Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an intelligent temperature-controlled oil-water separation and lifting integrated device. Background Technology

[0002] Oily wastewater treatment is a process that removes oil and other pollutants from industrial or domestic wastewater containing mineral oil, animal and vegetable oils, etc., using physical, chemical, and biological methods to ensure the water quality meets discharge standards or reuse requirements. Oil-water separation is the core pre-treatment step in oily wastewater treatment. This process prevents grease from solidifying and clogging pipes, causing corrosion, significantly reducing dredging and maintenance costs, and preventing oil film from covering the water surface after discharge, which could lead to oxygen depletion and ecological damage.

[0003] In existing technologies, intelligent temperature-controlled oil-water separation and lifting integrated equipment utilizes the density difference between oil and water, causing the oil to naturally float and gather above the water, forming an oil-water stratification. The oil is then discharged through pipes. However, due to the adhesive and viscous nature of grease, when the oil gathers, it adheres to the walls of the separation tank, forming an oil film. Over time, this film is prone to deterioration and bacterial growth. Furthermore, the oil film on the walls can interfere with the upward path of oil droplets, reducing the oil-water separation effect and causing a continuous decline in the separation efficiency of oily wastewater.

[0004] Therefore, we propose an intelligent temperature-controlled oil-water separation and lifting integrated device to solve the problems mentioned in the background technology. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent temperature-controlled integrated oil-water separation and lifting device to solve the problems mentioned in the background art, such as oil floating and converging during oil-water separation of oily wastewater, with some oil adhering to the wall of the separation tank to form an oil film, which is prone to deterioration and bacterial growth over time. The oil film on the wall also interferes with the upward path of oil droplets, reducing the oil-water separation effect and causing a continuous decline in separation efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, the present invention employs a fan and heater to deliver hot air. A ring-shaped air channel is formed by circumferentially distributed arc-shaped air strips. The ejected hot airflow creates a ring-shaped hot air curtain, heating the oil film on the chamber wall. Simultaneously, the airflow shear force pushes the oil on the wall surface downwards. Then, the first electric actuator pushes the ring plate, hot air curtain, and flexible scraper downwards, mechanically scraping away the air-push cleaned chamber wall, achieving full circumferential coverage cleaning. By integrating the air curtain oil removal mechanism and the moving oil scraping mechanism, a single-stage synergistic oil removal process of "thermal softening air-push + mechanical scraping" is achieved. The hot air curtain softens and pre-pushes the oil film, significantly reducing the resistance of mechanical scraping. The flexible scraper makes flexible contact with the chamber wall, and with the pretreatment of the hot air curtain, there is no hard friction damage. It is linked with the intelligent control system without manual intervention, adapting to the overall automated operation requirements of the equipment.

[0017] 2. In use, the forward and reverse motors and the drive gear work together to drive the inner and outer ring gears to rotate in opposite directions, causing the first and second latches to disengage from the ring buckles. The second electric push rod pulls the inclined tube upward, moving the air outlet of the arc-shaped air strip tube to the bottom of the flexible scraper. This allows for the thermal softening and airflow blowing away of the oil adhering to the bottom of the flexible scraper, achieving automated self-cleaning of the scraper. With the cooperation of the connecting mechanism, the air curtain oil removal mechanism and the moving oil scraping mechanism are optimized to achieve a two-stage synergy of "wall oil removal, scraper self-cleaning, and circumferential cleaning without dead angles." This eliminates the need for manual disassembly of the scraper to clean the adhering oil, ensuring the stability of the subsequent oil removal film effect.

