Flow Field And Structural Analysis Of Overflow Dyeing Machine And Its Energy Saving Design

Overflow dyeing machine has wide adaptability, good dyeing effect, bath ratio, etc. Theyare widely used in cotton, cotton fiber, blended yarn and chemical fiber fabric dyeing process.With the development of society, energy saving, consumption reduction, emission reductionas the main direction of development of overflow dyeing machine, and its related technologyresearch has become a hot research of overflow dyeing machine. In this paper, aiming at theoverflow dyeing machine temperature imbalance, heat dissipating capacity larger issues,through the overflow dyeing machine flow field, temperature field simulation analysis,guidance and completed technology research body shell insulation. Specific studies are asfollows:According to the dyeing process and the process of overflow dyeing machine, throughthe analysis of the fluid flow model, the RNGk-ε turbulence model as the overflow dyeingmachine flow model, choose the flow equation of gas-liquid two-phase as overflow dyeingprocess equation of flow field analysis;Establish the overflow channel model was examined by using3D drawing softwareSolidworks, the three-dimensional model is imported into Fluent mesh and calculation ofgeometric model. In the Fluent calculation according to the parameters of overflow dyeingmachine working parameters in the actual production of boundary conditions and solutioncalculation; and according to the actual dye flow parameters in dyeing process and flow state,establish mathematical model of overflow dyeing machine. Finally, after treatment withFluent, the analysis results of flow field and temperature field of the dyeing machine. Throughthe analysis of the flow field simulation results of dyeing machine, dyeing machine todetermine the flow channel on the distribution of the temperature field is discussed;The overflow dyeing machine temperature field simulation results were analyzed todetermine the surface temperature distribution, dyeing machine dyeing machine shell;temperature measurement of body surface of the shell and the workshop using temperaturetesting instrument, through the simulation analysis results and actual test data, it shows thatthe simulation results can reflect the actual production, and proved to be effective analysis andSimulation of temperature field. Therefore, the simulation resu. Therefore, the simulation results of temperature field of overflow dyeing machine, can guide the completion ofenergy-saving design of body structure.Analysis of the structure of flow field and temperature field of dyeing machine throughthe overflow, determine the overflow dyeing machine shell energy-saving design scheme,namely rock wool and rubber sponge composite insulation energy-saving structure form, andthe energy saving and the corresponding structure design; in addition to take temperature fieldfor energy saving design of the simulation, the measured data are basically consistent with thesimulation results, verify the effectiveness of energy-saving design.
