Description

Technical Field

[0001] The invention relates to the technical field of rapeseed oil filtration, in particular to rapeseed oil production filtration equipment with an impurity removal function. Background Art

[0002] The production process of rapeseed oil generally includes pretreatment, pressing, extraction and refining. The clean rapeseed is sent to the press for mechanical pressing. During the pressing process, the rapeseed will be squeezed to release the oil in it. Usually a screw press or a hydraulic press is used. The rapeseed oil after pressing or extraction may contain impurities, plant residues or solvent residues. Large particles of impurities and solid particles are filtered out through mechanical filters or screens. Finer filters or filter media, such as pulp filter paper, activated carbon or ceramic filters, are used to remove smaller suspended particles, waxes, gums, etc. However, the residue is fine and easy to clog the filter, which reduces the filtering effect. These impurities may affect the appearance and quality of rapeseed oil. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a rapeseed oil production filtering device with impurity removal function comprises an oil storage cylinder, four filtering mechanisms, a filter residue chamber and a separation mechanism, wherein the filter residue chamber is arranged outside the oil storage cylinder, each of the filtering mechanisms comprises an oil inlet pipe, a filter, a siphon head and a vertical pipe, the oil inlet pipe is installed on one side of the filter, the other side of the filter is connected to the oil storage cylinder through a pipeline, the siphon head is located in the oil inlet pipe, the vertical pipe is located outside the oil inlet pipe, the siphon head is connected to the vertical pipe through a pipeline, and all the One end of the vertical pipe is connected to the filter residue chamber, one side of the filter residue chamber is provided with a residue outlet, the separation mechanism is arranged on one side of the residue outlet, and an oil extraction pipe is connected to the lower part of the oil storage cylinder, the extracted rapeseed oil is transported to the oil inlet pipe through the pipeline, and at the same time, the control system extracts oil from the oil storage cylinder through the oil extraction pipe, so that the gas in the oil storage cylinder is reduced, forcing the rapeseed oil to pass through the filter element and enter the oil storage cylinder, thereby filtering the rapeseed oil, and the filter residue in the rapeseed oil is retained by the filter element, and the filter residue finally enters the filter residue chamber through the vertical pipe, and the filter residue is further processed by the separation mechanism.

[0005] Furthermore, the four filtering mechanisms are evenly distributed in a circle around the oil storage cylinder, a rotating ring is rotatably arranged in each filter, a sealing ring is arranged between the filter and the two sides of the rotating ring, a filter element is arranged in the middle of the rotating ring, a worm gear groove is opened on the outer contour of the rotating ring, a rotating shaft is rotatably installed on the filter, a worm is arranged in the middle of the rotating shaft, the worm is located inside the filter, the worm is meshed with the worm gear groove, and the sealing ring plays a sealing role between the rotating ring and the filter to prevent rapeseed oil from leaking into the filter.

[0006] Furthermore, four right-angle support plates are arranged on the filter residue chamber, each of the right-angle support plates rotatably supports two adjacent rotating shafts, bevel gears are arranged at both ends of each rotating shaft, and the adjacent bevel gears are meshed with each other.

Since the position of the scraper is fixed, the filter element in the rotating ring moves in accordance with the scraper, and the filter residue trapped on the filter element is scraped off by the scraper and squeezed into the siphon head. Since the top of the long slide groove of the sliding core is connected with the outside world, and since the top height of the sliding core is higher than the oil inlet pipe, the rapeseed oil will not overflow from the top of the vertical pipe through the sliding core under the state of atmospheric pressure balance. The rapeseed oil keeps flowing to prevent the scraped filter residue from diffusing in the opposite direction. After the filter residue is scraped into the siphon head, it is retained inside, and the surface of the scraped filter element restores the filtering function, thereby minimizing the clogging effect of the filter residue on the filter element.

