Embodiment Construction
[0042] Attached to the following Figure 1-7 This application will be described in further detail.
[0043] The embodiment of the present application discloses a cleaning method for a spinning assembly, which includes the following process steps:
[0044] S1, disassemble the feed cover, deflector, distribution plate and spinneret in turn in the spinning assembly and cool each spinning assembly. After each spinning assembly is cooled to room temperature, remove the feeding cover, guide The flow plate, distribution plate and spinneret are loaded into the cleaning device and ultrasonically cleaned with cleaning liquid. The number of ultrasonic cleaning is controlled to be 1 to 3 times (it can be adjusted according to the cleaning effect of each spinning component), and the ultrasonic cleaning temperature The temperature is controlled at 50-65°C, the time of each ultrasonic cleaning is controlled at 15-25 minutes, and the ultrasonic frequency is controlled at 35-130Hz;

The invention relates to the technical field of spinning assembly cleaning, in particular to a spinning assembly cleaning method which comprises the following process steps that S1, a spinning assembly is sequentially detached and cooled, and after the spinning assembly is cooled to the room temperature, a feeding cover, a flow guide plate, a distribution plate and a spinneret plate are subjected to ultrasonic cleaning through cleaning liquid; s2, after cleaning is completed, the feeding cover, the flow guide plate, the distribution plate and the spinneret plate are dried; and S3, the dried feeding cover, the dried flow guide plate, the dried distribution plate and the dried spinneret plate are subjected to gas purging, after purging is completed, the feeding cover, the flow guide plate, the distribution plate and the spinneret plate are assembled, and cleaning is completed. Polyethylene fibers, white oil and the like remaining on the surface of the spinning assembly can be fully dissolved, and the white oil can be recycled by conducting aftertreatment on the cleaning solution; compared with a calcination method, the method has the advantages that the cleaning period is greatly shortened, the energy consumption required for cleaning the spinning assembly is reduced, and meanwhile, possible destructive damage to the spinning assembly caused by the calcination method is avoided.
Description
technical field [0001] The present application relates to the technical field of cleaning of spinning assemblies, and in particular, to a cleaning method of spinning assemblies. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber, also known as high-strength and high-modulus polyethylene fiber, is a high-performance fiber developed in 1970 with a white appearance. Large high-performance fibers. Because UHMWPE fiber has excellent properties such as high strength, high modulus, low density, impact resistance, and chemical corrosion resistance, UHMWPE fiber is widely used in lightweight bulletproof helmets, soft bulletproof clothing, etc. field. [0003] In the related art, the preparation process of ultra-high molecular weight polyethylene fiber includes the following process steps: preparing spinning solution-adding antioxidant-extrusion spinning by twin-screw extruder-quenching in cold water bath to form frozen collagen fiber-extraction so...
