Description

A deodorizing device for cottonseed oil Technical Field

[0001] This invention relates to the field of cottonseed oil production technology, and more specifically to a deodorization device for cottonseed oil. Background Technology

[0002] Cottonseed oil deodorization often uses deodorization towers, which are mostly continuous shallow tray towers. The oil flows layer by layer inside the tower and is transferred from the upper layer to the lower layer through downcomers. The downcomers are not only material channels, but also play a crucial role in isolating the vapor space between the upper and lower trays by forming a "liquid seal" to prevent vapor short circuits. Trace amounts of colloids, polymer precursors, metallic soaps, and fine bleaching clay particles that were not completely removed during the decolorization process in the oil are very prone to clogging. The current solution is to shut down the tower for disassembly and maintenance.

[0003] The multi-layer shallow pan structure makes each layer of downcomer vulnerable to blockage. Even after clearing the upper downcomer, if the material is not removed, the lower downcomer will still be at risk of blockage. The material causing the blockage is always inside the downcomer, and the accumulation of material will inevitably lead to blockage, affecting the continuity of production. Therefore, a deodorization device is needed that can effectively remove scale inside the downcomer to avoid blockage, while ensuring the liquid seal required for the deodorization process.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] This invention provides a deodorizing device for cottonseed oil, which solves the problems that cottonseed oil is prone to clogging when passively flowing, and that scale is always present in the cottonseed oil, while continuing to actively push the flow when the liquid seal is unstable will destroy the deodorizing vacuum environment.

[0006] To achieve the goal of actively pushing the flow and removing scale to reduce the risk of clogging when the liquid seal is stable, and pausing the active pushing flow to restore the passive flow channel of cottonseed oil when the liquid seal is unstable, this invention achieves this through the following technical solution: A deodorization device for cottonseed oil, including a deodorization tower, a shallow dish fixedly installed inside the deodorization tower, a steam pipe and a downcomer connected to the bottom of the shallow dish, the downcomer connected to a downcomer pipe, an anti-clogging mechanism inside the downcomer pipe, and a sealing drive mechanism on the steam pipe; the anti-clogging mechanism includes a rotating shaft rotatably installed inside the downcomer pipe, and the sealing drive mechanism is used to drive the rotating shaft to rotate. The device is movable, with a spiral guide plate fixedly connected to the rotating shaft. An installation ring is fixedly connected to the outer surface of the rotating shaft below the spiral guide plate. Several telescopic rods are rotatably connected to the installation ring. The telescopic rods are radially distributed around the axis of the rotating shaft, and a flexible screen is connected between adjacent telescopic rods. The side wall of the downcomer has two layers of flow ports, with a partition screen on the lower flow port. A receiving tube is detachably installed on the outer wall of the downcomer, connecting the upper and lower flow ports. When the telescopic rods extend, the flexible screen cooperates with the side wall of the downcomer between the upper and lower flow ports.

[0007] Furthermore, an arc-shaped guide plate is fixedly connected to the inner wall of the liquid descending hopper, and the arc-shaped guide plate is located above the upper flow port.

[0008] Furthermore, the sealing drive mechanism includes a steam jet pump, the output end of which is fixedly connected to a steam pipe. A steam branch pipe is connected and fixedly connected to the steam pipe adjacent to the shallow dish. A venturi tube is fixedly connected and connected to the steam branch pipe. A turbine is fixedly installed on the throat of the inner wall of the venturi tube. A magnetic coupling is fixedly connected to the turbine shaft. The magnetic coupling is rotatably connected to the venturi tube. A magnetic rotor is fixedly connected to the bottom of the rotating shaft. The magnetic rotor is magnetically connected to the magnetic coupling. The rotating shaft and the magnetic coupling are located on the same vertical line.

[0009] Furthermore, the inner wall of the liquid-falling hopper is fixedly connected with two mounting rods, which are distributed vertically. A rotating shaft is rotatably connected between the two mounting rods and extends to the bottom of the lower mounting rod.

