Description

Technical Field

[0001] This utility model relates to a heat dissipation mechanism, specifically to a water-cooled roller structure for an amorphous vacuum belt spinning machine. Background Technology

[0002] Amorphous vacuum ribbon spinning machine is used to prepare amorphous ribbons. Molten amorphous master alloy in a crucible is sprayed through a gap at the bottom of the crucible onto the surface of a water-cooled spinning roller of a rapidly rotating amorphous vacuum ribbon spinning machine. The alloy melt is rapidly cooled and spun out to form an amorphous ribbon.

[0003] Water-cooled strip spinning rollers typically have a copper surface, with circulating cooling water flowing through their interior. While copper rollers have a high thermal conductivity, allowing the heat from the molten alloy to be quickly transferred to the circulating cooling water, the commonly used cooling channels in water-cooled strip spinning rollers are straight-through slit channels. This means the cooling water enters from one end of the roller, passes through a cylindrical slit channel along the shaft, and exits from the other end. This type of roller has a large cross-sectional area, resulting in a high flow rate and low velocity of the cooling water, leading to poor cooling performance. Utility Model Content

[0004] To address at least one of the aforementioned problems, according to one aspect of the present invention, a water-cooled roller structure for an amorphous vacuum belt spinning machine is provided.

[0005] The water-cooled roller structure of the amorphous vacuum spinning machine includes an inner layer structure with a first water inlet and a first water outlet that are interconnected; and an outer layer structure with a second water outlet, which is fitted onto the inner layer structure, and the two together form a first space that connects the first water outlet and the second water outlet, with the second water outlet and the first water inlet located on the same side.

[0006] Because the amorphous vacuum spinning machine water-cooled roller structure of this application has a double-layer structure, and the first water inlet and the first water outlet are connected, and the first water outlet is connected to the second water outlet through the first space, the surface area of ​​the amorphous vacuum spinning machine water-cooled roller structure in contact with water can be increased. At the same time, the water inlet and outlet are separated by the water inlet channel between the first water inlet and the first water outlet, and the water outlet channel between the first water outlet and the second water outlet, which avoids the reverse mixing of the rotating water flow of the amorphous vacuum spinning machine water-cooled roller structure. This is particularly practical for high-speed working conditions and can improve the cooling effect.

[0007] In some embodiments, the inner layer structure includes an inner roller structure, a first outlet is disposed on the inner roller structure, and the inner roller structure has a first channel connecting the first outlet and the first inlet; at least one of the two opposite end faces of the inner roller structure is provided with at least one set of end face water grooves, and / or the outer periphery of the inner roller structure is provided with at least one set of outer periphery water grooves; the end face water grooves are configured to connect the first outlet with the outer periphery of the inner roller structure; the outer periphery water grooves are configured to connect the two opposite end faces of the inner roller structure.

[0008] Therefore, when cooling water flows out from the first outlet, it can pass through the end face water groove and / or the outer peripheral water groove under the action of centrifugal force while the water-cooled roller structure of the amorphous vacuum spinning machine rotates, and then flow out through the second outlet. Due to the setting of the end face water groove and / or the outer peripheral water groove, the cross-sectional area of ​​the unit flow channel can be reduced, and the flow rate of the cooling water can be increased. Moreover, due to the setting of the end face water groove and / or the outer peripheral water groove, the cross-sectional area of ​​the unit flow channel of the outlet channel is smaller than that of the unit flow channel of the inlet channel. Since the inlet channel carries water with a lower temperature and the outlet channel carries water with a higher temperature, the flow rate of the higher temperature water flowing through the outlet channel with a smaller unit flow channel cross-sectional area is faster. This allows the higher temperature water to flow out from the second outlet faster, while the lower temperature water flows out from the first outlet more slowly, thereby improving the cooling effect.

[0009] In some embodiments, multiple sets of end-face water tanks form a helical gear structure on the end face of the inner roller structure. This allows the rotation direction of the water-cooled roller structure of the amorphous vacuum spinning machine to be aligned with the rotation direction of the helical gears, thereby increasing the flow rate of the higher-temperature water in the end-face water tanks and improving the cooling effect.

[0010] In some embodiments, multiple sets of peripheral water tanks form a helical gear structure on the outer periphery of the inner roller structure. This allows the rotation direction of the water-cooled roller structure of the amorphous vacuum spinning machine to be aligned with the rotation direction of the helical gears, thereby increasing the flow rate of the warmer water in the peripheral water tanks and improving the cooling effect.