[0018] 3. In use, the oil-water separation mechanism, the inlet sludge removal mechanism, and the sewage lifting mechanism are connected sequentially via sealed pipes, achieving fully automated and intelligent processing of the entire process, including sludge removal, oil-water separation, oil film cleaning, temperature control, oil level monitoring, and sewage lifting. This forms a complete oily wastewater treatment process, with each system working in synergy to significantly improve the overall processing efficiency and operational stability of the equipment. The micro-aeration system is located above the sedimentation zone, which improves oil-water separation efficiency without disturbing the sediment at the bottom, allowing the sediment to settle stably in the sedimentation zone for easy subsequent centralized cleaning.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-11As shown, the present invention provides a technical solution: an intelligent temperature-controlled oil-water separation and lifting integrated device, including an oil-water separation mechanism 1, a water inlet and slag removal mechanism 2, and a sewage lifting mechanism 3. The oil-water separation mechanism 1 is internally equipped with an air curtain oil removal mechanism 5, a moving oil scraping mechanism 6, and a connecting mechanism 7. The oil-water separation mechanism 1 includes a separation box 101, and an oil collection box 102 is fixedly connected to the top of the separation box 101. The air curtain oil removal mechanism 5 includes an annular pipe 503, a plurality of fixed pipes 504 are fixedly connected to the bottom of the annular pipe 503, a telescopic pipe 505 is fixedly connected to the bottom end of each of the plurality of fixed pipes 504, an inclined pipe 506 is fixedly connected to the bottom end of each of the plurality of telescopic pipes 505, and an arc-shaped air strip 507 is fixedly connected to one end of each of the plurality of inclined pipes 506. The plurality of arc-shaped air strips 507 are circumferentially distributed to form an annular air channel, which is used to spray an annular hot air curtain onto the inner wall of the oil collection box 102 to reduce the viscosity of the residual oil film, enhance fluidity, and use airflow to drive the oil to flow to the oil collection area. The movable oil scraping mechanism 6 includes an annular plate 603, with an annular groove 605 inside the annular plate 603. A flexible scraper 604 is fixedly installed on the outer surface of the annular plate 603 for cleaning the inner wall of the oil collection tank 102 after the hot air curtain oil removal and scraping off the residual oil film. Two first electric push rods 602 are fixedly installed on the top of the annular plate 603 near the inner wall, and two second electric push rods 606 are symmetrically installed on the top of the annular plate 603. Each of the two second electric actuators 606 has a lifting plate 607 fixedly installed at its top end, and two fixing posts 608 fixedly installed at the bottom of each of the two lifting plates 607. A fixing ring 610 is fixedly installed at the bottom of each of the four fixing posts 608. The second electric actuator 606 pulls the fixing ring 610 upward through the lifting plate 607 and the fixing posts 608, which drives the inclined tube 506 upward, so that the arc-shaped air strip tube 507 moves to the bottom of the flexible scraper 604. The residual oil adhering to the bottom of the flexible scraper 604 is cleaned by the hot air curtain. Multiple ring buckles 611 are fixedly installed on the outer surface and inner wall of the fixing ring 610. A fan 501 is fixedly installed on the rear surface of the top of the separator 101. The air outlet of the fan 501 is connected to a heater 502 through a pipe. The air chamber of the arc-shaped air strip pipe 507 is set at an angle, and the air outlet faces the inner wall of the oil collection tank 102. The heater 502 is installed on the rear surface of the oil collection tank 102 through an auxiliary component. The output end of the heater 502 is fixedly connected to the input end of the annular pipe 503 through a pipe.The outer surface of the annular tube 503 is mounted on the top of the tank cover 103 via an auxiliary block. The bottom ends of multiple fixed tubes 504 are fixedly inserted into the interior of the tank cover 103. The outer surfaces of multiple inclined tubes 506 are movably embedded in the interior of the annular groove 605, and the top ends of multiple inclined tubes 506 are movably inserted into the top of the annular plate 603. The outer surface of the flexible scraper 604 is in contact with the inner wall of the oil collection tank 102, and the flexible scraper 604 is located above the arc-shaped air strip tube 507. The top ends of the two first electric push rods 602 are movably inserted into the top of the tank cover 103. Two mounting brackets 601 are fixedly installed on the top of the tank cover 103. Two movable holes 609 are opened on the top of each of the two lifting plates 607. The outer surfaces of the four telescopic tubes 505 are respectively movably embedded in the four movable holes 609. The top ends of the two first electric push rods 602 are respectively fixedly installed on the top surface inside the two mounting brackets 601. The bottom ends of the four fixed columns 608 are movably inserted through the annular plate 603 into the annular groove 605. The outer surface of the fixed ring 610 is movably embedded in the annular groove 605. The outer surfaces of the multiple inclined tubes 506 are all fixedly installed inside the fixed ring 610.

