Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal separation devices, and in particular to a centrifugal separation device for efficient extraction of casein from yak milk. Background Technology
[0002] Centrifugal separators are devices that use high-speed rotation to generate centrifugal force to separate mixed substances. Their core components are drums or rotors. Centrifugal separators for the efficient extraction of casein from yak milk are used because they significantly improve extraction efficiency, reducing the settling time from several hours to just minutes or tens of minutes; they allow for precise parameter control to improve casein purity, meeting the high-purity casein demands of the food and pharmaceutical industries; they can adapt to different scales of production, from small laboratories to large-scale industrial production, and can be integrated with other equipment for streamlined operations; they also allow for precise setting and monitoring of various conditions, ensuring the stability of casein product quality and reducing quality fluctuations caused by environmental factors.
[0003] The existing centrifugal separation device for high-efficiency extraction of casein from yak milk first pre-treats the yak milk by adding an acid solution to adjust the pH value, causing the casein to aggregate into large particles. Then, the mixture is placed in a rotating drum, and the motor drives the drum to rotate at high speed to generate centrifugal force. Under the action of centrifugal force, the larger casein particles move towards the edge or bottom of the drum and are deposited. The liquid part (whey) is thrown out through the small holes in the drum wall due to the smaller centrifugal force. After centrifugation, the liquid is collected through the liquid outlet, and the casein is discharged through the solid outlet. The casein can be further washed and dried to improve its purity. The whole process achieves high-efficiency extraction of casein by utilizing centrifugal force and the differences in the physical properties of the substances.
[0004] However, in the actual application of current centrifugal separation devices for high-efficiency extraction of casein from yak milk, there is a problem. Because they use a single-drum structure, this single drum cannot extract casein from yak milk fully and effectively in one operation. This often results in the need to centrifuge the same yak milk sample multiple times to achieve a relatively ideal level of casein purity and extraction yield. Multiple centrifugations not only greatly increase the time cost of the entire extraction process and consume more energy and human resources, but also significantly reduce the efficiency that the centrifugal separation device for high-efficiency extraction of casein from yak milk should possess. This seriously hinders the further promotion and application of this device in the field of yak casein extraction and is not conducive to the efficient and rapid development of related industries.

[0027] 1. In this utility model, yak milk is first poured into the first drum, then the lid is closed, and then the motor is started to drive the rotating shaft to rotate. The yak milk is first filtered through the first liner in the first drum, and the filtered liquid flows into the second drum. After being filtered through the second liner, it enters the third drum.

This achieves the effect of removing the inner liner for cleaning when there is a lot of casein attached to it, avoiding the problem of poor centrifugal extraction effect caused by excessive casein accumulation in the inner liner during equipment use. This improves the convenience of the centrifugal separation device for efficient extraction of casein from yak milk. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a centrifugal separation device for efficient extraction of casein from yak milk, comprising a tank 1, a rotating shaft 2 rotatably connected to the top of the tank 1 for providing mechanical support for opening and closing the tank lid 3, a tank lid 3 rotatably connected to the outer wall of the rotating shaft 2 for providing a sealed environment and facilitating the pouring out of the centrifuged yak milk, a handle 4 fixedly connected to the top of the tank lid 3, a drive assembly provided at the bottom of the tank 1, a rotating column 5 rotatably connected inside the tank 1 for driving the centrifugal assembly to rotate, and a centrifugal assembly provided on the outer wall of the rotating column 5;
[0037] The centrifugal assembly includes a first drum 8, a second drum 9, and a third drum 10. The bottom of the first drum 8 is fixedly connected to the top of the rotating column 5, and is used to introduce the yak milk filtered by the first centrifugation into the second drum 9. The inside of the second drum 9 is fixedly connected to the outer wall of the rotating column 5, and is used to introduce the yak milk filtered by the second centrifugation into the third drum 10. The inside of the third drum 10 is fixedly connected to the outer wall of the rotating column 5, and is used to introduce the centrifuged and filtered yak milk into the tank 1. The drive assembly includes a motor 6 and a protective shell 7. The outer wall of the motor 6 is fixedly connected to the inside of the protective shell 7, and is used to drive the rotation of the drum. One end of the protective shell 7 is fixedly connected to the bottom of the tank 1, and is used to protect the motor 6. The output end of the motor 6 is connected to the bottom end of the rotating column 5.
[0038] Specifically, during the centrifugation process of yak milk, the operator first holds handle 4 and slowly applies force to open the lid 3 upwards. Then, the prepared yak milk is slowly poured into the first rotating drum 8 along the opening. After all the yak milk has been poured in, the operator slowly closes the lid 3, ensuring a tight seal between the lid 3 and the tank body 1, creating a sealed environment. Subsequently, the motor 6 is started, driving the rotating column 5 to rotate at high speed. The rotation of the rotating column 5 causes the first rotating drum 8 to rotate rapidly as well. During the high-speed rotation of the first rotating drum 8, the yak milk begins to separate under the powerful centrifugal force. In the centrifugation process, a portion of the initially filtered liquid flows slowly into the second drum 9 through a specific guide channel. The milk flowing into the second drum 9 continues to undergo further fine filtration in a high-speed rotating environment. After this round of filtration, the liquid slowly flows into the third drum 10 along a designed flow channel. In the third drum 10, the milk undergoes another rigorous filtration process. Finally, the pure liquid, after being filtered through three drums, flows smoothly into the tank 1. Thus, a complete and orderly centrifugation process is successfully completed, laying a good foundation for subsequent operations such as the extraction of casein from yak milk.
