Description

Technical Field

[0001] The present invention relates to the technical field of film production equipment, and in particular to an all-in-one automatic production machine for water treatment functional membranes. Background Art

[0002] Water treatment membrane is a special filter membrane, whose function is to separate solid particles, dissolved matter, and suspended matter in water through physical or chemical methods, so that the water can be purified and reused. The existing functional membrane material is a new type of high-efficiency separation material. According to its structure and functional characteristics, it can be divided into many types, including but not limited to reverse osmosis membrane, nanofiltration membrane, ultrafiltration membrane, microfiltration membrane and special functional membrane. Functional membrane materials are widely used in the field of water treatment. They can not only effectively remove pollutants in water and improve water quality, but also play an important role in atmospheric pollution control, solid waste treatment and ecological restoration, so as to improve the functionality of water treatment membranes in purifying water quality and recycling resources.

[0003] Interfacial polymerization is a method for preparing membranes by polycondensation at the interface of two immiscible solutions containing two different monomers. Specifically, two highly reactive monomers are placed in separate immiscible solvents, such as an aqueous phase and an organic phase. When these two phases come into contact, polymerization occurs at the interface. The polymer obtained during the polymerization reaction is insoluble in the solvent and precipitates at the interface, thereby forming a very thin dense layer on the porous support as a membrane structure. During the preparation, the support is first immersed in an aqueous solution containing an active monomer to fully soak it. After the excess solution is discharged, it is immersed in an organic phase containing another active monomer. The two monomers react with each other on the surface of the support to form a dense polymer cortex, and finally form a composite membrane, which improves the permeability and selectivity of the treatment membrane. If manual coating is used for coating of existing interfacial polymerization membranes, it cannot ensure uniform coating, and the efficiency of manual coating is low and cannot be applied to continuous production. Although coating equipment can improve work efficiency, since the existing coating equipment mainly adopts slit and scraping methods for coating, the coating head using slit and scraping cannot ensure coating saturation, and since the organic phase coating liquid has a certain viscosity, the above-mentioned coating head is difficult to control the liquid output, which easily causes uneven coating and is not suitable for the production of water treatment functional membranes.

[0004] Reference patent announcement number is "CN214764580U", and the name is "A coating device for preparing composite membranes by interfacial polymerization". The Chinese utility model patent discloses "A coating device for preparing composite membranes by interfacial polymerization, comprising a base film unwinding shaft, a polyamine aqueous solution dipping tank, a front air knife, a back squeezing roller, a closed space, a solvent collection tank and a drying channel arranged in sequence from the starting end of the preparation device. Support guide rollers are provided between each device to support the composite membrane. The polysulfone porous supported base membrane is passed through the polyamine aqueous solution dipping tank at a certain speed by the base film unwinding shaft, and the excess amine liquid on the surface of the base membrane is removed by squeezing with a front air knife and a back squeezing roller, and then detoured to a closed space with the front side of the membrane facing up for polymerization reaction. After the composite membrane comes out of the closed space, it detoured to the oven above. At this time, the organic solution collection tank arranged below is again It is used to collect excess solution so that there is very little excess solution and content left on the membrane surface, and then enter the drying channel. After entering the drying channel, it finally enters the cleaning, coating and dry film preparation process stage until the winding is completed. "Although this technical solution can use interfacial polymerization reaction to produce polyamide composite reverse osmosis membranes, the equipment will destroy the coating reaction surface during the washing process, and the coating curing time is insufficient. In addition, the equipment mainly uses slit coating for coating. However, when slit coating is used to apply viscous oil-phase coating liquid, it still cannot ensure the saturation of the surface coating liquid, which in turn causes the water-phase coating liquid and the oil-phase coating liquid to fail to fully react, affecting production quality. Therefore, since this equipment is prone to insufficient reaction, it is not suitable for the production of water treatment composite membranes. Therefore, it is also not suitable for the continuous and automated production of water treatment functional membranes.

[0042] Specifically, bearing seats are provided at both ends of the plurality of guide rollers 44 , and the bearing seats of two of the guide rollers 44 are respectively provided at both ends of the reaction chamber body 4 through elastic connection.

