[0003] Oil-water separators are commonly used waste recovery devices in kitchens, hotels, and recycling centers. Their main function is to separate oil-water mixtures into oil and water. Various types of oil-water separators exist, but their primary principle relies on the buoyancy of oil to separate the oil floating on the surface of the mixture. For example, some use scrapers to remove oil, but this method is inefficient, has unstable transmission mechanisms, and is susceptible to problems with unsuitable materials, resulting in mediocre separation performance and a short lifespan.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0031] Please see Figure 1-2 This embodiment provides an oil-water separation device for separating an oil-water mixture into oil and water. The oil-water separation device includes:

[0032] Base 1, base 1 forms a first cavity 11, the first cavity is used to hold an oil-water mixture;

[0033] Separation baffle 2 is disposed above the first cavity 11 of the base, and at least part of the bottom of the separation baffle 2 is disposed inside the first cavity 11. The side of the separation baffle 2 facing away from the top surface of the first cavity 11 has a second cavity 21.

[0034] The oil-water separation mechanism 3 includes a drive motor 31, a drive shaft 32, a drum 33, and a scraper 34. The drive motor 31 is fixed on the separation baffle 2. The output end of the drive motor 31 is connected to the drive shaft 32. The drive shaft 32 passes through the drum 33 along the axial direction and is fixedly connected to the drum 33. The separation baffle 2 has an opening. The area below the opening is the first cavity region 11, and the area above the opening is the second cavity region 21. The drum 33 is positioned between the first cavity 11 and the second cavity 21 at the opening. The scraper 34 has a first side and a second side that are arranged opposite to each other. The first side of the scraper 34 is arranged in contact with the generatrix of the drum 33, and the second side of the scraper 34 is inclined downward toward the second cavity 21.

[0035] The outer wall of the roller 33 is made of stainless steel. The drive motor 31 drives the roller 33 to rotate via the drive shaft 32. The roller 33 is used to lift the oil floating on the surface of the oil-water mixture placed in the first cavity 11 and scrape it into the second cavity 21 by the scraper 34.

[0036] With the above structure, during use, the operator only needs to pour the oil-water mixture from the top into the first cavity 11 of the base 1, so that the first cavity 11 is filled with the oil-water mixture. By means of physical properties, the oil and water will separate. The oil with lower density floats on the upper layer of water. As more oil-water mixture is gradually added, the liquid level of the upper layer of oil rises until the oil surface touches the bottom of the roller 33 in the oil-water separation mechanism 3. At this time, the oil-water separation mechanism 3 is driven to run, and the roller 33 rotates. By means of the viscosity of the oil on the stainless steel surface of the roller 33 and the inertia of rotation, some of the oil is rotated from the bottom position of the roller 33 to the top position of the roller 33. When it rotates to the position of the scraper 34, since the scraper 34 is in close contact with the roller 33, the oil on the roller 33 near the contact position is scraped off by the scraper 34 and guided to the second cavity 21 of the separation baffle 2 on the second side of the scraper 34. It continues to run, thus realizing the collection of oil into the second cavity 21.

[0037] In the above-described process, the oil in the oil-water mixture is collected by fully utilizing the attraction and inertia of the material. Since the stainless steel roller 33 has difficulty carrying water, only the separated water remains in the first cavity 11 of the base 1, achieving complete oil-water separation. Specifically, in this embodiment, since the stainless steel roller 33 is similar to or the same material as the base 1 and the separation baffle 2, it is inexpensive, easy to manufacture, and has low processing difficulty. Furthermore, compared to existing rollers 33 made of acrylic, it has better wear resistance and a longer service life. In this embodiment, the drive motor 31 is directly connected to the roller 33 via a drive shaft 32 for output, instead of using couplings or other methods as in existing systems. Therefore, the rotation control of the roller 33 can achieve better coaxiality, more stable rotation, and a more compact design, saving more space.

[0038] Furthermore, the first side of the scraper 34 that contacts the roller 33 is made of nylon. Specifically, considering the wear-prone nature of nylon, the main body of the scraper 34 can be a stainless steel plate connected to the separation baffle 2 by welding or fasteners, while the second end of the scraper 34 is connected to a nylon plate of matching size by a slot or fastener, making the nylon plate easy to replace and easy to maintain later.

[0039] Furthermore, the stainless steel outer wall of roller 33 is set as a polished surface. The polished stainless steel material has higher strength and longer service life than traditional acrylic plastic material, and has a stronger adhesion to oil compared to other rough metal materials without polishing.

[0040] Furthermore, the axial length of the roller 33 matches the width of the second cavity 21. Specifically, in this embodiment, as... Figure 1 As shown, the separation baffle 2 encloses and forms a second cavity 21 space that is equivalent to the axial length of the roller 33. It has an enclosing wall, which can maximize the oil level in the second cavity 21 and increase the pressure at the bottom of the oil, thereby maximizing the oil accumulation and discharge speed.

[0041] Furthermore, the second cavity 21 has an oil outlet 22 at its bottom, which is connected to a waste oil collection tank. Specifically, the oil outlet 22 at the bottom of the second cavity 21 is located at a corner of the second cavity 21. Therefore, when oil accumulates to a certain level in the second cavity 21, the oil outlet 22 at the corner can more effectively drain all the oil from the second cavity 21. In another embodiment, the second cavity 21 can be configured as a slope inclined towards the oil outlet 22, further enhancing the efficiency of oil drainage.

[0042] Furthermore, the oil-water separation device also includes a screen 4, which is positioned above the base 1 with its bottom facing the first chamber 11. The screen 4 is used for the first preliminary screening of the oil-water mixture. The operator pours the oil-water mixture into the screen 4 from the top, allowing the screen 4 to filter out some of the residue, preventing it from floating to the roller 33 and causing wear.
