Machine-made sand quality detection equipment and detection method thereof

Abstract

The invention discloses machine-made sand quality detection equipment and a detection method thereof. The detection equipment comprises a feed port, a water content measurement device, a sample introduction device, a powder content measurement device, a dispersing device, an image collection device, an image analysis device and a recycling device; the water content measurement device comprises drying equipment for drying machine-made sand to prevent particle adhesion from affecting the image collection; and the powder content measurement device comprises a dust collector for removing stone powder from the machine-made sand to prevent the dust from affecting the image collection. The machine-made sand quality detection equipment has the following advantages: the water content measurement device and the powder content measurement device are added to preprocess the machine-made sand prior to the image collection so as to improve the reliability of a picture; and a detection method of granular shape correction granularity is added to correct a granularity detection result so as to eliminate the difference in the detection results of an image method and a sieving method.

Description

technical field [0001] The invention relates to the technical field of fine aggregate quality detection, in particular to a machine-made sand quality detection device and a detection method thereof. Background technique [0002] With the vigorous development of my country's basic construction, the demand for construction sand is increasing day by day. Due to the limitation of natural sand development, it has become an inevitable trend for machine-made sand to replace natural sand. However, due to the lack of manufacturing process and base material, the production quality of machine-made sand is uneven, and it cannot be put into use at will. Therefore, a kind of equipment is necessary to monitor the shape and quality of machine-made sand. The quality monitoring requires high precision and fast speed. [0003] Particle size and particle shape are two important control parameters of machine-made sand. The particle size and particle shape of the machine-made sand can be obtaine...

Problems solved by technology

[0004] The existing image-based on-line detection equipment for machine-made sand particle size and shape lacks the pretreatment process for machine-made sand, which causes dust and bonded machine-made sand to easily enter the image acquisition area and obtain unreliable images; the previous detection equipment ignored The falling range of the machine-made sand is outside the focal length of the camera, which makes the collected image blurred, and it is easy to get unreliable images, which makes the detection results deviate
