Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a quantitative feeding device for concrete waterproofing agent. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is typically made by mixing six main components—cement, water, admixtures, additives, and sand and stone aggregates—in a specific ratio, followed by uniform mixing, compaction, and curing to form an artificial stone material. Admixtures are the core raw material of modern concrete, improving its mechanical, durability, and workability. Concrete waterproofing agents are a major type of admixture, primarily used to enhance the waterproofing and impermeability of concrete, achieving a waterproofing grade of P25 or higher.

[0003] Concrete waterproofing agents are typically available in powder and liquid forms. Powdered agents can be stored in bags or cans. Bagged powdered concrete waterproofing agents come in various packaging sizes, such as 10kg / bag, 15kg / bag, 25kg / bag, 40kg / bag, 50kg / bag, and 200kg / bag. Concrete mixing plants usually have large powder storage tanks for storing and using main powder raw materials such as cement, mineral powder, and fly ash. These large storage tanks are equipped with precise metering devices to ensure strict adherence to the mix proportions. However, due to space constraints, dedicated storage tanks are usually not provided for the relatively small quantities of concrete waterproofing agents. Therefore, in practice, bagged concrete waterproofing agents are typically added manually. However, manual addition is difficult to ensure accuracy, which can affect the effectiveness of the waterproofing agent. To avoid fluctuations in the waterproofing performance of concrete caused by inaccurate addition of bagged concrete waterproofing agents, the applicant has proposed a quantitative dispensing device for concrete waterproofing agents.
