[0002] As a lightweight porous material, aluminum foam has a wide range of applications in the fields of construction, transportation, aerospace, etc. During its production process, it needs to go through a high-temperature foaming stage, and then needs to be rapidly cooled to stabilize the cell structure and ensure the material properties. However, the traditional cooling methods for aluminum foam have the following deficiencies: Natural cooling or conventional air cooling has low efficiency, and uneven cooling easily leads to cell collapse or deformation, affecting the mechanical properties and appearance quality of the product; Most existing forced air cooling systems use single-direction air supply, with uneven air flow distribution and difficult to accurately control. Especially when dealing with large-sized or complex-shaped aluminum foam, the cooling effect is poor; After the cooling system operates for a long time, the air supply components (such as ventilation holes) are easily blocked by aluminum powder or process residues, and cleaning and maintenance require shutdown and disassembly, seriously affecting production efficiency.

The air compressor outputs air flow, and the air flow is transported by the dryer to the inside of the vortex tube. The air flow passing through the vortex tube is divided into a hot air flow and a cold air flow, and the cold air flow is transported through a pipeline connected between the vortex tube and the flow dividing seat; Two rotating holes are provided on the side wall of the flow dividing seat. Two blowing rollers are arranged side by side and in parallel. An interval space for transporting aluminum foam materials is formed between the two blowing rollers. One end of the blowing roller is rotatably connected to the rotating hole, and the other end of the blowing roller is rotatably connected to the output end of the first motor. The first motor drives the blowing roller to rotate; The blowing roller is connected and communicated with the flow dividing seat. Ventilation holes are provided on the outer wall of the blowing roller. The cold air flow enters the flow dividing seat through the pipeline connected between the vortex tube and the flow dividing seat and is transported outward from the ventilation holes through the inside of the blowing roller; The flow deflector is rotatably arranged inside the flow dividing seat. The second motor is connected to the flow deflector, and the second motor drives the flow deflector to rotate inside the flow dividing seat. The rotational connection between the flow deflector and the flow dividing seat is located between the two rotation holes.

[0005] Further, the controller is respectively connected to the air compressor, the first motor, and the second motor, and the controller is configured as follows: In the cooling mode, drive the second motor to drive the flow deflector to rotate to a horizontal position and be parallel to the two air supply rollers, drive the two first motors to rotate at the same speed and in opposite directions, and drive the air compressor to operate at a first power; In the cleaning mode, drive the second motor to drive the flow deflector to rotate inside the flow dividing seat, drive the air compressor to operate at a second power, drive the two first motors to rotate at different speeds and in opposite directions, and the second power is greater than the first power.

[0006] Further, the flow dividing seat includes a conveying cavity and a diffusing cavity. The rotation holes are provided on the side wall of the diffusing cavity. The outer contour of the diffusing cavity expands outward along the side facing the rotation holes, and the flow deflector is located inside the diffusing cavity.

[0007] Further, in the cooling mode, the flow deflector is perpendicular to the side wall of the diffusing cavity provided with the rotation holes.

[0008] Further, the connection between the diffusing cavity and the conveying cavity is the limit position of the rotation of the flow deflector inside the diffusing cavity.

[0009] Further, in the cleaning mode, the ratio of the rotational speeds of the two first motors is 2.

[0010] Further, the diffusing cavity is hemispherical, and the side wall of the diffusing cavity provided with the rotation holes is arranged in the vertical direction.

[0012] Further, the flow deflector is a straight plate, and the rotational connection between the flow deflector and the flow dividing seat is located at the midpoint of the center line connecting the centers of the two rotation holes.

[0013] The embodiments of the present application have the following beneficial effects: The cooling system uses an air compressor, a dryer, and a vortex tube to work together to separate compressed air into hot air flow and cold air flow. The cold air flow is accurately delivered to the air supply roller through a shunt base to achieve directional cooling. The shunt base includes a combined structure of a conveying cavity and a hemispherical diffuser cavity, and is equipped with a rotatable straight plate deflector. The angle of the deflector is controlled by a second motor. In the cooling mode, the deflector is horizontally parallel to the air supply roller to ensure that the cold air flow is evenly distributed to the ventilation holes of the two air supply rollers, forming a stable air flow covering the surface of the aluminum foam material. The air supply roller is driven by a first motor to rotate in the reverse direction, which not only promotes material transportation but also enhances air flow disturbance, improving the heat transfer efficiency. The multi-mode management of the controller further strengthens the system function: In the cooling mode, the air compressor operates at a lower power, and the motors are synchronously controlled to rotate in the same speed and opposite directions, taking into account both energy consumption and cooling uniformity; in the cleaning mode, the compressor power is increased, and the air supply roller is driven to rotate in the reverse direction with a 2:1 speed difference.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0017] To further illustrate the technical solutions provided by the embodiments of the present application, the following will provide a detailed description in conjunction with the accompanying drawings and specific implementation manners. Although the embodiments of the present application provide method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or non-creative labor. In steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiments of the present application.

