Lightweight aggregate cement concrete mixing device and mixing method thereof

Abstract

The invention relates to a lightweight aggregate cement concrete mixing device. The lightweight aggregate cement concrete mixing device comprises a cement charging mechanism, a cement slurrying mechanism and a lightweight aggregate mixing mechanism which are sequentially connected, and the stirring speeds of the cement slurrying mechanism and the lightweight aggregate mixing mechanism are gradually reduced. The lightweight aggregate cement concrete mixing device further comprises a concrete continuous mixing mechanism connected with the lightweight aggregate mixing mechanism. The mixing speed of the concrete continuous mixing mechanism is lower than that of the lightweight aggregate mixing mechanism. The lightweight aggregate cement concrete mixing device overcomes the defects that a single type stirring machine is adopted in existing lightweight aggregate cement concrete mixing equipment, and consequently cement caking, lightweight aggregate crushing and uneven cement mixing are likely to be caused, and the lightweight aggregate cement concrete mixing device has the beneficial effects that the cement is not caked, the lightweight aggregate is not crushed, and the lightweight aggregate and the cement are evenly mixed.

Description

technical field [0001] The invention relates to a light aggregate cement concrete mixing device and a mixing method. Background technique [0002] With the development of construction technology, the application of various types of lightweight aggregate cement concrete is becoming more and more extensive. However, the existing light-aggregate cement concrete mixing equipment mostly uses a single mixer, which is not only difficult to fully complete the flocculation and mixing process of the cement, but also because the light-aggregate cement concrete uses fine aggregates and lacks hard coarse aggregates. The process cannot fully complete the uniform mixing of the cement slurry and the light aggregate. Therefore, a light-weight aggregate cement concrete mixing device is provided, which is composed of a combination of various types of devices with different mixing and mixing speeds, which can not agglomerate the cement during the mixing process and after the preparation is com...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of existing lightweight aggregate cement concrete mixing equipment that adopting a single type of mixer is easy to cause cement agglomeration, light aggregate breakage and uneven mixing with cement, the present invention provides a combination of multiple types of mixing devices and mixing The lightweight aggregate cement concrete mixing device and its mixing method whose speed decreases and changes in turn, has the advantages of making the cement not agglomerated, the lightweight aggregate not broken, and the lightweight aggregate and cement mixed uniformly
