Description

Technical Field

[0001] This invention relates to the field of oil pressing and refining technology, specifically to a vegetable oil pressing and refining apparatus. Background Technology

[0002] Vegetable oils are fatty substances extracted from the seeds, pulp, or other parts of plants. The most common sources include soybeans, corn, sunflower seeds, olives, peanuts, rapeseed (such as canola seeds), coconuts, and palm fruits. Vegetable oil refining equipment refers to a series of devices and technologies used to process unrefined vegetable oils, aiming to remove impurities and undesirable properties from the raw vegetable oil to produce high-quality edible oils. Current vegetable oil refining steps typically use degumming tanks.

[0003] The patent with publication number CN219409651U discloses a vegetable oil degumming hydration tank, which relates to the field of oil processing technology. It includes a main tank body with a conical bottom fixedly connected to the bottom. An oil foot pipe is fixedly connected to the bottom of the conical bottom, and an oil outlet pipe is fixedly connected to the side of the conical bottom. A speed reducer is fixedly connected to the top of the main tank body, and a servo motor is fixedly connected to the top of the speed reducer. A linkage gear is coaxially connected to the bottom of the speed reducer's output shaft. A spring inside a spring rod allows the scraper to elastically support the conical surface of the conical bottom. When the bottom rod rotates horizontally and reciprocates vertically, it drives the scraper to rotate and scrape away the gelatinous material adhering to the inner surface of the conical bottom. This facilitates the concentration of oil residue and gelatinous material at the bottom of the conical bottom, making it easy to discharge and separate them through the oil foot pipe. This solves the problem of existing degumming hydration tanks where gum and residue in the crude oil tend to adhere to the conical surface at the bottom of the tank after settling downwards.

[0004] However, the aforementioned degumming hydration tank still has the following problems in actual use:

[0005] After use, the inner wall of the degumming hydration tank needs to be cleaned. The existing cleaning method is usually to soak the inside of the tank with food-grade cleaning agent. However, the degumming hydration tank has a large internal capacity, and filling it with cleaning solution at one time requires a lot of water, which can easily lead to water waste. Summary of the Invention

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figures 1-12A vegetable oil pressing and refining device includes a refining tank 1, a feed pipe 2 installed on one side of the refining tank 1, a sealing cover 3 installed on the refining tank 1, a dosing tank 5 installed on the sealing cover 3, a stirring motor 4 installed on the sealing cover 3, a stirring rod 11 installed at the output end of the stirring motor 4, and a spray pipe 16 installed inside the refining tank 1. A dosing component and a rotating mechanism are connected to the upper surface of the sealing cover 3. A support component is connected to the side of the sealing cover 3 near the refining tank 1. An air-filling component and a water-discharging component are connected to the other end of the support component. The upper end of the water-discharging component is connected to the dosing component. The output end of the rotating mechanism passes through the sealing cover 3 to the inside of the refining tank 1 and is connected to a transmission component. The other end of the transmission component is connected to the air-filling component. The outer wall of the air-filling component is connected to the inner wall of the sealing cover 3 and the refining tank 1. The lower end of the water-discharging component passes through the air-filling component to the bottom of the air-filling component and is connected to the spray pipe 16. The end of the stirring rod 11 away from the stirring motor 4 passes through the sealing cover 3, the support component, the air-filling component, and the water-discharging component.

[0035] The vegetable oil pressing and refining apparatus of this invention is structurally similar to existing vegetable oil pressing and refining apparatuses, such as the vegetable oil degumming and hydration tank disclosed in patent publication number CN219409651U. Figures 1 to 12 As shown, the vegetable oil pressing and refining apparatus of the present invention can be used according to the following steps:

[0036] 1. First, the vegetable oil that needs to be refined and purified is introduced into the refining tank 1 through the feed pipe 2. Then, it is mixed normally through the stirring rod 11 inside the refining tank 1 and the mixing agent or brine inside the dosing tank 5 until the refining and purification is completed. Then, it is discharged from the bottom of the refining tank 1 to the next process.

[0037] 2. After the refined vegetable oil inside the refining tank 1 has been discharged, in order not to affect the quality of subsequent refining processes, the inside of the refining tank 1 needs to be cleaned.

[0038] 3. Connect the end of the inflation component located outside the refining tank 1 to the external gas supply equipment and start supplying gas.

