Description

Technical Field

[0001] This utility model belongs to the field of rapid drying technology for metal powders, specifically, it relates to a rapid drying device for metal powders. Background Technology

[0002] Drying is an indispensable and important step in the production and processing of metal powders. Traditional metal powder drying equipment has many defects. On the one hand, most traditional drying equipment adopts a static tray type or a simple rotary drum structure. In static tray drying, metal powder accumulates on the tray, and hot air can only slowly penetrate from the surface, resulting in extremely low drying efficiency.

[0003] On the other hand, traditional drying equipment is inadequate in preventing the agglomeration of metal powders. Due to their small particle size and large specific surface area, metal powders are extremely prone to adsorption and agglomeration in a humid state. Traditional equipment, whether through airflow disturbance or simple mechanical stirring, struggles to completely break up these agglomerates and prevent them from re-agglomerating during the drying process. This has a severely detrimental impact on subsequent high-precision processing of metal powders, such as 3D printing and precision forming in powder metallurgy, leading to unstable product quality and decreased mechanical properties. Furthermore, traditional drying equipment has a low level of automation, making it difficult to achieve precise and efficient operation in areas such as temperature control, material feeding and discharging, and drying process monitoring. This necessitates a significant investment of manpower, increasing production costs and the risk of human error. Therefore, this utility model is proposed to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rapid drying device for metal powder that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a metal powder rapid drying device, including a box body, and a rotating shaft rotatably connected to the box body. A longitudinal spiral blade is fixedly connected to the rotating shaft, a connecting rod is fixedly connected to the rotating shaft, and a transverse stirring blade is fixedly connected to the connecting rod. Multiple adjusting seats are fixedly connected to the bottom and inner wall of the box body. An airflow nozzle is rotatably connected to the adjusting seat, and an adjusting rod is slidably connected inside the airflow nozzle.

[0006] Furthermore, a cover plate is snapped onto the box, and a handle is fixedly connected to the cover plate. Multiple rollers are rotatably connected to the bottom of the box.

[0007] Furthermore, the adjusting seat has an adjusting groove, which is semi-circular.

[0008] Furthermore, a nozzle is provided through the airflow nozzle, and an adjusting rod is slidably connected inside the nozzle, with a tension spring fixedly connected to the adjusting rod.

[0009] Furthermore, multiple longitudinal helical blades are arranged in a helical shape on the rotating shaft.

[0010] Furthermore, the adjustment seat at the bottom of the box corresponds to the horizontal stirring blades.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0012] 1. The metal powder of this invention can obtain just the right lateral thrust, thereby achieving sufficient tumbling and ensuring that the powder in each position has an equal opportunity to come into contact with heat and airflow. When the airflow is ejected from the airflow nozzle, it intertwines and collides with the metal powder that is being spirally stirred, forming a wonderful synergistic effect. Whether the powder is near the core area of ​​the stirring shaft or in the corners of the drying chamber, it can be instantly surrounded by heat under this combined action and complete the evaporation and drying process in a very short time.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] Example: Refer to Figures 1-4 A rapid drying device for metal powder includes a housing 1 and a rotating shaft 2 rotatably connected to the housing 1. A longitudinal spiral blade 21 is fixedly connected to the rotating shaft 2, a connecting rod 22 is fixedly connected to the rotating shaft 2, and a transverse stirring blade 23 is fixedly connected to the connecting rod 22.

[0022] Multiple adjusting seats 3 are fixedly connected to the bottom and inner wall of the housing 1. An airflow nozzle 32 is rotatably connected to the adjusting seat 3. An adjusting rod 34 is slidably connected inside the airflow nozzle 32.

[0023] A cover plate 11 is snapped onto the box body 1, and a handle 12 is fixedly connected to the cover plate 11. Multiple rollers 13 are rotatably connected to the bottom of the box body 1.

[0024] The adjusting seat 3 has an adjusting groove 31, which is semi-circular;

[0025] A nozzle 33 is provided through the airflow nozzle 32. An adjusting rod 34 is slidably connected inside the nozzle 33. A tension spring 35 is fixedly connected to the adjusting rod 34.

[0026] Multiple longitudinal spiral blades 21 are arranged in a spiral shape on the rotating shaft 2;

[0027] The adjustment seat 3 at the bottom of the box 1 corresponds to the horizontal stirring blade 23;

[0028] In use, the lid 11 is opened by lifting the handle 12 on the top of the housing 1, allowing the metal powder to be introduced. As the shaft 2 is driven by the built-in drive motor, the metal powder exhibits a highly complex and efficient motion during the stable rotation of the longitudinal spiral blades 21. Axially, the metal powder, propelled by the longitudinal spiral blades 21, is given an orderly flow, continuously circulating. Radially, due to the special variable-angle design of the transverse stirring blades 23, the metal powder receives just the right lateral thrust, achieving thorough tumbling and ensuring that the powder in each position has an equal opportunity to come into contact with heat and airflow. Simultaneously, multiple sets of adjustable-angle and adjustable-volume airflow nozzles 3 are arranged at the bottom and sides of the housing 1. 2. These airflow nozzles 32 are like precise energy output ports. They can be adjusted at a certain angle on the adjustment groove 31 on the adjustment seat 3 according to the different characteristics of metal powders and the needs of the drying stage. The adjustment rod 34 slides inside the nozzle 33 while adjusting the size of the nozzle 33, flexibly adjusting the jet angle and air volume. When the airflow is ejected from the airflow nozzle 32, it intertwines and collides with the metal powder that is being spirally stirred, forming a wonderful synergistic effect. Whether it is powder near the core area of ​​the stirring shaft or powder at the edge corner of the drying chamber, it can be instantly surrounded by heat under this combined action and complete the evaporation and drying process of moisture in a very short time.
