Description
Technical field
The present invention relates to a kind of xanthating machine blenders, belong to the production equipment technology of viscose rayon.
Background technique
Xanthating machine is the important equipment of chemical fibre viscose glue production, wherein xanthating machine blender is even more the core in xanthating machine
Part, blender are made of agitating shaft, size support arm, helical blade.During the work time, blender stirs viscose glue raw material
It mixes, bears biggish alternate torque load, each part bears different alternate stresses on blender.
Existing xanthating machine blender is made of the good Q345-B material of welding performance, mainly will by welding manner
Each part connects, and constitutes blender.Since xanthating machine agitator structure size is big, blender is without complete after general welding
The thorough stress relief annealing process in face, moreover, because the agitating shaft on blender is using seamless steel pipe and the knot of both ends plug
Configuration formula is dried set technique using heating between seamless steel pipe and plug and is attached, and does not also allow to carry out heating objectively and goes to answer
Power annealing dries set bonding strength in order to avoid reducing.So there is certain welding stress, or even welding in the welding section on blender
Defect, especially at agitating shaft and the support arm solder design near, since weld size is big, welding stress and welding defect are more
Obviously.
The long-term work of xanthating machine blender under alternation stress state, at agitating shaft and support arm solder design near
It is easy to happen fatigue rupture under the collective effect of welding defect and alternation stress, it is cracked on agitating shaft, and by
Flaring transforms into crack and causes to stir axle fracture, causes huge economic losses to enterprise.
Summary of the invention
The technical problem to be solved by the present invention is how to avoid the agitating shaft of xanthating machine blender that fatigue fracture occurs, prolong
Its long service life.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of xanthating machine blender, feature exists
In: including agitating shaft, support arm, helical blade three parts, support arm is mutually fixed by holding connection structure tightly with agitating shaft, spiral
Blade passes through connection structure and is aided with welding mutually to be fixed with support arm；
The agitating shaft includes hollow steel pipe and plug made of No. 45 steel or 40Cr material, hollow steel pipe both ends and stifled
Head dries set connection by heat；
The support arm includes supporting element and C clamp, and supporting element head is welded and fixed with the helical blade, supporting element root
Portion forms the semicircular structure of indent, and the semicircular structure of supporting element root and C clamp are held tightly on the agitating shaft, the two mistake
It is full of and is cooperatively connected and is fixed by screw.
Preferably, the hollow steel pipe and plug junction are equipped with the sealing weld seam welding structure through sanding and polishing.
Preferably, the installation site that support arm is corresponded on the agitating shaft is equipped with annular mounting recess.
It is highly preferred that rounding angle at the port of the annular mounting recess top edge.
It is highly preferred that the semicircular structure both ends of the supporting element root extend outward to form the first connection boss, first
It connects boss and is equipped with countersunk head through-hole；The C clamp both ends are equipped with the second connection boss, and the second connection boss is equipped with screw thread
Hole, the screw passes through the countersunk head through-hole on the first connection boss and the threaded hole connecting on boss with second is connected and fixed.
It is highly preferred that being coated with locking glue in the threaded hole.
It is highly preferred that the screw head in the countersunk head through-hole is welded with cover plate.
It is highly preferred that the annular mounting recess outer surface on the agitating shaft forms the first anti-rotational plane, the support
The semicircular structure inner surface of part root forms the second anti-rotational plane, and the C clamp inner surface forms the anti-rotational plane of third,
First anti-rotational plane and the anti-rotational plane of the second anti-rotational plane, third are fitted close, and keep supporting element and C clamp tightly fixed
Ensure not relatively rotate on agitating shaft, and through planar structure.
Preferably, the annular mounting recess junction both ends on agitating shaft are provided with the boss of bottom belt knuckle,
In the case where reducing stress concentration, ensure that support arm and agitating shaft do not slide axially from structure.
Preferably, the C clamp and supporting element connecting sewing groove are equipped with the welding structure of the smooth surface of sealing.
Preferably, the high-strength screw that the attachment screw is 8.8 grades or more.
Compared with prior art, xanthating machine blender provided by the invention has the following beneficial effects:
1, the agitating shaft of alternation load larger for receiving, material selection intensity and comprehensive performance are more compared with Q345-B
No. 45 high steel or 40Cr, improve agitating shaft structural strength；
2, the welding connecting mode for cancelling traditional agitating shaft and support arm keeps support arm and agitating shaft solid by interference fit
It connects, due to using non-solder structure in the biggish support arm of stress and stirring shaft connection place, avoids because welding defect is to Huang
What change machine agitating shaft intensity generated weakens the influence, and improves structural strength, extends the service life of equipment, and is not necessarily to after carrying out
Continuous heat treatment, simplifies manufacturing process, while avoiding since heat treatment goes welding stress to dry set to agitating shaft both ends plug heat
The influence of bonding strength；
3, the annular mounting recess and anti-rotational plane opened up on agitating shaft enhances blender at work from structure
The ability that support arm is resisted torsional deflection and axially slid.
4, pass through small weld seam welded seal at C clamp and supporting element connecting sewing, and face of weld is polished, it is ensured that entirely stir
Device surfacing is mixed, in order to which production process cleans yellow retained material.
