Abstract
Description
technical field
[0001] The invention belongs to the field of spinning detection, in particular to a novel spinneret washing process. Background technique
[0002] The nozzle assembly replaced from the spinning machine needs to be sent to the inside and outside for precise cleaning. The existing nozzle washing technology has the following defects: 1. The labor intensity of the employees is high. 2. Great damage to the nozzle. 3. High labor costs. 4. The production cost is high.
[0003] Existing patents such as the application number: CN201420726344.6, the invention patent named "Spinning Cleaning System for Hollow Fiber Membranes", its technical solution is: the invention provides a high-efficiency hollow fiber membrane spinner cleaning system , which has: a silk slurry supply tank, which supplies silk slurry as a material of the hollow fiber membrane; a spinneret, which is connected with the silk slurry supply tank, and sprays the silk slurry supplied by the silk slurry ...
Examples
Embodiment 1
[0044] A novel spinneret washing process is characterized in that: the specific steps are as follows:
[0045] The first step, lye spray washing;
[0046] The second step, hot water spray washing;
[0047] The third step, hot water spray washing;
[0048] The fourth step; cut water;
[0049] The fifth step, pickling;
[0050] The sixth step, lye spray washing;
[0051] The seventh step, hot water spray washing;
[0052] The eighth step, hot water spray washing;
[0053] The ninth step, cut the water;
[0054] The tenth step, drying.
[0055] The lye spraying in the first step and the sixth step is specifically to continuously clean the spinneret after the lye is filtered, the spraying pressure is 1.2-1.7kgf, the working temperature is 40-50°C, and the filtration is 80-120 filter.
[0056] The hot water spray washing in the second and seventh steps is specifically to continuously clean the spinneret after the water is filtered, the spray washing pressure is 1.2-1.7kgf,...
Embodiment 2
[0062] The first step is lye spraying; after the lye is filtered, the spinneret is continuously cleaned, the spraying pressure is 1.5kgf, the working temperature is 40-50°C, and the filtration is specifically 100 mesh filtration.
[0063] The second step is hot water spray washing; after the water is filtered, the spinneret is continuously cleaned, the spray washing pressure is 1.5kgf, the working temperature is 50-60°C, and the filtration is specifically 100 mesh filtration.
