Description

technical field [0001] The invention relates to a testing device and method for the transport performance of filling slurry, belonging to the technical fields of fluid mechanics and pipeline transport engineering. Background technique [0002] In the process of researching the flow properties of filling slurry, in order to transport the filling slurry smoothly, it is necessary to test the relevant parameters required for the calculation of the rheological parameters of the filling slurry, so as to achieve the purpose of correctly designing the transportation pipeline network. Therefore, it is necessary to adopt appropriate technical measures to reduce labor intensity. When different test devices are used, the accuracy and effect of the measurement will be different. In general, in order to ensure the measurement effect of the filling slurry delivery test, the commonly used device is to manually stir the filling slurry, and then use a bucket to fill the slurry, and lift the b...

Problems solved by technology

In general, in order to ensure the measurement effect of the filling slurry delivery test, the commonly used device is to manually stir the filling slurry, and then use a bucket to fill the slurry, and lift the bucket by bucket to the platform at the height of the storage bin. Pour the filling slurry into the storage bin. After the filling slurry is transferred, open the valve at the mouth of the discharge pipe. When the filling slurry flows down from the storage silo, use a bucket to pick up a bucket of filling slurry and weigh it. After the filling slurry in the discharge pipe is still, use a ruler to measure the relevant parameters, and then calculate the rheological parameters of the filling slurry. In this way, the measured results are often due to the filling slurry cannot be discharged in a short time. , the coarse and heavy particles will settle to a certain extent, and the slurry will be lost in the repeated transfer process, so there will be certain errors, which will affect the accuracy of the test results. At the same time, this method is more cumbersome. Moreover, there will be certain hidden dangers in the busy operation process, and the parameters to be measured cannot be obtained quickly and labor-savingly, so the measurement time is increased and the labor intensity is extremely high. At this time, a convenient, labor-saving, and safe device and method are needed to obtain Good test effect, that is, it is convenient and fast to measure the rheological parameters of the filling slurry, saving time, reducing labor intensity and reducing test errors
