Slurry concentration treatment system and method

Abstract

The invention provides a slurry concentration treatment system and method. The system comprises a slurry agitator bath, a valve, slurry pipelines, a pond, an underflow pump, and a slurry flow participation region, wherein the three slurry pipelines are added to the slurry flow participation region; the upstream slurry pipeline is a low-concentration slurry entering pipeline; the downstream slurry pipeline is a clean water outlet pipeline; the bottom slurry pipeline is a high-concentration slurry outlet pipeline; a low-concentration slurry material entering the slurry flow participation region is from circulating slurry of the external part and the slurry agitator bath. The slurry material can achieve the slurry concentration meeting the subsequent conveying or dewatering technology after being subjected to deposition treatment once or for a plurality of times, the problem of concentration treatment of the slurry materials with overlarge concentration deviation and over-low concentration is effectively solved, the concentration of the slurry material with low concentration within the specified range is improved, so that the slurry material accords with the requirements of pipeline conveying and dewatering technologies, meanwhile, the system disclosed by the invention is simple in overall structure, and easy to achieve, the invested cost is much smaller than that of a set of concentrator equipment, and compared with the prior art of adopting an automobile to transport after naturally airing, the treatment scheme has larger economic value.

Description

technical field [0001] The invention relates to the technical field of slurry pipeline transportation, and more particularly relates to a slurry concentration treatment system and method capable of meeting the requirements of slurry pipeline transportation, concentration separation and dehydration treatment. Background technique [0002] During the pipeline transportation of slurry or dehydration treatment of slurry, the slurry material needs to meet a specific concentration distribution, and the concentration change should not be too large, only in this way will it not have a greater impact on pipeline transportation or dehydration treatment. However, at the main station or starting station of slurry pumping, batch delivery or graded delivery of slurry often occurs, and slurry-water combination will inevitably occur during batch and graded delivery of slurry, and slurry-water combination will lead to The slurry concentration at the junction will be greatly reduced, and ther...

Problems solved by technology

[0003] The purpose of the present invention is to aim at the above-mentioned defects in the prior art, and innovatively design a simple and low-cost slurry concentration treatment system and method, the system includes a slurry stirring tank, valves, slurry pipelines, water pools, underflow pumps and slurry In the fluid sedimentation area, three slurry pipes are installed on the slurry flow sedimentation area, the upstream one is a low-concentration slurry inlet pipe, the downstream one is a clear water outlet pipe, and the bottom one is a higher-concentration slurry outlet pipe , and the low-concentration slurry material entering the slurry flow sedimentation zone comes from the outside and the circulating slurry in the slurry stirring tank. After one or more settling treatments, the slurry material can meet the requirements of subsequent transportation or dehydration. The slurry concentration required by the process effectively solves the problem of concentration treatment of slurry materials with large concentration deviation and low concentration, and improves the concentration of slurry materials with low concentration within the specified range, so that it meets the pipeline transportation and dehydration process At the same time, the overall structure of the system of the present invention is simple and easy to implement, and the input cost is far less than a set of concentrator equipment, and the treatment scheme has greater economic value than the prior art in natural air-drying and transportation by car
