Description

Technical Field

[0001] This invention relates to the field of refining equipment technology, and in particular to an energy-saving edible oil refining device. Background Technology

[0002] Crude oil produced through pressing and solvent extraction processes is generally contaminated with various non-glycerol ester impurities, such as free fatty acids, gums, pigments, off-odor substances, and trace metal ions. These impurities reduce the quality, oxidative stability, and nutritional value of the oil, and are also prone to generating harmful components during long-term storage and high-temperature cooking. Edible oil refining processes, through degumming, deacidification, decolorization, and deodorization, sequentially remove pectin-soluble impurities, free fatty acids, pigments, and volatile off-odor components from the oil, thereby bringing it to the level of a finished edible oil that meets food safety standards.

[0003] In summary, for the decolorization process in edible oil refining, bleaching clay is typically introduced into the decolorization tank in dry powder form. This leads to small clay particles easily becoming airborne and readily removed by the vacuum system. Meanwhile, large clay particles settle too quickly and have low adsorption efficiency, thus affecting the decolorization effect. To address this, current technology uses premixed bleaching clay with a portion of the crude oil before introducing it into the decolorization tank. However, the current premixing tank and decolorization tank are separate units, requiring the bleaching clay slurry to be transported via long-distance pipelines. This easily leads to particle settling and pipeline blockage. Furthermore, the high-temperature slurry experiences significant heat loss during transport, necessitating additional heating, thus increasing energy consumption and equipment investment.

[0004] Therefore, this application provides an energy-saving edible oil refining apparatus to meet the demand. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving edible oil refining device to solve the above-mentioned problems, thereby resolving the issues mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An energy-saving edible oil refining device includes a support frame, a refining tank fixedly connected to the inner wall of the support frame, a discharge pipe fixedly connected to the bottom of the refining tank for discharging a solid-liquid mixture after a decolorization reaction, wherein the solid-liquid mixture includes decolorized oil and waste bleaching clay, a control valve fixedly sleeved on the outer wall of the discharge pipe, an inlet pipe fixedly connected to the top outer wall of the refining tank, and a feed pipe fixedly connected to the outer wall of the top of the refining tank away from the inlet pipe for injecting crude oil into a mixing chamber, where the crude oil mixes with bleaching clay to form a bleaching clay slurry, a partition fixedly connected to the inner wall of the refining tank, a second groove and a third groove respectively formed on the outer surface of the partition for dividing the interior of the refining tank into a mixing chamber and a decolorization chamber, a delivery pipe fixedly connected to the outer wall of the refining tank for injecting crude oil into the decolorization chamber, and a mixing mechanism provided inside the refining tank.

[0008] Optionally, the mixing mechanism includes a motor, the output end of which is fixedly connected to a rotating shaft. An arc-shaped plate is fixedly connected to the inner wall of the rotating shaft. After the clay slurry enters the cavity inside the rotating shaft, the arc-shaped plate rotates synchronously with the shaft as the rotating shaft rotates, pushing the clay slurry in the cavity. This allows the clay slurry to be pushed from inside the rotating shaft towards the connecting pipe and conveyed towards the mixing frame, preventing the slurry from becoming too viscous and stagnating inside the shaft cavity. A second through hole is provided on the outer surface of the rotating shaft near the motor, and a third through hole is provided on the outer surface of the rotating shaft away from the second through hole. A first stirring frame is fixedly connected to the outer surface of the rotating shaft. The first stirring frame is used to stir the crude oil and clay inside the mixing cavity to form a clay slurry.

[0009] Optionally, a connecting frame is fixedly sleeved on the outer surface of the rotating shaft near the first stirring frame, and a first sealing frame is fixedly sleeved on the outer surface of the rotating shaft near the connecting frame, with the first sealing frame rotatably connected to the inner wall of the third groove.

[0010] Optionally, a sealing ring is fixedly connected to the side of the connecting frame away from the rotating shaft. The sealing ring is rotatably connected to the inner wall of the second groove. A fourth through hole is opened on the outer surface of the connecting frame. Multiple fourth through holes are evenly distributed along the circumference of the connecting frame to ensure that the clay slurry can smoothly enter the interior of the rotating shaft.

