Description

Technical Field

[0001] The utility model relates to the technical field of concrete production and feeding, in particular to a lightweight aggregate concrete production and feeding device. Background Art

[0002] Lightweight aggregate concrete, also known as Light Weight Concrete (LC), is a structural concrete made of light coarse aggregate (such as ceramsite), ordinary sand, cement and water. Its strength grade ranges from LC15 to LC60. The characteristics of light aggregate concrete include light weight, high strength, thermal insulation, earthquake resistance and anti-seepage. Compared with ordinary concrete of the same grade, light aggregate concrete can reduce its own weight by more than 20 to 30%. In addition, light aggregate concrete also has good thermal insulation and sound insulation effects, which helps to save material, transportation and labor costs.

Specifically, it is a lightweight aggregate concrete production feeding device for construction, including three groups of storage barrels, which are fixedly connected by equipment connecting rods, and both ends of the equipment connecting rods are fixedly connected with support frames; the utility model uses a pushing mechanism to allow the expanded clay, sand and cement powder raw materials of lightweight aggregate concrete to be mixed in advance before being fed into the interior of the building mixing barrel, thereby shortening the mixing time of the lightweight aggregate concrete raw materials in the building mixing barrel, improving the production efficiency of lightweight aggregate concrete, and suppressing the flying of dust on the construction site through the dust suppression mechanism.
