Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to a dual-medium cooling device for centrifuge casting. Background Art

[0002] Centrifugal casting is a commonly used molding process that involves filling a mold with molten material under centrifugal force and allowing it to solidify on the inner wall of the cylinder while rotating, forming hollow castings such as tubular and cylindrical parts. This process offers advantages such as dense structure, good mechanical properties, and uniform wall thickness. During the centrifugal casting process, the high-temperature molten material remains at a high temperature after molding, requiring a cooling medium to cool it down. Failure to cool the material in a timely manner will not only affect the quality of the casting but may also shorten the service life of the mold. Natural cooling or simple air cooling methods are also used, which are slow and uneven, resulting in large residual stresses within the casting and prone to defects such as deformation and cracks. Especially when casting large, thick-walled castings, due to large differences in cooling rates, the inside and outside of the casting are cooled unevenly, resulting in significant differences in microstructure and performance, seriously affecting the service life and reliability of the casting. In addition, the cooling systems in existing technologies generally use a single cooling medium, which cannot flexibly adjust the cooling strategy according to the casting material and structural characteristics. While some improved centrifugal casting cooling technologies have emerged in recent years, such as segmented cooling and variable parameter cooling, these technologies often suffer from complex structures, low control precision, high energy consumption, and high maintenance costs. Existing technologies are particularly deficient in cooling medium recycling and heat recovery, leading to energy waste and environmental pollution. Summary of the Invention

[0018] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0021] like Figure 1 and Figure 6As shown, the embodiment of the present application proposes a dual-medium cooling device for centrifugal casting, comprising a base 1, on which a driving device 2 and an outer tank body 11 are provided, and a cover 4 is hingedly connected to the front opening of the outer tank body 11. The two ends of the outer tank body 11 are fixed to the base 1 through a cylindrical seat, and an inner tank body 16 is provided inside the outer tank body 11. The two ends of the inner tank body 16 are rotatably connected to the inside of the outer tank body 11 through a swivel, so that the molten material is evenly distributed under the action of centrifugal force to form a casting. During implementation, the driving device 2 drives the inner tank body 16 to rotate and connect to the outer tank body 11, so that the molten material is centrifugally rotated and cast in the inner tank body 16 to form a cast finished part, wherein the driving device 2 can use a variable frequency motor to achieve precise control of the rotation speed.

[0022] In addition, if Figure 6 As shown, in this embodiment, the outer wall diameter of the inner tank body 16 is smaller than the inner wall diameter of the outer tank body 11, so that a cavity 17 is formed between the outer tank body 11 and the inner tank body 16, and the spacing of the cavities 17 is 6cm-10cm. At the initial stage of pouring, high-temperature molten material is injected into the inner tank body 16. At this time, the cavity 17 serves as a passive insulation layer to keep the inner tank body 16 warm during the pouring process. After the pouring and molding stage is completed, a cooling medium is applied to the cavity 17. The cooling medium is forced to circulate in the cavity 17 and fully exchanges heat with the outer wall of the inner tank body 16 to reduce the temperature of the inner tank body 16. The cooling process does not directly contact the molded part, avoiding scouring, corrosion or contamination of the molded part surface by the cooling medium, ensuring that heat is evenly removed from all directions, avoiding defects such as internal stress, deformation or cracks caused by excessive local cooling, and ensuring the dimensional accuracy and intrinsic quality of the molded part.

[0023] In this embodiment, if Figure 1 、 Figure 5 、 Figure 6 and Figure 9 As shown, the upper housing 3 is mounted on top of the outer tank 11. A liquid supply pipe 6 is connected to the upper housing 3, which is equipped with a control valve for regulating the flow of the cooling medium. The bottom and top of the sidewall of the upper housing 3 are connected to the clamping chamber 17 via a second connecting pipe 13 and a first connecting pipe 12, respectively. An air supply pipe 7 is connected to the top of the upper housing 3, which is connected to an air injection mechanism 5. The air injection mechanism 5 is located at the front opening of the outer tank 11.