[0018] Refer to Figures 1-4 As shown, the present application provides a cooling system for the production and preparation of aluminum foam, which includes an air compressor 11, a dryer 12, a vortex tube 13, a flow dividing seat 20, a guide plate 30, a blowing roller 40, a first motor 51, a second motor 52, and a controller 60.

[0019] The air compressor 11 is connected to the dryer 12, and the dryer 12 is connected to the vortex tube 13. The air compressor 11 outputs air flow, and the air flow is transported to the inside of the vortex tube 13 through the dryer 12. The air flow passing through the vortex tube 13 is divided into a hot air flow and a cold air flow, and the cold air flow is transported through the pipeline connected between the vortex tube 13 and the flow dividing seat 20.

[0020] The air compressor 11 serves as the power source of the cooling system, used to generate high-pressure air flow, providing a basic air source for the subsequent cooling process. Its output end is connected to the dryer 12 to ensure that the air entering the system has sufficient pressure and flow rate to meet the cooling requirements.

[0021] The dryer 12 is connected between the air compressor 11 and the vortex tube 13, used to dehumidify the compressed air and remove moisture and impurities therein. The dried air can avoid affecting the air flow stability due to water vapor condensation in the subsequent cooling process, and at the same time reduce the risk of corrosion or blockage of the vortex tube 13 and the air supply system, improving the reliability of the system operation.

[0022] The vortex tube 13, as the core refrigeration component, receives the compressed air from the dryer 12 and uses the vortex effect to separate the air flow into a high-temperature air flow and a low-temperature air flow. Among them, the cold air flow is transported to the flow dividing seat 20 through the pipeline, and then enters the blowing roller 40, and finally efficiently cools the aluminum foam material through the ventilation holes 41; the hot air flow can be discharged or recycled through appropriate means.

[0023] The application of the vortex tube 13 enables the system to achieve a stable supply of low-temperature air flow without additional refrigerants, simplifies the structure of the cooling system, and improves the energy efficiency ratio at the same time.

[0024] Two rotating holes 23 are provided on the side wall of the flow dividing seat 20. Two air supply rollers 40 are arranged side by side and parallel to each other. An interval space for conveying the aluminum foam material is formed between the two air supply rollers 40. One end of the air supply roller 40 is rotatably connected to the rotating hole 23, and the other end of the air supply roller 40 is rotatably connected to the output end of the first motor 51. The air supply roller 40 is driven to rotate by the first motor 51.

[0025] The air supply roller 40 is communicatively connected with the flow dividing seat 20. Ventilation holes 41 are provided on the outer wall of the air supply roller 40. A plurality of ventilation holes 41 are arranged around the outer wall of the air supply roller 40. The cold air flows through the pipeline connected between the vortex tube 13 and the flow dividing seat 20 and enters the flow dividing seat 20, and is then conveyed outward from the inside of the air supply roller 40 through the ventilation holes 41.

[0026] The air supply roller 40 is communicatively connected with the flow dividing seat 20, and a transmission channel for cold air is formed inside it. A plurality of ventilation holes 41 arranged around the outer wall are communicated with the diffusion chamber 22 inside the flow dividing seat 20. When the cold air flows through the vortex tube 13 and the flow dividing seat 20 and is conveyed to the inside of the air supply roller 40, it can be evenly ejected to the outside through the ventilation holes 41.

[0027] Two air supply rollers 40 are arranged side by side and parallel to each other, and an interval space for conveying the aluminum foam material is formed between them. The ejected cold air directly acts on the upper and lower surfaces or both sides of the material, forming a symmetrical cooling air flow field. This structural design enables the cold air to contact the material in a planar covering manner, ensuring the uniformity and efficiency of the cooling process and avoiding problems such as insufficient local cooling or overcooling.

