Description

TECHNICAL FIELD

[0001] The utility model relates to a membrane filament frame mainly for the silk distribution of hollow fiber membrane module. BACKGROUND

[0002] Hollow fiber bundle membrane filaments need to be distributed by a silk distribution frame during packaging to increase the stability of the module. However, the silk distribution frames commonly used on the market have the following defects: first, the structure is complex and needs to be assembled by multiple parts, which increases the material and labor costs; second, the size of the silk distribution frame is designed to be too bulky, which undoubtedly greatly reduces the silk filling amount of the module, thereby affecting the effective area and water production capacity of the membrane module; third, the existing silk distribution frames on the market are mostly used in hollow fiber ultrafiltration membrane modules, and the structure design of this type of silk distribution frame is not suitable for hollow fiber RO membrane modules. Therefore, developing a suitable silk distribution frame for the membrane module is a hot topic for many manufacturers.

[0003] The existing patent (application number: CN202121852247.8) discloses a column type hollow fiber membrane pouring device, which is provided with a support, and a hollow fiber membrane filament is hung on the support. The hollow fiber membrane filament is placed in a membrane shell, and the membrane shell is fixed on the support. The bottom of the membrane shell is provided with a pouring tray, and the bottom of the pouring tray is provided with a first glue inlet and a second glue inlet. A plurality of first and second shunt pipelines are arranged in the pouring tray, and the first and second glue inlets are connected with the first and second shunt pipelines, respectively. In addition, a plurality of shunt pipeline outlets are provided, so that the adhesive enters the membrane module from multiple points through the first and second glue inlets, thereby improving the distribution speed of the adhesive and the glue pouring efficiency. The adhesive is evenly laid on the end face of the pouring tray, avoiding uneven distribution and unevenness of the adhesive. In addition, an aeration hole reservation pipe is arranged on the end face of the pouring tray, and an aeration hole is formed after pouring to clean the membrane filament. However, it is difficult to effectively remove the remaining air bubbles in the device by gravity flow pouring. SUMMARY
