Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation devices, and in particular to an oil-water separation device for edible oil production. Background Art

[0002] Oil-water separation is a crucial step in edible oil production, with its efficiency and quality directly impacting both the quality and production cost of the oil. Traditional oil-water separation methods face numerous challenges and struggle to meet the growing demand for efficiency in modern edible oil production.

[0003] Early gravity sedimentation methods, while simple to use, relied on the natural separation of oil and water, resulting in extremely slow separation. This not only consumed significant time and extended production cycles, but also required significant space for the sedimentation equipment, increasing site costs. Furthermore, for some highly emulsified oil-water mixtures, gravity sedimentation alone proved difficult to achieve complete separation, resulting in a significant amount of water remaining in the separated edible oil, compromising oil quality.

[0004] While centrifugal separation offers speed improvements over gravity sedimentation, it also requires complex equipment and consumes significant energy. The high-speed operation of the centrifuge consumes significant amounts of electricity, increasing production costs. Furthermore, centrifuges require high maintenance. Frequent maintenance not only increases labor costs but can also cause production halts due to equipment failures, impacting productivity. Furthermore, centrifugal separation is limited in its ability to remove fine oil droplets and impurities, making it ineffective for high-quality edible oil production. Summary of the Invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A specific structure of an oil-water separation device for edible oil production includes a first heating barrel, a separation mechanism is fixedly installed on the side wall of the first heating barrel, the separation mechanism includes a second heating barrel, the second heating barrel is fixedly installed on the side wall of the first heating barrel, a first connecting pipe is fixedly installed on the top of the second heating barrel, a first rotating shaft is rotatably installed on the top of the second heating barrel, a first rotating fan blade is fixedly installed on the side wall of the first rotating shaft, a synchronous belt transmission assembly is driven and installed on the side wall of the first rotating shaft, a second rotating fan blade is fixedly installed on the side wall of the synchronous belt transmission assembly away from the first rotating shaft, a rotating stirring shaft is fixedly installed on the side wall of the second rotating shaft, a wedge-shaped circular plate is rotatably installed on the side wall of the second rotating shaft, and a cylindrical connecting barrel is fixedly installed on the top of the wedge-shaped circular plate.

[0008] In a possible implementation, the synchronous belt transmission assembly is located at the upper end of the first rotating shaft, and the rotating stirring shaft is located below the second rotating fan blade.

[0009] In a possible implementation, the side wall of the cylindrical connecting barrel is fixedly mounted to the interior of the first heating barrel, and a concave disc is fixedly mounted inside the first heating barrel.

[0010] In a possible implementation, the second rotating shaft is rotatably mounted inside the concave disc, and a hollow cylinder is fixedly mounted on the top of the second heating barrel.

[0011] In a possible implementation, the first rotating fan blade is located inside the hollow cylinder, and the end of the first connecting tube away from the second heating barrel is fixedly mounted to the hollow cylinder.

[0012] In a possible implementation, the first rotating shaft is rotatably mounted inside the hollow cylinder, and a second connecting pipe is fixedly mounted on a side wall of the hollow cylinder.

[0013] In a possible implementation, the second connecting pipe is located on the left side of the first connecting pipe, and one end of the second connecting pipe away from the hollow cylinder is fixedly installed on the second heating barrel, and a one-way valve is fixedly installed inside the second heating barrel.

[0014] In a possible implementation, an electromagnetic circulation valve is fixedly installed on the bottom of the first heating barrel, and a first output pipe is fixedly installed on the side wall of the first heating barrel.

[0015] In a possible implementation, a threaded rotating plug is installed on the inner thread of the first output tube, and a second output tube is fixedly installed on the side wall of the first heating barrel.

[0016] In a possible implementation, the second output pipe is fixedly mounted on the side wall of the cylindrical connecting barrel, the second output pipe is fixedly mounted inside the first heating barrel, and a connecting base is fixedly mounted on the side walls of the first heating barrel and the second heating barrel.

