Abstract

The utility model relates to a multiple hole infiltration tube, the multiple holes arranged in the tube wall of which are composed of capillary tubes; the tube channels of the capillary tubes are tortuous, and the change of the hole diameter is large; the multiple holes arranged in the tube wall of the utility model is communicated with the outer wall to form grain-shaped rough outer wall surface. The utility model has the advantages of more than 80 percent of water saving, and no capillary holes blocking phenomenon after many trials, and furthermore, the water infiltration rate and pressure resistance strength are all higher than the water infiltration rate and pressure resistance strength of the multiple hole infiltration tube made in foreign countries.

Description

Multiporous infiltration tube

The utility model belongs to a kind of crop irrigation Multiporous infiltration tube, particularly in a kind of pipe that oozes of the porous tube wall that is made of capillary.

Ooze pipe and be after sprinkling irrigation, drip irrigation on irrigation technique another novel and effective water-saving irrigation technique is higher than the irrigation of any alternate manner to effective utilization of water resource.And technical performance is reliable, and easy to use being easy to grasped, and is convenient to application.At present, adopt rubber to make the capillary Multiporous infiltration tube and start from the U.S., but at its prescription, all also there are some problems in the capillary structure aspect of manufacturing machine and tube wall, average capillary radius as existing capillary Multiporous infiltration tube is too small, has influence on infiltrating irrigation efficient and energy resource consumption.

The purpose of this utility model is at problems of the prior art, improves through research repeatedly, proposes a kind of capillary aperture of making at new prescription slightly, seepage rate and all high Multiporous infiltration tube of compressive resistance.

The technical scheme of Multiporous infiltration tube of the present utility model is: the porous in this tube wall is to be made of capillary, pipeline complications capillaceous, and sensible outer wall in the tube wall forms the granular rough surface of tube wall; And varying aperture capillaceous is big, and its mean radius is 0.015-0.035mm.Average capillary radius in this tube wall is roughly 0.03mm.Described component and weight (%) thereof of oozing pipe is respectively: vulcanized rubber 55-65, vinyl 15-25, ABS (adhesive) 15-20, potter's clay 1-5.

The pipe difference of oozing of Multiporous infiltration tube of the present utility model and prior art is: adjusting the potter's clay that adds 1-5% outside its component ratio again at the raw material components interarea, and the draw ratio of Rubber Extruder was improved to 20: 1 by original 16: 1, thereby make the Multiporous infiltration tube that the big seepage rate in capillary aperture and compressive resistance all are higher than prior art.

For further specifying the concrete structure of Multiporous infiltration tube of the present utility model, can be referring to accompanying drawing:

Fig. 1 is the outline drawing of this Multiporous infiltration tube;

Fig. 2 is the tube wall capillary structural map that the tube wall section electron-microscope scanning of Multiporous infiltration tube shows;

In Fig. 1-2: 1 for oozing pipe, and 2 is tube wall, and 3 is capillary.

The major advantage of Multiporous infiltration tube of the present utility model is:

1, can economize on water more than 80%, and can reduce air themperature, improve face of land temperature Degree reduces the generation of disease and pest;

2, on probation through for many years, capillary finds that never capilar bore stops up the teacher in the wall Resemble;

3, by 3/8 inch pipe after measured, its seepage rate is 4 l/hs. rice, and The seepage rate of the product of the U.S. only is 1.6 l/hs. rice.

4, by 3/8 inch pipe after measured, its compressive resistance is 10kg/cm ², and U.S.'s product is 8kg/cm ²

As seen, the seepage rate of Multiporous infiltration tube of the present utility model and compressive resistance all are better than prior art.

Embodiment:

The weight percentages of components of this product is: vulcanized rubber 60%, and vinyl 20%, ABS17%, potter's clay 3%, the mean radius capillaceous of the Multiporous infiltration tube of producing is 0.03 ± 0.02mm.And the mean radius capillaceous of the Multiporous infiltration tube of the U.S. is 0.01 ± 0.001mm, and the capillary radius of this product is greater than the product of the U.S..Thereby improved seepage rate, reduced the energy consumption of knowing clearly.

Claims

1, a kind of Multiporous infiltration tube is characterized in that the porous in this tube wall is to be made of capillary, pipeline complications capillaceous, and sensible outer wall in the tube wall forms the granular rough surface of tube wall; And mean radius capillaceous is 0.015-0.035mm.

2, Multiporous infiltration tube as claimed in claim 1 is characterized in that the average capillary radius in the described tube wall is roughly 0.03mm.