[0011] In some embodiments, the outer structure includes an outer roller structure having a first receiving cavity for accommodating the inner roller structure; the end face water trough, the outer roller structure, and the inner roller structure together form a first independent water channel, and / or the outer peripheral water trough, the outer roller structure, and the inner roller structure together form a second independent water channel. This ensures a stable water flow path.

[0012] In some embodiments, the sides of the end-face water tank are arranged radially along the inner roller structure. This reduces the resistance of the side of the end-face water tank to the cooling water, thereby increasing the flow rate of the warmer water in the end-face water tank and improving the cooling effect.

[0013] In some embodiments, the width of the end face water groove increases along the radial direction of the inner roller structure as the diameter of the inner roller structure increases. This increases the volume of coolant during cooling, resulting in better heat transfer.

[0014] In some embodiments, the inner layer structure further includes an inner tube, a first water inlet is disposed on the inner layer roller structure through the inner tube, the inner tube is disposed on one end of the inner layer roller structure, and the first water inlet is connected to the first water outlet through a first channel; the outer layer structure further includes an outer tube, a second water outlet is disposed on the outer tube, the outer tube is disposed on the end of the outer layer roller structure on the same side as the inner tube, and the second water outlet is connected to the first receiving cavity.

[0015] Since the first water inlet and the first water outlet are connected through the first channel, and the first water outlet is connected to the second water outlet through the first space, the surface area of ​​the water-cooled roller structure of the amorphous vacuum spinning machine in contact with water can be increased, and the water inlet and outlet channels can be separated, thereby improving the cooling effect.

[0016] In some embodiments, the outer peripheral water tank is configured to communicate with at least one set of end face water tanks. Thus, the cooling water flowing from the first outlet can sequentially flow through the end face water tank, the outer peripheral water tank, and the end face water tank, significantly increasing the heat exchange area and improving heat exchange efficiency. In particular, when multiple sets of end face water tanks form a helical gear structure on the end face of the inner roller structure, and the inner structure also includes an inner tube, and the outer structure also includes an outer tube, the helical gears, when rotating, can generate a force that pushes the coolant between the inner and outer tubes. This force can push the coolant towards the second outlet, giving the first inlet the power to flow from the first outlet to the second outlet, eliminating the need for a one-way valve for control, thereby simplifying the structure and reducing the occurrence of malfunctions.

[0017] In some implementations, at least one of the inner and outer layers is made of copper. This improves the heat exchange efficiency of both the inner and outer layers.

[0018] In some embodiments, the outer tube is provided with a sealing ring and / or a bearing. The sealing ring ensures the airtight connection between the outer tube and other structures, preventing leakage of lubricating oil and cooling water when the water-cooled roller structure of the amorphous vacuum spinning machine rotates; the bearing ensures that the outer tube can rotate smoothly at high speed relative to other components.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of this utility model.

[0036] Figures 1 to 7 The diagram schematically illustrates the structure of the water-cooled roller of the amorphous vacuum belt spinning machine according to a first embodiment of the present invention.

[0037] like Figure 3 As shown, the water-cooled roller structure of the amorphous vacuum spinning machine includes an inner layer structure 20 and an outer layer structure 30; the inner layer structure 20 includes an inner roller structure 21 and an inner tube 22; the outer layer structure 30 includes an outer roller structure 31 and an outer tube 32; one end of the inner tube 22 is integrally formed or machined with a first water inlet 221, and the other end is integrally formed, machined, or connected to one end face of the inner roller structure 21; one end of the outer tube 32 is integrally formed or machined with a second water outlet 321, and the other end is integrally formed, machined, or connected to one end face of the outer roller structure 31; the second water outlet 321 is located on the same side as the first water inlet 221. Figure 4As shown, the end face of the inner roller structure 21 without the inner tube 22 is integrally formed or machined with a first outlet 211. The inner roller structure 21 is integrally formed or machined with a first channel 212 communicating with the first outlet 211. The first channel 212 is connected to the inner tube 22, thereby realizing the connection between the first outlet 211 and the first inlet 221. Figure 3 As shown, the outer roller structure 31 is integrally formed or machined with a first receiving cavity 311 so that the outer roller structure 31 can be sleeved on the outer periphery of the inner roller structure 21, and the second water outlet 321 is connected to the first receiving cavity 311; the outer tube 32 is sleeved on the outer periphery of the inner tube 22; so that a first space 300 is formed between the outer structure 30 and the inner structure 20, which can connect the first water outlet 211 and the second water outlet 321.

