Overflow Dyeing Machine Temperature Field Analysis And Circulation System Optimization

Overflow dyeing machine exists several problems in working process, such as the localtemperature difference and the temperature of the system imbalance, which resulting inuneven dyeing quality of fabrics; due to lack of the heat transfer system reference data,which does not understand the status of the dyeing machine heat loss; in addition, the bodyheat preservation effect is not ideal, which cause more energy consumption. The problemexists, which makes the study of temperature field and dyeing machine to improve insulationperformance becomes urgent.Overflow dyeing machine the machine temperature field as the research object, based onSolidworks software to establish three-dimensional model of the overflow dyeing machine,according to the experimental test and dyeing technological conditions, establish the dyeingmachine temperature boundary conditions, using the Fluent software to simulate dyeingmachine temperature field is obtained. According to the theory of heat transfer temperaturefield analysis of dyeing machine, finds out the factors lead to dyeing machine heat dissipation.Stationing way based on state space, the dyeing machine body of the various surfaces ofthe heat source, the body temperature and environmental temperature on the comprehensivetesting and analysis of the distribution. Test results show that the uneven distribution ofvarious structures and equipment of heat in the body, away from heat and dyed clothaccumulation place, the body surface temperature is higher than other places, the body’ssurface temperature range between84.32℃~89.75℃.The body’s surface temperature measured and simulated values were analyzed, resultsshowed that the simulated values and measured values2.05℃, the maximum of absolutevalue of error is only6%of the measuring point. The simulation results are in good agreementwith the experimental results, the simulation method can be reference and use. Heat allocationand spending on dyeing process, dyeing machine cooling is analyzed form, dyeing machinethermal equilibrium equation is established, and tested for heat loss calculation and analysisand evaluation.Based on in dyeing process heat transfer theory and numerical simulation, proposed thefeasible dyeing machine body surface heat preservation structure scheme. Using Fluent software to simulate the thermal insulation installation under the structure of dyeing process,and dyeing process with no insulation device temperature curve comparison. Results showthat the insulation scheme can very good reduce heat dissipation to the plant through the bodysurface, make the body’s internal temperature remains uniform time prolong and reduceenergy consumption, optimizing the circulation system, better thermal insulation effect.Finally, using the rubber sponge and rock wool insulation heat preservation heat preservationmaterial is tested. Experimental results and simulation analysis, in order to verify thefeasibility of thermal insulation solutions.
