Description

Technical Field

[0001] This invention relates to the field of vegetable oil processing, and more particularly to a vegetable oil soap residue oil-water separation device. Background Technology

[0002] Vegetable oils are oils extracted from the seeds, fruits, germs, or kernels of plants. They are important raw materials for human diets and industrial production, and have clear nutritional value. Soap residue, on the other hand, is an insoluble precipitate formed during the refining process of vegetable oils through an alkali-refining deacidification reaction. Soap residue can be processed using an oil-water separator to separate the oils from it.

[0003] However, in the actual separation process, after the oil-water separator separates the oil from the soap residue, the oil floats on the concentrated brine. At this time, due to the large cross-section of the device, the area of ​​the interface between the oil and the concentrated brine increases. As a result, when the oil on the concentrated brine is subsequently sucked out, it is not possible to fully absorb the oil at the interface, resulting in oil residue. The increased area of ​​the interface leads to an increase in the amount of oil residue, thus affecting the oil separation effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a vegetable oil soap foot oil-water separation device.

[0005] To achieve the above objectives, the technical solution adopted by this invention is as follows: a vegetable oil soap residue oil-water separation device, comprising a frame and a heating box fixedly installed on the upper end of the frame. An outlet pipe is fixedly connected to the upper front end of the heating box. Multiple connecting pipes are evenly distributed and fixedly connected to the lower end of the outlet pipe. The diameter of the connecting pipes near the middle of the outlet pipe is smaller than the diameter of the connecting pipes near the end of the outlet pipe. A No. 4 solenoid valve is installed on the outlet pipe. Separation pipes are rotatably connected to the ends of the multiple connecting pipes. Above the multiple separation pipes... Each component is coaxially equipped with a thin suction tube. A second solenoid valve is installed at the upper end of the thin suction tube. An oil suction tube is installed above the heating box. One end of the oil suction tube is fixedly connected to a main suction tube. The main suction tube penetrates into the interior of the heating box. The lower end of the main suction tube is flush with the outlet tube. The other end of the oil suction tube is fixedly connected to a secondary suction tube. A flexible tube is fixedly connected between the secondary suction tube and the thin suction tube. A first solenoid valve is installed at both ends of the oil suction tube. A push tube component is installed on one side of the box frame. The push tube component is connected to the separation tube and the thin suction tube.

[0006] Preferably, a No. 3 solenoid valve is installed at the lower end of the separation pipe, a receiving hopper is provided below the separation pipe, and a secondary discharge pipe is fixedly connected to the lower end of the receiving hopper. The secondary discharge pipe is fixed to the box frame.

[0007] Preferably, the upper end of the heating box has a feeding port, and a stirring shaft is rotatably installed inside the lower part of the heating box. One end of the stirring shaft extends out from the side of the heating box, and a gearbox is fixedly installed on the upper part of the other side of the box frame. The output end of the gearbox is fixed to the stirring shaft.

[0008] Preferably, a drive motor is fixedly installed on the lower part of the other side of the frame, and pulleys are coaxially embedded at the output end of the drive motor and the input end of the gearbox. A belt is connected between the two pulleys, and the lower end of the heating box is fixedly connected to the main discharge pipe.

[0009] Preferably, the pusher includes a threaded rod rotatably mounted on the front edge of one side of the box frame, a threaded sleeve screwed onto the outer surface of the threaded rod, a pusher extending from the front end of the threaded sleeve, a top pipe frame elastically mounted at the front end of the box frame, a hook extending from the end of the top pipe frame, the hook pressing against the pusher, and multiple connecting frames rotatably mounted in a linear array at the upper end of the top pipe frame, the ends of the connecting frames being rotatably connected to the lower part of the separation pipe.

[0010] Preferably, the upper end of the pusher extends to a fixed frame, the end of the fixed frame is fixedly mounted with a fixed seat, the front end of the fixed seat is elastically mounted with a clamping plate, the thin suction tube is clamped between the clamping plate and the fixed seat, a rod frame is rotatably mounted between the two ends of the threaded rod, the rod frame is fixed to the box frame, a servo motor is fixedly mounted at the upper end of the rod frame, the output end of the servo motor is fixed to the threaded rod, the pusher passes through the inside of the rod frame, and the pusher slides with the rod frame.

