Description
Technical field
The utility model relates to membrane component technical field, especially a kind of wound membrane element.
Background technology
Wound membrane element comprises counter-infiltration, ultrafiltration, nanofiltration etc., and its modular construction is made up of diaphragm, water inlet filter, fresh water collecting net, glue, central tube, end cap, y-type seal ring.Particularly diaphragm, water inlet net, fresh water collecting Netcom are crossed that glue is bonding to be wrapped on central tube, then adopt end cap to encapsulate on central tube two ends, and after adopting sealing ring encapsulation process, i.e. obtainable membrane component.And in prior art, the connected mode for end cap and central tube mainly contains smooth connection, nested encryptions, hot-melt adhesive paste etc.
Wherein, in smoothing junction fairly simple, the central tube of this connection and end cap contact position smoother, mainly fix by playing glue, but glue can seal around membrane component central tube, hindering passing through of former water, thus affect the performance of membrane component; Nested encryptions, mainly processes draw-in groove on central tube, end cap contact surface, and this connected mode is relatively more firm, but end cap all assists to connect with hammer up and down, thus can destroy end cap, causes dismounting inconvenient, adds maintenance cost; Hot-melt adhesive paste, is mainly merged central tube and end cap by high temperature, and technical requirement when this is connected to operation is higher, connection device more complicated, and cost compare is expensive, and end cap can not take off, and is unfavorable for the maintenance to membrane component.
Utility model content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of wound membrane element, this membrane component adopts the state of the mutual fastening of internal and external threads to be connected between central tube with end cap, and then can detachable maintaining be convenient to, also can be comparatively firm central tube and end cap be linked together, and then ensure that the quality of wound membrane element, reduce membrane component cost of manufacture and membrane component maintenance cost.
Specifically, wound membrane element, comprise film body, be wrapped in the central tube at Mo Shen center and be arranged on film body two ends end cap composition, end cap is wherein connected with central tube by screw thread.Screw thread is arranged on the outer surface of central tube, forms external screw thread, arranges internal thread in the inside of ending cover hole, also screw thread can be set at the inner surface of central tube, form internal thread, end cap arranges an extension tube, and the outer surface of extension tube is arranged screw thread, form external screw thread.
The film body of above-mentioned wound membrane element is combined by arbitrary two kinds or three kinds in reverse osmosis membrane, milipore filter, NF membrane.
The film body of the above-mentioned wound membrane element of concrete composition is by 2-8 layer reverse osmosis membrane and 1-3 layer milipore filter is cross layered forms, and from central tube outwards number, ground floor is milipore filter.
The film body forming above-mentioned wound membrane element can also be by 3-5 layer reverse osmosis membrane and layer 2-4 NF membrane is cross layered forms, and from central tube outwards number, ground floor is milipore filter.
The film body forming above-mentioned wound membrane element is preferably by 2-7 layer reverse osmosis membrane and 1-3 layer milipore filter and layer 2-4 NF membrane is cross layered forms, and from central tube outwards number, ground floor is milipore filter, and the second layer is reverse osmosis membrane, and third layer is NF membrane.
Compared with prior art, technique scheme can be the central tube of wound membrane element and the connection of end cap and dismantle difficulty and reduce, and by central tube external screw thread and end cap internal thread mate and central tube internal thread mates with end cap is externally threaded, and then ensure that the stable connection of end cap and central tube, improve the performance of wound membrane element, avoid the appearance of the technical problem in conventional art, former water resistance being hindered to the poor-performing of the wound membrane element caused, improve the water treatmenting performance of wound membrane element, make wound membrane element be easy to dismounting and assembling simultaneously, reduce the cost of manufacture of wound membrane element, and diaphragm layout is carried out to the film body of wound membrane element, and then improve the performance of wound membrane element.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, further restriction is done to the technical solution of the utility model, but claimed scope is not only confined to done description.
Embodiment
As shown in Figure 1, wound membrane element comprises film body 1, the end cap 2 that is wrapped in the central tube 3 at film body 1 center and is arranged on film body 1 two ends forms,
As shown in Figure 2, Figure 3, Figure 4, end cap 2 is connected with central tube 3 by screw thread 4.
As shown in Figures 2 and 3, screw thread 4 is external screw thread on central tube 3; It end cap 2 is internal thread.
Except above-mentioned screw thread cloth is not in the know, described screw thread 4 can also be internal thread on central tube 3; It end cap 2 is external screw thread.
On the basis of technique scheme change, the invention has also carried out diaphragm distributing adjustment to film body, is specially: film body 1 is combined by arbitrary two kinds or three kinds in reverse osmosis membrane, milipore filter, NF membrane.
Except above-mentioned diaphragm cloth is not in the know, particularly by film body 1 by 2-8 layer reverse osmosis membrane with 1-3 layer milipore filter is cross layered forms, from central tube 3 outwards number, ground floor is milipore filter.
Can also be that from central tube 3 outwards number, ground floor is milipore filter by film body 1 by 3-5 layer reverse osmosis membrane with layer 2-4 NF membrane is cross layered forms.
Preferably that from central tube 3 outwards number, ground floor is milipore filter, and the second layer is reverse osmosis membrane, and third layer is NF membrane by, film body 1 by 2-7 layer reverse osmosis membrane and 1-3 layer milipore filter and layer 2-4 NF membrane is cross layered forms.