[0038] Because the amorphous vacuum spinning machine water-cooled roller structure of this application has a double-layer structure, and the first water inlet 221 is connected to the first water outlet 211, and the first water outlet 211 is connected to the second water outlet 321 through the first space 300, the surface area of ​​the amorphous vacuum spinning machine water-cooled roller structure in contact with water can be increased. At the same time, the water inlet channel is formed between the first water inlet 221 and the first water outlet 211, and the water outlet channel is formed between the first water outlet 211 and the second water outlet 321, so as to realize the separation of water inlet and outlet, and avoid the reverse mixing of rotating water flow in the amorphous vacuum spinning machine water-cooled roller structure. This is particularly practical for high-speed working conditions and can improve the cooling effect. It also solves the problem that it is inconvenient to design water inlet and outlet channels when using water cooling for single-axis hubs.

[0039] In some preferred embodiments, such as Figures 3 to 5As shown, at least one of the two opposite end faces of the inner roller structure 21 is provided with at least one set of end face water grooves 213; the end face water grooves 213 are configured to connect the first water outlet 211 with the outer periphery of the inner roller structure 21. Therefore, when cooling water flows out from the first outlet 211, it can pass through the end face water groove 213 under the action of centrifugal force while the water-cooled roller structure of the amorphous vacuum spinning machine is rotating, and then flow out through the second outlet 321. Due to the setting of the end face water groove 213, the cross-sectional area of ​​the unit flow channel can be reduced, and the flow rate of the cooling water can be increased. Moreover, due to the setting of the end face water groove 213, the cross-sectional area of ​​the unit flow channel of the outlet channel is smaller than that of the unit flow channel of the inlet channel. Since the inlet channel carries water with a lower temperature and the outlet channel carries water with a higher temperature, the flow rate of the higher temperature water flowing through the outlet channel with a smaller unit flow channel cross-sectional area is faster. This allows the higher temperature water to flow out from the second outlet 321 faster, while the lower temperature water flows out from the first outlet 211 more slowly, thereby improving the cooling effect. Preferably, multiple sets of end-face water grooves 213 form a helical gear structure on the end face of the inner roller structure 21, thereby adjusting the rotation direction of the water-cooled roller structure of the amorphous vacuum spinning machine to be consistent with the rotation direction of the helical gear, thus increasing the flow rate of the higher-temperature water in the end-face water grooves 213 and improving the cooling effect; it also simplifies the water channel structure and improves the production efficiency. Preferably, the sides of the end-face water grooves 213 are arranged along the radial direction of the inner roller structure 21 to reduce the resistance of the sides of the end-face water grooves 213 to the cooling water, thereby increasing the flow rate of the higher-temperature water in the end-face water grooves 213 and improving the cooling effect. Preferably, the groove width of the end-face water grooves 213 increases along the radial direction of the inner roller structure 21 as the diameter of the inner roller structure 21 increases.

[0040] In some preferred embodiments, reference continues to be made to Figures 3 to 5As shown, at least one set of peripheral water grooves 214 are provided on the outer periphery of the inner roller structure 21; the peripheral water grooves 214 are configured to connect the two opposite end faces of the inner roller structure 21. Therefore, when cooling water flows out from the first outlet 211, it can pass through the outer peripheral water tank 214 under the action of centrifugal force while the water-cooled roller structure of the amorphous vacuum spinning machine is rotating, and then flow out through the second outlet 321. Due to the setting of the outer peripheral water tank 214, the cross-sectional area of ​​the unit flow channel can be reduced, and the flow rate of the cooling water can be increased. Moreover, due to the setting of the outer peripheral water tank 214, the cross-sectional area of ​​the unit flow channel of the outlet channel is smaller than that of the unit flow channel of the inlet channel. Since the inlet channel carries water with a lower temperature and the outlet channel carries water with a higher temperature, the flow rate of the higher temperature water flowing through the outlet channel with a smaller unit flow channel cross-sectional area is faster. This allows the higher temperature water to flow out from the second outlet 321 faster, while the lower temperature water flows out from the first outlet 211 more slowly, thereby improving the cooling effect. Preferably, multiple sets of peripheral water tanks 214 form a helical gear structure on the outer periphery of the inner roller structure 21, thereby adjusting the rotation direction of the water-cooled roller structure of the amorphous vacuum spinning machine to be consistent with the rotation direction of the helical gear, so as to increase the flow rate of the high-temperature water in the end face water tank 213, thereby improving the cooling effect; and it can also simplify the water channel structure and improve the preparation efficiency.

