The design of the oil scraping mechanism is ingenious. The scraper blade abuts against the transmission belt, thoroughly scraping the oil adsorbed on the belt into the oil collection tank. The elastic element applies continuous tension to the oil collection tank through the through hole, and the rotating connection structure of the plug bolt ensures that the scraper blade is always in close contact with the transmission belt, avoiding the problem of incomplete oil scraping caused by transmission belt wear or vibration. The oil collected in the oil collection tank eventually flows into the oil collection tank below, completing the oil collection and separation. Compared with existing devices with unstable oil scraping effects, this overall structural design can achieve rapid separation of oil-water mixtures and precise oil collection through the adjustable depth of the transmission mechanism, the tight scraping of the scraper blade, and the flexible adjustment of each component, greatly improving the quality and efficiency of oil-water separation.

However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0017] It should be noted that all directional indicators in this utility model embodiment, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0018] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish items or operations described with the same technical terminology 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" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.

[0019] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings: like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of the belt-type oil-water separator in this embodiment. This embodiment provides a belt-type oil-water separator designed to solve the problem of low separation efficiency caused by loose transmission belts in traditional devices. The belt-type oil-water separator includes: a protective cover 1, a transmission mechanism 2, an oil scraping mechanism 3, and an oil collection tank 4; the height-adjustable transmission belt of the transmission mechanism 2 adjusts the tension caused by long-term use, and the elastic compensation structure of the oil scraping mechanism 3 ensures close contact between the transmission belt and the oil scraping components, thereby achieving efficient oil-water separation.

[0020] Please refer to the following: Figures 2-4 As shown, Figure 2 This is a three-dimensional structural diagram of the transmission mechanism in this embodiment; Figure 3 This is a three-dimensional structural diagram of the oil scraping mechanism in this embodiment; Figure 4 This is a side view of the oil scraping mechanism and the transmission belt in this embodiment. The transmission mechanism 2 includes a geared motor 21, a drive wheel 22, a driven wheel assembly 23, and a transmission belt 24. The driven wheel assembly 23, as the core component for adjusting the separation depth, includes a height adjustment plate 231 and a driven wheel 232. One end of the height adjustment plate 231 is installed on the outside of the protective cover 1, and its entire structure can slide freely and be fixed along the height direction of the protective cover 1. When the transmission belt 24 becomes loose and long after being immersed in the oil-water mixture for a long time, the distance between the drive wheel 22 and the driven wheel 232 can be changed by adjusting the position of the height adjustment plate 231 relative to the protective cover 1, so that the distance between the two can be adapted to the loosened and lengthened transmission belt 24, thereby solving the problem of the transmission belt 24 becoming longer due to being immersed in the oil-water mixture for too long. The geared motor 21 is fixed to the protective cover 1 by bolts and is located above the height adjustment plate 231. Its output shaft is connected to the drive wheel 22 to provide stable power for the transmission system. The drive wheel 22 is installed inside the protective cover 1 through bearings and rotates synchronously with the geared motor 21. The driven wheel 232 is installed at the other end of the height adjustment plate 231 through a rotating shaft, and is parallel to and height-matched with the drive wheel 22. The transmission belt 24 is made of high-strength polyester substrate with a uniform polyurethane coating on the surface. Polyurethane material has strong oleophilic and hydrophobic properties, which can efficiently adsorb the oil layer on the liquid surface. It also has the characteristics of wear resistance and chemical corrosion resistance, and is suitable for long-term immersion in industrial liquids such as oil-water mixtures. The transmission belt 24 is enclosed and wrapped around the drive wheel 22 and the driven wheel 232, and is driven by the drive wheel 22 to achieve cyclic rotation, continuously completing the operation cycle of immersion oil suction - lifting - oil scraping.

[0021] In addition, to ensure separation efficiency and solve the problem of incomplete oil scraping caused by loose transmission belt, the oil scraping mechanism 3 includes an oil collection groove 31, an oil scraper 32, a plug bolt 33, a fixing rod 34, and an elastic element 35. Plug bolts 33 are symmetrically fixed on opposite side walls of the protective cover 1. The two sides of the oil collection groove 31 are fitted onto the plug bolts 33 through shaft holes, allowing for flexible rotation around the axis of the plug bolts 33. The oil scraper 32 is made of wear-resistant rubber and is fixed to the end of the oil collection groove 31 near the transmission belt 24 by fixing bolts and nuts. Its top end is in close contact with the outer surface of the transmission belt 24. When the transmission belt 24 rotates, the oil scraper 32 can completely scrape off the oil layer adsorbed on its surface, ensuring that all the oil layer enters the oil collection groove 31. The oil collection groove 31 is made of stainless steel and bent into shape. A through hole 311 is opened on the bottom wall of the end away from the transmission belt 24, which is used to prevent the transmission belt 24 from loosening after long-term operation. The tension between the scraper blade 32 and the transmission belt 24 can be flexibly adjusted to ensure that the scraper blade is always in contact with the transmission belt. The fixing rod 34 is a stainless steel round rod, which is fixed to the inner wall of the protective cover 1 by welding. It is located on the oil collection groove 31 above the through hole 311 and is used to fix the elastic element 35. The elastic element 35 is a tension spring. One end of it is hung on the fixing rod 34 by a hook, and the other end is hung on the through hole 311. This elastic structure is the core of solving the problem of transmission belt loosening. When the transmission belt 24 becomes longer and looser due to long-term use, resulting in a gap between it and the scraper blade 32, the tension of the elastic element 35 will pull the end of the oil collection groove 31 near the through hole 311 to rotate around the plug bolt 33 towards the side closer to the transmission belt 24, so that the scraper blade 32 is always tightly attached to the surface of the transmission belt 24. The gap can be automatically compensated without manual intervention, which completely solves the problem of reduced separation efficiency caused by transmission belt loosening in traditional devices. The oil collection tank 4 has a rectangular structure and is placed below the end of the oil collection trough 31 away from the transmission belt 24. Its top opening faces the oil discharge end of the oil collection trough 31 and is used to collect all the oil discharged from the oil collection trough 31.

