The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Embodiment 1:
As shown in Figure 1, the discharging structure of subsider comprises cell body 1, charging aperture 11, on cell body 1 upper inside wall, is provided with ring flat-plate 3; At least be provided with a spout hole 4 on the ring flat-plate 3, present embodiment is 4 spout holes 4, and the inboard of ring flat-plate 3 is provided with riser 5; Cell body 1, ring flat-plate 3 and riser 5 have constituted groove, on the sidewall of cell body 1, are provided with a safe overfall 2 at least, and present embodiment is 2 safe overfalls 2; Safe overfall 2 arrives the height of bottom land greater than the height of ring flat-plate 3 to bottom land, is provided with a feed box 7 on the sidewall of cell body 1 at least, and present embodiment is 2 feed boxes 7; The sidewall of feed box 7 is provided with feed box charging aperture 6, and the bottom of feed box 7 is provided with discharge gate 10, and feed box charging aperture 6 is located on cell body 1 sidewall of ring flat-plate 3 tops; Be provided with pull bar 8 in the feed box 7, the bottom of pull bar 8 is provided with taper sprue 9, and feed box 7 tops are passed on the top of pull bar 7; The top of pull bar 8 is the T font, and discharge gate 10 is taper, and taper sprue 9 the widest part block discharge gate 10; Charging aperture 11 is located at the cell body 1 top center outside, and ring flat-plate 3 is positioned within the supernatant layer, and riser 5 tops are higher than in the cell body 1 the high liquid level (HLL) of clear liquid band.
Embodiment 2
The sidewall of the cell body 1 among the embodiment 1 is provided with 4 safe overfalls 2, and the sidewall of cell body 1 is provided with a feed box 7, and other is with embodiment 1.
The sidewall of the cell body 1 among the embodiment 1 is provided with 4 feed boxes 7, and the sidewall of cell body 1 is not established safe overfall 2, and other is with embodiment 1.
Spout hole among the embodiment 1 is 8.
Operation principle of the present invention: the supernatant layer of subsider is the superiors of subsider, and ring flat-plate 3 is located in the supernatant layer of subsider cell body 1, can guarantee that like this slip that overflow goes out is the clear liquid slip.The quantity of spout hole 4 needs to confirm according to spillway discharge with size.Safe overfall 2 highly is higher than the height of ring flat-plate 3, and slip can not flow out from safety overfall 2 when this can guarantee operate as normal.Riser 5 tops are higher than in the subsider cell body 1 the high liquid level (HLL) of clear liquid band, can prevent that like this foam that forms in the supernatant layer from flowing out from overfall 4.Feed box charging aperture 6 is the side-walls perforates at subsider cell body 1, and its extreme lower position must be concordant with ring flat-plate 3.The slip that the spout hole overflow goes out directly gets into feed box from feed box charging aperture 6, and feed box 7 welds together with subsider cell body 1.Feed lever 8 in the sub-tank 7, and it can move up and down, the tapered block 9 and La blocking lever 8 are connected together, which can move up and down with the rod, and the widest part of the tapered block block 9 can all block Living the discharge port 10.Discharging opening 10 is arranged in the bottom of feed box 7, and this helps being emptied completely the slip in the feed box 7.Slip gets into subsider cell body 1 from subsider charging aperture 11, and the solid particle of slip will be from down from the dense layer of sand of last formation, body refuse enriched layer, the beds of precipitation, supernatant layer behind the certain hour because of gravity effect free settling.When the supernatant layer liquid level was higher than ring flat-plate 3, the slip of supernatant layer got into the groove the inside that is made up of subsider cell body 1, ring flat-plate 3 and riser 5 from overfall 4 overflows, discharges from feed box charging aperture 6 and flow into 7 li of feed boxes.Under the normal condition, the taper sprue 9 that feed box is 7 li is being opened.So getting into the slip of feed box 7 just can successfully discharge from discharge gate 10.If discharge gate 10 can not all be discharged the slip that comes out from spout hole 4; When causing liquid level in the groove that material is made up of subsider cell body 1, ring flat-plate 3 and riser 5 to exceed the height of safe overfall 2, slip just can be discharged from safety overflow lip 2 and feed box charging aperture 6 respectively simultaneously.
