Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1, which is a cross-sectional view of a dual-layer protection bag according to a first embodiment of the present invention; as shown in the figure, this embodiment provides a double-deck protection bag 1 for silk membrane equipment, and double-deck protection bag 1 of this embodiment is used for cladding silk membrane structure, when adorning in double-deck protection bag 1's silk membrane structure and stuffing in the baffle, double-deck protection bag 1 can protect the silk membrane structure to avoid producing the friction with the baffle in stuffing the in-process, leads to the silk membrane structure to produce the damage. The double-layered protection bag 1 of the present embodiment includes a protection bag body 10, the protection bag body 10 has a first film layer 101 and a second film layer 102, the first film layer 101 has a first end 101a and a second end 101b, the first end 101a has an opening 103, the second end 101b has a sealing portion 104, that is, the first end 101a of the first film layer 101 does not have an opening as compared with the second end 101b of the first film layer 101, in other words, the opening of the first end 101a of the first film layer 101 is sealed by the sealing portion 104. The second film layer 102 is disposed on the first film layer 101, the first film layer 101 is located on the inner side of the second film layer 102, one end of the second film layer 102 is connected to the second end 101b of the first film layer 101 through hot melting or other methods, the second film layer 102 is separated from the first film layer 101, and a cutting area 105 is formed between the sealing portion 104 and the joint of the second film layer 102 and the first film layer 101. In this embodiment, the material of the first film layer 101 may be the same as or different from the material of the second film layer 102, and in this embodiment, both the first film layer 101 and the second film layer 102 are Polytetrafluoroethylene (PTFE) films. Because the casing or the partition board of the oxygenator is made of Polycarbonate (PC) material and the like, the silk membrane structure is made of polypropylene (PP) hollow fiber membrane and the like, and in order to reduce friction between the protection bag and the partition board and between the protection bag and the silk membrane structure, the protection bag body 10, the first membrane layer 101 and the second membrane layer 102 are made of Polytetrafluoroethylene (PTFE), abbreviated as teflon, and generally called as "non-stick coating". Polytetrafluoroethylene has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. Meanwhile, the polytetrafluoroethylene has the characteristic of high temperature resistance, has extremely low friction coefficient and can be used for lubrication.
Please refer to fig. 2 to 5, which are diagrams illustrating a usage status of the double-layered protection bag according to the first embodiment of the present invention; as shown in the figures, when the double-layer protection bag 1 of the present embodiment is used for assembling the silk-film structure 2, the silk-film structure 2 is firstly placed into the protection bag 10 from the opening 103, and then the tightening member 3 tightens the end of the protection bag 10 having the opening 103. Then, the silk film structure 2 arranged in the double-layer protection bag 1 is compressed by extrusion to reduce the volume of the silk film structure 2, so that the diameter of the silk film structure 2 is smaller than the inner diameter of the partition board 4, the compressed silk film structure 2 is inserted into the partition board 4, the sealing part 104 and one end of the protection bag body 10 with the opening 103 are respectively exposed from two ends of the partition board 4, and the protection bag body 10 is positioned between the silk film structure 2 and the partition board 4. After the silk film structure 2 loaded in the double-layer protection bag 1 is stuffed in the partition board 4, the double-layer protection bag 1 must be drawn out from between the silk film structure 2 and the partition board 4. In this embodiment, the method of withdrawing the double-layered protection bag 1 from between the silk-film structure 2 and the partition 4 is to remove the sealing portion 104, i.e. to cut from the sealing portion 104 and the cutting area 105 between the connection of the second film layer 102 and the first film layer 101, so that the second end 101b of the protection bag 10 has the opening 103, and at the same time, one end of the second film layer 102 at the connection is still connected to the first film layer 101. Then, the tightening member 3 is released, the second film layer 102 is pulled from the first end 101a of the protective bag 10, so that the second film layer 102 drives the first film layer 101 to open relative to the filament-film structure 2, that is, the first film layer 101 is driven by the second film layer 102 and slowly separated from the filament-film structure 2 in a peeling manner, as shown in fig. 6, friction between the first film layer 101 and the filament-film structure 2 is avoided, and the filament-film structure 2 is prevented from being damaged due to the friction.
Please refer to fig. 7, which is a diagram illustrating a usage status of a double-layered protection bag according to a second embodiment of the present invention; as shown in the figures, the dual-layer protection bag 1 of the present embodiment is different from the dual-layer protection bag of the previous embodiment in that the second film 102 protrudes from the first end 101a of the first film 101 relative to the end of the second film 102 connected to the first film 101, in other words, the end of the second film 102 not connected to the first film 101 is not aligned with the first end 101a of the first film 101, when the dual-layer protection bag 1 is withdrawn, a user can easily pull the second film 102 directly, so as to avoid the damage of the silk film structure 2 caused by the friction between the user and the first film 101 when the user pulls the first film 101.
In summary, the invention provides a double-layer protection bag for silk film assembly and a use method thereof.
