Problems solved by technology
[0005] In view of the existing aggregate drying box in the prior art, the container filled with aggregate is directly placed in the drying box for drying during use. The drying speed is slow and the drying time is long, resulting in the aggregate The moisture content detection efficiency is low, which delays the progress of the project. At the same time, the uneven drying of the aggregates leads to a large error in the detected moisture content of the aggregates, which reduces the quality of the project. The purpose of the present invention is to provide a concrete for water conservancy and hydropower projects. Aggregate rapid drying box for detection, which can well solve the problems raised in the background technology

The invention discloses a rapid aggregate drying box for concrete testing in water conservancy and hydropower projects, which comprises an oven. The top of the oven is provided with a lifting device; the aggregate is gradually Lift upwards and continue to fall downwards in the form of a waterfall. The surface of the aggregate can be completely exposed during the falling process, so that the aggregate can be heated evenly to ensure that the aggregate is evenly dried, so that the moisture content data of the aggregate obtained through detection is more accurate. At the same time, the exposed area of the aggregate is increased, the moisture inside the aggregate evaporates faster, the drying speed of the aggregate is increased, and the progress of the project is accelerated. The hot air is generated through the oven, and the hot air quickly passes through the gap between the aggregates. , so that the moisture inside the aggregate can evaporate quickly, which increases the drying speed of the aggregate. Through the dust-proof and ash-cleaning device, the external dust and impurities will not be mixed into the aggregate, which increases the accuracy of detection and improves the quality of the aggregate. The practicality of the quick drying box.
Description
technical field [0001] The invention relates to the field of quick drying boxes for aggregates, in particular to a quick drying box for aggregates used for concrete testing in water conservancy and hydropower projects. Background technique [0002] The laboratory is a permanent inspection institution in the construction process of water conservancy and hydropower projects. Its main duties are to conduct quality inspection of on-site construction materials and determine various technical parameters such as water-cement ratio, aggregate gradation, etc. in combination with the actual situation on the site, and participate in the analysis of concrete quality accidents etc. In on-site concrete construction, the gradation of coarse aggregate is often the main index affecting the workability of concrete, and the fluidity of well-graded concrete will be better, which is especially obvious in pumped concrete. In the process of determining the aggregate gradation, it is generally nece...
