Its equipment mainly includes: a gate valve, a vibrating feeder, a rotary seal valve, etc. The coke in the dry quenching furnace falls by gravity, passes through the gate valve and the vibrating feeder and enters the rotary seal valve, and then is discharged onto the conveyor belt. The positive pressure circulating gas in the dry quenching furnace is mainly sealed by the rotary seal valve. The existing utility model patent with the application number: CN201420302727.0 proposes an anti-jamming device for a dry coke quenching rotary seal valve, which includes a feed inlet, a discharge outlet and a discharge cylinder. The feed inlet is located at the upper part of the discharge cylinder, and the discharge outlet is located at the lower part of the discharge cylinder. The side wall of the discharge cylinder is an arc surface with the same curvature. An impeller with five blades is arranged in the discharge cylinder. It also includes a baffle plate. One side of the baffle plate is hinged to the end of the blade, and the other side abuts against the side wall of the discharge cylinder. The included angle between the blade and the baffle plate is an obtuse angle, and a return spring is fixedly connected between the blade and the baffle plate. The rotation direction of the impeller is the same as the inclination direction of the baffle plate. The utility model can ensure that the rotary seal valve will not be jammed during use without using a vibrating feeder. The foreign matters in the coke in the above patent are mainly ironware. The device is not convenient for separating the ironware in the coke and cannot collect the ironware uniformly, reducing the practicability of the device. Therefore, an anti-jamming rotary seal valve for a coke dry quenching furnace is provided to solve the above problems. Summary of the Utility Model

[0018] The second rotating shaft drives the first rotating shaft to rotate through the belt, and the first rotating shaft drives the magnetic roller to rotate.

[0019] The beneficial effects achieved by the present utility model are as follows: Through the arrangement of the magnetic roller, the first rotating shaft, and the second scraper, the first rotating shaft can be rotated to drive the magnetic roller to rotate. Coke slowly falls under the action of the rotating partition, and foreign objects (mainly ironware) in the coke will be magnetically attracted to the magnetic roller, while the coke will fall under the action of gravity and be discharged through the feeding chute.
