Dewatering treatment device for low-concentration pulp in pipes and treatment method of dewatering treatment device

Abstract

The invention relates to a dewatering treatment device for low-concentration pulp in pipes and a treatment method of the dewatering treatment device. An input end of a pulp flowing sedimentation device is connected with a low-concentration ore pulp inlet pipe, two output ends of the pulp flowing sedimentation device are respectively connected with a pulp stirring tank and a water pond, wherein the output end connected with the pulp stirring tank is located at the bottom of the pulp stirring tank, an output end of the pulp stirring tank is connected with a main delivery pipe via an underflow pump, and the radial transaction area of a cavity of the pulp flowing sedimentation device is larger than that of the low-concentration ore pulp inlet pipe. By the aid of the pulp flowing sedimentationdevice which can greatly reduce the flowing speed of pulp, the low-concentration pulp flowing in the pulp flowing sedimentation device can realize partial sedimentation and layering in the pulp flowing sedimentation device, then distribution of water or pulp with different concentrations is completed by means of adjusting a valve, and treatment for head pulp or tail pulp with the concentration incapable of reaching the standard during delivery of ore pulp pipes is realized well.

Description

technical field [0001] The invention relates to a device and method for pipeline transportation, concentration separation and dehydration treatment of slurry, in particular to a device for dehydration treatment of low-concentration slurry in pipelines and a treatment method thereof. Background technique [0002] During the pipeline transportation of iron concentrate slurry and the dehydration treatment of iron concentrate slurry, the slurry material will be transported at a specific concentration, and the concentration change will not be too large. will not have a major impact. [0003] However, if the slurry is transported in batches or graded (that is, transporting one end of the iron concentrate slurry and then transporting a section of clean water), there will be a combination of slurry and water. In this way, the slurry concentration at the slurry-water junction It will be greatly reduced, and the large concentration reduction of the slurry does not meet the requiremen...

AI Technical Summary

Problems solved by technology

[0005] The invention designs a low-concentration slurry dehydration treatment device and its treatment method in pipelines, which solves the technical problem that in the existing slurry pipeline transportation, when a small amount of slurry concentration is too low, it cannot meet the requirements of pipeline transportation and dehydration process requirements, and the cost of existing treatment processes is too high
