Description

Technical Field

[0001] This application relates to the field of aluminum ingot cooling technology, and in particular to a cooling device for aluminum ingot forming. Background Technology

[0002] Aluminum ingots are an industrial raw material, also known as remelted aluminum ingots according to national standards. They are produced by electrolysis of alumina-cryolite or obtained by remelting recycled aluminum products. Due to its excellent physical properties, aluminum is widely used in aerospace, automotive, and aircraft industries.

[0003] After recycling, waste aluminum products need to be remelted and poured into molds to obtain remelted aluminum ingots, which are then sent back to various aluminum product manufacturing companies. The remelted aluminum ingots need to be cooled before they can be stored. Typically, this cooling method uses immersion cooling, where the ingots are directly placed in a water tank to cool them. However, this method requires manual removal of the ingots and is extremely wasteful of water resources. Utility Model Content

[0004] To facilitate the cooling of aluminum ingots without the need for manual retrieval and to save water resources, this application provides a cooling device for aluminum ingot forming.

[0005] The cooling device for aluminum ingot forming provided in this application adopts the following technical solution: A cooling device for aluminum ingot forming includes a chamber, a water tank, and a conveying mechanism for conveying aluminum ingots. The chamber has material inlets penetrating the inside and outside of the chamber on opposite side walls. The conveying mechanism enters the chamber through one of the material inlets and exits the chamber through the other material inlet. An atomizer and a first blower are installed at the top of the chamber. A water pump is installed in the water tank and is connected to the atomizer.

[0006] By adopting the above technical solution, the aluminum ingots are transported through a conveying mechanism connected to the aluminum ingot production line. During the transport process, the aluminum ingots pass through the silo, where a water pump delivers water or cooling liquid from the water tank to an atomizer. The atomizer converts the water or cooling liquid into water mist, and a first blower blows the water mist onto the aluminum ingots on the conveying mechanism. The water mist comes into contact with the high-temperature aluminum ingot surface, rapidly vaporizes, and absorbs heat to cool the aluminum ingots. Moreover, under the action of the first blower, the water mist vaporizes faster and absorbs heat at a higher rate. Compared with the traditional immersion cooling method, it does not require a large amount of water to come into contact with the aluminum ingots, reducing water consumption. Furthermore, it eliminates the need for manual handling or retrieval of aluminum ingots, reducing labor intensity.

[0007] Preferably, a collector is fixedly installed at the bottom of the chamber, and a discharge pipe is connected to the bottom of the collector. A second blower is installed on the discharge pipe to guide the gas inside the chamber and discharge it through the discharge pipe.

[0008] By adopting the above technical solution, the collector receives the water mist particles that are not fully vaporized in the chamber and guides the vaporized water vapor toward the exhaust pipe, thus preventing the liquid from accumulating at the bottom of the chamber. At the same time, the second blower guides the hot and humid gas (water vapor after water mist vaporization and hot air generated by the cooling of aluminum ingots) in the chamber to be discharged outward along the exhaust pipe, thereby accelerating the air circulation rate in the chamber and alleviating the hot and humid environment inside the chamber.

[0009] Preferably, a condenser is provided on the discharge pipe, and the discharge pipe is connected to the water tank.

[0010] By adopting the above technical solution, when the hot and humid gas in the chamber is guided into the discharge pipe by the second blower, the condenser cools and liquefies the water vapor in the gas, turning the water vapor into liquid water. The liquefied water and the atomized water droplets flow back to the water tank through the discharge pipe, realizing the recycling of water resources, reducing the frequency of water tank replenishment, and further improving the effect of water conservation.

[0011] Preferably, the feed inlet is provided with a rubber curtain for blocking the feed inlet.

[0012] By adopting the above technical solution, the rubber curtain forms a flexible barrier to the material inlet. When the aluminum ingot passes through, it naturally pushes open the rubber curtain. After passing through, the rubber curtain can automatically reset and close. This not only does not hinder the conveying mechanism from driving the aluminum ingot into and out of the silo, but also reduces the amount of water mist in the silo from overflowing out of the material inlet, thus reducing the amount of water mist loss and reducing water waste.

[0013] Preferably, the conveying mechanism includes a machine body, belt rollers, a synchronous belt, and a drive motor. Several belt rollers are rotatably arranged on the machine body, and all belt rollers are connected by a synchronous belt drive. The synchronous belt is used to carry aluminum ingots. The drive motor is fixedly connected to the machine body, and the output end of the drive motor is coaxially fixed with any of the belt rollers.

