Among the figure, 1-gland lining; The 2-filter disc; The 3-cup; The 4-dividing plate; The 5-sealing gasket; The 6-level switch; The import of 7-water sample; The import of 8-rinse water; The 9-screw; The 10-overflow vent; 11-gland lining floss hole; The last cup floss hole of 12-; The import of 13-lower cup body rinse water; 14-lower cup body floss hole; The 15-sample tap.
Embodiment
Fig. 1 is the utility model structural representation, and Fig. 2 is the utility model decomposition texture synoptic diagram.The on-line automatic filtration unit of a kind of as seen from the figure cup type water sample, comprise gland lining 1, cup 3 and filter disc 2, it is characterized in that: the top of described gland lining 1 is equipped with water sample import 7 and rinse water import 8, level switch 6 is fixedlyed connected with gland lining 1 top, and gland lining 1 upper end one side has overflow vent 10, lower end one side that gland lining floss hole 11 is arranged; The dividing plate 4 of fixedlying connected with described cup 3 medial surfaces around cup 3 middle parts are equipped with, described dividing plate is last cup more than 4, dividing plate is lower cup body below 4, the permeable hole that axially is equipped with on the dividing plate 4 is communicated with goes up cup and lower cup body, described cup lower end one side that goes up has last cup floss hole 12, the described identical coupling of external diameter that goes up the internal diameter and the described gland lining 1 of cup, described upward cup floss hole 12 is corresponding consistent with the position bore of described gland lining floss hole 11, and the lower cup body upper side has import 13 of lower cup body rinse water and ventilation mouth, lower end side has sample tap 15, the lower end, center is a lower cup body floss hole 14; Be equipped with filter disc 2 between the edge, lower end of dividing plate 4 tops and gland lining 1.
Described filter disc 2 can be the filtering material of any sheet, as filter paper, filter membrane, filter screen etc.
Be equipped with sealing gasket 5 between the edge, lower end of described filter disc 2 and gland lining 1.
Described gland lining 1 is connected along screw thread 9 with the described cup end edge that goes up.
Below be example with the utility model of being applied to the water quality online auto monitoring system, be further described.The utility model mainly is made of gland lining 1, level switch 6, filter disc 2 and cup 3, and is whole cylindrical.Cup 3 and gland lining 1 are made by the moulding of high-quality high strength anti soda acid organic glass, cup 3 internal diameters are 130mm, the external diameter of gland lining 1 is 125mm, all pipe fitting joints all adopt the commercially available high-quality plastics joint of 6mm, adopting one deck diameter is that the middling speed quantitative filter paper of 125mm is as filter disc 2, seal with ring plate shape rubber gasket 5 between the end of filter paper and gland lining 1, be threaded when fastening with four 6mm hand screws between gland lining 1 and the cup 3, just form good sealing effectiveness between dividing plate 4, filter paper 2, sealing gasket 5 and gland lining 1 end.All water sample imports or rinse water import, each floss hole connect respective valves respectively, are connected with the lower cup body bleed valve as lower cup body floss hole 14, and whether water sample discharges and controlled by described bleed valve.
During device work, water sample enters gland lining 1 inside from water sample import 7, and the liquid level when gland lining 1 inside rises, and the float that promotes level switch 6 arrives the switch height in limited time, stops sample introduction.The height of level switch 6 is spacing can to carry out manual shift as required in advance and fixes, and with control sample introduction total amount, guarantees that the water yield satisfies the analytical test needs and is unlikely to too much redundant again.Water and water-soluble substances in the gland lining 1, infiltration filter disc 2 under the effect of self gravitation, permeable hole by dividing plate 4 flows into and is stored in the lower cup body, and insoluble particle thing such as silt and suspension are then held back by filter disc 2 in the water sample, thereby reaches the purpose of filtration.When the float of level switch 6 along with gland lining 1 in the decline of water level arrive switch down in limited time, filtration is finished.Water sample after the filtration can directly use for analytical test by the sample tap 15 of cup 3 belows.After sampling finishes, the lower cup body bleed valve is opened, remaining water sample is discharged from lower cup body floss hole 14, simultaneously, cleaning water valve, last cup bleed valve are opened, rinse water enters gland lining 1 inside from rinse water import 8, and flows out from gland lining floss hole 11 and last cup floss hole 12, thereby forms the cleaning to gland lining 1 inside and filter disc 2.Rinse water enters lower cup body from lower cup body rinse water import 13, and flows out from lower cup body floss hole 14, thereby forms the cleaning to lower cup body, and cleaning finishes, and cleans water valve, last cup bleed valve and lower cup body bleed valve and closes successively, and whole periodic process finishes.
