A material production device

Abstract

The invention discloses a material production device with an extrusion molding discharge correction device, which belongs to the field of material processing. The correction device includes a power device and a transmission device. The transmission device includes a transmission shaft and a driving roller fixedly connected to the driving shaft. The driving roller includes a roller in the middle and two side walls fixedly connected to both ends of the roller and arranged in parallel. The rollers An annular recessed portion distributed along the radial direction of the roller is formed between the outer wall of the barrel and the inner walls of the two side walls. The recessed portion is located in front of the discharge port of the extrusion device. A transmission device is provided directly below the roller; for power device It drives the transmission shaft to rotate and drives the driving roller to rotate, so that the material extruded from the discharge port moves smoothly through the depression in the forward direction. The correction device of the present invention has a simple structure and is easy to operate. It can correct the discharging direction and adjust the discharging speed to ensure uniform discharging speed, regularize the material arrangement direction, facilitate subsequent cutting, and effectively improve the uniformity and regularity of material particles.

Description

Technical field [0001] The invention belongs to the field of material processing, and relates to a material production device with an extrusion molding discharging straightening device. Background technique [0002] Catalyst materials are widely used in chemical production, scientist 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 type of reaction, it can be divided into polymerization, polycondensation, esterification, acetalization, hydrogenation, dehydrogenation, oxidation, reduction, alkylation, isomerization, etc. catalyst. [0003] The molding process of the catalyst has an important influence on the macrostructure and microstructure of the catalyst (specific surface area, pore volume, and most likely pore size, etc.), and the structure of the catalyst can determine the distribution of its active components and the activity and selection during the reaction.

AI Technical Summary

Problems solved by technology

The current extrusion molding equipment generally adopts a twin-screw extruder. The existing twin-screw extruder has uneven speed of the catalyst material at the discharge port due to the uneven screw speed, resulting in the problem of horizontal movement, which causes the problem of The arrangement direction of the catalyst is disorderly, which is not convenient for subsequent cutting. The shape of the cut catalyst particles is irregular and the uniformity is poor, which eventually leads to the failure of the catalyst to be used in the tube-and-tube reactor.
