[0033] With the rapid development of the shipbuilding industry, especially the widespread application of precision shipbuilding and rapid shipbuilding technologies, the production efficiency and economic benefits of shipbuilding enterprises have significantly improved. However, the problem of waste oil disposal generated during shipbuilding has become increasingly prominent, becoming one of the key factors restricting the sustainable development of enterprises. The traditional waste oil disposal method usually involves selling the waste oil to recycling companies at a low price. This method not only wastes resources but also leads to economic losses for enterprises.

[0034] Among related technologies, waste oil filtration technology has many shortcomings, such as complex structure, cumbersome operation, and reliance on auxiliary equipment, resulting in low filtration efficiency and high maintenance costs. Furthermore, traditional devices typically require dedicated personnel or additional instruments to operate normally, increasing the company's human and material resources investment.

[0035] Therefore, such as Figures 1 to 3As shown, the waste oil filtration device proposed in this utility model includes a support 100, a filter barrel 200 installed on the support 100, and a filter structure disposed within the filter barrel 200. One end of the filter barrel 200 is provided with an inlet pipe 210 for inputting waste oil, and the other end of the filter barrel 200 is provided with an outlet pipe 220 located below the inlet pipe 210. Specifically, the filter structure has a vertical serpentine flow channel 310 and a filter component 320. The two ends of the vertical serpentine flow channel 310 are respectively connected to the inlet pipe 210 and the outlet pipe 220. The filter component 320 is disposed within the vertical serpentine flow channel 310 to filter the flowing waste oil. It should be noted that the filter barrel 200 is supported by a bracket 100, and a vertical serpentine flow channel 310 and a filter component 320 are set inside the filter barrel 200. This forces the waste oil to flow along a serpentine path, significantly extending the filtration path and time, thereby effectively improving filtration efficiency. The filter component 320 set inside the vertical serpentine flow channel 310 can fully filter the waste oil, ensuring the oil purification effect. The overall structure of the device is simple and compact, and the operation is convenient. Waste oil filtration can be completed without professional personnel. It effectively solves the problem of waste oil treatment in the shipbuilding process, realizes the efficient recycling and reuse of waste oil, meets environmental protection requirements, and creates considerable economic benefits for enterprises.

[0036] Refer to Figure 1 and Figure 3In some embodiments of this utility model, the vertical serpentine flow channel 310 includes a first filter chamber 311, a second filter chamber 312, and a third filter chamber 313 connected in sequence. The input plane of the second filter chamber 312 is lower than the inlet pipe 210, and the input plane of the third filter chamber 313 is lower than the input plane of the second filter chamber 312, so as to drive waste oil from the first filter chamber 311 into the second filter chamber 312 and the third filter chamber 313 in sequence. The input planes of the first filter chamber 311, the second filter chamber 312, and the third filter chamber 313 descend in a stepped manner, relying on gravity to flow naturally, forming a waste oil flow path driven by the height difference. This enables the device to achieve multi-stage filtration function in a limited space, with a compact structure and strong practicality. Furthermore, the middle sections of the first filter chamber 311, the second filter chamber 312, and the third filter chamber 313 each have a liquid-receiving groove 3101. The filter component 320 is installed in the liquid-receiving groove 3101. The bottom surface of the liquid-receiving groove 3101 has a hollow structure to allow waste oil to pass through after filtration, achieving precise positioning of the filtration area and efficient filtration. It is easy to understand that the hollow structure of the bottom surface of the liquid-receiving groove 3101 ensures that the filtered waste oil can pass smoothly while preventing the filter cotton 321 from shifting or deforming due to the impact of waste oil. This allows the filter cotton 321 to be stably maintained in the optimal filtration position, ensuring the stability of the filtration effect. It also facilitates the replacement and maintenance of the filter cotton 321, improving the practicality and maintainability of the device. Specifically, the filter component 320 includes multiple filter cottons 321, with each filter cotton 321 arranged in a one-to-one correspondence with a liquid-receiving groove 3101. To address this, the parallel use of multiple filter cottons 321 significantly increases the filtration area, allowing impurities in the waste oil to be more thoroughly intercepted, resulting in a more complete filtration effect and a significant improvement in filtration capacity. Simultaneously, this modular configuration of filter cottons 321 facilitates adjusting the number of filter cottons 321 or replacing damaged ones as needed, improving the flexibility and economy of the device, making it particularly suitable for treating waste oils with significant differences in oil quality. Furthermore, the liquid receiving tank 3101 has a concave structure, with the filter cottons 321 matching the shape of the tank and fitting snugly against its inner wall. This not only enhances the stability of the filter cottons 321, preventing displacement during waste oil flow, but also ensures that the waste oil is evenly distributed on the surface of the filter cottons 321, avoiding dead zones or incomplete filtration in certain areas. In addition, the concave structure increases the contact area between the waste oil and the filter cottons 321, further improving filtration efficiency, while also facilitating the smooth passage of waste oil through the perforated bottom surface into the next filtration chamber, ensuring the continuity and stability of the filtration process.

