Description
Technical field
The utility model is related to kneader technical fields, and in particular to a kind of kneader paddle shaft.
Background technology
Chemical material is inevitably present heating, the technological problems such as cooling in production.General solution is cylinder body
Chuck is done to reach this purpose, but this is solved without very perfect scheme as paddle shaft the most frequent is contacted with material in outside
Problem.
As shown in Figure 1, existing frequently-used structure is paddle shaft hollow type, there are the following problems during use：(1) due to paddle
Axis is hollow, therefore paddle shaft intensity and rigidity decline to a great extent.Necessary performance parameter when to reach stirring, so the paddle shaft size of structure
Than conventional paddle shaft bigger；(2) it is to avoid paddle shaft indeformable in process of production, wall thickness will reach certain thickness, but wall thickness
Increase the decline for inevitably resulting in heat transference efficiency again, no matter heats or cooling is all extremely difficult to the estimated effect designed
Fruit；(3) paddle shaft hollow structure requires the casting technique of paddle shaft very high, it is difficult to the defects of avoiding the slag inclusion of hollow space, stomata,
Pipeline is heated or cooled easily to block；(4) because structure thus uses through type, therefore the power end axle portion of paddle shaft rotation has center
Hole, this weakens the intensity of paddle shaft again.
Utility model content
The utility model provides a kind of kneader paddle shaft, and heating or cold is improved under the premise of not increasing conventional paddle shaft size
But effect.
A kind of technical solution of kneader paddle shaft of the utility model includes：
Solid paddle shaft main body and enclosing element；
One end of the solid paddle shaft main body is equipped with trepanning, and the outer wall of the solid paddle shaft main body is equipped with empty slot；
The enclosing element coats the solid paddle shaft main body, and the trepanning, empty slot and the inner wall composition of the enclosing element are situated between
Matter inflow and outflow circulation canal.
Preferably, the both ends of the solid paddle shaft main body are respectively equipped with rotary joint, the center of two rotary joints
Line is located along the same line.
Preferably, symmetrical structure centered on the solid paddle shaft main body.
Preferably, the empty slot continuously setting or interval setting.
It is using the advantageous effect of above-mentioned technical proposal：
Since the kneader paddle shaft in the utility model uses solid paddle shaft main body, stirring intensity do not weaken, by
Empty slot, the inner wall composition medium inflow and outflow cycle of trepanning, empty slot and enclosing element are directly cut or cast out in solid paddle shaft main body
Channel increases substantially the heat exchanger effectiveness between medium and material in the case where not destroying paddle shaft intensity, to material
Quality, which provides, preferably to be ensured.In addition, the kneader paddle shaft in the utility model is directly restructured using conventional paddle shaft, without increasing
Paddle shaft size is also not required to remake casting wooden model, and features simple structure is easy.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific implementation mode
The utility model provides a kind of kneader paddle shaft, and heating or cold is improved under the premise of not increasing conventional paddle shaft size
But effect.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figures 2 to 4, a kind of technical solution of kneader paddle shaft of the utility model includes：
Solid paddle shaft main body 1 and enclosing element 2；
One end of the solid paddle shaft main body 1 is equipped with trepanning, and the outer wall of the solid paddle shaft main body 1 is equipped with empty slot；
The enclosing element 2 coats the solid paddle shaft main body 1, and the trepanning, empty slot and the inner wall of the enclosing element 2 form
Medium inflow and outflow circulation canal.
Preferably, the both ends of the solid paddle shaft main body 1 are respectively equipped with rotary joint, the center of two rotary joints
Line is located along the same line.
Preferably, symmetrical structure centered on the solid paddle shaft main body 1.
Preferably, the empty slot continuously setting or interval setting.
It is using the advantageous effect of above-mentioned technical proposal：
Due to the kneader paddle shaft in the utility model use solid paddle shaft main body 1, stirring intensity does not weaken, by
Empty slot is directly cut or cast out in solid paddle shaft main body 1, and the inner wall composition medium inflow and outflow of trepanning, empty slot and enclosing element 2 follows
Ring channel increases substantially the heat exchanger effectiveness between medium and material in the case where not destroying paddle shaft intensity, to material
Quality provide preferably ensure.In addition, the kneader paddle shaft in the utility model is directly restructured using conventional paddle shaft, without increasing
Add paddle shaft size, is also not required to remake casting wooden model, features simple structure is easy.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
