DETAILED DESCRIPTION

[0031] In order to better explain the present invention, in order to understand, the following will be combined with the drawings, through specific embodiments, the present invention is described in detail.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely in combination with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all. As long as the effect of the present invention can be played, various changes can be made to the implementation scheme.

[0033] By the personnel in the art, the parts in the case are connected in turn, the specific connection and operation sequence should be referred to the following working principle, its detailed connection means, for the art known technology, the following mainly introduces the working principle and process.

[0034] As Figure 1 and Figure 6 shown, the embodiment of the application proposes a centrifuge casting double medium cooling device, comprising a base 1, the base 1 is provided with a driving device 2 and an outer tank body 11, the front end opening of the outer tank body 11 is hinged with a cover 4. The two ends of the outer tank body 11 are fixed on the base 1 through the cylindrical seat, and the inner tank body 16 is arranged in the outer tank body 11, and the two ends of the inner tank body 16 are rotatably connected in the outer tank body 11 through the rotating ring, so that the molten material is uniformly distributed to form a casting under the action of centrifugal force. When implementing, the driving device 2 drives the inner tank body 16 to rotate and connect in the outer tank body 11, so that the molten material is centrifugally poured in the inner tank body 16 to form a pouring finished product, wherein the driving device 2 can be selected as a variable frequency motor to realize accurate control of the rotating speed.

[0035] In addition, as Figure 6 shown, the outer wall diameter of the inner tank body 16 in the embodiment is smaller than the inner wall diameter of the outer tank body 11, so that a clamping cavity 17 is formed between the outer tank body 11 and the inner tank body 16, and the spacing of the clamping cavity 17 is 6cm-10cm. In the initial pouring stage, the high-temperature molten material is injected into the inner tank body 16, at this time, the clamping cavity 17 acts as a passive heat preservation layer for heat preservation of the inner tank body 16 during pouring. When the pouring forming stage is completed, cooling medium is applied to the clamping cavity 17, and the cooling medium is forced to circulate in the clamping 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 forming piece, avoiding the erosion, corrosion or pollution of the cooling medium to the surface of the forming piece, ensuring that the heat is uniformly taken away from all directions, avoiding the internal stress, deformation or cracks caused by local rapid cooling, and ensuring the dimensional accuracy and internal quality of the forming piece.

[0036] In the embodiment, as Figure 1 , Figure 5 , Figure 6 and Figure 9 shown, the top of the outer tank body 11 is provided with an upper box body 3, the upper box body 3 is communicated with a liquid supply pipe 6, the liquid supply pipe 6 is provided with a control valve for adjusting the flow of the cooling medium. The bottom of the upper box body 3 and the top of the side wall are respectively communicated with the clamping cavity 17 through the second connecting pipe 13 and the first connecting pipe 12; the upper box body 3 is connected with a gas supply pipe 7, the gas supply pipe 7 is connected with a gas injection mechanism 5, and the gas injection mechanism 5 is arranged at the front end opening of the outer tank body 11.

[0037] In addition, the inner cavity of the upper box 3 is transversely provided with a screen 21 made of stainless steel. After the water is injected into the upper box 3 through the liquid supply pipe 6, the cooling liquid in the lower partition cavity 23 may splash due to turbulent flow or pressure fluctuation, at which time the screen 21 prevents the water from splashing into the upper partition cavity 22, avoiding the water from splashing into the gas supply pipe 7. The screen 21 divides the inner cavity of the upper box 3 into the upper partition cavity 22 and the lower partition cavity 23, and the liquid supply pipe 6 is connected to the end of the upper box 3, penetrates the screen 21 and is inserted into the lower partition cavity 23. Further, the bottom of the outer tank 11 is provided with a lower box 10, which is provided with a gas supply mechanism and a liquid outlet pipe 20, and the top and sidewall top of the lower box 10 are respectively connected to the clamping cavity 17 through the fourth connecting pipe 15 and the third connecting pipe 14.

[0038] As shown in Figure 10 , the liquid supply pipe 6, the lower partition cavity 23, the second connecting pipe 13, the clamping cavity 17, the fourth connecting pipe 15 and the lower box 10 form a flow path of the cooling medium of the liquid, and the cooling water is injected into the clamping cavity 17 through the second connecting pipe 13. Under the action of gravity, the liquid flows downward along the wall surface of the inner tank 16 in the clamping cavity 17, forming a liquid film wrapped on the outer wall surface of the inner tank 16. This "liquid film" flow mode enables the cooling liquid to fully and continuously contact the outer wall of the inner tank 16, and through forced convection heat exchange, efficiently removes the heat of the inner tank 16 and the internal molded parts. In addition, the liquid after heat exchange and cooling flows into the lower box 10 through the fourth connecting pipe 15 for recovery.

