Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device. Background Art

[0002] Against the backdrop of growing energy demand and increasingly stringent environmental protection requirements, lithium iron phosphate (LiFePO4)-based lithium-ion batteries, as a high-performance, highly stable, economical, and environmentally friendly new energy carrier, are experiencing strong growth. The quality of LiFePO4 cathode materials, the core component of LiFePO4 batteries, directly determines their performance and service life.

[0003] Accurate and efficient sampling, inspection, and analysis of solid powder during the production of lithium iron phosphate cathode materials is crucial for ensuring the performance of the finished cathode material. This process typically utilizes sampling devices to precisely sample and inspect key points in the production process, effectively controlling and optimizing the production process to ensure stable and consistent product quality.

[0004] To further meet the production needs of lithium-ion battery cathode materials for high production efficiency, excellent product quality, and low safety risks, the industry is gradually shifting from process node sampling devices to automated sampling. For example, the utility model patent with publication number CN218411718U describes a solution that replaces manual sampling of ferroalloys, achieving high randomness, strong representativeness, and the avoidance of human intervention. However, after sampling, cleaning the interior of the device is inconvenient. If residual powder is not cleaned thoroughly, it can contaminate the sample during subsequent sampling, making it difficult to accurately reflect the true characteristics of the overall material, which can easily lead to deviations in subsequent analysis and quality control.

[0024] In this specific embodiment, the air inlet on the mounting base 2 that is in communication with the blowing member 6 corresponds to the discharge port.

[0025] In this specific embodiment, the driving member 5 is a forward and reverse motor, which is fixedly connected to the mounting base 2 and the output shaft is fixedly connected to one end of the rotating shaft 3; the blowing member 6 is an air pump, which is fixed on the mounting base 2; in addition, the discharge valve 21 is also connected to a delivery pipe 22, wherein the delivery pipe 22 is a telescopic hose.

[0026] On the basis of the above scheme, in order to prevent part of the powder from adhering to the inner wall of the mounting seat, specifically, the sampling device also includes a mounting rod 7 and at least one scraper 8, the mounting rod 7 is arranged in the mounting seat 2 and is fixedly connected to one end of the rotating shaft 3, and at least one scraper 8 is fixedly connected to the mounting rod 7 and fits against the inner wall of the mounting seat 2.

[0027] In this specific embodiment, two scrapers 8 are connected to the mounting rod 7 , and the scrapers 8 rotate with the rotating shaft 3 to scrape off the powder attached to the inner wall of the mounting seat 2 .

[0028] On the basis of the above scheme, in order to avoid the accumulation of powder in the mounting seat and the difficulty of unloading, specifically, multiple stirring rods 9 are arranged at intervals on the scraper 8; in this specific embodiment, the axes of the multiple stirring rods 9 are perpendicular to the axis of the rotating shaft 3.