[0039] 4. When the external gas supply device supplies gas, the gas filling component located at one end of the refining tank 1 begins to expand. As the gas filling component expands, it will slowly fill the middle part of the refining tank 1, leaving only the space between the stirring rod 11 and the inner wall of the refining tank 1.

[0040] 5. During the process of the aeration component filling the interior of the refining tank 1, the nozzle 16 located at the lower end of the water outlet component will also descend until it reaches the bottom of the refining tank 1 (of course, this refers to the top of the stirring blade of the stirring rod 11).

[0041] 6. Then connect the external water supply equipment to the end of the dosing assembly located outside the refining tank 1, and then start injecting food-grade cleaning solution into the refining tank 1.

[0042] 7. The food-grade cleaning solution enters the water outlet assembly from the inside of the dosing assembly, then enters the spray nozzle 16 through the water outlet assembly, and finally is slowly injected into the cavity inside the refining tank 1 from the spray nozzle 16.

[0043] 8. At this time, because the interior of the refining tank 1 is partially filled by the air-filling component, this part of the space does not require cleaning fluid, thus achieving the purpose of saving water resources.

[0044] 9. When the cleaning fluid fills the interior of the refining tank 1 with water (referring to the space not separated by the air-filling component), the rotating mechanism can be turned on again.

[0045] 10. After the rotating mechanism is started, it will drive the transmission component to rotate. After the transmission component rotates, it will drive the inflation component to rotate inside the support component. During the rotation, it will drive the previously opened part to rotate together inside the refining tank 1, so that the cleaning liquid inside the refining tank 1 can flow, thereby improving the soaking and cleaning effect.

[0046] 11. After cleaning, turn off the rotating mechanism and retract the inflation component to its original state through the external air supply equipment. Then, discharge the cleaning fluid from the discharge pipe below the refining tank 1 to the outside for further processing. It is simple and quick.

[0047] It is important to note here that:

[0048] 1. External air supply equipment is existing technology, such as air pumps, so it will not be described in detail here.

[0049] 2. External water supply equipment is existing technology, such as water pumps, so it will not be described in detail here.

[0050] 3. While injecting cleaning fluid into the refining tank 1, the dosing tank 5 needs to be closed to prevent water from flowing back into the dosing tank 5 and contaminating the substances inside the dosing tank 5.

[0051] 4. The dosing tank 5 is generally used to add various reaction mixtures of enzymes and other beneficial substances. This is an existing vegetable oil production process technology, and will not be described in detail here.

[0052] As a preferred embodiment of the present invention, the rotating mechanism includes a rotating motor 6 and a transmission rod 22. The outer wall of the rotating motor 6 is fixedly connected to the upper surface of the sealing cover 3. The output shaft of the rotating motor 6 is fixedly connected to the upper end of the transmission rod 22. The lower end of the transmission rod 22 penetrates the sealing cover 3 to the interior of the refining tank 1, and the lower end of the transmission rod 22 is also connected to a transmission assembly.

[0053] More specifically, when it is necessary to control the rotation of the inflation component inside the refining tank 1, simply turn on the switch of the rotating motor 6. After the rotating motor 6 starts, the output shaft can drive the transmission rod 22 to rotate, and after the transmission rod 22 rotates, it can drive the transmission component to rotate.

[0054] As a preferred embodiment of the present invention, the transmission assembly includes a gear 23, a gear ring 13, and an air intake ring 30. The inner wall of the gear 23 is fixedly connected to the outer wall of the lower end of the transmission rod 22, the bottom surface of the gear ring 13 is fixedly connected to the upper surface of the air intake ring 30, and the other end of the air intake ring 30 is connected to the inflation assembly. The gear 23 and the gear ring 13 mesh.

[0055] More specifically, when the transmission rod 22 rotates, the transmission rod 22 will rotate together with the gear 23. After the gear 23 rotates, it will mesh with the gear ring 13 and rotate together. After the gear ring 13 rotates, it will rotate the air intake ring 30, and thus the air intake ring 30 will rotate together with the inflation component.

[0056] As a preferred embodiment of the present invention, the support assembly includes a suspension ring 12 and a support ring 25. The upper end of the suspension ring 12 is fixedly connected to the bottom surface of the sealing cover 3, the lower end of the suspension ring 12 is fixedly connected to the upper surface of the inner ring of the support ring 25, and the outer ring of the support ring 25 is connected to the inflation assembly.

