Description

Technical Field

[0001] The utility model belongs to the technical field related to spandex production, and particularly relates to an automatic environmentally friendly cleaning device for a heat preservation table. Background Art

[0002] Dry spinning is also called dry solution spinning. The production process is divided into three parts: prepolymerization, chain extension and spinning. The spinning solution is extruded by spinning metering under hot air flow and then sprayed from the insulation table. The solvent evaporates at a higher temperature and the solute solidifies before winding. Dry spinning is the most commonly used method in spandex production. About 80% of spandex is spun by this method. The internal structure of the insulation table is complex and difficult to clean. Among them, the functions of uniform distribution and efficient heat exchange are the basis for ensuring the spinning index. Due to its harsh working environment, as the use time increases, the stock solution adheres to the inner wall of the insulation table, affecting the product quality. In order to meet the spinning index, the insulation table needs to be cleaned regularly. The current cleaning method is mainly to soak in water after disassembly, solidify the stock solution in water, and then clean it manually, but it still has the following disadvantages in actual use:

[0003] It takes two days to clean and assemble a warming table. During the dismantling and cleaning process, DMAC gas will evaporate and pollute the air. At the same time, the water produced by cleaning and the solid waste produced by soaking in water must be disposed of in compliance with regulations, which increases environmental protection costs.

[0004] During the cleaning process of the insulation table, DMAC is input twice for cleaning. However, when working, the DMAC cleaned twice is directly discharged into the recovery equipment, which not only increases the pressure of the DMAC recovery equipment, but also the cleanliness of the DMAC cleaned twice is higher, and the recovery equipment consumes more energy.