[0023] In this embodiment, during use, the oil accumulated in the oil collection tank 102 is drained through the oil drain pipe 107. The oil level sensor 109 detects the oil level. When the oil level drops to the set target, the air curtain oil removal mechanism 5 and the moving oil scraping mechanism 6 are activated in sequence. The blower 501 delivers air to the heater 502 for heating. After becoming hot air, it is delivered through the pipe to the annular pipe 503, and then sequentially through the fixed pipe 504, the telescopic pipe 505, and the inclined pipe 506 to the arc-shaped air strip pipe 507. The air outlet of the arc-shaped air strip pipe 507 is precisely oriented towards the wall of the oil collection tank 102. The circumferentially distributed arc-shaped air strip pipes 507 form an annular air channel. The ejected hot airflow forms an annular hot air curtain, which is then sprayed onto the tank wall to heat the oil film on the tank wall. The heat effect reduces the viscosity of the oil film and enhances its fluidity. At the same time, the airflow shear force pushes the oil on the wall surface downwards, converging into the oil below, and then being discharged. Next, the two first electric actuators 602 are activated, pushing the annular plate 603 and the flexible scraper 604 downward. The fixed ring 610 is connected to the annular plate 603 through the connecting mechanism 7, which in turn drives the arc-shaped air strip tube 507 that forms the annular air passage to move downward. The telescopic tube 505 is gradually extended. During this process, the hot air curtain cleans the oil film on the box wall in a downward movement state. The flexible scraper 604 moves synchronously to perform a secondary cleaning on the box wall after the air push, scraping away the residual oil and causing it to collect in the oil below, further improving the oil film cleaning effect, keeping the box wall clean and hygienic, and achieving circumferential full coverage cleaning. By integrating the air curtain oil removal mechanism 5 and the mobile scraping mechanism 6, a first-level synergistic oil removal process of "thermal softening air propulsion + mechanical scraping" is achieved. The hot air curtain softens and pre-pushes the oil film, significantly reducing the resistance of mechanical scraping. Compared with single mechanical scraping, the oil film cleaning efficiency is greatly improved, avoiding the problems of oil film residue and scraper wear caused by hard scraping. The flexible scraper 604 makes flexible contact with the tank wall. With the pretreatment of the hot air curtain, there is no hard friction damage, which extends the service life of the tank wall and the flexible scraper 604. It is linked with the intelligent control system 4 without manual intervention, adapting to the overall automated operation requirements of the equipment. It not only achieves maximum oil discharge, but also avoids oil film adhering to the tank wall to form dirt, breed bacteria, and affect subsequent oil-water separation. It solves the problem that when oily wastewater is separated into oil and water, the oil floats and gathers, and some oil adheres to the tank wall of the separation tank to form an oil film. Over time, the oil film on the wall is prone to deterioration and bacterial growth. The oil film on the wall can also interfere with the floating path of oil droplets, reduce the oil-water separation effect, and cause the separation efficiency to continue to decline.

[0024] Example 2: Figures 4-11As shown, the oil-water separation mechanism 1 is internally equipped with an air curtain oil removal mechanism 5, a movable oil scraping mechanism 6, and a connecting mechanism 7. The movable oil scraping mechanism 6 includes an annular plate 603, with an annular groove 605 inside the annular plate 603. A flexible scraper 604 is fixedly installed on the outer surface of the annular plate 603 for cleaning the inner wall of the oil collection tank 102 after the hot air curtain oil removal and scraping off the residual oil film. Two first electric push rods 602 are fixedly installed on the top of the annular plate 603 near the inner wall, and two second electric push rods 606 are symmetrically installed on the top of the annular plate 603. Each of the two second electric actuators 606 has a lifting plate 607 fixedly installed at its top end, and two fixing posts 608 fixedly installed at the bottom of each of the two lifting plates 607. A fixing ring 610 is fixedly installed at the bottom of each of the four fixing posts 608. The second electric actuator 606 pulls the fixing ring 610 upward through the lifting plate 607 and the fixing posts 608, which drives the inclined tube 506 upward, so that the arc-shaped air strip tube 507 moves to the bottom of the flexible scraper 604. The residual oil adhering to the bottom of the flexible scraper 604 is cleaned by the hot air curtain. Multiple ring buckles 611 are fixedly installed on the outer surface and inner wall of the fixing ring 610. The connecting mechanism 7 includes a forward and reverse motor 701. A drive gear 702 is fixedly mounted on the output end of the forward and reverse motor 701. An inner ring gear 703 and an outer ring gear 704 mesh with the outer surface of the drive gear 702. Multiple first latches 705 are fixedly mounted at the bottom of the outer surface of the inner ring gear 703, and multiple second latches 706 are fixedly mounted on the bottom surface of the inner wall of the outer ring gear 704. One end of each of the first latches 705 and the second latches 706 is movably embedded inside multiple ring latches 611. The forward and reverse motor 701 is secured by bolts. Mounted on the top of the annular plate 603, the output end of the forward and reverse motor 701 extends movably into the interior of the annular groove 605. The outer surface of the drive gear 702 is movably embedded in the interior of the annular groove 605. The inner ring gear 703 and the outer ring gear 704 are both movably embedded in the interior of the annular groove 605. Limiting grooves 707 are provided at the top and bottom of the inner ring gear 703 and the outer ring gear 704. Limiting strips 708 are movably embedded in the interior of the four limiting grooves 707. The four limiting strips 708 are respectively fixedly installed on the top and bottom surfaces inside the annular groove 605.