[0010] Furthermore, a liquid seal stabilizing mechanism is provided at the bottom of the shallow pan. The liquid seal stabilizing mechanism includes a mounting frame fixedly installed at the bottom of the shallow pan, and the mounting frame is located adjacent to the descending hopper. A vibration sensor is fixedly installed on the mounting frame, and the sensing end of the vibration sensor contacts the bottom of the outer surface of the shallow pan. The vibration sensor is used to monitor the vibration spectrum when cottonseed oil flows into the descending hopper in the shallow pan. An electric valve and a one-way valve are fixedly installed and connected on the steam branch pipe. The electric valve is located between the venturi tube inlet and the steam pipe, and the one-way valve is located between the venturi tube outlet and the steam pipe. Two sets of connecting rings are provided at the bottom of the telescopic rod and the bottom of the mounting ring. Each set of connecting rings has two rings, and the two connecting rings in the same set are interlocked. One end of each set of connecting rings is fixedly connected to the bottom of the telescopic rod and the bottom of the mounting ring, respectively, and a spring is fixedly connected between the other ends of the two sets of connecting rings.

[0011] Furthermore, when the vibration spectrum monitored by the vibration sensor deviates from the stable range, it is determined that the flow is unstable, and the electric valve is controlled to cut off the steam in the steam branch pipe, the shaft stops rotating, and the telescopic rod and flexible screen rotate downward.

[0012] Furthermore, a collecting hopper is fixedly connected to the outer surface of the rotating shaft near the bottom. The collecting hopper has several sieve holes. When the spring returns to its original position, the telescopic rod rotates downward, and the end of the telescopic rod away from the mounting ring is located above the collecting hopper.

[0013] This invention has the following beneficial effects: The deodorizing device for cottonseed oil uses a venturi tube installed in a steam branch to utilize the kinetic energy of the steam in the deodorizing tower as the driving force. A turbine is added to convert the driving force into rotation. The magnetic coupling and magnetic rotor work together to achieve sealed transmission, solving the problem of dynamic seal leakage. The magnetic rotor generates a pumping thrust on the downward-flowing cottonseed oil through the spiral guide plate. At the same time, the centrifugal force generated by the rotation opens the flexible screen, allowing the actively pushed cottonseed oil to pass through the screen. The scale that does not pass through the screen flows to the flow port at the bottom of the arc-shaped guide plate for scale recovery. The arc-shaped guide plate prevents the downward-flowing cottonseed oil from flowing into the flow port, playing a guiding and blocking role. At the same time, a vibration sensor is set to monitor the vibration amplitude of the cottonseed oil flow. When the vibration spectrum deviates from the stable range, the electric valve stops the flow of the steam branch and stops the rotation of the shaft. The restoring force of the spring drives the telescopic rod to retract the flexible screen, so that the cottonseed oil flows passively while avoiding the screen affecting the flow stability, thus achieving liquid seal stability.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Please refer to Figures 1-9. An embodiment of the present invention provides a technical solution: a deodorizing device for cottonseed oil, including a deodorizing tower 1, a shallow dish 4 fixedly installed inside the deodorizing tower 1, a steam pipe 3 and a downcomer 6 connected to the bottom of the shallow dish 4, the downcomer 6 connected to a downcomer pipe 5, an anti-blocking mechanism inside the downcomer 6, and a sealing drive mechanism provided in the steam pipe 3.

