Problems solved by technology

But at the same time, it brings new requirements to the production process, especially the gluing process, which poses challenges for the large-scale production of this new membrane element.
In addition, the existing complex end surface sealing process also leads to uneven glue application, resulting in a lot of waste of glue, which is not conducive to quality control

Embodiment 1

[0067] The sealing process is as follows:

[0068] Lift up the gland; use adhesive tape to form a plastic cup on the end face of the pre-cut coiled membrane element (the pre-trimmed size of the groove side is 12mm, and the pre-trimmed size of the sealing ring side is 24mm), and the depth of the glue cup is 2 -20mm; use the sealing ring to form a sealed space on the end face of the spiral membrane element; on the side of the groove, apply 14 grams of glue ( UK 178A / B, purchased from Henkel (Henkel)) was poured into the plastic cup, spread evenly in the plastic cup by shaking, applying compressed air to the plastic cup and maintaining the pressure at 5 bars for 30 seconds; supplemented with 13 grams of glue , Spread it evenly in the plastic cup by oscillating, apply compressed air to the plastic cup and maintain the pressure at 5 bar for 40 seconds; add 9 grams of glue, spread it evenly in the plastic cup by oscillating, and apply it to the plastic cup Compress the air and m...

Abstract

The invention relates to a glue sealing method and device. The glue sealing method comprises the following steps that the end face of a spiral-wound membrane element is coated with glue, wherein the spiral-wound membrane element comprises at least one water-inlet channel and at least one water-production channel, and openings are formed in the end faces of the water-inlet channels and the water-production channels; and then the glue is pushed into the water-inlet channels and the water-production channels of the spiral-wound membrane element, wherein the distance of the glue entering the water-inlet channels is longer than the distance of the glue entering the water-production channels. The glue sealing device comprises a glue applicator and a pressure device; the glue applicator is used for coating the end face of the spiral-wound membrane element with the glue, the spiral-wound membrane element comprises the water-inlet channels and the water-production channels, and the openings are formed in the end faces of the water-inlet channels and the water-production channels; and the pressure device is used for exerting pressure on the glue so as to press the glue into the water-inlet channels and the water-production channels of the spiral-wound membrane element.

Description

technical field [0001] The invention relates to a glue sealing method and equipment, in particular to a glue sealing method and equipment for the end face of a roll-type membrane element with lateral water production flow. Background technique [0002] As a new type of spiral membrane element, the lateral water flow type spiral membrane element makes the water flow spirally to the central tube, and the product water flows out from both ends. It has the characteristics of long flow process, high recovery rate and low back pressure of product water. Features, will greatly improve the performance of water treatment equipment. But at the same time, it brings new requirements to the production process, especially the gluing process, which poses challenges for the large-scale production of this new membrane element. In addition, the existing complex end surface sealing process also leads to uneven glue application, resulting in a lot of waste of glue, which is not conducive to qu...
