[0002] Oily kitchen waste is widely generated in restaurant kitchens, food processing workshops and other scenarios.

Therefore, an efficient and stable oil-water separation device is needed to meet actual production needs.

[0003] Existing oil-water separation devices mostly rely on natural settling and stratification, collecting floating oil through simple structures such as scrapers or using ordinary filters. However, they have significant shortcomings: low separation efficiency, relying solely on natural buoyancy for stratification makes rapid and thorough separation difficult; poor oil adsorption and cleaning effects, lacking targeted coagulation and adsorption structures, failing to utilize the difference in freezing points between oil and water to enhance separation, resulting in significant oil residue and complex cleaning; and the failure to consider the impact of water temperature on oil coagulation and adsorption, making the separation effect easily reduced by water temperature changes, unable to guarantee a stable and efficient oil-water separation process, and failing to meet the high requirements of actual production for separation efficiency and effectiveness.

[0038] 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.

[0039] Reference Figures 5 to 8This invention provides an oil-water separation device for oily kitchen waste, comprising a rotating roller 35 driven by a gear 26, which rotates to move an arc-shaped plate 8 and an arc-shaped plate 9, thus initiating the subsequent movement of the adsorption fan 15 and oil adsorption action, and opening the mechanical process of oil adsorption and separation. The arc-shaped plate 8 is externally connected to the rotating roller 35 and moves with the rotation of the roller 35, driving the sliding rod 10 to rotate. This, in conjunction with the groove of the limiting ring 7, allows for the folding and resetting of the arc-shaped plate 9, providing a linkage basis for the adjustment of the adsorption fan 15 position, oil adsorption, and subsequent cleaning. The arc-shaped plate 9, externally connected to the arc-shaped plate 8, moves with the rotating roller 35, driving the adsorption fan 15 to rotate towards the floating oil. The area, while changing shape through folding and resetting, pulls the adsorption fan plate 15 to complete oil adsorption and the movement of the inclined scraper 33, which is the direct driving component for the movement of the adsorption fan plate 15. The external rotating connection of the arc plate 2 9 is connected to the adsorption fan plate 15, which rotates to the floating oil area under the drive of the arc plate 2 9. It expands the contact area with the oil by relying on its own shape, and provides an installation carrier for the cooling adsorption plate 16. It achieves precise adsorption and coverage of oil through position movement, which is the execution structure of oil adsorption. The internal top of the adsorption fan plate 15 is fixedly connected to the cooling adsorption plate 16. Utilizing the physical property that the freezing point of oil is higher than that of water, the cooling plate with filter holes allows the oil to solidify on the surface after contact. The filter holes allow water to pass through, achieving preliminary separation of oil and water. It is the core component of oil solidification adsorption based on physical properties.

[0040] The internal structure of the adsorption fan plate 15 includes a built-in sliding block 18 and a rubber stop 19 in the airflow sleeve 17. When the adsorption fan plate 15 resets and contacts the rotating roller 35, it triggers gas to rush out and clean the cooling adsorption plate 16. The rubber stop 19 is reset and drawn in by the elastic telescopic rod 20. This, along with the air pipe 21 and spring 22, maintains gas stability and serves as the airflow control chamber for cleaning the cooling adsorption plate 16. Multiple sliding blocks 18 are slidably connected inside the airflow sleeve 17. When the adsorption fan plate 15 resets, they are squeezed and slide, causing the rubber stop 19 to move and controlling the gas to rush out of the airflow sleeve 17. This provides the airflow power for cleaning the cooling adsorption plate 16 and acts as a linkage trigger for airflow control. One end of the moving block 18 is fixedly connected to a rubber stop 19. As the sliding block 18 moves, it changes the internal space of the airflow sleeve 17, enabling gas to rush out to clean and cool the adsorption plate 16 and to maintain gas reserves by suction and reset. It is the control valve for airflow in and out. The bottom end of the rubber stop 19 is fixedly connected to multiple elastic telescopic rods 20. When the arc plate 29 pulls the adsorption fan plate 15, the elasticity is used to reset the rubber stop 19, which stores gas for the airflow sleeve 17 to suction and for subsequent cleaning actions, ensuring the cleaning process cycle. It is the elastic power source for the reset of the rubber stop 19. The outside of the sliding block 18 is slidably connected to the outside of the adsorption fan plate 15, and the right end of the elastic telescopic rod 20 is fixedly connected to the right end of the inner wall of the adsorption fan plate 15.