[0020] A liquid seal stabilizing mechanism is provided at the bottom of the shallow pan 4. The liquid seal stabilizing mechanism includes a mounting frame 7 fixedly installed at the bottom of the shallow pan 4, and the mounting frame 7 is located adjacent to the descending hopper 6. A vibration sensor 14 is fixedly installed on the mounting frame 7. The sensing end of the vibration sensor 14 contacts the bottom of the outer surface of the shallow pan 4. The vibration sensor 14 is used to monitor the vibration spectrum when cottonseed oil in the shallow pan 4 flows into the descending hopper 6. An electric valve 10 and a one-way valve 11 are fixedly installed and connected on the steam branch pipe 8. The electric valve 10 is located between the input end of the venturi tube 9 and the steam pipe 3. The one-way valve 11 is located between the output end of the venturi tube 9 and the steam pipe 3. Two sets of connecting rings 23 are provided at the bottom of the telescopic rod 19 and the bottom of the mounting ring 22. There are two sets of connecting rings 23 in each set, and the two connecting rings 23 in the same set are interlocked. One end of each set of connecting rings 23 is fixedly connected to the bottom end of the telescopic rod 19 and the bottom of the mounting ring 22, respectively. A spring 21 is fixedly connected between the other ends of the two sets of connecting rings 23.

[0021] The internal structure and working principle of the deodorization tower 1 are existing technologies. The steam jet pump 2 is fixedly installed on the outer surface of the deodorization tower 1. One end of the steam pipe 3 is fixedly connected to the output end of the steam jet pump 2, and the other end of the steam pipe 3 extends into the deodorization tower 1. The steam jet pump 2 is existing technology. A control host is placed outside the deodorization tower 1. The signal conditioning circuit of the vibration sensor 14 is installed outside the deodorization tower 1 near the vibration sensor 14. The data acquisition unit is fixedly installed inside the control host. The controller of the electric valve 10 is fixedly installed inside the control host. All of the above are existing technologies.

[0022] During deodorization, the steam jet pump 2 outputs high-temperature steam into the shallow dish 4 through the steam pipe 3 for deodorization. After the cottonseed oil flows in the shallow dish 4, it enters the downcomer pipe 5 through the downcomer 6.

[0023] The anti-clogging mechanism includes a rotating shaft 16 rotatably installed inside the descending hopper 6. Two mounting rods 15 are fixedly connected to the inner wall of the descending hopper 6, arranged vertically. The rotating shaft 16 is rotatably connected between the two mounting rods 15, extending to the bottom of the lower mounting rod 15. A sealing drive mechanism drives the rotating shaft 16 to rotate. A spiral guide plate 17 is fixedly connected to the rotating shaft 16. An mounting ring 22 is fixedly connected to the outer surface of the rotating shaft 16 below the spiral guide plate 17. Several telescopic rods 19 are rotatably connected to the mounting ring 22. The telescopic rods 19 rotate... The shaft 16 is radiating outwards from its center. Flexible screens 20 are connected between adjacent telescopic rods 19. The side wall of the downcomer 6 has two layers of flow ports, with a partition 26 on the lower flow port. A receiving tube 25 is detachably installed on the outer wall of the downcomer 6, connecting the upper and lower flow ports. When the telescopic rod extends, the flexible screen 20 engages with the side wall of the downcomer 6 between the upper and lower flow ports. A sealing drive mechanism is used to drive the rotating shaft to rotate. An anti-blocking mechanism is provided on the rotating shaft 16. A liquid seal stabilizing mechanism is provided at the bottom of the shallow dish 4 to stabilize the liquid seal state of the deodorization environment.

[0024] When the rotating shaft 16 rotates, it generates centrifugal force. Under the action of centrifugal force, the telescopic rod 19 overcomes the tension of the spring 21 and extends outward and upward. That is, the telescopic rod 19 extends and rotates upward, driving the flexible screen 20 to expand radially.

[0025] There are several containment tubes 25, and the number of containment tubes 25 is the same as the number of lower-level flow ports. The upper and lower ends of the containment tubes 25 are fixedly connected to the upper and lower flow ports respectively and flow through them.

