To ensure the subsequent assembly quality and performance of these parts, it is necessary to perform rapid and effective oil stain removal treatment on their surfaces.
[0003] However, existing oil removal technologies have many shortcomings: First, manual wiping and static soaking are inefficient, difficult to clean complex structural parts of components, and labor-intensive; second, they are poorly adaptable to handling parts of different sizes, unable to achieve batch, efficient cleaning operations, and have low applicability; third, existing cleaning equipment generally lacks effective oil separation and discharge mechanisms, making it difficult to discharge waste oil generated during the cleaning process in a timely manner, easily causing secondary pollution; finally, traditional methods have limited ability to remove oil stains from the surface of components, especially for highly adhesive oil stains, where the removal effect is unsatisfactory and the processing time is long.
[0004] Therefore, there is an urgent need to develop a new type of rotary decontamination device that can efficiently remove oil stains from the surface of mechanical parts, has good oil stain separation and discharge functions, can adapt to the processing needs of parts of different specifications, is easy to operate, and has a stable decontamination effect, so as to meet the technical requirements of the modern machinery manufacturing industry for the rapid removal of oil stains from the surface of parts.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] Please see Figure 1-5 This utility model provides a technical solution: a rotary oil stain removal device for mechanical parts, comprising:
[0040] Base 1, motor mounting base 2 is fixedly connected to the top of base 1, and drive motor 3 is mounted on the top of motor mounting base 2;
[0041] The outer shell 4 has an intermediate guide plate 5 fixedly connected to the inner wall of the middle part of the outer shell 4;
[0042] The drain pipe 7 is fixedly connected to the middle of the outer casing 4, and the drain pipe 7 is connected to the inside of the outer casing 4;
[0043] The inner housing 8 is located inside the outer housing 4. The bottom of the inner housing 8 is fixedly connected to the motor shaft of the drive motor 3. The middle part of the inner housing 8 is fixedly connected to the central shaft 9. The inner housing 8 is provided with a first drainage mechanism and a second drainage mechanism.
[0044] The protective top ring 10 is fixed to the top of the outer shell 4 by bolts. The top of the protective top ring 10 is connected to the protective cover 11 by hinge. A cleaning injection pipe 17 is fixedly connected to the protective cover 11.
[0045] Several sets of component partitions 14 are connected to the central shaft 9;
[0046] The first and second drain mechanisms are adapted to drain the oil from the inner casing 8.
[0047] Specifically, the double-layer structure design of the outer shell 4 and the inner shell 8 ensures the sealing performance of the device. The inner diameter of the protective top ring 10 is greater than the outer diameter of the inner shell 8. The protective top ring 10 and the protective cover 11 are connected by bolts and hinges, which not only ensures the safety protection of the device during operation, but also facilitates the loading and unloading of parts and the maintenance of the equipment by the operators.
[0048] Specifically, by setting up the cleaning injection pipe 17, the cleaning fluid or clean water can be injected into the inner housing 8 even when the protective cover 11 is closed, thus improving the utilization efficiency of the cleaning medium. This application uses the drive motor 3 to rotate the inner housing 8, causing a strong scouring effect on the parts in the cleaning fluid, greatly improving cleaning efficiency. The centrifugal force generated by the rotation can effectively remove stubborn oil stains from the surface and crevices of the parts, resulting in a significantly better cleaning quality than traditional static immersion methods.
[0049] Reference manual attached Figure 2-3 The intermediate guide plate 5 has a ring-shaped structure, with its height decreasing regularly from the center to the edge. A ring-shaped anti-overflow edge 6 is fixedly connected to the top of the intermediate guide plate 5. Specifically, the geometric shape of the intermediate guide plate 5, with its regularly decreasing height from the center to the edge, effectively collects the oily liquid ejected from the inner shell 8 during rotation. When the inner shell 8 rotates at high speed, the ejected liquid, under centrifugal force, flows orderly along the inclined surface of the intermediate guide plate 5 towards the edge, eventually converging into the drain pipe 7 for unified discharge. The ring-shaped anti-overflow edge 6 plays a crucial role in liquid control, preventing the collected oily liquid from overflowing the intermediate guide plate 5 during flow, ensuring that all ejected liquid is effectively collected and guided to the drainage system.