[0022] Furthermore, the height adjustment plate 231 has two collinear waist-shaped adjustment grooves 2311 along the height direction, and each adjustment groove 2311 is equipped with an adjustment bolt 2312. During adjustment, the adjustment bolt 2312 is loosened, and the height adjustment plate 231 can slide freely up and down along the adjustment groove 2311. After adjusting to the target height, that is, after the transmission belt 24 reaches the required immersion depth, the adjustment bolt 2312 is tightened so that its end presses against the outer wall of the protective cover 1, thereby fixing the height adjustment plate 231. This adjustment method is simple to operate and can be completed by a single person, and can accurately adjust the tension of the transmission belt 24.

[0023] Furthermore, the included angle 321 formed by the portion of the scraper blade 32 facing the drive belt 24 near the drive pulley 22 is designed to be greater than or equal to 90 degrees. This angle design allows the contact point between the scraper blade 32 and the drive belt 24 to form an "obtuse angle cutting" effect, which can efficiently peel off the oil layer and guide the oil to flow smoothly into the oil collection groove 31 along the surface of the scraper blade 32, avoiding oil splashing or residue. Tests have shown that this improves the oil scraping efficiency of the device.

[0024] Please refer to the following: Figures 5-6 As shown, Figure 5 This is a three-dimensional structural diagram of the driven wheel assembly in this embodiment; Figure 6 This is a cross-sectional schematic diagram of the driven wheel assembly in this embodiment. The driven wheel assembly 23 also includes a U-shaped transition plate 233, a retaining spring 234, a rotating shaft 235, and a copper sleeve 236. The U-shaped transition plate 233 is formed by bending steel plate and is fixed to the end of the height adjustment plate 231 away from the driving wheel 22 by bolts. The rotating shaft 235 is a stainless steel shaft, and a retaining spring 234 and a copper sleeve 236 are spaced apart at both ends. The opposite side walls of the U-shaped transition plate 233 are respectively embedded between the spaced retaining spring 234 and the copper sleeve 236. The driven wheel 232 is disposed on the rotating shaft 235. The copper sleeve 236 is made of wear-resistant brass and its inner diameter is compatible with the shaft 235. The U-shaped transition plate 233 has shaft holes on its opposite side walls. The copper sleeves 236 at both ends of the shaft 235 are respectively embedded in the shaft holes, and both side walls are restricted between the retaining spring 234 and the copper sleeve 236. That is, the retaining spring 234 is engaged in the annular groove of the shaft 235 to prevent the shaft 235 from moving axially. The copper sleeve 236 can reduce the coefficient of friction between the shaft 235 and the U-shaped transition plate 233, making the driven wheel 232 rotate more smoothly and reducing the running resistance and wear of the transmission belt 24.

[0025] Please refer to the following: Figure 7 As shown, Figure 7 This is a three-dimensional structural diagram of the oil collection tank in this embodiment. A vertical partition 41 is welded inside the oil collection tank 4, with a height of 2 / 3 of the tank's depth, dividing its internal space into two oil collection chambers 42. A gap is left between the bottom of the partition 41 and the bottom of the oil collection tank 4, forming a connecting channel. An arc-shaped drain pipe 421 is connected to the front of the left oil collection chamber 42. The drain pipe 421 can be connected to a flexible hose to guide the separated oil into a recovery tank. A drain pipe 422 is connected to the bottom of the right oil collection chamber 42. An adjusting nut 423 is screwed to the top of the drain pipe 422. This adjusting nut 423 can be rotated clockwise or counterclockwise to adjust the overall height between the drain pipe 422 and the adjusting nut 423, thereby enabling more precise oil-water separation.

