Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a device for quickly detecting water content in sandstone aggregates. Background Art

[0002] Sand and gravel aggregate is a general term for materials such as sand, pebbles (gravel), crushed stone, block stone, and rubble stone in water conservancy projects. Sand and gravel aggregate is the main building material for structures such as concrete and stacked stones in water conservancy projects. The moisture content of sand and gravel aggregate is one of the key factors affecting the quality of concrete. Too much moisture content in aggregate will cause the final concrete to be too thin. Therefore, technicians need to understand the moisture content of aggregates in real time in order to configure concrete that meets the standards. The moisture content of sand and gravel aggregates on the project site inevitably fluctuates greatly. This moisture content is directly related to the water-cement ratio, so it will have a greater impact on the quality of the finished concrete, and a moisture detection device is needed.

[0003] Most of the existing water content detection devices use a stirring rod to stir the water during detection to speed up drying, but this will generate a lot of dust, which is not conducive to protecting the environment and the health of the operator.

[0015] Technical effects and advantages of the utility model:

The weighing sensor confirms the weight of the dried sand and gravel aggregates and transmits it to the weighing display screen. The calculation method of the moisture content of sand and gravel is: subtract the wet weight of the sand and gravel aggregates obtained in the weighing frame from the dry weight of the sand and gravel aggregates obtained in the containing frame after drying, and then divide it by the wet weight. Multiply the obtained value by percentage to quickly obtain the moisture content of the sand and gravel aggregates.

[0018] 3. Through the setting of the collecting bucket, dust suction fan, output pipe and dust removal bag, when in use, the dust in the sand and gravel aggregate is vibrated and raised, the dust suction fan is started, and the dust inside the box is sucked into the collecting bucket through the output pipe. The dust removal bag in the collecting bucket absorbs the dust. The vibration generated by the eccentric wheel driven by the vibration motor will also be transmitted to the inside of the collecting bucket, and the dust removal bag will be beaten, so that the dust in the dust removal bag falls into the collecting bucket for processing, thereby avoiding dust damage to the sand and gravel aggregate moisture detection device, affecting the detection results, and increasing the service life of the moisture detection device.
