Description

Technical Field

[0001] The invention belongs to the technical field of centrifugal casting machines, in particular to a centrifugal rotary casting machine. Background Art

[0002] Centrifugal rotary casting machine, also known as centrifuge, is a machine that uses centrifugal force to fill liquid metal in a rotating mold and solidify it into a casting during the casting process. Its basic principle is to pour molten metal into a high-speed rotating metal mold. Under the action of centrifugal force, the metal liquid is evenly coated along the inner wall of the mold and cooled and solidified into the desired casting shape. The metal melting temperature in the casting pot is monitored and controlled in real time by an infrared thermometer to ensure that the molten metal is cast within the optimal temperature range, thereby improving the quality and consistency of the casting.

[0003] During the centrifugal casting process, liquid metal is injected into a high-speed rotating mold. Due to the solidification and friction of the molten metal, a large amount of heat will be generated. If this heat cannot be dissipated in time, the internal temperature of the casting will be too high, resulting in defects such as cracks, deformation, and coarse structure in the casting, which seriously affects the quality and service life of the casting. Therefore, in the prior art, a spray device is usually used to cool the mold to ensure the molding quality of the casting. However, when the existing spray device is used,

[0004] Impurities such as metal oxides, oil, and sand may remain on the mold surface. Therefore, when spray cooling is used, these impurities may be washed down and mixed into the cooling water. If the water is recycled at this time, the impurities will accumulate in the water, thereby clogging the pipes and nozzles of the cooling system and other components, affecting the cooling effect and even causing equipment failure.

[0005] To this end, the present invention provides a centrifugal rotary casting machine to improve the cooling effect of the mold. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 9 As shown, a centrifugal rotary casting machine according to an embodiment of the present invention comprises a casting machine body 1, a casting box 2, an infrared thermometer 3, a mold 4 and a spray pipe 6;

[0039] A metal liquefaction device is provided on the top of the mold 4 to melt the metal into liquid. The molten metal is poured into the mold 4 by rotating the metal liquefaction device, and the centrifugal device provided at the bottom of the mold 4 assists in the molding of the molten metal. The temperature can be detected by the infrared thermometer 3 provided on the top.

[0040] The spray pipe 6 can impact the outer wall of the mold 4 to cool the mold 4, effectively avoiding the problem that the heat cannot be dissipated in time, thereby affecting the organizational structure and performance of the casting.

[0041] A water tank 5 is provided inside the casting machine body 1, a guide pipe 30 is fixedly installed on the top of the water tank 5, the other end of the guide pipe 30 is communicated with the inner cavity of the casting box 2, and a conveying component is provided inside the casting machine body 1 for conveying the water in the water tank 5 to the inside of the spray pipe 6;

[0042] When the spray pipe 6 sprays the mold 4, the water at this time will fall into the bottom end of the casting box 2 and flow into the interior of the water tank 5 through the provided guide pipe 30. The water entering the water tank 5 will be transported back to the interior of the spray pipe 6 through the provided conveying assembly to spray the mold 4. The water can be recycled and the problem of water resource waste can be effectively reduced.

[0043] An air nozzle 7 is provided inside the water tank 5. The air nozzle 7 is provided below the liquid level of the water tank 5. An air nozzle hole 35 is provided at the top of the air nozzle 7. The gas is discharged through the air nozzle hole 35, and the impurities are adsorbed and taken out by the bubbles moving in the water body.

[0044] The air nozzle 7 is a U-shaped tube, which is arranged at the bottom of the water tank 5. A plurality of air nozzle holes 35 are provided, and the plurality of air nozzle holes 35 are evenly arranged at the top of the air nozzle 7. When gas is transported into the air nozzle 7, the gas will be ejected through the plurality of air nozzle holes 35 provided at the top of the air nozzle 7. At this time, the gas will float upward from the bottom of the water body of the water tank 5. During the floating process, the air bubbles will disturb the water body around them, forming a local water flow. Although this water flow may be weak, it will still promote nearby impurities and make them move. At the same time, the impurities will also adhere to the bubbles (for example, surface tension and charge attraction). Then, when the bubbles float, they will drive these impurities to move together, thereby bringing the impurities in the water body to the surface.

