Description
Technical Field
A flower plate type glue-sealed back-blowing hollow fiber membrane component is a hollow fiber membrane component which uses flower plates to fix membrane wires and is provided with a back-blowing device.
Background
The most common way of making membrane modules from hollow fiber membrane filaments is to bundle the membrane filaments, then pour and fix the ends with epoxy resin, and then cut them together. The advantages of this are small gaps between membrane filaments, high packing rate, and suitability for the occasions with less impurity filtration, especially for the occasions with liquid filtration. In recent years, hollow fiber membranes are gradually applied to air filtration, particularly high-dust filtration, but the defects of small gaps among membrane filaments and high filling rate are overcome, and proper distances and gaps are required among the hollow fiber membrane filaments to accommodate accumulated dust, so that the accumulated dust is convenient to fall off, and the back flushing function is also provided.
To solve this problem many new solutions have emerged, typically CN200905454U, CN207287148U, CN 109692535A. Common features of these schemes are: the hollow fiber membrane filaments are penetrated into holes on a flower plate (also called a screen plate) one by one, the spacing distance between the membrane filaments is fixed by the spacing distance between the holes on the flower plate, one surface of the flower plate is used as the end surface of the membrane component, a new membrane component form is formed, the membrane component is named as a flower plate type hollow fiber membrane component, and the classification of the flower plate type back-blowing hollow fiber membrane component is generated due to the back-blowing function combined on the membrane component. The invention belongs to the type, and has the innovation points that a plurality of miniature back blowing nozzles are reinforced and fixed by using glue layers; the membrane silk penetrating glue is used for solving the adhesion between the membrane silk and the hole wall of the pattern plate; and reinforcing the fixation of the membrane filament group and the chemical plate by using an adhesive layer. Therefore, the membrane is named as a flower plate type glue sealing back-blowing membrane component.
Due to the new structural form, a plurality of specific technical problems need to be further solved so as to achieve the goals of practicability and advancement.
CN207287148U adopts the gluing method of injecting glue at two layers of screen plates, and this kind of mode, the advantage can pinpoint the relative position between the membrane silk, and the bonding is also very reliable, and the shortcoming is, need to pass the membrane silk twice screen plate hole, is difficult when mass production. Meanwhile, the sieve plate is not directly used as the working surface or the outer vertical surface of the membrane component in the mode.
CN200905454U and CN109692535A are novel membrane modules in the form of micro blowback tubes, wherein, a structure that membrane filaments are sleeved on a tuyere and then the tuyere is fixed on a pattern plate is adopted. The inventor utilizes the structure to carry out a plurality of field applications for more than two years, and particularly, the application is successful in a lead smoke treatment device with an industrial scale of 7 ten thousand cubic meters. However, repeated practice shows that the membrane wires with the structure are easy to fall off, the manual installation is complicated, and automation is difficult to realize. Especially, when the large-scale production is carried out, the number of the membrane wires is tens of thousands, hundreds of thousands, huge labor hour is consumed for the air nozzles with huge number and the membrane wires with the same number to be butted by hand, and the automation is extremely difficult, so that the feasibility of the structure is lost.
Disclosure of Invention
The invention aims to: air nozzles in CN200905454U and CN109692535A are omitted, and the defect that membrane wires are connected by the air nozzles is overcome; the defect that membrane wires need to pass through two or more sieve plates is avoided; the problems of corrosion resistance and high temperature resistance of the pattern plate type back-blowing membrane component are solved; the problem of reliability of combination of the membrane wires and the plate holes is solved; provides a novel flower plate type back-blowing membrane component structure with simple process and reliable connection, and creates conditions for automatically assembling membrane components.
The main improvement measures of the invention to the prior art are as follows:
1. the connecting mode of the blowback nozzle and the upper pattern plate is improved to be a mode of laser welding. In order to further improve the reliability, a layer of fixing adhesive layer is added on the surface of the upper pattern plate.
2. The original 'tuyere' that is used for connecting lower card and membrane silk is saved, directly fixes the membrane silk in the plate hole of card under. The lower pattern plate is very thin and is only 1-5 mm, so that the membrane yarn is particularly favorable for passing through, and conditions are created for realizing batch penetration by utilizing a tool.
