The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1, see Figure 1-Figure 5The present embodiment provides a chemical waste oil extraction device for refining chemical wastewater, including a sewage bucket 1, an L-shaped bracket plate 2 is fixedly connected to the top of the sewage bucket 1, and a water inlet pipe is installed on the top of the sewage bucket 1 to allow wastewater that needs to be extracted with waste oil to enter the sewage bucket 1. The function of the L-shaped bracket plate 2 is to support the use of the motor 8, thereby facilitating the use of the motor 8. The inside of the L-shaped bracket plate 2 is fixedly connected to the motor 8, and the output shaft of the motor 8 is fixedly connected to the stirring rod 3. The outside of the stirring rod 3 is equipped with a stirring blade 4. The top of the sewage bucket 1 is fixedly connected to the hydraulic cylinder 502, and one end of the hydraulic cylinder 502 is slidably connected to two sets of force rods through a piston. 503. When the force-bearing rod 503 is squeezed upward by the oil dipping rod 512, the internal liquid pressure of the hydraulic cylinder 502 increases, so that the rack rod 504 can be pushed out. The other end of the hydraulic cylinder 502 is slidably connected to two sets of rack rods 504 through pistons. Two sets of oil scraper boxes 501 are slidably connected on both sides of the top of the sewage bucket 1. The sides of the two sets of oil scraper boxes 501 on each side are fixedly connected with sliding blocks 507. The two sets of sliding blocks 507 are internally threaded with bidirectional screw rods 505. The two sets of sliding blocks 507 are internally threaded with bidirectional screw rods 505. Therefore, when the bidirectional screw rods 505 rotate, the two sets of sliding blocks 507 can be made to move. The movable blocks 507 move in the direction of moving away from or approaching each other. The outer sides of the two sets of bidirectional screw rods 505 are fixedly connected to gears 1 506. The tops of the two sets of rack rods 504 are fixedly connected to rectangular blocks 508. Springs 1 509 are elastically connected between the two sets of rectangular blocks 508 and the hydraulic cylinder 502. When the two sets of rack rods 504 are pushed out, the two sets of springs 1 509 can be elastically stretched. When the force squeezing the two sets of force rods 503 disappears, the springs 1 509 can drive the two sets of rack rods 504 to automatically reset under the action of their own rebound force. The interior of the sewage bucket 1 is fixedly connected to a support plate 511. The support plate 511 is internally slidably connected to an oil dipping rod 512. The surface of the support plate 511 is provided with multiple groups of holes so that there will be no obstruction when waste water needs to be extracted from waste oil and enters the sewage bucket 1. The top of the stirring blade 4 is fixedly connected to an extrusion rod 513. The top of the extrusion rod 513 is a convex shape. The interior of the sewage bucket 1 is equipped with a stirring component 6 for preventing oil from solidifying. The interior of the sewage bucket 1 is equipped with a scraping component 7 for cleaning the inner wall of the sewage bucket 1. There are two groups of oil dipping rods 512. The two groups of rack rods 504 are respectively engaged with the two groups of gears 506. The two groups of force rods 503 are respectively located on the movement trajectories of the two groups of oil dipping rods 512.

[0025] When using, people first need to move the device to a position suitable for the use of the device, first, put the sewage that needs to be extracted from waste oil into the sewage bucket 1, and then put the flocculant into the sewage bucket 1. At this time, start the switch of the motor 8, so that the output shaft of the motor 8 can drive the stirring rod 3 to rotate, and then the stirring rod 3 can drive multiple groups of stirring blades 4 to rotate inside the sewage bucket 1, so that the flocculant can fully mix and react with the sewage, and then the oil and water can be quickly separated, and when the stirring rod 3 drives the multiple groups of stirring blades During the rotation of the blade 4, the top of a stirring blade 4 can drive the squeezing rod 513 during the movement, squeezing the oil dipping rod 512, thereby pushing the oil dipping rod 512 upward, so that the oil dipping rod 512 is pushed out above the top of the sewage bucket 1. At this time, when the oil dipping rod 512 moves upward, it can squeeze the force-bearing rod 503, so that the force-bearing rod 503 is subjected to the squeezing force. At this time, the internal liquid pressure of the hydraulic cylinder 502 increases, thereby pushing out the rack rod 504. When the rack rod 504 is pushed out, it can act on the gear 1 50 6. Since the rack rod 504 and the gear 1 506 are in meshing state, when the rack rod 504 is pushed out, the gear 1 506 can be rotated. When the gear 1 506 is rotated, the bidirectional screw rod 505 can be driven to rotate synchronously. When the bidirectional screw rod 505 is rotated, the two sets of oil scraping boxes 501 outside the bidirectional screw rod 505 can be moved closer to each other. At this time, when the squeezing rod 513 no longer squeezes the oil dipping rod 512, the oil dipping rod 512 slides downward under its own gravity, and at the same time, the two sets of oil scraping boxes 501 move towards the oil dipping rod 512. 12 is approached, so that the oil sucked on the outside of the oil dipping rod 512 can be scraped, so that the oil dipped by the oil dipping rod 512 enters the oil scraper box 501 for collection. At the same time, when the force squeezing the force-bearing rod 503 disappears, the spring 1 509 is stretched and, under the action of its own rebound force, drives the rack rod 504 to reset, and at the same time, causes the gear 1 506 to rotate in the opposite direction, driving the two sets of oil scraper boxes 501 to slide in the direction away from each other, and so on. The reciprocating motion enables the oil dipping rod 512 to dip oil repeatedly.