[0045] A steam recovery assembly is provided inside the casting machine body 1, which is used to collect the water vapor used by the spray pipe 6 to cool the mold 4 and transmit it to the air spray pipe 7;

[0046] When the spray pipe 6 cools the mold 4, the high temperature on the surface of the mold 4 can quickly gasify the water and turn it into water vapor. At this time, the water vapor can be transported to the inside of the air nozzle 7 through the steam recovery component and sprayed out through the air nozzle hole 35, so that bubbles appear in the water and float up. At the same time, it can also assist the liquefaction of water vapor, further improving the utilization efficiency of the water.

[0047] The water tank 5 is provided with a gas spray assembly inside and located above the liquid surface, and is used to drive the water surface to flow by spraying gas;

[0048] When bubbles float up in the water and bring impurities to the surface of the water, the air spray assembly can be used to spray the liquid surface of the water, causing the liquid surface to fluctuate, and the liquid surface can fluctuate in a direction away from the air spray assembly, while also blowing away the impurities.

[0049] A collecting net 34 is arranged at one end of the water tank 5 away from the air spray assembly. The collecting net 34 is arranged with an opening at one end facing the air spray assembly to absorb impurities floating on the surface of the water body through the flow of the water body.

[0050] The impurities that fluctuate toward the collecting net 34 can be collected by the provided collecting net 34. The fluctuation of the water body drives the impurities and can directly enter the interior of the collecting net 34 through the opening on the collecting net 34. The collected impurities can be processed by simply taking the collecting net 34 out of the water tank 5.

[0051] This is a preferred embodiment of the present invention. The conveying assembly includes a water pump 27, a water suction pipe 29 and a water outlet pipe 28. The water pump 27 is fixedly installed on the top of the water tank 5. One end of the water suction pipe 29 is fixedly connected to the input end of the water pump 27, and the other end extends to the interior of the water tank 5. One end of the water outlet pipe 28 is fixedly connected to the output end of the water pump 27, and the other end extends to the interior of the spray pipe 6.

[0052] By starting the water pump 27, the water in the water tank 5 can be pumped out through the pumping pipe 29, and the water can be transported to the inside of the spray pipe 6 through the outlet pipe 28, thereby realizing water circulation spraying and saving water resources.

[0053] It is a preferred embodiment of the present invention, and the steam recovery component includes a first box 8, an air intake pipe 12 and a steam recovery pipe 11. The first box 8 is fixedly installed inside the casting machine body 1, one end of the steam recovery pipe 11 extends to the inside of the first box 8, and the other end extends to the inside of the water tank 5 and is connected with the air nozzle 7, and one end of the air intake pipe 12 extends to the inside of the first box 8, and the other end extends to the inside of the casting box 2.

[0054] When the spray pipe 6 sprays the mold 4 (the feed port on the top of the casting box 2 needs to be closed at this time), the interior of the casting box 2 will be filled with water vapor. The water vapor can enter the interior of the first box 8 through the set air inlet pipe 12, and then enter the interior of the air nozzle pipe 7 through the steam recovery pipe 11 connected to the first box 8, and finally be discharged through the air nozzle hole 35, thereby achieving the effect of floating bubbles in the water body and taking out impurities in the water body.

[0055] It is a preferred embodiment of the present invention. The air spray assembly includes a piston cylinder 23, a first piston 24, a first tube 25, a second tube 26, an air collecting box 36 and an air nozzle 37. The piston cylinder 23 is fixedly installed inside the casting machine body 1, the first piston 24 is slidably installed inside the piston cylinder 23, the air collecting box 36 is fixedly installed at one end of the water tank 5 away from the collecting net 34, the air nozzle 37 is fixedly installed on the air collecting box 36, the first tube 25 and the second tube 26 are both connected to the piston cylinder 23, the other end of the first tube 25 extends to the inside of the air collecting box 36, and the other end of the second tube 26 extends out of the outer wall of the casting machine body 1, and a one-way valve is provided on the first tube 25 and the second tube 26.

[0056] The one-way valve disposed on the first tube 25 can prevent gas from entering the piston cylinder 23 , and the one-way valve disposed on the second tube 26 can prevent gas on the piston cylinder 23 from flowing out of the second tube 26 .

