A high-efficiency oil filtration device with convenient filter element replacement

Abstract

This utility model discloses a high-efficiency oil filtration device for convenient filter element replacement, including a mounting plate. Two limiting frames are fixedly connected to the bottom surface of the mounting plate. A filter element body is located inside the mounting plate. A snap-fit ​​groove and two positioning grooves are formed on the upper surface of the mounting plate, and these positioning grooves communicate with the snap-fit ​​groove. This device disengages the filter element body by rotating the locking cap, releasing the elastic force using a spring, and causing the locking and positioning plate to slide back to its original position along the sliding rod within the sliding hole. This allows for quick disassembly of the filter element body. A sealing sleeve seals the gap between the filter element body and the mounting plate, effectively preventing oil leakage. Simultaneously, the cooperation of the snap-fit ​​groove, positioning groove, and positioning ring ensures accurate positioning of the filter element body during installation, thereby achieving quick filter element replacement, precise positioning, and efficient sealing, significantly improving the ease of maintenance of the oil filtration device.

Description

Technical Field

[0001] This utility model relates to the field of oil pressing technology, and in particular to a high-efficiency oil filtration device with convenient filter element replacement. Background Technology

[0002] Traditional oil pressing emphasizes craftsmanship, which relies on accumulated experience. Each step of the traditional wooden oil press process is meticulous and has its own key points, such as the temperature, pressure, and time. The complex process of traditional oil pressing has not disappeared over time; instead, it has undergone continuous improvement and refinement, embodying the wisdom of generations of folk artisans and undergoing innovation.

[0003] However, the filter elements of traditional oil filtration devices are usually fixed by bolts or flanges. When replacing them, a large number of fasteners need to be disassembled, which is cumbersome, time-consuming and increases maintenance costs. To address these issues, we propose a high-efficiency oil filtration device with convenient filter element replacement. Utility Model Content

Two limiting frames are fixedly connected to the bottom surface of the mounting plate. A filter element body is located inside the mounting plate. A snap-fit ​​groove is formed on the upper surface of the mounting plate. Two positioning grooves are formed on the upper surface of the mounting plate, and the positioning grooves communicate with the snap-fit ​​grooves. A positioning hole is formed on the inner bottom wall of each positioning groove. A threaded rod is formed inside the positioning hole. The top end of each threaded rod penetrates the filter element body and extends above it. A locking cap is threadedly connected to the outer surface of the top end of each threaded rod. A locking positioning plate is fixedly connected to the bottom end of each threaded rod. A spring is fixedly connected to the upper surface of each locking positioning plate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4In this utility model, a high-efficiency oil filtration device for convenient filter element replacement includes a mounting plate 1. Two limiting frames 2 are fixedly connected to the bottom surface of the mounting plate 1. A filter element body 3 is provided inside the mounting plate 1. A snap-fit ​​groove 14 is opened on the upper surface of the mounting plate 1. Two positioning grooves 16 are opened on the upper surface of the mounting plate 1, and the positioning grooves 16 are connected to the snap-fit ​​grooves 14. A positioning hole 5 is opened on the inner bottom wall of each positioning groove 16. A threaded rod 6 is provided inside the positioning hole 5. The top end of each threaded rod 6 passes through the filter element body 3 and extends to the top of the filter element body 3. A locking cap 7 is threadedly connected to the outer surface of the top end of each threaded rod 6. A locking positioning plate 8 is fixedly connected to the bottom end of each threaded rod 6. A spring spring 11 is fixedly connected to the upper surface of each locking positioning plate 8. The top end of each spring spring 11 is fixedly connected to the bottom surface of the mounting plate 1.

[0021] A sealing gasket 4 is fitted on the outer surface of the filter element body 3. A sealing groove 15 is opened on the inner side wall of the snap-fit ​​groove 14, and the sealing groove 15 is adapted to the sealing gasket 4. The gap between the filter element body 3 and the mounting plate 1 is sealed by the sealing sleeve 12 to effectively prevent oil leakage. Two sliding holes 9 are opened on the upper surface of each locking positioning plate 8. A sliding rod 10 is slidably connected inside each sliding hole 9. The top end of each sliding rod 10 is fixedly connected to the bottom surface of the mounting plate 1, and the bottom end of each sliding rod 10 is fixedly connected to the inner side wall of the limiting frame 2. The elastic spring 11 releases the elastic force, which drives the locking positioning plate 8 to slide and reset along the sliding rod 10 in the sliding hole 9, realizing the quick disassembly of the filter element body 3. A sealing sleeve 12 is fixedly connected to the bottom surface of the mounting plate 1, and the inner ring of the sealing sleeve 12 is in contact with the outer surface of the filter element body 3. The sealing sleeve 12 is used to seal the filter element body 3.

[0022] A positioning collar 13 is fitted on the outer surface of the filter element body 3. The two locking positioning plates 8 are fixedly connected to the outer surface of the positioning collar 13 on their sides. The positioning collar 13 can be used to position the filter element body 3. Each threaded rod 6 is located in the inner ring of the elastic spring 11. The elastic spring 11 is a strong spring, which can increase the elastic force of the elastic spring 11. The elastic force of the elastic spring 11 can be used to fix the filter element body 3 and increase the stability of the filter element body 3.

[0023] The working principle of this utility model is as follows: When replacing the filter element body 3, the locking cap 7 is rotated and disengaged from the threaded rod 6. As the locking cap 7 loosens, the spring spring 11 releases its elastic force, causing the locking positioning plate 8 to return to its initial position. By moving the locking positioning plate 8, it can slide up and down along the sliding rod 10 within the sliding hole 9, and then the filter element body 3 can be removed from the mounting plate 1, thus achieving quick disassembly of the filter element body 3. The sealing sleeve 12 can seal the gap between the filter element body 3 and the mounting plate 1 to prevent oil leakage. The engagement of the snap-fit ​​groove 14 and the positioning groove 16 ensures accurate positioning and secure installation of the filter element body 3, thereby achieving quick replacement, precise positioning, and efficient sealing of the filter element, improving the maintenance convenience and operational reliability of the oil filtration device.
