Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically to an oil extraction filter. Background Technology

[0002] Petroleum is a mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar. After extraction, filtration devices are typically used to remove impurities. During the extraction process, petroleum contains sand and gravel impurities, which must be filtered out during processing.

[0003] According to an oil extraction filtration device with application number 202122772660.X, a filter belt is set up, and a first servo motor is started to drive the drive pulley to rotate, thereby driving the filter belt to rotate in a cycle. After the oil is poured in from the oil inlet funnel, the oil flows into the filter cylinder after being filtered by the filter belt. At the same time, the filter belt leaves large particles on its surface. The rotation of the filter belt causes the large particles to be scraped off by the scraper, thereby reducing the labor intensity of the workers.

[0004] However, the aforementioned oil extraction filtration equipment has certain shortcomings. When filtering oil, it is necessary to stop the filtration process to remove impurities, which will affect the overall filtration efficiency. Therefore, we propose an oil extraction filter. Utility Model Content

[0011] Preferably, the turntable is rotatably connected to the inner wall of the filter box.

[0012] This utility model provides an oil extraction filter with the following beneficial effects:

[0013] 1. This oil extraction filter, through the configuration of a servo motor, connecting rod, turntable, diversion groove, filter cartridges, mounting rod, base plate, rotating groove, through hole, connecting pipe, first solenoid valve, and collection box, allows oil to enter the filter box and fall into the diversion groove, then sequentially flow into several filter cartridges for filtration. During filtration, impurities in the oil remain in the filter cartridges. Then, by activating the servo motor, the connecting rod and turntable are driven to rotate, causing the filter cartridges to rotate sequentially to the top of the connecting pipe. After opening the first solenoid valve, the oil in the filter box enters the connecting pipe through the through hole, and the impurities in the filter cartridges are discharged into the collection box. This process is repeated to sequentially discharge the impurities in the oil into the collection box for treatment before discharge. No machine stoppage is required during filtration, resulting in higher filtration efficiency.

[0014] 2. This oil extraction filter, through the configuration of a first solenoid valve, a collection box, a filter screen, a water pump, a conduit, and a third solenoid valve, closes the first solenoid valve after oil and filtered impurities enter the collection box. By turning on the water pump, the oil that has entered the collection box can be discharged into the oil outlet pipe through the conduit for easy discharge. At the same time, the filter screen performs secondary filtration on the impurities entering the collection box, leaving the impurities on one side of the filter screen for easy subsequent discharge.

[0021] 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.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: an oil extraction filter, including a filter box 1, an oil inlet hopper 2 installed inside the top of the filter box 1, a servo motor 3 fixedly installed in the middle of the top of the filter box 1, a connecting rod 4 fixedly installed at the output end of the servo motor 3, a turntable 5 fixedly installed at one end of the connecting rod 4, the turntable 5 being rotatably connected to the inner wall of the filter box 1, a limiting seal ring 24 fixedly installed on the inner wall of the filter box 1 below the turntable 5, the turntable 5 cooperating with the limiting seal ring 24, a diversion groove 6 opened inside the top of the turntable 5, the oil inlet hopper 2 cooperating with the diversion groove 6, a plurality of filter cartridges 7 fixedly installed inside the turntable 5, an installation rod 8 fixedly installed in the middle of the bottom of the turntable 5, a base plate 9 fixedly installed at the bottom of the installation rod 8, and a rotating part opened at the bottom of the filter box 1. The trough 10 and the base plate 9 are rotatably connected to the rotating trough 10. Several through holes 11 are opened inside the base plate 9 and at the bottom of the filter cylinder 7. A connecting pipe 12 is installed inside the bottom of the filter box 1. A first solenoid valve 13 is installed inside the connecting pipe 12. A collection box 14 is installed at the bottom of the filter box 1. A drain pipe 15 is fixedly installed on one side of the bottom of the collection box 14. A second solenoid valve 16 is installed inside the drain pipe 15. When the first solenoid valve 13 is opened, the oil in the filter box 1 will enter the filter cylinder 7 from the outside and flow into the connecting pipe 12 through the through holes 11. When the oil enters the filter cylinder 7 from the outside, it will form a backwash, which will make the impurities filtered out in the filter cylinder 7 more thoroughly discharged into the collection box 14, thus avoiding the situation where the impurities in the oil clog the filter cylinder 7.

[0023] A filter screen 17 is fixedly installed in the middle of the inside of the collection box 14. Triangular blocks 18 are fixedly installed inside the collection box 14 on both sides of the filter screen 17. An oil outlet pipe 19 is fixedly installed on one side of the filter box 14. A fourth solenoid valve 23 is installed inside the oil outlet pipe 19. A water pump 20 is fixedly installed at the bottom of the other side of the collection box 14. The input end of the water pump 20 extends into the inside of the collection box 14. A conduit 21 is fixedly installed at the output end of the water pump 20. One end of the conduit 21 extends into the inside of the oil outlet pipe 19. A third solenoid valve 22 is installed inside the conduit 21. The two triangular blocks 18 are used to facilitate the discharge of oil and impurities through the drain pipe 15 and the water pump 20, respectively. When the oil is discharged through the drain pipe 15, a certain amount of oil will remain in the collection box 14, which facilitates the discharge of impurities.

[0024] In summary, in use, the oil to be filtered enters the filter box 1 through the inlet hopper 2. After entering the filter box 1, the oil flows into the inner side of the diversion groove 6, and then sequentially flows into several filter cartridges 7 for filtration. During filtration, impurities in the oil remain in the filter cartridges 7. Then, by turning on the servo motor 3, the connecting rod 4 and the turntable 5 are driven to rotate, causing the filter cartridges 7 to rotate sequentially to the top of the connecting pipe 12. After opening the first solenoid valve 13, the oil in the filter box 1 enters the connecting pipe through the through hole 11. After 12, the impurities in the filter cartridge 7 are discharged into the collection box 14. This process is repeated to sequentially discharge the impurities in the oil into the collection box 14 for processing and then discharge. When the oil and the filtered impurities enter the collection box 14, the first solenoid valve 13 is closed. By turning on the water pump 20, the oil that has entered the collection box 14 together can be discharged into the oil outlet pipe 19 through the conduit 21 for easy discharge. At the same time, the filter screen 17 performs secondary filtration on the impurities entering the collection box 14, leaving the impurities on one side of the filter screen 17 for easy subsequent discharge.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
