Description

Technical Field

[0001] The utility model relates to the technical field of an extrusion and pelletizing integrated machine, in particular to an extrusion and pelletizing integrated machine for forming an alumina carrier. Background Art

[0002] Alumina carrier refers to white powder or formed alumina solid. It is the most widely used catalyst carrier, accounting for about 70% of industrial supported catalysts. Alumina has many forms. Not only do different forms have different properties, but even the same form has different properties due to its different sources. When alumina is used in, it needs to be made into granules, so a granulator is needed for processing.

[0003] The current integrated pelletizing machine is usually composed of a frame, a motor, a rotating shaft, a transmission device, an extrusion device and a cutting device. When working, the rotating shaft is driven by the motor, and then the rotating shaft rotates through the transmission device and the cutter. At the same time, the transmission device drives the extrusion device to extrude the raw material into strips, and then the strips are cut by the cutter. However, the existing cutters are usually directly fixed on the outside of the rotating shaft, and the rotating shaft drives the cutter to rotate, and then the strips are cut into particles. When the cutter cuts symmetrical strips, one end of the cutter is suspended in the air, which causes the cutter to swing up and down easily when it moves, resulting in the cut particles being not uniform, thereby affecting the granulation quality. Therefore, the inventor proposes an extrusion and pelletizing machine for alumina carrier molding to solve the above problems. Utility Model Content
