Description
Technical field
The domestic waste incineration device of fire grate motion is the utility model is related to using Mechanical Driven and controls, more particularly to
Stoker fired grate support wheel sealing dust-proof device and the domestic waste incineration for equipping the device.
Background technology
Domestic waste is made burning disposal by prior art, has been universally acknowledged more excellent processing mode, burning disposal
House refuse can be made to obtain farthest " innoxious, recycling, minimizing " processing.In the prior art, consumer waste incineration
Processing equipment is generally exactly to equip the incinerator of stoker fired grate, although stoker fired grate is classified by its type of drive and the method for operation,
Including many kinds, but no matter which kind of type of furnace, its fire grate pushing structure and operation principle are all substantially the same, exactly use oil cylinder pushing
Zigzag moves beam and moved forward and backward so that many fire grate segments being sequentially stuck on the dynamic beam are also and then movable, and rubbish is in fire grate segment
On do not stop to stir burning, it is last all to turn to dust and ashes.Moved forward and backward to support the dynamic beam of the zigzag, multiple support wheels need to be set
Also referred to as roller, support wheel move beam with zigzag and move forward and backward and rotate, and effectively reduce the abrasion of dynamic beam, substantially prolongs life
The service life of waste incinerator living.
In the prior art, the support wheel of stoker fired grate, it is typically mounted on toward the incinerator air feed for equipping the stoker fired grate
In lower air chamber, the air compartment provides the First air that temperature is up to 220 DEG C for waste incineration, has quite a few after waste incineration
Tiny clinker is fallen in air compartment from fire grate segment, causes wind house dust larger, bad environments；Fig. 2 in Figure of description is
The orthographic projection partial schematic sectional view of prior art stoker fired grate support wheel, as seen from the figure bearing both ends do not set protectiveness portion
Part, therefore the dust in surrounding air without stopping can enter in bearing.Because the dust main component of waste incineration is stone
Sand, hardness are high, can cause bearing wear, even result in that roller is stuck motionless, have a strong impact on the normal operation of fire grate, and change
Support wheel wants blowing out to carry out, once and blowing out will result in heavy economic losses.Rubbish dust in burning drops, easily
In the self-lubricating bearing structure for invading support wheel, and the stoker fired grate of the domestic waste incineration can not be carried out again in operation
Maintenance, so as to cause many inconvenience for efficient, the safe operation of the house refuse.
The content of the invention
The technical problems to be solved in the utility model is, avoids above-mentioned prior art stoker fired grate support wheel bearing easy

The radial width outer ring portion of second sealing ring 160 is rabbeted in the second groove, and so as to stop in dust intrusion bearing, second is close
After seal ring 160 and pressure ring 180 install, pressure ring 180 can also be with the method for spot welding by pressure ring 180 and the company of fixation of bearing pin 310
Connect and be integral, while can also be connected between pressure ring 180 and gland 170 with the method for spot welding, when roller is support wheel
During 330 rotation, gland 170 and pressure ring 180 are and then rotated simultaneously, and by two road sealing devices, dust is blocked in bearing completely
Outside, reach the effect of sealing and dustproof.
Compared with the existing technology compared with the dust guard that stoker fired grate moves beam support wheel burns with the house refuse for equipping the device
Stove is burnt, including is symmetrically separately positioned on two glands of bearing and support wheel axial end portion；Bearing pin both ends radial surface set
Fill bearing, bearing outside surface suit support wheel, gland is sleeved on the axial more lateral of bearing pin radial surface, two glands and its
On the first sealing ring for setting bearing and support wheel are sealed from both ends respectively jointly, prevent dust from invading bearing, protect axle
Hold and extend its service life.A pressure ring is also respectively provided with the outside of two glands, pressure ring is sleeved on two on bearing pin respectively
The end of gland seals；Pressure ring and the second sealing for setting thereon play the protection of two level dust jointly by the end part seal of gland
Effect, while also play the effect that fixed support wheel avoids it from moving axially.Dust intrusion support wheel bearing is prevented to cause
Support wheel failure, extend service life of equipment, improve equipment complex efficiency of operation.
The obvious technical advantage that the utility model has compared with the prior art includes：1. the utility model is simple in construction, add
Work is easy, easy for installation, it is not necessary to maintenance and maintenance；2. under identical working environment, dust can be effectively prevented to invade bearing
It is interior, greatly reduce the abrasion of bearing；3. two sealing dust-proof devices are employed, it is simple in construction, it can effectively prevent dust from invading axle
In holding and prevent the lubricating grease in bearing from, toward external leakage, for a long time bearing can be kept to be run in the state of lubrication, reaching complete
The effect of sealing and dustproof, greatly prolong the service life of bearing;4. at present, no matter external fire grate introducing or domestic production is set
Standby, after its wheel device continuously runs half a year, bearing wear, which will reach 3~5mm, to be changed, once blowing out is changed, enterprise's meeting
Just into very big economic loss；And the utility model runs post-test-inspection more than a year by continuous, about 50 μm of bearing wear, press
This rate of wear calculates, bearing can normal use 5~6 years, the utility model effectively improves the mechanical performance of support wheel, not only
Extend the service life of equipment, reduce maintenance cost, and greatly improve the economic benefit of enterprise.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using utility model specification and accompanying drawing content, or directly or indirectly it is used in it
The technical field of his correlation, is similarly included in scope of patent protection of the present utility model.