[0043] In the first embodiment, in order to realize automation, the interfacial polymerization film-making method is adopted to produce the water treatment functional membrane, and before the interfacial polymerization reaction, it is ensured that the coating liquid of the base film is saturated to ensure sufficient reaction. Since the existing coating method cannot ensure the saturation of the coating liquid and the reaction time is insufficient, the interfacial polymerization reaction is insufficient, which affects the production quality. In this embodiment: a film supply roller 1 for supplying the base film, a dipping tank 2, a coating device 3, a reaction chamber 4, and a film collection roller 5 are provided; the film supply roller 1 is arranged outside the dipping tank 2, and the dipping tank 2 is provided. The discharge port is close to the coating device 3, so that the base film enters the dipping water tank 2 for full dipping in the aqueous solution. The base film dipped in the aqueous solution can be at the bottom of the coating device 3 through the discharge port, and the coating device 3 performs overflow coating on it. A reaction plane 40 for conveying the coating base film is provided just above the reaction bin 4, and a film feed port and a film discharge port are provided at both ends of the reaction bin 4, so that the two ends of the reaction plane 40 are aligned with the film feed port and the film discharge port, respectively. An air drying device 7 is provided at the other end of the reaction bin 4, so that the coating device 3 is provided near the film feed port. At the top of the opening, when the base film with the aqueous solution passes through the coating device 3 at the film inlet opening, the coating device 3 is sprayed with liquid. The coating device 3 includes an overflow arc plate 31. An inlet arc groove 311 and an outlet arc groove 312 are provided inside the overflow arc plate 31. Openings for the coating liquid to enter are provided at both ends of the inlet arc groove 311, so that the outlet arc groove 312 is adjacent to the inlet arc groove 311. Since the horizontal height of the outlet arc groove 312 is less than the horizontal height of the inlet arc groove 311, the coating liquid overflows in an overflow manner. Due to the overflow The arc plate 31 is horizontally arranged on the top of the reaction plane 40, and the coating liquid overflows to the surface of the base membrane with the aqueous solution through the liquid outlet arc groove 312, so that the surface of the base membrane with the aqueous solution is saturated with the coating liquid, and moves close to the air-drying device 7 through the reaction plane 40, and the interfacial polymerization reaction is fully carried out during the transportation process. Finally, the coating on the surface of the base membrane after sufficient reaction is air-dried and cured by the air-drying device 7, and is rolled up by the film-receiving roller 5 to complete the action of automatically producing the water treatment functional membrane. It is suitable for continuous production, improves production efficiency and ensures production quality.

[0044] It should be noted that a liquid supply device may be provided on the outside of the coating device 3, and the coating liquid is input through the liquid supply device through a pipeline to the opening of the liquid inlet arc groove 311. When the coating liquid in the liquid inlet arc groove 311 exceeds the plane height of the liquid inlet arc groove 311, the coating liquid will overflow into the interior of the liquid outlet arc groove 312 until the coating liquid exceeds the plane height of the liquid outlet arc groove 312 and then overflows and is coated on the base film with aqueous solution on the reaction plane 40.

[0045] It is particularly noted that in this embodiment, the surface of the base film is over-coated by overflow coating to ensure that the coating is saturated so that the organic phase coating can fully contact the aqueous phase to achieve a full reaction effect, and the reaction time can be ensured when moving on the reaction plane 40 to allow it to fully undergo interfacial polymerization reaction.

[0046] It should also be noted that by providing connecting vertical plates 43 on both sides of the outside of the reaction chamber body 4, adjustment mechanisms 8 connected to the overflow arc plate 31 are provided on the opposite sides of the two connecting vertical plates 43. The adjustment mechanism 8 can be used to control the lifting height of the overflow arc plate 31. The lifting height of the overflow arc plate 31 is controlled by the adjustment mechanism 8 to adjust the distance between the overflow arc plate 31 and the reaction chamber body 4, thereby adjusting the distance between the overflow arc plate 31 and the base film on the reaction plane 40. The amount of coating overflowing from the overflow arc plate 31 flows steadily, and the closer the overflow arc plate 31 is to the reaction plane 40, the more coating is applied, and the farther the overflow arc plate 31 is from the reaction plane 40, the less coating is applied. The use of this adjustment mechanism 8 can be applied to base films of different thicknesses for overflow saturation coating.

[0047] In response to the above description, it should be added that the above-mentioned adjustment mechanism 8 includes a lifting component 81 and a sliding plate 82. The power output end of the lifting component 81 is connected to the top of the connecting vertical plate 43, so that the sliding plate 82 is movably arranged on the connecting vertical plate 43, and the sliding plate 82 is also fixedly connected to the end of the overflow arc plate 31. Therefore, the lifting component 81 can be used to control the lifting height of the sliding plate 82. The lifting component 81 can adopt a screw lift structure as the main structure. The screw lift can accurately control and adjust the lifting or propulsion height according to a certain procedure. It can be directly driven by an electric motor or other power, or it can be adjusted manually.

