Description

Technical Field

[0001] The utility model relates to a material level monitoring and alarm device for a powder storehouse, belonging to the technical field of material level monitoring equipment. Background Art

[0002] The production process of concrete requires raw materials such as aggregates, powders, Portland cement, admixtures and water. The raw materials are fully and evenly mixed in a concrete mixing station to obtain a concrete mixture. The raw materials need to be stored separately before being added to the concrete mixing station. Among them, powders usually need to be stored in raw material storage tanks.

[0003] Patent No.: CN213198244U, mentions a powder material level alarm system for a concrete raw material temporary storage tank. When the material level of the powder in the tank rises, the material level detection component is sensed, and then the material level detection component sends a signal. Under the action of the control component, the alarm component starts the alarm function, so that the operator can know the material level in the tank. At this time, stop feeding the powder to ensure that the tank is within the load-bearing range, which prevents the material level from being too high. However, during the powder feeding process, the feeding position is fixed, which will cause the powder to accumulate at the feeding point of the raw material storage tank, while there is less powder in the rest of the raw material storage tank, which will affect the accuracy of subsequent material level monitoring. Now there is an urgent need for a material level monitoring alarm device for a powder warehouse to solve the above-mentioned problems. Utility Model Content
