Description

Technical Field

[0001] The utility model relates to the technical field of powder bin sampling equipment, in particular to a powder conveying pipe sampling device. Background Art

[0002] Concrete is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as cementitious powder material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed to obtain cement concrete.

[0003] Concrete powder refers to the fine powder made by grinding raw materials such as cement, limestone, slag, fly ash, coal ash, quartz powder, etc. It is one of the raw materials of concrete. Concrete is made by mixing raw materials such as cement, sand, gravel, powder, etc., and is a high-strength and high-durability building material formed after solidification and hardening.

[0004] After concrete is mixed and produced, it is necessary to conduct sampling inspection to ensure that the concrete leaving the factory meets the production standards and reaches higher standards. The unqualified concrete sampling is generally due to the unqualified quality of the powder or equipment problems, resulting in problems with the proportion of raw materials entering the mixer. Currently, sampling is conducted after the concrete is mixed. If unqualified concrete is found, the concrete cannot be adjusted and reused again, resulting in a waste of raw materials and costs, and low efficiency of concrete inspection. Powders are generally transported through pipelines. The existing sampling directly opens the pipe to connect the branch pipe and installs a valve, which wastes the principle and causes serious pollution during sampling.

[0005] Therefore, there is an urgent need to design a powder conveying pipe sampling device, which can sample and inspect the powder before concrete mixing through an integrated sampling box to solve the problems of low efficiency and high cost of sampling after concrete mixing and simple powder sampling structure that pollutes the environment.
