1. Raw material storage and supply of autoclaved aerated concrete block equipment technology

　　 The raw materials fly ash or sand are transported into the factory by vehicles, and the fly ash or sand, stone powder) are concentrated in the raw material yard, and the loading hopper is used when they are used. Bagged cement or bulk cement is stored in the cement warehouse. When in use, it is used for loading and transporting into the hopper. Chemicals, aluminum powder, etc. are placed in the chemical warehouse and aluminum powder warehouse, respectively, and shipped to the production workshop when used.

　　2. Raw material processing of autoclaved aerated concrete block equipment technology

　　 Pulverized coal huiding or sand and stone powder are sent to the ball mill through an electromagnetic vibrating feeder and belt conveyor, and the ground pulverized coal huiding or sand and stone powder are sent to the slurry tank for storage respectively by a fly ash pump. The lime is sent to the jaw crusher by the electromagnetic vibrating feeder and the belt conveyor for crushing. The crushed lime is sent to the lime storage bin by the bucket elevator, and then sent to the ball mill by the screw conveyor. The screw conveyor and bucket elevator are fed into the powder batching bin. After the chemicals are manually measured in a certain proportion, a solution of a certain concentration is made and sent to the storage tank for storage. The aluminum powder is transported from the aluminum powder warehouse to the production workshop, and is lifted to the second floor of the batching building with an electric hoist, poured into a mixer, and mixed into a suspension of aluminum powder.

　　3, autoclaved aerated block concrete block equipment technology, aerated block batching, mixing, pouring

　　Lime and cement are sequentially sent to the automatic weighing scale by the screw conveyor under the powder batching bin for cumulative measurement. There is a screw conveyor under the scale to evenly add the materials into the pouring mixer.

Pulverized coal stabilization or sand, stone powder and waste slurry are put into the measuring cylinder for measurement. After the various materials are measured, the mold is in place, and the slurry can be stirred. The slurry should meet the process requirements (about 40%) before pouring. ℃). If the temperature is not enough, the slurry metering tank can be heated by steaming, and the aluminum powder suspension can be added 0.5 to 1 minute before the material is poured.

　　4. Autoclaved aerated block concrete block equipment technology for the initial curing and cutting of aerated blocks

After pouring, the mold uses a conveyor chain to advance the initial curing room for gas generation and initial setting. The room temperature is 50～70℃, and the initial curing time is 1.5-2 hours (according to the geographical advantage, this process can be avoided). After initial curing, use negative pressure The spreader hoists the mold frame and the blank body on the cutting table where the bottom plate of the kettle is placed in advance. Take off to the mold frame. The cutting machine will cross-cut, longitudinally cut the blank body, and mill the bread head, and the mold frame is hoisted back to the mold. Manual cleaning and degreasing on the car, and then hoist to the mold car for the next pouring. The cut green body and the bottom plate of the kettle are hoisted to the kettle car by a crane to stack two layers. There are four supports between the layers. Each kettle is organized into a group.

　　The waste from the edges and corners of the blank produced during cutting is sent to the waste slurry agitator next to the cutting machine by a screw conveyor, and water is added to make waste slurry, which is used for batching.

　　5. Autoclaved aerated block and finished products of autoclaved aerated block concrete block equipment technology

After the green body is assembled on the parking line in front of the autoclave, the aerated concrete opens the autoclave autoclave door to be taken out of the autoclave, first pulls out the finished autoclave car in the autoclave with a hoist, and then pulls the autoclaved autoclave car with a hoist Enter the autoclave for curing. The finished products on the kettle car are hoisted to the finished product warehouse by a bridge crane, and then transported to the finished product yard by a forklift truck. The empty kettle car and the bottom plate of the kettle are hoisted back to the carriage return line, and the stacker is pulled back by a hoist after cleaning. Go to the next cycle.

　　 Simply put, the process of aerated concrete equipment is to adopt different processes for production according to the types of raw materials, quality, and process characteristics of the main equipment. But under normal circumstances, the fly ash or silica sand is ground into a slurry with water, added with powdered Shihuidong cement, gypsum and foaming agent, and injected into the mold frame after stirring. After static oxygen foaming and solidification, cutting Blocks or plates of various specifications are sent into the autoclave by the steam-curing truck, and under the curing of high-temperature saturated steam, a porous and light-weight aerated concrete product is formed.
