Description

Technical Field

[0001] This utility model relates to the field of atomization cooling equipment technology, and in particular to an atomization water cooling equipment for aluminum alloy forgings. Background Technology

[0002] The key to cooling aluminum alloy forgings lies in balancing cooling rate and uniformity to avoid residual stress. Conventional methods are divided into three categories: air cooling is simple but has limited performance, cannot suppress second-phase coarsening and may reduce the tensile strength of the forging, and is difficult to cool the core of the forging when the forging thickness is large; liquid cooling is efficient but prone to deformation, mainly water quenching and polymer quenching. Water quenching is prone to causing cracking of the forging, while polymer quenching is expensive and requires frequent solution replacement; mist cooling is a compromise but complex to control because, under normal circumstances, mist cooling only uses a top-mounted nozzle. For example, Chinese Utility Patent No. 201910971661.1 discloses a misting cooling device used for local cooling of solar panels, which only includes a misting component set at the top, and the position and angle of the misting component are adjusted by multiple moving platforms. When using a top-mounted nozzle to complete the atomization cooling process of aluminum alloy forgings, the atomized droplets can only cool the upper surface of the forgings, making it difficult to cool the bottom surface. This results in the forgings being cold on top and hot on the bottom, or cold on the outside and hot on the inside, making it difficult to ensure uniform atomized water cooling of the aluminum alloy forgings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an atomized water cooling device for aluminum alloy forgings, which atomizes and cools all surfaces of the aluminum alloy forgings to ensure the uniformity of cooling.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an atomizing water cooling device for aluminum alloy forgings, including an atomizing chamber, a bracket provided in the atomizing chamber, a first nozzle assembly and a second nozzle assembly respectively provided on the top and side of the atomizing chamber facing the bracket, and a negative pressure assembly fixedly provided at the bottom of the atomizing chamber, with the projection of the bracket located on the negative pressure assembly.

[0005] To ensure the atomization and water cooling effect on the top and sides of the aluminum alloy forging, the first nozzle assembly further includes a plurality of high-pressure nozzles arrayed on the top of the atomization chamber, with the plurality of high-pressure nozzles facing the bracket; the second nozzle assembly includes a plurality of fan-shaped nozzles arranged in a ring around the atomization chamber, with the plurality of fan-shaped nozzles facing the side of the bracket.

[0006] To prevent droplets ejected from the fan-shaped nozzles from colliding with each other, several of the fan-shaped nozzles are further installed in the atomizing chamber with a deflection of 15° to 25°.

[0007] To ensure the downward accelerating motion of the droplets ejected from the first nozzle assembly and the second nozzle assembly, electrode rings are further provided at the output ends of both the high-pressure nozzle and the fan-shaped nozzle, and gradient electrode plates are arranged on the side wall of the atomizing chamber; within the atomizing chamber, the electric field strength gradually increases from top to bottom.

[0008] To construct a uniformly decreasing electrostatic field, the gradient electrode plate further comprises: An electrode plate array includes multiple electrode plates arranged in an array along the height direction of the atomizing chamber based on the outer edge surface of the atomizing chamber, with adjacent electrode plates separated by an insulating material; And a voltage divider resistor chain, including several high-voltage resistors of equal value and a high-voltage DC power supply, wherein several of the high-voltage resistors are connected in series with the high-voltage DC power supply, and any one of the electrode plates is connected in parallel with one or more of the high-voltage resistors.

[0009] While providing support for the aluminum alloy forging, it also provides corresponding cooling at the contact point between the aluminum alloy forging and the bracket. Furthermore, the bracket includes support rods and a support frame, with one end of each support rod connected to the inner wall of the atomizing chamber and the other end connected to the edge of the support frame. The support frame is composed of several horizontal and vertical bars, at least one of which is a hollow structure and is connected to the support frame by a circulation pipe.

[0010] In order to remove the steam generated after the droplets come into contact with the aluminum alloy forging while providing a compensating flow below the aluminum alloy forging, the negative pressure component further includes a first negative pressure zone and a second negative pressure zone. The first negative pressure zone is fixedly disposed at the bottom center of the atomizing chamber, and the second negative pressure zone is disposed based on the outer edge of the first negative pressure zone. The negative pressure intensity of the first negative pressure zone is greater than that of the second negative pressure zone.

