As shown in fig. 1-7, the utility model provides an oil-water separator, include:

a liquid inlet 11 and an oil outlet 12 are arranged at the top of the tank body 1, and a water outlet 13 and a back flushing port (not shown) are arranged at the bottom of the tank body 1;

the separation bed 2, the separation bed 2 is set up in the tank 1;

the movable grid plate 3, the movable grid plate 3 includes: the plate body 31 in the movable grid plate 3 is arranged in the tank body 1 and is positioned below the separation bed 2 in a vertically sliding manner, wherein the plate body 31 is provided with a plurality of first mounting holes 311 and second mounting holes 312; a one-way valve 32 is arranged in each first mounting hole 311, the one-way valve 32 is used for enabling fluid to flow downwards from the upper part of the plate body 31, a back flushing mechanism 33 is arranged in each second mounting hole 312, and the back flushing mechanism 33 is positioned at the upper part of the second mounting holes 312 and used for spraying water above the plate body 31 in a pulse mode;

the oil absorption filler 4, the oil absorption filler 4 is used for absorbing the oil contained in the water, and the oil absorption filler 4 is arranged between the separation bed 2 and the movable grid plate 3.

Specifically, in the actual use process, the oil-water mixture enters the top of the tank body 1 through the liquid inlet 11, and the mixture entering the tank body 1 flows to the lower separation bed 2. The separating bed 2 is transversely arranged in the tank body 1, after the mixture passes through the separating bed 2, the water and the oil are separated from each other under the separating action of the separating bed 2, and meanwhile, the separated oil is combined with each other to form larger oil drops. The specific gravity of oil drops is lighter than that of water, so that the oil drops can rapidly rise and form an oil storage area at the top of the tank body 1, wherein the structure configuration of the conventional oil-water separator can be referred to in the oil-water separation mode of the separation bed 2, and is not limited or described herein.

The water separated by the separation bed 2 still contains a small amount of oil, the water continuously flows downwards to the oil absorption filler 4, the oil contained in the water is absorbed by the oil absorption filler 4 after the water is filtered by the oil absorption filler 4, and finally, the water flows to the bottom of the tank body 1 through the first mounting hole 311 on the movable grid plate 3 and is discharged to the outside of the tank body 1 through the water discharge port 13.

And as the service time increases, the oil absorbed in the oil absorption filler 4 is more and more, and the oil absorption capacity of the oil absorption filler 4 is gradually reduced. At this time, the oil-absorbing filler 4 needs to be squeezed through the movable grid 3, water is injected into the bottom of the tank body 1 through the back washing port, and the water pressure at the bottom of the tank body 1 is gradually increased and drives the movable grid 3 to move upwards due to the one-way valve 32 arranged in the first mounting hole 311 of the movable grid 3. The representation entity of the check valve 32 may adopt a structural form of a conventional technology, which is not described herein.

As shown in fig. 2, the movable grid 3 during the moving process will squeeze the oil absorbing filler 4 so that the oil absorbing filler 4 is sandwiched between the movable grid 3 and the separation bed 2, and the oil in the oil absorbing filler 4 is squeezed out. Meanwhile, the back washing mechanism 33 sprays water in a pulse manner to the upward oil absorption filler 4 under the action of the bottom water pressure, so that the oil absorption filler 4 is efficiently cleaned to remove oil in the oil absorption filler 4, the oil absorption filler 4 recovers the efficient oil absorption capacity, and the service life of the oil absorption filler 4 is effectively prolonged.

Since there is still a large amount of oil-water mixture above the movable grid 3, the oil will float to the top of the tank 1. After the backwashing opening is decompressed or the water outlet 13 is opened, the movable grid plate 3 is gradually lowered, the oil absorption filler 4 is gradually expanded after releasing pressure, and in the expansion process, the oil absorption filler 4 absorbs a large amount of water and a small amount of oil, so that the oil absorption filler 4 recovers the filtering capacity again.

Further, in order to perform effective backwashing treatment on the oil-absorbing packing 4 by the backwashing mechanism 33, the backwashing mechanism 33 includes a sleeve 331, a rotating member 332, and an upper cover 333;

Specifically, when water is injected into the bottom of the tank 1 to squeeze the oil-absorbing packing 4 through the movable grill 3, the water in the bottom of the tank 1 enters the sleeve 331 through the second mounting hole 312 and flows from the plurality of spiral water grooves 3323. In the flowing process of the water in the spiral water groove 3323, on one hand, the water is sprayed upwards through the spiral water groove 3323 and through the hollow structure of the upper cover 333, and on the other hand, the spiral water groove 3323 applies a balanced torsional force to the rotating part 332, so that the rotating part 332 rotates stably.

And the rotating member 332 may rotate a portion in the sleeve and may move up and down with respect to the upper cover 333. During the rotation of the rotating member 332, the rotating member 332 will move towards the upper lid 333 due to the action of the bottom water pressure, and during the rotation of the rotating member 332, the hemisphere 3324 will be intermittently pressed by the convex structure 3332, so that the rotating member 332 is close to the first cantilever. In the process that the rotating member 332 approaches the first suspension arm, the lower port of the through hole 3320 is gradually blocked by the first suspension arm, so that the through hole 3320 cannot spray water outwards. After the hemisphere 3324 leaves the convex structure 3332, the rotating member 332 is separated from the first cantilever by the water pressure, the interval between the first cantilever and the through hole 3320 is gradually increased, and part of the water flowing through the sleeve 331 further flows into the through hole 3320 and is sprayed out from the upper port of the through hole 3320, so that the water is sprayed out along the axis of the second rotating shaft 3322.

During actual use, as the movable grid moves upwards, each backwashing mechanism 33 continuously sprays water upwards through the spiral water grooves 3323 to clean the oil in the oil absorbing filler 4. Simultaneously, the perforating hole 3320 then realizes the outside water spray of pulsed, utilizes the water spray of pulsed to handle, can produce the impact to oil absorption filler 4 to clear up stubborn oil on oil absorption filler 4 more effectively, pack 4 with the realization more effective clean oil absorption.