[0037] Refer to Figure 2In some embodiments of this utility model, the support 100 is provided with an arc groove 101, and the filter barrel 200 is installed in the arc groove 101, achieving stable installation and precise positioning of the filter barrel 200. It is understood that the design of the arc groove 101 perfectly matches the shape of the filter barrel 200, not only enhancing the stability of the device and preventing the filter barrel 200 from shaking or tilting during use, but also simplifying the installation process and improving assembly efficiency. Furthermore, in some embodiments of this utility model, by fixing anti-slip rubber 230 to the outer wall of the filter barrel 200 and forming a tight pressing fit with the groove wall of the arc groove 101, the friction between the filter barrel 200 and the support 100 is significantly enhanced, optimizing the anti-slip design. This anti-slip design effectively prevents the filter barrel 200 from accidentally sliding during waste oil flow impact or operation, improving the stability and safety of the device. Meanwhile, the anti-slip rubber 230 also has a certain cushioning effect, which can absorb some vibration and impact, protect the filter barrel 200 and the support 100 from damage, and extend the service life of the device. It is especially suitable for use in dynamic environments such as ships.

[0038] In addition, refer to Figure 1 and Figure 2 In some embodiments of this utility model, a lid 202 is rotatably mounted on the top of the filter barrel 200 to open and close the filter barrel 200, enabling rapid opening and closing of the filter barrel 200. This design not only facilitates the operator in adding waste oil or replacing the filter component 320 into the filter barrel 200, but also keeps the lid 202 closed during the filtration process, preventing waste oil splashing or odor diffusion, thus improving the working environment. The rotatable lid 202 design also facilitates observation of the working status inside the filter barrel 200, making operation more intuitive and convenient, and improving the ease of use and safety of the device. Specifically, the filter barrel 200 includes a body 201, and the body 201 and the lid 202 are connected by a hinge 203. The hinge 203 connection enables flexible opening and closing and stable fixation of the lid 202. This connection method has a simple and reliable structure, is easy to maintain and replace, and reduces manufacturing costs, making the device more economical and practical, especially suitable for application scenarios that require frequent opening and closing of the filter barrel 200.

[0039] Optionally, refer to Figure 1 The outlet pipe 220 is equipped with a switch valve 221, which enables control over the discharge of filtered waste oil. Operators can open or close the valve at any time as needed to control the collection and recycling of filtered waste oil.

[0040] In summary, the usage process of this product is as follows:

[0041] 1. Preparations before use: Place this device next to the waste oil storage tank that needs to be filtered, attach one end of the spare hose to the outer surface of the inlet pipe 210 of the filter tank 200 and lock it with a clamp, and connect the other end of the hose to the hand-cranked oil pump for startup.

[0042] 2. Usage Process: Open the switch valve 221 of the filter tank 200, rotate the oil pump, and continuously rotate the oil pump to allow the waste oil in the waste oil storage tank to flow through the hose and inlet onto the filter cotton 321 of the first filter chamber 311 inside the filter tank 200. After being filtered by the filter cotton 321, the first-stage filtered waste oil drips into the bottom of the filter tank 200 through multiple small holes on the bottom surface of the liquid receiving tank 3101. As it continues to drip... As the first stage of filtered oil accumulates at the bottom, when the height of the stored first stage of filtered oil exceeds the inlet line of the second filter chamber 312, the first stage of filtered oil flows smoothly into the second filter chamber 312. Subsequently, the flow into the third filter chamber 313 follows the same process as the flow into the second filter chamber 312. In addition, after three stages of filtration, the waste oil is very clear and free of impurities. The waste oil filtration process is completed, and the final filtered crystal clear secondary oil drips into the oil receiving tray through the outlet pipe 220 and the switch valve 221.

[0043] In some applications, the filter chambers of the vertical serpentine flow channel 310 are formed by multiple staggered baffles 3102, and the liquid receiving tank 3101 is composed of a concave bent plate installed inside the filter barrel 200.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
