Description

High performance foam rapid generator

technical field

The utility model relates to a high-performance rapid foam generator for making foam concrete products, which belongs to the field of building material manufacturing and building construction machinery.

Background technique

The high-performance rapid foam generator is a machine for producing foam concrete bricks and/or foam concrete blocks and/or foam concrete insulation layers. The foam produced by the high-performance foam rapid generator is mixed with cement paste or concrete mortar The foamed cement paste, the foamed concrete mortar body or the foamed fly ash cement paste is obtained after the powdered fly ash cement paste is evenly mixed. Foamed cement paste or foamed concrete mortar body or foamed fly ash cement paste is poured to obtain foamed concrete bricks and/or foamed concrete blocks, or foamed cement paste or foamed concrete mortar body or foamed fly ash cement paste The body is directly constructed on the top floor of the house to obtain a foam concrete heat insulation layer. The quality of foam concrete bricks and/or foam concrete blocks and/or foam concrete insulation layer is not only related to foam concrete density and foam stability, but also related to foam uniformity and cell diameter. The property and cell diameter are related to the performance of the foamer and the method of foam generation. There are four main production methods for existing foamed concrete products: the first method is to mix the solution containing the foaming agent with the concrete slurry, and then use the mixing blade of the low-speed mixer to directly inject air into the slurry for foaming. foam, and directly obtain the gas-liquid-solid three-phase foam concrete slurry. The disadvantages of this method are: ①The cell diameter of the foam changes greatly, and the pore size distribution range of the foamed concrete product is large, which reduces its strength; Slow, the production efficiency of foamed concrete products is low; ③The foaming agent cannot be fully foamed, and the utilization rate of the foaming agent is low. The second method is to mix the solution containing the foaming agent with the concrete slurry first, and then use the stirring blade of the fast mixer to directly inject air into the slurry for foaming, and directly obtain the gas-liquid-solid three-phase foam coagulation Upper body. Compared with the first method, the second method only improves the production efficiency of foamed concrete products. Because the foaming process is similar to the first method, the pore size of the obtained foam varies greatly, and the pore size distribution range of foamed concrete products Wide, the strength of foamed concrete products is reduced; the foaming agent cannot be fully foamed, resulting in a decrease in the utilization rate of the foaming agent. The third method is to first pressurize the solution containing the foaming agent to a certain pressure, and then mix, crush and foam the high-pressure water and high-pressure air in the foaming chamber in the form of a jet to obtain a foam. This method has the most advanced technology for preparing foam, high production efficiency and good effect, but due to the high operating pressure, the technical requirements for equipment are increased, the production process is complicated, the production cost is increased, and the promotion of its technology is affected. The fourth method is to first mix the liquid containing the blowing agent with compressed air through a foaming machine to obtain a gas-liquid two-phase foam, then mix the foam with the concrete slurry, and finally prepare the foamed concrete slurry. Foamed concrete products are obtained after pouring the foamed concrete slurry. Compared with the first and second types, the foamed concrete products obtained by this method are improved in terms of production efficiency and performance, but due to the difference in the internal structure of the foaming cylinder and/or the foaming cavity, the foam is entrained with The foaming agent solution that is not fully foamed reduces the utilization rate of the foaming agent; in addition, the foam diameter and distribution range of the prepared foam are quite different, which directly affects the performance of foamed concrete products.