[0014] By adopting the above technical solution, the drive motor drives the belt rollers fixed to it to rotate. Since all the belt rollers are connected by synchronous belt transmission, the rotation of a single belt roller can drive the other belt rollers to rotate synchronously, thereby making the synchronous belt circulate along the machine body to complete the conveying of aluminum ingots. As the load-bearing component of aluminum ingots, the synchronous belt is supported by multiple belt rollers, which helps to prevent the synchronous belt from sinking due to local weight when carrying aluminum ingots.

[0015] Preferably, the machine body is fixedly provided with a fixing frame on both sides, the fixing frame is located outside the chamber body, a first wiping wheel is rotatably provided on the fixing frame, a first water-absorbing sponge is sleeved on the peripheral wall of the first wiping wheel, the first water-absorbing sponge can contact the side wall of the aluminum ingot, and the fixing frame is also provided with a drive mechanism for driving the first wiping wheel to rotate.

[0016] By adopting the above technical solution, after the aluminum ingot is sent out from the feed port of the silo by the conveying mechanism, it passes through the first wiping wheel at the fixed frame on both sides of the machine body; the first water-absorbing sponge on the periphery of the first wiping wheel contacts the side wall of the aluminum ingot, absorbing the water mist remaining on the side wall of the aluminum ingot due to atomization and cooling, reducing the subsequent drying time and drying difficulty; and the driving mechanism drives the first wiping wheel to rotate, which on the one hand reduces the relative friction between the first water-absorbing sponge and the side wall of the aluminum ingot, and on the other hand, continuously changes the part of the first water-absorbing sponge that contacts the aluminum ingot, so that the first water-absorbing sponge can hold more water, reducing the frequency of cleaning or replacing the first water-absorbing sponge.

[0017] Preferably, the driving mechanism includes a first bevel gear, a second bevel gear, a driving pulley, a driven pulley, and a transmission belt. The first bevel gear is coaxially fixed with a belt roller, the second bevel gear is rotatably connected to a fixed frame, the first bevel gear and the second bevel gear mesh with each other, the driving pulley is coaxially fixed with the second bevel gear, the driven pulley is coaxially fixed with the first wiping wheel, and the driving pulley and the driven pulley are connected by a transmission belt.

[0018] By adopting the above technical solution, when the belt roller rotates, it drives the first bevel gear to rotate synchronously. The first bevel gear meshes with the second bevel gear, which in turn drives the drive pulley, which is coaxial with the second bevel gear, to rotate. The drive pulley transmits power to the driven pulley through the transmission belt, which ultimately drives the first wiping wheel to rotate. In this way, the first wiping wheel can be driven without the need for additional power components such as motors, thereby reducing the manufacturing and maintenance costs and energy consumption of the equipment.

[0019] Preferably, a suspension is fixedly installed on the body, the suspension is located outside the chamber, a second wiping wheel is rotatably installed on the suspension, a second water-absorbing sponge is sleeved on the peripheral wall of the second wiping wheel, the second water-absorbing sponge can contact the top wall of the aluminum ingot, a torsion motor is fixedly installed on the suspension, and the drive shaft of the torsion motor is coaxially fixed with the second wiping wheel.

