Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a device for measuring the mud content of concrete aggregates. Background Art

[0002] Concrete aggregate generally refers to the granular, loose material used to form the concrete skeleton or filler. It is primarily categorized as coarse aggregate and fine aggregate. Coarse aggregate typically includes larger particles such as pebbles and crushed stone, while fine aggregate includes smaller particles such as natural sand and manufactured sand. During the concrete production process, the selection of these aggregates has a direct impact on the concrete's strength, durability, and other key performance indicators. Aggregate raw materials often contain varying degrees of silt, and this silt content plays a decisive role in the concrete's performance. High silt content can lead to reduced strength and durability, making it crucial to control the silt content in the aggregate. To ensure that the aggregate quality meets project requirements, rigorous sampling and testing are typically performed. During the sampling process, professionals manually observe and assess the silt content in the concrete aggregate to ensure it remains within acceptable limits.

[0003] When the existing concrete aggregate mud content measuring device is used, it is not convenient to quickly filter the washed away mud and wastewater during the screening and spraying of aggregates and soil, which easily causes residual mud on the surface of the aggregate. After the screening is completed, it is not convenient to quickly separate the aggregate in the screening cylinder, so that more aggregate will remain in the screening cylinder, thereby reducing the accuracy of the concrete aggregate mud content measurement and having limited applicability.

[0004] For example, Chinese patent CN219870848U discloses an automatic device for measuring the mud content of concrete, including a filter frame and a uniform flushing mechanism, which is arranged inside the filter frame; the filter frame includes a frame body, a lower leakage hole and a nozzle; the uniform flushing mechanism includes a drive chamber opened at the bottom of the filter frame, a transmission hole connected to the inner wall of the filter frame is opened at the top of the inner wall of the drive chamber, a drive rod is sleeved inside the transmission hole, and one end of the drive rod extends into the interior of the drive chamber.

[0005] The automatic measuring device for the mud content of concrete has the following disadvantages: although the rotating aggregate is fully contacted with the spraying water to achieve efficient flushing of the aggregate, it is not convenient to quickly filter the washed away soil and wastewater during the screening and spraying of the aggregate and soil, which easily causes residual soil on the surface of the aggregate, and after the screening is completed, it is not convenient to quickly separate the aggregate in the screening cylinder, so that more aggregate will remain in the screening cylinder, thereby reducing the accuracy of the measurement of the mud content of the concrete aggregate and having limited applicability.

[0006] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
