Abstract
DEVELOPMENT OF MATHEMATICAL MODEL OF SLUDGE CLEANING PROCESS 0F ABRASIVE METAL TREATMENT IN THE CLEANING SOLUTION Vernyhora V.D. Abstract At present engineering companies have huge problems with waste sludge obtained after components grinding. Thousands tons of them are produced every month. They are not utilized and are taken for special storage, but they worsen environmental safety. The composition of this sludge is a mixture of crushed chips, abrasive, technical oil, coolants, dust and so on. Percentage of crushed metal chips in sludge abrasive processing of metals is 60 - 80%. Sludge processing of abrasive metal treatment is reasonable and economically beneficial when global prices for raw materials and the development of powder metallurgy are rising, as well as in order to decrease an amount of sludge accumulation of abrasive metal processing and level of pollution. The authors [1] developed a process and a comprehensive system of equipment for removing metallic particles from the sludge of abrasive metal treatment. The research of sludge cleaning process of abrasive metal treatment has been made [2]. As a result of the experimental data obtained, the most effective time of sludge cleaning process ( 180 540sec. ) of abrasive metal treatment, when maximum number of oil I-20 passes into the cleaning solution "Labomid", has been defined. Mathematical model of sludge cleaning process of abrasive metal treatment in the cleaning solution "Labomid" has been developed. In mathematical formulation of the problem as a variable the following factors were taken: Ср - concentration of cleaning solution (kg / m3); T - temperature of cleaning solution (оC); - time of sludge cleaning (sec.). Experimental planning technology is used to develop a mathematical model of the number of pollution G f Cp,T, (kg), which is transferred from the sludge abrasive processing of metals in cleaning solution of the above factors used. Composite rotatable plan of the second order for three factors has been realized for response function as a degree second-order polynomial. A mathematical model is represented by the following formula: G 108,03 0,824Cp 0,42T 0,0083 0,0185CpT 0,0001T 0,0084C 2 0,0031T 2 0,0000092 2. The mathematical model of the cleaning sludge process of abrasive metal treatment in the cleaning solution allows to determine the amount of oil that goes into cleaning solution for set-up time limits of cleaning. This will optimize the cleaning process and minimize the overall dimensions (length) of cleaning equipment trough for sludge processing of abrasive metal treatment.
