Problems solved by technology

[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 cost of employment
4. High production cost
[0004] In the process of washing the spinneret in the above patent, due to the effect of pressure, the spinneret will still be greatly damaged

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.

[0064] The third 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 50 mesh filtration.

[0065] The fourth step: cut water; under normal temperature, use air to spray the spinneret continuously, and the spray pressure is 3523Pa.

[0066] The fifth step, pickling; at room temperature, use concentrated H 2 SO 4 The solution washes the spinneret c...

Abstract

The invention belongs to the spinning detection field, and particularly relates to a novel spinning head washing technology. The novel spinning head washing technology includes the concrete steps of: 1, alkaline liquid spray washing; 2, hot water spray washing; 3, hot water spray washing; 4, air spray washing; 5, acid pickling; 6, alkaline liquid spray washing; 7, hot water spray washing; 8, hot water spray washing; 9, air spray washing; and 10, drying. The above technical processes realize automation except the beginning manual material-loading and the final manual material-discharging and assembling. At the same time, a process of supersonic wave washing is not needed. Two-stage filtration is adopted in a reservoir, so that clean washing is guaranteed and a nozzle is prevented from being blocked. The continuous washing is realized. Unclean matters on the outer surface of a spinning head are removed, and the spinning head is not damaged.

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.
