Abstract
The utility model relates to a wear-resisting ellipsoidal multiple-pass elbow. The utility model comprises an ellipsoidal body capable of forming a dust adhesive film on an inner wall, and an input through pipe and an output through pipe arranged on the ellipsoidal body. The utility model has the advantages of simple structure and long service life, and can be broadly applicable for pneumatic material conveying pipes.
Description
Affiliated technical field
The present invention relates to the how logical elbow of a kind of wear-resisting elliposoidal, can be widely used in the strength convey materials pipeline, especially be applied on the cement Pneumatic conveying pipeline of powder body, Building Materials Factory in the dry ash of power plant and heat supply center boiler and dried slag, chemical plant.
Background technology
At present, strength convey materials pipeline is subjected to the friction of compound, special on turn, and promptly the passage elbow of pipeline is subjected to washing away very easy to be worn out.Be this difficult problem of solution on the engineering, usually on the elbow of pipeline, adopt wear-resisting alloy steel or inner liner abrasive resistant material,, but still do not break away from of the direct impact of a solid gas mixture its inside face though this can prolong certain service life, efficient is not satisfactory, and involves great expense.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy to manufacture, how logical cost is low, the wear-resisting elliposoidal of long service life elbow.
In order to achieve the above object, how logical elbow comprises that inwall can form the ellipsoid body of dust adhesion layer to the wear-resisting elliposoidal of the present invention, the input siphunculus that is provided with on the ellipsoid body, output siphunculus.
The principle of work that the wear-resisting elliposoidal of the present invention is led to elbow more is: the present invention adopts the elliposoidal structure, has changed the technological process of a solid gas mixture, and when this compound flowed into the elliposoidal space of amplification suddenly from importing siphunculus, flow velocity reduced; When flowing to the output siphunculus again from the space of amplifying, flow velocity increases again, and in the big flowing space of sudden expansion, the two-phase fluid to a solid gas mixture must make solid phase be trapped in dead angle area, forms adhesion layer on inner wall surface.This adhesion layer just makes compound and elbow interior wall face keep apart, and plays buffer protection function, avoids a solid gas mixture to directly the washing away of elbow interior wall face, and elbow interior wall face resistance to abrasion strengthens greatly, and significantly improve service life.
The wear-resisting elliposoidal of the present invention is led to elbow more; the inwall dead band forms the dust adhesion layer; play protective effect, do not need to add in addition system inner liner metal high-abrasive material, simple in structure; easy to manufacture; so greatly reduce production costs, simultaneously, because elbow interior wall is not subjected to directly to wash away; the elbow that has the abrasion-resistant metal lining with existing inwall is compared, and also greatly improve service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation.
Fig. 1 is that wear-resisting elliposoidal is led to a kind of structural representation in the elbow more;
Fig. 2 is A among Fig. 1---the A cutaway view;
Fig. 3 is that wear-resisting elliposoidal is led to the another kind of structural representation in the elbow more;
Fig. 4 is B among Fig. 3---the B cutaway view.
The specific embodiment
In Fig. 1～Fig. 4, the wear-resisting elliposoidal of the present invention is led to elbow more, comprises that inwall can form the ellipsoid body 1 of dust adhesion layer, the input siphunculus 2 that is provided with on ellipsoid body 1, output siphunculus 3.
The wear-resisting elliposoidal of the present invention is led to elbow more, Gu a gas mixture flows to as shown by arrows, forms inwall adhesion layer 4.
The wear-resisting elliposoidal of the present invention is led to elbow more, and the middle part of ellipsoid body is a cylinder, and input siphunculus, output siphunculus join with various angles and cylinder, and the two ends of cylinder are spheroid-like, and how logical elbow can utilize the material monolithic casting to form to elliposoidal; Also available round steel pipe at both ends welding end socket, the welding straight tube is made at the middle part.
In strength convey materials system, remove load transfer device, also have delivery duct, on delivery duct, remove straight length, also have many logical elbows.
Claims (1)
1. a wear-resisting elliposoidal is led to elbow more, it is characterized in that comprising that inwall can form the ellipsoid body of dust adhesion layer, the input siphunculus that is provided with on the ellipsoid body, output siphunculus.
