Combination unit and combination method of multiple membrane shells

摘要

The present invention discloses a combination unit and method of multiple membrane shells. The combination unit of multiple membrane shells is formed by bundling multiple membrane shells in parallel, wherein the raw water port and the concentrated water port of each of the membrane shells are respectively connected and sealed with the raw water port and the concentrated water port of the adjacent membrane shells to form the shared raw water port and the shared concentrated water port which are respectively connected with the raw water pipeline and the concentrated water pipeline. Since each of the combination units of multiple membrane shells is provided with the shared raw water port and the shared concentrated water port, it is adequate to finish the assembly of the shared raw water port with the pipeline and the assembly of the shared concentrated water port with the pipeline in the engineering installation. The combination unit of multiple membrane shells can be placed horizontally or vertically. By adopting the technology of the combination unit of multiple membrane shells, there does not need a large number of clamps, the number of sealed points is decreased, the engineering cost is reduced, the hidden seepage danger is lowered, the engineering installation workload is lessened, the occupied area of the apparatus is saved, and the maintenance and the service are convenient.

主权项

1. A combination unit of multiple membrane shells, formed by bundling a plurality of membrane shells in parallel, wherein a raw water port and a concentrated water port of each of the membrane shells are respectively interconnected with those of an adjacent membrane shell, the combination unit of multiple membrane shells being formed with at least one shared raw water port and at least one shared concentrated water port which are respectively capable of being connected with a raw water pipeline and a concentrated water pipeline, correspondingly connected two raw water ports or two concentrated water ports of two adjacent membrane shells are interconnected by one adapter without using a clamp, each adapter forming a connection between two raw water ports or two concentrated water ports and wherein there is provided a seal extending around each adapter and wherein the seal is compressed by two adjacent membrane shells so as to seal the connection formed by the adapter, the combination unit of multiple membrane shells further comprising a binding firmware which is arranged at a periphery of the plurality of membrane shells bundled in parallel for combining the plurality of membrane shells into an integrated unit; wherein the binding firmware comprises a rigid or flexible binding tape that extends around the membrane shells and a pressure adjuster operatively connected between one of the membrane shells and the binding tape for preloading the binding tape and automatically adjusting the tension of the binding tape by using the pressure inside the membrane shells; and wherein each pressure adjuster comprises a preloaded bolt, a preloaded cushion block and a piston, and wherein the preloaded bolt is operative to position the preloaded cushion block and adjust a gap between a respective binding tape and the membrane shell in order to preload the binding tape.
