Temperature-controlled soil continuous grinding and screening device

Abstract

The invention relates to a temperature-controlled soil continuous grinding and screening device, which is characterized in that a feeding hopper is arranged at the top of a double-layer composite shell, the lower nozzle of the feeding hopper is connected to the central hole of a umbrella-shaped fixed grinding disc, the lower part of the umbrella-shaped fixed grinding disc is provided with an umbrella-shaped dynamic grinding disc opposite to each other, a discharge elbow is connected to the bottom discharge opening of a material-falling bin, and an inclined screen cylinder is connected to the pipe port of a discharging elbow via a bearing bayonet; a collection box is arranged below the barrel body of the screen cylinder, a multi-stage conveyor belt is arranged in a double-layer composite shell to transport materials layer by layer upwards, the bottom layer belt of the multi-stage conveyor belt extends to the position below the particulate discharging port of the screen cylinder, and thetop belt of the multi-stage conveyor belt extends to the bypass discharge port of a feeding hopper. The temperature-controlled soil continuous grinding and screening device solves the problems of complex steps and low processing efficiency existing in current laboratory soil treatment, effectively overcomes various interference factors in a soil grinding process, and improves the reliability of the research data and the research results.

Description

technical field [0001] The invention relates to a soil experiment processing device, in particular to a temperature-control type soil continuous grinding and screening device. Background technique [0002] Soil is an important material basis for maintaining sustainable crop production and ensuring food supply security, and its quality and environmental issues have received more and more attention. Most analysis and simulation studies involving soil require a series of pre-treatments such as air-drying, grinding and screening of soil samples collected in the field. The workload is heavy and time-consuming, which seriously reduces the work efficiency of the laboratory. [0003] Moreover, under the current experimental conditions, there are many interference factors affecting the final analysis or experiment of soil. For example, most studies involving soil organic carbon require pretreatment in a low-temperature environment (suitable for 0-4°C) to reduce the activity of micro...
