Stirring machine for preparing dry-mixed mortar

Abstract

The invention belongs to the technical field of stirrers, and discloses a stirrer for preparing dry-mixed mortar, which comprises a stirring barrel, an inner shell is fixedly mounted at the lower end in the stirring barrel, a stirring device is placed in the inner shell, and a motor is fixedly mounted at the top of the stirring device. A driving gear is fixedly mounted on the outer side of an output shaft at the lower end of the motor. The stirring barrel, the inner shell, the stirring device and other structures are arranged to work in a matched mode to achieve the purposes of thorough stirring, high efficiency and good effect, the stirring mode is essentially different from a traditional stirring mode, on one hand, materials are effectively mixed when spirally rising, and on the other hand, the stirring effect is greatly improved; then, a simple cycle work is formed in the structural stirring device, at the moment, the materials are vertically and secondarily stirred on the whole, the materials are more thoroughly and uniformly stirred, the dead angle and insufficient stirring condition of the materials is avoided, and the whole device is stable and simple in cooperative work, good in effect and thorough and uniform in stirring.

Description

technical field [0001] The invention belongs to the technical field of mixers, in particular to a mixer for preparing dry-mixed mortar. Background technique [0002] Dry powder mortar refers to a granular or powdery mixture of dry and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. It is transported to the construction site in the form of bags or bulk, and can be used directly after mixing with water. Also known as mortar dry powder, dry-mixed mortar, dry-mixed powder, some construction adhesives also belong to this category. Dry powder mortar plays the role of bonding, padding, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. [0003] Dry-mixed mortar is often mixed with various materials during preparation. Unlike the mixing of various fluid materials, dry-mixed mortar is often mixed with...

AI Technical Summary

Problems solved by technology

[0003] Dry-mixed mortar is often mixed with various materials during preparation. Unlike the mixing of various fluid materials, dry-mixed mortar is often mixed with materials such as large-sized particles, small-sized particles and gel, so it is doomed The mixing process of the material is not smooth, and the materials of different sizes and their hardness are completely different. In this way, the material will be stirred unevenly when stirring. The most obvious is that the porosity in the mixed material is very large. General mixing equipment In order to solve this problem, it is often to prolong the stirring time and make the structural frictional contact as thorough as possible, but this operation wastes time and is inefficient, and because there are more materials in the stirring process, the effect achieved is not very ideal.

[0004] Dry-mixed mortar is different from wet-mixed mortar. The moisture in it is very small, generally less than 0.5%, so it can have a longer shelf life. Dry-mixed mortar will be dried before mixing, but there is no way Ensure that the drying is thorough. Generally, after the mixing is completed, a second drying will be carried out, so that the material needs one more step, which is more troublesome to operate, and the traditional drying is often not thorough and uniform enough, and local The drying is serious, and the inner side is relatively less processed, which will also affect its quality

[0005] Finally, the mortar is most likely to be blocked during the mixing process, because the size of the aggregates inside is inconsistent. Although it will be sorted in advance, when several aggregates happen to be stuck to each other, this part is easy to appear at this time. Blockage, the traditional mixer lacks corresponding treatment methods, and the cost of specially arranging corresponding vibration devices is also very high, so this part of the problem has always been difficult to solve
