[0031] The beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, the sewage discharge volume and the incoming volume maintain a dynamic balance. When the oil rises, an axis is formed in the sewage and coincides with the axis of the fixed cylinder in a conical area. When the sewage flows out through the drainage pipe structure, the oil will not follow the sewage to flow out, but will continue to move upward and eventually gather and condense on the sewage surface to form an oil floating area. When the surface height of the oil floating exceeds the oil hole, the oil floating will flow from the oil hole to the diverter plate and be discharged through the oil drainage pipe structure, thereby achieving the purpose of removing the oil. When the stirring structure rotates forward, a columnar mixing area is formed at the bottom of the fixed cylinder, so that the oil on the surface of the particulate impurities interacts fully with the bubbles, so that the oil on the surface of the particulate impurities is separated from the particulate impurities. The sewage and particulate impurities in the columnar mixing area flow through the water hole into the separation mechanism, and the separation mechanism separates the particulate impurities in the sewage. The above work is repeated to separate the oil and particulate impurities in the sewage.

[0033] 2. In the present invention, before the power mechanism drives the inflating cylinder to rotate in the opposite direction, the circular plate structure is abutted against the lower end of the connecting cylinder, the lower opening of the connecting cylinder is blocked, and the sewage enters the funnel through the water hole and enters the connecting cylinder through the lower outlet of the funnel. After the No. 1 seal has blocked the water hole, the distance between the fixed ring and the circular plate structure reaches the maximum. At this time, the scraping structure is abutted against the lower surface of the filter element, and the No. 2 seal is abutted against the lower opening of the funnel, blocking the lower opening of the funnel, driving the circular plate structure to move upward, increasing the sewage pressure, and causing the sewage to move upward through the filter element and The sewage is discharged through the outlet pipe structure, and the particulate impurities are blocked by the filter element in the connecting cylinder, thereby realizing the separation of the particulate impurities in the sewage; when separating the particulate impurities, the scraping structure scrapes the particulate impurities on the surface of the filter element to prevent the particulate impurities from hindering the flow of sewage through the filter element; after the sewage in the connecting cylinder is completely discharged, the scraping structure is made to contact with the surface of the circular plate structure, driving the sliding frame to move downward to the lowest position, and the scraping structure drives the particulate impurities on the circular plate structure to rotate, so that the particulate impurities generate centrifugal force, so that the particulate impurities leave the circular plate structure, and the particulate impurities on the circular plate structure are cleaned.

[0034] 3. In the present invention, the No. 4 motor drives the No. 1 threaded shaft to rotate, drives the limit piece to move, so that the limit structure is abutted in the annular limit groove, and the relative height of the connecting shaft and the sliding frame remains unchanged, so that the fixed ring is abutted on the surface of the circular plate structure; the No. 4 motor drives the No. 1 threaded shaft to rotate in the opposite direction, drives the limit piece to move in the opposite direction, so that the limit structure is disengaged from the annular limit groove, and under the action of the elastic force of the No. 1 elastic piece, the connecting shaft moves upward, so that the distance between the fixed ring and the circular plate structure reaches the maximum.

[0035] 4. In the present invention, when there are many particulate impurities, after the sewage in the connecting cylinder is completely discharged, there is a distance between the fixed ring and the circular plate structure. When the limiting member moves, the limiting structure abuts against the annular slope structure. The limiting structure exerts a force on the annular slope structure, causing the annular slope structure to move downward, causing the connecting shaft to move downward, causing the limiting structure to finally abut against the annular limiting groove, causing the scraping structure to abut against the circular plate structure, thereby improving the adaptability of the separation mechanism.

[0036] 5. In the present invention, when the inflator starts to rotate in the reverse direction, when the connection between the spiral part and the upper annular part rotates to the driving part position, the driving part enters the spiral part, causing the driving part to move downward. When the connection between the spiral part and the lower annular part rotates to the driving part position, the driving part enters the lower annular part, the No. 1 sealing part moves to the lowest position, the No. 1 sealing structure disengages from the water hole, and the water hole is opened. After the water hole opening time reaches the set value, the inflator starts to rotate forward, when the connection between the spiral part and the lower annular part rotates to the driving part position, the driving part enters the lower annular part, the No. 1 sealing part moves to the lowest position, the No. 1 sealing structure disengages from the water hole, and the water hole is opened. When the No. 1 seal moves to the highest position, the upper surface of the No. 1 sealing structure is in contact with the water hole to seal the water hole; when the No. 1 seal moves to the highest position, the upper surface of the No. 1 sealing structure is coplanar with the bottom surface of the fixed cylinder, preventing granular impurities with oily dirt from accumulating in the water hole, and preventing granular impurities with oily dirt from directly entering the connecting cylinder.

