Abstract
The utility model relates to a deviated feeder capable of conducting peripheral end dynamic compensation and sealing. According to an existing feeder, the peripheral end is sealed but the sealing effect is not ideal, after the feeder is used for a certain period, a shell body and an impeller are severely abraded, a gap between the impeller and the inner wall of the shell body is increased, wind leakage and material leakage are increased, and the effect of pneumatic transmission is severely influenced. The deviated feeder capable of conducting peripheral end dynamic compensation and sealing comprises a machine shell (3) provided with a feeding port (1) and a discharging port (2). An impeller set (4) is installed in the machine shell, a cavity is formed between each of the two side faces of the machine shell and the impeller set, a dynamic compensation sealing unit is installed in each cavity, and an outer cover board (5) covers the outer side of each cavity; one side of the machine shell is opened and then is provided with an exhaust pipe (6) and an access hole (7) is formed in the portion, located below the impeller set, of the machine shell. The deviated feeder capable of conducting peripheral end dynamic compensation and sealing is used for conducting peripheral end sealing and abrasion compensation on the impeller of the feeder.
