Embodiment 1
[0033] figure 1 with figure 2 A schematic diagram of a perforated brick mold is shown. The common width of porous bricks is 115mm, and the number of single molding is 18 pieces in 2 rows. In the porous brick forming mold, when the vibrating motor vibrates, in order to ensure that the hollow rod mounting base can vibrate accordingly, when the base is fixedly installed, a gap of 2 to 3 mm should be reserved between the base and the mounting surface of the mold frame; similarly, when When the base vibrates, in order to ensure that all the hollow rods installed on it can vibrate accordingly, a gap of 2~3mm should also be reserved between the hollow rods and the fixed base.
[0034] The autoclaved fly ash porous brick is prepared by using the above mold, which specifically includes the following steps:
[0035] (1) Prepare raw materials:
[0036] The fly ash of the power plant is pneumatically transported to the fly ash silo through pipelines for use; after the coarse slag is...

Abstract
The invention discloses a method for preparing an autoclaved fly ash porous brick, which belongs to the technical field of comprehensive utilization of metallurgical solid waste resources. The preparation method of the present invention includes four steps of (1) preparing raw materials, (2) batching, (3) forming, and (4) steaming and curing. The quality of raw materials is strictly controlled in terms of technology. Since the production process of porous bricks requires an increase in the proportion of aggregates, Therefore, the requirements for aggregates are particularly strict, and the aggregates used in the end are required to account for more than 80% of the aggregates with a particle size of 5 mm or less; at the same time, the moisture content of the mixture is strictly controlled, thereby improving the appearance quality of the molding, and the finished product is broken, collapsed, The form of damage such as missing edges and corners has been greatly improved, and the qualified rate of porous bricks has increased from 74.06% to 95%. During the molding process, by optimizing the structure of the distribution system, the blind area of the distribution can be avoided, the distribution is more uniform, and the distribution effect is improved. , improving the operating efficiency of the distributing system.
Description
technical field [0001] The invention relates to a method for preparing an autoclaved fly ash porous brick, belonging to the technical field of comprehensive utilization of metallurgical solid waste resources. Background technique [0002] The production process principle of autoclaved fly ash porous brick is basically the same as that of standard brick. The raw materials used are mainly cementing material, aggregate, and fly ash, namely quicklime, dedusting ash, coarse slag, crushed stone, and fly ash. All materials are measured according to the mixing ratio, enter the mixer, add water and mix evenly, and then send them to the digestion bin for digestion through bucket elevators and belt conveyors. After the digestion is completed, it will be fully rolled by the wheel mill. If the moisture content of the material is not suitable, water can be added to the wheel mill for a second time, and then it will be steamed in the kettle after being formed by the hydraulic brick machine...
