The through hole of the center water producing pipe that Fig. 2 provides for the utility model embodiment is the structural representation of slotted eye.
Embodiment
Core of the present utility model is to provide a kind of center water producing pipe of reverse-osmosis membrane element, accelerates to produce confluxing of water, reduces reverse osmosis membrane back pressure.Another core of the present utility model is to provide a kind of reverse-osmosis membrane element with above-mentioned center water producing pipe, and has the water-purifying machine of this reverse-osmosis membrane element.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model discloses a kind of center water producing pipe of reverse-osmosis membrane element, it comprises the body 1 with through hole 3, and through hole 3 is the narrower bore being greater than the length of the circumference along body 1 along the length of the axis of body 1.Through hole 3 is set to narrower bore, increase the length of the axis along body 1 when the length of the circumference along body 1 is constant relative to circular port, thus reach the object increasing water inlet area, under the prerequisite that the water inlet working pressure of reverse-osmosis membrane element is constant, the collection rate of pure water after reverse osmosis membrane can be improved, thus improve the product water efficiency of reverse-osmosis membrane element.
In specific embodiment, body 1 has circumferentially been evenly arranged at least two exhausting holes 3.When arranging two exhausting holes 3, be separated by 180 ° between this two exhausting hole 3, when for n row (n >=3), the angle of being separated by between adjacent two exhausting holes 3 is 360/n degree.The application arranges many exhausting holes 3 on body 1, can increase the area of overall water inlet further.Through hole 3 is evenly arranged along the circumference of body 1 and can ensures the even of reverse osmosis membrane back pressure.
In preferred embodiment, the through hole number of every exhausting hole 3 is 5-10, can need the through hole number selecting every exhausting hole 3 in practice according to the length of center water producing pipe and diameter, and all in protection domain, as long as the backpressure requirements of the center of guarantee water producing pipe.
For the ease of increasing the drainage rates of center water producing pipe, in the application, the shutoff end 2 of the distance between through hole 3 adjacent in the through hole 3 often arranged by body 1 is increased gradually to water side 4.By above-mentioned setting, the number of the through hole 3 near shutoff end 2 can be made many, more pure water is entered in the water producing pipe of center, and the number of through hole 3 near water side 4 is few, differential back is herein larger accordingly, the flow rate of water side 4 can be made high, the water resistance avoiding water side 4 hinders the confluxing and discharging of water near shutoff end 2, and to sum up, above-mentioned setting can ensure stablizing of current in the water producing pipe of center, prevent disturbance, improve drainage rates.
In practice, in order to improve drainage rates, also can be increased in every exhausting hole 3 gradually by the length of the shutoff end 2 of body 1 to the through hole of water side 4, when width is constant, is in every exhausting hole 3 and is increased gradually by the long-width ratio of the shutoff end 2 of body 1 to the through hole 3 of water side 4, because the hole in the application is narrower bore, and it is larger along the length of the axis of body 1, therefore, the length in this direction is for long, and the length of the circumference of body 1 is wide.By above-mentioned setting, the length near the through hole 3 of shutoff end 2 is made to be less than the length of the through hole 3 near water side 4, namely the area of the through hole 3 of close shutoff end 2 is less than the area of the through hole 3 near water side 4, the flow velocity near shutoff end 2 is made to be less than the flow velocity of close water side 4, the water resistance avoiding water side 4 hinders the confluxing and discharging of water near shutoff end 2, and to sum up, above-mentioned setting can ensure stablizing of current in the water producing pipe of center, prevent disturbance, improve drainage rates.
On the basis of technique scheme, in the application, through hole 3 is set to slotted eye or rectangular opening, as long as through hole 3 is greater than the circumference along body 1 length shapes along the length of the axis of body 1 can be met.The core of the application is when ensureing that through hole 3 is constant along the length of body 1 circumference, can increase the area of through hole 3, therefore, can only increase the length of through hole 3 along body 1 axis.Concrete size for through hole 3 can be selected according to different needs.
In further embodiment, define the length of through hole 3 along the circumference of body 1, be specially 30% of the external diameter being not more than body, to ensure the intensity of the circumference of body 1, prevent through hole 3 be out of shape and affect the work-ing life of reverse-osmosis membrane element.