[0017] Beneficial effects compared with existing technologies:

[0018] 1. In this solution, the device achieves efficient oil-water separation through a variety of ingenious designs, greatly improving production efficiency. First, the use of chitosan flocculant causes oil and water droplets to aggregate, creating a favorable starting point for oil-water separation. At the same time, the rotating stirring shaft, driven by the second shaft, stirs the oil, water and flocculant. This not only allows the flocculant to mix more thoroughly with the oil and water, accelerating the separation process of water and oil, but also increases the contact area between the oil, water and air. In addition, the first heating barrel continuously heats the oil, utilizing the difference in boiling points between water and oil to cause the water to evaporate first. This synergistic effect of stirring and heating greatly increases the speed of oil-water separation. In addition, a series of steam-driven components work together, from steam driving the first rotating fan blades to drive the first rotating shaft to the synchronous belt drive assembly to drive the second rotating shaft and related components. The entire process works closely together, making the oil-water separation process efficient and orderly. Compared with traditional oil-water separation methods, the separation task can be completed in a shorter time, meeting the demand for efficient production in the edible oil production process.

[0019] 2. In this solution, this device has significant advantages in energy utilization and effectively reduces energy consumption. When the first heating barrel is heated, the heat is transferred to the second heating barrel, causing the water therein to evaporate and generate steam. Part of this steam drives the first rotating fan blades and other components to move, realizing the conversion of mechanical energy and being used for separation operations such as stirring, while the other part of the steam is liquefied at a specific position, that is, near the concave disc, due to the cold air generated by the concave disc and returns to the inside of the first heating barrel. This process realizes the recycling of steam and avoids the waste of steam energy. Through this energy recycling method, the dependence on external energy is reduced, and the energy consumption of the entire oil-water separation process is reduced. For edible oil production companies, long-term operation can save a lot of energy costs. At the same time, it is also in line with the current development trend of energy conservation and environmental protection, and has good economic and environmental benefits.

[0020] 3. In this solution, from feeding to separation to discharging, each link is closely connected, ensuring the oil-water separation effect and the stability of the device operation. During feeding, the first output pipe is opened as the feeding channel by rotating the threaded rotary plug, which can precisely control the addition of raw materials. During the separation process, various components cooperate with each other. For example, the one-way valve ensures the flow of steam, allowing steam to effectively drive the first rotating fan and other components, providing power for subsequent separation operations. The concave disc cooperates with other components to achieve steam liquefaction and water diversion, ensuring that the water can be smoothly separated and discharged from the oil-water mixture. Finally, the outflow of residual oil and sediment is controlled by the electromagnetic flow valve at the bottom, and screening is carried out using tools such as filters and sieve plates to further ensure the complete separation of oil and water. In addition, the fixed connection between each component, such as the tight connection between the first and second heating barrels through the side walls, and the connection between each rotating shaft and related components, all ensure the stability of the device during operation, reduce the occurrence of failures caused by loose components, ensure long-term stable oil-water separation effect, and provide reliable protection for edible oil production.

[0029] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, and therefore the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not related to the present invention will be omitted from the drawings.

[0030] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0031] Example:

[0032] Please refer to Figure 1 and Figure 6 As shown, this embodiment introduces a specific structure of an oil-water separation device for edible oil production, including a first heating barrel 11, counterclockwise rotating the threaded rotary plug 28, unscrewing the threaded rotary plug 28 out of the first output pipe 27, and then pouring the oil, water and chitosan flocculant into the first heating barrel 11 to heat the first heating barrel 11. The side wall of the first heating barrel 11 is fixedly mounted with a second heating barrel 12, and the first heating barrel 11 transfers heat to the second heating barrel 12. A first connecting pipe 13 is fixedly mounted on the top of the second heating barrel 12, and the water inside the second heating barrel 12 will be evaporated, and the steam inside the second heating barrel 12 will be transmitted to the first connecting pipe 13. A first rotating shaft 14 is rotatably mounted on the top of the second heating barrel 12. Due to the one-way valve inside the second connecting pipe 25, the steam will not be able to enter the second connecting pipe 25, and a large amount of steam will enter the hollow cylinder 24. The steam will push the first rotating fan blade 15 to rotate counterclockwise, and the first rotating fan blade 15 drives the first rotating shaft 14 to rotate counterclockwise.

