Abstract (en)

A computerized system for monitoring, diagnosing, operating, and controlling various parameters and processes of basket centrifuges is presented. The computer control system actuates at least one of a plurality of control devices based on input from one or more monitoring sensors so as to provide real time, continuous, operational control of parameters related to feeding, filtering, washing, and dewatering. The monitoring sensors may sense other parameters, including machine operation parameters, and parameters related to the input and output streams of the centrifuge. Such control systems in combination with basket centrifuges are also presented. In a particularly preferred embodiment, the apparatus comprises a basket centrifuge with at least one sensor for providing input which is analyzed to provide information regarding optimal feed throughput rate and the average cake moisture at a given time. As a result of the analysis, at least one output may be generated to activate a control device that effects changes in feed rates, feed solids concentration, amount of wash, speed and duration of each segment in the cycle, total cycle time, temperature, torque, rpm, power consumption, and cake height. <IMAGE>
