The support is welded and fixed on the outer wall of a centrifugal dehydrator, a control box, a drying box and a hot air blower are fixed on the upper surface of the support, the hot air blower is connected with the drying box through an air inletpipe, the drying box is connected with the centrifugal dehydrator through a hot air pipe, a centrifugal barrel is arranged in the centrifugal dehydrator, the centrifugal barrel is fixed inside the centrifugal dehydrator through an upper fixing plate and a lower fixing plate, the top of the centrifugal dehydrator is provided with a stepping motor, the output end of the stepping motor is connectedwith the top end of the centrifugal barrel, a stirring device is arranged in the centrifugal barrel, the stirring device is composed of a stirring shaft and a spiral stirring fan blade, and the tail end of the centrifugal dehydrator is further fixedly provided with an exhaust fan. The device is high in drying speed, high in treatment precision and easy to operate.

Description

technical field [0001] The invention belongs to drying equipment, in particular to a centrifugal quick drying device for geotechnical test soil. Background technique [0002] Due to the special structure, the soil is very sensitive to moisture. In many soil engineering tests, it is necessary to qualitatively or quantitatively analyze the factors that water has an important influence on the soil, and the first step in these tests is to dry. At present, the drying method and the drying method are commonly used, but these methods take a long time and affect the progress of the test. At the same time, in order to calculate the content of water in the soil, the existing method is to weigh the soil before drying, weigh the soil after drying, and then calculate the content of water in the soil. Such an operation method is relatively It is complicated and takes a long time, and the soil is weighed after drying. Since the soil is easy to remain in the drying container, it is easy t...

Problems solved by technology

This drying instrument improves the drying speed and the measurement accuracy of moisture content to a certain extent; however, this drying instrument uses a large number of pipes. Too long pipes will affect the overall drying efficiency on the one hand, and on the other hand, water vapor will condense on the inner wall of the pipes. , which affects the accuracy of measurement; and this dryer is an internal circulation drying, although to a certain extent avoids the influence of moisture in the external air, but the internal air volume is small, the efficiency of hot air circulation is low, and the flow rate is small. Increasing the suction force will increase the probability of soil particle blockage and affect the smoothness of work.

In addition, when the moisture content in the soil is high, the moisture will promote the bonding of soil particles, especially affecting the efficiency and effect of hot air drying in the early stage, and prolonging the treatment time