[0011] It provides collection and aggregation for atomized droplets to facilitate their post-processing. Furthermore, it also includes a collection chamber, which is fixedly disposed at the bottom of the atomization chamber and communicates with the atomization chamber.

[0012] To monitor the liquid level in the collection chamber so that the internal liquid can be discharged in a timely manner, a liquid level sensor is further installed in the collection chamber.

[0013] To further collect moisture from the high-temperature steam, a condensation adsorption chamber is also included, with one end of the condensation adsorption chamber connected to the negative pressure component and the other end connected to the collection chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model include: 1) By applying the first nozzle assembly directly to the top surface of the aluminum alloy forging and the second nozzle assembly to the side surface of the aluminum alloy, and at the same time, setting a negative pressure assembly at the bottom of the atomizing chamber to disturb the air flow inside the atomizing chamber, thereby driving the droplets to the bottom surface of the aluminum alloy forging, the synchronous atomization cooling process of each surface of the aluminum alloy forging is completed. 2) By providing electrode rings at the output ends of the high-pressure nozzle and the fan-shaped nozzle constituting the first nozzle assembly and the second nozzle assembly, the droplets are charged after being output from the high-pressure nozzle and the fan-shaped nozzle. An electric field is set in the atomization chamber to assist the charged droplets to move along the electric field. The droplets after being controlled by the electric field have obvious directionality and a certain speed, which can accurately act on the surface of the aluminum alloy forging and break the vapor film on the surface of the aluminum alloy forging, thus ensuring the cooling effect of the aluminum alloy forging. 3) By setting up infrared monitoring equipment to monitor the surface temperature of aluminum alloy forgings, and adjusting the operation of negative pressure components and gradient electrode plates in real time based on the surface temperature data of aluminum alloy forgings, different atomization cooling methods are provided for aluminum alloy forgings with different temperature ranges, which helps to better ensure the cooling uniformity of each surface of aluminum alloy forgings.

Detailed Implementation

[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] A water-cooling device for atomizing aluminum alloy forgings, such as Figure 1 As shown, the device includes an atomizing chamber 1, which is generally spherical or cylindrical. A bracket 2 is provided within the atomizing chamber 1 to hold and support the aluminum alloy forging at the center of the chamber, facilitating the water cooling process of atomized droplets from various directions. A first nozzle assembly 3 is fixedly installed at the top of the atomizing chamber 1, and a second nozzle assembly 4 is fixedly installed on the inner side of the chamber 1. The first nozzle assembly 3 directly acts on the top side of the aluminum alloy forging, and the second nozzle assembly 4 directly acts on the side side of the forging. Based on the aforementioned first nozzle assembly 3 and second nozzle assembly 4, a negative pressure assembly 5 is fixedly installed at the bottom of the atomizing chamber 1, and the projection of the bracket 2 is located on the negative pressure assembly 5 to ensure that the negative pressure assembly 5 can act directly on the bracket 2. The negative pressure assembly 5 provides a turbulent effect in the atomizing chamber 1, so that the droplets dispersed in the atomizing chamber 1 can be guided to the side of the aluminum alloy forging facing the bracket 2 under the action of the negative pressure area, thereby completing the cooling process on that side and avoiding uneven cooling of the aluminum alloy forging.

[0019] The following combination Figure 2 and Figure 3 The first nozzle assembly 3 and the second nozzle assembly 4 are described in detail. For example... Figure 2As shown, the first nozzle assembly 3 includes a plurality of high-pressure nozzles 31 arrayed at the top of the atomizing chamber 1. These high-pressure nozzles 31 face the bracket 2 and act directly on the top region of the aluminum alloy forging. The high-pressure nozzles 31 utilize their characteristics to break the vapor film surrounding the aluminum alloy forging, ensuring effective atomization and cooling of the top region of the forging. Figure 3 As shown, the second nozzle assembly 4 includes a plurality of fan-shaped nozzles 41 arranged in a ring on the inner side of the atomizing chamber 1. The plurality of fan-shaped nozzles 41 face the side of the bracket 2. When the aluminum alloy forging is placed on the bracket 2, the fan-shaped nozzles 41 act directly on the side area of ​​the aluminum alloy forging, and at the same time can provide additional droplets for the negative pressure structure to act on the bottom surface of the aluminum alloy forging.

