Preparation process of air-entrained blocks and storage of materials
The raw materials of air-entrained blocks, fly ash, sand, stone powder, etc., are transported to the processing workshop by unified special vehicles in the raw material factory. The cement chemicals, aluminum powder, etc. required for the production of air-entrained blocks are stored separately. In a suitable storage space, it can be transported directly to the workshop when needed.
Raw material preparation process for aerated block production
The lime is sent to the jaw crusher for crushing through the electromagnetic vibrating feeder and belt conveyor. The crushed lime is sent to the lime storage bin through the bucket elevator. Then it is sent to the ball mill through the screw conveyor, and the ground material is sent into the powder batching bin through the screw conveyor bucket elevator. The stone powder is sent to the ball mill through the electromagnetic vibrating feeder fly ash or sand belt conveyor, and the finely ground fly ash or sand powder is sent to the slurry tank for storage using a fly ash pump. Add the proportion of aluminum powder and water to the mixer and stir until an aluminum powder suspension is formed.
Ingredients mixing and pouring procedures for air-entrained blocks
Add pre-measured lime and cement ingredients into the mixer, put fly ash or sand and gravel powder waste slurry into the measuring cylinder for measurement, and after measuring various materials, the mold When it is in place, the slurry can be stirred. The slurry should reach the process requirements of about ℃ before pouring. If the temperature is not enough, steam can be heated in the slurry metering tank, and the aluminum powder suspension can be added 10 minutes before the material is poured. .
Initial curing and cutting procedures for air-entrained blocks
After pouring, the mold is pushed into the initial curing chamber with a conveyor chain for gas generation and initial condensation. The room temperature is ℃ and the initial curing time is longer. Depending on the favorable geographical conditions, it is not necessary to go there. After the initial cultivation of this process, a negative pressure hoist is used to lift the mold frame and the blank together to the cutting table where the bottom plate of the kettle has been placed in advance. It is manually cleaned and degreased on the mold transport truck, and then lifted to the mold truck to assemble the mold for the next pouring. The cut green body, together with the bottom plate of the kettle, is hoisted to the kettle car with a crane and stacked in two layers. There are four layers between the layers. Support, how many cauldron cars are grouped into a group. The corner waste of the green body produced during cutting is sent to the waste slurry mixer next to the cutting machine via a screw conveyor, and water is added to make waste slurry, which can be used when batching.
Finished products and steamed blocks of air-entrained blocks
After the green bodies are assembled on the parking line in front of the kettle, the air-entrained concrete opens the door of the autoclave to be discharged from the kettle, and first uses a winch to pull out the kettle. The finished product kettle cart is placed inside, and then the kettle cart to be autoclaved is pulled into the autoclave by a winch for maintenance. The finished products on the kettle car are lifted 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 return line. After sorting, the pallet rack is pulled back by a winch. to hold the next cycle.
To put it simply, the aerated concrete installation process is to adopt different processes for production based on the type, quality, and important installation process characteristics of the raw materials. But under normal circumstances, fly ash or silica sand is ground into a slurry with water, and an appropriate amount of cement gypsum and foaming agent are added. After stirring, it is injected into the mold frame. After static oxygen foaming and solidification, it is cut. Blocks or plates of various specifications are sent into the autoclave by a steam-curing truck, and under high-temperature saturated steam curing, porous lightweight aerated concrete products are formed.
