Building-aggregates washing, screening and drying integrated modular sampling device and use method

Abstract

The present invention provides a washing, screening and drying integrated modular sampling device for construction aggregates. In light of the problem in current soil tests of low work efficiency due

Description

[0002] During the test of building materials, it is necessary to clean building aggregates such as sand and stones to remove impurities such as silt. However, the manual cleaning effect is poor, and all water-soluble impurities cannot be fully removed. After washing is completed, the aggregates are dried or put into an oven for drying to prevent excess moisture from affecting test data. However, drying needs a certain site, and the weather conditions can affect the drying effect, so that the stability of the test data is reduced. A fixed oven can only dry a part of aggregates at a time, and it is necessary to constantly change the aggregates. After drying, in order to meet the needs of test particle size distribution, building aggregates with different particle sizes need to be screened out. When an ordinary test sieve is used, the working efficiency is low because of limited area of the sieve. In the above-mentioned process, a number of instruments and equipment, such as a test sieve and an oven, are involved, and the building aggregates are large in dead weight, so that time and energy are wasted during the operation.

[0003] Therefore, it is of great significance to develop a building-aggregates washing, screening and drying integrated modular sampling device. SUMMARY