[0028] One end of the air supply roller 40 is rotatably connected to the side wall of the diffusion chamber 22 of the flow dividing seat 20 through the rotating hole 23, and the other end is fixedly connected to the output end of the first motor 51, forming a stable mechanical support structure. This connection method not only ensures the coaxiality and stability of the air supply roller 40 during high-speed rotation, but also realizes the switching of the motion state in the cooling mode and the cleaning mode through the controllability of the rotation speed of the first motor 51.

[0029] In the cooling mode, the two first motors 51 rotate in opposite directions at the same speed, so that the air supply rollers 40 maintain synchronous movement, ensuring the stability of the cold air output direction; in the cleaning mode, the differential rotation strengthens the cleaning function through the mechanical motion characteristics.

[0030] The air supply roller 40 forms an air flow transmission link with the vortex tube 13, the dryer 12, and the air compressor 11 through the flow dividing seat 20. The high-pressure air provided by the air compressor 11 is dried and vortex separated, and then distributed to the air supply roller 40 through the diffusion chamber 22 of the flow dividing seat 20. The controller 60 realizes the function switching of the air supply roller 40 in the cooling and cleaning modes by adjusting the rotation speed of the first motor 51, the angle of the deflector 30 driven by the second motor 52, and the power of the air compressor 11.

[0031] The flow splitting seat 20 includes a conveying cavity 21 and a flow expanding cavity 22. A rotating hole 23 is arranged on the side wall of the flow expanding cavity 22. The outer contour of the flow expanding cavity 22 is arranged to expand outward along the side facing the rotating hole 23. The flow expanding cavity 22 is hemispherical, and the side wall of the flow expanding cavity 22 where the rotating hole 23 is arranged is arranged in the vertical direction.

[0032] The flow splitting seat 20 is connected to the vortex tube 13 through a pipeline, receives the cold air flow after drying treatment, and realizes the switching between the cooling and cleaning modes under the command of the controller 60 through the mechanical linkage of the air supply roller 40 with the first motor 51 and the flow guiding plate 30 with the second motor 52. Its structural design forms a complete cooling link with the air source supply of the air compressor 11 and the air flow separation function of the vortex tube 13, jointly ensuring the stability and efficiency of the cooling process in the production and preparation of aluminum foam.

[0033] The flow splitting seat 20 includes a conveying cavity 21 and a flow expanding cavity 22 that are interconnected. Among them, the flow expanding cavity 22 is designed to expand outward in a hemispherical shape, and its outer contour gradually expands along the side facing the rotating hole 23. When the cold air flow enters the flow expanding cavity 22 from the vortex tube 13 through the conveying cavity 21, the gradual expansion of the cavity volume can reasonably reduce the air flow speed, avoiding the impact of the high-speed air flow on the subsequent air supply roller 40 and the aluminum foam material.

[0034] At the same time, the hemispherical curved surface structure guides the uniform diffusion of the air flow, enabling the cold air flow to form a stable flow field distribution in the flow expanding cavity 22, laying a foundation for the uniform output of the cold air flow through the air supply roller 40 subsequently.

[0035] Two rotating holes 23 are arranged on the side wall of the flow expanding cavity 22. Two air supply rollers 40 are installed side by side and parallel in the rotating holes 23, and are rotationally connected through the rotating holes 23 at one end and connected to the output end of the first motor 51 at the other end. The arrangement of the rotating holes 23 provides a stable mechanical support for the air supply rollers 40, ensuring that the air supply rollers 40 can rotate uniformly around the axis under the drive of the first motor 51.

[0036] Ventilation holes 41 are arranged around the outer wall of the air supply roller 40 and are communicated with the inside of the flow splitting seat 20, enabling the cold air flow in the flow expanding cavity 22 to be evenly ejected from the ventilation holes 41 through the inside of the air supply roller 40 and directly act on the surface of the aluminum foam material, realizing efficient cooling.

[0037] Inside the flow dividing seat 20, a flow guiding plate 30 is rotatably arranged, and its rotation axis is located at the midpoint of the connection line of the centers of the two rotation holes 23. In the cooling mode, the flow guiding plate 30 rotates to the horizontal position, parallel to the two air supply rollers 40 and perpendicular to the side wall of the flow expanding cavity 22, dividing the cold air flow into two equal parts and respectively guiding them into the two air supply rollers 40 to ensure uniform cooling of both sides of the aluminum foam material; in the cleaning mode, the flow guiding plate 30 can be driven by the second motor 52 to rotate, changing the distribution ratio of the air flow between the two air supply rollers 40, and cooperating with the air compressor 11 to work at a higher power and the two air supply rollers 40 to rotate at different speeds to achieve the function of flushing and cleaning the ventilation holes 41 of the air supply rollers 40 and the surface of the aluminum foam material with the air flow.