[0050] Reference manual attached Figure 2 The inner bottom surface of the inner shell 8 is a frustum-shaped structure. Specifically, the inclined surface of the frustum-shaped structure can guide the oil spilled from the surface of the parts to collect downwards along a specific path, avoiding the disorderly accumulation of oil at the bottom of the device. This structural design can also reduce the residence time of oil inside the device, improve the timeliness and thoroughness of oil discharge, prevent the re-adhesion of separated oil, and ensure the durability and reliability of the decontamination effect.
[0051] Specifically, when the inner shell 8 rotates at high speed under the drive of the drive motor 3, the centrifugal force gradient generated by the frustum-shaped inner bottom surface allows oil stains of different densities to naturally stratify according to their physical properties, with heavy oil stains converging to the outside and light oil stains relatively concentrated on the inside.
[0052] Reference manual attached Figure 2 and instruction manual attached Figure 4-5 The first drainage mechanism includes:
[0053] Several sets of lower drainage tanks 12 are arranged in a regular ring array and are opened through the lower end of the inner shell 8;
[0054] The lower drain tank 12 is set at an angle.
[0055] Specifically, the annular array arrangement of multiple lower drain tanks 12 ensures the uniform distribution of drain ports in the circumferential direction. The inclined structural design combines gravity discharge and centrifugal discharge, allowing heavy oil deposits at the bottom of the inner shell 8 to flow naturally into the lower drain tanks 12 under gravity and be accelerated outward under centrifugal force. This design not only improves the discharge efficiency of heavy oil but also reduces resistance and retention during the discharge process, ensuring the cleanliness of the device's interior during continuous operation.
[0056] Reference manual attached Figure 2 and instruction manual attached Figure 4-5 The second drainage mechanism includes:
[0057] Several sets of upper drain holes 13 are distributed and connected on the inner shell 8;
[0058] Among them, the upper drain hole 13 has a horizontal frustum-shaped structure.
[0059] Specifically, the inner diameter of the opening at the end of the upper drain hole 13 near the inner side of the inner shell 8 is larger than the inner diameter of the opening at the end of the upper drain hole 13 near the outer side of the inner shell 8. This transverse frustum geometry can generate an outward guiding force during the rotation of the inner shell 8, making it easier for the light oil floating on the upper layer to enter the upper drain hole 13. The distribution of multiple upper drain holes 13 increases the discharge channels for light oil and improves the parallel processing capability of the drain.
[0060] Specifically, the dual-layer, graded drainage design of the first and second drainage mechanisms enables effective treatment of oil stains of different properties, improving the thoroughness of oil stain removal.
[0061] Reference manual attached Figure 4-5The central shaft 9 has several sets of slots 15 arranged in a regular circular array. Each slot 15 has an "L"-shaped structure that matches one end of a part partition 14. One end of the part partition 14 is inserted into the slot 15, and the other end is connected to the inner wall of the inner housing 8. Specifically, the regular circular array of slots 15 allows the part partition 14 to be installed and adjusted at multiple angles in the circumferential direction as needed, accommodating the placement requirements of parts of different shapes and sizes. The L-shaped fit not only ensures a firm connection between the part partition 14 and the central shaft 9 but also provides excellent resistance to centrifugal force, maintaining a stable connection even at high speeds. The design of one end of the part partition 14 being inserted into the slot 15 and the other end connected to the inner wall of the inner housing 8 forms a stable triangular support structure, greatly enhancing the overall rigidity and stability of the partition system. This design allows operators to quickly adjust the number and position of partitions according to the specific characteristics of the parts to be processed, achieving the goal of processing multiple specifications of parts with one machine, significantly improving the versatility and efficiency of the equipment, and reducing the equipment investment costs for enterprises.
[0062] Reference manual attached Figure 1-2 The outer casing 4 has through-holes 16 on both the front and rear sides at its lower end. Specifically, these through-holes 16 allow heat to be expelled from the device promptly through natural convection and forced ventilation, ensuring that the motor and other critical components operate within a suitable temperature range and extending the equipment's lifespan. The symmetrical arrangement on the front and rear sides creates excellent airflow channels, enhancing the uniformity and continuity of heat dissipation. Furthermore, it allows maintenance personnel to inspect, clean, and perform necessary maintenance on internal critical components without completely disassembling the device, significantly reducing the complexity and time cost of maintenance.
[0063] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