DETAILED DESCRIPTION

[0056] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0057] like Figures 1-17 As shown, a separation and treatment device for oily wastewater includes a fixed cylinder 1, an air filling cylinder 2, a power mechanism 3 and a separation mechanism 4;

[0058] The separation mechanism 4 is connected to the fixed cylinder 1 above; a trumpet-shaped diverter plate 61 is fixed in the fixed cylinder 1; an oil hole 611 is provided in the middle of the diverter plate 61; a water inlet pipe structure 11, an oil discharge pipe structure 12, and a water drain pipe structure 13 are provided on the side wall of the fixed cylinder 1; the oil discharge pipe structure 12 is provided above the diverter plate 61; and the water drain pipe structure 13 is provided below the diverter plate 61;

[0059] The fixed cylinder 1 is rotatably connected to the inflatable cylinder 2; a stirring structure 21 is provided on the outer wall of the inflatable cylinder 2; the stirring structure 21 is tilted; a connecting groove 211 is provided on the stirring structure 21; air holes 212 are evenly spaced on the stirring structure 21; the inflatable cylinder 2 is connected to the air source;

[0060] Water holes 14 are evenly spaced on the bottom surface of the fixed cylinder 1; a No. 1 seal 62 is slidably connected to the lower end of the fixed cylinder 1; the No. 1 seal 62 is connected to the inflatable cylinder 2 via a driving member 63; the driving member 63 is used to change the position of the No. 1 seal 62;

[0061] The separation mechanism 4 is used to separate the particulate impurities in the sewage; the power mechanism 3 is used to drive the inflation cylinder 2 to rotate.

[0062] During operation, the staff opens the valve of the water inlet pipe structure 11 through the controller (valves are provided on both the water inlet pipe structure 11 and the drainage pipe structure 13 to control the on-off of the water inlet pipe structure 11 and the drainage pipe structure 13), closes the valve of the drainage pipe structure 13, and delivers sewage to the fixed cylinder 1 through the water inlet pipe structure 11. At the same time, the air source is activated through the controller to deliver compressed gas to the aeration cylinder 2. The compressed gas moves into the fixed cylinder 1 through the aeration cylinder 2, the connecting groove 211 and the air hole 212, causing a large number of bubbles to appear in the sewage. The bubbles move upward in the sewage, causing the oil in the sewage to quickly gather and condense under the action of the bubbles to form oil floating on the surface of the sewage. The sewage level continues to rise. At the same time, the power mechanism 3 drives the aeration cylinder 2 to rotate forward, driving the stirring structure 21 to rotate forward. When the stirring structure 21 rotates, the sewage rotation is accelerated, causing the sewage and oil to produce centrifugal Force, since the density of oil is less than that of sewage, the centrifugal force of oil is less than that of sewage, so the oil is close to the axis of the fixed cylinder 1. When the sewage liquid level reaches the set value, the centrifugal force of the upper sewage and the surface floating oil disappears, and the upper sewage liquid level is higher than the drainage pipe structure 13. At this time, the valve of the drainage pipe structure 13 is opened by the controller to make the sewage flow out through the drainage pipe structure 13. The drainage volume of the drainage pipe structure 13 per unit time is consistent with the water intake volume of the water inlet pipe structure 11 per unit time. At this time, the sewage discharge volume and the intake volume maintain a dynamic balance. The stirring structure 21 is arranged close to the bottom surface of the fixed cylinder 1. As the height of the fixed cylinder 1 increases, the centrifugal force of the sewage and oil becomes smaller and smaller. Because the centrifugal force of the oil is less than that of the sewage, when the oil rises, an axis is formed in the sewage, which coincides with the axis of the fixed cylinder 1 in the conical area (such as Figure 17 As shown in FIG), when the sewage flows out through the drainage pipe structure 13, the oil will not flow out with the sewage, but will continue to move upwards and eventually gather and condense on the surface of the sewage to form an oil floating area (as shown in FIG). Figure 17 As shown in FIG), when the surface height of the floating oil exceeds the oil hole 611, the floating oil will flow from the oil hole 611 to the diverter plate 61 and be discharged through the oil discharge pipe structure 12, thereby achieving the purpose of removing oil pollution; when the stirring structure 21 rotates in the forward direction, it drives the particulate impurities to move upward, forming a columnar mixing area at the bottom of the fixed cylinder 1 (as shown in FIG). Figure 17As shown in ), the oil on the surface of the particulate impurities fully interacts with the bubbles, so that the oil on the surface of the particulate impurities is separated from the particulate impurities, and finally gathers and condenses on the surface of the sewage to form floating oil; when the opening time of the valve of the drain pipe structure 13 reaches the set value, the valves of the water inlet pipe structure 11 and the drain pipe structure 13 are closed, and the inflation cylinder 2 continues to rotate forward for a period of time, and then the controller stops the gas source. At this time, the oil in the sewage and the oil in the particulate impurities are completely separated from the sewage and gathered on the surface of the sewage to form floating oil, and then the power mechanism 3 drives the inflation cylinder 2 to rotate in the opposite direction. At the initial stage of the reverse rotation of the inflation cylinder 2, the driving member 63 drives the No. 1 seal 62 to move downward, so that the No. 1 seal 62 moves to the lowest position, so that the water hole 14 is opened, and the sewage and particulate impurities in the columnar mixing area flow through the water hole 14 to the separation mechanism 4, and the water hole 1 After the opening time reaches the set value, the power mechanism 3 drives the inflation cylinder 2 to rotate forward. At the initial stage of the forward rotation of the inflation cylinder 2, the driving member 63 drives the No. 1 seal 62 to move upward, so that the No. 1 seal 62 moves to the highest position, and the No. 1 seal 62 blocks the water hole 14 (at this time, the sewage level is still higher than the height of the water inlet pipe structure 11). Then, the controller opens the valve of the water inlet pipe structure 11, allowing the sewage to continue to enter the fixed cylinder 1, and the air source is activated. When the sewage liquid level reaches the set value, the controller opens the valve of the drain pipe structure 13 to continue separating the oil and dirt in the sewage. After the No. 1 seal 62 blocks the water hole 14, the controller activates the separation mechanism 4, which separates the particulate impurities in the sewage. The above operation is repeated to separate the oil and dirt from the sewage.