[0025] In this embodiment, during use, when the output end of the first electric actuator 602 is fully extended, it will automatically pause for a while. At this time, both the hot air curtain and the flexible scraper 604 move to the oil drain pipe 107. Then, the air curtain oil removal mechanism 5 pauses for a while and stops the output of the hot air curtain. Next, the forward and reverse motors 701 start, driving the drive gear 702 to rotate, which in turn drives the inner ring gear 703 and the outer ring gear 704 to rotate in opposite directions, causing the first latch 705 and the second latch 706 to rotate in opposite directions and rotate out of the ring latch 611. At this time, the fixed ring 610 loses its engagement with the annular plate 603. Then, the two second electric actuators 606 start, pulling the fixed ring 610 upward in the annular groove 605 through the lifting plate 607 and the fixed column 608, which in turn drives the multiple inclined tubes 506 and the arc-shaped air strip tubes 507 to move upward. When the second electric actuator 606 automatically closes, the fixed ring 610 moves to a position close to below the drive gear 702, and the air outlet of the arc-shaped air strip tube 507 moves to the bottom of the flexible scraper 604. The air curtain degreasing mechanism 5 resumes operation and continues to output an annular hot air curtain. At this time, the hot air curtain blows towards the bottom of the flexible scraper 604, softening the oil adhering to the bottom of the flexible scraper 604 with heat and airflow to remove it, realizing automatic self-cleaning of the scraper and preventing it from adhering to the box wall again when the flexible scraper 604 is reset, thus avoiding contamination. After the cleaning of the flexible scraper 604 is completed, the second electric actuator 606 drives the fixed ring 610 to move downwards to reset, driving the arc-shaped air strip tube 507 to move and reset. The forward and reverse motor 701 starts again, and its output end rotates in the opposite direction, driving the first latch 705 and the second latch 706 to rotate in the opposite direction, and inserting them into the ring latch 611 again, realizing the engagement between the fixed ring 610 and the annular plate 603. Finally, the first electric push rod 602 pulls the annular plate 603 upward to reset, causing the air curtain oil removal mechanism 5 and the flexible scraper 604 to reset. With the cooperation of the connecting mechanism 7, the air curtain oil removal mechanism 5 and the moving scraper mechanism 6 are optimized to achieve a two-stage synergy of "tank wall oil removal, scraper self-cleaning, and circumferential no-dead-angle cleaning", achieving no-dead-angle cleaning of the inner wall of the oil collection tank 102. There is no need to manually disassemble the scraper to clean the adhering oil. Automated self-cleaning is achieved through the hot air curtain, ensuring the stability of the subsequent oil removal film effect.

[0026] Example 3: Figures 1-3As shown, the oil-water separation mechanism 1 includes a separation tank 101, an oil collection tank 102 fixedly connected to the top of the separation tank 101, an intelligent control system 4 installed on the front surface of the top of the separation tank 101, a micro-aeration system 108 installed inside the separation tank 101, and the micro-aeration system 108 located above the sedimentation area at the bottom of the separation tank 101. A tank cover 103 is bolted to the top of the oil collection tank 102, an agitator 104 is installed inside the tank cover 103, and a temperature sensor 105 is installed at the bottom of the outer surface of the oil collection tank 102. An electric heating system 106 is installed on the top surface inside the separation tank 101, an oil drain pipe 107 is fixedly connected to the outer surface of the oil collection tank 102, an oil level sensor 109 is installed inside the tank cover 103, and the bottom ends of the oil level sensor 109 and the agitator 104 are both located inside the oil collection tank 102. The oil-water separation mechanism 1, the water inlet sludge removal mechanism 2, and the sewage lifting mechanism 3 are connected by pipes.