[0033] The first rotating fan blade 15 is fixedly installed on the side wall of the first rotating shaft 14, and the steam is then transmitted from the hollow cylinder 24 to the inside of the hollow cylinder 24. The hollow cylinder 24 is close to the concave disc 23. When the concave disc 23 generates cold air, the steam inside the second connecting pipe 25 is liquefied and returned to the inside of the first heating barrel 11. The side wall of the first rotating shaft 14 is driven by a synchronous belt transmission assembly 16. The first rotating shaft 14 drives the synchronous belt transmission assembly 16 to rotate counterclockwise. The synchronous belt transmission assembly 16 is located at the first rotating shaft 14. At the upper end, a second rotating shaft 17 is installed on the end of the synchronous belt transmission assembly 16 away from the first rotating shaft 14. The synchronous belt transmission assembly 16 drives the second rotating shaft 17 to rotate counterclockwise. A second rotating fan blade 18 is fixedly installed on the side wall of the second rotating shaft 17. The second rotating shaft 17 drives the rotating stirring shaft 19 to rotate counterclockwise. The rotating stirring shaft 19 will stir the oil, water and flocculant to accelerate the separation of water and oil. At the same time, the first heating barrel 11 heats the oil and water. Due to the difference in boiling points, the water will be evaporated first.

[0034] A rotating stirring shaft 19 is fixedly installed on the side wall of the second rotating shaft 17. The rotating stirring shaft 19 is located below the second rotating blade 18. The rotating stirring shaft 19 rotates in a counterclockwise circular motion to stir the oil and water, which will increase the contact area between the oil and water and the air, and will accelerate the evaporation of the oil and water. The generated steam will be quickly blown to the concave disc 23 by the second rotating blade 18, and the cold air of the concave disc 23 will quickly liquefy the water. A wedge-shaped circular plate 21 is rotatably installed on the side wall of the second rotating shaft 17. The liquefied water will gather along the concave disc 23 to the side wall of the second rotating shaft 17, and then flow along the second rotating shaft 17 to the inside of the cylindrical connecting barrel 22. A cylindrical connecting barrel 22 is fixedly installed on the top of the wedge-shaped circular plate 21. Bucket 22, the side wall of the cylindrical connecting barrel 22 is fixedly installed inside the first heating barrel 11, and the water inside the cylindrical connecting barrel 22 will flow along the wedge-shaped circular plate 21 to the inside of the second output pipe 29, and then flow out of the cylindrical connecting barrel 22 through the second output pipe 29. A concave disc 23 is fixedly installed inside the first heating barrel 11, and the second rotating shaft 17 is rotatably installed inside the concave disc 23. A hollow cylinder 24 is fixedly installed on the top of the second heating barrel 12, and the first rotating fan blade 15 is located inside the hollow cylinder 24. The end of the first connecting pipe 13 away from the second heating barrel 12 is fixedly installed with the hollow cylinder 24, and the first rotating shaft 14 is rotatably installed inside the hollow cylinder 24;

[0035] A second connecting pipe 25 is fixedly installed on the side wall of the hollow cylinder 24, and the second connecting pipe 25 is located on the left side of the first connecting pipe 13. The end of the second connecting pipe 25 away from the hollow cylinder 24 is fixedly installed on the second heating barrel 12, and a one-way valve is fixedly installed inside the second heating barrel 12. An electromagnetic circulation valve 26 is fixedly installed at the bottom of the first heating barrel 11. The remaining oil and sediment will flow out of the first heating barrel 11 from the electromagnetic circulation valve 26, and then the oil and water sediment will be screened to completely separate the oil and water. A first output pipe 27 is fixedly installed on the side wall of the first heating barrel 11, and a threaded rotary plug 28 is threadedly installed inside the first output pipe 27. A second output pipe 29 is fixedly installed on the side wall of the first heating barrel 11, and the second output pipe 29 is fixedly installed on the side wall of the cylindrical connecting barrel 22. The second output pipe 29 is fixedly installed inside the first heating barrel 11, and a connecting base 31 is fixedly installed on the side walls of the first heating barrel 11 and the second heating barrel 12.

