Abstract

The invention discloses an intelligent powder sampling device. The device comprises a branch pipe which is connected and communicated with a main powder conveying pipeline, an intelligent control valve which is mounted at one end, close to the main conveying pipeline, of the branch pipe and is used for controlling the conveying of the powder in the branch pipe, and a material collecting bag which is connected with the other end of the branch pipe and used for containing the powder samples. The device further comprises a vacuum pump, the vacuum pump is connected with the material collecting bag and used for conducting vacuum treatment on the material collecting bag, and the intelligent control valve is further used for conducting waste and dust cleaning through compressed air entering the branch pipe. The whole sampling process is automatically completed, manual operation is not needed, and personnel safety risks in the sampling process are eliminated.

Description

technical field [0001] The invention belongs to the technical field of powder sampling, and in particular relates to a powder intelligent sampling device and method. Background technique [0002] Concrete refers to a building material that uses cement, fly ash, mineral powder and other powder materials as cementing materials, sand and stone as aggregates, and mixes with water and chemical admixtures in a certain proportion. Powder materials in ready-mixed concrete plants are usually transported by tank trucks and stored in powder tanks. After the tank truck arrives at the site, the discharge pipe of the tank truck is connected to the sorting conveying pipe on the powder tank, and the compressed air is used to generate air flow, so that the powder in the tank truck is filled into the powder tank. [0003] Since the powder (ie cementitious material) used in the production of concrete is the source of concrete strength, its quality is crucial to the development of various prop...
