Abstract

The invention discloses an airflow suspension type screening machine. A screening box is arranged at the upper end of a rack, and a lower sealing cover is arranged at the upper end of the screening box. A vibration net plate device is arranged at the upper end of the lower sealing cover, and an upper sealing cover is arranged at the upper end of the vibration net plate device. 6-20 exhaust openings are formed in the upper end of the upper sealing cover, and exhaust connecting pipes are arranged at the upper ends of the exhaust openings. Pneumatic adjusting tee-joint valves are arranged at theupper ends of the exhaust connecting pipes, a centrifugal fan is arranged at the left end of the rack, and an exhaust header pipe is arranged at the front end of the centrifugal fan. An air outlet isformed in the right end of the centrifugal fan, and a blowing and dust removal connecting opening is formed in the right end of the air outlet. A lower blowing air pipe is arranged at the lower rightend of the blowing and dust removal connecting opening, and an upper blowing air pipe is arranged at the upper end of the lower blowing air pipe. A feeding conveying belt is arranged at the rear rightend of the rack, and a discharging conveying belt is arranged on the lower side of the vibration net plate device. The airflow suspension type screening machine is simple in structure, low in machining and production cost and good in dust removal, debris removal and sorting effect.

Description

technical field [0001] The invention relates to a cigarette processing machine, in particular to an air-flow suspended tobacco dedusting and screening machine for removing broken stems, chips and broken foam. Background technique [0002] During the processing and production of cigarettes, the shredded shred rate in shredded tobacco will directly affect the quality of the product. In order to effectively reduce the shredded shred index of finished cigarettes, it is necessary to reduce shredded shredded shreds below 1mm in shredded tobacco during the processing of shredded tobacco. During the drying process, the shredded shreds rate increases due to the decrease in moisture content and the influence of the drying process on the shredded tobacco. In order to ensure the quality of cigarettes, a screening device is required to remove the shredded stems and fragments produced during the cigarette production process. , debris and dust are screened out. At present, due to the desi...
