Description

Technical Field

[0001] This utility model relates to the technical field of magnetic powder measuring devices, specifically a magnetic powder measuring device. Background Technology

[0002] In the production and processing of magnetic powder, it is often necessary to detect the powder to determine whether there is material inside the container and to help determine the position of the material inside the container. For the production and processing of magnetic powder, it is necessary to ensure that the outer wall of the container is uniform and continuous to ensure the structural strength of the container. Therefore, it is not advisable to set up an observation window to determine the material level. Existing powder detection devices generally directly contact the material with the sensor or use a gravity sensor to directly measure the material level. However, this method of measurement is not suitable for magnetic powder with magnetic properties.

[0003] Chinese patent document CN217101360U discloses a powder tank level control and automatic arch breaking device, which realizes the function of displaying the powder tank level and automatically breaking the arch, thus improving production efficiency. However, it does not disclose how to make adaptive improvements for magnetic powder to ensure the accuracy of the measurement results.

[0004] Chinese patent document CN220084129U discloses an anti-impact structure for a multi-stage vacuum pump, which uses a weight sensor to detect the gravity of the accumulated dust to determine the dust level, but does not disclose how to solve the problem of inaccurate magnetic particle measurement.
