The research work of a submersible washing machine with fluid activation by air bubbling from the outside of the laundered objects

Abstract

The research aimed at improving the process of washing filled cylindrical cans in the production of tin cans is very relevant and of great importance in the food industry. So, a new two-section washing machine design is proposed. Tests performed at the machine under consideration. The results of experimental studies of the quality of surface cleaning metal cans were presented. The optimum operating mode of the washing machine was determined. The minimum energy consumption of the machine is Emin = 69·10-3 W·h / pcs at the optimal driving wheel speed nopt = 31 min-1. For comparison - for analogs the minimum energy intensity is Emin = 200·10-3 W·h / pcs. As a result of experimental studies, it has been established that for the qualitative cleaning of the surface of filled cans, which corresponds to the requirements of the standard, the rotational speed of the drive wheel nopt = 31 min-1, temperature t = 74 … 85 ° C and concentration of the washing solution c = 1.7… 3 g / l. When the capacity of the washing machine is increased to 100 pcs / min. it is required to increase nopt = 31 min-1 to nmax = 35 min- 1, with c = 1.7 g / l and the temperature of the washing solution t = 72 … 85 ° C. At the same time, energy intensity increases by only 2%. The design features of the developed washing machine allow to reduce the power consumption of the cleaning process, and the productivity can be increased without loss of quality of cleaning the cans in comparison with existing washing machines.