[0036] Working principle: First, the operator rotates the threaded rotary plug 28 counterclockwise. With the characteristics of the threaded structure, the threaded rotary plug 28 is gradually unscrewed from the inside of the first output tube 27. The first output tube 27 serves as a channel connecting the outside and the first heating barrel 11. The unscrewing of the threaded rotary plug 28 allows this channel to be unobstructed, thereby successfully opening the feed channel of the first heating barrel 11. After that, the oil-water mixture that has been preliminarily treated or collected and an appropriate amount of chitosan flocculant are slowly and evenly poured into the inside of the first heating barrel 11 according to specific proportion requirements. The chitosan flocculant is selected because it is a natural polymer flocculant with good biocompatibility and flocculation properties, which can promote the oil in the subsequent process. The oil droplets and water droplets approach each other and gather, creating favorable conditions for oil-water separation. After the raw materials are added, the heating operation for the first heating barrel 11 is started. This step is crucial because the energy provided by the heating is the basic driving force for the smooth progress of the entire separation process. The heating method may adopt various forms such as electric heating and gas heating. Regardless of which method is used, the purpose is to gradually increase the temperature inside the first heating barrel 11 and provide energy support for a series of subsequent physical changes. Since the first heating barrel 11 and the second heating barrel 12 are tightly fixedly connected by the side wall, during the heating process of the first heating barrel 11, the heat will follow the basic principle of heat transfer and transfer from the high-temperature area of ​​the first heating barrel 11 to the low-temperature area of ​​the second heating barrel 12;

[0037] This heat transfer method may be mainly heat conduction, that is, energy is transferred through the thermal motion of microscopic particles of matter in close contact between the two barrel walls. An appropriate amount of water is pre-injected into the second heating barrel 12. As heat is continuously introduced, the water absorbs energy and the molecular thermal motion intensifies. When the boiling point of water is reached, the water begins to evaporate due to heat, and the liquid water gradually turns into gaseous steam. These steams have high internal energy and fluidity. They are transmitted through the first connecting pipe 13 fixedly installed on the top of the second heating barrel 12. The design and installation of the first connecting pipe 13 ensure that the steam can flow smoothly from the second heating barrel 12 to a specific area. At the same time, a first rotating shaft 14 is rotatably installed on the top of the second heating barrel 12. One end of the second connecting pipe 25 is connected to the hollow cylinder 24, and the other end is connected to the second heating barrel 12 and a one-way valve is installed inside. The structural characteristics of the one-way valve determine that it only allows the fluid to flow in one direction. In this device, it effectively prevents steam from entering the second connecting pipe 25 in the opposite direction, so that a large amount of steam can only enter the hollow cylinder 24 along a predetermined path.

[0038] This ingenious design ensures that the direction of the steam flow is controllable, laying the foundation for the subsequent use of the energy of steam to drive the movement of components. The steam entering the hollow cylinder 24 drives the first rotating blade 15 located therein to rotate counterclockwise by virtue of its own kinetic energy and pressure. The first rotating blade 15 and the first rotating shaft 14 are firmly fixedly connected, such as by welding or key connection, so that the first rotating blade 15 can drive the first rotating shaft 14 to rotate counterclockwise under the action of steam. The first rotating blade 15 is fixedly installed on the side wall of the first rotating shaft 14. The steam does not flow disorderly in the hollow cylinder 24, and some steam flows out of the hollow cylinder 24. The cylinder 24 is transferred to a position close to the concave disc 23. The concave disc 23 may generate cold air through a special refrigeration device or heat exchange with a low-temperature medium. When the steam contacts this low-temperature area, the water molecules in the steam are cooled, the molecular thermal motion slows down, and the distance between them decreases. The gaseous steam gradually liquefies into liquid water. Under the action of gravity, the liquefied water flows along the surface of the relevant components and returns to the interior of the first heating barrel 11. This process not only realizes the recycling of steam and reduces energy waste, but also plays a certain role in regulating the steam pressure and temperature in the entire device, ensuring the stable operation of the device.

