Ore slurry pipeline transport device and anti-blocking control method thereof

Abstract

The invention discloses an ore slurry pipeline transport device and an anti-blocking control method thereof. The ore slurry pipeline transport device comprises a concentration tank (1), an ore transporting pipeline (2), a filter screen (3), an underflow pump (4) and a bypass pipeline (7), wherein the front end of the filter screen (3) is provided with a valve (B), while the rear end is also provided with a valve (C); the rear end of the valve (C) arranged at the rear end of the filter screen is provided with a negative pressure sensor (5); the bypass pipeline (7) is connected in parallel in the front of the valve (B) arranged at the front end of the filter screen and behind the valve (C) arranged at the rear end of the filter screen and is controlled by a bypass valve; the negative pressure sensor (5) detects the pressure inside the ore transporting pipeline; and when an ore slurry pipeline is detected to be in a negative pressure state, the bypass valve is automatically opened and simultaneously the valves at the front end and the rear end of the filter screen are closed to enable the ore slurry to pass through the bypass pipeline. The ore slurry pipeline transport device and the anti-blocking control method thereof solve the problem that impurities of a conventional ore transporting pipeline filter screen can be cleared only after the underflow pump is stopped, and can improve the transporting efficiency and save the cost.

AI Technical Summary

Benefits of technology

The technical effect described this new design improves the performance of an apparatus called a conveyor system used for processing or transporting materials like coal (coal). It includes two main components - one is connected through pipes between them while another component connects directly into the material being processed. This allows fluid communication without blocking any parts from moving around inside the machine's structure.

Problems solved by technology

This patented technical problem addressed by this patents relates to prevention of blockages caused during mineral processing operations due to deposits from entering pipelines that carry liquid or gaseous materials like water or gases through filters used for filtering purposes.
