Description

Technical Field

[0001] The utility model relates to the technical field of catalyst particle carrier production, in particular to a catalyst particle carrier preparation device. Background Art

[0002] Catalysis is an important process in petroleum refining or chemical synthesis. In order to improve catalytic efficiency, the catalyst is usually adsorbed onto a particle carrier with a certain geometric shape. There are various forms of devices for manufacturing catalyst particle carriers in the existing technology. Among them, hydration rolling balls, pulping granulation, oil-ammonia column drop devices and other devices produce spherical catalyst particle carriers, and extrusion devices produce columnar catalyst carriers with different axial cross-sections. The granules are then artificially broken into particles after drying.

[0003] The existing catalyst particle carrier preparation device (its authorization announcement number is: CN 2928438Y) is a device that can continuously and simultaneously cut and granulate the cylindrical paste material after the discharge die of the extruder extrude the cylindrical paste material. The multiple circular blades on the two rotating cutter shafts cooperate to improve the production efficiency of granulation. The cut paste particle carrier naturally falls into an open container. After accumulating to a certain amount, the paste particle carrier is sent to an oven to be dried into a solid catalyst particle carrier.

[0004] However, this type of catalyst particle carrier preparation device has some shortcomings during actual use: since the knife shaft is located below the cylindrical paste blank, the cylindrical paste blank after cutting naturally falls onto the knife shaft, which easily causes the cylindrical paste blank to be cut twice after cutting, and then causes the final cylindrical paste blank to be inconsistent in size, affecting the quality of the finished catalyst particle carrier; therefore, we proposed the utility model to solve the above problems.
