Technical Field
[0001] This utility model relates to the field of oil recovery technology, and in particular to a drum scraper oil collection device. Background Technology
[0002] Oil-water separation equipment is an indispensable specialized device for oil-water separation in industrial production and catering kitchens, playing a key role in oil recovery, wastewater treatment, and environmental protection.
[0003] In existing technologies, traditional oil-water separation equipment generally uses belt-type oil scraping devices to achieve oil-water separation. These devices use a motor to drive a ring-shaped scraping belt to move continuously above the oil-water interface, utilizing the oil-adsorption properties of the belt's surface material to collect the oil. However, traditional belt-type oil scraping devices have shortcomings: the effective adsorption area of the scraping belt is limited by the belt's width and length, resulting in a limited surface area in contact with oil and water per unit time, making it difficult to overcome the bottleneck in oil adsorption efficiency; after the scraping belt adsorbs oil, the oil tends to remain on the belt, requiring manual separation, leading to low oil adsorption and separation efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the traditional oil separator uses a belt scraping method, which has a limited area for adsorbing oil, and the oil tends to remain on the belt, resulting in low oil adsorption and separation efficiency.
[0005] To solve the above-mentioned technical problems, this utility model provides a drum oil scraping and collecting device, which includes a support assembly, a drum assembly, and an oil scraping assembly. The support assembly includes a support; the drum assembly includes an oil-absorbing drum and an oil-absorbing layer. The oil-absorbing drum is connected to the support and can rotate about an axis parallel to the horizontal direction. The oil-absorbing layer is wrapped around the outer peripheral wall of the oil-absorbing drum; the oil scraping assembly includes a guide plate, an oil-blocking rubber plate, and an oil collecting groove. The oil collecting groove is located in the radial direction of the oil-absorbing drum. The guide plate is located on the side of the oil collecting groove close to the oil-absorbing drum, and the guide plate has a support surface that slopes downward along the oil-absorbing drum towards the oil collecting groove. The oil-blocking rubber plate is attached to the support surface and has an oil-guiding plane. One end of the oil-guiding plane protrudes from the support surface and abuts against the outer peripheral surface of the oil-absorbing layer, and the other end extends into the oil collecting groove.
[0006] In one embodiment, the oil-blocking rubber plate is tightly fixed to the outer wall of the guide plate by fasteners, and the oil-blocking rubber plate and the guide plate are detachably connected.
[0007] In one embodiment, there are multiple fasteners, which are arranged at intervals along the length of the oil-blocking rubber plate.
[0008] In one embodiment, an oil outlet is provided on the bottom outer wall of the oil collection tank for draining the oil in the oil collection tank.
[0009] In one embodiment, part of the oil-absorbing roller is submerged in oily wastewater, and the oil-absorbing layer is made of oleophilic and hydrophobic polypropylene.
[0010] In one embodiment, the downward-sloping end of the baffle extends into and is fixed to the edge of the oil collection tank.
[0011] In one embodiment, the oil-blocking rubber sheet is made of rubber.
[0012] In one embodiment, the drum oil scraping and collecting device further includes a drive mechanism, which includes a geared motor and a transmission component. The geared motor is located on one side of the oil suction drum and connected to it through the transmission component.
[0013] In one embodiment, the transmission component includes a driving gear, a driven gear, and a chain. The driven gear is located between the support and the oil suction drum and is connected to the oil suction drum via a rotating shaft. The output end of the geared motor is rotatably connected to the driving gear. The driving gear is connected to the driven gear via a chain and is used to drive the oil suction drum to rotate around a horizontally parallel axis.
[0014] Compared with existing technologies, the oil-collecting device based on this embodiment of the invention has the following advantages: Through the design of the oil-absorbing roller and oil-absorbing layer, the oil-absorbing roller has a larger outer peripheral wall area than traditional oil-scraping belts. Simultaneously, the oil-absorbing layer, wrapped around the outer wall of the oil-absorbing roller, has a larger oil adsorption area when rotating on the surface of the oily wastewater, effectively improving the efficiency of oil adsorption. The guide plate is located on the side of the oil collection trough near the oil-absorbing roller, and its supporting surface slopes downwards along the direction of the oil-absorbing roller towards the oil collection trough, providing a stable installation environment for the oil-blocking rubber plate. When the oil-blocking rubber plate is attached to the supporting surface, it can stably form a downwardly sloping flow channel. Utilizing gravity, the oil flows only towards the oil collection trough, allowing the scraped oil to flow smoothly into the trough along the guide plane, preventing oil residue on the oil-blocking rubber plate and improving the oil adsorption and separation efficiency of the device. Finally, the oil-absorbing layer can absorb more oil, increasing the oil absorption efficiency. The oil-blocking rubber plate is made of rubber and has soft properties. When in contact with the oil-absorbing layer, the oil-blocking rubber plate can squeeze the oil-absorbing layer, expelling the oil. On the other hand, the soft oil-blocking rubber plate can avoid causing significant scratches to the oil-absorbing layer, thus improving the service life of the oil-absorbing layer while expelling the oil.