[0024] In addition, a partition 21 is laterally provided in the inner cavity of the upper box body 3, and the material of the partition 21 is a stainless steel mesh. After the water is injected into the upper box body 3 through the liquid supply pipe 6, the cooling liquid in the lower compartment 23 may splash due to turbulence or pressure fluctuations. At this time, the partition 21 blocks the water from splashing into the upper compartment 22, thereby preventing the water from splashing into the air supply pipe 7. The partition 21 divides the inner cavity of the upper box body 3 into an upper compartment 22 and a lower compartment 23. The liquid supply pipe 6 is connected to the end of the upper box body 3, passes through the partition 21 and is inserted into the lower compartment 23. Furthermore, a lower box body 10 is provided at the bottom of the outer tank body 11. The lower box body 10 is provided with an air supply mechanism and a liquid outlet pipe 20. The top and the top of the side wall of the lower box body 10 are connected to the clamping cavity 17 through the fourth connecting pipe 15 and the third connecting pipe 14 respectively.

[0025] Among them, such as Figure 10 As shown, the liquid supply pipe 6, lower compartment 23, second connecting pipe 13, clamping chamber 17, fourth connecting pipe 15, and lower housing 10 form a flow path for the liquid cooling medium. Cooling water is flushed into clamping chamber 17 via second connecting pipe 13. Under the action of gravity, the liquid flows evenly downward along the wall of inner tank 16 in clamping chamber 17, forming a liquid film wrapped around the outer wall of inner tank 16. This "liquid film" flow pattern ensures sufficient and continuous contact between the cooling liquid and the outer wall of inner tank 16, efficiently removing heat from inner tank 16 and its internal molded parts through forced convection heat transfer. Furthermore, the liquid, after heat exchange, flows through fourth connecting pipe 15 into lower housing 10 for recovery.

[0026] Further, such as Figure 11 As shown, the gas flow path is formed by the gas supply mechanism, the lower box 10, the third connecting pipe 14, the clamping cavity 17, the first connecting pipe 12, the upper compartment 22, the gas supply pipe 7, and the injection mechanism 5. The cooling gas enters the lower box 10 through the gas supply pipe 9, flows upward, and then enters the clamping cavity 17 through the third connecting pipe 14, where it comes into countercurrent contact with the downward-flowing liquid, gradually reducing the gas temperature. After becoming a gas cooling medium, it enters the injection mechanism 5 through the first connecting pipe 12, the upper compartment 22, and the gas supply pipe 7 and is directly injected into the inner tank 16, performing gas injection cooling on the cast molded parts in the inner tank 16. This gas injection cooling method has a fast cooling speed and strong penetration, directly acting on the surface of the casting, making up for the deficiency that liquid cooling cannot reach the internal area.

[0027] Furthermore, a portion of the circumferential outer wall of the inner tank body 16 located within the clamping cavity 17 is equidistantly provided with a number of fins 18. When the cooling liquid is blocked by the fins 18 as it flows downward, it will experience circumferential flow, collision, separation, and reattachment at the fins 18, effectively destroying the laminar boundary layer close to the wall, slowing down the liquid flow rate, increasing the contact time with the inner tank body 16, and forcing the low-temperature liquid in the mainstream area to mix with the heated liquid in the boundary layer, thereby improving the heat exchange effect. In addition, when the temperature of the cast molded parts in the inner tank body 16 is transferred through the inner tank body 16, the fins 18 can effectively improve the heat dissipation efficiency and enhance the contact effect with the flowing liquid, thereby further improving the heat exchange effect.

[0028] In this embodiment, if Figure 1 and Figure 5 As shown, the gas supply mechanism includes a gas generating mechanism and an aeration mechanism 19 . The gas generating mechanism is arranged on the base 1 , and the aeration mechanism 19 is arranged in the lower box 10 .