[0026] Furthermore, the inner diameter of the adjusting nut 423 is adapted to the outer diameter of the drain pipe 422. By rotating the adjusting nut 423, its height on the drain pipe 422 can be changed. The oil discharged from the oil collection tank 31 will be mixed with a small amount of water. After entering the left oil collection chamber 42, the oil will float on the top due to its lower density, while the water will flow into the right oil collection chamber 42 through the gap at the bottom of the partition 41. The operator can control the drainage height of the drain pipe 422 by adjusting the nut 423 to ensure that only water is discharged from the drain pipe 422, while the oil remains in the left oil collection chamber 42 and is recovered through the oil drain pipe 421, realizing secondary separation of oil and water, thereby improving the oil separation efficiency.

[0027] Please refer to the following: Figure 8 As shown, Figure 8 This is a three-dimensional structural diagram of the protective cover in this embodiment. The protective cover 1 includes a protective shell 11 and a mounting assembly 12. The protective shell 11 is made of high-strength plastic material and has an overall cover structure. It is detachably connected to the mounting assembly 12 through buckles. After being placed on the mounting assembly 12, it can effectively protect the internal components and prevent external debris or liquid splashes from interfering with the operation of the equipment. One end of the height adjustment plate 231 is slidably mounted on the outer wall of the mounting assembly 12. Its installation position is consistent with the height direction of the mounting assembly 12, so that the height adjustment plate 231 can slide stably along the outer wall of the mounting assembly 12, thereby accurately adjusting the position of the driven wheel 232. The geared motor 21 is fastened to the upper part of the mounting assembly 12 by bolts, and is located directly above the height adjustment plate 231. This layout ensures the stability of power transmission and makes the equipment structure more compact, reducing the overall space occupied.

[0028] Furthermore, the mounting assembly 12 includes a motor mounting plate 121, at least two corner brackets 122, and multiple bolts 123. The motor mounting plate 121 is made of metal sheet and is bent into an L-shaped structure, with a first wall 1211 and a second wall 1212 that are perpendicular to each other. The first wall 1211 is mainly used to mount the geared motor 21 and the height adjustment plate 231, while the second wall 1212 serves as a bottom support and fixation. A circular connection port 1213 is provided in the middle of the first wall 1211. The size of the connection port 1213 is adapted to the output shaft of the geared motor 21. The geared motor 21 is fixedly mounted at the connection port 1213 through a flange structure to ensure that the output shaft can pass smoothly through the connection port 1213 and connect with the drive wheel 22. Directly below the connection port 1213, a long strip guide groove 1214 is provided along the height direction of the first wall 1211. The width of the guide groove 1214 is slightly larger than the thickness of the height adjustment plate 231. At the junction of the first wall 1211 and the second wall 1212, a notch 1215 with the same width as the guide groove 1214 is provided. The bottom of the guide groove 1214 extends to the notch 1215 and is completely connected to it, forming a complete sliding channel. One end of the height adjustment plate 231 passes through the notch 1215 and extends into the guide groove 1214, forming a sliding connection with the first wall 1211. The guide groove 1214 can accurately guide the sliding direction of the height adjustment plate 231, preventing it from deviating during adjustment. At least two corner brackets 122 are made of metal and are symmetrically distributed on both sides of the notch 1215. The two right-angled sides of each corner bracket 122 are fastened to the first wall 1211 and the second wall 1212 by multiple bolts 123. Through the reinforcement of the corner brackets 122, the structural strength and stability of the motor mounting plate 121 can be significantly improved, preventing it from deforming due to stress during long-term use.

[0029] For further details, please review. Figure 3 and Figure 4 The oil scraping mechanism 3 also includes a transition plate 36 and a limiting bolt 37. The transition plate 36 is a thick steel plate, fixed between the oil collection trough 31 and the motor mounting plate 121. The plug bolt 33 passes through the transition plate 36 and the side wall of the oil collection trough 31 in sequence, making the rotation of the oil collection trough 31 more stable. The limiting bolt 37 is an adjusting bolt used to fix the oil scraping mechanism 3 on the motor mounting plate 121 and passes through the transition plate 36 and is located below the oil collection trough 31. When the elastic element 35 pulls the oil collection trough 31 to rotate upward around the plug bolt 33, the end of the oil collection trough 31 near the oil scraper 32 will press downward. When the oil collection trough 31 rotates to a certain angle, the limiting bolt 37 will block the oil collection trough from continuing to rotate, which can prevent the end of the oil collection trough 31 near the oil scraper 32 from being pressed down excessively, thereby limiting the lowest position of the rotation of the oil collection trough 31, and preventing the elastic element 35 from pulling too much, causing the oil scraper 32 and the transmission belt 24 to be excessively squeezed, thereby avoiding the accelerated wear of the transmission belt 24.

[0030] In summary, transmission belts are prone to lengthening due to prolonged use and immersion in liquid, preventing direct contact between the transmission belt and the scraper. This embodiment addresses the issue of the belt-type oil-water separator by employing a sliding design of the height adjustment plate to prevent the transmission belt from lengthening due to prolonged immersion in the oil-water mixture, thus allowing for adjustment of the belt's tension during operation. Furthermore, the automatic compensation function of the elastic element ensures that the scraper and transmission belt maintain close contact at all times, significantly improving the separation efficiency of the oil-water mixture.