After a period of filtration, as the filter residue in the siphon head accumulates more and more, the control system controls the electric push cylinder to push the sliding core downward and starts closing timing until the bottom of the sliding core extends out of the sleeve, and the oil in the sliding core flows into the filter residue chamber. The rapeseed oil in the oil inlet pipe flows into the sliding core under the siphon effect, and the rapeseed oil carries the filter residue through the through pipe into the sliding core, and finally flows out from the bottom of the sliding core and enters the filter residue chamber. After the closing timing ends, the control system lifts the sliding core upward and resets it through the electric push cylinder. At this time, the filter residue accumulated in the siphon head has been completely discharged into the filter residue chamber. In order not to waste the residual rapeseed oil in the filter residue, it is necessary to further separate the filter residue and rapeseed oil through a separation mechanism.

The lower part of the oil storage cylinder 1 is connected with an oil extraction pipe 29. The squeezed rapeseed oil is transported to the oil inlet pipe 2 through the pipeline. At the same time, the control system extracts oil from the oil storage cylinder 1 through the oil extraction pipe 29, so that the gas in the oil storage cylinder 1 is reduced, forcing the rapeseed oil to pass through the filter element 4 and enter the oil storage cylinder 1, so as to realize the filtration of the rapeseed oil. The residue in the rapeseed oil is retained by the filter element 4, and the residue finally enters the filter residue chamber 10 through the vertical pipe 19, and the separation mechanism is used to further process the residue.

[0027] Four filtering mechanisms are evenly distributed around the oil storage cylinder 1 in a circular shape, a rotating ring 6 is rotatably arranged in each filter 3, a sealing ring 5 is arranged between the filter 3 and the two sides of the rotating ring 6, a filter element 4 is arranged in the middle of the rotating ring 6, a worm gear groove is opened on the outer contour of the rotating ring 6, a rotating shaft 8 is rotatably installed on the filter 3, a worm 7 is arranged in the middle of the rotating shaft 8, the worm 7 is located inside the filter 3, the worm 7 is meshed with the worm gear groove, four right-angle support plates 12 are arranged on the filter residue chamber 10, each right-angle support plate 12 rotatably supports two adjacent rotating shafts 8, bevel gears 9 are arranged at both ends of each rotating shaft 8, and the adjacent bevel gears 9 are meshed with each other, a driven sprocket 15 is arranged on a rotating shaft 8, a first servo motor 13 is arranged on the upper end of the oil storage cylinder 1, and a second servo motor 13 is arranged on the upper end of the oil storage cylinder 1. A driving sprocket is installed on the motor shaft of a servo motor 13. The first servo motor 13 is connected to the control system through a circuit. A chain 14 is connected between the driving sprocket and the driven sprocket 15. The sealing ring 5 plays a sealing role between the rotating ring 6 and the filter 3 to prevent rapeseed oil from leaking into the filter 3. During the filtration of rapeseed oil, the control system enables the first servo motor 13 to be powered on, and the first servo motor 13 drives the driving sprocket to rotate. The driving sprocket drives the driven sprocket 15 to rotate through the chain 14. The driven sprocket 15 drives the rotating shaft 8 to rotate. The rotating shaft 8 rotates the worm 7. The worm 7 drives the rotating ring 6 to rotate through the worm wheel groove. When a rotating shaft 8 rotates, the rotating ring 6 in each filter 3 is rotated through the connection transmission between the bevel gears 9.

