Abstract
The utility model discloses a punching filter tube. The punching filter tube comprises a tube body made from polytetrafluoroethylene, wherein the cross section of the tube body is circular, a plurality of filter holes are formed in the surface of the tube body, filter membranes are arranged in the filter holes, and the openings of the filter holes are inclined upwards. The punching filter tube is simple in structure, convenient to use, high in wear resistance and good in filtering effect, and materials of the filter membranes are saved.
Description
Technical field
The utility model relates to a kind of pipe, particularly a kind of punching screen pipe.
Background technology
Screen pipe has another name called " filter pipe " " screen casing ".The most famous " Johnson's pipe " at last.But screen pipe has a variety of, filter pipe is considered to the heart of well casing usually, China's water supply industry adopts cast iron pipe or the steel pipe that twines the silk perforation usually, this class filter pipe is subject to the effect of chemistry, electrochemistry and bacterium and is corroded and stops up in underground water, reduce water inlet efficient and reduce the well life-span.Particularly when underground aqueous corrosion was strong, violent destruction can make a large amount of grit pour in the well, cause the silt well and burn out water pump, so that well is scrapped.For addressing this problem, work out stainless steel filter both at home and abroad, the fiberglass filter, asbestos or pipe of cement twine a filter, and paste and sharpen filter etc., but all because cost of raw material height, the processing technology complexity, capacity of outlet water is low, and factor such as physique structure heaviness is restricted its range of application, and can not get generally promoting.
The flexible pipe anti-wear performance of prior art is poor, and filter effect is also poor, and service life is short.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, and the anti-wear performance height, the punching screen pipe that good filtration effect, filter membrane material are more saved.
The utility model is achieved through the following technical solutions:
A kind of punching screen pipe comprises the body of being made by polytetrafluoroethylene (PTFE), and the cross section of described body is circular, and the surface of body is provided with some filter bores, is furnished with filter membrane in the filter bores, and the opening of filter bores is inclined upwardly.
As preferably, described filter bores is oval.
As preferably, described filter membrane is double-decker.
The beneficial effects of the utility model are: because the cross section of described body is for circular, the surface of body is provided with some filter bores, be furnished with filter membrane in the filter bores, the opening of filter bores is inclined upwardly, so by the effective impurity in the filter liquide of the filter membrane in the filter bores, the opening of filter bores is inclined upwardly, and the pressure in the direct impact filtration of liquid hole is big, and filter effect also can be better.Because described filter bores is oval, oval-shaped major axis is vertical layout, so good filtration effect.Because described filter membrane is double-decker, so filter membrane adopts double-decker, filter effect can be better.Body is wear-resisting, long service life, and the inner surface of body is not all arranged filter membrane, and only is to arrange filter membrane in the filter bores, so saved the material of filter membrane greatly, material is more saved.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model punching screen pipe.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figure 1, a kind of punching screen pipe, comprise the body of being made by polytetrafluoroethylene (PTFE) 1, the cross section of body 1 is circular, the surface of body 1 is provided with some filter bores 2, is furnished with filter membrane 3 in the filter bores 2, and the opening of filter bores 2 is inclined upwardly, filter bores 2 is oval, and filter membrane 3 is double-decker.
The utility model punching screen pipe, by the effective impurity in the filter liquide of the filter membrane 3 in the filter bores 2, the opening of filter bores 2 is inclined upwardly, the pressure in the direct impact filtration of liquid hole 2 is big, filter effect also can be better, and filter membrane 3 adopts double-decker, and filter effect can be better; Body 1 is wear-resisting, long service life, and the inner surface of body 1 is not all arranged filter membrane, and only is to arrange filter membrane 3 in the filter bores 2, so saved the material of filter membrane greatly, material is more saved.
The above only is the specific embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (3)
1. a punching screen pipe comprises the body of being made by polytetrafluoroethylene (PTFE), it is characterized in that: the cross section of described body is for circular, and the surface of body is provided with some filter bores, is furnished with filter membrane in the filter bores, and the opening of filter bores is inclined upwardly.