[0026] When the screen 20 is fully extended, its edge connects precisely to the upper flow port inside the descending hopper 6. Simultaneously, the spiral guide plate 17 on the rotating shaft 16 rotates with the shaft, applying a downward axial thrust to the cottonseed oil flowing into the descending hopper 6, promoting its downward flow. Under the pushing and guiding force of the spiral guide plate 17 within the descending hopper 6, most of the cottonseed oil flows vertically downward through the central area, while some oil flowing along the edge is captured by the arc-shaped guide plate 24 and guided downwards towards the surface of the screen 20. As the flowing cottonseed oil passes through the screen 20, the oil contained within... Solid scale particles and larger polymeric impurities are trapped by the screen 20. The screened impurities slide down the inclined surface of the screen 20 under their own gravity into the upper flow port and fall into the receiving tube 25 connected to it for temporary storage. The oil adhering to the surface of the impurities flows back into the downcomer 6 after passing through the partition 26 at the bottom of the receiving tube 25, and continues to flow down into the downcomer 5. The filtered clean cottonseed oil passes through the screen 20 and enters the downcomer 5. When the system needs maintenance, the receiving tube 25 can be removed by unscrewing the screws to clean the accumulated impurities.

[0027] The sealing drive mechanism includes a steam jet pump 2, the output end of which is fixedly connected to a steam pipe 3. A steam branch pipe 8 is connected to and fixedly connected to a shallow dish 4 adjacent to the steam pipe 3. A venturi tube 9 is fixedly connected to and connected to the steam branch pipe 8. A turbine 12 is fixedly installed on the throat of the inner wall of the venturi tube 9. A magnetic coupling 13 is fixedly connected to the shaft of the turbine 12. The magnetic coupling 13 is rotatably connected to the venturi tube 9. A magnetic rotor 18 is fixedly connected to the bottom of the rotating shaft 16. The magnetic rotor 18 is magnetically connected to the magnetic coupling 13. The rotating shaft 16 and the magnetic coupling 13 are located on the same vertical line.

[0028] The specific structure and working principle of the Venturi tube 9 are existing technologies, and the magnetic rotor 18 is a neodymium iron boron strong magnet.

[0029] When the vibration spectrum is within the normal range that characterizes stable flow, the electric valve 10 is in the open state, and a portion of low-pressure steam is diverted from the main steam pipe 3 by the steam branch pipe 8. When the diverted steam passes through the throat of the venturi tube 9, it is accelerated to form a high-speed airflow and drives the turbine 12 to rotate at high speed. The rotation of the turbine 12 is transmitted to the downcomer 6 without contact through the magnetic coupling 13, which drives the magnetic rotor 18 magnetically coupled to it to rotate synchronously, thereby causing the fixedly connected rotating shaft 16 to rotate.

[0030] When the vibration spectrum monitored by the vibration sensor 14 deviates from the stable range, it is determined that the flow is unstable. The control electric valve 10 cuts off the steam in the steam branch pipe 8, the rotating shaft 16 stops rotating, the telescopic rod 19 and the flexible screen 20 rotate downward. A collection hopper 27 is fixedly connected to the outer surface of the rotating shaft 16 near the bottom. Several screen holes are opened on the collection hopper 27. When the spring 21 returns to its original position, the telescopic rod 19 rotates downward, and the end of the telescopic rod 19 away from the mounting ring 22 is located above the collection hopper 27.

[0031] When vibration sensor 14 detects that the vibration spectrum deviates from the stable range, indicating that abnormal fluctuations in the feed flow rate from shallow pan 4 to downcomer 6 may damage the liquid seal of downcomer 5, the control unit immediately issues a command to close electric valve 10, cutting off the drive steam supply to venturi tube 9. One-way valve 11 prevents steam backflow into steam branch pipe 8, turbine 12 loses power and stops rotating, the transmission of magnetic coupling 13 stops, the centrifugal force of shaft 16 disappears, connecting spring 21 pulls telescopic rod 19 inward to retract and reset, and flexible screen 20 retracts and detaches from the upper flow port. The annular channel is fully opened, and the rotating shaft 16 stops rotating. The pushing action of the spiral guide plate 17 also stops immediately. At this time, the oil flow in the downcomer 6 flows down naturally by gravity. All mechanical actions that may obstruct the flow stop, thus completely avoiding any interference with the unstable liquid seal state and ensuring the stability of the core deodorization process. After the rotating shaft 16 stops rotating, the collection hopper 27 at its bottom is stationary above the inlet of the downcomer 5. It is used to catch large impurities that may accidentally fall from the screen 20 or the receiving tube 25, preventing them from falling directly into and clogging the downcomer 5.