[0039] Further, as shown in Figure 11 , the gas supply mechanism, the lower box 10, the third connecting pipe 14, the clamping cavity 17, the first connecting pipe 12, the upper partition cavity 22, the gas supply pipe 7 and the gas injection mechanism 5 form a flow path of the gas, and 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 to contact the downward flowing liquid in counterflow, so that the gas temperature gradually decreases and becomes a gas cooling medium, which then enters the gas injection mechanism 5 through the first connecting pipe 12, the upper partition cavity 22 and the gas supply pipe 7, and is directly injected into the inner tank 16 to perform gas cooling by gas injection on the castings in the inner tank 16. This gas injection cooling method has fast cooling speed, strong penetration and directly acts on the surface of the castings, which makes up for the deficiency that liquid cooling cannot reach the internal area.

[0040] Further, the circumferential outer wall of the inner tank 16 is provided with a plurality of fins 18 at equal intervals on the portion located in the clamping cavity 17. When the cooling liquid flows downward, the fins 18 block the flow, and the flow around the fins 18, impingement, separation and reattachment and other phenomena occur at the fins 18, effectively destroying the laminar boundary layer close to the wall, slowing down the liquid flow speed, increasing the contact time with the inner tank 16, and forcing the low-temperature liquid in the main flow area to mix with the liquid in the boundary layer that has been heated, thereby improving the heat exchange effect. In addition, when the temperature of the cast-in-place member in the inner tank 16 is transmitted through the inner tank 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.

[0041] In the present embodiment, as shown in Figure 1 and Figure 5 , 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 tank body 10.

[0042] Specifically, the gas generating mechanism includes a gas compressor 8, and the gas outlet end of the gas compressor 8 is connected to the aeration mechanism 19 through a gas supply pipe 9. In implementation, the gas compressor 8 works to supply high-pressure gas into the aeration mechanism 19 through the gas supply pipe 9, and the aeration mechanism 19 uniformly distributes the gas in the form of small bubbles in the lower tank body 10. The gas is heat-exchanged with the heated water received by the lower tank body 10, thereby reducing the temperature of the water in the lower tank body 10. The water in the lower tank body 10 is then transported to the heat exchanger after the temperature is reduced, and the water is heat-exchanged by the heat exchanger and then directly connected to the liquid supply pipe 6 for circulation. The heat-exchanged gas is heat-exchanged again when rising in the clamping cavity 17, and then sprayed into the inner tank 16 by the gas injection mechanism 5 to blow the cast-in-place member. The temperature of the flowing gas wrapped around the cast-in-place member is discharged from the open end of the outer tank 11.

[0043] In some embodiments, as shown in Figure 7 and Figure 8 , the aeration mechanism 19 includes a gas chamber 191, a plurality of aeration pipes 192, and a plurality of openings 193 uniformly distributed on each aeration pipe 192. The gas chamber 191 is fixed inside the lower tank body 10, the gas supply pipe 9 is in communication with the gas chamber 191, and the aeration pipes 192 are arranged above the gas chamber 191. The high-pressure gas generated by the gas compressor 8 is supplied into the gas chamber 191 through the gas supply pipe 9, the pressure pulsation of the gas is effectively absorbed, a relatively stable pressure field is formed in the gas chamber 191, and the high-pressure gas is distributed into each aeration pipe 192, thereby avoiding the problem of excessive aeration in some areas and "aeration blind area" in some areas due to uneven gas supply from the source. The gas is then sprayed into the lower tank body 10 through the aeration pipes 192, so that the gas becomes uniform bubbles and is in contact with the recovered hot liquid in the lower tank body 10 for heat exchange, thereby reducing the temperature of the liquid to the maximum extent.

[0044] Further, each of the openings 193 is provided with a one-way valve 194, so that gas can only be sprayed outwards, preventing liquid from entering the aeration pipe 192. In addition, the one-way valve 194 is provided with a gas outlet pipe 195, the outer wall of the gas outlet pipe 195 is provided with gas outlet openings 196, and the top of the gas outlet pipe 195 is fixed with a baffle 197, the baffle 197 is provided with a plurality of gas distribution holes 198. The gas is sprayed out through the plurality of gas outlet openings 196, and then floats upwards to contact the gas distribution holes 198 on the baffle 197, which has the effect of "shearing" and "collision breaking" on the gas bubbles. When the gas bubbles hit the baffle, the kinetic energy is absorbed, and the size is further torn and broken, so that the gas bubbles are further decomposed into small bubbles, further enhancing the contact effect of gas and liquid and the heat exchange effect.

