Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, and more specifically, to an apparatus for purifying oils. Background Technology

[0002] During the preparation of conjugated linoleic acid, the mixture needs to be washed and purified with water to remove residual catalysts, unreacted substances and other impurities, so as to improve the quality of the finished product.

[0003] Most existing oil purification methods require mixing oil and water in a washing tank. The washing tank is equipped with a vertical stirring shaft that stirs the oil in one direction. This has a small disturbance effect on the oil-water mixture in the tank. During the stirring process, the oil and water are prone to separate into layers, making it difficult to quickly and thoroughly mix the oil and water evenly, resulting in low purification efficiency. Utility Model Content

[0004] This invention provides a device for purifying oils and fats, which solves the technical problem that the existing technology has a small disturbance effect on the oil-water mixture in the reactor, and the oil and fat are prone to separate into layers with water during the stirring process, resulting in low efficiency of oil purification and processing.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A device for purifying oils includes a tank body. Two sets of rotating shafts are rotatably arranged inside the tank body. Both sets of rotating shafts are horizontally positioned along the axis inside the tank body. Stirring blades are fixedly connected to the surface of each rotating shaft. A motor is fixedly installed at the top of the tank body. One end of the motor's output shaft is connected to a drive shaft. The drive shaft extends downward into the tank body and is located between the ends of the two sets of rotating shafts. A transmission assembly for controlling the reverse rotation of the two sets of rotating shafts is provided between the drive shaft and the two sets of rotating shafts. Electric heating tubes are also installed on both sides of the bottom of the tank body.

[0007] Furthermore, the transmission assembly includes a first bevel gear connected to the bottom end of the drive shaft and two sets of second bevel gears connected to the ends of the two sets of rotating shafts. The two sets of second bevel gears are arranged opposite each other and mesh with the two sides of the first bevel gear respectively.

[0008] Furthermore, a support is fixedly installed inside the tank, one end of the rotating shaft is rotatably connected to the support via a bearing, and the other end of the rotating shaft is rotatably connected to the inner wall of the tank via a bearing.

[0009] Furthermore, the surface of the stirring blade is provided with pressure-reducing holes.

[0010] Furthermore, the tank body is made of stainless steel, and a transparent observation window is provided on the outer wall of the tank body.

[0011] Furthermore, the bottom of the tank is fixedly connected to two support legs, and the bottom of the support legs is provided with positioning holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Since the rotating shaft is horizontally set inside the tank, when it drives the stirring blades to rotate, the stirring blades can turn the water that has sunk to the bottom of the tank to the top and the oil that floats on the top of the tank to the bottom, thereby effectively avoiding the phenomenon of oil stratification during the stirring process. Moreover, through the motor, drive shaft and transmission components, the two sets of rotating shafts can drive the stirring blades to rotate in opposite directions, which increases the disturbance effect on the oil-water mixture inside the tank. Therefore, the oil in the tank can be quickly and fully mixed with water, effectively improving the purification processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A device for purifying oils includes a tank 1, with two sets of rotating shafts 2 rotatably mounted inside the tank 1. The tank 1 has a cylindrical structure, and both sets of rotating shafts 2 are horizontally positioned along the axis inside the tank 1. Stirring blades 3 are fixedly connected to the surfaces of both sets of rotating shafts 2. When the rotating shafts 2 rotate, they drive the stirring blades 3 to rotate inside the tank 1. During this process, the stirring blades 3 can stir the oil-water mixture in the tank 1. A motor 5 is fixedly installed at the top of the tank 1, and one end of the output shaft of the motor 5 is connected to a drive shaft 6. The drive shaft 6 extends downward into the interior of the tank 1 and is located between the ends of the two sets of rotating shafts 2. In addition, a transmission assembly is provided between the drive shaft 6 and the two sets of rotating shafts 2. When the motor 5 drives the drive shaft 6 to rotate, the transmission assembly can generate a reverse rotational driving force on the two sets of rotating shafts 2, thereby controlling the two sets of rotating shafts 2 to rotate in opposite directions at the same time. This allows the stirring blades 3 on the two sets of rotating shafts 2 to stir the oil-water mixture in the tank 1 in opposite directions. Electric heating tubes 7 are also installed on both sides of the bottom of the tank 1 for heating the grease inside the tank 1.

