Abstract

The utility model relates to a self-compensating wearproof elbow for pneumatic conveying. According to the technical scheme provided by the utility model, the wearproof elbow comprises an installation plate which is fixedly at the back of the elbow, a gap with equal thickness is formed between the installation plate and the back of the elbow, and a plurality of baffles are fixedly arranged between the installation plate and the external surface of the back of the elbow. The wearproof elbow has the advantages that the wear resistance is good, and compared with the existing elbow, the service life is improved by dozens of times; the wearproof elbow is convenient, labor-saving and material-saving to produce and use and the investment is small; and the application scope is wide and all materials can be pneumatically conveyed.

Description

Anti-wear elbow

Technical field

The utility model relates to the elbow that a kind of strength is carried, and is especially a kind of from the anti-wear elbow of reinforcing method.

Background technology

The wearing and tearing that prevent elbow are important problem in the Pneumatic conveyer.Existing prevent that elbow worn-down technical measures from mainly being:, mainly be to increase elbow worn-down thickness 1, for the elbow outer wall backplate of burn-oning in advance.2, be to use high-abrasive material (special cast iron and cast steel) to increase the service life.3, use tube wall to stud with the elbow that to change liner plate outward, change during wear liner.4, elbow is processed the square-section, outside tube wall, be lined with the liner plate that high-abrasive material is processed, also can adopt the dismounting and change structure, can change.

Suchlike method can only prolong the service life of some elbows, and has worn and torn and can change, and does not have the wear problem from basic solution elbow.Frequent replacing elbow also is to take a lot of work, take material, and trouble is many, and much the occasion elbow is all in the high-altitude, and it is also very inconvenient to change elbow.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the prior art, provides a kind of life-span can improve tens times, simple in structure and anti-wear elbow that range of use is wide.

The technical scheme that provides according to the utility model; Said anti-wear elbow; It is included in an adapter plate of the back fixation of elbow, forms the identical slit of thickness between the outside face at said adapter plate and elbow back, between the outside face at adapter plate and elbow back, is fixed with some baffle plates.

Said baffle plate is perpendicular to the axis of elbow inner chamber.

The utility model wear resisting property is good, improves tens times service life than existing elbow;

The utility model is made saving of labor easy to use, material-saving, small investment;

The utility model is applied widely, can use strength to carry (suction is sent, force feed) all materials (as: media such as dust, molding sand, cement).

Description of drawings

Fig. 1 is the integral structure scheme drawing of the utility model.

The specific embodiment

Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.

As shown in the figure: this anti-wear elbow; It is included in an adapter plate 1 of the back fixation of elbow 3; Form the identical slit of thickness between the outside face at said adapter plate 1 and elbow 3 backs, between the outside face at adapter plate 1 and elbow 3 backs, be fixed with some baffle plates 2.

Said baffle plate 2 is perpendicular to the axis 4 of elbow 3 inner chambers, and this axis 4 is the line in the center of circle in elbow 3 intracavity sections.

When strength convey materials operating mode, during material process elbow 3, partial material (dust, sand grains) is arranged; Owing to stopping of baffle plate 2, be trapped between two baffle plates 2 at elbow 3 back of a bow places, though constantly take away; But constantly replenish again, finally can form the protective cover that one deck is made up of material, the material bed mutual friction that the material bundle of motion only can and stop; Can the madial wall of adapter plate 1 not rubbed, this has just prolonged the service life of elbow 3 greatly.

The principle of the utility model is sent or force feed material high-speed motion in elbow 3 according to suction exactly; Its loss of pressure and transducer wall ' s abrasion are bigger; Has the characteristic that adhering fine dust very easily adheres to bend; Wittingly the real back of the body of baffled rectangle is made at elbow 3 backs (or being called bow portion), after elbow 3 back tube walls are worn out, let material or dust stop and form certain thickness protective cover at this place.Because the material that aerodynamic effect is stayed this place can be pulled away a part, but replenishing again afterwards.So constantly be pulled away, replenish, but always some is kept, and forms certain thickness material or dust layer, can the not wear and tear bow portion of elbow of the material that makes conveying and dust has so just fundamentally solved the wearing and tearing difficult problem of elbow.

Claims (2)

1. anti-wear elbow; It is characterized in that: it is included in an adapter plate (1) of the back fixation of elbow; Form the identical slit of thickness between the outside face at said adapter plate (1) and elbow back, between the outside face at adapter plate (1) and elbow back, be fixed with some baffle plates (2).

2. anti-wear elbow as claimed in claim 1 is characterized in that: said baffle plate (2) is perpendicular to the axis of elbow inner chamber.
