Description

Technical Field

[0001] This invention relates to the field of oil-water separation technology, and in particular to an aggregated oil-water separator. Background Technology

[0002] Oil-water separation refers to the process of separating oil and water. In many industrial and environmental applications, mixtures of oil and water need to be separated so that the oil and water can be treated or recycled separately. There are many methods for oil-water separation, including gravity separation, centrifugation, flotation, filtration, and distillation. The specific method chosen depends on the properties of the oil-water mixture and the separation requirements.

[0003] Currently available aggregated oil-water separators have a slow rising speed, which affects separation efficiency. Oil and water are discharged simultaneously, and the oil contains a lot of water. In addition, existing aggregated oil-water separators produce waste residue and small particles during the separation process and do not have a good filtration function, resulting in poor separation quality and affecting the oil-water separation effect. Therefore, there is an urgent need for a new type of aggregated oil-water separator to solve these problems.

[0004] Chinese patent publication number "CN216141352U" discloses a cohesive oil-water separator, which includes a separator body, an operation panel, and a viewing window. The operation panel is located on one side wall of the separator body, and the viewing window is located below the operation panel. A water inlet pipe is located at the top of the separator body, and a water collection chamber is located inside the separator body below the water inlet pipe. The advantages are: this invention, through the inclusion of an air flotation machine, an oil skimmer, an oil discharge electric valve, and a water discharge electric valve, accelerates the upward movement of oil, improves oil-water separation efficiency, and ensures separate discharge of water and oil, minimizing water contamination during oil discharge. The honeycomb partition and filter screen effectively filter and remove waste residue and small particles from the oil and water, improving filtration efficiency, ensuring separation quality, and enhancing the overall oil-water separation effect.

[0005] During use, the aforementioned device employs a filter screen to assist in filtering and screening the oil-water mixture. While it can effectively filter waste residue, some residue inevitably remains on the filter screen. Over time, this residue will clog the filter screen, reducing its filtration efficiency and affecting the filtration rate. Furthermore, the air flotation machine at the bottom generates air bubbles that rise to the surface. These bubbles are highly prone to re-aggregating, further impacting the oil-water separation efficiency. Therefore, the aforementioned device has certain shortcomings and requires improvement.

[0006] Therefore, we propose an aggregated oil-water separator to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an aggregated oil-water separator to solve the problems mentioned in the background art, where waste residue inevitably remains on the filter screen during the separation and filtration process. Over time, the waste residue will inevitably cause the filter screen to become clogged, reducing the filtration efficiency and affecting the filtration rate. Furthermore, the bottom of the separator uses an air flotation machine to form air bubbles that float to the surface. These air bubbles are very easy to re-aggregate after being generated, thus affecting the oil-water separation efficiency.

[0013] In a further embodiment, the filtering mechanism includes a top frame, which is fixedly installed on the top of the separation box. Guide rails are fixedly installed on both sides and at both ends of the top frame. Sliding strips are slidably connected to the inner side of the guide rails. A filtering assembly is fixedly installed on the inner side of the sliding strips. A cleaning assembly is fixedly installed on the top of the filtering assembly.

[0014] In a further embodiment, a bridge-type handrail is fixedly installed between the tops of the slide bars, and a handrail sleeve is fixedly installed in the middle of the outer surface of the bridge-type handrail. The cross-sectional shape of both the slide bars and the guide rail is set to a convex shape, and wear-resistant pads are fixedly connected to the outer surface of the slide bars and the inner wall of the guide rail.

[0015] In a further embodiment, the filter assembly includes a filter screen and a trough. The filter screen is fixedly installed between the inner sides of the slide bar.

The second motor is fixedly installed on the upper end of the back of the separation tank, near the oil collection tank.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Firstly, in this invention, when oil separation is required, an oil-water mixture can be added to the inside of the top frame. A filter screen then assists in filtering large particles of impurities in the oil-water mixture, achieving a better oil filtration effect. Furthermore, during use, the inclined filter screen guides and discharges the filtered debris. As impurities accumulate, they naturally move along with the inclined filter screen, allowing them to be discharged through a trough into the conveying pipe and then into a waste collection box. Activating the first motor in the top housing drives a lead screw, which in turn moves a slider within the top housing. This slider then drives the cleaning screen to slide. The forward and reverse rotation of the first motor, combined with the flushing effect of the oil-water mixture during feeding, effectively discharges impurities from the outer surface of the filter screen into the waste collection box, preventing filter clogging and maintaining a high-efficiency filtration effect for an extended period.

[0020] Secondly, in this invention, wastewater is discharged into the top frame and filtered by the filter assembly in the top frame. The water then enters the bottom of the separation tank. At this point, the air pump is started, and the air generated by the air pump is discharged from top to bottom through the air guide pipe, the conveying horizontal pipe, and the exhaust pipe into the separation tank. At this point, the bubbles can float from bottom to top. By starting the waterproof motor, the rotating shaft is driven to rotate, which in turn drives the dispersing screen to rotate. The rotation of the dispersing screen further disperses the floating bubbles, promoting the mixing of the oil-water mixture and the bubbles, thereby promoting their air flotation separation and resulting in high air flotation efficiency.

