Description

Technical Field

[0001] The utility model relates to the technical field of limestone sampling in cement manufacturing production, in particular to an automatic limestone sampler. Background Art

[0002] Limestone is an important component of cement. The composition and particle size quality of limestone will directly affect the subsequent properties of cement. Therefore, it is necessary to sample and inspect the limestone after crushing during the cement production process. In the Chinese patent with authorization announcement number CN209542168U, an online limestone automatic sampler for cement production is disclosed. The material is received through a receiving assembly and can be used on site in a timely manner without advance preparation, which effectively improves work efficiency, has low manufacturing cost and is simple to operate. However, during the sampling process, the device is prone to clogging the discharge port due to the presence of unprocessed large particles of limestone in the feeding pipe, delaying the sampling progress. The staff needs to clear the discharge port before resuming sampling, which reduces the efficiency of sampling and increases the workload of the staff. In addition, the sampler cannot take samples from the first discharge point after the limestone is crushed, and its practicality is poor. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content