[0027] In this embodiment, during use, wastewater enters the inlet slag removal mechanism 2 to remove solid residues and is discharged into the slag collection bucket. Then, the wastewater enters the oil-water separation mechanism 1 through a connecting pipe for oil-water separation. Finally, the treated clean water enters the wastewater lifting mechanism 3 through a pipe, which automatically lifts the wastewater to the subsequent treatment unit. After the wastewater enters the separation tank 101, the flow rate decreases. Utilizing the density difference between oil and water, the oil naturally floats to the surface. At the same time, the micro-aeration system 108 generates microbubbles. These microbubbles adhere to the surface of the micro oil droplets, increasing the buoyancy of the oil droplets and accelerating their upward convergence, thus improving the oil-water separation efficiency. At this time, the oil accumulates in the oil collection tank 102. The oil level sensor 109 monitors the oil layer thickness. When the set value is reached, the oil drain pipe 107 is automatically opened, and the waste oil is discharged into the oil collection bucket. The temperature sensor 105 monitors in real time. When the temperature is lower than the set value, the electric heating system 106 and the stirrer 104 are automatically activated to prevent the oil from solidifying and clumping, ensuring smooth oil discharge. The intelligent control system 4 provides fully automatic control, real-time monitoring of temperature, oil level, water level, and pump operating status, automatic alarm for abnormalities, and supports remote monitoring and data recording. The oil-water separation mechanism 1, the inlet slag removal mechanism 2, and the sewage lifting mechanism 3 are all connected sequentially through sealed pipes, realizing fully automated and intelligent processing of slag removal, oil-water separation, oil film cleaning, temperature control, oil level monitoring, and sewage lifting, forming a complete oily wastewater treatment process. The coordinated operation of each system significantly improves the overall processing efficiency and operational stability of the equipment.

[0028] Furthermore, the micro-aeration system 108 is located above the lower sedimentation zone of the separation box 101, which not only improves the oil-water separation efficiency, but also does not disturb the sediment in the bottom sedimentation zone, thus affecting the oil-water separation effect, and allows the sediment to settle stably in the sedimentation zone, making it easier for subsequent centralized cleaning.

[0029] The overall effect and working principle of the mechanism are as follows: the inlet slag removal mechanism 2 removes solid residue from the sewage, the sewage enters the oil-water separation mechanism 1 for oil-water separation, and finally the sewage lifting mechanism 3 automatically lifts the sewage to the subsequent treatment unit. After the sewage enters the separation tank 101, oil and water are separated. The micro-aeration generation system 108 generates micro-bubbles to accelerate the upward floating and aggregation of oil droplets. The oil level sensor 109 monitors the oil layer thickness. When the set value is reached, the oil drain pipe 107 is automatically opened, and the waste oil is discharged into the oil collection tank. The temperature sensor 105 monitors in real time. When the temperature is lower than the set value, the electric heating system 106 and the agitator 104 are automatically activated to prevent the grease from solidifying and clumping. When the oil level drops to the set target, the blower 501 delivers air to the heater 502 for heating. The hot air is sequentially delivered to the annular pipe 503, fixed pipe 504, telescopic pipe 505, inclined pipe 506, and arc-shaped air strip pipe 507. The sprayed hot air curtain heats the oil film on the tank wall, reducing the oil film viscosity and enhancing its fluidity. At the same time, the airflow shear force pushes the oil downward to be discharged. The first electric actuator 602 pushes the annular plate 603, arc-shaped air strip pipe 507, and flexible scraper 604 downward to achieve dynamic thermal softening air propulsion and mechanical scraping. When the first electric push rod 602 automatically pauses, the air curtain oil removal mechanism 5 pauses for a while, the forward and reverse motor 701 starts, driving the drive gear 702 to rotate. Through the inner ring gear 703 and the outer ring gear 704, the first buckle 705 and the second buckle 706 rotate in opposite directions and turn out from the ring buckle 611. The second electric push rod 606 pulls the fixed ring 610 to move upward, driving the inclined tube 506 and the arc-shaped air strip tube 507 to move upward, so that the air outlet of the arc-shaped air strip tube 507 moves to the bottom of the flexible scraper 604, and performs thermal softening and airflow blowing off the oil adhering to the bottom of the flexible scraper 604, realizing the automatic self-cleaning of the scraper. Finally, the second electric push rod 606 drives the arc-shaped air strip tube 507 to move and reset, and the forward and reverse motors 701 drive the first buckle 705 and the second buckle 706 to re-insert into the ring buckle 611. The first electric push rod 602 pulls the annular plate 603 to reset, so that the air curtain oil removal mechanism 5 and the flexible scraper 604 are reset.

[0030] Among them, the agitator 104, temperature sensor 105, electric heating system 106, micro-aeration generation system 108, oil level sensor 109, water inlet slag removal mechanism 2, sewage lifting mechanism 3, intelligent control system 4, blower 501, heater 502, first electric actuator 602, second electric actuator 606 and forward and reverse motor 701 are all existing technologies, and their components and operating principles are all publicly available technologies, which will not be explained in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
