[0001] The invention belongs to the technical field of cement production detection, and in particular relates to a sample preparation device for an intelligent storage system of factory cement and a use method thereof. Background Art

[0002] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0003] There is generally a lot of dust and scattered locations at the sampling points for cement leaving the factory. Sampling in this environment for a long time will cause harm to the health of employees. If manual labor is required to climb to the roof of the vehicle and take samples through the loading port every time, there will be positive pressure at this location, which may pose a threat to the personal safety of employees.

[0004] Manually, in the case of the same batch, it is necessary to sample each truck or bag of cement, and take the final sample after mixing. The sample preparation work is labor-intensive, time-consuming, and has a high consumption of manpower.

[0005] Manual operation not only causes health problems, but may also affect efficiency and quality.

[0006] Manual sampling is less representative: Manual sampling generally only allows for instantaneous and partial sampling, and is unable to achieve full-section and multi-frequency sampling. Combined with various uncertainties in manual sampling, this will lead to poor representativeness of the sampling;

[0007] Manual sample delivery has low timeliness: Since cement plants are generally large, sampling points are relatively scattered and far away from laboratory buildings and sample storage rooms, manual transportation takes a long time, the samples collected have a certain lag, poor timeliness, and high labor intensity. Summary of the invention
