Description

Technical Field

[0001] This utility model relates to a multi-layer nested centrifuge separation chamber heat dissipation device, and in particular to a multi-layer nested centrifuge separation chamber heat dissipation device, belonging to the field of centrifuge heat dissipation technology. Background Technology

[0002] Multi-layer nested centrifuges, as highly efficient separation equipment, are widely used in various fields such as chemical engineering, biopharmaceuticals, food processing, and environmental protection due to their advantages of high separation efficiency and compact layout brought about by their multi-layer nested structure. They are mainly used to achieve rapid separation and purification of components of different densities in materials. During the operation of the centrifuge, the separation chamber, as the core working component, needs to complete the material separation operation at a high speed—its speed can typically reach thousands or even tens of thousands of revolutions per minute. During this process, the friction between the separation chamber and the material, the viscous shearing action inside the material, and the heat transferred by the motor operation cause the temperature inside the separation chamber to rise rapidly.

[0003] In the field of heat dissipation for the separation chamber of multi-layer nested centrifuges, traditional technical solutions include natural heat dissipation and forced air cooling. The separation chamber of multi-layer nested centrifuges can rotate at speeds of thousands to tens of thousands of revolutions per minute. The heat generated by friction and shearing far exceeds the heat dissipation capacity of natural convection, causing the temperature inside the chamber to rise continuously and become uncontrollable within the safe threshold. At the same time, the nested structure of the multi-layer chambers hinders natural air circulation, making it difficult for the heat in the inner chambers to radiate outward through the outer shell, further aggravating heat accumulation. This method is only suitable for ordinary centrifuges with low speed and low heat generation, and is completely unsuitable for the operating conditions of multi-layer nested equipment. As for forced air cooling, the compact layout of multi-layer nested centrifuges limits the air duct design, making it difficult for the airflow generated by the fan to penetrate into the narrow gaps between the multi-layer chambers. It can only act on the surface of the outer chamber, and the inner chambers fail to dissipate heat because the airflow cannot reach them, resulting in an uneven phenomenon of "cool outer layer and hot inner layer," which affects the separation accuracy.

[0004] Therefore, there is an urgent need to improve the heat dissipation device of a multi-layer nested centrifuge separation chamber to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer nested centrifuge separation chamber heat dissipation device. Through the design of the heat dissipation structure, it combines liquid cooling and air cooling, significantly improving heat dissipation efficiency compared to traditional single natural cooling or forced air cooling. It can quickly remove the large amount of heat generated by the high-speed rotation of the separation chamber, preventing the temperature from exceeding the safety threshold. The advantage of this structure is that the coolant forms a targeted circulation loop through the output pipe, the second connecting pipe, and the first connecting pipe, which can directly act on the first connecting pipe that transfers heat from the separation chamber, making heat dissipation more precise. It solves the problem of uneven heat dissipation caused by traditional forced air cooling, which is difficult to penetrate the inner layer and results in "cool outer layer and hot inner layer". The support legs provide stable support for the chiller, ensuring the stability of the heat dissipation structure during centrifuge operation and preventing displacement of heat dissipation components and heat dissipation failure due to equipment vibration, thus improving the overall reliability of the device.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include: A multi-layer nested centrifuge separation chamber heat dissipation device includes a centrifuge body and a first connecting pipe.

[0012] Preferably, the fixed frame is provided with a plurality of sliding grooves, and a sliding rod connected to the second sealing plate is movably installed inside the sliding groove.

[0013] This utility model has at least the following beneficial effects: By combining liquid cooling and air cooling in the heat dissipation structure, the heat dissipation efficiency is greatly improved compared to traditional single natural cooling or forced air cooling. It can quickly remove the large amount of heat generated by the high-speed rotation of the separation chamber, preventing the temperature from exceeding the safety threshold. The advantage of this structure is that the coolant forms a targeted circulation loop through the output pipe, the second connecting pipe and the first connecting pipe, which can directly act on the first connecting pipe that transfers heat from the separation chamber, making heat dissipation more precise. This solves the problem of uneven heat dissipation caused by traditional forced air cooling, which is difficult to penetrate the inner layer and has a "cool outer layer and hot inner layer" effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-8 As shown in the figure, this embodiment provides a multi-layer nested centrifuge separation chamber heat dissipation device embodiment.

