Technical Field

[0001] The utility model relates to the technical field of whey protein ultrafiltration, in particular to an ultrafiltration device for whey protein. Background Art

[0002] Ultrafiltration is one of the membrane separation technologies that uses pressure as a driving force. The purpose is to separate large molecules from small molecules, and the membrane pore size is between 20-1000A°. Hollow fiber ultrafilter (membrane) has the advantages of high filling density per unit container and small footprint.

[0003] Through patent search, it is found that there is an ultrafiltration device for extracting whey protein with publication number CN217725166U. Through the structural design of the collecting barrel, the whey protein mixture can be efficiently stirred, making it more convenient for the subsequent extraction of whey protein, thereby ensuring the subsequent extraction quality. However, when the stirring is completed and the material is discharged, a part of the whey protein will adhere to the inner surface of the collecting barrel and cannot be effectively discharged, resulting in a waste of a part of the whey protein, which is relatively inconvenient to use. Therefore, we propose an ultrafiltration device for whey protein to solve or improve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5, including an ultrafiltration component 1. The structure of the ultrafiltration component 1 in this patent document is exactly the same as that of the ultrafiltration component 1, the rotating shaft 2 and the stirring plate 3 in the comparative document, and they will not be described in detail here. The rotating shaft 2 installed inside the ultrafiltration component 1 is rotated by a bearing. The part used to drive the rotating shaft 2 to rotate in this patent is the same as that in the comparative document and is not drawn in the figure, so they will not be described in detail here. The stirring plate 3 fixed to the surface of the rotating shaft 2 will drive the fixed stirring plate 3 to rotate when the rotating shaft 2 rotates. The stirring plate 3 is symmetrically fixed in several groups on the surface of the rotating shaft 2. The scraper 4 is inserted inside the stirring plate 3. When the stirring plate 3 rotates, it will drive the scraper 4 inserted inside to rotate. The linkage rod 11 is fixed to the surface of the scraper 4. The limit plate 9 is fixed to one end of the linkage rod 11. The limit plate 9 can limit the position of the linkage rod 11 to avoid The linkage rod 11 is detached from the inside of the stirring plate 3, and a spring 10 is sleeved on the surface of the linkage rod 11. One end of the spring 10 contacts the surface of the limit plate 9, and the other end contacts the inner surface of the stirring plate 3. The second push block 8 is fixed to the surface of the limit plate 9. When the second push block 8 moves, it will drive the fixed limit plate 9 to move. When the limit plate 9 moves, it will drive the fixed linkage rod 11 to move. When the linkage rod 11 moves, it will drive the fixed scraper 4 to move. When the limit plate 9 moves, it will squeeze the spring 10 to deform the spring 10 and generate elastic potential energy. When there is no external interference, the spring 10 will push the limit plate 9 to move so that the limit plate 9 drives the fixed second push block 8 and the linkage rod 11 back to the initial position. When the linkage rod 11 moves, it will drive the fixed scraper 4 to move. There are two groups of linkage rods 11, limit plates 9, second push blocks 8 and springs 10 symmetrically arranged inside a group of stirring plates 3.

[0020] The connecting rod 6 is arranged inside the rotating shaft 2, and an electric push rod 5 is fixed inside the rotating shaft 2. The connecting rod 6 is fixed to the top end of the output shaft of the electric push rod 5. The electric push rod 5 can drive the connecting rod 6 fixed on the top end of the output shaft to move. The electric push rod 5 is fixed to the top side of the rotating shaft 2. The first push block 7 is fixed to the surface of the connecting rod 6. When the connecting rod 6 moves, it will drive the fixed first push block 7 to move. Several groups of first push blocks 7 are fixed on the surface of the connecting rod 6 and the first push blocks 7 are located on the top side of the second push block 8. When the first push block 7 moves, it will contact and squeeze the surface of the second push block 8, so that the second push block 8 moves to the side close to the stirring plate 3. The interior of the rotating shaft 2 is provided with a groove for the connecting rod 6 and the first push block 7 to move.

[0021] Working principle: when the whey protein is stirred, the electric push rod 5 will push the connecting rod 6 to move, so that the connecting rod 6 drives the first push block 7 to move. When the first push block 7 moves, the surface will contact the surface of the second push block 8 and squeeze the surface of the second push block 8 to move it. When the second push block 8 moves, it will drive the limit plate 9 to move. When the limit plate 9 moves, it will drive the linkage rod 11 to move. When the linkage rod 11 moves, it will drive the scraper 4 to move to the side away from the stirring plate 3 and make one side surface of the scraper 4 fit the inner surface of the ultrafiltration component 1, so that when the stirring plate 3 rotates, the scraper 4 is driven to the inner surface of the ultrafiltration component 1. The whey protein liquid adhered to the surface is scraped off, which reduces the problem of wasting part of the whey protein due to the whey protein adhering to the inner surface of the ultrafiltration component 1. It is relatively convenient to use. After the unloading is completed, the electric push rod 5 can drive the connecting rod 6 to move in the opposite direction, so that the connecting rod 6 drives the first push block 7 to move in the opposite direction. At this time, the spring 10 will push the limit plate 9 to move, so that the limit plate 9 drives the linkage rod 11 and the scraper 4 to move, so that the scraper 4 moves to the inside of the stirring plate 3 and no longer contacts the inner surface of the ultrafiltration component 1, thereby reducing the friction force when the rotating shaft 2 rotates, making it easier to continue stirring the whey protein, and it is relatively convenient to use.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
