Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, and more specifically, to an oil crystallization filtration device. Background Technology

[0002] The crystallization and filtration process of conjugated linoleic acid and conjugated linoleic acid glycerides is a core method for achieving high-purity purification by inducing crystal precipitation at low temperature combined with specific separation techniques.

[0003] In the process of crystallization filtration, the oil needs to be heated first to remove moisture and low-boiling-point substances, and then cooled to promote the selective crystallization of the target isomers. However, due to the high viscosity of the oil, it is difficult to be heated and cooled quickly and evenly during processing, resulting in low crystallization efficiency. In addition, the viscous liquid oil is filtered out slowly during filtration. Therefore, a high-efficiency oil crystallization filtration device is needed to improve the heating and cooling rate of the oil, so that oil crystals can be generated more quickly and the filtration rate of oil crystals can be increased to ensure production efficiency. Utility Model Content

[0004] This invention provides an oil crystallization filtration device, which solves the technical problems in the prior art where viscous oil is difficult to cool quickly and evenly, resulting in low oil crystallization efficiency and slow filtration speed of viscous liquid oil when filtering oil crystals.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: An oil crystallization and filtration device includes a crystallization tank. A temperature control tube with a spiral structure is installed inside the crystallization tank, with its top and bottom ends extending outwards from the outside of the crystallization tank. A three-way valve is connected to the top of the temperature control tube, with its two inlets connected to a cold air pipe and a hot air pipe, respectively. A first motor is fixedly installed at the top of the crystallization tank, with its output shaft extending into the crystallization tank and connected to a stirring shaft. A discharge pipe is connected to the bottom of the crystallization tank, and a solenoid valve is installed on the discharge pipe. The device also includes a collection bucket, with a filter screen sleeve rotatably connected inside each collection bucket. A drive assembly for controlling the rotation of the filter screen sleeve is provided between the top of the collection bucket and the filter screen sleeve.

[0006] Furthermore, the drive assembly includes a second motor fixedly mounted on the top of the collection bucket, a gear connected to one end of the output shaft of the second motor, and a gear ring connected around the filter screen and meshing with the second motor.

[0007] Furthermore, a temperature sensor and a display screen are installed on the crystallization tank.

[0008] Furthermore, the outer wall of the crystallization tank is provided with a heat-insulating interlayer.

[0010] Furthermore, the crystallization tank is connected to support legs on both sides, and the collection bucket is equipped with casters inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the heating and cooling effect of the spiral temperature control tube on the oil inside the crystallization tank, and the stirring effect of the stirring shaft on the oil inside the crystallization tank, can enable the oil inside the crystallization tank to be heated or cooled quickly and evenly, effectively improving the formation efficiency of oil crystallization. In addition, when the oil crystals enter the filter screen, the drive component can make the filter screen rotate, so that the oil crystals inside are subjected to centrifugal force. Under this action, the liquid oil can be quickly filtered out from the filter screen, thereby effectively improving the 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.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. 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.

[0017] Please see Figure 1-4A grease crystallization filtration device includes a crystallization tank 1. A temperature control tube 2, made of copper, is installed inside the crystallization tank 1. The temperature control tube 2 has good thermal conductivity, allowing cold or hot air to pass through it, thus heating or cooling the grease inside the crystallization tank 1. The temperature control tube 2 has a spiral structure, increasing its effective length inside the crystallization tank 1, enabling sufficient heat exchange with the grease. The top and bottom of the temperature control tube 2 extend outside the crystallization tank 1. A three-way valve 3 is connected to the top of the temperature control tube 2, with its two inlets connected to a cold air pipe and a hot air pipe, respectively. Therefore, by controlling the three-way valve 3, cold or hot air can enter the temperature control tube 2, thereby heating or cooling the grease inside the crystallization tank 1. A first motor 4 is fixedly installed at the top of the crystallization tank 1. The output shaft of the first motor 4 extends into the crystallization tank 1 and is connected to a stirring shaft 5. When the first motor 4 drives the stirring shaft 5 to rotate, it stirs the grease inside the crystallization tank 1, thus making the grease more resistant to heat. To achieve uniform heating or cooling, a discharge pipe 6 is connected to the bottom of the crystallization tank 1, and a solenoid valve 7 is installed on the discharge pipe 6. After the grease crystallizes inside the crystallization tank 1, the solenoid valve 7 can be opened to allow the grease crystals to be discharged to the outside of the crystallization tank 1 through the discharge pipe 6. The device also includes a set of collection buckets 8, and a filter screen sleeve 9 is rotatably connected inside the collection bucket 8. When the collection bucket 8 is placed below the crystallization tank 1, the grease crystals discharged from the discharge pipe 6 can fall into the filter screen sleeve 9. Through the filtration of the filter screen sleeve 9, the solid grease is intercepted in the filter screen sleeve 9, while the liquid grease flows through the filter screen sleeve 9 to the bottom of the collection bucket 8 and flows out from the discharge pipe at the bottom of the collection bucket 8, thus achieving the filtration and separation of grease crystals. A drive component is set between the top of the collection bucket 8 and the filter screen sleeve 9. The drive component can drive the filter screen sleeve 9 to rotate. When the filter screen sleeve 9 rotates, the grease crystals falling into the filter screen sleeve 9 are subjected to centrifugal force, which can filter out the liquid grease more quickly.

