Description

Technical Field

[0001] This utility model relates to the technical field of alloy powder production equipment, and in particular to a cooling device for alloy powder production. Background Technology

[0002] In the production process of alloy powder, the alloy raw materials need to undergo key processes such as melting and atomization under high temperature conditions to finally form fine powder particles. This process has strict requirements for temperature control to ensure that the powder composition is uniform, the particle size distribution is reasonable, and the material performance requirements of subsequent applications are met. However, after atomization into powder, the newly formed alloy powder is still in a high temperature state. If it is not cooled in time and uniformly, it is very easy to cause local sintering or surface oxidation between particles, which not only reduces the flowability and bulk density of the powder, but may also affect its performance in additive manufacturing, powder metallurgy and other fields.

[0003] Currently common cooling devices lack powder dispersion structures, making it impossible to achieve effective disturbance and uniform distribution during powder falling or conveying. This leads to high-temperature alloy powders easily accumulating in localized areas, hindering rapid heat conduction and convection dissipation, resulting in low heat dissipation efficiency and uneven temperature distribution. At the same time, the powder particles have been in contact for too long at high temperatures, resulting in high surface activity and making them prone to mutual adhesion, sintering, and even oxidation. After cooling, they exhibit obvious agglomeration and clumping, which not only destroys the uniformity of powder particle size distribution but also significantly reduces its flowability, filling ability, and compatibility with subsequent processes, seriously affecting the density and mechanical properties of the final product.

[0004] Therefore, a cooling device for alloy powder production needs to be designed. Utility Model Content

Cams are connected to the output shafts of each motor 2, and rotating rods are rotatably connected between the cams and the corresponding fixed blocks.

[0009] To further explain, the water-cooling assembly includes a water storage tank, an outlet pipe, a sealing cap, a cooling water pipe, a water pump, and a second solenoid valve. The water storage tank is fixedly connected to the left side of the cooling chamber, and a sealing cap is threadedly connected to the top of the water storage tank.

[0012] Beneficial effects: 1. Through the stirring rack and vibration component, the stirring rack continuously stirs the powder under the three-drive of the motor, breaking the contact interface between particles. At the same time, the vibration component generates high-frequency vibration through cam and spring, which makes the powder attached to the inner wall of the cooling chamber fall off in time and shakes away the small agglomerates that have been formed.

Detailed Implementation

[0024] Example: A cooling device for alloy powder production, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the assembly includes a cooling chamber 1, a controller 2, a temperature sensor 201, a feeding assembly, a motor 3 14, a pinion 15, a mixing rack 16, a large gear 17, a discharge pipe 18, a solenoid valve 19, a vibration assembly, and a water cooling assembly. The controller 2 is installed on the front of the cooling chamber 1. The controller 2 is a Siemens S7-200 SMART. The SR30 model has a temperature sensor 201 installed on the inner wall of the cooling chamber 1 to monitor the powder temperature in real time. The cooling chamber 1 is equipped with a feeding assembly, and a motor 14 is installed on the top of the cooling chamber 1. A small gear 15 and two large gears 17 are rotatably connected to the top of the cooling chamber 1. The output shaft of the motor 14 is connected to the small gear 15. The large gears 17 mesh with the small gears 15. A stirring frame 16 is welded to the bottom of each of the large gears 17 to prevent powder from accumulating at the bottom of the cooling chamber 1 and causing insufficient cooling in some areas. The stirring frame 16 passes through the cooling chamber 1 and is rotatably connected to it. A discharge pipe 18 is welded to the bottom of the cooling chamber 1, and a solenoid valve 19 is installed on the discharge pipe 18. The temperature sensor 201, the motor 14, and the solenoid valve 19 are all electrically connected to the controller 2. The cooling chamber 1 is equipped with a vibration assembly and a water cooling assembly.

[0025] like Figure 1 and Figure 3 As shown, the feeding assembly includes a feeding frame 3, a motor 4, a feeding hopper 5, and a screw conveyor 6. The feeding frame 3 is welded to the right side of the cooling chamber 1. The motor 4 is installed on the right side of the feeding frame 3. The motor 4 is electrically connected to the controller 2. The feeding hopper 5 is welded to the top of the feeding frame 3. The screw conveyor 6 is rotatably connected inside the feeding frame 3.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the vibration assembly includes limit rods 7, support frame 8, springs 9, fixing blocks 10, motor 11, cams 12, and rotating rods 13. Four limit rods 7 are welded to the bottom of the cooling chamber 1 along the axial direction. The limit rods 7 can guide the cooling chamber 1 and prevent it from deviating. The support frame 8 is slidably connected to the four limit rods 7 through a sliding groove. Four springs 9 are connected between the cooling chamber 1 and the support frame 8. The springs 9 are all sleeved on the outside of the limit rods 7. Fixing blocks 10 are welded to the front and rear sides of the outside of the cooling chamber 1. Motors 11 are installed on the front and rear sides of the outside of the support frame 8. Motors 11 are electrically connected to the controller 2. Cams 12 are connected to the output shaft of motors 11. Rotating rods 13 are rotatably connected between the cams 12 and the corresponding fixing blocks 10. This can remove the powder adhering to the inner wall of the cooling chamber 1 and disperse the clumps of powder, ensuring that the powder is always in a loose state, which not only ensures the uniformity of mixing but also avoids clogging of the discharge pipe 18 when discharging.

