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.

Embodiment approach

[0031] Such as figure 1 with figure 2 As shown, this preferred embodiment proposes a material production device, which includes an extrusion device 1, a discharge straightening device 2, a conveying device 3, a cutting device 4, and a drying device. The extrusion device 1 adopts a twin-screw extruder, which is used for extruding and molding the material 13. The discharging straightening device 2 is arranged at the extruding outlet 5 of the twin-screw extruder, and is used to straighten the discharging direction of the twin-screw extruder and adjust the discharging speed to be uniform. The conveying device can convey the extruded catalyst material 13 to the cutting device 4 for pelletizing operation. The cutting device 4 is arranged at the end of the entire production device and at the end of the conveying device for cutting the extruded catalyst material strips into pellets. The drying device will dry the cut material particles to remove the moisture contained in the final p...

Abstract

The invention discloses a discharging correcting apparatus for extrusion moulding and a material production apparatus, and belongs to the field of material processing. The correcting apparatus includes a power apparatus and a transmission apparatus. The transmission apparatus includes a transmission shaft and a drive roller in fixed connection to the transmission shaft, wherein the drive roller comprises a central roller and two side walls, which are in fixed connected to two ends of the roller and are in parallel. Annular concave parts are in radial distribution along the roller, are formed between outer walls of the roller and inner walls of the two side walls, and are located in front of a discharge port of an extrusion device. A conveyer is located right below the roller. The power apparatus is used for driving the transmission shaft to rotate, driving the drive roller to rotate, and making the material which is extruded from the discharge port pass through the concave parts in a forward direction and perform stable movement. The correcting apparatus is simple in structure and easy to operate, can correct the discharging direction, adjusts the discharging speed so as to make the discharging speed uniform, and regulates the arrangement direction of the material, which is convenient for following cutting. Therefore, the uniformity and discharging speed of material particles can be efficiently improved.

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. Sex and ...
