Production device and production method of microporous lightweight building material

Abstract

The invention discloses a production device of micropore lightweight building materials. The production device of the micropore lightweight building materials comprises an inner pipe, wherein the front end of the inner pipe is connected with a storage tank filled with slurry by a concrete conveying pipe; the concrete conveying pipe is provided with a concrete conveying pump; the rear end of the inner pipe is connected with a micropore lightweight building material conveying pipeline; the inner diameter of each of the concrete conveying pipe and the inner pipe is 3-10 times the diameter of the biggest particle in slurry; the inner pipe is sleeved with a jacket; a high-pressure air cavity is formed between the inner pipe and the jacket, and is connected with cement paste outside the jacket by a gas intake pipe which is provided with a flow meter; the inner pipe is provided with a plurality of air inlets; the total area of the air inlets is not greater than 20% of the external surface area of the inner pipe; each air inlet is provided with a spray nozzle facing the inner cavity of the inner pipe. The production device disclosed by the invention is simple in structure, few used devices are used, foaming cylinders are omitted, the building materials can be directly produced in a pipeline without foaming in advance, the production cost is low, and on-site operation is realized.

Description

technical field [0001] The invention relates to a construction engineering production device, in particular to a production device for producing microporous lightweight building materials in a pumping pipeline, and also relates to a production method of the microporous lightweight building materials. Background technique [0002] Microporous lightweight building materials mainly include foam mixed lightweight soil, foamed cement or microporous lightweight concrete. In the prior art, the preparation process for producing microporous lightweight building materials is complex and requires a lot of equipment. The common process is as follows: the foaming agent is transported to the foaming machine through a water pump, and air is input into the foaming machine through an air pump at the same time. Bubbles are formed and added to the mixer, and the soil and cementitious materials are added to the mixer, and the required microporous lightweight building material can be obtained af...
