Textile Rope Dyeing Automation/ Troubleshooting

 



TEXTILE ROPE DYEING AUTOMATION / TROUBLESHOOTING

How to retrofit the current Rope Dyeing  processing line to increase the maximum yield with minimum rejection and maximum efficiency?



This report aims to provide the details of introducing a dosing pump and the hydro feeder in the current 3 in 1 circulation line for getting efficient and uniform (without variation) dyed product, it is observed that the current line lacks the proper feeding system which is disturbing the consistency of shade at some place, in this report three types of designed are given for making an efficient dyeing line to resolve this problem. 

INTRODUCTION

The purpose of the report is to recommend the installation of dosing pump and hydro feeder for minimizing the variations. Because the current line has no such components and for fulfilling their requirements the mobile pumps are used as alternatives  which are not functioning efficiently.

 

PROBLEMS ASSOCIATED WITH CURRENT DESIGN 

       The mobile pumps didn’t have the proper stirring system which restricts the chemical to mix properly as a result of which the denser chemical settled down at the bottom.

       They also don’t have the leveling system which increases the chances of making incorrect level.

       The denser chemicals which settled down are sometime accumulate with in the pipe and as a result of which the pump get choked.

       Mobile pumps not fulfill the basic requirement of more than 7 liters and also not worked properly at limited feeding of > 1.

       Whereas for the continual feeding of dye, topping pump is used whose head is at a far distance from the box, which generates the heat for maintaining such a high pressure and might be get stop in the future long production runs. 

RECOMMENDATIONS

The above issues could be resolved by making some alteration in the current line, and for this three type of design are given below that could solve this problem.

DESIGN 2

 

 

DESIGN 3



CONCLUSION

By selecting one of the three  above designs the system could be perform better then present, the sedimentation will not occur because of the introduction of  hydro feeding system which is directly attached with the main circulation line of the box. Besides this the installation of dosing pump in the 3 in 1 tank allows the continual flow of dye at constant rate without making any of the high heat loses, because of the low head distance and this pump will also be used for high feeding . Moreover, the topping pump could be used for the caustic feeding to completely eliminate the mobile pump from the line.