[0027] like Figure 1 , Figure 5 and Figure 7 As shown, the water-cooling assembly includes a water storage tank 20, a water outlet pipe 2001, a sealing cap 21, a cooling water pipe 22, a water pump 23, and a second solenoid valve 24. The water storage tank 20 is welded to the left side of the cooling chamber 1, and the sealing cap 21 is threaded to the top of the water storage tank 20. The cooling water pipe 22 is welded inside the cooling chamber 1. The cooling water pipe 22 is distributed in an S-shape on the inner wall of the cooling chamber to effectively increase the contact area with the powder. The left side of the cooling water pipe 22 passes through the cooling chamber 1 and is connected to the water storage tank 20. The water pump 23 is installed on the left side of the cooling water pipe 22. The water outlet pipe 2001 is welded to the lower left side of the water storage tank 20. The second solenoid valve 24 is installed on the water outlet pipe 2001. After cooling is completed, the circulating hot water can be automatically discharged through the second solenoid valve 24 to avoid residual scale. The water pump 23 and the second solenoid valve 24 are both electrically connected to the controller 2.

[0028] like Figure 2 and Figure 8 As shown, it also includes an air-cooling component. The air-cooling component is installed on the cooling chamber 1. The air-cooling component includes a fixed frame 25, a fan 26, a fixed pipe 27, a connecting pipe 28, a nozzle 29, and a filter screen 30. The fixed frame 25 is welded to the upper front side of the cooling chamber 1. Two fans 26 are installed inside the fixed frame 25. Both fans 26 are electrically connected to the controller 2. The fixed pipe 27 is welded inside the cooling chamber 1. Two connecting pipes 28 are welded between the fixed pipe 27 and the fixed frame 25. Eight nozzles 29 distributed along the axial direction are welded inside the fixed pipe 27. The fixed frame 25, the connecting pipe 28, the fixed pipe 27, and the nozzles 29 are interconnected. The filter screen 30 is welded to the front inside the fixed frame 25, which can filter the incoming cooling air, effectively isolate external impurities, and ensure powder purity and surface quality.

[0029] When this device is needed, the operator first rotates the sealing cover 21 to open the water storage tank 20, pours in sufficient cooling water, and then reverses the sealing cover 21 to close the water storage tank 20. Next, the operator can start motor 4, motor 14, water pump 23, and fan 26, and pour the high-temperature alloy powder to be cooled into the feeding hopper 5. The alloy powder slides down the inner wall of the feeding hopper 5 into the feeding frame 3. Motor 4 starts, driving its upper output shaft to rotate, thereby driving the screw conveyor 6 to rotate within the feeding frame 3. The screw conveyor 6, through the rotation of its spiral blades, evenly and continuously pushes the alloy powder in the feeding frame 3 into the cooling chamber 1. Motor 14 starts, driving its upper output shaft to rotate, thereby driving the small gear 15 to rotate. Due to the rotation of the two large gears 1... All 7 mesh with the small gear 15, which drives the two large gears 17 to rotate in opposite directions. The stirring frame 16 rotates synchronously with the large gears 17. The stirring blades of the stirring frame 16 penetrate into the alloy powder in the cooling chamber 1 to continuously stir the powder. At the same time, the water pump 23 starts to pressurize the cooling water in the water storage tank 20 and deliver it to the cooling water pipe 22. When the cooling water circulates in the cooling water pipe 22, it absorbs the heat of the alloy powder in the cooling chamber 1 through heat conduction, achieving initial cooling. The fan 26 operates to further generate cold air. After being filtered by the filter screen 30, the cold air is delivered to the fixed pipe 27 through the connecting pipe 28. Finally, it is evenly sprayed onto the surface of the alloy powder in the cooling chamber 1 by multiple nozzles 29, quickly removing the heat from the powder surface.

[0030] During the cooling and stirring process, the vibration component can be activated as needed. When activation is required, the motor 11 is started by the controller 2. The output shaft of the motor 11 rotates, driving the cam 12 to rotate. The cam 12 pushes the fixed block 10 to move through the rotating rod 13, causing the limit rod 7 to slide up and down along the support frame 8. The spring 9 continuously expands and contracts with the vibration of the cooling chamber 1, generating high-frequency vibration, which dislodging the powder adhering to the inner wall of the cooling chamber 1 and dispersing the clumps of powder, ensuring that the powder is always in a loose state.

[0031] After the material feeding is completed, motor 4 is turned off. Temperature sensor 201 monitors the temperature of the alloy powder in real time. When the temperature of all alloy powder in cooling chamber 1 drops to the preset threshold, the operator confirms and turns off water pump 23 and fan 26 through controller 2. Stirring rack 16 continues to rotate. When the cooled alloy powder needs to be removed, solenoid valve 19 is opened through controller 2. Under the pushing action of gravity and stirring rack 16, the alloy powder in cooling chamber 1 is discharged at a uniform speed along discharge pipe 18. The discharged powder can directly enter the next production process or be packaged. After the material is discharged, the user turns off motor 21 and solenoid valve 19 in sequence through controller 2. Then, solenoid valve 24 is opened through controller 2 to discharge the heat-conducted hot water through water outlet pipe 2001. After the discharge is completed, solenoid valve 24 is closed, thus completing the use of this device.