[0057] When the first piston 24 slides upward inside the piston cylinder 23, the outside gas can be sucked into the interior of the piston cylinder 23 through the second tube 26. When the first piston 24 slides downward inside the piston cylinder 23, the gas entering the piston cylinder 23 can be transported to the interior of the air collecting box 36 through the first tube 25. As the air pressure inside the air collecting box 36 increases, the gas in the air collecting box 36 can finally be ejected through the set air nozzle 37. There are multiple air nozzles 37, and the openings of the multiple air nozzles 37 are inclined, which can effectively blow the surface of the water in the water tank 5, so that the water drives the impurities to move toward the collection net 34.

[0058] This is a preferred embodiment of the present invention. A second box 13 is fixedly installed inside the casting machine body 1, a second piston 14 is slidably installed inside the second box 13, a transmission rod 15 is fixedly installed at one end of the second piston 14, and the transmission rod 15 extends from one end of the second piston 14 to the interior of the piston cylinder 23 and is fixedly connected to the first piston 24.

[0059] The second box 13 fits with the first box 8. When the second piston 14 inside the second box 13 slides, the first piston 24 can be driven to slide synchronously through the transmission rod 15. Therefore, when the second piston 14 in the second box 13 slides upward, the first piston 24 will also slide upward inside the piston cylinder 23. When the second piston 14 in the second box 13 slides downward, it will drive the first piston 24 to slide downward inside the piston cylinder 23. By controlling the reciprocating sliding of the second piston 14, the first piston 24 can be driven to slide reciprocally inside the piston cylinder 23, thereby achieving the effect of continuously inflating the air collecting box 36.

[0060] This is a preferred embodiment of the present invention, an air blocking frame 9 is slidably installed inside the first box 8, a connecting rod 10 is fixedly installed at one end of the air blocking frame 9, one end of the connecting rod 10 extends out of the outer wall of the air blocking frame 9 and is rotatably installed with a first lever 17 and a second lever 18, and the first lever 17 and the second lever 18 are both rotatably installed inside the casting machine body 1;

[0061] A shift block 16 is fixedly mounted on the outer wall of the transmission rod 15 , and the shift block 16 is located between the first shift rod 17 and the second shift rod 18 .

[0062] The end of the air blocking frame 9 facing the steam recovery pipe 11 is not blocked. No matter how the air blocking frame 9 slides inside the first box 8, the steam recovery pipe 11 is always located inside the air blocking frame 9. When the second piston 14 slides downward inside the second box 13, the second piston 14 will drive the transmission rod 15 and the shift block 16 to slide downward, and at the same time push one end of the second shift rod 18 to make it rotate counterclockwise inside the casting machine body 1. At this time, the other end of the second shift rod 18 will push the connecting rod 10 upward, driving the air blocking frame 9 to slide upward inside the first box 8.

[0063] When the second piston 14 slides upward inside the second box 13, it will drive the transmission rod 15 and the shift block 16 to slide upward, and push the first shift rod 17 upward. At this time, the first shift rod 17 will rotate clockwise inside the casting machine body 1, and drive the connecting rod 10 to slide downward, so that the air blocking frame 9 slides downward inside the first box 8.

[0064] This is a preferred embodiment of the present invention. The first box 8 is provided with a first air port 19 and a second air port 22. The second box 13 is provided with a third air port 20 and a fourth air port 21. The first air port 19 corresponds to the third air port 20, and the second air port 22 corresponds to the fourth air port 21.

[0065] The air blocking frame 9 is also opened in the direction of the first air port 19. When the air blocking frame 9 slides to the top of the first box 8, the second box 13 is connected to the steam recovery pipe 11 in the air blocking frame 9 through the first air port 19 and the third air port 20. When the air blocking frame 9 is below the first box 8, the second box 13 is connected to the steam recovery pipe 11 inside the air blocking frame 9 through the second air port 22 and the fourth air port 21.

