The hose 55 is communicated with the collector 54, passes through the first box body 1, and extends to the outside of the second box body 51.

[0031] In this embodiment, the chemical machinery oil recovery equipment 100 also includes a controller, electrically connected to the first drive member 53, for controlling its movement. The controller is a master device that controls the motor's starting, speed regulation, braking, and reversing by changing the wiring and resistance values ​​of the main or control circuits in a predetermined sequence. It comprises a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It serves as the "decision-making mechanism" for issuing commands and may be model AMF25. The box body is a cavity structure, which is used to store oil-water mixture for oil-water separation. The first box body 1 has a liquid inlet 11, a liquid outlet 12 and an observation window 13. The liquid inlet 11 is located on one side of the second cavity 15. The liquid pump 3 draws the oil-water mixture into the second cavity 15 through the liquid inlet 11. The liquid outlet 12 is located at the bottom of the first box body 1. After the oil-water separation operation is completed, water is discharged from the liquid outlet 12. The observation window 13 is a transparent glass window, covering and extending the first cavity 14 and the second cavity 15. The oil-water separation status in the first cavity 14 and the second cavity 15 can be viewed through the observation window 13. The fixing member 41 and the isolating member 2 are fixed in the first box body 1 and are located on the same horizontal line, and are used to support the first filter screen 42. The first filter screen 42 divides the cavity of the first box body 1 into a first cavity 14 and a second cavity 15 opposite to each other. The first cavity 14 is used for oil-water separation, and the second cavity 15 is used to isolate a large amount of impurities. The isolating member 2 is used to support and connect the second filter screen 43. The fixing member 41 is used to connect the second filter screen 43. The elastic member 44 is a spring. The two movable members 45 move relative to each other with the expansion and contraction of the corresponding springs to seal the through groove 411. The connecting member 46 is used to connect the second filter screen 43 and the fixing member 41. The second box body 51 is located on one side of the first box body 1 and is used to place various driving components. The first driving component 53 is a cylinder, which is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The model can be GJ20. The cylinder drives the sliding component 52 to move up and down. The collector 54 is used to collect oil floating on the water. The hose 55 is used to transport the collected oil to the collection box outside the second box body 51. The hose 55 can move with the movement of the sliding component 52.Specifically, the liquid pump 3 pumps the oil-water mixture into the second cavity 15 through the liquid inlet 11. Since the density of oil is less than that of water, the oil will float on the surface of the water and slowly float in the first cavity 14. At the same time, a large amount of impurities also enter the second cavity 15 with the oil-liquid mixture. The heavy ones settle at the bottom of the first box 1, and the light ones float under the first filter 42, thereby achieving separation of the oil and a large amount of impurities. The position of the oil is observed through the observation window 13, and the first driving member 53 drives the sliding member 52 to the specified position so that the collector 54 is located in the oil layer. The oil enters the hose 55 through the collector 54 and is then transported to the collection box outside the second box 51 for storage and processing. At this time, the connecting member 46 is clamped in the two moving members 45 and is located in the through groove 411; after a period of time After the oil and water are separated, it is checked through the observation window 13 that when a large amount of impurities gather under the first filter 42 and block it, affecting the oil-liquid mixture from entering the first cavity 14, the first driving member 53 drives the sliding member 52 to slide downward, so that the two first protrusions 521 respectively abut against the two moving members 45, the two elastic members 44 are compressed, and the connecting member 46 falls off without clamping pressure. Affected by the weight of the second filter 43, the second filter 43 rotates downward, and the length of the second filter 43 is equal to the height of the second cavity 15, so that a large amount of impurities gathered under the first filter 42 are all isolated on one side of the first box 1. At this time, the oil-water mixture can move upward in large quantities, and the first filter 42 can also filter micro impurities, continue to separate the oil and water, reduce the entry of impurities, and improve the oil-water separation effect.

[0032] The chemical machinery oil collecting equipment 100 is characterized in that the first filter screen 42 is fixedly connected above the isolation piece 2 and the fixing piece 41, and divides the first box 1 into the first cavity 14 and the second cavity 15 opposite to each other; the second filter screen 43 is rotatably connected with the isolation piece 2, and detachably connected with the fixing piece 41, and located in the second cavity 15; the fixing piece 41 has a through slot 411 and two sliding grooves 412, the two sliding grooves 412 are located on both sides of the through slot 411, each elastic piece 44 is located in each sliding groove 412, each moving piece 45 is fixedly connected with the elastic piece 44, the connecting piece 46 is fixedly connected with the second filter screen 43, and abuts between the two moving pieces 45; the sliding piece 52 is slidably connected in the first cavity 14 and located above the fixing piece 41, the output end of the first driving piece 53 is in transmission connection with the sliding piece 52 and located in the second box 51, the sliding piece 52 has two first protrusions 521, the two first protrusions 521 abut the two moving pieces 45 respectively, the collector 54 is fixedly connected with the sliding piece 52 and located in the first cavity 14, and the hose 55 is in communication with the collector 54. The oil-water mixture enters the second cavity 15, the first filter screen 42 blocks a large amount of impurities, the two first protrusions 521 move downward to abut the two moving pieces 45, so that the connecting piece 46 is separated from the fixing piece 41, the first filter screen 42 separates a large amount of impurities on one side of the second cavity 15, the first filter screen 42 continues to filter, and the collector 54 collects oil, so that a large amount of impurities is reduced and the oil-water separation effect is improved.

