Abstract
The utility model discloses a steel frame plastic composite tube with an abnormal inner layer, which comprises a steel frame, an adhesive resin layer wrapping the steel frame, an inner layer plastic tube and an outer layer plastic tube, wherein the inner layer plastic tube and the outer layer plastic tube are respectively arranged on the inner side and the outer side of the adhesive resin layer in composite mode. The thickness of one side of the wall of the inner layer plastic tube is thick, and the thickness of the other side of the wall is thin. The steel frame plastic composite tube with the abnormal inner layer has the advantages that when the steel frame plastic composite tube is used as a collecting and conveying pipeline of a sylvite basin, the wall thickness of one side of the composite tube is increased, thereby increasing abrasion quantity of the bottom of the pipeline, avoiding the phenomenon that pressure-bearing capacity of the pipeline is decreased due to quick abrasion of the bottom of the pipeline, and prolonging service life of the pipeline in multiplied mode.
Description
Technical field
The utility model relates to a kind of plastic composite pipe, is applicable to that ore pulp transports, and is meant the steel skeleton plastic clad pipe that a kind of internal layer is special-shaped especially.
Background technique
Steel skeleton plastic clad pipe is domestic in recent years emerging a kind of tubing; Its structure is that internal and external layer is plastics; The mesosphere is the Steel Skeleton enhancement layer; Adopt the special bonding resin that Steel Skeleton is mutually compound with the internal and external layer plastics, because of its particular structural, tubing have bearing capacity by force, advantage such as good corrosion resistance, wear-resisting property be good; Being widely used in fields such as urban construction, petrochemical industry, power communication, metallurgical mine and agricultural irrigation, is the best substitute products of conventional pipelines such as steel pipe, cast iron tube and cement pipe.
Though steel skeleton plastic clad pipe has good wear-resisting property than other conventional pipelines; But when gathering the conveyance conduit application, through pipeline mixed ore pulp is transported to processing factory on the bank earlier, because the sylvite particle is inhomogeneous as the sylvite salt pan; Larger particles is easy to be deposited in duct bottom; Make bottom other directions of suffered frictional ratio big, bottom abrasion is very fast, has shortened the working life of pipeline.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and the thickening of a kind of bottom is provided, thereby improves the special-shaped steel skeleton plastic clad pipe of internal layer in its working life.
For realizing above-mentioned purpose; The technological scheme of the utility model is adhering resin layer and compound respectively inner layer plastic tube and the outer layer plastic tube that is arranged at the inside and outside both sides of adhering resin layer that includes Steel Skeleton, Cladding Steel skeleton, thick on one side, the thin setting on one side of the wall thickness of described inner layer plastic tube.
The external diameter center of circle (O1) and the internal diameter center of circle (O2) that further setting is described inner layer plastic tube do not overlap, and it is eccentric to form the center of circle, thick on one side, one side thin structure of the wall thickness that constitutes above-mentioned inner layer plastic tube.
Further being provided with is that the center of circle, inside and outside footpath of said outer layer plastic tube, Steel Skeleton and adhering resin layer and the external diameter center of circle of inner layer plastic tube coincide.
The thick one side of described eccentric steel skeleton plastic clad pipe wall thickness when installing and using downwards as duct bottom.
Advantage of the utility model and good effect:
The utility model has the advantages that: when steel skeleton plastic clad pipe is gathered the conveyance conduit application as the sylvite salt pan; Through increasing composite pipe wall thickness on one side; But thereby the wear extent of increase duct bottom; Avoided very fast, caused the phenomenon of the bearing capacity decline of pipeline, prolonged the working life of pipeline exponentially because of the duct bottom wearing and tearing.
Though this model utility increases than the cost of plain carbon steel frame plastic composite pipe because of having increased wall thickness on one side to some extent, the pipeline longer service life through increasing less cost, has obtained long working life, and cost performance is higher.Improve the whole wall thickness of pipeline and realize the purpose that increases the service life, more pointed, pipeline configuration is more reasonable, has reduced the production user cost widely.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model structural representation;
Among the figure, 1 inner layer plastic tube, 2 Steel Skeleton enhancement layers, 3 binding resin layers, 4 outer layer plastic tubes.
Embodiment
As shown in Figure 1, the eccentric steel skeleton plastic clad pipe that the utility model provides comprises inner layer plastic tube 1, Steel Skeleton enhancement layer 2, binding resin layer 3 and outer layer plastic tube 4.Inner layer plastic tube 1 adopts the plastic extruder extruding and moulding, and the wall thickness of control all directions does not overlap the external diameter center of circle O1 of inner layer plastic tube 1 and internal diameter center of circle O2 in the extrusion process; Steel Skeleton enhancement layer 2 on inner layer plastic tube 1 outer wall twines; Adopt extruder to extrude binding resin again, form binding resin layer 3 Steel Skeleton enhancement layer 2 is coated, be combined with each other with inner layer plastic tube 1; Adopt the extruder extrusion plastic to be coated on binding resin layer 3 outer wall at last, form outer layer plastic tube 4.
The external diameter center of circle O1 of the center of circle, inside and outside footpath of Steel Skeleton enhancement layer 2, adhering resin layer 3 and outer layer plastic tube 4 and inner layer plastic tube 1 coincides; The center of circle O1 and the O2 in the whole inside and outside footpath of steel skeleton plastic clad pipe are not overlapped; Form eccentric; Make steel skeleton plastic clad pipe wall thickness E1 the thinnest, E2 is the thickest, and E1 and E2 are on the same diameter.
In eccentric steel skeleton plastic clad pipe is installed with E2 place downwards as duct bottom, but increase the wear extent of duct bottom, reach the purpose in working life of prolongation pipeline.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
