Description

Technical Field

[0001] This invention relates to the field of acidified oil production technology, and in particular to an acidified oil reaction tank and its usage method. Background Technology

[0002] Acidified oil refers to oil obtained by acidifying soapstock, a byproduct of oil refining plants. The acidification process mainly involves mixing in a reaction tank. Acidified oil is essentially fatty acid, containing pigments and various components such as unacidified triglycerides, diglycerides, and monoglycerides. Depending on the source of the oil, acidified oil exhibits different distributions of saturated and unsaturated carbon chains.

[0003] Existing equipment for producing acidified oil from soap residue mainly consists of reaction tanks. However, due to the high viscosity and poor fluidity of soap residue, it cannot fully contact sulfuric acid in the reaction tank, which easily leads to uneven reaction. Therefore, a pump is needed to continuously circulate the material in the reaction tank. However, the mixing effect of the material by the pump is poor, resulting in a long acidification reaction time, which cannot meet the needs of industrial production. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of low efficiency in producing acidified oil through reaction tanks in the prior art, and to propose an acidified oil reaction tank and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An acidified oil reaction tank includes a tank body with a discharge pipe at the lower end and a tank cover that mates with the tank body at the upper end. The tank body also includes: a drive shaft rotatably connected to the top of the tank cover; the lower end of the drive shaft has a sliding hole; the lower end of the drive shaft has a rotating shaft coaxial with it; the upper end of the rotating shaft is longitudinally slidably connected within the sliding hole; and multiple circumferentially distributed stirring rods are fixedly installed on the outer wall of the lower end of the rotating shaft. A drive unit is disposed at the upper end of the tank cover, wherein the drive unit drives the drive shaft to rotate continuously, and a lifting mechanism for driving the rotating shaft to slide up and down is provided within the sliding hole.

[0007] In order to drive the stirring rod to efficiently stir the material in the tank, preferably, the driving unit includes an inverted L-shaped plate fixedly connected to the upper end of the tank cover, wherein a drive motor is fixedly installed on the inner top of the inverted L-shaped plate, a drive gear is fixedly installed on the output end of the drive motor, a driven gear is fixedly installed on the outer wall of the drive shaft, and the drive gear and the driven gear are meshed together.

[0008] To enable the stirring rod to sweep circumferentially while simultaneously sliding up and down, the lifting mechanism further includes a vertical rod fixedly connected to the top of the inverted L-shaped plate. The axis of the vertical rod is collinear with the axis of the drive shaft. The lower end of the vertical rod extends into a sliding hole and is fixedly connected to a first reciprocating screw. The upper end of the rotating shaft is provided with a device hole. The outer wall of the first reciprocating screw is threadedly connected to a first reciprocating slider that mates with it. The first reciprocating slider is fixedly connected to the upper port of the device hole.

[0009] To further spray the mixture from the upper surface of the material into the material, each of the multiple stirring rods is provided with a first horizontal tube, and the outer wall of each of the multiple stirring rods is provided with multiple thin tubes communicating with the first horizontal tube. The rotating shaft is provided with a vertical tube communicating with the first horizontal tube, and the upper end of the vertical tube is connected to the inner bottom of the device hole. The device hole is provided with a negative pressure component.

[0010] To enable the device orifice to automatically draw the mixed liquid from the material through the suction nozzle, the negative pressure assembly further includes a piston fixedly connected to the lower end of the first reciprocating screw. The piston is slidably connected inside the device orifice. The lower end of the device orifice is provided with a suction tube extending to the outer wall of the rotating shaft. One-way valves are fixedly installed inside both the suction tube and the vertical tube. The end of the suction tube is connected to a second horizontal tube via a flexible hose. Multiple suction nozzles are fixedly installed at the lower end of the second horizontal tube and communicate with it. The second horizontal tube is connected to the outer wall of the rotating shaft via a rotation positioning mechanism.

[0011] To maintain a fixed horizontal height for the second horizontal tube, the rotary positioning mechanism further includes a sleeve that is longitudinally slidably connected to the outer wall of the rotating shaft. The outer wall of the sleeve is rotatably connected to a rotating tube, which is fixedly connected to the inner wall of the can lid via a connecting rod. One end of the second horizontal tube is mounted on the outer wall of the sleeve.

