Abstract
The utility model discloses a vacuum infiltration-assisting device. The vacuum infiltration-assisting device comprises a vacuum pump, a ventilation pipeline, a three-way valve and an infiltration-assisting tank, wherein the vacuum pump is communicated with the infiltration-assisting tank through the ventilation pipeline and the three-way valve. According to the device, the vacuum pump is communicated with the infiltration-assisting tank through the ventilation pipeline and the three-way valve, the inside of the infiltration-assisting tank can be pumped to be vacuum, to-be-tested membranes are infiltrated under the cooperation of the vacuum state and the air entering the infiltration-assisting tank quickly, and the device has the advantages of high infiltration efficiency, good infiltration effect and capability of improving the test precision.
Description
Technical field
The utility model relates to bubble platen press pore analysis instrument device, particularly relates to a kind of to sample being infiltrated to the device of processing before bubble platen press pore analysis instrument test sample.
Background technology
The pore structure of porous membrane is important structural parameters, is directly connected to the permeability and separation performance of film.Gas foam platen press is a kind of important analytical approach that is mainly used in test aspect, membrane material aperture, and the method, according to capillary theory, is utilized capillary effect, adopts the corresponding relation of capillary pressure and bore dia to carry out instrument connection diameter.Gas foam platen press is typically to utilize gaseous tension that the liquid in fenestra is discharged, and directly obtains the pore diameter distribution of finished product or semi-manufacture film.Gas foam platen press can also detect maximum diameter of hole or the flaw size of film in addition.
In test process, be exactly first by tested film complete wetting, immersion agent to be entered in the hole of film completely.The infiltration degree of film directly affects the accuracy of experimental result.At present, the device of installing for the infiltration of film is not set on bubble platen press pore analysis instrument both domestic and external, impregnation process is sample to be infiltrated to be put into other containers such as double dish or beaker, adds immersion agent, places certain hour and realizes nature infiltration.
Under existing employing normal pressure, naturally infiltrate the film of test, infiltrating time used is longer, and has the inadequate problem that infiltrates.More abundant for what make to infiltrate, generally all need to spend the night the even longer time, it is low that this will make to infiltrate efficiency, weak effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of vacuum and helps profit device, can to the film of test, infiltrate fast, meet test request, thereby solve the existing film that naturally infiltrates the test of bubble platen press pore analysis instrument under employing normal pressure, infiltrating time used is longer, and has the inadequate problem that infiltrates.
For solving the problems of the technologies described above, the utility model provides a kind of vacuum to help profit device, comprising:
Vacuum pump, vent line, T-valve and help profit pond; Wherein,
Described vacuum pump through described vent line and described T-valve with described in help profit pond to be communicated with.
The beneficial effects of the utility model are: by vacuum pump is communicated with helping profit pond through vent line and T-valve, can make to help in profit pond and vacuumize, under vacuum state coordinates with the air entering fast, the film of test is infiltrated, there is the efficiency of infiltration high, effect of impregnation is good, improves the advantage of measuring accuracy.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain other accompanying drawings according to these accompanying drawings.
The bubble platen press pore analysis instrument vacuum that Fig. 1 provides for the utility model embodiment helps the structural representation of profit device.
Embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.
The utility model embodiment provides a kind of vacuum to help profit device, and as shown in Figure 1, this device comprises: vacuum pump, vent line, T-valve and help profit pond;
Wherein, vacuum pump 1 is communicated with helping profit pond 3 through vent line 2 and T-valve 4.
Above-mentioned vacuum help profit device in, two valves 41,42 of T-valve 4 on vent line 2, the 3rd valve 43 and air communication between two valves 41,42.
Above-mentioned vacuum helps in profit device, preferred, and T-valve 4 adopts solenoid valve; Also comprise: control device 5, be electrically connected to solenoid control end, control the keying of each valve of solenoid valve.
Below in conjunction with accompanying drawing and specific works engineering, to vacuum of the present utility model, help profit device to be described further.
The utility model embodiment provides a kind of vacuum to help profit device, can infiltrate fast the film of bubble platen press pore analysis instrument test, this vacuum helps profit device can be mounted on bubble platen press pore analysis instrument, comprise: help profit pond 3, vacuum pump 1, vent line 2 and T-valve 4, vacuum pump 1 is communicated with helping profit pond 3 through vent line 2 and T-valve 4, two valves of T-valve 4 on vent line 2, the 3rd valve 43 and air communication between two valves 41,42.Preferably, T-valve 4 adopts solenoid valve; Also comprise: control device 5, be electrically connected to solenoid control end, control the keying of each valve of solenoid valve, thereby convenient realization automatically controlled.
Utilize above-mentioned vacuum to help profit device, impregnation process is as follows:
Membrane sample is put into and helped profit pond 3, add appropriate immersion agent, first vacuum pump 1 is opened, now control the valve 41 and 42 of T-valve 4 and open, valve 43 is closed, vacuumize after end, control the valve 41 of T-valve 4 and close, valve 42 and 43 is opened, now because external environment and vacuum help the external and internal pressure of profit device poor, what make that outside air moment enters that vacuum helps profit device helps profit pond 3, and under the effect of pressure, immersion agent is pressed in the hole of film.Repeatedly this operation repeatedly, had both saved infiltrating time, made again film be infiltrated fully, and whole impregnation process is controlled and automatically completed by control device 5.
In sum, this vacuum helps profit device, has the efficiency of infiltration high, and effect of impregnation is good, improves the advantage of measuring accuracy.While being used on bubble platen press pore analysis instrument, its impregnation process and test process can complete independentlies, are independent of each other.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