[0011] Optionally, a hydraulic rod is fixedly connected to the top of the refining tank, a fixed frame is fixedly connected to the output end of the hydraulic rod, a fixed block is fixedly connected to the inner wall of the fixed frame, the fixed block is fixedly connected to the support frame, and a first groove is formed on the inner wall of the fixed block.

[0012] Optionally, a sliding frame is provided inside the rotating shaft, a rotating frame is fixedly connected to the top of the sliding frame, the inner wall of the rotating frame is slidably connected to the inner wall of the second through hole, and a second sealing frame is fixedly connected to the end of the sliding frame away from the rotating frame.

[0013] Optionally, the inner wall of the second sealing frame is slidably connected in the third through hole, the outer surface of the second sealing frame is used to seal the fourth through hole, the rotating frame is rotatably connected in the first groove, and the hydraulic rod drives the sliding frame to move vertically through the fixed frame.

[0014] Optionally, a mixing frame is provided inside the decolorization chamber, and a connecting pipe is fixedly connected to the outer wall of the mixing frame. The end of the connecting pipe away from the mixing frame is fixedly connected to a rotating shaft. A spray head is fixedly connected to the back of the mixing frame, and the spray head is used to spray white clay slurry into the decolorization chamber.

[0015] Optionally, the outer surface of the mixing frame is provided with a vertical part, and an inclined part is provided between adjacent vertical parts. The vertical part is used to disperse the bleaching slurry sprayed from the spray head. After the bleaching slurry is sprayed from the spray head, it first impacts the vertical part of the mixing frame behind it, and the bleaching slurry is fully dispersed under the impact force. The dispersed slurry is guided by the inclined part, so as to spread evenly in the decolorization chamber and effectively improve the decolorization reaction effect.

[0016] Optionally, a second stirring rack is fixedly connected to the bottom of the mixing rack, the second stirring rack being used to mix the bleaching clay slurry with the crude oil in the decolorization chamber.

[0017] Optionally, a fixing rod is fixedly connected to one end of the refining tank near the discharge pipe. The fixing rod is coaxially arranged inside the rotating shaft. When the rotating shaft rotates, an annular gap is formed between the inner wall of the rotating shaft and the outer surface of the fixing rod. The rotational motion of the rotating shaft generates shear force in this annular gap. When the bleaching clay slurry flows through the annular gap, it is subjected to continuous shear force, which makes it difficult for bleaching clay particles to deposit or clump on the inner wall of the rotating shaft. A first through hole is opened at the bottom of the fixing rod, which is used to assist in discharging the decolorized crude oil inside the refining tank to the discharge pipe.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above-mentioned solution, the energy-saving edible oil refining device provided in this application sets up a refining tank, and sets up the mixing chamber and the decolorizing chamber in an upper and lower stack. The hollow rotating shaft is used as the vertical conveying channel for the bleaching clay slurry. Therefore, the bleaching clay slurry prepared in the mixing chamber can be directly conveyed to the decolorizing chamber without the need for external conveying pipelines. This shortens the material conveying distance and effectively avoids problems such as pipeline blockage, heat loss and material leakage caused by long-distance conveying.

