Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, specifically relating to a filtration device adapted to an oil-water separator. Background Technology

[0002] An industrial oil-water separator is an industrial device used to treat oily wastewater. It is mainly used in petrochemical, metallurgical, machining, and food processing industries to achieve efficient separation of oil-water mixtures. Based on the principle of oil-water density difference and combined with physical separation technology, it completes purification through a multi-stage process including gravity separation, centrifugation, and oil skimming.

[0003] Oil tankers are typically equipped with oil-water separators, which involve multiple processes, one of which is filtering the tank wash water. During filtration, particulate matter in the wash water can easily clog the filter screen, hindering the filtration process. Therefore, oil-water separators are equipped with filtration devices to remove impurities from the incoming material. However, particulate matter in the material can still clog the filter screen, affecting the filtration operation. To address this issue, we propose a filtration device adapted for oil-water separators. Summary of the Invention

[0006] By employing the above-mentioned scheme, multiple filter housings with varying mesh sizes can be used in conjunction to improve the filtration effect on materials. Combined with motor one, the crushing shaft, and the crushing blades, it can crush large-volume solid materials, preventing accumulation and jamming. Simultaneously, motor two drives the fixed and movable shafts in conjunction with the cleaning brush to clean the filter housings, further preventing mesh blockage and ensuring smooth and orderly filtration operations.

[0022] By using multiple filter housings 8 with different mesh sizes, the filtration effect on materials can be improved. When used with motor 12, crushing shaft 13, and crushing blade 14, large-volume solid materials can be crushed, avoiding accumulation and jamming. At the same time, when used with motor 217 to drive fixed shaft 9 and movable shaft 10 in conjunction with cleaning brush 11, the filter housing 8 can be cleaned, further preventing mesh blockage and ensuring smooth and orderly filtration. By using assembly ring 15 and assembly bolt 16, the fixed cylinder 4 and movable cylinder 5 can be easily disassembled and cleaned. By using connecting plate 20 and connecting bolt 21, the cleaning brush 11 can be easily disassembled and installed.

[0023] A motor 12 is fixedly installed on the side of the movable cylinder 5. The output shaft of the motor 12 extends into the interior of the movable cylinder 5 and a crushing shaft 13 is fixedly installed thereon. Several crushing blades 14 are fixedly installed on the outer surface of the crushing shaft 13. The motor 12 drives the crushing shaft 13 to rotate, which in turn drives the crushing blades 14 to rotate. This allows for the crushing of large solid materials, effectively preventing large solid materials from accumulating inside the filter housing 8 and causing blockage.

[0024] Assembly rings 15 are fixedly installed on the outer surfaces of both the fixed cylinder 4 and the movable cylinder 5. Several assembly bolts 16 are threaded between the two assembly rings 15. By using the assembly rings 15 and the matching assembly bolts 16, the fixed cylinder 4 and the movable cylinder 5 can be easily assembled and cleaned.

[0025] Both ends of the movable shaft 10 are fixedly installed with cross sockets 18. Both ends of the fixed shaft 9 and the output shaft end of the motor 2 17 are provided with cross slots that cooperate with the cross sockets 18. By inserting the cross sockets 18 into the cross slots, a stable connection is achieved between the output shaft of the motor 2 17, the fixed shaft 9 and the movable shaft 10, so that the three can rotate stably and synchronously.

[0026] Several limiting plates 19 are fixedly installed on the outer surface of the filter housing 8, and several limiting slots are opened on the inner wall of the processing cylinder 1. The limiting plates 19 and the limiting slots are used together. By using the limiting plates 19 and the limiting slots together, the filter housing 8 can be limited and inserted, thus preventing the filter housing 8 from moving or shaking.

[0027] A connecting plate 20 is fixedly installed on the outer surface of the movable shaft 10. A connecting bolt 21 is threaded between the connecting plate 20 and the cleaning brush 11.

The connecting plate 20 and the connecting bolt 21 can be used to facilitate the assembly and disassembly of the cleaning brush 11. The alignment block 22 and the alignment hole can be used to achieve precise alignment between the cleaning brush 11 and the connecting plate 20.

[0028] During use, the material is injected into the fixed cylinder 4 through the inlet pipe 6 for filtration. The motor 12 starts and drives the crushing shaft 13 to rotate. The crushing shaft 13 drives the crushing blade 14 to rotate, thereby crushing the large solid materials in the material. Then the material enters the processing cylinder 1 and is filtered through multiple filter housings 8. The solid materials remain in the filter housings 8, and the liquid is discharged through the outlet pipe 7. At the same time, the motor 217 starts and uses the cross socket 18 to drive the movable shaft 10 and the fixed shaft 9 to rotate synchronously, thereby driving the cleaning brush 11 to rotate, so as to prevent the filter housings 8 from clogging. After the operation is completed, the assembly bolt 16 is unscrewed to unlock the fixed cylinder 4 and the movable cylinder 5, and then the fixed cylinder 4 is cleaned. The processing cylinder cover 2 is opened and removed, and the filter housings 8 and the movable shaft 10 are pulled out one by one. The connecting bolt 21 is unscrewed to unlock and disassemble the cleaning brush 11.
