Description

Technical Field

[0001] The invention belongs to the technical field of autoclaved aerated block production, and in particular relates to an autoclaved aerated block which is easy to splice, and further relates to a production process of the autoclaved aerated block which is easy to splice. Background Art

[0002] Autoclaved aerated block is a new type of wall material with light weight and closed micropores, which is made of fly ash, lime, gypsum as main raw materials, and mixed with appropriate amount of gas generating agent, and is made by pouring, stopping, cutting, high temperature and autoclaving. It has the characteristics of light weight, good thermal insulation, heat insulation, waterproof, sound absorption, earthquake resistance, and convenient on-site construction. It is mainly suitable for filling walls of frame and high-rise buildings; non-load-bearing partition walls; composite insulation layer and self-insulating exterior wall of energy-saving buildings; roof insulation layer, etc. It is a new type of energy-saving wall material widely used at home and abroad.

[0003] When assembling the autoclaved aerated blocks in the prior art, the finished blocks have a simple structure and are relatively convenient to splice, especially at corners, where grooves and protrusions are directly plugged in, resulting in poor stability and consistency of the splicing at the corners. Pulling at the connection can easily lead to the risk of cracking, poor durability, and the stability and aesthetics of the joints need to be improved. At present, when preparing autoclaved aerated blocks, workers have to operate many procedures, which is not convenient for automation and can reduce the positive output of labor.

[0018] A production process of autoclaved aerated blocks that are easy to splice, specifically comprising the following steps:

[0019] S1. Preparation of raw materials: First, add sand into the three-bin hopper, then convey it to the ball mill for grinding via a belt conveyor. The density of the ground slurry is measured and fed back in real time via the density pipeline system. The slurry with precise density is directly pumped into the slurry tank for storage.

[0020] S2. Preparation of steel mesh cage: the coiled steel bar is processed by a fully automatic mesh welding machine, the mesh welding is completed at one time, and the mesh cage is prepared by a hanging welding machine, and the mesh cage is assembled with a circulation frame. The assembled mesh cage frame is transferred to the anti-corrosion carriage by a shuttle bus, and the rust removal and anti-corrosion of the mesh cage are completed by an overall immersion paint method, and then it is transferred to a drying room for drying. The dried mesh cage frame is placed on the automatic circulation walkway by a transfer carriage for standby use;

[0021] S3, batching and pouring: the accurately measured materials are automatically formulated and fully mixed under the high-speed stirring of the pouring mixer. After the slurry is poured into the mold box, the bubbles are sorted. The poured mold box is operated by the pouring shuttle car, and then conveyed to the insertion and extraction position by the friction wheel. The prepared mesh cage is placed in the mold box to complete the insertion;

[0022] S4, curing, turning and cutting: the mold box poured and inserted in step S3 is put into the curing room, and the mold box is transferred to the empty mold box position by a high-speed curing shuttle bus. The embryo body is cured through the three processes of gasification, initial setting and hardening;

[0023] When producing panels, the embryo body first goes through the process of pulling out the steel pins and the frame from the mold after leaving the resting room. The unloaded frame returns together with the saddle frame, and the mold moves to the demoulding position. The embryo body is demoulded by the flip demoulding machine and accurately placed on the positioning cone pin of the cutting trolley. The flip demoulding machine re-closes the empty mold box and the side plate. After closing the mold, the mold box returns to the casting position to continue casting.

[0024] The embryo is first cut sideways, then cut horizontally by a horizontal cutter, and then cut into the required autoclaved aerated blocks by a cross cutter;

[0025] S5, curing in the autoclave: the embryos are transferred to the steam curing trolley by a marshaling vehicle, and then transferred to the pre-curing room by the shuttle bus in front of the autoclave. The tractor then tows the steam curing trolley to the pre-curing room to wait for entering the autoclave. After entering the autoclave, steam curing begins. During the steam curing process, the autoclave is supplied with steam by the fully automatic steam curing equipment.

[0026] S6. Packaging of finished products out of the autoclave: After steam curing, the autoclave is first vented and depressurized, and then the steam curing trolley is pulled out by the autoclave traction shuttle car and transferred to the return track. It is then transported to the unloading position by the traction machine. The finished product handling crane sends the single-mold embryo body to the side plate return system, and the side plate return system sends the embryo body to the splitter for splitting. After that, the side plate return system continues to transport the embryo body to the finished product clamping machine. The clamping machine transports the finished product into blocks and stacks them onto the conveyor chain, moves to the rotating clamp, completes the packaging process, and is then taken off the production line by the clamping machine and forklift.

[0027] Preferably, the material formula in step S3 includes the following raw materials in weight percentage: 30-35 parts of sand, 30-35 parts of fly ash, 10-15 parts of cement, 3-5 parts of magnesium carbonate, 11-13 parts of coconut shells, 35 parts of aerated aluminum powder, 11-13 parts of ceramic fiber, 7-9 parts of quicklime, 0.3-0.5 parts of sulfur powder and an appropriate amount of water.

[0028] Preferably, in step S1, the fineness of the sand is 0.08 mm, and the residue on the square hole sieve is less than 15%.

[0029] Preferably, the inserting process in step S3 uses a steel drill, and the steel drill uses a wax coating process instead of a traditional oil coating process.

[0030] The technical effects and advantages of the present invention are as follows: the autoclaved aerated block and its production process which are easy to splice, propose that the second corner block and the first corner block are connected by mortise and tenon to form a corner autoclaved aerated block, and the second corner block and the first corner block are connected by convex tenon and concave tenon and tenon, the overall consistency is greatly improved, the risk of cracking caused by pulling at the connection is reduced, and the block is strong and durable, with high firmness and strength. In addition, the first aerated block, the second aerated block, the third aerated block and the fourth aerated block which are connected with the second corner block and the first corner block to form a wall panel are proposed. When two adjacent groups of autoclaved aerated blocks are spliced, the second rectangular protrusion is inserted into the inner side of the second rectangular groove, and the first right-angle notch is butted with the second right-angle notch, which is convenient for assembly, and the first right-angle notch and the second right-angle notch are butted to form a U-shaped opening groove, which is convenient for adding a reinforcement plate later to improve the stability and aesthetics of the joint.

[0031] The production of autoclaved aerated blocks involves six processes: preparation of raw materials, preparation of steel mesh cages, pouring of ingredients, resting, turning and cutting, maintenance in the autoclave, and packaging of finished products. Except for the manual assembly of the mesh cages and the circulation frame in the preparation of the steel mesh cages, the entire production line adopts an automated production line, which greatly improves the processing efficiency and preparation efficiency, and reduces labor costs.