[0026] Example 2, see Figures 1-8On the basis of Example 1, the stirring assembly 6 in this application includes a medicine box 601, the top of the medicine box 601 is connected to a water pipe 602 through a water pump, and the end of the water pipe 602 away from the water pump is connected to a water storage tray 603, which is used to store medicine for spraying four groups of water spray heads 604. The bottom end of the water storage tray 603 is equipped with a water spray head 604, and the bottom end of the support plate 511 is fixedly connected to a special-shaped rack 605. The bottom end of the water storage tray 603 is fixedly connected to two The two groups of rectangular plates 606 are used to support the rotational movement of the two groups of rotating rods 609 respectively. The bottom ends of the two groups of rectangular plates 606 are rotatably connected to the rotating rods 609. The end of the special-shaped rack 605 is an arc-shaped structure. The outer sides of the two groups of rotating rods 609 are fixedly connected with gear 2 608. The ends of the two groups of rotating rods 609 are fixedly connected with stirring plates 607. There are four groups of water spray heads 604 in total. Gear 2 608 is engaged with the special-shaped rack 605.

[0027] During use, on the basis of Example 1, at the same time, a medicine for preventing the oil from solidifying is placed inside the medicine box 601, and the cooperation between the water pump and the water pipe 602 allows the medicine to enter the water storage tray 603. At the same time, the water storage tray 603 is fixed to the stirring rod 3, so when the stirring rod 3 rotates, the water storage tray 603 can also rotate, and at the same time, it can drive the four groups of water spray heads 604 to rotate synchronously, so that the medicine can be sprayed into the interior of the sewage bucket 1 through the four groups of water spray heads 604. At the same time, when the water storage tray 603 rotates, it can drive the two groups of stirring plates 607 to rotate synchronously. When the two groups of stirring plates 607 rotate, the two groups of gears 2 608 can be engaged with the special-shaped rack 605 respectively, so that the stirring plates 607 are flipped 180 degrees, so that the inside of the sewage bucket 1 can be stirred, so that the medicine is fully mixed with the extracted oil, thereby preventing the extracted oil from solidifying and being difficult to extract.

[0028] Example 3, see Figures 1-10On the basis of Example 1, the scraping assembly 7 in this application includes a support rod 702. The function of the support rod 702 is to link the movement of the scraper 704 with the movement of the stirring rod 3, so that when the stirring rod 3 rotates, it can drive the scraper 704 to follow and rotate synchronously. One end of the support rod 702 is fixedly connected to the outside of the stirring rod 3, and the other end of the support rod 702 is fixedly connected to the scraper 704. The scraper 704 is attached to the inner wall of the sewage bucket 1 for scraping. A squeezing ball 705 is fixedly connected to the top, and multiple groups of convex grooves 701 are provided at the bottom of the support plate 511. A rectangular groove 707 is provided on the side of the scraper 704. A spring 2 706 is elastically connected inside the rectangular groove 707. The squeezing ball 705 has the same size as the multiple groups of convex grooves 701. The squeezing ball 705 has the same size as the multiple groups of convex grooves 701. Therefore, when the scraper 704 drives the squeezing ball 705 to rotate, the scraper 704 can move back and forth up and down.

[0029] During use, based on Example 1, when the stirring rod 3 rotates, the support rod 702 can make the scraper 704 also follow the synchronous rotation, so that the scraper 704 can perform a scraping motion along the inner wall of the sewage bucket 1. At the same time, since the squeezing ball 705 at the top of the scraper 704 can interact with the convex groove 701, the scraper 704 can perform an up and down scraping motion under the action of multiple groups of convex grooves 701 during the rotation. At the same time, when the squeezing ball 705 is located inside the convex groove 701, the spring 2 706 is in a normal state. When the squeezing ball 705 moves to a state where it is no longer located inside the convex groove 701, the spring 2 706 is elastically compressed.
