Abstract
The utility model discloses an online SDI (silt density index) measuring membrane scanning display storage system which comprises an automatically rolling roll-paper type online SDI measuring membrane device, wherein a device for capturing an image of a used membrane and an image memory are arranged above the rolled part of the measured membrane of the roll-paper type online SDI measuring membrane device. The image memory is an image memory with a time stamp. The system disclosed by the utility model has the beneficial effects that the image of the roll-paper membrane after the measurement is captured by the device for capturing an image before the membrane is rolled up, a scanned file is stored in a storage card or other storage media, and the file can be directly checked on a display screen of an instrument, or can be checked through on a computer after the storage card is taken down and connected with the computer.
Description
Technical field
The utility model relates to a kind of online SDI (pollution index) analysis meter, can realize that the 0.45um diaphragm is scanned into picture and numbering storage, in order to inquiring about and analyze use from now on.
Background technology
In the reverse osmosis water processing procedure, the SDI value is one of important symbol of measuring the counter-infiltration system water inlet; Be the main the means whether water outlet of check pretreatment system reaches the feed water by reverse osmosis requirement.Its size is most important to counter-infiltration system operation life.The SDI value is to measure through the 47mm diameter, and the decay of the flow velocity of 0.45um aperture film obtains.Why selecting the film in 0.45um aperture, is because under this aperture, and colloidal material is than grit material (like sand, incrustation scale etc.) easy blocking film more.The decay of flow velocity is converted into the numerical value between 1 to 100, i.e. the SDI value.The SDI value is low more, and water is more little to the pollution obstruction trend of film.
SDI (pollution index) analysis meter assay method: put into the filter membrane anchor clamps to the filter membrane of 0.45 μ m, open valve, and adjust pressure to 30psi and maintenance, collect water sample and also pick up counting, the required time of 500mL water sample collected in record is T0 (second).Water sample flowed after 15 minutes, collected 500mL water sample and record collection water sample institute's time spent with container once more, and note is made T15 (second).According to computes SDI value: SDI=(1-T0/T15) X100/15.
The precision that online SDI analysis meter is measured the water yield directly influences SDI result of calculation.Behind the manual measurement, the diaphragm that SDI (pollution index) analysis meter detects all was dropped in the past.
Summary of the invention
The utility model purpose is; Propose a kind of online pollution index measuring diaphragm scanning and show storage system; All adopt on the basis of coil paper formula diaphragm at existing online SDI; Also there be not contaminated just scanning before at diaphragm, very first time digitized image, the diaphragm after avoiding polluting loses break-up value; And can give picture number, very convenient inquiry and retrieval.
The technical scheme of the utility model is: a kind of online pollution index measuring diaphragm scanning shows storage system; The online pollution index measuring diaphragm of the coil paper formula device that comprises automatic rolling; It is characterized in that the measurement rear film of the online pollution index measuring diaphragm of coil paper formula device rolled-up above, be provided with using diaphragm to carry out the device and the video memory of pickup image.Said video memory is the video memory that has time-stamp; Diaphragm is once analyzed and is accomplished after behind the pickup image, the coil paper automatic rolling, and a new online pollution index measuring diaphragm gets into the measuring position and measures next time.
The beneficial effect of the utility model is: measure rear film in the past and rolled once more, after all measurement finished, measuring diaphragm was dropped.Even do not abandon, owing on the diaphragm residual organic matter etc. is arranged, can produce mould etc. and grow thing, there has not been break-up value.The coil paper diaphragm that the utility model system will measure after accomplishing absorbs at the device that does not also have the rolled-up pickup image of process before; As carry out optical scanning; Optical scanning or the compression of images after CMOS, CCD imaging are become the JPG file; And add the mode that the time mode adds passage according to the date and number (yy-mm-dd-hh-mm-ss-cc), the 3rd passage diaphragm of for example measuring in 10: 5: 50 morning of on February 1st, 2011 is just numbered into 20110201100550-03, is convenient to inquire about from now on.
File after the scanning is stored on storage card or other storage medium, on the display screen of instrument, can directly check, also can storage card be taken off the back and to computing machine, carefully check.Also there be not contaminated just scanning before at diaphragm, very first time digitized image, the diaphragm after avoiding polluting loses break-up value; Image is numbered, very convenient inquiry and retrieval; Picture storing not only can see in instrument itself on storage card, can also copy on the computing machine to examine.
Description of drawings
Fig. 1 is that a kind of online SDI analysis meter diaphragm scanning shows the storage system synoptic diagram.
Embodiment
In conjunction with accompanying drawing; Embodiment is explained as follows: a kind of online pollution index measuring diaphragm scanning shows storage system; The online pollution index measuring diaphragm of the coil paper formula device that comprises automatic rolling; On the rolled-up path of the measurement rear film of the online pollution index measuring diaphragm of coil paper formula device 12 (top), be provided with using diaphragm to carry out the device 3 and video memory 4 of pickup image.The 6th, without the diaphragm volume of measuring, the method for operation is following:
The online pollution index measuring diaphragm of the coil paper formula device of automatic rolling is driven by driving wheel 5, and driving wheel (by servomotor control) running is clockwise fixed to certain position; The measurement mechanism operation is measured, after about tens minutes; Measurement result is come out; Driving wheel is running clockwise once more, to the next position, so repeatedly.Measure the rolled-up top of rear film, through being provided with to using diaphragm to carry out in the device and image stored storer 4 of pickup image.
Utilize the measuring method of the utility model: in tens minutes that measure; Optical scanning system work (also can be CMOS, CCD digital camera or camera) stays the clock numeral on date automatically on every image according to the clock on date when obtaining image; Diaphragm is carried out image scanning, and the time is about 1 minute.After the scanning, picture storing on storage card, the line number of going forward side by side.
Claims (2)
1. an online pollution index measuring diaphragm scanning shows storage system; The online pollution index measuring diaphragm of the coil paper formula device that comprises automatic rolling; It is characterized in that the measurement rear film of the online pollution index measuring diaphragm of coil paper formula device rolled-up above, be provided with using diaphragm to carry out the device and the video memory of pickup image.
2. online pollution index measuring diaphragm scanning according to claim 1 shows storage system, it is characterized in that said video memory is the video memory that has time-stamp.
