Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, in particular to wastewater oil-water separation equipment based on rubber recovery. Background Art

[0002] Rubber wastewater typically contains high concentrations of organic matter, ammonia nitrogen, oil, and suspended solids. Direct discharge can cause serious environmental pollution. The basic principle of mechanical treatment of rubber wastewater is to use physical methods such as gravity sedimentation, centrifugal separation, and filtration to remove suspended solids and oily substances in the wastewater, thereby achieving oil-water separation. Chinese patent application number 202411679266.3 discloses "an oil-water separation device for waste rubber recycling wastewater, belonging to the field of wastewater treatment, to address the problem of poor oil-water separation quality of existing oil-water separation equipment. The present invention comprises an oil removal plate, a rubber concave gasket, a top plate, a magnetic bevel block, and an oil receiving plate. During operation, wastewater is poured from the feed pipe and flows along the guide plate to the oil removal plate. The oil removal plate is an oleophilic and hydrophobic polypropylene plate. When the wastewater passes through the oil removal plate, the oil adheres to its surface, and the rubber concave gasket also adheres to some of the oil, while the water flows along the oil removal plate to the outer guide plate, thereby achieving the purpose of preliminary oil-water separation and greatly improving work efficiency." This technical solution only solves the problem that oil will slowly adhere to the filter net, which will cause the filter net to be unable to continue to separate oil and water in the wastewater over time. However, the comparative document uses oleophilic and hydrophobic polypropylene plates for oil and water separation. For flowing oily wastewater, the oil removal effect is poor, and the oil scraping method is not convenient for continuous oil removal. In rubber production, when a filter layer is used to treat rubber wastewater, since oil substances easily adhere to the surface of the filter layer, the water permeability of the filter layer is reduced, and the filter layer needs to be replaced frequently, which is not conducive to efficient treatment of wastewater.

[0023] In this embodiment, Figure 3 and Figure 4As shown, the oil suction mechanism 5 includes an oil suction box 502, an oil suction pipe 503, an oil suction head 504 and a hard pipe 505.

[0025] In this embodiment, Figure 5 and Figure 6As shown, the oil suction mechanism 5 includes a connecting shaft 510, a first gear 511 and a transmission belt 512.

The first gear 511 is movably connected to the limit cover 507 through meshing. When the limiting cover 507 moves toward the wastewater tank 1, the first gear 511 is driven to rotate, thereby driving the connecting shaft 510 to rotate. When the connecting shaft 510 rotates, the transmission belt 512 drives a group of connecting shafts 510 located at the lower layer to rotate, so that the first gear 511 thereon rotates accordingly, thereby driving the limiting cover 507 located at the lower layer to move toward the water inlet joint 404.

[0026] In this embodiment, Figure 3 As shown, the oil suction mechanism 5 includes a connecting pipe 513, a hose 514 and an oil outlet pipe 515.

[0027] In other aspects, this embodiment also provides a synchronization mechanism 6 for cyclically controlling the operation of the first filter chamber and the second filter chamber and performing the oil removal operation synchronously, such as Figure 6 and 7 As shown, the synchronization mechanism 6 includes two groups of support slide bars 601 , which are fixedly mounted at the top and middle of the inner portion of the support frame 501 .

[0028] In this embodiment, Figure 7 As shown, the synchronization mechanism 6 includes a slider 602, a spring 603 and a second connecting rod 604. The slider 602 is movably connected to the support slide 601, and the spring 603 is movably connected to the support slide 601. There are two sets of second connecting rods 604, and the top end is movably connected to the top end of the side of the rotating plate 408 away from the oil-water separation box 401, and the bottom end is movably connected to the slider 602. The second connecting rod 604 is connected via the slider 602 so that the bottom end of the second connecting rod 604 moves along the supporting slide bar 601 .

[0029] In this embodiment, Figure 6 As shown, the synchronization mechanism 6 includes a rotating shaft 605, a second gear 606 and a translation frame 607. There are two rotating shafts 605, which are movably mounted on the bottom ends of the two connecting boxes 407. The bottom ends of the two rotating plates 408 are fixedly sleeved in the middle of the two rotating shafts 605. There are two groups of second gears 606, which are fixedly sleeved on both ends of the two rotating shafts 605. The translation frame 607 is fixedly mounted on the end of each group of limit covers 507 away from the oil-water separation box 401. The translation frame 607 is movably connected to the bottom end of the second gear 606 through meshing. The rotating plate 408 located below is driven to rotate from a vertical state through the translation frame 607. When the rotating plate 408 rotates, the translation rod 406 is driven to move through the first connecting rod 409, so that the plug 405 closes the water inlet joint 404 located below, so that the oily wastewater in the wastewater pipe 3 no longer enters the second filter chamber. When the rotating plate 408 rotates, the slider 602 is driven to move through the second connecting rod 604, and the spring 603 is compressed.