[0066] When water vapor is produced in the casting box 2, it will enter the interior of the first box 8 through the air inlet pipe 12. When the air blocking frame 9 is located below the first box 8, the water vapor will enter the interior of the second box 13 through the first air port 19 and the third air port 20. As the water vapor is pressurized, it will push the second piston 14 to slide downward inside the second box 13. At the same time, the transmission rod 15 will drive the shift block 16 to slide downward, and press the second shift rod 18 to make it rotate counterclockwise, so that the connecting rod 10 drives the air blocking frame 9 to slide upward inside the first box 8 until the air blocking frame 9 covers the first air port 19 and the third air port 20. At this time, the water vapor entering the first box 8 will enter the interior of the second box 13 through the second air port 22 and the fourth air port 21, and press from the bottom of the second piston 14 to make the second piston 14 slide upward inside the second box 13. The water vapor above the second piston 14 will enter the interior of the air nozzle 7 from the steam recovery pipe 11 through the first air port 19 and the third air port 20. When the second piston 14 slides upward, it will drive the shift block 16 to press the first shift rod 17 to rotate clockwise, so that the connecting rod 10 drives the air blocking frame 9 to slide downward, and covers the second air port 22 and the fourth air port 21. At this time, the water vapor enters the interior of the second box 13 through the first air port 19 and the third air port 20, and pushes the second piston 14 to slide downward. At this time, the water vapor below the second piston 14 enters the steam recovery pipe 11 and the interior of the air nozzle 7 through the second air port 22 and the fourth air port 21. The first piston 24 can be controlled to slide back and forth inside the piston cylinder 23 through reciprocating operation, effectively utilizing water vapor as kinetic energy to achieve blowing on the water surface and improve the treatment of impurities in the water.

[0067] This is a preferred embodiment of the present invention. A guide plate 32 is slidably installed inside the water tank 5 , and an air bag 33 is fixedly installed at the bottom end of the guide plate 32 .

[0068] The guide plate 32 is arranged at an angle. The plane behind the inclined surface of the guide plate 32 can block the backflow generated by the drifting water hitting the inner wall of the water tank 5. The air bag 33 arranged at the bottom of the guide plate 32 can keep the guide plate 32 floating on the water surface at all times, thereby improving the effect of blocking the backflow caused by the impact of the water body.

[0069] This is a preferred embodiment of the present invention. A semiconductor cooling sheet 31 is provided inside the water tank 5 to cool the water temperature of the water tank 5 .

[0070] The semiconductor refrigeration sheet 31 can be set to cool the water in the water tank 5, and the stability of cooling the mold 4 can be ensured when the water is circulated. At the same time, the water vapor can be condensed and liquefied by cooling, further reducing the waste of water resources. The cold end of the semiconductor refrigeration sheet 31 needs to face the inside of the water tank 5.

[0071] Working principle: by controlling the first piston 24 to slide upward inside the piston cylinder 23, the outside gas can be sucked into the interior of the piston cylinder 23 through the second tube 26; when the first piston 24 slides downward inside the piston cylinder 23, the gas entering the piston cylinder 23 can be transported to the interior of the gas collecting box 36 through the first tube 25, and finally sprayed out through the set gas nozzle 37, which can effectively blow the surface of the water in the water tank 5, so that the water drives the impurities to move toward the collection net 34, which is convenient for cleaning the impurities in the water and effectively protects the service life of the spray pipe 6.

[0072] By starting the water pump 27, the water in the water tank 5 can be pumped out through the water pumping pipe 29, and the water can be transported to the inside of the spray pipe 6 through the water outlet pipe 28 to spray the mold 4. At this time, the water vapor produced will enter the inside of the first box 8 through the air inlet pipe 12, and enter the inside of the second box 13 through the first air port 19 and the third air port 20, pushing the second piston 14 to slide downward in the second box 13, so that the transmission rod 15 drives the shift block 16 to slide downward, and presses the second shift rod 18 to make it rotate counterclockwise, so that the connecting rod 10 drives the air blocking frame 9 to slide upward in the first box 8 to block the first air port 19 and the third air port 20. At this time, water vapor will enter the second box 13 through the second air port 22 and the fourth air port 21 and be below the second piston 14, and press it upward to make it slide upward. At the same time, water vapor enters the steam recovery pipe 11 through the first air port 19 and the third air port 20. By repeating the above operations, the first piston 24 can be controlled to slide back and forth inside the piston cylinder 23, and water vapor can be discharged from the bottom of the water body, and impurities in the water can be brought to the surface of the water through the floating of bubbles. The air spray component can be used to further improve the cleaning effect on the water body, and at the same time, the water vapor can be converted into kinetic energy to drive the first piston 24 to slide, thereby further improving the utilization of resources.