[0048] In the second embodiment, in order to realize the automation of making the base film enter the inside of the dipping tank 2 in a straight manner, the base film is dipped into the aqueous solution through the dipping tank 2 to ensure that the base film is fully infiltrated so that the subsequent aqueous solution and the saturated coating liquid can fully react. In this embodiment: a film supply roller 1 and a dipping tank 2 for supplying the base film are provided, the film supply roller 1 is arranged outside the dipping tank 2, and a traction device 9 is provided at the film outlet end of the film supply roller 1. The traction device 9 includes a tensioning guide roller 91 and a lifting guide roller 92. The lifting guide roller 92 is movably arranged directly below the tensioning guide roller 91. A lifting cylinder 93 is connected to both ends of the lifting guide roller 92 to make the lifting cylinder 93 The power output end is connected to the two ends of the lifting guide roller 92, and the lifting height of the lifting guide roller 92 can be controlled by the lifting cylinder 93. When the base film needs to be tensioned at the film outlet end of the film supply roller 1, the lifting guide roller 92 can be driven to descend by the lifting cylinder 93, so that the distance between the lifting guide roller 92 and the tensioning guide roller 91 becomes larger, and before the base film enters the dipping tank 2 through the lifting guide roller 92 and the tensioning guide roller 91, the traction straightening effect is achieved, ensuring that the base film can remain straight and enter the dipping tank 2. The base film is soaked in the aqueous solution inside the dipping tank 2, so that the surface of the base film can be fully infiltrated, so as to facilitate the subsequent sufficient interfacial polymerization reaction with the coating liquid.

[0049] In this embodiment, it is necessary to remove excess water from the surface of the base film with water. When the base film enters the dipping tank 2 for immersion, in order to prevent excessive moisture on the surface of the base film, it is necessary to remove excess moisture from the surface of the base film before the wet base film enters the coating device 3. It is further described that a plurality of film guide rollers 21 are arranged inside the dipping tank 2, and the plurality of film guide rollers 21 are evenly arranged inside the dipping tank 2. A scraping inclined plate 22 is also arranged inside the dipping tank 2, so that the inclined surface of the scraping inclined plate 22 faces the outside of one of the film guide rollers 21. The base film is introduced into the traction device 9 through the plurality of film guide rollers 21, so that the base film maintains tension inside the dipping tank 2, ensuring that the base film can fully contact the aqueous solution inside the dipping tank 2, so that its surface is fully soaked, and the scraping inclined plate 22 is used to remove excess water from the surface of the base film before the film is discharged to the coating device 3, so as to prevent the soaked base film from dripping water when moving close to the coating device 3, and ensure that the water on the surface of the base film is uniform.

[0050] In the third embodiment, in order to automatically scrape off the excess coating of the reaction coating to ensure a uniform coating effect, the coating liquid is applied to the surface of the base film with the aqueous solution by spray coating, which can ensure that the organic phase coating liquid and the aqueous phase solution are fully polymerized on the surface of the base film. However, after the reaction, the excess surface coating liquid needs to be removed to ensure a uniform coating. In this embodiment: a film supply roller 1 for supplying the base film, a dipping tank 2, a spray coating device 3, a reaction chamber 4, and a film collection roller 5 are provided; the film supply roller 1 is provided near the outside of the dipping tank 2, and the discharge port of the dipping tank 2 is close to the spray coating device 3, so that the base film enters the dipping tank 2 for being fully dipped in the aqueous solution. The base film dipped in the aqueous solution can be at the bottom of the spray coating device 3 through the discharge port, and is subjected to overflow coating by the spray coating device 3. A reaction plane 40 for conveying the coating base film is provided just above the reaction chamber 4, and both ends of the reaction chamber 4 are divided into A film inlet and a film outlet are separately provided so that the two ends of the reaction plane 40 are aligned with the film inlet and the film outlet respectively. An air drying device 7 is provided at the other end of the reaction chamber body 4, so that the coating device 3 is provided at the top near the film inlet. During the reaction process, a liquid uniformity device 6 is provided on the top of the reaction plane 40 so that the liquid uniformity device 6 is adjacent to the coating device 3. The liquid uniformity device 6 includes a liquid uniformity roller 61 and a support plate group, so that the outside of the support plate group is movably provided with a lifting slide 63. A liquid uniformity roller 61 and a driving mechanism 64 are provided on the outside of the lifting slide 63, and the liquid uniformity roller 61 is rotated and arranged on the lifting slide 63. The power output end of the driving mechanism 64 is also connected to one end of the liquid uniformity roller 61 by transmission, so that the driving mechanism 64 drives the liquid uniformity roller 61 to rotate, and the excess saturated coating liquid after sufficient reaction on the reaction plane 40 is scraped off by the liquid uniformity roller 61 to prevent excessive coating and ensure uniform coating.