[0011] Preferably, an extension frame is fixedly installed at the front end of the box frame, and a hexagonal post is embedded through the end of the extension frame. The jacking frame is slidably installed on the outer surface of the hexagonal post. A limit cap is embedded at the lower end of the hexagonal post and fits against the lower end of the jacking frame. A return spring is wound around the outer side of the hexagonal post. The lower end of the return spring is fixed to the upper end of the jacking frame, and the upper end of the return spring is fixed to the lower end of the extension frame.

[0012] Preferably, the front end of the fixing seat has two T-shaped columns extending symmetrically. The clamping plate is slidably installed on the outer surface of the T-shaped columns. A tightening spring is wound around the outside of the T-shaped columns. The rear end of the tightening spring is fixed to the front end of the clamping plate, and the front end of the tightening spring is fixed to the front end of the T-shaped column.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. During the process of the main suction tube drawing out the oil floating on the concentrated brine, when it reaches the interface, the No. 4 solenoid valve on the outlet tube can be opened to allow the oil and concentrated brine at the interface in the heating box to flow out into the separation tube and separate into layers in the separation tube. At this time, under the restriction of the separation tube, the area of ​​the interface between the oil and concentrated brine is reduced, so that after the subsequent fine suction tube draws out the oil in the separation tube, only a small amount of oil remains at the interface, thereby improving the oil separation effect.

[0015] 2. By pulling the thin straw forcefully, the thin straw can slide between the clamp and the fixed base to change the height of the straw's suction end, thereby adapting to the different interface heights within the multiple separation tubes to suck out the grease and meet the usage requirements.

[0016] 3. The rotating threaded rod drives the threaded sleeve upward, which in turn lifts the hook frame via the pusher, causing the jacking pipe frame to move upward. At this time, the return spring deforms, and the upward-moving jacking pipe frame drives the connecting frame to move, synchronously pushing multiple separation pipes to rotate slowly around the connecting pipe. Subsequently, the threaded rod drives the threaded sleeve downward, at which point the return spring returns to its original deformation, pushing the jacking pipe frame downward, causing the separation pipes to rotate in the opposite direction and reset. This cycle continues, allowing the separation pipes to oscillate slowly, thus causing the concentrated brine inside the separation pipes to flow slightly, breaking the static fluid layer, reducing the viscous resistance between the grease and the concentrated brine, and allowing the grease to move upward more smoothly, i.e., accelerating the grease's rise, thereby shortening the separation time and improving the grease separation efficiency.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figures 1-8The illustrated vegetable oil soap residue oil-water separation device includes a frame 1 and a heating box 2 fixedly installed on the upper end of the frame 1. An outlet pipe 12 is fixedly connected to the upper front end of the heating box 2, allowing the oil and concentrated brine at the interface within the heating box 2 to flow into a separation pipe 8. Multiple connecting pipes 39 are evenly distributed and fixedly connected to the lower end of the outlet pipe 12. The diameter of the connecting pipes 39 near the middle of the outlet pipe 12 is smaller than that near the end of the outlet pipe 12, preventing the flowing oil and concentrated brine from concentrating in the middle separation pipe 8. A solenoid valve 38 is installed on the outlet pipe 12, controlling its opening and closing. The ends of the multiple connecting pipes 39 are rotatably connected to the separation pipe 8, connecting the separation pipe 8 and the outlet pipe 12. A thin suction tube 24 is coaxially arranged above each of the multiple separation pipes 8, with a solenoid valve 27 installed at the upper end of the thin suction tube 24. Solenoid valve 27 controls the opening and closing of the thin suction tube 24. An oil suction tube 22 is installed above the heating box 2, connected to an external suction pump to generate suction for grease extraction. Since this operation is existing technology and widely used, it is not described in detail here. One end of the oil suction tube 22 is fixedly connected to a main suction tube 20, which penetrates into the interior of the heating box 2. The lower end of the main suction tube 20 is flush with the outlet tube 12 for oil extraction. The other end of the pipe 22 is fixedly connected to the auxiliary suction pipe 18. The auxiliary suction pipe 18 and the fine suction pipe 24 are fixedly connected to the flexible hose 23. The flexible hose 23 can connect the auxiliary suction pipe 18 and the fine suction pipe 24 and ensure that the movement of the fine suction pipe 24 is not obstructed. Both ends of the oil suction pipe 22 are equipped with a No. 1 solenoid valve 21. The No. 1 solenoid valve 21 plays the role of controlling the opening and closing of the auxiliary suction pipe 18 and the main suction pipe 20. A push pipe component is provided on one side of the box frame 1. The push pipe component is connected to the separation pipe 8 and the fine suction pipe 24.