[0012] To enable the second horizontal tube to slide back and forth in a direction perpendicular to the axis of rotation, the outer wall of the sleeve is further rotatably connected to a long tube parallel to the second horizontal tube. A second reciprocating screw is fixedly connected inside the long tube, and a second reciprocating slider is threadedly connected to the outer wall of the second reciprocating screw. The second horizontal tube is fixedly connected to the second reciprocating slider. A guide tube parallel to the long tube is fixedly connected to the outer wall of the sleeve, and a guide rod is slidably connected inside the guide tube. The movable end of the guide rod is fixedly connected to the second horizontal tube. A ring gear is fixedly connected to the upper end of the rotating tube, and a driven gear is fixedly installed on the circumferential outer wall of the long tube. The driven gear meshes with the ring gear.

[0013] To further improve the efficiency of material discharge from the discharge pipe, the lower end of the rotating shaft is fixedly connected to a guide post coaxial with it, and a spiral blade is fixedly installed on the outer wall of the guide post.

[0014] To facilitate opening the lid at the top of the tank, preferably, a liquid filling pipe is fixedly connected to the upper end of the lid, and an end cap is detachably installed at the upper end of the liquid filling pipe; wherein, a telescopic device parallel to the rotating shaft is fixedly installed on the outer wall of the tank, and the telescopic end of the telescopic device is fixedly connected to the outer wall of the lid.

[0015] A method for using an acidified oil reaction tank, the operating steps are as follows:

[0016] Step 1: Open the tank lid at the top of the tank using the telescopic device, put the material into the tank, and then close the lid. Step 2: Start the drive motor, and the stirring rod sweeps around the tank to stir the material. Step 3: During the rotation of the shaft, the shaft will also drive the stirring rod to slide up and down due to the first reciprocating screw. Step 4: When the shaft slides down, the suction nozzle sucks the mixture from the upper surface of the material into the device hole. Step 5: When the shaft slides up, the thin tube on the outer wall of the stirring rod sprays the mixture from the device hole into the material. Step 6: When the shaft rotates, the suction nozzle will slide back and forth in a direction perpendicular to the shaft. Step 7: When the reaction is complete, open the valve on the discharge pipe to complete the discharge. Step 8: When the shaft slides up and down, the guide column will slide up and down at the upper end of the discharge pipe.

[0017] Compared with the prior art, the present invention provides an acidified oil reaction tank, which has the following beneficial effects:

[0018] 1. This acidified oil reaction tank can be driven by a drive motor to rotate the drive shaft, which in turn drives the lower rotating shaft to rotate. The rotating shaft then drives the stirring rod on the outer wall to stir the raw materials inside the tank, thereby greatly improving the mixing efficiency of the raw materials and thus increasing the production efficiency of acidified oil.

[0019] 2. In this acidified oil reaction tank, the rotating shaft drives the first reciprocating slider to rotate synchronously. The first reciprocating slider then drives the rotating shaft to slide up and down in the sliding hole. This causes the rotating shaft to sweep the stirring rod in a circular motion while simultaneously sliding up and down, which further improves the stirring efficiency of the stirring rod and thus further improves the production efficiency of acidified oil.

[0020] 3. In this acidified oil reaction tank, when the rotating shaft slides upward, the mixed liquid in the device hole will be discharged from the thin tube on the outer wall of the stirring rod into the material at the bottom of the tank, thereby effectively mixing the solution on the upper surface of the material into the material, further improving the mixing efficiency of the material. On the other hand, the circumferentially sweeping stirring rod can make the thin tube spray the mixed liquid into the material more evenly, thereby further improving the uniformity of the material mixing.

[0021] 4. In this acidified oil reaction tank, when the sleeve rotates, the long tube will sweep synchronously around the second horizontal tube. Thus, while the second horizontal tube drives the suction nozzle to sweep around the rotating shaft, it will also drive the suction nozzle to slide back and forth in a direction perpendicular to the rotating shaft, which can further improve the uniformity of the mixture absorbed by the suction nozzle.