[0021] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0022] like Figures 1 to 2As shown, the present invention preferably provides a roller scraping and oil collecting device, which includes a support assembly 10, a roller assembly 20, and an oil scraping assembly 30. The support assembly 10 includes a support 11; the roller assembly 20 includes an oil-absorbing roller 21 and an oil-absorbing layer 22. The oil-absorbing roller 21 is connected to the support 11 and can rotate on an axis parallel to the horizontal direction. The oil-absorbing layer 22 is wrapped around the outer peripheral wall of the oil-absorbing roller 21; the oil scraping assembly 30 includes a guide plate 31, an oil-blocking rubber plate 32, and an oil collecting groove 33. The oil collecting groove 33 is disposed in the radial direction of the oil-absorbing roller 21. The guide plate 31 is disposed on the side of the oil collecting groove 33 close to the oil-absorbing roller 21, and the guide plate 31 has a support surface that slopes downward along the oil-absorbing roller 21 toward the oil collecting groove 33. The oil-blocking rubber plate 32 is disposed in contact with the support surface, and the oil-blocking rubber plate 32 has an oil-guiding plane. One end of the oil-guiding plane protrudes from the support surface and abuts against the outer peripheral surface of the oil-absorbing layer 22, and the other end extends into the oil collecting groove 33.
[0023] Based on the above technical features, this utility model embodiment, through the design of the oil-absorbing roller 21 and the oil-absorbing layer 22, allows the oil-absorbing roller 21 to have a larger outer peripheral wall area compared to the traditional oil-scraping belt. Simultaneously, the oil-absorbing layer 22 is wrapped around the outer wall of the oil-absorbing roller 21, giving the oil-absorbing roller 21 a larger oil adsorption area when rotating on the surface of the oily wastewater, effectively improving the efficiency of oil adsorption in this device. The guide plate 31 is located on the side of the oil collection trough 33 near the oil-absorbing roller 21, and its supporting surface slopes downwards along the direction of the oil-absorbing roller 21 towards the oil collection trough 33, providing a stable installation environment for the oil-blocking rubber plate 32. When the oil-blocking rubber plate 32 is attached to the supporting surface, it can stably form a downwardly sloping flow channel, utilizing gravity... The force ensures that the oil can only flow towards the oil collection tank 33, and the scraped oil can smoothly flow into the oil collection tank 33 along the oil guide plane, avoiding oil residue on the oil-blocking rubber plate 32 and improving the working efficiency of oil adsorption and separation of this device. Finally, the oil-absorbing layer 22 can absorb more oil and improve the oil absorption efficiency. The oil-blocking rubber plate 32 is made of rubber material and has soft characteristics. When the oil-blocking rubber plate 32 comes into contact with the oil-absorbing layer, on the one hand, it can squeeze the oil-absorbing layer and squeeze the oil out of the oil-absorbing layer 22. On the other hand, the soft oil-blocking rubber plate 32 can avoid causing large scratches to the oil-absorbing layer 22, thereby improving the service life of the oil-absorbing layer 22 while squeezing out the oil.
[0024] As some embodiments of this utility model, such as Figures 1 to 2As shown, the oil-blocking rubber plate 32 is tightly fixed to the outer wall of the guide plate 31 by fasteners 34, and the oil-blocking rubber plate 32 and the guide plate 31 are detachably connected. By using fasteners 34 to tightly fix the oil-blocking rubber plate 32 to the outer wall of the guide plate 31, a tight contact is formed between the oil-blocking rubber plate 32 and the guide plate 31, effectively preventing oil leakage from the gap between them. Because the oil-blocking rubber plate 32 and the guide plate 31 are detachably connected, when the oil-blocking rubber plate 32 is damaged, aged, or requires cleaning, maintenance personnel can easily remove the oil-blocking rubber plate 32 from the guide plate 31 for replacement or repair without replacing the entire oil scraping assembly 30.
[0025] As some embodiments of this utility model, such as Figure 1 As shown, there are multiple fasteners 34, which are arranged at intervals along the length of the oil-blocking rubber plate 32. By arranging multiple fasteners 34 at intervals along the length of the oil-blocking rubber plate 32, the oil-blocking rubber plate 32 can be effectively fixed from multiple points. Compared with the arrangement of a single or a small number of fasteners 34, this layout can more evenly distribute the pressure acting on the oil-blocking rubber plate 32, avoiding deformation of the oil-blocking rubber plate 32 due to excessive local pressure.
[0026] As some embodiments of this utility model, such as Figure 1 As shown, the bottom outer wall of the oil collecting tank 33 has an oil outlet 331 for draining the oil from the tank. Since the outlet 331 is located at the lowest point of the tank, the oil will naturally flow towards it under its own gravity, eliminating the need for additional power equipment. This natural drainage method allows the oil to flow out of the tank quickly and smoothly, greatly improving the oil discharge efficiency and reducing the residence time of the oil within the tank, thereby enhancing the efficiency of the entire production process.
