Description
Technical Field
The invention belongs to the field of membrane separation, and particularly relates to a shell structure.
Background
The hollow fiber membrane separation device generally comprises a cylindrical shell, a hollow fiber bundle, a sealing layer and two end covers, wherein the cylindrical shell is mostly made of polypropylene materials for environmental protection and safe use. The membrane separation device is a pipeline and a container for solute exchange of two fluids, the membrane separation device is divided into two flowing spaces through the structure, the hollow fiber bundle is placed in the cylindrical shell, two sides of the hollow fiber bundle are sealed by non-toxic pouring sealant and fixed with the shell, the opening of the hollow fiber is arranged outside the sealing layer, the outer end of the hollow fiber bundle is sealed by end covers at two ends to form a first fluid channel, and a gap between the outer layer of the fiber bundle and the shell forms a second fluid channel.
In the processing process of the membrane separation device, the sealing and fixing of the hollow fiber bundle and the shell are the key process of the processing of the membrane separation device, and as the pouring sealant can shrink to a certain extent when being cured and sealed, in order to prevent the sealed part from generating larger stress, the two ends of the shell are required to be provided with flexible sheets which are circumferentially separated and arranged, and one part of the top ends of the flexible sheets is embedded into the sealing layer, so that the sealing is realized and larger stress concentration can not be generated.
Although the stress problem is solved by the flexible sheets which are arranged in a circumferential separation manner, when the hollow fiber bundle is sealed with the shell, the nontoxic pouring sealant cannot be well hung on the part to be sealed, namely the pouring sealant has the risk of falling off, the sealing effect is poor, the processing defective rate is high, and the like. Through carrying out plasma treatment to the flexible sheet surface, can reduce the risk that the casting glue drops, but increased extra operation like this, increased the processing degree of difficulty of product, processing cost improves to some extent.
To reduce the resistance of the liquid and at the same time facilitate a more uniform contact of the potting compound with the flexible sheet, people often set the flexible sheet to a smooth surface. The flexible sheet has a smooth surface, and is beneficial to the design of a mould and the demoulding treatment in the production process.

The following disclosure provides many different embodiments, or examples, for implementing different aspects of the invention.
Referring to fig. 1-8, a shell structure comprises a cylindrical main body 1, wherein flexible sheets 2 are arranged at two ends of the main body 1 in a circumferentially spaced manner, and at least part of the flexible sheets 2 is provided with a concave-convex structure 3.
In some examples of the housing structure, a height difference between upper and lower surfaces of the concavo-convex structure is greater than 0 and not more than 5 mm. The data show that the sealant can be prepared by one-step demolding of the mold conveniently under the height difference, and the sealant can be well hung.
In some examples of housing structures, the relief structure is a continuous groove or protrusion, forming a thread. Therefore, the pouring sealant can form threads in the concave-convex structure, and the combination is tighter.
In some examples of the housing structure, the concave-convex structure is a concave-convex structure, and the concave-convex structure is arranged regularly or irregularly.
In some examples of the shell structure, the concave-convex structure is a concave hole or convex point structure, and the circle center distance between adjacent concave holes or convex points is 1-20 mm. The circle center distance can be correspondingly adjusted as required, such as 1-15 mm, 1-10 mm, 2-15mm, 2-12 mm and the like.
In some examples of the shell structure, the relief structure is a frosted surface. Therefore, the contact area between the pouring sealant and the flexible sheet can be increased, the frosted surface is easy to prepare, and the flexible sheet can be demoulded once, so that the production cost is reduced.
In some embodiments of the housing structure, the total area of the relief structure is 10-60%, preferably 20-60%, 30-60% of the total area of the flexible sheet.
In some examples of housing structures, the top end of the flexible sheet 2 is provided with a bifurcation 21. Through the arrangement of the fork, the top end part of the flexible sheet can be bent and deformed more easily, and the stress generated during the curing of the pouring sealant can be reduced more favorably.
In some examples of the shell structure, the width of the flexible sheet close to one end of the main body is larger than the width of the flexible sheet far away from one end of the main body, and the inclined design can facilitate the demolding of the shell during injection molding and processing, and meanwhile, the top end part of the flexible sheet can be bent and deformed more easily, so that the stress generated during the curing of the pouring sealant can be reduced more favorably.
The distance between the flexible sheets can be correspondingly adjusted according to the size of the cylindrical main body so as to meet the requirements of shell structures with different sizes. In some embodiments of the housing structure, the flexible sheets have a pitch of 0 to 20mm, 1 to 15mm, 1 to 10 mm.
In some examples of the housing structure, the total number of the flexible sheets at one end of the cylindrical body 1 is 18. Data show that the 18 flexible sheets can ensure the mechanical strength of two ends of the shell, ensure that the shell cannot deform when being connected and sealed, and ensure that the flexible sheets are not easy to break.
In some examples of housing structures, the spacing between the prongs 21 of the same flexible sheet 2 is 0 to 10 mm.
In some case structure examples, at least one side of the bifurcation 21 is provided with the concavo-convex structure 3. In some examples of the housing structure, the relief structure 3 is distributed on at least one side of the flexible sheet 2. Therefore, the contact area between the pouring sealant and the concave-convex structure can be increased, and the adverse effect on the flow of liquid caused by the further flow of the pouring sealant to the lower end of the flexible sheet can be reduced or even avoided.
In some examples of the housing structure, the relief structure 3 is distributed on the surface and/or side of the flexible sheet 2.
In some examples of the housing structure, an end of the flexible sheet near the main body is a smooth surface. One end of the flexible sheet close to the main body forms a flow channel which is a smooth surface, so that the resistance of fluid flow is reduced, and the subsequent use is facilitated.
The free end of the flexible sheet is the main curing area of the potting adhesive, and in some examples of the housing structure, the relief structure is distributed at the free end of the flexible sheet. Therefore, the glue can be better hung, and the pouring glue is prevented from flowing downwards to the end of the cylindrical main body.
In some examples of the shell structure, the shell structure is made of a thermoplastic.
In some examples of housing structures, the thermoplastic is polypropylene.
Example 1:
a shell structure comprises a cylindrical main body 1, wherein the diameter of the cylindrical main body 1 is 32-44mm, the length of the cylindrical main body 1 is 250-280 mm, 18 flexible sheets 2 which are circumferentially arranged at two ends of the main body 1 in a spaced mode are arranged at two ends of the main body 1, the length of each flexible sheet 2 is 10-40 mm, the width of the bottom end of each flexible sheet 2 is 2-15mm, symmetrical bifurcations 21 are arranged at the positions of the flexible sheets 1/2, concave-convex structures 3 are arranged on the outer edges of the bifurcations 21, and the height difference between the upper surfaces and the lower surfaces of the concave-convex structures 3 is 0-3 mm.
The foregoing is a more detailed description of the invention and is not to be taken in a limiting sense. It will be apparent to those skilled in the art that simple deductions or substitutions without departing from the spirit of the invention are within the scope of the invention.