[0018] A multi-layer nested centrifuge separation chamber heat dissipation device includes a centrifuge body 1 and a first connecting pipe 2. A heat dissipation structure 3 is provided on the first connecting pipe 2. The heat dissipation structure 3 includes a chiller 4 installed on one side of the first connecting pipe 2. Several air coolers 5 are fixedly installed on the top of the chiller 4. Several support legs 6 are fixedly installed on the bottom of the chiller 4. A coolant tank 7 is fixedly installed at one end of the support legs 6. The coolant tank 7 is connected to the chiller 4 through a delivery pipe 8. A water pump 9 connected to the coolant tank 7 is provided on the delivery pipe 8. Several output pipes 10 are fixedly installed on one side of the chiller 4. A second connecting pipe 11 connected to the first connecting pipe 2 is fixedly installed at one end of the output pipe 10. An injection pipe 12 is fixedly installed on the top of the coolant tank 7. By combining liquid cooling and air cooling through the heat dissipation structure 3, the heat dissipation efficiency is greatly improved compared to traditional single natural cooling or forced air cooling. It can quickly remove the large amount of heat generated by the high-speed rotation of the separation chamber, preventing the temperature from exceeding the safety threshold. Before the device is started, sufficient coolant is injected into the coolant tank 7 through the injection pipe 12 to prepare the heat dissipation medium. When the centrifuge body 1 is running, its separation chamber generates heat due to high-speed rotation. The heat is transferred to the heat dissipation structure 3 through the first connecting pipe 2, and the chiller 4 and water pump 9 are started. After the water pump 9 starts, the coolant in the coolant tank 7 is transported to the chiller 4 through the delivery pipe 8. At the same time, the air cooler 5 on the top of the chiller 4 is started to quickly cool the coolant entering the chiller 4. The cooled coolant is transported to the second connecting pipe 11 through the output pipe 10 on one side of the chiller 4. The second connecting pipe 11 is connected to the first connecting pipe 2. The coolant flows in the loop formed by the second connecting pipe 11 and the first connecting pipe 2, absorbing the heat from the separation chamber transferred by the first connecting pipe 2. After absorbing the heat, the coolant flows back to the coolant tank 7, completing one heat dissipation cycle and continuously cooling the separation chamber. The support legs 6 at the bottom of the chiller 4 provide stable support for the chiller 4 throughout the process, ensuring the stable operation of the heat dissipation structure 3. The advantage of this structure is that the coolant forms a targeted circulation loop through the output pipe 10, the second connecting pipe 11, and the first connecting pipe 2, which can directly act on the first connecting pipe 2 that transfers heat from the separation chamber, resulting in more precise heat dissipation. This solves the problem of uneven cooling, where the traditional forced air cooling cannot penetrate deep into the inner layer and the outer layer is cool while the inner layer is hot. The stable support of the support legs 6 for the chiller 4 ensures the stability of the heat dissipation structure 3 during the operation of the centrifuge, preventing the heat dissipation components from shifting or failing due to equipment vibration, and improving the overall reliability of the device.

[0019] like Figures 1-8 As shown, a first connecting plate 13 is fixedly installed at one end of the first connecting pipe 2, and a second connecting plate 14 connected to the first connecting plate 13 is fixedly installed at one end of the second connecting pipe 11. An embedding groove 15 adapted to the first connecting plate 13 is opened on the second connecting plate 14. A plurality of mounting grooves 16 are opened on the first connecting plate 13. A first spring 17 is fixedly installed inside the mounting groove 16. A locking block 18 is fixedly installed at one end of the first spring 17. A plurality of locking holes 19 that cooperate with the locking block 18 are opened on the second connecting plate 14. With the arrangement of the first connecting plate 13, the second connecting plate 14, the embedding groove 15, the mounting groove 16, the first spring 17, the locking block 18, and the locking hole 19, during the device assembly stage, when it is necessary to connect the second connecting pipe 11 to the first connecting pipe 2, the second connecting plate 14 at one end of the second connecting pipe 11 is aligned with the first connecting plate 13 at one end of the first connecting pipe 2, and the second connecting plate 14 is pushed so that the first connecting plate 13 is embedded in the embedding groove 15 opened on the second connecting plate 14. During the embedding process, the locking block 18 in the mounting groove 16 on the first connecting plate 13 is squeezed by the inner wall of the second connecting plate 14, compressing the first spring 17 and retracting it into the mounting groove 16. When the second connecting plate 14 and the first connecting plate 13 are completely fitted together... The locking block 18 pops out under the elastic reset action of the first spring 17 and locks into the corresponding locking hole 19 on the second connecting plate 14, completing the quick engagement of the first connecting plate 13 and the second connecting plate 14, thereby achieving a stable connection between the second connecting pipe 11 and the first connecting pipe 2. When disassembly and maintenance are required, pressing the locking block 18 compresses the first spring 17 and disengages it from the locking hole 19, which separates the second connecting plate 14 from the first connecting plate 13, achieving quick disassembly of the second connecting pipe 11 and the first connecting pipe 2. This enables quick assembly and disassembly of the second connecting pipe 11 and the first connecting pipe 2. Compared with traditional bolt connections, no additional tools are needed, saving installation and maintenance time and improving ease of operation.

