Problems solved by technology

[0003] Since the overflow water of the accident pool also contains a small amount of ore slurry, during the years of production and operation, the accumulation of ore slurry has led to the gradual reduction of the volume of the clean water tank, and finally the amount of water stored in the clean water tank can no longer meet the process requirements
The accumulation of ore slurry in the clean water pool will easily block the inlet pipe of the ring water pump, causing the ring water pump to fail or be damaged. It is urgent to clean up the accumulated ore in the clean water pool; however, the ring water pump is only connected to the clean water pool. equipment, causing hidden dangers and seriously affecting production

Abstract

The invention discloses a cross use system between material pools. The system is characterized in that the system comprises a clear water pool and an accident pool; the clear water tank is connected with a water circulating pump through a first pipeline, and the first pipeline is provided with a first valve; a preliminary sedimentation tank is arranged on the accident tank and is connected with the clear water pool through a second pipeline; and the first pipeline is connected with a third pipeline, the third pipeline is communicated to the accident pool, and i the third pipeline is provided with a second valve. The cross use system between the material pools solves the problem that water cannot be normally supplied when accumulated ores in the clear water pool are cleaned, and ensures production operation.

Description

technical field [0001] The invention relates to the field of long-distance iron ore concentrate pipeline transportation, in particular to a material pool cross-use system and control method for transforming an accident pool and a clear water pool of an intermediate pumping station. Background technique [0002] In the long-distance pipeline transportation system, the intermediate pump station plays the role of linking the preceding and the following. In the long-term production and transportation process, the slurry that does not meet the transportation requirements such as the head and the tail of the slurry, and the slurry discharged from the main pump flushing are discharged into the accident. The pool settles step by step, and after filtration, it overflows to the pre-sedimentation tank that comes with the accident pool. After filtering and sedimentation in the pre-sedimentation tank again, it overflows to the clean water pool, allowing the ore slurry to filter and settle...
