Embodiment 1

[0026] First prepare the fly ash slurry containing gypsum powder with a water-to-material ratio of 0.53 and add it to the pouring mixer, then prepare the lime cement slurry with a water-to-material ratio of 0.75 and add it to the pouring mixer; then add the foaming agent aluminum powder slurry and pass the heating steam into the In the casting mixer, after mixing and stirring, it takes 3 minutes to prepare a fully mixed and dispersed casting slurry. The weight ratio of raw materials: fly ash: cement: lime: gypsum = 75: 4: 16: 4; compared with the old process, the fly ash increased by 5%, the lime decreased by 5%, and the others were the same as the old process.

[0027] 190 seconds per pouring unit time. The timing arrangement is as follows: from 0 to 40 seconds, add fly ash slurry; from 5 to 45 seconds, add cement lime slurry; from 85 to 100 seconds, add foaming agent aluminum powder slurry; from 80 seconds to 140 seconds, add steam adjustment Adjust the slump by temperature...

Embodiment 2

[0034] Slurry pouring equipment adopts pouring mixer and figure 2 The calcium raw material pulping machine is composed of two parts, and the calcium raw material pulping machine is arranged above the pouring mixer.

[0035] The calcareous raw material pulping machine may use a valve 7, an agitator 12 for preparing calcareous slurry, a calcareous powder screw conveyor 13, a calcareous powder blanking port 14, and a water adding metering tank 15. Valve 7 is installed on the water inlet pipeline of adding water metering tank 15 below. The water inlet pipe mouth and the calcareous powder screw conveyor 13 are installed above the agitator 12 for preparing the calcareous slurry, and the agitator 12 for preparing the calcareous slurry is installed above the slurry addition port 5 of the calcareous raw material of the pouring mixer, and the calcium The powder feeding port 14 is arranged on the front end of the calcareous powder screw conveyor 13 .

Embodiment 3

[0040] The slurry pouring equipment consists of two parts: a pouring mixer and a calcareous raw material pulping machine, and the calcareous raw material pulping machine is arranged above the pouring mixer.

[0041] Silicon raw material: SiO 2 Tailings sand with a content of 85%, 0.08 sieve 20%-28%, water-to-material ratio 0.5; calcium raw material adopts medium-speed quicklime with CaO content of 85%, 0.08 sieve 15%-20%, 425# cement, gypsum, aluminum Powder cream.

[0042] The amount of dry materials per pouring unit: tailings sand 1800Kg, waste blocks 70-90Kg, gypsum 90Kg; lime 280Kg, cement 280Kg, aluminum powder paste 2Kg.

[0043] In the first step of the work, the tailings sand is wet ball milled into a slurry, and the water-material ratio is 0.5, which is measured according to the amount of each pouring unit; lime, gypsum, and waste blocks are ground into mixed powder according to the weight ratio, and lime, Gypsum and waste block mixed powder are made into slurry acc...

Abstract

The invention relates to a cement slurry casting and preparing method and equipment thereof, in particular to the preparation method and equipment of cement slurry which is fully blended and in dispersed solid grain status in the production of aerated concrete. The invention is characterized in that the calcium slurry solution and the silicon slurry solution are synchronously added to a casting mixer in the proportion of 2: 8-4:6 for blending, and then a foaming agent is added and mixed with the solution for 3-5 minutes. The slurry preparing and casting equipment consists of a casting mixer and a calcium slurry pulper which is arranged above the casting mixer. The produced slurry is fully mixed and shows a statue of dispersed grains, which improves the utilization of the calcium materials. The strength index can not be reduced if the calcium material is reduced by 5-10 percent based on the current proportion. The period of casting operation of each unit is shortened by 80 percent or so.

Description

technical field [0001] The invention relates to a grouting method and grouting equipment, in particular to a method for making a fully mixed and granular dispersed grout and a grouting equipment in the production of aerated concrete products. Background technique [0002] Aerated concrete products are divided into blocks, wall panels, roof panels and other products according to their functions; according to basic raw materials, they are divided into sand aerated, fly ash aerated, tailings aerated, (sand + fly ash) aerated and many other strains. They have been popularized with many advantages such as low density, light weight, heat insulation, easy processing, and waste residue utilization, especially since clay bricks were banned in building wall products. [0003] No matter what kind of air-entrained concrete products, no matter what kind of technical genre, the preparation of slurry must be the core of the process. This kind of slurry contains silicon and calcium raw ma...