[0063] When the stirring structure 21 rotates, the oil in the sewage fully reacts with the bubbles, thereby increasing the probability of separating the oil from the sewage and improving the quality of oil separation.

[0064] The separation mechanism 4 includes a connecting cylinder 41, a funnel 42, a filter element 43, a sliding frame 44, a rotating cylinder 45, a connecting shaft 46, a fixing ring 47, a second sealing element 48 and a frame 49;

[0065] The frame 49 is fixedly connected to the fixed cylinder 1 and the connecting cylinder 41; the lower end of the fixed cylinder 1 is fixedly connected to the funnel 42; the upper end of the connecting cylinder 41 is fixedly connected to the filter element 43; the upper end of the connecting cylinder 41 is provided with a water outlet pipe structure 411;

[0066] The frame 49 is slidably connected to the sliding frame 44; a circular plate structure 441 is provided on the upper end of the sliding frame 44; an annular sealing member 442 is fixedly connected to the side wall of the circular plate structure 441;

[0067] The circular plate structure 441 is rotatably connected to the rotating cylinder 45; the rotating cylinder 45 is slidably connected to the connecting shaft 46;

[0068] The upper end of the connecting shaft 46 is fixedly connected to the fixing ring 47; a scraping structure 471 is provided in the circumferential direction of the fixing ring 47; the upper end of the connecting shaft 46 is rotatably connected to the second sealing member 48;

[0069] The separation mechanism 4 also includes a power assembly No. 1 51, a power assembly No. 2 52 and a power assembly No. 3 53; the power assembly No. 1 51 is used to change the relative position between the fixed ring 47 and the circular plate structure 441; the power assembly No. 2 52 is used to drive the sliding frame 44 to move up and down; the power assembly No. 3 53 is used to drive the rotating cylinder 45 to rotate.