[0020] like Figures 1-8 As shown, several limiting plates 20 are fixedly installed at both ends of the second connecting plate 14. A push block 21 is provided between the limiting plates 20. A limiting rod 22 is fixedly installed at one end of the push block 21. A limiting hole 23 adapted to the limiting rod 22 is opened on the locking block 18. An insertion hole 24 is opened on both the limiting plate 20 and the push block 21. An insertion rod 25 connected to the push block 21 is installed on the limiting plate 20. With the setting of limiting plate 20, push block 21, limiting rod 22 and limiting hole 23, after the first connecting plate 13 and the second connecting plate 14 are initially engaged by the locking block 18 and locking hole 19, in order to prevent the locking block 18 from accidentally disengaging from the locking hole 19 during equipment vibration, the push block 21 between the limiting plates 20 at both ends of the second connecting plate 14 is pushed. When the push block 21 moves, it drives the limiting rod 22 at one end to move synchronously, so that the limiting rod 22 is inserted into the limiting hole 23 opened on the locking block 18. After the limiting rod 22 is inserted into the limiting hole 23, it forms a limiting constraint on the locking block 18, preventing the locking block 18 from popping out under the action of the first spring 17 or shifting due to vibration, and further locking it. When the connection between the first connecting plate 13 and the second connecting plate 14 needs to be disassembled, the push block 21 is pushed in the opposite direction, causing the limiting rod 22 to disengage from the limiting hole 23, thus releasing the limiting of the locking block 18. This allows for the disassembly of the first connecting plate 13 and the second connecting plate 14, and the limiting engagement between the limiting rod 22 and the limiting hole 23. Based on the initial engagement of the locking block 18 and the locking hole 19, a double locking mechanism is added, further improving the stability of the connection between the first connecting plate 13 and the second connecting plate 14. This completely avoids the problem of the locking block 18 disengaging from the locking hole 19 and the connection between the second connecting pipe 11 and the first connecting pipe 2 becoming loose due to the high-frequency vibration of the centrifuge, ensuring the continuous sealing of the heat dissipation circuit.

[0021] With the insertion hole 24 and the insertion rod 25, after the push block 21 is pushed to insert the limiting rod 22 into the limiting hole 23, in order to fix the position of the push block 21 and prevent it from shifting during equipment operation and causing the limiting rod 22 to disengage from the limiting hole 23, the insertion rod 25 is aligned with the insertion hole 24 on the limiting plate 20 and the push block 21, and inserted so that the insertion rod 25 passes through the insertion hole 24 of the limiting plate 20 and the push block 21, thus fixing the push block 21 and the limiting plate 20, thereby fixing the position of the limiting rod 22 and ensuring that the limiting rod 22 is always within the limiting hole 23. During disassembly, first pull out the insertion rod 25. The rod 25 releases the fixing of the push block 21 and the limiting plate 20. Then, the push block 21 is pushed in the opposite direction to make the limiting rod 22 disengage from the limiting hole 23. The disassembly is then completed according to the normal procedure. The cooperation between the insertion rod 25 and the insertion hole 24 achieves rigid fixing of the push block 21. Compared with simply relying on the friction force of the push block 21 itself for positioning, the fixing effect is more reliable and can completely resist the vibration during the operation of the centrifuge, preventing the push block 21 from shifting and the limiting rod 22 from disengaging from the limiting hole 23. This further strengthens the locking effect of the connection between the first connecting plate 13 and the second connecting plate 14, ensuring the long-term stability of the heat dissipation circuit.

