Abstract
The invention discloses a tester for a reverse bubble point of a single filter core. The tester is provided with a sealing cover, wherein the sealing core is coincided with a filter core filtrate outlet and is used for packaging the filter core filtrate outlet; and an air pipe connecting opening is formed in the sealing cover. The invention also discloses a method for testing the reverse bubble point of the single filter core. The method sequentially comprises the following steps of: A, fully soaking and humidifying a membrane filter core by using sterile water; B, connecting the air pipe connecting opening of the tester with a compressed air source through a pipeline; C, connecting the sealing cover of the tester to the filtrate outlet in the membrane filter core in a sealing way, immersing the whole filter core in the sterile water, and introducing compressed air into the filter core through the compressed air source; and D, observing a testing result, if bubbles are continuously and regularly generated at a certain fixed position of the filter core, determining that the filter core is an integral unqualified filter core, and otherwise, determining the filter core is an integral qualified filter core. By the tester and the test method, the reverse osmosis integrality of the membrane filter core can be tested.
Description
Technical field
The invention belongs to the integrity test technical field of beer or Other Drinks membrane filtration system, be specifically related to a kind of list and prop up reverse bubble point tester of membrane filtration filter core and method of testing thereof.
Background technology
The integrality of beer or Other Drinks membrane filtration system is the important indicator that guarantees the membrane filtration effect, is directly connected to the accords with production standard of whether filtrating, and finally is related to the quality of finished product.
At present the integrity test method of membrane filtration system there are system complete property testing, single integrity test and the test of system reverse bubble point.The system complete property testing can only be as the detection method of a whole set of membrane filtration filter core, can not find out that wherein which filter core is defective; Single integrity test needs the process of voltage stabilizing and test, and is consuming time longer; The test of system reverse bubble point penetrates less position to filter core, is not easy to react and observe.Therefore, still there be not a kind of instrument and the method that can test single membrane filtration filter core integrality fast at present.
Summary of the invention
First purpose of the present invention is the weak point to prior art, provides a kind of and can test single membrane filtration filter core integrality fast whether qualified list props up the reverse bubble point tester of membrane filtration filter core.
Whether qualified second purpose of the present invention is to provide a kind of can test single membrane filtration filter core integrality method of testing fast.
For reaching first purpose, the present invention adopts following technical scheme:
Single the reverse bubble point tester of filter core has one and coincide with the filter core filtrate outlet and in order to seal the gland bonnet of filter core filtrate outlet, sealing covers and is provided with air pipe interface.
Further, the present invention also has a compressed air source, is connected with air pipe interface through pipeline.
For reaching second purpose, the present invention adopts following technical scheme:
Single the reverse bubble point method of testing of filter core, form by following steps successively:
A, fully soak moistening membrane filtration filter core with sterilized water;
B, the general air pipe interface of tester according to claim 1 are connected with a compressed air source through pipeline;
C, the gland bonnet of tester is sealably coupled on the filtrate outlet of membrane filtration filter core, and whole filter core is immersed in the sterilized water, feed pressurized air through compressed air source toward filter core then;
D, observation test result:, judge that then this filter core is the underproof filter core of integrality if a certain fixed position of filter core has the rule bubbling continuously; Otherwise, judge that then this filter core is the qualified filter core of integrality.
As preferably, in the A step, the temperature of sterilized water is 20 ℃～30 ℃.
As preferably, in the A step, the moistening time of the immersion of filter core is no less than 120 minutes.
As preferably, in the C step, compressed-air actuated pressure is 0.3～0.5bar.
Through the present invention, can carry out integrity test to the inverse osmosis of membrane filtration filter core, remedy and improve the deficiency of forward integrity test thus, guaranteed the tightness of integrity test; And easy and simple to handle saving time can be judged the concrete damaged position of filter core in quicklook ground.
