Description

Sand mud content detection device for concrete Technical Field The application relates to the technical field of sand and mud content detection, in particular to a sand and mud content detection device for concrete. Background In the construction engineering, concrete is used as one of the most commonly used building materials, the performance of the concrete directly influences the structural safety and the service life of a building, sand is used as a main constituent of the concrete, the quality of the sand plays a crucial role in the performance of the concrete, and the mud content in the sand is one of key factors influencing the strength, the durability and the workability of the concrete, so that accurate and rapid detection of the mud content of the sand for the concrete is of great importance in ensuring the engineering quality. The prior patent (bulletin number: CN 212646381U) discloses a sand and mud content detection device for concrete, which is provided with a bin, four walls of the bin are provided with a screen with the aperture of 0.5-1mm, a shell is arranged outside the bin, the shell is communicated with the four walls of the bin, a round hole is formed in the middle of the bottom of the bin, a rotating shaft penetrates through the middle, a stirring blade is arranged on the rotating shaft, a waterproof plug is arranged at the joint of the rotating shaft and the bottom of the bin, the rotating shaft is connected with a middle shaft arranged below the bottom of the bin along a motor, the bottom of the bin is provided with a weight sensor, the weight sensor is connected with a display screen above the shell, the bottom of the bin is additionally provided with a heating rod, the motor is arranged on a spacer, a mud bin is formed between the spacer and the shell, and a water outlet is formed at the lower edge of the mud bin. However, in the prior art, the detection method of the sand and mud content in concrete mainly comprises the steps of sampling, stirring and separating, filtering, drying and the like, wherein in the filtering step, due to the fact that a filter screen in the existing equipment is inconvenient to replace, when the filter screen is worn severely or the aperture deviation is large, the filter screen can be leaked or misplaced, and due to the fact that the diameters of sand particles in the market are different, the filter screen cannot be replaced, and then the sand and mud with different particle sizes cannot be separated.
