AI Technical Summary

Technical Problem

Existing small-scale sand mixing devices have low automation levels. Fixed liquid levels and rotation speeds lead to uneven mixing. Manual monitoring poses safety risks. Independent parameters cannot be dynamically matched, requiring on-site supervision and resulting in high labor intensity.

Method used

The system uses a liquid level radar and level gauge linked with the control system to achieve automatic liquid filling, precise sand filling, adaptive speed adjustment, quantitative additive injection, and pressure-linked liquid discharge. Combined with a remote control system, it integrates multi-parameter automated operation.

Benefits of technology

It improves the accuracy and efficiency of sand mixing solution preparation, reduces manual labor intensity and safety risks, ensures stable performance of sand mixing solution, reduces energy consumption, eliminates overpressure safety hazards, and enables remote control throughout the process.

Abstract

This invention discloses a small sand mixing device, including a base, a mixing tank and a sand inlet hopper mounted on the base, a mixing assembly inside the mixing tank, a feeding assembly between the sand inlet hopper and the mixing tank, a level radar and a level gauge mounted on the top of the mixing tank, both of which are associated with a control system. The control system includes an explosion-proof distribution box, which is associated with a remote terminal via wireless communication. A dry-addition pump, a bonding pump, and a liquid-addition pump are also connected to the base, all of which are connected to the mixing tank via pipelines. The bottom of the mixing tank is connected to a discharge pump via a pipeline. A fracturing delivery pipeline is connected to the mixing tank, and a flow meter is connected to the fracturing delivery pipeline. This invention enables automatic liquid addition, precise sand addition, adaptive speed adjustment, quantitative additive addition, pressure-linked liquid discharge, and full remote control, improving the accuracy and efficiency of sand mixing solution preparation while reducing manual labor intensity and safety risks.