[0028] A No. 3 solenoid valve 29 is installed at the lower end of the separation pipe 8. The No. 3 solenoid valve 29 controls the opening and closing of the separation pipe 8. A receiving hopper 7 is set below the separation pipe 8. The lower end of the receiving hopper 7 is fixedly connected to the auxiliary discharge pipe 40. The auxiliary discharge pipe 40 is fixed to the box frame 1. The receiving hopper 7 can receive the concentrated brine discharged from the separation pipe 8 and discharge it through the auxiliary discharge pipe 40.

[0029] A feeding port 19 is provided at the upper end of the heating box 2. A stirring shaft 11 is rotatably installed inside the lower part of the heating box 2. One end of the stirring shaft 11 extends through the side of the heating box 2. A gearbox 10 is fixedly installed on the upper part of the other side of the box frame 1. The gearbox 10 plays a transmission role. The output end of the gearbox 10 is fixed to the stirring shaft 11. Soap foot and concentrated brine are added into the heating box 2 through the feeding port 19. When the liquid level is level with the outlet pipe 12, the addition is stopped. Then, the heating box 2 heats the soap foot and concentrated brine. At the same time, the drive motor 16 drives the stirring shaft 11 to rotate through the belt 14 and the gearbox 10 to stir the soap foot and concentrated brine, so that the oil in the soap foot can be separated and float on the concentrated brine.

[0030] A drive motor 16 is fixedly installed on the lower part of the other side of the frame 1. The output end of the drive motor 16 and the input end of the gearbox 10 are both coaxially fitted with pulleys 15. A belt 14 is connected between the two pulleys 15. The pulleys 15 serve to connect the belt 14. The belt 14 serves to connect the output end of the drive motor 16 and the input end of the gearbox 10. The lower end of the heating box 2 is fixedly connected to the main discharge pipe 17. The main discharge pipe 17 serves to discharge the concentrated brine and other substances in the heating box 2.

[0031] The pusher includes a threaded rod 4 rotatably mounted on the front edge of one side of the box frame 1. A threaded sleeve 31 is screwed onto the outer surface of the threaded rod 4. A pusher 32 extends from the front end of the threaded sleeve 31. The threaded sleeve 31 drives the pusher 32 to move. A jacking frame 36 is elastically mounted on the front end of the box frame 1. A hook frame 13 extends from the end of the jacking frame 36. The pusher 32 pushes the hook frame 13. The hook frame 13 is pressed against the pusher 32. Multiple connecting frames 37 are rotatably mounted in a linear array on the upper end of the jacking frame 36. The jacking frame 36 drives the connecting frames 37 to move. The end of the connecting frame 37 is rotatably connected to the lower part of the separation pipe 8.

[0032] A fixed frame 28 extends from the upper end of the pusher 32. A fixed seat 9 is fixedly installed at the end of the fixed frame 28. The fixed frame 28 serves to fix the fixed seat 9. A clamping plate 30 is elastically installed at the front end of the fixed seat 9. The thin suction tube 24 is clamped between the clamping plate 30 and the fixed seat 9. The fixed seat 9 and the clamping plate 30 serve to clamp the thin suction tube 24. A rod frame 3 is rotatably installed between the two ends of the threaded rod 4. The rod frame 3 is fixed to the box frame 1. The rod frame 3 serves to support the threaded rod 4. A servo motor 5 is fixedly installed at the upper end of the rod frame 3. The output end of the servo motor 5 is fixed to the threaded rod 4. The pusher 32 passes through the inside of the rod frame 3. The pusher 32 and the rod frame 3 slide together. The servo motor 5 serves to drive the threaded rod 4 to rotate.

