A pipeline sand transport surge tower

Abstract

The invention relates to a water conservancy facility, and particularly discloses a pressure regulating tower for sediment transport in pipeline. The pressure regulating tower comprises a sediment transport pipeline, and is characterized by also comprising a PLC (programmable logic controller) control system; the sediment transport pipeline is upwards connected with a standing pipeline; an impounding reservoir is arranged above the sediment transport pipeline; the upper outlet of the standing pipeline is bent downwards and faces the impounding reservoir; a non-return valve is connected between the impounding reservoir and the standing pipeline; the impounding reservoir is provided with a drain valve; the impounding reservoir is matched with a submerged pump for supplementing water into the impounding reservoir; a pressure sensor is arranged in the impounding reservoir; the non-return valve, the drain valve and the pressure sensor are respectively in circuit connection with the LC control system. When a primary pump station or a secondary pump station breaks down, the pressure regulating tower disclosed by the invention is capable of regulating slurry amount in the sediment transport pipeline, so the normal operation of a whole sediment transport system is maintained; faults can also be cleared in time, and the transport efficiency is increased.

Description

[0001] (1) Technical field [0002] The invention relates to a water conservancy equipment facility, in particular to a pipeline sand transport pressure regulating tower. [0003] (2) Background technology [0004] While promoting the economic development of various regions, the coal mining industry has also brought many negative impacts, resulting in relatively serious geological and ecological damage, some rivers being cut off, roads, bridges and culverts breaking and sinking, and hydropower facilities being damaged. The coal mining subsidence area has accumulated water all the year round, the area of ​​arable land has decreased, the grain production has been reduced, and production has ceased, and the agricultural economy has suffered huge losses. The houses in the coal-pressed villages are cracked, tilted and collapsed, which has seriously threatened the safety of life and property of the people in the collapsed area, and also seriously affected the layout and process of ur...

AI Technical Summary

Problems solved by technology

[0005] However, in the process of pipeline sand transport, when the secondary pump station fails, the amount of sediment transported in the pipeline will exceed the sand transport capacity of the secondary pump station, resulting in equipment damage

When the secondary pumping station works normally, but the primary pumping station breaks down and fails to reach the designed delivery flow, the secondary pumping station’s delivery volume is insufficient, causing the equipment to run idly, damaging the equipment, and wasting energy. Shutdown for maintenance, which will cause great losses to the entire sand conveying system
