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 lining form the production technology with ultra-fine stay pipe.
Background technology
The liner of the film silk using in current MBR film group device is the microfiltration membranes silk of diameter 2.5mm left and right, the stay pipe pipe diameter that this film silk is used is 1.9mm, cause film filament diameter larger, cause the loading density of diaphragm lower, and this kind of film silk filter area is in use little, 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 by reducing the diameter of stay pipe, improve the loading density of group device, can effectively improve filter area and water yield under equal volume, and on the filtering accuracy of film silk and stability without impact.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of with lining form the production technology 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 equal volume.
Of the present invention with lining form the production technology with ultra-fine stay pipe, comprise the following 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 braider and is woven, braider temperature is arranged on 80 ℃-210 ℃;
3) open braider, yarn completes interior hole forming on plug, carries out profile and again shapes, then completed and shunk sizing by bottoming hole by magnetic hole, is stay pipe after winding device.
Of the present invention with lining form the production technology with ultra-fine stay pipe, described industrial filament is polyester or polypropylene artificial filament.
Of the present invention with lining form the production technology with ultra-fine stay pipe, described braider specification be 16 ingot-32 ingots without tatting loom.
Compared with prior art beneficial effect of the present invention is: of the present inventionly with lining form, by the production technology of ultra-fine stay pipe, can solve the lower problem of film silk loading density of existing MBR film group device, 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 stay pipe that diameter is little, can greatly increase the film silk water yield in film silk unit volume, applicable small-sized water purifier is used widely.
Accompanying drawing explanation
Fig. 1 be a kind of described in the embodiment of the present invention with lining form the structural representation with the knit unit of ultra-fine stay pipe;
Fig. 2 be a kind of described in the embodiment of the present invention with lining form the structural representation with the wrap-up of ultra-fine stay pipe;
Fig. 3 be a kind of described in the embodiment of the present invention with lining form the braiding texture maps by 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 illustrating the present invention, but are not used for limiting the scope of the invention.
As Figure 1-3, a kind of with lining form the production technology with ultra-fine stay pipe, comprise the following steps:
1) select the industrial filament of 0.9g/d-4g/d as raw material;
2) by industrial filament according to weight, number of plies requirement, sequentially by doubling winder, be wound on spool;
3) by the spindle winding 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 of 24 spindles is pulled out together, by the magnetic hole of eyelet strip 4, by bottoming hole, then on rolling-up mechanism, carrying out " O " type is again wound around, finally stay pipe exit is pressed to the fabric wheel below on winding wheel, plug 5 elevated height of eyelet strip below are exposed to the upper surface 1-3mm that yarn passes through magnetic hole to plug needle point 6, emit 7 to adjust to suitable height on the top on plug 5, make 24 count yarns in top, emit 6 tops to be merged together,
Open braider, the domain of two groups of each 12 spindles starts to relatively rotate, in rotation process, rolling-up mechanism (winding wheel 9 and 10) starts to carry out rolling simultaneously, make yarn or obtain a pulling force making progress, yarn is pulled out from spindle, through relatively rotating of different colours spindle, obtain interlaced weave effect, at plug needle point 6 places, start preliminary internal diameter sizing, top emit 7 with the effect in eyelet strip 4 magnetic holes under carry out secondary shape sizing, stay pipe 8 after having shaped starts to move upward under the effect of pulling force, pass through bottoming hole, industrial filament carries out after receiving temperatures involved that trace shrinks and carry out heat setting action.Stay pipe 8 external diameters after thermal finalization are 0.8mm-1.3mm, and then, after rolling-up mechanism, stay pipe is cooling, at fabric wheel 11 rear supporting tubes, just complete production process.
Of the present invention with lining form the production technology 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 lining form the production technology with ultra-fine stay pipe, described inkle loom specification be 16 ingot-32 ingots without tatting loom.
Of the present inventionly with lining form, by the production technology of ultra-fine stay pipe, can solve the lower problem of film silk loading density of existing MBR film group device, 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, the film silk that adopts the stay pipe that diameter is little, can increase the film silk water yield in film silk unit volume greatly, and applicable small-sized water purifier is used widely.
The above is only 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 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.