[0020] By adopting the above technical solution, after the aluminum ingot is sent out of the material port of the silo by the conveying mechanism, it passes through the second wiping wheel. The second water-absorbing sponge on the periphery of the second wiping wheel contacts the top wall of the aluminum ingot, absorbing the water mist remaining on the top wall of the aluminum ingot due to atomization and cooling, reducing the subsequent drying time and drying difficulty. In addition, the driving mechanism drives the second wiping wheel to rotate, which on the one hand reduces the relative friction between the second water-absorbing sponge and the side wall of the aluminum ingot, and on the other hand, continuously changes the part of the second water-absorbing sponge that contacts the aluminum ingot, so that the second water-absorbing sponge can hold more water, reducing the frequency of cleaning or replacing the second water-absorbing sponge.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a silo, water tank, conveying mechanism, material inlet, atomizer, and first blower, the aluminum ingot is automatically cooled during the conveying process. There is no need for manual handling or retrieval of aluminum ingots, which reduces labor intensity. The atomized water mist comes into contact with the high-temperature aluminum ingot and quickly vaporizes and absorbs heat. Combined with the first blower to accelerate vaporization, the cooling efficiency is improved. Compared with traditional immersion cooling, water consumption is reduced. 2. By setting up a collector, a discharge pipe, a second blower, and a condenser, the collector collects the incompletely vaporized water mist particles, the second blower accelerates the discharge of hot and humid gas in the chamber, avoiding the hot and humid environment in the chamber from affecting the cooling effect, and the condenser liquefies the water vapor in the hot and humid gas, so that the water flows back to the water tank for recycling, further reducing water waste and reducing the frequency of water tank replenishment. 3. By setting up a machine body, belt roller, synchronous belt, drive motor, fixed frame, first wiping wheel, first water-absorbing sponge, first bevel gear, second bevel gear, driving pulley, driven pulley, and transmission belt, the first water-absorbing sponge of the first wiping wheel absorbs the water mist remaining on the side wall of the aluminum ingot, reducing the difficulty and time of subsequent drying treatment. Moreover, the drive mechanism drives the first wiping wheel to rotate with the power of the belt roller, eliminating the need for an additional power source and saving energy and equipment costs.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a cooling device for aluminum ingot forming. (Refer to...) Figure 1 It includes a storage tank 1, a water tank 2, and a conveying mechanism 3 for conveying aluminum ingots. The storage tank 1 has a material inlet 11 on each of its opposite side walls along its length, which penetrates the inside and outside of the storage tank 1. A rubber curtain 111 is provided on the material inlet 11 to cover the material inlet 11. The conveying mechanism 3 enters the storage tank 1 through one material inlet 11 and exits the storage tank 1 through the other material inlet 11. When the aluminum ingot passes through the material inlet 11, it pushes open the rubber curtain 111, and then the rubber curtain 111 can close again under the action of gravity.

[0028] Reference Figure 1 and Figure 2 Several atomizers 12 and a first blower 13 are fixedly installed at the top of the chamber 1. The first blower 13 penetrates the top wall of the chamber 1 and supplies air from outside the chamber 1 into the chamber 1. A water pump is installed in the water tank 2, and the water pump is connected to the atomizers 12 through a pipe. The atomizers 12 atomize the water or coolant supplied by the water pump into water mist. The first blower 13 blows the water mist toward the aluminum ingots on the conveying mechanism 3. The water mist comes into contact with the hot surface of the aluminum ingots, rapidly vaporizes and absorbs heat to cool the aluminum ingots. Moreover, under the action of the airflow from the first blower 13, the water mist vaporizes faster and absorbs heat at a higher rate.

[0029] Reference Figure 1 and Figure 2 A collector 14 is fixedly installed at the bottom of the chamber 1. The collector 14 is a funnel with a flared top. The top sidewall of the collector 14 is attached to and fixed to the inner sidewall of the chamber 1. The bottom of the collector 14 penetrates the bottom wall of the chamber 1 and is connected to a discharge pipe 15. A second blower 151 is installed on the discharge pipe 15 to guide the gas in the chamber 1 and discharge it through the discharge pipe 15. A condenser 152 is also installed at the end of the discharge pipe 15, and the end of the discharge pipe 15 is connected to a water tank 2. In this embodiment, the second blower 151 is fixedly connected to the chamber 1, the middle part of the discharge pipe 15 is connected to the bottom of the collector 14, one end of the discharge pipe 15 is fixedly connected to the second blower 151, and the condenser 152 is installed at the other end of the discharge pipe 15. The second blower 151 blows air into the discharge pipe 15, and the other end of the discharge pipe 15 finally extends into the water tank 2. The condenser 152 can be a blade-type condenser 152.

[0030] Reference Figure 1 and Figure 2 Collector 14 receives incompletely vaporized water mist particles in chamber 1 and guides vaporized water vapor toward the exhaust pipe. Second blower 151 blows air into exhaust pipe 15, using atmospheric pressure to make collector 14 absorb water mist in chamber 1, and drive the water, water mist and water vapor collected by collector 14 to flow toward condenser 152. Water tank 2 at the end of exhaust pipe collects the re-condensed water.

[0031] Reference Figure 1 and Figure 2 The conveying mechanism 3 includes a body 31, belt rollers 32, a synchronous belt 33, and a drive motor 34. The body 31 is fixedly connected to the two side walls of the feed inlet 11, and the body 31 is parallel to the length direction of the hopper 1. Several belt rollers 32 are evenly and spaced along the length direction of the body 31. The belt rollers 32 are rotatably connected to the body 31 via bearings, and the axis of the belt rollers is parallel to the width direction of the body 31. All belt rollers 32 are connected by the synchronous belt 33 for transmission, and the belt rollers 32 and the synchronous belt 33 mesh for transmission. The synchronous belt 33 is used to carry aluminum ingots. The drive motor 34 is fixedly connected to the body 31, and the output end of the drive motor 34 is coaxially fixed with any one of the belt rollers 32.