[0022] 5. The rotating shaft of this acidified oil reaction tank can also drive the guide column to rotate, which in turn drives the spiral blades to rotate. The spiral blades allow the material in the tank to be discharged from the discharge pipe more efficiently. On the other hand, the rotating shaft, which slides up and down, also drives the guide column to slide up and down, thus giving the material a downward pressure, making it less likely for the material to get stuck in the discharge pipe.

[0023] 6. The liquid addition pipe allows workers to easily add solution midway. When the tank lid needs to be closed, the telescopic device slides the lid upward to open the lid at the top of the tank, making it convenient for workers to put materials into the tank. When closing the lid, the telescopic device slides the lid downward to reset it. The whole process is simple to operate.

[0024] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention can effectively improve the mixing and reaction efficiency of acidified oil raw materials through the stirring rod inside the tank, thereby effectively improving the production efficiency of acidified oil.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1:

[0037] Reference Figures 1-8 An acidified oil reaction tank includes a tank body 1 with a discharge pipe 3 at the lower end, a valve for opening and closing installed on the discharge pipe 3, and a tank cover 2 that cooperates with the tank body 1 at the upper end. When the tank cover 2 is opened, the upper port of the tank body 1 is larger, which is convenient for placing viscous materials. The tank body 1 also includes a drive shaft 7, which is rotatably connected to the top of the tank cover 2. The lower end of the drive shaft 7 is provided with a sliding hole 8, and the lower end of the drive shaft 7 is provided with a rotating shaft 5 coaxial with it. The upper end of the rotating shaft 5 is longitudinally slidably connected in the sliding hole 8. Multiple circumferentially distributed stirring rods 6 are fixedly installed on the outer wall of the lower end of the rotating shaft 5. The drive unit is located at the upper end of the tank cover 2. The drive unit is used to drive the drive shaft 7 to rotate continuously. The sliding hole 8 is provided with a lifting mechanism for driving the rotating shaft 5 to slide up and down.

[0038] In use, after the material is placed into the tank 1, the drive unit can drive the drive shaft 7 to rotate, which in turn drives the lower rotating shaft 5 to rotate. The rotating shaft 5 drives the stirring rod 6 on the outer wall to stir the raw materials in the tank 1, thereby greatly improving the mixing efficiency of the raw materials and thus improving the production efficiency of acidified oil. The lifting mechanism can drive the rotating shaft 5 to slide up and down in the sliding hole 8, so that the rotating shaft 5 drives the stirring rod 6 to sweep around the circumference while sliding up and down, which can further improve the stirring efficiency of the stirring rod 6 in stirring the material, thereby further improving the production efficiency of acidified oil.

[0039] Furthermore, a liquid filling pipe 12 is fixedly connected to the upper end of the tank cover 2, and an end cap can be detachably installed at the upper end of the liquid filling pipe 12; wherein, a telescopic device 4 parallel to the rotating shaft 5 is fixedly installed on the outer wall of the tank body 1. The telescopic device 4 is mainly used to drive the tank cover 2 to move up and down. It can be an electric telescopic rod or a hydraulic cylinder. The telescopic end of the telescopic device 4 is fixedly connected to the outer wall of the tank cover 2.

[0040] When in use, the liquid addition pipe 12 allows workers to easily add solution midway. When the tank lid 2 needs to be closed, the telescopic device 4 drives the tank lid 2 to slide upward, thereby opening the tank lid 2 at the top of the tank body 1, making it convenient for workers to put materials into the tank body 1. When closing the tank lid 2, the telescopic device 4 drives the tank lid 2 to slide downward and reset. The whole process is simple to operate.

[0041] Example 2:

[0042] Reference Figures 1-8 The implementation is basically the same as in Example 1, but further, a specific implementation scheme of the drive unit is disclosed.

[0043] The drive unit includes an inverted L-shaped plate 13 fixedly connected to the upper end of the can lid 2. A drive motor 9 is fixedly installed on the inner top of the inverted L-shaped plate 13. A drive gear 10 is fixedly installed on the output end of the drive motor 9. A driven gear 11 is fixedly installed on the outer wall of the drive shaft 7. The drive gear 10 and the driven gear 11 are meshed and connected.

