Description

Technical Field

[0002] As a marine centrifugal separation device, the oil separator adopts a stacked conical disk micro-gap flow channel and a high-speed centrifugal force field. It achieves efficient separation of impurity particles and water by the difference in specific gravity between oil and water solids. The purified oil phase is output through centripetal motion, and an integrated automatic slag discharge system meets the needs of continuous operation.

[0003] The existing patent announcement number CN215609628U discloses an oil separator with purification and recovery functions. It achieves pre-treatment filtration of turbid crude oil by setting a filter device at the feed end of the oil separator, which improves the oil separation effect of the main part of the oil separator. However, due to the large amount of impurities in the turbid oil, it can quickly cover and clog the surface of the filter screen, and then manual cleaning is required before the filtration can continue. Such frequent cleaning has a great impact on the overall oil separation efficiency. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4 This embodiment provides an oil separator with purification and recovery functions, including an oil separator body 1. A drive chamber is fixed to the bottom of the oil separator body 1. The drive chamber includes a base shell 2. The oil separator body 1 is fixed to the top surface of the base shell 2. A motor 3 is fixed to the side of the top surface of the base shell 2 away from the oil separator body 1. The output shaft of the motor 3 is rotatably connected to the top plate of the base shell 2 and extends through the top plate of the base shell 2 to the inside of the base shell 2. A lower drive shaft 4 is also rotatably mounted on the top plate of the base shell 2. The lower end of the lower drive shaft 4 extends to the base. Inside the shell 2, the drive shaft 5 of the oil separator body is rotatably connected to the top plate of the base shell 2 and extends through the base shell 2 to the inside of the base shell 2. The output shaft of the motor 3, the lower transmission shaft 4, and the lower end of the drive shaft 5 of the oil separator body are all fixed with synchronous pulleys. The three synchronous pulleys are connected by a synchronous belt. The three synchronous pulleys are distributed in a triangle. When the oil is being separated, the motor 3 works, and through the synchronous pulleys and the synchronous belt, the lower transmission shaft 4 and the drive shaft 5 of the oil separator body rotate simultaneously, driving the oil separation work.

[0024] A filter is installed above the drive compartment. The filter includes a filter housing 6 and two filter screens 7 fixed to the inner wall of the filter housing 6 from top to bottom. The diameter of the upper filter screen 7 is larger than that of the lower filter screen 7. An inlet pipe 8 is fixed on the top plate of the filter housing 6. The bottom of the filter housing 6 is connected to the oil inlet of the oil separator body 1 through a guide pipe 16. The two filter screens 7 can pre-filter the oil entering the inner side of the oil separator body 1, removing large particles of impurities first, thereby improving the quality and efficiency of oil separation. The different diameters of the upper and lower filter screens 7 facilitate disassembly and assembly.

[0025] An upper drive shaft 9 is rotatably connected to the filter housing 6 via bearings at the axial position. The upper drive shaft 9 is rotatably connected to two filter screens 7. Two scraper strips 10 are fixed from top to bottom at the upper end of the upper drive shaft 9. The two scraper strips 10 abut against the top surfaces of the two filter screens 7 respectively. A first conical wheel 11 is fixed at both the lower and upper ends of the upper drive shaft 9. The two first conical wheels 11 are arranged opposite to each other. A support block 12 is fixed on the top surface of the base housing 2. A screw 13 is threadedly connected to the upper end of the support block 12 through a threaded hole. A second conical wheel 14 is rotatably installed at the end of the screw 13 near the first conical wheel 11. The conical surface of the second conical wheel 14 respectively matches the conical surface of the two first conical wheels 11. A knob 15 is fixed at the end of the screw 13 away from the second conical wheel 14.

[0026] When the cleaning time limit is reached, turn knob 15 to rotate screw 13, pushing the second conical wheel 14 to move closer to the first conical wheel 11, so that the conical surface of the first conical wheel 11 abuts against the conical surfaces of the two second conical wheels 14. Then, while the motor 3 drives the oil separation work, the lower transmission shaft 4 rotates to drive the first conical wheel 11 to rotate, and uses friction to drive the second conical wheel 14 to rotate. Then, the power is transmitted to the upper transmission shaft 9, so that the scraper 10 rotates to scrape the surface of the filter screen 7, so that the attached impurities are scraped off without covering the surface of the filter screen 7, ensuring the passability.

[0027] In summary, this invention designs an upper drive shaft 9-scraper 10 linkage cleaning system and a coaxial transmission mechanism. Power coupling is achieved through the upper drive shaft 9, lower drive shaft 4, and synchronous pulley set. During the operation of the oil separator, the scraper 10 on the surface of the filter screen 7 is synchronously driven to perform periodic cleaning, effectively removing attached impurities to maintain filter flow efficiency. The device uses a screw 13-conical wheel transmission assembly to form an adjustable clutch mechanism, which can selectively activate and deactivate the cleaning function according to the oil quality, avoiding ineffective wear. The entire system is entirely driven by the main unit, requiring no additional independent power unit. While ensuring filtration efficiency, it significantly reduces equipment energy consumption and maintenance costs, possessing the combined advantages of intelligent control and modular design.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