[0041] Both the top and bottom ends of the airflow sleeve 17 are equipped with air delivery mechanisms. These mechanisms include multiple air pipes 21 connecting the airflow sleeve 17 to the cooling adsorption plate 16. The top air pipe 21 guides the ejected gas to the cooling adsorption plate 16 for impact cleaning. The bottom air pipe 21 draws in and stores air when the rubber stop 19 is reset. This serves as a channel structure for airflow transmission and cleaning execution. The adjacent ends of the multiple air pipes 21 are fixedly connected to the top and bottom ends of the airflow sleeve 17. Rubber blocks 23 are slidably connected inside the air pipes 21, allowing them to slide within the pipes. The spring 22, in conjunction with the second spring, enables unidirectional airflow, ensuring orderly intake and exhaust of the airflow sleeve 17 and maintaining internal gas stability. It is a valve core structure for unidirectional airflow control. The top of the rubber block 23 is fixedly connected to the air pipe 21 built into the spring 22. When the rubber block 23 is used to control unidirectional airflow, one rubber block 23 remains stationary, maintaining stable gas reserves in the airflow sleeve 17 and ensuring continuous power for cleaning the cooling adsorption plate 16. The top of the spring 22 is fixedly connected to the top of the inner wall of the air pipe 21.

[0042] A sliding rod 10 is rotatably connected to one end of the arc-shaped plate 8 and the arc-shaped plate 9. During the movement of the arc-shaped plates, the rod rotates and slides, guiding the arc-shaped plates 8 and 9 to fold in conjunction with the groove of the limiting ring 7. Resetting is achieved with the help of the fixed block 11 and spring 12, and the position of the adsorption fan plate 15 is adjusted accordingly. This rod serves as the transmission and reset rod for mechanical movement. A fixed block 11 is fixedly connected to the outside of the sliding rod 10, fitted onto it. Utilizing the elasticity of the spring 12, when the limiting rod 13 touches the groove partition, it pushes the sliding rod 10 out to reset, providing elastic power for the resetting of the arc-shaped plate and the adsorption fan plate 15. This acts as the elastic trigger for the resetting action. A spring 12 is fitted outside the sliding rod 10, assisting the fixed block 11 in resetting the sliding rod 10. This provides continuous elastic support for the resetting of the arc-shaped plate and the adsorption fan plate 15, ensuring stable and repeatable resetting action. This spring 12 is the elastic carrier of the resetting power. A rotating ring 14 connects the sliding rod 10 and the connecting pipe 2 via a sliding connection. This ring stabilizes the movement of the sliding rod 10 and seals the port of the connecting pipe 2, ensuring the airflow environment within the connecting pipe 2. It serves as a dual guarantee for the stability of the sliding rod 10's movement and the sealing of the connecting pipe 2. A limiting rod 13 is fixedly connected to the bottom of the sliding rod 10 and moves with it, sliding within the groove of the limiting ring 7. The travel of the sliding rod 10 is controlled by the groove trajectory, allowing the arc plate to complete its folding action and providing a trigger condition for resetting. This limiting element serves as a motion guide and travel control component. One end of the spring 12 is fixedly connected to the bottom of the fixed circular block 11, and the other end of the spring 12 is fixedly connected to the outside of the rotating ring 14. Two limiting rings 7 are slidably connected to the outside of the sliding rod 10, with the internal grooves providing a sliding path for the limiting rod 13. Through the groove partition and other structures, the folding and resetting actions of the sliding rod 10 and the arc plate are standardized, ensuring the orderly movement of the machinery. This serves as a standardized framework for the motion trajectory.

