Lead-zinc ore dressing pulp heating device

Abstract

The invention relates to a lead-zinc ore dressing pulp heating device. The lead-zinc ore dressing pulp heating device comprises a pulp chamber inner wall, wherein a pipeline connector is arranged at the bottom of the pulp chamber inner wall in a communicating manner, the pipeline connector is communicated with a double-bin pipeline, at least two sets of output ports and input ports are formed in the pipeline connector, and the output ports and the input ports are communicated through heat distribution pipelines; and each heat distribution pipeline adopts a one-way backflow pipeline, the heat distribution pipelines are radially arranged along the bottom surface of the inner wall of a slurry chamber, the heat distribution pipelines are vertically arranged along the inner wall of the slurry chamber, and the upper ends of the heat distribution pipelines are connected and communicated through arc-shaped pipes or straight pipes.

Description

technical field [0001] The invention relates to the technical field of a lead-zinc beneficiation pulp heating device, in particular to a lead-zinc beneficiation pulp heating device. Background technique [0002] At present, the heating of the lead-zinc beneficiation slurry is uneven, the energy utilization efficiency is low, the ambient temperature of the heating site is high, the heat loss is large, and the energy waste is serious; the current heating method is mostly electric heating, and the heat conduction efficiency is high, but because other heat sources cannot be effectively used , although the structure is compact, but the heating cost is high, and the use of electric heating requires frequent anti-corrosion maintenance. Due to the high-temperature environment on site, the line is aging quickly and failures occur frequently. , high energy consumption and high cost; the current pulp heating device is in the high-temperature mixed slurry for a long time, which is prone...

[0002] At present, the heating of the lead-zinc beneficiation slurry is uneven, the energy utilization efficiency is low, the ambient temperature of the heating site is high, the heat loss is large, and the energy waste is serious; the current heating method is mostly electric heating, and the heat conduction efficiency is high, but because other heat sources cannot be effectively used , although the structure is compact, but the heating cost is high, and the use of electric heating requires frequent anti-corrosion maintenance. Due to the high-temperature environment on site, the line is aging quickly and failures occur frequently. , high energy consumption and high cost; the current pulp heating device is in the high-temperature mixed slurry for a long time, which is prone to corrosion and leakage, and the accident of leakage point caused by electric heating is very harmful, and frequent maintenance and spot checks have a great impact on production , so a lead-zinc beneficiation slurry heating device is needed
