Problems solved by technology

Due to the large number of hollow fiber membranes and the large amount of epoxy resin casting, through the existing technology, the method of manually hammering the hollow fiber membrane elements on the wooden board or using the cam to roll up and down can not only statically cast the epoxy resin layer Soft and uneven, and the mechanical wear of the membrane components is large, and the working environment is very noisy

Embodiment

[0012] The process steps for realizing the static casting of the membrane element in this embodiment are as follows: first select the static casting device for the membrane element, assemble the membrane element 16 on the fixed ring 2 of the membrane shell, and tighten it with a clamp; Connect with the glue injection pot 10, and tie it tightly with a woolen rope or silk thread to ensure that it does not leak; then pour the epoxy resin with a good ratio into the glue injection pot 10, and firmly plug the rubber plug 15; turn on the power, open the compression The air system 13 allows compressed air to enter the glue injection pot 10 through the compressed air pipe 14, and the epoxy resin is slowly pressed to the glue injection nozzle 11 at the lower end of the membrane element 16 along the glue injection pipe 12, and then injected into the inside of the membrane element 16, The glue injection speed is 50-80mL / min; after all membrane elements 16 are glued and confirmed to be corr...

Abstract

The invention belongs to the technical field of casting of rubber and plastic material membrane elements, and relates to a technical process method for statically casting a membrane element. The method comprises the following steps of: assembling the membrane element onto a membrane shell fixing ring by using a membrane element static casting device, and tightly clamping by using a hoop; communicating a glue injection nozzle with a glue injection kettle by using a glue injection pipe, and fastening by using a broken filament rope or a filament wire; pouring epoxy resin into the glue injection kettle, and stuffing up a rubber stopper by exerting force; and making compressed air pass through a compressed air pipe to enter the glue injection kettle, slowly pressing the epoxy resin into the glue injection nozzle at the lower end of the membrane element along the glue injection pipe, injecting into the membrane element, statically solidifying, and then casting the other end of the membrane element according to the same process to form a product. The method has the advantages that: the process is simple, the principle is reliable, the automation degree is high, the casting effect is good, the static casting time is short, work load is low, labor cost is saved, production efficiency is high, the mechanical abrasion degree of the membrane element is low and working environment is friendly.

Description

Technical field: [0001] The invention belongs to the technical field of rubber-plastic material membrane element casting, and relates to a static casting technology method for membrane elements, in particular to a static casting epoxy resin layer film, which realizes its dense structure, uniform thickness and friendly casting environment. Background technique: [0002] At present, when making hollow fiber membrane elements, it is necessary to perform static casting on both ends of several hollow fiber membranes, so as to consolidate the effect of centrifugal casting, and at the same time avoid the broken wires at the casting ends of the membrane elements during the operation of the membrane elements. Due to the large number of hollow fiber membranes and the large amount of epoxy resin casting, through the existing technology, the method of manually hammering the hollow fiber membrane elements on the wooden board or using the cam to roll up and down can not only statically cas...
