Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ingot cooling, in particular to an environmentally friendly aluminum ingot water circulation cooling device. Background Art

[0002] Aluminum alloy is an alloy made by adding other elements in accordance with international standards or special requirements to improve the casting, chemical and physical properties of pure aluminum. At present, in the production process of aluminum ingots, the die-cast aluminum alloy raw materials are first cleaned and dried, and then the aluminum blocks are melted into molten aluminum in a melting furnace. The molten aluminum is injected into the aluminum ingot mold cavity through an ingot casting machine and cooled to form. Finally, the formed high-strength, tough and lightweight die-cast aluminum alloy ingot is removed from the mold.

[0003] There are many existing technologies for cooling devices, such as:

[0004] Chinese patent publication number CN112296280A discloses the technical field of aluminum ingot production, and discloses a cooling device for aluminum ingot production, including a water tank and a mold body, the top of the water tank is fixedly connected to a cooling trough body, the left side of the cooling trough body is fixedly connected to a connecting plate, the left side of the connecting plate is fixedly connected to a driving motor, the output shaft of the driving motor is fixedly connected to a threaded rod, the outer side of the threaded rod is threadedly connected to a lifting plate, the right side of the water tank is fixedly connected to a booster pump, the left and right sides of the mold body are fixedly connected to brackets, the top of the bracket on the right side is fixedly connected to a fixing frame, the left side of the fixing frame is fixedly connected to a spray head, the left side of the water tank is fixedly connected to an overflow pipe, the right side of the booster pump is fixedly connected to a water pipe, and the right side of the cooling trough body is fixedly connected to a water pump.

[0005] However, there are still some problems in actual use:

[0006] 1. During the use of traditional cooling devices, the aluminum mold will be heated to a high temperature when pouring aluminum liquid. During the cooling process, especially during spraying or forced cooling, there will be adhesion between the mold and the aluminum ingot, which makes it difficult to demould after cooling is completed, affecting processing efficiency.

[0007] 2. During the cooling process of aluminum ingots, steam diffusion will cause the surrounding environment to be in a high-humidity and high-temperature state for a long time. The high-temperature and high-humidity environment will cause the operator's body temperature to increase significantly (especially in summer), which can easily cause fatigue and heatstroke to the operators.

[0008] In view of this, we propose an environmentally friendly aluminum ingot water circulation cooling device. Summary of the Invention

When the screw rod rotates, it drives the placement plate to move horizontally in the axial direction.

[0012] As a further improvement of the present technical solution, a through hole is provided on the surface of the placement plate, and the through hole is used to accelerate air convection for the aluminum ingot mold placed on the surface of the placement plate, and the coolant during spraying of the aluminum ingot mold flows out through the through hole.

[0013] As a further improvement of the present technical solution, the demoulding assembly includes a vertical plate arranged on one side of the ramp plate, a turntable is provided on the end face of the vertical plate for rotation, a convex column is provided on the surface of the turntable, a gear slide is provided on the surface of the convex column for sliding, the gear slide rotates near the bottom at the end of the vertical plate, a rack is provided at the bottom of the gear slide, and when the gear slide rotates, it drives the rack to move in the horizontal direction.

When the rack drives the base plate to move horizontally, the compression spring knocks on the side wall of the aluminum ingot mold.

[0015] As a further improvement of this technical solution, a connecting rod is provided on the back of the turntable, which passes through the water storage pipe and has turbine blades at the end. When the water pump is pumping water, the water flowing through the water storage pipe impacts the turbine blades to cause them to rotate.

[0016] As a further improvement of the present technical solution, a cooling component is provided on the outside of the cooling tank, and the cooling component is used to perform secondary cooling on the cooling water flowing into the cooling tank.

[0017] As a further improvement of the present technical solution, the cooling component includes a fixed frame arranged outside the cooling tank, the end surface of the fixed frame is provided with a through slot, an exhaust fan is provided in the through slot, and the exhaust fan blows air to the outside.

[0018] As a further improvement of the present technical solution, a corrugated plate is provided inside the fixed frame. The corrugated plate is corrugated and made of metal.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this environmentally friendly aluminum ingot water circulation cooling device, the motor output shaft is controlled to drive the screw to rotate. When the screw rotates, it drives the placement plate to move horizontally on its surface. The placement plate drives the aluminum ingot mold to move under the shower head. The shower head sprays coolant on the aluminum ingot mold to quickly cool it down. At the same time, since through holes are opened on the surface of the placement plate, its bottom is in an open state when cooling the aluminum ingot mold, which increases the contact area with the air, thereby improving the cooling speed of the aluminum liquid mold.

[0021] 2. In the environmentally friendly aluminum ingot water circulation cooling device, when water is pumped by a water pump to spray and cool the aluminum ingot mold, the water impacts the turbine blades when passing through the water storage pipe to make them rotate. When the turbine blades rotate, the turntable is driven to rotate through the connecting rod, and the convex column is driven to rotate during the rotation of the turntable. When the convex column rotates, it drives the gear slide to rotate. When the gear slide rotates, it drives the rack to move horizontally. When the rack moves, it drives the base plate to move in the horizontal direction. The impact block provided at the end of the base plate reciprocates and knocks the outer wall of the aluminum ingot mold, weakening the bonding force of the contact surface through vibration. The vibration energy can weaken the tiny welds of metallurgical bonding, so that the adhesion parts are separated due to stress concentration, which can not only protect the mold and casting, but also improve the demoulding efficiency.

