Separator of magnetic catalyst in hydrogenation catalytic reaction

The utility model belongs to the technical field of a separator, and discloses a separator of magnetic catalyst in hydrogenation catalytic reaction. The separator is mainly and technically characterized by comprising a pot body with an inlet pipe and an outlet pipe, wherein the outlet pipe is arranged at the top end of the pot body, and the outlet pipe is externally sheathed with an annular magnet which is connected with a crank connecting rod of a motor by a pull rod. When the separator of the magnetic catalyst in the hydrogenation catalytic reaction is used, the motor is driven by the crank connecting rod and the pull rod to lead the annular magnet to vertically move up and down. When the annular magnet is moved to a lowest place, magnetic catalyst grains move upwards and are agglomerated at the circular cavities of the bottom and the center of the annular magnet, and then the annular magnet moves upwards after being used for absorbing for a long time, so that the agglomerated magnetic catalyst grains are f
