For achieving the above object; The technical scheme that adopts is: a kind of box water sample on-line filtration device; Comprise settling pit, place the spray thrower of said desilting cell cavity inner top, place the injection port and the drain valve of said settling pit bottom, it is characterized in that: said settling pit center lumen inwall is equipped with the supporting step of box filter; Its upper surface is connected with the bottom surface of box filter, and the shape and size of the outer peripheral face of said box filter and said settling pit inner peripheral surface are complementary.
Said box filter is equipped with by upper cover, upper screen, box-frame filter course, lower screen, capping down from top to bottom successively; And be connected in series fixing by screw rod and nut; The bore of said screw rod and screw hole coincide, and are equipped with permeable hole in said upper cover and the following capping.
Be equipped with sealing gasket respectively between said upper cover, upper screen, box-frame filter course, lower screen, the following capping and between the lower surface of capping down and the said desilting cell cavity internal support step upper surface.
Said upper screen and lower screen are 500 order silk quality foams.
The built-in 300 order quartz sands of said box-frame filter course.
The steady pin that the lower surface of said down capping is equipped with support step on pinhole inserted the connection.
Said sealing gasket is the rubber material.
The utlity model has following advantage:, can obtain significant turbidity and eliminate effect through selecting for use of multistorey strainer mesh and the box-frame filter course that loads filtering material; The particulate filter material of filling is easy to clean in the box-frame filter course, can be through top-down spray Cleaning for High Capacity and the cleaning of aeration from bottom to top, with the particle that is trapped and suspension wash-out easily; Adopt the fixing mounting means of latch, be easy to remove and install, easy maintenance is quick.
Description of drawings
Below in conjunction with description of drawings and embodiment the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is box filter decomposition texture sketch map.
Among the figure, the 1-spray thrower; The 2-settling pit; The box filter of 3-; The 4-injection port; The 5-drain valve; 6-supports step; The 7-handle; The 8-upper cover; The 9-sealing gasket; The 10-upper screen; 11-box-frame filter course; The 12-lower screen; Capping under the 13-; The 14-steady pin; The 15-nut; The 16-screw rod.
The specific embodiment
Fig. 1 is the utility model structural representation; By the visible a kind of box water sample on-line filtration device of figure; Comprise settling pit 2, place the spray thrower 1 of said settling pit 2 chamber inner tops; Place the injection port 4 and drain valve 5 of said settling pit 2 bottoms; It is characterized in that: said settling pit 2 center lumen inwalls are equipped with the supporting step 6 of box filter 3, and its upper surface is connected with the bottom surface of box filter 3, and the shape and size of the outer peripheral face of said box filter 3 and said settling pit 2 inner peripheral surfaces are complementary.
Fig. 2 is box filter decomposition texture sketch map; Illustrating said box filter is equipped with by upper cover 8, upper screen 10, box-frame filter course 11, lower screen 12, capping 13 down from top to bottom successively; And be connected in series fixing by screw rod 16 and nut 15; The length of screw rod 16 is decided according to the combined altitudes of whole device, and nut 15 is advisable with following capping 13 surfaces with the not outstanding upper cover 8 in screw rod 16 two ends when tightening up with screw rod 16.The bore of said screw rod 16 and screw hole bore coincide, and to guarantee the sealing effectiveness of whole device, are equipped with permeable hole in said upper cover 8 and the following capping 13.
Said upper cover 8, upper screen 10, box-frame filter course 11, lower screen 12, be equipped with sealing gasket 9 respectively between the capping 13 and between the lower surface of capping 13 down and said settling pit 2 chamber internal support step 6 upper surfaces down.
Said upper screen 10 is 500 order silk quality foams with lower screen 12.
Said box-frame filter course 11 built-in 300 order quartz sands.
The steady pin 14 that the lower surface of said down capping 13 is equipped with support step 6 on pinhole inserted the connection.
Said sealing gasket is the rubber material.
Settling pit 2, upper cover 8, capping 13 down, and the box-frame of said box-frame filter course 11 is formed by high-quality PVC plate forming.Screw rod is the high-quality stainless steel material.Settling pit 2 keeps to the side to be equipped with respectively handle 7 with box filter 3 upper surface both sides.During use; Box filter can carried and shake hands 7 by as after Fig. 2 built-up sequence seal combination, the steady pin 14 under whole box filter 3 is passed through on capping 13 bottom surfaces; Insert in the pin-and-hole corresponding on the settling pit 2 chamber internal support steps 6; And firmly compress downwards, rely on the weight of box filter 3 self and the sealing gasket of bottom, form the better seal effect between said box filter 3 and the supporting step 6.
Water sample from 4 entering of settling pit 2 injection ports; Rise along with water level; Pass through the permeable hole of permeable hole, lower screen 12, filtering material, upper screen 10 and the upper cover 8 of capping 13 down successively; Water and solubility determinand arrive the top of said box filter 3, and most particle and suspension are held back by the box-frame filter course in the water sample, thereby reach the purpose of isolated by filtration.Through selecting different filtering materials, can control different filter effects.
After finishing from setting pot 2 sampling, the drain valve 5 of settling pit 2 is opened, and will remain the water sample emptying; Inject the running water that pressurizes subsequently on the settling pit 2 in the spray thrower 1 from top to bottom to carrying out reverse spray Cleaning for High Capacity, rinse water is outwards discharging simultaneously, can also feed compressed air if needed from setting pot 2 belows filtering material is carried out the aeration cleaning; Filling is particulate filter material 300 order quartz sands in the box-frame filter course 11; During cleaning, the graininess individuality of filtering material can stir, and therefore cleans through top-down spray Cleaning for High Capacity and aeration from bottom to top; Be retained in the particle and the suspension on filtering material surface, can be by wash-out easily.
