Description
Technical field
A kind of extruder is the utility model is related to, particularly a kind of helical vacuum extruder.
Background technology
New and effective helical vacuum extrusion shaping machine is a kind of large scale equipment, in conventional mounting mode, motor installation bottom
Frame is separately installed with main body, and the distance and locality of Chang Yinwei installations have deviation to cause driving belt installation question, particularly
When overload and impact, the influence at position is coupled to machine.New and effective helical vacuum extrusion shaping machine is one of complete set of equipments
Point, in production scene because the influence maintenance main shaft seal position of its auxiliary equipment is very difficult, former main shaft sealing construction is in reality
In use, because the thing that bad seals cause the raw material of extrusion shaping machine to enter bearing chamber damage bearing often has generation.If
Using vacuum extruding technique, except raw material can enter bearing chamber after sealing (oil sealing) destruction, the negative pressure of vacuum chamber can take bearing away
The lubricating oil of room causes bearing heating, locking, and vacuum-extruder bad seals can make the vacuum degradation of vacuum chamber, even if
Whole main shaft portion can must be also pulled down when early detection problem is in maintenance（Containing bearing chamber）, dismantle bearing and check whether there is production
The foreign matters such as product raw material enter bearing, whether bearing has damage（Actual conditions are that have more than 80 percent damage to change）, change
Seal of damage etc., because it is to be isolated with oil sealing, sealed that helical vacuum brick extruding, which (goes out) vacuum (raw material) room of machine with bearing chamber,
's.The too high too fast failure that can mean that sealing of base bearing temperature rise occurs in routine use, while this seal failure early stage
It is not easy to find to confirm.Etc. will dismount whole main shaft portion after pinpointing the problems, and change oil sealing, check bearing, whole maintenance
Process is all worked continuously, and repairing workload is very big, or even occurs causing kiln to burn without product because can not repair in time
And situation about stopping production.
Existing bearing chamber structure is as follows：(bearing cup is joined with bolts bearing cup with feed chamber by sealing, and two fix
Packed O-ring is filled between face), self-aligning thrust roller bearing (self-aligning thrust roller bearing in the bearing cup, cycle surface
Cover ＞ on ＜ bottoms after being fixed on bearing cup, inner ring is fixed on axle), spacer sleeve (spacer sleeve be fixed on axle and be stuck in left and right
Between two bearings, both ends of the surface, which are withstood on two bearings inner ring, ensures that two bearings are separated by a distance), self-aligning roller bearing（This bearing
Outer ring is fixed in bearing cup, and inner ring is withstood on the end face of axle sleeve mounted in end face top spacer sleeve other end on axle）, axle sleeve
(axle sleeve is fixed on axle on axle and is connected positioning with axle sleeve with a flat key, and both ends of the surface withstand on self-aligning roller bearing inner ring and labyrinth respectively
On Moving plate end face, the O-ring equipped with sealing ensures the sealing of main shaft and shaft room on axle sleeve), the quiet disk in labyrinth（Work as bearing cap again
With）（The quiet disk in labyrinth is fixed by bolts on the step of bearing cup end face and sealed between two stationary planes with O-ring, the quiet disk one in labyrinth
End boss loads the outer ring positioning that bearing cup is used for doing self-aligning roller bearing, has maze trough to coordinate shape with dynamic labyrinth on other end
Into labyrinth seal, the quiet disk endoporus in labyrinth is a boss hole, and hole is built with 3 lip-type packings, lip-type packing lip and axle sleeve
Outer ring cooperatively forms sealing）.By above-mentioned part mating connection composition bearing chamber, it is integrally attached to new and effective helical vacuum
On the vacuum chamber of extrusion shaping machine（Vacuum chamber is a sealed environment that can form negative pressure）Vacuum tank after being connected with bearing chamber
Physical efficiency meets under certain condition to the seal isolation of water, oil, gas outside case.

The bad lip-type packing that need to only change on prime closure and felt collar become light maintenance by overhaul, with the damage being that of avoiding to bearing
It is bad.The vacuum sealing changed on damage prime closure is much more convenient and simple than maintenance replacing bearing, and changes the true of damage
Bearing seal can also be checked, be changed during empty seal.The utility model is greatly reduced loss, and maintenance time is most
Shorten percentage 80 less, improve the service efficiency of equipment.
2. the mud breaker and tapered sleeve described in the utility model are to improve its structure on the basis of original, broken mud originally
Cutter spacing is in higher level's material receiving box body outside tapered sleeve, and mud breaker leaf length is longer because not long can turn over mud and length from mud breaker periphery
Go out part wears it is small among abrasion is big occur among the mud breaker that grows of situation about rubbing fall into subordinate and will damage subordinate's spiral, original
Mud breaker can not be positioned in tapered sleeve, and the utility model is by changing structure and tapered sleeve and the mud breaker position of tapered sleeve and mud breaker
Relation, prevent pug from turning up agglomerating, broken mud is uniform, and the pug overwhelming majority is not produced with higher level's material receiving box and contacted, and stifled vacuum occurs
And the probability of roof fall is very low, original pug regulation can be instead of to adjust the inlet of pug by increasing and decreasing mud breaker quantity
Flange, pug segmentation are uniformly more conducive to extract the air in pug, while the mud bar compactness of favourable subsequent processing extrusion forming out
More it is high evenly, finally out brick better quality.Prevent pug from splashing, make vaccum-pumping equipment service life longer, save
Maintenance cost.
3. forming one in the utility model between prime closure, axle sleeve, bearing cap and bearing cup can airtight chamber.Axle
The observation control device that bearing cup is provided with can reflect the sealability of prime closure vacuum seal, and can be according to the big of gas leakage
Small, vacuum seal both sides pressure differences, judge that the working condition of vacuum seal provides foundation to maintenance time.On bearing cup
Valve is closed（Under normal circumstances can be normally opened）When its chamber communicated can form annular seal space, prime seal cap sealing damage can not
In the case of normal production, this valve can be closed and establish the secondary seal guarantee of relative vacuum casing very using the sealing of bearing cap
The pressure of empty van body makees emergent production, avoids because maintenance radiography rings yield.The oil filling device of prime closure independence is determined
When refuel and ensure the relative clean of vacuum seal lubricating oil, the warranty life of seal can be extended.
