Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Examples

Referring to fig. 1-4, a hollow fiber curtain type membrane package membrane shell according to a preferred embodiment of the present invention includes a shell 1, and the cross section of the shell 1 is rectangular. The shell 1 is provided with a bottom plate and an opening opposite to the bottom plate, a plurality of partition plates 10 are arranged in the shell 1, each partition plate 10 is vertically connected with the bottom plate, and the partition plates 10 divide the shell 1 into a plurality of slit areas. The ratio of the pitch of each partition plate 10 (i.e., the width of the slit region) to the outer diameter of the hollow fiber membrane filaments is 1-2: 1. In order to increase the packing density of the hollow fiber membrane filaments, the width of the slit region should be as small as possible on the premise that the width is larger than the outer diameter of the hollow fiber membrane filaments. The height of the partition plate 10 is 3/4 of the height of the entire housing 1.

The length of the partition board 10 is the same as the inner diameter of the shell 1, the cross section of the partition board is in a comb shape, after the partition board 10 and the partition board are both filled in the shell 1, the comb teeth 20 on the partition board are perpendicular to the partition board 10 and are in contact with the partition board 10, the slit area is divided into a plurality of subareas 100 by the comb teeth 20, and each subarea 100 is used for filling hollow fiber membrane filaments. The distance between the teeth 20 is as small as possible when it is larger than the outer diameter of a single hollow fiber membrane filament. The height of the comb teeth 20 is 1/4 of the height of the housing 1. The sum of the height of the slit area and the height of the comb teeth 20 is equal to the height of the housing 1.

The shell 1 is also filled with sealant. The inner wall of the shell 1 is provided with a plurality of guide grooves 11, and the guide grooves 11 extend along the height direction of the shell 1 and are in sliding fit with the comb teeth 20.

Use the utility model discloses the time, before the sealant is sealed, at first with the leading-in slit district to casing 1 of hollow fiber membrane silk, form vertical one-tenth piece membrane silk, the radical of hollow fiber membrane silk is the same with the channel number that shown broach 20 formed in figure 2 in every slit. Then, the membrane filaments in the slit regions of the shell 1 are transversely separated by using the partition plates shown in fig. 2, so that the hollow fiber membrane filaments in each slit region sequentially enter the corresponding channels, and the partition plates are filled in the shell 1. As shown in fig. 3, when the inner wall of the housing 1 is provided with the guide groove 11, the partition board can be pushed along the guide groove 11, and the guide groove 11 plays a guiding role to prevent the partition board from deviating from the track. Thus, under the separation action of the partition plate 10 and the partition plate in the shell 1, each hollow fiber membrane wire is independent and has a certain uniform distance. Finally, the sealing glue is filled into the shell 1 and shaped, all the hollow fiber membrane filaments are fixed, and the schematic plan view of the assembled hollow fiber curtain type membrane packaging membrane shell is shown in fig. 4.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
