rotational support position is immersed under environment at high-temperature material, kiln inner high voltage, dust, and grease is easy
Volatilization, high-temperature dust enters rotating hub axle and causes sliding bearing abrasion, sealing to be destroyed in the gap of sliding bearing.Above
2 reasons cause that ash hoist is difficult in maintenance, service life is short, and dust easily sprays, and affects site environment health.
Utility model content
For solve above-mentioned technical problem this utility model provide a kind of large-scale batch mixing formula mechanical shaft kiln kiln bottom star-like go out
Material sealing device, by the following technical solutions:
A kind of star-like discharging sealing device of large-scale batch mixing formula mechanical shaft kiln kiln bottom, including including axle, end cap, casing, put
Rotating hub in casing, rotating hub is connected with axle, and axle is connected with the end cap at body two ends by bearing positioning seat, and end cap passes through bolt
Fix with casing and be connected, be provided with rigid seal structure in rotating hub in end cap, the rotating hub fit clearance with casing inner surface.
Use this utility model of technique scheme compared with prior art, provide the benefit that:
Thoroughly solve oil immersion asbestos packing between ash hoist rotating hub and end cap the most aging, abrasion, lose sealing in a short time
The problem of effect；Service life length, environmental pollution is little, change with overhaul conveniently, low service work intensity low.
Further, prioritization scheme of the present utility model is:
Rigid seal be cross section be the circular ring structure of rectangle.
End cap is provided with the tapped through hole corresponding with rigid seal, adjusts bolt and coordinate with this tapped through hole.
Being provided with rolling bearing in bearing positioning seat, the annular boss of gland is pressed in the outer ring of this rolling bearing, and passes through
Connector is fixing with bearing positioning seat to be connected.
It is provided with the first outside framework oil seal structure in bearing positioning seat shoulder hole inside rolling bearing.
The round nut coordinated with axle it is provided with, the medial surface of this round nut and rolling bearing inner ring in the outside of rolling bearing
Lateral surface contact.
The second outside framework oil seal structure it is provided with in shoulder hole inside gland.
Tapped through hole and adjustment bolt are respectively set to multiple.
Accompanying drawing explanation
Fig. 1 is overall assembling schematic diagram of the present utility model.
Fig. 2 is bearing location seat structure schematic diagram of the present utility model.
In figure: axle 1；End cap 2；Casing 3；Rotating hub 4；Rigidity baffle ring 5；Adjust bolt 6；Bearing positioning seat 7；Fastening bolt 8；
First outside framework oil seal 9；Round nut 10；Gland 11；Bearing block 12；Bearing 13；Second outside framework oil seal 14.
Detailed description of the invention
In Fig. 1, the present embodiment includes that casing 3, rotating hub 4 are placed in casing 3, and rotating hub 4 is connected with axle 3, and axle 3 is positioned by bearing
Seat 7 is connected with end cap 2, and bearing positioning seat 7 plays the rotational support effect of countershaft 1；End cap 2 is connected with casing 3 by bolt,
Rotating hub 4 and end cap 2, casing 3 inner surface fit clearance in be provided with rigid seal baffle ring 5, seal, reduce kiln endogenous wind
Amount is revealed；End cap 2 is machined with seal stopper ring 5 corresponding section multiple tapped through hole, adjusts bolt 6 and join with tapped through hole
Close, after the end wear of rigid seal baffle ring 5, bolt 6 can be adjusted by regulation, reduce rigid seal baffle ring 5 and rotating hub 4
Gap between, continues up to sealing effectiveness.
In Fig. 2, being provided with rolling bearing 13 in the bearing positioning seat 7 of the present embodiment, the annular boss of gland 11 is pressed in rolling
The outer ring of dynamic bearing 13, positions rolling bearing 13, and is connected with bearing positioning seat 7 by fastening bolt；At rolling bearing 13
First outside framework oil seal 9 is installed in the bearing positioning seat shoulder hole of inner side, the second skeleton is installed in the shoulder hole inside gland 11
Oil sealing 14, prevents high-temperature gas from carrying dust secretly and enters rolling bearing 13 inside, can effectively prevent dust from 1 axle and rolling simultaneously
Bearing 13 gap location is excessive.Equipped with round nut 10 outside rolling bearing 13, round nut 10 coordinates with axle 1, round nut 10 interior
Side contacts with the lateral surface of rolling bearing 13 inner ring, and its effect is to prevent bearing positioning seat 7 from producing displacement with axle 1.Bearing is fixed
Rolling bearing 13 is positioned by position seat 7, plays support and precise positioning effect, thoroughly solves rotating hub shaft supporting part position and slides
Bearing maintenance maintenance difficulty, easily weares and teares, causes limekiln internal high temperature gas to carry flour dust overflow problem secretly, at rolling bearing 13
High temperature resistant outside framework oil seal is installed in both sides, prevents high-temperature gas from carrying dust secretly and enters rolling bearing 13 inside, causes rolling bearing 13
Damage, can effectively prevent dust excessive with rolling bearing 13 gap location from axle 1 simultaneously.
The foregoing is only the embodiment that this utility model is the most feasible, not thereby limit to power of the present utility model
Profit scope, the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, it is both contained in this utility model
Interest field within.
