Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry blood utilization, and in particular to a low-temperature hemoglobin extraction device. Background Technology

[0002] Animal blood is one of the main byproducts produced during the slaughtering and processing of livestock and poultry. Rich in various nutrients and bioactive components, it possesses high nutritional and functional value. Plasma proteins are the most abundant solid components of plasma, rich in amino acids and possessing high nutritional value; they can be used as protein supplements, binders, etc. Hemoglobin is rich in porphyrin iron, a natural red pigment and iron source, and can be added to various beverages as a nutritional supplement for infants, young children, the elderly, and patients in recovery. It can also be refined into infusion drugs and chemical reagents.

[0003] Chinese utility model patent CN220812261U discloses a device for the co-production of plasma proteins and hemoglobin. This device includes a storage and filtration mechanism, a centrifuge mechanism on one side of which is located. Plasma protein preparation and hemoglobin preparation mechanisms are respectively located on the front and rear sides of the centrifuge mechanism. The plasma protein preparation mechanism includes a plasma protein desalting and concentration component, a plasma protein spray drying component, and a plasma protein preparation storage component. The hemoglobin preparation mechanism includes a hemoglobin extraction and concentration component, a hemoglobin spray drying component, and a hemoglobin preparation storage component. By incorporating the plasma protein preparation and hemoglobin preparation mechanisms, co-production and standardized processing of plasma proteins and hemoglobin can be achieved. The use of ultrafiltration and nanofiltration boxes removes solid impurities from the raw materials, improving product purity and enhancing the quality of both plasma proteins and hemoglobin.

[0004] The aforementioned co-production device is composed of multiple different functional units, which have low integration, are relatively dispersed, and occupy a large area. It is suitable for large-scale hemoglobin extraction but not for small-scale hemoglobin extraction. Therefore, proposing a small-scale extraction device with higher integration would be practical. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a low-temperature hemoglobin extraction device with a two-stage separation and integrated design, high integration, suitable for small-scale hemoglobin extraction, and good practicality.

[0006] This utility model discloses a low-temperature hemoglobin extraction device, comprising a tank body; it also includes a storage and crushing tank, an inlet pipe, a first centrifugal separator, a slag discharge pipe, a conveying pipe, a second centrifugal separator, a first drain pipe, and a second drain pipe. The tank body has an internal chamber 1. The storage and crushing tank is installed at the upper part of chamber 1 of the tank body. The storage and crushing tank has an internal chamber 2. An inlet pipe is installed at the top of the storage and crushing tank, communicating with chamber 2 of the storage and crushing tank. The upper end of the inlet pipe extends above the tank body. The first centrifugal separator is installed in the middle of chamber 1 of the tank body. The first centrifugal separator has an internal separation chamber 1. Chamber 2 of the storage and crushing tank is connected to the storage and crushing tank via a pipe... A conveying pipe is connected to the first separation chamber of centrifugal separator one. Centrifugal component one is installed inside the first separation chamber. A slag discharge pipe is installed on the side wall of centrifugal separator one, with its inner end connected to the edge of the first separation chamber. The upper end of the conveying pipe is connected to the bottom of the first separation chamber. Centrifugal separator two is installed in the lower part of the first chamber of the separator. A second separation chamber is located inside the second centrifugal separator, with centrifugal component two installed inside. A drain pipe one is installed on the side wall of the second centrifugal separator, with its inner end connected to the edge of the second separation chamber. The upper end of the drain pipe one is connected to the bottom of the second separation chamber. The bottom of chamber two is connected, and the upper end of drain pipe two is located inside the inner end of drain pipe one. During operation, livestock and poultry blood is added to chamber two of the storage and crushing tank through the inlet pipe to store the blood and break down the cells. After being fully broken down, the cells in the blood are fed into the separation chamber one of centrifugal separator one through a pipeline. Centrifugal component one drives the broken-down blood to rotate at high speed, causing the blood to begin to separate under centrifugal force. This causes the densest impurities to approach the edge of the separation chamber one of centrifugal separator one. The slag discharge pipe opens to discharge the impurities, and the conveying pipe opens to remove the remaining blood. Animal blood is fed into the second separation chamber of centrifuge tank two. Centrifuge component two drives the animal blood, after impurities have been removed, to rotate at high speed, causing the remaining animal blood to separate into layers again. This causes the heavy phase hemoglobin solution to accumulate at the edge of the second separation chamber of centrifuge tank two, while the light phase plasma protein solution is located in the inner layer of the heavy phase hemoglobin solution. Drain pipe two is opened to discharge and collect the light phase plasma protein solution containing cell membranes, and drain pipe one is opened to discharge the heavy phase hemoglobin solution. This achieves efficient extraction of hemoglobin from animal blood. Compared with existing technologies, this integrated design has a high degree of integration and is suitable for small-scale hemoglobin extraction, making it highly practical.