[0022] 3. In this environmentally friendly aluminum ingot water circulation cooling device, during the cooling operation, the exhaust fan is used to blow air to the outside of the fixed frame to accelerate the interaction between the air and the inside of the fixed frame. When the coolant is sprayed through the shower head, air convection blows the coolant to quickly reduce the temperature of the coolant, thereby improving the cooling efficiency of the aluminum ingot mold.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] The purpose of this embodiment is to provide an environmentally friendly aluminum ingot water circulation cooling device. Figure 1-Figure 7 As shown, it includes a coolant tank 100, a frame 101 is provided on the top of the coolant tank 100, a spray assembly 200 is provided on the top of the frame 101, and the spray assembly 200 includes a water pump 201 provided on the top of the frame 101. The water inlet and outlet of the water pump 201 are respectively connected to a water inlet pipe 202 and a water outlet pipe 204. A water storage pipe 203 is provided between the water inlet pipe 202 and the water inlet. A filter disc 205 is provided at the bottom of the water inlet pipe 202. A cooling tank 206 is provided below the frame 101. A shower head 207 is provided at the bottom of the cooling trough 206, and the outlet pipe 204 outputs the coolant to the inside of the cooling trough 206. A ramp plate 102 is provided on the surface of the coolant tank 100, and a moving component 300 is provided on the surface of the ramp plate 102. The moving component 300 is used to place the aluminum ingot mold and drive it to move below the shower head 207. A demolding component 400 is provided on one side of the ramp plate 102. The demolding component 400 is used to automatically demold the aluminum ingot mold during the spraying process to separate the aluminum ingot from the mold.

[0039] Taking into account that the surface temperature of the aluminum ingot mold is high after casting, it is easy to cause burns during the process of transferring it to the cooling table. Therefore, the moving component 300 includes a motor 301 arranged at the end of the ramp plate 102, and a screw rod 302 is provided at the output end of the motor 301. A placement plate 303 is provided on the surface of the screw rod 302. When the screw rod 302 rotates, it drives the placement plate 303 to move horizontally in the axial direction. A through hole 304 is opened on the surface of the placement plate 303. The through hole 304 is used to accelerate air convection for the aluminum ingot mold placed on the surface of the placement plate 303. The coolant during spraying of the aluminum ingot mold passes through the through hole 304 flows out, and the cast aluminum ingot mold is placed on the surface of the placement plate 303. The output shaft of the control motor 301 drives the screw 302 to rotate. When the screw 302 rotates, it drives the placement plate 303 to move horizontally on its surface. The placement plate 303 drives the aluminum ingot mold to move under the shower head 207. The shower head 207 sprays coolant on the aluminum ingot mold to quickly cool it down. At the same time, since a through hole 304 is opened on the surface of the placement plate 303, its bottom is in an open state when the aluminum ingot mold is cooled, which increases the contact area with the air, thereby improving the cooling speed of the aluminum liquid mold.

[0040] The aluminum liquid mold will be heated to a high temperature when pouring aluminum liquid. During the cooling process, especially during spraying or forced cooling, there will be a problem of adhesion between the mold and the aluminum ingot, which makes it inconvenient to demould after cooling is completed, affecting the processing efficiency. Therefore, the demoulding component 400 includes a vertical plate 401 arranged on one side of the ramp plate 102, and a turntable 402 is provided on the end surface of the vertical plate 401 for rotation. A convex column is provided on the surface of the turntable 402, and a gear slide 403 is provided on the surface of the convex column for sliding. The gear slide 403 rotates near the bottom at the end of the vertical plate 401, and a rack 405 is provided at the bottom of the gear slide 403. When the gear slide 403 rotates, it drives the rack 405 to move horizontally. A base plate 406 is provided at the end of the rack 405, and a push rod 407 is provided for sliding on the end surface. A compression spring 409 is provided at the end of the push rod 407. A collision block 408 is provided between the base plate 406 and the compression spring 409. When the rack 405 drives the base plate 406 to move horizontally, the base plate 406 is provided at the end of the rack 405. The end surface is provided with a push rod 407 for sliding, and a compression spring 409 is provided at the end of the push rod 407. A collision block 408 is provided between the base plate 406 and the compression spring 409. When the rack 405 drives the base plate 406 to move horizontally, the compression spring 409 knocks the side wall of the aluminum ingot mold. The compression spring 409 knocks the side wall of the aluminum ingot mold. In the process of spraying and cooling the aluminum material, by rotating the turntable 402 on the surface of the vertical plate 401, the turntable 402 drives the convex column to rotate during the rotation of the turntable 402. When the convex column rotates, it drives the gear slide 403 to rotate. When the gear slide 403 rotates, it drives the rack 405 to move horizontally. When the rack 405 moves, it drives the base plate 406 to move horizontally. The collision block 408 provided at the end of the base plate 406 knocks back and forth on the outer wall of the aluminum ingot mold, weakening the bonding force of the contact surface through vibration. The vibration energy can weaken the tiny welds of metallurgical bonding, so that the adhesion parts are separated due to stress concentration, which can protect the mold and casting and improve the demoulding efficiency.

