Abstract
The invention discloses a porous central tube of a roll type membrane element; the porous central tube comprises a central tube body, and two connectors which are respectively separably connected with two ends of the central tube body, one end of each connector is open, the other end of each connector is closed, and the side wall of one of the connector is provided with a vacuum pumping hole communicated with an internal hole of the connector. When the porous central tube is used for winding the membrane element, a vacuum pumping machine is used for pumping vacuum between a feed flow channel network and a membrane bag by the vacuum pumping hole, and the gap between the feed flow channel network and the membrane bag can be reduced, winding compaction can be ensured, and the effect of membrane separation can be improved.
Description
Technical field
The present invention relates to a kind of antipriming pipe, be specifically related to a kind of porous central tube of rolled film element.
Background technology
In recent years, membrane separation technique as one separate efficiently, concentrate, purification and purification means, obtained development very rapidly.
It is component is had to the selective film that sees through function as separating medium that film separates, by apply (or existence) one or more motive forces in film both sides, make the membrane component in raw material optionally preferentially see through film, separate thereby reach mixture, and realize the separation process of the objects such as the extraction of product, concentrated, purifying.Press the shape of membrane component and the structure of assembly and divide, membrane component can be divided into flat sheet membrane, tubular membrane, rolled film and the large class of hollow-fibre membrane four.Rolled film element is because it is simple in structure, cheap, loading density is high, material exchange is effective, treating capacity is widely used greatly.
Rolled film element is generally made up of porous central tube, the parts such as film unit and outer protection structure that are wound on this central tube.Wherein, film unit comprises charging runner net and film bag, and film bag is to utilize adhesive will see through liquid runner net and the bonding integral structure forming of diffusion barrier sealing, for preventing charging runner net side feed liquid and mixing through runner net side liquid; Charging runner net is by supply side feed liquid guiding separation membrane surface, by diffusion barrier separating feed runner net side feed liquid; See through liquid runner net and will see through the guiding fluid central tube of diffusion barrier; Outer protection structure is generally technical grade membrane component glass fibre reinforced plastics casing or the outer catch net of sanitation-grade membrane component plastics, for wrapping up above-mentioned coiling body, can be single or multiple lift structure, for the mechanical strength of strengthening membrane element, and diaphragm element.
In prior art, there are following two effects in the porous central tube of rolled film element: (1) is convenient to the coiling of membrane component; (2) be through after liquid runner net guiding porous central tube through the liquid of diffusion barrier, flow out from porous central tube.And in the time that membrane component is wound on porous central tube, easily because of the coiling tightening force not consolidation that causes reeling not, thereby between charging runner net and film bag, there is larger gap, affect the effect of film separation.
Summary of the invention
The object of the invention is to provide a kind of porous central tube of rolled film element, by the improvement of structure, and when film unit is wound on porous central tube, coiling consolidation, the gap between charging runner net and film bag is little, and membrane separating effect is good.
For achieving the above object, the technical solution used in the present invention is: a kind of porous central tube of rolled film element, comprise central tube body, also comprise respectively detachable two joints that are connected in two ends with this central tube body, one end of described joint is uncovered, other end sealing, wherein described in one, on the sidewall of joint, offers the hole that vacuumizes being communicated with joint endoporus.
By said structure, in the time of coiling film unit, utilize evacuator that the vacuum between charging runner net and film bag is extracted, reduce the gap between charging runner net and film bag, ensure coiling consolidation, improve membrane separating effect.
In technique scheme, described in vacuumize hole and be connected with evacuator by a union elbow.
In technique scheme, the centre bore of the opening end of described joint and described central tube body is pegged graft, and on joint, is arranged with O RunddichtringO.
In technique scheme, described central tube body is provided with the circular hole that 4 row axially arrange along it, and the described circular hole of 4 row is evenly arranged along the circumferencial direction of porous central tube.
In technique scheme, the blind end end of described joint is provided with centre hole, the clamping position while being convenient to the outer catch net of rolled film element winding.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is at the two ends of porous central tube jointing respectively, and wherein on the sidewall of a joint, offer the hole that vacuumizes being communicated with joint endoporus, in the time of coiling film unit, utilize evacuator that the vacuum between charging runner net and film bag is extracted, reduce the gap between charging runner net and film bag, ensure coiling consolidation, improve membrane separating effect.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention one;
Wherein: 1, central tube body; 10, circular hole; 2, joint; 20, vacuumize hole; 3, joint; 4, O RunddichtringO; 5, union elbow.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment mono-: shown in Fig. 1, a kind of porous central tube of rolled film element, comprises central tube body 1,, other end sealing uncovered with one end of joint described in the detachable joint being connected 2 in two ends of this central tube body 1 and joint 3, two respectively.
Wherein, on the sidewall of described joint 2, offer be communicated with joint endoporus vacuumize hole 20.
The described hole 20 that vacuumizes is connected with evacuator by a union elbow 5.
The opening end of described joint 2 and joint 3 and the centre bore of described central tube body 1 are pegged graft, and on joint, are arranged with O RunddichtringO 4.
The blind end end of described joint 2 and joint 3 is provided with centre hole.
Described central tube body 1 is provided with the circular hole 10 that 4 row axially arrange along it, and the described circular hole 10 of 4 row is evenly arranged along the circumferencial direction of porous central tube.
The present invention is at the two ends of porous central tube jointing respectively, and wherein on the sidewall of a joint, offer the hole that vacuumizes being communicated with joint endoporus, in the time of coiling film unit, utilize evacuator that the vacuum between charging runner net and film bag is extracted, reduce the gap between charging runner net and film bag, ensure coiling consolidation, improve membrane separating effect.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