[0007] Preferably, it also includes a push cylinder and a second inlet pipe. The fixed end of the push cylinder is mounted on the tank body via a bracket. The piston rod of the push cylinder is connected to the storage and crushing tank. The lower end of the second inlet pipe is connected to the first separation chamber of the centrifugal separator. The upper end of the second inlet pipe extends into the second chamber from the bottom wall of the storage and crushing tank. The extension and retraction of the piston rod of the push cylinder causes the storage and crushing tank to rise and fall within the first chamber of the tank body. When the storage and crushing tank descends, the upper end of the second inlet pipe rises to the top of the second chamber of the storage and crushing tank. At this time, the chamber of the storage and crushing tank... The poultry and livestock blood in the second chamber is not input into the separation chamber of the centrifugal separator first through the second inlet pipe. The poultry and livestock blood in the second chamber of the storage and crushing tank is stored and crushed. After the cells in the poultry and livestock blood are fully crushed, the push cylinder drives the storage and crushing tank to rise, so that the upper end of the second inlet pipe descends to the bottom of the second chamber of the storage and crushing tank. At this time, the poultry and livestock blood in the second chamber of the storage and crushing tank is input into the separation chamber of the centrifugal separator first through the second inlet pipe, realizing the efficient transportation and transfer of poultry and livestock blood, which is practical.

[0008] Preferably, it also includes a stopper plate, which is installed on top of the second chamber of the storage crushing tank via a bracket. The stopper plate is located above the upper port of the second inlet pipe. When the push cylinder drives the storage crushing tank to descend, causing the upper port of the second inlet pipe to rise, the stopper plate closes the upper port of the second inlet pipe, preventing insufficiently crushed poultry and livestock blood in the second chamber of the storage crushing tank from being input into the first separation chamber of the centrifugal separator through the second inlet pipe, thereby improving practicality.

[0009] Preferably, it also includes an inlet pipe and an outlet pipe, which are installed on the outer wall of the tank and are connected to the first chamber of the tank. Cooling water is introduced into the first chamber of the tank through the inlet pipe. The cooling water cools the storage crushing tank, the first centrifugal separation tank, and the second centrifugal separation tank. Then the cooling water is discharged through the outlet pipe, thereby realizing the low-temperature extraction of hemoglobin and reducing the deterioration of hemoglobin.

[0010] Preferably, it also includes an ultrasonic crushing component, which is installed in the second chamber of the storage crushing tank; the ultrasonic crushing component vibrates the poultry and livestock blood in the second chamber of the storage crushing tank at high frequency, so that the poultry and livestock blood cells are fully crushed, and hemoglobin is released, thereby improving the extraction efficiency.

[0011] Preferably, it also includes a motor, a vertical shaft, a second centrifugal impeller, and a first centrifugal impeller. The motor is installed at the bottom of the tank, and the output shaft of the motor is connected to the lower end of the vertical shaft. The vertical shaft is rotatably installed in the second separation chamber of the second centrifugal separator. The second centrifugal impeller is installed at the lower part of the vertical shaft and is located in the second separation chamber of the second centrifugal separator. The first centrifugal impeller is rotatably installed in the first separation chamber of the first centrifugal separator, and the central shaft of the first centrifugal impeller is connected to the upper end of the vertical shaft. The second centrifugal impeller is the second centrifugal component in the second separation chamber of the second centrifugal separator, and the first centrifugal impeller is the first centrifugal component in the first separation chamber of the first centrifugal separator. The motor drives the vertical shaft to rotate, and the vertical shaft drives the second centrifugal impeller and the first centrifugal impeller to rotate, thereby causing the second centrifugal impeller and the first centrifugal impeller to rotate at high speed, thereby driving the poultry and livestock blood to rotate in the first separation chamber of the first centrifugal separator and the second separation chamber of the second centrifugal separator for centrifugal separation.