[0029] Specifically, the gas generating mechanism includes a gas compressor 8, the outlet end of which is connected to the aeration mechanism 19 via the air supply pipe 9. During operation, the gas compressor 8 operates to supply high-pressure gas through the air supply pipe 9 into the aeration mechanism 19. The aeration mechanism 19 distributes the gas uniformly in the form of small bubbles within the lower housing 10. The incoming gas exchanges heat with the hot water received by the lower housing 10 after heat exchange, thereby lowering the temperature of the water in the lower housing 10. After the water in the lower housing 10 is cooled, it is then transported to the heat exchanger. After heat exchange by the heat exchanger, it can be directly connected to the liquid supply pipe 6 for recycling. The heat exchanged gas rises within the clamping cavity 17, undergoes further heat exchange and cooling, and is then sprayed into the inner tank 16 by the jet mechanism 5 to blow air onto the molded part. The flowing gas, carrying the heat dissipated by the molded part, flows out from the open end of the outer tank 11.

[0030] In some embodiments, as Figure 7 and Figure 8 As shown, the aeration mechanism 19 includes an air chamber 191, a plurality of aeration tubes 192, and a plurality of openings 193 evenly distributed on each aeration tube 192. The air chamber 191 is fixed within the lower housing 10, and the air supply tube 9 is connected to the air chamber 191. The aeration tubes 192 are positioned above the air chamber 191. High-pressure gas generated by the gas compressor 8 is supplied to the air chamber 191 via the air supply tube 9. Pressure pulsations of the gas are effectively absorbed, creating a relatively stable pressure field within the air chamber 191. The high-pressure gas is then distributed to each aeration tube 192, fundamentally avoiding the problem of excessive aeration in certain areas and "blind aeration zones" in certain areas due to uneven air supply. The gas is then sprayed into the lower housing 10 through the aeration tubes 192, transforming into uniform bubbles that come into contact with the hot liquid recovered from the lower housing 10 for heat exchange, minimizing the temperature of the liquid.

[0031] Furthermore, each opening 193 is provided with a one-way valve 194, which allows gas to only be ejected outward, preventing liquid from entering the aeration pipe 192. Furthermore, an outlet pipe 195 is provided on the one-way valve 194, and an outlet opening 196 is circumferentially opened on the outer wall of the outlet pipe 195. A baffle 197 is fixed to the top of the outlet pipe 195, and a number of gas distribution openings 198 are opened on the baffle 197. The gas is diverted and ejected through the multiple outlet openings 196, and then floats upward to contact the gas distribution openings 198 on the baffle 197, which has a "shearing" and "collision-breaking" effect on the bubbles. When the bubbles hit the baffle, their kinetic energy is absorbed, and their size is further torn and broken, causing the bubbles to further decompose into tiny bubbles, further enhancing the contact effect between the gas and the liquid and the heat exchange effect.

[0032] like Figure 2-Figure 4 As shown, the jet mechanism 5 in this embodiment includes a fixed plate 501, a swing arm, a push rod, and an air jet hose 506. The fixed plate 501 is fixed to the top of the front opening of the outer tank body 11, the swing arm is arranged on the fixed plate 501, and the push rod is arranged between the swing arm and the fixed plate 501. One end of the air jet hose 506 is connected to the air supply pipe 7, and the other end is connected to the air jet nozzle 507. When the cover 4 is closed, the push rod drives the swing arm to rise, so that the swing arm and the air jet nozzle 507 are higher than the front opening of the outer tank body 11, which facilitates the opening and closing of the cover 4. When the cast finished parts in the inner tank body 16 need to be cooled, the push rod drives the swing arm to descend, so that the swing arm drives the air jet nozzle 507 to extend into the front opening of the outer tank body 11, so that the ejected gas acts on the inner tank body 16 to cool the cast finished parts.

[0033] Exemplarily, the swing arm includes a first arm 503 and a second arm 505, one end of the first arm 503 is hinged to the bottom of the fixed plate 501, and the other end is hinged to one end of the second arm 505; the push rod includes a first push rod 502 and a second push rod 504, the first push rod 502 is hinged to the top of the fixed plate 501, and the output end of the first push rod 502 is hinged to the middle of the first arm 503; the second push rod 504 is hinged to the bottom of the fixed plate 501, and the output end of the second push rod 504 is hinged to the middle of the second arm 505.