[0038] The flow guiding plate 30 is located inside the flow expanding cavity 22, and the connection between the flow expanding cavity 22 and the conveying cavity 21 is the limit position of the rotation of the flow guiding plate 30 inside the flow expanding cavity 22.

[0039] A flow guiding plate 30 is rotatably arranged inside the flow dividing seat 20. The second motor 52 is connected to the flow guiding plate 30, and the second motor 52 drives the flow guiding plate 30 to rotate inside the flow dividing seat 20. The rotation connection between the flow guiding plate 30 and the flow dividing seat 20 is located between the two rotation holes 23. The flow guiding plate 30 is a straight plate, and the rotation connection between the flow guiding plate 30 and the flow dividing seat 20 is located at the midpoint of the connection line of the centers of the two rotation holes 23.

[0040] The flow guiding plate 30 adopts a straight plate structure, and its rotation axis is located at the midpoint of the connection line of the centers of the two rotation holes 23. This arrangement enables the flow guiding plate 30 to equally divide the cold air flow into the two air supply rollers 40 in the horizontal state, and it can adjust the air flow distribution ratio between the two air supply rollers 40 in the rotating state. The flow guiding plate 30 is driven by the second motor 52 to rotate, and its angle change directly affects the distribution state of the air flow between the air supply rollers 40.

[0041] The flow guiding plate 30 adopts a straight plate structure, and its rotation axis is located at the midpoint of the connection line of the centers of the two rotation holes 23. This geometric layout ensures the symmetric adjustment ability of the flow guiding plate 30 for the two air flows during rotation. By changing the included angle between the flow guiding plate 30 and the air flow direction, the cross-sectional area of the air flow channel inside the flow expanding cavity 22 can be changed in real time, thereby precisely controlling the air flow rate distributed to each air supply roller 40.

[0042] This adjustment process does not require additional valves or complex control components and can be achieved only through mechanical rotation, simplifying the system structure and improving the adjustment response speed and reliability.

[0043] The controller 60 is respectively connected to the air compressor 11, the first motor 51, and the second motor 52. The deflector 30 is electrically connected to the controller 60 through the second motor 52 and receives the mode switching instruction from the controller 60. In the cooling mode, it works in coordination with the first power output of the air compressor 11 and the same-speed reverse rotation of the air supply rollers 40 to form a stable and uniform cooling system; in the cleaning mode, it cooperates with the second power output of the air compressor 11 and the differential rotation of the air supply rollers 40 to construct a dynamic air flow cleaning system. The setting of the deflector 30 upgrades the flow splitting seat 20 from a single air flow distribution device to an intelligent adjustment unit with mode switching ability, further improving the process adaptability and functionality of the cooling system in the production of aluminum foam.

[0044] The controller 60 is configured to: in the cooling mode, drive the second motor 52 to drive the deflector 30 to rotate to a horizontal position and be parallel to the two air supply rollers 40. In the cooling mode, the deflector 30 is perpendicular to the side wall of the flow expansion chamber 22 provided with the rotation holes 23, drive the two first motors 51 to rotate at the same speed and in opposite directions, and drive the air compressor 11 to work at the first power.

[0045] In the cooling mode, the deflector 30 is driven by the second motor 52 to rotate to the horizontal position. At this time, the deflector 30 is parallel to the two air supply rollers 40 and perpendicular to the side wall of the flow expansion chamber 22 provided with the rotation holes 23. This position enables the deflector 30 to evenly divide the cold air flow in the flow expansion chamber 22 into two independent air paths, upper and lower, and respectively introduce them into the two air supply rollers 40.

[0046] When the cold air flow is ejected from the ventilation holes 41 on the outer wall of the air supply roller 40, it can form a symmetric and uniform cooling air flow coverage on both sides of the aluminum foam material, ensuring that the material obtains a consistent cooling effect during transportation and avoiding problems such as cooling efficiency differences or local overheating caused by uneven air flow distribution.