[0032] To facilitate the removal of residual water mist from aluminum ingots due to atomization and cooling, and to reduce subsequent drying time and difficulty, refer to... Figure 3 The machine body 31 has two fixed brackets 4 fixed symmetrically on both sides in the width direction. A suspension 5 is also fixedly installed on the machine body 31. The suspension 5 and the two fixed brackets 4 are all located outside the chamber 1, specifically on the side where the aluminum ingot detaches from the chamber 1. A second wiping wheel 51 is rotatably mounted on the suspension 5. The axis of the second wiping wheel 51 is parallel to the width direction of the machine body 31. A second absorbent sponge 52 is sleeved on the peripheral wall of the second wiping wheel 51, and the second absorbent sponge 52 can contact the top wall of the aluminum ingot. A torsion motor 53 is fixedly installed on the suspension 5, and the drive shaft of the torsion motor 53 is coaxially fixed with the second wiping wheel 51.

[0033] Reference Figure 3 A first wiping wheel 41 is rotatably mounted on the fixed frame 4, and the axis of the first wiping wheel 41 is parallel to the height direction of the machine body 31. A first absorbent sponge 42 is sleeved on the peripheral wall of the first wiping wheel 41, and the first absorbent sponge 42 can contact the side wall of the aluminum ingot.

[0034] Reference Figure 3 The fixed frame 4 is also equipped with a drive mechanism 43 for driving the first wiping wheel 41 to rotate. Specifically, the drive mechanism 43 includes a first bevel gear 431, a second bevel gear 432, a driving pulley 433, a driven pulley 434, and a transmission belt 435. The first bevel gear 431 is coaxially fixed to a roller 32, and the second bevel gear 432 is rotatably connected to the fixed frame 4, with its axis parallel to the height direction of the frame. The first bevel gear 431 and the second bevel gear 432 mesh with each other. The driving pulley 433 is coaxially fixed to the second bevel gear 432, and the driven pulley 434 is coaxially fixed to the first wiping wheel 41. The driving pulley 433 and the driven pulley 434 are connected by a transmission belt 435, with one end of the transmission belt 435 sleeved on the driving pulley 433 and the other end sleeved on the driven pulley 434.

[0035] Reference Figure 3When the roller 32 rotates, it drives the first bevel gear 431 to rotate synchronously. The first bevel gear 431 meshes with the second bevel gear 432, which in turn drives the drive pulley 433 to rotate. The drive pulley 433 drives the driven pulley 434 to rotate through the transmission belt 435, ultimately driving the first wiping wheel 41 to rotate. The torsion motor 53 directly drives the second wiping wheel 51 to rotate. This achieves the following: when the aluminum ingot is sent out of the feed port 11 of the hopper 1 by the conveying mechanism 3, the first absorbent sponge 42 contacts the side wall of the aluminum ingot, and the second absorbent sponge 52 contacts the top wall of the aluminum ingot, absorbing the water mist remaining in the aluminum ingot due to atomization and cooling, reducing the subsequent drying time and drying difficulty. Furthermore, the rotation of the first wiping wheel 41 and the second wiping wheel 51 reduces the relative friction between the first absorbent sponge 42, the second absorbent sponge 52 and the aluminum ingot, and also continuously changes the part of the first absorbent sponge 42 and the second absorbent sponge 52 that comes into contact with the aluminum ingot, so that the first absorbent sponge 42 and the second absorbent sponge 52 can hold more water, thus reducing the frequency of cleaning or replacement of the first absorbent sponge 42 and the second absorbent sponge 52.

[0036] The implementation principle of the cooling device for aluminum ingot forming in this embodiment is as follows: The conveying mechanism 3 conveys the aluminum ingot, allowing it to pass through the chamber 1 during the conveying process. A water pump delivers water or cooling liquid from the water tank 2 to the atomizer 12, which converts the water or cooling liquid into water mist. A first blower 13 blows the water mist onto the aluminum ingot on the conveying mechanism 3. The water mist contacts the surface of the high-temperature aluminum ingot, rapidly vaporizes, and absorbs heat to cool the ingot. Furthermore, under the action of the first blower 13, the water mist vaporizes faster and absorbs heat at a higher rate. Compared to the traditional immersion cooling method, this method eliminates the need for a large amount of water to contact the aluminum ingot, reducing water consumption. Additionally, it eliminates the need for manual handling or retrieval of the aluminum ingot, reducing labor intensity.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
