Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, specifically to a petrochemical residue oil filtration device. Background Technology

[0002] In oil refineries, residual oil is often used to produce products such as petroleum coke, residual lubricating oil, and petroleum asphalt, or as a feedstock for cracking. Due to mechanical impurities such as ferric naphthenate and ferrous sulfide in residual oil, the presence of these impurities can lead to scaling, foaming, corrosion, abrasion, and reduced catalyst activity. Therefore, in the production process of residual oil, it is necessary to filter the residual oil before further processing.

[0003] Existing filtration devices suffer from a simplistic filtration structure, making the filter cartridges prone to clogging by impurities in the residual oil. These impurities gradually adhere to the inner wall of the filter cartridge, leading to decreased filtration efficiency. This not only necessitates frequent cleaning of the filter cartridges, increasing the workload for workers, but also disrupts production continuity due to downtime for cleaning, further reducing efficiency. Secondly, the existing equipment design fails to effectively address the issues of impurity adhesion and clogging. It typically relies solely on the filter cartridge for filtration without auxiliary structures to prevent impurity adhesion, making it difficult to fundamentally prevent filter cartridge mesh clogging and resulting in high maintenance costs.

[0015] Compared with the prior art, this utility model provides a petrochemical residue oil filtration device, which has the following beneficial effects: 1. This petrochemical residue oil filtration device, through its filtration mechanism, allows operators to simply start a servo motor to drive the filter cylinder and agitator blades to rotate simultaneously. The agitator blades and filter cylinder rotate in opposite directions. The rotation of the filter cylinder uses centrifugal force to agitate the internal oil outwards, separating impurities from the oil. Meanwhile, the agitator blades, rotating in the opposite direction to the filter cylinder, generate turbulence that drives away impurities that reach the inner wall of the filter cylinder, preventing them from adhering to the inner wall and gradually clogging the external mesh. This extends the working time of the filter cylinder, reduces the time interval for cleaning, and lowers the workload for operators. Furthermore, after the oil is drained, the centrifugal action of the filter cylinder ensures no oil residue remains inside the impurities, guaranteeing high oil utilization.

[0016] 2. This petrochemical residue oil filtration device uses a locking mechanism to position the sealing cover plate by engaging the sliding plate within the mounting bracket. This ensures the airtight connection between the sealing cover plate and the top of the device body during filter cartridge use. Simultaneously, operators can easily release the sealing cover plate by pressing the lever downwards and then pulling the pull ring outwards, facilitating filter cartridge replacement and cleaning of accumulated impurities inside the filter cartridge.

[0024] The filter assembly 11 includes a filter cartridge 1101, which is disposed inside the main body 3 of the device. A sealing cover 1102 is rotatably connected to the top of the filter cartridge 1101 and is snapped into the top of the main body 3 of the device.

The sleeve 1205 is fixedly connected to the bottom of the filter cartridge 1101. The transmission assembly 13 includes a drive gear ring 1301, which is fixedly connected to the outer ring of the drive shaft 1203. A differential gear 1302 meshes with the outer ring of the drive gear ring 1301. A fixed shaft 1303 is rotatably connected to the inner ring of the differential gear 1302. The fixed shaft 1303 is fixedly connected to the bottom of the main body 3 of the device. The outer ring of the differential gear 1302 meshes with a transmission gear 1304. A rotating shaft 1305 is fixedly connected to the top of the transmission gear 1304. The rotating shaft 1305 is rotatably connected to the bottom of the main body 3 of the device. A second transmission gear 1306 is fixedly connected to the top of the rotating shaft 1305. The reinforcing assembly 14 includes a retaining shaft 1401, which is rotatably connected to the bottom of a fixed shaft 1303. A retaining ring 1402 is fixedly connected to the bottom of the retaining shaft 1401. The retaining ring 1402 is sleeved on the outer ring of the drive shaft 1203.

The rotating rail 1504 is rotatably connected to the inner ring of the outer ring of the rotating ring 1503.

The lower inner ring of the rotating ring 1503 is fixedly connected to the transmission gear ring 1505, which meshes with the outer ring of the transmission gear 1306.

[0025] Furthermore, the operator only needs to start the servo motor 1201 to drive the filter cartridge 1101 and the stirring blade 1501 to rotate simultaneously. The stirring blade 1501 and the filter cartridge 1101 rotate in opposite directions. The rotation of the filter cartridge 1101 agitates the oil inside through centrifugal force, separating the impurities inside the oil. The stirring blade 1501, through the turbulence generated by rotating in the opposite direction to the filter cartridge 1101, drives away the impurities that reach the inner wall of the filter cartridge 1101 by centrifugal motion, preventing the impurities from adhering to the inner wall of the filter cartridge 1101. This prevents the impurities from gradually clogging the external mesh of the filter cartridge 1101 with use, extending the working time of the filter cartridge 1101, reducing the time interval for cleaning the filter cartridge 1101, and reducing the workload of the operator. Example 2

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 Furthermore, based on Embodiment 1, the locking mechanism 2 includes a locking component 21 and a positioning component 22. The locking component 21 is disposed on the top of the device body 3, and the positioning component 22 is disposed on the outer ring of the device body 3.

