Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

As shown in fig. 1, an automatic powder material detecting apparatus 100 according to an embodiment of the present invention includes: sampling mechanism 10, grinding mechanism 20, transport mechanism 30, and analyzer 40.
First, the sampling mechanism 10 is adapted to automatically remove material samples from a production line of powder material. The sampling mechanism 10 can automatically sample at different stages on the powder material production line, and different sampling mechanisms 10 can be selected according to different production line settings. The structure of the sampling mechanism 10 is not particularly limited in this embodiment, as long as automatic material sample removal from the production line can be achieved. For example, the sampling mechanism 10 may be a pre-welded part, a disc-shaped shell is welded on the side wall of the air chute of the powder material production line, an opening channel is arranged on the pre-welded part, an opening matched and connected with the opening channel is arranged on the disc-shaped shell, and a stop block is also arranged on the disc-shaped shell. When powder material is sampled, the disc-shaped shell is communicated with the pre-welding piece through the opening and the opening channel, and when the powder material is not sampled, the opening and the opening channel are separated by a stop block on the disc-shaped shell. The disc-shaped shell is driven by the motor, and the sampling can be automatically controlled by controlling the motor to rotate, so that the operation of the powder material production line is not influenced. Of course, the sampling mechanism 10 of the present embodiment may also employ the structure described below.

It will be appreciated that there are many grinding mechanisms 20 for grinding materials into powder, and the structure of the grinding mechanism 20 is not particularly limited in this embodiment, as long as grinding of a sample of materials can be achieved. For example, the grinding mechanism 20 can be a three-roller grinder, wherein the material is fed into a natural hopper consisting of a middle roller, a rear roller and two baffles, and is subjected to reverse asynchronous rotation by the middle and rear rollers, so that the material is subjected to rapid turning and shearing to break the structural stress surface between the raw material molecules, and is subjected to high-speed secondary grinding by the middle and front continuous rollers, thereby achieving the purpose of grinding the material. Of course, the sampling mechanism 10 of the present embodiment may also employ the structure described below.
Further, a conveying mechanism 30 is connected with the grinding mechanism 20, and the conveying mechanism 30 is used for receiving and conveying the material samples ground by the grinding mechanism 20. There are many conveying mechanisms 30 for conveying powder materials, and the structure of the conveying mechanism 30 is not particularly limited in this embodiment, so long as the conveying of the material sample can be realized and the detection by the analyzer 40 is facilitated. For example, the conveying mechanism 30 may be a pneumatic conveying mechanism, which includes a sending device, a conveying pipeline, a material-gas separation device, a gas source and purification device, an electric instrument and the like, and the pneumatic conveying is a conveying method for conveying powdery materials in a pipeline by using air flow as a bearing medium. Of course, the conveying mechanism 30 of the present embodiment may also employ a structure described below.
Still further, an analyzer 40 is connected to the conveyor 30, the analyzer 40 being configured to analyze the material sample conveyed by the conveyor 30. Different indices need to be detected for different powder materials and the corresponding analyzer 40 needs to be used. For example, LIBS (Laser Induced Breakdown Spectroscopy ) technology focuses a sample surface by an ultrashort pulse laser to form a plasma, and then analyzes the plasma emission spectrum to determine the substance content and content of the sample. The LIBS technology can in principle analyze samples in any state of matter.
When the automatic powder material detecting device 100 detects powder materials, the sampling mechanism 10 automatically takes out material samples from the powder material production line.
