Description

Technical Field

[0001] The present invention belongs to the technical field of marine oil-water separation, and particularly relates to a partitioned marine oil-water separation mechanism. Background Art

[0002] At present, a large amount of oil is contained in marine wastewater. If it is directly discharged into rivers, lakes and seas, it will not only cause greater pollution, but also increase the difficulty of sewage treatment. At the same time, the oil contains many organic components, and direct discharge will cause waste of resources. Oil-water separation is mainly based on the density difference or different chemical properties of water and oil. The oil-water separation utilizes the principle of natural static gravity sedimentation to complete the separation of oil and water, so as to separate the oil and water in this way. However, in the existing separation devices, after static gravity sedimentation, generally, the oil is first extracted, and then the remaining water is discharged. Moreover, since the oil-water separation interface needs to be observed manually, when the oil is extracted, when reaching the oil-water separation interface, it is often necessary to observe manually. When the water is instantaneously extracted, it is necessary to stop, and only then can the oil extraction be completed, and then the drainage can be carried out. The operation of extracting oil first and then draining water is cumbersome. At the same time, the operator needs to observe the extraction process all the time, with a heavy workload, and the operation process is relatively cumbersome, resulting in low operation efficiency.

The lower end of the L-shaped guide pipe 51 is connected to the telescopic pipe 52. The lower end of the telescopic pipe 52 is installed with the oil drain pipe 53. The oil drain pipe 53 passes through the side of the separation chamber 11.

The side screw rod 44 rotatably passes through the longitudinal card slot 121. The side screw rod 44 is threadedly engaged with the side floating block 42. In this way, the first motor 43 drives the side screw rod 44 to rotate. The side screw rod 44 drives the side floating block 42 to move up and down.

Thus, by driving the central lead screw 72 to rotate by the second motor 73, the central lead screw 72 drives the central floating cylinder 71 to move up and down, and the central floating cylinder 71 drives the blocking plate to move up and down. To ensure the sealing performance, further, a central through hole is provided in the middle of the partition plate 3, and a central sealing ring 32 is provided on the central through hole; the central floating cylinder 71 is sealingly inserted through the central sealing ring 32.

[0022] As Figures 1 to 4 shown, to facilitate the discharge of the oil liquid, further, an oil discharge valve 531 is provided at the outer end of the oil discharge pipe 53. To facilitate the drainage, further, a drainage valve 81 is provided at the outer end of the drain pipe 8. To ensure the sealed oil-water stratification, further, sealing rings 22 are provided around the periphery of the closing plate 2; the peripheries of the sealing rings 22 are in sealing contact with the inner peripheries of the four sides of the separation tank 1. To facilitate the injection of the liquid to be stratified, further, an opening and closing cover 13 is provided at the upper end of the separation tank 1; the opening and closing cover 13 is openably and closably installed at the upper end of the separation tank 1.

[0023] In the present invention, the liquid to be separated is injected into the separation cavity 11, and then the liquid is allowed to stand and stratify. The oil body is located in the upper layer and the water body is located in the lower layer. Then, the closing drive mechanism 4 drives the closing plate 2 to move downward so that the closing plate 2 moves to the oil-water separation interface. A transparent observation glass strip can be provided on the side wall of the separation cavity 11 to ensure that the closing plate 2 moves in place. Then, the blocking power mechanism 7 drives the blocking plate 6 to seal and abut upward against the sealing opening 21 of the closing plate 2. Thus, the closing plate 2 and the blocking plate 6 are butted to form a closed isolation structure. The upper side of the closing plate 2 and the blocking plate 6 is the oil layer, and the lower side of the closing plate 2 and the blocking plate 6 is the water layer. Thus, by opening the drain pipe 8 for drainage and simultaneously discharging oil through the oil discharge pipe 53, drainage and oil discharge can be carried out simultaneously, and there is no need for the operator to observe continuously, reducing the operator's workload. After the separation and liquid discharge are completed, the closing plate 2 is reset upward and the blocking plate 6 is reset downward for the next liquid injection.
