Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane production, in particular to a reverse osmosis membrane production base membrane suspension drying machine. Background Art

[0002] The reverse osmosis membrane is the core component for achieving reverse osmosis, which can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. After the reverse osmosis membrane is coated, it needs to be dried to achieve the finished product production of the reverse osmosis membrane.

[0003] Among them, the publication number CN112179105A is a base film hanging drying device for reverse osmosis membrane production, which includes a conveying mechanism, a drying mechanism for conveying base film and a follower mechanism for conducting hot air. The conveying mechanism includes a support base, a conveying roller support, a motor, a conveying roller 1, and a lifting bracket. The top of the support base is fixedly connected to the conveying roller support. The front part of the conveying roller support is provided with the motor for driving the conveying roller 1 arranged between the two conveying roller supports to rotate. The top of the conveying roller supports arranged in parallel on both sides is provided with the lifting bracket. The invention adopts a conveying mechanism and a follower mechanism, so that the distance between the conveying roller 1 and the conveying roller 2 can be adjusted, thereby adapting to base films of different thicknesses. It is easy to use, and adopts a drying mechanism, so that hot air can be sprayed to the upper and lower surfaces of the base film, so that the drying efficiency is high.

[0004] The above-mentioned prior art utilizes air guide plates to achieve double-sided drying of the reverse osmosis membrane, but this drying method directly sprays air onto the reverse osmosis membrane. The large air impact force can easily cause damage to the reverse osmosis membrane, and the reverse osmosis membrane cannot be vibrated with the help of airflow during drying, which is not conducive to promoting the separation of water molecules in the reverse osmosis membrane and accelerating the drying of the reverse osmosis membrane. Therefore, we proposed a reverse osmosis membrane production base membrane suspension drying machine to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5The utility model provides the following technical scheme: a suspended drying machine for reverse osmosis membrane production base film, comprising a workbench 1, a winding drum 2 is installed at the front end of the workbench 1, and a discharging drum 3 is installed at the rear end of the workbench 1; a bracket plate 4 is installed on the upper side of the middle section of the workbench 1, and the upper end of the bracket plate 4 is connected to a supporting frame 5, and the upper and lower side surfaces of the supporting frame 5 are elastically connected to an air collecting box 12 through a spring 10, and a moving rod 11 is connected to the outer side of the air collecting box 12, and a second magnet 14 is installed at the end of the moving rod 11, and a nozzle 13 is connected to the side of the air collecting box 12 away from the moving rod 11, and a secondary hose 15 is connected between the air collecting boxes 12; a hot air blower 16 is installed on the side of the supporting frame 5, and the air outlet of the hot air blower 16 is connected to a main hose 17, and one end of the main hose 17 is connected to the air collecting box 12; the nozzle 13 is a bent structure, and the nozzles 13 are evenly spaced and distributed on the air collecting box 12, and the nozzles 13 are used to buffer the airflow;

[0026] The reverse osmosis membrane base film is distributed between the winding drum 2 and the unwinding drum 3, and the winding drum 2 and the unwinding drum 3 rotate synchronously to transport the reverse osmosis membrane base film. The coated reverse osmosis membrane base film passes through the support frame 5, and the hot air blower 16 is powered on to transport the hot air to the air collecting box 12 through the main hose 17. The air collecting boxes 12 are connected by the auxiliary hose 15 to transport the hot air. The hot air is ejected through the nozzle 13 to dry the reverse osmosis membrane base film, and the nozzle 13 is bent, so it can buffer the ejected hot air to prevent the air impact from damaging the reverse osmosis membrane base film;

[0027] A pulley 6 is rotatably connected to the corner of the support frame 5, and the rear end of the pulley 6 is connected to the output end of the motor 7. The motor 7 is installed on the rear side of the support frame 5. The outer side of the pulley 6 is fitted and connected to the steel plate conveyor belt 18, and a mounting seat 8 is installed on the inner side of the steel plate conveyor belt 18. The inner side of the mounting seat 8 is connected to the first magnet 9; the support frame 5 is a "U"-shaped structure, and the support frame 5 is located on the inner side of the steel plate conveyor belt 18. The steel plate conveyor belt 18 is a "U"-shaped structure, which can make the steel plate conveyor belt 18 rotate smoothly on the periphery of the support frame 5 to avoid mutual obstruction between the two; the outer diameter of the middle part of the pulley 6 is smaller than the outer diameter of the end part of the pulley 6, and the inner side of the pulley 6 is smaller than the outer diameter of the end part of the pulley 6. The vertical plane where the minimum outer diameter section is located coincides with the vertical plane where the mounting seat 8 is located, so that when the steel plate conveyor belt 18 moves to control the mounting seat 8 to move, the mounting seat 8 can smoothly pass through the minimum outer diameter section of the pulley 6 to avoid it blocking the mounting seat 8; the first magnet 9 and the second magnet 14 are arranged corresponding to each other, and the first magnet 9 and the second magnet 14 are magnets of the same polarity. The repulsive force between the magnets is used to drive the moving rod 11 to drive the air collecting box 12 to move, and adjust the distance between the nozzle 13 and the reverse osmosis membrane base membrane; the moving rod 11 passes through the side wall of the supporting frame 5, and the moving rod 11 is slidably connected to the supporting frame 5, which can ensure the smooth movement of the moving rod 11 and smoothly drive the air collecting box 12 to move;

[0028] The motor 7 is connected to the power supply to control the pulley 6 to rotate, thereby controlling the movement of the steel plate conveyor belt 18 connected on the outside, and the steel plate conveyor belt 18 controls the movement of the mounting seat 8 installed on the inside. When the position of the first magnet 9 connected in the mounting seat 8 corresponds to the position of the second magnet 14, the magnets with the same polarity distribution repel each other, and the moving rod 11 drives the air collecting box 12 to move in the direction close to the reverse osmosis membrane base membrane. At the same time, the air collecting box 12 stretches and accumulates the spring 10, and controls the nozzle 13 to gradually approach the reverse osmosis membrane base membrane. The force on the reverse osmosis membrane base membrane increases, and the reverse osmosis membrane base membrane is dried at the same time. When the positions of the first magnet 9 and the second magnet 14 are offset, the repulsive force is released, and the spring 10 can control the air collecting box 12 to reset and move, so that the nozzle 13 is gradually reset away from the reverse osmosis membrane base membrane, and the force on the reverse osmosis membrane base membrane is reduced. According to the above steps, different positions of the reverse osmosis membrane base membrane can be intermittently pushed to make the reverse osmosis membrane base membrane produce tiny vibrations, thereby promoting the separation and drying of water molecules in the reverse osmosis membrane base membrane and accelerating the drying of the reverse osmosis membrane base membrane.
