Description

Technical Field

[0001] This invention relates to the field of lightweight aggregate concrete technology, and in particular to a lightweight aggregate dry-mixed mortar production system and process. Background Technology

[0002] Lightweight aggregate concrete refers to concrete with a dry apparent density of no more than 1950 kg / m³, made by using natural porous lightweight aggregate or artificial ceramsite as coarse aggregate, natural sand or lightweight sand as fine aggregate, and silicate cement, water and admixtures according to the mix proportion requirements. Lightweight aggregate is a special aggregate selected to reduce the weight of concrete and improve thermal performance.

[0003] According to application number CN202011017047.0, a lightweight aggregate, its preparation method, and concrete using the lightweight aggregate are disclosed. The lightweight aggregate includes fiberglass particles, a silane coupling agent, and cement slurry. The cement slurry is prepared from cement, silica fume, hollow glass microspheres, an early-strength agent, and water. The preparation method is as follows: a diluent for the silane coupling agent is prepared, the pH of the diluent is adjusted, the silane coupling agent is added and ultrasonically mixed, fiberglass particles are added and stirred, after stirring, the fiberglass particles are removed, washed with anhydrous ethanol, and dried to obtain surface-modified fiberglass particles; cement slurry is prepared, the cement slurry is sprayed onto the surface-modified fiberglass particles and dried to obtain the lightweight aggregate.

[0015] Beneficial effects

[0016] This invention achieves the screening of lightweight aggregates through the setting of a screening mechanism. By rotating the operating wheel, the operating wheel drives the worm to rotate. The rotation of the worm, through the meshing of the worm and worm wheel, drives the double-ended screw to rotate. Through the meshing of the double-ended screw and threaded blocks, the two threaded blocks slide in opposite directions when the double-ended screw rotates. The sliding of the threaded blocks drives the operation of a scissor mechanism composed of multiple first and second hinged rods. The operation of the scissor mechanism drives the screening inclined rods to slide. By adjusting the distance between adjacent screening inclined rods, lightweight aggregates of different sizes can be screened. The appropriate lightweight aggregates located at the upper end of the screening inclined rods pass through the gaps between adjacent screening inclined rods and fall onto the conveying equipment. After being conveyed, they are transported into the mixing equipment. This prevents larger pieces of lightweight aggregates from entering the mixing equipment and affecting the quality of lightweight aggregate concrete, thereby improving production quality and reducing economic losses.

[0017] Furthermore, the material distribution mechanism effectively removes large pieces of lightweight aggregate. As the screening bar slides, it drives the lower end of the flexible component to slide via an adjusting groove. When the distribution motor starts, it drives the transmission chain via a fixed sprocket. This transmission chain then moves the fixed block via a plate component. The displacement of the fixed block, in turn, drives the flexible component via a sliding block. During this process, the flexible component gradually adjusts to align with the adjusting groove. At this point, the flexible component delivers the unqualified lightweight aggregate from the upper end of the screening bar, allowing it to fall onto the surface of the receiving inclined plate. The aggregate is then discharged through the discharge component via the receiving inclined plate. This eliminates the need for manual operation, reducing workload, increasing efficiency, and lowering labor intensity.

[0018] In addition, the vibration mechanism enables the lightweight aggregate to vibrate during screening. The vibration motor drives the vibration cam to rotate via the fixed shaft, causing the hopper to vibrate and preventing blockage of the lightweight aggregate in the hopper, thus improving work efficiency.

[0019] Furthermore, the aforementioned mechanism enables the screening of lightweight aggregates, improving production quality and reducing economic losses. It also enables the removal of large pieces of lightweight aggregates, improving work efficiency and reducing labor intensity. Additionally, it allows for the vibration of lightweight aggregates during screening, preventing blockage in the hopper and further enhancing work efficiency. Attached Figure Description

5. The production process of the lightweight aggregate dry-mixed mortar production system as described in claim 1 includes the following steps: Materials preparation: (1) Lightweight aggregate: Select appropriate lightweight aggregates, such as expanded perlite, expanded vermiculite, expanded polystyrene, etc. Determine the type of aggregate according to the needs of use. The specific gravity of lightweight aggregates should be less than that of ordinary concrete aggregates to ensure the lightweight characteristics of concrete. (2) Cement: Cement is the cementing material for lightweight aggregate concrete. Cement with stable quality and strength grade should be selected. Commonly used cements include silicate cement and ordinary silicate cement. (3) Admixtures: Admixtures can improve the performance of lightweight aggregate concrete, such as water-reducing agents, air-entraining agents, and early-strength agents; Mixing ratio: The mix proportion is crucial for ensuring the performance of lightweight aggregate concrete. The water-cement ratio and aggregate ratio are determined according to the specific requirements of the building. The mix proportion for high-strength lightweight aggregate concrete is cement:fine aggregate:coarse aggregate:water = 1:2-3:3-4:0.4-0.5; the mix proportion for low-strength lightweight aggregate concrete is cement:water:lightweight aggregate = 1:0.4-0.5:6-8; and the mix proportion for lightweight aggregate concrete for pressure pipelines is cement:water:lightweight aggregate = 1:5:0.

38. Material mixing: According to the determined proportions, add the prepared cement, lightweight aggregate, mortar, and admixtures to the dry mixer and mix them, ensuring that the mixing time is 3-5 minutes. Packaging and shipping: The mixed lightweight aggregate concrete is loaded into woven bags, sealed with a sealing machine, and then placed into a conveyor belt for transport.