[0043] Reference Figures 1 to 3 Two limiting rings 7 are externally fixedly connected to two support plates 6. The support plates 6 are externally fixedly connected to connecting pipes 2, providing installation space for the fan 5. Cooling is achieved through airflow, and the connecting structure ensures cooling of the space at the bottom of the arc-shaped plate, assisting in maintaining the operating environment of the cooling adsorption plate 16. It serves as the airflow channel and structural connector. The sliding rod 10 is externally slidably connected to the near ends of the two connecting pipes 2. The rotating ring 14 is internally rotatably connected to the near ends of the two connecting pipes 2. The limiting rod 13 is externally slidably connected to the inside of the two limiting rings 7. Support blocks 4 are fixedly connected to the far ends of the two connecting pipes 2, providing installation support for the fan 5 and ensuring stable operation of the fan 5. This is the foundation for the operation of the fan 5. The supporting block 4 is equipped with a fan 5 inside to circulate and cool the air inside the connecting pipe 2, while simultaneously cooling the space at the bottom of the arc-shaped plate. This provides a stable low-temperature environment for cooling the adsorption plate 16, ensuring the oil solidification and adsorption effect. It is the source of environmental cooling. Filter plates 3 are fixedly connected to the far ends of the two connecting pipes 2 and installed at the ports of the connecting pipes 2. These filters impurities in the air entering the connecting pipes 2, preventing blockage of the fan 5 and affecting airflow, and ensuring clean airflow inside the device. They are the guardians of airflow cleanliness. The supporting shell 1 is fixedly connected to the outside of the two connecting pipes 2 as the core carrier of the device. It contains clean water and oil-water mixtures, and provides installation space for all functional components such as the motor 24, rotating roller 35, and arc-shaped plate. It constructs a closed and separated environment and serves as the carrier frame of the entire device.

[0044] The front end of the support shell 1 is fixedly connected to a motor 24, which outputs continuous rotational power to provide initial power for gear transmission, rotating roller 35, and subsequent mechanical movement. It is the power heart of the device's mechanical action, driving the mechanical links of the separation process. The drive end of the motor 24 is fixedly connected to a gear 1 25, which receives the power of the motor 24 and transmits the rotational power to a gear 2 26 through meshing transmission, realizing power conversion and transmission. It is the intermediate gear for transferring the power from the motor 24 to the rotating roller 35. The front end of the rotating roller 35 is fixedly connected to a gear 2 26, which receives the power of the gear 1 25 and rotates, directly driving the rotating roller 35 to rotate, completing the secondary power transmission and allowing the rotating roller 35 to obtain continuous rotational power. It is a key transmission component of the mechanical motion chain. Gear 1 25 and gear 2 26 are meshed. The inside of gear 2 26 is rotatably connected to the outside of one of the connecting pipes 2. The left end of the support shell 1 is fixedly connected to the front and rear ends of the collection box 34, and the front and rear ends of the rotating roller 35 are rotatably connected to the inside of the support shell 1.

[0045] Reference Figures 2 to 4A water inlet pipe 27 is fixedly connected to the right end of the support shell 1 to inject clean water into the support shell 1, providing an initial liquid environment for oil-water separation. By controlling the water injection volume and precisely adjusting the water level with the observation window 32, it is ensured that the oil can float stably on the water surface after the oil and water are mixed. This is the basic preparatory structure for the separation process. An oil sludge pipe 28 is fixedly connected inside the support shell 1 to transport oily kitchen waste liquid to the support shell 1, allowing the oil and water to enter the preset separation space. Utilizing the density difference between oil and water, the oil naturally floats on the surface of the clean water, initiating the physical stratification process of oil-water separation. This is a crucial channel for oil-water introduction. A water pump 29 is fixedly connected to the bottom right end of the support shell 1. Through the first exchange pipe 30, water circulates within the support shell 1, accelerating the flow rate and preventing the water temperature from dropping due to oil condensation. This maintains the water temperature environment required for oil-water separation, ensuring efficient oil solidification and adsorption. It also acts as a water temperature stabilizer. The output end of the water pump 29 is fixedly connected to the first exchange pipe 30, guiding the water circulation. This, combined with the second exchange pipe 31, achieves alternating water flow within the support shell 1, enhancing flow rate control. This serves as the output channel for water circulation. The input end of pump 29 is fixedly connected to exchange pipe 21, which is connected to the input end of pump 29. This exchange pipe 21, along with exchange pipe 1 30, completes the water flow alternation, accelerates the water flow speed inside the support shell 1, and prevents abnormal water temperature drop. It serves as the input channel for water circulation. An inclined scraper 33 is slidably connected to the outside of the rotating roller 35. When the adsorption fan plate 15 moves and resets, it scrapes off the solidified oil on the surface of the cooling adsorption plate 16 using the resetting force, achieving oil collection and transfer. This is a key structure for the physical cleaning and collection after oil separation. A collection box 34 is fixedly connected to the left end of the inclined scraper 33 for collection. The solidified oil scraped off by the inclined scraper 33 enables centralized storage and subsequent recovery of the oil. It is the final collection structure after oil separation. The left end of the first exchange pipe 30 is externally fixed to the inside of the support shell 1, and the left end of the second exchange pipe 31 is externally fixed to the inside of the support shell 1. The rear end of the support shell 1 is equipped with an observation window 32 to visually display the water level inside the support shell 1, allowing operators to accurately judge whether the water injection meets the standard, providing a basis for the amount of water injected for the oil-water mixture, ensuring the stability of the natural oil floating layer, and is a key structure for visual water level monitoring.