[0039] The first rotating shaft 14 is provided with a synchronous belt transmission assembly 16 on the side wall thereof. The synchronous belt transmission assembly 16 is composed of a synchronous belt, a pulley and other components. The working principle is based on the meshing transmission between the synchronous belt and the pulley. The rotation of the first rotating shaft 14 drives the active pulley in the synchronous belt transmission assembly 16 to rotate, and then drives the driven pulley to rotate through the friction force of the synchronous belt, so that the synchronous belt transmission assembly 16 rotates counterclockwise as a whole. The synchronous belt transmission assembly 16 is located at the upper end of the first rotating shaft 14, and the end thereof away from the first rotating shaft 14 is transmission-connected to the second rotating shaft 17. This connection method enables the movement of the synchronous belt transmission assembly 16 to be accurately transmitted to the second rotating shaft 17, thereby driving the second rotating shaft 17 to rotate counterclockwise, and the second rotating shaft 17 is rotated counterclockwise. A second rotating blade 18 and a rotating stirring shaft 19 are fixedly mounted on the side wall of the shaft 17. The rotating stirring shaft 19 is located below the second rotating blade 18. The rotation of the second rotating shaft 17 drives the rotating stirring shaft 19 to rotate counterclockwise. The rotating stirring shaft 19 extends into the oil-water and flocculant mixture system located in the first heating barrel 11 for stirring. On the one hand, the chitosan flocculant can be more fully mixed with the oil and water under the action of stirring. The active groups on its molecular chain interact with the charges on the surfaces of the oil droplets and water droplets, prompting the oil droplets and water droplets to aggregate with each other, thereby accelerating the separation process of water and oil. On the other hand, the stirring action of the rotating stirring shaft 19 makes the flow state of the oil-water mixture more complex, thereby increasing the contact area between the oil, water and air.

[0040] At the same time, the first heating barrel 11 continues to heat the oil and water, taking advantage of the difference in boiling points between water and oil. The boiling point of water is relatively low, and it reaches the boiling point first and starts to evaporate during the heating process. The synergistic effect of this stirring and heating greatly improves the efficiency of oil-water separation. After the rotating stirring shaft 19 stirs to accelerate the evaporation of oil and water, the generated steam has a certain speed and direction, and is quickly blown to the concave disc 23 by the second rotating fan blade 18. The design parameters of the second rotating fan blade 18, such as the shape, angle and rotation speed, determine that it can effectively change the flow direction of the steam and give the steam The steam is thrusted toward the concave disc 23 by a certain force. The cold air generated by the concave disc 23 causes the steam to liquefy rapidly. This is based on the physical principle that steam liquefies when cooled. Under the combined action of gravity and surface tension, the liquefied water gathers along the surface of the concave disc 23 to the side wall of the second rotating shaft 17 that is rotatably connected to the concave disc 23. Because there may be a certain gap or special diversion structure at the connection between the second rotating shaft 17 and the concave disc 23, the water can flow along the second rotating shaft 17 to the interior of the cylindrical connecting barrel 22 fixedly mounted on the top of the wedge-shaped circular plate 21.

[0041] The side wall of the cylindrical connecting barrel 22 is fixedly connected to the interior of the first heating barrel 11. The water entering the cylindrical connecting barrel 22 flows along the inclined surface of the wedge-shaped circular plate 21 under the action of the component force of gravity to the second output pipe 29 fixed to the side wall of the cylindrical connecting barrel 22 and the interior of the first heating barrel 11. The design of the diameter, length and installation angle of the second output pipe 29 ensures that the water can smoothly flow out of the cylindrical connecting barrel 22 through it, realizing the discharge of the separated water and completing the separation process of water from the oil-water mixture. The remaining water in the first heating barrel 11 is mainly The oil and some sediments that have not been completely separated, these remaining substances flow out of the first heating barrel 11 through the electromagnetic circulation valve 26 fixedly installed at the bottom. The electromagnetic circulation valve 26 can be opened and closed by electromagnetic control. The valve is opened at the right time to allow the remaining substances to flow out. After flowing out, the oil and water sediments are screened. This step may use tools such as filters and sieve plates to further separate the oil and sediment based on the differences in physical properties such as oil and sediment particle size and density, thereby completely separating the oil and water and completing the entire oil-water separation process.

[0042] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
