Description

Technical Field

[0001] This utility model belongs to the field of oil depot equipment technology, and more specifically, it relates to a multi-stage filtration device for oil depot pipelines. Background Technology

[0002] With the rapid development of the petrochemical industry, the safe and efficient operation of oil depot pipeline transportation systems is crucial. During storage and transportation, oil inevitably becomes contaminated with solid impurities such as rust, silt, and welding slag, as well as pollutants like gum and asphalt produced by oxidation and polymerization. These impurities not only affect the quality of the oil and reduce its performance, but can also cause pipeline blockages, valve wear, and instrument malfunctions, seriously threatening the normal operation of oil depot equipment and increasing maintenance costs and safety hazards. Furthermore, strict requirements are placed on the cleanliness of oil during oil trade and quality inspection. Therefore, developing efficient and reliable oil depot pipeline filtration devices is key to ensuring oil quality, extending equipment lifespan, and ensuring the safe and stable operation of oil depots. Multi-stage oil depot pipeline filtration devices, through a rationally designed multi-stage filtration structure, can specifically remove impurities of different particle sizes and properties, meeting the diverse filtration needs of oil depot pipeline systems.

[0003] Based on the above, the development of efficient and reliable oil depot pipeline filtration devices is urgently needed. Existing single-stage filtration systems are insufficient to meet diverse filtration requirements, while multi-stage filtration devices for oil depot pipelines, through rationally designed multi-stage filtration structures, can specifically remove impurities of different particle sizes and properties. This not only ensures oil quality but also reduces the risk of equipment failure, which is of great significance for extending equipment lifespan and ensuring the safe and stable operation of oil depots.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a multi-stage filtration device for oil depot pipelines, including a waste tank 1, a main pipe 2, a filter screen 4, a transmission pipe 5, a propulsion screw 6, and a switch panel 7; the filter screen 4 is fastened to the central circular hole of the main pipe 2, and a set of flange connecting pipes 3 are fastened to the upper and lower sides of the central circular pipe of the main pipe 2; a set of rotary control knobs 701 are provided on the upper part of the switch panel 7, and the switch panel 7 and the rotary control knobs 701 are rotatably connected to the circular holes on the two circular pipes of the main pipe 2; the transmission pipe 5 is fastened to one side of the two circular pipes of the main pipe 2, and the propulsion screw 6 is rotatably connected inside the transmission pipe 5; one side of the waste tank 1 is fastened to the end of the circular pipe on one side of the transmission pipe 5 through a circular pipe.

[0026] The main pipe 2 has threads on both the top and bottom sides, and the flange connecting pipe 3 is fastened to the top and bottom sides of the main pipe 2 by threads. The flange connecting pipe 3 has six sets of threaded round holes on the outside. The threaded connection between the main pipe 2 and the flange connecting pipe 3 can be quickly disassembled and assembled, which is convenient for equipment installation and maintenance. The six sets of threaded round holes on the outside of the flange connecting pipe 3 can accurately connect to the oil depot pipeline system, enhance the connection stability, and ensure the sealing and safety during the oil transportation process.

[0027] The filter screen 4 has filter holes at the top and a set of guide blocks at the bottom. The filter screen 4 is connected to the main pipe 2 by threads. The filter holes of the filter screen 4 are of different sizes to filter different impurities. The lower guide blocks can guide the filtered impurities smoothly into the transmission pipe 5.

[0028] The main pipe 2 has a set of threads on each of its left and right sides, and the transmission pipe 5 is fastened to the left and right sides of the main pipe 2 by the threads. The threaded connection design between the main pipe 2 and the transmission pipe 5 facilitates quick assembly and disassembly, and makes it convenient for equipment inspection and maintenance. The tight threaded connection can ensure the sealing of the connection, prevent oil leakage, and enhance the structural stability, ensuring the long-term reliable operation of the filtration system.

[0029] The transmission pipe 5 has a set of T-shaped annular grooves on one side, and the propulsion screw 6 has a set of T-shaped annular blocks on the outside. The outside of the propulsion screw 6 is rotatably connected to the T-shaped annular grooves on one side of the transmission pipe 5. The T-shaped annular grooves of the transmission pipe 5 and the T-shaped annular blocks of the propulsion screw 6 cooperate to limit the radial displacement of the screw and ensure stable rotation to push impurities. This rotatable connection method not only ensures the transmission of pushing power, but also facilitates disassembly and maintenance, effectively maintaining the efficient operation of the impurity conveying system.

[0030] The waste tank 1 is equipped with a set of square buttons on its outer side. These square buttons on the outer side of the waste tank 1 are easy for operators to grasp quickly, enabling convenient disassembly and installation of the waste tank and facilitating the cleaning of internal impurities. At the same time, the button design allows for precise positioning, ensuring a secure connection between the waste tank and the transmission pipe and preventing oil leakage.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In this invention, the device is connected to the oil depot pipeline system through six sets of threaded round holes on the outside of the flange connecting pipe 3. Oil flows into the main pipe 2 through the flange connecting pipe 3. Under the action of the filter screen 4, impurities of different particle sizes are intercepted. The guide block at the bottom of the filter screen 4 guides the filtered oil to continue its transport, improving the purification effect. Impurities produced during filtration are deposited inside the main pipe 2. Rotating the rotary control knob 701 drives the switch disk 7, opening the channel between the main pipe 2 and the transmission pipe 5. The flowing gasoline propels the spiral 6, whose outer T-shaped ring block rotates along the T-shaped ring groove on one side of the transmission pipe 5, pushing the impurities to the waste tank 1 for storage, preventing impurity accumulation from affecting filtration efficiency. When maintenance or cleaning is required, rotating the square button block on the outside of the waste tank 1 disassembles it. Simultaneously, the flange connecting pipe 3 and the transmission pipe 5 are disassembled using the threaded connection, facilitating the inspection and replacement of components such as the filter screen 4. The sealing design of the threaded connection reduces the risk of oil leakage, ensuring the stable operation of the multi-stage filtration device in the oil depot pipeline.
