Abstract
The utility model discloses a wear -resisting elbow of cement conveyer pipe, it includes the elbow and sets up in the casing of elbow periphery, the casing intussuseption be filled with the concrete, the bellied block ring of elbow internal surface equipartition multichannel, block ring and elbow internal surface be continuous full weld and couple. The utility model has the advantages of stand wear and tear, shock resistance, long service life and reduced the change frequency of elbow.
Description
Technical field
The utility model relates to a kind of wear-resistant bend of cement pipe.
Background technology
On the bulk cement transfer pipeline of current domestic dry method powder delivery system and building material industry, its pipelineElbow or bend pipe that turning adopts wear resistant cast iron or cast steel to manufacture conventionally, at the wear-resisting material of internal spray of elbowMaterial, or adopt hemispherical elbow, all to work continuously but the gas of powder is defeated, elbow is subject to rushing containing powder air-flowBrush, impaired serious, and at turning easy sedimentating dust, shorten service life, and increase maintenance capacity,Reduce production efficiency, even cause dust to leak and contaminated environment.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of wear-resistant bend of cement pipe.
For achieving the above object, the technical solution adopted in the utility model is: it comprises elbow and is arranged at curvedThe housing of periphery, is filled with concrete in described housing, the uniform multiple tracks projection of described elbow inner surfaceBlock ring, described block ring is that continuous full weld connects with elbow inner surface.
The utlity model has following beneficial effect: the utlity model has wear-resistant, shock resistance, use longevityLife is long and reduced the advantage such as replacement frequency of elbow.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by rightIn embodiment or description of the Prior Art, the accompanying drawing of required use is briefly described, apparently, belowAccompanying drawing in description is only embodiment more of the present utility model, for those of ordinary skill in the art,Do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is only that the utility model part is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.
As shown in Figure 1, the utility model comprises elbow body 1 and is arranged at the housing 2 of elbow 1 periphery, described inHousing 2 in be filled with concrete 4, not only cost is low to adopt Concrete Filled, and has wear-resistant, anti-Impact, long service life and reduced the advantages such as the replacement frequency of elbow. Protruding in the uniform multiple tracks of elbow 1 inner surfaceThe block ring 3 rising; Described block ring 3 is that continuous full weld connects with elbow 1 inner surface. Wear-resistant bend and generalLogical elbow installation method is the same, is connected on pipeline by welding or flange. According to fluid flow feature, streamBody is main wearing and tearing block ring in flow process, after block ring has worn and torn, can again weld new block ring,Greatly extend the service life of elbow. At the block ring of the uniform multiple tracks projection of elbow inner surface, fluid is at bend pipeBlock ring place is repeatedly stagnated, and material particles produces herein and clashes into spring, collision mutually, has reduced materialImpact walls face velocity and material impacting angle, reduced the wearing and tearing to bend pipe wall, compared with common elbow, and the longevityLife increases several times, and manufacture craft is simple, replaceable after the built-in block ring wearing and tearing of elbow, extends BendableLife cycle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., allWithin should being included in protection domain of the present utility model.
