Description

Technical Field

[0001] The utility model relates to the technical field of low-carbon gelling material production, in particular to a screw conveying device used for low-carbon gelling material production. Background Art

[0002] Low-carbon cementitious materials are a new, environmentally friendly building material designed to replace traditional Portland cement, reducing energy consumption and carbon emissions. Low-carbon cementitious materials can be made from a variety of industrial solid wastes, such as tailings, slag, steel slag, desulfurized gypsum, and fly ash. These raw materials undergo mechanical processing, such as crushing to an average particle size of less than 3μm, to distort the surface lattice of the material. The materials are then chemically activated using an activator to produce the low-carbon cementitious materials, which are then transported and transferred using conveying devices.

[0003] Existing conveying devices can only transport raw materials and cannot assist in subsequent production processes, which often affects production efficiency. During production, multiple raw materials usually need to be mixed, which requires the assistance of multiple raw material conveying channels.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a screw conveying device for the production of low-carbon cementitious materials is proposed, in order to achieve a more practical purpose. Utility Model Content

[0013] Furthermore, the driving motor forms a transmission structure through the transmission rod and the auger blades.

[0014] The utility model provides a screw conveying device for producing low-carbon cementitious materials, which has the following beneficial effects:

[0015] 1. This utility model uses auger blades and transmission rods as the transmission structure, places low-carbon gelled raw materials inside the conveying cylinder for stirring and mixing, and uses the discharge pipe provided at the end of the conveying cylinder to receive the mixed materials discharged from the discharge pipe by the output belt, which is convenient for transportation and transfer;
