背景技术 Background technique
水泥助磨剂是一种为了提高粉磨效率，降低粉磨电耗，提高水泥粉磨细度和水泥强度的化学添加剂。在不改变工厂现有工艺和设备条件的前提下，在粉磨过程中，添加微量或少量的水泥助磨剂会影响粉磨作业的机械力，达到改善粉磨过程的目的。然而在以前的生产过程中，水泥助磨剂加入量的多少，需要操作工现场控制，由于人工操作的不确定性，导致不能及时严格按比例添加，也难以随水泥产量进行及时调整。助磨剂添加装置的开启或者停止需要操作工进行，中控不能对助磨剂的开启或者停止进行干预；不能显示液体助磨剂加入的瞬时流量和累计流量，在中控室不能对助磨剂的添加情况进行有效的跟踪；无报警设置，设备出了故障，操作人员无法第一时间获知，容易造成助磨剂浪费；不宜计算水泥生产成本；因此给水泥的生产和助磨剂的使用，带来极大的不便。 Cement grinding aid is a chemical additive to improve grinding efficiency, reduce grinding power consumption, and improve cement grinding fineness and cement strength. On the premise of not changing the existing process and equipment conditions of the factory, adding a small amount or a small amount of cement grinding aids will affect the mechanical force of the grinding operation during the grinding process and achieve the purpose of improving the grinding process. However, in the previous production process, the amount of cement grinding aid to be added needs to be controlled by the operator on site. Due to the uncertainty of manual operation, it cannot be added in a timely and strict proportion, and it is difficult to adjust it in time with the cement production. The opening or stopping of the grinding aid adding device needs to be done by the operator. The central control cannot intervene in the opening or stopping of the grinding aid; Effectively track the addition of the cement; without alarm settings, if the equipment fails, the operator cannot be notified immediately, which will easily cause waste of grinding aids; it is not suitable to calculate the cost of cement production; therefore, for the production of cement and the use of grinding aids, bring great inconvenience.