[0032] Working principle: During deodorization, the steam jet pump 2 outputs high-temperature steam to the shallow pan 4 through the steam pipe 3 for deodorization. After cottonseed oil flows in the shallow pan 4, it enters the downcomer pipe 5 through the downcomer 6. The vibration sensor 14 monitors the vibration spectrum generated by the oil flow at the bottom of the shallow pan 4 in real time. When the vibration spectrum is within the normal range that indicates stable flow, the electric valve 10 is in the open state, and the steam branch pipe 8 diverts a portion of low-pressure steam from the main steam pipe 3. When this diverted steam passes through the throat of the venturi tube 9, it is accelerated to form a high-speed airflow and drives the turbine 12 to rotate at high speed. The rotation of the turbine 12 is transmitted to the downcomer 6 without contact through the magnetic coupling 13, which drives the magnetic rotor 18 magnetically coupled to rotate synchronously, thereby causing the fixedly connected rotating shaft 16 to rotate. 6. When rotating, centrifugal force is generated. Under the action of centrifugal force, the telescopic rod 19 overcomes the tension of the spring 21 and extends outward and upward. That is, the telescopic rod 19 extends and rotates upward, driving the flexible screen 20 to expand radially. When the screen 20 is fully expanded, its edge just connects to the upper flow port in the descending hopper 6. At the same time, the spiral guide plate 17 on the rotating shaft 16 rotates with the shaft, applying a downward axial thrust to the cottonseed oil flowing into the descending hopper 6 to promote its downward flow. Under the push and guidance of the spiral guide plate 17 in the descending hopper 6, most of the cottonseed oil flows vertically downward through the central area, while some of the oil flowing along the edge is captured by the arc-shaped guide plate 24 and guided downward to the surface of the screen 20. When the flowing cottonseed oil passes through the screen 20, the solid scale particles and larger particles contained therein are removed. Polymerized impurities are trapped by screen 20. The screened impurities slide down the inclined surface of screen 20 under their own gravity into the upper flow port and fall into the connected receiving tube 25 for temporary storage. The oil adhering to the surface of the impurities flows back into the downcomer 6 after passing through the partition 26 at the bottom of the receiving tube 25, and continues to flow downward into the downcomer 5. The filtered clean cottonseed oil passes through screen 20 and enters the downcomer 5. When the system needs maintenance, the receiving tube 25 can be removed by unscrewing the screws to clean the accumulated impurities. When the vibration sensor 14 detects that the vibration spectrum deviates from the stable range, that is, when it is determined that the abnormal fluctuation of the feed flow from the shallow pan 4 to the downcomer 6 may damage the liquid seal of the downcomer 5, the control host immediately issues a command to close the electric valve 10 and cut off the drive to the venturi tube 9. Steam supply is activated, and the one-way valve 11 prevents steam from flowing back into the steam branch pipe 8. The turbine 12 loses power and stops rotating, the transmission of the magnetic coupling 13 stops accordingly, the centrifugal force of the rotating shaft 16 disappears, the connecting spring 21 pulls the telescopic rod 19 to retract and reset, and the flexible screen 20 retracts and separates from the upper flow port, making the annular channel fully open. At the same time, the rotating shaft 16 stops rotating, and the pushing action of the spiral guide plate 17 also stops immediately. At this time, the oil flow in the downcomer 6 flows down naturally by gravity. All mechanical actions that may obstruct the flow stop, thus completely avoiding any interference with the unstable liquid seal state and ensuring the stability of the core deodorization process. After the rotating shaft 16 stops rotating, its bottom collection hopper 27 is stationary above the inlet of the downcomer 5.This is used to catch large pieces of impurities that may accidentally fall from the screen 20 or the receiving tube 25, preventing them from falling directly into and clogging the downcomer 5.
