[0022] Embodiment: a kind of high-efficiency drying device for ultrafiltration membrane wire processing and production, as shown in Figures 1-5 As shown in the figure, including drying bin 1, heating assembly 2, fan 3, backflow pipe 4, exhaust pipe 6, water tank 7 and drying assembly, heating assembly 2 is installed in drying bin 1, heating assembly 2 is located in the middle of drying bin 1, and heat is radiated to the four directions, three fans 3 are installed on the top of drying bin 1, and hot and humid air in drying bin 1 is discharged outward, the outer side of drying bin 1 is connected with arc backflow pipe 4, fan 3 is located at one end of backflow pipe 4, and air outlet 5 is arranged at the other end of backflow pipe 4, backflow pipe 4 is closely attached to three sides of drying bin 1, enough contact area is ensured, and air outlet 5 is small, the air outlet rate is limited, the time of hot and humid air staying in backflow pipe 4 is prolonged, drying bin 1 is connected with exhaust pipe 6, the inlet of exhaust pipe 6 is communicated with the air outlet 5 of backflow pipe 4, the bottom of exhaust pipe 6 is connected with water tank 7, water tank 7 is provided with water outlet 71, the water outlet 71 is provided with sealing plug, the water outlet 71 is blocked by sealing plug during the accumulation process, the drying assembly for drying gas is arranged in exhaust pipe 6, hot and humid air is discharged from drying bin 1 by fan 3, enters backflow pipe 4, flows into exhaust pipe 6 after passing through air outlet 5, and is discharged into air after drying in exhaust pipe 6.

[0023] As shown in Figure 3 And Figure 5As shown, the drying assembly comprises a rack 8, an extrusion plate 9, an electric slide rail 10 and filter cotton 11. The rack 8 is slidably connected in the exhaust pipe 6 and is fixed by screws. The top and bottom of the rack 8 are provided with through holes through which water vapor and water flow can pass. The rack 8 is slidably connected with the extrusion plate 9 on the left and right sides. The electric slide rail 10 is installed on the bottom and top of the rack 8 and is used to drive the left and right movement of the extrusion plate 9 on both sides. The filter cotton 11 is arranged between the extrusion plate 9 and the rack 8. The electric slide rail 10 drives the extrusion plate 9 on both sides to move towards the middle and extrude the filter cotton 11. The extruded water flows into the water tank 7 through the through hole in the bottom of the rack 8, ensuring that the drying effect of the filter cotton 11 is restored. This process realizes the reuse of the filter cotton 11 and prolongs its service life.

[0024] As shown in Figure 5 It also includes a sealing gasket 12. The side of the rack 8 in contact with the exhaust pipe 6 is provided with a sealing gasket 12. The sealing gasket 12 can effectively prevent gas from leaking from the gap, ensuring that the hot and humid air is completely dehumidified by the filter cotton 11, improving the efficiency and stability of the drying assembly.

[0025] As shown in Figure 3 It also includes an insulating plate 13. The outer side of the return pipe 4 is wrapped with an insulating plate 13. On the one hand, the insulating plate 13 can keep the return pipe 4 warm and reduce heat loss, improving the utilization rate of heat energy.

[0026] As shown in Figure 1 It also includes a controller 14 and a humidity sensor 141. The controller 14 is installed on the top of the exhaust pipe 6 and is provided with a humidity sensor 141 towards the middle of the exhaust pipe 6. The controller 14 is wiredly connected with the electric slide rail 10. When the exhaust humidity approaches the set humidity threshold, the electric slide rail 10 is turned on by the controller 14. This process does not require manual intervention, realizes the automatic operation of the drying assembly and improves the intelligent level of the equipment.

[0027] As shown in Figure 5 It also includes a handle 15. The handle 15 is connected to the front side of the rack 8. The design of the handle 15 simplifies the operation process and improves the maintainability of the equipment.

[0028] During the drying process, the hot air dries the ultrafiltration membrane wire, and the moisture is discharged. The high-humidity hot air is discharged to the return pipe 4 through the fan 3, and the hot and humid air circulates in the return pipe 4. The remaining heat can heat the drying bin 1, thereby maintaining the temperature of the drying bin 1. The working power of the heating assembly 2 can be adjusted to save energy consumption. When the gas enters the exhaust pipe 6 through the gas outlet 5, the humidity sensor 141 at the top of the exhaust pipe 6 monitors the humidity of the exhaust gas in real time. When the humidity approaches the set threshold value, the controller 14 starts the electric sliding rail 10 to drive the extrusion plate 9 to extrude the filter cotton 11. The filter cotton 11 absorbs the moisture in the gas, thereby reducing the humidity of the exhaust gas. When the humidity approaches the humidity threshold value, the controller 14 automatically opens the electric sliding rail 10, and the electric sliding rail 10 drives the extrusion plates 9 on both sides to move towards the middle, thereby extruding the filter cotton 11 and squeezing out the moisture. The water flows downwardly into the water tank 7, thereby ensuring the filtering effect of the filter cotton 11, which can be used for a long time. After a period of use, the worker regularly opens the sealing plug of the water outlet 71 to discharge the accumulated water in the water tank 7.

[0029] When the filter cotton 11 needs to be replaced, the handle 15 is pulled out of the placing rack 8, and then the filter cotton 11 is taken out for replacement. After the placing rack 8 is pushed into the exhaust pipe 6, it is fixed by screws. The sealing gasket 12 can ensure the sealing between the placing rack 8 and the exhaust pipe 6.
