Filling pipeline cleaning system and using method thereof

Abstract

The invention provides a filling pipeline cleaning system and a using method thereof. The filling pipeline cleaning system comprises a feeding system, a slurry pump and an air compressor; the feeding system is connected with the filling pipeline through the slurry pump; the air compressor is connected with the filling pipeline; the feeding system comprises a hopper, and a cement paste system and a water system which are arranged at the feeding hole end of the hopper; the cement slurry is pumped into the filling pipeline by the slurry pump, and the filling pipeline is cleaned for the first time; the water is pumped into the filling pipeline by the slurry pump to perform secondary cleaning on the filling pipeline; and gas is pumped into the filling pipeline by the air compressor, and the filling pipeline is cleaned for three times. A pumping pipeline efficient pipe washing mode with cooperation of cement paste, a small amount of water and high-pressure air is adopted, the pipe washing efficiency is high, and the pipe washing effect is good; and the water consumption is low, so that the water entering the goaf is less, the negative influence on the quality of the filling body is avoided, and the underground safety production is not threatened.

Description

technical field [0001] The invention relates to the technical field of mine tailings filling, in particular to a filling pipeline cleaning system and a method for using the same. Background technique [0002] At present, many mines in my country cannot realize the self-flow transportation of the filling slurry due to the location selection of the filling station and the wide range of filling services, but instead use pumping and pressurized transportation. After the filling is completed, the filling slurry in the filling pipe needs to be washed in time to prevent it from accumulating and hardening in the pipeline and causing the pipe blocking accident. [0003] For the pumped filling pipeline, the filling pump is generally used to pump clean water into the filling pipeline to clean the pipeline. However, the pumping and filling pipeline is usually long, and the flow rate of the washing water in the pipeline is slow, resulting in poor washing effect, longer washing time, and...

AI Technical Summary

Problems solved by technology

The shortcomings of this method are: (1) The cleaning of the pipeline by high-pressure water is the main factor that determines the cleaning effect. If the water does not meet the cleaning requirements, the subsequent wind cleaning still cannot achieve the effect; (2) The cleaning of high-pressure water Low efficiency, difficult cleaning and high water consumption