[0030] Working principle: When the present invention is in use, the rubber wastewater is poured into the wastewater tank 1, the rubber particles in the rubber wastewater are isolated through the isolation tank 2, and then the oily wastewater is introduced into the water inlet joint 404 through the wastewater pipe 3, and the electric push rod 508 is started. The electric push rod 508 drives the connecting frame 509 to move away from the oil-water separation box 401, and the two hard pipes 505 inserted in the first filter chamber are driven to move at the same time through the connecting frame 509, and the hard pipes 505 drive the oil suction box 502 to move toward the wastewater tank 1, so that the oil suction box 502 moves to the end of the first filter chamber close to the wastewater tank 1, so that the oily wastewater can be filtered in the first filter chamber. The second gear 606 is driven to rotate by the translation frame 607, so that the rotating shaft 605 follows the second gear 606 to rotate, and the rotating plate 408 is driven to rotate by the rotating shaft 605. When the translation frame 607 leaves the second gear 606, the rotating plate 408 rotates to a vertical state, and the elastic force of the spring 603 keeps the rotating plate 408 in a vertical state. When the rotating plate 408 rotates to a vertical state, the translation rod 406 is driven to move away from the rotating plate 408 by the first connecting rod 409, and then the translation rod 406 is driven to rotate to a vertical state. 406 drives the plug 405 to move away from the oil-water separation box 401, so that the water inlet joint 404 is connected to the oil-water separation box 401, so that the oily wastewater in the wastewater pipe 3 can enter the first filter chamber to filter the oily wastewater. When the upper limit cover 507 moves toward the direction close to the wastewater tank 1, it drives the first gear 511 to rotate and drives the connecting shaft 510 to rotate. When the connecting shaft 510 rotates, the transmission belt 512 drives a group of connecting shafts 510 on the lower layer to rotate, so that the first gear 511 on it rotates accordingly, thereby driving the lower limit cover 507 to move toward the water inlet joint 404. In this process, , the hard tube 505 is driven to move simultaneously by the limit cover 507, so that the oil suction box 502, the oil suction pipe 503 and the oil suction head 504 connected thereto are moved simultaneously. When it moves to one end close to the water inlet joint 404, the translation frame 607 drives the rotating plate 408 located below to rotate from a vertical state. When the rotating plate 408 rotates, the translation rod 406 is driven to move by the first connecting rod 409, so that the plug 405 closes the water inlet joint 404 located below, so that the oily wastewater in the wastewater pipe 3 no longer enters the second filter chamber. When the rotating plate 408 rotates, the slider 602 is driven to move by the second connecting rod 604, and the spring 603 is compressed; After the hard tube 505 drives the second sealing sleeve 506 to expand, the volume of the second filter chamber is reduced to speed up the filtration. The oil suction box 502 is moved and the solenoid valves in the two upper hard tubes 505 are closed at the same time, so that the solenoid valves in the two lower hard tubes 505 are opened. Then the oil pump is started to absorb the oil layer attached to the bottom end of the first filter layer 402 and the top end of the second filter layer 403 through the oil suction head 504, so that the first filter layer 402 and the second filter layer 403 can maintain their filtering capacity and avoid being blocked by the isolated oil. The output rod is quickly retracted by the electric push rod 508, so that the connecting frame 509 quickly drives the limit cover 507 to move, so that the adsorption and oil removal process in the second filter chamber is completed quickly, and the water inlet joint 404 connected to the first filter chamber is quickly closed to prevent a large amount of oily wastewater from entering the second filter chamber. Similarly, the oil removal process in the first filter chamber is the same as that in the second filter chamber. During normal use of the device, the second filter chamber is closed so that the oily wastewater first passes through the first filter chamber for oil-water separation and then enters the second filter chamber for oil-water separation to improve the separation effect. During long-term use, the oil layer isolated between the first filter layer 402 and the second filter layer 403 is regularly deoiled to maintain the oil-water separation ability of the first filter layer 402 and the second filter layer 403.
