A cutting device and material production device for catalyst

Abstract

The invention discloses a cutting device and a material production device for a catalyst, which belong to the field of material processing. The cutting device includes a power unit, a transmission mechanism and a cutter. The cutter includes a fixed blade and a movable blade installed at the output end of the conveyor belt of the conveyor. The fixed blade can be in contact with the materials transported on the conveyor belt. The movable blade is connected to the transmission mechanism. The movable blade includes a A row of multi-segment blade units arranged at intervals, with a gap between the blade end of each blade unit and the conveyor belt; the power device drives the transmission mechanism to move, and drives the moving blade relative to the fixed blade in a direction perpendicular to the conveyor belt It performs reciprocating linear motion, and the relative motion between the fixed blade and the movable blade forms a shearing force to cut the material laterally. The cutting device for catalysts of the present invention can avoid damage to the conveyor belt, reduce deformation of the cutting particles, and effectively ensure the uniformity and regularity of the material particles.

Description

technical field [0001] The invention belongs to the field of material processing, and relates to a cutting device for catalysts and a material production device with the cutting device. Background technique [0002] Catalyst materials are widely used in chemical production, scientists' experiments and life activities. There are many types, which can be divided into liquid catalyst and solid catalyst according to the state; according to the reaction type, it can be divided into polymerization, polycondensation, esterification, acetalization, hydrogenation, dehydrogenation, oxidation, reduction, alkylation, isomerization, etc. catalyst. [0003] The common catalyst production process is generally as follows: mixing → extrusion molding → drying → pelletizing. At present, the existing rotary knife or steel wire pelletizing method is to directly use a rotary blade or a rotary steel wire to pelletize the catalyst at the discharge port of the extrusion device. During the cutting ...

AI Technical Summary

Problems solved by technology

At present, the existing rotary knife or steel wire pelletizing method is to directly use a rotary blade or a rotary steel wire to pelletize the catalyst at the discharge port of the extrusion device. During the cutting process, the catalyst sags significantly due to the effect of gravity, and the deformation of pelletizing is large. , poor uniformity

However, the existing cross-cut straight-knife granulation method uses a straight knife to directly cut the material on the conveyor belt from top to bottom along the vertical direction perpendicular to the conveyor belt. Although it can improve the uniformity of granulation, it is easy to damage the conveyor belt and increase Cost of production