[0022] like Figures 1-8 As shown, one end of the card block 18 is set as a rounded corner, and the other end of the card block 18 is set as a right angle; With one end of the locking block 18 set to a right angle and the other end of the locking block 18 set to a rounded corner, when the first connecting plate 13 and the second connecting plate 14 are assembled, the rounded corner end of the locking block 18 first contacts the inner wall of the second connecting plate 14. The rounded corner structure reduces the frictional resistance between the locking block 18 and the inner wall of the second connecting plate 14, allowing the locking block 18 to be pressed more smoothly into the mounting groove 16, reducing the feeling of jamming during assembly. When the locking block 18 is inserted into the locking hole 19, the right angle end of the locking block 18 fits against the inner wall of the locking hole 19. The right angle structure increases the contact area between the locking block 18 and the locking hole 19, and the limiting effect of the right angle can prevent the locking block 18 from shifting along the direction perpendicular to the locking direction during equipment vibration, ensuring the locking stability. When disassembling, press the right angle end of the locking block 18. The right angle structure facilitates the application of force and can stably transmit the pressing force, allowing the locking block 18 to smoothly compress the first spring 17 and disengage from the locking hole 19.

[0023] like Figures 1-8 As shown, a fixed frame 26 is fixedly installed on the top of the injection tube 12. A first sealing plate 27 is fixedly installed inside the fixed frame 26. A second sealing plate 28 connected to the fixed frame 26 is installed at one end of the first sealing plate 27. A handle 29 is fixedly installed at one end of the second sealing plate 28. Several mounting holes 30 are opened on one side of the first sealing plate 27. A second spring 31 connected to the second sealing plate 28 is fixedly installed inside the mounting holes 30. Several sliding grooves 32 are opened on the fixed frame 26. A sliding rod 33 connected to the second sealing plate 28 is movably installed inside the sliding grooves 32. With the arrangement of the fixed frame 26, the first sealing plate 27, the second sealing plate 28, the handle 29, the mounting hole 30, and the second spring 31, when injecting coolant into the coolant tank 7 or performing internal maintenance, pulling the handle 29 moves the second sealing plate 28 along the fixed frame 26. During the movement of the second sealing plate 28, the second spring 31 is compressed, causing the second sealing plate 28 to separate from the first sealing plate 27, opening the top opening of the coolant tank 7 for easy injection or maintenance. After the operation is completed, releasing the handle 29 allows the second spring 31 to push the second sealing plate 28 back to its original position under elastic reset, ensuring that the second sealing plate 28 fits tightly against the first sealing plate 27 and seals the top opening of the coolant tank 7. The mounting hole 30 on one side of the first sealing plate 27 is used to fix the second spring 31, ensuring that the second spring 31 remains stable during the movement of the second sealing plate 28 and preventing seal failure due to displacement of the second spring 31. The fixed frame 26 provides fixed support for the first sealing plate 27 and the second sealing plate 28, ensuring the overall stability of the sealing structure.

[0024] With the sliding groove 32 and sliding rod 33 in place, as the second sealing plate 28 moves along the fixed frame 26, the sliding rod 33 connected to both sides of the second sealing plate 28 slides synchronously within the sliding groove 32 opened on the fixed frame 26. The sliding cooperation between the sliding rod 33 and the sliding groove 32 guides the movement direction of the second sealing plate 28, preventing the second sealing plate 28 from shifting or getting stuck during movement, ensuring that the second sealing plate 28 can accurately fit or separate from the first sealing plate 27. At the same time, the sliding of the sliding rod 33 within the sliding groove 32 also limits the movement range of the second sealing plate 28, preventing the second sealing plate 28 from being damaged by excessive pulling, or from affecting the sealing effect due to excessive reset.

[0025] In this embodiment, as Figures 1-8 As shown in the figure, the working process of the multi-layer nested centrifuge separation chamber heat dissipation device provided in this embodiment is as follows: Before the device is started, sufficient coolant is injected into the coolant tank 7 through the injection pipe 12 to prepare the heat dissipation medium. When the centrifuge body 1 is running, its separation chamber generates heat due to high-speed rotation. The heat is transferred to the heat dissipation structure 3 through the first connecting pipe 2. The chiller 4 and water pump 9 are started. After the water pump 9 starts, the coolant in the coolant tank 7 is transported to the chiller 4 through the delivery pipe 8. At the same time, the air cooler 5 on the top of the chiller 4 is started to quickly cool the coolant entering the chiller 4. The cooled coolant is transported to the second connecting pipe 11 through the output pipe 10 on one side of the chiller 4. The second connecting pipe 11 is connected to the first connecting pipe 2. The coolant flows in the loop formed by the second connecting pipe 11 and the first connecting pipe 2, absorbing the heat from the separation chamber transferred by the first connecting pipe 2. The cooled coolant after absorbing the heat flows back to the coolant tank 7, completing one heat dissipation cycle and continuously cooling the separation chamber. The support legs 6 at the bottom of the chiller 4 provide stable support for the chiller 4 throughout the process, ensuring the stable operation of the heat dissipation structure 3.