[0044] During use, the telescopic device 4 drives the tank cover 2 to slide upward, thereby opening the tank cover 2 at the top of the tank body 1, making it convenient for workers to put materials into the tank body 1. When feeding, the liquid level of the material should completely submerge the second horizontal pipe 22. After feeding, the telescopic device 4 drives the tank cover 2 to slide downward and reset. Then, the drive motor 9 is started. The drive motor 9 will drive the driven gear 11 to rotate through the drive gear 10. The driven gear 11 will drive the drive shaft 7 to rotate. The drive shaft 7 will drive the lower rotating shaft 5 to rotate. The rotating shaft 5 will drive the stirring rod 6 on the outer wall to stir the raw materials in the tank body 1, thereby greatly improving the mixing efficiency of the raw materials and thus improving the production efficiency of acidified oil.

[0045] Example 3:

[0046] Reference Figures 3-8 Similar to Example 2, but further, a specific implementation scheme for the lifting mechanism is disclosed.

[0047] The lifting mechanism includes a vertical rod 14 fixedly connected to the top of the inverted L-shaped plate 13. The axis of the vertical rod 14 is collinear with the axis of the drive shaft 7. The lower end of the vertical rod 14 extends into the sliding hole 8 and is fixedly connected to a first reciprocating screw 15. The upper end of the rotating shaft 5 is provided with a device hole 17. The outer wall of the first reciprocating screw 15 is threadedly connected to a first reciprocating slider 16 that cooperates with it. When the first reciprocating screw 15 rotates, the first reciprocating slider 16 can slide linearly back and forth along the outer wall of the first reciprocating screw 15. The first reciprocating slider 16 is fixedly connected to the upper port of the device hole 17.

[0048] In use, the telescopic device 4 slides the tank lid 2 upwards, opening the upper part of the tank 1 and facilitating the loading of materials into the tank 1. During loading, the liquid level of the material should completely submerge the second horizontal pipe 22. After loading, the telescopic device 4 slides the tank lid 2 downwards to reset it. Then, the drive motor 9 is started. The drive motor 9 drives the driven gear 11 via the drive gear 10, which in turn drives the drive shaft 7. The drive shaft 7 then drives the lower rotating shaft 5, which in turn drives the stirring rod 6 on the outer wall to stir the raw materials inside the tank 1. This greatly improves the mixing efficiency of raw materials, thereby increasing the production efficiency of acidified oil. During the rotation of the rotating shaft 5, the rotating shaft 5 drives the first reciprocating slider 16 to rotate synchronously. The first reciprocating slider 16 slides up and down along the outer wall of the first reciprocating screw 15 under the action of the first reciprocating screw 15. Thus, the first reciprocating slider 16 drives the rotating shaft 5 to slide up and down in the sliding hole 8. This causes the rotating shaft 5 to drive the stirring rod 6 to sweep around the circumference while sliding up and down, which further improves the mixing efficiency of the stirring rod 6 and thus further improves the production efficiency of acidified oil.

[0049] Furthermore, the lower end of the rotating shaft 5 is fixedly connected to a guide column 33 coaxial with it. The outer wall of the guide column 33 is fixedly installed with a spiral blade 34. When the material is discharged using the discharge pipe 3, the rotating shaft 5 can also drive the guide column 33 to rotate, which in turn drives the spiral blade 34 to rotate. The spiral blade 34 can make the material in the tank 1 discharge from the discharge pipe 3 more efficiently. In practice, when stirring the material, the rotating shaft 5 is reversed, and when discharging the material, the rotating shaft 5 is forward-rotated. This can prevent the spiral blade 34 from pushing the material into the discharge pipe 3 during the stirring process. On the other hand, the rotating shaft 5, which slides up and down, can also drive the guide column 33 to slide up and down, thereby giving the material a downward pushing force, so that the material is not easy to get stuck in the discharge pipe 3.

[0050] Example 4:

[0051] Reference Figures 3-8 It is basically the same as Example 3, but further, a specific implementation scheme for making the material flow vertically is added.

