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.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 2 As shown, the slurry pipeline transportation device includes a thickening tank 1, an ore delivery pipeline 2, a filter screen 3, and an underflow pump 4. A valve B is set at the front end of the slurry pipeline segment blocked by debris, that is, the filter screen 3, and a valve C is set at the rear end. A negative pressure sensor 5 is arranged at an appropriate position at the rear end of the valve C. Set up a bypass pipeline to be connected in parallel with the slurry pipeline that will be blocked by sundries in this section. A bypass filter screen 8 is set in the coil pipeline, and the bypass pipeline is controlled by a bypass valve A. One end of the bypass pipe 7 communicates with the lower end of the concentration tank 1 , and the other end communicates with the underflow pump 4 .

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.
