example 1

[0022] Example 1: The membrane thread (010) adopts the 4.5X3.5mm special hollow fiber membrane produced by Guangdong Fenghe Clean Engineering Co., Ltd. The thickness of the lower flower plate is 3mm, and the hole diameter is 4.5mm. The number of holes is 300. Insert the ends of 300 membrane wires (010) into the holes of the lower flower plate (06) with special tooling. Place the lower flower board horizontally, and add glue to protect the ring. Use cyanoacrylic instant glue as the membrane filament penetrating glue (011), and use a glue dispenser to evenly inject the glue. Because the viscosity of the cyanoacrylic instant glue is very low (30-50cps), it is easy to penetrate the membrane wall, and a single layer of glue can already fix the membrane and the hole of the lower flower plate. The flower plate type reverse blowing membrane module produced in this way can work stably at normal temperature.

example 2

[0023] Example 2: The membrane thread (010) adopts the 5X4mm special hollow fiber membrane produced by Guangdong Fenghe Clean Engineering Co., Ltd. The thickness of the lower flower plate is 3mm, and the hole diameter is 5mm. The number of holes is 300. Use special tooling to insert the ends of 300 membrane threads (010) into the plate holes of the lower flower plate (06), place the lower flower plate horizontally, and add glue to protect the ring. Use 30--400cps low-viscosity modified epoxy resin as the membrane thread penetration glue (011), heat the lower flower plate (06) and membrane silk penetration glue (011) to 50 degrees to reduce the viscosity, and use a dispenser to evenly Inject glue and cure at 100 degrees Celsius. Then use heat-cured modified epoxy resin with a viscosity of about 3000cps as the adhesive layer (09) of the lower flower plate, inject the glue evenly with a glue dispenser, and cure at 100 degrees Celsius. The flower plate-type glue-sealed reverse ...

[0024] Example 3: The membrane thread (010) adopts the 5X4mm special hollow fiber membrane produced by Guangdong Fenghe Clean Engineering Co., Ltd. The thickness of the lower flower plate is 3mm, and the hole diameter is 5mm. The number of holes is 300. Use special tooling to insert the ends of 300 membrane threads (010) into the plate holes of the lower flower plate (06), place the lower flower plate horizontally, and add glue to protect the ring. Use 30--400cps low-viscosity modified epoxy resin as the membrane thread penetration glue (011), heat the lower flower plate (06) and membrane silk penetration glue (011) to 50 degrees to reduce the viscosity, and use a dispenser to evenly Inject glue and cure at 100 degrees Celsius. The difference from Example 2 is that no high-viscosity glue is used for the second layer pouring. The flower plate-type glue-sealed reverse blowing membrane module produced in this way can also work reliably at a temperature below 210 degrees, and c...

Abstract

The invention discloses a screen plate type glue-sealed blowback hollow fiber membrane assembly, and belongs to an improved miniature blowback pipe membrane assembly. The hollow fiber membrane filaments directly penetrate into the holes of a lower screen plate, and a layer of membrane filament permeation glue permeates into the micropores in the membrane filament walls, so that the membrane filaments have adhesiveness, are bonded and fixed with the plate hole walls of the lower screen plate, and then are reinforced by a layer of glue; and the micro blowback air pipe is fixed in the plate holeof the upper screen plate in a laser welding manner and is reinforced and fixed by a layer of glue. Not only fixing firmness is improved, but also conditions are created for automatic assembly of themembrane assembly, and mechanical large-scale production can be achieved.

Description

technical field [0001] The flower plate glue-sealed blowback hollow fiber membrane module is a hollow fiber membrane module with a flower plate to fix the membrane filament and a blowback device. Background technique [0002] The most common way to make hollow fiber membrane filaments into membrane modules is to bundle the membrane filaments, then pour and fix the ends with epoxy resin, and then cut them into alignment. The advantage of this is that the gap between the membrane filaments is small and the filling rate is high, which is suitable for occasions with less impurities, especially for liquid filtration. In recent years, hollow fiber membranes have been gradually applied to air filtration, especially for high dust filtration. The gap between the membrane filaments is small and the high filling rate has become a disadvantage. The hollow fiber membrane filaments must have appropriate distances and gaps to Accommodates accumulated dust, facilitates the removal of accum...
