It is uneven, influence the attractive in appearance of finished catalyst.
In order to solve the above problems, the present invention provides following technical scheme：
Catalyst granulator includes cylinder casement and the pressure wheel with cylinder casement inscribe；Cylinder casement inwall is provided with
Feeding-passage；Feeding-passage has inlet and outlet；Inlet communication has feed hopper, exports tangent towards cylinder casement and pressure wheel
Place；Multiple through holes are uniformly provided with cylinder casement outer wall.
Further, it is provided with solid post in through hole；The side wall of solid post is connected with connecting rod, and the free end of connecting rod is with leading to
The inwall connection in hole.
Specifically, it is at least one in through-hole wall and the outer wall of solid post to be provided with Zeng Mian mechanisms.
Specifically, Zeng Mian mechanisms are any of groove, screw thread, projection or multiple.
Further, catalyst granulator also includes cutting motor and two drives；It is driven between two drives
It is connected with circular saw blade；Multistage cutting edge is uniformly provided with circular saw blade；The cutting edge of circular saw blade connects with the outer wall of cylinder casement
Touch；The rotating shaft of cutting motor is connected with any drive.
Specifically, catalyst granulator also includes motor；The rotating shaft of motor is connected with reductor in turn, passed
Moving axis；The free end of power transmission shaft is connected with pressure wheel；The output shaft of reductor is connected with the used shaft coupling of power transmission shaft.
Compared with prior art, the invention has the advantages that：Under the interaction of pressure wheel and cylinder casement,
Catalyst raw material is extruded from through hole, and the groove in through hole makes have groove on manufactured catalyst outer wall, makes it in chemistry
It is bigger with the contact area of reactant in reaction, make the time required to chemical reaction less, the catalytic effect reached is more preferable；Extrusion
Catalyst is cut off under the drive of circular saw blade, and segmentation cutting edge enables catalyst uniformly to be cut, and does not destroy its profile, makes to be made
The profile of catalyst is more attractive in appearance.
