Description

Split type diaphragm capsule of curtain formula membrane

Technical Field

The utility model belongs to the technical field of hollow fiber curtain-type membrane, concretely relates to split type diaphragm capsule of curtain-type membrane.

Background

The traditional hollow fiber curtain type membrane is usually manufactured by adopting an integrated membrane box, the membrane box comprises a water collecting pipe and a pouring area connected to the top of the water collecting pipe, and due to the structural limitation of the membrane box, the top of the pouring area above the membrane box is subjected to glue pouring in a common glue pouring mode at present, and membrane wires and the membrane box are poured together. According to the pouring method, all membrane wires are required to be plugged in advance, then primary glue sealing is carried out, after a glue sample is solidified, the membrane wire holes are cut to achieve the water production function, the cut glue sealing strips are matched with the membrane box, and then a curtain type membrane is manufactured through secondary glue injection. The manufacturing process has higher requirement on the hole plugging process, and when the sizes of the sealing rubber strip and the diaphragm capsule are not well matched, the pouring sealant easily flows out from the joint, so that the water collecting flow channel is blocked, and the curtain type diaphragm can not normally produce water.

In order to solve the above problems, there are some patents which improve the structure of the bellows or the casting process. For example, in chinese patent publication No. CN109772171A, a pouring nozzle is provided at the bottom of a pouring basin of a conventional curtain type membrane cassette, the pouring nozzle is connected to a pouring box through a pouring pipe, and resin pouring material flows into the pouring basin from the pouring nozzle at the bottom of the pouring basin by its own weight. In the chinese patent publication No. CN108786472A, a plugging solution is used to plug the holes in advance in the membrane threads, and then glue injection is performed, which has a high requirement for the operation technique, because of the nature of the capping solution, the liquid level is easy to sink and the holes are still plugged during glue injection, and if the capping solution is too high, the curing of the potting adhesive is affected, and the perforation phenomenon of the adhesive is caused. In chinese patent publication No. CN104582817A, a membrane bundle is formed by using an adhesive layer, the ends of membrane filaments are covered by using a permeation vessel, and a liquid potting compound flows into the vessel to fill the space between the membranes and cover the adhesive layer, in this method, the potting compound does not block the membrane pores, cutting is not required, the area of the membrane filaments is prevented from being wasted by cutting, operation steps are omitted, operation time is saved, but an additional permeation vessel device is required, the sealing process is closed, the sealing state cannot be directly observed, if the sealing is not in place, the potting compound pollutes the membrane filaments or blocks part of the membrane pores, an additional protective cover device is required to be added, the sealing process after sealing is closed, only single-point potting is performed, it cannot be guaranteed that the potting compound sufficiently enters the middle of the membrane filaments, and the potting through-hole phenomenon is easy to occur.
