Screening dust pumping and discharging device for sesame processing

The invention belongs to the technical field of dust escape prevention equipment, and particularly relates to a dust screening and pumping device for sesame processing, which comprises a sealing cover, a circulating pump and filtering equipment, and further comprises a circulating pumping assembly, the circulating pumping assembly is mounted on the sealing cover, the circulating pumping assembly is communicated with the circulating pump through a pipeline, and the filtering equipment is connected with the circulating pump through a pipeline. The circulating pumping and discharging assembly is used for dynamically pumping air in the filtering chamber; according to the invention, the circulating pumping and discharging assembly is arranged, a plurality of uniformly distributed filter pipes are utilized to perform multi-point pumping on dust in the filter chamber, so that the local airflow pumping strength is reduced, and meanwhile, an electric telescopic rod is driven to perform telescopic motion, so that the t