[0039] Reference Figures 2-4The second drum 9 has a second inner liner 12 slidably connected inside, with the second finest pore size, capable of intercepting larger casein molecules. The third drum 10 has a third inner liner 13 slidably connected inside, with the finest pore size, capable of intercepting smaller casein molecules. The first drum 8 has a first inner liner 11 slidably connected inside, with the coarsest pore size, capable of intercepting the largest casein molecules. Multiple sliding blocks 14 are slidably connected to the bottom of the first drum 8 to move the connecting block 15 and the locking block 16. Each sliding block 14 has a connecting block 15 fixedly connected to its top, and a locking block 16 fixedly connected to one side of each connecting block 15 to fix the first inner liner 11. Each sliding block 14 has a sliding post 17 fixedly connected to one end to limit its sliding range. The outer wall of the sliding post 17 is slidably connected inside the first drum 8. A spring 18 is provided at one end to provide support for fixing the locking pin 19. One end of the spring 18 is fixedly connected to one end of the sliding block 14, and the other end of the spring 18 is fixedly connected to the inside of the first drum 8. The locking pin 19 is slidably connected inside the first inner liner 11 to fix the first inner liner 11. A limit plate 20 is fixedly connected to the outer wall of the locking pin 19 to limit the movement range of the locking pin 19. Multiple buttons 21 are slidably connected inside the first drum 8 to unlock the locking pin 19. One end of the button 21 is fixedly connected to a pressing column 22 to move the locking pin 19. A limit plate 23 is fixedly connected to the outer wall of the button 21 to limit the movement range of the button 21. A spring 24 is provided on the outer wall of the pressing column 22 to provide rebound force for the button 21. One end of the spring 24 is fixedly connected to one end of the button 21, and the other end of the spring 24 is fixedly connected to the inside of the first drum 8.
[0040] Specifically, in actual operation scenarios, when faced with the task of replacing the inner linings inside the first drum 8, the second drum 9, and the third drum 10, taking the first inner lining 11 as a typical example for detailed explanation, the operator first needs to press button 21. The instant button 21 is successfully pressed, the closely connected extrusion column 22, driven by the internal mechanical transmission structure, begins to move smoothly inward along a predetermined track. As the extrusion column 22 continues to move inward, the resulting thrust is transmitted to the locking pin 19, causing the locking pin 19 to retract inward until it is fully retracted into the first inner lining 11. Next, the operator places both hands in the appropriate positions on the first inner lining 11 and then slowly lifts the first inner lining 11 upward with a uniform and stable force. During this upward lifting process, the first inner lining... The locking block 16 on 11 interacts with the corresponding slot or locking structure inside the drum and gradually moves outward, thereby successfully unlocking the first inner liner 11 from the locked state with the first drum 8. After the old first inner liner 11 is successfully removed, the operator can place the pre-prepared new first inner liner 11 in the corresponding position inside the first drum 8 according to the correct direction and position, and then gradually adjust its posture and position to ensure that it is installed in place. Finally, when the machine restarts and starts to run at high speed, due to the strong centrifugal force, the locking pin 19, which was originally in a contracted state, will move outward again along the predetermined path under the traction of the centrifugal force, and return to the state of being firmly connected with the first drum 8, thereby ensuring that the newly installed first inner liner 11 can be fixed during the operation of the machine.
[0041] Working principle: In the process of using the centrifugal separation device for high-efficiency extraction of casein from yak milk, first open the lid 3 using the handle 4, then pour the yak milk into the first drum 8, then close the lid 3, start the motor 6 to drive the rotating column 5 to rotate, so that the yak milk inside the first drum 8 flows into the second drum 9 after being filtered by the first liner 11, then flows into the third drum 10 after being filtered by the second liner 12, and finally flows into the tank 1 after being filtered by the third liner 13. This completes the entire centrifugation process. When it is necessary to replace the inner linings inside the first drum 8, the second drum 9, and the third drum 10, taking the first inner lining 11 as an example, first press the button 21 to make the extrusion column 22 move inward, thereby causing the locking pin 19 to move inward and retract into the interior of the first inner lining 11. Then lift the first inner lining 11 upward, causing the locking block 16 to move outward, thereby unlocking the first inner lining 11. Then reinstall the new first inner lining 11. As the machine starts, the presence of centrifugal force causes the locking pin 19 to reconnect with the first drum 8.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