[0027] Locking component 21 includes a fixing frame 2101, which is fixedly connected to the four corners of the top of the main body 3 of the device. A sliding plate 2102 is slidably connected inside the fixing frame 2101. A limiting slider 2103 is fixedly connected inside the fixing frame 2101 and slidably connected inside the sliding plate 2102. A retaining seat 2104 is sleeved on the inner side of the sliding plate 2102 and is fixedly connected to the top of the sealing cover plate 1102. A pull ring 2105 is fixedly connected to the top of the sliding plate 2102. Positioning component 22 includes... The device includes a fixed cylinder 2201, which is fixedly connected to the outer ring of the main body 3 at the position corresponding to the slide plate 2102. A slide cylinder 2202 is slidably connected inside the fixed cylinder 2201. A compression spring 2203 is fixedly connected to the bottom of the slide cylinder 2202. A locking rod 2204 is fixedly connected to the top of the slide cylinder 2202. A telescopic slide rod 2205 is fixedly connected to the bottom of the slide cylinder 2202. The telescopic slide rod 2205 is slidably connected inside the bottom of the fixed cylinder 2201. A pull rod 2206 is fixedly connected to the bottom of the telescopic slide rod 2205.

[0028] Furthermore: the sliding plate 2102 is engaged in the seat 2104 to position the sealing cover plate 1102, ensuring the sealing between the sealing cover plate 1102 and the top of the device body 3 when the filter cartridge 1101 is in use. At the same time, the operator only needs to press the pull rod 2206 downward and then pull the pull ring 2105 outward to release the positioning of the sealing cover plate 1102, which makes it convenient for the operator to replace the filter cartridge 1101 and clean the impurities accumulated inside the filter cartridge 1101.

[0029] If drive shaft 1203 rotates clockwise: Then, the prism rod 1204 rotates clockwise → the sleeve 1205 rotates clockwise → the filter cartridge 1101 rotates clockwise; The drive gear ring 1301 rotates clockwise → the differential gear 1302 rotates counterclockwise → the transmission gear 1304 rotates clockwise → the rotating shaft 1305 rotates clockwise → the transmission gear 1306 rotates clockwise → the transmission gear ring 1505 rotates counterclockwise → the rotating ring 1503 rotates counterclockwise → the subsequent rotating ring 1503 drives the stirring blade 1501 to rotate counterclockwise through the connecting rod 1502.

[0030] In actual operation, when this device is used, first connect the oil supply pipe to the top of the liquid inlet 1103, and then connect the oil outlet pipe to the bottom of the liquid outlet 31. Then start the servo motor 1201. The servo motor 1201 drives the sleeve 1205 to rotate through the drive shaft 1203 and the rib 1204. The rotation of the sleeve 1205 drives the filter cartridge 1101 to rotate. At the same time as the servo motor 1201 starts, the differential gear 1302 is driven to rotate through the drive shaft 1203 and the drive gear ring 1301. The rotation of the differential gear 1302 drives the rotating shaft 1305 to rotate through the fixed shaft 1303. The rotation of the rotating shaft 1305 drives the rotating ring 1503 to rotate through the transmission gear ring 1505. The rotation of the rotating ring 1503 drives the stirring blade 1501 to rotate through the connecting rod 1502. At this time, the stirring blade 1501 rotates in the opposite direction to the filter cartridge 1101. Then, the oil is fed into the filter cartridge 1101 through the oil supply pipe and the liquid inlet 1103 until it enters the main body 3 of the device. The oil entering the filter cartridge 1101 is centrifuged by the rotation of the filter cartridge 1101, which drives the internal oil and impurities to separate outward synchronously. The oil passes through the filter cartridge 1101 and enters the main body 3 of the device and is discharged through the liquid outlet 31, while the impurities are intercepted by the filter cartridge 1101 and adhere to the inner wall of the filter cartridge 1101. At the same time, the stirring blade 1501 rotates in the opposite direction in the main body 3 of the device to form a turbulence for the oil. This turbulence is opposite to the rotation of the filter cartridge 1101 and drives the impurities in the filter cartridge 1101 away from the inner wall of the filter cartridge 1101. The combination of the two ensures that the filter cartridge 1101 will not be blocked by impurities during use, and ensures the normal use of the filter cartridge 1101. At this time, the oil filtration process is completed. When it is necessary to disassemble the filter cartridge 1101 to clean the impurities inside, first turn off the servo motor 1201. Then, the operator presses the pull rod 2206 downwards. The pull rod 2206 moves downwards, which in turn moves the slide cylinder 2202 downwards via the telescopic slide rod 2205. The downward movement of the slide cylinder 2202 moves the locking rod 2204 downwards. The locking rod 2204 moves downwards and retracts into the fixed cylinder 2201, disengaging from the slide plate 2102. Then, the operator pulls the pull ring 2105 outwards. 05. Move the slide plate 2102 outward. The slide plate 2102 moves outward and disconnects from the card holder 2104, releasing the positioning of the sealing cover plate 1102. Then, the operator can directly hold the liquid inlet 1103 upward. The liquid inlet 1103 moves upward and drives the filter cartridge 1101 upward through the sealing cover plate 1102. The filter cartridge 1101 moves upward and disengages from the main body 3 of the device. At this time, the disassembly of the filter cartridge 1101 is completed. Then, the operator can directly clean the impurities inside the filter cartridge 1101.
