Description
Technical Field
The utility model relates to the technical field of paste filling, in particular to a paste filling loop conveying test device.
Background
In the mining industry, filling mining methods are often used to protect mines in order to prevent collapse of different magnitudes in the mined out area. The filling mining method is to feed filling materials (filling materials: slurry paste) into the mined-out areas along with the advance of mining work so as to form good support for the ground, so that mineral resources can be recovered to the maximum extent, the underground is protected, and collapse of the ore goaf is avoided.
In the process of filling a mine goaf, a conveying pipe (conveying pipe: filling ring pipe) for guiding a filling paste is paved in a roadway leading to the mine goaf, then cement paste is led in from one end of the conveying pipe, the cement paste is guided to the goaf through the conveying pipe, and the filling process of the goaf is completed when the slurry paste in the goaf is solidified. However, in the actual filling process, the flowability and pumpability of the filling material (filling material: filling paste) in the delivery tube are greatly different due to the difference of the filling materials. Therefore, a set of experimental data capable of simulating various mine working conditions to find the optimal filling material proportion, obtain the slurry paste flow, the slurry paste density and the slurry paste solidification time, and have good guiding significance for improving the actual mine filling operation is required to be developed.

(2) The running direction of the paste conveying loop in the paste filling loop simulation test system is different from the running direction of actual mine filling to a certain extent, the test scale is relatively small, and the slurry paste conveying and the slurry paste flowing state are influenced, so that certain errors exist in the measured slurry paste performance data under the condition.
Therefore, the paste filling mode needs to be improved and designed to solve the problem that the accuracy of the measured slurry paste performance data is not high because the slurry paste in the filling loop is conveyed only by adopting the pumping mode to perform the flowing state test when the simulation test of the paste filling loop is performed in the prior art.