[0052] Each of the multiple stirring rods 6 is provided with a first horizontal tube 19, and the outer wall of each of the multiple stirring rods 6 is provided with multiple thin tubes 20 that communicate with the first horizontal tube 19. The rotating shaft 5 is provided with a vertical tube 21 that communicates with the first horizontal tube 19. The upper end of the vertical tube 21 is connected to the inner bottom of the device hole 17. The device hole 17 is provided with a negative pressure component.

[0053] Because the soap residue in the material has high viscosity, the solution that reacts with the soap residue tends to float on the upper surface of the tank 1. As the rotating shaft 5 slides up and down, the negative pressure component draws the relatively viscous mixture from the upper surface of the material into the first horizontal pipe 19, and then sprays it through the thin pipe 20 onto the more viscous parts of the material. This allows the material in the tank 1 to convect vertically, further improving the mixing efficiency of the material and thus increasing the production efficiency of the acidified oil. On the other hand, the circumferentially sweeping stirring rod 6 can make the thin pipe 20 spray the mixture more evenly into the material, thereby further improving the uniformity of the mixing of the material and intermittently increasing the production efficiency of the acidified oil.

[0054] Example 5:

[0055] Reference Figures 3-8 Similar to Example 4, but with a further detail, a specific implementation scheme for the negative pressure component is disclosed.

[0056] The negative pressure assembly includes a piston 18 fixedly connected to the lower end of the first reciprocating screw 15. The piston 18 is slidably connected in the device hole 17. The lower end of the device hole 17 is provided with a suction pipe 24 extending to the outer wall of the rotating shaft 5. One-way valves are fixedly installed in both the suction pipe 24 and the vertical pipe 21. The one-way valves allow the suction pipe 24 to only suck in air or wash liquid, and the vertical pipe 21 to only vent air or drain liquid. The end of the suction pipe 24 is connected to a second horizontal pipe 22 through a hose 25. Multiple suction nozzles 23 are fixedly installed at the lower end of the second horizontal pipe 22 and are connected to it. The second horizontal pipe 22 is connected to the outer wall of the rotating shaft 5 through a rotation positioning mechanism. Rotation positioning can keep the second horizontal pipe 22 at the same height, ensuring that the suction nozzles 23 are immersed in the material for a long time.

[0057] When the rotating shaft 5 slides downwards, the piston 18 slides upwards within the device hole 17, creating a negative pressure within the device hole 17. This negative pressure draws air into the second horizontal pipe 22 through the suction pipe 24 and the hose 25. The second horizontal pipe 22 then draws the mixture from the upper surface of the tank 1 into the device hole 17 through the suction nozzle 23. When the rotating shaft 5 slides upwards, the piston 18 forces the mixture in the device hole 17 into the first horizontal pipe 19 through the vertical pipe 21. Finally, the mixture is discharged from the thin tube 20 on the outer wall of the stirring rod 6 into the material at the bottom of the tank 1, thus effectively... The solution on the upper surface of the material is mixed into the material, further improving the mixing efficiency of the material. On the other hand, the rotating shaft 5 will drive the sleeve 35 to rotate inside the rotating tube 36. The rotating tube 36 is restricted from rotating by the connecting rod 26. The rotating sleeve 35 will drive the second horizontal tube 22 to sweep around the tank 1, so that the suction nozzle 23 can more efficiently suck up the mixed liquid in the tank 1. Furthermore, the circumferentially sweeping stirring rod 6 can make the thin tube 20 spray the mixed liquid more evenly into the material, thereby further improving the uniformity of the material mixing.

[0058] Example 6:

[0059] Refer to Figures 3-8 Similar to Example 5, but further, a specific implementation scheme for the rotary positioning mechanism is disclosed.