[0022] After the grease and water are injected into the tank 1, the motor 5 is started, which drives the drive shaft 6 to rotate. The drive shaft 6, through a transmission assembly, drives two sets of rotating shafts 2 to rotate in opposite directions simultaneously. These two sets of rotating shafts 2 drive the stirring blades 3 on them to stir the grease inside the tank 1 in opposite directions, allowing the grease to mix with the water. At the same time, the electric heating element 7 is turned on to heat the grease inside the tank 1. Under the combined effects of heating and stirring, impurities in the grease dissolve into the water. Finally, the motor 5 is turned off, allowing the contents of the tank 1 to return to normal. The oil and water are allowed to separate into layers. After the water in the lower layer is extracted, impurities in the oil can be removed. Since the rotating shaft 2 is horizontally set inside the tank 1, when it drives the stirring blade 3 to rotate, the stirring blade 3 can turn the water that has settled at the bottom of the tank 1 to the top and the oil that has floated on the top of the tank 1 to the bottom. This effectively prevents the oil from separating during the stirring process. In addition, the two sets of rotating shafts 2 drive the stirring blades 3 to rotate in opposite directions, which can increase the disturbance effect on the oil-water mixture inside the tank 1. Therefore, the oil in the tank 1 can be quickly and fully mixed with the water, which effectively improves the purification efficiency.

[0023] For further details, please refer to Figure 1-4 The transmission assembly includes a first bevel gear 8 connected to the bottom end of the drive shaft 6 and two sets of second bevel gears 9 connected to the ends of two sets of rotating shafts 2. The two sets of second bevel gears 9 are arranged opposite each other and mesh with the two sides of the first bevel gear 8 respectively. When the drive shaft 6 drives the first bevel gear 8 to rotate, the first bevel gear 8 drives the two sets of second bevel gears 9 meshing on its two sides to rotate in the opposite direction, thereby causing the two sets of rotating shafts 2 to rotate in the opposite direction under the drive of the second bevel gears 9.

[0024] For further details, please refer to Figure 1-4 A support 10 is fixedly installed inside the tank body 1. One end of the rotating shaft 2 is rotatably connected to the support 10 through a bearing, and the other end of the rotating shaft 2 is rotatably connected to the inner wall of the tank body 1 through a bearing. The rotating shaft 2 can be stably kept inside the tank body 1 and is not prone to deviation during the rotation of the rotating shaft 2.

[0025] For further details, please refer to Figure 1-4 The surface of the stirring blade 3 is provided with pressure relief holes 11. When the stirring blade 3 rotates and stirs the oil-water mixture inside the tank 1, the pressure relief holes 11 allow some liquid to pass through the stirring blade 3, thereby reducing and dispersing the liquid resistance experienced by the stirring blade 3, and preventing the stirring blade 3 from being deformed or damaged.

[0026] For further details, please refer to Figure 1-4 The tank body 1 is made of stainless steel, which has high strength and corrosion resistance, ensuring its service life. The outer wall of the tank body 1 is equipped with a transparent observation window 12, which allows staff to easily observe the oil purification and processing process inside the tank body 1.

[0027] For further details, please refer to Figure 1-4 The bottom sides of the tank body 1 are fixedly connected with support legs 13 to support the entire tank body 1. The bottom end of the support legs 13 is provided with positioning holes 4. By passing expansion bolts through the positioning holes 4 and nailing them into the ground, the entire tank body 1 can be fixed to ensure the stability of the tank body 1 during use.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
