Description

Technical Field

[0001] This utility model relates to the technical field of environmentally friendly polyurethane adhesive production, and in particular to a moisture-proof device for an environmentally friendly polyurethane adhesive production line. Background Technology

[0002] Polyurethane adhesives are high-performance adhesive materials with polyurethane resin as the core component, and they have wide applications in the automotive manufacturing industry. During the production of polyurethane adhesives, components such as isocyanates readily react with water to produce carbon dioxide and polyurea, leading to raw material clumping, abnormal viscosity, or the formation of bubbles, which affects the quality of subsequent processes. Therefore, it is necessary to use moisture-proof devices to dry the polyurethane adhesive production line workshop and reduce the humidity of the air in the workshop. In the prior art, utility model patent application number 201721746731.6 discloses a dehydration device for an air compressor in a production workshop, which mainly consists of an air compressor, a refrigerated desiccant, and a filter. During use, the air compressor sends compressed air into a humid air storage tank and a refrigerated dryer. The refrigerated dryer performs primary drying and dehydration on the compressed air before sending it into a drying tower. The filter on the air supply pipeline between the refrigerated dryer and the drying tower performs two-stage filtration of the compressed air, removing some moisture and impurities. However, it has the following problems during use: as the usage time increases, more and more solid impurities adhere to the filter plates, and it cannot automatically clean these solid impurities, requiring manual cleaning, making it inconvenient to use and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a moisture-proof device for an environmentally friendly polyurethane adhesive production line that facilitates the cleaning of solid impurities in the filtration mechanism by workers, reduces labor intensity, is easy to use, and has high practicality.

[0004] This utility model discloses a moisture-proof device for an environmentally friendly polyurethane adhesive production line, comprising an air dryer, a conveying pipe, and an exhaust funnel. The output end of the air dryer is connected to the exhaust funnel via the conveying pipe. It also includes an air intake mechanism, a conveying mechanism, a filtering mechanism, and a cleaning mechanism. The output end of the air intake mechanism is connected to the filtering mechanism via the conveying mechanism, and the output end of the filtering mechanism is connected to the air dryer. The cleaning mechanism is installed on the filtering mechanism and has a cleaning function. The conveying mechanism has a conveying function, and the filtering mechanism has a filtering function. When drying the air in the polyurethane adhesive production workshop, the conveying mechanism is opened, allowing the air from the production workshop to enter the filtering mechanism via the air intake and conveying mechanisms. The filtering mechanism removes solid impurities from the air, and then the air enters the air dryer for further drying. The dried air is then discharged into the workshop via the conveying pipe and the exhaust funnel, ensuring the workshop's drying effect. When it is necessary to clean the solid impurities adhering to the filtering mechanism, the cleaning mechanism is opened, and the filtered solid impurities are removed. This facilitates the cleaning of solid impurities in the filtering mechanism by workers, reduces labor intensity, and is convenient to use and highly practical.

[0005] Preferably, the air intake mechanism includes a base plate, an electric slide rail, a sliding plate, a mounting plate, and an air intake pipe. The electric slide rail is fixedly installed on the upper end of the base plate, the sliding plate is installed on the electric slide rail, and the electric slide rail is used to raise and lower the sliding plate. The mounting plate is fixedly installed on the sliding plate, and the air intake pipe is fixedly installed on the mounting plate. The air intake pipe is provided with an air inlet, and the output end of the air intake pipe is connected to the conveying mechanism. When it is necessary to dry the air in the workshop, the conveying mechanism is opened, so that the air in the workshop can enter the filter mechanism and the air dryer for drying through the air intake pipe and the conveying mechanism. At the same time, the electric slide rail can be opened, and the electric slide rail drives the sliding plate to adjust the height. The sliding plate adjusts the height of the air intake pipe through the mounting plate, so that the air intake pipe can draw in air at different heights in the workshop, which facilitates uniform drying of the air.

[0006] Preferably, the conveying mechanism includes a conveying pump, a conveying hose, and an air supply pipe. The input end of the conveying pump is connected to the air inlet pipe through the conveying hose, and the output end of the conveying pump is connected to the filtration mechanism through the air supply pipe. When drying the air in the workshop, the conveying pump is turned on, so that the air in the workshop enters the filtration mechanism in sequence through the air inlet pipe, the conveying hose, the conveying pump, and the air supply pipe. Then the air enters the air dryer for drying, which facilitates the delivery of air.

[0007] Preferably, the filtration mechanism includes a support frame, a filter cylinder, a sealing cover, a pipe, a filter plate, and a lifting mechanism. The filter cylinder is fixedly installed on the support frame, and a chamber is provided inside the filter cylinder. The upper end of the filter cylinder chamber is an opening. The sealing cover is installed at the opening at the upper end of the filter cylinder chamber by bolts. The pipe and the air supply pipe are both connected to the chamber of the filter cylinder. The output end of the pipe is connected to the air dryer. The filter plate is located in the chamber of the filter cylinder and is installed on the lifting mechanism. The air supply pipe and the pipe are located on the lower and upper sides of the filter plate, respectively. The air to be dried enters the chamber of the filter cylinder sequentially through the delivery hose, the delivery pump, and the air supply pipe. After being filtered by the filter plate, the air enters the air dryer through the pipe. The filtration of the air by the filter plate reduces solid impurities in the air, thereby achieving the effect of air purification.