[0070] Before the power mechanism 3 drives the inflatable cylinder 2 to rotate in the opposite direction, the controller is used to make the No. 2 power assembly 52 work, and the No. 2 power assembly 52 drives the sliding frame 44 to move upward, so that the circular plate structure 441 abuts against the lower end of the connecting cylinder 41, and the lower opening of the connecting cylinder 41 is blocked, and then the inflatable cylinder 2 is rotated in the opposite direction, so that the sewage enters the funnel 42 through the water hole 14 and enters the connecting cylinder 41 through the lower outlet of the funnel 42. After the No. 1 seal 62 blocks the water hole 14, the controller is used to make the No. 1 power assembly 51 work, so that the connecting shaft 46 moves upward, driving the fixing ring 47 and the No. 2 seal 48 to move upward, so that the distance between the fixing ring 47 and the circular plate structure 441 reaches the maximum. At this time, the scraping structure 471 abuts against the lower surface of the filter element 43, and the No. 2 seal 48 abuts against the lower opening of the funnel 42, and the lower opening of the funnel 42 is blocked. The force assembly 52 continues to drive the sliding frame 44 to move upward, driving the circular plate structure 441 to move upward, increasing the sewage pressure, causing the sewage to move upward through the filter element 43 and be discharged through the outlet pipe structure 411, while the particulate impurities are blocked by the filter element 43 in the connecting cylinder 41, thereby achieving separation of the particulate impurities in the sewage; when separating the particulate impurities, the controller activates the No. 3 power assembly 53, which drives the rotating cylinder 45 to rotate, drives the connecting shaft 46 to rotate, drives the fixing ring 47 to rotate, and drives the scraping structure 471 to rotate. The scraping structure 471 scrapes off the particulate impurities on the surface of the filter element 43 to prevent the particulate impurities from obstructing the flow of sewage through the filter element 43 (when the filter element 43 is arranged below the connecting cylinder 41, the particulate impurities will accumulate on the upper surface of the filter element 43, and even if the scraping structure 471 scrapes off the particulate impurities on the surface of the filter element 43, it will cause blockage);

[0071] After the sewage in the connecting cylinder 41 is completely discharged, the controller is used to activate the No. 1 power component 51, which causes the fixing ring 47 to contact the surface of the circular plate structure 441, and the scraping structure 471 to contact the surface of the circular plate structure 441. Then the No. 2 power component 52 drives the sliding frame 44 to move downward to the lowest position, and the No. 3 power component 53 drives the connecting shaft 46 to rotate, driving the scraping structure 471 to rotate. The scraping structure 471 drives the particulate impurities on the circular plate structure 441 to rotate, causing the particulate impurities to generate centrifugal force, causing the particulate impurities to leave the circular plate structure 441, and cleaning the particulate impurities on the circular plate structure 441.

[0072] The first power assembly 51 includes a rotating member 511, a first elastic member 512, a limiting member 513, a first threaded shaft 514 and a fourth motor 515;

[0073] The sliding frame 44 is rotatably connected to the rotating member 511; an annular limiting groove 461 is provided on the outer wall of the connecting shaft 46; the lower end of the connecting shaft 46 is slidably connected to the rotating member 511; the rotating member 511 rotates synchronously with the connecting shaft 46;

[0075] The upper end of the rotating member 511 is slidably connected to the limit member 513; a limit structure 5131 is provided at one end of the limit member 513; the other end of the limit member 513 is threadedly connected to the No. 1 threaded shaft 514; the No. 1 threaded shaft 514 is rotatably connected to the rotating member 511; the No. 4 motor 515 is fixedly connected to the rotating member 511; the No. 1 threaded shaft 514 and the rotating shaft of the No. 4 motor 515 rotate synchronously.

[0076] When it is necessary to make the fixing ring 47 contact the surface of the circular plate structure 441, the controller is used to operate the No. 4 motor 515, and the No. 4 motor 515 drives the No. 1 threaded shaft 514 to rotate, and drives the limiting member 513 to move, so that the limiting structure 5131 contacts the annular limiting groove 461, and the relative height of the connecting shaft 46 and the sliding frame 44 remains unchanged, so that the fixing ring 47 contacts the surface of the circular plate structure 441; after the No. 1 sealing member 62 blocks the water hole 14, the No. 4 motor 515 drives the No. 1 threaded shaft 514 to rotate in the opposite direction, and drives the limiting member 513 to move in the opposite direction, so that the limiting structure 5131 disengages from the annular limiting groove 461, and under the action of the elastic force of the No. 1 elastic member 512, the connecting shaft 46 moves upward, so that the distance between the fixing ring 47 and the circular plate structure 441 reaches the maximum.

[0077] An annular slope structure 463 is provided on the lower side wall of the annular limiting groove 461 .

[0078] When there are a lot of particulate impurities, after the sewage in the connecting cylinder 41 is completely discharged, there is a distance between the fixed ring 47 and the circular plate structure 441. When the limiting member 513 moves, the limiting structure 5131 abuts against the annular ramp structure 463. The limiting structure 5131 exerts a force on the annular ramp structure 463, causing the annular ramp structure 463 to move downward, causing the connecting shaft 46 to move downward, causing the limiting structure 5131 to finally abut against the annular limiting groove 461, causing the scraping structure 471 to abut against the circular plate structure 441, thereby improving the adaptability of the separation mechanism 4.

