This testing component comprises front and back splint, guide arm, screw rod, the sealed pad. Sealed pad inlays in fore deck and the movable clamp plate's that lives recess, the membrane pipe fix the front plate with live between the movable clamp plate, back splint are equipped with the internal thread that matees with the screw rod, the crush seal of managing the membrane can be realized to the rotation screw rod. This subassembly convenient to use, it is sealed effectual, can realize the test to different pipe diameter samples through the diameter of adjustment recess, have better suitability.
Description
Technical field
This utility model belongs to filtration art, relates to a kind of tubular membrane test suite.
Technical background
Tubular membrane is a kind of form of film, it is adaptable to the isolation technics such as ultrafiltration, microfiltration, nanofiltration and reverse osmosis.Tubular membrane component has preferable mobility, and the pretreatment required precision to feed liquid is low, and membrane tube can dismount, it is easy to clean.Tubular membrane has higher mechanical strength, and its operation pressure ratio hollow-fibre membrane is high, and transparent liquid flux is higher.
At present, tubular membrane mainly has ceramic pipe type film, metal pipe type film and composite tubular type film.
The pore size of porous material and pore-size distribution directly affect performance and the application of porous material, therefore need to accurately measure aperture and the distribution thereof of membrane material.Measure aperture main method and have bubble method, liquid liquid exclusive method, suspension Filtration, gas osmosis etc..Assembly common on market uses many membrane tube to be assembled in putamina mostly, and it can obtain bigger filter area.Patent CN204485662U provides a kind of tubular membrane component of certainly connecting, and end cap is provided with guiding gutter, and it is interior and matched that tubular membrane port is located at guiding gutter, and then constitutes cascaded structure.Patent CN203079729U relates to a kind of sewage disposal cross flow tube type membrane module, some tubular membrane are parallel to each other and are located in barrel shell, film two ends are sealingly fastened in barrel shell two ends by end socket, produce cross-flow velocity, effectively stop the deposition of pollutant during use in membrane tube.
Laboratory characterizes the simplicity in view of operation, versatility to membrane material, need to design a kind of novel assembly reply unlike material, the tubular membrane of specification, and this assembly has preferable sealing effectiveness and can meet aperture and flux test simultaneously.
Summary of the invention
Technical problem to be solved in the utility model there is provided a kind of tubular membrane test suite being applied to pore analysis and water flux test, its design is simple and practical, with low cost, sealing preferable, and unlike material, diameter, the membrane sample of length are had good versatility.
This utility model adopts the following technical scheme that
Tubular membrane test suite, including front plate (2), sealing gasket (3), guide rod (4), ambulatory splint (5), rear plate (7) and screw rod (8).It is characterized in that: described sealing gasket is embedded in the groove of described front plate and described ambulatory splint, described membrane tube is fixed between front plate and ambulatory splint, described rear plate is provided with the female thread mated with described screw rod, and the screw rod described in rotation can realize the crush seal to described membrane tube.
When testing gas flux or with gas bubble platen press gaging hole footpath, the stop valve at outlet (6) place is closed and can complete dependence test.When testing the pure water flux of tubular membrane or with liquid liquid exclusive method gaging hole footpath, the air in assembly must be drained before testing, assembly is vertically placed, keep outlet (6) upper, entrance under (1), liquid enters assembly from inlet, owing to action of gravity liquid is gradually filled with assembly and membrane tube internal cavities, in time exporting (6) and have liquid to overflow, stop feed liquor and stop valve is closed, can test.
Described sealing ring external diameter is 1-8cm, and internal diameter is 2-5mm, and its outside dimension mates with the groove diameter arranged on described front plate and described ambulatory splint；Described membrane sample material is macromolecule, pottery, metal or composite；The a length of 5-100mm of described membrane tube, external diameter≤80mm；Described front plate is provided with import female thread, is used for connecting pneumatic fast joint；Described ambulatory splint is provided with outlet (6), connects stop valve.
Beneficial effect: tubular membrane component simple in construction of the present utility model, easy to operate, it is possible to be applicable to the multiple test such as pore analysis, flux, and good sealing effect；By adjusting sealing gasket groove diameter and guide rod length, the application of the tubular membrane of all kinds of material, dimensions can be met.
