Abstract

The invention relates to an ultrafiltration membrane module end-seal casting method, which comprises the following steps of: fixing an ultrafiltration membrane module to be cast by using a membrane module fixing device, pouring end-seal glue into a casting sleeve, pushing the casting sleeve containing the end-seal glue at a rate of 3-10mm / min upwards so as to make the end-seal glue contact an end membrane filament of the ultrafiltration membrane module; and taking down the ultrafiltration membrane module and standing for solidification. The invention correspondingly provides ultrafiltration membrane module end-seal casting equipment employing the method. The equipment comprises a membrane module fixing device for fixing the ultrafiltration membrane module, a casting sleeve for containing the end-seal glue below the membrane module fixing device, and a hydraulic device for bearing the casting sleeve to move up and down. By a surface glue feeding method, the ultrafiltration membrane module is subjected to end-seal casting, the problem that flue flows insufficiently in the conventional static casting is solved, complete filling is realized, the casting quality is stable, the operation is simple, and power machines are not needed to be used.

Description

technical field [0001] The invention relates to the end-sealing technology of membrane modules, and more specifically, to an ultrafiltration membrane module end-sealing casting method and casting equipment. Background technique [0002] Ultrafiltration membrane is a filter material for water treatment, and the shape of the membrane is mostly hollow fiber. The hollow fiber membrane module is cylindrical, and both ends need to be sealed with glue, so that the membrane filament and the shell can be integrated to ensure airtightness and firmness. The glue used for casting is usually epoxy resin glue. Since the membrane filament is a polymer material, it is generally not resistant to high temperature, so the epoxy resin glue used is usually room temperature curing glue. [0003] In the field of casting of hollow fiber membranes, the centrifugal casting method is traditionally used. In this method, the membrane module to be poured is fixed horizontally on the centrifugal pouring...