[0079] A first rotation groove 15 is provided on the bottom surface of the fixed cylinder 1; a shaft-like structure 22 is provided at the lower end of the inflatable cylinder 2; the shaft-like structure 22 passes through the first rotation groove 15; the outer wall of the shaft-like structure 22 is sealedly connected to the inner wall of the first rotation groove 15;

[0080] The shaft structure 22 is provided with a driving groove 221; the driving groove 221 includes a spiral portion 2211, an upper annular portion 2212 and a lower annular portion 2213; the upper end of the spiral portion 2211 is connected to the upper annular portion 2212; the lower end of the spiral portion 2211 is connected to the lower annular portion 2213;

[0081] The No. 1 sealing member 62 includes a No. 1 annular structure 621 and a No. 1 sealing structure 622; the No. 1 sealing structure 622 is evenly spaced on the No. 1 annular structure 621; the driving member 63 is connected to the inner wall of the No. 1 annular structure 621; the shaft-like structure 22 is in contact with the inner hole of the No. 1 annular structure 621; and the driving member 63 is in contact with the driving groove 221.

[0082] When the inflator 2 starts to rotate in the opposite direction, the driving member 63 comes into contact with the upper annular portion 2212. When the connection between the spiral portion 2211 and the upper annular portion 2212 rotates to the driving member 63 position, the driving member 63 enters the spiral portion 2211. The inner wall of the spiral portion 2211 exerts a force on the driving member 63, causing the driving member 63 to move downward, driving the No. 1 annular structure 621 to move downward. When the connection between the spiral portion 2211 and the lower annular portion 2213 rotates to the driving member 63 position, the driving member 63 enters the lower annular portion 2213, keeping the height of the driving member 63 stationary. At this time, the No. 1 annular structure 621 moves to the lowest position, the No. 1 sealing structure 62 moves to the lowest position, and the No. 1 sealing structure 622 disengages from the water hole 14, opening the water hole 14 (the inflator 2 continues to rotate in the opposite direction, the height of the driving member 63 remains stationary, and the No. 1 sealing structure 622 remains stationary).

[0083] When the connecting portion between the spiral portion 2211 and the lower ring portion 2213 rotates to the position of the driving member 63, the driving member 63 enters the spiral portion 2211, and the inner wall of the spiral portion 2211 exerts a force on the driving member 63, causing the driving member 63 to move upward, thereby driving the No. 1 ring structure 621 to move upward. When the connecting portion between the spiral portion 2211 and the upper ring portion 2212 rotates to the position of the driving member 63, the driving member 63 enters the upper ring portion 2212, so that the height of the driving member 63 remains unchanged. At this time, the No. 1 sealing structure 62 moves to the highest position, and the No. 1 sealing structure 622 contacts the water hole 14 to block the water hole 14 (the inflatable cylinder 2 continues to rotate forward, the height of the driving member 63 remains unchanged, and the No. 1 sealing structure 622 remains unchanged);

[0084] When the No. 1 seal 62 moves to the highest position, the upper surface of the No. 1 sealing structure 622 is coplanar with the bottom surface of the fixed cylinder 1, preventing the accumulation of granular impurities with oil stains in the water hole 14, and preventing the granular impurities with oil stains in the water hole 14 from directly entering the connecting cylinder 41.

[0086] When the connection between the spiral portion 2211 and the upper annular portion 2212 rotates to the position of the driving member 63, the No. 2 elastic member 623 generates an elastic force on the No. 1 annular structure 621, causing the No. 1 annular structure 621 to generate a downward force, causing the driving member 63 to generate a downward force, so that the driving member 63 can reliably enter the spiral portion 2211. When the connection between the spiral portion 2211 and the lower annular portion 2213 rotates to the position of the driving member 63, the No. 2 elastic member 623 generates a pulling force on the No. 1 annular structure 621, causing the No. 1 annular structure 621 to generate an upward force, causing the driving member 63 to generate an upward force, so that the driving member 63 can reliably enter the spiral portion 2211, thereby improving the reliability of the driving member 63.

[0088] The No. 3 seal 4412 seals the gap between the outer wall of the rotating cylinder 45 and the inner wall of the No. 3 rotating groove 4411 to prevent sewage from leaking through the gap between the outer wall of the rotating cylinder 45 and the inner wall of the No. 3 rotating groove 4411; the No. 4 seal 451 seals the gap between the outer wall of the connecting shaft 46 and the inner wall of the rotating cylinder 45 to prevent sewage from leaking through the gap between the outer wall of the connecting shaft 46 and the inner wall of the rotating cylinder 45.
