A high-efficiency aggregate saturated surface dry mixing device

Abstract

The invention discloses a high-efficiency aggregate saturated surface dry mixing device, which comprises a box body, a cavity arranged in the box body, and mixing drums symmetrically arranged in the box body. The heating component, the two sets of mixing drums are equipped with stirring rollers, and the stirring rollers are equipped with an air outlet component for blowing the surface of the aggregate. There are a number of stirring blades arranged in a ring on the side wall of the stirring rollers, and the rotating shaft of the stirring blades runs through the The side wall of the stirring roller is fixed with a bevel gear 1, and a worm wheel ring is installed for rotation in the cavity. , There is a double-axis motor fixed in the cavity, which can evenly stir the aggregate and at the same time quickly dry the moisture on the surface of the aggregate, speed up the evaporation of moisture on the surface of the aggregate, and reduce the working intensity of the staff.

Description

technical field [0001] The invention relates to the technical field of stirring equipment, in particular to a dry stirring device for high-efficiency aggregate saturated surface. Background technique [0002] Aggregate is also called aggregate. Aggregates are divided into coarse aggregates and fine aggregates. One of the main components of concrete. It mainly acts as a skeleton and reduces the volume change caused by the shrinkage and swelling of the cementitious material during the coagulation and hardening process, and also acts as an inexpensive filler for the cementitious material. There are natural aggregates and artificial aggregates, the former such as crushed stone, pebbles, pumice, natural sand, etc.; the latter such as cinder, slag, ceramsite, expanded perlite, etc. The aggregate with an apparent particle density of less than 1700 kg / m3 is called light aggregate, which is used to make ordinary concrete; especially heavy aggregate is used to make heavy concrete, ...

AI Technical Summary

Problems solved by technology

[0003] Traditional aggregates are usually blown into warm air with a hand-held hair dryer by the staff, and the samples are constantly stirred, so that the moisture on the surface of the aggregates can be evenly evaporated in all parts, and the estimated saturated surface dry state is reached. During this process, the staff needs to keep turning Mixing and blowing for more than one hour will increase the working intensity of the staff, and at the same time, uneven mixing and blowing will occur, which will affect the evaporation of water on the surface of the aggregate, so there is room for improvement
