Description

Overturning clamp capable of rapidly dewatering

Technical Field

The invention belongs to the technical field of concrete raw material detection, and particularly relates to a turning clamp capable of quickly removing water.

Background

Concrete aggregate refers to a granular loose material which plays a role in skeleton or filling in concrete and is divided into coarse aggregate and fine aggregate, the coarse aggregate refers to pebbles, broken stones and the like, the fine aggregate refers to natural sand, artificial sand and the like, a lot of silt can be involved in concrete aggregate raw materials, the silt content of the aggregate can influence the strength, durability and other performances of the aggregate, the concrete aggregate is usually sampled, then the amount of the silt content in the concrete aggregate is observed manually, but the manual observation judges that the silt content of the concrete aggregate is subjective, so that the error of silt content measurement is large.

At present, the method of water washing detection is mostly adopted for detecting the mud content of concrete aggregate, the weight of the dried aggregate is detected after the dried aggregate is crushed in a container with holes, then the aggregate is put into cleaning equipment for cleaning, the cleaned aggregate is dried, and the weight change is detected to obtain the mud content of the aggregate. Then present anchor clamps only can shift splendid attire aggregate container, do not possess the dewatering effect, and the aggregate water content is higher after the washing leads to needing longer time when follow-up drying, influences detection efficiency.