[0045] As shown in Figures 2-4 the embodiment, the gas injection mechanism 5 includes a fixed plate 501, a swing arm, a push rod, and a gas injection hose 506. The fixed plate 501 is fixed at the top of the front end opening of the outer tank body 11, the swing arm is arranged on the fixed plate 501, the push rod is arranged between the swing arm and the fixed plate 501, one end of the gas injection hose 506 is connected to the gas supply pipe 7, and the other end is connected with a gas injection nozzle 507. When the cover 4 is closed, the push rod drives the swing arm to rise, so that the swing arm and the gas injection nozzle 507 are higher than the front end opening of the outer tank body 11, facilitating the opening and closing of the cover 4. When it is necessary to cool the cast product in the inner tank body 16, the push rod drives the swing arm to descend, so that the swing arm drives the gas injection nozzle 507 to extend into the front end opening of the outer tank body 11, so that the sprayed gas acts on the cast product in the inner tank body 16 to perform the cooling work.

[0046] For example, the swing arm includes a first arm rod 503 and a second arm rod 505, one end of the first arm rod 503 is hinged to the bottom of the fixed plate 501, and the other end is hinged to one end of the second arm rod 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 part of the first arm rod 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 part of the second arm rod 505.

[0047] When the push rod drives the swing arm to rise, the first push rod 502 retracts to drive the hinged end of the first arm rod 503 and the second arm rod 505 to rise. In addition, the second push rod 504 advances to drive the second arm rod 505 to rise, thereby driving the gas injection nozzle 507 to rise. Conversely, when it is necessary to cool the cast product in the inner tank body 16, the first push rod 502 advances and the second push rod 504 retracts to drive the first arm rod 503 and the second arm rod 505 to descend, thereby driving the gas injection nozzle 507 to flip and extend into the front end opening of the outer tank body 11.

[0048] Working principle: melt material is injected into the inner tank 16, the cover 4 is closed; the driving device 2 drives the inner tank 16 to rotate in the outer tank 11, and the melt material is shaped along the inner wall of the inner tank 16 under the action of centrifugal force; at this time, the gap 17 between the outer tank 11 and the inner tank 16 temporarily serves as a heat preservation space to ensure the stability of the forming process.

[0049] The cooling stage is as follows:

[0050] Liquid cooling (overall cooling): liquid cooling medium (such as cooling water) enters the lower partition cavity 23 of the upper box body 3 through the liquid supply pipe 6 (the separation net 21 prevents liquid from splashing into the upper partition cavity 22); the cooling liquid flows into the gap 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 16, forms a uniform liquid film and flows downward along the wall, fully contacts the high-temperature inner tank 16, and quickly removes heat through forced convection heat exchange to achieve overall cooling of the casting; the heated 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 and recovery.

[0051] Gas cooling (local precise cooling): the gas compressor 8 of the gas supply mechanism produces high-pressure gas, which is sent into the aeration mechanism 19 in the lower box body 10 through the gas supply pipe 9; the aeration mechanism 19 stabilizes the gas pressure through the gas chamber 191, and then disperses the gas into small bubbles through the openings 193 of the aeration pipe 192 (with a one-way valve 194 to prevent liquid backflow); the bubbles are further broken by the baffle 197 after being sprayed out of the gas outlet opening 196 of the gas outlet pipe 195, and fully exchange heat with the hot liquid recovered in the lower box body 10 to reduce the temperature of the gas;

[0052] The cooled gas enters the gap 17 through the third connecting pipe 14 of the side wall of the lower box body 10, and forms a countercurrent contact with the downward flowing liquid, and after further cooling, enters the upper partition cavity 22 of the upper box body 3 through the first connecting pipe 12 at the top of the side wall of the outer tank 11.

[0053] The low-temperature gas is delivered to the gas injection mechanism 5 through the gas supply pipe 7, and the position of the gas injection nozzle 507 is adjusted by the first arm lever 503, the second arm lever 505, and the first push rod 502, the second push rod 504 (rises to avoid interference when the cover 4 is closed, and descends to extend into the inner tank 16 during cooling), and the gas is precisely injected into the inner tank 16 to locally target cool the key parts of the casting.

[0054] Liquid cooling achieves overall rapid cooling of the casting, gas cooling makes up for the insufficient local cooling, and the two media cooperatively solve the uneven problem of 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 circulation and utilization of the cooling medium, and taking into account high efficiency and energy saving and environmental protection.
