Description

Technical Field

[0001] The utility model relates to the technical field of nanofiltration membrane element production, in particular to a glue coating device for nanofiltration membrane element production based on alignment technology. Background Art

[0002] Nanofiltration technology has been separated from reverse osmosis technology and has become an independent separation technology between ultrafiltration and reverse osmosis technologies. It has been widely used in many fields such as seawater desalination, ultrapure water production, food industry, environmental protection, etc., and has become an important branch of membrane separation technology;

[0003] At present, the application fields of nanofiltration membranes in China mainly focus on industrial separation, sewage and wastewater treatment, reclaimed water treatment and seawater desalination. As an advanced and competitive industrial separation and water treatment technology at present, nanofiltration membrane technology is very compatible with the concept of building an energy-saving and emission-reduction society, devoting to clean production, developing circular economy and realizing sustainable development in China, and has a very broad application space and development prospect. During the production of nanofiltration membranes, a glue coating device is needed to apply glue on the laid membrane sheets according to a track, so that a layer of coated glue is evenly covered on the membrane sheets;

[0004] Chinese Patent Authorization Publication No. CN213914588U discloses a glue coating device for reverse osmosis membrane element production, including a base, a support, a three-axis moving mechanism and a glue applicator. The upper surface of the base is provided with a processing panel, and a guide rail is opened on the upper surface of the base. The side of the processing panel is provided with a guide rail. A support is fixed on the base, and a three-axis moving mechanism is installed on the support. A glue applicator is installed on the three-axis moving mechanism. An electric telescopic rod is fixedly installed on the support. A pressing plate is movably installed on the support. A through hole is opened through the pressing plate. The operating end of the electric telescopic rod passes through the through hole and is fixedly connected to the pressing plate. A counterweight block is arranged at the other end of the pressing plate. After the reverse osmosis membrane is placed on the processing panel, the pressing plate is controlled to rise and fall by the electric telescopic rod, and then the periphery of the reverse osmosis membrane is fixed by the pressing plate, which is convenient for applying glue to the reverse osmosis membrane by the glue applicator;

[0005] The above-mentioned prior art solutions have the following deficiencies: This technical solution drives the glue applicator to move through a moving structure to attach a layer of glue on the membrane surface. However, the outlet of the glue applicator is small, and under this operation, the glue is applied drop by drop on the membrane surface, making it difficult to spread it evenly, which is not conducive to the smooth progress of subsequent processing work. Therefore, we need to further improve it. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a glue coating device for the production of nanofiltration membrane elements based on orientation technology, so as to solve the problem that the glue sprayed in the glue coating device is difficult to level in the above-mentioned background technology.

[0007] To achieve the above object, the present utility model provides the following technical solution: A glue coating device for the production of nanofiltration membrane elements based on orientation technology, including a base, the top of the base is connected with a glue coating table, and the top of the glue coating table is connected with a purification box. Both sides of one end of the glue coating table are connected with support frames, and winding rollers are movably and rotatably connected inside the support frames. A positive and negative thread screw is rotatably connected inside the glue coating table, and first thread sleeves are sleeved on the outer sides of the positive and negative thread screws. A first motor is connected inside the glue coating table on one side of the positive and negative thread screw. The top ends of the first thread sleeves are fixedly connected with orientation frames. The bottom end of the glue coating operation frame is connected with a through pipe, and the bottom ends of the through pipes are connected with glue spray nozzles, and there are six groups of them.

[0008] As a further description of the above technical solution, electric push rods are connected to the top ends of the orientation frames, and movable clamping plates are connected to the bottom ends of the electric push rods. Buffer pads are connected to the bottom ends of the movable clamping plates and the top ends inside the orientation frames. A roller is movably connected between the movable clamping plates. Built-in grooves are provided inside the movable clamping plates, and second threaded rods are rotatably connected inside the built-in grooves. Second thread sleeves are sleeved on the outer sides of the second threaded rods, and the inner sides of the second thread sleeves are fixedly connected with the roller.

[0009] As a further description of the above technical solution, a scraping seat is movably connected to the bottom end of the glue coating operation frame, and the roller horizontally penetrates through the inside of the scraping seat. The scraping seat moves on the outer side of the roller. A connecting block is connected to the bottom end of the scraping seat, and a clamping block is connected to the outer side of the connecting block. A collecting box is connected to one side of the clamping block.

[0010] As a further description of the above technical solution, the connecting block is shaped like an L, and the outer side of the connecting block fits with the inner side of the clamping block.

[0011] As a further description of the above technical solution, the glue spray nozzles are all shaped like horns and are arranged at equal intervals at the bottom ends of the through pipes.

[0012] As a further description of the above technical solution, a conveying box and a purification box are respectively connected to the top end of the glue coating operation frame, and the conveying box and the purification box are connected and communicated through a corrugated conveying pipe.

Activated carbon adsorption nets are filled inside the purification seats outside the partition plates.

[0013] As a further description of the above technical solution, the partition plates are cross-distributed inside the purification base.

[0014] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0015] By starting the first motor to drive the two groups of alignment frames to move synchronously inward, the distance between the two groups of alignment frames can be correspondingly adjusted according to the size of the nanofiltration membrane body. At the same time, by starting the electric push rod to drive the movable clamping plate to move downward, the direction of the movable clamping plate is adjusted to clamp and limit the height of the nanofiltration membrane body according to the thickness of the nanofiltration membrane body, thus completing the alignment function, preventing deviation during the gluing process, which is not conducive to the smooth progress of subsequent work. At the same time, the buffer pad prevents certain damage to the membrane under hard clamping. By starting the second motor and under the action of threaded connection, the roller can be driven to move, and the glue on the surface of the nanofiltration membrane body can be evenly applied, improving the work efficiency and work quality of subsequent pasting or other processing work. At the same time, by installing the scraping seat to move outside the roller, the glue adhered to the outside of the roller can be scraped off and collected in the collection box, which can not only make the next coating work efficient, but also avoid the waste of glue materials;

[0016] By installing the purification box, the pungent smell emitted by the glue can be weakened. The smell emitted by the glue can be filtered through the activated carbon adsorption net, and at the same time, staggering the distribution of the purification bases can effectively extend the purification time, enabling the gas to fully blend with the activated carbon adsorption net, further improving the purification work quality. At the same time, through the catalytic component, the harmful substances in the gas can be purified, thus ensuring the healthy living state of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