[0020] In conventional setups, to ensure the second nozzle assembly can cover all areas of the side of the aluminum alloy forging for atomization cooling, the fan-shaped nozzles constituting the second nozzle assembly are arranged laterally. That is, the fan-shaped nozzles need to cover a sufficient width, such as... Figure 4 As shown, it is arranged in the atomizing chamber, such as Figure 5 As shown, the atomized droplets ejected from adjacent atomizing nozzles have a significant overlapping area. Within this overlapping area, droplet collisions occur due to the influence of droplet movement direction and speed, thus affecting the atomization cooling process on the side of the aluminum alloy forging. As an improved implementation method, such as... Figure 6 As shown, the atomizing nozzle is based on Figure 4 If the nozzle is rotated by a certain angle θ (15°≤θ≤25°) as shown in the diagram, the coverage area of ​​the atomized droplets sprayed by the adjacent atomizing nozzles will be as follows: Figure 7 As shown, there is only minimal edge overlap or no overlap at all. Compared to the original implementation, the horizontal coverage area of ​​the atomized droplets ejected by a single atomizing nozzle due to rotation is significantly reduced, and by rotating the atomizing nozzle to change its coverage area, the atomized droplets ejected from the fan-shaped nozzle can itself have a certain swirling effect.

[0021] Under normal conditions, the atomized droplets ejected from the high-pressure nozzle 31 and the fan-shaped nozzle 41 are only provided with initial kinetic energy and their movement direction is controlled by the nozzles. If their movement is to be controlled subsequently, it can only be indirectly driven to move according to the internal airflow direction by disturbing the airflow direction in the atomization chamber 1. Therefore, electrode rings are provided at the output ends of the aforementioned high-pressure nozzle 31 and fan-shaped nozzle 41, and gradient electrode plates 11 are arranged on the side wall of the atomization chamber 1 to construct an electrostatic field in the atomization chamber 1.

[0022] The gradient electrode plate 11 is described in detail below. The gradient electrode plate 11 includes an electrode plate array and a voltage divider resistor chain. The aforementioned electrode plate array includes multiple electrode plates arranged along the height direction of the atomizing chamber 1 based on the outer edge of the atomizing chamber 1. Preferably, multiple annular electrode plates are arranged along the height direction of the atomizing chamber 1, with adjacent electrode plates separated by insulating material. The voltage divider resistor chain includes several equivalent precision high-voltage resistors connected in series with a high-voltage DC power supply. The number of resistors can be greater than the number of electrode plates. According to Ohm's law, the voltage drop across each resistor is equal, so the connection point between adjacent resistors is the voltage divider node. By connecting voltage divider nodes of different potentials to the arranged electrode plates, a uniformly decreasing electrostatic field can be established between the electrode plate arrays, with the field strength pointing from high potential to low potential. The uniformly decreasing electrostatic field can be constructed by outputting a negative high voltage to the voltage divider resistor chain through the high-voltage DC power supply. Furthermore, the electric field strength on a single electrode plate can be adjusted by changing the output negative high voltage.

