Description

Technical Field

[0001] The utility model relates to a polymer material recycling and reuse device, in particular to an improvement of a calcium alginate fiber waste recycling and reprocessing device. Background Art

[0002] Alginate is a natural polymer material extracted from brown algae. It is a non-toxic, harmless, biodegradable, pure natural green material. Alginate fiber prepared by wet spinning with alginate as raw material can be used in textile, clothing, medical and health fields. It is a functional fiber material with high added value.

[0003] Calcium alginate fiber is widely used because of its good performance characteristics. It has high moisture regain, good comfort, and excellent hand feel and wearing comfort. It has excellent antibacterial properties, excellent natural flame retardant properties, good hemostasis, moisturizing and wound healing properties, and excellent mildew resistance, mildew resistance level 0, and is renewable and degradable. Seaweed resources are renewable, and seaweed fiber can be naturally biodegraded, will not cause harm to the environment, and fully meets environmental protection requirements.

[0004] However, due to its own characteristics, calcium alginate fiber will inevitably produce waste silk in the spinning process, and this part of the waste silk is difficult to recycle. In addition, calcium alginate fiber itself is relatively expensive, and the waste silk produced in the spinning process is likely to increase the overall cost. Utility Model Content

[0011] The water supply pipe 52 is provided with an adjustment switch 521. The water supply pipe 52 and the adjustment switch 521 can be provided so that when the flushing water pump 5 does not pump enough water from the sodium chloride solution pool 12, the flushing water pump 5 can replenish the water from the flushing pool 11. At the same time, the water supply pipe 52 is controlled by the adjustment switch 521 to ensure that the water supply pipe 52 can be closed when the solution in the sodium chloride solution pool 12 is normal.

[0012] The water inlet end of the water supply pipe 52 is provided with a flushing pool filter basket 522. The flushing pool filter basket 522 can prevent the water supply pipe 52 from sucking the fiber material in the main housing 1 into the flushing water pump 5, thereby ensuring the stable operation of the flushing water pump 5.

[0013] The water inlet end of the return pipe 51 is provided with a sodium chloride solution pool filter basket 511. The sodium chloride solution pool filter basket 511 can prevent the return pipe 51 from sucking the fiber material in the main housing 1 into the flushing water pump 5, thereby ensuring the stable operation of the flushing water pump 5.

[0014] The ultrafiltration membrane 4 is an ultrafiltration membrane-nanofiltration membrane. The ultrafiltration membrane-nanofiltration membrane can highlight sodium alginate and calcium ions.