[0057] More specifically, by setting up a support component, the inflation component can be supported in the first way, preventing it from shaking or even falling off inside the refining tank 1; secondly, when the transmission component rotates the inflation component, the rotation of the inflation component can be unaffected.

[0058] In a preferred embodiment of the present invention, the inflation assembly includes an inflation / extraction pipe 10, an upper baffle 14, a support plate 15, an exhaust ring 31, and an expansion assembly. A rotating cavity 17 is provided at the connection between the refining tank 1 and the sealing cover 3. The outer wall of the outer ring of the support plate 15 is rotatably connected to the inner wall of the rotating cavity 17. The upper surface of the support plate 15 is fixedly connected to the lower end of the upper baffle 14, and the upper surface of the support plate 15 is also movably connected to the lower end of the exhaust ring 31. An inlet ring 30 is located between the exhaust ring 31 and the upper baffle 14. The lower end of the inlet ring 30 is fixedly connected to the upper surface of the support plate 15. The outer walls of both the inlet ring 30 and the toothed ring 13 are rotatably connected to the side wall of the exhaust ring 31. The upper surface of plate 15 is provided with several air inlets 32. The cavity formed between air inlet ring 30 and air outlet ring 31 is matched and aligned with several air inlets 32. The upper end of the expansion component is connected to the bottom surface of support plate 15, and the air inlets 32 are connected to the interior of the expansion component. The inner sidewall of support plate 15 is connected to water outlet component. The side of air outlet ring 31 away from upper baffle 14 is fixedly connected to the side of support ring 25 away from suspension ring 12. The side of air outlet ring 31 away from upper baffle 14 is also fixedly connected to one end of inflation / extraction pipe 10. The upper end of inflation / extraction pipe 10 passes through support ring 25 and sealing cover 3 to the outside of sealing cover 3. Inflation / extraction pipe 10 is connected to the interior of air inlet 32.

[0059] More specifically, since the exhaust ring 31 is fixed to the support ring 25, it remains stationary relative to the sealing cover 3. Therefore, when the gear 23 rotates, the gear 23 itself remains stationary. At this time, the intake ring 30, support plate 15, expansion assembly, etc. connected to the gear ring 13 all rotate through the support plate 15 and the rotating cavity 17. When the expansion assembly rotates, it can carry the cleaning fluid inside the refining tank 1, thereby improving the cleaning effect.

[0060] As a preferred embodiment of the present invention, the expansion assembly includes a base plate 26 and two inflatable cloths 29, the two inflatable cloths 29 being one large and one small, the upper ends of the two inflatable cloths 29 being fixedly connected to the bottom surface of the support plate 15, the lower ends of the two inflatable cloths 29 being fixedly connected to the upper surface of the base plate 26, and the air inlet 32 ​​communicating with the cavity between the base plate 26 and the two inflatable cloths 29.

[0061] More specifically, under normal circumstances, the expansion component is not ventilated, has a low overall height, and will be tightly attached to the bottom of the support plate 15 due to air pressure.

[0062] When the external gas supply device starts supplying gas, the gas enters the cavity between the outlet ring 31 and the inlet ring 30 through the gas filling and extraction pipe 10, and enters the cavity between the two inflatable cloths 29 and the bottom plate 26 through the air inlet 32 ​​below this cavity. As more and more gas is supplied, it will push the bottom plate 26 downward until the two inflatable cloths 29 are fully unfolded. At this time, the gas supply stops. After that, even if the inside of the refining tank 1 is filled with cleaning fluid, it will not be easily "collapsed" by water pressure because there is gas between the two inflatable cloths 29.

[0063] It is important to note here that:

[0064] 1. A pressure sensor can be installed inside the base plate 26 to monitor the internal pressure in real time. When the set value is reached, the air supply can be stopped. Of course, other monitoring equipment can also be used, and there are no specific limitations.

[0065] 2. The two inflatable fabrics 29 can use accordion covers with good airtightness, so that when the inflatable fabrics 29 are expanded and contracted, they can only be expanded and contracted in a straight line, up and down.

[0066] As a preferred embodiment of the present invention, the bottom surface of the support plate 15 is fixedly connected to the lower baffle 28 and the inner ring 36, and two inflatable cloths 29 are located between the lower baffle 28 and the inner ring 36. The upper surface of the base plate 26 abuts against the bottom surface of the lower baffle 28 and the inner ring 36.

