Description

Technical Field

[0001] The utility model relates to the technical field of silo feeding, in particular to an automatic silo feeding device for a production line for prefabricating active powder concrete components. Background Art

[0002] Reactive powder concrete (RPC) is a high-strength, highly durable material widely used in construction and engineering. The silo loading process in precast production lines is a crucial step in the production of RPC components. The silo loading process involves ensuring that the silo, mixer, conveyor belt, and other equipment are in good condition. The work area is clean and clear of debris that could disrupt production. The required RPC raw materials, such as cement, fine aggregate, water, and admixtures, are prepared. The silo and mixer control systems are then activated to ensure proper operation. Prior to loading, the raw materials are quality-tested to ensure they meet production requirements and are evenly mixed in the silo to avoid stratification or clumping.

[0003] Currently, reactive powder concrete component prefabrication plants require a small reactive powder concrete mixing station, which, along with an automatic material placement device and a vibration platform, forms a production line for reactive powder concrete components. Due to the high silo top, raw materials are typically stored in ton bags. Forklifts are used to transport the materials to the silo top, and then workers stand on the silo roof to cut the bottom of the ton bags to unload the material. The silo top cover must be opened to allow the bagged sand and gravel powder to be poured into the silo after the cuts are made. This creates significant dust, poses a high safety risk to workers working on the silo top, and is time-consuming and labor-intensive. Utility Model Content