[0028] A through hole is provided on each oil inlet pipe 2, a through-tube 18 is provided in the through-hole, the through-tube 18 is connected with the siphon head 17, a scraper 16 is provided on one side of the siphon head 17, the scraper 16 is in contact with the filter element 4, the through-tube 18 is connected with the middle part of the vertical pipe 19, a sliding core 21 is slidably installed inside the vertical pipe 19, the sliding core 21 is hollow inside, a long straight groove is provided on one side of the sliding core 21 facing the through-tube 18, the long straight groove is connected with the internal hollow part, an electric push cylinder 22 is provided on the top of the vertical pipe 19, the piston rod of the electric push cylinder 22 is connected with the sliding core 21, and the vertical pipe 1 9 is connected with the filter residue chamber 10 through a sleeve 20. The bottom of the filter residue chamber 10 is inclined, and the residue outlet 23 is located at the lower end of the bottom of the filter residue chamber 10. Since the position of the scraper 16 is fixed, the filter element 4 in the rotating ring 6 moves in close contact with the scraper 16, and the filter residue trapped on the filter element 4 is scraped off by the scraper 16 and squeezed into the siphon head 17. Since the top of the long chute of the sliding core 21 is connected to the outside world, and because the top height of the sliding core 21 is higher than the oil inlet pipe 2, the rapeseed oil will not overflow from the top of the vertical pipe 19 through the sliding core 21 under the state of atmospheric pressure balance, and the rapeseed oil will not overflow from the top of the vertical pipe 19 through the sliding core 21. The seed oil keeps flowing to prevent the scraped filter residue from dispersing in the opposite direction. The filter residue is scraped into the siphon head 17 and retained inside. The scraped surface of the filter element 4 regains its filtering function, thereby minimizing the clogging effect of the filter residue on the filter element 4. The filter element 4 is rotated by the setting of the filtering mechanism, and the surface of the filter element 4 is cleaned by the scraper 16. After a period of filtration, as the filter residue in the siphon head 17 accumulates more and more, the control system controls the electric push cylinder 22 to push the slide core 21 downward and starts the closing timing until the bottom of the slide core 21 extends out of the sleeve. 20, the oil in the sliding core 21 flows into the filter residue chamber 10, and the rapeseed oil in the oil inlet pipe 2 flows into the sliding core 21 under the siphon effect. The rapeseed oil carries the filter residue through the through pipe 18 and flows into the sliding core 21, and finally flows out from the bottom of the sliding core 21 and enters the filter residue chamber 10. After the closing time ends, the control system lifts the sliding core 21 upward and resets it through the electric push cylinder 22. At this time, the filter residue accumulated in the siphon head 17 has been completely discharged into the filter residue chamber 10. In order not to waste the residual rapeseed oil in the filter residue, it is necessary to further separate the filter residue and rapeseed oil through a separation mechanism.

[0029] The separation mechanism includes a conveying chamber 24, a second servo motor 25 and a screw rod 26. The conveying chamber 24 is located at the bottom of the slag outlet 23. The screw rod 26 is rotatably installed in the conveying chamber 24. The second servo motor 25 is arranged outside the conveying chamber 24. The motor shaft of the second servo motor 25 is connected to the screw rod 26. A right-angle tube 31 is connected to the side of the conveying chamber 24 away from the second servo motor 25. A jacket tube 27 is installed on the right-angle tube 31. A return tube 32 is connected to the other end of the jacket tube 27. A filter bag 30 is connected between the right-angle tube 31 and the return tube 32. The bottom of the jacket tube 27 is connected to an oil return pipe 28. The filter residue and rapeseed oil mixture flows from the slag outlet 23 to the conveying chamber 24. In chamber 24, the control system controls the second servo motor 25 to be energized, and the second servo motor 25 drives the screw rod 26 to rotate. The screw rod 26 squeezes the filter residue and rapeseed oil mixture into the right-angle tube 31. As more and more filter residue and rapeseed oil mixture are pushed into the right-angle tube 31, the filter residue and rapeseed oil mixture is squeezed into the filter bag 30. As it is pushed higher and higher, the rapeseed oil leaks downward under the action of gravity, flows out of the filter bag 30 into the jacket pipe 27, and is then connected to the oil storage cylinder 1 through the return oil pipe 28. The filter residue continues to be pushed upward until it enters the return pipe 32 for discharge. Through the setting of the separation mechanism, the final separation of the filter residue and rapeseed oil is achieved, and the function of removing impurities is achieved.

