Abstract
The utility model provides a composite pipe for a filter press, which is characterized in that the composite pipe has a double-layer structure and comprises an internal PP lining pipe and a stainless steel pipe which is sleeved outside the PP lining pipe, the section of the PP lining pipe has the same shape with that of the stainless steel pipe, and the outer diameter of the PP lining pipe is not larger than the inner diameter of the stainless steel pipe. The composite pipe for the filter press can be arranged at an outlet of the filter press, the PP lining pipe is made of polypropylene plastic, thus having higher flexibility, and being good in wear resistance and corrosion resistance; and as the double-layer structure that the stainless steel pipe is taken as the outer layer and the lining pipe is taken as the inner layer is adopted, the composite pipe for the filter press has the advantages of being high in pressure resistance, is not easy to break and leak with drips and the like.
Description
Technical field
The utility model relates to the tubing field, is specifically related to a kind of composite pipe.
Background technique
The existing pressure filter outlet glass steel pipelines that use more; Because the problem that this position deforms or ruptures because of pressure is excessive easily; The wearing and tearing of pipeline are very severe, and there is the problem that produces distortion or fracture because of expand with heat and contract with cold effect and build-up of pressure are excessive in the conventional glass steel pipe in application; And sealability is bad, occurs the evaporating, emitting, dripping or leaking of liquid or gas phenomenon easily; Common stainless steel pipeline does not reach the effect of high temperature resistant acid and alkali corrosion again.
Summary of the invention
The purpose of the utility model is intended to solve the deficiency of existing technology, provide a kind of simple in structure, technology is easy, set is firm, wear resistant corrosion resistant, long-lived composite pipe, can improve the bearing capacity and the anti-corrosive properties of pipeline.
The technological scheme of the utility model is:
A kind of pressure filter is used composite pipe; It is characterized in that: said composite pipe is a double layer construction; Comprise the Stainless Steel Tube that inner PP bushing pipe is outside with being set in said PP bushing pipe; Said PP bushing pipe is identical with the sectional shape of said Stainless Steel Tube, and the external diameter of said PP bushing pipe is not more than the internal diameter of said Stainless Steel Tube.
Further,
Said PP bushing pipe and Stainless Steel Tube are the ring cross section, and the external diameter of PP bushing pipe is slightly less than the internal diameter of Stainless Steel Tube.
Stick with glue between said PP bushing pipe and the said Stainless Steel Tube connect fixing.
Said glue is AB glue.
The pressure filter of the utility model can be installed in the pressure filter outlet port with composite pipe; The material of PP bushing pipe is a polypropylene plastic; Have higher pliability, and wear-resisting, corrosion resistance and good, and because Stainless Steel Tube is the double layer construction of internal layer as outer and PP bushing pipe; It is strong to make that also the pressure filter composite pipe of the utility model has crushing resistance, is difficult for breaking, advantage such as water clock.

Embodiment
Below in conjunction with accompanying drawing further explain is done in the practical implementation of the utility model.
The pressure filter of the utility model shown in Fig. 1-2 is with composite pipe 1; Adopt composite design; Composite pipe is a double layer construction; Comprise the Stainless Steel Tube 2 that inner PP bushing pipe 3 is outside with being set in the PP bushing pipe, the PP bushing pipe is identical with the sectional shape of Stainless Steel Tube, and the external diameter of PP bushing pipe is not more than the internal diameter of Stainless Steel Tube.
Stainless Steel Tube serves as skeletal structure, and the PP bushing pipe of liner is processed by polypropylene plastic, has the wear resistant corrosion resistant function; PP bushing pipe hollow forms tube chamber 4; Not can with the material generation chemical reaction that flows in the pipeline, and can effectively metallic shell and material easy and material generation chemical reaction be separated, prevent that metal impurities are introduced in the tube chamber; Thereby prevent that metal impurities from sneaking in the material that is transferred; In acid-alkali-corrosive-resisting, solved pipeline because of excessive distortion that produces of expand with heat and contract with cold effect and pressure or breakage problem, have the advantage that cost is low, the life-span is long.
In this example, the internal surface of the Stainless Steel Tube of the utility model is fixedly connected through AB glue with the outer surface of PP bushing pipe.
The outer surface of the internal surface of the Stainless Steel Tube of the utility model and PP bushing pipe also can be uncoated flexible connection.
In this example, PP bushing pipe and Stainless Steel Tube are the ring cross section, and the external diameter of PP bushing pipe is slightly less than the internal diameter of Stainless Steel Tube, so Stainless Steel Tube is set in outside the PP bushing pipe, stick with glue between the two connect fixing, simple in structure, easy processing.The PP bushing pipe of the utility model and the sectional shape of Stainless Steel Tube can also be other shapes, as long as guarantee that both sectional shapes are consistent.
The pressure filter of the utility model is installed in the pressure filter outlet port with composite pipe, and when the material entering PP of band temperature, pressure bushing pipe, PP bushing pipe expanded by heating receives the protection of outer Stainless Steel Tube; During acidity material process composite pipe, the PP lining pipe of Stainless Steel Tube liner plays etch-proof effect to stop the corrosion of material to Stainless Steel Tube, so the composite pipe of the utility model is durable lasting, is difficult for breaking, and has good practical value.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technological scheme to any simple modification, equivalent variations and modification that above embodiment did.
