Description

The rolling ro components of inner pressed
Technical field
The present invention relates to a kind of reverse-osmosis membrane elements.
Background technique
Reverse-osmosis membrane element is common component in water purifier.In order to save space and easy to install and use, traditional is anti- Infiltration membrane element is all using single film bag by the way of the water producing pipe spiral winding of center, to be ultimately formed to the close film bag of multilayer Layer is constituted cylindric, and central tube is as collector pipe, the collector pipe of the multilayer pure water collection of film bag to the heart in the component, in The outflow of heart pipe, waste water are flowed out by the outlet on external protection coating, that is, putamina, and pure water runner direction is inside spin form.It is this traditional Mode needs the assembly or disassembly of reverse-osmosis membrane element and putamina, at high cost, inconvenient for use.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide, one kind is at low cost, flow velocity is fast, produces The rolling ro components of big, the easy to use inner pressed of water.
The technical scheme adopted by the invention is that: the present invention includes putamina component, central tube, film bag, the film bag winding In the outer wall of the central tube, and multilaminate coiled structure is formed, the both ends of the central tube are connected to the putamina component respectively Original water inlet, wastewater outlet, the inner cavity center of the central tube is equipped with partition and is separated into the inner cavity of the central tube Lower two cavitys, the epicoele body sidewall of the central tube are equipped with several water outlets, cavity of resorption body sidewall equipped with several times The mouth of a river, the putamina component are equipped with pure water outlet and communicate with the inner cavity of the putamina component, and raw water passes through the original water inlet It is entered in the film bag into the upper cavity of the central tube, and from the water outlet, after osmosis filtration, pure water is from institute The inner cavity that film bag flows out to the putamina component is stated, and is flowed out from the pure water outlet, waste water is in the film bag from described time The lower chamber of the central tube is flowed back at the mouth of a river, finally flows out from the wastewater outlet.
The film bag it is open at one end, and in the original water inlet, the wastewater outlet be paperwrapped in.
The film bag includes centrally located raw water grid, the reverse osmosis membrane positioned at raw water grid two sides, adjacent The film bag between be equipped with pure water selvage guide.
The beneficial effects of the present invention are: the film bag is wound in since the present invention includes putamina component, central tube, film bag The outer wall of the central tube, and multilaminate coiled structure is formed, the both ends of the central tube are connected to the putamina component respectively Original water inlet, wastewater outlet, the inner cavity center of the central tube are equipped with partition and are separated into the inner cavity of the central tube up and down Two cavitys, the epicoele body sidewall of the central tube is equipped with several water outlets, cavity of resorption body sidewall is equipped with several return water Mouthful, the putamina component be equipped with pure water outlet communicated with the inner cavity of the putamina component, raw water pass through the original water inlet into Enter the upper cavity of the central tube, and entered in the film bag from the water outlet, after osmosis filtration, pure water is from described Film bag flows out to the inner cavity of the putamina component, and flows out from the pure water outlet, and waste water is in the film bag from the return water Mouth flows back to the lower chamber of the central tube, finally flows out from the wastewater outlet;The present invention overcomes the defect of the prior art and Deficiency has abandoned traditional thinking, overcomes the technology prejudice of this field, acts in a diametrically opposite way, and proposes a kind of unusual Technology path be reverse flowed to design reverse-osmosis membrane element using principle of reverse osmosis, the pure water outside the film bag is outside by center Side flowing, can be reduced the flow resistance for producing water, mitigate the pressure in film bag, improve flow velocity, effectively improve water yield, integration knot External protection coating of the structure not by existing fixation is limited, and inlet and outlet pipe is directly connected to, and save the cost, use scope is wide, just In installation, Yi Shixian;Therefore the present invention is at low cost, and flow velocity is fast, and water yield is big, and it is easy to use, it is a kind of rolling reverse osmosis of inner pressed Saturating element.