[0046] Working principle: First, clean water is placed into the support shell 1 through the inlet pipe 27. After observing through the observation window 32 that the water has reached the appropriate level, the oil-water mixture (oil and kitchen waste liquid) is transported into the support shell 1 through the oil pipe 28. Because oil is less dense than water, the oil-water mixture floats on the surface of the clean water when it is transported into the support shell 1. The motor 24 is started, which drives the rotation of gear 25. Gear 25 and gear 26 are meshed, and the rotation of gear 25 drives the gears... The rotation of wheel 26 drives the rotation of rotating roller 35 through the rotation of gear 26. The rotation of rotating roller 35 drives the movement of arc plate 8 and arc plate 9. The movement of arc plate 9 drives the rotation of adsorption fan plate 15. When adsorption fan plate 15 transfers oil floating on the water surface, cooling adsorption plate 16 is a cooling plate with fine filter holes. Because the freezing point of oil is higher than that of water, when oil comes into contact with cooling adsorption plate 16, it solidifies on the outer surface of cooling adsorption plate 16.

[0047] When the arc-shaped plate 8 and the arc-shaped plate 9 move, they cause the sliding rod 10 to rotate externally at the near end of the two connecting pipes 2, and cause the limiting rod 13 to slide in the inner groove of the limiting ring 7. The groove inside the limiting ring 7 causes the sliding rod 10 to slide inward when it moves, thereby causing the near end of the arc-shaped plate 8 and the arc-shaped plate 9 to fold inward. The movement of the arc-shaped plate 9 causes the adsorption fan plate 15 to move in the direction of the folding of the arc-shaped plate 9, thereby achieving the opposite position of the adsorption fan plate 15 when the rotating roller 35 moves. The position is moved, and when the limiting rod 13 slides to the partition in the groove of the limiting ring 7, the elasticity of the fixed round block 11 sleeved on the outside of the sliding rod 10 and the limiting of the spring 12 make the sliding rod 10 push upward. When the sliding rod 10 is pushed out, the arc plate 8 and the arc plate 9 are reset, so that the outside of the adsorption fan plate 15 and the cooling adsorption plate 16 moves to the scraper plate 33. With the force of reset, the shaking of the rotating roller 35 and the adsorption fan plate 15 shakes off the water stains on the part that is in contact with the oil-water mixture.

[0048] An airflow sleeve 17 is provided inside the adsorption fan plate 15. When the adsorption fan plate 15 is reset and comes into contact with the outside of the rotating roller 35, the sliding block 18 is pushed up and slides inside the airflow sleeve 17. The movement of the sliding block 18 drives the movement of the rubber baffle 19, which in turn pushes out the gas stored inside the airflow sleeve 17. The gas impacts the cooling adsorption plate 16 through multiple air pipes 21 fixedly connected to the top of the airflow sleeve 17, making the cleaning of the cooling adsorption plate 16 more stable. The moisture absorbed when the oil solidifies also flows out through the venting groove at the top of the airflow sleeve 17. When the arc plate 29 pulls the adsorption fan plate 15 to move, the elasticity of the elastic telescopic rod 20 resets the rubber block 19. When the rubber block 19 resets, the air pipe 21 at the bottom of the airflow sleeve 17 draws in gas, causing it to impact the cooling adsorption plate 16. Inside the two air pipes 21, there are springs 22 and rubber blocks 23. While drawing in and expelling gas, one of the rubber blocks 23 remains stationary, keeping the gas storage inside the airflow sleeve 17 stable.

[0049] The water pump 29 installed outside the support shell 1 mainly functions to alternate the water flow inside the support shell 1 through the exchange pipe 1 30 and the exchange pipe 2 31, thereby accelerating the water flow rate inside the support shell 1 and preventing the water temperature inside the support shell 1 from dropping when the oil is condensed. The fan 5 is installed to circulate and cool the air inside the connecting pipe 2, while also cooling the space formed at the bottom of the arc plate 1 8 and the arc plate 2 9, thus ensuring the stability of the cooling adsorption plate 16 during operation. The rotating ring 14 is set to make the movement of the sliding rod 10 more stable and to seal and connect the two connecting pipes 2.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