[0012] Preferably, it also includes a gearbox, which is installed between centrifugal separation tank one and centrifugal separation tank two. The upper end of the vertical shaft is driven to the input shaft of the gearbox, and the output shaft of the gearbox is driven to the central shaft of centrifugal impeller one. By setting the gearbox, the centrifugal impeller one and centrifugal impeller two rotate at different speeds, so as to achieve centrifugal separation of poultry and livestock blood in centrifugal separation tank one and centrifugal separation tank two at different speeds. This is suitable for different blood components and has good practicality.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, livestock and poultry blood is added to the second chamber of the storage and crushing tank through the inlet pipe, where the blood is stored and the cells are crushed. After being fully crushed, the cells in the blood are fed into the first separation chamber of the centrifugal separator through a pipeline. The centrifugal component drives the crushed blood to rotate at high speed, causing it to stratify under centrifugal force. This causes the densest impurities to approach the edge of the first separation chamber. The slag discharge pipe is opened to discharge the impurities, and the conveying pipe is opened to feed the remaining blood into the centrifugal separator. In the second separation chamber of the centrifuge tank, the centrifuge component drives the impurity-removed poultry and livestock blood to rotate at high speed, thereby causing the remaining poultry and livestock blood to separate into layers again. This causes the heavy phase hemoglobin liquid to accumulate at the edge of the second separation chamber of the centrifuge tank, while the light phase plasma protein liquid is located in the inner layer of the heavy phase hemoglobin liquid. The light phase plasma protein liquid containing cell membranes is discharged and collected by opening the drain pipe 2, and the heavy phase hemoglobin liquid is discharged by opening the drain pipe 1. This achieves efficient extraction of hemoglobin from poultry and livestock blood. Compared with the existing technology, this integrated design has a high degree of integration and is suitable for small-scale hemoglobin extraction work, making it highly practical.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 3As shown, a low-temperature hemoglobin extraction device includes a tank body 1; it also includes a storage and crushing tank 2, an inlet pipe 3, a first centrifugal separator 4, a slag discharge pipe 5, a conveying pipe 6, a second centrifugal separator 7, a first drain pipe 8, and a second drain pipe 9. The tank body 1 has an internal chamber 1. The storage and crushing tank 2 is installed in the upper part of the first chamber of the tank body 1. The storage and crushing tank 2 has an internal chamber 2. The inlet pipe 3 is installed on the top of the storage and crushing tank 2, and it communicates with the second chamber of the storage and crushing tank 2. The upper end of the inlet pipe 3 extends out of the tank body 1. Above, centrifugal separator 4 is installed in the middle of chamber 1 of tank body 1. Centrifugal separator 4 has a separation chamber 1 inside. Chamber 2 of storage and crushing tank 2 is connected to separation chamber 1 of centrifugal separator 4 via a pipeline. Centrifugal component 1 is installed inside separation chamber 1. A slag discharge pipe 5 is installed on the side wall of centrifugal separator 4, with its inner end connected to the edge of separation chamber 1. The upper end of conveying pipe 6 is connected to the bottom of separation chamber 1 of centrifugal separator 4. Centrifugal separator 2 7 is installed... In the lower part of the first chamber of the tank body 1, a second separation chamber is set inside the second centrifugal separator 7. A second centrifugal component is installed inside the second separation chamber. A first drain pipe 8 is installed on the side wall of the second centrifugal separator 7. The inner end of the first drain pipe 8 communicates with the edge of the second separation chamber of the second centrifugal separator 7. The upper end of the second drain pipe 9 communicates with the bottom of the second separation chamber of the second centrifugal separator 7. The upper end of the second drain pipe 9 is located inside the inner end of the first drain pipe 8. It also includes a push cylinder 10 and an inlet pipe 11. The fixed end of the push cylinder 10 is mounted via a bracket. Mounted on tank body 1, the piston rod of push cylinder 10 is connected to storage crushing tank 2, the lower end of inlet pipe 2 11 is connected to separation chamber 1 of centrifugal separator 4, and the upper end of inlet pipe 2 11 extends into chamber 2 through the bottom wall of storage crushing tank 2; it also includes a stopper plate 12, which is mounted on the top of chamber 2 of storage crushing tank 2 by a bracket, and the stopper plate 12 is located above the upper port of inlet pipe 2 11; it also includes an ultrasonic crushing assembly 15, which is installed in chamber 2 of storage crushing tank 2.