[0034] When the push rod drives the swing arm upward, the first push rod 502 retracts, driving the hinged end of the first arm 503 and the second arm 505 upward. Furthermore, the second push rod 504 advances, pushing the second arm 505 upward, thereby raising the air nozzle 507. Conversely, when the cast finished product in the inner tank 16 needs to be cooled, the first push rod 502 advances, while the second push rod 504 retracts, driving the first arm 503 and the second arm 505 downward, thereby causing the air nozzle 507 to flip and extend into the front opening of the outer tank 11.

[0035] Working principle: The molten material is injected into the inner tank body 16 and the cover 4 is closed; the driving device 2 drives the inner tank body 16 to rotate in the outer tank body 11, and the molten material is formed along the inner wall of the inner tank body 16 under the action of centrifugal force; at this time, the cavity 17 between the outer tank body 11 and the inner tank body 16 is temporarily used as an insulation space to ensure the stability of the molding process.

[0036] The cooling phases are as follows: Liquid cooling (overall cooling): Liquid cooling medium (such as cooling water) enters the lower compartment 23 of the upper box body 3 through the liquid supply pipe 6 (the partition net 21 prevents liquid from splashing into the upper compartment 22); the coolant flows into the clamping cavity 17 through the second connecting pipe 13 at the bottom of the upper box body 3, and under the action of the fins 18 on the outer wall of the inner tank body 16, a uniform liquid film is formed and flows downward along the wall surface, fully contacting the high-temperature inner tank body 16, and quickly removes heat through forced convection heat exchange, thereby achieving overall cooling of the casting; the hot liquid after heat exchange flows into the lower box body 10 through the fourth connecting pipe 15 at the top of the lower box body 10, completing the liquid circulation recovery.

[0037] Gas cooling (local precision cooling): The gas compressor 8 of the gas supply mechanism generates high-pressure gas, which is delivered to the aeration mechanism 19 in the lower housing 10 through the gas supply pipe 9. The aeration mechanism 19 stabilizes the air pressure through the air chamber 191, and then disperses the gas into tiny bubbles through the opening 193 of the aeration pipe 192 (with a one-way valve 194 to prevent liquid backflow). After the bubbles are ejected through the outlet opening 196 of the outlet pipe 195, they are further broken up by the baffle 197, fully exchanging heat with the hot liquid recovered in the lower housing 10, thereby reducing the gas temperature. The cooled gas enters the clamping chamber 17 through the third connecting pipe 14 on the side wall of the lower box body 10, and forms countercurrent contact with the downward-flowing liquid. After further cooling, it enters the upper compartment 22 of the upper box body 3 through the first connecting pipe 12 on the top of the side wall of the outer tank body 11; The low-temperature gas is delivered to the injection mechanism 5 through the gas supply pipe 7. The position of the air nozzle 507 is adjusted by the first arm 503, the second arm 505, the first push rod 502, and the second push rod 504 (it rises to avoid interference when the cover 4 is closed, and descends to extend into the inner tank body 16 during cooling), and the gas is precisely injected into the inner tank body 16 to perform local targeted cooling on the key parts of the casting.

[0038] Liquid cooling achieves rapid cooling of the entire casting, gas cooling makes up for insufficient local cooling, and the dual media work together to solve the unevenness problem of the traditional single cooling method; at the same time, the aeration mechanism 19 strengthens the gas-liquid heat exchange, and the fins 18 improve the liquid-solid heat exchange efficiency, realizing the recycling of the cooling medium, taking into account both high efficiency and energy saving and environmental protection.

[0039] The above describes the basic principles, main features, and advantages of the present invention. However, the above is only a specific embodiment of the present invention, and the technical features of the present invention are not limited thereto.