[0067] More specifically, by setting the lower baffle 28 and the inner ring 36, the air pressure inside the two base plates 26 and the inflatable cloth 29 can be drawn away, causing it to stick to the bottom of the support plate 15, so that the cylinder can be stored at the top.

[0068] As a preferred embodiment of the present invention, the upper surface of the support plate 15 is provided with an anti-detachment cavity 35, and the bottom surface of the air outlet ring 31 is fixedly connected with an anti-detachment ring 33. The anti-detachment ring 33 is located inside the anti-detachment cavity 35, and the outer wall of the anti-detachment ring 33 is slidably connected to the inner wall of the anti-detachment cavity 35.

[0069] More specifically, by setting up the anti-detachment cavity 35 and the anti-detachment ring 33, it is possible to ensure that the air outlet ring 31 provides support and suspension for the support plate 15 without hindering the rotation of the support plate 15.

[0070] In a preferred embodiment of the present invention, the dosing assembly includes a dosing pipe 7, a flushing pipe 8, a valve 9, a tee pipe 18, a support block 24, a connecting pipe 19, a diverter pipe 20, and several bellows hoses 21. The upper end of the dosing pipe 7 is fixedly connected to the lower end of the dosing tank 5, and the lower end of the dosing pipe 7 is fixedly connected to one end of the tee pipe 18. The other two ends of the tee pipe 18 are fixedly connected to the flushing pipe 8 and the connecting pipe 19, respectively. The other end of the flushing pipe 8 passes through the support block 24 and is fixedly connected to the inner wall of the support block 24. The valve 9... Installed inside the flushing pipe 8, the lower end of the connecting pipe 19 passes through the sealing cover 3 and is fixedly connected to the upper end of the diversion pipe 20. The other ends of the diversion pipe 20 are respectively fixedly connected to one end of several bellows hoses 21. The other ends of several bellows hoses 21 are all connected to the water outlet assembly. Several bellows hoses 21 are all located between the support plate 15 and the support ring 25. The dosing tank 5, dosing pipe 7, flushing pipe 8, tee pipe 18, connecting pipe 19, diversion pipe 20, several bellows hoses 21 and water flow assembly are internally connected.

[0071] More specifically, during normal processing of vegetable oil, valve 9 is closed, and then the chemical solution is pumped out through the dosing equipment (usually a metering pump) inside the dosing tank 5. The chemical solution then enters the water outlet assembly through the dosing pipe 7, the three-way pipe 18, the connecting pipe 19, the diversion pipe 20, and several bellows hoses 21. Finally, it is sprayed out from the nozzle 16 connected to the other end of the water outlet assembly into the refining tank 1.

[0072] During the later cleaning of the interior of the refining tank 1, the dosing equipment inside the dosing tank 5 is shut off, and then valve 9 is opened. After that, the external water supply equipment is connected to the flushing pipe 8, and water is supplied. The cleaning fluid supplied by the water supply equipment can also enter the interior of the water outlet assembly through the three-way pipe 18, the connecting pipe 19, the diversion pipe 20, and several bellows hoses 21. Then, it is sprayed out into the interior of the refining tank 1 from the spray pipe 16 connected to the other end of the water outlet assembly.

[0073] As a preferred embodiment of the present invention, the water outlet assembly includes a water pipe 27 and a connecting plate 34. The connecting plate 34 is sleeved and fixedly connected to the outer wall of the water pipe 27. The upper surface of the connecting plate 34 is fixedly connected to the bottom surface of the base plate 26. The lower end of the water pipe 27 is fixedly connected to one end of the nozzle 16. The upper end of the water pipe 27 is fixedly connected to the lower ends of several bellows hoses 21. The outer wall of the water pipe 27 is slidably connected to the inner ring 36 and the inner wall of the support plate 15. The bellows hoses 21, the water pipe 27 and the nozzle 16 are internally connected.

[0074] More specifically, when adding medicine or cleaning fluid into the refining tank 1, the liquid from the bellows hose 21 will enter the nozzle 16 through the water pipe 27 and then flow into the refining tank 1.

[0075] It should be noted that after the inflation component expands (i.e., the bottom plate 26 descends), the water pipe 27 is also located below the refining tank 1. At this time, the height difference between the water pipe 27 and the diversion pipe 20 can be compensated by the bellows hose 21.

[0076] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