3. The viscose glue used for fixing the lower pattern plate and the membrane silk is two layers. Firstly, micropores densely distributed on the membrane silk wall are utilized, low-viscosity glue with good permeability is used for permeating the micropores on the membrane silk wall, the affinity between the membrane silk and the glue is solved, the membrane silk has wettability, meanwhile, the low-viscosity glue permeates the gap between the membrane silk wall and the hole of the lower pattern plate, and the membrane silk and the hole of the lower pattern plate are fixed together after solidification. This is important because the polytetrafluoroethylene materials commonly used are difficult to bond effectively to the adhesive due to the inherent non-stick properties of the materials. And then, in order to further improve the reliability, a fixing glue layer is added on the cured low-viscosity glue. In order to save assembly time and realize mass and continuous production, the two adhesives are quick-drying adhesives, such as UV curing adhesives or thermosetting adhesives.
4. Except for the membrane wires and the glue, the surface of each component of the membrane component is coated and electroplated, so that the corrosion resistance is enhanced.

Detailed description of the invention
According to the principle provided by the invention, the membrane silk is directly penetrated in the plate hole of the lower pattern plate, so that the manual operation of installing the membrane silk on the air nozzle and fixing the air nozzle on the lower pattern plate is much simpler than the prior art. Meanwhile, the automatic operation is possible by using a mechanical method. Regarding the tool for batch membrane threading, additional patent will be applied.
Example 1: the membrane wire (010) adopts a hollow fiber membrane which is produced by Guangdong wind and clean engineering limited company and is specially used for 4.5X3.5mm air cleaning. The thickness of the lower pattern plate is 3mm, and the aperture is 4.5 mm. The number of the holes is 300. The ends of 300 membranous fibers (010) penetrate into plate holes of the lower pattern plate (06) by a special tool. The lower pattern plate is horizontally placed, and the glue is added to enclose and block the guard ring. Cyanoacrylate instant glue is adopted as the membrane thread permeation glue (011), and a glue dispenser is used for uniformly injecting glue. Because the viscosity of the cyanoacrylate instant glue is very low (30-50 cps), the cyanoacrylate instant glue can easily penetrate through the wall of the membrane silk, and the single-layer glue can already fix the membrane silk and the lower pattern plate hole. The produced card type back-blowing membrane component can stably work at normal temperature.
Example 2: the membrane wire (010) adopts a hollow fiber membrane special for 5X4mm air purification produced by Guangdong wind and clean engineering limited company. The thickness of the lower pattern plate is 3mm, and the aperture is 5 mm. The number of the holes is 300. The end parts of 300 membrane filaments (010) penetrate into plate holes of a lower pattern plate (06) by using a special tool, the lower pattern plate is horizontally placed, and glue is added to enclose and block the guard ring. The low-viscosity modified epoxy resin with the viscosity of 30-400 cps is used as the membrane thread permeable adhesive (011), the lower pattern plate (06) and the membrane thread permeable adhesive (011) are heated to 50 ℃ to reduce the viscosity, the glue is uniformly injected by a glue dispenser, and the curing is carried out at 100 ℃. And then thermosetting modified epoxy resin with the viscosity of about 3000cps is adopted as a lower pattern plate adhesive layer (09), glue is evenly injected by a glue dispenser, and the curing is carried out at 100 ℃. The produced card-type glue-sealing back-blowing membrane component can reliably work at the temperature below 210 ℃.
Example 3: the membrane wire (010) adopts a hollow fiber membrane special for 5X4mm air purification produced by Guangdong wind and clean engineering limited company. The thickness of the lower pattern plate is 3mm, and the aperture is 5 mm. The number of the holes is 300. The end parts of 300 membrane filaments (010) penetrate into plate holes of a lower pattern plate (06) by using a special tool, the lower pattern plate is horizontally placed, and glue is added to enclose and block the guard ring. The low-viscosity modified epoxy resin with the viscosity of 30-400 cps is used as the membrane thread permeable adhesive (011), the lower pattern plate (06) and the membrane thread permeable adhesive (011) are heated to 50 ℃ to reduce the viscosity, the glue is uniformly injected by a glue dispenser, and the curing is carried out at 100 ℃. The differences from example 2 are: no longer use high viscosity glue to perform layer 2 casting. The produced card-type glue-sealing back-blowing membrane component can also reliably work at the temperature below 210 ℃, has certain strength and durability, and has simpler process.
Example 4: the membrane wire (010) adopts a hollow fiber membrane special for 5X4mm air purification produced by Guangdong wind and clean engineering limited company. The thickness of the lower pattern plate is 3mm, and the aperture is 5 mm. The number of the holes is 300.

And then adopting UV curing structural adhesive with the viscosity of about 3000cps as a lower pattern plate adhesive layer (09), uniformly injecting glue by using a glue dispenser, and curing by ultraviolet rays. The produced card-type glue-sealing back-blowing membrane component can reliably work at the temperature below 150 ℃.