[0041] When both end face water trough 213 and outer peripheral water trough 214 are provided, a first independent water channel can be formed by the end face water trough 213, outer roller structure 31 and inner roller structure 21, and / or a second independent water channel can be formed by the outer peripheral water trough 214, outer roller structure 31 and inner roller structure 21, to ensure a stable water flow path. In some embodiments, the first independent water channel can be obtained in the following ways: for example, by welding the inner side of the outer roller structure 31 to the protrusion of the end face of the inner roller structure 21 to obtain the first independent water channel; or, after the outer roller structure 31 is sleeved on the outer periphery of the inner roller structure 21, the outer roller structure 31 tightly wraps around the inner roller structure 21 by means of thermal expansion and contraction (the thermal expansion coefficient of the outer roller structure 31 is much greater than that of the inner roller structure 21) to obtain the first independent water channel. In some embodiments, the second independent water channel can be obtained in the following ways: for example, by welding the inner side of the outer roller structure 31 to the protrusion on the outer periphery of the inner roller structure 21 to obtain the second independent water channel; or, after the outer roller structure 31 is fitted onto the outer periphery of the inner roller structure 21, by means of thermal expansion and contraction (the thermal expansion coefficient of the outer roller structure 31 is much greater than that of the inner roller structure 21), the outer roller structure 31 tightly wraps around the inner roller structure 21 to obtain the second independent water channel. When multiple sets of end-face water tanks 213 form a helical gear structure on the end face of the inner roller structure 21, and the inner structure 20 also includes an inner tube 22, and the outer structure 30 also includes an outer tube 32, the helical gears can generate a force that pushes the coolant between the inner tube 22 and the outer tube 32 when rotating. This force can push the coolant towards the second outlet 321, so that the first inlet 221 has the power to flow out of the first outlet 211 and towards the second outlet 321, without the need for a one-way valve for control (e.g., Figure 12 As shown, Ansys fluid simulation demonstrates the trajectory of water flowing through the water-cooled roller structure of the amorphous vacuum spinning machine of this application, proving that without a one-way valve, the coolant can flow from the first inlet 221 into the first outlet 211 and then out through the second outlet 321, thereby simplifying the structure and reducing the occurrence of failures.

[0042] In some preferred embodiments, such as Figure 3 As shown, the outer peripheral water tank 214 is configured to communicate with at least one set of end face water tanks 213, so that the cooling water flowing out of the first outlet 211 can flow through the end face water tank 213, the outer peripheral water tank 214 and the end face water tank 213 in sequence, which greatly increases the heat exchange area, improves the heat exchange efficiency and can increase the cooling rate by more than 30%.

[0043] In some preferred embodiments, at least one of the inner layer structure 20 and the outer layer structure 30 is made of copper to improve the heat exchange efficiency of the inner layer structure 20 and the outer layer structure 30.

[0044] Figures 8 to 9 The diagram schematically illustrates the water-cooled roller structure of an amorphous vacuum tape spinning machine according to a second embodiment of the present invention. The main difference between the water-cooled roller structure of the amorphous vacuum tape spinning machine in this embodiment and that in the first embodiment is that the inner layer structure 20 does not include the inner tube 22, and the first water inlet 221 is integrally formed or machined on the end face of the inner layer roller structure 21.

[0045] In some embodiments, continue to refer to Figure 8 and Figure 9 As shown, in this embodiment, the outer layer structure 30 does not include the outer tube 32, and the second outlet 321 is integrally formed or machined on the end face of the outer roller structure 31.

[0046] Figures 10 to 11 The diagram schematically illustrates the water-cooled roller structure of an amorphous vacuum tape spinning machine according to a third embodiment of the present invention. The main difference between the water-cooled roller structure of the amorphous vacuum tape spinning machine in this embodiment and that in the first embodiment is that the outer tube 32 is provided with a sealing ring 40 and / or a bearing 50. The water interface is rotatably and sealed to the outer tube 32 via the bearing 50 and the sealing ring 40, ensuring that lubricating oil or cooling water will not leak from the interface during high-speed rotation, thus guaranteeing the sealing of the connection between the outer tube 32 and other structures and preventing lubricating oil and cooling water leakage during rotation. The bearing 50 ensures that the outer tube 32 can rotate smoothly at high speed relative to other components. The sealing ring 40 is, for example, an HNBR (hydrogenated nitrile butadiene rubber) sealing ring 40 to improve its high-temperature resistance and wear resistance.

[0047] In some embodiments, continue to refer to Figure 10 and Figure 11 As shown, a gear 60 is also connected to the outer periphery of the outer tube 32. Thus, the water-cooled roller structure of the amorphous vacuum belt spinning machine can be driven to rotate at high speed by a motor that meshes with the gear 60.

[0048] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0049] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