[0022] During operation, livestock and poultry blood is added to chamber two of storage and crushing tank 2 through inlet pipe 3. Ultrasonic crushing component 15 vibrates the livestock and poultry blood in chamber two of storage and crushing tank 2 at high frequency, causing the blood cells to be fully broken down and releasing hemoglobin. After being fully broken down, the cells in the livestock and poultry blood are fed into separation chamber one of centrifugal separator 4 through pipeline. Centrifugal component one drives the broken livestock and poultry blood to rotate at high speed, causing the blood to begin to separate under centrifugal force. This causes the densest impurities to approach the edge of the separation chamber of centrifugal separator 4. The slag discharge pipe 5 is then opened to release the impurities. The impurities are discharged, and the delivery pipe 6 is opened to input the remaining poultry and livestock blood into the separation chamber 2 of the centrifuge tank 2 7. The centrifuge component 2 drives the impurity-removed poultry and livestock blood to rotate at high speed, thereby causing the remaining poultry and livestock blood to separate into layers again. The heavy phase hemoglobin liquid accumulates at the edge of the separation chamber 2 of the centrifuge tank 2 7, while the light phase plasma protein liquid is located in the inner layer of the heavy phase hemoglobin liquid. The drain pipe 2 9 is opened to discharge and collect the light phase plasma protein liquid containing cell membranes, and the drain pipe 1 8 is opened to discharge the heavy phase hemoglobin liquid. This achieves efficient extraction of hemoglobin from poultry and livestock blood, compared with the existing technology which uses an integrated... With its sophisticated design and high integration, this system is suitable for small-scale hemoglobin extraction and offers excellent practicality. The piston rod of the push cylinder 10 extends and retracts, causing the storage and crushing tank 2 to rise and fall within chamber one of the tank body 1. When the storage and crushing tank 2 descends, the upper end of the inlet pipe 11 rises to the top of chamber two of the storage and crushing tank 2. At this time, the poultry and livestock blood in chamber two of the storage and crushing tank 2 will not be input into the separation chamber one of the centrifugal separator 4 through inlet pipe 11. The poultry and livestock blood in chamber two of the storage and crushing tank 2 is stored and crushed. After the cells in the poultry and livestock blood are fully crushed, the push cylinder 10 drives the storage and crushing tank 2 to rise. The height of the inlet pipe 11 causes the upper end of the inlet pipe 2 to descend to the bottom of the second chamber of the storage and crushing tank 2. At this time, the poultry and livestock blood in the second chamber of the storage and crushing tank 2 is input into the first separation chamber of the centrifugal separator 4 through the inlet pipe 11, realizing efficient transportation and transfer of poultry and livestock blood, which is practical. When the push cylinder 10 drives the storage and crushing tank 2 to descend, causing the upper end of the inlet pipe 11 to rise, the stopper plate 12 closes the upper end of the inlet pipe 11, preventing insufficiently crushed poultry and livestock blood in the second chamber of the storage and crushing tank 2 from being input into the first separation chamber of the centrifugal separator 4 through the inlet pipe 11, thus improving practicality.