[0033] Further, the filter device 4 further comprises a rotating assembly 47, the rotating assembly 47 comprises a second driving piece 471, a rotating shaft 472 and a plurality of blades 473, the second driving piece 471 is located in the isolation piece 2, the rotating shaft 472 is in transmission connection with the output end of the second driving piece 471 and located in the second cavity 15, and the plurality of blades 473 are integrally formed with the rotating shaft 472 and uniformly distributed in the circumferential direction of the rotating shaft 472.

[0034] In this embodiment, the second driving member 471 is a motor, which refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. The model can be 1TL0001. Its main function is to generate driving torque to drive the rotating shaft 472 to rotate. The isolating member 2 is used to accommodate the second driving member 471. The multiple blades 473 and the rotating shaft 472 are integrally formed with the structure, and the second driving member 471 is electrically connected to the controller. The controller controls the rotation of the second driving member 471, and then drives the multiple blades 473 to rotate, thereby stirring the oil-water mixture in the second cavity 15, so that the oil attached to the impurities falls off and floats on the water surface for oil collection.

[0035] Furthermore, the filtering device 4 also includes a reset assembly 48, which includes a support member 481, a third driving member 482, a pulley 483 and a connecting rope 484. The support member 481 is fixedly connected to the sliding member 52 and is located on the side of the sliding member 52 away from the fixed member 41. The third driving member 482 is fixedly connected to the support member 481, and the pulley 483 is transmission-connected to the output end of the third driving member 482. One end of the connecting rope 484 is fixedly connected to the connecting member 46, and the other end is sleeved on the pulley 483.

[0036] In this embodiment, the support member 481 is used to support the third driving member 482 and the pulley 483. During the movement of the sliding member 52, the third driving member 482 and the pulley 483 are always located above the oil liquid level; the third driving member 482 is a motor, and the third driving member 482 is electrically connected to the controller. When the oil-water separation is completed, the water in the first box 1 is discharged through the liquid outlet 12 to clean the impurities. When the next oil-water separation is performed, the controller controls the third driving member 482 to rotate, thereby driving the pulley 483 to rotate, so that the connecting rope 484 passing through the through groove 411 is wound around the pulley 483, thereby shortening the connecting rope 484, thereby driving the connecting member 46 and the second filter 43 to move closer to the fixed member 41, and the two movable members 45 move to abut against the connecting member 46, so that the second filter 43 is set between the first cavity 14 and the second cavity 15, which is convenient for impurity separation and oil-water separation, and is efficient and intelligent.

[0037] Furthermore, the filtering device 4 further includes a third filter screen 49 , which is fixedly connected to the first housing 1 and is located in the second cavity 15 and below the rotating shaft 472 .

[0038] In this embodiment, the extension direction of the third filter 49 is perpendicular to the extension direction of the second filter 43, and is used for forming an enclosed space among the second filter 43, the third filter 49 and the side wall of the first box body 1 when the second filter 43 rotates close to the side wall of the first box body 1, and the impurities will be located in the enclosed space due to the movement and floating force of the first filter 42. When the oil-water separation is completed and the water in the first box body 1 is drained, the impurities will be isolated on the third filter 49 for easy cleaning, and the oil on the impurities can be drained for post-processing to prevent the oil from polluting the environment.

[0039] Furthermore, the second filter screen 43 has a second protrusion 431 , and the second protrusion 431 is located on a side of the second filter screen 43 away from the connecting member 46 .

[0040] In this embodiment, the second protrusion 431 abuts against the side wall of the first box body 1 to prevent the second filter screen 43 from directly contacting the side wall of the first box body 1 after rotation to form a triangular area, which makes it easy for impurities to leak from the bottom and affect oil-water separation.

[0041] Furthermore, the moving member 45 has an inclined surface 451 , and the inclined surface 451 is located on a side facing the first protrusion 521 .

[0042] In this embodiment, the setting of the inclined surface 451 makes it easier for the first protrusion 521 to press against the movable member 45 as the sliding member 52 moves, thereby achieving the detachment of the second filter 43 from the fixing member 41, thereby isolating impurities and improving the reaction speed.

[0043] Furthermore, the collector 54 also includes a first drainage tube 541, a second drainage tube 542 and a drainage basin 543. The first drainage tube 541 is fixedly connected to the sliding member 52 and is connected to the hose 55. The second drainage tube 542 is connected to the first drainage tube 541.

[0044] In this embodiment, the cross-sectional area of ​​the drainage basin 543 is trapezoidal, and the top edge is located on the side close to the second drainage tube 542, so as to facilitate a large amount of oil to enter the drainage basin 543. The first drainage tube 541 and the second drainage tube 542 have an angle, which is 120° to 150°, so as to facilitate the oil to be drained into the hose 55 under the action of gravity.

[0045] Furthermore, the collecting device 5 further includes a distance sensor 56 , and the distance sensor 56 is located in the drainage basin 543 .

The controller receives the distance signal of the distance sensor 56, controls the first driving member 53 to drive the sliding member 52 to move up and down, and adjusts the position to collect oil, that is, the upper surface of the drainage basin 543 is always located in the oil layer; when the oil layer is insufficient, the sliding member 52 is driven to move upward so that the drainage basin 543 is located above the water surface to prevent water from entering the drainage basin 543 and mixing with the oil, affecting the separation effect. The model of the distance sensor 56 can be KTC-225MM.

[0047] Furthermore, the drainage basin 543 has a drainage groove 5431 , and the drainage groove 5431 is located on a side away from the second drainage pipe 542 .

[0048] In this embodiment, the drainage groove 5431 is used to drain the oil, and fine impurities may also adhere to the drainage basin 543 and be cleaned later.

[0049] Furthermore, the chemical machinery oil recovery equipment 100 further includes a nozzle 6 , which is fixedly connected to the first box 1 and is located in the first cavity 14 .