[0023] After the gradient electrode plate 1111 is installed, the electric field strength gradually increases from top to bottom in the atomization chamber 11. For example, taking a three-layer electrode plate 1111 as an example, the potentials from top to bottom are 0kV, -4kV, and -8kV, respectively. At this time, the voltage divider resistor chain contains two high-voltage resistors of equal value. The electrode rings installed at the output ends of the high-pressure nozzle 31 and the fan-shaped nozzle 41 enable the droplets ejected from the high-pressure nozzle 31 and the fan-shaped nozzle 41 to be charged. Under the action of the electric field in the atomization chamber 11, the charged droplets will always be subjected to a vertically downward Coulomb force. As for the atomized droplets ejected from the high-pressure nozzle 31, under the action of Coulomb force, they can directly act on the top area of ​​the aluminum alloy forging at a higher speed; as for the atomized droplets ejected from the fan-shaped nozzle 41, they have a certain directionality and kinetic energy when ejected from the nozzle, and have a certain swirling effect. Then, under the action of the electric field, some of them can spirally approach and act on the side of the aluminum alloy forging while breaking through the vapor film on the surface of the aluminum alloy forging. The other part of the atomized droplets that do not act on the side of the aluminum alloy forging will move to the lower area of ​​the aluminum alloy forging under the action of the electric field. Under the action of the negative pressure component 5, the atomized droplets can be guided to continuously accumulate in this area, and under the action of negative pressure, they act as a compensating airflow on the bottom surface of the aluminum alloy forging. The vapor formed by the contact between the atomized droplets and the high-temperature aluminum alloy forging is continuously extracted by the negative pressure component 5, thereby ensuring that all surfaces of the aluminum alloy forging are subjected to atomized cooling process.

[0024] It is worth noting that during the atomization cooling process, the bracket 2 provides support for the aluminum alloy forging. There must be a contact area between the aluminum alloy forging and the bracket 2. This contact area is multiplied, and due to the contact between the aluminum alloy forging and the bracket 2, the atomized droplets are difficult to act on this area. Specifically, multiple uncooled points or contact surfaces are formed on the bottom surface of the aluminum alloy forging. To ensure the uniformity of cooling on the bottom surface of the aluminum alloy forging, such as... Figure 8 As shown, the aforementioned bracket 2 includes a support rod and a support frame 21. One end of the support rod is connected to the inner wall of the atomizing chamber 11, and the other end is connected to the edge of the support frame 21. The support frame 21 is composed of several horizontal and vertical rods, at least one of which is a hollow structure. A circulation pipe 22 is connected to the support frame 21. The circulation pipe 22 can be directly set based on the aforementioned support rod and is used to introduce refrigerant into the bracket 2 to assist the cooling process of the contact area between the aluminum alloy forging and the bracket 2.

[0025] In some implementation methods, such as Figure 9 As shown, the aforementioned negative pressure component 5 includes a first negative pressure zone 51 and a second negative pressure zone 52. The first negative pressure zone 51 is fixedly disposed at the bottom center of the atomizing chamber 11, and the second negative pressure zone 52 is disposed based on the outer edge of the first negative pressure zone 51, and the negative pressure intensity of the first negative pressure zone 51 is greater than that of the second negative pressure zone 52. It is worth noting that the difference in negative pressure intensity between the first negative pressure zone 51 and the second negative pressure zone 52 is not less than 0.5 bar. Under the suction effect of the first negative pressure zone 51, the surrounding atomized droplets and air rush into the first negative pressure zone 51 under the action of air pressure, covering the hot core area of ​​the aluminum alloy forging, quickly breaking and extracting the vapor film formed on the bottom surface of the aluminum alloy forging, clearing obstacles for the droplets to reach the surface; while the second negative pressure zone 52 located at the outer edge of the first negative pressure zone 51 has a lower negative pressure intensity than the first negative pressure zone 51, which can form a low-speed compensating flow, effectively covering all areas from the hot core area to the outermost edge of the aluminum alloy forging, generating a stable, low-speed downward or horizontal compensating airflow, which is used to "lift" and "guide" the falling charged droplets, offsetting part of the entrainment effect of the strong negative pressure of the first negative pressure zone, and gently transporting them to the edge and bottom surface of the aluminum alloy forging.

[0026] It also includes a collection chamber 6, which is fixedly installed at the bottom of the atomizing chamber 11 and connected to the atomizing chamber 11. Droplets accelerated by the electric field and droplets falling from the aluminum alloy forging can all fall into the collection chamber 6 for collection. A liquid level sensor 9 is installed in the collection chamber 6 to monitor the liquid level in real time. When the liquid level reaches a threshold range, the liquid accumulated in the collection chamber 6 is discharged, completing the processing.