[0023] It also includes an inlet pipe 13 and an outlet pipe 14, which are installed on the outer wall of the tank body 1 and are connected to the first chamber of the tank body 1. Cooling water is introduced into the first chamber of the tank body 1 through the inlet pipe 13. The cooling water cools the storage crushing tank 2, the centrifugal separation tank 1 4 and the centrifugal separation tank 2 7. Then the cooling water is discharged through the outlet pipe 14, realizing the low-temperature extraction of hemoglobin and reducing the deterioration of hemoglobin. Example 2

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, based on Embodiment 1, it further includes a motor 16, a vertical shaft 17, a second centrifugal impeller 18, and a first centrifugal impeller 19. The motor 16 is installed at the bottom of the tank 1, and the output shaft of the motor 16 is drivenly connected to the lower end of the vertical shaft 17. The vertical shaft 17 is rotatably installed in the second separation chamber of the second centrifugal separator 7. The second centrifugal impeller 18 is installed at the lower part of the vertical shaft 17 and is located in the second separation chamber of the second centrifugal separator 7. The first centrifugal impeller 19 is rotatably installed in the first separation chamber of the first centrifugal separator 4, and the central shaft of the first centrifugal impeller 19 is drivenly connected to the upper end of the vertical shaft 17. It also includes a gearbox 20, which is installed between the first centrifugal separator 4 and the second centrifugal separator 7. The upper end of the vertical shaft 17 is drivenly connected to the input shaft of the gearbox 20, and the output shaft of the gearbox 20 is drivenly connected to the central shaft of the first centrifugal impeller 19.

[0025] Centrifugal impeller 18 is the second centrifugal component in the second separation chamber of centrifugal separator 7, and centrifugal impeller 19 is the first centrifugal component in the first separation chamber of centrifugal separator 4. Motor 16 drives vertical shaft 17 to rotate, and vertical shaft 17 drives centrifugal impeller 18 and centrifugal impeller 19 to rotate, thereby causing centrifugal impeller 18 and centrifugal impeller 19 to rotate at high speed, thereby driving poultry and livestock blood to rotate in the first separation chamber of centrifugal separator 4 and the second separation chamber of centrifugal separator 7 for centrifugal separation. By setting gearbox 20, the speed of centrifugal impeller 19 and centrifugal impeller 18 are different, realizing the centrifugal separation of poultry and livestock blood in centrifugal separator 4 and centrifugal separator 7 at different speeds, which is suitable for different blood components.

[0026] like Figures 1 to 5As shown, this utility model discloses a low-temperature hemoglobin extraction device. During operation, cooling water is first introduced into chamber one of tank 1 through inlet pipe 13. The cooling water cools the storage and crushing tank 2, centrifugal separation tank one 4, and centrifugal separation tank two 7. The cooling water is then discharged through outlet pipe 14. Next, livestock blood is added to chamber two of storage and crushing tank 2 through inlet pipe 3. Ultrasonic crushing component 15 stores the livestock blood and crushes its cells. After the cells in the livestock blood are fully crushed, push cylinder 10 drives storage and crushing tank 2 to rise, and the blood is introduced into separation chamber one of centrifugal separation tank one 4 through inlet pipe two 11. Then, centrifugal impeller one 19 drives the crushed livestock blood to rotate at high speed, thereby purifying the blood. Under the action of centrifugal force, the blood begins to separate, causing the densest impurities to approach the edge of the separation chamber of centrifugal separator 4. The slag discharge pipe 5 is opened to discharge the impurities, and the conveying pipe 6 is opened to input the remaining poultry and livestock blood into the second separation chamber of centrifugal separator 7. The centrifugal impeller 18 drives the poultry and livestock blood, after removing impurities, to rotate at high speed, thereby causing the remaining poultry and livestock blood to separate again. The heavy phase hemoglobin liquid gathers at the edge of the second separation chamber of centrifugal separator 7, while the light phase plasma protein liquid is located in the inner layer of the heavy phase hemoglobin liquid. Finally, the drain pipe 9 is opened to discharge and collect the light phase plasma protein liquid containing cell membranes, and the drain pipe 8 is opened to discharge the heavy phase hemoglobin liquid, thus achieving efficient extraction of hemoglobin from poultry and livestock blood.