[0041] In order to avoid adhesion between the aluminum ingot and the mold, the aluminum ingot mold is lightly tapped during the cooling process. Since the operator needs to rotate the vertical plate 401, the labor intensity of the operator is increased. Therefore, a connecting rod is provided on the back of the turntable 402, which passes through the water storage pipe 203 and has a turbine blade 404 at the end. When the water pump 201 is pumping water, the water flowing through the water storage pipe 203 impacts the turbine blade 404 to make it rotate. When the water pump 201 is pumping water to spray and cool the aluminum ingot mold, water is extracted through the water inlet pipe 202. When the water passes through the water storage pipe 203, it impacts the turbine blade 404 to make it rotate. When the turbine blade 404 rotates, the turntable 402 is driven to rotate through the connecting rod, thereby driving the impact block 408 to reciprocate and impact the side wall of the mold, reducing the labor intensity of the operator.

[0042] Since the coolant in the coolant tank 100 is circulated, the temperature of the coolant gradually increases, affecting the cooling efficiency. Therefore, a cooling component 500 is provided on the outside of the cooling tank 206. The cooling component 500 is used to perform secondary cooling on the cooling water flowing into the cooling tank 206. The cooling component 500 includes a fixed frame 501 provided on the outside of the cooling tank 206. A through groove is provided on the end face of the fixed frame 501. An exhaust fan 502 is provided in the through groove. The exhaust fan 502 blows air to the outside. During the cooling operation, the exhaust fan 502 blows air to the outside of the fixed frame 501 to accelerate the interaction between the air and the inside of the fixed frame 501. When the coolant is sprayed through the shower head 207, the air convection blows the coolant to quickly reduce the cooling temperature, thereby improving the cooling efficiency of the aluminum ingot mold.

[0043] During the cooling process of the aluminum ingot, steam diffusion will cause the surrounding environment to be in a high humidity state for a long time, affecting the working state of the staff. In order to reduce the purpose of steam diffusion, a corrugated plate 503 is provided inside the fixed frame 501. The corrugated plate 503 is corrugated and made of metal. The steam generated by spraying cooling water on the aluminum ingot mold is sucked into the fixed frame 501 and contacts the corrugated plate 503. The corrugated plate 503 condenses the steam into a liquid state to realize steam recovery. The steam generated by spraying the aluminum ingot is sucked into the fixed frame 501 through the exhaust fan 502. Since the exhaust fan 502 is provided in the fixed frame 501, the contact area with the steam is increased, so that the steam is quickly cooled and condensed, thereby reducing the working environment temperature and improving the comfort of the operators.

[0044] During specific use, the cast aluminum ingot mold is placed on the surface of the placement plate 303, and the output shaft of the motor 301 is controlled to drive the screw 302 to rotate. When the screw 302 rotates, the placement plate 303 is driven to move horizontally on its surface. The placement plate 303 drives the aluminum ingot mold to move under the shower head 207. The shower head 207 sprays coolant on the aluminum ingot mold to quickly cool it down. At the same time, since the through hole 304 is opened on the surface of the placement plate 303, its bottom is in an open state when cooling the aluminum ingot mold, which increases the contact area with the air, thereby improving the cooling speed of the aluminum liquid mold.

[0045] When the water pump 201 pumps water to spray and cool the aluminum ingot mold, water is extracted through the water inlet pipe 202. When the water passes through the water storage pipe 203, it impacts the turbine blade 404 to make it rotate. When the turbine blade 404 rotates, it drives the turntable 402 to rotate through the connecting rod. During the rotation of the turntable 402, it drives the convex column to rotate. When the convex column rotates, it drives the gear slide 403 to rotate. When the gear slide 403 rotates, it drives the rack 405 to move horizontally. When the rack 405 moves, it drives the base plate 406 to move in the horizontal direction. The impact block 408 provided at the end of the base plate 406 strikes the outer wall of the aluminum ingot mold back and forth, weakening the bonding force of the contact surface through vibration. The vibration energy can weaken the tiny welds of the metallurgical bonding, so that the adhesion parts are separated due to stress concentration, which can protect the mold and casting and improve the demoulding efficiency.

[0046] During the cooling operation, the exhaust fan 502 is used to blow air to the outside of the fixed frame 501 to accelerate the interaction between the air and the inside of the fixed frame 501. When the coolant is sprayed through the shower head 207, the air convection blows the coolant to quickly reduce the cooling temperature, thereby improving the cooling efficiency of the aluminum ingot mold. The steam generated by spraying the aluminum ingot is sucked into the inside of the fixed frame 501 through the exhaust fan 502. Since the exhaust fan 502 is provided in the fixed frame 501, the contact area with the steam is increased, so that the steam is quickly cooled and condensed, thereby reducing the working environment temperature and improving the comfort of the operators.
