Problems solved by technology

In industrial applications, leakage often occurs due to loose fit
Moreover, once the water pressure suddenly increases, this physical seal will fail, resulting in waterlogging
In long-term use, the membrane stack will also leak due to aging and deformation of the material
At the same time, th...

Abstract

The invention relates to the technical field of household appliances and specifically relates to an EDR (Enhanced Data Rate) membrane stack and a method for sealing the EDR membrane stack. The EDR membrane stack comprises a plurality of membranes and runner separating plates (the membranes and the runner separating plates are alternatively overlapped so as to form the EDR membrane stack). The sealing method comprises the following steps: coating glues on peripheries of the membranes or separating plates, and then successively overlapping and assembling, and successively bonding the membranes and the runner separating plates, thereby acquiring an initial EDR membrane stack; or splicing the membranes and the separating plates in turn in the manner of ultrasonically welding; or placing the EDR membrane stack into a sealing box, filling the sealing box with the glue, thereby acquiring the final EDR membrane stack; or wrapping fibers or other reinforcing materials on the periphery of the EDR membrane stack, and then coating the glue for curing and sealing. The steps of the method can be separately adopted and also can be adopted in turn. The final EDR membrane stack is reinforced with the glue, so that the membranes are more firmly spliced, without gaps, and the EDR membrane stack can withstand the pressure above 0.8MPa and is watertight after long-term use.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for sealing an EDR membrane stack and the EDR membrane stack. Background technique [0002] The EDR membrane stack is an important component in the water purifier. When the pipe network tap water flows into the water purifier, it will bring a certain pressure shock to the components in the EDR membrane stack (especially in areas with high water pressure or a sudden increase in water pressure. Case). The sealing of the traditional EDR membrane stack is realized by physical pressing of the plastic edge sealing around the diaphragm and the diaphragm (the stainless steel end plates at both ends are reinforced with surrounding bolts). This kind of physical pressing has limited pressure bearing capacity, and has high requirements on the flatness of the diaphragm and the separator. In industrial applications, leakage often occurs due to loose fit. And once the i...