[0020] Meanwhile, by setting up a mixing mechanism, the white clay slurry sprayed from the spray head impacts the vertical part of the mixing frame to complete the dispersion, then is guided and diverted by the inclined part, and then sheared and disturbed by the second mixing frame, thereby ensuring that the white clay slurry and crude oil are fully mixed, thus achieving a uniform decolorization reaction.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0041] like Figure 1 and Figure 3 As shown, an embodiment of the present invention provides an energy-saving edible oil refining device, including a support frame 1, a refining tank 2 fixedly connected to the inner wall of the support frame 1, a discharge pipe 21 fixedly connected to the bottom of the refining tank 2, the discharge pipe 21 being used to discharge the solid-liquid mixture after the decolorization reaction, wherein the solid-liquid mixture includes decolorized oil and waste bleaching clay, a control valve 211 fixedly sleeved on the outer wall of the discharge pipe 21, an inlet pipe 26 fixedly connected to the top outer wall of the refining tank 2, the inlet pipe 26 being used to inject crude oil into the mixing chamber 4, the crude oil mixing with bleaching clay in the mixing chamber 4 to form bleaching clay slurry, an inlet pipe 27 fixedly connected to the outer wall of the top of the refining tank 2 on the side away from the inlet pipe 26, the inlet pipe 27 being used to convey bleaching clay powder into the mixing chamber 4, and a partition 23 fixedly connected to the inner wall of the refining tank 2, such as Figure 10 As shown, the outer surface of the partition 23 is provided with a second groove 24 and a third groove 25 respectively. The partition 23 is used to divide the interior of the refining tank 2 into a mixing chamber 4 and a decolorizing chamber 5. By stacking the mixing chamber 4 and the decolorizing chamber 5, the white clay slurry can flow down into the decolorizing chamber 5 along the inner cavity of the rotating shaft 32 after it is prepared in the mixing chamber 4. This reduces the flow path and eliminates the need for external pipes, solving the problems of blockage, heat loss and leakage caused by long-distance transportation. The outer wall of the refining tank 2 is fixedly connected to a liquid delivery pipe 28, which is used to inject crude oil into the decolorizing chamber 5. The interior of the refining tank 2 is provided with a mixing mechanism 3.

[0042] In this embodiment, as Figure 3As shown, a fixing rod 210 is fixedly connected to one end of the refining tank 2 near the discharge pipe 21. The fixing rod 210 is coaxially arranged inside the rotating shaft 32. When the rotating shaft 32 rotates, an annular gap is formed between the inner wall of the rotating shaft 32 and the outer surface of the fixing rod 210. The rotational motion of the rotating shaft 32 generates shear force in this annular gap. When the bleaching clay slurry flows through the annular gap, it is subjected to continuous shear force, which makes it difficult for bleaching clay particles to deposit or clump on the inner wall of the rotating shaft 32. At the same time, the setting of the fixing rod 210 reduces the radial dimension inside the rotating shaft 32, thereby increasing the flow velocity in the annular gap, reducing the possibility of particle settling and wall adhesion, and ensuring that the bleaching clay slurry can be transported from the mixing chamber 4 to the decolorizing chamber 5. A first through hole 29 is opened at the bottom of the fixing rod 210. The fixing rod 210 is used to assist in discharging the decolorized crude oil inside the refining tank 2 to the discharge pipe 21.

[0043] Because the clay and some oil are fully mixed in the mixing chamber 4 to form a uniform clay slurry, it is then sent to the decolorization chamber 5 for crude oil decolorization reaction. This can improve the utilization rate of clay materials, reduce the amount of clay added, and also reduce the amount of waste clay filter cake generated in the subsequent filtration process.

[0044] Therefore, by setting up a mixing mechanism 3, such as Figure 4 and Figure 8 As shown, the mixing mechanism 3 includes a motor 31, the output end of which is fixedly connected to a rotating shaft 32. The rotating shaft 32 is a hollow shaft structure, forming a vertical conveying channel for the bleaching slurry inside. An arc-shaped plate 325 is fixedly connected to the inner wall of the rotating shaft 32. When the bleaching slurry enters the cavity inside the rotating shaft 32, the arc-shaped plate 325 rotates synchronously with the shaft as the rotating shaft 32 rotates, pushing the bleaching slurry in the cavity. This allows the bleaching slurry to be pushed from inside the rotating shaft 32 toward the connecting pipe 351 and conveyed toward the mixing frame 35, preventing the slurry from being transported to the mixing frame 35. The liquid viscosity is too high and stagnation occurs inside the shaft cavity. A second through hole 321 is opened on the outer surface of the rotating shaft 32 near the motor 31, and a third through hole 324 is opened on the outer surface of the rotating shaft 32 away from the second through hole 321. A first stirring frame 322 is fixedly connected to the outer surface of the rotating shaft 32. When the rotating shaft 32 drives the first stirring frame 322 to rotate, the first stirring frame 322 pushes the liquid in the mixing chamber 4 to flow, so that the clay powder and crude oil come into contact and disperse in the mixing chamber 4. The surface of the clay particles is wetted by oil, thereby forming a uniform clay slurry.

