Description

Technical Field

[0001] The utility model relates to the technical field of oil filter devices used in oil mining, and more specifically, to an oil filter device used in oil mining. Background Art

[0002] In the current oil production process, the oil filter device is an indispensable key equipment, which can effectively remove impurities in crude oil, ensure the quality of oil and the efficiency of subsequent processing. However, the existing filter device has a significant shortcoming in actual use. Since the filter shell needs to be replaced regularly after a long period of work to maintain the filtering effect, the existing equipment design does not fully take this into account. First of all, the existing filter device is often complex in structure, making the replacement process of the filter shell cumbersome and time-consuming. This design not only increases the labor intensity of on-site staff, but also reduces the convenience of equipment use to a certain extent.

[0003] Secondly, due to the inconvenience of replacing the filter shell of the existing equipment, it may be necessary to shut down for maintenance in actual operation, which not only prolongs the downtime of the equipment, reduces the extraction efficiency, but also may increase the maintenance cost. In addition, the complicated replacement process may also increase the risk of equipment damage, further affecting the stability and service life of the equipment. Therefore, how to improve the design of the existing oil filtration device so that it can replace the filter shell more conveniently and quickly has become an important research direction for improving the convenience of equipment use and improving oil extraction efficiency. Such improvements will help reduce maintenance costs and improve the continuous operation capability of the equipment, thereby better meeting the oil extraction industry's demand for efficient and stable equipment.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a petroleum filtering device for petroleum mining, which has the following beneficial effects:

[0017] 1. The design of the installation mechanism makes the installation process of the filter shell easier and faster. By installing the filter shell on the fixing seat and using the cooperation between the middle rod and the fixing sleeve, as well as the mechanism of the spring and the push rod, the filter shell can be easily positioned and fixed. This design reduces the labor intensity during installation and improves work efficiency. The compression and release of the spring enables the fixing sleeve to be stably sleeved on the middle rod, and the sliding connection of the push rod in the spiral groove ensures the precise alignment of the filter shell during the fixing process. Overall, this installation mechanism helps to improve the convenience of equipment use and reduce maintenance costs.

[0018] 2. The fixing mechanism ensures the stability and safety of the filter shell during the filtration process through the cooperation of the hexagonal sleeve and the limit sleeve. The sliding connection of the hexagonal sleeve and the fixing groove on the limit sleeve, as well as the design of the anti-slip groove, enable the filter shell to be firmly fixed on the equipment to prevent displacement caused by vibration or pressure. This fixing mechanism not only improves the filtration efficiency, but also extends the service life of the filter shell. The setting of the spring and the limit groove makes the fixing process more reliable and reduces the potential risks caused by the instability of the filter shell.

[0019] 3. The rotating mechanism uses the cooperation of the guide bar and the guide groove to provide a flexible rotation mechanism for the replacement of the filter shell. By rotating the hexagonal sleeve, the top rod can be driven to rotate along the spiral groove. This design makes the removal and installation of the filter shell more flexible and reduces the complexity of operation. The rotating mechanism not only improves the convenience of replacing the filter shell, but also makes the maintenance of the entire filter device easier. In addition, the precise cooperation of the guide bar and the guide groove ensures the smoothness of the rotation process, avoids equipment damage caused by improper operation, and thus improves the overall reliability and stability of the equipment.

[0030] In this embodiment, when the corresponding filter shell 4 needs to be installed, the filter shell 4 is first installed on the fixing seat 3, and then the fixing sleeve 6 is sleeved on the intermediate rod 5. At this time, the hexagonal sleeve 11 is pressed hard, so that the spring 15 is compressed by the downward force, and then the multiple push rods 8 are placed in the position of the limiting groove 14. Since the limiting groove 14 does not fit on the push rod 8, when the intermediate rod 5 is inserted into the fixing sleeve 6, the multiple push rods 8 will be stretched open, and then they can be easily inserted into the fixing sleeve 6. Then, the hexagonal sleeve 11 is released, and the hexagonal sleeve 11 can be driven to slide upward under the action of the spring 15, and then the fixing groove 13 is pressed on the multiple push rods 8, and the push rods 8 slide inward and press in the spiral groove 10, and then the guide strip 17 is slidably connected in the guide groove 18, and by rotating the hexagonal sleeve 11, the multiple push rods 8 can be driven to rotate along the spiral groove 10.

[0032] In summary, when the overall device is in use or running: when the corresponding filter shell 4 needs to be installed, the filter shell 4 is first installed on the fixing seat 3, and then the fixing sleeve 6 is sleeved on the intermediate rod 5. At this time, force is pressed on the hexagonal sleeve 11, so that the spring 15 is compressed by the downward force, and then the multiple push rods 8 are placed in the position of the limiting groove 14. Since the limiting groove 14 does not fit on the push rod 8, when the intermediate rod 5 is inserted into the fixing sleeve 6, the multiple push rods 8 will be spread apart, and then they can be easily inserted into the fixing sleeve 6. After that, the hexagonal sleeve 11 is loosened, and the hexagonal sleeve 11 can be driven to slide upward under the action of the spring 15, and then the fixing groove 13 is pressed against the multiple push rods 8, and the push rods 8 slide inward and press against the spiral groove 10, and then the guide bar 17 is slidably connected in the guide groove 18, and by rotating the hexagonal sleeve 11, the multiple push rods 8 can be driven to rotate along the spiral groove 10. At this time, the push rods 8 are in a fixed state, so the fixing sleeve 6 can be driven to rotate downward, and then the compression spring 7 is pressed on the filter shell 4, thereby completing the process of filtering the shell 4.

[0033] When filtering is required, petroleum is introduced through the feed pipe 2, then flows into the filter shell 4, then flows into the outer shell 1 after passing through the filter shell 4, and then discharged through the discharge shell, thereby completing the filtering of the petroleum.
