[0041] The continuous discharge assembly 6 is arranged inside the drain pipe 4 , and is used to maintain the drainage pipe 4 unobstructed when the filter plate 5 is removed and replaced.

[0042] When the intelligent oil removal and filtration device for oil production wastewater is used, the wastewater is passed from the water inlet pipe 2 into the processing box 1 and is left to stand, so that the oil and water in the wastewater are separated, and then the oil absorption component 3 is operated, and the oil absorption component 3 fully absorbs and discharges the oil on the surface of the wastewater to achieve the effect of oil-water separation, and the oil absorption component 3 can accurately control the oil absorption position according to the amount of water content, so as to achieve complete absorption of the oil and avoid residual oil from flowing into the subsequent process. After the oil absorption is completed, the drain pipe 4 is opened to allow the wastewater after oil absorption to enter the coherent discharge component 6 to filter the wastewater. During the filtering process, if the filter plate 5 is blocked, it will lead to poor flowability. The flow direction of the wastewater can be adjusted through the coherent discharge component 6 to ensure that the wastewater can flow out and filter through the other side. At this time, the filter plate 5 can be replaced to ensure the smoothness of the wastewater filtration without interrupting the process, which is more convenient to use, and the coherent discharge component 6 can automatically change the fixed state of the filter plate 5 when adjusting the flow direction, making the operation more convenient.

[0046] As shown in FIG. 1 , in the embodiment of the present invention, a condenser pipe 38 is installed on the inner wall of the processing box 1 , and the condenser pipe 38 cooperates with the oil pump 35 .

[0047] When in use, the wastewater is directly introduced into the treatment box 1 and allowed to stand to separate the oil and water. Since the density of the polyethylene separation plate is 0.94-0.96 g / cm3, and the density of water and oil is 1 g / cm3 respectively, 3 and 0.71-0.84g / cm 3 Therefore, the polyethylene separation plate 33 will float between the water and the oil. At this time, the oil pump 35 is driven to operate, and the oil pump 35 can extract the oil through the oil suction pipe 34 and the connecting pipe 36, and discharge it through the oil discharge pipe 37 to achieve the oil removal operation. Since the polyethylene separation plate 33 floats above the water, it will not absorb water, but only absorb the oil on the water surface.

[0061] The second bevel gear 620 is rotatably connected to the interior of the partition block 63 , and a second transmission belt 621 is sleeved between the second bevel gear 620 and the linkage plate 617 .

[0062] When in use, after the waste water passes through the drain pipe 4, it will enter the first water pipe 61 or the second water pipe 62 according to the state of the water guide plate 66, as shown in Figure 1. At this time, the water guide plate 66 completely blocks the first water pipe 61, and the waste water will directly enter the second water pipe 62 and be filtered through the filter plate 5 in the second water pipe 62.

[0063] When the filter plate 5 in the second water pipe 62 is blocked, the control motor 614 is driven, and the control motor 614 drives the first bevel gear 615 to rotate, and drives the linkage column 65 to rotate through the first transmission belt 616, so that the water guide plate 66 changes state and blocks the second water pipe 62, and the water flow will flow into the first water pipe 61 through the water guide plate 66.

[0064] During the rotation of the first bevel gear 615, the interlocking plate 617 is driven to rotate synchronously through the second bevel gear 620 and the second transmission belt 621, and then the screw 611 is driven to rotate synchronously through the cooperation relationship between the guide block 618 and the guide groove 619. Then, under the control of the threaded sleeve 613, the screw 611 in the first water pipe 61 will descend and enter the positioning hole 612 to fix the filter plate 5, and under the control of the threaded sleeve 613, the screw 611 in the second water pipe 62 will rise and disengage from the positioning hole 612, then the filter plate 5 is released and can be directly pulled out for cleaning or replacement.

[0065] This method is more convenient to use, can ensure that the flowability of the wastewater is not affected, and there is no need to stop the process when replacing the filter plate 5. It can always ensure the effect of wastewater filtration, is more convenient to operate, has a good filtration effect, and has high work efficiency.

[0066] In summary, when the intelligent oil removal and filtration device for oil production wastewater is used, the wastewater is passed from the water inlet pipe 2 into the processing box 1 and is left to stand, so that the oil and water in the wastewater are separated, and then the oil absorption component 3 is operated, and the oil absorption component 3 fully absorbs and discharges the oil on the surface of the wastewater to achieve the effect of oil-water separation, and the oil absorption component 3 can accurately control the oil absorption position according to the amount of water content, so as to achieve complete absorption of the oil and avoid residual oil from flowing into the subsequent process. After the oil absorption is completed, the drain pipe 4 is opened to allow the wastewater after oil absorption to enter the coherent discharge component 6 to filter the wastewater. During the filtering process, if the filter plate 5 is blocked, it will lead to poor flowability. The flow direction of the wastewater can be adjusted through the coherent discharge component 6 to ensure that the wastewater can flow out and filter through the other side. At this time, the filter plate 5 can be replaced to ensure the smoothness of the wastewater filtration, without interrupting the process, and it is more convenient to use. The coherent discharge component 6 can automatically change the fixed state of the filter plate 5 when adjusting the flow direction, making the operation more convenient.
