Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and 2, interior pressure-pipe type film film tube performance testing device, is made up of following several parts:
Comprise support 1, top connection assembly 2 and upper and lower the aligning of lower contact assembly 3, two adapter assemblies are installed on support.Two adapter assemblies can be fixed on support by clamp respectively.Described top connection assembly is by upper cover 21 and be arranged on the upper plug head 22 being threaded connection with it in upper cover and form.Described lower contact assembly, by trapping 31 and be arranged on the lower end cap 32 being threaded connection with it in trapping and form, is provided with feeder 311 in the upper end of trapping, and is equipped with fluid through-hole at the center of upper plug head and lower end cap.Upper plug head and lower end cap be clogging film pipe 1 to be tested respectively, two-port.Concrete, at the upper locating hole that is provided with internal thread hole and matches with film pipe external diameter to be tested that puts, upper plug head is T connector structure, it is made up of large diameter portion and path part, large diameter portion is provided with the external screw thread matching with the internal thread hole of upper cover, and path part is consistent with the internal diameter of film pipe to be tested.When film pipe to be tested being inserted in the locating hole of upper cover, while being rotated down upper plug head, the path part of upper plug head is inserted in one end port of film pipe to be tested gradually, in the time that this end end face of film pipe to be tested and the circular bead surface of upper plug head compress, has completed this end fixing of film pipe.Trap identical with the fit structure of upper cover and upper plug head with the fit structure of lower end cap, trapping with the distinctive points of upper cover is: under put and be also provided with above-mentioned feeder.At this, to trapping and the structure of lower contact repeats no more.
Comprise material liquid tank 4, on material liquid tank, be provided with liquid outlet and liquid return hole, between the liquid outlet of material liquid tank and lower end cap, be communicated with liquor charging pipeline 5, on liquor charging pipeline, along the flow direction of feed liquid, supply-water pump 6, inlet valve 7 and Pressure gauge 8 are installed in turn, between the liquid return hole of material liquid tank and upper plug head, be communicated with back liquid pipeline 9, outlet valve 10 is installed on back liquid pipeline.
In said structure, on the sidewall of trapping, be further provided with the fluid hole 312 being communicated with feeder.The setting of fluid hole, has facilitated the liquid that sees through flowing in feeder has been taken out.
In this, the course of work of pressure-pipe type film film tube performance testing device is:
First film pipe to be tested is arranged between upper and lower plug, test feed liquid is left in material liquid tank, then open intake pump, regulate inlet valve and outlet valve, in adjustment process, read force value by Pressure gauge, test pressure scope is generally 0-1.5Mpa, when practical operation, be preferably 0.05-0.8Mpa, under the effect of pressure, test feed liquid enters in film pipe by liquor charging pipeline and lower end cap, in film pipe, upwards in mobile process, separate, form concentrate and see through liquid, concentrate is discharged from upper plug head, then be back in material liquid tank by reflux line, see through liquid flows in the feeder of trapping under the tube wall of film pipe, then by under the fluid hole that puts flow out, see through liquid through Collection and analysis, can calculate flux and the rejection of membrane pipe.
Above-mentioned test feed liquid can be pure water or the protein of known molecular amount or the aqueous solution of polymer, is used for test membrane pipe pure water flux and the rejection to different material.
Adopt this testing arrangement to carry out test membrane pipe, film pipe is fixed between upper and lower plug, and film pipe can freely be dismantled, change.At present, the diameter that often adopts film pipe is 3-25mm, for being suitable for the test of different tube diameters film pipe, can be equipped with top connection assembly and the lower contact assembly of many group different sizes, like this according to different film pipes, changes top connection assembly and the lower contact assembly of corresponding specification.
In this, pressure-pipe type film film tube performance testing device is applicable to interior pressure-pipe type film pipe flux and rejection performance test, be applicable to the performance test of tube type filter membrance, milipore filter, NF membrane, reverse osmosis membrane, easy to operate, quick, shorten the film tube performance testing cycle, can realize the quality control of film pipe production process, ensure the yield rate of membrane module and product, reduce defect rate, enhance productivity.