[0018] The grease to be processed is injected into the crystallization tank 1. The three-way valve 3 at the top of the temperature control pipe 2 connects the temperature control pipe 2 to the hot air pipe. Hot air then flows through the temperature control pipe 2, exchanging heat with the grease inside the crystallization tank 1 to heat it. When the grease reaches the designed temperature range, the three-way valve 3 connects the temperature control pipe 2 to the cold air pipe, cooling the grease inside the crystallization tank 1 and causing it to crystallize. During this process, because the temperature control pipe 2 is spirally distributed inside the crystallization tank 1, it can fully exchange heat with the crystallization tank 1. While the grease is being heated or cooled, the first motor 4 drives the stirring shaft 5 to rotate, which stirs the grease, allowing the grease inside the crystallization tank 1 to be heated or cooled quickly and evenly, effectively improving the efficiency of grease crystal formation. In addition, the generated grease crystals flow into the filter screen sleeve 9 on the collection tank 8 through the discharge pipe 6. The filter screen sleeve 9 rotates under the action of the drive component, causing the grease crystals inside to be subjected to centrifugal force, allowing the liquid grease to be quickly filtered out from the filter screen sleeve 9 and flow out through the discharge pipe at the bottom of the filter screen sleeve 9, while the solid grease crystals remain in the filter screen sleeve 9, effectively improving the processing efficiency.

[0019] For further details, please refer to Figure 1-4 The drive assembly includes a second motor 10 fixedly mounted on the top of the collection bucket 8, a gear 11 connected to one end of the output shaft of the second motor 10, and a gear ring 12 connected around the filter screen sleeve 9 and meshing with the second motor 10. When the second motor 10 drives the gear 11 to rotate, the gear 11 will drive the gear ring 12 meshing with it to rotate, thereby causing the filter screen sleeve 9 to rotate under the drive of the gear ring 12.

[0020] For further details, please refer to Figure 1-4 A thermometer 13 is installed on the crystallization tank 1. The temperature probe of the thermometer 13 extends into the interior of the crystallization tank 1 to monitor the temperature of the oil inside the crystallization tank 1. A display screen 14 is installed on the crystallization tank 1 to display the temperature data monitored by the thermometer 13, which is convenient for staff to view and control.

[0021] For further details, please refer to Figure 1-4 The outer wall of the crystallization tank 1 is equipped with a heat-insulating jacket, which can keep the inside of the crystallization tank 1 warm and prevent heat exchange between the crystallization tank 1 and the external environment, so that the oil can crystallize in a suitable temperature environment.

[0022] For further details, please refer to Figure 1-4A sampling tube 15 is connected to one side of the crystallization tank 1. A valve 16 is installed on the sampling tube 15. After opening the valve 16, the oil inside the crystallization tank 1 can be sampled through the sampling tube 15, so that people can understand the degree of crystallization of the oil inside the crystallization tank 1.

[0023] For further details, please refer to Figure 1-4 The crystallization tank 1 is connected to two support legs 17 on both sides, which can provide stable support for the crystallization tank 1 as a whole. The collection bucket 8 is equipped with casters 18 inside, which facilitates the movement of the collection bucket 8.

[0024] 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.