[0027] As some embodiments of this utility model, such as Figure 1 As shown, part of the oil-absorbing roller 21 is submerged in the oily wastewater, and the oil-absorbing layer 22 is made of oleophilic and hydrophobic polypropylene. Submerging part of the oil-absorbing roller 21 in the oily wastewater increases the contact area, allowing the oil-absorbing layer 22 to quickly contact the oil in the wastewater. The oleophilic and hydrophobic polypropylene material has a strong affinity for oil, quickly adsorbing it onto the material surface and into its internal pores, significantly shortening the oil absorption time of the oil-absorbing layer 22 and improving the treatment efficiency of the oily wastewater.
[0028] As some embodiments of this utility model, such as Figure 1As shown, the downward-sloping end of the guide plate 31 extends into and is fixed to the edge of the oil collection tank 33. The guide plate 31, with its inclined slope, provides a clear flow direction for the oil, allowing it to smoothly slide down the guide plate 31 into the oil collection tank 33. Compared to the absence of the guide plate 31 or an improperly designed guide plate 31, this design significantly shortens the oil collection path, reduces oil spillage and residue during the collection process, and thus significantly improves oil collection efficiency.
[0029] Furthermore, the oil-blocking rubber plate 32 is made of rubber and is used to block the oil absorbed by the oil-absorbing layer 22. When the oil-absorbing roller 21 rotates along the shaft 12, the oil-absorbing layer 22, which absorbs oil, passes through the oil-blocking rubber plate 32, and the oil is scraped off by the oil-blocking rubber plate 32. The rubber material has good elasticity and flexibility, and can closely adhere to the contact surface to form a reliable sealing barrier. When the oil-blocking rubber plate 32 is used to block the oil absorbed by the oil-absorbing layer 22, it prevents the oil from leaking out from these gaps.
[0030] As some embodiments of this utility model, such as Figures 1 to 2 As shown, it also includes a drive mechanism, which comprises a geared motor and a transmission component 13. The geared motor is located on one side of the oil suction drum 21 and connected to the oil suction drum 21 via the transmission component 13. Through the design of the geared motor, which is equipped with a speed regulation function, the rotational speed of the oil suction drum 21 can be precisely controlled, achieving a low rotational speed for the oil suction drum 21. This prevents the oil adsorbed by the oil suction layer 22 from being thrown out of the oil suction layer 22 when the oil suction drum 21 rotates, ensuring the stability of the oil adsorbed by the oil suction layer 22.
[0031] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the transmission component 13 includes a driving gear, a driven gear, and a chain. The driven gear is located between the support 11 and the oil suction drum 21, and is connected to the oil suction drum 21 via a rotating shaft 22. The output end of the geared motor is rotatably connected to the driving gear, which is connected to the driven gear via the chain, and is used to drive the oil suction drum 21 to rotate around a horizontally parallel axis. The transmission component 13 adopts a transmission method combining the driving gear, driven gear, and chain, which can effectively reduce energy loss during power transmission. The power output from the geared motor is transmitted to the chain via the driving gear, and then the chain precisely drives the driven gear to rotate, which in turn drives the oil suction drum 21 to rotate via the rotating shaft 12. This transmission method ensures the continuity and stability of power transmission, enabling the oil suction drum 21 to operate smoothly at a predetermined speed and torque, greatly improving the working efficiency of this device.
[0032] In summary, the oil collection device provided by this utility model, compared with the prior art, has the following advantages: Through the design of the oil-absorbing roller 21 and the oil-absorbing layer 22, the oil-absorbing roller 21 has a larger outer peripheral wall area compared to the traditional oil-scraping belt. Simultaneously, the oil-absorbing layer 22 is wrapped around the outer wall of the oil-absorbing roller 21, giving the oil-absorbing roller 21 a larger oil adsorption area when rotating on the surface of the oily wastewater, effectively improving the efficiency of oil adsorption. The guide plate 31 is located on the side of the oil collection trough 33 near the oil-absorbing roller 21, and its supporting surface is inclined downwards along the direction from the oil-absorbing roller 21 towards the oil collection trough 33, providing a stable installation environment for the oil-blocking rubber plate 32. When the oil-blocking rubber plate 32 is attached to the supporting surface, it can stably form a downward... The inclined flow channel, utilizing gravity, ensures that the oil flows only towards the oil collection tank 33. The scraped oil flows smoothly into the oil collection tank 33 along the oil guide plane, preventing oil residue on the oil-blocking rubber plate 32 and improving the oil adsorption and separation efficiency of the device. Finally, the oil-absorbing layer 22 can absorb more oil, improving the oil absorption efficiency. The oil-blocking rubber plate 32 is made of rubber and has soft properties. When the oil-blocking rubber plate 32 comes into contact with the oil-absorbing layer, it can squeeze the oil-absorbing layer and squeeze the oil out of the oil-absorbing layer 22. On the other hand, the soft oil-blocking rubber plate 32 can avoid causing significant scratches to the oil-absorbing layer 22, thereby improving the service life of the oil-absorbing layer 22 while squeezing out the oil.
[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
