Foamed concrete stirring device

Abstract

The invention relates to the technical field of building materials, and particularly discloses a foamed concrete stirring device which comprises a stirring barrel, a stirring mechanism and a driving portion. The stirring mechanism comprises a stirring shaft, stirring blades are fixed on the stirring shaft, a water flow passage is arranged in the stirring shaft, the upper end of the stirring shaftis connected with a water pump communicated with the water flow passage while the lower end of the same is communicated with the bottom of the stirring barrel, a throat portion is arranged in the middle of the water flow passage, an air incoming pipe is fixed on the periphery of the stirring shaft, and the lower end of the air incoming pipe is communicated with the throat portion while the upper end of the same extends out from the top of the stirring barrel; the driving portion drives the stirring barrel and the stirring shaft to rotate in opposite directions, the stirring barrel comprises anupper section and a lower section, the lower section of the stirring barrel is cylindrical while the upper end of the same is in the shape of a cone with a small end up, and spiral guide pieces are fixed on the inner wall of the lower section of the stirring barrel. The foamed concrete stirring device can inhale air and foam concrete when stirring the concrete.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a foamed concrete mixing device. Background technique [0002] Foam concrete is a foaming agent that is introduced into the cementitious material, fine aggregate, and water system, and produces tiny airtight uniform bubbles inside the concrete through physical or chemical foaming methods, forming a kind of foam with good light weight, heat preservation, and insulation. Concrete material with heat resistance, sound insulation and frost resistance. Due to the excellent properties of foamed concrete, the research and development of foamed concrete are paid great attention at home and abroad. With the further deepening of foamed concrete research and the continuous improvement of preparation technology, the application prospect of foamed concrete will become better and better. [0003] In the commonly used methods, the foaming agent aqueous solution is generally prepared ...

Problems solved by technology

But the foaming operation of these methods all adopts foaming agent to foam, and the foaming agent price of good quality is generally on the high side, makes the preparation cost of foamed concrete increase, is unfavorable for the large-scale popularization of foamed concrete, and the foaming agent of poor quality The bubbles produced by the foaming agent have different sizes and poor stability, which affects the preparation of foamed concrete