[0060] The rotary positioning mechanism includes a sleeve 35 that is longitudinally slidably connected to the outer wall of the rotating shaft 5. A rotating tube 36 is rotatably connected to the outer wall of the sleeve 35, and the rotating tube 36 is fixedly connected to the inner wall of the can lid 2 via a connecting rod 26. One end of a second horizontal tube 22 is mounted on the outer wall of the sleeve 35. A long tube 27 parallel to the second horizontal tube 22 is rotatably connected to the outer wall of the sleeve 35. A second reciprocating screw 37 is fixedly connected inside the long tube 27. A second reciprocating slider 28 is threaded onto the outer wall of the second reciprocating screw 37. The tube 22 is fixedly connected to the second reciprocating slider 28. The outer wall of the sleeve 35 is fixedly connected to a guide tube 31 parallel to the long tube 27. A guide rod 32 is slidably connected inside the guide tube 31. The movable end of the guide rod 32 is fixedly connected to the second horizontal tube 22. The guide rod 32 can slide back and forth along the inner wall of the guide tube 31. The upper end of the rotating tube 36 is fixedly connected to a ring gear 29. A driven gear 30 is fixedly installed on the outer circumference of the long tube 27. The driven gear 30 meshes with the ring gear 29.

[0061] During use, the telescopic device 4 drives the tank cover 2 to slide upward, thereby opening the tank cover 2 at the top of the tank 1, making it convenient for workers to put materials into the tank 1. During feeding, the liquid level of the material should completely submerge the second horizontal pipe 22. After feeding, the telescopic device 4 drives the tank cover 2 to slide downward and reset. Then, the drive motor 9 is started. The drive motor 9 will drive the driven gear 11 to rotate through the drive gear 10. The driven gear 11 will drive the drive shaft 7 to rotate. The drive shaft 7 will drive the lower rotating shaft 5 to rotate. The rotating shaft 5 will drive the stirring rod 6 on the outer wall to stir the raw materials in the tank 1, thereby greatly improving the mixing efficiency of the raw materials and thus improving the production efficiency of acidified oil. When the rotating shaft 5 slides up and down, the rotating shaft 5 will slide up and down within the sleeve 35. The rotating pipe 36 will be restricted by the connecting rod 26 to the inner wall of the tank cover 2 and cannot rotate, thus affecting the long pipe 27 and the second horizontal pipe 22. The vertical position of the tube 22 is restricted to prevent the second horizontal tube 22 from exceeding the highest liquid level of the material in the tank 1, thus ensuring that the suction nozzle 23 is always submerged in the material. When the sleeve 35 rotates, the long tube 27 will synchronously sweep around the second horizontal tube 22. The long tube 27 will drive the driven gear 30 on the outer wall to sweep around the ring gear 29. The driven gear 30 will then drive the long tube 27 and the second reciprocating screw 37 to rotate synchronously under the action of the ring gear 29. The second reciprocating screw 37 will drive the second reciprocating slider 28 to slide back and forth along the inner wall of the long tube 27. The second reciprocating slider 28 will drive the second horizontal tube 22 to slide back and forth. Thus, while the second horizontal tube 22 drives the suction nozzle 23 to sweep around the rotating shaft 5, it will also drive the suction nozzle 23 to slide back and forth in a direction perpendicular to the rotating shaft 5, which can further improve the uniformity of the mixture sucked by the suction nozzle 23.

[0062] A method for using an acidified oil reaction tank, the operating steps are as follows:

[0063] Step 1: Open the tank cover 2 at the top of the tank 1 using the telescopic device 4, put the material into the tank 1, and then close the tank cover 2; Step 2: Start the drive motor 9, and the stirring rod 6 sweeps around the tank 1 to stir the material; Step 3: During the rotation of the rotating shaft 5, the rotating shaft 5 will also drive the stirring rod 6 to slide up and down due to the first reciprocating screw 15; Step 4: When the rotating shaft 5 slides down, the suction nozzle 23 sucks the mixture from the upper surface of the material into the device hole 17; Step 5: When the rotating shaft 5 slides up, the thin tube 20 on the outer wall of the stirring rod 6 sprays the mixture in the device hole 17 into the material; Step 6: When the rotating shaft 5 rotates, the suction nozzle 23 will slide back and forth in a direction perpendicular to the rotating shaft 5; Step 7: When the reaction is over, open the valve on the discharge pipe 3 to complete the discharge; Step 8: When the rotating shaft 5 slides up and down, the guide column 33 will slide up and down at the upper end of the discharge pipe 3.