[0045] A connecting frame 33 is fixedly sleeved on the outer surface of the rotating shaft 32 near the first stirring frame 322, and a first sealing frame 323 is fixedly sleeved on the outer surface of the rotating shaft 32 near the connecting frame 33. The first sealing frame 323 is rotatably connected to the inner wall of the third groove 25.

[0046] A sealing ring 332 is fixedly connected to the side of the connecting frame 33 away from the rotating shaft 32. The first sealing frame 323 and the sealing ring 332 are respectively set in the third groove 25 and the second groove 24 to form a seal between the rotating shaft 32 and the partition plate 23. The sealing ring 332 is rotatably connected to the inner wall of the second groove 24. A fourth through hole 331 is opened on the outer surface of the connecting frame 33. Multiple fourth through holes 331 are evenly distributed along the circumference of the connecting frame 33 to ensure that the clay slurry can smoothly enter the interior of the rotating shaft 32.

[0047] like Figure 8 As shown, a hydraulic rod 22 is fixedly connected to the top of the refining tank 2, and a fixed frame 221 is fixedly connected to the output end of the hydraulic rod 22. A fixed block 222 is fixedly connected to the inner wall of the fixed frame 221. The fixed block 222 is fixedly connected to the support frame 1, and a first groove 223 is provided on the inner wall of the fixed block 222.

[0048] like Figure 11 As shown, a sliding frame 34 is provided inside the rotating shaft 32. A rotating frame 342 is fixedly connected to the top of the sliding frame 34. The inner wall of the rotating frame 342 is slidably connected to the inner wall of the second through hole 321. Therefore, the rotating frame 342 rotates synchronously with the rotating shaft 32. A second sealing frame 341 is fixedly connected to the end of the sliding frame 34 away from the rotating frame 342.

[0049] The inner wall of the second sealing frame 341 is slidably connected in the third through hole 324. The outer surface of the second sealing frame 341 is used to seal the fourth through hole 331. The rotating frame 342 is rotatably connected in the first groove 223. The hydraulic rod 22 drives the sliding frame 34 to move vertically through the fixed frame 221. When the hydraulic rod 22 drives the sliding frame 34 to move downward, the second sealing frame 341 disengages from the corresponding position of the fourth through hole 331. When the fourth through hole 331 is fully opened, the clay slurry inside the mixing chamber 4 can flow into the rotating shaft 32 through the fourth through hole 331.

[0050] like Figure 9As shown, a mixing frame 35 is installed inside the decolorization chamber 5. A connecting pipe 351 is fixedly connected to the outer wall of the mixing frame 35. The end of the connecting pipe 351 away from the mixing frame 35 is fixedly connected to the rotating shaft 32. A spray head 352 is fixedly connected to the back of the mixing frame 35. The spray head 352 is used to spray white clay slurry into the decolorization chamber 5. It is worth noting that a vertical part 354 is provided on the outer surface of the mixing frame 35, and an inclined part 355 is provided between adjacent vertical parts 354. A second stirring frame 353 is fixedly connected to the bottom of the mixing frame 35 and rotates together with the mixing frame 35 driven by the rotating shaft 32. The second stirring frame 353 is used to mix the white clay slurry with the crude oil in the decolorization chamber 5. When the white clay slurry is sprayed from the spray head 352, the white clay slurry first impacts the vertical part 354 of the mixing frame 35 behind it. The white clay slurry is fully dispersed under the impact force. The dispersed slurry is guided by the inclined part 355, thereby spreading evenly in the decolorization chamber 5 and effectively improving the decolorization reaction effect. At the same time, the rotation of the second stirring rack 353 disturbs the slurry, further promoting the more uniform dispersion of the clay slurry in the decolorization chamber 5, so that it can fully contact and blend with the oil materials.

[0051] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
