Technical Field

[0001] This utility model relates to the field of powder sampling technology, specifically to an online rapid quantitative powder sampling device. Background Technology

[0002] In the vacuum atomization powder production process, quantitative sampling and testing of the powder during the process is a crucial step in ensuring powder quality. Manual sampling is difficult to perform quantitatively and introduces oxygen into the powder, potentially contaminating it and posing a risk of explosion due to static electricity, thus threatening the safety of workers. Existing technologies also employ powder samplers, such as the fixed powder sampler disclosed in Chinese Patent Publication No. CN219551945U. However, this device uses a high-speed rotating screw that comes into contact with the powder, easily generating static electricity and creating a risk of pipeline explosion, and it also makes quantitative sampling difficult.

Therefore, they should not be construed as limitations on this utility model.

[0022] See Figures 1-2 This embodiment discloses an online rapid quantitative powder sampling device, including a powder container 1, a powder conveying mechanism 2, a powder sampling tank 3, and a weighing mechanism 4. The powder container 1 is the original carrier container for atomized powder production, and the powder sampling tank 3 is the carrier container for sampling powder. The powder conveying mechanism 2 is connected between the powder container 1 and the powder sampling tank 3, and is used to quantitatively convey the powder in the powder container 1 to the powder sampling tank 3. The weighing mechanism 4 is connected to the powder sampling tank 3 and is used for quantitative feedback of the powder.

[0023] like Figure 1 As shown, the powder conveying mechanism 2 includes a first conveying pipe 21 arranged horizontally and an auger conveying screw 22 rotatably connected in the first conveying pipe 21. The first conveying pipe 21 is connected to the side end of the powder container 1 through a clamp joint 23, and one end of the auger conveying screw 22 extends into the powder container 1. The auger conveying screw 22 is driven by a motor 24 fixedly connected to the other end of the first conveying pipe 21.

[0024] Combination Figure 3 In this embodiment, the bottom of the first conveying pipe 21 is provided with a discharge port 211 for powder discharge. A vertically arranged second conveying pipe 25 is connected through this discharge port 211, and the discharge end of the second conveying pipe 25 is connected to the inlet end of the powder sampling tank 3. Furthermore, the powder in the powder container 1 enters the first conveying pipe 21 through the auger screw 22, falls into the second conveying pipe 25 by its own weight at the discharge port 211 of the first conveying pipe 21, and then enters the powder sampling tank 3 through the second conveying pipe 25. This automatic powder conveying structure avoids direct contact between personnel and powder samples, thus preventing powder contamination and reducing safety risks.

[0025] See Figure 1 The weighing mechanism 4 is located at the bottom of the powder sampling container 3, and includes a weighing base 41, a weight sensor 42 fixedly connected to the top surface of the weighing base 41, and a weighing platform 43 connected to the top of the weight sensor 42. The powder sampling container 3 is placed on the weighing platform 43.

[0026] To cooperate with the weighing mechanism 4, in this embodiment, the first conveying pipe 21 and its related supporting structures are supported by an external fixing structure; the second conveying pipe 25 is a flexible hose, such as a silicone hose or a rubber hose, preferably a transparent flexible hose, so as to observe the powder falling inside. In this embodiment, the weight sensor 42 is linked with the motor 24 used to control the rotation of the auger conveying screw 22, and controls the motor 24 to start or stop according to the required powder weight.

[0027] See Figure 1 and Figure 2Furthermore, to prevent oxygen from entering the powder sampling tank 3, the powder conveying mechanism 2 also includes a first valve body 26 and a second valve body 27 connected to the second conveying pipe 25. The first valve body 26 is connected between the outlet 211 of the first conveying pipe 21 and the inlet of the second conveying pipe 25, and the second valve body 27 is connected between the outlet of the second conveying pipe 25 and the powder sampling tank 3. The first valve body 26 is preferably a pneumatic butterfly valve, which is connected to the outlet 211 of the first conveying pipe 21 and the inlet of the second conveying pipe 25 via sealing clamps 28. The first valve body 26 starts or closes synchronously with the motor 24. When the motor 24 drives the auger conveying screw 22 to rotate, the pneumatic butterfly valve opens; when the motor 24 closes, the pneumatic butterfly valve closes, thereby preventing oxygen from entering the second conveying pipe 25 and the powder sampling tank 3, thus avoiding powder contamination or deflagration upon contact with oxygen. The second valve body 27 is preferably a manual butterfly valve, which is connected to the discharge end of the second conveying pipe 25 and the inlet end of the powder sampling tank 3 respectively through a sealing clamp 28. When the powder sampling tank 3 reaches the preset weight, the manual butterfly valve is closed and the sealing clamp 28 away from the powder sampling tank 3 is opened, so that the powder sampling tank 3 can be sealed and removed.

[0028] See Figure 4 In this embodiment, the powder sampling container 3 further includes an inner shell 31 and an outer shell 32 fitted over the inner shell 31. The inner shell 31 is made of transparent glass to facilitate observation of the volume of powder contained within it. The outer shell 32 is preferably made of hard steel for easy transport, and its outer wall is constructed with spaced vertical partitions 321 to prevent complete obstruction of the inner shell 31. Preferably, the partitions 321 of the outer shell 32 are also coated with a graduation layer 33 to facilitate estimation of the weight of the powder inside.

[0029] See Figure 1 To prevent static electricity from being generated during powder conveying, the sampling device also includes an anti-static mechanism 5 connected to the first conveying pipe 21. In this embodiment, the first conveying pipe 21 is made of stainless steel. Specifically, the outer wall of the first conveying pipe 21 has a connecting post 212 protruding radially outward near the powder container 1. The anti-static mechanism 5 includes a copper core wire 51 fixedly connected to the connecting post 212 and a copper clip 52 fixedly connected to the other end of the copper core wire 51. In application, the copper clip 52 is clamped onto the anti-static post. It should be noted that the post should be made of metal and pre-buried about 1 meter underground.

[0030] It is understood that in this embodiment, the above-mentioned actions are all controlled by a control system. The control system may specifically include a controller or microcontroller that can control multiple mechanisms according to a predetermined program, so that the powder conveying mechanism 2 and the weighing mechanism 4 can start, stop or perform other actions according to a preset process.

[0031] The sampling device provided in this embodiment can realize automatic online rapid quantitative sampling of atomized powder, avoiding the risks of powder contamination and safety risks caused by manual sampling. At the same time, this embodiment can achieve accurate quantitative sampling through the linkage weighing mechanism 4 and the scale layer 33 of the powder sampling tank 3. The double valve structure connected to the second conveying pipe 25 can also prevent oxygen from mixing in, reducing the possibility of powder contamination and deflagration. Furthermore, the anti-static mechanism 5 can further reduce the risk of pipeline or powder deflagration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