[0027] In some embodiments, a condensation chamber 7 is also provided, one end of which is connected to the negative pressure component 5, and the other end is connected to the collection chamber 6. After being extracted by the negative pressure component 5, the high-temperature steam passes through the condensation chamber 7 to complete the condensation process. During this condensation process, the moisture in the high-temperature steam condenses into water droplets and flows into the collection chamber 6 to accumulate.

[0028] As a preferred embodiment, such as Figure 10 As shown, it also includes an infrared monitoring device 8, which is fixedly installed facing the bracket 2. It can be directly fixed to the inner wall of the atomizing chamber 11. It is used to monitor and acquire the surface temperature of the aluminum alloy forging in real time and transmit the surface temperature data to the control terminal 10 for judgment. The aforementioned negative pressure component 5 is controlled by the control terminal 10 to regulate the opening and closing process. The control terminal 10 can also acquire the liquid level data in the collection chamber 6.

[0029] The aforementioned negative pressure component 5 includes a Gardner Denver HBS series high-pressure centrifugal fan, a Siemens SINAMICS G120XA frequency converter, and an SMC PSE500 series vacuum pressure sensor. Two high-pressure centrifugal fans are provided, operating in the first negative pressure zone 51 and the second negative pressure zone 52 respectively. The high-pressure centrifugal fan operating in the first negative pressure zone 51 has higher power and higher air pressure, while the high-pressure centrifugal fan operating in the second negative pressure zone 52 has slightly lower power and lower air pressure. The frequency converter receives signals from the control terminal 10 and adjusts the speed of the aforementioned high-pressure centrifugal fans to precisely control the negative pressure intensity. The vacuum pressure sensor is installed on the air ducts of the first negative pressure zone 51 and the second negative pressure zone 52, providing real-time pressure feedback to the control terminal 10, forming a closed-loop control.

[0030] The aforementioned infrared monitoring device 8 can be a FLIR A8582 mid-wave IR (MWIR) thermal imager, which can cover 0-2000℃ and meet the requirements of the entire cooling process of aluminum alloy forgings; the control terminal 10 includes an industrial computer and a Beckhoff AX8000 series real-time motion controller. The industrial computer receives temperature field images from the infrared monitoring device 8 and determines the surface temperature of the aluminum alloy forgings. The I / O module integrated in the industrial computer obtains the liquid level data in the collection chamber 6. The real-time motion controller is used to control the frequency converter in the negative pressure component and the high-voltage DC power supply used to power the gradient electrode plate 11. The real-time motion controller can also complete the discharge process of the liquid accumulated in the collection chamber 6 and adjust the negative high voltage intensity output by the high-voltage DC power supply in the gradient electrode plate 11.

[0031] In a preferred embodiment, during actual use, when the surface temperature of the aluminum alloy forging is greater than 350°C, the negative pressure intensity of the first negative pressure zone 51 in the negative pressure assembly 5 is 0.6 bar, the negative pressure intensity of the second negative pressure zone 52 is 0.1 bar, and the maximum electric field intensity of the gradient electrode plate 1111 is set to 8 kV; when the surface temperature of the aluminum alloy forging is between 250°C and 350°C, the negative pressure intensity of the first negative pressure zone 51 in the negative pressure assembly 5 is adjusted to 0.7 bar, the negative pressure intensity of the second negative pressure zone 52 is adjusted to 0.2 bar, and the negative pressure assembly 5 is adjusted to pulse mode, specifically alternating opening and closing, with an opening time of 4 seconds and a closing time of 2 seconds, and the maximum electric field intensity of the gradient electrode plate 1111 is set to 4 kV; when the surface temperature of the aluminum alloy forging is less than 250°C, the negative pressure assembly 5 is closed while the maximum electric field intensity of the gradient electrode plate 11 is set to 0 kV to prevent the aluminum alloy forging from overcooling.

[0032] The aluminum alloy forgings are cooled using the atomized water cooling equipment of this invention. Taking 7075 aluminum alloy forgings as an example, the cooling effect compared to traditional mist cooling methods is shown in the table below:

[0033] Metallographic analysis revealed a grain size distribution of 12.5 ± 1.8 μm (compared to 15.3 ± 6.2 μm in the traditional scheme) and a residual stress range of ≤ 45 MPa (compared to > 180 MPa in the traditional scheme).

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
