摘要

浆料密度监测在工业领域是至关重要的。大多数工业,特别是水泥和矿物加工工业,都采用这种方法来获得高质量的产品。然而,大多数黄金加工行业的浸出碳(CIL)罐没有使用浆液密度监测系统。因此,很多时候,搅拌困难发生在浆料开始硬化时。因此,本文旨在为CIL储罐设计一个集成的抗硬化系统,在微控制器的帮助下,监测浆液的密度,以防止其硬化。浆液密度测量是在应变计压力传感器和一对液位传感器的帮助下实现的。对Atmega 328p单片机板进行编程,根据压力传感器和液位传感器分别显示的槽内浆液的压力值和液位值连续计算浆液的密度。微控制器通过激活发光二极管并在达到设定值时触发压电蜂鸣器来响应浆液硬化。利用Proteus 8.2设计套件软件对所设计的电路进行了仿真,验证了电路的功能。根据得到的结果,当达到设定值时,发光二极管和压电蜂鸣器被激活。结果表明,该防硬化系统可以有效地监测浆料的密度,防止浆料硬化。还建议采矿业可以采用所设计的系统来监测密度,以防止CIL储罐中的浆体硬化。关键词:碳浸池,料浆密度,应变式压力传感器,单片机

Design of an Integrated Anti-Hardening System for Carbon-In-Leach Tanks
Slurry density monitoring is of paramount importance in the industrial world. Most industries, especially cement and mineral processing industries, employ this method to obtain good quality products. However, most Carbon-In-Leach (CIL) tanks of gold processing industries do not use slurry density monitoring systems. As a result, many a time, agitation difficulties occur when the slurry begins to harden. This paper, therefore, seeks to design an integrated anti-hardening system for CIL tanks, with the aid of a microcontroller, to monitor the density of the slurry in order to prevent it from hardening. Slurry density measurement was achieved with the help of a strain gauge pressure sensor and a couple of level sensors. Atmega 328p  microcontroller board was programmed to continuously compute the density of the slurry from values of pressure and level of slurry in the tank indicated by the pressure and level sensors, respectively. The microcontroller responds to slurry hardening by activating a light emitting diode and triggering the piezo buzzer when a set point is reached. The designed circuit was successfully simulated using Proteus 8.2 design suite software to ascertain its functionality. Based on the results obtained, the light emitting diode and piezo buzzer activated when the set point was reached. It was concluded that the anti-hardening system is effective for constantly monitoring the density of the slurry to prevent it from hardening. It was also recommended that the mining industries could employ the designed system to monitor the density in order to prevent hardening of slurry in CIL tanks. Keywords: Carbon-In-Leach Tanks, Slurry Densisty, Strain Guage Pressure Sensor, Microcontroller
