Description

Technical Field

[0001] This invention relates to the field of slurry preparation technology, and in particular to an intelligent filling slurry preparation and metering device. Background Technology

[0002] In the process of mining, in order to ensure the safety and stability of the mine and minimize the impact on the environment, it is usually necessary to carry out backfilling operations in the goaf. The backfilling material is mainly composed of tailings sand, water and cement powder mixed in a specific ratio. When preparing the backfilling slurry, a metering device is required to weigh the material to ensure the accuracy of the material ratio.

[0003] According to application number CN202021809407.6, a filling slurry preparation system includes a thickener, an emergency tank, a mixing system, a filling pump, and a cement conveying and metering device installed at the cement silo discharge port. The thickener and filling pump are both located on the ground, with a stepped pit excavated below ground. The mixing system consists of a high-speed flexible mixer. The high-speed flexible mixer and the emergency tank are arranged from top to bottom within the pit. A hopper and / or a thickener pump are also arranged in the pit between the high-speed flexible mixer and the emergency tank. The sand discharge port of the thickener and the outlet of the cement conveying and metering device are connected to the feed port of the high-speed flexible mixer. The hopper is connected between the discharge port of the high-speed flexible mixer and the filling borehole of the underground filling pipeline network. The thickener pump is connected between the discharge port of the high-speed flexible mixer and the pump hopper of the filling pump. This utility model has fewer slurry preparation steps, reducing plant construction investment and allowing for flexible equipment layout.

[0016] This invention provides an intelligent filling slurry preparation and metering device, which has the following beneficial effects: This invention facilitates the maintenance and replacement of the spiral feed roller through its maintenance mechanism. When the spiral feed roller operates, it drives the feeding component to rotate through the coordinated action of the fixed pulley, connecting pulley, and connecting synchronous belt, thereby stably conveying the material in the storage bin to the conveying pipe. The design of the feeding component not only improves the feeding efficiency but also effectively prevents material blockage at the outlet. When maintenance of the spiral feed roller is required, simply loosen the first and second fastening nuts, then open the first and second maintenance covers to directly observe the working status of the spiral feed roller and perform corresponding maintenance. Furthermore, by pulling and removing the connecting retaining ring, and then pushing the spiral feed roller upward, the connecting insert is disengaged from the connecting slot. Simultaneously, by moving the limit slider to release the restriction on the installation slider, the spiral feed roller can be tilted and pulled upward, facilitating replacement operations, significantly improving work efficiency and reducing labor intensity.

[0017] Furthermore, the feeding mechanism enables linear adjustment of the material conveying speed. After the vibrating motor starts, it drives the eccentric wheel to rotate, causing the storage bin to vibrate, thus preventing the material from adhering to the bin wall. As material is continuously added to the weighing bin, the weighing device detects the weight change in real time and feeds the signal back to the frequency converter. The frequency converter adjusts the power supply frequency of the feeding drive motor according to the weight signal, thereby controlling the speed of the feeding drive motor and achieving precise adjustment of the feeding speed. This not only improves the feeding accuracy but also enables refined production management, effectively improving overall production efficiency and reducing labor and material costs.

[0018] Furthermore, the aforementioned mechanism not only facilitates the maintenance and replacement of the spiral feed roller, improving the work efficiency of both stages and reducing the labor intensity of operators, but also enables intelligent control of the material conveying process, significantly improving feeding accuracy and production efficiency.
