A cutting device and material production device for catalyst

Abstract

The invention discloses a cutting device and a material production device and belongs to the field of material processing. The cutting device comprises a power device, a transmission mechanism and a cutting tool; the cutting tool comprises a fixed blade and a movable blade which are installed at the conveyor belt output end of a transmission device; the fixed blade can make contact with materialsconveyed on a conveyor belt, and the movable blade is connected with the transmission mechanism and comprises a plurality of blade units which are arranged in a line at intervals, wherein an intervalexists between the cutting edge end of each blade unit and the conveyor belt; the power device drives the transmission mechanism to move and drives the movable blade to make reciprocating linear movement relative to the fixed blade in the direction perpendicular to the conveyor belt; and relative movement between the fixed blade and the movable blade from shearing force to transversely cut the materials. According to the cutting device, the conveyor belt can be prevented from being damaged, deformation of cut particles is reduced, and uniformity and regularity of material particles are effectively ensured.

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