[0008] Preferably, the lifting mechanism includes a hydraulic cylinder and a push rod. The hydraulic cylinder is fixedly installed on the upper end of the sealing cover, and the push rod is slidably installed on the sealing cover. The upper end of the push rod is connected to the output end of the hydraulic cylinder, and the filter plate is fixedly installed on the lower end of the hydraulic cylinder. During long-term use, more and more solid impurities will adhere to the lower end of the filter plate. When it is necessary to clean the solid impurities on the lower end of the filter plate, the hydraulic cylinder is opened, and the hydraulic cylinder lowers the filter plate through the push rod, so that the lower end of the filter plate contacts the cleaning mechanism. The cleaning mechanism then cleans the solid impurities adhering to the lower end of the filter plate, improving convenience.

[0009] Preferably, the cleaning mechanism includes a motor, a rotating shaft, and a brush. The rotating shaft is rotatably mounted on the filter cylinder, and its lower end is connected to the output end of the motor. The brush is fixedly mounted on the upper end of the rotating shaft and is located below the filter plate. The lower end of the filter cylinder is provided with an outlet communicating with the filter cylinder chamber. A sealing plate is provided outside the outlet, and the sealing plate is installed on the outside of the outlet by bolts. When it is necessary to clean the solid impurities attached to the lower end of the filter plate, the hydraulic cylinder is opened, and the hydraulic cylinder lowers the filter plate through the push rod until the lower end of the filter plate contacts the brush. Then, the motor is opened, and the motor drives the rotating shaft to rotate. The rotating shaft drives the brush to rotate, and the brush brushes off the solid impurities attached to the lower end of the filter plate during the rotation process, ensuring the filtration efficiency of the filter plate.

[0010] Preferably, the lower end of the push rod is provided with a mounting block, which is fixedly installed on the lower end of the push rod and fixedly installed on the upper end of the filter plate by bolts. When the filter plate is irreparably damaged, the sealing cover is removed from the upper end of the filter cylinder, the old filter plate is removed from the mounting block, and the new filter plate is replaced on the mounting block. This facilitates the replacement of the filter plate.

[0011] Preferably, the filter cartridge is equipped with a cooling plate, with the output end of the cooling plate located inside the chamber of the filter cartridge and the heat dissipation end of the cooling plate located outside the filter cartridge. In the hot summer, when it is necessary to cool the workshop, the cooling plate is turned on to cool the air passing through the chamber of the filter cartridge. The cooled air is then dried and discharged into the workshop. At the same time, the air temperature decreases, reducing the solubility of water vapor, which makes it easier to dry the air and also facilitates the adjustment of the workshop temperature.

[0012] Compared with the prior art, the advantages of this utility model are: it facilitates the cleaning of solid impurities in the filtration mechanism by the staff, reduces labor intensity, is easy to use, and has high practicality. Attached Figure Description

The dried air is discharged into the workshop through the conveying pipe 2 and the exhaust funnel 3, ensuring the drying effect of the workshop. When it is necessary to clean the solid impurities attached to the filtering mechanism, the cleaning mechanism is opened, and the filtered solid impurities are cleaned by the cleaning mechanism. This facilitates the cleaning of solid impurities in the filtering mechanism by the staff, reduces labor intensity, is easy to use, and has high practicality.

[0021] like Figure 1 , Figure 3 and Figure 4 The air intake mechanism includes a base plate 4, an electric slide rail 5, a sliding plate 6, a mounting plate 7, and an air intake pipe 8.

The air intake pipe 8 is provided with an air inlet, and the output end of the air intake pipe 8 is connected to the conveying mechanism. When it is necessary to dry the air in the workshop, the conveying mechanism is opened, so that the air in the workshop can enter the filter mechanism and the air dryer 1 through the air intake pipe 8 and the conveying mechanism for drying. At the same time, the electric slide rail 5 can be opened, and the electric slide rail 5 drives the sliding plate 6 to adjust its height. The sliding plate 6 adjusts the height of the air intake pipe 8 through the mounting plate 7, so that the air intake pipe 8 can draw in air at different heights in the workshop, which facilitates uniform drying of the air.

The filter plate 16 is located in the chamber of the filter cylinder 13 and is installed on the lifting mechanism. The air supply pipe 11 and the pipe 15 are located on the lower and upper sides of the filter plate 16, respectively. The air to be dried enters the chamber of the filter cylinder 13 sequentially through the delivery hose 10, the delivery pump 9, and the air supply pipe 11. After being filtered by the filter plate 16, the air enters the air dryer 1 through the pipe 15. The filtration of the air by the filter plate 16 reduces the solid impurities in the air, thus achieving the effect of air purification.

[0024] like Figure 3 The lifting mechanism includes a hydraulic cylinder 17 and a push rod 18. The hydraulic cylinder 17 is fixedly installed on the upper end of the sealing cover 14, and the push rod 18 is slidably installed on the sealing cover 14.

Then, the motor 19 is opened, and the motor 19 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the brush 21 to rotate. During the rotation, the brush 21 brushes off the solid impurities attached to the lower end of the filter plate 16, ensuring the filtration efficiency of the filter plate 16.