[0021] Thirdly, in this invention, by setting a balancing mesh plate, the resistance of the water can be increased, so that the water stirred by the dispersing mesh plate can quickly reach equilibrium. After the air flotation is completed, the second motor is started, which drives the horizontal shaft to rotate. The horizontal shaft drives the skimming plate to rotate. At this time, as the skimming plate rotates, the oil foam floating on the top can be slowly conveyed to the trough. By tightening the trough, the skimmed oil can be discharged into the oil collection tank, so that the device can have a better oil separation effect. Attached Figure Description

By setting the slide bars 53 and the guide rail 52 to cooperate, the slide bars 53 can be pulled by pulling the bridge-type handrail 54, so as to facilitate and quickly remove the filter screen 561. The wear-resistant pads can improve the friction resistance of the slide bars 53 and the guide rail 52, so that the whole device has strong stability.

By setting the cleaning assembly 55, during use, the first motor 553 can drive the lead screw 552 to drive the slider 554 inside the guide rail 52 to slide. As the slider 554 slides, the cleaning brush plate 555 can move, and the filter screen 561 can be brushed with the cleaning brush, which can achieve a good cleaning effect on the filter screen 561.

[0041] Please see Figure 5 The oil skimmer 631 includes a horizontal shaft 6311, a second motor 6312, and an oil drain trough 6313. The horizontal shaft 6311 is rotatably connected to the upper end of the separation tank 4 inside the horizontal shaft 6311, near the oil collection tank 9. Oil skimmer plates 6314 are fixedly installed at equal intervals on the outer surface of the horizontal shaft 6311.

It is fixedly installed on the upper part of the back of the separator 4 near the oil collection tank 9; by setting the oil skimmer 631, the second motor 6312 can be started during the use of this equipment. The second motor 6312 drives the horizontal shaft 6311 to rotate, and the horizontal shaft 6311 drives the oil skimmer 6314 to rotate, which in turn drives the auxiliary oil skimmer, so that the oil can be quickly guided through the oil leakage tank 6313, making the oil easy to recover and treat, and making the use of this device convenient.

[0042] The working principle of this invention is as follows: By setting a filtration mechanism 5, the device allows the slide bar 53 to be inserted into the guide rail 52 during use, thereby installing the filter screen 561 inside the top frame 51. When oil separation is required, an oil-water mixture can be added to the top frame 51. The filter screen 561 then assists in filtering large particles of impurities in the oil-water mixture, achieving a better oil filtration effect. Furthermore, the inclined filter screen 561 guides and discharges filtered debris and impurities. As impurities accumulate, they naturally move along with the inclined filter screen 561. During operation, impurities and debris can be discharged through the trough 562 into the conveying pipe 563, and then into the waste collection box 11. During use, the first motor 553 in the top housing 551 drives the lead screw 552 to move the slider 554 within the top housing 551. This slider 554 then drives the cleaning screen to slide. The forward and reverse rotation of the first motor 553, combined with the flushing effect of the oil-water mixture during feeding, effectively discharges impurities from the outer surface of the filter screen 561 into the waste collection box 11, preventing clogging and maintaining high-efficiency filtration for extended periods. Furthermore, when further cleaning and maintenance of the filter screen 561 is required, it can be done by hand-holding the bridge. The handrail 54 pulls the slide bar 53 out from the inside of the guide rail 52, facilitating quick separation and replacement of the filter screen 561, thus improving the ease of use of this equipment. During use, by setting the separation mechanism 6, wastewater can be discharged into the top frame 51 and filtered by the filter component 56 in the top frame 51. At this time, the water enters the bottom of the separation tank 4. Then, by starting the air pump 613, the air pump 613 generates air that is discharged from top to bottom through the air guide pipe 614, the conveying horizontal pipe 612, and the exhaust pipe 615 into the interior of the separation tank 4. At this time, the air bubbles can float from bottom to top. By starting the waterproof motor 622, the rotating shaft 621 can be rotated. 1. Drive the dispersing screen 623 to rotate. This rotation further disperses the rising air bubbles, promoting mixing of the oil-water mixture and the air bubbles, thus facilitating air flotation separation and resulting in higher flotation efficiency. During use, a balancing screen 632 is installed to increase the resistance of the water, allowing the water agitated by the dispersing screen 623 to quickly reach equilibrium. After flotation is complete, the second motor 6312 is started. The second motor 6312 drives the horizontal shaft 6311 to rotate, which in turn drives the skimming plate 6314 to rotate. As the skimming plate 6314 rotates, the rising oil foam is slowly conveyed to the drain 562. Tightening the drain 562 discharges the skimmed oil into the oil collection tank 9.This device enables effective oil-liquid separation. When oil and water need to be removed, the oil drain valve 10 and water drain valve 8 can be opened to quickly discharge them. After use, when slag needs to be removed, the slag discharge valve 12 can be opened for slag removal, making the device convenient to use.