[0030] The working principle of the present invention is as follows: the squeezed rapeseed oil is transported to the oil inlet pipe 2 through a pipeline, and at the same time the control system draws oil from the oil storage cylinder 1 through the oil extraction pipe 29, so that the gas in the oil storage cylinder 1 is reduced, forcing the rapeseed oil to pass through the filter element 4 and enter the oil storage cylinder 1, thereby filtering the rapeseed oil, and the filter residue in the rapeseed oil is retained by the filter element 4, and the filter residue finally enters the filter residue chamber 10 through the vertical pipe 19, and then the separation mechanism is used to further process the filter residue.

[0031] The sealing ring 5 plays a sealing role between the rotating ring 6 and the filter 3 to prevent rapeseed oil from leaking into the filter 3. During the filtering process of the rapeseed oil, the control system enables the first servo motor 13 to be powered on, and the first servo motor 13 drives the active sprocket to rotate. The active sprocket drives the driven sprocket 15 to rotate through the chain 14, and the driven sprocket 15 drives the rotating shaft 8 to rotate. The rotating shaft 8 rotates the worm 7, and the worm 7 drives the rotating ring 6 to rotate through the worm wheel groove. When a rotating shaft 8 rotates, the connection transmission between the bevel gears 9 causes the rotating ring 6 in each filter 3 to rotate.

[0032] Since the position of the scraper 16 is fixed, the filter element 4 in the rotating ring 6 moves in accordance with the scraper 16, and the filter residue trapped on the filter element 4 is scraped off by the scraper 16 and squeezed into the siphon head 17. Since the top of the long chute of the sliding core 21 is connected to the outside, and since the top height of the sliding core 21 is higher than the oil inlet pipe 2, the rapeseed oil will not overflow from the top of the vertical pipe 19 through the sliding core 21 under the state of atmospheric pressure balance. The rapeseed oil keeps flowing to prevent the scraped filter residue from diffusing in the opposite direction. The filter residue is scraped into the siphon head 17 and retained inside. The surface of the scraped filter element 4 restores the filtering function, thereby minimizing the clogging effect of the filter residue on the filter element 4. By setting the filtering mechanism, the filter element 4 is rotated, and the scraper 16 is used to clean the surface of the filter element 4. After a period of filtration, as the filter residue in the siphon head 17 accumulates more and more, the control system controls the electric push cylinder 22 to push the slide core 21 downward and starts the closing timing until the bottom of the slide core 21 extends out of the sleeve 20, and the oil in the slide core 21 flows into the filter residue chamber 10. The rapeseed oil in the oil inlet pipe 2 flows into the slide core 21 under the siphon effect, and the rapeseed oil carries the filter residue through the through pipe 18 and flows into the slide core 21, and finally flows out from the bottom of the slide core 21 and enters the filter residue chamber 10. After the closing timing ends, the control system lifts the slide core 21 upward and resets it through the electric push cylinder 22. At this time, the filter residue accumulated in the siphon head 17 has been completely discharged into the filter residue chamber 10. In order not to waste the residual rapeseed oil in the filter residue, it is necessary to further separate the filter residue and rapeseed oil through a separation mechanism.

[0033] The filter residue and rapeseed oil mixture flows into the conveying chamber 24 from the residue outlet 23, the control system controls the second servo motor 25 to be energized, the second servo motor 25 drives the screw rod 26 to rotate, the screw rod 26 squeezes the filter residue and rapeseed oil mixture into the right-angle tube 31, as more and more filter residue and rapeseed oil mixture are pushed into the right-angle tube 31, the filter residue and rapeseed oil mixture is squeezed into the filter bag 30, as it is pushed higher and higher, the rapeseed oil leaks downward under the action of gravity, flows out of the filter bag 30 into the jacket pipe 27, and is then connected to the oil storage cylinder 1 through the return oil pipe 28, the filter residue continues to be pushed upward until it enters the return pipe 32 for discharge, and the final separation of the filter residue and rapeseed oil is achieved through the setting of the separation mechanism, and the function of removing impurities is achieved.