[0033] An extension frame 6 is fixedly installed at the front end of the frame 1. A hexagonal post 33 is embedded through the end of the extension frame 6. The extension frame 6 serves to fix the hexagonal post 33. The jacking frame 36 is slidably installed on the outer surface of the hexagonal post 33. The hexagonal post 33 serves to guide the jacking frame 36. A limit cap 35 is embedded at the lower end of the hexagonal post 33. The limit cap 35 serves to position the downward movement of the jacking frame 36. The limit cap 35 fits against the lower end of the jacking frame 36. A return spring 34 is wound around the outside of the hexagonal post 33. The lower end of the return spring 34 is fixed to the upper end of the jacking frame 36. The return spring 34 serves to reset the moved jacking frame 36. The upper end of the return spring 34 is fixed to the lower end of the extension frame 6.

[0034] Two T-shaped posts 25 extend symmetrically from the front end of the fixed base 9. The clamping plate 30 is slidably installed on the outer surface of the T-shaped posts 25. The T-shaped posts 25 serve to guide the clamping plate 30. A tightening spring 26 is wound around the outside of the T-shaped posts 25. The rear end of the tightening spring 26 is fixed to the front end of the clamping plate 30, and the front end of the tightening spring 26 is fixed to the front end of the T-shaped posts 25. The tightening spring 26 can push the clamping plate 30 to clamp the thin straw 24 between the clamping plate 30 and the fixed base 9.

[0035] In use, soap shavings and concentrated brine are added to the heating tank 2 through the feeding port 19. Adding is stopped when the liquid level is equal to that of the outlet pipe 12. The tank is then heated by the heating tank 2. Simultaneously, the drive motor 16, via the belt 14 and gearbox 10, rotates the stirring shaft 11 to agitate the soap shavings and concentrated brine, allowing the oil in the soap shavings to separate and float on the concentrated brine. Then, the suction pipe 22 generates suction, drawing the oil floating on the concentrated brine through the main suction pipe 20. When the separation point is reached, the first solenoid valve 21 at the main suction pipe 20 is closed, and the first solenoid valve 21 at the auxiliary suction pipe 18 is opened. Simultaneously, the fourth solenoid valve 38 on the outlet pipe 12 is also opened to allow heating. The grease and concentrated brine at the interface in box 2 flow out into the separation tube 8. Then, the servo motor 5 drives the threaded rod 4 to rotate, which in turn moves the threaded sleeve 31 upwards. This upward movement, via the pusher 32, lifts the hook frame 13, causing the jacking tube frame 36 to move upwards. At this point, the return spring 34 deforms, and the upward-moving jacking tube frame 36 drives the connecting frame 37 to move, synchronously pushing multiple separation tubes 8 to slowly rotate around the connecting tube 39. Then, the threaded rod 4 moves the threaded sleeve 31 downwards, at which point the return spring 34 returns to its original deformation, pushing the jacking tube frame 36 downwards, causing the separation tubes 8 to rotate in the opposite direction and reset. This cycle repeats, allowing the separation tubes 8 to continuously and slowly oscillate, thus allowing the concentrated brine to flow slightly. To break the static fluid layer and reduce the viscous resistance between the grease and concentrated brine, the grease is allowed to move upward more smoothly, thus accelerating its rise and causing it to separate into layers within the separator tube 8. After separation, the separator tube 8 returns to a vertical position. At this point, the threaded sleeve 31 continues to move downward, separating the pusher 32 and the hook 13. Simultaneously, the thin suction tube 24, driven by the threaded sleeve 31, is inserted into the interior of the separator tube 8. Subsequently, the thin suction tube 24 can be pulled forcefully according to the different interface heights within the multiple separator tubes 8, allowing it to slide between the clamp 30 and the fixed base 9. This changes the height of the suction end of the thin suction tube 24 to match the interface height. Then, the suction tube 22 generates suction to draw the grease through the thin suction tube 24. 4. The grease in the separation tube 8 is sucked out. Under the restriction of the separation tube 8, the interface area between the grease and the concentrated brine is reduced, so that after the thin pipette 24 sucks out the grease in the separation tube 8, only a small amount of grease remains at the interface, thereby improving the grease separation effect. When the grease in part of the separation tube 8 is sucked out, the second solenoid valve 27 on the thin pipette 24 in that separation tube 8 can be closed, so that the other thin pipettes 24 can still maintain a negative pressure state to continue to suck out the grease that has not been sucked out in the other separation tubes 8. After the suction is completed, the third solenoid valve 29 and the main discharge pipe 17 can be opened to discharge the concentrated brine in the heating box 2 and the separation tube 8 for the next use.