[0051] It should be noted that, by arranging a plurality of guide rollers 44 on the top of the reaction chamber body 4, the plurality of guide rollers 44 are spaced apart along the film discharge direction of the reaction chamber body 4, so that the tops of the plurality of guide rollers 44 are tangent to the bottom of the reaction plane 40, and then the plurality of guide rollers 44 can support the film body, ensuring that the bottom of the film body is kept straight for transportation.

[0052] It should also be noted that when scraping off excess coating, the excess coating liquid will fall into the interior of the reaction chamber 4 and needs to be recovered. In this embodiment, the bottom of the reaction chamber 4 can be tilted downward to facilitate the collection of excess liquid. Since a drainage hole for recovering the coating liquid is provided at the bottom of the reaction chamber 4, the excess liquid can be discharged through the drainage hole for centralized recovery and treatment.

[0053] It is particularly noted that the support plate group includes two relatively arranged support plates 621, and the two support plates 621 are respectively arranged on both sides of the outside of the reaction chamber body 4. By rotating an adjusting screw 622 provided on the support plate 621, the end of the adjusting screw 622 is connected to the top of the lifting slide 63. The adjusting screw 622 can be rotated to adjust the lifting height of the lifting slide 63, and then the distance between the liquid uniformizing roller 61 and the reaction plane 40 can be controlled. By adjusting the height of the liquid uniformizing roller 61, the thickness of the base film interface polymerization reaction layer can be controlled, and the thickness of the surface coating can be controlled according to actual production needs.

[0054] Embodiment 4, in order to realize automatic rapid air drying of the surface polymerization reaction layer of the base film after the interfacial polymerization reaction, since the interfacial polymerization reaction layer is still in an unsolidified state after the reaction on the surface of the base film, the interfacial polymerization reaction layer needs to be rapidly air dried to facilitate the subsequent winding action. In this embodiment: an air drying device 7 is provided at the other end of the reaction chamber body 4, and the coating device 3 is provided at the top near the film inlet. When the base film with the aqueous solution passes through the coating device 3 at the film inlet opening, the coating device 3 is sprayed with liquid to make the surface of the base film with the aqueous solution saturated with the coating liquid, and moves close to the air drying device 7 through the reaction plane 40, so as to realize full interfacial polymerization during the transportation process. After the surface polymerization reaction, the coating on the surface of the base film that has fully reacted is finally air-dried and cured by the air-drying device 7. The air-drying device 7 includes a solid-liquid air knife 71 and a scraper convex plate 72. The solid-liquid air knife 71 is set on the top of the scraper convex plate 72, and the scraper convex plate 72 is located directly below the reaction plane 40. The outer protrusion of the scraper convex plate 72 is aligned with the air outlet of the solid-liquid air knife 71. When the base film coated with paint on the reaction plane 40 passes through the scraper convex plate 72, the scraper convex plate 72 can scrape off the excess paint at the bottom of the base film to ensure the cleanliness of the bottom of the base film, and the solid-liquid air knife 71 is used to quickly air-dry and cure the paint on the surface of the base film after the reaction, so as to facilitate subsequent winding.

[0055] In response to the above description, it should be added that by arranging a plurality of guide rollers 44 on the top of the reaction chamber body 4, the plurality of guide rollers 44 are arranged at intervals along the film outlet direction of the reaction chamber body 4, and the tops of the plurality of guide rollers 44 are all tangent to the bottom of the reaction plane 40, so that the plurality of guide rollers 44 can support the bottom of the film body on the reaction plane 40, and can ensure that the film body remains straight for sufficient reaction.

[0056] In response to the above description, further limitations are made. Bearing seats are provided at both ends of several guide rollers 44, and the bearing seats of two of the guide rollers 44 are elastically connected and respectively arranged at the two ends of the reaction chamber body 4. The two guide rollers 44 close to the two ends of the reaction chamber body 4 can have a buffering effect through the elastic connection, so that the base film with the aqueous solution will not drop too much due to excessive force at the corners before entering the reaction plane 40, and it is also ensured that when the coating film after the interface contact reaction comes out of the film through the reaction plane 40, its surface coating will not crack due to the large force at the corners, thereby ensuring production quality.
