[0036] In a specific case of this embodiment, the sewage discharge structure includes a storage box 21, a supporting cover 22 and a discharge unit. The storage box 21 passes through the tank body 1. A discharge window 28 is provided on the side of the storage box 21 away from the filter plate 18. The discharge window 28 is connected to the storage box 14.

[0037] In another specific case of the present embodiment, the discharge unit includes a slide plate 23, a movable arm 24 and a reciprocating screw 25, and the driving assembly includes at least an air transmission component. The slide plate 23 is movably arranged in the storage box 21, the movable arm 24 is movably arranged on the storage box 21 and connected to the slide plate 23, the reciprocating screw 25 is movably arranged between the mounting platform 17 and the storage box 21, the reciprocating screw 25 slides through the movable arm 24 and the reciprocating screw 25 and the movable arm 24 are threadedly matched, the air transmission component is arranged on the mounting platform 17 and connected to the reciprocating screw 25, the air transmission component is connected to the exhaust pipe 13, and the exhaust pipe 13 controls the rotation of the reciprocating screw 25 when inputting air into the air transmission component.

[0040] In actual application, after the mist generated in the separation zone is processed by the mist water treatment box 6, the gas is finally discharged from the mist water treatment box 6 into the exhaust pipe 13, and the oil input into the impurity removal zone can be initially filtered through the filter plate 18, and the solid impurities mixed in the oil can be left on the surface of the filter plate 18, and the drive component is controlled by the control center 4 to work.

During the continuous extension and retraction of the cylinder 30, the pull arm 19 and the impurity removal plate 20 can be driven. It reciprocates along the surface of the filter plate 18, and thus can push the impurities on the surface of the filter plate 18 into the storage box 21. Since the exhaust pipe 13 and the drive box 26 are connected, the collision between the gas and the drive vane 27 can drive the drive vane 27 to rotate, thereby controlling the rotation of the reciprocating screw 25. When the reciprocating screw 25 rotates, it can drive the movable arm 24 and the slide plate 23 to reciprocate in the storage box 21, and then discharge the impurities in the storage box 21 into the storage box 14, completing the preliminary filtration of the oil and the self-cleaning of the surface of the filter plate 18.

[0041] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the auxiliary oil discharge assembly includes a drive plate 11, a water pusher plate 12, a gear 32 and a rack 29.

[0043] In another specific case of the present embodiment, the vacuum structure includes a vacuum cylinder 31, a piston 35, a vacuum hole 36, a hose 40, a sealing rod 37 and a second through groove 38. The vacuum cylinder 31 is arranged on the mounting platform 17, the piston 35 is movably arranged in the vacuum cylinder 31 and the two are elastically connected, the vacuum hole 36 is arranged on the vacuum cylinder 31 and is connected to the cylinder 30 through the hose 40, the sealing rod 37 is movably arranged in the second through groove 38 formed on the vacuum cylinder 31, the sealing rod 37 is connected to the piston 35, and the sealing rod 37 is connected to the connecting piece.

[0044] It should be noted that the connecting member includes a connecting head 39, a winding disk 33 and a connecting belt 34. The connecting head 39 is arranged on the sealing rod 37. The winding disk 33 is movably arranged on the mounting frame 15 and is coaxially connected to the gear 32. The connecting belt 34 is wound on the winding disk 33 and the free end of the connecting belt 34 is connected to the connecting head 39.

[0045] Without limitation, the power element may be a stepper motor 16 or a servo motor. In the present embodiment, the power element is preferably a stepper motor 16, and the stepper motor 16 is disposed on a mounting bracket 15. As for the specific model parameters of the stepper motor 16, the best selection can be made according to the actual situation, and no specific limitation is made here.

[0046] In actual application, the control center 4 controls the stepper motor 16 to rotate reciprocatingly, thereby driving the gear 32 to rotate reciprocatingly. During the reciprocating rotation of the gear 32, due to the meshing between the gear 32 and the rack 29, the rack 29 and the driving plate 11 can be driven to reciprocate in the horizontal direction along the first groove 9, thereby driving the water pusher plate 12 to reciprocate in the separation area, thereby pushing the oil on the liquid surface of the separation area into the oil discharge area.

In the process of winding and releasing the connecting belt 34, the connecting head 39, the sealing rod 37 and the piston 35 can be driven to reciprocate along the vacuum cylinder 31, thereby controlling the continuous expansion and contraction of the cylinder 30 by changing the gas volume inside the vacuum cylinder 31. During the expansion and contraction of the cylinder 30, the impurity removal plate 20 is driven to move, thereby discharging impurities on the surface of the filter plate 18 into the storage box 21.

[0047] How this application works:

[0048] The oil is input into the impurity removal area, and the oil falling into the impurity storage area can be preliminarily filtered through the filter plate 18. The filtered oil slowly enters the separation area through the liquid steady flow baffle 7. The oil in the separation area is settled, and the water and oil are arranged in layers. The water is discharged along the drain pipe 10 and the drain head 5. The mist generated in the separation area is treated by the mist water treatment box 6, and finally the gas is discharged from the mist water treatment box 6 into the exhaust pipe 13. The oil input into the impurity removal area can be preliminarily filtered through the filter plate 18. The solid impurities mixed in the oil can be left on the surface of the filter plate 18. The stepper motor 16 is controlled by the control center 4 to reciprocate, thereby driving the gear 32 to reciprocate. During the reciprocating rotation of the gear 32, due to the meshing between the gear 32 and the rack 29, the rack 29 and the drive plate 11 can be driven to reciprocate in the horizontal direction along the first through groove 9, thereby driving the water push plate 12 to reciprocate in the separation area, thereby pushing the oil on the liquid surface of the separation area into the oil discharge area. At the same time, the stepper motor 16 can also drive the reel 33 to rotate back and forth, thereby continuously reeling and releasing the connecting belt 34. In the process of reeling and releasing the connecting belt 34, the connecting head 39, the sealing rod 37 and the piston 35 can be driven to reciprocate along the vacuum cylinder 31, thereby controlling the continuous expansion and contraction of the cylinder 30 by changing the gas volume inside the vacuum cylinder 31. In the process of continuous expansion and contraction of the cylinder 30, the pulling arm 19 and the impurity removal plate 20 can be driven to reciprocate along the surface of the filter plate 18. The impurities on the surface of the filter plate 18 can be pushed into the storage box 21. Since the exhaust pipe 13 and the drive box 26 are connected, the collision between the gas and the drive vane 27 can drive the drive vane 27 to rotate, thereby controlling the rotation of the reciprocating screw 25. When the reciprocating screw 25 rotates, it can drive the movable arm 24 and the slide plate 23 to reciprocate in the storage box 21, thereby discharging the impurities in the storage box 21 into the storage box 14, completing the preliminary filtering treatment of the petroleum and the self-cleaning work on the surface of the filter plate 18.