[0064] In use, the tank cover 2 of this acidified oil reaction tank is opened by sliding the telescopic device 4 upwards, making it easier for workers to put materials into the tank 1. During feeding, the liquid level of the material should completely submerge the second horizontal pipe 22. After feeding, the tank cover 2 can be slid down and reset by the telescopic device 4. Then, the drive motor 9 is started. The drive motor 9 drives the driven gear 11 to rotate through the drive gear 10. The driven gear 11 drives the drive shaft 7 to rotate. The drive shaft 7 drives the lower rotating shaft 5 to rotate. The rotating shaft 5 drives the stirring rod 6 on the outer wall to stir the raw materials in the tank 1, which can greatly improve the mixing efficiency of the raw materials and thus improve the production efficiency of acidified oil.

[0065] During the rotation of the rotating shaft 5, the rotating shaft 5 will drive the first reciprocating slider 16 to rotate synchronously. The first reciprocating slider 16 will slide up and down along the outer wall of the first reciprocating screw 15 under the action of the first reciprocating screw 15. Thus, the first reciprocating slider 16 will drive the rotating shaft 5 to slide up and down in the sliding hole 8, thereby causing the rotating shaft 5 to drive the stirring rod 6 to sweep around the circumference while sliding up and down, which can further improve the efficiency of stirring the material by the stirring rod 6, and thus further improve the production efficiency of acidified oil.

[0066] Because of the high viscosity of soapstock, the solution reacting with it tends to float on the upper surface of the tank 1. Therefore, when the rotating shaft 5 slides downwards, the piston 18 slides upwards within the device hole 17, creating a negative pressure within the hole. This negative pressure is then drawn into the second horizontal tube 22 through the suction pipe 24 and the flexible hose 25. The second horizontal tube 22 then draws the mixture from the upper surface of the tank 1 into the device hole 17 through the suction nozzle 23. As the rotating shaft 5 slides upwards, the piston 18 forces the mixture from the device hole 17 into the first horizontal tube 19 through the vertical tube 21, and finally discharges it through the thin tube 20 on the outer wall of the stirring rod 6. The solution at the top of the material is effectively mixed into the material, further improving the mixing efficiency. On the other hand, the rotating shaft 5 drives the sleeve 35 to rotate inside the rotating tube 36. The rotating tube 36 is restricted from rotating by the connecting rod 26. The rotating sleeve 35 drives the second horizontal tube 22 to sweep around the inside of the tank 1, so that the suction nozzle 23 can more efficiently suck up the mixture in the tank 1. Furthermore, the circumferentially sweeping stirring rod 6 can make the thin tube 20 spray the mixture more evenly into the material, thereby further improving the uniformity of the material mixing.

[0067] When the sleeve 35 rotates, the long tube 27 will synchronously sweep around the second horizontal tube 22. The long tube 27 will drive the passive gear 30 on the outer wall to sweep around the ring gear 29. The passive gear 30 will drive the long tube 27 and the second reciprocating screw 37 to rotate synchronously under the action of the ring gear 29. The second reciprocating screw 37 will drive the second reciprocating slider 28 to slide back and forth along the inner wall of the long tube 27. The second reciprocating slider 28 will drive the second horizontal tube 22 to slide back and forth. Thus, while the second horizontal tube 22 drives the suction nozzle 23 to sweep around the rotating shaft 5, it will also drive the suction nozzle 23 to slide back and forth in a direction perpendicular to the rotating shaft 5, which can further improve the uniformity of the suction nozzle 23 in sucking up the mixture.

[0068] When discharging material using the discharge pipe 3, the rotating shaft 5 can also drive the guide column 33 to rotate, which in turn drives the spiral blade 34 to rotate. The spiral blade 34 allows the material in the tank 1 to be discharged from the discharge pipe 3 more efficiently. In practice, when stirring the material, the shaft 5 is reversed, and when discharging, the shaft 5 is rotated forward. This prevents the spiral blade 34 from pushing the material into the discharge pipe 3 during the stirring process. On the other hand, the reciprocating rotating shaft 5 also drives the guide column 33 to reciprocate up and down, thus giving the material a downward pressure, making it less likely for the material to get stuck in the discharge pipe 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
