Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of membrane filament processing equipment, especially to a membrane filament drying device. BACKGROUND

[0002] In the production process of hollow fiber membranes, the membrane filaments will undergo cleaning and rinsing to remove residual solvents, impurities, and unreacted additives on the surface. These cleaning steps can cause residual moisture or other volatile substances on the surface of the membrane filaments, which can affect the performance and service life of the membranes if not dried. For example, residual moisture can cause the membrane pores to collapse or deform, affecting the permeability and mechanical strength of the membranes, thereby reducing their performance. In addition, drying can ensure the cleanliness and dryness of the membrane filament surface, avoiding swelling or deformation problems caused by water absorption.

[0003] In the prior art, the membrane filaments are dried in a drying rack or an oven, and the airflow (natural wind or drying hot air) can only act on the windward surface, while the leeward surface has poor air flow and slow evaporation of moisture, resulting in uneven drying. Moreover, too fast wind speed can also cause the membrane filaments to fall to the ground, so we propose a membrane filament drying device to solve the above problems. SUMMARY

[0004] The utility model discloses a membrane filament drying device to solve the shortcomings in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] Preferably, the anti-slip assembly comprises a plurality of round sleeves, the inner walls of the plurality of round sleeves are threadedly connected with the outer wall of the cross placement rack, the outer walls of the plurality of round sleeves are fixedly provided with convex rings, the outer walls of the plurality of convex rings are rotatably provided with annular rings, the top of the plurality of annular rings is fixedly connected with anti-slip rods, and the membrane filaments are limited by the anti-slip assembly to prevent them from sliding out of the cross placement rack.

[0008] Preferably, a handle is fixedly connected to the outer wall of the metal mesh door, and the metal mesh door is in contact with the plurality of activated carbon filter screens. The handle is used to drive the metal mesh door to rotate outward.

[0009] Preferably, the outer wall of the enclosure is hinged with two sealed doors, and existing door locks are installed between the two sealed doors and the metal mesh door and the enclosure.

[0010] Preferably, the bottom of the base plate is fixedly connected to four self-locking wheels, the bottom of which is in contact with the inner wall of the box. The base plate moves through the four self-locking wheels and is fixed in position by the mechanical self-locking structure on the self-locking wheels.

[0011] Preferably, the bottom of the turntable is rotatably connected to the top of the base plate.

[0012] Preferably, the inner wall of the inner frame is fixedly connected with a partition, which divides the inner frame into two areas.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution uses a motor-driven turntable to rotate the cross-shaped placement frame, periodically exposing each surface of the membrane fibers to the airflow, thus completely solving the problem of uneven drying in traditional fixed drying methods.

[0015] The height and horizontal position of the anti-slip bar can be adjusted flexibly to prevent the membrane fibers from falling off due to high-speed airflow and to avoid mechanical damage caused by rigid fixation, thus balancing safety and ease of operation.

[0016] Activated carbon filters remove moisture, particulate matter, and organic pollutants from the air, fundamentally eliminating the risk of secondary pollution and ensuring the cleanliness of the membrane fiber surface. Attached Figure Description
