Description

Case type no-power dynamic oil-water separating device

The utility model relates to a kind of oil conte, sewage treatment device, particularly the gravity method separating device.

According to national pollution exhaust criteria regulation, sewage with oil concentration must be lower than 10 mg/litre, so oily(waste)water must just can discharge through the oily water separation processing.Gravitational separation process is a kind of elementary means of oily water separation, equipment commonly used has parallel flow intercepter API, flat oil trap PPI and ripple inclined plate grease pond CPI, the common ground of this kind equipment be only in hydrostatic working efficiency just the highest, so when the oily(waste)water quantity discharged is very big, must build the considerable equalizing tank of some volumes or a plurality of oil traps are taken turns to operate, this initial cost and floor space that will increase engineering strengthens cost of investment, its complex structure of while, safeguard the cleaning difficulty, running cost is also higher.

The purpose of this utility model provides a kind of little box unpowered dynamic oil water separation device of few investment that takes up an area of.

The utility model is its upper center to be installed have the oil separating plate of a fluid inlet at casing front end formation settling pocket between the front end two side of casing, at fluid inlet between the two side, back of oil separating plate a water-stop sheet that has a water-in below it is installed with upper/lower positions and forms plenum chamber, fluid inlet is placed one group of barretter that vertically distributes with upper/lower positions in plenum chamber, connecting a consistent end with flow direction in the upper end of water-stop sheet is inclined upwardly and the spreader plate corresponding with the fluid inlet position, a downward-sloping following current plate is installed below spreader plate on the water-stop sheet, inboard below the following current plate to an acclivitous vortex board is installed between the two side of casing end, an adverse current adjustable plate that tilts above the casing end is installed between the two side below the following current plate before the vortex board, on the vortex board near casing terminal with an oil reservoir adjustable plate be installed below the fluid inlet correspondence position converge the grease chamber terminal formation of casing, on the box body wall of remittance grease chamber, have an oil outlet, on vortex board lower box rear wall, have a water outlet.

The utility model specific embodiment accompanying drawings is as follows:

The three-dimensional sectional view of Fig. 1 oily-water seperating equipment.

Fig. 2 embodiment 2 three-dimensional sectional views.

Embodiment 1:

As shown in Figure 1, at the front end of casing 1 oil separating plate 3 that has fluid inlet 2 is installed and is formed settling pocket, its bottom is back taper, in its bottom a silt sewage draining exit 5 that has control valve 4 is housed, one of the following installation of fluid inlet has the water-stop sheet 7 formation plenum chambers of water-in 6 behind the oil separating plate, to the water-stop sheet two ends stabilier 8 can be installed respectively also on the fluid inlet both sides and form the beloid plenum chamber of opening expansion gradually, fluid inlet is installed one group of barretter 9 that vertically distributes with upper/lower positions in the plenum chamber, the barretter cross section can be as the hexagon among the figure or tetragon or trilateral etc., hinged one is tilted and the spreader plate 10 corresponding with the fluid inlet position to the back upper place in water-stop sheet upper end, but the spreader plate end makes the spreader plate up-down adjustment to regulate liquid level by be connected adjusting leading screw 11 with its hinged suspension rod, the other end of regulating leading screw is installed on across in the hanging beam on casing 12, a downward-sloping following current plate 13 is installed below spreader plate on the water-stop sheet, inboard, following current plate below to casing end is equipped with an acclivitous vortex board 14, a hinged adverse current adjustable plate 15 that tilts to casing end top between the two side under the following current plate before the vortex board, its upper end is rotatably connected by the suspension rod hinged with it 16 and regulates leading screw 17, the other end of regulating leading screw is installed on across in the hanging beam on casing 18, on the vortex board near casing terminal with an oil reservoir adjustable plate 19 be installed below the inflow port correspondence position converge the grease chamber terminal formation of casing, an auxiliary adjustment plate 20 is installed on the oil reservoir adjustable plate, the auxiliary adjustment plate be rotatably connected across the end of the adjusting leading screw 22 in the hanging beam on casing 21, on the box body wall of remittance grease chamber, have an oil outlet 23, on vortex board lower box rear wall, have a water outlet 24, whole box body can be placed on the ground by support 25, also can directly be placed in the subsurface side bilge.Oily(waste)water during use after grid is removed the macrobead suspended substance is introduced into settling pocket, enter plenum chamber through fluid inlet 2 again, oil droplet floats on the liquid level top layer and forms the oily water separation layer under the effect of barretter and stabilier, because liquid level is opened to expand gradually flow velocity is reduced simultaneously, liquid is stable gradually after spreader plate flows into the disengaging zone, the water of bottom water-in on water-stop sheet flows into bottom half simultaneously, the oil on top layer enters the remittance grease chamber through the oil reservoir adjustable plate and reclaims through the oil outlet outflow, can suitably regulate the height of auxiliary adjustment plate 20 according to core intersection, water in the disengaging zone is stopped by the oil reservoir adjustable plate to reflux to stop by the adverse current adjustable plate that secondary refluxes downwards downwards along vortex board and turns to laggardly to go into the casing bottom and flowed out by water outlet 24 through two 180 degree, its oleaginousness of sewage of handling through above-mentioned tripping device reaches or near emission standard, the water of discharging again after filtration even depth handle and can discharge, can open control valve 4 as the silt in the settling pocket when too much dirt is discharged.

Embodiment 2:
