Abstract
The invention relates to a production process of a superfine supporting pipe for a lined membrane, which comprises the following steps of: 1, using 0.9g/d to 4g/d of industrial filaments as raw materials; 2, winding the industrial filaments on a cop tube according to a certain length/weight requirement by a doubling machine and installing the industrial filaments on a braiding machine according to a certain sequence; 3, ensuring an installed spindle to pass through a magnetic hole and a heating hole of a threading plate to be connected to a winding wheel of the braiding machine and the position below a pressing wheel behind the winding wheel; and 4, starting the braiding machine to braid the round supporting pipe with the outer diameter of 0.8mm to 1.3mm. After the supporting pipe passes through the heating hole, the braiding is completed. According to the production process of the superfine supporting pipe for the lined membrane, which is disclosed by the invention, the problem of low membrane filling density of an existing MBR (Membrane Biological Reactor) membrane assembler can be solved; and by reducing the outer diameters of membrane yarns, particularly the diameter of the supporting pipe, the assembler water yield in unit volume can be greatly improved under the condition of a constant membrane flux in unit square meters and in a limited filling space.
Description
Technical field
The present invention relates to a kind of with the production technology of lining form with ultra-fine stay pipe.
Background technology
The liner of employed film silk is the microfiltration membranes silk about diameter 2.5mm in the present MBR film group device, the stay pipe pipe diameter that this film silk uses is 1.9mm, cause the film filament diameter larger, cause the loading density of diaphragm lower, and this kind film silk filter area in use is little, and water yield is also lower.Because the material cost of stay pipe is high, it is low that thick stay pipe is compared ramuscule stay tube effective rate of utilization; And improve the loading density of organizing device by the diameter that reduces stay pipe, can effectively improve filter area and water yield under the equal volume, and filtering accuracy and the stability nothing of film silk affected.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind ofly with the production technology of lining form with ultra-fine stay pipe, can reduce the diameter of stay pipe, and then the loading density of raising group device, can effectively improve filter area and water yield under the equal volume.
Of the present invention with the production technology of lining form with ultra-fine stay pipe, may further comprise the steps:
1) select the industrial filament of 0.9g/d-4g/d as raw material;
2) industrial filament is wound on the spool of doubling winder, then spindle is installed on the braider and weaves, the braider temperature is arranged on 80 ℃-210 ℃;
3) open braider, yarn is finished interior hole forming at plug, carries out profile by the magnetic hole and again finalizes the design, and finishes by bottoming hole and shrinks typing, is stay pipe through behind the winding device.
Of the present invention with the production technology of lining form with ultra-fine stay pipe, described industrial filament is polyester or polypropylene artificial filament.
Of the present invention with the production technology of lining form with ultra-fine stay pipe, described braider specification is that the nothing of 16 ingots-32 ingot tats loom.
Compared with prior art beneficial effect of the present invention is: the lower problem of film silk loading density that can solve existing MBR film group device with lining form with the production technology of ultra-fine stay pipe of the present invention, by reducing the external diameter of film silk, especially the diameter of stay pipe (braid of support membrane silk top layer membrane material), under the constant condition of unit square meter membrane flux, under limited charge space, adopt the film silk of the little stay pipe of diameter, can greatly increase the film silk water yield in the film silk unit volume, suitable small-sized water purifier uses widely.

Fig. 1 is that the embodiment of the invention is described a kind of with the structural representation of lining form with the knit unit of ultra-fine stay pipe;
Fig. 2 is that the embodiment of the invention is described a kind of with the structural representation of lining form with the wrap-up of ultra-fine stay pipe;
Fig. 3 is that the embodiment of the invention is described a kind of with the braiding texture maps of lining form with the production technology of ultra-fine stay pipe.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As Figure 1-3, a kind of with the production technology of lining form with ultra-fine stay pipe, may further comprise the steps:
1) select the industrial filament of 0.9g/d-4g/d as raw material;
2) with industrial filament according to weight, number of plies requirement, sequentially be wound on the spool by doubling winder;
3) with the spindle that winds according to braider spindle (1,2) color is installed respectively, during installation, the spindle switched in opposite of installing on the spindle of two kinds of colors (12 spindles of every kind of color), then the upper yarn 3 with 24 spindles pulls out together, magnetic hole by eyelet strip 4, then carrying out " O " type at rolling-up mechanism by bottoming hole again twines, at last the stay pipe exit is pressed the fabric wheel below on the winding wheel, plug 5 elevated height of eyelet strip below are exposed the upper surface 1-3mm that yarn passes through the magnetic hole to plug needle point 6, emit 7 to adjust to suitable height on the top on the plug 5, make 24 count yarns emit 6 tops to be merged together in the top;
Open braider, the domain of two groups of each 12 spindles begins to relatively rotate, in rotation process, rolling-up mechanism (winding wheel 9 and 10) begins to carry out rolling simultaneously, make yarn or get a pulling force that makes progress, yarn is pulled out from spindle, through relatively rotating of different colours spindle, obtain interlaced weave effect, begin preliminary internal diameter typing at plug needle point 6 places, the top emit 7 with the effect in eyelet strip 4 magnetic holes under carry out the secondary shape typing, the stay pipe 8 after typing is finished begins to move upward under the effect of pulling force, by bottoming hole, industrial filament carries out the trace contraction and carries out heat setting action after receiving temperatures involved.Be 0.8mm-1.3mm through stay pipe 8 external diameters after the thermal finalization, then pass through rolling-up mechanism after, the stay pipe cooling is just finished production process at fabric wheel 11 rear supporting tubes.
Of the present invention with the production technology of lining form with ultra-fine stay pipe, described industrial filament is for can be PFY, volume propylene long filament etc. artificial filament.
Of the present invention with the production technology of lining form with ultra-fine stay pipe, described inkle loom specification is that the nothing of 16 ingots-32 ingot tats loom.
The lower problem of film silk loading density that can solve existing MBR film group device with lining form with the production technology of ultra-fine stay pipe of the present invention, by reducing the external diameter of film silk, especially the diameter of stay pipe (braid of support membrane silk top layer membrane material), under the constant condition of unit square meter membrane flux, under limited charge space, adopt the film silk of the little stay pipe of diameter, can greatly increase the film silk water yield in the film silk unit volume, suitable small-sized water purifier uses widely.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
