Abstract
Description
Technical Field
[0001] This utility model belongs to the field of powder metallurgy technology, specifically relating to a metal powder confinement calcination device. Background Technology
[0002] In the processing of metallic materials, powder calcination is a crucial step. Traditional metal powder calcination methods often suffer from low efficiency, high energy consumption, and uneven calcination, severely impacting the quality and performance of the metal powders. To address these issues, the industry has been committed to developing novel metal powder calcination equipment to improve calcination efficiency and product quality.
[0003] However, existing metal powder calcination equipment still has some shortcomings in practical applications. For example, the calcination vessels of some devices have a single shape, which cannot fully meet the flow and mixing requirements of metal powder during the calcination process, resulting in uneven calcination. In addition, the feeding and discharging systems of some devices are not perfect, which can easily cause powder blockage or leakage, affecting the stability and reliability of the device. At the same time, existing calcination equipment also has certain limitations in terms of energy consumption and environmental protection, making it difficult to meet the requirements of modern industry for green and efficient production.

Detailed Implementation
[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] A metal powder confinement calcination device, as shown in the attached... Figure 1-3As shown, the device includes a frame 1, which serves as the supporting structure for the entire device, providing stable support for other components. Two slide blocks 2 are symmetrically mounted on the frame 1, and a tank body 3 is rotatably mounted on each slide block 2. The slide blocks 2 support and rotate the tank body 3. The tank body 3 is generally olive-shaped, with slide rails 4 fixed to the outer sides of both ends. The tank body 3 is slidably connected to the slide blocks 2 via the slide rails 4. A rotating shaft 5 is installed inside the tank body 3. Sheaths I 6 and II 7 are fixedly connected to the frame 1 and respectively fitted onto both ends of the tank body 3. A feeding assembly passes through sheath I 6. A discharge port 8 is located below the tank body 3, inside sheath II 7. Several lifting ribs I are evenly distributed inside the tank body 3. 9. The lifting ribs I9 near the sheath I6 are oriented in the opposite direction to those near the sheath II7. The design of these lifting ribs I9 helps to ensure the uniform distribution and calcination of the metal powder. When the material is transferred to the discharge port 8 under the action of the lifting ribs I9, as the diameter of the tank 3 decreases, and the lifting direction of the tail lifting ribs I9 is opposite to that at the inlet 11, the combined effect of the two causes the material to fall back into the middle heating zone, avoiding insufficient heating. A rapping assembly is provided on the outer side of one end of the sheath II7 of the tank 3. The rapping assembly is fixed to the frame 1. The rapping assembly helps to prevent the metal powder from adhering to the inner wall of the tank 3 and improves the calcination efficiency.
[0030] For details, see attached. Figure 4 As shown, the feeding assembly includes a feeding trough 10, which is fixedly connected to the sheath I6. One end of the feeding trough 10 has a feed inlet 11. Two feeding motors 12 are fixedly mounted on the end of the feeding trough 10 near the feed inlet 11. The output ends of the two feeding motors 12 are all fixedly connected to a spiral feeding shaft 13. The feeding assembly adopts a double spiral feeding shaft 13, which is beneficial to the uniformity of feeding and avoids blockage during the feeding process.
[0031] For details, see attached. Figure 5 As shown, the rapping assembly includes a rotary motor 14 fixed to the frame 1. The output end of the rotary motor 14 is fixedly connected to a drive shaft 15. The drive shaft 15 is rotatably connected to the frame 1 via a support rod 29. A rapping hammer 16 is fixedly connected to the drive shaft 15. The rapping hammer 16 includes a connecting rod 161. The connecting rod 161 is rotatably connected to a hammer handle 162. A limiting rod 163 is fixedly provided on the hammer handle 162. A hammer head 164 is rotatably connected to the end of the hammer handle 162 away from the connecting rod 161. When the rotary motor 14 starts, it drives the drive shaft 15 to rotate. The drive shaft 15 drives the connecting rod 161 to rotate, which in turn drives the hammer handle 162 to rise upward. After reaching the highest point, it falls down to rappel the tail of the tank 3. Under the action of the limiting rod 163, the hammer handle 162 can be prevented from falling down before reaching the designated position during the lifting process, thus affecting the rapping effect.
[0032] For details, see attached. Figure 1 As shown, a gear ring 17 is fixedly provided on the outer side of the tank body 3 near the sheath I6. A servo motor I18 is provided below the gear ring 17 on the frame 1. A gear I19 is fixedly provided at the output end of the servo motor I18. The gear I19 meshes with the gear ring 17.
[0033] Further details are attached. Figure 1 As shown, several lifting ribs II20 are staggered on the rotating shaft 5. The function of the lifting ribs II20 is to further stir the powder so that the powder is calcined more completely.
[0034] For details, see attached. Figure 6 As shown, the two ends of the rotating shaft 5 are rotatably connected to the frame 1. A gear II21 is fixedly connected to one end of the rotating shaft 5 near the sheath II7. A servo motor II22 is fixedly mounted on one side of the gear II21. A gear III23 is fixedly mounted at the output end of the servo motor II22. The gear II21 meshes with the gear III23.
[0035] For details, see attached. Figure 1 As shown, in order to heat and calcine the powder, a steel frame 24 is provided on the outer side of the tank body 3, and a coil 25 is fixed on the steel frame 24. The coil 25 is sleeved on the outside of the tank body 3.
[0036] Further details are attached. Figure 1 As shown, in order to monitor the temperature in real time during the calcination process, several thermocouples 26 are fixed on the top of the steel frame 24.
[0037] Further details are attached. Figure 1 As shown, in order to centrally process the gas generated during the calcination process, the sheath I6 is provided with an exhaust port 27, and the sheath II7 is provided with an air inlet 28.
[0038] For details, see attached. Figure 7 As shown, the discharge port 8 is fixedly connected to the sheath II 7 and extends out of the frame 1 and is located at the bottom of the frame 1.
[0039] Working principle
[0040] As attached Figure 1-7As shown, the powder is first fed into the tank 3 by the feeding assembly, and then heated and calcined by the coil 25. During the calcination process, the tank 3 is rotated by a servo motor, and the lifting ribs inside the tank 3 agitate the material. Since the tank 3 is olive-shaped, when the material is transferred to the outlet 8 under the action of the lifting ribs I9, as the diameter of the tank 3 decreases, and the lifting direction of the tail lifting ribs I9 is opposite to that at the inlet 11, the combined effect of the two causes the material to fall back into the middle heating zone, allowing it to be fully calcined. At the same time, the rapping assembly at the tail of the tank 3 can prevent the powder from adhering to the inner wall of the tank 3, improving the calcination efficiency. Through the rotating shaft 5, on which several lifting ribs II20 are staggered, the powder can be further agitated, making its calcination more complete.
