Detailed ways

Below in conjunction with accompanying drawing, the utility model is described concretely;

As shown in Fig. 1, a kind of hydrocyclone slick oil collecting and discharging device of the present utility model comprises oily sewage collecting tank 1, is provided with a fast sedimentation separation chamber tank 5 in described oily sewage collecting tank 1, so The fast sedimentation separation chamber tank 5 is connected and fixed in the oily sewage collection tank 1 through the bottom plate, and the liquid cyclone separator 6 and the floating oil automatic collection device 3 are arranged in the described rapid sedimentation separation chamber tank 5. The hydrocyclone 6 is fixed in the fast sedimentation separation chamber tank 5 through a bracket. The hydrocyclone 6 is provided with an oily sewage inlet 61, a water outlet 62 and an overflow 63, and the floating oil collection and discharge device 3 is arranged above the hydrocyclone 6 , the oil slick collection and discharge device 3 is composed of a floating oil automatic collection floating plate 31 and a buoy 32, the bottom of the automatic floating oil collection floating plate 31 is provided with a sleeve type telescopic oil guide pipe 4, the described The sleeve-type telescopic oil guide pipe 4 passes through the hydrocyclone 6 and is connected to the dirty oil collection tank outside the oily sewage collection tank 1 .

As a preference of this embodiment, a U-shaped drainage pipe 2 is provided on the peripheral part of the rapid sedimentation separation chamber tank 5, which is used to quickly discharge the liquid in the lower part of the rapid sedimentation separation chamber tank 5. The chamber tank 5 is provided with a ventilation breaking pipe 8 on the U-shaped drain pipe 2, which is used to stop the U-shaped drain pipe 2 from draining, so as to maintain a constant water level in the rapid sedimentation separation chamber tank 5.

The working process of the utility model is: all kinds of oily sewage from oil refineries, oilfield produced water, ports, docks, oil depots, and irrigation areas enter the utility model quickly through a sewage delivery pump or through a variable-diameter sewage delivery pipe by a certain gravity. In the hydrocyclone 6 in the tank 5 of the sedimentation separation chamber, the oily sewage rotates at a certain speed in the hydrocyclone 6, and the difference in density between oil and water produces different centrifugal force fields, and the oily sewage is treated by centrifugal force. In the pretreatment of oil-water separation, the light-phase oil after hydrocyclone separation quickly floats up to the water surface of the fast-settling chamber tank 5 through the overflow port 63, and the floating oil arranged above the hydrocyclone 6 automatically The floating oil collection floating plate 31 is collected, and the floating oil automatic collection floating plate 31 is supported by the buoy 32 to float on the water surface. The hydrocyclone 6 passes through and is connected to the oily sewage collection tank 1 outside the sewage oil collection tank. At the same time, because the oily sewage can generate a secondary rising liquid flow in the hydrocyclone 6, the hydrocyclone The separator can not only separate the two mutually insoluble oil and water, but also accelerate the rapid sedimentation of the solid phase in the oil and water, and the water and solid phase are discharged from the water outlet 62 at the lower part of the hydrocyclone 6 to the rapid sedimentation separation chamber tank 5 Inside.

Compared with the oily sewage collection tank or oily sewage collection tank in the prior art, the utility model adopts a hydrocyclone separator and an automatic collection and discharge device for floating oil in the oily sewage collection tank, so the effect of centrifugal force can be used to achieve Good separation effect, can realize continuous operation of single tank, oil slick can be collected and discharged automatically, reduce investment, realize separation and pretreatment of oily sewage at the same time of sewage collection, can not only adjust the water volume, but also adjust the water quality, and reduce the pollution in the discharged water At the same time, by setting a U-shaped drain pipe and setting a vent breaker pipe on the U-shaped drain pipe, the water in the tank of the rapid sedimentation separation chamber can be discharged in time, and the water level can be guaranteed to achieve a constant water level to collect floating oil and ensure quality of sewage treatment.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model in any other form, and any modifications or equivalent changes made according to the technical essence of the utility model still belong to the utility model. Scope of protection claimed.