[0047] Specifically, the two air supply rollers 40 are arranged side by side and parallel, and the rotation method of opposite directions and the same speed makes the linear speeds on their surfaces equal in magnitude and opposite in direction. Since the ventilation holes 41 on the outer wall of the air supply roller 40 are arranged in a circular pattern, when the cold air flow passes through the ventilation holes 41 and is ejected, the air supply rollers 40 rotating in opposite directions form symmetric air flow ejection trajectories on both sides of the material.

[0048] The deflector 30 is in the horizontal position in the cooling mode, dividing the cold air flow into two equal parts and introducing them into the air supply rollers 40. At this time, the same speed ensures that the ejection rates of the two air flows from the ventilation holes 41 are consistent. Combining with the mechanical movement in opposite directions, a mirror-symmetric air flow field is formed on the upper and lower surfaces or both sides of the material. The symmetry design can offset the air flow deviation that may be caused by the rotation of the air supply rollers 40, enabling the material to be covered by a uniform cooling air flow and avoiding the problem of uneven cooling caused by differences in air flow speed on one side.

[0049] Furthermore, the design with the same rotational speed makes the rotational frequencies of the two air supply rollers 40 consistent, avoiding mechanical resonance caused by rotational speed differences.

[0050] During the production and preparation of aluminum foam, impurities are likely to accumulate in the ventilation holes 41 of the air supply rollers 40 of the cooling system and on the surface of the aluminum foam material due to the production environment or process characteristics. During the cooling process of the aluminum foam material, fine debris, dust, or condensates may be generated. These substances will adhere to the inner wall of the ventilation holes 41 of the air supply rollers 40 along with the cold air flow. Long-term accumulation can easily lead to a reduction in the cross-sectional area of the flow channel or even complete blockage, affecting the uniform output of the cold air flow and the cooling efficiency.

[0051] Therefore, to ensure the long-term stability of the aluminum foam production process and the consistency of product quality, and to meet the requirements of industrial continuous production for equipment reliability and process continuity, a cleaning mode is set to clean the air supply rollers 40.

[0052] In the cleaning mode, the second motor 52 is driven to drive the deflector 30 to rotate within the flow dividing seat 20, the air compressor 11 is driven to operate at the second power, and the two first motors 51 are driven to rotate at different speeds and in opposite directions. The second power is greater than the first power. In the cleaning mode, the ratio of the rotational speeds of the two first motors 51 is 2.

[0053] When the system switches to the cleaning mode, the deflector 30 deviates from the horizontal position under the drive of the second motor 52, and the angle between itself and the inner wall of the flow expansion chamber 22 is changed by rotation, thereby adjusting the air flow distribution ratio between the two air supply rollers 40. At this time, the air compressor 11 operates at a second power higher than that in the cooling mode, generating a higher-pressure air flow. The angle change of the deflector 30 causes the flow rate of one air flow to increase and the other to decrease. Cooperating with the two first motors 51 to rotate the air supply rollers 40 at different speeds (the speed ratio is 2:1) in opposite directions, a differential air flow scouring intensity can be formed on the surface of the air supply rollers 40.

[0054] The air flow path with a larger flow rate can strongly blow the ventilation holes 41 and the material surface to remove the attached impurities or residual particles. The rotational speed difference further enhances the mechanical disturbance and air flow shear effect during the cleaning process through the difference in the linear speeds on the surface of the air supply rollers 40, achieving an efficient cleaning function.

[0055] When the two air supply rollers 40 rotate in opposite directions at different speeds, the linear speeds on their surfaces are different, resulting in different relative movement trajectories of the air flow ejected from the ventilation holes 41. The air compressor 11 operates at the second power (higher than that in the cooling mode) in the cleaning mode to output a high-pressure cold air flow. The deflector 30 adjusts the air flow distribution ratio by rotation, causing the flow rate of one air flow to increase and the other to decrease.

[0056] On one side of the air supply roller 40 with a larger flow rate, the high-pressure air flow cooperates with a higher rotational speed to form a stronger air flow shear force, which can effectively blow out the blockages in the ventilation holes 41 and the stubborn impurities on the surface of the material; on the side with a smaller flow rate, a lower rotational speed is combined with a relatively weaker air flow to perform a secondary cleaning of the material surface to avoid material damage caused by excessive scouring.

[0057] The high-speed air supply roller 40 can enhance the peeling effect on the particles on the material surface through the centrifugal force generated by rapid rotation; the low-speed air supply roller 40 ensures that the air flow has sufficient time to penetrate into the material gaps or the interior of the ventilation holes 41 through a slower movement rhythm.

[0058] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to include these modifications and variations.
